Effect of shelter-in-place on emergency department radiology volumes during the COVID-19 pandemic.

ABSTRACT: PURPOSE:The coronavirus disease 2019 (COVID-19) pandemic has led to significant disruptions in the healthcare system including surges of infected patients exceeding local capacity, closures of primary care offices, and delays of non-emergent medical care. Government-initiated measures to decrease healthcare utilization (i.e., "flattening the curve") have included shelter-in-place mandates and social distancing, which have taken effect across most of the USA. We evaluate the immediate impact of the Public Health Messaging and shelter-in-place mandates on Emergency Department (ED) demand for radiology services. METHODS:We analyzed ED radiology volumes from the five University of California health systems during a 2-week time period following the shelter-in-place mandate and compared those volumes with March 2019 and early April 2019 volumes. RESULTS:ED radiology volumes declined from the 2019 baseline by 32 to 40% (p < 0.001) across the five health systems with a total decrease in volumes across all 5 systems by 35% (p < 0.001). Stratifying by subspecialty, the smallest declines were seen in non-trauma thoracic imaging, which decreased 18% (p value < 0.001), while all other non-trauma studies decreased by 48% (p < 0.001). CONCLUSION:Total ED radiology demand may be a marker for public adherence to shelter-in-place mandates, though ED chest radiology demand may increase with an increase in COVID-19 cases.

Project description:IntroductionThe SARS-CoV-2 coronavirus pandemic may cause significant morbidity and mortality in adults, yet severe cases are rare among children. The indirect impact of the pandemic on health care delivery in general and pediatric emergency department (PED) visits in particular has been widely reported.AimsTo assess the impact of the pandemic and the social restrictions imposed in its wake on PED visits and hospitalization rates in our Israeli medical center. We also sought to track these data in relation to the variation in pandemic severity and social restrictions over time. A comparison of this data with that of the adult emergency department was also performed.MethodsData for this study were drawn from the Shaare Zedek Medical Center (SZMC), Jerusalem, Israel computerized databank. The daily number of PED and adult ER visits as well as hospitalizations resulting from these visits during the months January-July during the years 2018, 2019, 2020 were recorded. We compared the risk ratio for hospitalization in 2019 and 2020, as well as the incidence rate ratio.ResultsDuring March and April there was a decrease in PED visits from 4,588 visits in 2019 to 2,527 visits in 2020 (ratio = .551, 95%CI [.52,.58]. Despite the drop in PED visits, the rate of hospitalizations rose with respect to 2019 (Risk Ratio = 1.31, p < .001, 95%CI [1.17,1.47]). Similar but more moderate trends were seen in the adult ED. From May-July 2020, after the lockdown was lifted, PED visits remained 30% below the same time period from 2018 and 2019, while the hospitalization rate returned to its pre-pandemic level.ConclusionsA significant drop in PED visits is seen to extend well beyond the peak of the pandemic and the lockdown period. This highlights the potential risk of children with serious emergencies becoming casualties of the pandemic by their not being brought to medical attention. Efforts should be made to raise public awareness among parents and other caretakers of children regarding this matter.
