French pre-hospital trauma triage criteria: Does the "pre-hospital resuscitation" criterion provide additional benefit in triage?
OBJECTIVE
To evaluate the performance of the specific French Vittel "Pre-Hospital (PH) resuscitation" criteria in selecting polytrauma patients during the pre-hospital stage and its potential to increase the positive predictive value (PPV) of pre-hospital trauma triage.


METHODS
This was a monocentric prospective cohort study of injured adults transported by emergency medical service to a trauma center. Patients who met any of the field trauma triage criteria were considered "triage positive". Hospital data was statistically linked to pre-hospital records. The primary outcome of defining a "major trauma patient" was Injury Severity Score (ISS) > 16.


RESULTS
There were a total of 200 injured patients evaluated over a 2 years period who met at least 1 triage criterion. The number of false positives was 64 patients (ISS < 16). The PPV was 68%. The sensitivity and the negative predictive value could not be evaluated in this study since it only included patients with positive Vittel criteria. The criterion of "PH resuscitation" was present for 64 patients (32%), but 10 of them had an ISS < 16. This was statistically significant in correlation with the severity of the trauma in univariate analysis (OR = 7.2; P = 0.005; 95%CI: 1.6-31.6). However, despite this correlation the overall PPV was not significantly increased by the use of the criterion "PH resuscitation" (68% vs 67.8%).


CONCLUSIONS
The criterion of "pre-hospital resuscitation" was statistically significant with the severity of the trauma, but did not increase the PPV. The use of "pre-hospital resuscitation" criterion could be re-considered if these results are confirmed by larger studies.
