Background
Early detection of melanoma represents an opportunity to reduce the burden of disease among people at increased risk for melanoma.
Objective
To develop and demonstrate the efficacy of online training.
Design
Randomized educational trial.
Participants
Primary care providers (PCPs).
Intervention
Mastery learning course with visual and dermoscopic assessment, diagnosis and management, and deliberate practice with feedback to reach a minimum passing standard.
Main Measures
Pre-test/post-test diagnostic accuracy. Referral of concerning lesions for 3 months before and after the educational intervention.
Key Results
Among the 89 PCPs, 89.8% were internal medicine physicians, and the remainder were physician assistants embedded in internists’ practices. There were no differences between control and intervention groups regarding gender, age, race, or percentage of full-time PCPs. The control group had more PCPs who reported less than 5 years of practice (n = 18) than the intervention group (n = 6) (χ2 [6, n = 89] = 14.34, p = 0.03). PCPs in the intervention group answered more melanoma detection questions correctly on the post-test (M = 10.05, SE = 1.24) compared to control group PCPs (M = 7.11, SE = 0.24), and had fewer false-positive and no false-negative melanoma diagnoses (intervention, M = 1.09, SE = 0. 20; control, M = 3.1, SE = 0.23; ANCOVA, F[1,378] =27.86, p < 0.001; ηp2 = 0.26). PCPs who underwent training referred fewer benign lesions, including nevi, seborrheic keratoses, and dermatofibromas, than control PCPs (F[1,79] = 72.89, p < 0.001; ηp2 = 0.489; F[1,79] = 25.82, p < 0.001; ηp2 = 0.246; F[1,79] = 34.25, p < 0.001; ηp2 = 0.302; respectively). Those receiving training referred significantly more melanomas than controls (F[1,79] = 24.38, p < 0.001; ηp2 = 0.236). Referred melanomas (0.8 ± 0.07 per month for intervention, 0.17 ± 0.06 for control) were mostly located on the head and neck.
Conclusions
Mastery learning improved PCPs’ ability to detect melanoma on a standardized post-test and may improve referral of patients with suspected melanoma. Further studies are needed to confirm this finding.
