N2 - Background & Aims: Despite the increased use of anesthesia services for endoscopic procedures in the United States, the risks of anesthesia-directed sedation (ADS) are unclear. We analyzed national data from multiple centers to determine patterns of use of anesthesia services and risk factors for serious complications. Methods: We performed a cross-sectional study using the National Anesthesia Clinical Outcomes Registry, a national quality improvement database. Univariable and bivariate analyses investigated frequencies and relationships between predefined variables and serious complications of anesthesia (cardiovascular, respiratory, neurologic, drug-related, patient injury, death, or unexpected admission). A multivariable mixed-effects model determined the odds ratios between these variables and serious complications, adjusting for confounders and varying reporting practices. Results: In total, 428,947 endoscopic procedures of adults were performed using ADS from 2010 to 2015. The population was 54.9% female with a mean age of 59.1 years, and predominantly American Society of Anesthesiologists classes 2 and 3 (74.4%). More than half of the procedures were colonoscopies (51.4%); 37.4% were esophagogastroduodenoscopies and 6.5% were endoscopic retrograde cholangiopancreatographies. A total of 4441 complications (1.09%) were reported; 1349 were serious complications (0.34%). In multivariable analysis, older age, American Society of Anesthesiologists classes 4 and 5, esophagogastroduodenoscopy, general anesthesia, cases performed on an overnight shift, and longer cases were associated independently and significantly with serious complications. Conclusions: In an analysis of data from the National Anesthesia Clinical Outcomes Registry, we found ADS during endoscopy to be safe, with few serious complications (<1% of procedures). Risk of ADS complications increased with older age, more severe disease, procedure type, and case complexity.
