Asthma emergency department visit rates have remained relatively stable since 2007. ED visits include patients who went to the ED and were subsequently admitted to the hospital.

The highest asthma ED visit rates are seen among children under the age of 5 years. Among children, asthma ED visit rates are higher for boys than girls, while among adults, rates are higher for women than men. In 2014, the age-adjusted asthma ED visit rate was 38.7 for males and 41.1 for females per 10,000.

In Minnesota, asthma emergency department visits follow seasonal patterns. The greatest number of ED visits are seen in the fall months, and the fewest number of ED visits are seen in the summer. This pattern is seen in all age groups below age 65. People age 65 and over have the lowest average daily number of ED visits and show less seasonal variation in emergency department visits. It is difficult to distinguish asthma from COPD in people age 65+. A major contributor to the fall increase in asthma ED visits is thought to be increasing rates of respiratory infections among children going back to school. Other possible contributing factors include pollen and mold.
