Study Overview
Brief Summary
- To study whether there is a correlation between weakness and postoperative delusions in elderly non-cardiac surgery patients
- Can the improved debilitating index predict the delusion after non-cardiac surgery
- Which of the debilitating index are independent risk factors associated with postoperative delusions
Detailed Description
Early identification of frailty patients is of great clinical significance for preoperative decision making and prognosis assessment. To date, the incidence of postoperative delirium in elderly patients undergoing noncardiac surgery has not been assessed. This study aimed to investigate the relationship between preoperative frailty assessment and the incidence of postoperative delirium after noncardiac surgery.

Outcomes
Primary Outcomes
Postoperative Delirium
Time Frame: Twice a day from day 1 to 3 after surgery (8:00-10:00 am and 18:00-20:00 PM).
Incidence of postoperative delirium after noncardiac surgery.Postoperative delirium usually occurs between 24 hours and 72 hours after surgery, and this study will conduct follow-up assessments at six postoperative time points (once in the morning and afternoon on days 1 to 3 after surgery, 8:00 a.m.-10:00 a.m., 18:00-20:00 pm), as long as there was one time point to assess postoperative delirium, the patient was judged to have developed postoperative delirium.
Secondary Outcomes
- complications(Within 30 days after surgery)
- Incidence of 30-day readmission to hospital(Within 30 days after surgery)
