ObjectivesAustralian guidelines recommend people aged 50-70 years old consider taking low-dose aspirin to reduce their risk of colorectal cancer. The aim was to design sex-specific decision aids (DAs) with clinician and consumer input, including expected frequency trees (EFTs) to communicate the risks and benefits of taking aspirin.MethodsSemi-structured interviews were conducted with clinicians. Focus groups were conducted with consumers. The interview schedules covered ease of comprehension, design, potential effects on decision-making, and approaches to implementation of the DAs. Thematic analysis was employed; independent coding by 2 researchers was inductive. Themes were developed through consensus between authors.ResultsSixty-four clinicians were interviewed over 6 months in 2019. Twelve consumers aged 50-70 years participated in two focus groups in February and March 2020. The clinicians agreed that the EFTs would be helpful to facilitate a discussion with patients but suggested including an additional estimate of the effects of aspirin on all-cause mortality. The consumers felt favourable about the DAs and suggested changes to the design and wording to ease comprehension.ConclusionDAs were designed to communicate the risks and benefits of low-dose aspirin for disease prevention. The DAs are currently being trialled in general practice to determine their impact on informed decision-making and aspirin uptake.© The Author(s) 2023. Published by Oxford University Press.
