Effect of British=made videotapes on clinical performance of medical students in Pakistan

Abstract

The efficacy of videotapes, recorded in Cardiff, in improving the clinical performance of final-year medical students in Abbottabad (Pakistan) was tested, by carrying out a structured, stepwise, clinical assessment before and after video teaching in 32 students. All students examined eight systems/subsystems at eight stations and spent 5 min with each patient, during which their performance was checked against structured check-lists by eight examiners. These students had not received any clinical instruction from a specialist rheumatologist, neurologist or endocrinologist during their clinical apprenticeship. Before the video teaching they performed poorly when examining the knee joint, motor system, hands and thyroid status, but when tested again 2 days after video teaching, there was a transformation in their clinical behaviour and their mean (s.d.) score improved from 40 (6.6 per cent) to 57.6 (9.4 per cent; P=0.001). In contrast to their pre-video performance, they interacted well with the patients and examiners providing a running commentary of their findings, as demonstrated in the videotapes. Among the residual problems were a poor technique of testing tendon reflexes and percussion. All the examiners and 21 of 32 students thought that the structured examination was fairer than the conventional examination. Of the 32 students, 20 thought that video teaching was less effective than personal bedside teaching, while 12 students thought that video was structured better than bedside instruction. All students would welcome viodeo teaching to supplement their existing teaching and would like the structured examination introduced to their curriculum. This study suggests that videotaped demonstrations can be used effectively in transmitting clinical skills to students not exposed to clinical teaching by specialists in various subjects.
