An Assessment of DHS Maternal Mortality Indicators

Abstract

This study presents an assessment of the quality of data relating to maternal mortality collected in 14 Demographic and Health Surveys (DHS) for 13 countries that included a complete sibling history. Four aspects of data quality are considered: completeness of the data for reported events, evidence of omission in the reporting of events, plausibility of the pattern of sibling deaths, and sampling errors of the maternal mortality estimates. Although the data relating to reported events are complete for most variables, comparisons of sibling-history-based estimates of adult mortality for both males and females with other independent estimates suggest that sibling estimates are more likely to be underestimates than overestimates. The downward bias is probably greater for female mortality than for male mortality. The sampling errors associated with maternal mortality ratios are substantially larger than those associated with other frequently used DHS indicators. This lack of precision precludes the use of these data for trend analysis and has led to the recommendation that this DHS module not be used more than once every ten years in the same country.

Estimating pregnancy-related mortality from census data: experience from Latin America

“…Although data sources such as the Demographic and Health Surveys have improved our knowledge of process indicators related to maternal mortality, such as institutional deliveries or skilled attendant at delivery, the estimates of maternal mortality have been disappointing. 29,30 Census data may also provide a unique opportunity to study regional or socioeconomic differentials in maternal mortality, an advantage not offered by estimates from sibling-based methods such as those used by the Demographic and Health Surveys. It is clear, however, that additional validation of this method (for example, in demographic surveillance sites) could lead to increased accuracy of …”

Maternal Mortality and Maternity Care from 1990 to 2005: Uneven but Important Gains

“…It has been shown that the sisterhood method underestimates the actual level of maternal mortality. 4,5 Large sample sizes are needed for estimating maternal mortality in this way and the confidence intervals of the estimates are relatively wide. However, the data allow comparisons across countries because of the standard instruments and design.…”

Maternal death and near miss measurement: a case for implementation in developing countries in the sustainable development agenda, a review article

“…In Nigeria, proportional maternal mortality (PM) was 31.2% and 15.6% in 1990 and 2013 respectively (32). This depicts that death from pregnancy and child birth may be the most important killer of women in the reproductive age group in Nigeria.…”
