A cross-sectional study evaluating the knowledge, attitude, and practice of evidence-based medicine among resident doctors of a health-care Institution of National Importance in India.

Abstract

Evidence-based medicine (EBM) promotes the integration of updated- best evidence with patient preferences and medical expertise for clinical decision-making. Despite the availability of high-quality evidence such as systematic review and meta-analysis, some clinicians manage their patients based on past experiences and expert opinion. Thus, this study was proposed to assess the knowledge, attitude, and practice of EBM among resident doctors at a tertiary care hospital in India. This cross-sectional questionnaire-based study was conducted among senior residents and final-year postgraduates (PGs) who were independently involved in clinical decision-making. By convenience sampling method, the participants were recruited, and the validated EBM Questionnaire (EBMQ) was distributed online for assessing the knowledge, attitude, and practice of EBM. Descriptive statistics were represented as frequency and proportions. A total of 102 resident doctors participated with male preponderance (74.5%). Nearly, 96 (94.1%) participants were already practicing EBM and 21.6% had undergone EBM training. Textbooks (50%) were the most often referred sources for EBM information. Specific EBM databases such as MEDLINE and Cochrane were also utilized by 37.3% of participants. More than 70% of participants understood the terms such as a randomized controlled trial, case-control study, and P value. A higher proportion (80.4%) of participants showed a positive attitude about patient care improved by EBM. The majority of the resident doctors exhibited good knowledge and a positive attitude toward applying EBM in clinical decision-making. Periodic training through workshops or courses and integration of EBM with the PG curriculum would potentially enhance the EBM practice.
