Study ObjectiveIn the initial period of the coronavirus disease 2019 (COVID-19) pandemic, there has been a substantial decrease in the number of patients seeking care in the emergency department. A first step in estimating the impact of these changes is to characterize the patients, visits, and diagnoses for whom care is being delayed or deferred.MethodsWe conducted an observational study, examining demographics, visit characteristics, and diagnoses for all ED patient visits to an urban level 1 trauma center before and after a state emergency declaration and comparing them with a similar period in 2019. We estimated percent change on the basis of the ratios of before and after periods with respect to 2019 and the decline per week using Poisson regression. Finally, we evaluated whether each factor modified the change in overall ED visits.ResultsAfter the state declaration, there was a 49.3% decline in ED visits overall, 35.2% (95% confidence interval -38.4 to -31.9) as compared with 2019. Disproportionate declines were seen in visits by pediatric and older patients, women, and Medicare recipients, as well as for presentations of syncope, cerebrovascular accidents, urolithiasis, and abdominal and back pain. Significant proportional increases were seen in ED visits for upper respiratory infections, shortness of breath, and chest pain.ConclusionThere have been significant changes in patterns of care seeking during the COVID-19 pandemic. Declines in ED visits, especially for certain demographic groups and disease processes, should prompt efforts to understand these phenomena, encourage appropriate care seeking, and monitor for the morbidity and mortality that may result from delayed or deferred care.Copyright © 2020 American College of Emergency Physicians.
