• Background Among elderly orthopedic trauma patients, the prevalence of delirium during hospitalization has been reported to be as high as 60%. Frail elderly patients have an increased risk of delirium after elective surgery; however, such an association remains underexplored among trauma patients. Aim Our goal was to investigate whether preoperative frailty is associated with postoperative delirium (POD) in elderly orthopedic trauma patients. Methods We conducted a single-center, retrospective, cross-sectional study. All patients were ≥ 65 years of age and were admitted to the hospital between 01/01/2017 and 08/31/2018 for surgical intervention of a significant extremity fracture. Frailty was assessed using the fatigue, resistance, ambulation, illness, and loss of weight questionnaire. Delirium was assessed using the Confusion Assessment Method. POD was defined as new-onset delirium that occurred within 24 h after surgery. To investigate whether frailty is associated with POD, we performed a multiple variable logistic regression, controlling for biologically relevant confounders. Results Five hundred fifty-six patients comprised the analytic cohort. Incidence of POD was 14% ( n  = 80). Multiple variable regression analysis demonstrated that each unit increment in FRAIL score was associated with a 33% higher likelihood of POD (OR 1.33; 95% CI 1.02–1.72, p  = 0.03). Conclusions Our results suggest that preoperative frailty increases the risk of POD in hospitalized, elderly, orthopedic trauma patients. Future studies are needed to determine whether perioperative interventions focused on improving frailty can reduce the risk of POD and improve outcomes in this rapidly growing cohort of patients.
