The World Health Organisation declared the coronavirus disease 2019 (COVID-19) a pandemic on March 11, 2020. While globally, the relative caseload has been high, Australia's has been relatively low. During the pandemic, radiology services have seen significant changes in workflow across modalities and a reduction in imaging volumes.
To investigate differences in modality imaging volumes during the COVID-19 pandemic across a large Victorian public health network.
A retrospective analysis from January 2019 to December 2020 compared imaging volumes across two periods corresponding to the pandemic's first and second waves. Weekly volumes across patient class, modality and mobile imaging were summed for periods: wave 1 (weeks 11 to 16 for 2019; weeks 63 to 68 for 2020) and wave 2 (weeks 28 to 43 for 2019; weeks 80 to 95 for 2020). Microsoft Power Business Intelligence linked to the radiology information system was used to mine all completed examinations.
Summed weekly data during the pandemic's first wave showed the greatest decrease of 29.8% in adult outpatient imaging volumes and 46.3% in paediatric emergency department imaging volumes. Adult nuclear medicine demonstrated the greatest decrease of 37.1% for the same period. Paediatric nuclear medicine showed the greatest decrease of 47.8%, with angiography increasing by 50%. The pandemic's second wave demonstrated the greatest decrease of 23.5% in adult outpatient imaging volumes, with an increase of 18.2% in inpatient imaging volumes. The greatest decrease was 28.5% in paediatric emergency department imaging volumes. Nuclear medicine showed the greatest decrease of 37.1% for the same period. Paediatric nuclear medicine showed the greatest decrease of 36.7%. Mobile imaging utilisation increased between 57.8% and 135.1% during the first and second waves. A strong correlation was observed between mobile and non-mobile imaging in the emergency setting (Spearman's correlation coefficient = -0.743, 0.000). No correlation was observed in the inpatient setting (Spearman's correlation coefficient = -0.059, 0.554).
Nuclear medicine was most impacted, while computed tomography and angiography were the least affected by the pandemic. The impact was less during the pandemic's second wave. Mobile imaging shows continuous growth during both waves.
2020年3月11日，世界卫生组织宣布2019冠状病毒病（COVID-19）为大流行病。在全球范围内，病例相对数量一直很高，而澳大利亚的相对数量较低。在大流行期间，放射科服务在各个检查方式的工作流程方面发生了重大变化，成像量有所减少。
调查在COVID-19大流行期间，维多利亚州一个大型公共卫生网络中不同检查方式的成像量差异。
对2019年1月至2020年12月进行回顾性分析，比较了与大流行第一波和第二波相对应的两个时期的成像量。汇总了两个时期（第一波：2019年第11至16周；2020年第63至68周；第二波：2019年第28至43周；2020年第80至95周）按患者类别、检查方式和移动成像分类的每周成像量。使用与放射学信息系统相连的微软Power商业智能软件挖掘所有已完成的检查数据。
大流行第一波期间的每周汇总数据显示，成人门诊成像量降幅最大，为29.8%，儿科急诊科成像量降幅为46.3%。同期成人核医学成像量降幅最大，为37.1%。儿科核医学成像量降幅最大，为47.8%，而血管造影成像量增加了50%。大流行第二波期间，成人门诊成像量降幅最大，为23.5%，住院患者成像量增加了18.2%。儿科急诊科成像量降幅最大，为28.5%。同期核医学成像量降幅最大，为37.1%。儿科核医学成像量降幅最大，为36.7%。第一波和第二波期间，移动成像利用率增长了57.8%至135.1%。在急诊环境中，移动成像和非移动成像之间存在很强的相关性（斯皮尔曼相关系数=-0.743，P=0.000）。在住院患者环境中未观察到相关性（斯皮尔曼相关系数=-0.059，P=0.554）。
核医学受影响最大，而计算机断层扫描和血管造影受大流行影响最小。在大流行第二波期间影响较小。在两波期间，移动成像均持续增长。
