Uncontrolled Asthma among Adults, 2016

More than 60% of adults with current asthma had uncontrolled asthma

Controlled asthma has a minimal impact on everyday living. Uncontrolled asthma with frequent and intense episodes of symptoms can have a significant cost to families and society because it may relate to an increased risk of an emergency department visit, hospitalization, and work and school absenteeism. Asthma control was classified as well-controlled or uncontrolled based on the national asthma guidelines.*
