The Glasgow Coma Scale (GCS) score is widely accepted as the cornerstone in the assessment of neurologic function after trauma and is being used to select patients for enrollment in prehospital (Ph) intervention trials. This study was performed to assess the degree of agreement between Ph-GCS and emergency department (ED)-GCS scores in our trauma system patients. ⋯ In this study, differences between Ph-GCS and ED-GCS were seen in the patient population with moderate to severe head injury. Individual component score agreement was moderate for all categories, with agreement worsening for patients with longer transport times. Although this suggests improvement in the patient's condition during transport, inter-rater variability between Ph and ED personnel cannot be excluded. The utility of Ph-GCS in Ph interventional trials for determining the presence of significant head injury will need to be further evaluated.

Comparative Study
Proximal femoral nail for the treatment of reverse obliquity intertrochanteric fractures compared with gamma nail.
The reverse obliquity fracture of the proximal femur (AO/OTA 31-A3) is mechanically different from most intertrochanteric fractures. The purpose of this study was to compare the results of proximal femoral nail (PFN) fixation with those of gamma nail (GN) fixation for these fractures. ⋯ There was no difference in clinical outcome between the PFN and GN groups. However, the PFN demonstrated better results biomechanically than the GN did in terms of less sliding of lag screw, less change of neck-shaft angle, and less complications for the treatment of reverse obliquity intertrochanteric fractures.

To measure the combined contribution of change in velocity (Deltav), principal direction of force (PDOF), and restraint use on mortality after vehicular trauma. ⋯ A Deltav 40 km/h to 80 km/h, lack of restraint use, and lateral impact significantly affects mortality. A synergistic effect was found between Deltav 40-80 km/h and lateral PDOF.

Comparative Study
Range-of-motion restriction and craniofacial tissue-interface pressure from four cervical collars.
Occipital pressure ulcers are well-known complications for trauma patients wearing cervical collars. We assessed the effects of four commercial cervical collars (Aspen, Philadelphia, Miami J, and Miami J with Occian back [Miami J/Occian]) on cervical range of motion (CROM) and mandibular and occipital tissue-interface pressure (TIP). ⋯ Miami J and Philadelphia collars restricted CROM to the greatest extent. Miami J and Miami J/Occian back had the lowest levels of mandibular and occipital pressure; these collars may markedly reduce the risk of occipital pressure ulcers without compromising immobilization.

Deep vein thrombosis (DVT) is a significant cause of morbidity and mortality in trauma patients, even with appropriate prophylaxis. Many national agencies (Agency for Healthcare Research and Quality, Joint Commission, National Quality Forum) have suggested DVT incidence as a measurement of health care quality, but none has recommended a standardized screening approach. Duplex ultrasound serves an important role as a noninvasive diagnostic tool for detection of DVT. However, screening of asymptomatic patients for DVT is somewhat controversial and these practices vary widely among trauma centers. We hypothesized that as the number of screening duplex examinations in trauma patients increases, the rate of DVT identification will also increase. ⋯ Increasing the number of duplex screening exams resulted in an increased rate of DVT identification. In the absence of standardized surveillance, DVT rates may be more influenced by how often caregivers look for these events rather than the quality of care provided.
