Examining the factors associated with past and present dermoscopy use among family physicians

INTRODUCTION: Family physicians (FPs) play a critical role in the early detection of skin cancers. Dermoscopy can improve diagnostic accuracy but its use by FPs in the United States (US) remains understudied. OBJECTIVES: To examine dermoscopy use, factors associated with ever having used (Model 1) and currently using the dermascope (Model 2), and barriers. METHODS: We recruited 705 practicing FPs in-person at conferences and on-line to complete an anonymous, 46 item survey measuring: demographic factors, physician and practice characteristics; confidence in differentiating skin lesions; knowledge and use of dermoscopy; intentions to use; and barriers to use. We conducted bivariate analysis for each outcome and entered the significant predictors into two logistic regressions. RESULTS: Almost 20% had ever used a dermascope and 8.3% were currently using it. Ever having used a dermascope was associated with being 39 years of age or younger, practicing in academia or community centers, and having higher confidence differentiating skin lesions. Current use was associated with seeing more than 400 patients per month and being 60 years-of-age or older. CONCLUSION: Use of dermoscopy by FPs is low. This study is an initial step in understanding its use among US FPs.
