The study aimed to assess the Modified Frailty Index (MFI-5) as a tool for predicting preoperative risks in patients undergoing video-assisted thoracoscopic surgery (VATS) who are classified under the same ASA class.
It analyzed data from 69,145 patients using the American College of Surgeons' National Surgical Quality Improvement Program (NSQIP) database collected between 2008 and 2021 across various hospitals.
The results indicated that while the ASA classification alone correlated well with complications such as unplanned reintubation and prolonged ventilator dependence, combining it with MFI-5 provided an even stronger predictive capability, especially for patients classified as ASA class 3.
