Trends in pediatric non-operating room anesthesia: Data from the National Anesthesia Clinical Outcomes Registry

Background: Modern pediatric anesthetic encounters occur in operating rooms and non-operating room settings. Most anesthesia providers have cared for children in radiology, endoscopy, and other interventional settings at some point in their training and career. There is an absence of published data on the frequency, timing, and demographics of these pediatric anesthesia encounters.Aims: The primary goal of our study is to present data spanning a variety of institutions and practice settings in the United States to define the percentage of non-operating room anesthetic encounters in children. We also set out to characterize the frequency of the most common procedures in the non-operating room setting within the United States.Methods: Using the National Anesthesia Clinical Outcomes Registry data from 2015-2019, we analyzed and reported data on current trends in non-operating room anesthesia including patient demographics, encounter setting, procedure type, and the time at which anesthetic encounters occurred.Results:2236 788 pediatric anesthetic encounters (patient age < 18 y.o.) were analyzed revealing that 22.7% of all pediatric anesthetics occur in non-operating room settings. Patients were more likely to have higher American Society of Anesthesiologists Physical Status classifications in the non-operating room anesthesia group. Gastroenterological suites are the most common setting reported for pediatric non-operating room anesthesia.Conclusions: Non-operating room anesthesia in the United States is a prominent segment of pediatric anesthetic practice. Pediatric patients encountered in the non-operating room setting have more comorbidities, though further studies are needed to characterize the implication of this finding.
