A cost-benefit analysis of three older adult fall prevention interventions.
INTRODUCTION One out of three persons aged 65 and older falls annually and 20 % to 30 % of falls result in injury . The purpose of this cost-benefit analysis was to identify community-based fall interventions that were feasible , effective , and provided a positive return on investment ( ROI ) . METHODS A third-party payer perspective was used to determine the costs and benefits of three effective fall interventions . Intervention effectiveness was based on r and omized controlled trial results . National data were used to estimate the average annual benefits from averting the direct medical costs of a fall . The net benefit and ROI were estimated for each of the interventions . RESULTS For the  Otago Exercise Program delivered to persons aged 65 and older , the net benefit was $ 121.85 per participant and the ROI was 36 % for each dollar invested . For Otago delivered to persons aged 80 and older , the net benefit was $ 429.18 and the ROI was 127 % . Tai chi : Moving for Better Balance had a net benefit of $ 529.86 and an ROI of 509 % and Stepping On had a net benefit of $ 134.37 and an ROI of 64 % . CONCLUSIONS All three fall interventions provided positive net benefits . The ROIs showed that the benefits not only covered the implementation costs but also exceeded the expected direct program delivery costs . These results can help health care funders and other community organizations select appropriate and effective fall interventions that also can provide positive returns on investment
