Recruitment of Older Adults With Dementia for Research: An Integrative Review.

Most included studies were retrospective and descriptive, so they show associations with recruitment numbers rather than proof that a method caused success. The studies measured success differently, such as persons contacted, screened, eligible, or enrolled, so comparison was difficult. Many studies used several recruitment methods at once, so the contribution of any single method cannot be separated. The review included only English-language studies, which may limit generalisability. The search was broadened to include mild or non-specified cognitive impairment, not only diagnosed dementia. Few studies reported limitations or validity of measures.

The supplied metadata lists NIH extramural research support. No author conflict-of-interest declaration is included in the supplied text.

Do not read this as a proven recruitment recipe or as evidence for dementia clinical care. Most studies were retrospective, used several methods together, and measured success differently, so the contribution of any single method cannot be separated.
