The importance of health service planning for major incident management has been recognised since the World Trade Centre attacks of September 2001 and is highly relevant to planning for the 2012 Olympics. UK national Major Incident guidance stipulates the use of a system of triage for casualties to prioritise treatment and ensure "the greatest good for the greatest number". However, at least three triage systems are in use worldwide and no evidence exists to demonstrate their relative efficacy. The transport bombings in London on 7th July 2005 caused the largest number of casualties on mainland UK soil since World War 2. We aimed to validate three major incident triage systems using patient data from the 7th July bombings. ⋯ Systematic triage of mass casualties is effective but the amount of missing data seriously compromises any attempt to evaluate systems of trauma care in a major incident.

Comparative Study
Utility of interim ROTEM(®) values of clot strength, A5 and A10, in predicting final assessment of coagulation status in severely injured battle patients.
Proactive management of trauma-related coagulopathy requires early identification and rapid assessment in order to allow targeted resuscitation. This study determined whether early (interim) ROTEM(®) (TEM International GmbH, Munich, Germany) values could predict hypocoagulopathy in seriously injured military patients. ⋯ The A10 value of ROTEM(®) provides an early sensitive and specific assessment of coagulopathy after military trauma and may be of utility in guiding bespoke resuscitation. We found some speculative evidence that in major trauma platelet function is particularly affected.

Pneumothoraces are a common injury pattern in emergency medicine. Rapid and safe identification can reduce morbidity and mortality. A new handheld, battery powered device, the Pneumoscan (CE 561036, PneumoSonics Inc., Cleveland, OH, USA), using micropower impulse radar (MIR) technology, has recently been introduced in Europe for the rapid and reliable detection of PTX. However, this technology has not yet been tested in trauma patients. This is the first quality control evaluation to report on emergency room performance of a new device used in the trauma setting. ⋯ The Pneumoscan is an easy to use handheld technology with reliable results. In this series, the sensitivity to detect a PTX by the Pneumoscan was higher than by clinical examination and chest X-ray. Further studies with higher case numbers and a prospective study design are needed to confirm our findings.

Little is known about the costs of injury and their impact on injured persons and their families in Vietnam. This study aimed to examine the cost of injury in hospitalised patients and to identify the most costly injuries and those more likely to result in catastrophic household expenditure. ⋯ A high proportion of households experienced catastrophic expenditure following injury, highlighting the important need for programmes to prevent injuries, road traffic and fall-related injuries in particular. Furthermore, expansion of health insurance coverage may help individuals cope with the financial consequences of injury.

Early transfusion (ET=within 24h) has been shown to be required in approximately 5% of trauma patients. Critical care transfusion guidelines control transfusion triggers by evidence based cut-offs. Empirical guidelines influence decision making for ET in trauma. ⋯ The prospective evaluation of acutely transfused trauma patients showed a distinct pattern of transfusion triggers as the patient passes from ED to the OT and arrives to the ICU. The conventional transfusion trigger (haemoglobin level) is not appropriate in ET as early transfusion triggers are based on vital signs, blood gas results, injury patterns and anticipated major bleeding.
