Patient- and Institution-Level Factors Associated With Intraoperative Cardiac Arrest During Major Noncardiac Surgery

Despite the initial reduction in the incidence of IOCA, this study highlights a temporal increase coinciding with the COVID-19 pandemic and an increase in nonelective surgeries. Future research should explore more granular predictors of IOCA and its outcomes to develop targeted interventions for at-risk populations and tailor guidelines to manage emerging challenges in population health.
