Smartphone wallpapers for dermoscopy training in medical students and residents.

Abstract

Several dermoscopy training programs have found the accuracy of dermoscopy examination depends on adequate training of practitioners. Smartphones are readily available and time-efficient tools for dermoscopy training. To evaluate the learning efficacy of utilizing dermoscopy smartphone wallpapers to train medical students, PGY (postgraduate year)-1 trainees, and junior dermatological residents without prior dermoscopy training. We designed smartphone wallpapers with dermoscopy pictures and features of several common melanocytic and nonmelanocytic conditions. Pretests and posttests were performed before and after a 10-day-long smartphone wallpaper training program to evaluate their diagnostic accuracy using dermoscopy images. Significant progressions were noted between the pretest and posttest scores both in the nonmelanocytic (P<0.001) and the melanocytic (P=0.003) sections. Medical students and PGY-1 trainees demonstrated more significant improvement in nonmelanocytic lesions, compared to dermatology residents. Residents of dermatology showed more progression in the melanocytic section than nonresidents. There were limited participants. The frequency and time allotted by each participant in perusing the wallpapers were variable. Further study of the application on clinical practice is still needed. Smartphone wallpapers training improves dermoscopic interpretation significantly in medical students, PGY-1 trainees, and dermatological residents. The background knowledge of dermatology has an effect on the degree of improvement in the training course.
