Clinical outcomes and operational impact of a medical photography based teledermatology service with over 8,000 patients in the UK.

A new, store-and-forward, fully digitised Teledermatology (TD) pathway was designed and implemented in an urban setting for non-two-week wait routine patients. In total 8,352 new patients had a TD consultation over 37 months. Of these, 4,748 (56.8%) were referred back to their GP, 1,634 (19.6%) were referred directly for a surgical procedure and 1,970 (23.6%) for a face-to-face review with a Dermatologist (F2F). The average waiting time for a TD appointment was 3 vs. 30 weeks for a routine F2F appointment. Between 2019 and 2018, TD referrals rose by 38%, routine dermatology referrals reduced by 16% and cancer referrals increased by 6%. Using medical photographers proved to be effective with only two cases (0.02%) of images being of insufficient quality to form a clinical opinion. Hitherto, savings for the local Commissioning Groups were estimated at £671,218. Last financial year savings (2019-2020) were £284,671. The average cost savings per TD patient appointment was £80.36. Savings in the Trust's overhead costs were £53,587. TD consultants reviewed almost twice the number of patients vs. F2F for the same amount of consultant programmed activities. 95% of surveyed patients would be likely or extremely likely to recommend this service to friends and family.
