    BackgroundThe aim of this study is to determine whether preoperative scores on a screening measure for cognitive status (the Saint Louis University mental status examination), were associated with discharge to a location other than home in older patients undergoing surgery for deformity.MethodsOlder patients (≥65 years) undergoing a planned elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Preoperative baseline cognition was assessed using the validated Saint Louis University mental status (SLUMS) test. SLUMS is 11 questions with a maximum of 30 points. Mild cognitive impairment was defined as a SLUMS score of 21-26 points, and severe cognitive impairment as a SLUMS score of 20 points or greater. Normal cognition was defined as a SLUMS score of 27 points or more. Postoperative length of stay and discharge location were recorded on all patients.ResultsEighty-two subjects were included, with mean ± standard deviation age of 73.26 ± 6.08 years; 51% of patients were discharged to a facility (skilled nursing or acute rehabilitation). After adjustment for demographic variables, comorbidities, and baseline cognitive impairment, patients with preoperative cognitive impairment were 4-fold more likely to be discharged to a facility (skilled nursing or acute rehabilitation) compared with patients with normal cognitive status (odds ratio [OR], 3.93). In addition, patients who were not ambulatory before surgery were also more likely to be discharged to a facility (OR, 7.14).ConclusionsIn geriatric patients undergoing surgery for deformity correction, cognitive screening before surgery can identify patients with impaired cognitive status who are less likely than those with normal cognitive status to return home after surgery.Copyright © 2017 Elsevier Inc.
