Evaluation of the Efficacy of an Online Learning Module to Increase Wound Care Theoretical Knowledge Amongst Medical Students

Abstract

We developed and evaluated an online learning module for teaching wound care basics to junior medical learners, which was assessed for its ability to increase theoretical knowledge of wound care, and medical learners' perceptions on the use of an online module to teach wound care practices. Between February 2022 to November 2022, participants were enrolled into our unblinded, matched-pair single-arm study. Participants completed a pre- and postquiz prior to and after completing the online module, respectively. Scores on the pre- and postquiz were matched by participant and evaluated for improvement. The online module was composed of free text, animated videos with voiceovers, pictorial examples, and tables, as well as unscored knowledge checks, covering the categories of i) normal wound healing physiology, ii) describing wounds/assessment of wounds, iii) choosing dressings for wounds, and iv) addressing and understanding wound aetiologies, including diabetic, arterial, and venous ulcers. Participants were enrolled at the University of Toronto in Toronto, Canada. Participants were recruited from the undergraduate medicine and physician assistant programs at the University of Toronto. Students were provided with information on how to participate in the study through email and in-person recruitment. Thirty-three participants entered the study, and 23 participants completed the study. Across all participants, the prequiz to postquiz score increase averaged 13.29%, representing a statistically significant increase (p = 0.0000013). Ten of the 20 questions and all question categories had a statistically significant increase in the postquiz scores. All respondents found the module very useful (67%) or extremely useful (33%) for learning wound care, and 67% were very satisfied overall with the quality of the module, with the remainder (33%) of respondents somewhat satisfied. Online learning modules are effective at increasing wound care knowledge in junior medical learners, with high satisfaction amongst learners.
