Knowledge and Attitudes of Physicians Towards Evidence Based Medicine in Ilam, Iran

Evidence based medicine (EBM) is very important in the process of decision making, diagnosis and treatment of patients. For years, medical schools have developed instructions for EBM to determine the attitude and knowledge of physicians towards EBM and their related educational needs.. This study was a questionnaire study among physicians. One hundred twenty physicians were selected using stratified random sampling in Ilam. A main outcome measure was attitudes and knowledge of physicians toward EBM, ability to access and interpret evidence, and best method of moving from opinion based to EBM.. Of the 120 questionnaires we have sent, 94 (78.3%) were answered. 56.6% were using the internet to answer their patients questions and 23.8% used the internet to obtain clinical evidence. Mean and standard deviation (SD) of knowledge and attitude scores were 24% ± 23% and 72% ± 10%, respectively. Pearson correlation shows a significant relation between knowledge of physicians and years of graduation (r = -0.37, P = 0.00). There was a significant difference between mean of knowledge score of general practitioners, specialist and subspecialist (P = 0.026).. Knowledge and attitude of young physicians were more based on EBM compare to old physicians. A significant difference in knowledge mean score of physician shows that the EBM is still new in Iran, the future physician’s critical need to learn EBM and necessity of entering EMB at all medical levels..
