On March 9th, 2020, the Italian government decided to go into lockdown due to the COVID-19 pandemic, which led to changes in the workflow of radiological examinations.
Aim of the study is to illustrate how the workload and outcome of radiological exams changed in a community hospital during the pandemic.
The exams performed in the radiology department from March 9th to March 29th, 2020 were retrospectively reviewed and compared to the exams conducted during the same time-period in 2019. Only exams coming from the emergency department (ED) were included. Two radiologists defined the cases as positive or negative findings, based on independent blind readings of the imaging studies. Categorical measurements are presented as frequency and percentages, and p-values are calculated using the Chi-squared test.
There was a significant reduction in the amount of exams performed in 2020: there were 143 (93|65% male, 60.7±21.5 years) patients who underwent radiological examinations from the ED vs. 485 (255|53% male, 51.2±24.8 years) in 2019. Furthermore, the total number of ED exams dropped from 699 (2019) to 215 (2020). However, the percentage of patients with a positive result was significantly higher in 2020 (69|48%) compared to 2019 (151|31%) (p<.001). The reduction of emergency radiological examinations might be a result of the movement restrictions enforced during the lockdown, and possible fear of the hospital as a contagious place. This translated to a relative increase of positive cases as only patients with very serious conditions were accessing the ED.
2020 年 3 月 9 日，意大利政府因 COVID-19 疫情决定封锁，这导致放射学检查的工作流程发生变化。
本研究旨在说明在疫情期间社区医院的放射学检查工作量和结果如何变化。
回顾性分析 2020 年 3 月 9 日至 3 月 29 日放射科进行的检查，并与 2019 年同期进行的检查进行比较。仅纳入来自急诊部（ED）的检查。两位放射科医生根据影像学研究的独立盲读结果将病例定义为阳性或阴性发现。分类测量以频率和百分比表示，使用卡方检验计算 p 值。
2020 年放射学检查量显著减少：ED 共进行 143 例（93|65%男性，60.7±21.5 岁）放射学检查，而 2019 年则为 485 例（255|53%男性，51.2±24.8 岁）。此外，ED 检查总数从 699 例（2019 年）降至 215 例（2020 年）。然而，2020 年阳性结果患者的比例明显高于 2019 年（69|48%）（p<.001）。紧急放射学检查减少可能是封锁期间实施的出行限制以及对医院作为传染病场所的可能恐惧所致。这导致阳性病例的相对增加，因为只有病情非常严重的患者才能进入 ED。
