Background: The use of health services by the elderly could vary according to the cultural, social, economic, and demographic situation of the person who may need the care. However, documented studies on health service utilization among the elderly population are generally scarce in Ethiopia and particularly, in the study area. Objective: This study was aimed to identify healthcare utilization and its determinants among the elderly population in Bahir Dar City, Amhara Region, Northwest Ethiopia, 2021. Methods: A community-based cross-sectional study was carried among elderly people aged 60 years and above residing in Bahir Dar city from Match 18-2April 10, 2021. The data was collected by using a structured questionnaire adopted from previous studies. Data were entered into EpiData version 4.0 and analyzed using SPSS version 25 Logistic regression analysis was carried out and all variables with a p-value less than 0.25 in the bivariate analysis were candidates for multivariable logistic regression analysis Results: Among a total of 634 study subjects planned, 625(98.6%) give their complete responses. The overall healthcare services utilization is about 64.8%. For follow-up 39.2%, getting treatment for illness 33.4% and general checkup 15.4% are the major reasons for the visit to the healthcare facility. In multivariable logistic regression model, unable to read and write [AOR =0.097; CI: 0.043-0.219], identified history of medical illness [AOR=6.634; CI: 4.159-10.582], community health insurance [AOR=14.570; CI: 7.359-27.846], monthly income less than 750 birrs [AOR= 0.166, CI: 0.047-0.582] and unable to pay for medical services [AOD= 4.358, CI: 2.545-7.462] are identified as determinants of healthcare utilization. Conclusions and Recommendations: The overall healthcare services utilization is nearly about two third that is found to be low. Health insurance, monthly income, unable to read and write, chronic diseases and unable to pay for medical service are identifiable determinants of healthcare utilization. the findings recommended that policymakers and health service providers shall identify and understand the situation of the elderly population and consequently create a conducive environment to provide appropriate healthcare services for elders.
