Systematic review and meta‐analysis to estimate potential recruitment to dementia intervention studies

One in 10 people with AD or taking donepezil would, according to best available evidence, take part in industry drug trials if approached. We found no data regarding non-pharmacological intervention or pragmatic drug trial recruitment, but eligibility and participation rates for these studies are probably higher. If international studies are extrapolated to the UK, they suggest the national target of recruiting 10% of people with dementia diagnoses to research may be achieved through a nationwide policy of asking all people with dementia and their carers for consent to be approached for research participation.
