CHILD MORTALITY
Over the past decades, child mortality has reduced significantly. Estimates from the United Nations illustrate that there has been a global decline in the under‐five mortality of 53 percent; from 91 deaths per 1,000 live births in 1990 to 43 in 2015.1‐2 Despite these changes, 5.9 million children died before their fifth birthday in 2015 (i.e., more than 16,000 deaths a day), mostly from preventable diseases.2 Infectious diseases, also known as transmissible or communicable diseases, accounted globally for more than half of the under‐five deaths, followed by deaths during or shortly after birth. Of the infectious diseases, pneumonia is the leading cause of the under‐five mortality attributing to 16% of all child deaths, followed by diarrhoea (9%) and malaria (5%). Nutritional status influences these outcomes; about 45 percent of the under‐five mortality is attributable to under‐nutrition.1‐5 Of the children under the age of five, the incidence of infectious diseases is the highest for those under the age of 2; more specifically 81% of the deaths due to pneumonia occur within the first two years of a child’s life.6 Figure 1.1 shows the differences in causes of under‐five mortality between high‐ and low‐income countries, illustrating that as income levels within countries decrease, the proportion of deaths due to infectious diseases increases.

Of all children, a child living in sub‐Saharan Africa is most likely to die before the age of five, where on average 1 out of every 8 children dies before their fifth birthday.2 Huge differences are seen in the chance of survival within and between these countries, where Angola has the highest mortality rate (157 per 1,000 live births) and Seychelles the lowest (14 per 1,000).1‐2 Figure 1.2 shows the differences in mortality by country.

One of the reasons for child mortality to decline over the past decades is due to an increase in coverage of effective health interventions. These interventions focus not only on increasing access to care upon the onset of an illness (i.e., more effective and affordable treatments), but also on measures which prevent children from becoming ill in the first place (e.g., clean water, sanitation, education, improved nutrition and vaccinations).2‐4 While improved access to these interventions has saved a lot of lives, especially children living in isolated and marginalized settings still fail to reach them.7 Not only do these children fail to access preventive measures, but upon illness they also often fail to reach acceptable, affordable and appropriate health care, in time.
10 General introduction
ACCESS TO CARE
To know how to increase coverage of these interventions for children in sub‐Saharan Africa, especially amongst those who currently fail to reach them in time, is important. To do so, donors and policy makers need to understand the underlying determinants which prevent children from accessing these interventions in the first place. The model of ‘three delays’ has been used to help untangle challenges associated with care seeking. The model focuses on delays in accessing care, as the understanding is that the chance to survive is linked to the timelines in which care is received.8 In this thesis, the model will be applied to assess the challenges associated with delays in accessing care for children, more specifically those with symptoms of pneumonia (also referred to as ‘suspected pneumonia cases’). While the model was initially designed to categorize factors affecting the onset of obstetric complications and its outcomes, it is not the first time it is used to assess child health outcomes.9‐10 Analyses based on such modelling help create a more comprehensive understanding of why care is – or is not sought in time. This as it looks at challenges at household, as well as facility level. This is needed, as the children accessing care represent only a subset of all the children actually requiring health services. Hence delays which occur at home need to be examined too – even more so in sub‐Saharan African settings, where sick children often fail to reach the formal health system.10
How challenges in accessing care can be captured by three stages of delays Thaddeus and Maine designed the model of three phases of delay, which was first presented in 1994.8 The three phases are as followed; 1. The delay in deciding to seek care on the part of the individual, the family or both, which can be influenced – amongst others – by the status of women; distance from the health facility; costs; poor recognition and/or understanding of the illness (to assess the complications and/ or risks); previous experiences; and perceived quality of care. 2. The delay in reaching an adequate health care facility, which is mostly determined by geographical aspects, such as the distribution of facilities and the conditions of the road. 3. And, the delay in receiving adequate health care at the health facility, which can be influenced by poor quality and lack of resources as a result of inadequately trained and/ or motivated staff; out‐of‐stocks; inadequate referral systems; etc.
As the chance to survive is linked to the timelines in which care is received, it is evident that in areas where mortality is high, coverage of effective interventions is insufficient.
11 Chapter 1
Therefore, the analyses of care seeking behaviour, based on the model of three delays, can help improve programming to ensure more effective coverage of life‐saving health interventions.11 To date, little is known on how these delays affect care seeking behaviour across high mortality countries in sub‐Saharan African countries, to which extent care seeking patterns are similar, and what lessons learned and potential best practices are which should be shared across resource limited settings.
Leveraging mobile technology to reduce delays in accessing care To improve coverage of effective programs, it is not only important to understand what the existing challenges are, but also to identify ways in which these can be overcome. With mobile phone users increasing almost a three‐fold between 2005 and 2010 and reaching 367 million subscribers in mid‐2015 in sub‐Saharan Africa,12 there are high expectations that this technology can help connect isolated communities and healthcare services, thereby reducing delays in accessing care. The use of mobile phones to improve access to health is referred to as mHealth. Over the past decade, mHealth initiatives have focussed on addressing various aspects of the three phases of delay; for example by focussing on increasing knowledge, providing financial support, strengthening provider‐to‐provider communication systems, data collection methods, and ‐ amongst others – strengthening the supply chain management.13 Nevertheless, there is limited evidence on how mobile phones can most affectively address these delays, with only few evaluating the effectiveness of these initiatives in resource limited settings.14‐19 Finally, while the expectations are high, little is known on why these initiatives fail to go to scale in rural settings in sub‐Saharan Africa.20
Problem statement In summary, in sub‐Saharan African countries most children die of preventable and treatable illnesses because they fail to reach acceptable, affordable and appropriate health care in time. Pneumonia is responsible for most of these deaths. The extent to which the three phases of delay ‐ (deciding to seek, as well as reaching and receiving care) ‐ affect care seeking for children in sub‐Saharan African settings is yet unknown. While mobile technology appears to present great opportunities to address these delays, there is still little evidence on how this technology can best be used to improve access to health care. A better understanding of these delays and the potential of mHealth initiatives can help to identify programmatic coverage with their successes and challenges, as well as to identify opportunities.21‐22
12 General introduction
AIM, SCOPE AND OUTLINE OF THIS THESIS
Aim The aim of this thesis is to expand the knowledge on the three phases of delays in accessing health care, and to assess if and how the rapidly expanding field of mHealth can decrease these delays in order to improve programmatic coverage of effective health interventions across various settings in sub‐Saharan Africa. The specific objectives, which this thesis aims to answer, are: 1. How do the delays in care (deciding to seek, as well as reaching and receiving) affect care seeking behaviour across sub‐Saharan Africa? And, how can better knowledge of these delays lead to improved programming? This thesis seeks to improve the knowledge on these questions by focussing on the exemplary condition of pneumonia. 2. What is the potential of mobile technology to improve health outcomes by addressing the delays in accessing care, in resource limited settings? And, what are programmatic challenges in implementing mHealth strategies?
Scope To investigate the three phases of delays in all its complexity is far beyond the scope of a single thesis. Nevertheless, all three delays are considered in this thesis as these can adversely affect child health outcomes in sub‐Saharan Africa. A better understanding of de magnitude of each of these delays is therefore relevant for policy makers and programmers; especially those working in resource limited settings. To enable an assessment of all three phases of delays, the complexity of each delay is reduced to manageable proportions. In other words, in order not to state generalities, the strategy of this thesis is to give exemplary case studies for each delay, to illustrate the complexities at hand. For example, the first delay – deciding to seek care – is influenced by more than just knowledge; nevertheless, this thesis only assesses the association between knowledge and care seeking. In general, the focus of this thesis is on children under the age of five, living in sub‐ Saharan Africa settings with high mortality rates. More specifically, the first three chapters will focus on pneumonia; globally the main cause of childhood mortality.
13 Chapter 1
Outline This thesis is built around two main parts, namely a section which addresses the three phases of delay (Part II) and a section which assesses the potential of mobile phones as a solution (Part III). Part II, the section on the three phases of delay in care, is built around three chapters. Each chapter focusses on one of the phases of delay. The first chapter analyses causes of the delay in deciding to seek care (Chapter 2). This assessment is based on national survey data from countries in sub‐Saharan Africa, and assesses the correlation between knowledge of pneumonia symptoms and care seeking behaviour. The second chapter analyses the causes of the delay in reaching care (Chapter 3). As there are many reasons why care is not reached in time, this chapter starts with assessing to which care providers caregivers take their child and what influences this. This assessment is also based on national survey data, focussing on care seeking behaviour for children under five with symptoms of pneumonia. The third, and last chapter of this section, focusses on the delay in receiving adequate health care (Chapter 4). This delay can be caused by a myriad of reasons often linked to a poor quality and lack of resources. As mentioned, one of the reasons is inadequately trained staff. For this chapter, data were analysed from five different international organizations working in resource limited settings in sub‐Saharan Africa. The focus of this chapter is on the accuracy of community health workers in classifying breathing rates and the effect of counting beads in helping them to overcome key challenges related to classifying them. Part III, the section a potential solution, is built around three chapters all three focusing on the use of mobile phones. The first chapter is an assessment on the potential of mobile phones to improve access to health services in resource‐limited settings (Chapter 5). This assessment is based on a literature review and focusses on the evidence regarding the impact of mobile phones to improved maternal and new‐born health focussing on each phase of delay. The second chapter of part III investigates the impact of a mHealth initiative in improving care seeking behaviour in Malawi. The initiative is a toll‐free hotline and mobile messaging service, which connects caregivers to health workers and health information (Chapter 6). The last chapter of this section assesses what the key challenges are in relation to scaling‐up mHealth interventions (Chapter 7). This assessment is based on two case studies, nutrition surveillance and early infant diagnosis of HIV, in Malawi and Zambia. The last part of this thesis is the general discussion, which will focus on how improved knowledge of the delays and mHealth can help identify programmatic coverage with its successes and challenges.

ABSTRACT
Pneumonia is the main cause of child mortality world‐wide and most of these deaths occur in sub‐Saharan Africa (SSA). Treatment with effective antibiotics is crucial to prevent these deaths; nevertheless only 2 out of 5 children with symptoms of pneumonia are taken to an appropriate care provider in SSA. While various factors associated with care seeking have been identified, the relationship between caregivers’ knowledge of danger signs and actual care seeking for their child with symptoms of pneumonia is not well researched. Based on data from Multiple Indicator Cluster Surveys, we assessed the association between caregivers’ knowledge of symptoms related to pneumonia – namely fast or difficulty breathing – and care seeking behaviour for these symptoms. We analysed data of 4,163 children with symptoms of pneumonia and their caregivers. Across all 6 countries only around 30% of caregivers were aware of at least one of the two symptoms. We found no association between caregivers’ knowledge of danger signs and actual care seeking for their child with symptoms of pneumonia in Central African Republic, Chad, Malawi, and Sierra Leone. Our study shows that in the Democratic Republic of the Congo and Nigeria the association between knowledge and care seeking was significant (P≤0.01), even after adjusting for key variables (including wealth, residence, education). These findings reveal an urgent need to increase community awareness of danger signs and symptoms of pneumonia, while simultaneously designing context specific strategies to address the fundamental challenges associated with timely care seeking.
20 Associations between knowledge and care seeking behaviour
INTRODUCTION
Pneumonia is responsible for more deaths among children under five years of age than any other infectious disease. In 2015, pneumonia killed an estimated 922,000 children under‐five globally; most of these deaths were in sub‐Saharan Africa.1 Timely treatment with effective antibiotics is critical to prevent pneumonia‐related deaths.2 Unfortunately, early care seeking for childhood illnesses remains a challenge in countries with high mortality rates.3‐6 Estimates from sub‐Saharan Africa indicate that only 2 out of the 5 children with pneumonia specific symptoms are taken to an appropriate provider for care.1 Key factors associated with care seeking include household income,3,6‐7 education levels of the primary caregiver,7 limited caregivers’ recognition of the disease,8 younger age and sex of the child,7 geographical areas (including rural locations)3 and religion.9 In addition, a systematic review of studies conducted across sub‐Saharan Africa identified cultural beliefs and illness perceptions, perceived severity of the illness, previous experience with health services, habit, treatment costs and efficacy, and gender as key factors for care seeking.3 As failure to recognize an illness is expected to leading to delays in care seeking, the first step to address pneumonia specific mortality is by ensuring that caregivers are aware of pneumonia specific symptoms.10 To date, the relationship between specific knowledge of these symptoms, recognition of them and related care seeking is not well researched.8 And, only a few studies specifically focus on the association between knowledge of symptoms related to pneumonia – namely fast or difficulty breathing – and care seeking behavior.11,12 We hypothesize that knowledge of these specific symptoms will enable caregivers to recognize an illness, consequently seeking timely and appropriate care. Such information is critical to plan effective strategies to reduce pneumonia mortality in high‐burden settings, particularly where rates of care seeking are inadequate.
METHODOLOGY
Data sources Our analyses are based on data from Multiple Indicator Cluster Surveys (MICS) conducted in sub‐Saharan Africa. These nationally representative household surveys are conducted by national implementing agencies with the support of the United Nations Children’s Fund (UNICEF). MICS surveys collect statistically sound and internationally comparable data on a variety of topics related to maternal and child
21 Chapter 2 health, including knowledge of symptoms (also referred to as danger signs) of childhood illnesses and care seeking behaviour for children under the age of five years.13.14 Sub‐Saharan African countries were selected for inclusion in this study if they had a MICS conducted during or after 2010, the data was national representative, and the datasets were available upon the start of our analyses (August 2015). Information on knowledge of symptoms of childhood illnesses is obtained during interviews using the ‘individual women’s’ questionnaire, which is administered to women age 15 through 49 years. Data on care seeking behaviour are obtained via the ‘children under‐ five’ questionnaires, which is administered primarily to mothers of children under the age of five years. When the mother is deceased or is living elsewhere, the questionnaire is administered to the child’s primary caregiver.
Survey methods and ethics Sampling frames are usually based on the most recent national census and therefore do not include non‐household populations; i.e. they exclude populations living in group quarters (e.g. hospitals, military barracks) and those living on the street. Usually, a two‐ stage cluster sampling approach is used; the first stage: select enumeration areas and do a listing of households, second stage: select households from list. While the surveys are conducted in different countries ‐ and may therefore vary due to limitations in costs and practical considerations (including security) ‐ all surveys ‘adhere to the fundamentals of scientific sampling, including complete coverage of the targeted population, use of suitable sample size, the need to conduct household listing and pre‐ selection of sample households’.13 Implementing agencies are required to obtain ethical approval as abide by the laws of the country. Survey tools, datasets and more detailed information on country specific survey methods can be found on the MICS website.14
Research questions For each country, we first assessed the proportion of caregivers (either mothers, or primary caregivers) of children under‐five that mentioned one or both symptoms of childhood illnesses linked to pneumonia, i.e. fast and/ or difficulty breathing, as a reason to seek care. The specific interview question asked to caregivers is the following open‐ended question: “Sometimes children have severe illnesses and should be taken immediately to a health facility. What types of symptoms would cause you to take a child under the age of 5 to a health facility right away?” A subsequent probe question asked: “Any other symptoms?” The responses were categorized as: child is not able to drink or breastfeed; becomes sicker; develops a fever; has fast breathing; has difficulty in breathing; has blood in stools; is drinking poorly; any other (unspecified); and some countries included categories such as diarrhoea and/ or vomiting. We classified caregivers who were able to identify either fast or difficulty breathing as having
22 Associations between knowledge and care seeking behaviour knowledge of pneumonia symptoms. As responses were not categorized as “cough” or “chest in‐drawing,” we were not able to include these symptoms in our analysis of pneumonia specific knowledge. Second, we calculated how many of these caregivers reported that their child had a cough and fast or difficulty breathing due to a problem in the chest in the past two weeks, as cases with symptoms of pneumonia. The interview questions related to these cases are: “Has (name) had an illness with cough at any time in the last 2 weeks?” “When (name) had an illness with cough, did he/she breathe faster than usual with short rapid breaths or have difficulty breathing?” “Was the fast or difficult breathing due to a problem in the chest or to a blocked or runny nose?” The children of whom the caregiver reported that they had a cough with fast or difficulty in breathing, due to a problem in the chest in the past two weeks, where considered as cases with symptoms of pneumonia. Third, we assessed which proportion of these caregivers brought their child to an appropriate health provider. The interview questions related to care seeking are: “Did you seek advice or treatment for the illness from any source?” “Where did you seek advice or treatment?” A subsequent probe asked, “Anywhere else?” We defined ‘appropriate’ health care provider as one working at either a private or public hospital, primary health care facility or any other government service, and who has undergone formal training and received accreditation, authorizing them to treat children with signs of acute respiratory tract infections.7 Once we knew which proportion sought appropriate care, we assessed if the caregivers who mentioned at least one pneumonia specific symptom as reasons to seek immediate care – i.e. fast or difficulty breathing – were indeed more likely to seek care from these providers, as supposed to those who did not mention one of these symptoms.
Data analysis We conducted our analyses using SPSS version 21. The data analysis was conducted by two independent researchers [CN and PH]. We first created a new dataset by merging the two (i.e. the ‘individual women’s’ and ‘children under‐five’) data files, matching eligible cases for both surveys based on cluster, household and line number. For caregivers with more than one child under the age of five, we used the files of the youngest child ‐ in the case of twins we kept the child that was mentioned last. We weighted the data using the sample weight variables. Cases with missing data (i.e. surveys which were party completed, as well as missing variables needed for these analyses) were excluded from the analyses. We calculated the percentage of caregivers included in the merged dataset who reported fast or difficulty breathing as reasons to
23 Chapter 2 seek immediate care from a health facility. We then calculated cross tabulations and performed chi‐square tests to assess the association between care seeking and knowledge of at least one symptom (i.e. fast or difficulty breathing). Based on the literature on care seeking, we included the following variables in the multivariate analyses: household wealth quintile (poorest, poorer, middle, richer and richest); residence (rural, urban); caregiver’s age (15‐19, 20‐24, etc.) and their level of education (none, primary, and secondary or higher); child age (< 2 years, 2‐5 years) and their sex (boy, girl); and the total number of children ever born (<2, 2‐3 and 4+). When possible we also adjusted for geographical location (regions) and religion. With the categories for the last two variables being country specific, not always included in the datasets, and – in some cases – sample size restrictions, we pre‐defined some parameters for these variables when available in the dataset: 1) the sample has to be large enough (≥10 cases per category); 2) geographical location has to refer to regions e.g. the North, East, South or West and not to any other groupings (i.e. provinces, or districts), and 3) we first assess if we can include geographical location (regions), after which we conduct the same assessment for religion. We performed a multivariate logistic regression for the dependent variable (care seeking from an ‘appropriate’ health provider) and the independent variables, in order to examine the association. We then calculated the adjusted odds ratios (ORs) with corresponding 95% confidence intervals (CIs).
RESULTS
Of countries in sub‐Saharan Africa, in which a MICS was conducted during or after 2010 and for which survey results were available before the start of our analyses, we selected the six countries with the largest sample sizes for analysis: Central African Republic (CAR), Chad, Democratic Republic of the Congo (DRC), Malawi, Nigeria, and Sierra Leone. Four surveys were from 2010 (CAR, Chad, DRC and Sierra Leone), Nigeria’s survey was from 2011 and Malawi’s was from 2013‐14.
Background characteristics Table 2.1 shows the samples per country, after merging the women’s and children’s datasets, with Nigeria as the largest sample (N=16,242) and Sierra Leone as the smallest (N=6,033). The vast majority of caregiver‐child combinations included in the analyses across the six countries live in rural settings, and most of the caregivers have at least four children.

The largest differences across the countries are found in levels of education, with most caregivers having had no education in Chad (73.8%), Sierra Leone (71.2%) and Nigeria (42.0%) and at least primary school in Malawi (69.6%), DRC (42.7%) and CAR (42.6%). The percentage of cases with symptoms of pneumonia (i.e. those for whom the mother or caregiver mentioned that their child had a cough and fast and/or difficulty breathing due to a problem in the chest in the past two weeks) ranged from 3.7% (n=607) in Nigeria to 9.6% (n=947) in Chad (Table 2.1). Hence, in the total population we had 4163 cases with symptoms of pneumonia.
Knowledge of fast and/or difficulty in breathing Of the two symptoms linked to pneumonia, caregivers were most aware of the symptom ‘difficulty in breathing’, ranging from 17.4% of the sample in Chad to 24.0% in CAR (Table 2.2). Across all 6 countries around 30% (ranging from 29.2‐32.9%) of caregivers were aware of at least one of the two symptoms. We characterised these caregivers as caregivers with appropriate knowledge of danger symptoms for pneumonia, see Table 2.2. When assessing the percentage of caregivers who mentioned both symptoms, this ranged from 4.5% in Chad to 11.2% in CAR.

Care seeking behaviour Table 2.3 shows the associations between knowledge of at least one symptom for pneumonia and care seeking from appropriate health care providers, also with adjustments for the predefined variables in a multivariate logistic regression model. Of children with symptoms of pneumonia in the previous two weeks, those living in Sierra Leone and Malawi were most likely (73.2% and 68.8%, respectively) to be brought to an appropriate provider. In Chad and CAR this was only 27.4% and 30.9%, respectively. Care seeking was only moderately better in Nigeria (41.9%) and DRC (44.2%).

In DRC, a child whose caregiver mentioned at least one symptom related to pneumonia as reasons to seek immediate care was 1.9 times more likely to have been brought to an ‘appropriate’ health provider during his or her last illness than a child whose caregiver did not mention one of the symptoms (95% CI = 1.3‐2.7, P≤0.01). The association remained largely the same after adjusting for wealth, residence, maternal age and education, the age and sex of the child, and number of children ever born

(OR=2.0, 95% CI = 1.3‐3.0, P≤0.01). A significant association was also found in Nigeria, where caregivers with knowledge of symptoms were 1.6 times more likely to seek care from an ‘appropriate’ health provider (95% CI = 1.1‐2.2, p≤0.01). After adjusting for the pre‐defined variables as mentioned for DRC, and for religion (Muslim, Christian) and geographical location (6 regions; north‐east, north‐west, south‐south, south‐east, south‐west, north‐centre) the OR increased to 1.9 (95% CI = 1.3‐2.9, p≤0.01). For the other four countries, the analyses reveal no significant association between knowledge and care seeking.
DISCUSSION
In this study, we found low levels of caregivers knowledge of symptoms related to childhood pneumonia in sub‐Saharan Africa; on average only around 30% of caregivers were aware of either fast or difficulty in breathing as a reason to seek care. These caregivers, who were aware of at least one of these symptoms, were not necessarily more likely to seek care from an appropriate health care provider. We found a significant association between knowledge of at least one symptom and care seeking in DRC and Nigeria. This association was evident even after adjusting for key background characteristics. For the other four countries (CAR, Chad, Malawi and Sierra Leone) the associations were not significant. Our analyses also reveal large differences in care seeking for children with symptoms of pneumonia, ranging from 27% in Chad to 73% in Sierra Leone.
Low levels of knowledge of pneumonia specific symptoms are confirmed by other studies, even compared to knowledge of other illnesses such as malaria and diarrhoea.15,16 Of the two symptoms, we found that caregivers more frequently mentioned difficulty in breathing as compared to fast breathing. A study conducted in Nigeria found that mothers were more likely to recognise pneumonia based on fever and cough, than on either fast or difficulty breathing.17 This same study also found that mothers were less likely to recognize pneumonia based on more severe symptoms such as chest in‐drawing and central cyanosis.17 Studies conducted in Sierra Leone18 and Nigeria11 also report a lack of knowledge on symptoms and that caregivers are often not aware of ways to prevent or treat common childhood illnesses, including pneumonia.
Other studies also conclude that care seeking patterns vary between and within countries, as they are linked to a dynamic process influenced by a range of socio‐ economic, cultural and geographic access factors.3,7,19‐21 More specifically, a study from
28 Associations between knowledge and care seeking behaviour
Malawi confirms that wealth, urban‐rural residence, maternal education ‐ amongst others ‐ were associated with care seeking.22 Studies also report that care seeking is linked not only to the ability of caregivers to recognize an illness, but also to caregivers’ perception of the severity of the illness: the more severe caregivers’ perceived the illness, the more likely they were to seek care.8,23 The complexity of factors that influence care seeking behaviour could explain the fact that we found no significant association between knowledge of symptoms and care seeking behaviour in most of the countries included in these analyses. While this is concerning, other studies have shown that knowledge alone is insufficient to change behaviour; e.g. knowledge of the importance of using a condom to reduce the risk of HIV transmission, does not necessarily translate to higher use of condoms amongst those most at risk.24 Other studies also found that community based approaches such as provision of integrated case management of childhood illnesses ‐ including pneumonia ‐ can be an important strategy.25,26 A study from Nigeria27 showed that community information activities for malaria lead to improved knowledge, home management and referral practices.
Limitations There are some limitations related to these analyses. The children with symptoms of pneumonia are based on caregivers’ perceptions of symptoms and their ability to recall events, which could lead to incorrect estimates.28 In relation to this, we were not able to assess if knowledge of pneumonia specific symptoms lead to more accuracy in the recognition of pneumonia specific symptoms, subsequently leading to better identification of suspected cases; or, as the cases are not clinically validated as those requiring medical care, not seeking care might in some cases be justified. Also, we were not able to disaggregate the data by severity of the illness, or by the severity of symptoms (e.g. chest in‐drawing). And, as caregivers were not prompted about specific symptoms, it is possible that pneumonia specific symptoms just did not come to mind when interviewed, this could have led to under reporting of these specific symptoms. Finally, we were not able to discern where caregivers learned about symptoms of childhood illnesses and whether or not they learned this after care seeking for the child’s last illness. A study from Nigeria29 showed that only 23% of the caregivers received health information from the healthcare providers after being hospitalized.
Conclusion We hypothesized that knowledge of disease specific symptoms improves the ability of caregivers to recognize an illness and seek appropriate care and found low levels of knowledge on pneumonia among caregivers in six high burden countries in sub‐Saharan Africa. However, we found limited associations between knowledge and care seeking in
29 Chapter 2 this study, which suggests that knowledge alone is not sufficient to take action. With low levels of knowledge of symptoms of pneumonia across these high pneumonia mortality settings, emphasis should be put on education programs, which not only focus on the primary caregivers, but on all those involved in decision‐making processes and care seeking. In addition, factors other than knowledge (e.g. empowerment, costs) should also be addressed to improve care seeking behaviour. In other words, there is a need to increase community awareness of pneumonia, while simultaneously designing context specific strategies to address the fundamental challenges associated with timely care seeking.

ABSTRACT
Pneumonia is the leading cause of childhood mortality in sub‐Saharan Africa (SSA). Because effective antibiotic treatment exists, timely recognition of pneumonia and subsequent care seeking for treatment can prevent deaths. For six high pneumonia mortality countries in SSA we examined if children with suspected pneumonia were taken for care, and if so, from which type of care providers, using national survey data of 76530 children. We also assessed factors independently associated with care seeking from health providers, also known as ‘appropriate’ providers. We report important differences in care seeking patterns across these countries. In Tanzania 85% of children with suspected pneumonia were taken for care, whereas this was only 30% in Ethiopia. Most of the children living in these six countries were taken to a primary health care facility; 86, 68 and 59% in Ethiopia, Tanzania and Burkina Faso respectively. In Uganda, hospital care was sought for 60% of children. 16‐18% of children were taken to a private pharmacy in Democratic Republic of Congo (DRC), Tanzania and Nigeria. In Tanzania, children from the richest households were 9.5 times (CI 2.3‐39.3) more likely to be brought for care than children from the poorest households, after controlling for the child’s age, sex, caregiver’s education and urban‐rural residence. The influence of the age of a child, when controlling for sex, urban‐rural residence, education and wealth, shows that the youngest children (<2 years) were more likely to be brought to a care provider in Nigeria, Ethiopia and DRC. Urban‐rural residence was not significantly associated with care seeking, after controlling for the age and sex of the child, caregivers education and wealth. The study suggests that it is crucial to understand country‐specific care seeking patterns for children with suspected pneumonia and related determinants using available data prior to planning programmatic responses.
34 Care seeking behaviour for children with suspected pneumonia
INTRODUCTION
Acute respiratory infections (ARIs) are the most common illnesses in childhood, of which lower respiratory tract infections (LRTIs) are the most severe in developing countries.1 Pneumonia, a common and severe LRTI, was responsible for 15% of all deaths among children under‐five in sub‐Saharan Africa (SSA) in 2013 and most of these deaths were concentrated in a few countries.2‐4 Cough and fast and/ or difficult breathing (i.e. tachypnea and/or dyspnea) due to a problem in the chest are clinically recognized as signs of childhood pneumonia.5 Effective antibiotic treatment for pneumonia exists, and therefore timely recognition of these signs and symptoms by primary caregivers and subsequent care seeking for treatment from ‘appropriate’ providers can prevent many of these deaths.6 Nevertheless, only 50% of children in SSA with suspected pneumonia were taken for care in 2010.7 Caregivers may not seek care for myriad reasons: both financial (e.g., the cost of services or treatment, transportation costs, loss of wages) and non‐financial (e.g., gender and social norms, insufficient knowledge of danger signs and illness severity, and previous experiences with health services).8‐11 Further analysis of care seeking behaviours by primary caregivers, and on child, caregiver and household characteristics associated with care seeking is needed to further optimise future strategies within integrated approaches to prevent and treat childhood pneumonia.12 We examined care seeking behaviour by caregivers of children under‐five years of age with suspected pneumonia in sub‐Saharan countries with high rates of childhood pneumonia mortality, and examined to what extend caregivers and household characteristics influenced care seeking.
METHODOLOGY
Data sources We analysed data from the Demographic and Health Surveys (DHS) or Multiple Indicator Cluster Surveys (MICS) of countries in sub‐Saharan Africa identified by the Global Action Plan for Pneumonia and Diarrhoea (GAPPD) as being among those with the highest burden for pneumonia.12 DHS and MICS surveys are typically conducted by government statistics agencies every 3 to 5 years, with the support and technical assistance of the United States Agency for International Development (USAID) and the United Nations Children's Fund (UNICEF) respectively. Both surveys are relatively similar in content and scope and have comparable results. DHS and MICS survey programs enable low‐and middle‐income countries (LMICs) to produce estimates of a range of indicators in the areas of health, education, child protection and HIV & AIDS.
35 Chapter 3
DHS and MICS work together to harmonize tools and methods to enable comparisons of key indicators across countries and over time. Both surveys adhere to the fundamentals of scientific sampling, including complete coverage, suitable sample sizes, pre‐selection of sample households, and sample documentation. However, limitations due to cost or other practical considerations, such as security, might result in some inconsistencies.13 These survey data are available publically at www.dhsprogram.com and www.data.unicef.org respectively. Countries were considered eligible for inclusion in this analysis if: (1) a population‐ based survey was conducted during or after 2010, (2) the data was available at the start of our analysis (June 2013) and (3) the survey included the standard question on care seeking for children under‐five with suspected pneumonia (cough and rapid or difficulty breathing due to a problem in the chest) and whether or not the caregiver sought care and from where they sought care during the past two weeks. Questions relating to child’s health are included in the women’s questionnaire in DHS and in the questionnaire for under‐fives in MICS. In DHS, only mothers were interviewed, while in MICS the under‐five questionnaire is administered to either mothers or primary caregivers of children under‐five. The following questions (similar in DHS and MICS) were used for the analysis: 1. Has (NAME) had an illness with a cough at any time in the last 2 weeks? (Yes/ No/ Don’t know) 2. When (NAME) had an illness with a cough, did he/she breathe faster than usual with short, rapid breaths or have difficulty breathing? (Yes/ No/ Don’t know) 3. Was the fast or difficult breathing due to a problem in the chest or to a blocked or runny nose? (Problem in chest only/ Blocked or runny nose only/ Both/ Other (specify)/ Don’t know) 4. Did you seek advice or treatment for the illness from any source? (Yes/ No/ Don’t know) 5. A. Where did you seek advice or treatment? B. Anywhere else? (Various services which fall under the following categories: Public sector, Private sector, Other sources and Other (specify) ) In order to be included in this analysis, the respondent had to answer “yes” to questions 1, 2 and 4, and ‘a problem in the chest’ to question 3. Multiple answers were possible for question 5 (sections A and B).
Method of analysis We used recode manuals and guides from both DHS and MICS prior to analysis and recoding, which was conducted using STATA 12.1. We weighted the data according to sample size by using the samples weight variables (V005 in DHS and chweight in MICS)
36 Care seeking behaviour for children with suspected pneumonia provided in the dataset and explained in dataset guides. In case of missing data, the cases were excluded from the analysis. Data analysis was cross‐checked by an independent researcher. To analyse the rate of care seeking for pneumonia, we first calculated how many children under‐five had suspected pneumonia (cough and rapid or difficulty breathing due to a problem in the chest), and then the percentage of those taken for care. For those taken for care, we then categorised them into health providers, also known as ‘appropriate’ providers (i.e., accredited by that country’s government authorities) or other provider also known as ‘non‐appropriate’ providers (i.e., those not accredited to provide antibiotics). These other providers, for this analysis, include private pharmacies, shops, and traditional healers amongst others, for a more detail see the subsection below ‘categorisation of health care providers and facilities’. In both surveys caregivers can report more than one source of care to which they brought their child with suspected pneumonia during the past two weeks. We calculated frequencies and cross tabulations and performed chi‐square (χ2) tests to identify variables associated with the dependent variable ‘care seeking behaviour from an ‘appropriate’ provider’. To determine the adjusted associations between child and caregiver characteristics and care seeking behaviour, we predefined the following groupings of independent variables: child’s age (grouped as <2 years and 2‐5 years), child’s sex (male, female), residential setting (urban, rural), primary caregiver’s or mother’s education (none, primary, secondary and higher) and household wealth quintile (poorest, poorer, middle, richer and richest), which is a composite measure of a household’s cumulative living standard used by DHS and other surveys in countries that lack reliable data on income and expenditures.14 We selected ‘appropriate’ providers as the dependent variable as they have undertaken formal training and are accredited to provide antibiotics and for that reason, we wanted to assess which factors are associated with seeking care from these providers. We performed a multivariate logistic regression model for the dependent variable in order to examine independence of associations (p≤0.05), with all predefined variables in the model. In addition, we calculated odds ratios (ORs) with corresponding 95% confidence intervals (CIs).
Categorization of health care providers and facilities When we refer to ‘any provider’, this includes all possible care providers (i.e. both ‘appropriate’ and ‘non‐appropriate’ providers). The definition of health providers, also known as ‘appropriate’ providers (and therefore referred to as such throughout this paper), varies among countries. However, this category includes both private and public providers who have undergone formal training and facilities that have received accreditation and are therefore authorized to treat children with signs of ARI, for example: ‐ Hospitals: For all countries this includes private and government hospitals.
37 Chapter 3
‐ Primary health care (PHC) facilities: This category includes both private and public health centres, clinics, dispensaries and posts and in some cases a private doctor or other medical personal, village/ community health workers, mobile (outreach) services as well as health facilities supported by non‐governmental organizations (NGOs). ‐ Unidentified other services: These are other government led facilities; however, they are not specified in the country specific databases. Other providers, also known as ‘non‐appropriate’ providers (and therefore referred to as such throughout this paper): include providers that are neither accredited nor authorized to prescribe antibiotics for children with signs of ARI. This varies by country, for this analysis, it includes private pharmacies, shops, and markets as well as relatives and those practicing traditional medicine or faith healing. It also includes private services which are unidentified in the country specific databases.
RESULTS
Of the ten highest burden countries initially considered for the analysis; six met the predefined inclusion criteria of having a DHS or MICS survey in 2010 or later (with data publically available for analysis) and including the standard indicator on suspected pneumonia and care seeking: Burkina Faso, Democratic Republic of Congo (DRC), Ethiopia, Nigeria, Tanzania and Uganda, see Table 3.1. Together, these six countries account for 297,000 deaths or 53% of childhood pneumonia mortality among children under‐five in sub‐Saharan Africa, and 26% of global childhood pneumonia mortality.15 The remaining four countries were excluded for the following reasons: Angola did not have a survey assessing the indicators of interest available, Kenya did not have a survey in 2010 or later and relevant survey data for Niger and Mali were not available at the time we started our analysis. Table 3.1 shows the under‐five mortality per 1,000 live births based on the latest estimates developed by the UN Inter‐agency Group for Child Mortality Estimates.4 The table also presents characteristics of the surveys in the included countries. Data of 76530 children were available for analysis. Sample sizes per country ranged from 7535 (Uganda) to 25192 (Nigeria).
Care seeking for suspected pneumonia The number of children under‐five included in the survey with suspected pneumonia, as reported by caregivers in the previous 2 weeks preceding the surveys, ranged from 267 in Burkina Faso to 1118 in Uganda in the adjusted country samples. In all countries, except Ethiopia, care was sought for the majority of children with suspected pneumonia.

Figure 3.1 shows the large variation in care seeking patterns for suspected pneumonia found across the six countries, juxtaposed with overall levels of pneumonia mortality. In Tanzania 85% of children with suspected pneumonia were taken to a provider by their caregiver, as opposed to only 30% in Ethiopia.
Figure 3.1 Care seeking for signs of childhood ARI by provider type, and overall level of pneumonia specific child mortality by country Sources: Care seeking data comes from DHS and MICS, mortality data comes from the United Nations Inter‐agency Group for Child Mortality Estimation (2013)
Differences are also seen across the countries in overall levels of care seeking from ‘appropriate’ providers (i.e. health care providers), ranging from 27% in Ethiopia to 79% in Uganda. In both these countries, when people do seek care they most often use ‘appropriate’ providers. Uganda and Tanzania were the only two countries where more than 70% of children were brought to an ‘appropriate’ provider. In Nigeria and DRC, overall care seeking is just over 60%, but care seeking from ‘appropriate’ providers stands at or just below 40%. All six countries present relatively high levels of pneumonia specific mortality. Among only those children for whom care was sought, Table 3.2 shows to which specific type of health care facilities and providers these children were brought. In Ethiopia, Tanzania and Burkina Faso children were most often taken to a primary health care (PHC) facility, which includes health centres, clinics and posts as well as community based and outreach services. Hospitals were also frequently accessed for care in Nigeria and Uganda; in fact, in Uganda children were more likely to be taken to a hospital than a PHC facility. With respect to ‘non‐appropriate’ or other providers, private pharmacies are frequently accessed in DRC, Tanzania and Nigeria (18, 18 and 16% respectively). Traditional practitioners and other providers (e.g. vendors, shops, churches, relatives or friends) are also often consulted in DRC and Nigeria in particular.

Table 3.3 shows the results of the multivariate logistic regression to examine potential associations between child or caregiver characteristics and care seeking behaviour from ‘appropriate’ providers. In Nigeria, the influence of the age of a child, when controlling for the other variables (i.e., sex, urban‐rural residence, education and wealth) shows that younger children (<2 years) were 1.7 times more likely to be brought to a care provider than children between 2 and 5 years of age (95% CI 1.1‐2.5, p<0.01). This significant association between younger age of the child and care seeking from ‘appropriate’ providers was also found for Ethiopia and DRC. In general, the influence of a caregiver’s education, when controlling for other variables shown in Table 3.3 shows that higher educated caregivers and higher wealth quintiles were also associated with higher levels of care seeking from ‘appropriate’ providers in this group of countries. In Uganda having at least a primary education, when controlling for age and sex of the child, urban‐rural residence and wealth, was associated with higher likelihood to seek care. In Tanzania, Ethiopia, Nigeria and Burkina Faso, caregivers from the richest quintile were much more likely as those from the poorest quintile to seek care for their child with suspected pneumonia, after controlling for age and sex of the child, urban‐rural residence and education, with odds ratios ranging from 4.7 (95% CI 1.5‐15.1) to 9.4 (95% CI 2.3‐39.3). Similar patterns did not emerge in the DRC and Uganda. With regard to the sex of a child, controlling for the child’s age, urban‐rural residence, education and wealth, girls were 1.7 times more likely to be brought to seek care in Uganda than boys (95% CI 1.2‐2.4, p<0.05). We found no statistically significant differences in care seeking patterns between rural and urban settings after controlling for the age and sex of a child, education and wealth.

DISCUSSION
We found considerable variation in care seeking behaviour for suspected pneumonia across six high pneumonia mortality countries in sub‐Saharan Africa. The three countries found to have the lowest levels of care seeking from ‘appropriate’ providers (i.e. health facility/ provider) were Ethiopia, Nigeria and DRC.
Overall care seeking Country variations in care seeking for childhood infections, including pneumonia, have been reported previously.16‐17 We concur with the conclusions of the Hodgins study16 that programs should be adjusted to country specific needs based on identified barriers. Our data clearly show that both care seeking from ‘appropriate’ providers and childhood pneumonia mortality is high in Uganda, suggesting that the quality of care available to these children may be sub‐standard or that children present for care late, as has been reported in other studies.18‐20 In Ethiopia, where we found care seeking to be the lowest among the six countries, strategies that investigate what the key challenges are related to accessing care need to be prioritized. Previous studies conducted in Ethiopia indicate that lack of knowledge and delay in recognition of the severity of an illness are important factors that predict care seeking,21‐22 as are religion23 and household wealth.24 Further, vast distances to facilities within the country were the impetus for the health extension worker program, which has made important strides in increasing coverage of treatment for childhood illnesses, although some challenges remain.25 Our analysis confirms that there is a strong association between wealth and care seeking in Ethiopia, which we also found in Tanzania, Nigeria and Burkina Faso. Other studies report that the associations between wealth and care seeking are not only linked to whether care is sought or not, but also from which facility. Studies from Nigeria and Tanzania reported that poorer women are more likely to utilize facilities which provide poor quality services.26‐27 In Tanzania, women living in rural areas tend to visit primary health care (PHC) facilities more often, whereas richer and higher educated women visit hospitals or better equipped health facilities. The main reasons for bypassing PHC facilities are related to the lack of diagnostic aids and drugs.28 In each setting, once solutions to locally specific barriers in care seeking are identified, it will be critical to ensure that demand generation efforts are not jeopardized by sub‐ standard service and treatment availability.29‐30 An earlier study that reported higher treatment rates in countries with well‐established private sector services suggested that the appropriateness of treatments provided may be a challenge.17 Our study also found high use of ‘non‐appropriate’ providers (e.g. private pharmacies, traditional practitioners and other services, such as shops, churches, relatives, etc.) in
44 Care seeking behaviour for children with suspected pneumonia both DRC and Nigeria, 43 and 38% of the total care seeking respectively (see Table 3.2). Another recent study from DRC indicates that while ‘formal care’ (in this paper referred to as health providers or ‘appropriate’ providers) is valued, the cost of services creates barriers and results in families either self‐medicating or using traditional provider options.31 Another study from DRC also concluded that costs were a barrier, but suggested that distrust of government health services is also a problem.32 Similarly, studies of care seeking for childhood illnesses in Nigeria have reported high use of home care, drug vendors and private clinics due to financial constraints, wishing to try home management first, and poor recognition of the severity of the illness or waiting for the child to improve.33‐35 As Quinley & Govindasamy have reported, drug shops do often function as de facto clinics.36 Strategies for improving the quality of care in these service delivery points may be an important program strategy to consider.16 The only association between sex of the child and care seeking we found was in Uganda, where girls were actually more likely to be brought for care than boys. Earlier published findings from Asia indicate preferential care seeking for male children,37‐38 and previous African studies of the association between the sex of a child and care seeking in Tanzania, where no association was found.39,40 In addition, while studies have reported associations between better health outcomes and higher levels of caregiver education,34‐41 for associations between caregiver education and care seeking ‐ hence increasing the likelihood of receiving correct treatment ‐ we only observed an association in Uganda. We found differences between care seeking in rural versus urban areas in Burkina Faso, Ethiopia, Nigeria and Tanzania, as has been reported in previous studies.21,42 For example, in Ethiopia the percentage seeking care from an ‘appropriate’ provider in rural areas is 25, in contrast to 47% in urban areas. However, when we controlled for wealth, education, sex and the age of a child, there was no independent association of urban‐rural residence. This may be (partly) explained by lower education and wealth status of those living in rural areas. In relation to this, our analysis shows that lower wealth quintiles were associated with lower levels of care seeking from ‘appropriate’ providers in Burkina, Ethiopia, Tanzania and Nigeria, independent of the actual residency of caregivers. In other words, the poorest are the least likely to seek care, independent of where they live (i.e. in urban or rural settings). This implies that those living in rural areas are more disadvantaged due to poverty and access to health services. These associations were not found in DRC and Uganda. Our study indicates that care seeking for children under the age of 2 with suspected pneumonia was more frequent than for children between 2‐5 years of age, particularly in Nigeria, Ethiopia and DRC, this relationship was significant. Although similar findings were reported in previous studies from Nairobi43 and Nigeria,44 studies from Uganda19 and Ethiopia24 reported no association between care seeking and age of the child. Seeking treatment for younger children with suspected pneumonia is especially critical
45 Chapter 3 to decrease childhood mortality due to pneumonia, not only because the incidence of pneumonia is highest amongst these children, but also because 81% of child deaths due to pneumonia occur within this age group.45 Demand generation efforts should take this into account and should focus on preventive measures as well, e.g. increasing coverage of immunization, and improving breastfeeding practices and nutritional status.46‐47 One of the strategies to improve the quality of care is through Integrated Management of Childhood Illnesses (IMCI) – a strategy designed to reduce child mortality and morbidity due to common illnesses. IMCI has been implemented in all 6 countries included in these analyses. The strategy aims to improve family and community health practices, case management of health staff and the overall health system,48 although the extent to which this is achieved in any particular setting will vary. The level of implementation, quality of training and supervision will have an impact on care seeking behaviour and the quality of care.49,50 Moreover, the quality of care is not merely affected by the capacity of health workers, but also on the availability of essential resources, inkling appropriate medicines.49 The IMCI protocol guides health workers to classify a child as having pneumonia when s/he presents with a cough and fast and/ or difficult breathing due to a problem in the chest. Despite the protocol, health workers are often challenged to classify and prescribe treatment for these suspected pneumonia cases.19,51
Limitations There are limitations related to these analyses. Pneumonia prevalence, which is collected in household surveys primarily for use as a denominator for indicators relating to pneumonia, should be interpreted with caution as it depends on caregivers’ perception of the signs and symptoms (which may or may not be accurate) and their capacity to recall the events (which may be prone to recall bias), leading to incorrect estimates.52 Moreover, the prevalence of suspected pneumonia varies seasonally, which also influences care seeking (i.e., it may be more difficult to take a child for care during harvest and rainy seasons). In relation to this, caregivers may identify signs and symptoms such as cough and difficulty or rapid breathing due to a problem in the chest, while, clinically these may refer to another acute respiratory tract (ARI) infection, rather than to pneumonia specifically. Secondly, survey data do not allow us to determine the specific pathways of care taken (i.e. which care provider – either ‘appropriate’ or ‘inappropriate’ ‐ was visited first), if the same provider was visited multiple times or if the same health worker assessed a sick child in a health centre and again later in his or her capacity as a private pharmacist. Having this additional information would allow for more nuanced analyses of care seeking behaviours in these settings.
46 Care seeking behaviour for children with suspected pneumonia
Finally, survey data also do not provide information on severity of illness, and it is therefore not possible to distinguish whether or not seeking care from PHC facility was appropriate, or if the child should have gone directly to hospital. In relation to this, it would be interesting to assess if a child received treatment, however, as Hazir et al (2013) concluded ‘…data in its current format from DHS/MICS surveys should not be used for the purpose of monitoring antibiotic treatment rates in children with pneumonia at the present time as their quality is jeopardized’.52 This is because the identified cases depend on the caregiver’s interpretation of signs and symptoms; the validity of receiving antibiotics is therefore dependent on the accuracy of this interpretation.
Further research areas In this analysis we included (when applicable) multiple providers/facilities per child, which could include both ‘appropriate’ and ‘inappropriate’ provider categories. Further research could assess the percentage of care sought from more than one type of provider and why. A better understanding of the complexity of care seeking and associated delays including the timing of care‐seeking could reveal additional information about quality of care and user preferences. Further research should aim to understand the correlation between mortality and care seeking, and assess if there are differences in this association between any care seeking and care seeking from ‘appropriate’ providers. These analyses should focus not merely on pneumonia, but also on the other main causes of illnesses (e.g. diarrhoea and fever).53‐54 Finally, we need to know why overall care seeking is unacceptably low in some countries, even for the youngest children (who benefitted from slightly higher levels of care seeking in this study but who are also the most likely to die from pneumonia). It is critical to identify strategies to improve the quality of services visited most often by caregivers, including the ‘informal’ sector, e.g. private pharmacies.
Conclusion In conclusion, this study illustrates that prior to planning strategies to decrease pneumonia mortality, it is crucial to understand care seeking patterns (and the related determinants) between countries and within countries using available data, such as national survey data. Further research is needed to better understand the reason behind these findings by conducting more systematic analyses at national and sub‐ national level, including the assessment of socioeconomic, knowledge and information, cultural and health system factors that influence care seeking. Locally specific research is also needed to understand why families choose the providers and facilities they choose, and then programmatic strategies should be developed that engage local community members to identify relevant, feasible and acceptable solutions.

ABSTRACT
To decrease child mortality due to common but life threatening illnesses, community health workers (CHWs) are trained to assess, classify and treat sick children. For pneumonia, CHWs are trained to count the respiratory rate of a child with cough and/ or difficulty breathing, and determine whether the child has fast breathing or not based on how the child’s breath count relates to age‐specific respiratory rate cut‐off points. International organisations training CHWs to classify fast breathing realized that many of them faced challenges counting and determining how the respiratory rate relates to age specific cut‐off points. Counting beads were designed to overcome these challenges. This paper presents findings from different studies on the utility of these beads, in conjunction with a timer, as a tool to improve classification of fast breathing. Studies conducted by the International Rescue Committee and Save the Children among illiterate CHWs assessed the effectiveness of counting beads to improve both counting and classifying respiratory rate against age specific cut‐off points. These studies found that the use of counting beads enabled and improved the assessment and classification of fast breathing. However, a Malaria Consortium study found that the use of counting beads decreased the accuracy of counting breaths among literate CHWs. Qualitative findings from these studies and two additional studies by UNICEF suggest that design of the beads is crucial: beads should move comfortably and a separate bead string, with color‐coding, is required for the age‐groups with different cut‐off thresholds – eliminating more complicated calculations. Further research, using standardised protocols and gold standard comparisons, is needed to understand the accuracy of beads in comparison to other tools used for classifying pneumonia, which CHWs benefit most from each different tool (i.e. disaggregating data by levels of literacy and numeracy) and what the impact is on improving appropriate treatment for pneumonia.
54 The use of counting beads to improve the classification of fast breathing
INTRODUCTION
Because of the overall complexity of diagnosis, the still staggering mortality, lack of diagnostic aids and the growing problem of antibiotic resistance for pneumonia, there is an urgent need for more robust data on tools for pneumonia diagnosis. Pneumonia is the leading cause of childhood mortality, accounting for 17% of global deaths of children under five.1 Timely recognition of pneumonia signs and symptoms, appropriate care seeking and access to antibiotic treatment can prevent many of these deaths. The Integrated Management for Childhood Illness (IMCI) protocol for ‘Caring for Newborns and Children in the Community’ guides community health workers (CHWs) to assess fast breathing as an indicator of non‐severe pneumonia in children with cough and/ or difficulty in breathing.2 There are two steps in detecting if a child has fast breathing or not: first, a CHW needs to visually count a child’s breath for one minute, second, the CHW has to determine how the child’s breath count relates to age specific respiratory cut off points.2 International organisations training CHWs with various degrees of literacy and numeracy realized that many of them faced challenges in counting and relating the breath count to age‐specific cut‐off points. However, accurate assessment of fast breathing is crucial as selected children (children 2‐11 months of age with a respiratory rate (RR) of 50 or more breaths per minute and children 12‐59 months of age with a RR of 40 or more) are classified as having pneumonia based on their breathing rate and require immediate treatment with antibiotics.3‐4 Watches and timers have been used as timing aids to facilitate one minute respiratory rate counting. Box 4.1 shows an example of an acute respiratory infection (ARI) timer that is distributed by UNICEF. Until now, there is limited evidence on counting devices and other affordable tools to help CHWs in resource poor settings improve classification of fast breathing. One study evaluating the effectiveness of an abacus with a built‐in sandglass concluded that CHWs were better able to correctly classify fast breathing with the breath counter.5 The potential of the use of counting devices, such as beads, is unknown due to lack of information regarding their effectiveness and utility. However, several organizations (including International Rescue Committee (IRC), Save the Children, Malaria Consortium, UNICEF and Population Services International (PSI)) have conducted small scale studies among CHWs with differing levels of literacy and numeracy, using counting beads, which contribute to the knowledge base. In this review we compile the current evidence‐base of the effectiveness of counting beads to assess and classify breathing rates to guide pneumonia diagnosis. These findings are essential to further guide integrated Community Case Management (iCCM) programing aiming to decrease pneumonia deaths in young children.

The ARI timer makes a ticking sound every second and has an alarm after 30 seconds as well as a final alarm to inform the user that 1 minute has passed. The user must press the button to start the 1 minute timing, during which a child’s breath is counted.
Box 4.1 The ARI timer.
METHODS
The findings presented are based on studies conducted by IRC, Save the Children, Malaria Consortium and UNICEF to improve iCCM programming in South Sudan, Uganda and Ghana. All CHWs in these studies were trained in iCCM using the WHO/UNICEF IMCI ‘Caring for newborns and children in the community’ protocol. CHWs are named differently in the various countries, for example in South Sudan they are called community based distributors; however, in this paper, we refer to them as CHWs.
We compiled all research findings on the use of counting beads within these programs. While most findings presented are part of larger research initiatives, in this review we focused on the following questions: 1. What is known regarding primarily illiterate CHWs’ ability to assess and classify fast breathing without the use of counting beads? 2. Does the use of beads improve the ability of CHWs, particularly those with limited or no literacy and numeracy, to correctly classify fast breathing (hence, including tracking the breaths and classifying the breath count based on IMCI age‐specific respiratory rate cut‐off points)? 3. Does the use of beads improve the ability of literate CHWs to correctly assess the breath count? 4. What are CHWs’ perceptions of these tools, and does this differ by literacy level?
A brief description of the studies is provided below and a summary of the key methodological elements of the different studies can be found in Table 4.1. All studies used the ARI timer explained in Box 4.1 and the design of beads used by the various organizations can be found in Box 4.2. The results are separated by qualitative and quantitative research methods, as well as by organization. In addition, anecdotal evidence from two rapid assessments, from PSI in Democratic Republic of Congo (DRC) and from IRC in Sierra Leone, is not included in the methods or findings, but is used to strengthen the discussion.

Quantitative research
International Rescue Committee study in Uganda and South Sudan As part of a larger assessment evaluating the quality of care provided by CHWs, IRC compared the CHWs’ ability to assess fast breathing using the ARI timer alone versus using the timer and beads. The geographical areas (payams) were selected on the basis of their geographical accessibility to the evaluation team and recent start‐up of the program.
58 The use of counting beads to improve the classification of fast breathing
First, CHWs were asked to describe the cut‐off points for fast breathing for the two age groups (2‐11 and 12‐59 months) and to count the child’s respiratory rate (RR) using the ARI timer. A trained clinician who was part of the evaluation team counted simultaneously with the CHW. The RR from the clinician was written down and the CHW was asked to say his/her count. Afterwards, CHWs were given the right counting bead string for the age of the child being assessed and were shown how to move their fingers along the beads and to stop when the timer beeped. Then CHWs were asked to repeat the assessment with the same child using the timer and the beads. The clinician used the counting beads simultaneously with, but out of sight of, the CHW. The beads were counted back and recorded for both the CHW and the trained clinician. Microsoft Excel was used to analyse the data.
Save the Children study in South Sudan The use of beads by CHWs with limited numeracy was part of an operational research lead by Save the Children. The research was conducted to assess the effectiveness of simulation based training of CHWs using video technology.
During the training, CHWs were shown video clips of cases with danger signs (including case scenarios of malaria, pneumonia and diarrhoea) and the interactions between CHWs and caretakers. The video also showed the assessment, classification, treatment and advice on home care. CHWs were given 1 set (two strings) of beads to count and classify the breath count along with the ARI timer acting as a stop watch. CHWs were taken to a hospital outpatient department for post training skills assessment, where they assessed sick children (40 out of the 69 cases had a history of cough). Each CHW managed (assessing, classifying and deciding to treat) 2‐3 sick children aged 2‐59 months. Each CHW also completed a knowledge questionnaire. As these particular CHWs were illiterate, one clinician trained in IMCI observed the CHWs’ management of sick children and recorded the assessment, classification and treatment findings on a study form. A senior evaluator who was also an IMCI trainer independently assessed the children at the same time and recorded his findings on a similar form. The RR was measured for all 69 children by the CHWs and the evaluator. To assess fast breathing the CHW had to choose the correct bead string for the age group. The observer marked the case as having fast breathing if the CHW reached the red beads (fast breathing for 2‐11 month and 12‐59 month age groups) within the minute. The evaluator used the ARI timer to count the child breaths and noted the actual breath count in the form. The data was entered in CSPro, and imported and analysed in Microsoft Excel.
Malaria Consortium study in Uganda Malaria Consortium assessed if there was a difference in accuracy in counting RR among CHWs using 1) the ARI timer alone versus 2) using the timer & beads and 3) using a mobile phone application, where the centre button on the phone was
59 Chapter 4 pressed for every breath observed, and which beeped after one minute, after which the count was displayed. The sub‐county was selected on the basis of its geographical location and mixture of CHWs with different age, sex and literacy levels (varying from being able to read and write well in any of the local languages (78%) to fairly well (22%)).
First, each CHW received a detailed explanation of how to count the RR, while simultaneously using the ARI timer, the same timer with beads as well as the mobile phone application. The CHWs then had the opportunity to practise the three different methods of counting the RR on videos of children with different breath counts. After familiarizing themselves with the three methods, each CHW was observed counting using the three options respectively, on children with different breath counts. The video case scenarios were displayed on laptop screens, enabling one CHW to assess a child at a time. The final RR was recorded for the three tools as follows: 1) when using the timer alone, the CHW was asked for the final RR count, 2) when using both the timer and beads, the beads were counted back by a research assistant who provided the final RR count, and 3) for the mobile phone application, the result was read from the screen. The breathing rate of the children in the video was known and was used as the gold standard. STATA 12 was used to analyse the data. The research only assessed the impact on counting the RR and did not assess the impact of these devices on classifying the breath count against the age‐specific cut‐off points.
Qualitative research Along with their quantitative research efforts, IRC and Malaria Consortium assessed CHWs’ perceptions about the beads, focussing on their opinions and proposed improvements. Data were collected through interviews. Malaria Consortium also assessed CHWs’ perceptions about how the use of counting beads helped them communicate the test results to caregivers.
Other qualitative research was initiated by UNICEF, as part of a broader effort to identify CHWs’ unmet needs regarding tools to support the assessment and classification of RRs. In Uganda the focus of the research was on CHWs’ experiences assessing RR using the ARI timer and their ideas regarding tools that might be useful to help them improve their assessment and the classification of RRs. The CHWs were not familiar with the use of beads. Building on these findings, a subsequent study was conducted in Northern Ghana, where the CHWs had been trained to use both the ARI timer and beads. The main objective of this study was to help UNICEF improve the design of diagnostic aids based on the challenges CHWs indicated they face while assessing, classifying and identifying treatment needs for children under‐five with rapid breathing.
60 The use of counting beads to improve the classification of fast breathing
FINDINGS
Table 4.2 summarizes the key findings of the various studies. In addition, an overview of the two different types of counting beads (a non‐age specific type and an age‐specific type with color‐coded beads) can be found in Box 4.3.
Box 4.3 Overview of the two types of counting beads intended for use in conjunction with an ARI timer. Non‐age specific counting beads These counting beads are designed to help the CHW keep track of the amount of breaths taken. The CHW counts moves bead for each breath. When one minute has passed the CHW counts back the beads to determine the respiratory rate. Due to the colour‐coding of a number of beads (e.g. every set of 10), the CHW can count back the beads per colour: e.g., 1 colour = 10 breaths, 2 colours = 20 breaths, etc. Based on the respiratory rate the CHW compares the result against the IMCI guideline, correctly remembering the age specific cut‐off rate.
Age‐specific beads with color‐coding These counting beads support the CHW not only with counting, but also with interpreting the RR against the IMCI guidelines. These beads remove the need to count by the CHWs to assess pneumonia (unless the actual RR is required for reporting purposes) because they consist of a set of two strands or rows of beads that are color‐coded to match the thresholds for the two different age groups. Depending on the age of the child, the CHW selects the matching bead strand and moves the beads for one minute. Once the minute has passed, the CHW can identify if the child has pneumonia or not, depending on the colour of the bead s/he is holding between his/ her fingers.
Primarily illiterate CHWs’ ability to count breaths and their knowledge of age‐specific cut‐off rates The IRC assessed what the key challenges were for primarily illiterate CHWs while classifying fast breathing. Findings indicated that 46% (21/46) of CHWs in Uganda were not able to apply the age‐specific cut‐off points and 33% (15/46) made an incorrect count using the ARI timer. In South Sudan, 59% (19/32) of CHWs were not able to apply the age‐specific cut‐off points and 72% (23/32) of CHWs made an incorrect count using the ARI timer.
Primarily illiterate CHWs’ ability to classify fast breathing using counting beads In South Sudan 13% (4 out of 32) of the CHWs were able to classify fast breathing using only the ARI timer, whereas this number increased to 63% (20/32) (OR=11.7, p=0.002) when they used the beads together with the timer. Findings were similar in Uganda, where the ability to classify fast breathing increased from 37% (17/46), using only the timer, to 73% (24/33) (OR= 4.4, p<0.005), using both tools. Combined the data from both countries; the ability to classify fast breathing increased from 27% (21/78) to 68% (44/65) (OR= 5.7, p<0.005), see Figure 4.1.

Save the Children’s research did not have a component of assessing a sick child without the use of beads, as they identified that CHWs had limited numeracy, and were not able to count beyond 10. A total of 69 sick children were assessed by the 27 CHWs. Using the ‘age‐specified and color‐coded’ beads and ARI timer, the CHWs classified 25 cases as suffering from fast breathing. The senior evaluator who only used the ARI timer classified 23 as fast breathers. Of the 25 CHW classified fast breathing cases, 15 (60%) matched with the evaluator classified fast breathing cases.
CHWs were also administered a knowledge questionnaire which included questions on use of beads appropriate for age. All 27 CHWs picked the beads appropriate for the 2 age groups. With respect to classifying a child as having fast breathing, 26 out of 27 picked the right colour (red) for the 2‐11 months group and 27 out of 27 for the 12‐59 months age group.
Literate CHWs’ ability to correctly count breaths using counting beads In Uganda, Malaria Consortium assessed if the use of tools, including counting beads, improved the ability of literate CHWs to count the respiratory rate. CHWs were 5.6 times more likely to count (not classify) respiratory rate correctly (i.e. ±2 breaths) using the timer alone compared to when it is combined with beads (OR=5.6, p<0.001). There was no significant difference between the ARI timer and mobile phone application (OR=1.1, p=0.08), implying that CHWs have a similar capacity to correctly count respiratory rate using either of the assessment methods (i.e. counting themselves versus pressing a button for every breath observed).
Overall, the median difference between the “true rate” and the rate observed with the three methods was ‐1 (IQR ‐5−2) for the UNICEF mer, ‐1 (IQR ‐7−2) for the mobile phone application and ‐5 (‐12−2) for the ARI mer with beads. Using the sign test for non‐parametric data on matched pairs, the differences in rates observed using the ARI timer compared to the true rate was not significantly different from 0 (p=0.01),
63 Chapter 4 whereas for the mobile phone application and counting beads, the difference between the rates observed and the true rate were significantly different from 0 (p=0.001 and p<0.0001, respectively). Using the same test, the median difference observed between the ARI timer and mobile phone application was not significantly different (p=0.179), whereas the difference was significantly different between the ARI timer and the counting beads (p<0.001) as well as between the mobile phone timer and the counting beads and timer (p=0.001).
When analysing the accuracy of the three different methods by the characteristic of the rate of the child in the video (i.e. normal or fast), it was demonstrated that all three methods performed much better on the slower breathing rates (i.e. 40 breaths/min) than the fast rates (i.e. 65 and 66 breaths/min). All three methods tended to overestimate the rate in the slow breathing scenario whereas they all under estimated the rate in the fast breathing scenarios.
CHWs’ perceptions on the use and design of age‐specific and color‐coded beads The color‐coded beads designed by IRC in Uganda match the colour of the locally available amoxicillin packages for specific age groups and according to (mainly illiterate) CHWs this helped them to identify the correct string needed for the child, eliminating the need to recall the cut‐off points for the different age groups. Regarding the use of counting beads, CHWs interviewed by IRC were most likely to say that: 1) the use of beads eliminated the need to count or worry about forgetting the number or making mistakes while counting; 2) it was easy to move hands along the beads; 3) it was easy to know when to give the treatment; and 4) it was easy to explain to the mother that her child did not need medicine. The need for more training and practice regarding the use of the beads in combination with the ARI timer was mentioned by CHWs in South Sudan and Uganda.
In the study amongst literate CHWs by Malaria Consortium in Uganda, CHWs expressed their support for alternative methods to count the RR other than the timer which they were familiar with. Using the beads, in addition to the timer, was perceived as being advantageous because each breath being represented by movement of a bead and then counting of the beads could be done afterwards, thus giving more accurate results.
“What I have liked about this method is that I don’t have to count the beads as I move them, counting usually comes last and this gives me more concentration on observing the child and moving the beads.”
64 The use of counting beads to improve the classification of fast breathing
The method was acknowledged as one that could give a quick picture of the diagnosis by identifying the colour of the bead where the hand has stopped after the alarm has gone off (i.e. whether white or red/green bead), the next steps could follow later:
“From what I have learnt today, the combination of both the timer and beads is very helpful because it helps me to immediately know whether the child has fast breathing by looking at the colour of beads where I have stopped and then, I count the beads to confirm what I have seen, after which I write in my book.”
The use of the beads also made it easier to communicate the results to the caretaker, as the colours visually flagged if the child had a high breath rate (indicating pneumonia) or not.
However, the beads were also perceived by some as disadvantageous because combining the timer and beads was considered to be more tasking, with a slow bead movement process and therefore reduced accuracy. During observations, it was noted that CHWs often found it difficult to start moving the beads immediately after starting the timer.
“For me, I find this method very challenging because I have to observe three things at the same time: I have to look at the child, start the timer and also move the beads at the same time, which is a bit tasking. That is why you have seen that I have been forgetting to put on the timer as I move the beads.”
Related to the design, CHWs often mentioned that the space between individual beads can affect the outcome of the count. The space between the beads should be small, as the bigger the distance was between the beads, the more difficult it was to move them. The CHWs also suggested that the beads should be light and not attractive in order not to be mistaken for accessories and have a strong string, which would not break easily.
Data from the assessment in Uganda by UNICEF, where mainly illiterate CHWs only used the ARI timer, revealed that CHWs would find it useful to have a device that supports them with the classification of fast breathing and that would help them communicate the findings to the caregivers. When the CHWs in Uganda were shown counting beads they mentioned that beads might be confused with a toy; however, it would help them with the assessment and the classification of fast breathing.
“I would have preferred the beads because each time I count, I hold a bead so I will be able to know how many beads I left behind in case I forget where I was when counting”
65 Chapter 4
“Green is OK. Red is for danger.”
CHWs perceptions on the use and design of non‐age specific beads The main concern among mainly illiterate CHWs regarding the use of non‐age specific beads used in the Northern region of Ghana, was that these beads still required counting and remembering the cut off rate. The beads also have ‘separator bead’ which the CHWs thought creates confusion since “we move the beads without looking at them”. Nevertheless, the use of prayer beads in the region is common; CHWs are used to counting with beads and are at ease with this. However, the CHWs reported that this similarity could reduce the acceptance by caretakers as the beads are perceived as a tool for prayer and not as a healthcare related tool.
When shown the ‘age‐specific and color‐coded’ beads used by IRC and Save the Children, the CHWs and their supervisors in Ghana showed a strong preference to this design as it eliminated the need to count and remember the cut‐off rate.
“This one has only two colours and the colours easily tell if the child has pneumonia or not. I think that this one will be more convenient to use than the current one we have.”
DISCUSSION
This review of studies on the utility of counting beads as a tool to improve classification of fast breathing in children with cough and/ or difficulty breathing to guide pneumonia diagnosis, shows that the introduction of ‘age‐specific and color‐coded’ counting beads, in addition to an accurate timer, can help CHWs with limited numeracy and literacy to more accurately assess fast breathing. While CHWs also expressed concerns on the task‐intensity of the method, in general it was acceptable and applicable across different settings.
There are several limitations associated with the studies included in this review. First, the studies used several different research approaches, methods (including gold standards) and research questions. Moreover, programmatic settings differed as well as the levels of literacy and numeracy of the CHWs. Second, the case scenarios by the various organizations assessed children in different settings (at home, hospital or on a video screen) which resulted in different breathings patterns, e.g. the children assessed at home were unlikely to have fast breathing, although a few of them happened to have it. This review suggests that these factors influence the utility of beads.
66 The use of counting beads to improve the classification of fast breathing
Data from IRC, Save the Children and anecdotal evidence from PSI and IRC suggest that ‘age‐specific and color‐coded’ beads enable and improve accuracy in the classification of fast breathing by CHWs with limited literacy and numeracy. However, if literacy and numeracy is not an issue, findings from Malaria Consortium show that the use of beads complicates the assessment, as it resulted in more in‐accurate counts (i.e. CHWs were 5.6 times less likely to count correctly using the beads and timer). A reason for the breathing count inaccuracy by literate CHWs was that some perceived the use of beads as more task‐intensive. While for CHWs with limited literacy and numeracy (e.g. those not able to count beyond 10), the use of beads enabled them to track the breathing rates, as well as classifying the count against the age‐specific cut‐off points, which would not be possible without these beads.
It was also found that the rate of breathing influences the accuracy in the respiratory rate count. The research conducted by Malaria Consortium shows that, regardless of the tool CHWs used, they tended to overestimate the rate in the slow breathing scenario whereas they all under estimated the rate in the fast breathing scenarios.
Recommendations Due to the overall complexity of diagnosis, the still staggering mortality, lack of diagnostic aids and the growing problem of antibiotic resistance for pneumonia, there is an urgent need for more robust data on tools for pneumonia diagnosis. Regarding the use of counting beads, these data show that it is premature to conclude to which degree the beads, in addition to a timer, would improve the ability of trained CHWs to correctly classify fast breathing. A more conclusive assessment is needed amongst sick children, disaggregating data by intensity of training and supervision, levels of literacy, numeracy and comparing the final breath count to a gold standard. Previously conducted studies on pneumonia diagnosis by CHWs indicate that even if CHWs are good in counting, they still often make mistakes in classifying the breath count.6‐7 Here, the use of beads could help in classification and it should become clearer how for literate CHWs this potential positive effect is affected by the inaccuracy in counting when using beads. Is this because of the lack of familiarity in using the beads, or is the use of beads actually more complex and task‐intensive? Concurrent to the need of more evidence regarding the utility of beads, there is a need for more research assessing the effectiveness of other devices, such as automated respiratory rate counters.
Conclusion Given the overall paucity of data, this review of recent studies provides insights on a range of issues to consider when implementing counting beads in iCCM programs. This emerging evidence suggests that the introduction of well‐designed ‘age‐specific and
67 Chapter 4 color‐coded’ beads in addition to an accurate timer can help CHWs who have difficulty counting breaths and remembering age‐specific cut‐off rates to more accurately assess and classify fast breathing. It also has potential to improve communication with the child’s caretakers – particularly regarding appropriate treatment options. However, more research is needed on these and other devices to decrease the inaccuracy in pneumonia diagnosis.

ABSTRACT
OBJECTIVE: To analyse, on the basis of the literature, the potential of mobile phones to improve maternal health services in Low and Middle Income Countries (LMIC). METHODS: Wide search for scientific and grey literature using various terms linked to: maternal health, mobile telecommunication and LMIC. Applications requiring an internet connection were excluded as this is not widely available in LMIC yet. RESULTS: Few projects exist in this field and little evidence is available as yet on the impact of mobile phones on the quality of maternal health services. Projects focus mainly on the delay in recognizing the need and making the decision to seek care, and the delay in arriving at the health facility. This is achieved by connecting lesser trained health workers to specialists, and the coordination of referrals. Ongoing projects focus on empowering women to seek health care. DISCUSSION: There is broad agreement that access to communication is one of several essential components to improve maternal health services and hence the use of mobile phones has much potential. However, there is a need for robust evidence on constraints and impacts, especially when financial and human resources will be invested. Concurrently, other ways in which mobile phones can be used to benefit maternal health services need to be further explored, taking into consideration privacy and confidentiality.
74 Improvement of maternal health services through the use of mobile phones
INTRODUCTION
Progress in achieving Millennium Development Goal (MDG) 5, to improve maternal health by reducing maternal mortality and improving access to reproductive health, is lagging behind the targets. New impulses are needed to attain the goals. Two recent international initiatives recommend mobile phones as a means to improve maternal health services.1‐2
Maternal health Every 90 seconds a woman dies of complications related to pregnancy and childbirth, resulting in more than 340 000 maternal deaths a year.3 Millions of women suffer from pregnancy‐related illnesses or experience other severe consequences such as infertility, fistula and incontinence.4 Delay is considered the key factor leading to women not accessing health services. There are three phases of delay: (i) recognizing the need for health care and in the decision‐making process; (ii) arrival at a health facility; and (iii) receiving appropriate and adequate care at the health facility.5 Underlying determinants that cause the delays are the position of women in society, large geographical distances, weak health systems, poverty and lack of education.4,6
Mobile phones MDG 8 addresses the need to make benefits of new technologies available, especially those related to information and communication. The fastest growing new technology worldwide is the mobile phone. In Africa and Asia, where the burden of maternal mortality is greatest,7 the expectations are that by 2012, 50% of the people will have access to a mobile phone.8 The uptake of mobile phones varies; it is inversely proportional to poverty rates, but also influenced by the competitiveness and thus the price levels of the relevant markets.9 The use of mobile phones in health systems is called mHealth. This article discusses the potential of mobile phones to improve maternal health services in LMIC by strengthening communication throughout different levels of the health system.
METHODS
Our literature search limited to English publications combined terms linked to: maternal health, mobile telecommunication, and LMIC. Only publications considering the basic use of mobile devices (without requiring internet access) were included, as poor internet coverage, high illiteracy rates and low levels of experience in using technology make more advanced use of mobile technology difficult in LMIC.
75 Chapter 5
Searches initiated in PubMed, Embase, Cochrane Library, Scopus, Science Direct and African Journals Online retrieved a large amount of mHealth‐related publications, of which only eight were relevant; these articles address maternal health services in LMIC, the use of mobile devices and reported preliminary results. The search was subsequently expanded to grey literature, and reference lists were also screened for further relevant sources.
LITERATURE FINDINGS
A recently published paper on mobile phone technology for health care in LMIC10 reviewed literature on mHealth, such as treatment compliance, data collection and disease prevention. The authors see great potential for mHealth; however, there is not much evidence of actual and wide‐scale impacts yet. We analysed resources for the particular area of maternal mHealth and confirmed a lack of evidence‐based studies focusing on the efficacy and effectiveness of interventions. Most documentation referred to pilot studies and often lacked baseline data, a control group and clear outcome indicators.
Accessing emergency obstetric care Before the wider use of mobile phones, several project publications considered improved communication through radio systems as one component among several aimed at improving access to emergency obstetric care and referral systems. These projects mainly focused on reducing the second phase of delay. Traditional Birth Attendants (TBAs) and ⁄ or midwives were equipped with walkie‐talkies, enabling them to contact supervisors and ambulances when facing difficult situations. Concurrently, other components such as the overall quality of the health services were improved through more reliable transport means, increased capacity, medical equipment and reduction of financial barriers. Projects in Mali, Uganda, Malawi, Sierra Leone and Ghana, which implemented the above mentioned components, noted a significant reduction in maternal deaths and an increase in supervised births when comparing the situation before and after the interventions. Faster modes of communication and transport were named as important factors in improving access to emergency obstetric care.11‐16 The projects in Uganda and Ghana additionally considered the first phase of delay by connecting traditional health providers to the biomedical health system. As TBAs are frequently at the homes of pregnant women, they can speed up the process there. Krasovec (2004) concluded that studies provided only weak empirical evidence regarding the actual impact of communication systems and that access to tools of communication is not the solution for decreasing maternal deaths in isolated areas.17
76 Improvement of maternal health services through the use of mobile phones
The tight timeframe in which a woman requires emergency obstetric care (due to e.g. severe bleeding) implies that quality services need to be accessible at short notice and supported by effective infrastructure management. In a more recent review, Lee et al. (2009) confirm the need for more rigorous assessments.18 Information regarding plans for scaling‐up projects that use radio systems was only found for the pilot project in Uganda. These plans were not realized due to high costs, inability to maintain equipment and lack of integration into the health system. However, in this project the radio system was later replaced by mobile phones, which were found to be a cheaper and a more practical solution.19
Improving the capacity of lesser trained health workers More recent projects introduced mobile phones to improve the capacity of lesser trained health workers by connecting them to better trained medical staff, thus aiming to reduce the third phase of delay. In Indonesia, Chib et al. (2008) selected 15 health facilities through random sampling; midwives in eight of the facilities received a mobile phone.20 Perceived benefits reported were that: (i) mobile phones made it easier to contact patients, midwives and supervisors, (ii) time efficiency increased due to the ability to coordinate visits, and (iii) if complications occurred assistance was only a call away. Despite these advantages, constraints included the costs, poor mobile phone network infrastructure in rural areas, increased demand for consultation, difficulties in uptake of higher technology programmes for data analysis, and hesitation in contacting supervisors due to organizational hierarchy.20‐21 A recently launched project in Rwanda went a step further by using text messaging to facilitate and coordinate the communication as well as data exchange between community health workers, health centres and hospitals. Preliminary data suggested a positive effect on access to maternal health services and consequently lower death rates.22 An initiative in Tanzania designed a phone‐based application that contained forms and protocols meant to support pregnant women before, during and after delivery.23 The results of a pilot project seemed positive; however, the authors mentioned the need to further assess the impact of the project.
Empowering women to contact health services and access information To decrease the first phase of delay, several programmes aimed to empower women to contact health services and access information; however, data was still being processed at the time this article was written. In Zanzibar, a study following 2,500 women investigated the impact of both voice and text messages on maternal health.24‐25 Text messages were sent to pregnant women containing basic health education and reminders for routine health care appointments. Expectant mothers received vouchers
77 Chapter 5 and phone numbers that they could use to contact services for questions and emergencies. The study assessed the impact on quality of services, health seeking behaviour and maternal morbidity and mortality. The data was being processed at the time of writing this article; the study promised to yield useful information.26 MoTECH is an ongoing project in Ghana aiming to determine how mobile phones can best be used to increase the quantity and quality of antenatal care.27 Results from randomized treatment and control groups were not yet available.28
Gender discrepancies in access to and use of the technology The analysis of the potential of mobile phones for maternal health requires examining how mobile phones may relate to the root cause of poor maternal health, namely the position of women in society.4 Globally, a woman is 21% less likely to own a mobile phone than a man.29 This discrepancy in the uptake of mobile phones is highest in South Asia, followed by Sub‐Saharan Africa. Women who do have access to a mobile phone often use it for business, banking and employment opportunities29‐31 and thus to make themselves more independent. Several projects use mobile phones to improve access to basic education for women, for example text message‐based literacy programmes.29 The main reason for not owning a mobile phone lies in the associated costs, illiteracy and lack of electricity.29,31 Being practical, especially women in Africa are likely to borrow a phone if they do not own one.30 Other discrepancies in the ownership of mobile phones exist between countries and in rural areas versus urban areas, mainly due to poor network coverage.32
DISCUSSION
Robust studies providing evidence on the impact of introducing mobile phones to improve the quality or increase the use of maternal health services are lacking. However, there is broad agreement that access to communication is an essential component of improving the use and quality of maternal health services. The mobile phone has a high potential as it is small, portable, widely used, relatively cheap and the extending network coverage increasingly enables communication with rural and isolated areas. The extremely quick uptake of mobile phones worldwide can shorten delays in seeking and receiving health care. The available literature suggests great potential in connecting traditional and biomedical health care, as well as connecting the different levels within a health care system, provided that women are not restricted due to their position in society, lack of finance or means of transport.
78 Improvement of maternal health services through the use of mobile phones
To fully realize the benefits of mobile communication, research needs to generate the evidence‐basis for scaling up mHealth and enabling informed mHealth policy‐making, and to analyse its benefit in ensuring timely delivery of medical equipment, provide health education and improve access to reproductive health services, e.g. for family planning. So far, projects mainly focus on acute, life threatening situations, but mobile phones can also be used to deliver mass health messages to pregnant women, recalling women with risk factors to present themselves at an antenatal clinic or referring women who suffer from complications such as fistula, incontinence and infertility. Possibilities related to connecting them to specialized hospitals need to be integrated into research and project designs. In addition, all the different applications, best practices, constraints and lessons learned need to be documented. The quick uptake of the mobile phone and its use in health care requires policies and guidance of governments, especially related to issues such as privacy and confidentiality. An overuse of text messaging by the private and public sector will soon be regarded as spam, making it lose its effectiveness. In addition to privacy, governments need to ensure confidentiality of sensitive information.

ABSTRACT
The aim of this paper was to investigate the impact of a toll‐free hotline and mobile messaging service on care‐seeking behaviours. Due to the low uptake of the services, the treatment on the treated estimate is used. For maternal health, the intervention had a strong, positive impact on antenatal care initiation and skilled birth attendance. No effect was observed for postnatal check‐ups, receiving the recommended four antenatal care visits and vitamin A uptake. A negative effect was observed on tetanus toxoid coverage. For child health, no change was seen in child immunization, and a significant decrease was observed for care‐seeking for children with fever. Different factors are associated with care‐seeking, which may explain in part the variations seen across care‐seeking behaviours and possible influence of exogenous factors. Introduction of mHealth services for demand generation require attention to local health systems to ensure adequate supply and quality are available.
84 Improving care‐seeking for facility‐based health services
INTRODUCTION
In Malawi, despite a consistent reduction over the last two decades, infant and under‐ five mortality rates remain high.1,2 Under‐five mortality in Malawi was 71 per 1,000 live births in 2012, down from 112 in 2010 and 234 in 1992.2 Maternal mortality on the other hand dropped only minimally, with the Millennium Development Goal target still about six times lower than the current level of around 675 maternal deaths per 100,000 live births.3‐5 While a package of effective, health facility and community‐based, interventions could significantly improve maternal and child health (MCH) outcomes, uptake of these services remains low.6 For example, less than half of pregnant women in Malawi receive the four recommended antenatal care (ANC) visits and only 12% of women attend ANC within the first trimester of pregnancy. Also, nearly 30% of deliveries are not attended by a skilled birth attendant (SBA) and almost half of women do not receive postnatal care (PNC). And, nearly one third of children with symptoms of malaria or acute respiratory infections (ARI) are not taken to a health facility for advice or treatment.1 To accelerate progress towards improved MCH outcomes, global commitments and national efforts triggered the implementation of new strategies and innovative solutions in low‐resource contexts.7 One such strategy is the use of mobile phones to improve the delivery of health services, also referred to as mHealth. As mobile phone ownership in low‐ and middle‐income countries has grown substantially in the last decade, its potential to improve health services by enabling faster modes of communication is widely recognized.8‐9 Use of mobile phones – for example through two‐way communication, voice messages and/or short message services (SMS) – can overcome persistent health system constraints across the continuum of care.10 In low‐ resource settings, mHealth interventions targeting groups in the general population have shown the potential to improve adherence to treatment protocols, promote healthy behaviour, increase utilization of health services, and increase access to health information.11‐13 To adopt mHealth strategies to increase the utilization of facility‐based services requires measuring and understanding health‐seeking behaviour, while also acknowledging the challenges and shortcomings of health care delivery in resource‐ limited settings.14 Appropriate utilization of facility‐based MCH services is not only linked to demand‐side barriers, such as lack of knowledge and cost of those services, but also to supply‐side barriers such as human resources and availability of medicines.15 For example, care may be sought but appropriate treatment may not be provided.16 In Malawi, among other barriers, challenges linked to accessing services include long distances to facilities, poor perceptions of quality, and lack of human resources.17‐18 Moreover, women and caregivers of young children lack access to health information for decision‐making which leads to delays in seeking care.19‐20

Previous studies have highlighted ways in which mHealth and health promotion can be successful in improving healthy behaviours, positively influencing timely care‐ seeking.21‐22 Strategies such as SMS to deliver health‐related messages23 and hotline systems to enable two‐way communication between individuals and health workers have helped overcome some of the challenges surrounding utilization of health facility‐ based services.24‐25 More specifically for Malawi, mHealth solutions have been limited largely to strengthening provider‐to‐provider communications and data reporting. In two districts in Malawi, an intervention aimed at connecting community health workers and district level officials found that mHealth can aid in dissemination of new information down to the health worker level, improve reporting on service delivery data, and save time and money on transportation costs.26 Another study in Malawi reported on a mHealth pilot project designed to facilitate communications between community health workers and their supervisors through SMS. This study demonstrated that the SMS project improved communication systems for several common applications such as reporting patient adherence, queries to supervisors on complicated symptoms or other issues, requests for medicines, and emergency transport referrals.27 MHealth services to share information between the health worker or health system and the individual have only been documented, yet not studied extensively in Malawi.14 Despite its potential, recent reviews of mHealth projects in low‐resource settings highlight poor evaluations for desired outcomes and impact of these projects,21,28‐30 which includes effects on care‐seeking behaviours. This paper analyzes data from a study using a pre‐post‐test design with a comparison group to examine changes in care‐seeking behaviours among women and caregivers of young children after the implementation of an mHealth initiative. We investigate the impact of the intervention on facility‐based care‐seeking for MCH. These findings are important to further guide the integration of mobile technology into health services. The paper is part of a series analyzing the effectiveness of a hotline and text messaging service named Chipatala Cha Pa Foni (CCPF) or “health centre by phone”, implemented between 2011 and 2013 in the catchment areas of four health centre’s in Balaka district, Malawi. The purpose of these services was to inform women and caregivers on essential care and encourage appropriate care‐seeking during pregnancy, childbirth and infancy.
DATA AND METHODS
Data This paper draws on the evaluation data of the CCPF project in Balaka district, Malawi. The project aimed to increase knowledge and behaviour relating to recommended MCH home‐based and facility‐based care. The CCPF project included a toll‐free hotline
86 Improving care‐seeking for facility‐based health services service providing protocol‐based health information, advice and referrals. Users could access this service to seek advice and information regarding the illness of their child under the age of five. The project also included an automated and personalized tips & reminders mobile messaging service, for which subscribers could opt‐in, with a choice of two local languages. For those community members who did not have a mobile telephone, volunteers were selected from communities and provided with a mobile telephone as a way to provide access to them. Box 6.1 provides some examples of automated tips & reminders messages sent to CCPF subscribers, which include women who signed up and received messages via a volunteer equipped with a phone for community use. The project was implemented between July 2011 and June 2013 in Balaka district, an area with some of the poorest MCH indicators in the country.23 The project is described in more detail in the second paper in this series by Larsen Cooper et al, under review.31 The evaluation used a quasi‐experimental design, with catchment areas of two health centre’s in the contiguous Ntcheu district as the control site. The control district was selected based on similar characteristics with the intervention site and since other districts either had dissimilar characteristics or had other MCH projects ongoing that may influence responses of participants. Once the health centre’s in the intervention and control sites were selected for the study, GIS information was used to map catchment areas of the health facilities and create a comprehensive list of villages in each of the catchment area. GIS information also provided mean distance from each village to the nearest health center.32 The core of the evaluation data consisted of cross‐sectional baseline and end line household surveys conducted in June‐July 2011 and April‐May 2013, respectively. Three questionnaires (household, woman and under‐five) were developed, covering more than 30 MCH indicators largely drawn from the Multiple Indicators Cluster Survey (MICS).32 As it is the rule, the same questionnaires were used at both baseline and end line, with the exception of an additional exposure module administered at end line only with questions referring the CCPF project which began after baseline data was collected. At baseline, a total of 2,840 women (1,119 in the control site and 1,721 in the intervention site) and 3,605 children under‐five (1,385 in the control and 2,220 in the intervention) were surveyed. At end line, a total of 3,853 women (2,509 in the intervention) and 3,261 children were surveyed. Based on the population size in the catchment area, it was determined during planning for the baseline that for statistical significance a minimum of 1,600 subjects was needed per group for the intervention area and a minimum of 1,200 per group for the control.

Messages for pregnant women 6 weeks: “When you and your family know that you are pregnant, a visit to ANC will help you understand everything you need to do to keep the baby healthy.” 10 weeks: “The ANC is your partner in the pregnancy. It is important to go to all 4 of your visits to use the tablets that they have given to you.” 20 weeks: “At ANC visits, you will have a Tetanus Toxoid (TT) vaccine during pregnancy, to stop you or your baby from getting tetanus, which is a serious infection.” 32 weeks: “When you deliver at the hospital, the baby will get everything he needs to start life healthy. Make sure you have a plan to get to the hospital when it is time” “Baby can come anytime now. Do you have all you need for delivery packed in a bag? Pack napkins, cloths, baby soap, towels, basin and clothes for you.” 41 weeks: “Be sure to take your baby to the health centre 6 weeks after delivery. Your baby will get checked and receive more immunizations.”
Messages for mothers for their infant 1 week: “Make sure your baby has its vaccination. In the first week, your baby should get polio vaccine by mouth and the BCG vaccine against TB by injection.” 6 weeks: “This week your baby needs to receive 2 vaccines; OPV and DTP‐HepB‐Hib. She will receive these vaccines 2 more times. It very important to protect your baby.” 11 weeks: “Remember to have your baby sleep under a treated mosquito net every night to prevent malaria and take him to the clinic straight away if he has fever.” 14 weeks: “It is now time for the third and final dose of OPV and DTP‐HepB‐Hib vaccines for your baby. It is important that these are given 4 weeks apart.” 17 weeks: “Prevent pneumonia by protecting your baby from breathing smoke from rubbish or cooking fires and tobacco. Get treatment immediately if baby has fast breathing”
Variables of interest In this paper, we analyze the following aggregate and individual variables related to facility‐based care for MCH: . Facility‐based maternal health care (for women who had a live birth in the last 18 months) ‐ Received the correct dosage of the tetanus toxoid (TT) vaccine during the last pregnancy ‐ Received a Vitamin A dose during the last pregnancy ‐ Received the recommended four antenatal care (ANC) consultations during the last pregnancy ‐ Started ANC in first trimester during the last pregnancy ‐ Gave the last birth under the supervision of a skilled birth attendant ‐ Received one postnatal care (PNC) check‐up within 2 days of the last birth . Facility‐based child health care ‐ Child was fully immunized by first birthday (children aged 12‐23 months) ‐ Child with symptoms of acute respiratory illness (ARI) in the last two weeks preceding the survey sought care at facility
88 Improving care‐seeking for facility‐based health services
‐ Child with fever in the last two weeks preceding the survey sought care at facility The control variables included well known confounders at the community, household, woman and child levels, the selection of which was guided by literature reviews. These variables, as can be seen in Tables 6.1 and 6.2, include at the household level, wealth status, number of under‐five children, and ethnicity and religion of the head of household. At the woman level, these are age, marital status, education, and access to a personal phone. Child characteristics are age and sex. Finally, at the community (village) level, the analyses control for the mean distance to the nearest health centre.
