Asthma emergency department (ED) visits 2010–2018

Asthma emergency department (ED) visits rate* (per 10,000 population) by age group† and year: United States, 2010–2018.

The emergency department (ED) is an important place for patients to seek immediate care for asthma exacerbations. It may also be the main place of care for some patients who do not have a medical home or a primary care provider. The asthma ED visits rate with a primary diagnosis of asthma (per 10,000 population) for adults (trend slope p-value=0.42), for children (trend slope p-value=0.43), or for all ages (trend slope p-value=0.25) did not change significantly from 2010 through 2018 (Figure).
