BackgroundReview of maternal deaths relies on comprehensive documentation of medical records that can reveal sequence of events that led to death. Maternal Death and Surveillance (MDSR) system recommends the use of narrative summaries during maternal death reviews to discuss the case and categorize medical causes of death, identify gaps in care and recommend action plans to prevent deaths. Suggested action plans are recommended to be Specific, Measurable, Attainable, Relevant and Time bound (SMART). To identify gaps in documenting information and planning recommendations, comprehensiveness of written narrative summaries and adequacy of action plans according the MDSR guideline were assessed. MethodsA total of 76 facility maternal deaths that occurred in two regions in Southern Tanzania in 2018 were included for analysis. We assessed the comprehensiveness of narrative summaries and action plans using a prepared checklist from MDSR guideline of 2015. Presence or absence of items in four domains each with several attributes was recorded on the checklist. The domains were socio-demographic characteristics, antenatal care, referral information and events that occurred after admission. Less than 75% completeness of attributes in all domains was considered poor while >94% was good/comprehensive. Action plans were assessed by application of SMART criteria and according to place of planned implementation (community, facility or higher level of health system). Results Two-thirds of summaries (66%) scored poor, and none were scored as good/comprehensive. Summaries missed key information such as demographic characteristics, information of events that occurred in community (16%), time between diagnosis of complication and commencing treatment (65%), investigation results (47%), summary of case evolution (51%) and referral information (47%). A total of 285 action plans were analysed. Most action plans 242(85%) were allocated to health facilities for implementation and they were mostly 42(42%) on service delivery. Only 42% (32/76) of the action plans were deemed to be SMART.ConclusionsAbstraction of information to prepare narrative summaries used in MDSR system is inadequately done. Action plans and recommendations in MDSR system are mostly for facility sub standards of care and are not specific on the issues to be addressed.
