With improving stroke mortality rates, more individuals are living with the consequences of stroke. Obesity is a known risk factor for stroke, but its effect on functional outcomes poststroke is less clear. The aim of this study was to determine the association between body mass index classification (underweight, normal weight, overweight, and obese) and functional outcomes, as measured by Functional Independence Measure change, Functional Independence Measure efficiency, and rehabilitation length of stay after inpatient stroke rehabilitation. A retrospective cohort study of individuals with a diagnosis of stroke admitted to a high-intensity inpatient rehabilitation program was performed. Patients were divided into 4 groups based on body mass index category using normal body mass index as the reference. Overall, 34 individuals (4.5%) were classified as underweight, 303 (40.1%) had body mass indices within the normal range, 269 (35.6%) were overweight, and 149 (19.7%) were obese. Ischemic stroke was the most common stroke type across all body mass index categories. Patients in the overweight and obese groups tended to be younger. There were no statistically significant differences in rehabilitation length of stay, Functional Independence Measure change, or Functional Independence Measure efficiency with all groups demonstrating significant functional improvements. Based on these findings, patients admitted for inpatient rehabilitation after stroke can be expected to make similar functional improvements regardless of BMI class.
Objective The aim of the study was to identify factors associated with exceeding a target inpatient rehabilitation length of stay of 28 days or less for individuals with hip fracture. Design Retrospective cohort study of hip fracture patients admitted to an urban Canadian inpatient rehabilitation facility between January 1, 2013, and January 1, 2018. Patient characteristics previously shown to be associated with individual outcomes and/or length of stay after hip fracture were extracted from the institution’s data warehouse. Regression models were used to examine factors associated with exceeding target length of stay as well as overall length of stay. Results Four hundred ninety-three subjects were included in the analysis. Three hundred forty-five (70%) met and 148 (30%) exceeded their target length of stay. Patients who exceeded their target were more likely to be elderly (odds ratio, 1.05; 95% confidence interval, 1.02–1.08), to live alone prefracture (odds ratio, 1.72; 95% confidence interval, 1.02–2.91), to have dementia (odds ratio, 2.79; 95% confidence interval, 1.12–6.97), and higher admission pain scores (severe pain odds ratio, 2.51; 95% confidence interval, 1.06–5.93). Higher admission motor Functional Independence Measure scores (odds ratio, 0.95; 95% confidence interval, 0.92–0.98) were protective. Conclusions Advancing age, having dementia, living alone prefracture, and reporting moderate or severe pain at the time of admission not only increased the odds of an individual exceeding their target length of stay but also was associated with an overall increase in length of stay. Conversely, having a higher admission motor Functional Independence Measure score was protective.
