Teaching dermatology to medical students: a Scoping Review of published interventional studies

It is unclear how dermatology should be optimally taught to medical students. Therefore, this scoping review was conducted aiming to identify and structure all published interventional studies that investigated dermatological teaching approaches with medical students. The methodology of this scoping review followed the PRISMA Extension for Scoping Reviews. The databases Medline and Embase were searched without restriction until 30.06.2020. A categorization and a descriptive analysis of the studies published as full articles were performed. The database search yielded 36,627 hits. 114 studies met all inclusion criteria. These came from 19 countries, were mainly published since 2010 and were distributed across 64 different journals. 32 randomized controlled trials were identified. A wide variety of teaching approaches was found, including both E-learning and conventional teaching formats. The results of the studies are presented in structured tables. This scoping review documents a large number of studies published worldwide on teaching dermatology to medical students. The teaching of dermatology appears to be successful with numerous teaching approaches, whereby interventions that incorporate didactic principles were verifiably more successful. This literature review can serve as an aid for evidence-based teaching design in dermatology as well as a basis for future research approaches.
