Emergency department visits during COVID-19 pandemic period compared to prior yearHow did the COVID-19 pandemic change who went to the emergency room?

This observational report describes an analysis of U.S. emergency department visits during the COVID-19 pandemic period from December 2020 to January 2021. The comparator was the same months from the year before the pandemic. The study aimed to assess changes in the number of emergency department visits.

The primary outcome was changes in the number of emergency department visits. However, the specific results, including the direction of change, effect size, absolute numbers, and statistical significance (p-value or confidence interval), were not reported in the provided information. No secondary outcomes were specified.

No information was provided regarding safety, adverse events, or tolerability of any intervention, as this was a descriptive analysis of visit patterns. Key limitations include the lack of reported results, which prevents assessment of the magnitude or significance of any observed changes. The funding sources and potential conflicts of interest were also not reported.

In terms of practice relevance, this report highlights an area of investigation but does not provide actionable quantitative data on how emergency department volumes changed during this specific pandemic period compared to the prior year. The absence of reported findings limits its direct clinical utility.
