The IDEMCare Study-Improving Dementia Care in Black African and Caribbean Groups: A feasibility cluster randomised...

We evaluated the feasibility and acceptability of a tailored evidence-based intervention, consisting of a leaflet and a letter, to encourage timely help-seeking for dementia in Black elders.

Participating GP surgeries were randomised to send either the intervention or a control leaflet about ageing well to Black patients aged ≥50 years old without known dementia. We interviewed patients 2 weeks later about the intervention's acceptability using closed and open-ended questions, and they completed a Theory-of-Planned-behaviour questionnaire about what they would do if they developed memory problems, which they also completed 4 months later.

Five of 26 surgeries approached agreed to invite patients. Sixty-five patients responded, of whom 61 (93.8%) agreed to participate. At 2 weeks, we consented and interviewed 47/61 (77%), of whom 24 received the intervention, and at 4 months we followed up 43/47 (91.5%). At 2 weeks, 44/47 (93.6%) found either intervention acceptable to receive by post, including 23/24 of the intervention. Nineteen of 24 (79.2%) reported reading the intervention leaflet compared with 13/23 (56.5%) controls. The intervention leaflet made 16/24 (66.7%) think about visiting their doctor for memory problems and led 4 to help-seeking behaviour. We calculated that 191 patients and 24 surgeries are required for an efficacy trial.

Given the intervention is acceptable, inexpensive, and unlikely to cause harm, we judge it appropriate to disseminate it without a full-scale trial. Recruitment attainment, retention, and projected sample size calculation indicated feasibility for a larger trial.
