Risk stratification of emergency department patients with Crohn's disease could reduce computed tomography use by nearly half.

ABSTRACT:

Background & aims

Computed tomography (CT) is a useful tool for assessing disease activity and excluding complications in patients with Crohn's disease (CD). However, excessive radiation increases risk for malignancy. We aimed to identify automatable algorithms with high negative predictive values for significant CT findings in patients with CD who present at the emergency department.

Methods

We conducted a retrospective review of a tertiary center's medical records to identify adults diagnosed with CD who presented from 2000 through 2011. Logistic regression was used to model complications (perforations, abscesses, or other serious findings) and inflammation.

Results

There were 1095 visits made by 613 individuals that included a CT scan within 24 hours of arrival. Th
