Midwives were weekly deployed from governmental 21 22 hospitals to provide ante- and postnatal-care in rural clinics. We studied the intervention`s 23 impact on utilization and quality indicators of maternal services after two years’ experience. 24 25 Design: A non-randomized, intervention design was chosen. The study was based on registry 26 27 data only available at cluster level, two years before (2011 & 2012) and two ears after (2014 28 & 2015) the intervention. 29 30 Setting: A total of 53 primary health care clinics in and Jericho regions were stratified 31 for inclusion. 32 http://bmjopen.bmj.com/ 33 Primary and secondary outcomes: Primary outcome was number of antenatal visits. 34 35 Important secondary outcomes were number of referrals to specialist care and number of 36 postnatal home-visits. Differences in changes within the two groups before and after the 37 38 intervention were compared by using mixed effect models. 39 Results: 14 intervention-clinics, and 25 control-clinics were included in the study. Number of 40 on September 29, 2021 by guest. Protected copyright. 41 antenatal visits increased by 1.16 per woman in the intervention-clinics while it declined by 42 43 0.39 in the control-clinics, giving a significant difference in change of 1.55 visits [95% CI 44 0.90 – 2.21]. A significant difference rate in number of referrals was observed between the 45 46 groups 3.65 [2.78 – 4.78] as number of referrals increased by a rate ratio of 3.87 in the 47 48 intervention group while in the control the change-ratio was only 1.06. 49 Home-visits increased substantially in the intervention group, but decreased in control group 50 51 giving a difference RR 97.65 (45.20 - 210.96) 52 Conclusion: The Palestinian midwifery-led continuity model improved utilization and some 53 54 quality indicators of maternal services. More research should be done to investigate if the 55 56 model had effect on individual health outcomes and satisfaction of care. 57 58 1 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 2 of 20 BMJ Open: first published as 10.1136/bmjopen-2017-019568 on 22 March 2018.

In 2013, the Palestinian Ministry of 25 Health, registered 61 405 births and a fertility rate of 4.0 per woman on the West Bank.2 26 27 Maternal health services were provided by the Palestinian government and private, and non- 28 29 governmental organisations. Less than 1% of the women gave birth at home. Governmental 30 facilities covered 45.6% of antenatal-care in 2013. The Palestinian Multiple Indicator Cluster 31 32 Survey from 2014 found that 66.4% of rural women gave birth in governmental hospitals. Of http://bmjopen.bmj.com/ 33 34 them 40.7% left hospital within 6 hours postpartum and 73% did not receive any additional 35 postnatal-care.3 36 37 In 2009 the Palestinian governmental maternal services were described as of poor quality, 38 overcrowded, understaffed, including short antenatal visits lacking content, and dissatisfaction 39 40 4 5

Rural women depend more on governmental facilities than women in urban areas, as 51 private services are scarce.10 52 53 Several studies describe how midwifery-led continuity models improved health for mothers 54 11-16 55 and babies.

1 2 17 3 improve quality in low- and middle-income countries. Two main ways of organizing such 4 models are described in the literature. In the case-load model one midwife cares for up to 40 5 6 women and facilitate relational continuity, while in the team-midwifery model a group of 4-6 7 8 midwives can provide care for up to 360 women through pregnancy, birth and postnatally. 9 Ideally, in both models, women are cared for during birth by a known midwife.11,17 10 11 To improve services in rural areas, the Palestinian Ministry of Health in cooperation with the 12 non-governmental humanitarian organization Norwegian Aid Committee (NORWAC), 13 14 launched implementation of a modified midwifery-led continuity, case-load-model, in 2013, 15 16 starting in NablusFor and Jericho peer Governmental review hospitals and surrounding only villages. The 17 implementation engaged several levels in the ministry of health and the involved 18 19 communities, to overcome known barriers to quality of care.18 20 21 The aim of this study was to investigate whether the Palestinian midwifery-led continuity 22 model had impact on the utilization of services and selected quality indicators at the two 23 24 regions` clinics after two years of experience. 25 26 27 METHODS 28 29 Implementation of the Palestinian Midwifery-led continuity model 30 The modified case-load model aimed at establishing relation between the pregnant woman 31 32 and a midwife during pregnancy and in the postnatal period. http://bmjopen.bmj.com/ 33 34 Assigned, trained and supportive supervised midwives from the local governmental hospital 35 provided ante-and postnatal care in governmental village-clinics and private homes, 36 37 respectively. The same midwife visited the same village weekly, and worked in the labour 38 ward the rest of the week. The midwives used designated cars to facilitate transportation. 39 40 Standard care in the clinics without this model was offered mainly from nurses or midwives on September 29, 2021 by guest.

Clinics where the model was implemented were 51 compared with clinics where the model was not implemented.

1 2 3 The study was part of an implementation research project aiming at documenting the effect of 4 the midwifery-led continuity model. The study was approved by the Regional ethical 5 6 committee of South East Norway and by the Palestinian Ministry of Health. 7 8 9 Clusters 10 11 The clusters consisted of governmental primary health village-clinics in Nablus and Jericho 12 regions. There were 53 active clinics during the study period. During autumn 2013, the 13 14 midwifery model had been implemented in 16 clinics. 15 16 All clinics were Forstratified bypeer rural and urban review location, activity only period and intervention period. 17 18 19 Exclusion criteria 20 21 Clinics located less than three km from Nablus and Jericho centre were defined as urban, thus 22 pregnant women had better access to private and non-governmental services. Clinics in urban 23 24 areas were therefor excluded. Clinics opened during the study period were excluded due to 25 incomplete data. 26 27 Clinics where the intervention was prematurely terminated or introduced later, during the 28 29 study period were excluded because of contaminated data. 30 31 32 Outcomes http://bmjopen.bmj.com/ 33 34 The number of antenatal visits was chosen as primary outcome. Secondary outcomes were 35 number of pregnant women referred to higher level of care, and number of women receiving 36 37 postnatal home-visits. Other outcomes were number of women registered at the clinic for 38 antenatal-care, number of pregnant referred for abnormal blood sugar levels, number of 39 40 women seen by doctor after birth, number of newborn seen by doctor after birth and number on September 29, 2021 by guest.

The registry consisted of 48 anonymous recordings reported monthly from all clinics to the central statistical database in 49 50 the Ministry of Health. The registry did not include data at an individual level. 51 Mean, standard deviation and range were given for normally distributed and count variables. 52 53 Percentage and total number were given for categorical variables. 54 55 56 57 58 4 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 5 of 20 BMJ Open BMJ Open: first published as 10.1136/bmjopen-2017-019568 on 22 March 2018.

1 2 3 Change from baseline in the intervention and standard care groups, and any differences 4 between the groups changes, were examined by using mixed effects linear regression and 5 6 mixed effects Poisson regression. In the mixed models, the clinic was specified as cluster (i.e. 7 8 random variable), time and group, and interaction between time and group were treated as 9 fixed variables. 10 11 The outcome variables were divided by the number of registered pregnant women or newborn 12 to calculate average values, and were then fitted by mixed effects linear regression. Since the 13 14 computed averages are based on different numbers of pregnant women, the model must 15 16 consider the resultingFor heteroscedasticity. peer reviewThis was done by computingonly variance weights for 17 each average before analysis, and including it in a variance formula in the model. 18 19 Additionally, an offset variable was used to adjust for the total number of (individual) 20 21 registrations that were under risk in the mixed effects Poisson regression. 22 23 24 Covariates like population size, employed community midwife and laboratory equipment at 25 the clinic, check points, and distance from hospital, which may have had impact on the study 26 27 groups, were also included in the model for adjusting (table 1). 28 29 Table 1 Characteristics of clusters* 30 Characteristics Intervention Control 31 Population served mean 3402 4636 32

1 2 3 4 5 6 7 8 Postnatal service 9 Postnatal home-visits increased substantially at the intervention-clinics, while at the control- 10 11 clinics it dropped giving a rate difference of 97.65 [45.20 – 210.96], p<0.0001. 12 Women in the intervention group increased significantly mean number of postnatal contacts 13 14 with health services, while no increase was observed at clinics with standard care, giving a 15 16 rate difference ofFor 0. 60 (95% peer CI 0.46 - 0.75) review P<0.0001. Also, only a significant increase in mean 17 number of newborn`s healthcare-contacts were observed with the new model, while not in 18 19 group with standard care giving a rate difference of 0.33 (0.16 - 0.52) p=0.0004. 20 21 22 23 24 DISCUSSION 25 In the clinics with the midwifery-led continuity intervention a significant rise in mean number 26 27 of antenatal visits per woman was observed, whereas number of visits per woman decreased 28 29 in the clinics with standard care during the same period. It is thus likely that the improved 30 utilization was a result of the intervention. WHO recommended in 2002 a minimum of four 31 32 focused antenatal visits for healthy pregnant women.19 After evaluating new evidence, the http://bmjopen.bmj.com/ 33 34 recommendation was revised in 2016 to a minimum of eight antenatal visits to reduce 35 perinatal mortality and improve women’s satisfaction.17,18,20 The women’s increased 36 37 adherence to service in clinics with midwifery-led continuity indicates that women 38 experienced improved quality of the services. Relational continuity is an important tool to 39 40 enhance communication and thus satisfaction of care.16 The association between improved on September 29, 2021 by guest. Protected copyright. 41 42 quality of care and increased utilization is supported by several previous studies and by WHO 43 recommendations to improve utilization and quality by introducing midwife-led continuity of 44 45 care.12,14,17,18 46 47 It is likely that the pregnant woman felt safe knowing that the midwife following her 48 throughout pregnancy also worked at the public hospital where she would give birth, and that 49 50 her midwife would visit her at home after birth. Due to the heavy workload, the midwives 51 could not always be on call to attend birth. Midwifery-led continuity of care in settings with 52 53 few midwife resources and heavy workload must balance the demands on the midwives. 54 55 Although women were not guaranteed that the same midwife providing them ante- and 56 postnatal care would attend their birth, their midwife`s connection to the governmental 57 58 9 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 10 of 20 BMJ Open: first published as 10.1136/bmjopen-2017-019568 on 22 March 2018.

1 2 3 hospital might have reduced the alien barrier to the hospital, and restored feeling of security 4 for the rural women. 5 6 A qualitative study investigated midwives’ experience from working in a similar model in 7 8 Ramallah region from 2007 to 2011. The midwives described how the model enabled them to 9 give individualized care and how the broader scope of practice and increased autonomy gave 10 21 11 them important experience and tools to help. This can explain women adherence to service, 12 because building relationship with competent, respectful and motivated midwives probably 13 14 increased their wish to return to receive more care. 15 16 For peer review only 17 In the intervention group a change in referral mechanisms was observed. The midwives 18 19 working in the new model identified significantly more risk factors causing referral to higher 20 21 level of care, than in clinics with standard care. The identification of more women with 22 abnormal blood sugar level indicates that the model led to identification of important risk 23 24 factors. The proportion of pregnant women referred to higher level of care increased to 25.6% 25 with the new model vs. 13% with standard care during the study period. The proportion in the 26 27 new model is in line with the WHO-estimate presented in guidelines from 2001, that in 28 29 general 25% of pregnant women would need additional antenatal-care due to health 30 complications before or during pregnancy.22 The village clinics had little, if any, technical 31 32 resources to investigate risk signs, so referral to higher level of care was necessary to follow http://bmjopen.bmj.com/ 33 34 up any possible complications. 35 One important quality indicator of antenatal-care is the ability to detect possible 36 37 complications and involve specialist care when necessary. Kearns et al previously 38 demonstrated that improved referral networks was a key element for improving quality in 39 40 low-resource settings.23 The process of information and referral within the system is also on September 29, 2021 by guest. Protected copyright. 41 24,25 42 highlighted by the WHO framework as one core indicator of quality of services. Some 43 countries have much higher potential health risks than others due to poverty, high fertility and 44 45 general health challenges.10,26 A Palestinian study from 2015 revealed that 26.9% of women 46 27 47 who gave birth experienced one or more morbidities. The rise in numbers of referrals after 48 introducing the new model matched the WHO and the local estimates. Thus, it seems 49 50 reasonable to suggest that the intervention improved the referral system. 51 52 53 The results furthermore showed a substantial increase in number of postnatal-care contacts for 54 55 mothers and new-borns, including home-visits. WHO recommendation for postnatal care is a 56 minimum of three postnatal contacts; and minimum one home-visit preferably during the first 57 58 10 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 11 of 20 BMJ Open BMJ Open: first published as 10.1136/bmjopen-2017-019568 on 22 March 2018.

1 2 28 3 week after birth. The result from the study consequently indicates that the implementation of 4 midwifery-led continuity models may contribute to reach such goal. 5 6 Filby et al described how lack of transportation hampered quality improvements in other rural 7 29 8 resource-constrained settings. The implementation in rural Palestine included a designated 9 vehicle and driving skills for the midwives, facilitation of transportation was consequently a 10 11 key in order to reach out to the villages and home-visits. 12 The fact that women receiving midwifery-led continuity were more frequently seen by a 13 14 doctor in the clinic after birth (20.1% vs. 4.8%), in addition to the midwife, indicate improved 15 16 interdisciplinary Forcooperation. peer When midwives review undertook home-visit only and discovered health 17 problems or risks, she involved the medical doctor. The findings also showed that there is a 18 19 systematic check of newborn by doctors in all the village clinics, and the home visit from the 20 21 midwife ads to this. The increase in and variation of, postnatal contacts including home-visits, 22 make it reasonable to conclude that the midwifery model improved both utilization and 23 24 quality of postnatal care at a cluster level. 25 26 27 Limitations of the study 28 29 The study was carried out after the implementation of the midwifery-led continuity model 30 started. This prevented a randomized allocation of clinics to intervention and control clusters. 31 32 The number of midwives available in the hospitals limited the number of clinics for http://bmjopen.bmj.com/ 33 34 implementation to a total of 15 in these regions. The ministry chose to implement the program 35 in the clinics they found appropriate. The baseline data indicate that the reason for choosing 36 37 these clinics were challenges in service provision, thus improvements could be easier 38 achieved and lead to bias. 39 40 Another limitation was weak data due to the facility-based registry did not include data on on September 29, 2021 by guest. Protected copyright. 41 23 42 individual level. This is a common problem in low-and middle income countries. Lack of 43 individual reproductive health registry prevented measuring individual impact and an intra- 44 45 cluster coefficient. It was not possible to identify when women registered at the clinic, who 46 47 came back for recurrent antenatal-visits or reasons for referrals. 48 49 50 Strength of the study and further recommendations 51 The high number of clusters and the robust cluster data strengthen the study. The 52 53 organizational leadership, engagement and adherence of the multidisciplinary team strengthen 54 55 the sustainably of a complex intervention and its applicability to real life settings. 56 57 58 11 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 12 of 20 BMJ Open: first published as 10.1136/bmjopen-2017-019568 on 22 March 2018.

1 2 3 There were high statistical significant differences for the primary outcome and important 4 secondary outcomes, also after adjusting for possible confounders. The findings make it 5 6 reasonable to conclude that the new model had effect on the utilization and some quality 7 8 indicators of the maternal service. 9 10 11 Triangulation of methods within an implementation research framework would be useful to 12 investigate the broader effect of the implementation. This is highly recommended when 13 14 introducing evidence-based interventions to improve health service delivery in real world 15 30 16 settings where contextFor is an peer important factor. reviewFurther research only should be done to investigate 17 if the model has impact on individual health outcomes for mother and newborn, and 18 19 satisfaction of care. Previous research described midwifery-led models as cost saving, also in 20 12,31 21 developing countries , nevertheless evaluation of this model`s costs would be useful. 22 23 24 Conclusion 25 The findings make it reasonable to conclude that the new model had effect on the utilization 26 27 and some quality indicators of the maternal service. 28 29 The positive change in facility-level outcomes show that clinics with the midwifery model in 30 the regions of Nablus and Jericho improved services during pregnancy and postnatally. The 31 32 findings indicate improvement of utilization and some quality indicators linked to facility- http://bmjopen.bmj.com/ 33 34 level outcomes, such as continuity, functioning referral system and postnatal home-visits. 35 The results from this study support the expansion of the model to new areas in Palestine. We 36 37 believe the model can be useful for other low- and middle-income countries to improve 38 utilization and quality of care. 39 40 on September 29, 2021 by guest.

Midwives were weekly deployed from governmental 21 22 hospitals to provide ante- and postnatal-care in rural clinics. We studied the intervention`s 23 impact on utilization and quality indicators of maternal services after two years’ experience. 24 25 Design: A non-randomized, intervention design was chosen. The study was based on registry 26 27 data only available at cluster level, two years before (2011 & 2012) and two ears after (2014 28 & 2015) the intervention. 29 30 Setting: All 53 primary health care clinics in Nablus and Jericho regions were stratified for 31 inclusion. 32 http://bmjopen.bmj.com/ 33 Primary and secondary outcomes: Primary outcome was number of antenatal visits. 34 35 Important secondary outcomes were number of referrals to specialist care and number of 36 postnatal home-visits. Differences in changes within the two groups before and after the 37 38 intervention were compared by using mixed effect models. 39 Results: 14 intervention-clinics, and 25 control-clinics were included in the study.

A statistical significant difference in number of referrals was observed 45 46 between the groups giving a ratio of rate ratios of 3.65 [2.78 – 4.78] as number of referrals 47 48 increased by a rate ratio of 3.87 in the intervention group while in the control the rate-ratio 49 was only 1.06. 50 51 Home-visits increased substantially in the intervention group, but decreased in control group 52 giving a ratio of RR 97.65 (45.20 - 210.96) 53 54 55 56 57 58 1 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 2 of 22

More research should be done to investigate if the 5 6 model had effect on individual health outcomes and satisfaction of care. 7 8 Trial registration: ClinicalTrials.gov Identifier: NCT03145571 9 10 11 Strengths and Limitations of the study 12 • The pragmatic approach strengthens the applicability to real life settings. 13 14 • The high number of clusters and the robust cluster data strengthen the study. 15 16 • A randomizedFor allocation peer of clusters review was not possible onlybecause the implementation of 17 the midwifery-led continuity model started before the study was planned. 18 19 • The ministry implemented the program in the clinics they found appropriate which 20 21 could lead to bias. 22 • The facility-based registry did not include data on individual level. 23 24 INTRODUCTION 25 As a low-middle-income country under occupation, Palestine depends largely on foreign aid.1 26 27 The Palestinian Authority is responsible for the health services for the Palestinian people 28 29 within the occupied territories of West Bank and Gaza. In 2013, the Palestinian Ministry of 30 Health, registered 61 405 births and a fertility rate of 4.0 per woman on the West Bank.2 31 32 Maternal health services were provided by the Palestinian government and private, and non- http://bmjopen.bmj.com/ 33 34 governmental organisations. Less than 1% of the women gave birth at home. Governmental 35 facilities covered 45.6% of antenatal-care in 2013. The Palestinian Multiple Indicator Cluster 36 37 Survey from 2014 found that 66.4% of rural women gave birth in governmental hospitals. Of 38 them 40.7% left hospital within 6 hours postpartum and 73% did not receive any additional 39 40 3

Protected copyright. 41 42 In 2009 the Palestinian governmental maternal services were described as of poor quality, 43 overcrowded, understaffed, including short antenatal visits lacking content, and dissatisfaction 44 45 with care.4 Overcrowded labour rooms prohibited women bringing a birth companion.5 46 47 Midwives had restricted scope of practice and little autonomy, and few worked in antenatal- 48 care.6 The clinics were not able to implement postnatal home-visits as required by 49 6 7 50 governmental standards. Poor women were less likely to have postnatal-care. 51 Poverty, deprived infrastructure, military checkpoints and armed Israeli settlers restricts 52 53 freedom of movement and reduces access to central health-facilities and legal aid in rural 54 8,9 55 areas. During an escalation of the conflict between the years 2000 to 2006, it was reported 56 that 69 women gave birth at military checkpoints, causing casualties for both women and 57 58 2 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 3 of 22 BMJ Open

Although the political situation 4 in the West Bank was less volatile the following decade, rural women are vulnerable and 5 6 depend more on governmental facilities than women in urban areas, as rural private services 7 10 8 are scarce. 9 Several studies describe how midwifery-led continuity models improved health for mothers 10 11-16 11 and babies. Most studies were from high-income countries. World Health Organisation 12 (WHO) recommends implementation and research on midwifery-led continuity models to 13 14 improve quality in low- and middle-income countries.17 Two main ways of organizing such 15 16 models are describedFor in the peer literature. In reviewthe case-load model only one midwife cares for up to 40 17 women and facilitate relational continuity, while in the team-midwifery model a group of 4-6 18 19 midwives can provide care for up to 360 women through pregnancy, birth and postnatally. 20 11,17 21 Ideally, in both models, women are cared for during birth by a known midwife. 22 To improve services in rural areas, the Palestinian Ministry of Health in cooperation with the 23 24 non-governmental humanitarian organization Norwegian Aid Committee (NORWAC), 25 launched implementation of a modified midwifery-led continuity, case-load-model, in 2013, 26 27 starting in Nablus and Jericho Governmental hospitals and surrounding villages. The 28 29 implementation engaged several levels in the ministry of health and the involved 30 communities, to overcome known barriers to quality of care.18 31 32 The aim of this study was to investigate whether the Palestinian midwifery-led continuity http://bmjopen.bmj.com/ 33 34 model had impact on the utilization of maternity services and selected quality indicators at the 35 two regions` clinics after two years of experience. 36 37 38 METHODS 39 40

Implementation of the Palestinian Midwifery-led continuity model on September 29, 2021 by guest. Protected copyright. 41 42 The modified case-load model aimed at establishing a relationship between the pregnant 43 woman and her midwife, during pregnancy and the postnatal period. The midwife also 44 45 worked at the governmental hospital, where most woman would give birth unless they chose a 46 47 private hospital. 48 Midwives in Nablus and Jericho governmental hospitals were assigned, trained, and took 49 50 driving lessons to obtain driving license. Under supervision, they provided ante-and postnatal 51 care in vicinity villages` governmental clinics. The hospital in Nablus had enough midwives 52 53 to serve ten villages per week, meaning two midwives would leave hospital each weekday, 54 55 five days a week. Jericho, served five villages, one midwife visited one village each day.

All midwives worked full time, as part time employment was not 4 possible in the Ministry of Health. The same midwife visited the same village, usually once a 5 6 week. If the designated midwife had vacation or sick leave one of the other midwives would 7 8 cover her village. The ideal case load per midwife was around 50 pregnant women yearly, but 9 should not exceed 100. Thus, the smallest village with 16 registered pregnant women per year 10 11 was visited only every second week and the largest village with 163 registered pregnant 12 women was shared by two midwives weekly. The remaining working days the midwife spent 13 14 in the labour ward. All pregnant women were informed that their midwife during pregnancy 15 16 also worked at theFor local governmental peer hospital. review Independent onlyof birth place, all women 17 registered at the clinic should be offered postnatal home visits. All pregnant women were 18 19 informed that the limited numbers of midwives, and the large workload in the labour ward, 20 21 made it difficult to ensure a known midwife during labour. Women were given the phone 22 number for their midwife in case of an emergency. The level of relational continuity through 23 24 the case-load model in Palestine was overall limited to the ante- and postnatal period. 25 Nevertheless, a relational continuity was possible also during birth, if the known midwife was 26 27 on duty. Implementing the model aimed to strengthening the relationship between the woman 28 29 and her midwife, improve interdisciplinary cooperation, and reduce the barrier between 30 hospital and primary health care. The midwives received driving lessons, and used designated 31 32 cars with the Ministry of Health logo, and marked Midwifery Care, to facilitate transportation http://bmjopen.bmj.com/ 33 34 to villages and homes. Standard care in the clinics without this model was offered mainly 35 from nurses or midwives and medical doctors (GP) working only in primary health care. 36 37 38 Study design 39 40 As the implementation started before the study, a non-randomized intervention design was on September 29, 2021 by guest.

Clinics 44 45 where the model was implemented were compared with clinics where the model was not 46 47 implemented. Both arms of the study followed the same written governmental procedures. 48 The study was part of an implementation research project aiming at documenting the effect of 49 50 the midwifery-led continuity model. The study was approved by the Regional ethical 51 committee of South East Norway and by the Palestinian Ministry of Health. 52 53 54 55 56 57 58 4 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 5 of 22 BMJ Open

Before fitting, the outcome variables were divided by the number of registered 7 8 pregnant women, or newborn, to calculate average values. Variance weights for each average 9 were then computed and included in a variance formula in the model because of 10 11 heteroscedasticity, since the computed averages are based on different numbers of pregnant 12 women. 13 14 15 16 Mixed effects PoissonFor regressions peer were usedreview to fit non-normally only distributed count outcomes, 17 and an offset variable was used to adjust for the total number of (individual) registrations that 18 19 were under risk in the models. 20 21 22 Measured confounding variables, which could have influenced the key estimates, were: the 23 24 villages population size, if the clinic had an employed community midwife and laboratory 25 equipment, regular military check point between village and hospital, and distant from 26 27 hospital.

The women’s increased 4 adherence to service in clinics with midwifery-led continuity may indicate that women 5 6 experienced improved quality of the services. Relational continuity is an important tool to 7 16 8 enhance communication and thus satisfaction of care. The association between improved 9 quality of care and increased utilization is supported by several previous studies, and by WHO 10 11 recommendations, to improve utilization and quality by introducing midwife-led continuity of 12 care.12,14,17,18 13 14 It is a possibility that the pregnant woman would feel safe knowing that the midwife 15 16 following her throughoutFor pregnancypeer also review worked at the public only hospital where she would give 17 birth, and that her midwife would visit her at home after birth. Due to the heavy workload, the 18 19 midwives could not always be on call to attend birth. Midwifery-led continuity of care in 20 21 settings with few midwife resources and heavy workload, must balance the demands on the 22 midwives. Although women were not guaranteed that the same midwife providing them ante- 23 24 and postnatal care would attend their birth, their midwife`s connection to the governmental 25 hospital might have reduced the alien barrier to the hospital, and restored feeling of security 26 27 for the rural women. 28 29 A qualitative study investigated midwives’ experience from working in a similar model in 30 Ramallah region from 2007 to 2011. The midwives described how the model enabled them to 31 32 give individualized care and how the broader scope of practice and increased autonomy gave http://bmjopen.bmj.com/ 33 21 34 them important experience and tools to help. This can explain women adherence to service, 35 because building relationship with competent, respectful and motivated midwives probably 36 37 increased their wish to return to receive more care. 38 39 40 In the intervention group a change in referral mechanisms was observed. The midwives on September 29, 2021 by guest. Protected copyright. 41 42 working in the new model identified significantly more risk factors causing referral to higher 43 level of care, than in clinics with standard care. The identification of more women with 44 45 abnormal blood sugar level indicates that the model led to identification of important risk 46 47 factors. The proportion of pregnant women referred to higher level of care increased to 25.6% 48 with the new model vs. 13% with standard care during the study period. The proportion in the 49 50 new model is in line with the WHO-estimate presented in guidelines from 2001, that in 51 general 25% of pregnant women would need additional antenatal-care due to health 52 53 complications before or during pregnancy.22 The village clinics had little, if any, technical 54 55 resources to investigate risk signs, so referral to higher level of care was necessary to follow 56 up any possible complications. 57 58 11 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 12 of 22

BMJ Open: first published as 10.1136/bmjopen-2017-019568 on 22 March 2018. Downloaded from 1 2 3 One important quality indicator of antenatal-care is the ability to detect possible 4 complications and involve specialist care when necessary. Kearns et al previously 5 6 demonstrated that improved referral networks was a key element for improving quality in 7 23 8 low-resource settings. The process of information and referral within the system is also 9 highlighted by the WHO framework as one core indicator of quality of services.24,25 Some 10 11 countries have much higher potential health risks than others due to poverty, high fertility and 12 general health challenges.10,26 A Palestinian study from 2015 revealed that 26.9% of women 13 14 who gave birth experienced one or more morbidities.27 The rise in numbers of referrals after 15 16 introducing the newFor model peer matched the WHOreview and the local estimates.only Thus, it seems 17 reasonable to suggest that the intervention improved the referral system. 18 19 20 21 The results furthermore showed a substantial increase in number of postnatal-care contacts for 22 mothers and new-borns, including home-visits. WHO recommendation for postnatal care is a 23 24 minimum of three postnatal contacts; and minimum one home-visit preferably during the first 25 week after birth.28 The result from the study consequently indicates that the implementation of 26 27 midwifery-led continuity models may contribute to reach such goal. 28 29 Filby et al described how lack of transportation hampered quality improvements in other rural 30 resource-constrained settings.29 The implementation in rural Palestine included a designated 31 32 vehicle and driving skills for the midwives, facilitation of transportation was consequently a http://bmjopen.bmj.com/ 33 34 key in order to reach out to the villages and home-visits. 35 The fact that women receiving midwifery-led continuity were more frequently seen by a 36 37 doctor in the clinic after birth (20.1% vs. 4.8%), in addition to the midwife, indicate improved 38 interdisciplinary cooperation. When midwives undertook home-visit and discovered health 39 40 problems or risks, she involved the medical doctor. The findings also showed that there is a on September 29, 2021 by guest.

The increase in and variation of, postnatal contacts including home-visits, 44 45 make it reasonable to conclude that the midwifery model improved both utilization and 46 47 quality of postnatal care at a cluster level. 48 49 50 Limitations of the study 51 The study was carried out after the implementation of the midwifery-led continuity model 52 53 started. This prevented a randomized allocation of clinics to intervention and control clusters. 54 55 The number of midwives available in the hospitals limited the number of clinics for 56 implementation to a total of 15 in these regions.

The baseline data indicate that the reason for choosing 4 these clinics were challenges in service provision, thus improvements could be easier 5 6 achieved and lead to bias. 7 8 Another limitation was weak data due to the facility-based registry did not include data on 9 individual level. This is a common problem in low-and middle income-countries.23 Lack of 10 11 individual reproductive health registry prevented measuring individual impact and an intra- 12 cluster coefficient. It was not possible to identify when women registered at the clinic, who 13 14 came back for recurrent antenatal-visits or reasons for referrals. 15 16 For peer review only 17 Strength of the study and further recommendations 18 19 The high number of clusters and the robust cluster data strengthen the study. The 20 21 organizational leadership, engagement and adherence of the multidisciplinary team strengthen 22 the sustainably of a complex intervention and its applicability to real life settings. The 23 24 findings make it reasonable to conclude that the new model had effect on the utilization and 25 some quality indicators of the maternal service. The study can be a useful tool in power- 26 27 calculations and planning of randomized trials for future implementation of the model. 28 29 30 Triangulation of methods within an implementation research framework would be useful to 31 32 investigate the broader effect of the implementation. This is highly recommended when http://bmjopen.bmj.com/ 33 34 introducing evidence-based interventions to improve health service delivery in real world 35 settings where context is an important factor.30 Further research should be done to investigate 36 37 if the model has impact on individual health outcomes for mother and newborn, and 38 satisfaction of care. Previous research described midwifery-led models as cost saving, also in 39 40 developing countries.12,31 A study of this model`s cost-effectiveness would be useful. The on September 29, 2021 by guest. Protected copyright. 41 42 general understaffing in both primary and secondary governmental health services should be 43 taken in consideration. This demanded upscaling number of midwives to improve quality, at 44 45 some cost. The extra midwives were employed at the hospitals to serve the community, at the 46 47 same time the hospital got more midwives to share the shifts. Also, the midwives widened 48 their scope of practice and experience, while linking the primary and secondary healthcare. 49 50 The cost of transportation was reduced to a minimum by enabling the midwives to drive the 51 vehicle themselves, employing drivers would have added unsustainable cost to the model. 52 53 54 55 Conclusion 56 57 58 13 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 14 of 22

In 2013, the Palestinian Ministry of Health registered 48 61 405 births and a fertility rate of 4.0 per woman in the West Bank.2 Maternal health services 49 50 were provided by the Palestinian government, and by private, and non-governmental 51 organisations. Less than 1% of the women give birth at home. Governmental facilities 52 53 covered 45.6% of antenatal care in 2013. The Palestinian Multiple Indicator Cluster Survey 54 55 from 2014 found that 66.4% of rural women gave birth in governmental hospitals.

Downloaded from 1 2 3 40.7% left hospital within 6 hours postpartum and 73% did not receive any additional 4 postnatal care.3 5 6 In 2009 the Palestinian governmental maternal services were described as of poor quality due 7 8 to concerns for being overcrowded and understaffed. Patient reported dissatisfaction with care 9 as antenatal visits were short and lacking content.4 Overcrowded labour rooms prohibited 10 5 11 women from bringing a birth companion. Midwives had restricted scope of practice and little 12 autonomy, and were not used by the Ministry as antenatal care providers.4 The clinics were 13 14 not able to carry out postnatal home visits as required by governmental standards.6 Poor 15 7 16 women were lessFor likely to havepeer postnatal review care. only 17 Poverty, deprived infrastructure, military checkpoints and armed Israeli settlers restrict 18 19 freedom of movement and reduces access to central health-facilities and legal assistance in 20 8,9 21 rural areas. During an escalation of the conflict between the years 2000 to 2006, it was 22 reported that 69 women gave birth at military checkpoints, causing casualties in both mothers 23 4 24 and babies, as they were not allowed to reach hospitals. Although the political situation in the 25 West Bank was less volatile in the following decade, rural women are still vulnerable and 26 27 depend more on governmental facilities than women in urban areas, as rural private services 28 9 29 are scarce. 30 Several studies describe how midwife-led continuity models improved health for mothers and 31 32 babies. Most studies were from high-income countries.10-16 The World Health Organisation http://bmjopen.bmj.com/ 33 34 (WHO) recommends implementation and research on midwife-led continuity models to 35 improve quality in low- and middle-income countries.17 Two main ways of organizing such 36 37 models are described in the literature. In the case-load model one midwife cares for up to 45 38 women and facilitate relational continuity, while in the team-midwifery model a group of 4-6 39 40 midwives can provide care for up to 360 women through the pregnancy, intrapartum and on September 29, 2021 by guest.

Ideally, in both models, women during labour are cared for by a known 43 midwife.11,17 44 45 To improve services in rural areas, the Palestinian Ministry of Health, in cooperation with the 46 47 non-governmental humanitarian organization Norwegian Aid Committee (NORWAC), 48 launched the implementation of a modified midwife-led continuity, case-load-model, in 2013, 49 50 starting in the Nablus and Jericho Governmental hospitals and surrounding villages. The 51 implementation involved the communities as well as several levels in the Ministry of Health, 52 53 to overcome known barriers to quality of care.18 54 55 56 57 58 3 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 4 of 23

Downloaded from 1 2 3 The aim of this study was to investigate whether the Palestinian midwife-led continuity model 4 had an impact on the utilization of maternity services and selected quality indicators at the 5 6 two regions’ clinics after two years of experience. 7 8 9 METHODS 10 11 Implementation of the Palestinian Midwife-led continuity model 12 The modified case-load model aimed at establishing a relationship between the pregnant 13 14 woman and her midwife, during pregnancy and the postnatal period. The midwife also 15 16 worked at the governmentalFor peer hospital, where review most women would only give birth unless they chose a 17 private hospital. 18 19 Once assigned, midwives in Nablus and Jericho governmental hospitals received training. 20 21 Under supervision, they provided antenatal care in clinics and postnatal home visits in the 22 surrounding villages. The hospital in Nablus had enough midwives to serve ten villages per 23 24 week, meaning two midwives would leave hospital each weekday, five days a week. 25 Midwives from Jericho hospital served five villages in the Jordan Valley, with one midwife 26 27 visiting one village every weekday. Three extra midwives were employed in the hospital in 28 29 Nablus, and two in Jericho, to maintain the capacity at the labour ward. All midwives worked 30 full time, as part time employment was not possible at the Ministry of Health. The same 31 32 midwife visited the same village, usually once a week. If the designated midwife was on http://bmjopen.bmj.com/ 33 34 holiday or sick leave one of the other midwives would cover her village. The ideal case load 35 per midwife was around 50 pregnant women yearly, but should not exceed 100.

Downloaded from 1 2 3 recommendation was revised in 2016 to a minimum of eight antenatal visits to reduce 4 perinatal mortality and improve women’s satisfaction.17,18,20 The women’s increased 5 6 adherence to service in clinics with midwife-led continuity may indicate that women 7 8 experienced improved quality of the services. Relational continuity is an important tool to 9 enhance communication and thus satisfaction with care.16 The association between improved 10 11 quality of care and increased utilization is supported by several previous studies, and by WHO 12 recommendations, to improve utilization and quality by introducing midwife-led continuity of 13 14 care.12,14,17,18 15 16 It is a possibilityFor that the pregnant peer woman review would feel safe knowing only that the midwife 17 following her throughout pregnancy also worked at the public hospital where she would give 18 19 birth, and that her midwife would visit her at home after birth. Due to the heavy workload, the 20 21 midwives could not be on call to attend birth. Midwife-led continuity of care in settings with 22 few midwife resources and heavy workload, must balance the demands on the midwives. 23 24 Although women were not guaranteed that the same midwife providing them antenatal and 25 postnatal care would attend their labour, their midwife’s connection to the governmental 26 27 hospital might have reduced the alien barrier to the hospital, and restored a feeling of security 28 29 for the rural women. 30 A qualitative study investigated midwives’ experience of working with a similar model in the 31 32 Ramallah region from 2007 to 2011. The midwives described how the model enabled them to http://bmjopen.bmj.com/ 33 34 give individualized care and how the broader scope of practice and increased autonomy gave 35 them important experience and tools for their work.21 This could serve to explain women’s 36 37 adherence to the antenatal service, because building a relationship with competent, respectful 38 and motivated midwives probably increased their wish to return to receive more care. 39 40 on September 29, 2021 by guest. Protected copyright. 41 42 In the intervention group, a change in referral mechanisms was observed. The midwives 43 working with the new model identified significantly more risk factors leading to referral to 44 45 higher level of care, than in clinics with standard care. The finding of more women with 46 47 abnormal blood sugar level indicates that the model improved the identification of important 48 risk factors. The proportion of pregnant women referred to higher level of care increased to 49 50 25.6% with the new model vs. 13% with standard care during the study period. The 51 proportion in the new model is in line with the WHO-estimate presented in guidelines from 52 53 2001, that in general 25% of pregnant women would need additional antenatal care due to 54 22 55 health complications before or during pregnancy.

Downloaded from 1 2 3 technical resources to investigate risk signs, so referral to higher level of care was necessary 4 to follow up any possible complications. 5 6 One important quality indicator of antenatal care is the ability to detect possible complications 7 8 and involve specialist care when necessary. Kearns et al. (2015) demonstrate that improved 9 referral networks is a key element for improving quality in low-resource settings.23 The 10 11 process of information and referral within the system is also highlighted by the WHO 12 framework as one core indicator of quality of services.24,25 Some countries have much higher 13 14 level of maternal health risks than others due to poverty, high fertility rate and general health 15 10,26 16 challenges. AFor Palestinian peer study from review2015 revealed that 26.9%only of women who gave birth 17 experienced one or more morbidities.27 The rise in numbers of referrals after introducing the 18 19 new model matched the WHO and the local estimates. Thus, it seems reasonable to suggest 20 21 that the intervention improved the referral system. 22 23 24 The results furthermore showed a substantial increase in the number of postnatal care contacts 25 for mothers and new-borns, including home visits. The WHO recommendation for postnatal 26 27 care is a minimum of three postnatal contacts; and a minimum of one home visit preferably 28 28 29 during the first week after birth. The result from the study consequently indicates that the 30 implementation of midwife-led continuity models may contribute to reach such a goal. 31 32 Filby et al. (2016) describe how lack of transportation hamper quality improvements in other http://bmjopen.bmj.com/ 33 29 34 rural resource-constrained settings. The implementation in rural Palestine included a 35 designated vehicle and driving skills for the midwives, facilitation of transportation was 36 37 consequently a key factor in reaching out to the villages and home visits. 38 The fact that women receiving midwife-led continuity were more frequently seen by a doctor 39 40 in the clinic after birth (20.1% vs. 4.8%), in addition to the midwife, indicate improved on September 29, 2021 by guest.

The findings also showed that there was a 44 45 systematic check of newborn babies by doctors in all the village clinics, and the home visit 46 47 from the midwife added to this. The increase in, and variation of, postnatal contacts including 48 home visits, make it reasonable to conclude that the midwifery model improved both 49 50 utilization and quality of postnatal care at a cluster level. 51 52 53 Limitations of the study 54 55 The study was carried out after the implementation of the midwife-led continuity model 56 started. This prevented a randomized allocation of clinics to intervention and control clusters. 57 58 13 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml BMJ Open Page 14 of 23

The baseline data show that a reason for 7 8 choosing these clinics were due to challenges in service provision, thus improvements could 9 have been easier achieved and lead to bias. 10 11 Another limitation was weak data because the facility-based registry did not include data at 12 individual level. This is a common problem in low-and middle income-countries.23 Lack of an 13 14 individual reproductive health registry prevented measuring individual impact and an intra- 15 16 cluster coefficient.For Thus, itpeer was not possible review to know, when womenonly registered at the clinic, or 17 who came back for recurrent antenatal-visits, or the reasons for referrals. 18 19 20 21 Strength of the study and further recommendations 22 The high number of clusters and the robust cluster data strengthen the study. The 23 24 organizational leadership, engagement and adherence of the multidisciplinary team strengthen 25 the sustainably of a complex intervention and its applicability to real life settings. The 26 27 findings make it reasonable to conclude that the new model had an effect on the utilization 28 29 and on some quality indicators of the maternal services. The study can be a useful tool in 30 power-calculations and planning of randomized trials for future implementation of the model. 31 32 http://bmjopen.bmj.com/ 33 34 Triangulation of methods within an implementation research framework would be useful to 35 investigate the broader effect of the implementation. This is highly recommended when 36 37 introducing evidence-based interventions to improve health service delivery in real world 38 settings where context is an important factor.30 Further research should be done to investigate 39 40 if the model could have impact on individual health outcomes for mother and newborn, and on September 29, 2021 by guest.

Previous research has described midwife-led models as a cost saving 43 way to improve maternal health in developing countries.12,31 A study of this model’s cost- 44 45 effectiveness would be useful. The general understaffing of both primary and secondary 46 47 governmental health services should be taken into consideration. This calls for an increase in 48 the number of midwives to improve quality. By implementing the model, more midwives 49 50 were employed at the hospitals to serve the community, enhancing the workforce of trained 51 midwives in both primary and secondary health service. The benefit of the midwife’s broader 52 53 scope of practice and experience, and the improved interdisciplinary cooperation should be 54 55 investigated. The cost of transportation was reduced to a minimum by enabling the midwives 56 57 58 14 59 60 For peer review only - http://bmjopen.bmj.com/site/about/guidelines.xhtml Page 15 of 23 BMJ Open

We 20 21 believe the model can be useful for other low- and middle-income countries to improve 22 utilization and quality of care. 23 24 25 26 27 Acknowledgements The authors would like to thank the Palestinian Ministry of Health for 28 29 their efforts in implementing the model, and preparing and sharing of their health registry.
