[Maternal mortality among socially vulnerable women in France 2016-2018].

Social vulnerability is a known factor in perinatal medical risk, both for the foetus and the mother. As part of the French confidential enquiry into maternal deaths, the introduction in 2015 of specific items relating to social status has made it possible to recreate this composite variable. Over the period 2016-2018, one woman in three who died was in a situation of social vulnerability. Of these 79 deaths, 32 (41%) were related to direct obstetric causes, 26 (33%) to indirect obstetric causes, 12 (15%) to suicides and 8 (10%) of unknown cause. Care was considered sub-optimal in 73% of cases, compared with 64% in the group of maternal deaths with no identified social vulnerability. 43 deaths were judged to be probably (n=12) or possibly (n=31) avoidable, 25 were not avoidable, and 11 were not sufficiently documented for this assessment; i.e. a proportion of 63% of probable or possible avoidability, a higher proportion compared with the 56% of avoidability among women with no identified social vulnerability. In 1/3 of maternal deaths, a lack of interaction between the woman and the healthcare system was involved in the chain of events leading to death, i.e. 2 times more than in the case of socially non-vulnerable women. Improving the interaction of women in socially vulnerable situations with the hospital system and the institutional and voluntary networks providing care, support and assistance is a priority. A specific, responsive medical and social organisation could contribute to this.
