Abstract:

The Connecticut Collaboration for Fall Prevention (CCFP) recently demonstrated, by comparing an intervention region to a matched region where usual care was proceeding, a significant reduction in the collective number of emergency department (ED) and hospital admissions for fall related injuries among older persons. The units of analysis in CCFP were zip code tabulation areas (ZCTAs), i.e., bounded regions, subject to spatial correlation. Here we extend the CCFP analyses with a multivariate spatial model that simultaneously considers the spatial and cross correlation of ZCTA-based rates of two distinct categories of fall-related injuries (FRI) in both regions of the CCFP. The two categories of FRI are those leading to treatment and release from the ED, and those leading to hospital admission. We then combine state and federal estimates of the mean/median costs for each category with their spatially modeled rates to estimate acute healthcare savings attributable to CCFP. This work shows how sophisticated spatial models may be used to more accurately estimate healthcare savings from interventions designed to prevent injurious falls among older persons.
