Competency in evidence-based medicine and associated factors among medical radiology technologists in Addis Ababa, Ethiopia

Abstract

Introduction: Evidence-based medicine integrates clinical expertise, patient values and best research evidence in clinical decision-making. This study aimed to assess evidence-based medicine knowledge, attitudes, practices and associated factors among medical radiology technologists in Addis Ababa, Ethiopia. Methods: A cross-sectional study was conducted among 392 medical radiology technologists from May to August 2022 using a self-administered questionnaire. Bivariate and multivariate logistic regression identified factors associated with evidence-based medicine practice. Results: Most medical radiology technologists (57.7%) had moderate evidence-based medicine knowledge and 94.9% had favourable attitudes. However, 64.8% demonstrated poor evidence-based medicine practice. Factors significantly associated with better evidence-based medicine practice were moderate knowledge (AOR 1.949, 95% CI 1.155–3.291), good statistical understanding (AOR 1.824, 95% CI 1.135–2.930), sufficient time for evidence-based medicine (AOR 1.892, 95% CI 1.140–3.141), institutional support (AOR 2.093, 95% CI 1.271–3.440) and evidence-based medicine resource access (AOR 1.653, 95% CI 1.028–2.656). Conclusion: Despite moderate knowledge and positive attitudes towards evidence-based medicine, most medical radiology technologists had suboptimal utilisation. Strategies to improve knowledge, ensure dedicated time, provide institutional support and resources could enhance evidence-based radiology practice.
