Role of frailty in predicting postoperative pulmonary complications in older patients undergoing major abdominal surgery: a retrospective cohort study.

ABSTRACT:

Background

This study aimed to determine the association between frailty, as measured by the five-item modified frailty index (mFI-5), and postoperative pulmonary complications (PPCs) in older patients undergoing major abdominal surgery and to explore the predictive value of frailty beyond traditional PPC risk factors.

Methods

In this retrospective cohort study, we collected baseline and perioperative data of older patients (aged ≥ 65 years) undergoing major abdominal surgery in a tertiary hospital. The association between the mFI-5 score and PPCs was examined using multivariate logistic regression analysis. Additionally, the predictive value of the mFI-5 beyond the four basic PPC risk models was estimated using discrimination (areas under receiver operating characteristic c
