Details and patient eligibility

About

1. To study whether there is a correlation between weakness and postoperative delusions in elderly non-cardiac surgery patients
2. Can the improved debilitating index predict the delusion after non-cardiac surgery
3. Which of the debilitating index are independent risk factors associated with postoperative delusions

Full 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.

1. To study whether there is a correlation between weakness and postoperative delusions in elderly non-cardiac surgery patients
2. Can the improved debilitating index predict the delusion after non-cardiac surgery
3. Which of the debilitating index are independent risk factors associated with postoperative delusions
