Diagnostic spectrum and therapeutic efficiency in teledermatology-Results of the largest cohort study to date.

Timely and comprehensive dermatological care is a major challenge. Digitized medical consultation offers a possibility to overcome this problem. Here, we studied the diagnostic spectrum and treatment success in teledermatology in the largest cohort to date. Over 12 months, 21 725 individuals received a diagnosis and therapeutic advice using the asynchronous image-text method. In the context of quality management, 1802 individuals (~10%) of both sexes with a mean age of 33.7 years (SD 15.36) received a follow-up 3 months after the initial consultation to assess the treatment outcome. Of these, 81.2% did not require a face-to-face consultation. Therapeutic efficiency could be ascertained in 83.3% of the patients, whereas 10.9% did not improve, and 5.8% did not provide an information on the course of therapy. Teledermatology is a useful tool in digitalized medicine and complements the classical in-person dermatological examination, as shown by the high degree of treatment efficacy in this study. Although face-to-face consultations can not and should not be completely substituted by teledermatology it reflects a significant contribution to patient care and justifies the further expansion of digital structures in dermatological care.
