Question: Does liberal use of computed tomography scanning improve diagnostic accuracy in appendicitis?
Answer: The use of preoperative abdominal CT scanning has not improved the accuracy of the diagnosis of appendicitis at our institution. It has resulted in a significant increase in Emergency Department preoperative length of stay and the finding of a normal appendix at surgery. As nonsurgeons ordered the majority of preoperative CT scans, earlier input by surgeons might increase the rate of accurate clinical diagnosis and decrease the number of CT scans ordered.

no
