Knowledge and attitude toward evidence-based medicine and associated factors among medical interns in amhara regional state teaching hospitals, northwest ethiopia: Cross-sectional study

Abstract

Background: Evidence-based medicine (EBM) is widely accepted in medicine. It is necessary to improve the knowledge and attitudes of medical students in the use of evidence. In Ethiopia, little is known about medical students' knowledge and attitudes toward EBM. Objective: This study aimed to assess the knowledge and attitudes toward EBM and its associated factors among medical interns in teaching hospitals. Methods: A cross-sectional survey was conducted using a random sample of medical interns in teaching hospitals in Ethiopia. Multivariable logistic regression analyses were used to identify the factors associated with the knowledge and attitudes toward EBM. Adjusted odds ratio (AOR) with 95% confidence interval and P≤.05 was used to quantify strength of association between variables. Results: Out of a sample of 423 medical interns, 403 completed the questionnaire (95.3% response rate). Overall, 68.0% (274/403 of respondents had a favorable attitude toward EBM and 57.1% (230/403) had good knowledge of EBM. The majority (355/403, 88.1%) of participants had internet access. Only 19.6% (79/403) of respondents had received EBM-related training. Respondents' knowledge of EBM was associated with previous EBM training (AOR 2.947, 95% CI 1.648-5.268, P
