  • Objectives To determine the effectiveness of advance care planning (ACP) in frail older adults.

    Design Cluster randomized controlled trial.

    Setting Residential care homes in the Netherlands (N=16).

    Participants Care home residents and community‐dwelling adults receiving home care (N=201; n=101 intervention; n=100 control). Participants were 75 years and older, frail, and capable of consenting to participation.

    Intervention Adjusted Respecting Choices ACP program.

    Measurements The primary outcome was change in patient activation (Patient Activation Measure, PAM‐13) between baseline and 12‐month follow‐up. Secondary outcomes included change in quality of life (SF‐12), advance directive (AD) completion, and surrogate decision‐maker appointment. Use of medical care in the 12 months after inclusion was also assessed. Multilevel analyses were performed, controlling for clustering effects and differences in demographics.

    Results Seventy‐seven intervention participants and 83 controls completed the follow‐up assessment. There were no statistically significant differences between the intervention (–0.26±11.2) and control group (–1.43±10.6) in change scores of the PAM (p=.43) or the SF‐12. Of intervention group participants, 93% completed an AD, and 94% appointed a decision‐maker. Of control participants, 34% completed an AD, and 67% appointed a decision‐maker (p<.001). No differences in the use of medical care were found.

    Conclusions ACP did not increase levels of patient activation or quality of life but did increase completion of ADs and appointment of surrogate decision‐makers. It did not affect use of medical care.
