Fatal trauma: the modal distribution of time to death is a function of patient demographics and regional resources.

BACKGROUND Unlike previous studies in an urban environment, this study examines traumatic death in a geographically diverse county in the southwestern United States. METHODS All deaths from blunt and penetrating trauma between November 15, 1991, and November 14, 1993, were included. As many as 150 variables were collected on each patient, including time of injury and time of death. Initial identification of cases was through manual review of death records. Information was supplemented by review of hospital records, case reports, and prehospital encounter forms. RESULTS A total of 710 traumatic deaths were analyzed. Approximately half of the victims, 52%, were pronounced dead at the scene. Of the 48% who were hospitalized, the most frequent mechanism of injury was a fall. Neurologic dysfunction was the most common cause of death. Two distinct peaks of time were found on analysis: 23% of patients died within the first 60 minutes, and 35% of patients died at 24 to 48 hours after injury. CONCLUSIONS Although there appears to continue to be a trimodal distribution of trauma deaths in urban environments, we found the distribution to be bimodal in an environment with a higher ratio of blunt to penetrating trauma.

Telemedicine and TelepResence foR TRauma and emeRgency caRe managemenT

The use of telemedicine is long-standing, but only in recent years has it been applied to the specialities of trauma, emergency care, and surgery. Despite being relatively new, the concept of teletrauma, telepresence, and telesurgery is evolving and is being integrated into modern care of trauma and surgical patients. This paper will address the current applications of telemedicine and telepresence to trauma and emergency care as the new frontiers of telemedicine application The university Medical Center and the Arizona Telemedicine Program (ATP) in Tucson, Arizona have two functional teletrauma and emergency telemedicine programs and one ad-hoc program, the mobile telemedicine program. The Southern Arizona Telemedicine and Telepresence (SATT) program is an inter-hospital telemedicine program, while the Tucson ER-link is a link between prehospital and emergency room system, and both are built upon a successful existing award winning ATP and the technical infrastructure of the city of Tucson. These two programs represent examples of integrated and collaborative community approaches to solving the lack of trauma and emergency care issue in the region. These networks will not only be used by trauma, but also by all other medical disciplines, and as such have become an example of innovation and dedication to trauma care. The first case of trauma managed over the telemedicine trauma program or “teletrauma” was that of an 18 month- old girl who was the only survival of a car crash with three fatalities. The success of this case and the pilot project of SATT that ensued led to the development of a regional teletrauma program serving close to 1.5 million people. The telepresence of the trauma surgeon, through teletrauma, has infused confidence among local doctors and communities and is being used to identify knowledge gaps of rural health care providers and the needs for instituting new outreach educational programs.

Pediatric All-Terrain Vehicle Trauma: The Epidemic Continues Unabated

Objectives The popularity of all-terrain vehicles (ATVs) continues to increase, but this form of recreation is not as well regulated and can impact children disproportionately. This study examines the epidemiology of ATV injuries in Arizona with emphasis on pediatric injuries and compares ATV injuries to those associated with motorcycle (MCC) and motor vehicle crashes (MVC). Methods The trauma registry of a level 1 trauma center was used to identify all ATV crashes during a 5-year period (2004–2008) in patients younger than 16 years. Registration data of ATV were obtained from the state DMV. All-terrain vehicle–related injuries were compared with both MVC and MCC. Results A total of 250 pediatric ATV crashes were observed during the 5-year period, rising from 29 in 2004 to 53 in 2008. The median age of patients with ATV-related injuries was 13 years, which is higher than that of patients with MVC-related injuries (9 years). Only 34% of the patients with ATV-related injuries were helmeted, compared with 55% of patients with MCC-related injuries. All-terrain vehicle–related crashes were at least 30 times more likely than MVCs and almost 20 times more likely than MCCs. Statewide pediatric ATV deaths rose during the study period. Conclusions All-terrain vehicle–related crashes have increased during this study period and have become a significant source of injuries. Public education and awareness of the dangers associated with ATV use need to be targeted toward both parents and children likely to use ATVs.

48. Age, Sex, Ethanol Levels, and Helmet Use Among Injured Motorcyclists

Introduction : Previous studies of motorcycle injuries show that helmet use is associated with a decrease in head trauma. Understanding patterns of helmet use is important in selecting and assessing injury prevention strategies. Methods : All 470 motorcyclists presenting to either of two regional Level I trauma centers from 7/93 through 12/95 comprise this case series. Thirty-three patients were excluded due to unknown helmet use or outcome, and 50 due to age under 18 years (for whom helmet use was required by state law). Results : Of 386 patients, 42% wore helmets, and 58% did not, with no difference in the mean ages of the groups. 13% of patients were women (n = 50), and 10% were passengers (n = 38). Women were 25 times more likely than men to be passengers (95% CI: 11 to 50), and passengers were 5 times more likely than drivers to not wear a helmet (95% CI: 2 to 16). Helmet use was not related to sex, even when the data were controlled for driver vs. passenger. Of 265 patients assayed for ethanol, 30% had >100 mg/dL, 7% had p 100 mg/dL), compared to 11% of helmeted ones.
