Abstract
To assess the effect of age-adjusted Charlson Comorbidity Index (CCI) score on Functional Independence Measure (FIM) score gain in older rehabilitation patients. This prospective cohort study observed 306 older rehabilitation patients admitted to a secondary hospital between February and April 2015. Groups were compared using CCI score cut-offs of ≤4, 5-6 and ≥ 7. Complete FIM data were available for 280 patients. The mean age-adjusted CCI score was 5.59±1.96. An age-adjusted CCI score ≤4 correlated with higher FIM scores at admission P=0.015, and discharge P=0.002, but not with a greater gain in FIM score P=0.067. There were no significant between-group differences in mortality, hospital transfers or length of stay. The Charlson age-comorbidity index was not a prognostic marker for FIM gain. Age and comorbidity alone are not barriers to the rehabilitation of older patients.
