AI-Summary
What this Trial Is About
The proportion of noncardiac surgeries performed as same-day surgery is increasing worldwide, with more complex surgeries being performed on higher risk patients in the outpatient setting. Little is known on the risk factors, incidence and prognosis of patients undergoing same-day noncardiac surgery. The main objective of this study is to inform on the incidence and risk factors of cardiovascular and other adverse events after same-day surgery and to develop risk prediction tools to better inform on the risk and selection of patients undergoing same-day surgery.
