Maternal morbidity and mortality have long been among the world’s most challenging health issues. Uterine rupture is one of the peripartum complications that kills almost one in every thirteen mothers. However, there is limited evidence on uterine rupture trends, proportions, and determinants. Thus, this study assessed the trend, prevalence, and associated factors of uterine rupture at Nekemte Specialized Hospital, Oromia Regional State, Western Ethiopia. An institution-based cross-sectional study was conducted among 2661 clients selected using a systematic random selection technique among the data collected for the project between January 2014 and December 2022 at Nekemte Specialized Hospital. Data were collected through an interview-administered questionnaire and card review from March 2023 to August 2023. The collected data were checked, coded, and entered into Epi info version 7.2 and then exported to SPSS Version 27 for analysis. Logistic regression models were fitted to identify the factors of uterine rupture. Adjusted odds ratio with 95% Confidence Interval was estimated to measure the strength of the association, and statistical significance was declared at a p-value less than 0.05. The trend of uterine rupture declined from 1.54% in 2014 to 0.93% in 2022. The overall prevalence was 3.53% (95%CI: 2.7%, 4.3%). Low household income (Adjusted OR = 3.75, 95%CI: 1.97, 7.13), grandmultiparity (Adjusted OR = 7.78, 95%CI: 4.70, 12.88), having a history of obstetrics complications such as prolonged labor (Adjusted OR = 3.78, 95%CI:2.11, 6.75), a history of cesarean section (Adjusted OR = 2.49, 95%CI:1.42, 4.35), and history of uterine repair (Adjusted OR = 18.01, 95%CI: 6.81, 47.64) were significantly associated with uterine rupture. This finding showed that the trend is declining, and the proportion of uterine rupture is still higher. A more vigilant approach to increase access to lower-income mothers, prevent prolonged and obstructed labor, and maintain antenatal care with complete packages and a referral system are issues to be addressed to minimize the chance of uterine rupture among women.
