| Cross-sectional phase | Longitudinal phase |
---|---|---|
Primary objectives | • Prevalence of patients with controlled or uncontrolled/partly controlled asthma | • Proportions of patients with controlled, partly controlled and uncontrolled asthma after 12 months from the cross-sectional phase visit |
• Health-related quality of life | • Proportion of patients with uncontrolled/partly controlled asthma switching to controlled asthma after 12 months from the cross-sectional phase visit | |
• Factors associated with asthma control | • Changes in quality of life after 12 months | |
• Factors associated with the gain of asthma control | ||
Secondary objectives | • Proportion of asthmatic smokers and their level of asthma control | • Association between (current) level of asthma control and (future) risk of exacerbations |
• Antiasthmatic therapies | • Relation between change in asthma control and change in rate of exacerbations during the longitudinal phase (including stratified analyses according to GINA treatment level) | |
• Medication adherence | • Antiasthmatic therapies | |
• Healthcare costs over 3 months before the cross-sectional phase visit | • Proportion of patients with uncontrolled/partly controlled asthma that reach control after 3 and 6 months from cross-sectional phase visit | |
• Rate of severe exacerbations in the last 12 months before the cross-sectional phase visit | • Medication adherence | |
• Reasons for poor control according to the Investigators’ and the patients’ opinion | • Healthcare costs | |
• Lung function parameters, if available | • Rate of severe exacerbations and the time to first severe exacerbation | |
• Reasons for poor control according to the Investigators’ and the patients’ opinion | ||
