Evaluating knowledge retention and perceived benefits of medical webinar for professional development among...

To assess knowledge retention of physicians after participating in a webinar series and its perceived benefits on daily practice and career development.

The webinar series comprised six separate webinars about daily practice. Online questionnaires were sent to all participating physicians via email 3 months after the webinars. The questionnaire assessed knowledge retention through the difference between initial and follow-up post-test as well as the webinar series' benefits on daily practice and career development. Participants' demographic information, including their age, gender, education, year of graduation, and work details, were collected to compare outcomes between demographic groups.

A total of 689 responses were gathered, and 622 were analyzed. At follow-up, the median knowledge score was significantly lower than the initial median knowledge score (Z=-6.973, p<0.001). Participants' perception of the webinar series' benefits on daily practice and career development was very positive. A significant weak negative correlation was found between age and knowledge score at follow-up (rs=-0.157, p<0.001). Physicians who graduated more recently and worked for less than 3 years scored significantly higher on knowledge tests at follow-up. Meanwhile, perception score towards webinar series' benefits on daily practice was significantly higher among physicians with more extended work history. Male physicians scored significantly higher on perception score towards webinar series' benefits on career development.

Online continuing medical education programs like webinars can encourage physicians to maintain their competence, but further research on improving knowledge retention over time is necessary. Overall, physicians perceived webinars to be beneficial for their professional development.
