Effects of Nurse-Led Multifactorial Care to Prevent Disability in Community-Living Older People:Cluster Randomized Trial

BackgroundTo evaluate the effects of nurse-led multifactorial care to prevent disability in community-living older people.MethodsIn a cluster randomized trail, 11 practices (n = 1,209 participants) were randomized to the intervention group, and 13 practices (n = 1,074 participants) were randomized to the control group. Participants aged >= 70 years were at increased risk of functional decline based on a score >= 2 points on the Identification of Seniors at Risk-Primary Care, ISAR-PC. Participants in the intervention group received a systematic comprehensive geriatric assessment, and individually tailored multifactorial interventions coordinated by a trained communitycare registered nurse (CCRN) with multiple follow-up home visits. The primary outcome was the participant's disability as measured by the modified Katz activities of daily living (ADL) index score (range 0-15) at one year follow-up. Secondary outcomes were health-related quality of life, hospitalization, and mortality.ResultsAt baseline, the median age was 82.7 years (IQR 77.0-87.1), the median modified Katz-ADL index score was 2 (IQR 1-5) points in the intervention group and 3 (IQR 1-5) points in the control group. The follow-up rate was 76.8% (n = 1753) after one year and was similar in both trial groups. The adjusted intervention effect on disability was -0.07 (95% confidence interval -0.22 to 0.07; p = 0.33). No intervention effects were found for the secondary outcomes.ConclusionsWe found no evidence that a one-year individualized multifactorial intervention program with nurse-led care coordination was better than the current primary care in community-living older people at increased risk of functional decline in The Netherlands.
