BACKGROUND: The optimal timing of appendectomy for acute appendicitis has been analyzed with mixed results. We hypothesized that delayed appendectomy would be associated with increased 30-d morbidity and mortality. MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients undergoing nonelective appendectomy from 2012 to 2015 with a postoperative diagnosis of appendicitis. Patients were grouped based on hospital day (HD) of operation. Primary outcomes included 30-d mortality and major complications. Logistic regression was performed to determine predictors of major morbidity and mortality. RESULTS: From 2012 to 2015, 112,122 patients underwent appendectomy for acute appendicitis. Appendectomies performed on HD 3 had significantly worse outcomes as demonstrated by increased 30-d mortality (0.6%) and all major postoperative complications (8%) in comparison with operations taking place on HD 1 (0.1%; 3.4%) or HD 2 (0.1%, P < 0.001; 3.6%, P < 0.001). In subgroup analysis, open operations had significantly higher mortality and major postoperative complications, including organ/space surgical site infections (4.6% open versus 2.1% laparoscopic; P < 0.001). Patients with decreased baseline physical status by the American Society of Anesthesiologists Physical Status class had the worst outcomes (1.5% mortality; 14% major complications) when operation was delayed to HD 3. Logistic regression revealed higher American Society of Anesthesiologists Physical Status class and open operations as predictors of major complications; however, HD was not (P = 0.2). CONCLUSIONS: Data from the American College of Surgeons National Surgical Quality Improvement Program demonstrate similar outcomes of appendectomy for acute appendicitis when the operation is performed on HD 1 or 2; however, outcomes are significantly worse for appendectomies delayed until HD 3. Increased complications in this group are likely not attributable to HD of operation, but rather decreased baseline health status and procedure type.
