Purpose To determine whether torso CT can be avoided in patients who experience high-energy blunt trauma but have normal vital signs. Methods High-energy blunt trauma patients with normal vital signs were retrieved retrospectively from our registry. We reviewed 1317 patients (1027 men and 290 women) and 761 (57.8%) fulfilled the inclusion criteria. All patients were initially evaluated at the emergency room (ER), with a set of tests, part of a specific protocol. Patients with at least one altered exam at initial examination or after six-hour observation received a torso CECT. Sensitivity, specificity, accuracy, positive (PPV) and negative predictive values (NPV), and likelihood ratio (LH) of the protocol were evaluated. Results Of 761 patients, 354 (46.5%) received torso CECT because of the positive ER test, with 330 being true positive and 24 being false positive. The remaining 407 patients were negative at ER tests and did not receive torso CECT, showing a significantly (P < 0.001) lower Injury Severity Score (ISS). The positive and negative LH of the protocol to detect torso injuries were respectively 16.5 and 0.01 (overall accuracy of 0.96). Conclusions Torso CT can be avoided without adverse clinical outcomes in patients who experience high-energy blunt trauma, are hemodynamically stable, and have normal initial laboratory and imaging tests.

Abstract
Purpose To determine whether torso CT can be avoided in patients who experience high-energy blunt trauma but have normal vital signs. Methods High-energy blunt trauma patients with normal vital signs were retrieved retrospectively from our registry. We reviewed 1317 patients (1027 men and 290 women) and 761 (57.8%) fulfilled the inclusion criteria. All patients were initially evaluated at the emergency room (ER), with a set of tests, part of a specific protocol. Patients with at least one altered exam at initial examination or after six-hour observation received a torso CECT. Sensitivity, specificity, accuracy, positive (PPV) and negative predictive values (NPV), and likelihood ratio (LH) of the protocol were evaluated. Results Of 761 patients, 354 (46.5%) received torso CECT because of the positive ER test, with 330 being true positive and 24 being false positive. The remaining 407 patients were negative at ER tests and did not receive torso CECT, showing a significantly (P < 0.001) lower Injury Severity Score (ISS). The positive and negative LH of the protocol to detect torso injuries were respectively 16.5 and 0.01 (overall accuracy of 0.96). Conclusions Torso CT can be avoided without adverse clinical outcomes in patients who experience high-energy blunt trauma, are hemodynamically stable, and have normal initial laboratory and imaging tests.File | Dimensione | Formato | |
