Sampling method
Simple random sampling technique was used to select fourteen public hospitals from eighteen public hospitals and all obstetric caregivers who were work in labor ward of selected hospital were included in the study. The sample size for dependent variable was calculated using single population proportion formula taking prevalence of labor analgesia practice(p) 0.37 from the study conducted in Kembata Tembaro zone (Geltore, Taye et al. 2018 ). By considering 5% margin of error (d) which gives n=358.The sample size for factors were calculated using EPI version 7 but the sample size for factors were less than from the sample size for calculated for dependent variable. By adding 5%, non-response rate the final sample size was 376.
Population
Source population wereall obstetric caregivers (doctors, health officers IESO, midwives, nurses) working in labor ward of public hospitals. All obstetric caregivers who were work in labor wards of selected public hospitals were study populations.

Finally, the results were in expressed terms of Adjusted Odds Ratio (AOR) and 95% confidence interval (CI). Finally, variables with p-value less to 0.05 on multivariable analysis were considered as statically significant.
