Tai Chi: the Most Cost-effective Falls Prevention Strategy in Community-dwelling Older People
June 28, 2011
The June 2011
issue of NSW Public Health Bulletin from Australia reported a study to evaluate the cost-effectiveness of strategies
designed to prevent falls amongst people aged 65 years and over living in the
community and in residential aged-care facilities.
Methods: A systematic review and meta-analysis of the literature was
conducted. The pooled fall rate ratio was used in a decision analytic model that
combined a Markov model and decision tree to estimate the costs and outcomes of
potential interventions and/or strategies. The resulting cost per
quality-adjusted life year was estimated.
Results: The most
cost-effective falls prevention strategy in community-dwelling older people was
Tai Chi. Expedited cataract surgery and psychotropic medication withdrawal were
also found to be cost-effective; however, the effectiveness of these
interventions is less certain due to small numbers of trials and participants.
The most cost-effective falls prevention strategies in residential aged-care
facilities were medication review and vitamin D supplementation.
