Emergency obstetric care (EmOC) signal functions are a shortlist of key clinical interventions capable of averting deaths from the five main direct causes of maternal mortality; they have been used since 1997 as a part of an EmOC monitoring framework to track the availability of EmOC services in low- and middle-income settings. Their widespread use and proposed adaptation to include other types of care, such as care for newborns, is testimony to their legacy as part of the measurement architecture within reproductive health. Yet, much has changed in the landscape of maternal and newborn health (MNH) since the initial introduction of EmOC signal functions. As part of a project to revise the EmOC monitoring framework, we carried out a meta-narrative inspired review to reflect on how signal functions have been developed and conceptualised over the past two decades, and how different narratives, which have emerged alongside the evolving MNH landscape, have played a role in the conceptualisation of the signal function measurement. We identified three overarching narrative traditions: 1) clinical 2) health systems and 3) human rights, that dominated the discourse and critique around the use of signal functions. Through an iterative synthesis process including 19 final articles selected for the review, we explored patterns of conciliation and areas of contradiction between the three narrative traditions. We summarised five meta-themes around the use of signal functions: i) framing the boundaries; ii) moving beyond clinical capability; iii) capturing the woods versus the trees; iv) grouping signal functions and v) measurement challenges. We intend for this review to contribute to a better understanding of the discourses around signal functions, and to provide insight for the future roles of this monitoring approach for emergency obstetric and newborn care.

BACKGROUND: Abortion-related complications contribute to preventable maternal mortality, accounting for 9.8% of maternal deaths globally, and 15.6% in sub-Saharan Africa. High-quality postabortion care (PAC) can mitigate the negative health outcomes associated with unsafe abortion. While the expanded Global Gag Rule policy did not prohibit the provision of PAC, other research has suggested that over-implementation of the policy has resulted in impacts on these services. The purpose of this study was to assess health facilities\' capacity to provide PAC services in Uganda and PAC and safe abortion care (SAC) in Ethiopia during the time in which the policy was in effect.
METHODS: We collected abortion care data between 2018 and 2020 from public health facilities in Ethiopia (N = 282) and Uganda (N = 223). We adapted a signal functions approach to create composite indicators of health facilities\' capacity to provide basic and comprehensive PAC and SAC and present descriptive statistics documenting the state of service provision both before and after the GGR went into effect. We also investigate trends in caseloads over the time-period.
RESULTS: In both countries, service coverage was high and improved over time, but facilities\' capacity to provide basic PAC services was low in Uganda (17.8% in 2019) and Ethiopia (15.0% in 2020). The number of PAC cases increased by 15.5% over time in Uganda and decreased by 7% in Ethiopia. Basic SAC capacity increased substantially in Ethiopia from 66.7 to 82.8% overall, due in part to an increase in the provision of medication abortion, and the number of safe abortions increased in Ethiopia by 9.7%.
CONCLUSIONS: The findings from this analysis suggest that public health systems in both Ethiopia and Uganda were able to maintain essential PAC/SAC services during the GGR period. In Ethiopia, there were improvements in the availability of safe abortion services and an overall improvement in the safety of abortion during this time-period. Despite loss of partnerships and potential disruptions in referral chains, lower-level facilities were able to expand their capacity to provide PAC services. However, PAC caseloads increased in Uganda which could indicate that, as hypothesized, abortion became more stigmatized, less accessible and less safe.

BACKGROUND: The provision of quality obstetric care in health facilities is central to reducing maternal mortality, but simply increasing childbirth in facilities not enough, with evidence that many facilities in sub-Saharan Africa do not fulfil even basic requirements for safe childbirth care. There is ongoing debate on whether to recommend a policy of birth in hospitals, where staffing and capacity may be better, over lower level facilities, which are closer to women\'s homes and more accessible. Little is known about the quality of childbirth care in Liberia, where facility births have increased in recent decades, but maternal mortality remains among the highest in the world. We will analyse quality in terms of readiness for emergency care and referral, staffing, and volume of births.
METHODS: We assessed the readiness of the Liberian health system to provide safe care during childbirth use using three data sources: Demographic and Health Surveys (DHS), Service Availability and Readiness Assessments (SARA), and the Health Management Information System (HMIS). We estimated trends in the percentage of births by location and population caesarean-section coverage from 3 DHS surveys (2007, 2013 and 2019-20). We examined readiness for safe childbirth care among all Liberian health facilities by analysing reported emergency obstetric and neonatal care signal functions (EmONC) and staffing from SARA 2018, and linking with volume of births reported in HMIS 2019.
RESULTS: The percentage of births in facilities increased from 37 to 80% between 2004 and 2017, while the caesarean section rate increased from 3.3 to 5.0%. 18% of facilities could carry out basic EmONC signal functions, and 8% could provide blood transfusion and caesarean section. Overall, 63% of facility births were in places without full basic emergency readiness. 60% of facilities could not make emergency referrals, and 54% had fewer than one birth every two days.
CONCLUSIONS: The increase in proportions of facility births over time occurred because women gave birth in lower-level facilities. However, most facilities are very low volume, and cannot provide safe EmONC, even at the basic level. This presents the health system with a serious challenge for assuring safe, good-quality childbirth services.

OBJECTIVE: To evaluate the capability of high-volume comprehensive emergency obstetric care (CEmOC) health facilities on the provision of comprehensive postabortion care (PAC) in Sub-Saharan Africa and to determine the frequency of women with severe abortion-related complications in high capability facilities.
METHODS: A cross-sectional analysis conducted across 11 countries in Sub-Saharan Africa, using facility-level information from the World Health Organization (WHO) Multi-Country Survey on Abortion-related morbidity (MCS-A) between 2017 and 2018. PAC signal functions were adapted to assess facilities\' capability to deliver comprehensive PAC through infrastructure, standard comprehensive capability, and extended comprehensive capability to provide PAC. The percentage of facilities with each signal function and distribution of facilities by number of signal functions were calculated for the three capability categories. Distribution of severe abortion complications by facility capability score was assessed.
RESULTS: Of 210 high-volume CEmOC facilities included, 47.9% (n = 100) had capability to provide all facility infrastructure signal functions, 54.4% (n = 105) for standard comprehensive PAC, reducing to 17.7% (n = 34) for extended comprehensive PAC capability. Overall, there were gaps in extended capabilities including availability of a functioning ICU (available in 37.3% of facilities) and providers 24/7 (65.5% of facilities reported an obstetrician available 24/7 dropping to 41.3% for anesthesiologists). Facilities\' PAC capability varied across regions. Overall, 34.6% (n = 614) of women with severe abortion-related complications were treated in facilities with the maximum capability score for extended comprehensive PAC.
CONCLUSIONS: Although high levels of capability to provide abortion-related care for most signal functions were evident, significant gaps that impact on the management of severe abortion-related complications remain, particularly related to extended facility capabilities including specialized human resources and ICU.

BACKGROUND: sub-Saharan African Low and Lower-Middle Income Countries (sSA LLMICs) have the highest burden of maternal and perinatal morbidity and mortality in the world. Timely and appropriate maternal referral to a suitable health facility is an indicator of effective health systems. In this systematic review we aimed to identify which referral practices are delivered according to accepted standards for pregnant women and newborns in sSA LLMICs by competent healthcare providers in line with the needs of pregnant women.
METHODS: Six electronic databases were systematically searched for primary data studies (2009-2018) in English reporting on maternal referral practices and their effectiveness. We conducted a content analysis guided by a framework for assessing the quality of maternal referral. Quality referral was defined as: timely identification of signal functions, established guidelines or standards, adequate documentation, staff accompaniment and prompt care by competent healthcare providers in the receiving facility.
RESULTS: Seventeen articles were included in the study. Most studies were quantitative (n = 11). Two studies reported that women were dissatisfied due to delays in referral processes that affected their health. Most articles (10) reported that women were not accompanied to higher levels of care, delays in referral processes, transport challenges and poor referral documentation. Some healthcare providers administered essential drugs such as misoprostol prior to referral.
CONCLUSIONS: Efforts to improve maternal health in LLMICs should aim to enhance maternity care providers\' ability to identify conditions that demand referral. Low cost transport is needed to mitigate barriers of referral. To ensure quality maternal referral, district level health managers should be trained and equipped with the skills needed to monitor and evaluate referral documentation, including quality and efficiency of maternal referrals.
BACKGROUND: Systematic review registration: PROSPERO registration CRD42018114261 .

BACKGROUND: Good quality maternal and newborn care at primary health facilities is essential, but in settings with high maternal and newborn mortality the evidence for the protective effect of facility delivery is inconsistent. We surveyed samples of health facilities in three settings with high maternal mortality to assess their readiness to provide routine maternal and newborn care, and proportions of women using facilities that were ready to offer good quality care. Surveys were conducted in 2012 and 2015 to assess changes over time.
METHODS: Surveys were conducted in Ethiopia, the Indian state of Uttar Pradesh and Gombe State in North-Eastern Nigeria. At each facility the staffing, infrastructure and commodities were quantified. These formed components of four \"signal functions\" that described aspects of routine maternal and newborn care. A facility was considered ready to perform a signal function if all the required components were present. Readiness to perform all four signal functions classed a facility as ready to provide good quality routine care. From facility registers we counted deliveries and calculated the proportions of women delivering in facilities ready to offer good quality routine care.
RESULTS: In Ethiopia the proportion of deliveries in facilities classed as ready to offer good quality routine care rose from 40% (95% confidence interval (CI) 26-57) in 2012 to 43% (95% CI 31-56) in 2015. In Uttar Pradesh these estimates were 4% (95% CI 1-24) in 2012 and 39% (95% CI 25-55) in 2015, while in Nigeria they were 25% (95% CI 6-66) in 2012 and zero in 2015. Improved facility readiness in Ethiopia and Uttar Pradesh arose from increased supplies of commodities, while in Nigeria facility readiness fell due to depleted commodity supplies and fewer Skilled Birth Attendants.
CONCLUSIONS: This study quantified the readiness of health facilities to offer good quality routine maternal and newborn care, and may help explain inconsistent outcomes of facility care in some settings. Signal function methodology can provide a rapid and inexpensive measure of such facility readiness. Incorporating data on facility deliveries and repeating the analyses highlighted adjustments that could have greatest impact upon routine maternal and newborn care.

BACKGROUND: An estimated 65,000 abortions occurred in Zimbabwe in 2016, and 40 % resulted in complications that required treatment. Quality post-abortion care (PAC) services are essential to treat abortion complications and prevent future unintended pregnancies, and there have been recent national efforts to improve PAC provision. This study evaluates two components of quality of care: structural quality, using PAC signal functions, a monitoring framework of key life-saving interventions that treat abortion complications; and process quality, which examines the standards of care provided to PAC patients.
METHODS: We utilized a 2016 national census of health facilities in Zimbabwe with PAC capacity (n = 227) and a prospective, facility-based 28-day survey of women seeking PAC in a nationally representative sample of those facilities (n = 1002 PAC patients at 127 facilities). PAC signal functions, which are the critical services in the management of abortion complications, were used to classify facilities as having the capability to provide basic or comprehensive care. All facilities were expected to provide basic care, and referral-level facilities were designed to provide comprehensive care. We also assessed population coverage of PAC services based on the WHO recommendation for obstetric services of 5 facilities per 500,000 residents.
RESULTS: We found critical gaps in the availability of PAC services; only 21% of facilities had basic PAC capability and 10% of referral facilities had comprehensive capability. For process quality, only one-fourth (25%) of PAC patients were treated with the appropriate medical procedure. The health system had only 41% of the basic PAC facilities recommended for the needs of Zimbabwe\'s population, and 55% of the recommended comprehensive PAC facilities.
CONCLUSIONS: This is the first national assessment of the Zimbabwean health system\'s coverage and quality of PAC services. These findings highlight the large gaps in the availability and distribution of facilities with basic and comprehensive PAC capability. These structural gaps are a contributing barrier to the provision of evidence-based care. This study shows the need for increased focus and investment in expanding the provision of and improving the quality of these essential, life-saving PAC services.

OBJECTIVE: The purpose of this health system\'s study is to assess the availability of Emergency Obstetric Care (EmOC) services in birthing centres in Taplejung District of eastern Nepal.
METHODS: A cross-sectional survey was conducted in 2018 in all 16 public health facilities providing delivery services in the district. Data collection comprised: (1) quantitative data collected from health workers; (2) observation of key items; and (3) record data extracted from the health facility register. Descriptive statistics were used to calculate readiness scores using unweighted averages.
RESULTS: Although key health personnel were available, EmOC services at the health facilities assessed were below the minimum coverage level recommended by the World Health Organisation. Only the district hospital provided the nine signal functions of Comprehensive EmOC. The other fifteen had only partially functioning Basic EmOC facilities, as they did not provide all of the seven signal functions. The essential equipment for performing certain EmOC functions was either missing or not functional in these health facilities.
UNASSIGNED: The Ministry of Health and Population and the federal government need to ensure that the full range of signal functions are available for safe deliveries in partially functioning EmOC health facilities by addressing the issues related to training, equipment, medicine, commodities and policy.

Maternal morbidity and mortality is most prevalent in resource-poor settings such as sub-Saharan Africa and southern Asia. In sub-Saharan Africa, Ghana is one of the countries still facing particular challenges in reducing its maternal morbidity and mortality. Access to emergency obstetric care (EmOC) interventions has been identified as a means of improving maternal health outcomes. Assessing the range of interventions provided in health facilities is, therefore, important in determining capacity to treat obstetric emergencies. The aim of this study was to examine the availability of emergency obstetric care interventions in the Upper East Region of Ghana.
A cross-sectional survey of 120 health facilities was undertaken. Status of emergency obstetric care was assessed through an interviewer administered questionnaire to directors/in-charge officers of maternity care units in selected facilities. Data were analysed using descriptive statistics.
Eighty per cent of health facilities did not meet the criteria for provision of emergency obstetric care. Comparatively, private health facilities generally provided EmOC interventions less frequently than public health facilities. Other challenges identified include inadequate skill mix of maternity health personnel, poor referral processes, a lack of reliable communication systems and poor emergency transport systems.
Multiple factors combine to limit women\'s access to a range of essential maternal health services. The availability of EmOC interventions was found to be low across the region; however, EmOC facilities could be increased by nearly one-third through modest investments in some existing facilities. Also, the key challenges identified in this study can be improved by enhancing pre-existing health system structures such as Community-based Health Planning and Services (CHPS), training more midwifery personnel, strengthening in-service training and implementation of referral audits as part of health service monitoring. Gaps in availability of EmOC interventions, skilled personnel and referral processes must be tackled in order to improve obstetric outcomes.

BACKGROUND: Zambia\'s maternal mortality ratio was estimated at 398/100,000 live births in 2014. Successful aversion of deaths is dependent on availability and usability of signal functions for emergency obstetric and neonatal care. Evidence of availability, usability and quality of signal functions in urban settings in Zambia is minimal as previous research has evaluated their distribution in rural settings. This survey evaluated the availability and usability of signal functions in private and public health facilities in Lusaka District of Zambia.
METHODS: A descriptive cross sectional study was conducted between November 2014 and February 2015 at 35 public and private health facilities. The Service Availability and Readiness Assessment tool was adapted and administered to overall in-charges, hospital administrators or maternity ward supervisors at health facilities providing maternal and newborn health services. The survey quantified infrastructure, human resources, equipment, essential drugs and supplies and used the UN process indicators to determine availability, accessibility and quality of signal functions. Data on deliveries and complications were collected from registers for periods between June 2013 and May 2014.
RESULTS: Of the 35 (25.7% private and 74.2% public) health facilities assessed, only 22 (62.8%) were staffed 24 h a day, 7 days a week and had provided obstetric care 3 months prior to the survey. Pre-eclampsia/ eclampsia and obstructed labor accounted for most direct complications while postpartum hemorrhage was the leading cause of maternal deaths. Overall, 3 (8.6%) and 5 (14.3%) of the health facilities had provided Basic and Comprehensive EmONC services, respectively. All facilities obtained blood products from the only blood bank at a government referral hospital.
CONCLUSIONS: The UN process indicators can be adequately used to monitor progress towards maternal mortality reduction. Lusaka district had an unmet need for BEmONC as health facilities fell below the minimum UN standard. Public health facilities with capacity to perform signal functions should be upgraded to Basic EmONC status. Efforts must focus on enhancing human resource capacity in EmONC and improving infrastructure and supply chain. Obstetric health needs and international trends must drive policy change.
