摘要

背景:尽管急诊科在努力减少低价值成像,但 CT 成像的使用仍在不断增加,尤其是在 COVID-19 大流行期间和之后。本研究旨在调查 COVID-19 大流行相关措施对急诊科要求进行 CT 检查的趋势和数量的影响:方法:回顾性分析了 2014 年 1 月 1 日至 2023 年 12 月 12 日期间在我院三级医院进行的头部、胸部和/或腹部骨盆 CT 检查(n = 161 008)和胸部 X 光片检查(n = 113 240)。将 COVID-19 大流行期间(2020 年 3 月至 2022 年 3 月)和之后(2022 年 4 月至 2023 年 12 月)急诊科申请的 CT 检查(头部、胸部、腹部、双区域和多创伤)和胸部 X 光片与大流行前对照期(2018 年 2 月至 2020 年 2 月)进行了比较。分析包括每次急诊就诊的 CT 检查,以及基于大流行前趋势和住院患者数据的预测模型。正则表达式文本搜索算法确定了最常见的临床问题:结果:在大流行期间,双区域 CT 和胸部 CT 检查的使用率较高(分别为 + 116.4% 和 + 115.8%;P 结论:在 COVID-19 大流行之后,CT 检查的使用率有所下降:COVID-19 大流行后,急诊科胸部 CT 和双区域 CT 的使用率与大流行前相比出现了不成比例的持续激增。

Trends in CT examination utilization in the emergency department during and after the COVID-19 pandemic.

Background: The increasing use of CT imaging in emergency departments, despite efforts of reducing low-value imaging, is not fully understood, especially during and after the COVID-19 pandemic. The aim of this study was to investigate the impact of COVID-19 pandemic related measures on trends and volume in CT examinations requested in the emergency department.

Methods: CT examinations of the head, chest, and/or abdomen-pelvis (n = 161,008), and chest radiographs (n = 113,240) performed at our tertiary care hospital between 01/2014 and 12/2023 were retrospectively analyzed. CT examinations (head, chest, abdomen, dual-region and polytrauma) and chest radiographs requested by the emergency department during (03/2020-03/2022) and after the COVID-19 pandemic (04/2022-12/2023) were compared to a pre-pandemic control period (02/2018-02/2020). Analyses included CT examinations per emergency department visit, and prediction models based on pre-pandemic trends and inpatient data. A regular expressions text search algorithm determined the most common clinical questions.

Results: The usage of dual-region and chest CT examinations were higher during (+ 116,4% and + 115.8%, respectively; p < .001) and after the COVID-19 pandemic (+ 88,4% and + 70.7%, respectively; p < .001), compared to the control period. Chest radiograph usage decreased (-54.1% and - 36.4%, respectively; p < .001). The post-pandemic overall CT examination rate per emergency department visit increased by 4.7%. The prediction model underestimated (p < .001) the growth (dual-region CT: 22.3%, chest CT: 26.7%, chest radiographs: -30.4%), and the rise (p < .001) was higher compared to inpatient data (dual-region CT: 54.8%, chest CT: 52.0%, CR: -32.3%). Post-pandemic, the number of clinical questions to rule out "pulmonary infiltrates", "abdominal pain" and "infection focus" increased up to 235.7% compared to the control period.

Conclusions: Following the COVID-19 pandemic, chest CT and dual-region CT usage in the emergency department experienced a disproportionate and sustained surge compared to pre-pandemic growth.
