A comparative evaluation of different teaching aids among fourth term medical students to improve the knowledge, attitude and perceptions about pharmacovigilance: An experimental study

Abstract

Objectives: The Study was designed to assess the awareness of Pharmacovigilance and Adverse Drug Reactions (ADRs) and to evaluate the effectiveness of different teaching aids. Materials and Methods: This was a questionnaire-based pre- and post-test on (KAP) Knowledge, Attitude, Perception about pharmacovigilance. Students were given handouts regarding pharmacovigilance and ADR reporting one week before the educational interventions. Fourth term medical students (n=72) participated in the study. They were randomly allocated into group A (n=24), group B (n=24) and group C (n=24). A pre-validated 20-point questionnaire on Pharmacovigilance and Adverse Drug Reactions (ADRs) reporting was distributed to each group of students before the educational intervention to know their awareness. The interactive educational interventions on Pharmacovigilance were given using Overhead projector (OHP) and transparencies to group A students, Black board (BB) method to group B students, Power point presentation (PPT) method to group C students respectively. Theoretical content was the same in all the educational interventions. The chi-square test and one way ANOVA was used for statistical calculation. Results: The overall response rates were expressed as percentages, MeanSD. The Mean Pre-KAP scores on knowledge was (7.70.48) but the total post- KAP scores after (OHP), (BB), and (PPT) were (12.10.39), (17.40.3), (19.40.21) respectively. The correct response rates were found to be statistically significant (P 0.001).The feedback from the students was encouraging; handouts before the class were greatly welcomed. Conclusion: The study greatly imparted knowledge about pharmacovigilanc e and ADRs reporting and students preferred power point presentations the most.
