Study design details

• Main study objective:
  The overall objective of the project is to compare the rate of severe asthma exacerbation in children and adults treated by LABAs without ICs and with concomitant ICs with the rate amongst those treated by ICs without LABAs under the conditions of routine clinical care, after adjusting for baseline differences in severity.
• Outcomes:
  Severe Asthma exacerbation. In the Astro-lab study, the definition of severe asthma exacerbation will be the combination of patient-reported courses of oral corticosteroids for asthma, asthma-related urgent medical visits, asthma-related hospital contacts or death. Adherence, Asthma control and quality of life.
• Data analysis plan:
  Descriptive statistics will be provided for each exposure group. In addition different types of analysis are planned : - analysis based on the 4 initial exposure groups "intention to treat"- Cohort analysis with time-dependent variables analysis- Case -crossover study approach (if applicable)- Nested case control study (if applicable)
