Impact of Asthma (initial check)

Thank you for your interest in the Impact of Asthma study!
During the study, we noticed that most people could not join the study due to one reason: we need patients with asthma who have had at least one case of symptoms worsening that required extra treatment with prednisone a hospital admission or an emergency room attendance.
Unfortunately, people who have not needed one or more courses of prednisone or a visit to the hospital or emergency room in the last year cannot participate in the Impact of Asthma study.
If you have had one or more courses of prednisone or a visit to the hospital or emergency room in the last year, you can sign up to the study with the button below.
Thanks!
