Trial Outcomes & Findings for SpotCheck: Comparison of Enhanced Telemedicine Versus In-person Evaluation for the Diagnosis of Skin Cancer (NCT NCT04411810)

NCT ID: NCT04411810

Last Updated: 2024-04-08

Results Overview

To compare the accuracy of skin cancer diagnoses between in-person recommendation and the telemedicine (tele) recommendation, the number of "positive" evaluations (i.e. recommended for biopsy) that were truly skin cancer plus the number of "negative" evaluations (i.e. not recommended for biopsy) that were truly non-cancerous divided by the total number of skin lesions evaluated is calculated.

Participants With Skin Lesions
Participants who have up to 3 concerning skin lesions will be evaluated by both an in-person dermatologist and a team of three teledermatologists(board-certified dermatologists). The teledermatoogy team will deliver a consensus recommendation. If either the in-person dermatologist or teledermatologists are concerned that the skin spot(s) may be a skin cancer, a biopsy will be recommended and can be performed at no charge. Or if both agree that the spot(s) are not concerning for skin cancer, no biopsy will be needed.
