Comorbidities in Difficult-To-Treat asthma (2021)

A Cross-sectional survey of 6048 adult Australians with current asthma in the community (conducted in Feb-March 2021 during Covid measures) found that:
– 21.7% had difficult-to-treat asthma (DTTA)
– 85.4% of the participants with DTTA had at least 1 other chronic condition (comorbidity)

Note: DTTA was defined as severe asthma and/or poor asthma control and/or urgent asthma healthcare in previous 12 months despite medium-high dose ICS/LABA.
