Abstract Aim We examinted the attitude, knowledge and perceived barriers to evidence-based practice of radiology (EBPR) among residents in radiology. Study design and setting We used the McColl questionnaire (1) and the BARRIERS scale (2) to assess the issues among radiology trainees attending an annual refresher course. Ninety six residents from 32 medical colleges from Southern India attended the course. Results Eighty (83.3%) residents, 55 male and 25 female of age range 24–34 years, consented and returned the questionnaire. The majority of the participants had a positive attitude towards EBPR. However, 45% were unaware of sources for evidence based literature although many had access to Medline (45%) and the internet (80%). The majority (70%) were aware of the common technical terms (e.g. odds ratio, absolute and relative risk) but other complex details (e.g. meta-analysis, clinical effectiveness, confidence interval, publication bias and number needed to treat) were poorly understood. Though majority of residents (59%) were currently following guidelines and protocols laid by colleagues within their departments, 70% of residents were interested in learning the skills of EBPR and were willing to appraise primary literature or systematic reviews by themselves. Insufficient time on the job to implement new ideas (70.1%); relevant literature is not being complied in one place (68.9%); not being able to understand statistical methods (68.5%) were considered to be the major barriers to EBPR. Training in critical appraisal significantly influence usage of bibliographic databases ( p < 0.0001). Attitude of collegues ( p = 0.006) influenced attitude of the trainees towards EBPR. Those with higher knowledge scores ( p = 0.02) and a greater awareness of sources for seeking evidence based literature ( p = 0.05) held stronger beliefs that EBPR significantly improved patient care. Conclusions The large knowledge gap related to EBPR suggests the need to incorporate structured training into the core-curriculum of training programmes in radiology.
