The Intervention Did Not Substantially Affect Costs

• No statistically significant effect on costs was detected.
• The 95-percent confidence interval for the intervention's effect on total monthly Medicare costs ranged from a $94-per-month decrease to a $130-per-month increase.
• The 95-percent confidence interval for the intervention's effect on direct injury–related Medicare costs ranged from a $12-per-month decrease to a $48-per-month increase.

Researchers Did Not Detect an Effect on the Frequency of ED Visits for Fall-Related Injuries

• No statistically significant effect on fall-related ED visits was detected.
• The 95-percent confidence interval for the estimated effect of the intervention on the incidence of fall-related injuries leading to ED visits ranged from a 26-percent reduction to a 43-percent increase (i.e., an incidence rate ratio of 0.74 to 1.43). The wide range of this estimate suggests that the study was underpowered for this outcome and that a clinically meaningful effect could have gone undetected.

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

• The model assigns each ED visit a probability weight that represents the likelihood that the visit was precipitated by a fall.
• The weights can be summed to measure the incidence of fall in a given population and time interval. They can also be used to determine the incidence of particular fall-related injuries of interest by summing the weights for ED visits during which particular injuries were diagnosed.
