Abstract:
Objective:To evaluate the relationship between modified Frailty Index (mFI) and development of delirium after artificial joint replacement in elderly patients.
Methods:Elderly patients (aged ≥60 yr) who scheduled for elective hip or knee replacement, were enrolled.Preoperative frailty was assessed using the mFI scale.All the patients received surgery under combined spinal-epidural anesthesia.Primary outcome was the incidence of delirium within 5 days after operation, and delirium was assessed by Confusion Assessment Method or Confusion Assessment Method-Intensive Care Unit.The patients were divided into delirium group and non-delirium group according to whether delirium occurred or not.
Results:A total of 620 patients were included in the study, the mFI was 0.09 (0.18), and the incidence of delirium within 5 days after surgery was 8.5%.The results of multivariate logistic regression analyses showed that increase in age (OR 1.068, 95% CI 1.018-1.120, P=0.007), higher postoperative consumption of morphine (OR 1.089, 95% CI 1.051-1.128, P<0.01) and higher mFI (OR 2.465, 95% CI 1.636-3.714, P<0.01) were the independent risk factors for postoperative delirium.
Conclusion:Higher mFI is the independent risk factor for delirium after artificial joint replacement in elderly patients.
