Timeliness of diagnosis and treatment of cutaneous melanoma with dermatology, general practice, plastics surgery collaboration - are we meeting standards?

Abstract

Introduction Melanoma is a serious type of skin cancer with a high burden in New Zealand. MelNet Quality Statements (2021) guide the timeliness of investigations and management for melanoma patients, who might experience long delays waiting for treatment. Aim To assess compliance of melanoma diagnosis and treatment timeliness with the MelNet Quality Statements at Waikato Hospital and in primary care for melanoma and melanoma in situ (MIS). Methods This is a retrospective clinical audit of patients referred via the Suspected Skin Cancer (SSC) teledermatology pathway between June 2020 and June 2022, and histologically confirmed as having melanoma or MIS. Time intervals between elements of service were analysed. Results For 43 melanomas and 105 MIS, compliance with MelNet Quality Statements across all melanoma services was poor, except for teledermatology response rates (100% compliance). From referral to first cancer treatment (Statement 2.1.1), compliance was 50% in general practice and 7.7% in Waikato Hospital. From teledermatologist response to biopsy (Statement 2.1.3), compliance was 65.2% in general practice and 7.7% in hospital plastics department. Histopathological reporting delays were also identified. Discussion Long delays for melanoma care in hospital likely reflect system failures (such as inadequate funding and human resources) and the increasing burden of skin cancer. In contrast, primary care provided quicker diagnostic biopsies and surgical treatments for melanoma.
