OBJECTIVE: This article reviews the evidence for the effectiveness of non-clinical interventions to reduce maternal mortality in low-income settings and identifies the gaps in the evidence base. METHODS: A systematic search was conducted to identify reviews and evaluations of non-clinical interventions to reduce maternal mortality in lower-income countries with high maternal mortality published between 1997 and 2008. Studies were reviewed to identify the topic focus, study design, and outcomes measured. RESULTS: There were 109 intervention evaluations and 30 reviews identified. Studies had been conducted in less than half of the countries and were generally poor quality. More studies focused on tertiary prevention (i.e., preventing death) rather than secondary prevention (i.e., preventing complications). More interventions sought to address quality of care than delays in seeking or accessing care. CONCLUSIONS: While evidence partly reflects difficulties in evaluating complex public health interventions, more robust study designs are possible to evaluate interventions to reduce maternal mortality. In addition, better standardized outcome measures are needed. This overview identifies topic areas neglected by intervention research.
