Effect of an Institutional Triaging Algorithm on the Use of Multidetector CT for Patients with Blunt Abdominopelvic Trauma over an 8-year Period.

Purpose To evaluate the effect of an institutional clinical triaging algorithm on the rate of multidetector computed tomography (CT) utilization in blunt abdominopelvic trauma (BAPT) over an 8-year period at an urban level 1 trauma center. Materials and Methods Adult patients (n = 13 096; mean age, 42 years; age range, 15-95 years) admitted with BAPT from January 1, 2006, to December 31, 2013, were included. Patients with BAPT were divided into two groups: those admitted before (referred to as the prealgorithm group, from January 1, 2006, to June 30, 2010) and after (referred to as the postalgorithm group, from July 1, 2010, to December 31, 2013) the implementation of an institutional clinical triaging algorithm.
