To evaluate Interventional Radiology (IR) procedural volume changes at a large Midwest health system between March 17, 2020 and April 30, 2020 following a state-mandated shutdown of nonessential procedures during the initial phase of COVID-19.
IR procedural volumes were compiled, stratified by location and compared with Diagnostic Radiology (DR) volumes during the same timeframe. Procedure volume was categorized by type, including oncology, dialysis interventions, and drainage procedures with comparisons made using Z-score test for proportions. IR and system-wide surgical procedural volume was compared with baseline values.
System-wide IR procedural volume decreased by 35%, with a 41% decrease in outpatient and a 25% decrease in inpatient volume during the state-mandated order. DR volume decreased by 45%, with a 57% decrease in outpatient and a 22% decrease in inpatient volume. Total IR procedural volume during the mandate was 1077 versus 1518 during the preceding six weeks. The proportion of Interventional Oncology and dialysis interventions showed no significant change (p > 0.05) while that of drainage procedures increased (p < 0.05). Compared to baseline values, system-wide procedural volumes for IR, Vascular Surgery, Urology, General Surgery, Gastroenterology and Gynecology decreased by 3%, 11%, 25%, 20%, 38% and 31% in March 2020 and 25%, 47%, 68%, 63%, 79% and 73% in April 2020 respectively.
Outpatient IR volumes were less impacted compared to DR during the initial phase of COVID-19. Oncology, dialysis and drainage interventions may be considered essential procedures due to their stability. IR volumes were less affected compared to other procedural specialties.
在 COVID-19 初始阶段，由于州政府强制关停非必要手术，评估一家中西部大型医疗系统 2020 年 3 月 17 日至 4 月 30 日期间介入放射学（IR）手术量的变化。
汇总 IR 手术量，按位置分层，并与同期诊断放射学（DR）手术量进行比较。根据类型对手术量进行分类，包括肿瘤学、透析干预和引流程序，并使用 Z 分数检验进行比较。比较了 IR 和全系统手术手术量与基线值的差异。
全系统 IR 手术量下降 35%，门诊手术量下降 41%，住院手术量下降 25%。DR 手术量下降 45%，门诊手术量下降 57%，住院手术量下降 22%。在强制命令期间，IR 总手术量为 1077 次，而前六周为 1518 次。介入肿瘤学和透析干预的比例没有显著变化（p>0.05），而引流程序的比例增加（p<0.05）。与基线值相比，2020 年 3 月全系统 IR、血管外科、泌尿外科、普通外科、胃肠病学和妇科手术量分别下降 3%、11%、25%、20%、38%和 31%，2020 年 4 月分别下降 25%、47%、68%、63%、79%和 73%。
在 COVID-19 初始阶段，与 DR 相比，门诊 IR 手术量受影响较小。由于其稳定性，肿瘤学、透析和引流干预可能被视为必要程序。与其他手术专业相比，IR 手术量受影响较小。
