Aims: This study aims to determine if a correlation exists between rehabilitation intensity, length of therapy, and standardized functional performance measures, derived from Section GG of the CARE Tool. Methods: This is a retrospective dataset analysis using descriptive and inferential statistical analysis for correlational research. The population is 943 Medicare Part A beneficiaries 65+ years of age sent to a SNF from an acute hospital stay with diagnoses of medically complex and total hip replacement. Results: Researchers used an ANOVA to determine if the change in assessment scores by levels could predict RI. Researchers found a significant correlation between the high levels of GSSC and RIOT, as well as a significant correlation between the high levels of GSMob and RIPT. Conclusions: Higher levels of therapy are correlated to increases in functional performance measure scores, indicating good support for higher levels of RI.
