BackgroundDuring the initial assessment of trauma patients, the severity of injury is very often not immediately recognizable. In trauma centers, a total body CT (TBCT) scan is routinely used to evaluate this kind of patients, even if it is burdened with health risk, economical costs, and logistical difficulties.AimWe investigated the use of a clinical guide to establish a safe alternative to this routine practice.MethodsWe enrolled retrospectively 438 patients referring to the Emergency Department of Careggi University Hospital in Florence (Italy) over a 1-year period from 2014 to 2015, with the evidence of trauma and high-priority triage codes and then subjected to TBCT. We created a tool called VIBS ("Valutazione Integrata Bed Side") (from the Italian translation of "Bed Side Integrated Evaluation") which included all clinical, laboratory, and diagnostic data acquired bedside during the primary survey. Every VIBS profile was dichotomized in negative or positive if there was at least one altered item. We performed an analysis of correlation between VIBS and TBCT to determine sensibility, specificity, positive, and negative predictive value and likelihood ratio of VIBS.ResultsSensibility of VIBS in the prediction of positive CT scan was 100% and specificity was 31.7%. Positive and negative predictive value (95% C.I.) was 44.3 (38.8-49.5) and 100 (94.0-99.9). Positive and negative likelihood ratios were 1.464 and 0. Failure rate resulted in 0% and efficiency was 20.54%.ConclusionsVIBS can safely rule out severe thoracic or abdominal injuries. This approach could limit the use of TBCT in one-fifth of suspected major trauma patients.
