Delivery service utilization is one of the key and proven interventions to reduce maternal death during childbearing. In Ethiopia, the utilization of health facilities for delivery service is still at a lower level. This study intends to model the determinant factors for the delivery care service utilization of childbearing mothers in Ethiopia using the 2016 Ethiopian demographic and health survey data. A cross-sectional study design was selected to assess factors associated with delivery care among mothers who had at least one child in the last 5 years before the survey aged 15-49 years in the data. Among these eligible mothers, 3,052 (27.7%) mothers had received delivery service care from health professionals. The results of multilevel logistic regression indicated that those at age 35-49 years (AOR = 0.7808, 95% CI: 0.5965-1.1132), an urban place of residence (AOR = 5.849 95% CI: 4.2755-8.0021), woman's higher level of education (AOR = 3.484, 95% CI: 2.0214-6.0038) and partner's higher educational level (AOR = 1.9335, 95% CI: 3,808-2.07352), household wealth index (AOR = 1.99, 95% CI: 1.724-2.3122), most every day exposed to mass media (AOR = 3.068, 95% CI: 1.456-6.4624), 2-4 birth order number (AOR = 0.604, 95% CI: 0.51845-1.4213), using contraceptive type (AOR = 1.4584, 95% CI: 1.2591-1.6249) and visiting more than 4 antenatal care visits (AOR = 7.574, 95% CI: 6.4824-8.84896) were more likely to give birth at a health facility compared to their counterparts. The woman's and partner's educational level, household wealth index, exposure to mass media and number of antenatal care visits had a positive association with delivery assistance whereas birth order had a negative association. The findings of this study were valuable implications to support strategies and interventions to address delivery care service in Ethiopia.
