Surgical intervention is important in reducing morbidity and mortality among patients admitted for small bowel obstruction (SBO). Patient-specific variables such as age and comorbidities are risk factors for adverse outcomes after surgery for SBO. However, the effect of weekend admission on outcomes has not been well delineated in the literature. Our aim was to determine whether weekend admission affects mortality and length of stay (LOS) in patients who were admitted for SBO and were managed operatively.
Using the 2006-2012 Nationwide Inpatient Sample (NIS) database, we identified adult patients who were admitted with a primary diagnosis of SBO and had a primary procedure of exploratory laparotomy, lysis of adhesions, or small bowel resection. We performed univariate analysis comparing cases that were admitted on the weekend vs. weekday. We then performed negative binomial regression with LOS as the dependent variable, adjusting for risk variables.
2804 patients were studied, of which 728 (26.0%) were admitted on the weekend. Univariate analysis showed no statistically significant difference in mortality or LOS for patients admitted on a weekday vs. weekend. Multivariate analysis showed that several factors were associated with increased LOS, including third quartile van Walraven score ( < .0001) and large hospital size ( = .0031). Other factors were associated with decreased LOS, including fourth quartile of income ( = .0022) and weekend admission ( = .048).
There is no significant difference in mortality between patients admitted on weekend vs. weekday for SBO, but patients admitted on weekend are more likely to have a decreased LOS.
