Abstract:
Objective To evaluate the relationship between modified Frailty Index(mFI)and de-velopment 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 di-vided 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 in-crease in age(OR 1.068,95%CI 1.018-1.120,P=0.007),higher postoperative consumption of mor-phine(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.
