Abstract:
Background: According to World health organization (WHO) Postpartum
hemorrhage defined as the blood loss of more than 500 milliliters following a vaginal 
delivery or more than 1000 ml following caesarian section after placenta Deliveries. 
Postpartum hemorrhage is direct leading cause of maternal morbidity and mortality in 
the worldwide.
Objective: To determine the magnitude of postpartum hemorrhage and associated 
factors among mothers who give birth at health facilities in Ambo Town, Oromia, and 
central Ethiopia2024.
Methods: A Facility based a cross-sectional study was conducted from January 1, to 
April 30, 2024. Systematic random selected among 389 mothers who give birth at 
health facilities in Ambo Town. Data were collected using an interviewer administered, structured, and pretested questionnaire. Epi info version 7.2.5 and SPSS 
version 20 were used to enter and analyze the data, respectively. Candidate variables 
with p-value of <0.25 in bivariable Analysis were entered in to multivariable logistic 
regression analysis were done. Adjusted odds ratio with 95% confidence interval (CI) 
was used to measure the presence and strength of association between the independent 
and the outcome variables. A P-value ≤.0.05 (5%) was considered to declare 
statistical significance.
Result:-The Result of the study indicated that, the magnitude of postpartum
hemorrhage was 8.7% [95% CI: 6.2, 11.8]. Cesarean Delivery [AOR=28(5.305, 
152.37)], having Previous of postpartum hemorrhage [AOR=7.9(1.564, 39.633)], Not
attend ANC [AOR=5.5(1.101, 27.653)] and Being Age>=35 [AOR=3.1(1.3, 6.8)],
were factors significantly associated with magnitude of postpartum hemorrhage.
Conclusions and recommendation: - The magnitude of postpartum hemorrhage in 
the study area was relatively high and it results in serious postpartum mortality and 
morbidities. Caesarian section Delivery, Age of mothers >=35, Not attend Antenatal 
care, having history of Previous postpartum hemorrhage, was found to be the most 
common cause of PPH. Therefore, it is crucial to screen and closely monitor high-risk 
mothers during ANC visit, including those who have a history of cesarean delivery.
