Introduction

In 2016, at the start of the Sustainable Development Goals (SDGs) era, pregnancy-related preventable morbidity and mortality remains unacceptably high. While substantial progress has been made, countries need to consolidate and increase these advances, and to expand their agendas to go beyond survival, with a view to maximizing the health and potential of their populations.

The World Health Organization (WHO) envisions a world where every pregnant woman and newborn receives quality care throughout the pregnancy, childbirth and the postnatal period. Within the continuum of reproductive health care, antenatal care (ANC) provides a platform for important health-care functions, including health promotion, screening and diagnosis, and disease prevention. It has been established that by implementing timely and appropriate evidence-based practices, ANC can save lives. Crucially, ANC also provides the opportunity to communicate with and support women, families and communities at a critical time in the course of a woman’s life. The process of developing these recommendations on ANC has highlighted the importance of providing effective communication about physiological, biomedical, behavioural and sociocultural issues, and effective support, including social, cultural, emotional and psychological support, to pregnant women in a respectful way. These communication and support functions of ANC are key, not only to saving lives, but to improving lives, health-care utilization and quality of care. Women’s positive experiences during ANC and childbirth can create the foundations for healthy motherhood.

This is a comprehensive WHO guideline on routine ANC for pregnant women and adolescent girls. The aim is for these recommendations to complement existing WHO guidelines on the management of specific pregnancy- related complications. The guidance is intended to reflect and respond to the complex nature of the issues surrounding the practice and delivery of ANC, and to prioritize person-centred health and well-being – not only the prevention of death and morbidity – in accordance with a human rights-based approach.

The scope of this guideline was informed by a systematic review of women’s views, which shows that women want a positive pregnancy experience from ANC. A positive pregnancy experience is defined as maintaining physical and sociocultural normality, maintaining a healthy pregnancy for mother and baby (including preventing or treating risks, illness and death), having an effective transition to positive labour and birth, and achieving positive motherhood (including maternal self-esteem, competence and autonomy).

Recognizing that a woman’s experience of care is key to transforming ANC and creating thriving families and communities, this guideline addresses the following questions: nnWhat are the evidence-based practices during ANC that improve outcomes and lead to a positive pregnancy experience? nnHow should these practices be delivered?

Guideline development methods

These ANC recommendations are intended to inform the development of relevant health-care policies and clinical protocols. The guideline was developed using standard operating procedures in accordance with the process described in the WHO handbook for guideline development. Briefly, these procedures include: (i) identification of priority questions and outcomes; (ii) evidence retrieval and synthesis; (iii) assessment of the evidence; (iv) formulation of the recommendations; and (v) planning for implementation, dissemination, impact evaluation and updating of the guideline. The quality of the scientific evidence underpinning the recommendations was graded using the Grading of Recommendations Assessment, Development and

A.1.2: In undernourished populations, nutrition education on increasing Context-specific daily energy and protein intake is recommended for pregnant women to recommendation reduce the risk of low-birth-weight neonates.

A.1.3: In undernourished populations, balanced energy and protein Context-specific dietary supplementation is recommended for pregnant women to reduce recommendation the risk of stillbirths and small-for-gestational-age neonates.

A.1.4: In undernourished populations, high-protein supplementation Not recommended is not recommended for pregnant women to improve maternal and perinatal outcomes.

Iron and folic acid A.2.1: Daily oral iron and folic acid supplementation with 30 mg to 60 mg Recommended supplements of elemental ironb and 400 g (0.4 mg) of folic acidc is recommended for pregnant women to prevent maternal anaemia, puerperal sepsis, low birth weight, and preterm birth.d

A.2.2: Intermittent oral iron and folic acid supplementation with 120 Context-specific mg of elemental irone and 2800 g (2.8 mg) of folic acid once weekly is recommendation recommended for pregnant women to improve maternal and neonatal outcomes if daily iron is not acceptable due to side-effects, and in populations with an anaemia prevalence among pregnant women of less than 20%.f

Calcium A.3: In populations with low dietary calcium intake, daily calcium Context-specific supplements supplementation (1.5–2.0 g oral elemental calcium) is recommended for recommendation pregnant women to reduce the risk of pre-eclampsia.g

Vitamin A A.4: Vitamin A supplementation is only recommended for pregnant Context-specific supplements women in areas where vitamin A deficiency is a severe public health recommendation problem,h to prevent night blindness.i

a. A healthy diet contains adequate energy, protein, vitamins and minerals, obtained through the consumption of a variety of foods, including green and orange vegetables, meat, fish, beans, nuts, whole grains and fruit. b. The equivalent of 60 mg of elemental iron is 300 mg of ferrous sulfate hepahydrate, 180 mg of ferrous fumarate or 500 mg of ferrous gluconate. c. Folic acid should be commenced as early as possible (ideally before conception) to prevent neural tube defects. d. This recommendation supersedes the previous recommendation found in the WHO publication Guideline: daily iron and folic acid supplementation in pregnant women (2012). e. The equivalent of 120 mg of elemental iron equals 600 mg of ferrous sulfate heptahydrate, 360 mg of ferrous fumarate or 1000 mg of ferrous gluconate. f. This recommendation supersedes the previous recommendation in the WHO publication Guideline: intermittent iron and folic acid supplementation in non-anaemic pregnant women (2012). g. This recommendation is consistent with the WHO recommendations for prevention and treatment of pre-eclampsia and eclampsia (2011) and supersedes the previous recommendation found in the WHO publication Guideline: calcium supplementation in pregnant women (2013). h. Vitamin A deficiency is a severe public health problem if > 5% of women in a population have a history of night blindness in their most recent pregnancy in the previous 3–5 years that ended in a live birth, or if > 20% of pregnant women have a serum retinol level < 0.70 mol/L. Determination of vitamin A deficiency as a public health problem involves estimating the prevalence of deficiency in a population by using specific biochemical and clinical indicators of vitamin A status. i. This recommendation supersedes the previous recommendation found in the WHO publication Guideline: vitamin A supplementation in pregnant women (2011).

1.1 Background near-misses (9), ANC also provides an important opportunity to prevent and manage concurrent International human rights law includes fundamental diseases through integrated service delivery (10). commitments of states to enable women and adolescent girls to survive pregnancy and childbirth In low- and middle-income countries (LMICs), ANC as part of their enjoyment of sexual and reproductive utilization has increased since the introduction in health and rights and living a life of dignity (1). The 2002 of the WHO ANC model, known as focused World Health Organization (WHO) envisions a world ANC (FANC) or basic ANC, which is a goal- where “every pregnant woman and newborn receives orientated approach to delivering evidence-based quality care throughout the pregnancy, childbirth and interventions carried out at four critical times during the postnatal period” (2). However, approximately pregnancy (11, 12). However, globally, during the 303 000 women and adolescent girls died as a result period 2007–2014, only 64% of pregnant women of pregnancy and childbirth-related complications in attended the WHO-recommended minimum four 2015 (3). Around 99% of maternal deaths occur in contacts for ANC, suggesting that much more work low-resource settings and most can be prevented (4). needs to be done to address ANC utilization and Similarly, approximately 2.6 million babies were quality. stillborn in 2015, also mainly in low-resource settings (5). Nevertheless, there is evidence that Currently, WHO guidance on routine ANC is effective interventions exist at reasonable cost for the fragmented, with related recommendations published prevention or treatment of virtually all life-threatening across several different WHO guidelines and maternal complications (6), and almost two thirds practical manuals. The 2002 FANC implementation of the global maternal and neonatal disease burden manual, for example (12), does not contain relevant could be alleviated through optimal adaptation and context-specific guidance, which needs to be sought uptake of existing research findings (7). But a human elsewhere. In addition, evidence on the possible harm rights-based approach is not just about avoiding of the FANC model has recently become available, death and morbidity – it is about enabling health and necessitating a review. well-being while respecting dignity and rights. This up-to-date, consolidated guideline for routine Antenatal care (ANC) can be defined as the care ANC has been produced by the WHO Department provided by skilled health-care professionals to of Reproductive Health and Research (RHR), in pregnant women and adolescent girls in order to collaboration with the Department of Nutrition for ensure the best health conditions for both mother Health and Development (NHD) and the Department and baby during pregnancy. The components of of Maternal, Newborn, Child and Adolescent Health ANC include: risk identification; prevention and (MCA), as part of WHO’s normative work on management of pregnancy-related or concurrent supporting evidence-informed policies and practices. diseases; and health education and health promotion. By reviewing, updating and bringing together ANC- related WHO recommendations regarding “what” ANC reduces maternal and perinatal morbidity should be offered and “how” it should be delivered and mortality both directly, through detection and in the form of this guideline, it is hoped that policy- treatment of pregnancy-related complications, and makers will more easily be able to adapt, adopt indirectly, through the identification of women and and implement these new ANC recommendations, girls at increased risk of developing complications presented in Chapter 3, which have also been during labour and delivery, thus ensuring referral configured to form the 2016 WHO ANC model, to an appropriate level of care (8).

A scoping review of what women want from ANC and what outcomes they value informed the ANC guideline (13). Evidence showed that women from high-, medium- and low-resource settings valued having a positive pregnancy experience, the components of which included the provision of effective clinical practices (interventions and tests, including nutritional supplements), relevant and timely information (including dietary and nutritional advice) and psychosocial and emotional support, by knowledgeable, supportive and respectful health-care practitioners, to optimize maternal and newborn health (high confidence in the evidence).

A.1: Dietary interventions

A1.1: Counselling on healthy eating and physical activity

RECOMMENDATION A.1.1: Counselling about healthy eating and keeping physically active during pregnancy is recommended for pregnant women to stay healthy and to prevent excessive weight gain during pregnancy. (Recommended)

Remarks • A healthy diet contains adequate energy, protein, vitamins and minerals, obtained through the consumption of a variety of foods, including green and orange vegetables, meat, fish, beans, nuts, whole grains and fruit (41). • Stakeholders may wish to consider culturally appropriate healthy eating and exercise interventions to prevent excessive weight gain in pregnancy, particularly for populations with a high prevalence of overweight and obesity, depending on resources and women’s preferences. Interventions should be woman-centred and delivered in a non-judgemental manner, and developed to ensure appropriate weight gain (see further information in points below). • A healthy lifestyle includes aerobic physical activity and strength-conditioning exercise aimed at maintaining a good level of fitness throughout pregnancy, without trying to reach peak fitness level or train for athletic competition. Women should choose activities with minimal risk of loss of balance and fetal trauma (42). • Most normal gestational weight gain occurs after 20 weeks of gestation and the definition of “normal” is subject to regional variations, but should take into consideration pre-pregnant body mass index (BMI). According to the Institute of Medicine classification (43), women who are underweight at the start of pregnancy (i.e. BMI < 18.5 kg/m2) should aim to gain 12.5–18 kg, women who are normal weight at the start of pregnancy (i.e. BMI 18.5–24.9 kg/m2) should aim to gain 11.5–16 kg, overweight women (i.e. BMI 25–29.9 kg /m 2) should aim to gain 7–11.5 kg, and obese women(i.e. BMI > 30 kg/m2) should aim to gain 5–9 kg. • Most evidence on healthy eating and exercise interventions comes from high-income countries (HICs), and the GDG noted that that there are at least 40 ongoing trials in HICs in this field. The GDG noted that research is needed on the effects, feasibility and acceptability of healthy eating and exercise interventions in LMICs. • Pregnancy may be an optimal time for behaviour change interventions among populations with a high prevalence of overweight and obesity, and the longer-term impact of these interventions on women, children and partners needs investigation. • The GDG noted that a strong training package is needed for practitioners, including standardized guidance on nutrition. This guidance should be evidence-based, sustainable, reproducible, accessible and adaptable to different cultural settings.

It also suggests that women may be less likely to engage with health services if advice Resources is delivered in a hurried or didactic manner (high Cost implications of diet and exercise interventions confidence in the evidence) (22). Therefore, these for health services are highly variable. For example, types of interventions are more likely to be acceptable supervised diet and exercise interventions can if the interventions are delivered in an unhurried have high associated costs, mainly due to staff and supportive way, which may also facilitate better costs for time spent supervising, while counselling engagement with ANC services.

A.2: Iron and folic acid supplements

A.2.1: Daily iron and folic acid supplements

RECOMMENDATION A.2.1: Daily oral iron and folic acid supplementation with 30 mg to 60 mg of elemental irona and 400 µg (0.4 mg) folic acidb is recommended for pregnant women to prevent maternal anaemia, puerperal sepsis, low birth weight, and preterm birth.c (Recommended)

Remarks • This recommendation supersedes the 2012 WHO Guideline: daily iron and folic acid supplementation in pregnant women (36) and should be considered alongside Recommendation A.2.2 on intermittent iron. • In settings where anaemia in pregnant women is a severe public health problem (i.e. where at least 40% of pregnant women have a blood haemoglobin [Hb] concentration < 110 g/L), a daily dose of 60 mg of elemental iron is preferred over a lower dose. • In the first and third trimesters, the Hb threshold for diagnosing anaemia is 110 g/L; in the second trimester, the threshold is 105 g/L (50). • If a woman is diagnosed with anaemia during pregnancy, her daily elemental iron should be increased to 120 mg until her Hb concentration rises to normal (Hb 110 g/L or higher) (34, 51). Thereafter, she can resume the standard daily antenatal iron dose to prevent recurrence of anaemia. • Effective communication with pregnant women about diet and healthy eating – including providing information about food sources of vitamins and minerals, and dietary diversity – is an integral part of preventing anaemia and providing quality ANC. • Effective communication strategies are vital for improving the acceptability of, and adherence to, supplementation schemes. • Stakeholders may need to consider ways of reminding pregnant women to take their supplements and of assisting them to manage associated side-effects. • In areas with endemic infections that may cause anaemia through blood loss, increased red cell destruction or decreased red cell production, such as malaria and hookworm, measures to prevent, diagnose and treat these infections should be implemented. • Oral supplements are available as capsules or tablets (including soluble tablets, and dissolvable and modified-release tablets) (52). Establishment of a quality assurance process is important to guarantee that supplements are manufactured, packaged and stored in a controlled and uncontaminated environment (53). • A better understanding of the etiology of anaemia (e.g. malaria endemnicity, haemoglobinopathies) and the prevalence of risk factors is needed at the country level, to inform context-specific adaptations of this recommendation. • Standardized definitions of side-effects are needed to facilitate monitoring and evaluation. • Development and improvement of integrated surveillance systems are needed to link the assessment of anaemia and iron status at the country level to national and global surveillance systems. • To reach the most vulnerable populations and ensure a timely and continuous supply of supplements, stakeholders may wish to consider task shifting the provision of iron supplementation in community settings with poor access to health-care professionals (see Recommendation E.6.1, in section E: Health systems interventions to improve the utilization and quality of ANC).

a The equivalent of 60 mg of elemental iron is 300 mg of ferrous sulfate hepahydrate, 180 mg of ferrous fumarate or 500 mg of ferrous gluconate. b Folic acid should be commenced as early as possible (ideally before conception) to prevent neural tube defects. c This recommendation supersedes the previous WHO recommendation found in the 2012 Guideline: daily iron and folic acid supplementation in pregnant women (36).

A.2.2: Intermittent iron and folic acid supplements

RECOMMENDATION A.2.2: Intermittent oral iron and folic acid supplementation with 120 mg of elemental irona and 2800 µg (2.8 mg) of folic acid once weekly is recommended for pregnant women to improve maternal and neonatal outcomes if daily iron is not acceptable due to side- effects, and in populations with an anaemia prevalence among pregnant women of less than 20%. (Context-specific recommendation)

Remarks • This recommendation supersedes the previous WHO recommendation in the 2012 Guideline: intermittent iron and folic acid supplementation in non-anaemic pregnant women (55) and should be considered alongside Recommendation A.1.1. • In general, anaemia prevalence of less than 20% is classified as a mild public health problem (33). • Before commencing intermittent iron supplementation, accurate measurement of maternal blood Hb concentrations is needed to confirm the absence of anaemia. Therefore, this recommendation may require a strong health system to facilitate accurate Hb measurement and to monitor anaemia status throughout pregnancy. • If a woman is diagnosed with anaemia (Hb < 110 g/L) during ANC, she should be given 120 mg of elemental iron and 400 µg (0.4 mg) of folic acid daily until her Hb concentration rises to normal (Hb 110 g/L or higher) (34, 51). Thereafter, she can continue with the standard daily antenatal iron and folic acid dose (or the intermittent regimen if daily iron is not acceptable due to side-effects) to prevent recurrence of anaemia. • Stakeholders may need to consider ways of reminding pregnant women to take their supplements on an intermittent basis and of assisting them to manage associated side-effects. a The equivalent of 120 mg of elemental iron is 600 mg of ferrous sulfate hepahydrate, 360 mg of ferrous fumarate or 1000 mg of ferrous gluconate.

A.3: Calcium supplements

RECOMMENDATION A.3: In populations with low dietary calcium intake, daily calcium supplementation (1.5–2.0 g oral elemental calcium) is recommended for pregnant women to reduce the risk of pre-eclampsia. (Context-specific recommendation)

Remarks • This recommendation is consistent with the 2011 WHO recommendations for prevention and treatment of pre-eclampsia and eclampsia (57) (strong recommendation, moderate-quality evidence) and supersedes the WHO recommendation found in the 2013 Guideline: calcium supplementation in pregnant women (38). • Dietary counselling of pregnant women should promote adequate calcium intake through locally available, calcium-rich foods. • Dividing the dose of calcium may improve acceptability. The suggested scheme for calcium supplementation is 1.5–2 g daily, with the total dose divided into three doses, preferably taken at mealtimes. • Negative interactions between iron and calcium supplements may occur. Therefore, the two nutrients should preferably be administered several hours apart rather than concomitantly (38). • As there is no clear evidence on the timing of initiation of calcium supplementation, stakeholders may wish to commence supplementation at the first ANC visit, given the possibility of compliance issues. • To reach the most vulnerable populations and ensure a timely and continuous supply of supplements, stakeholders may wish to consider task shifting the provision of calcium supplementation in community settings with poor access to health-care professionals (see Recommendation E.6.1, in section E: Health systems interventions to improve the utilization and quality of ANC). • The implementation and impact of this recommendation should be monitored at the health service, regional and country levels, based on clearly defined criteria and indicators associated with locally agreed targets. Successes and failures should be evaluated to inform integration of this recommendation into the ANC package. • Further WHO guidance on prevention and treatment of pre-eclampsia and eclampsia is available in the 2011 WHO recommendations (57), available at: http://apps.who.int/iris/ bitstream/10665/44703/1/9789241548335_eng.pdf

A.4: Vitamin A supplements

RECOMMENDATION A.4: Vitamin A supplementation is only recommended for pregnant women in areas where vitamin A deficiency is a severe public health problem, to prevent night blindness. (Context-specific recommendation)

Remarks • This recommendation supersedes the previous WHO recommendation found in the 2011 Guideline: vitamin A supplementation in pregnant women (60). • Vitamin A is not recommended to improve maternal and perinatal outcomes. • Vitamin A deficiency is a severe public health problem if 5% or more of women in a population have a history of night blindness in their most recent pregnancy in the previous 3–5 years that ended in a live birth, or if 20% or more of pregnant women have a serum retinol level below 0.70 µmol/L (61). Determination of vitamin A deficiency as a public health problem involves estimating the prevalence of deficiency in a population by using specific biochemical and clinical indicators of vitamin A status. • Pregnant women should be encouraged to receive adequate nutrition, which is best achieved through consumption of a healthy, balanced diet, and to refer to WHO guidance on healthy eating (41). • In areas where supplementation is indicated for vitamin A deficiency, it can be given daily or weekly. Existing WHO guidance suggests a dose of up to 10 000 IU vitamin A per day, or a weekly dose of up to 25 000 IU (60). • A single dose of a vitamin A supplement greater than 25 000 IU is not recommended as its safety is uncertain. Furthermore, a single dose of a vitamin A supplement greater than 25 000 IU might be teratogenic if consumed between day 15 and day 60 from conception (60). • There is no demonstrated benefit from taking vitamin A supplements in populations where habitual daily vitamin A intakes exceed 8000 IU or 2400 µg, and the potential risk of adverse events increases with higher intakes (above 10 000 IU) if supplements are routinely taken by people in these populations (62).

RECOMMENDATION A.5: Zinc supplementation for pregnant women is only recommended in the context of rigorous research. (Context-specific recommendation – research)

Remarks • Many of the included studies were at risk of bias, which influenced the certainty of the review evidence on the effects of zinc supplementation. • The low-certainty evidence that zinc supplementation may reduce preterm birth warrants further investigation, as do the other outcomes for which the evidence is very uncertain (e.g. perinatal mortality, neonatal sepsis), particularly in zinc-deficient populations with no food fortification strategy in place. Further research should aim to clarify to what extent zinc supplementation competes with iron and/or calcium antenatal supplements for absorption. The GDG considered that food fortification may be a more cost–effective strategy and that more evidence is needed on the cost–effectiveness of food fortification strategies.

A.8: Vitamin E and C supplements

RECOMMENDATION A.8: Vitamin E and C supplementation is not recommended for pregnant women to improve maternal and perinatal outcomes. (Not recommended)

Remarks • The GDG noted that vitamin E and C combined supplements were evaluated mainly in the context of preventing pre-eclampsia. Vitamin C is important for improving the bioavailability of oral iron, but this was not considered within the context of the Cochrane reviews. In addition, low-certainty evidence on vitamin C alone suggests that it may prevent prelabour rupture of membranes (PROM). Therefore, the GDG agreed that future research should consider vitamin C supplements separately from vitamin E and C supplements. • Pregnant women should be encouraged to receive adequate nutrition, which is best achieved through consumption of a healthy, balanced diet, and to refer to guidelines on healthy eating (41). It is relatively easy to consume sufficient quantities of vitamin C from food sources.

Summary of evidence and considerations Fetal and neonatal outcomes High-certainty evidence indicates that vitamin E and Effects of vitamin E and C supplements C supplementation does not have an important effect compared with no vitamin E and C supplements on SGA (11 trials, 20 202 women; RR: 0.98, 95% CI: (EB Table A.8) 0.91–1.06).

B.1.1: Anaemia

RECOMMENDATION B.1.1: Full blood count testing is the recommended method for diagnosing anaemia during pregnancy. In settings where full blood count testing is not available, on- site haemoglobin testing with a haemoglobinometer is recommended over the use of the haemoglobin colour scale as the method for diagnosing anaemia in pregnancy. (Context-specific recommendation)

Remarks • The GDG agreed that the high recurrent costs of Hb testing with haemoglobinometers might reduce the feasibility of this method in some low-resource settings, in which case the WHO haemoglobin colour scale method may be used. • Other low-technology on-site methods for detecting anaemia need development and/or investigation.

Summary of evidence and considerations Moderate-certainty evidence shows that the sensitivity and specificity of the haemoglobinometer Test accuracy of on-site Hb testing with test in detecting anaemia (Hb < 110 g/L) are haemoglobinometer and haemoglobin colour approximately 0.85 (95% CI: 0.79–0.90) and scale (HCS) methods to detect anaemia (EB 0.80 (95% CI: 0.76–0.83), respectively, while the Table B.1.1) sensitivity and specificity of the HCS method are The evidence was derived from a test accuracy lower at approximately 0.75 (95% CI: 0.71–0.80) and review conducted to support the ANC guideline 0.47 (95% CI: 0.41–0.53), respectively.

RECOMMENDATION B.1.2: Midstream urine culture is the recommended method for diagnosing asymptomatic bacteriuria (ASB) in pregnancy. In settings where urine culture is not available, on-site midstream urine Gram-staining is recommended over the use of dipstick tests as the method for diagnosing ASB in pregnancy. (Context-specific recommendation)

Remarks • This recommendation should be considered alongside Recommendation C.1 on ASB treatment (see section C: Preventive measures). • The GDG agreed that the higher resource costs associated with Gram stain testing might reduce the feasibility of this method in low-resource settings, in which case, dipstick tests may be used. • The GDG agreed that ASB is a priority research topic, given its association with preterm birth and the uncertainty around urine testing and treatment in settings with different levels of ASB prevalence. Specifically, studies are needed that compare on-site testing and treatment versus testing plus confirmation of test with treatment on confirmatory culture, to explore health and other relevant outcomes, including acceptability, feasibility and antimicrobial resistance. In addition, better on-site tests need to be developed to improve accuracy and feasibility of testing and to reduce overtreatment of ASB. Research is also needed to determine the prevalence of ASB at which targeted testing and treatment rather than universal testing and treatment might be effective.

Summary of evidence and considerations Additional considerations nnA high level of accuracy in detecting ASB is Test accuracy of on-site urine Gram staining and important to avoid treating women unnecessarily, dipsticks to detect ASB (EB Table B.1.2) particularly in view of increasing antimicrobial The evidence was derived from a test accuracy resistance. Based on the uncertain evidence above, review of on-site urine tests conducted to support and assuming a prevalence of ASB of 9%, there the ANC guideline (88). Four studies (1904 pregnant would be 18 and 118 false-positive tests per 1000 women) contributed data on urine Gram staining and women tested with Gram stain and dipstick tests, eight studies (5690 pregnant women) contributed respectively. This suggests that, in settings where data on urine dipsticks. Most of the studies were pregnant women are treated for ASB, dipstick conducted in LMICs.

RECOMMENDATION B.1.3: Clinical enquiry about the possibility of intimate partner violence (IPV) should be strongly considered at antenatal care visits when assessing conditions that may be caused or complicated by IPV in order to improve clinical diagnosis and subsequent care, where there is the capacity to provide a supportive response (including referral where appropriate) and where the WHO minimum requirements are met.a (Context-specific recommendation)

Remarks • This recommendation is consistent with the 2013 publication Responding to intimate partner violence and sexual violence against women: WHO clinical and policy guidelines (86). The evidence on clinical enquiry was indirect (strong recommendation) and the evidence on universal screening was judged as being of low to moderate quality (conditional recommendation). • “Universal screening” or “routine enquiry” (i.e. asking all women at all health-care encounters) about IPV is not recommended. However, the WHO guidelines identify ANC as a setting where routine enquiry could be implemented if providers are well trained on a first-line response and minimum requirements are met (86). • Examples of conditions during pregnancy that may be caused or complicated by IPV include (86): –– traumatic injury, particularly if repeated and with vague or implausible explanations; –– intrusive partner or husband present at consultations; –– adverse reproductive outcomes, including multiple unintended pregnancies and/or terminations, delay in seeking ANC, adverse birth outcomes, repeated STIs; –– unexplained or repeated genitourinary symptoms; –– symptoms of depression and anxiety; –– alcohol and other substance use; –– self-harm, suicidality, symptoms of depression and anxiety. • The GDG agreed that, despite a paucity of evidence, it was important to make a recommendation due to the high prevalence and importance of IPV. ANC provides an opportunity to enquire about IPV among women for whom barriers to accessing health care may exist, and also allows for the possibility for follow-up during ANC with appropriate supportive interventions, such as counselling and empowerment interventions. However, the evidence on benefits and potential harms of clinical enquiry and subsequent interventions is lacking or uncertain. • A minimum condition for health-care providers to ask women about violence is that it must be safe to do so (i.e. the partner is not present) and that identification of IPV is followed by an appropriate response. In addition, providers must be trained to ask questions in the correct way and to respond appropriately to women who disclose violence (86). • Research on IPV is needed to answer the following questions: –– Which are the most effective strategies for identifying, preventing and managing IPV in pregnancy? –– Does asking routinely about violence impact on ANC attendance? –– Can interventions targeted at partners of pregnant women prevent IPV? • Detailed guidance on responding to IPV and sexual violence against women can be found in the 2013 WHO clinical and policy guidelines (86), available at: http://www.who.int/reproductivehealth/ publications/violence/9789241548595/en/ a Minimum requirements are: a protocol/standard operating procedure; training on how to ask about IPV, and on how to provide the minimum response or beyond; private setting; confidentiality ensured; system for referral in place; and time to allow for appropriate disclosure.

Related recommendations from this guideline include the following: –– Health-care providers should routinely offer advice and psychosocial interventions for tobacco cessation to all pregnant women who are either current tobacco users or recent tobacco quitters (strong recommendation based on moderate quality evidence). –– All health-care facilities should be smoke-free to protect the health of all staff, patients and visitors, including pregnant women (strong recommendation based on low-quality evidence). –– Health-care providers should provide pregnant women, their partners and other household members with advice and information about the risks of second-hand smoke (SHS) exposure from all forms of smoked tobacco, as well as strategies to reduce SHS in the home (strong recommendation based on low- quality evidence). –– Health-care providers should, wherever possible, engage directly with partners and other household members to inform them of all the risks of SHS exposure to pregnant women from all forms of tobacco, and to promote reduction of exposure and offer smoking cessation support (strong recommendation based on low-quality evidence). • Further guidance on strategies to prevent and manage tobacco use and SHS exposure can be found in the 2013 WHO recommendations (96), available at: http://www.who.int/tobacco/publications/pregnancy/ guidelinestobaccosmokeexposure/en/

(97). B.1.7: Human immunodeficiency virus (HIV) and syphilis

RECOMMENDATION B.1.7: In high-prevalence settings,a provider-initiated testing and counselling (PITC) for HIV should be considered a routine component of the package of care for pregnancy women in all antenatal care settings. In low-prevalence settings, PITC can be considered for pregnant women in antenatal care settings as a key component of the effort to eliminate mother-to-child transmission of HIV, and to integrate HIV testing with syphilis, viral or other key tests, as relevant to the setting, and to strengthen the underlying maternal and child health systems. (Recommended)

Remarks • This recommendation has been integrated from the 2015 WHO Consolidated guidelines on HIV testing services (98) (the strength of the recommendation and the quality of the evidence were not stated). • PITC denotes an HIV testing service that is routinely offered in a health-care facility and includes providing pre-test information and obtaining consent, with the option for individuals to decline testing. PITC has proved highly acceptable and has increased the uptake of HIV testing in LMICs (98). • The availability of HIV testing at ANC services is responsible for the high level of knowledge of HIV status among women in many countries, which has allowed women and infants to benefit from ART. • WHO recommends that ART should be initiated in all pregnant women diagnosed with HIV at any CD4 count and continued lifelong (99). This recommendation is based on evidence that shows that providing ART to all pregnant and breastfeeding women living with HIV improves individual health outcomes, prevents mother-to-child transmission of HIV, and prevents horizontal transmission of HIV from the mother to an uninfected sexual partner. • Other recommendations relevant to ANC services from the Consolidated guidelines on HIV testing services include the following (98): –– On disclosure: Initiatives should be put in place to enforce privacy protection and institute policy, laws and norms that prevent discrimination and promote tolerance and acceptance of people living with HIV. This can help create environments where disclosure of HIV status is easier (strong recommendation, low-quality evidence). –– On retesting: In settings with a generalized HIV epidemic:b Retest all HIV-negative pregnant women in the third trimester, during labour or postpartum because of the high risk of acquiring HIV infection during pregnancy (strength of recommendation and quality of evidence not stated). –– On retesting: In settings with a concentrated HIV epidemic:c Retest HIV-negative pregnant women who are in a serodiscordant couple or from a key population groupd (strength of recommendation and quality of evidence not stated). –– On retesting before ART initiation: National programmes should retest all people newly and previously diagnosed with HIV before they enrol in care and initiate ART (strength of recommendation and quality of evidence not stated). –– On testing strategies: In settings with greater than 5% HIV prevalence in the population being tested, a diagnosis of HIV-positive should be issued to people with two sequential reactive tests. In settings with less than 5% HIV prevalence in the population being tested, a diagnosis of HIV-positive should be issued to people with three sequential reactive tests (strength of recommendation and quality of evidence not stated). –– On task shifting: Lay providers who are trained and supervised can independently conduct safe and effective HIV testing using rapid diagnostic tests (strong recommendation, moderate-quality evidence). • Further guidance on HIV testing can be found in the 2015 WHO guidelines (98), available at: http://www.who.int/hiv/pub/guidelines/hiv-testing-services/en/ • In addition, the 2015 Guideline on when to start antiretroviral therapy and on pre-exposure prophylaxis for HIV (99) is available at: http://www.who.int/hiv/pub/guidelines/earlyrelease-arv/en/ • To prevent mother-to-child transmission of syphilis, all pregnant women should be screened for syphilis at the first ANC visit in the first trimester and again in the third trimester of pregnancy.

RECOMMENDATION B.2.3: Routine antenatal cardiotocography is not recommended for pregnant women to improve maternal and perinatal outcomes. (Not recommended)

Remarks • CTG is the continuous recording of the fetal heart rate and uterine contractions obtained via an ultrasound transducer placed on the mother’s abdomen. • There is currently no evidence on effects or other considerations that supports the use of antenatal (prelabour) CTG as part of routine ANC. • A lack of evidence of benefits associated with CTG in high-risk pregnancies suggests that the evaluation of antenatal CTG in healthy pregnant women is not a research priority.

RECOMMENDATION B.2.5: Routine Doppler ultrasound examination is not recommended for pregnant women to improve maternal and perinatal outcomes. (Not recommended)

Remarks • The GDG noted that the evidence base for the use of Doppler ultrasound of fetal blood vessels in high- risk pregnancy is already established. • The GDG agreed that the value of a single Doppler ultrasound examination of fetal blood vessels for all pregnant women in the third trimester needs rigorous evaluation, particularly in LMIC settings. Future trials should be designed to evaluate the effect of a single Doppler ultrasound on preventable perinatal deaths.

RECOMMENDATION C.7: Oral pre-exposure prophylaxis (PrEP) containing tenofovir disoproxil fumarate (TDF) should be offered as an additional prevention choice for pregnant women at substantial risk of HIV infection as part of combination prevention approaches. (Context-specific recommendation)

Remarks • This recommendation has been integrated from the WHO guideline on when to start antiretroviral therapy and on pre-exposure prophylaxis for HIV (2015), where it is considered to be a strong recommendation based on high-quality evidence (99). The evidence and further guidance related to the recommendation can be found in this guideline. • “Substantial risk” is provisionally defined as HIV incidence greater than 3 per 100 person-years in the absence of PrEP, but individual risk varies within this group depending on individual behaviour and the characteristics of sexual partners. Local epidemiological evidence concerning risk factors and HIV incidence should be used to inform implementation. • Thresholds for offering PrEP may vary depending on a variety of considerations, including resources, feasibility and demand. • The level of protection is strongly correlated with adherence. • Detailed evidence and guidance related to this recommendation can be found in the 2015 guideline (99), available at: http://www.who.int/hiv/pub/guidelines/earlyrelease-arv/en/

D.2: Interventions for heartburn

RECOMMENDATION D.2: Advice on diet and lifestyle is recommended to prevent and relieve heartburn in pregnancy. Antacid preparations can be offered to women with troublesome symptoms that are not relieved by lifestyle modification. (Recommended)

Remarks • Lifestyle advice to prevent and relieve symptoms of heartburn includes avoidance of large, fatty meals and alcohol, cessation of smoking, and raising the head of the bed to sleep. • The GDG agreed that antacids, such as magnesium carbonate and aluminium hydroxide preparations, are probably unlikely to cause harm in recommended dosages. • There is no evidence that preparations containing more than one antacid are better than simpler preparations. • Antacids may impair absorption of other drugs (164), and therefore should not be taken within two hours of iron and folic acid supplements.

D.6: Interventions for varicose veins and oedema

RECOMMENDATION D.6: Non-pharmacological options, such as compression stockings, leg elevation and water immersion, can be used for the management of varicose veins and oedema in pregnancy based on a woman’s preferences and available options. (Recommended)

Remarks • Women should be informed that symptoms associated with varicose veins may worsen as pregnancy progresses but that most women will experience some improvement within a few months of giving birth. • Rest, leg elevation and water immersion are low-cost interventions that are unlikely to be harmful.

Thus, the MLCC model exists women are given their own case notes (or home- within a multidisciplinary network in which based records) to carry during pregnancy. Case consultation and referral to other care providers notes may be held in paper (e.g. card, journal, occurs when necessary. The MLCC model is handbook) or electronic formats (e.g. memory usually aimed at providing care to healthy women stick), and women are expected to take them with uncomplicated pregnancies. along to all health visits. If women then move, or are referred from one facility to another, and in the nnGroup ANC: ANC conventionally takes the form case of complications where immediate access of a one-on-one consultation between a pregnant to medical records is not always possible, the woman and her health-care provider. However, practice of women-held case notes may improve group ANC integrates the usual individual the availability of women’s medical records pregnancy health assessment with tailored group (168). Women-held case notes might also be an educational activities and peer support, with effective tool to improve health awareness and the aim of motivating behaviour change among client–provider communication (169). Inadequate pregnant women, improving pregnancy outcomes, infrastructure and resources often hamper efficient and increasing women’s satisfaction (174). The record-keeping, therefore, case notes may be intervention typically involves self-assessment less likely to get lost when held personally. In activities (e.g. blood pressure measurement), addition, the practice may facilitate more accurate group education with facilitated discussion, and

RECOMMENDATION E.1: It is recommended that each pregnant woman carries her own case notes during pregnancy to improve continuity, quality of care and her pregnancy experience. (Recommended)

Remarks • The GDG noted that women-held case notes are widely used and are often the only medical records available in various LMIC settings. • The GDG agreed that the benefits of women-held case notes outweigh the disadvantages. However, careful consideration should be given as to what personal information it is necessary to include in the case notes, to avoid stigma and discrimination in certain settings. In addition, health-system planners should ensure that admission to hospitals or other health-care facilities do not depend on women presenting their case notes. • Health-system planners should consider which form the women-held case notes should take (electronic or paper-based), whether whole sets of case notes will be held by women or only specific parts of them, and how copies will be kept by health-care facilities. • For paper-based systems, health-system planners also need to ensure that case notes are durable and transportable. Health systems that give women access to their case notes through electronic systems need to ensure that all pregnant women have access to the appropriate technology and that attention is paid to data security. • Health-system planners should ensure that the contents of the case notes are accessible to all pregnant women through the use of appropriate, local languages and appropriate reading levels.

E.2: Midwife-led continuity of care (MLCC)

RECOMMENDATION E.2: Midwife-led continuity-of-care models, in which a known midwife or small group of known midwives supports a woman throughout the antenatal, intrapartum and postnatal continuum, are recommended for pregnant women in settings with well functioning midwifery programmes. (Context-specific recommendation)

Remarks • MLCC models are models of care in which a known and trusted midwife (caseload midwifery), or small group of known midwives (team midwifery), supports a woman throughout the antenatal, intrapartum and postnatal period, to facilitate a healthy pregnancy and childbirth, and healthy parenting practices. • MLCC models are complex interventions and it is unclear whether the pathway of influence producing these positive effects is the continuity of care, the midwifery philosophy of care or both. The midwifery philosophy inherent in MLCC models may or may not be enacted in standard midwife practice in other models of care. • Policy-makers in settings without well functioning midwife programmes should consider implementing this model only after successfully scaling up of the number and quality of practising midwives. In addition, stakeholders may wish to consider ways of providing continuous care through other care providers, because women value continuity of care. • The panel noted that with this model of care it is important to monitor resource use, and provider burnout and workload, to determine whether caseload or team care models are more sustainable in individual settings. • MLCC requires that well trained midwives are available in sufficient numbers for each woman to see one or only a small group of midwives throughout pregnancy and during childbirth. This model may therefore require a shift in resources to ensure that the health system has access to a sufficient number of midwives with reasonable caseloads. • The introduction of MLCC may lead to a shift in the roles and responsibilities of midwives as well as other health-care professionals who have previously been responsible for antenatal and postnatal care. Where this is the case, implementation is likely to be more effective if all relevant stakeholders are consulted and human resources departments are involved. In some settings, government-level consultation with professional organizations could also aid implementation processes. • The need for additional one-off or continuing training and education should be assessed, and should be provided where necessary.

E.3: Group antenatal care

RECOMMENDATION E.3: Group antenatal care provided by qualified health-care professionals may be offered as an alternative to individual antenatal care for pregnant women in the context of rigorous research, depending on a woman’s preferences and provided that the infrastructure and resources for delivery of group antenatal care are available. (Context-specific recommendation – research)

Remarks • With the group ANC model, the first visit for all pregnant women is an individual visit. Then at subsequent visits, the usual individual pregnancy health assessment, held in a private examination area, is integrated into a group ANC session, with facilitated educational activities and peer support. • Health-care facilities need to be seeing sufficient numbers of pregnant women, as allocation to groups is ideally performed according to gestational age. • Health-care providers need to have appropriate facilities to deal with group sessions, including access to large, well ventilated rooms or sheltered spaces with adequate seating. A private space should be available for examinations, and opportunities should be given for private conversations. • Group ANC may take longer than individual ANC, and this may pose practical problems for some women in terms of work and childcare. Health-care providers should be able to offer a variety of time slots for group sessions (morning, afternoon, evening) and should consider making individual care available as well. • The GDG noted that group ANC may have acceptability and feasibility issues in settings where perceived differences keep people apart, e.g. women from different castes in India may not wish to be in a group together. • Group ANC studies are under way in Nepal, Uganda and five other low-income countries, and the GDG was informed by a GDG member that some of these studies are due to report soon. Core outcomes of studies of group ANC should include maternal and perinatal health outcomes, coverage, and women's and providers' experiences.

E.4: Community-based interventions to improve communication and support

E.4.1: Facilitated participatory learning and action (PLA) cycles with women’s groups

RECOMMENDATION E.4.1: The implementation of community mobilization through facilitated participatory learning and action (PLA) cycles with women’s groups is recommended to improve maternal and newborn health, particularly in rural settings with low access to health services. Participatory women’s groups represent an opportunity for women to discuss their needs during pregnancy, including barriers to reaching care, and to increase support to pregnant women. (Context-specific recommendation)

Remarks • Part of this recommendation was integrated from WHO recommendations on community mobilization through facilitated participatory learning and action cycles with women’s groups for maternal and newborn health (2014) (183). • The pathways of influence of this multifaceted, context-specific intervention on maternal and newborn outcomes are difficult to assess. Women meeting to identify their needs and seek solutions plays an important role; mechanisms related to additional activities that are organized based on the solutions identified at the meetings may also play a role. • Detailed information and guidance related to the recommendation, including important implementation considerations, can be found in the 2014 WHO recommendations on PLA cycles (183), available at: http://www.who.int/maternal_child_adolescent/documents/community-mobilization-maternal- newborn/en/

RECOMMENDATION E.4.2: Packages of interventions that include household and community mobilization and antenatal home visits are recommended to improve antenatal care utilization and perinatal health outcomes, particularly in rural settings with low access to health services. (Context-specific recommendation)

Remarks • The GDG agreed that the extent to which these packages improve communication and support for pregnant women is not clear. • As a stand-alone intervention, the evidence does not support the use of antenatal home visits by lay health workers during pregnancy to improve ANC utilization health outcomes. While the quality and effectiveness of communication during home visits, and the extent to which they increase support for women, is not clear, antenatal home visits may be helpful in ensuring continuity of care across the antenatal, intrapartum and postnatal periods and in promoting other healthy behaviour. • Stakeholders need to be clear that antenatal home visits by lay health workers do not replace ANC visits. • Stakeholders should implement health system strengthening interventions alongside these community- based interventions. • Health-care providers need initial and ongoing training in communication with women and their partners. For women’s groups and community mobilization, providers also need training on group facilitation, in the convening of public meetings and in other methods of communication. • Information for women and community members should be provided in languages and formats accessible to them and programme planners need to ensure that health-care providers/facilitators have reliable supplies of appropriate information materials. • Programme planners should be aware of the potential for additional costs associated with home visits and community mobilization initiatives, including the potential need for extra staff and travel expenses. • When considering the use of antenatal home visits, women’s groups, partner involvement or community mobilization, programme planners need to ensure that these can be implemented in a way that respects and facilitates women’s needs for privacy as well as their choices and their autonomy in decision-making. By offering pregnant women a range of opportunities for contact, communication and support, their individual preferences and circumstances should also be addressed. • Further research is needed on the acceptability and feasibility of mixed-gender communication, the optimal methods for community mobilization, the best model for integration with health systems, continuity elements of home visits, and the mechanisms of effect of these interventions.

Recommendation 1: Birth preparedness and complication readiness interventions are recommended to increase the use of skilled care at birth and to increase the timely use of facility care for obstetric and newborn complications. (Strong recommendation, very low-quality evidence.)

Recommendation 2: Interventions to promote the involvement of men during pregnancy, childbirth and after birth are recommended to facilitate and support improved self-care of women, improved home care practices for women and newborns, and improved use of skilled care during pregnancy, childbirth and the postnatal period for women and newborns. (Strong recommendation, very low-quality evidence.) These interventions are recommended provided that they are implemented in a way that respects, promotes and facilitates women’s choices and their autonomy in decision-making, and supports women in taking care of themselves and their newborns. In order to ensure this, rigorous monitoring and evaluation of implementation is recommended.

Recommendation 3 on interventions to promote awareness of human, sexual and reproductive rights and the right to access quality skilled care: Because of the paucity of evidence available, additional research is recommended. The GDG supports, as a matter of principle, the importance for MNH programmes to inform women about their right to health and to access quality skilled care, and to continue to empower them to access such care.

Recommendation 6 on partnership with traditional birth attendants (TBAs): Where TBAs remain the main providers of care at birth, dialogue with TBAs, women, families, communities and service providers is recommended in order to define and agree on alternative roles for TBAs, recognizing the important role they can play in supporting the health of women and newborns. (Strong recommendation, very low-quality evidence.)

Recommendation 7: Ongoing dialogue with communities is recommended as an essential component in defining the characteristics of culturally appropriate, quality maternity care services that address the needs of women and newborns and incorporate their cultural preferences. Mechanisms that ensure women’s voices are meaningfully included in these dialogues are also recommended. (Strong recommendation, very low-quality evidence.)

Recommendation 11: Community participation in quality-improvement processes for maternity care services is recommended to improve quality of care from the perspectives of women, communities and health-care providers. Communities should be involved in jointly defining and assessing quality. Mechanisms that ensure women’s voices are meaningfully included are also recommended. (Strong recommendation, very low-quality evidence.)

Recommendation 12: Community participation in programme planning, implementation and monitoring is recommended to improve use of skilled care during pregnancy, childbirth and the postnatal period for women and newborns, increase the timely use of facility care for obstetric and newborn complications and improve maternal and newborn health. Mechanisms that ensure women’s voices are meaningfully included are also recommended. (Strong recommendation, very low-quality evidence.)

RECOMMENDATION E.5.2: Task shifting the distribution of recommended nutritional supplements and intermittent preventive treatment in pregnancy (IPTp) for malaria prevention to a broad range of cadres, including auxiliary nurses, nurses, midwives and doctors is recommended. (Recommended)

Remarks • Recommendations E.5.1 and E.5.2 have been adapted and integrated from Optimizing health worker roles to improve access to key maternal and newborn health interventions through task shifting (OptimizeMNH) (2012) (201). • The GDG noted that, while task shifting has an important role to play in allowing flexibility in health-care delivery in low-resource settings, policy-makers need to work towards midwife-led care for all women. • Lay health workers need to be recognized and integrated into the system, and not be working alone, i.e. task shifting needs to occur within a team approach. • The mandate of all health workers involved in task shifting programmes needs to be clear. • In a separate guideline on HIV testing services (98), WHO recommends that lay providers who are trained and supervised can independently conduct safe and effective HIV testing using rapid tests (see Recommendation B.1.8). • The GDG noted that it may be feasible to task shift antenatal ultrasound to midwives with the appropriate training, staffing, mentoring and referral systems in place. • Further research is needed on the mechanism of effect of MLCC and whether continuity of care can be task shifted. • Further information on this recommendation can be found in the OptimizeMNH guideline (201), available at: http://www.who.int/reproductivehealth/publications/maternal_perinatal_health/978924504843/en/ a Including promotion of the following: care-seeking behaviour and ANC utilization; birth preparedness and complication readiness; sleeping under insecticide- treated bednets; skilled care for childbirth; companionship in labour and childbirth; nutritional advice; nutritional supplements; HIV testing during pregnancy; exclusive breastfeeding; postnatal care and family planning; immunization according to national guidelines.

RECOMMENDATION E.7: Antenatal care models with a minimum of eight contacts are recommended to reduce perinatal mortality and improve women’s experience of care. (Recommended)

Remarks • The GDG stresses that the four-visit focused ANC (FANC) model does not offer women adequate contact with health-care practitioners and is no longer recommended. With the FANC model, the first ANC visit occurs before 12 weeks of pregnancy, the second around 26 weeks, the third around 32 weeks, and the fourth between 36 and 38 weeks of gestation. Thereafter, women are advised to return to ANC at 41 weeks of gestation or sooner if they experience danger signs. Each ANC visit involves specific goals aimed at improving triage and timely referral of high-risk women and includes educational components (12). However, up-to-date evidence shows that the FANC model, which was developed in the 1990s, is probably associated with more perinatal deaths than models that comprise at least eight ANC visits. Furthermore, evidence suggests that more ANC visits, irrespective of the resource setting, is probably associated with greater maternal satisfaction than less ANC visits. • The GDG prefers the word “contact” to “visit”, as it implies an active connection between a pregnant woman and a health-care provider that is not implicit with the word “visit”. In terms of the operationalization of this recommendation, “contact” can be adapted to local contexts through community outreach programmes and lay health worker involvement. • The decision regarding the number of contacts with a health system was also influenced by the following: –– evidence supporting improving safety during pregnancy through increased frequency of maternal and fetal assessment to detect problems; –– evidence supporting improving health system communication and support around pregnancy for women and families; –– evidence from HIC studies indicating no important differences in maternal and perinatal health outcomes between ANC models that included at least eight contacts and ANC models that included more (11–15) contacts (203); –– evidence indicating that more contact between pregnant women and knowledgeable, supportive and respectful health-care practitioners is more likely to lead to a positive pregnancy experience. • Implementation considerations related to this recommendation and the mapping of guideline recommendations to ANC contacts are presented in Chapter 4: Implementation of the ANC guideline and recommendations.

Summary of evidence and considerations RCTs involving more than 50 000 women contributed data.

Implementation of the ANC guideline and recommendations: introducing the 2016 WHO ANC model

The ultimate goal of this guideline and its local context, to allow flexibility in the delivery of the recommendations is to improve the quality recommended interventions. Different to the FANC of ANC and to improve maternal, fetal and model, an additional contact is now recommended newborn outcomes related to ANC. These ANC at 20 weeks of gestation, and an additional three recommendations need to be deliverable within an contacts are recommended in the third trimester appropriate model of care that can be adapted to (defined as the period from 28 weeks of gestation different countries, local contexts and the individual up to delivery), since this represents the period of woman. With the contributions of the members of greatest antenatal risk for mother and baby (see the Guideline Development Group (GDG), WHO Box 5). At these third-trimester contacts, ANC reviewed existing models of delivering ANC with providers should aim to reduce preventable morbidity full consideration of the range of interventions and mortality through systematic monitoring of recommended within this guideline (Chapter 3). maternal and fetal well-being, particularly in relation Recommendation E.7 states that “Antenatal care to hypertensive disorders and other complications models with a minimum of eight contacts are that may be asymptomatic but detectable during this recommended to reduce perinatal mortality and critical period. improve women’s experience of care”; taking this as a foundation, the GDG reviewed how ANC should Box 5: Comparing ANC schedules be delivered in terms of both the timing and content of each of the ANC contacts, and arrived at a new WHO FANC 2016 WHO ANC model – the 2016 WHO ANC model – which replaces model model the previous four-visit focused ANC (FANC) model. For the purpose of developing this new ANC model, First trimester the ANC guideline recommendations were mapped to Visit 1: 8–12 weeks Contact 1: up to 12 weeks the eight contacts based on the evidence supporting Second trimester each recommendation and the optimal timing of delivery of the recommended interventions to achieve Contact 2: 20 weeks Visit 2: 24–26 weeks Contact 3: 26 weeks maximal impact. Third trimester

The 2016 WHO ANC model recommends a minimum Visit 3: 32 weeks Contact 4: 30 weeks of eight ANC contacts, with the first contact Contact 5: 34 weeks scheduled to take place in the first trimester (up to Visit 4: 36–38 weeks Contact 6: 36 weeks 12 weeks of gestation), two contacts scheduled in the Contact 7: 38 weeks Contact 8: 40 weeks second trimester (at 20 and 26 weeks of gestation) and five contacts scheduled in the third trimester (at Return for delivery at 41 weeks if not given birth. 30, 34, 36, 38 and 40 weeks). Within this model, the word “contact” has been used instead of “visit”, as it implies an active connection between a pregnant woman and a health-care provider that is not implicit If the quality of ANC is poor and women’s experience with the word “visit”. It should be noted that the list of it is negative, the evidence shows that women of interventions to be delivered at each contact and will not attend ANC, irrespective of the number of details about where they are delivered and by whom recommended contacts in the ANC model. Thus, (see Table 2) are not meant to be prescriptive but, the overarching aim of the 2016 WHO ANC model rather, adaptable to the individual woman and the is to provide pregnant women with respectful,

y. This recommendation is consistent with the 2006 WHO guideline on Maternal immunization against tetanus (134). The dosing schedule depends on the previous tetanus vaccination exposure; please refer to Recommendation C.5 for details. z. Integrated from the 2015 WHO publication Guidelines for the treatment of malaria, which also states: “WHO recommends that, in areas of moderate-to-high malaria transmission of Africa, IPTp-SP be given to all pregnant women at each scheduled antenatal care visit, starting as early as possible in the second trimester, provided that the doses of SP are given at least 1 month apart. WHO recommends a package of interventions for preventing malaria during pregnancy, which includes promotion and use of insecticide-treated nets, as well as IPTp-SP” (153). To ensure that pregnant women in endemic areas start IPTp-SP as early as possible in the second trimester, policy-makers should ensure health system contact with women at 13 weeks of gestation. aa. Integrated from the 2015 WHO publication Guideline on when to start antiretroviral therapy and on pre-exposure prophylaxis for HIV (99). Substantial risk of HIV infection is defined by an incidence of HIV infection in the absence of PrEP that is sufficiently high (> 3% incidence) to make offering PrEP potentially cost-saving (or cost–effective).

Box 6: Considerations for the adoption, scale-up and implementation of the 2016 WHO ANC model

Health policy considerations for adoption and scale-up of the model nnThere needs to be a firm government commitment to scale up implementation of ANC services to achieve national coverage at health-care facilitates; national support must be secured for the whole package rather than for specific components, to avoid fragmentation of services. nnIn low-income countries, donors may play a significant role in scaling up the implementation of the model. Sponsoring mechanisms that support domestically driven processes to scale up the whole model are more likely to be helpful than mechanisms that support only a part of the package. nnTo set the policy agenda, to secure broad anchoring and to ensure progress in policy formulation and decision-making, stakeholders should be targeted among both elected and bureaucratic officials. In addition, representatives of training facilities and the relevant medical specialties should be included in participatory processes at all stages, including prior to an actual policy decision, to secure broad support for scaling-up. nnTo facilitate negotiations and planning, information on the expected impact of the model on users, providers (e.g. workload, training requirements) and costs should be assessed and disseminated. nnThe model must be adapted to local contexts and service-delivery settings.

Health system or organizational-level considerations for implementation of the model nnIntroduction of the model should involve pre-service training institutions and professional bodies, so that training curricula for ANC can be updated as quickly and smoothly as possible. nnLong-term planning is needed for resource generation and budget allocation to strengthen and sustain high-quality ANC services. nnIn-service training and supervisory models will need to be developed according to health-care providers’ professional requirements, considering the content, duration and procedures for the selection of providers for training. These models can also be explicitly designed to address staff turnover, particularly in low-resource settings. nnStandardized tools will need to be developed for supervision, ensuring that supervisors are able to support and enable health-care providers to deliver integrated, comprehensive ANC services. nnA strategy for task shifting may need to be developed to optimize the use of human resources. nnTools or “job aids” for ANC implementation (e.g. ANC cards) will need to be simplified and updated with all key information in accordance with the model. nnStrategies will need to be devised to improve supply chain management according to local requirements, such as developing protocols for the procedures of obtaining and maintaining the stock of supplies, encouraging providers to collect and monitor data on the stock levels and strengthening the provider- level coordination and follow-up of medicines and health-care supplies required for implementation of the ANC model.

User-level considerations for implementation of the model nnCommunity-sensitizing activities should be undertaken to disseminate information about the importance of each component of ANC, and pregnant women’s right to attend ANC for their health and the health of their unborn baby. This information should provide details about the timing and content of the recommended ANC contacts, and about the expected user fees. nnIt may be possible to reduce waiting times by reorganizing ANC services and/or client flow.

For specific implementation considerations related to the individual recommendations, see Annex 4.

The Box 7 , priority research questionsare grouped • What is the prevalence of GDM and diabetes mellitus in pregnancy, according to the new criteria, in various populations and ethnic groups? What are the best screening strategies for GDM and what are the prevalence thresholds at which these are cost-effective? • What is the effect of daily fetal movement counting, such as the use of “count-to-ten” kick charts, in the third trimester of pregnancy on perinatal outcomes in LMICs? • What are the effects and accuracy of SFH measurement to detect abnormal fetal growth and other risk factors for perinatal morbidity (e.g. multiple pregnancy, polyhydramnios) in settings without routine ultrasound? • Can a single routine Doppler ultrasound examination of fetal blood vessels for all pregnant women in the third trimester accurately detect or predict pregnancy complications, particularly IUGR and pre-eclampsia, and lead to improved pregnancy outcomes?

C. Preventive measures

• What are the effects of prophylactic antibiotics to prevent RUTI in pregnancy, compared to monitoring with use of antibiotics only when indicated, on maternal infections, perinatal morbidity and antimicrobial drug resistance? • What is the prevalence of Rh alloimmunization and associated poor outcomes among pregnant women in LMIC settings? Can cost-effective strategies be developed to manage this condition in LMICS and improve equity?

D. Interventions for common physiological symptoms

• What is the prevalence of common physiological symptoms among pregnant women in low-resource settings, and can the offer of treatment of these symptoms reduce health inequality, improve ANC coverage and improve women’s pregnancy experiences? • What is the etiology of leg cramps in pregnancy, and does treatment with magnesium and/or calcium relieve symptoms?

E. Health systems interventions to improve utilization and quality of ANC

• What should be included in women-held case notes, and how can discrepancies across different records be reduced to improve quality of care? • What is the pathway of influence of midwife-led continuity of care (MLCC)? Is it specifically the continuity, the provider–client relationship or the midwifery philosophy that leads to better health outcomes and maternal satisfaction? Can this effect be replicated with other cadres of health-care providers, e.g. auxiliary nurse midwives, nurses, family doctors, etc.? How can ANC in LMICs be structured to incorporate the active ingredients of MLCC, particularly in settings where the number of midwives is very limited? • What are the effects, feasibility and resource implications of MLCC in LMICs? Which models are most feasible (i.e. caseload or team models)? Can a continuity model for group ANC be developed for settings where other MLCC models are not feasible? • Can a group ANC model be developed for LMICs, to provide guidance on the optimal group size, frequency and content of group ANC contacts? • Is group ANC acceptable (data should include the views of women who decline to participate), feasible and cost-effective in LMIC settings? • Are mixed models (group and individual ANC) feasible and acceptable, and are there benefits to mixed models? • What are the effects of group ANC on maternal and perinatal health outcomes, coverage outcomes (ANC contacts and facility-based births), and women’s and providers’ experiences? • Should women with complicated pregnancies also be offered group ANC, for the communication and social support aspects, in addition to receiving specialist care? • How acceptable and feasible are mixed-gender community mobilization groups? What are the optimal methods for community-based interventions to improve communication and support for pregnant women and adolescent girls; to improve integration of community-based mobilization efforts with health systems; and to ensure continuity of care with home visits? What are the mechanisms of effect of these interventions? • Can the 2016 WHO ANC model with a minimum of eight contacts impact the quality of ANC in LMICs, and what is the effect on health, values, acceptability, resources, feasibility and equity parameters?
