Early-Stage Radiology Volume Effects and Considerations with the Coronavirus Disease 2019 (COVID-19) Pandemic: Adaptations, Risks, and Lessons Learned.

摘要: Abstract Objective The coronavirus disease 2019 (COVID-19) pandemic resulted in significant loss of radiologic volume as a result shelter-at-home mandates and delay non-time-sensitive imaging studies to preserve capacity for the pandemic. We analyze volume-related impact COVID-19 on six academic medical systems (AMSs), three high surge (high-surge) low (low-surge) regions, large national private practice coalition. sought assess adaptations, risks actions, lessons learned. Methods Percent change 2020 per week was compared with corresponding calculated each 14 modalities overall total, outpatient, emergency, inpatient high-surge AMSs low-surge Results Steep examination drops occurred during 11, slow recovery starting 17. lowest total AMS drop 40% same period previous year, largest 70%. greatest decreases were seen screening mammography dual-energy x-ray absorptiometry scans, smallest PET/CT, x-ray, interventional radiology. Inpatient least impacted outpatient or emergency imaging. Conclusion Large percentage from weeks 11 through 17, studies, larger than AMSs. which delays had greater perceived adverse consequences.
