Prior studies identified increased penetrating trauma rates during the earlier phase of the COVID-19 pandemic, but there is limited study of penetrating trauma rates in 2021 or at a national level. We evaluated trends in prehospital encounters for penetrating trauma in 2020 and 2021 using a national database.
We conducted a retrospective analysis of the National Emergency Medicinal Services (EMS) Information System (NEMSIS) combined 2018-2021 databases of prehospital encounters. We calculated penetrating trauma yearly and monthly rates with 95% confidence; both overall and for each census region. We compared trauma rates in 2020 and 2021 to combined 2018/2019.
There were 67,457 (rate of 0.30%) penetrating traumas in 2018, 86,054 (0.30%) in 2019, 95,750 (0.37%) in 2020, and 98,040 (0.34%) in 2021. Nationally, trauma rates were higher from March 2020 to July 2021 than baseline. Penetrating trauma rates from May-December 2021 were lower than May-December of 2020. All census regions similarly had increased trauma rates during from March 2020 to July 2021.
We identified elevated rates of trauma on 2020 that lasted until July of 2021 that was present in all US census regions.
先前的研究确定 COVID-19 大流行早期阶段穿透性创伤发生率增加，但对 2021 年或全国范围内穿透性创伤发生率的研究有限。我们使用国家数据库评估 2020 年和 2021 年创伤前接触穿透性创伤的趋势。
我们对国家紧急医疗服务 (EMS) 信息系统 (NEMSIS) 2018-2021 年的创伤前接触数据库进行了回顾性分析。我们计算了每年和每月的穿透性创伤发生率，置信区间为 95%；包括整体和每个普查区域。我们将 2020 年和 2021 年的创伤率与 2018/2019 年的综合数据进行了比较。
2018 年有 67457 例（发生率为 0.30%）穿透性创伤，2019 年有 86054 例（0.30%），2020 年有 95750 例（0.37%），2021 年有 98040 例（0.34%）。全国范围内，2020 年 3 月至 7 月创伤率高于基线。2021 年 5 月至 12 月穿透性创伤发生率低于 2020 年同期。所有普查区域在 2020 年 3 月至 7 月期间也同样经历了创伤率的上升。
我们确定了 2020 年创伤率升高，一直持续到 2021 年 7 月，并且在美国所有普查区域都存在。
