Background: Labor and delivery are unpredictable events, which can result in a disabled or a fatal state if not monitored properly. Partograph has used universally as part of safe motherhood initiative for improving and supervising labour, reducing maternal and foetal morbidity and mortality. However, its level of utilization is not clear among public health care providers in Segen area people’s zone, Southern Ethiopia. Objective: To assess partograph utilization and associated factors among public health care providers in Segen area people’s zone, southern Ethiopia. Methods: Institutional based cross-sectional study was conducted in Segen area people’s zonefrom October 1/2018 – May 15 /2019. Two hundred twenty-nine study participants were selected by simple random sampling technique from two Hospitals and twenty health centers. Quantitative data was collected by both open and closed ended questionnaire were used. Self-administered questionnaires after pre-test 5% of sample size in kelle health center in Amaro wereda, then providing training to four supervisors and eight data collectors. Binary logistic regressions analysis carried out to assess associations of selected factors with the outcome variable describe through table, graph presentation, and summation of data. Bivariate analysis used to select p-value < 0.25 were candidate for multivariate analysis then the multivariate analysis used to identify variable which independent variables affect dependent variable. Significance level and association of variables was P-value less than 0.05 computed using 95% confidence interval (CI) and COR, AOR. Result: Two hundred twenty obstetric care providers were involved in the research with a response rate of 96.1 %. The study showed that 108(49.1%), 140 (63.6%) and 174(79.1%) of respondents had utilized partograph, had knowledge and positive attitude towards partograph use respectively. Receive on job training [AOR = 4.46 (95% CI: 1.86-10.68)], having adequate knowledge [AOR = 3.82 (95% CI: 1.54-9.5)], having positive attitude [AOR = 3.61(95% CI:1.12-10.98)], working in health center [AOR = 0.19 (95% CI: 0.07-0.52)] and, availability of partograph [AOR = 2.77 (95% CI: 1.29-6.00)] were independently predictors of partograph utilization. Conclusion and Recommendation: Partograph utilization level was still poor and it may causehigh neonatal and maternal morbidity and mortality(1). Therefore, it needs deep attention for Xtraining interventions to improve the use of the partograph by health care providers. All concerned body should be continuously give on job training to obstetric care providers to develop knowledge and change attitude to use and availability on partograph utilization in health centers.
