Impact of Preoperative Functional Capacity on Postoperative Mortality and Morbidity: A Prospective Cohort Study.

ABSTRACT:

Background

Functional capacity is an important determinant of surgical risk, yet the relationship between self-reported metabolic equivalents of task (MET) levels, treated as a multilevel variable, and postoperative outcomes remains unclear. This study evaluated the association between categorized MET levels and short- and long-term mortality and morbidity.

Methods

This dual-center prospective cohort study enrolled adults undergoing elective noncardiac surgery at Karolinska University Hospital (Solna and Huddinge, Sweden) between 2020 and 2023, excluding obstetric, transplant, day surgery, and nonoperative cases. Preoperative functional capacity was assessed in MET categories (1, 2 to 3, 4 to 5, 6 to 8, 9 or greater). Primary outcomes were all-cause mortality at 30 and 365 d
