NCT05742737

Brief Summary

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

Study Arms (3)

Robust

Unlike previous frailty index, mFI-5 uses a small number of variables readily available in a patient's history, including functional status (partial or complete dependence), history of diabetes, COPD, congestive heart failure, and hypertension requiring medication. 1 point is assigned to each variable. Functional status refers to needing some or all of the assistance of others in daily activities, including bathing, eating, dressing, going to the toilet, moving, traveling, and more. The mFI-5 score was calculated by increasing the number of variables per patient Patients were divided into 3 groups based on their mFI-5: frail group (mFI-5, 2-5) , prefrail group (mFI-5, 1) and robust group (mFI-5, 0). The range of the mFI-5 is from 0 to 5 with increments of 1, and increasing the mFI-5 implies increasing frailty.

Study Population

The lack of sufficient study data, however, does not demonstrate a dose-response relationship, with higher frailty levels having a greater impact on mortality \[9\]. Accordingly, this article would focus on the relationship between patients with varying degrees of frailty and long-term postoperative adverse outcomes and how preoperative planning and interventions can alter surgical trajectories and associated outcomes. According to our hypothesis, preoperative frailty can provide prognostic information, in addition to frequently recognized risks and consequences.

You may qualify if:

  • (1) participants ≥ 65 years of age;

You may not qualify if:

  • lacked any covariate indicator or missing data for any confounder (such as demographic information, intraoperative surgery or anesthesia information);
  • ASA physical status Ⅴ;
  • Anesthesia other than general intravenous anesthesia or intravenous inhalation anesthesia;
  • Surgery time ≤ 60 min.
