结论 | The Intervention Did Not Substantially Affect Costs
Researchers Did Not Detect an Effect on the Frequency of ED Visits for Fall-Related Injuries
Researchers Developed and Validated a Model That Can Be Used to Measure the Incidence of Fall-Related ED Visits Without Relying on External Cause-of-Injury Codes

摘要 | The Office of the Assistant Secretary for Planning and Evaluation (ASPE) in the U.S. Department of Health and Human Services asked the RAND Corporation to evaluate the effectiveness of an intervention designed to prevent falls in the elderly, with a particular focus on fall-related injuries and on health care costs. ,Researchers linked data collected during a randomized trial to Medicare enrollment and claims files to compare health care costs and the frequency of fall-related emergency department (ED) visits between treatment and control groups. Using claims from both before and after trial enrollment, they adjusted for baseline differences and used intention-to-treat analyses, thereby overcoming limitations inherent in the outcome data collected during the trial. ,The researchers did not find a statistically significant effect of the intervention on costs or on the rate of fall-related ED visits. They estimate that the intervention was associated with an $18-per-month increase (95-percent confidence interval [CI] = –$94 to $130) in total health care spending, an $18-per-month increase (95-percent CI = –$12 to $48) for care directly related to injuries, and a 4-percent increase in the risk of falls (95-percent CI = 26-percent decrease to 43-percent increase). ,The researchers concluded that the fall-prevention intervention did not have a substantial effect on health care costs. Although they did not find evidence that the intervention reduced ED visits for fall-related injuries, they cautioned that the study was underpowered for this outcome and that a clinically meaningful effect could have gone undetected. |
