Evaluation of the Knowledge of Primary Care Physicians about Important Nail Diseases Before and after a Short Online Training

Nail diseases are often diagnosed late with a potential prognostic and functional impact. This could be partly due to knowledge gaps among primary care physicians (PCPs).To evaluate the knowledge about diagnosis and management of ten common/important nail conditions in a population of French PCPs and its improvement after a 31-minute online training session.We submitted 10 pre-test and post-test clinical cases and an educative online course on the diagnosis and the management of nail diseases to 138 volunteer PCPs; 73 completed the whole training path.Compared to pre-test, more PCPs in the post-test required an urgent second opinion to dermatologist for pigmented melanoma (100% versus 80.3%; P <0.05) and use of inappropriate/dangerous systemic treatment for trauma-induced nail changes was reduced after the training program (0% versus 6.8%; P <0.05). A lack of knowledge remained after training for amelanotic melanoma with an increase of mycological/bacteriological tests (9.6% versus 0%; P <0.05).Management of nail diseases by our panel of PCPs was suboptimal and was improved after a short online training.
