BT23 Outcomes of skin lesion referrals assessed via teledermoscopy

Abstract

Abstract Skin lesion referrals from primary care comprise a significant proportion of the dermatology workload. Urgent suspected cancer (USC) referrals are prioritized, which adds strain to outpatient capacity and impacts on waiting lists for less urgent and routine referrals. Our department provides a teledermoscopy diagnostic service to allow for timely diagnosis of skin lesions. This results in fast detection of USC and a reduction in unnecessary hospital visits for patients with benign lesions. The aim of this study was to review the outcomes of USC and routine referrals received from primary care and assessed via our teledermoscopy service. We randomly selected 381 skin lesion referrals triaged for teledermoscopy between January and March 2022. In total, 189 (49.6%) of these were referred as routine and 192 (50.4%) were urgent/USC. High-resolution clinical and dermoscopic photographs of all skin lesions were taken by qualified clinical photographers and stored in the patients’ electronic records. Two separate consultant dermatologists reviewed the images along with the information provided in the referrals for diagnosis. A total of 47 diagnoses were observed in both cohorts. Only 16% of patients referred as urgent/USC had suspected high-risk cancer, including squamous cell carcinoma (SCC; 8.8%), melanoma (5.7%) and lentigo maligna (1.5%). The remainder of urgent/USC referrals were identified as nonurgent or benign, with an overwhelmingly low risk of basal cell carcinoma (23.9%), seborrhoeic keratoses (20.8%) and benign naevi (9.3%). For routine referrals, 11 patients (5.8%) were suspected to have USC. Of these, five had histological confirmation of melanoma (n = 3), SCC (n = 1) and melanoma in situ (n = 1). Of all referrals, 44.6% were reassured and discharged; 20.8% required clinic review for a diagnostic biopsy or treatment; 20.7% were booked directly for minor surgery; 8.3% were referred to the community local enhanced services for the treatment of low-risk lesions on the torso and limbs; 1.3% were referred to other specialties; and 4.1% required digital monitoring by repeating photographs 3–6 months later. An ever-increasing prevalence of skin cancer, together with suboptimal dermatology training for primary care healthcare professionals, anxiety over misdiagnosing malignancy and pressure from anxious patients all contribute to the pressure on dermatology services. We have shown that a teledermoscopy service is a useful tool for triaging skin cancer referrals to maximize the utilization of outpatient capacity and ensure timely treatment for patients with USCs.
