INTRODUCTION
This report presents characteristics of emergency department (ED) visits by age group, sex, race and ethnicity, payment source, and mention of COVID-19, using data from the 2022 National Hospital Ambulatory Medical Care Survey (NHAMCS).
METHODS
Data for this report are from NHAMCS, an annual, nationally representative survey of nonfederal, general, and short-stay hospitals. Data analyses were performed using the statistical packages SAS version 9.4 and SAS-callable SUDAAN. Two-tailed tests with a significance level of < 0.05 were used to determine statistically significant differences between ED visit rates.
KEY FINDINGS
The overall ED visit rate was 47 visits per 100 people in 2022, and the ED visit rates were highest for infants younger than age 1 year (99 visits per 100 infants) and adults ages 75 and older (76 per 100 adults). The ED visit rate for Black or African American non-Hispanic people (91) was the highest among the selected racial and ethnic groups. In 2022, a COVID-19 diagnosis was confirmed for 4.8% of all ED patient visits.
