OBJECTIVES/HYPOTHESIS: OtoTrain is a Web-based otoscopy simulator that has previously been shown to have face and content validity. The objective of this study was to evaluate the effectiveness of this Web-based otoscopy simulator in teaching diagnostic otoscopy to novice learners STUDY DESIGN: Prospective, blinded randomized control trial.
METHODS: Second-year medical students were invited to participate in the study. A pretest consisted of a series of otoscopy videos followed by an open-answer format assessment pertaining to the characteristics and diagnosis of each video. Participants were then randomly divided into a control group and a simulator group. Following the pretest, both groups attended standard otology lectures, but the simulator group was additionally given unlimited access to OtoTrain for 1 week. A post-test was completed using a separate set of otoscopy videos. Tests were graded based on a comprehensive marking scheme. The pretest and post-test were anonymized, and the three evaluators were blinded to student allotment.
RESULTS: A total of 41 medical students were enrolled in the study and randomized to the control group (n = 20) and the simulator group (n = 21). There was no significant difference between the two groups on their pretest scores. With the standard otology lectures, the control group had a 31% improvement in their post-test score (mean ± standard error of the mean, 30.4 ± 1.5) compared with their pretest score (23.3 ± 1.8) (P < .001). The simulator group had the addition of OtoTrain to the otology lectures, and their score improved by 71% on their post-test (37.8 ± 1.6) compared to their pretest (22.1 ± 1.9) (P < .001). Comparing the post-test results, the simulator group had a 24% higher score than the control group (P < .002). Inter-rater reliability between the blinded evaluators was excellent (r = 0.953, P < .001).
CONCLUSIONS: The use of OtoTrain increased the diagnostic otoscopic performance in novice learners. OtoTrain may be an effective teaching adjunct for undergraduate medical students.
