title: Diagnostic pathways and delays on route to operative intervention in acute appendicitis.
abstract: The purpose of this study was to determine the elements associated with delay in the evaluation of acute appendicitis at a community teaching hospital. We performed a retrospective chart review of patients undergoing operative exploration for presumed appendicitis in a 12-month period. Cases were categorized by the presence or absence of advanced radiographic imaging. Demographic information and time intervals from triage to operative incision were compared. One hundred twenty-four patients underwent operative exploration for presumed appendicitis. Forty-one patients had no advanced imaging, 67 had a CT scan, 8 had a sonogram, and 8 had both CT/sonogram. Patients using advanced radiographic imaging prior to operative exploration were no less likely to have a normal appendix at surgery. Diagnostic imaging significantly increased the preoperative emergency department length of stay. Two-thirds of patients with presumed acute appendicitis were imaged before operative exploration. The use of abdominal CT and sonogram resulted in significantly increased preoperative emergency department length of stay with no apparent improvement in diagnostic accuracy.
