Prevalence and predictors of primary postpartum hemorrhage: An implication for designing effective intervention at selected hospitals, Southern Ethiopia.

Background: Primary postpartum hemorrhage is the leading cause of maternal mortality worldwide. Ethiopia has made significant progress in maternal health care services. Despite this, primary postpartum hemorrhage continues to remain the leading cause of maternal mortality in Ethiopia. This study aimed to assess the prevalence and predictors of primary postpartum hemorrhage among mothers who gave birth at selected hospitals in the Southern Ethiopia.

Methods: An institution-based cross-sectional study was employed from March 2-28, 2018. Four hundred and twenty-two study participants were obtained using the consecutive sampling method. A structured interviewer-administered questionnaire and chart review were used to collect data. Data were entered into Epi-data version 3.1 and analyzed using SPSS version 22. Multivariable logistic regression were used to determine the predictors of primary postpartum hemorrhage with 95% CI and p-value < 0.05.

Results: The overall prevalence of primary postpartum hemorrhage was 16.6%. Mothers aged 35 and above [AOR = 6.8, 95% CI (3.6, 16.0)], pre-partum anemia [AOR = 5.3, 95% CI (2.2, 12.8)], complications during labor [AOR = 1.8, 95% CI (2.8, 4.2)], history of previous postpartum hemorrhage [AOR = 2.7, 95% CI (1.1, 6.8)] and instrumental delivery [AOR = 5.3, 95% CI (2.2, 12.8)] were significant predictors of primary postpartum hemorrhage.

Conclusion: Primary postpartum hemorrhage is quite common in the study area. Mothers aged 35 and above, complications during labor, history of previous postpartum hemorrhage, and instrumental delivery were predictors of primary postpartum hemorrhage. Since postpartum hemorrhage being relatively common, all obstetrics unit members should be prepared to manage mothers who experience it.
