Home alone: The role of cognition in return to independent living

Objective: To identify unique predictors of the ability to return to living alone in geriatric patients undergoing medical rehabilitation. Design: Of 900 consecutive geriatric patients entering medical rehabilitation, 372 were identified as living alone before admission. Data were collected on functional status, cognition, demographics, and discharge disposition. Setting: A freestanding medical rehabilitation facility. All patients were admitted to a geriatric rehabilitation unit. Patients: Patients aged 60 to 99, identified as having lived alone before admission, were included. As standard procedure, patients underwent functional and cognitive assessment, and medical records were reviewed. Main Outcome Measure: Logistic regression analysis was used to evaluate predictors of discharge disposition, including demographic variables, medical burden, the Functional Independence Measure (FIM), and the Dementia Rating Scale (DRS). Results: Both the FIM and DRS provided significant and unique variance in prediction of discharge disposition. Patients discharged home alone performed similarly to those discharged with supervision on FIM motor items but higher on FIM social cognition items, emphasizing the strong role of cognition in discharge disposition. Patients discharged home alone scored above suggested cutoff scores on the DRS, indicating generally intact cognitive functioning, whereas those discharged with supervision scored below suggested cutoffs. Conclusion: Results emphasize the importance of cognition in the ability to return to completely independent living after medical rehabilitation in geriatric patients.
