The United Nations Process Indicators for emergency obstetric care: Reflections based on a decade of experience.

OBJECTIVE: The paper reviews the experience with the EmOC process indicators, and evaluates whether the indicators serve the purposes for which they were originally created - to gather and interpret relatively accessible data to design and implement EmOC service programs. METHOD: We review experience with each of the 6 process indicators individually, and monitoring change over time, at the level of the facility and at the level of a region or country. We identify problems encountered in the field with data collection and interpretation. RESULT: While they have strengths and weaknesses, the process indicators in general serve the purposes for which they were developed. The data are easily collected, but some data problems were identified. We recommend several relatively minor modifications to improve data collection, interpretation and utility. CONCLUSIONS: The EmOC process indicators have been used successfully in a wide variety of settings. They describe vital elements of the health system and how well that system is functioning for women at risk of dying from major obstetric complications.

Measuring progress towards the MDG for maternal health: including a measure of the health system's capacity to treat obstetric complications.

OBJECTIVE: This paper argues for an additional indicator for measuring progress of the Millennium Development Goal for maternal health-the availability of emergency obstetric care. METHODS: MDG monitoring will be based on two indicators: the maternal mortality ratio and the proportion of births attended by skilled personnel. Strengths and weaknesses of a third indicator are discussed RESULTS: The availability of EmOC measures the capacity of the health system to respond to direct obstetric complications. Benefits to using this additional indicator are its usefulness in determining an adequate distribution of services and showing management at all levels what life-saving interventions are not being provided, and stimulate thought as to why. It can reflect programmatic changes over a relatively short period of time and data requirements are not onerous. CONCLUSION: A measure of strength of the health system is important since many interventions depend on the health system for their implementation.

Global patterns in availability of emergency obstetric care.

OBJECTIVE: This paper examines the availability of basic and comprehensive emergency obstetric care (EmOC), interventions used to treat direct obstetric complications. Determining what interventions are provided in health facilities is the first priority in analyzing a country's capabilities to treat obstetric emergencies. There are eight key interventions, six constitute basic EmOC and all eight comprehensive EmOC. METHODS AND RESULTS: Based on data from 24 needs assessments, the following global patterns emerge: comprehensive EmOC facilities are usually available to meet the recommended minimum number for the size of the population, basic EmOC facilities are consistently not available in sufficient numbers, both in countries with high and moderate levels of maternal mortality, and the majority of facilities offering maternity services provide only some interventions indicating an unrealized potential. CONCLUSION: Upgrading maternities, health centers and hospitals to at least basic EmOC status would be a major contributing step towards maternal mortality reduction in resource-poor countries.

The availability of life-saving obstetric services in developing countries: an in-depth look at the signal functions for emergency obstetric care.

OBJECTIVE: This paper examines the frequency with which a set of life-saving interventions or signal functions was performed to treat major obstetric complications. METHODS AND RESULTS: The basic signal functions include parenteral antibiotics, anticonvulsants and oxytocics, and the procedures of manual removal of the placenta, removal of retained uterine products, and assisted vaginal delivery. Comprehensive functions include the six basic functions, cesarean delivery, and blood transfusions. Data from 1906 health facilities in 13 countries indicate that the most likely functions to be reported are oxytocics and antibiotics. The basic function least likely to be reported is assisted vaginal delivery. Many of the facilities surveyed did not have the infrastructure to perform operations or provide blood transfusions. CONCLUSIONS: These data can help governments allocate their budgets appropriately, help policy makers and planners identify systemic bottlenecks and prioritize solutions. Monitoring the performance of the functions informs us of the capacity of the health system to provide key interventions when obstetric emergencies occur.

The evidence for emergency obstetric care.

PURPOSE: We searched for evidence for the effectiveness of emergency obstetric care (EmOC) interventions in reducing maternal mortality primarily in developing countries. METHODS: We reviewed population-based studies with maternal mortality as the outcome variable and ranked them according to the system for ranking the quality of evidence and strength of recommendations developed by the US Preventive Services Task Force. A systematic search of published literature was conducted for this review, including searches of Medline, PubMed, Cochrane Database of Systematic Reviews, the Cochrane Pregnancy and Childbirth Database and the Cochrane Controlled Trials Register. RESULTS: The strength of the evidence is high in several studies with a design that places them in the second and third tier in the quality of evidence ranking system. No studies were found that are experimental in design that would give them a top ranking, due to the measurement challenges associated with maternal mortality, although many of the specific individual clinical interventions that comprise EmOC have been evaluated through experimental design. There is strong evidence based on studies, using quasi-experimental, observational and ecological designs, to support the contention that EmOC must be a critical component of any program to reduce maternal mortality.

Program note: applying the UN process indicators for emergency obstetric care to the United States.

The United Nations Process Indicators for emergency obstetric care (EmOC) have been used extensively in countries with high maternal mortality ratios (MMR) to assess the availability, utilization and quality of EmOC services. To compare the situation in high MMR countries to that of a low MMR country, data from the United States were used to determine EmOC service availability, utilization and quality. As was expected, the United States was found to have an adequate amount of good-quality EmOC services that are used by the majority of women with life-threatening obstetric complications.
