Abstract

Abstract: Objectives: To assess the diagnostic performance of the EPICES score for identifying social deprivation during pregnancy in a population of women in the immediate postpartum period. Study design: This cross-sectional survey took place between 5th June and 5th August 2017, among women who had just given birth in either of the maternity units in Clermont-Ferrand, France. Methods: A self-administered questionnaire was completed by women. The questionnaire came in two parts: the EPICES index and the criteria for social deprivation defined by French law. These criteria were chosen to define the reference standard. The women were classified into two groups, living in precarious circumstances or not, according to the criteria defined by the French law (reference standard). To determine the most relevant threshold of the EPICES score, the precision associated with the threshold (the fraction of those predicted positive who are true positives: positive predictive value) was balanced with its sensitivity. EPICES scores above the threshold were classified as deprived, those below as non-deprived. Results: Of the 947 women who gave birth during the study period, 700 (73.9%) completed the self-administered questionnaire. The best trade-off between precision and sensitivity was obtained with a threshold of 22. For this threshold value, the positive predictive value was 42.3% and the sensitivity 70.3%. Conclusions: The EPICES score with a threshold validated in the population of pregnant women is a useful, rapid, and easy-to-use tool that makes it possible to identify maternal deprivation at an individual level.
