Recruitment of older adults from long‐term care settings for a longitudinal clinical trial.

Recruitment of residents for research from long‐term care settings is known to be difficult. The purpose of this study was to summarize the effectiveness and cost in terms of time and dollars of recruitment methods for a cluster‐randomized controlled clinical trial conducted in long‐term care settings. This study was a retrospective, exploratory, descriptive analysis of recruitment data. After recruitment of 15 independent and assisted living communities, residents at each site were recruited to participate in the study using combinations of 12 different recruitment methods. Recruitment methods, time spent screening, and enrollment data were collected. Recruitment data were analyzed at the levels of site, research staff member, and participant. Over the study period, 279 older adults were screened and 172 enrolled from the 15 sites. Many participants were cognitively impaired. Research staff spent 39–89 h recruiting at each site and utilized an average of four different recruitment methods per site. Introductions of participants by site contacts yielded the most consented participants compared to other recruitment methods. Sites that had a dedicated recruiter utilized more recruiting methods and enrolled more participants than those without a dedicated recruiter. The cost of recruiting averaged $1490 per site and $93–$258 per enrollee (mean $144, standard deviation $58), but was more costly in larger facilities. Recruitment of older adults from long‐term care communities requires multiple methods of recruitment, skilled recruitment staff, and trust with the staff and potential participants.
