Moving from indicators of facility coverage and use toward capability to reduce maternal mortality

A primary indicator that tracked progress toward reducing maternal mortality prior to the Sustainable Development Goals (SDGs) was the percentage of women delivering with a skilled birth attendant. The assumption was that skilled attendants would ensure women receive quality, evidence-based services. It is true that more women are delivering with skilled attendants now than in 1990, and that more deliveries are taking place in health care facilities; it is also true that ratios of maternal mortality have decreased. Yet, the relationship between increased facility deliveries and reduced mortality within countries is mixed. Why is that? One explanation could be that a quality gap remains.

We need to move away from relying on one-dimensional indicators of coverage and use toward indicators that more adequately capture the complexity of facility capability and quality.

To understand this better, we need to move away from relying on one-dimensional indicators of coverage and use toward indicators that more adequately capture the complexity of facility capability and quality. This will help the maternal health community better track changes at health facilities and support national and subnational entities to identify and target needed interventions. Together with Oona Campbell of the London School of Hygiene and Tropical Medicine (LSHTM) and colleagues, our team analyzed data from 50 countries in an article in The Lancet Maternal Health Series to characterize the availability of critical infrastructure and services where women deliver. Here I present some of those findings that are also included in my lecture that is part of a free online Maternal Health Series course developed by LSHTM.

Key indicators highlighting the variation of capability across countries can be broken down into five broad categories: basic infrastructure, routine delivery services, emergency obstetric services, timeliness of care, and time in a facility. The new Maternal Health Series lecture largely highlights data from four countries – China, Ghana, Mozambique and Rwanda. Countries have various levels of capability; these more complex indicators are helpful in characterizing that variation across countries, and could also be used to understand differences within countries by region, facility type and sector. The four countries included in this blog exemplify important differences in terms of level of health facility capability to provide delivery services.

Basic infrastructure
Presence of basic infrastructure is a precondition of good quality services.
Presence of basic infrastructure is a precondition of good quality services. Electricity is needed for lighting, proper temperature storage of drugs and blood, operating medical equipment like oxygen and anesthesia machines, and sterilizing equipment. Likewise, improved water, sanitation and hygiene practices, as well as infection prevention practices are critical determinants for maternal and newborn survival. Infections account for 14% of early newborn deaths and nearly half of late newborn deaths, and puerperal sepsis (postpartum infections) caused almost one in 10 maternal deaths in 2013. Many of these deaths are attributable to inadequate hygiene. For these reasons, the SDGs target improvements in electricity and water infrastructure in health care facilities; yet, little is known about the current status.

Results of a systematic review show that 66% of hospitals in sub-Saharan African countries lack electricity; another study finds that 38% of facilities lack improved water, 19% lack improved sanitation, and 35% lack water and soap for handwashing. In our article, we look at the presence of three elements of basic infrastructure relative to where women are delivering – water, electricity, and the 24/7 availability of services. Figure 1 indicates that many deliveries take place in facilities that are open at all times, but lack either water or reliable electricity.

The vast majority of deliveries in Ghana in 2010 occur in facilities with all three elements in place (shown in green). By contrast, in Rwanda in 2007, just one-quarter of deliveries occur in facilities with all three elements. Mozambique is between the two, with about three-quarters of deliveries occurring in facilities with all three infrastructure items.

Note that this chart, and others below, presents the distribution of deliveries according to the capability of facilities where the delivery occurred. This presentation offers important context around the exposure of women and newborns to poor (or strong) facility capability. However, from a planning perspective, countries would also want to understand the proportion – and geographic location – of facilities with important capability gaps to target improvements.

Routine delivery services
Despite global efforts toward the skilled birth attendant strategy, little attention has been paid to routine intrapartum care (delivery) in facilities.
Despite global efforts toward the skilled birth attendant strategy, little attention has been paid to routine intrapartum care (delivery) in facilities. However, Gabrysch and colleagues proposed signal functions for routine care and basic infrastructure in 2012. Signal functions are key medical interventions or services required for the provision of quality, evidence-based care. These proposed signal functions for routine delivery include infection prevention, the use of a partograph to monitor labor, and routine administration of a uterotonic as part of active management of the third stage of labor (AMTSL). The graph in Figure 2 shows the proportion of deliveries occurring in facilities of various levels of routine delivery capability.

In Ghana in 2010, just over 13% of deliveries occur in facilities missing at least one routine signal function. In Rwanda in 2007, that proportion is three-quarters of deliveries, and in Mozambique in 2012 about one-third. These three seemingly simple services should be available to every woman who delivers. Yet, many women deliver in facilities where these services are missing, increasing their chance of dying from sepsis, hemorrhage, and obstructed labor.

Emergency obstetric services
Signal functions describe a facility’s capability to deliver a package of life-saving interventions that target the common causes of maternal death.
We can also look at signal functions to describe facility capability to deliver a package of life-saving interventions that target the common causes of maternal death. Commonly referred to as emergency obstetric care or EmOC, this indicator has been monitored for almost two decades.

A facility provides comprehensive EmOC if it has recently provided nine signal functions. Basic EmOC indicates a basic level of complication management that should be available at most mid- to low-level facilities; we refer to the tiered levels of basic EmOC as fully basic (7 signal functions), approaching basic (5 or 6 signal functions), limited functioning (2 to 4 signal functions), and substandard (0-1 signal functions) in Figure 3.

Note that many countries have essentially abandoned the practice of assisted vaginal delivery – i.e., delivery with forceps or vacuum extraction – thus, basic EmOC services are sometimes measured by excluding that life-saving intervention. The fully basic category includes basic services without assisted vaginal delivery.

Figure 3: Distribution of facility deliveries by facility EmOC status

Figure 3: Distribution of facility deliveries by facility EmOC status

Figure 3 shows that facilities’ capability to provide EmOC varies, and is often poor. In Rwanda in 2007, 36% of deliveries occur in facilities that provide zero or one basic signal function, as indicated in red. In Ghana in 2010, this proportion is 3%. Women in China in 2011 are considerably more likely to deliver in facilities providing full EmOC services than those in sub-Saharan Africa.

Timeliness of care
A woman’s access to timely life-saving care must be independent of her ability to pay.
High-quality care requires that all components of routine and emergency care be provided consistently, respectfully, and in a timely fashion, to all women who need them. We know that individual women’s care can be very poor, but information on individual-level quality is hard to come by. In a 2004 study, Gohou and colleagues looked at the time lapse between admission and surgery, in hours, among six women admitted with uterine rupture in two hospitals in Côte d’Ivoire. Only one woman received an operation within 1 hour. The other 5 women waited upwards of 4 hours, with the delay at times dependent upon the woman’s ability to purchase a complete surgical kit. Women unable to raise the required funds in time are at greater risk of dying. This illustrates a dire inequity that is widespread, though wholly unacceptable. A woman’s access to timely life-saving care must be independent of her ability to pay.

Time in facility
Women and newborns discharged early are not appropriately monitored during a time that they remain highly vulnerable to life-threatening complications.
WHO recommends monitoring women and newborns over the first 24 hours. Yet, lengths-of-stay vary across countries and can be quite short. A Ministry of Health report on emergency obstetric services in Ethiopia in 2008 shows most women stay at a facility fewer than 12 hours after delivery. (My colleagues and I describe the report’s methodology and the policy and programmatic changes resulting from the report in this paper.) In a similar Ministry assessment in 2016, the median stay after a normal delivery remained 12 hours; among private facilities it was just 6 hours. Whereas, in Kenya in 2009, Campbell and her co-authors show that almost 75% of women stayed for at least 24 hours. Women and newborns discharged early are not appropriately monitored during a time that they remain highly vulnerable to life-threatening complications. If a complication develops – whether in the mom or the baby – they must return to the facility for treatment which can be very difficult and costly. Many are not able or choose not to make the trip.

In conclusion, there are multiple country data sources with which to characterize features of facilities including: their delivery volume, whether they have adequate infrastructure, their capability to provide routine and emergency care, and how long women stay after delivery. We also know facilities’ capability to provide timely care to individual women is key, but unfortunately such data are not routinely tracked.

The indicators described above are better suited for capturing the complexity of facility capability. Using these indicators – together with indicators of coverage and use – will better position the global community to track changes and will support health planners in-country to identify and target interventions to further reduce maternal mortality.
