To investigate the association between a number of hospital level composite index methodologies developed from trauma indicators with inhospital mortality. ⋯ Trauma composite indices demonstrate construct validity when used as measures of hospital level process and represent potentially useful methods of analyzing and reporting quality indicators.

Two prospective randomized trauma trials have shown recombinant factor VIIa (rFVIIa) to be safe and to decrease transfusion requirements. rFVIIa is presently used in 22% of massively transfused civilian trauma patients. The US Military has used rFVIIa in combat trauma patients for five years, and two small studies of massively transfused patients described an association with improved outcomes. This study was undertaken to assess how deployed physicians are using rFVIIa and its impact on casualty outcomes. ⋯ In military casualties, rFVIIa is used in the most severely injured patients based on physician selection rather than on guideline criteria. Use of rFVIIa is not associated with an improvement in survival or an increase in complications. The undetected bias of physician selection of patients for treatment with rFVIIa, likely, has an impact on case matching to achieve equivalence similar to that of randomized control studies. This inability to match populations, thus, prevents definitive interpretation of this study and others studies of similar design. This problem emphasizes the need to develop entry criteria to identify patients who could potentially benefit from use of rFVIIa and the need to subsequently perform efficacy studies.

Comparative Study
The combination of an online organ and tissue registry with a public education campaign can increase the number of organs available for transplantation.
A persistent shortage of organs and inexhaustible waiting lists continue to result in many people dying while awaiting transplantation. On July 1, 2006, the California Department of Motor Vehicles joined forces with California's Online Organ and Tissue Registry and launched a campaign to increase donation rates. This campaign included intense public and media education. The efficacy of such a campaign on donor demographics has not been studied. ⋯ Public and media education significantly improved organ donor demographics. Although this study compares only 2 years before with 2 years after the donation campaign, the results are extremely favorable. Therefore, a public donation campaign and an organ donor registry are effective promotions that could help increase the number of organs available for transplantation.

Extrication collars can result in abnormal separation between vertebrae in the presence of a dissociative injury.
Cervical collars are applied to millions of trauma victims with the intent of protecting against secondary spine injuries. Adverse clinical outcomes during the management of trauma patients led to the hypothesis that extrication collars may be harmful in some cases. The literature provides indirect support for this observation. The purpose of this study was to directly evaluate cervical biomechanics after application of a cervical collar in the presence of severe neck injury. ⋯ This study was consistent with previous evidence that extrication collars can result in abnormal distraction within the upper cervical spine in the presence of a severe injury. These observations support the need to prioritize additional research to better understand the risks and benefits of cervical stabilization methods and to determine whether improved stabilization methods can help to avoid potentially harmful displacements between vertebrae.

Smoking in trauma patients: the effects on the incidence of sepsis, respiratory failure, organ failure, and mortality.
There is a high percentage of smokers among trauma patients. Cigarette smoking has been associated with the development of acute lung injury and the adult respiratory distress syndrome in critically ill patients. It is also known that nicotine exerts immunosuppressive and anti-inflammatory effects with chronic use. Trauma patients who are smokers usually go through acute nicotine withdrawal after the traumatic event and during their stay in ICU. How the smoking status and acute nicotine withdrawal affect outcomes after trauma is unknown. This question was addressed in this study by analyzing the incidence of sepsis, septic shock and multiple organ dysfunction syndrome, and other outcomes in smoking and nonsmoking trauma patients. ⋯ The smoking status plays a minimal role in the outcome of healthy trauma patients. This suggests that the acute nicotine withdrawal that usually occurs in critically ill patients has no clinically significant implications after injury.
