Traumatic brain injury (TBI) is a life-altering condition that has affected many of our soldiers returning from war. In the current conflicts, the improvised explosive device (IED) has greatly increased the potential for soldiers to sustain a TBI. This study's objective was to establish benchmark admission rates for U.S. Army soldiers with TBIs identified during deployment to Iraq and Afghanistan.
The study population consisted of U.S. Army soldiers deployed to Iraq and Afghanistan from September 11, 2001, through September 30, 2007. Population data were merged with admission data to identify hospitalizations during deployment. Using the international Barell Injury Diagnosis Matrix, TBI-related admissions were categorized into Type 1 (the most severe), Type 2, and Type 3 (the least severe). All analyses were performed in 2008.
Of the 2898 identified TBI inpatient episodes of care, 46% were Type 1, 54% were Type 2, and less than 1% were Type 3. Over 65% of Type 1 injuries resulted from explosions, while almost half of all TBIs were non-battle-related. Overall TBI admission rates were 24.6 for Afghanistan and 41.8 for Iraq per 10,000 soldier-years. TBI hospitalization rates rose over time for both campaigns, although U.S. Army soldiers in Iraq experienced 1.7 times higher rates overall and 2.2 times higher Type 1 admission rates than soldiers in Afghanistan. The TBI-related proportion of all injury hospitalizations showed an ascending trend.
Future surveillance of TBI hospitalization rates is needed to evaluate the effectiveness of implementation of preventive measures.
创伤性脑损伤（TBI）是一种改变生活的疾病，许多从战争中归来的士兵都受到了影响。在当前的冲突中，简易爆炸装置（IED）大大增加了士兵遭受 TBI 的可能性。本研究的目的是确定 2001 年 9 月 11 日至 2007 年 9 月 30 日期间部署到伊拉克和阿富汗的美国陆军士兵 TBI 的入院基准率。
研究人群包括 2001 年 9 月 11 日至 2007 年 9 月 30 日期间部署到伊拉克和阿富汗的美国陆军士兵。将人口数据与入院数据合并，以确定部署期间的住院情况。使用国际 Barell 损伤诊断矩阵，将 TBI 相关入院病例分为 1 型（最严重）、2 型和 3 型（最不严重）。所有分析均于 2008 年进行。
在 2898 例确定的 TBI 住院病例中，46%为 1 型，54%为 2 型，不到 1%为 3 型。超过 65%的 1 型损伤是由爆炸引起的，而近一半的 TBI 与非战斗无关。阿富汗每 10000 名士兵年有 24.6 例 TBI 入院，伊拉克为 41.8 例。随着时间的推移，两项战役的 TBI 住院率都有所上升，尽管伊拉克的美国陆军士兵总体上的 TBI 住院率高出 1.7 倍，1 型入院率高出 2.2 倍。TBI 相关的所有伤害住院比例呈上升趋势。
需要对 TBI 住院率进行未来监测，以评估预防措施实施的效果。
