Postoperative outcomes in patients with perforated bowel: early versus late intervention

Background: Time to intervention is suggested to be a crucial factor for a number of surgical conditions. In this study, we aim to examine the postoperative outcomes associated with the timing of surgical intervention in patients with perforated bowel. Materials and methods: Cross-sectional study using the Nationwide Inpatient Sample database, 2003-2010. The study population included adult (>= 18 y) inpatients who had perforated intestine or colon and underwent bowel surgery. Results: A total of 5412 (64.6%) patients who had an early surgical intervention on same day of admission and 2985 (35.4%) patients who had a delayed surgery were included. Patients with comorbidities or those in hospitals in the Northeast region of the United States were more likely to have a delayed intervention (P < 0.01). In low-risk patients who are aged <65 y old and with no comorbidities, the timing of surgery did not associate with the risk of postoperative complications (P - 0.77) and mortality (P - 0.08), whereas in high-risk patients who are aged >= 65 y old or with comorbidities, an early surgical intervention was associated with a lower risk of complications (odds ratio: 0.77; 95% CI: 0.69-0.87; P < 0.001), and a lower mortality risk (odds ratio: 0.79; 95% CI: 0.68-0.92; P = 0.002). Patients with a delayed intervention were associated with a hospital stay >15 d (P < 0.001) and a higher cost of health services (P < 0.01). Conclusions: Patients treated in the Northeast of the United States were more likely to experience a delayed surgery. Delay of surgical intervention is associated with unfavorable outcomes only in older patients or those with comorbidities. (C) 2016 Elsevier Inc. All rights reserved.
