Weapons injuries during and after periods of conflict: retrospective analysis.

Abstract

To assess the relative frequency of weapon injuries during conflict and after periods of conflict in the absence of disarmament. Retrospective analysis of a database of war wounds. Region with a protracted conflict between rival combatant groups and a subsequent transition to the uncontested military authority of a single power. 2332 people who received weapons injuries during the conflict or post-conflict periods and were admitted to hospital within 24 hours of injury. Percentage change in mean monthly admission rate by weapon type between conflict and post-conflict periods; annual incidence of injury by weapon type during conflict and post-conflict periods; percentage change in annual incidence by weapon type between conflict and post-conflict periods. Mean monthly admission rates for injuries from fragmentation munitions decreased by 8% between conflict and post-conflict periods and by 23% for injuries from mines and 32% for gunshot injuries. The decline in admissions for all injuries was 23%. After adjustment for population growth over the study period, declines in annual incidence were 22% for fragmentation munitions injuries, 34% for mine injuries, and 40% for gunshot injuries. The decline in incidence for all injuries was 33%. In-hospital mortality from weapons related injuries increased from 2.5% to 6.1% (P < 0.001) between conflict and post-conflict periods. In this setting, continued availability of weapons is associated with increased mortality and a level of injuries from weapons that is only somewhat reduced from that observed during a period of conflict.
