The role of patient demographics and clinical presentation in predicting discharge placement after inpatient stroke rehabilitation: analysis of a large, US data base.

Abstract

To determine whether functional ability at admission and demographics predict discharge placement after inpatient rehabilitation for older adults recovering from stroke. In this retrospective study, we examined records of 31,910 adults 65 years of age and older who were admitted for inpatient rehabilitation post-stroke. Binary logistic regression was used with the outcome of placement and potential predictors of the admission Functional Independence Measure (FIM) score, age, sex and marital status. The average admission FIM was 60.0 out of 126; the average FIM at discharge was 84.8. The mean age was 77.7 ± 7.3 years, 57% were female and 52.5% were not married. More than three quarters of the patients were discharged to home. Odds ratios (ORs) with 95% confidence intervals (CIs) showed that patients with a FIM score below the mean of our sample (OR = 5.8, CI = 5.5-6.2), older than the mean age of our sample (OR = 1.6, CI = 1.5-1.7), and who were not married (OR = 1.9, CI = 1.8-2.0) (p-values <0.001) were more likely to be discharged to residential care. Sex was not predictive of placement. The admission FIM was an important predictor of discharge placement after rehabilitation in older adults. Age and marital status were also significant predictors of discharge placement. Sex was not a significant predictor.
