Complicated Diverticulitis With Abscess Managed Nonoperatively at Index Admission: A Longitudinal Analysis of State Inpatient and Emergency Department Databases From the Healthcare Cost and Utilization Project.

Of 38,420 patients who survived an index admission for complicated diverticulitis with abscess without requiring surgical intervention, 24,214 (63.1%) were managed nonoperatively for at least 1 y following presentation.

In the nonoperative group, there was a 10.2% recurrence rate, and 88.8% had no admissions.

Patients with Medicaid (HR 0.73, CI 0.65-0.80), self-pay (HR 0.53, CI 0.47-0.59), and no charge (HR 0.56, CI 0.45-0.69) were less likely to undergo surgery than those with Medicare, while patients with private insurance were more likely.

Non-White patients were less likely to undergo surgery than White patients.
