Indications for direct transport may be strongly related to risk of future health outcomes, and these indications may not be adequately controlled by considering only in-hospital variables. This study was designed to identify prehospital factors associated with directness of transport. ⋯ Confounding due to unadjusted prehospital factors may be present in studies evaluating the impact of directness of transport on short-term mortality outcomes. Propensity score analysis of treatment indications provides an additional and efficient method to reduce this bias.

The role of clinical examination in the diagnosis of thoracolumbar (TL) spine injuries is highly controversial. The aim of this study was to assess the sensitivity and specificity of a standardized clinical examination for diagnosing TL spine injuries after blunt trauma. ⋯ Clinical examination as a stand-alone screening tool for evaluation of the TL spine is inadequate. In this series, all the clinically significant missed fractures were diagnosed on computed tomography (CT) obtained for evaluation of the visceral torso. A combination of both clinical examination and CT screening based on mechanism will likely be required to ensure adequate sensitivity with an acceptable specificity for the diagnosis of clinically significant injuries of the TL spine. Further research is warranted, targeting the at-risk patient with a negative clinical examination, to determine what injury mechanisms warrant evaluation with a screening CT.

Benefits of high ratios of fresh frozen plasma (FFP) to packed red blood cells (pRBC) in massively transfused trauma patients have been reported previously. This study aimed to assess the effect of higher FFP:pRBC ratios on outcome in patients receiving less than massive transfusion during acute trauma care. ⋯ Trauma patients receiving less than massive transfusion might also benefit from higher FFP:pRBC ratios, as these were associated with significantly lower mortality rates and decreased blood product utilization during subsequent ICU treatment, whereas morbidity was comparable among groups. Additional prospective trials are necessary.

In light of recent data, controversy surrounds the apparent 30-day survival benefit of patients achieving a fresh frozen plasma (FFP) to packed red blood cell (PRBC) ratio of at least 1:2 in the face of massive transfusions (MT) (≥10 units of PRBC within 24 hours of admission). We hypothesized that initial studies suffer from survival bias because they do not consider early deaths secondary to uncontrolled exsanguinating hemorrhage. To help resolve this controversy, we evaluated the temporal relationship between blood product administration and mortality in civilian trauma patients receiving MT. ⋯ Improved survival was observed in patients receiving a higher plasma ratio over the first 24 hours. However, temporal analysis of mortality using shorter time periods revealed those who achieve early high-ratio are in less shock and less likely to die early from uncontrolled hemorrhage compared with those who never achieve a high-ratio. Thus, the proposed survival advantage of a high-ratio may be because of selection of those not likely to die in the first place; that is, patients die with a low-ratio not because of a low-ratio.

ACKGROUND:: Cervical spine fractures are common in traumatically injured patients. The halo-vest brace is a common treatment used for these fractures. We hypothesize that the use of halo-vest fixation is associated with a high incidence of dysphagia in trauma patients. ⋯ Patients with cervical fractures treated with halo-vest fixation have a significantly high incidence of dysphagia and aspiration. Dysphagia in trauma patients treated with halo-vests for c-spine fractures is common, associated with worse outcomes, and difficult to predict. Therefore, all of these patients should be formally evaluated for dysphagia.
