Effects of comprehensive geriatric assessment and targeted intervention on mobility in persons aged 75 years and over: a randomized controlled trial.

OBJECTIVE

To assess the effect of a comprehensive geriatric assessment and individually tailored intervention on mobility in older people. In addition, the effectiveness of the geriatric intervention was evaluated among a subgroup of persons with musculoskeletal pain.

DESIGN

Three-year geriatric development project with randomized assignment to intervention and control group.

SETTING

Research centre, community and assisted living facilities.

PARTICIPANTS

Seven hundred and eighty-one Finnish persons aged 75-98 years were assigned to an intervention (n = 404) or control (n = 377) group.

INTERVENTION: A comprehensive geriatric assessment with a multifactorial intervention lasting two years. The intervention included individualized referrals, recommendations, physical activity counselling and supervised resistance training.

MEASUREMENTS: Perceived limitation in walking 400m was gathered annually during the intervention and at the one-year post-intervention follow-up.

RESULTS

The proportion of persons with mobility limitation at the beginning, at the two-year intervention and at the one-year post-intervention follow-up was 16%, 15%, 12% and 14%, respectively, in the intervention group. In the control group, the corresponding proportions were 19%, 18%, 23% and 26%. The treatment effect was significant at the end of the two-year intervention (odds ratio 0.82, 95% confidence interval 0.70-0.96, P = 0.013), and at the one-year post-intervention follow-up (0.84, 0.75-0.94, P = 0.002). The parallel positive effect of the intervention on mobility was even greater among persons with musculoskeletal pain.

CONCLUSION

The comprehensive geriatric assessment and individually tailored multifactorial intervention had a positive effect on mobility, underlining their importance in health promotion and disability prevention in older people.
