Feasible Model for Prevention of Functional Decline in Older People: Municipality‐Randomized, Controlled Trial

Abstract

To investigate the effect of an educational program for preventive healthcare professionals in routine primary care on functional ability, nursing home admissions, and mortality in older adults. A prospective, controlled 3-year follow-up study (1999-2001) in primary care with randomization and intervention at the municipality level and outcomes measured at the individual level in two age cohorts. Primary care. Of 81 eligible municipalities in four counties, 34 agreed to participate. A total study population of 5,788 home-dwelling subjects aged 75 and 80 were asked to participate. Written consent was obtained from 4,060 persons (70.1%), of whom 2,104 were living in 17 intervention municipalities and 1,956 were living in 17 matched control municipalities. Intervention municipality visitors received ongoing education, and local general practitioners were introduced to a short geriatric assessment program early in the study period. Control municipalities visitors and general practitioners received no education. At the 3-year follow-up, the outcome measures of mortality and nursing home admissions were obtained from all, and the outcome measure of functional ability was obtained from 3,383 (95.6%) of 3,540 surviving participants. Education improved functional ability (odds ratio=1.20, 95% confidence interval (CI)=1.01-1.42, P=.04) in intervention municipality participants, notably in the 80-year-olds. There were no differences in mortality (relative risk (RR)=1.06, 95% CI=0.87-1.28, P=.59) or rates of nursing home admissions after 3 years (RR=0.74, 95% CI=0.50-1.09, P=.13). Subjects aged 80 benefited from accepting and receiving in-home assessment with regular follow-ups. A brief, feasible educational program for primary care professionals helps preserve older people's functional ability.
