This large case-control study of fall and non-fall patients in an acute-care tertiary facility was designed to concurrently test the Hendrich Fall Risk Model© (H2 Model). Cases (n=355) and controls (n=780) were randomly enrolled and assessed for more than 600 risk factors (intrinsic and extrinsic). Standardized instruments were used for key physical attributes as well as clinician assessments. A risk factor model was developed through stepwise logistic regression. Two-way interactions among the risk factors were tested for significance. The best-fitting model included 2 Log L chi square statistics, as well as sensitivity and specificity values retrospectively. The result of the study was the easy-to-use, validated H2Model, with 8 assessment parameters for high-risk fall identification tested in acute care environments.
