Frailty Index as An Indicator Associated With Postoperative Adverse Outcomes In The Older Population
Frailty Index as An Indicator Associated With Postoperative Adverse Outcomes In The Older Population
This study is a observational study in China, which aims to explore the predictive effect of preoperative frailty defined by the modified frailty index in predicting postoperative survival and complications in elderly patients.
The objectives of the study include:
1. To demonstrate that the frailty scale can predict short- and long-term survival after surgery in elderly surgical patients; 2 Demonstrated that frailty as defined by this scale is associated with postoperative complications in older patients
Traditionally, frailty has been described as the form of chronological age. Evaluating the patient's risks based solely on age is difficult, several other factors contribute to physiologic aging and determine functional reserve and response to the risk of postoperative complications. To meet the clinical demand for simpler frailty measurement tools, a simplified 5-index modified frailty index (mFI-5) has been proposed and validated in many literatures. However, there is a lack of evidence on the link between preoperative weakness and poor prognosis in elderly patients undergoing non cardiac surgery.
Therefore, the purpose of this study is to verify the prognostic value of mFI-5 for short-term and long-term adverse outcomes such as postoperative delirium, anxiety, depression, acute pain, and mortality in elderly non-cardiac surgery patients. Our hypothesis is that frailty may be highly correlated with postoperative mortality and adverse outcomes in elderly patients undergoing non-cardiac surgery, and that mFI-5 may be an effective risk prediction tool for decision-making and surgical planning.
