Factors Associated with Practicing Evidence-Based Medicine Among Medical Interns in Amhara Regional State Teaching Hospitals, Northwest Ethiopia: A Cross-Sectional Study

BACKGROUND: Evidence-based medicine (EBM) is an important component of modern medicine and is essential for the provision of high-quality health services. Little is known about the level of EBM use among Ethiopian medical students. This study aimed to assess the factors associated with EBM practice among medical interns in teaching hospitals in northwestern Ethiopia. METHODS: A cross-sectional study was conducted using a random sample of medical interns in teaching hospitals of northwest Ethiopia. Binary logistic regression analysis was used to identify factors associated with EBM practice. The strength of the interaction between variables was calculated using the adjusted odds ratio (AOR) with a 95% confidence interval (CI). RESULTS: Completed questionnaire was obtained from 403 (95.3%) of 423 medical interns. About 48.4% of respondents had a good EBM practice. EBM knowledge (AOR = 1.86, 95% CI = 1.220–2.835), attitude to EBM (AOR = 2.05, 95% CI = 1.318–3.193), ability to appraise evidence (AOR = 2.35, 95% CI = 1.570–3.517), and having sufficient time to search for evidence (AOR = 1.67, 95% CI = 1.065–2.627) were factors significantly associated to EBM practice. CONCLUSION: This study demonstrates that the main factors affecting medical intern’s practice of EBM were lack of critical appraisal skill, lack of knowledge needed to practice EBM, negative attitudes toward EBM, and insufficient time to search for evidence. Providing EBM training to the needs of medical interns would overcome the barriers identified in this study, as well as assist medical interns and other clinical staffs to ensure the correct application of EBM in to clinical practice.
