Store-and-forward teledermatology in a Spanish health area significantly increases access to dermatology expertise

Teledermatology is the practice of dermatology through communication technologies. The aim of this study is to analyze its implementation in a Spanish health area during its first two years.

Cross-sectional descriptive study. It included interconsultations between dermatologists and family physicians in the Salamanca Health Area (Spain) after the implementation of the non-face-to-face modality over a period of two consecutive years. A total of 25,424 consultations were performed (20,912 face-to-face and 4,512 non-face-to-face); 1000 were selected by random sampling, half of each modality.

referral rate, response time and resolution time, type of pathology, diagnostic concordance, and quality of consultation.

The annual referral rate was 42.9/1000 inhabitants (35.3 face-to-face and 7.6 non-face- to-face). The rate of face-to-face referrals was higher in urban areas (37.1) and the rate of non- face-to-face referrals in rural areas (10.4). The response time for non-face-to-face consultations was 2.4 ± 12.7 days and 56 ± 34.8 days for face-to-face consultations (p < 0.001). The resolution rate for non-face-to-face consultations was 44%. Diagnostic concordance, assessed by the kappa index, was 0.527 for face-to-face consultations and 0.564 for non-face-to-face consultations. Greater compliance with the quality criteria in the non-attendance consultations.

Teledermatology appears to be an efficient tool in the resolution of dermatological problems, with a rapid, effective, and higher quality response for attention to skin pathologies.
