Comparative study of video demonstration versus traditional demonstration of skills in postgraduate students of otorhinolaryngology at tertiary level rural hospital

Abstract

Introduction: Ever expanding patient expectations, increasing expense of operating room time, trainee work-hour restrictions and the application of less invasive techniques have all contributed to lessening opportunities for teaching surgical skills. Just as operating room experience is becoming more precious for residents, medical students typically receive much less teaching and evaluation of their surgical skills during their clinical rotations. Computer-assisted instruction is being used more and more to deliver educational material, particularly in medical schools. Potential reasons for adopting this technology include increased efficiency, portability, consistency, and effectiveness. Material and methods:An Interventional and Comparative study was undertaken in the Department of ENT & HNS at the tertiary level rural hospital. Total duration of the study was 24 weeks. Overall 4 procedural skills were selected. Total sample size of study was 28. Crossover was done among the groups. Both the Groups A and B were assessed by Senior Staff (Postgraduate Teacher) on the prestructured rating form of Direct Observation of Procedural Skills (DOPS.). The result among the two groups were analysed by applying unpaired t-test.Results : In DNE, 50% students were found in both satisfactory and good grading following video demonstration. In VDL, 66.70% students were found in good grading and 33.30% students were found in satisfactory grading. In EUM, 75% students were found in good grading and 25% students were found in satisfactory grading. In Mastoid Bandage, 100% students were found in good grading. Out of the total 14 students who were exposed to video demonstration showed 28.6% students having satisfactory grade and 71.40% students having good grade and no student in poor grading.Conclusion : Video Demonstration of Otorhinolaryngological Skills is a effective method of teaching and it improves attitude and professionalism in the students and enhances surgical acumen among them.
