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

Purpose: To determine whether functional ability at admission and demographics predict discharge placement after inpatient rehabilitation for older adults recovering from stroke.

Method: 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.

Results: 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.

Conclusion: 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.
