Earlier cancer diagnosis in primary care: a feasibility economic analysis of ThinkCancer!

Background: UK cancer survival rates are much lower compared with other high- income countries. In primary care, there are opportunities for GPs and other healthcare professionals to act more quickly in response to presented symptoms that might represent cancer. ThinkCancer! is a complex behaviour change intervention aimed at primary care practice teams to improve the timely diagnosis of cancer. Aim: To explore the costs of delivering the ThinkCancer! intervention to expedite cancer diagnosis in primary care. Design & setting: Feasibility economic analysis using a micro- costing approach, which was undertaken in 19 general practices in Wales, UK. Method: From an NHS perspective, micro- costing methodology was used to determine whether it was feasible to gather sufficient economic data to cost the ThinkCancer! intervention. Owing to the COVID- 19 pandemic, ThinkCancer! was mainly delivered remotely online in a digital format. Budget impact analysis (BIA) and sensitivity analysis were conducted to explore the costs of face- to- face delivery of the ThinkCancer! intervention as intended pre- COVID- 19. Results: The total costs of delivering the ThinkCancer! intervention across 19 general practices in Wales was 25 pound 030, with an average cost per practice of 1317 pound (standard deviation [SD]: 578.2). Findings from the BIA indicated a total cost of 34 pound 630 for face- to- face delivery. Conclusion: Data collection methods were successful in gathering sufficient health economics data to cost the ThinkCancer! intervention. Results of this feasibility study will be used to inform a future definitive economic evaluation alongside a pragmatic randomised controlled trial (RCT).
