Abstract:

The effectiveness of individual components (other than exercise) of multifactorial intervention packages aimed to reduce the incidence of falls in older people is uncertain. There have been no randomized trials of home modifications alone for the prevention of falls. This study estimates the cost-effectiveness of just one component of a multifactorial approach to falls prevention, that is, a home hazard reduction program. The incremental cost per fall prevented was $4,986. A sensitivity analysis was conducted by removing 12 outlier subjects (6 control and 6 intervention). The incremental cost per fall prevented was $1,921 for all subjects and was cost saving for subjects who had fallen in the 12 months prior to randomization. A single factor home hazard reduction program is more likely to be most cost-effective amongst older people who have a history of falls.
