Abstract
Aims: To assess the knowledge and attitude of post- graduate medical students regarding
evidence based medicine (EBM) and to find out the barriers against its implementation, if any.
Study Design: Medical college based cross-sectional survey.
Place and Duration of Study: The study was carried out between October 2013 to March 2014,
at a medical college in Kolkata, West Bengal, India.
Methodology: Altogether 145 post-graduate medical students of clinical disciplines filled up a predesigned,
pre-tested, structured questionnaire and data were analyzed by standard statistical
procedures. Results: The mean knowledge score was found to be 13.46±3.10. The score was arbitrary, ranged
from 0 to 20 and higher score corresponded to higher knowledge. The distribution of the mean
knowledge score among <30 years (13.34±3.28) and ≥30 years (13.67±2.62) was the same across
these two categories (P =.62). Large proportions of the respondents were not familiar with reputed
EBM resources such as Cochrane data base (66.9%) and Best Evidence (67.6%). Use of Medline
was also quite poor (35.9%). Nearly half of them did not think that EBM was focused on patient’s
values and preferences and many believed that EBM would place another demand on the already
overburdened residents and doctors. Quite a large proportion thought that EBM would be of limited
value in clinical practice. However the mean attitude score (21.23±4.06) showed an overall
favorable attitude towards EBM. There was a positive correlation between the mean knowledge
and attitude scores (P =.008). The common barriers against the implementation of evidence-based
medicine were “no ready access to resources” (68.3) and “never taught on the subject” (56.6%).
Conclusion: Although many of the respondents were not adequately knowledgeable about
evidence-based medicine and also quite a few had a negative attitude towards its practicality, the
positive correlation between knowledge attitude scores suggested that imparting proper knowledge
could bring about a positive change in this attitude.
