Résumé de la thèse

With the increasing incidence of skin cancer and limited access to specialized care, teledermoscopy (TDS) may represent a useful triage tool for skin cancer detection. Hence, we performed an evaluation of a 3-year TDS project in primary health care centers in Belgium (TELESPOT project).

A total of 9 PHCs were trained to use an inhouse developed smartphone-based application for macroscopic and dermoscopic acquisition of skin lesions, subsequently analyzed independently by two investigators in a tertiary university skin cancer center. The primary outcome was the proportion of high-priority management (HPM) recommendations.

Over 3 years, a total of 478 lesions were analyzed in 335 patients: initial phase (105 lesions from 76 patients in 6 PHCs) and extension phase (373 lesions from 259 patients in 9 PHCs). An HPM was recommended in 9.2% (initial and extension phases: 7.6% and 15.7%, respectively). The dermoscopic-histological correlation achieved 84.1%. The median delay between HPM and surgery was 9 days.

This TDS project avoided unnecessary tertiary care visits in about 9 out of 10 cases, increased the HPM by a 9-fold in comparison with the conventional care pathway and provided excellent satisfaction levels for PHCs and patients. Long-term participation improved the triage quality for suspect skin lesions by a 2.24-fold.
