BACKGROUND: Schizophrenia impairs a patient's self-care abilities, which are crucial after a hip fracture. Studies on the outcomes of patients with schizophrenia after a hip fracture are dated. This study aims to investigate the complication rates, 1-year mortality, and functional outcomes of surgically managed hip fractures in elderly patients with schizophrenia. METHODS: This is a retrospective, single-institution cohort study based on a prospectively maintained registry of patients with hip fracture. In this study, 3,056 patients who were ≥60 years of age were treated under a geriatric-orthopaedic hip fracture pathway from January 2014 to December 2018. Baseline demographic characteristics and the Modified Barthel Index (MBI) scores were obtained at admission and at 6 months and 1 year after the fracture. Complications from the fracture and the surgical procedure were recorded during a minimum follow-up period of 2 years. A matching process (based on age, sex, and the MBI at admission) of up to 6 patients without schizophrenia per 1 patient with schizophrenia was utilized to increase power. Differences in perioperative, 6-month, and 1-year outcomes were compared for significance among surgically managed patients with schizophrenia and patients without schizophrenia. RESULTS: Thirty-eight patients with schizophrenia were compared with 170 geriatric patients without schizophrenia who underwent a surgical procedure for a hip fracture. Patients with schizophrenia were more likely to be institutionalized postoperatively (26.3% compared with 4.7%; p < 0.001). Patients with schizophrenia had poorer MBI scores at 12 months (76 compared with 90 points; p = 0.006). The 1-year mortality rate was comparable (p = 0.29) between patients with schizophrenia (5.7%) and those without schizophrenia (2.4%). Similar trends in MBI were observed in the conservatively managed group of patients. CONCLUSIONS: There was no increase in postoperative complications after a surgical procedure for a hip fracture in elderly patients with schizophrenia. The 1-year mortality after a surgical procedure for hip fracture is similar in both patients with schizophrenia and those without schizophrenia. Patients with schizophrenia and hip fracture who were surgically managed had poorer 1-year functional outcomes compared with patients without schizophrenia matched for age, sex, and MBI at admission. This information will be useful in shared decision-making discussions with patients and families. LEVEL OF EVIDENCE: Prognostic Level III.
