Comparative Study Observational Study
Usefulness of the Shock Index as a secondary triage tool.
Secondary triage at a major incident allows for a more detailed assessment of the patient. In the UK, the Triage Sort (TSO) is the preferred method, combining GCS, systolic BP (SBP) and RR to categorise Priority 1 casualties. The Shock Index (SI) is calculated by dividing HR by SBP (HR/SBP). This study examines whether SI is better at predicting need for life-saving intervention (LSI) following trauma than TSO. ⋯ RCDM/Res/Audit/1036/12/0050.

Modern body armour clearly reduces injury incidence and severity, but evidence to actually objectively demonstrate this effect is scarce. Although the Joint Theatre Trauma Registry (JTTR) alone cannot relate injury pattern to body armour coverage, the addition of computerised Surface Wound Mapping (SWM) may enable this utility. ⋯ Computerised SWM has objectively demonstrated the ability of body armour worn on current operations in Afghanistan to reduce wound incidence and severity. We recognise this technique is limited in that it only records the surface wound location and may be specific to this conflict. However, gathering electronic SWM at the same time as recording injuries for the JTTR was simple, required little extra time and therefore we would recommend its collection during future conflicts.

Protecting the neck from explosively propelled fragments has traditionally been achieved through a collar attached to the ballistic vest. An Enhanced Protection Under Body Armour Combat Shirt (EP-UBACS) collar has been identified as an additional method of providing neck protection but limited evidence as to its potential medical effectiveness exists to justify its procurement. ⋯ This technique confirms that reinforcing the neck collar of an EP-UBACS would be expected to reduce injury severity from neck wounds. However, without knowledge of entry wound locations for injuries to other body areas as well as the use of AIS scores without clinical or pathological verification its further use in the future may be limited. The ability to overlay any armour design onto a standardised human was potentially the most useful part of this tool and we would recommend developing this technique using underlying anatomical structures and not just the skin surface.

Review Meta Analysis
Determining the wounding effects of ballistic projectiles to inform future injury models: a systematic review.
Penetrating wounds from explosively propelled fragments and bullets are the most common causes of combat injury experienced by UK service personnel on current operations. There is a requirement for injury models capable of simulating such a threat in order to optimise body armour design. ⋯ Injury models should use the PWT to delineate the area of damage to tissues from penetrating ballistic projectiles. The PWT, or its individual components, will require quantification in terms of the amount of damage produced by different projectiles penetrating these tissues. There is a lack of information qualifying the injurious effect of the temporary cavity, particularly in relation to that caused by explosive fragments, and future models should introduce modularity to potentially enable incorporation of these mechanisms at a later date were they found to be significant.
