A Randomized Clinical Trial Shows That Teledermoscopy Improves The Effectiveness Of Skin Cancer Screening

A randomized clinical trial shows that teledermoscopy improves the effectiveness of skin cancer screening

A clinical trial on teledermoscopy conducted at theDermatology Department of the Hospital Universitario Virgen Macarena of Seville, Spain has been published in the Journal of the American Academy of Dermatology (Ferrándiz L et al. Internet-based skin cancer screening using clinical images alone or in conjunction with dermoscopic images: A randomized teledermoscopy trial. J Am Acad Dermatol. 2017 Jan 12 [Epub ahead of print]).

The IMPAC-TDC Project has shown a meaningful improvement in the effectivenness and validity of the teledermatology-based skin cancer screening after the addition of dermoscopic pictures taken at the primary care center. Teledermoscopy shown a sensitivity and specificity of 93% and 96%, respectively. In addition, teledermoscopy also yielded a better cost-effectiveness ratio tan teledermatology based on clinical pictures alone.

The IMPAC-TDC Project was funded through a competitive grant from the 2013 call of the Andalusian Council of Health. Methodologically, the study involved a randomized clinical trial that compared teledermatology-based skin cancer screening suing clinical pictures along with teledermatology using clinical and dermoscopic pictures. The experimental nature applied provides a high level of evidence in favor of the implementation of teledermoscopy for the routine screening of skin cancer at the primary care centers.

This TD web platform has been developed entirely by the technological innovation team of the Dermatology Unit, TIC + Derm Group, and has been incorporated by the Ministry of Health as a corporate platform for teledermatology.

Since 2003, the Skin Cancer Program of the Hospital Universitario Virgen Macarena (Seville, Spain) offers early specialized opinion through store-and-forward teledermatology to patients presenting at the primary care center with concerning skin lesions. This teledermatology program allows a fast and direct communication between the Dermatology Unit and the 36 primary care centers pertaining to the network, with 90% of patients having a dermatologist´s opinion before 5 days since the application is submitted by the GP. Over this 13-year period, more than 65,000 people have been screened, from who more than 14.000 skin tumours and 12.800 precancerous lesions have been identified.
