Abstract

Background: The global burden dementia is growing each year. Clinical trials investigating approaches to preventing dementia have been occurring for decades, but they are particularly challenging including the requirement to include large numbers of healthy 'at-risk' people who need to be followed up for a long period of time. Community and consumer involvement in trial design helps to ensure that the methods are acceptable to the involved stakeholders, the design and operation of clinical trials are suitable and applicable to the target population, and that key areas of concern are identified and addressed at an early stage.

Objectives: To gain insights from samples of memory clinic patients without dementia and general practitioners on the acceptability of, and attitudes towards, the proposed design of a decentralised antihypertensive dementia prevention trial. Topics addressed included the assessment of cognition, antihypertensive medication use, and motivation to participate in research.

Methods: Two focus groups (total n = 7) with memory clinic patients and individual interviews with GPs (n = 5) were conducted. Transcripts were analysed using qualitative thematic framework analysis.

Results: The proposed design was acceptable, with some possible barriers identified regarding computer use, GP time restraints, and concerns about medication interactions. Additional themes included the importance of communication and social connectedness in research participation and perceptions of ageing in medical settings. Future directions of research into larger studies and consumer-led research practices were discussed.

Conclusion: The proposed trial design was agreed to be acceptable with some operational considerations, which were incorporated in the trial design.
