[Maternal deaths related to social vulnerabilities. Results from the French confidential enquiry into maternal deaths, 2010-2012].

The theme of deprivation is new for the ENCMM. In view of the perceived increase in the number of maternal deaths that may be related to a deprivation situation, we sought to understand the main dimensions that could contribute to maternal death in this context, in order to propose a definition. The selection of cases made a posteriori is mainly based on a qualitative judgment. Between 2010 and 2012, among the deaths evaluated by the CNEMM, one or more elements related to social vulnerability were identified in 8.6% of the cases (18 deaths). The direct criteria used were the concepts of "deprivation" or "social difficulties", difficulties of housing, language barriers and isolation. The absence of prenatal care was retained as an indirect marker. We excluded cases where psychiatric pathology and/or addiction were predominant. Of the 18 cases identified with deprivation factors, death was considered "unavoidable" in 2 cases (11%), "certainly avoidable" or "possibly avoidable" in 13 cases (72%). In 3 cases (17%), avoidability could not be determined. Avoidability was related to the content and adequacy of care in 11 cases out of 13 (85%) and the patient's interaction with the health care system in 10 of 18 cases (56%). The analysis of maternal deaths among women in precarious situations points out that the link between socio-economic deprivation and poor maternal health outcomes potentially includes a specific risk of maternal death.
