Specialised surveillance using total body photography and digital dermoscopy to monitor people at very high risk of developing a second or subsequent melanoma has been reported as cost effective.
We aimed to estimate the 5-year healthcare budget impact of providing specialised surveillance for people at very high risk of subsequent melanoma from the perspective of the Australian healthcare system.
A budget impact model was constructed to assess the costs of monitoring and potential savings compared with current routine care based on identification of patients at the time of a melanoma diagnosis. We used data from a published cost-effectiveness analysis of specialised surveillance, and Cancer Registry data, to estimate the patient population and healthcare costs for 2017–2021.
When all eligible patients, estimated at 18% of patients with melanoma diagnosed annually in Australia, received specialised surveillance rather than routine care, the cumulative 5-year cost was estimated at $93.5 million Australian dollars ($AU) ($US 64 million) for specialised surveillance compared with $AU 120.7 million ($US 82.7 million) for routine care, delivering savings of $AU 27.2 million ($US 18.6 million). With a staggered introduction of 60% of eligible patients accessing surveillance in year 1, increasing to 90% in years 4 and 5, the cumulative cost over 5 years was estimated at $AU 98.1 million ($US 67.2 million), amounting to savings of $AU 22.6 million ($US 15.5 million) compared with routine care.
Specialised melanoma surveillance is likely to provide substantial cost savings for the Australian healthcare system.
