Introduction Increases in facility deliveries in sub-Saharan Africa have not yielded expected declines in maternal mortality, raising concerns about the quality of care provided in facilities. The readiness of facilities at different health system levels to provide both emergency obstetric and newborn care (EmONC) as well as referral is unknown. We describe this combined readiness by facility level and region in Senegal.
Methods For this cross-sectional study, we used data from nine Demographic and Health Surveys between 1992 and 2017 in Senegal to describe trends in location of births over time. We used data from the 2017 Service Provision Assessment to describe EmONC and emergency referral readiness across facility levels in the public system, where 94% of facility births occur. A national global positioning system facility census was used to map access from lower-level facilities to the nearest facility performing caesareans.
Results Births in facilities increased from 47% in 1992 to 80% in 2016, driven by births in lower-level health posts, where half of facility births now occur. Caesarean rates in rural areas more than doubled but only to 3.7%, indicating minor improvements in EmONC access. Only 9% of health posts had full readiness for basic EmONC, and 62% had adequate referral readiness (vehicle on-site or telephone and vehicle access elsewhere). Although public facilities accounted for three-quarters of all births in 2016, only 16% of such births occurred in facilities able to provide adequate combined readiness for EmONC and referral.
Conclusions Our findings imply that many lower-level public facilities—the most common place of birth in Senegal—are unable to treat or refer women with obstetric complications, especially in rural areas. In light of rising lower-level facility births in Senegal and elsewhere, improvements in EmONC and referral readiness are urgently needed to accelerate reductions in maternal and perinatal mortality.

What is already known?
Despite increases in facility deliveries in sub-Saharan Africa, maternal and perinatal mortality remains unacceptably high, partly due to limited readiness to treat obstetric complications in facilities.
What are the new findings?
In Senegal, although three-quarters of births occurred in public facilities in 2016, only 16% of these took place in facilities able to provide comprehensive emergency obstetric and newborn care (EmONC), or basic EmONC and referral to a comprehensive EmONC facility.
37% of rural health posts were located more than 1-hour drive from the nearest facility performing caesareans.
What do the new findings imply?
Lower-level public health posts—the most common place of birth in Senegal—are often unable to provide high-quality care during childbirth, or timely emergency referral to a higher-level facility.
Improvements in referral and EmONC readiness, particularly in rural areas, are urgently needed in lower-level facilities in Senegal and other countries where many births occur in lower-level facilities.
Measuring facilities’ capacity to provide EmoNC or refer to such facilities within a reasonable travel time is a powerful means of identifying women and areas that are left behind.
In recent decades, maternal mortality has decreased in sub-Saharan Africa; however, progress was insufficient to meet Millennium Development Goal 5 in most countries.1 The global maternal health community must now focus on countries left behind and accelerate progress to achieve Sustainable Development Goals (SDGs) target 3.1 for maternal health. Sub-Saharan Africa has the highest burden of maternal and perinatal mortality.2–4 Limited improvements in maternal and perinatal outcomes despite rising facility deliveries raises questions regarding the quality of care provided in health facilities.5–7
Skilled attendance at birth and access to emergency obstetric and newborn care (EmONC) are essential for preventing maternal and perinatal deaths.8 9 There is agreement that a strategy of universal facility deliveries with a skilled birth attendant (SBA) is optimal for reducing mortality.10 Accordingly, the percentage of births in facilities and with SBA are commonly used to track coverage of maternal care services.11 However, there is great variability in the quality of care offered across facilities and birth attendants. In the 2016 Lancet Maternal Health series, Campbell et al proposed a framework outlining safe care pathways for women and their babies, arguing most deliveries should occur in facilities providing at least basic EmONC (BEmONC), as well as either comprehensive EmONC (CEmONC) or facilitated referral to a CEmONC facility.9 The recent Lancet Quality Care Commission argued that redesigning services to shift delivery care from lower-level facilities to health centres or hospitals could yield significant gains in quality of maternal and neonatal care, without unduly compromising geographical access to care.12
Previous studies have highlighted low readiness to provide childbirth care in health facilities in sub-Saharan Africa, due to low provider skill and suboptimal equipment and supplies.13–21 Evidence on referral systems for transferring patients with complications between facilities in low-income countries is limited22 but indicates that these are often not functional or non-existent, with lack of communication and transport means, and poor road infrastructure.23–25 Overall, there is little evidence on readiness for EmONC jointly with referral capacity, despite referral being necessary for safe childbirth care in non-CEmONC facilities, and on readiness by facility level or geographical area.
This paper addresses these gaps in the evidence base by mapping Campbell’s framework against the health systems framework used by governments to organise maternal and newborn health services and allocate resources. In an attempt to bring childbirth services closer to women and increase facility deliveries, several governments in sub-Saharan Africa have encouraged births in lower-level dispensaries or health posts; however, this strategy risks offering substandard care far away from any referral hospital.12 Among these countries, Senegal has achieved 80% facility births, but a large proportion of these are attended by unskilled attendants.9 It also has recent women and facility surveys available. We therefore selected Senegal as a case study to investigate the potential quality of care implications of these national policies, which need to be aligned with international EmONC frameworks. We propose an approach to assess readiness for EmONC and emergency referral within countries by examining facilities at different levels of the health system (hospitals, health centres, health posts and health huts), as well as across urban/rural areas and geographical regions, to identify gaps in care provision and facilitate the prioritisation of resource allocation. This study provides evidence that will inform policy-makers’ strategies in Senegal and other low-income and middle-income countries to accelerate reductions in maternal mortality. In addition, it aims to stimulate global debate on indicators used to assess maternal health system readiness and use, and their role in shaping strategies to reduce maternal mortality.
This paper addresses two central research questions: first, where do women deliver in Senegal and how has this changed over time? Second, what is the readiness for treating obstetric complications and referring women with complications, according to facility level and region? We used Campbell et al’s conceptual framework of pathways to adequate childbirth care9 to systematically assess service readiness in hospitals, health centres, health posts and health huts. Within this framework, deliveries should occur either in a CEmONC facility, or a BEmONC facility with facilitated emergency referral to a CEmONC facility, in case the woman develops complications—we consider facilities in these categories to provide minimum safe conditions for childbirth. We assessed facilities’ readiness for EmONC and emergency referral jointly among public facilities included in the Service Provision Assessment (SPA), and calculated driving time from facilities without caesarean capacity to those with caesarean capacity among all public facilities in Senegal. We did not calculate driving times from BEmONC to CEmONC facilities as proposed by Ebener et al26 because it was not possible to ascertain EmONC readiness for all health facilities in Senegal, and most facilities did not fall into either BEmONC or CEmONC categories.
Senegal is a West African country (population of 16 million in 2017) with large rural areas and long distances to health facilities, limiting access to childbirth care.27 Large regional disparities exist in healthcare infrastructure, utilisation and outcomes, with more urbanised coastal regions in the West—including the capital Dakar—performing better than predominantly rural regions in the East and South (box 1).28 29
Sociodemographic characteristics of regions in Senegal
Urban centre: The capital Dakar is the most urbanised region of Senegal, with 97% urban population. It contains approximately one-quarter of the country’s population, and has the highest population density with more than 6000 inhabitants per km2 as well as the lowest total fertility rate at 3.0 children per woman. Only 5% of women report distance to health facilities as a barrier to accessing healthcare.
Rural regions with large urban centres: Four regions (Thiès, Kaolack, Saint-Louis and Ziguinchor) have large urban centres but remain predominantly rural, with 35%–46% urban population. Population density is relatively high (over 170 inhabitants per km2 in the urban districts, but substantially lower in rural districts). Fertility is below five children per woman in these regions, with the exception of Kaolack (5.2). These regions account for 31% of Senegal’s population.
Rural regions: The remaining regions have low urbanisation rates (15%–26%) and high fertility (5.1–6.4 children per woman). Four regions in the Centre and North (Diourbel, Fatick, Kaffrine and Louga) have long distances to facilities, with 18%–39% of women reporting distance as a barrier to accessing healthcare. This issue is more pronounced in five isolated rural regions in the East and South (Matam, Tambacounda, Kédougou, Kolda and Sédhiou) with very low population density and 36%–50% of women reporting distance as a barrier to access. Together, these nine rural regions account for 46% of Senegal’s population.
Senegal’s public health system is pyramid shaped, with health posts referring patients to their district health centre, and health centres referring patients to the regional hospital.30 Some health posts further coordinate a small network of rural health huts. Regional and national hospitals are intended to provide all CEmONC signal functions, including caesarean sections, while few health centres have surgical capacity. Health posts are lower-level facilities with a small number of inpatient beds, traditionally staffed by nurses and matrones (birth assistants with 3–6 months of training, considered unskilled birth attendants),29 although increasingly also midwives (considered SBA). Health huts tend to be a single room with a bed staffed part time by community health agents such as matrones, funded by village health committees rather than the Ministry of Health and Social Action (MoHSA).
Maternal mortality in Senegal remained high at 315 per 100 000 live births in 2017, down from 540 in 1990.31 Improving maternal and newborn health is a political priority in Senegal, listed as the first objective of the 2009–18 National Health Development Plan.32 User fee exemptions for childbirth and caesareans were selectively introduced in 2005,33 and expanded to include all public facilities, although some patient fees remain. Among sub-Saharan countries with Demographic and Health Survey (DHS) data, Senegal has the highest percentage of women delivering in facilities who report no skilled attendant (19% in 2014),9 34 and the deficit of midwives was estimated at 50% of the need in 2013.32 35 Low availability of anticonvulsants for hypertensive disorders, manual vacuum extractors and provider CEmONC training have been highlighted as gaps in EmONC readiness.36
We used data from nine DHS conducted in Senegal between 1992–1993 and 2017. The DHS are nationally representative, standardised surveys of women of reproductive age, collecting information on births and childbirth care.37 The four annual continuous DHS between 2012–2013 and 2016 had smaller sample sizes38: we grouped the 2012–2013 and 2014 DHS, and the 2015 and 2016 DHS, to increase statistical power and generate regionally representative estimates.
To assess facility EmONC and referral readiness in hospitals, health centres, health posts and health huts, we used data on infrastructure, staffing and equipment for childbirth collected in the most recent SPA, a nationally representative survey of facilities of all sectors (public, private not-for-profit, private for-profit and private religious).39 Our study focuses on public facilities where 94% of facility births occur29; our sample includes 476 public facilities reporting to provide delivery care in the 2017 SPA.40
Lastly, we used a geo-referenced MoHSA census of public facilities in Senegal, excluding health huts.41 Facility location was classified using a WorldPop population density raster.42 Facilities were considered urban if they were located in a 100 m2 grid square with population density above 10, to maximise agreement with the SPA classification. We identified all public facilities (hospitals and health centres) performing caesareans in November 2018, using information from prior facility-based studies,43 44 the SPA, and key informants, including the MoHSA and Senegalese coauthors. Discrepancies between sources occurred for six facilities, which we resolved by contacting the relevant district medical officers.
Detailed indicator definitions are included in online supplementary appendix 1.
For each DHS, we estimated the percentage (and 95% CI) of births by place and birth attendant among all live births in the 2 years prior to the survey, based on women’s self-report. We also calculated the population caesarean section rate as a proportion of live births in the 2 years before the survey, as an indicator of CEmONC access. Our estimates are based on 31 108 live births to 29 938 women across the seven time points. We further tested differences in place of birth between the earliest (1992–1993) and most recent (2017) surveys using X2 tests, and used United Nations Population Department data on population size and birth rate to estimate the average absolute number of births per year in the 2-year recall period of each time point.45 46
Using 2017 SPA data, we described facility readiness to provide routine childbirth care, EmONC and emergency referrals by facility level. Facilities were considered to provide BEmONC-1 if they reported ever providing and having available equipment for six signal functions—selected key interventions used to treat direct obstetric complications47 (antibiotics, oxytocin, anticonvulsants, manual removal of placenta, removal of retained products and neonatal resuscitation; see online supplementary appendix 1). We excluded assisted vaginal delivery (by forceps or vacuum) from BEmONC signal functions due to data quality concerns. Facilities were considered to provide CEmONC-1 if they provided BEmONC-1 and both CEmONC signal functions (caesarean sections and blood transfusion). We calculated the median number of each provider cadre employed and total SBAs (doctors, midwives and nurses) by facility level and urban/rural location within the public sector. Facilities were considered to have adequate referral readiness if they had a vehicle available for referrals, or had a telephone available and reported access to a vehicle elsewhere. We estimated the percentage of public sector births occurring in facilities with different levels of EmONC or referral readiness by multiplying the percentage of facilities in each readiness category in each facility level by the corresponding percentage of women reporting to deliver in each health facility level in the 2017 DHS. We performed this calculation for all births in Senegal and by region.
All DHS and SPA analyses took into account survey weights, as well as clustering and stratification where appropriate.
We created maps showing the locations of public facilities with and without caesarean capacity using R.48 Driving time to the nearest caesarean facility was estimated by calculating the driving time from facilities without caesarean capacity to each facility with caesarean capacity, and selecting the one with the shortest driving time. We used the OpenStreetMap-Based Routing Service (OSRM) package in R,49 50 which allows for the computation of travel time between points based on assumptions relating to vehicle and road characteristics, such as average speed.51 Eighteen facilities had long estimated driving times (>3 hours) most often due to lack of proximity to marked roads on OSRM; we replaced these with driving times reported by district medical officers in relevant districts (see online supplementary appendix 2, table S1). Lastly, we described urban–rural and regional variations in childbirth care utilisation and facility readiness.
Patient and public involvement
Patients or the public were not involved in the design, conduct, reporting or dissemination of our research.
National trends in childbirth care utilisation over time
The percentage of births in facilities in Senegal rose steadily from 47% of live births in 1992 to 80% in 2016 (see online supplementary table S2, figure 1). This 1.7-fold increase corresponds to a threefold rise in the absolute number of facility births from 156 000 to 465 000 per year in the same period (online supplementary figure S2). Most of the rise in both urban and rural areas occurred in public health posts, which accounted for over 70% of the increase in facility births in this period (p<0.001, online supplementary table S2). Births in public health centres increased by six percentage points (p=0.001). There was no evidence of a national rise in births in public hospitals or non-public facilities; in fact, births in public hospitals declined by 10 percentage points among urban women (p=0.001). In 2016, public health posts accounted for 42% of all births (half of facility births), compared with 19% in public health centres and 11% in public hospitals. Under 5% of births occurred in each health huts and non-public facilities.
Trends in facility-based births were unequal across the country. Overall, women living in rural areas were more likely than urban women to deliver in lower-level facilities (53% in health posts and huts compared with 34%, respectively; figure 1). There was substantial regional variation: while 96% of women in Dakar gave birth in facilities in 2016, this figure was only 52%–56% in the rural South-East (figure 2B; see online supplementary table S3 for detailed regional breakdowns). The proportion of births taking place at different facility levels also varied throughout the country, with higher hospital delivery rates in the three most urbanised regions (Dakar, Saint-Louis and Ziguinchor) and higher health hut deliveries in the Centre and South.
In 1992, the proportion of births attended by an SBA was identical to the proportion of facility births (47%). However, by 2016, only 71% of all births were reported to be assisted by an SBA, compared with 80% births in facilities (see online supplementary figure S1). Important fluctuations in self-reported birth attendant were observed between surveys. In 2016, 14% of women delivering in public facilities reported being assisted by a non-SBA (primarily matrones), including 14% in public health posts and 85% in public health huts (see online supplementary figure S3). Overall, 90% of births among urban women—but only 60% among rural women—were attended by an SBA in 2016 (see online supplementary figure S1).
The national caesarean section rate more than doubled from 2.4% to 6.0% over 25 years (p<0.001, online supplementary table S2), representing a fourfold absolute increase from 8000 to 35 000 caesarean births per year. However, this increase was primarily driven by a rise in urban areas; although they are still lagging behind, the caesarean rate also increased from 1.7% to 3.7% in rural areas (see online supplementary table S2). In 2016, 14% of births were by caesarean in Dakar, compared with at most 5% in all other regions (figure 2C).
Facility readiness for EmONC and staffing at different levels of the public health system
Around 85% of hospitals and health centres reported providing childbirth care in 2017, compared with 93% of health posts and less than half of health huts (see online supplementary table S4).
Combined readiness for all BEmONC-1 functions was only 8%–10% in health posts, 26%–28% in health centres and 40% in hospitals (table 1, figure 3A). There was little difference in BEmONC-1 readiness between urban and rural health centres and posts; it was strikingly low both in the capital (24%) and other regions (0 in two rural Southern regions; online supplementary table S3). Overall, only 17% of public sector births in Senegal occur in facilities able to provide all BEmONC-1 functions. Readiness for anticonvulsants, manual removal of placenta and removal of retained products was particularly low in health centres and posts; only two-thirds of hospitals had readiness to provide antibiotics. Only 2% of public health centres and one third of hospitals had full CEmONC-1 readiness, although 15 of the 17 hospitals performed both CEmONC functions (caesarean section and blood transfusion, regardless of BEmONC capacity; table 1).
Readiness to provide routine childbirth care was also poor in lower-level public facilities (table 1). Infection prevention, routine partograph use and water supply were relatively available, but 24hour childbirth care and continuous electricity were especially low in rural health posts (4% and 26%, respectively). Data on EmONC readiness were not collected from health huts, since they are not expected to have BEmONC capacity; however, continuous electricity (3%), infection prevention measures (42%), and water supply (43%) were suboptimal.
Of 1259 public facilities in the national census, we identified 40 with functional caesarean capacity in November 2018, with unequal regional distribution (12 in the Dakar region, compared with only one in each of four regions in the Centre and South). Facilities performing caesareans were concentrated in urban areas with higher pregnancy density, and vast rural areas lacked caesarean coverage, particularly in Northern, Eastern and South-Eastern regions (figure 4A).
Staffing varied substantially according to public facility level (see online supplementary table S5). No SBAs were employed in health huts. Although all facilities above health huts employed at least one SBA, rural health posts had very low staff numbers, with a median of one nurse and one midwife, and 30% did not employ a midwife. In contrast, urban health posts employed a median of two nurses and two midwives. Hospitals and health centres had higher median staff numbers and more variability, with a median of at least two doctors and four midwives in rural and urban facilities.
Readiness for emergency referrals
Adequate referral readiness—defined as either on-site vehicle access, or telephone with remote vehicle access—was 100% in hospitals and 95% in health centres, but only 62% in health posts and 15% in health huts (figure 3B). Overall, 73% of public sector births occurred in facilities with adequate referral readiness. Striking regional variation was observed, from 12% of facilities in rural Kolda to 91% in Ziguinchor (see online supplementary table S3), and 12%–13% of health posts had no access to a referral vehicle (table 2). Only 3% of health huts reported a vehicle on-site, and two-thirds lacked any formal vehicle access.
Among public health centres and posts without caesarean capacity, the nearest facility performing caesareans was located at a median distance of 32 km, or 41 min’ driving time (table 2). Median driving times were much higher for rural health centres and posts (47–48 min) than urban facilities (6–10 min). More than one-third of rural health posts and one-quarter of rural health centres were located at least 1-hour driving time from the nearest caesarean facility. Important geographical differences in driving times were observed (figure 4B); the median ranged from 5 min in Dakar to 1hour 40min in rural South-Eastern Kédougou (see online supplementary table S3).
Combined EmONC and emergency referral readiness
Overall, 40% of public hospitals, 29% of public health centres and 6% of public health posts were able to provide minimum safe childbirth conditions (either full CEmONC-1, or BEmONC-1 with adequate referral readiness; figure 3C). This figure was higher in urban (14%) than rural areas (3%) for all facilities; around 16% of all public sector births in Senegal occurred in such facilities. Dakar was the best performing region (37% of births in facilities meeting minimum safe conditions, with 18% of births nationally) compared with less than 10% in seven rural regions, collectively accounting for 46% of all births in Senegal (see online supplementary table S3).
Using DHS and SPA data as well as a national census of health facilities in Senegal, we found that lower-level health posts and huts—where the majority of facility births occur—lack the emergency obstetric care and referral readiness to provide high-quality, timely care to women and babies during childbirth. Over the 25 years between 1992 and 2016, facility births rose from 47% to 80%, representing a threefold increase in absolute numbers—from 156 000 to 465 000 annually. This is a substantial achievement for the MoHSA and reproductive health partners. However, most of this increase occurred through women’s utilisation of lower-level health posts and huts, accounting for 46% of all births or 266 000 births in 2016. Readiness for emergency obstetric care and referral declined steeply from health centres to health posts, and health huts, and only 16% of public facility births occurred in facilities able to provide safe childbirth conditions. Moreover, an estimated 14% of facility deliveries—or 64 000 deliveries in 2016—took place with an unskilled matrone, the highest percentage in sub-Saharan Africa.9 Improvements in caesarean section rates were concentrated in urban areas, indicating that rising facility births did not greatly improve access to emergency obstetric and newborn care in rural areas. In line with previous studies finding substantially lower effective than crude coverage of childbirth care,18 52–54 these findings raise important concerns about the quality of care provided to women in Senegalese facilities, and elsewhere in sub-Saharan Africa.
Women in rural areas are particularly affected by low facility readiness. In urban areas, 50% of women give birth in larger hospitals and health centres, and more facilities are able to provide safe childbirth conditions (14% compared with 3% in rural areas). The caesarean rate of 10% suggests that women are usually able to reach a higher-level facility when needed: although the referral system is reportedly ineffective—many referrals take place with taxis or private vehicles—in urban areas some women can bypass the formal referral system with their own means thanks to proximity to higher-level facilities (median driving time of 6–10 min, with important differences between regions). In contrast, more than half of rural women give birth in health posts and huts, and one-quarter at home. One-third of rural health posts employ only one nurse, with no midwife. Although EmONC and referral readiness were similarly low in urban and rural health centres and posts, consequences for maternal and perinatal health are much more severe in rural areas, where distances to the nearest CEmONC facility are substantially longer and alternative transport means less available. The situation is even more concerning in community-owned rural health huts, where 4% or 25 000 births occur annually: health huts do not employ skilled attendants, EmONC is not available, and two-thirds do not have adequate referral readiness. The caesarean rate below 4% among rural women—and at most 5% in all regions outside Dakar—highlights an unmet need for life-saving EmONC55 despite the substantial increase in facility births, and suggests that the referral system is not optimal in rural areas. There are no accepted guidelines for maximum duration of obstetric referrals in high-income or low-income countries; however, obstetricians’ associations in the UK and USA have targets of 30 min decision-to-delivery intervals for caesarean sections for foetal compromise.56 57 This is an unattainable target for the vast majority of women delivering in rural facilities, with median driving times of over 45 min to the nearest caesarean facility.
Reliable subnational estimates are not available; however, women from isolated rural areas likely contribute disproportionately to maternal deaths and stillbirths. Improvements in women’s EmONC access in urban areas likely contributed to the 40% reduction in maternal mortality in Senegal since 199031: to accelerate progress and meet SDG targets, Senegal must now address gaps in emergency obstetric care and referral in rural areas. Our study found important gaps in treatment of hypertensive diseases and haemorrhage in particular, which account for 14% and 27% of maternal deaths, respectively.58 Other studies in sub-Saharan Africa also found that BEmONC readiness is low in lower-level facilities as well as higher-level facilities with caesarean or blood transfusion capacity; in particular, assisted vaginal deliveries are often unavailable.16 59 60 Poor BEmONC readiness is problematic because early detection and management of complications is essential for preventing a need for higher-level care and severe maternal outcomes. For example, uterotonic drugs and manual removal of retained placenta can stop postpartum haemorrhage early and prevent the need for urgent blood transfusion or hysterectomy. BEmONC readiness is therefore particularly valuable in the context of long travel times to referral facilities. A recent study in Ghana found that facility birth without EmONC capacity does not necessarily reduce maternal or perinatal mortality.7
Facility staffing and readiness estimates in health posts and huts likely represent the best-case scenarios. Although facilities may have the equipment needed and have provided a signal function previously, it does not ensure such care is provided in a timely manner to all women who need it. The number of SBAs employed in health posts—particularly rural ones—is insufficient to ensure skilled attendance to all women during childbirth. Although 99% of health posts employ a nurse in-charge (considered an SBA), competing clinical responsibilities for outpatient consultations mean no SBAs are dedicated solely to delivery care. In 2013, the deficit of midwives in Senegal was estimated at around 50% of total need for workforce time.32 35 The MoHSA travelling midwives initiative61 and recruitment efforts under the National Family Planning Action Plans62 have led to a substantial rise from 48% health posts employing midwives in 2014 to 75% in 2017. However, it is likely to have a limited impact on quality of childbirth care in health posts with limited EmONC readiness. In such circumstances, the capacity for timely and effective transfer to hospital is critical to the reduction of maternal and perinatal mortality, particularly in rural areas.
Emergency referral readiness was lacking in many health posts and huts. In practice, providers may use personal mobile phones to contact referral facilities; however, such informal pathways are problematic for rapidly requesting ambulances and warning the referral facility of incoming referrals. Vehicle availability may also be overestimated in health posts, where they are also used for outreach and administrative duties, and may not always be available or have petrol when needed. Total referral time for facilities without a vehicle includes time to request an ambulance (usually from the referral facility), for the ambulance to arrive and drive to the referral facility. Therefore, total time for the woman to reach the referral facility is likely substantially longer than the estimated median driving time of 41 min. Similar gaps in referral systems have also been noted in Tanzania.63
Our study has some limitations. We focused on childbirth care, known to be crucial for the survival of women and babies, although antenatal and postnatal care are also essential. Similarly, we reported access to facilities performing caesareans as a proxy for advanced EmONC, because surgical capacity is more easily ascertainable, although other EmONC interventions (including blood transfusions) are equally critical. We did not assess readiness in non-public facilities, where only 5% of births occur in Senegal.
Unlike in other countries, the Senegal SPA did not collect the number of deliveries in each facility. We were thus unable to calculate results weighted by delivery volume. However, we used the percentage of women giving birth in each facility level and readiness level as proxies. Facilities appeared to misreport assisted vaginal delivery (over 90% of health huts reported having performed forceps or vacuum deliveries); we therefore excluded it from our BEmONC estimates. Our definition of BEmONC signal functions based on facilities having ever provided them probably overestimates readiness; however, restricting to performance in the last 3 months would introduce bias since lower-level facilities with fewer patients might not have needed to provide signal functions within this period. Our categories of facility-level mask important differences in facility environment between, for example, health centres in Dakar and isolated rural districts.
Women may have misreported their birth attendant, probably overestimating their qualification,64 as highlighted by fluctuations in SBA between 2010 and 2016, probably too large to reflect true changes over this short period. The combined percentage of SBA cadres and matrones shows a slow and steady increase over time, suggesting matrones are mistaken for SBAs by some women, including the 14% of women delivering in health huts who reported SBA. Observations would provide a better understanding of who assisted women during childbirth than the DHS or SPA, however, women’s reports in the DHS align with staff numbers and responsibilities in facilities in the SPA, suggesting that unskilled attendants assist a non-negligible percentage of facility births in Senegal. Women are less likely to misreport facility level.65
Lastly, OpenStreetMap algorithms are based on assumptions of vehicle speed which may underestimate driving time in the rainy season or peak traffic hours, and overestimate driving time where no marked roads exist. Driving times are likely much greater for health huts than health posts. Use of district medical officer reports for the 18 facilities with long driving time estimates is imprecise, although it is unlikely to have biased median driving times since both modelled and reported estimates were above the upper quartile. Our estimates represent driving times to facilities performing caesareans, and may underestimate driving time to facilities with other advanced EmONC services.
Implications for policy and programmes
We echo the call from the 2016 Lancet series that ‘it is unethical to encourage women to give birth in places with low facility capability, no referral mechanism, with unskilled providers, or where content of care is not evidence based.’9 Women should be urgently encouraged to deliver in health centres and hospitals,5 with the aim of shifting the majority of deliveries away from health posts not meeting requirements for safe delivery and referral, and actively discouraged from delivering in health huts. Commensurate improvements in capacity (including staff, maternity beds and equipment) must be made in hospitals and health centres to accommodate this substantial number of additional deliveries. Health hut readiness is not meaningfully different from home environments, therefore, births in health huts should not be included in Senegal’s facility births estimates.
The biggest challenge facing Senegal—and many countries in Sub-Saharan Africa—is how to provide high-quality childbirth care to women in rural areas with low population density, high fertility rates and long distances to facilities. Determining where the balance should lie between bringing delivery care closer to women in lower-level facilities with lower capacity (such as health posts), and centralising material and human resources in health centres and hospitals while improving referrals from lower-level facilities, needs to occur in a considered manner and on a region-by-region basis.66 The 2009–2018 National Health Development Plan aimed for surgery to be available in all health centres32; however, selectively upgrading health centres based on driving time to nearest facility with caesarean capacity is likely a better use of resources. Overcoming distance to facilities in rural areas is one of the greatest challenges in sub-Saharan Africa. Although the Lancet Quality Care Commission recommends centralising deliveries in hospitals,12 this is currently unattainable in the most rural regions in Senegal, and a gradual shift away from health posts to health centres is more realistic. The challenge of childbirth care coverage is unlikely to be addressed by the health sector alone, as demonstrated by China’s achievements in lowering maternal mortality in rural provinces through additional focus on roads, women’s education and poverty reduction.67
Multisectoral interventions are needed to improve emergency referral readiness as the first priority in rural areas, where most births occur in lower-level facilities unable to provide CEmONC. All health posts should be equipped with telephones, and formalised communication protocols for referring and referral facilities should be developed and implemented.22 Subnational budgets should prioritise paving roads from health posts to main roads, and additional interventions should be trialled, including strategically placed shared ambulances and maternity waiting homes adjacent to health centres and hospitals.22 68 69 Strengthening antenatal care would enable referral to higher-level facilities for women with preidentifiable conditions (including twin pregnancy and pre-eclampsia).70–72 The extent of informal use of health services between Senegal and neighbouring Gambia is unknown; however, providers in Senegal are unable to refer to facilities in the Gambia, even if those are nearer: reciprocal formal arrangements between these countries for obstetric emergencies should be considered.
Moreover, EmONC readiness should be improved through equipment availability and regular training and supervision at all health system levels, particularly health posts in the short term and health centres as deliveries shift to this facility level. Additional investment in human resources are needed, particularly in rural facilities. Improving quality of care is a huge challenge requiring substantial financial and programme investments from the Senegalese government and reproductive health partners. Improving access to safe abortion in addition to existing contraception efforts,73 74 and increasing female education, would help prevent higher-risk births and abortion-related mortality.
As highlighted previously, the percentage of births in facilities alone is limited in its ability to track progress in effective coverage of childbirth care.75 Facility readiness surveys should be conducted routinely alongside population-based surveys, and every effort should be made to report the percentage of facilities providing minimum safe childbirth conditions and of births in such facilities—in addition to the commonly reported facility births and EmONC facilities per population11—to improve quality of care for women and newborns globally.
Over the last quarter century, the Senegalese health system has accommodated a threefold increase in annual number of facility deliveries, predominantly by caring for women in public lower-level health posts. However, our findings show that the majority of women giving birth in health facilities are not meaningfully captured in a health system capable of providing high-quality care and timely referral for obstetric emergencies. Women in rural areas are particularly underserved as a result of long distances to CEmONC facilities, and likely contribute disproportionately to persistent high maternal and perinatal mortality despite increases in facility deliveries. This case study illustrates that promoting births in lower-level facilities might not produce care of adequate quality or timeliness in other sub-Saharan countries adopting similar national strategies. The global health community needs to expand indicators beyond facility deliveries and SBA to capture the quality of care women receive at birth, including the percentage of facilities providing safe childbirth conditions and the percentage of births in such facilities, as proposed in this article. The Senegalese government’s commitment to reducing maternal mortality is noteworthy—to accelerate reductions in maternal and perinatal mortality, there is now an urgent need to improve referral readiness in rural facilities and EmONC readiness across all facilities, as well as to put policies in place which encourage women to deliver in health centres and hospitals.
We thank the women and health facility staff who participated in the DHS and SPA surveys, and the DHS Programme for making these data available. We are also grateful to the Ministry of Health and Social Action for helping us compile the list of facilities performing caesareans, to MEASURE Evaluation for sharing data from the Urban Reproductive Health Initiative evaluation, and to the District Medical Officers who verified caesarean capacity and driving times to referral facilities in their districts. We are thankful to Siri Suh for the inspiration for the title of this article (see reference number 74).
