Sample and recruitment
Older adults were screened for eligibility to participate in the RCT by a trained staff member of the primary care site, as described in the study protocol.Following the completion of baseline interviews, patients were randomised to receive the intervention (ie, ACHRU-CPP) in addition to usual care or usual care alone. A total of 8–10 older adults per site who completed the 6-month intervention were invited to participate in follow-up telephone interviews. Trained research assistants (MLY and RC), with no prior relationship with participants, used a telephone script to call selected older adults within 2 weeks of completing the ACHRU-CPP, to invite them to participate in a telephone interview.
