Newer studies have hypothesised about a coagulopathy that occurs early after trauma, early trauma induced coagulopathy, ETIC, and is defined by an elevated admission prothrombin time (PT). Also, referred to by some authors as acute traumatic coagulopathy, it has been most often studied in cohorts of severely injured or hypotensive patients. However, we wanted to prospectively investigate ETIC in a large all-comers cohort to confirm its prevalence across the entire spectrum of injury, to evaluate its risk pattern and to determine a possible relationship to reduced survival. ⋯ ETIC is an early, primary post-injury coagulopathy that occurs in 16.3% of admitted trauma patients. It is associated with an increase in mortality, even when controlling for crystalloids, vital signs, injury severity and head injury. It can also be found in approximately 11% of mildly injured patients (patients without physiological derangement or blood product administration). Therefore, further elucidation of ETIC is strategic to impacting trauma patient outcome.

Comparative Study
Outcome of penetrating intracranial injuries in a military setting.
Penetrating intracranial injuries are common in the deployed military medical environment. Early assessment of prognosis includes initial conscious level. There has been no previous identification of different outcomes depending on mechanism of penetrating injury. The aim of this study was to define outcome from penetrating head injury in our population, and to compare outcome between gunshot wound (GSW) and blast fragment injury, in order to detect a difference in survival. ⋯ Most patients who present following penetrating intracranial injury, who have a GCS>5, survive to discharge. There is a significant difference in survival to hospital discharge following penetrating injury caused by blast fragment compared to those caused by GSW, partly attributable to a difference in injury severity. This is the first study to specifically highlight and define this difference.

Quality improvement programmes are an important part of care delivery in trauma centres. The objective was to describe the effect of a comprehensive quality improvement programme on long term patient outcome trends at a low volume major trauma centre in Australia. ⋯ In this low volume major trauma centre, the implementation of a comprehensive quality improvement programme was associated with a reduction in crude and risk adjusted mortality and risk adjusted discharge to rehabilitation in severely injured patients.

For optimal treatment of trauma patients it is of great importance to identify patients who are at risk for severe injuries. The Dutch field triage protocol for trauma patients, the LPA (National Protocol of Ambulance Services), is designed to get the right patient, in the right time, to the right hospital. Purpose of this study was to determine diagnostic accuracy and compliance of this triage protocol. ⋯ The overall rate of undertriage (10.8%) was mainly influenced by a high rate of undertriage in the group of patients with only a positive mechanism criterion, therefore showing low diagnostic accuracy in selecting severely injured patients. As a consequence these patients with severe injury are undetected using the current triage protocol. As it has been shown that severely injured patients have better outcome in level one trauma care centres further optimisation of this protocol aiming at lowering undertriage is therefore essential, preferably without incrementing overtriage too much.

Effect of renal angioembolization on post-traumatic acute kidney injury after high-grade renal trauma: A comparative study of 52 consecutive cases.
Acute kidney injury (AKI) is associated with unfavourable outcomes and higher mortality after trauma. Renal angioembolization (RAE) has proved efficiency in the management of high-grade renal trauma (HGRT), but inevitably expose to unavoidable ischaemic areas or contrast medium nephrotoxicity which may impair renal function in the following hours. The aim of this study was to assess the potential acute impact of RAE on renal function in a consecutive series of HGRTs treated nonoperatively. ⋯ In a population of nonoperatively treated HGRT, the incidence of AKI decreased from almost 30% to 10% at 48h and 96h. RAE proceeding did not seem to affect significantly the occurrence and course of AKI or renal recovery. The decision to use RAE should probably not be restricted by fear of worsening renal function.
