Abstract
The aim of this study was to characterise injury patterns and examine whether survival had improved over the last decade of conflict in Iraq and Afghanistan. A logistical regression model was applied to all UK casualty data from the Joint Theatre Trauma Registry.
There were 2785 casualties over the 10-years. 72% of casualties from hostile action were injured by blast weapons. The extremities were the post commonly injured body region, being involved in 43% of all injuries sustained. The New Injury Severity Score that was observed to be associated with a 50% chance of survival rose every year from 38 in 2003 to 62 in 2012. The odds ratio of surviving with a Trauma and Injury Severity Score (TRISS) of 50% rose by 1.349 (95% CI = 1.265–1.442) per year. The actual TRISS value associated with a 50% chance of survival dropped every year from 35.3% in 2003 to 0.9 in 2010 and was un-calculable in 2011–12.
This study confirms that the last decade of conflict has been characterised by blast wounds and injuries involving the extremities. A consistent improvement in survival over the 10 years has been demonstrated, to the point that traditional metrics for measuring improvement in trauma care have been exhausted.
