ABSTRACT
BACKGROUND:
The aim of this study was to determine whether time to surgery after an initial episode of uncomplicated diverticulitis is associated with undergoing an emergent versus an elective resection.METHODS:
In this retrospective, administrative claims database study, we identified patients at least 18 y old in the 2005-2011 California State Inpatient Database who had an initial episode of uncomplicated diverticulitis and then underwent a bowel resection within 2 y. After characterizing the distribution in time to surgery among all patients, we used a multivariable logistic regression to determine whether time to surgery was associated with undergoing an emergent resection. Next, we assessed differences in three outcomes between elective and emergent resections at least one of eight postoperative complications, extended length of stay (defined as the top decile of hospitalizations), and 30-d inpatient readmissions. Analyses adjusted for time between initial hospitalization and resection, number of inpatient hospitalizations for diverticulitis before the resection, clinical factors, and hospital clustering.RESULTS:
We identified 4478 patients with an initial episode of uncomplicated diverticulitis followed by a bowel resection within the subsequent 2 y. One-fifth (21.1%) underwent an emergent resection. The median time from the initial episode to resection was 3.8 mo (IQR 2.3-8.1 mo) for elective resections and 5.1 mo (IQR 2.3-12.4 mo) for emergent resections. The adjusted odds of undergoing an emergent relative to an elective resection increased by 7% (aOR 1.07 [1.02-1.11]) for every 3 passing mo. Emergent resections were associated with greater adjusted odds of complications (adjusted odds ratio [aOR] 1.75 [95%-CI 1.43-2.15]), extended LOS (aOR 4.52 [3.31-6.17]), and 30-d readmissions (aOR 1.49 [1.09-2.04]).CONCLUSIONS:
Among patients who experienced an initial episode of uncomplicated diverticulitis and eventually underwent a resection, the odds of having an emergent relative to elective surgery increased with every 3 passing mo. These findings may inform the management of uncomplicated diverticulitis for high-risk patients eventually needing surgery.Key words
