Firearm injuries have the highest case-fatality rate among pediatric trauma related deaths. We sought to determine whether demographics, mechanism of injury, and outcomes were age specific.
We performed a 5 year retrospective analysis of patients 0-19 years old with firearm related injuries. Children were divided into two cohorts based on age. Mann-Whitney and Pearson's X were used to compare continuous and categorical variables, respectively. Significance was established at p < 0.05.
Compared to their younger counterparts, children >15 years old were more likely to be male (82% vs. 90%, p = 0.02), African-American (71% vs 89%, p < 0.0001), and injured due to assault (76.9% vs 44.6%, p < 0.0001). Mortality rates for children <14 was 1.4 times the national average (10.7% vs. 7.5%) while the rate for children >15 was 3.9 times the national average (12.4% vs. 3.2%).
Firearm injuries continue to be a prevalent public health concern greatly affecting African-American adolescent males. Prevention strategies and trauma related healthcare resource utilization should target this group in order to reduce the risk of injury and improve outcomes and case-fatality in our population.
在儿童创伤相关死亡中，火器伤的病死率最高。我们试图确定人口统计学特征、损伤机制和结局是否具有年龄特异性。
我们对0至19岁火器相关损伤患者进行了为期5年的回顾性分析。儿童根据年龄分为两个队列。分别使用曼-惠特尼检验和皮尔逊卡方检验来比较连续变量和分类变量。p < 0.05时具有统计学意义。
与年龄较小的儿童相比，15岁以上的儿童更可能为男性（82%对90%，p = 0.02）、非裔美国人（71%对89%，p < 0.0001），且因袭击受伤（76.9%对44.6%，p < 0.0001）。14岁以下儿童的死亡率是全国平均水平的1.4倍（10.7%对7.5%），而15岁以上儿童的死亡率是全国平均水平的3.9倍（12.4%对3.2%）。
火器伤仍然是一个普遍的公共卫生问题，对非裔美国青少年男性影响极大。预防策略和与创伤相关的医疗资源利用应以该群体为目标，以降低受伤风险，改善我们人群的结局和病死率。
