Abstract

Objectives

This study was aimed to develop a pharmacovigilance practice training course for future doctors of Korean medicine, the graduate students of a college of Korean medicine, and to verify the educational effect of the curriculum.

Methods

Fifty-six students were given a training course designed as follows: 1) pre-class homework (basic theory self-study, online course, causality assessment, and adverse event reporting simulation); 2) in-class: homework submission and case discussion; 3) after-class: homework revision and resubmission. An online survey to assess the change of the level of basic knowledge and attitudes toward pharmacovigilance, the willingness to report adverse events, and self-efficacy for the causality assessment and adverse event reporting was conducted before and after education.

Results

The survey participation rate was 96.5% in pre-education and 64.3% in the post-education survey. After education, knowledge level was improved (mean score from 4.3±2.11 to 6.7±1.96 points, modal value from 3 to 8 points) and positive changes were observed in almost all questions on attitudes. In the post-education survey, more students felt that they could do causality assessment (from 13% to 80.5%), could report adverse events to the agency in charge (from 7.4% to 96.2%), and expressed their strong willingness to report adverse events in the future (from 77.8% to 88.9%) than in the pre-education survey.

Conclusions

More schools of Korean medicine need to adopt pharmacovigilance training courses in their curriculum to foster future doctors of Korean medicine with pharmacovigilance capabilities. Such efforts will be the basis for achieving an evidence-based, safe use of herbal medicine.
