OBJECTIVES To describe the epidemiology of pediatric injury-related visits to children's hospital emergency departments (EDs) in the United States during early and later periods of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. METHODS We conducted a cross-sectional study using the Pediatric Health Information System, an administrative database to identify injury-related ED visits at 41 United States children's hospitals during the SARS-CoV-2 pandemic period (March 15, 2020 to March 14, 2021) and a 3 year comparator period (March 15-March 14, 2017-2020). For these 2 periods, we compared patient characteristics, injury type and severity, primary discharge diagnoses, and disposition, stratified by early (March 15, 2020 to June 30, 2020), middle (July 1, 2020 to October 31, 2020), and late (November 1, 2020 to March 14, 2021) pandemic periods. RESULTS Overall, ED injury-related visits decreased by 26.6% during the first year of the SARS-CoV-2 pandemic, with the largest decline observed in minor injuries. ED injury-related visits resulting in serious-critical injuries increased across the pandemic (15.9% early, 4.9% middle, 20.6% late). Injury patterns with the sharpest relative declines included superficial injuries (41.7% early) and sprains/strains (62.4% early). Mechanisms of injury with the greatest relative increases included (1) firearms (22.9% early; 42.8% middle; 37% late), (2) pedal cyclists (60.4%; 24.9%; 32.2%), (3) other transportation (20.8%; 25.3%; 17.9%), and (4) suffocation/asphyxiation (21.4%; 20.2%; 28.4%) and injuries because of suicide intent (-16.2%, 19.9%, 21.8%). CONCLUSIONS Pediatric injury-related ED visits declined in general. However, there was a relative increase in injuries with the highest severity, which warrants further investigation.

COVID-19 第一年与伤害相关的儿科急诊科就诊。

目的 描述在严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 大流行的早期和后期期间，美国儿童医院急诊科 (ED) 的儿科损伤相关就诊的流行病学。方法 我们使用儿科健康信息系统进行了一项横断面研究，该系统是一个管理数据库，用于确定在 SARS-CoV-2 大流行期间（2020 年 3 月 15 日至 2021 年 3 月 14 日）在 41 家美国儿童医院中与伤害相关的急诊就诊) 和 3 年比较期（2017-2020 年 3 月 15 日至 3 月 14 日）。对于这两个时期，我们比较了患者特征、损伤类型和严重程度、初次出院诊断和处置，按早期（2020 年 3 月 15 日至 2020 年 6 月 30 日）、中期（2020 年 7 月 1 日至 2020 年 10 月 31 日）分层，迟到（11 月 1 日，2020 年至 2021 年 3 月 14 日）大流行期间。结果 总体而言，在 SARS-CoV-2 大流行的第一年，与 ED 损伤相关的就诊次数减少了 26.6%，其中轻伤的降幅最大。在整个大流行期间，导致重伤的 ED 损伤相关就诊有所增加（早期 15.9%，中期 4.9%，晚期 20.6%）。相对下降幅度最大的损伤模式包括浅表损伤（早期 41.7%）和扭伤/拉伤（早期 62.4%）。相对增加最大的伤害机制包括（1）枪支（22.9% 早期；42.8% 中期；37% 晚期），（2）脚踏车（60.4%；24.9%；32.2%），（3）其他交通工具（20.8 %; 25.3%; 17.9%)，和 (4) 窒息/窒息 (21.4%; 20.2%; 28.4%) 和因自杀意图造成的伤害 (-16.2%, 19.9%, 21.8%)。结论 与儿科损伤相关的 ED 就诊量总体下降。然而，严重程度最高的伤害相对增加，这需要进一步调查。
