Prediction of an Important Finding on CT Scan

This web app will show you the estimated probability score for a clinically important finding on a CT scan performed in the Emergency Department on a patient with Crohn's disease, based on the logistic regression model from Govani, et al., from the University of Michigan which was published in Clinical Gastroenterology and Hepatology in 2014.

Govani, et al., CGH 2014; 12(10): 1702-1707

and subsequently validated at the University of Pittsburgh in 2015

Use the sliders in the left panel to select the CRP and ESR

Then decide if the clinical benefit is worth the radiation risk and cost in this patient.

No scan is recommended for scores of 0.6 or less.

The Prediction Score of a Clinically Important Finding for your values is:

The CRP value you chose in mg/LITER:

The ESR value you chose in mm/hour:
