[Dystocia risk score: a decision making tool to combat maternal mortality].

As a way to prevent maternal mortality and stillbirth, the dystocia risk score includes three components: a left column provides a list of eight characteristics to check for in the woman; an upper horizontal section provides a checklist of possible outcomes of the pregnancy itself: and a rectangular grid indicates the prognosis in three zones: a large red (dangerous), a medium-sized grey (doubtful) and a small blue (hopeful). The DRS is positive if there is at least one cross in the dangerous zone and/or two crosses in the doubtful zone (it indicates that the woman should be referred to a center specialized in obstetric emergency care); elsewhere, the DRS is negative. The validation test gives good results (sensitivity=83.61%, specificity=90.05%, positive predictive value=72.34%, and negative predictive value=94.04%). Its large-scale use would accelerate the identification of pregnant women with a high risk of dystocia. Their timely referral to specialized emergency obstetrics centers would increase the efficacy of care and reduce the levels of maternal mortality and stillbirth.
