理论基础和目标：预测模型和轶事文章表明，在新冠肺炎大流行期间，放射科实践失去了正常成像体积的50%-70%。使用实际机构数据，我们调查了此次公共健康危机期间影像使用和收入的变化。材料和方法：将2020年3月8日至4月30日8周内进行的影像归类为新冠肺炎医疗危机时间框架。这个日期范围的第一周和之前的10周被用来得出正常的实践预期数量。使用滚动的7天总值进行成交量跟踪和比较。根据患者环境(门诊、住院、急诊)和成像方式(X射线、CT、乳房X光摄影、核磁共振、核医学/PET、美国)得出并组织总的成像利用率。对流量最大的三家医院进行了分析。收入信息从医院计费系统收集。结果：2020年4月7日至13日，全系统影像量减少了55%。与正常做法相比，门诊检查减少了68%。紧急检查减少了48%，住院检查减少了31%。乳房X光检查和核医学扫描是受影响最大的方式，分别减少了93%和61%。与其他规模较小的门诊医院相比，主校区医院的相对成像容量损失较小。在最低点，来自主校园成像服务的技术部分收入与正常实践相比显示出49%的负差异。结论：提供的实际成像使用数据的趋势和大小将有助于为基于证据的决策提供信息，以便更准确地预测数量、政策变化以及为当前和未来的流行病做好机构准备。
Rationale and Objectives: Predictive models and anecdotal articles suggest radiology practices were losing 50%-70% of their normal imaging volume during the COVID-19 pandemic. Using actual institutional data, we investigated the change in imaging utilization and revenue during this public health crisis.Materials and Methods: Imaging performed within the 8-week span between March 8 and April 30, 2020 was categorized into the COVID-19 healthcare crisis timeframe. The first week of this date range and the 10 weeks prior were used to derive the normal practice expected volume. A rolling 7-day total value was used for volume tracking and comparison. Total imaging utilization was derived and organized by patient setting (outpatient, inpatient, emergency) and imaging modality (X-ray, CT, Mammography, MRI, Nuclear Medicine/PET, US). The three highest volume hospitals were analyzed. Revenue information was collected from the hospital billing system.Results: System-wide imaging volume decreased by 55% between April 7 and 13, 2020. Outpatient exams decreased by 68% relative to normal practice. Emergency exams decreased by 48% and inpatient exams declined by 31%. Mammograms and nuclear medicine scans were the most affected modalities, decreasing by 93% and 61%, respectively. The main campus hospital experienced less relative imaging volume loss compared to the other smaller and outpatient-driven hospitals. At its lowest point, the technical component revenue from main campus imaging services demonstrated a 49% negative variance from normal practice.Conclusion: The trends and magnitude of the actual imaging utilization data presented will help inform evidence-based decisions for more accurate volume predictions, policy changes, and institutional preparedness for current and future pandemics.
