Impact of Unenhanced Computed Tomography (CT) in Elderly Patients Admitted to the Emergency Department With Acute Abdominal Pain

Accuracy of Unenhanced CT in Elderly Patients Admitted to the Emergency Department With Acute Abdominal Symptoms


Lead Sponsor: University Hospital, Montpellier

Source University Hospital, Montpellier
Brief Summary

The purpose of this study is to determine whether non-contrast abdominal computed tomography (CT) impacts management (diagnosis, need for surgery and treatment) in elderly patients admitted to the emergency department with abdominal pain.

Detailed Description

A systematic unenhanced abdominal CT is performed in elderly patients admitted to the emergency patients with acute abdominal symptoms. Accuracy of unenhanced CT is assessed by comparing diagnosis and therapeutic management recorded before and after unenhanced CT versus gold standard diagnosis and management. Gold standard diagnosis and management are established at 3 month follow up, based on patient's medical records and a systematic telephone interview.
