PREVALENCE AND FACTORS ASSOCIATED WITH RUPTURE OF GRAVID UTERUS AND FETO-MATERNAL OUTCOME: A ONE-YEAR RETROSPECTIVE COHORT STUDY

Abstract

Background: Uterine rupture remains a significant public health problem contributing to 13% of maternal mortality and 74%-92% for perinatal mortality in developing countries. This study assesses the prevalence and factors associated with rupture of gravid uterus and feto-maternal outcome in Ethiopian mothers with uterine rupture.

Methods: A retrospective cohort study was conducted to identify risk factors associated with rupture of gravid uterus and feto-maternal outcomes. The data source included clinical records of patients seen at Dilla University Referral Hospital over a one-year period. The data was collected using a structured data collection form developed for the purposes of the study. The study involved a total 2,498 women with a gravid uterus, gestational age of ?28 weeks and registered in the labor and delivery registration books in the Obstetrics and Gynecology Department. Bivariate and multivariate regression analyses were carried out at 95% Confidence Interval to identify factors independently associated with uterine rupture.

Results: Out of 2,498 reviewed deliveries, 46 cases developed uterine rupture making an overall hospital prevalence of 1.8 % or one in 53 deliveries. Malpresentation (80%), contracted pelvis (47.8%), vertex malposition (10.8%), and previous uterine scar (2.1%) were the causes of uterus ruptures. In multivariate analysis, clients’ residence, parity, birth weight, Antenatal Care follow-up and duration of labor were statistically significantly associated with uterine rupture. Maternal and fetal case fatality rates were 8.7% and 97.8%, respectively.

Conclusion: Uterine rupture remains an important problem in the study area. Patients with identified risk factor(s) should stay close to the hospital in late pregnancy. Besides, strengthening antenatal care follow-up and referral linkage should be considered.
