The most common of the included comorbidities (Table 1) was hypertension (44.9%), followed by diabetes (15.5%) and Chronic Obstructive Pulmonary Disease (COPD, 4.4%). Furthermore, 5.4% of patients experienced sepsis preoperatively. General surgery accounted for the majority of the surgical procedures with a total of 2,692,157 (45.8%) performed procedures followed by orthopedic surgery (22.0%) (Table 1 and Fig. 1). Median ASA scores were 2 for all included study years.Background Postoperative complications continue to constitute a major issue for both the healthcare system and the individual patient and are associated with inferior outcomes and higher healthcare costs. The objective of this study was to evaluate the trends of postoperative complication rates over a 7-year period. Methods The NSQIP datasets from 2012 to 2018 were used to assess 30-day complication incidence rates including mortality rate following surgical procedures within ten surgical subspecialties. Multivariable logistic regression was used to associate complication rates with dataset year, while adjusting for relevant confounders.enArticle
