Areas of application for teledermatology

Background In recent years, the introduction of the E-Health Act and the relaxation of the ban on remote treatment has improved the framework for telemedicine in Germany. Objectives The aim of this article is to present an overview of the evidence of different areas of application for teledermatology. Materials and methods A narrative review of national and international studies and projects on the use of teledermatology for diagnosis, monitoring of diseases, triage between primary care physicians (PCPs) and dermatologists, and its use in facilities with reduced organizational and/or geographical access to specialist care was conducted. Results Diagnostic applications allow teledermatological assessment in a large proportion of cases, with high concordance of diagnosis and patient satisfaction. For the monitoring of patients, the majority of studies demonstrated no difference in effectiveness between on-site and remote consultation, while patients are spared travel distance and waiting time. For programs enabling triage most of the patients with dermatologic conditions were able to remain with the PCP, while acute patients requiring direct referral to a dermatologist were identified. In special facilities, such as prisons, dermatological teleconsultations are successfully utilized. Conclusion An adequate framework and promising evidence for the use of teledermatology exist. The areas of application are described in detail within the German S2k guideline for teledermatology. However, there is a potential risk for decreased access to telemedicine services for certain population groups.
