Objective — to carry out a retrospective analysis of maternal mortality n preeclampsia and eclampsia in the Tula Region in 2001—2015. Material and methods. The incidence of preeclampsia and eclampsia in the Tula Region in January 1, 2007 to December 12, 2014 was retrospectively analyzed. The dynamics and structure of causes of maternal deaths in the Tula Region in the past 15 years were explored. The copies of primary medical records, postmortem examination protocols, forensic medical examination reports, statistical reports, expert maternal death information report forms, and case study protocols were investigated. Results. Morbidity associated with these pregnancy complications was shown to be lower than that in the Russian Federation; however, there was a moderate increase in this indicator over the analyzed period. Preeclampsia and eclampsia (25.7%) ranked first among the causes of maternal deaths in the Tula Region. There were the most common outpatient and inpatient medical care errors: underestimation of early- onset symptoms (24—32 weeks), unjustified hospital discharge, ineffective therapy after delivery, and undercounting the choice of the level of a hospital. Death was determined preventable in one half of the cases (5/9). Conclusion. The study shows that a reduction in maternal deaths due to preeclampsia/eclampsia requires that clinical protocols for medical care ensuring adequate antenatal care, early diagnosis, adequate treatment, and timely delivery should be strictly adhered to. There is a need for research to develop predictors for preeclampsia in both the high risk group and the general population to determine criteria for early and timely diagnosis, markers for progression of the process.
