Teledermatology – Promising Technique for Improving Access to Care


Telecommunication in dermatology, known as teledermatology, can provide geographically isolated patients access to dermatology care and may be used to triage cases and limit unnecessary referrals to dermatologists. Teledermatology uses two different modalities: live interactive teledermatology, utilizing video-conference equipment, and store-and-forward teledermatology that sends still images to a dermatologist, who reviews and later provides recommendations. This article summarizes the published literature on the reliability and accuracy of teledermatology.

Teledermatology demonstrated good performance in comparison to clinic-based consultation for diagnostic agreement and diagnostic accuracy. Regarding diagnosis, teledermatologists agreed with each other and with clinic-based dermatologists at a rate comparable to group agreement among clinic dermatologists. Regarding accuracy, when compared to the gold standard of histology, rates ranged from 30% to 92% for clinic dermatologists and from 19% to 95% for teledermatologists. The authors suggest that before the widespread implementation of teledermatology, large randomized controlled trials using consistent measures of diagnostic agreement and accuracy for a wide range of skin problems and conditions are necessary to more rigorously quantify its benefits.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
