Update: COVID-19 pandemic–associated changes in emergency department visits—United States, December 2020–January 2021.
Open accessAbstract
During March 29-April 25, 2020, emergency department (ED) visits in the United States declined by 42% after the declaration of a national emergency for COVID-19 on March 13, 2020. Among children aged ≤10 years, ED visits declined by 72% compared with prepandemic levels (1). To assess the continued impact of the COVID-19 pandemic on EDs, CDC examined trends in visits since December 30, 2018, and compared the numbers and types of ED visits by patient demographic and geographic factors during a COVID-19 pandemic period (December 20, 2020-January 16, 2021) with a prepandemic period 1 year earlier (December 15, 2019-January 11, 2020). After an initial decline during March-April 2020 (1), ED visits increased through July 2020, but at levels below those during the previous year, until December 2020-January 2021 when visits again fell to 25% of prepandemic levels. During this time, among patients aged 0-4, 5-11, 12-17, and ≥18 years, ED visits were lower by 66%, 63%, 38%, and 17%, respectively, compared with ED visits for each age group during the same period before the pandemic. Differences were also observed by region and reasons for ED visits during December 2020-January 2021; more visits during this period were for infectious diseases or mental and behavioral health-related concerns and fewer visits were for gastrointestinal and upper-respiratory-related illnesses compared with ED visits during December 2019-January 2020. Although the numbers of ED visits associated with socioeconomic factors and mental or behavioral health conditions are low, the increased visits by both adults and children for these concerns suggest that health care providers should maintain heightened vigilance in screening for factors that might warrant further treatment, guidance, or intervention during the COVID-19 pandemic.

The current trends in the number and proportion of mental health condition-related emergency department visits, along with previous research, indicate that the mental health effects of the pandemic might be particularly high among adolescent girls.
“The current trends in the number and proportion of MHC-related ED visits, along with previous research ( 1 , 2 , 4 -8 ), indicate that the mental health effects of the pandemic might be particularly high among adolescent girls.”
From Pediatric Emergency Department Visits Associated with Mental Health Conditions Before and During the COVID-19 Pandemic — United States, January 2019–January 2022 (2022) · cites this paper as [8]
The Results report a higher proportion of pediatric ED visits for mental and behavioral health concerns during December 2020–January 2021, and the Discussion says adults and children were seeking emergency care for such concerns. The paper does not establish that these trends were particularly high among adolescent girls; the reported mental-health comparisons are for children as a group, not by both age and sex. (LLM, conf=0.86)
Experimental — accuracy not yet measuredDeclines in mental health condition-related emergency department visits during 2020 align with previous research and with reported declines in overall volume of pediatric emergency department visits during the pandemic.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
