BACKGROUND The ability of an organism to withstand trauma is determined by the injury per se and inherent properties of the organism at the time of injury. We analyzed whether pre-injury morbidity scored on a four-level ordinal scale according to the American Society of Anesthesiologists Physical Status (ASA-PS) classification system predicts mortality after trauma. MATERIALS From a total of ...

OBJECTIVE To assess whether length of time on-scene in patients with major injury was associated with severity of injury or with abnormal on-scene physiology. METHODS A retrospective analysis of a convenience sample of patients in whom prehospital on-scene times were entered onto the regional major trauma database. On-scene times of patients were analysed to assess whether ultimate injury sev...

The importance and effectiveness of the appropriate use of automobile restraints by young children has been emphasized in several studies. Once the child has entered the emergency care system, however, restraint use may not be the best predictor of injury severity. This study was undertaken to investigate the relationship of restraint status to morbidity and mortality in children examined in a ...

BACKGROUND Head injury is the major cause of death in a neurosurgical patient. OBJECTIVE To find the outcome, and treatment modality affecting the outcome in patients with head injury. METHODS Nine hundred eighty seven patients presenting to National Institute of Neurological and Allied Sciences, Kathmandu, with head injury from September 2009 to October 2010 were included in the study. Pat...

Objective—To determine the performance of the ICD/AIS MAP (© E J MacKenzie et al) as a method of classifying injury severity for children. Methods—Data on all children less than 16 years of age admitted to all designated trauma centers in Pennsylvania from January 1994 through October 1996 were obtained from the state trauma registry. The ICD/AIS MAP was used to convert all injury related ICD-9...

BACKGROUND We examined the association between age, mechanism of injury, and Injury Severity Score (ISS) on mortality in major trauma. METHODS We used 9 years of population-based linked major trauma (ISS >15) registry data for Western Australia (N = 4,411). These were categorized using the Sampalis classification of injury severity: survivable (ISS 16-24), probably survivable (ISS 25-49), and...

In 2005, a major Level I trauma center closed in Los Angeles County, leading to media speculation that the sudden expansion of our catchment area would adversely affect outcome. We sought to determine whether the closure led to longer transport times and increased trauma morbidity and mortality at our Level I trauma center. Annual patient volume, paramedic transport times, injury severity score...

OBJECTIVE To determine the extent to which the Injury Severity Score (ISS) and Trauma Mortality Probability Model (T-MPM), a new trauma injury score based on empirical injury severity estimates, agree on hospital quality. DESIGN, SETTING, AND PATIENTS Retrospective cohort study based on 66,214 patients in 68 hospitals. Four risk-adjustment models based on either ISS or T-MPM were constructed,...

The objective of this report is to analyze the resource utilization and injury patterns of complex dismounted blast injuries. A retrospective review of U.S. service members injured in combat between 2007 and 2010 was conducted. Data analyzed included age, injury mechanism, amputated limbs, number and type of associated injuries, blood products utilized, intensive care unit length of stay (ILOS)...
