Background: Perioperative cardiac arrest continues to occur. This study aims to identify risk factors for perioperative cardiac arrest in children presenting for noncardiac surgery and characterise its outcomes. Methods: Using the National Surgical Quality Improvement Program (NSQIP) Pediatric Database 2019 and 2020, 261 276 patients were included. Patients ≥18 yr and cardiac surgical procedures were excluded. Exploratory multivariable analysis was performed to identify independent predictors of perioperative cardiac arrest and associated outcomes. Results: The overall rate of cardiac arrest was 0.1%, with an intraoperative rate of 0.05% and 48-h postoperative rate of 0.06%. Significant risk factors for perioperative cardiac arrest included age <12 months (adjusted odds ratios [aOR] 3.07, P<0.001), American Society of Anesthesiology Physical Status classification (ASA-PS 3 aOR=2.57, P<0.001; ASA-PS 4 aOR=5.27, P<0.001; ASA-PS 5 aOR=13.1, P<0.001), admission through the emergency room (aOR 1.7, P=0.003), inpatient (aOR 2.19, P=0.008), major and severe cardiac disease (aOR 1.58, P=0.008), impaired cognitive status (aOR 1.54, P=0.009), and longer anaesthesia duration (aOR 1.1 per 30 min, P<0.001). Perioperative cardiac arrest was significantly associated with longer hospital length of stay, reoperation, differences in discharge destination, and 30-day mortality. In addition, patients experiencing postoperative cardiac arrest had a significantly higher rate of in-hospital and 30-day mortality than those experiencing intraoperative cardiac arrest. Conclusions: The incidence of cardiac arrest in this study is higher than previously reported. This may be related to selection bias and the rigorous data collection required by NSQIP. Lower 30-day mortality after intraoperative cardiac arrest could be related to prompt recognition and rapid initiation of intraoperative resuscitation. Identification of perioperative risk factors for cardiac arrest is crucial to improve the safety and quality of patient care.
