Summary

Asthma is a chronic disease. Prevalence of asthma in 2014 among Spanish population was 5%, of which 10% were diagnosed with severe asthma. According to Spanish National Guideline for the Management of Asthma (GEMA) 4.1 criteria, asthma can be classified according to its severity (intermittent, mild persistent, moderate persistent or severe persistent) or level of asthma control (controlled, partly controlled or uncontrolled). This Guideline describes that only 1 in 10 subjects with severe asthma is well controlled, meaning that there is a 90% prevalence of non-controlled severe asthma. This prospective, non-interventional, observational, multicenter and case-control study aims to assess the prevalence of severe asthma in Spanish Hospitals. The study will describe the characteristics of severe versus non-severe asthmatic subjects, assess their eligibility to receive biological treatments approved for this disease, resource consumption and evaluate the most prevalent phenotypes of severe asthma in Spain. Enrolled subjects will be divided into two cohorts, based on asthma severity according to the Global Initiative for Asthma (GINA) and the International European Respiratory Society (ERS)/American Thoracic Society (ATS) Guidelines. Cohort A: subjects diagnosed of severe asthma and Cohort B: subjects with non-severe asthma. Approximately 320 severe asthmatic subjects and 160 non-severe asthmatic subjects will be enrolled in the study. A software of big data will be used to do a sub study for comparing the results obtained through this software tool against results obtained through Gold standard classical methods used in this prospective observational study (the descriptive assessment of severe asthma prevalence and the prospective evolution of subjects).

Conditions

• Asthma

Interventions

Type	Name	Description
OTHER	Questionnaire	Subjects will be given an Electronic Case Report Form (eCRF) with a series of questionnaire such as Asthma Control Test, Morisky-Green Questionnaire and St George's Respiratory Questionnaire.
OTHER	Software of Big Data	Software of big data is a powerful data treatment algorithm works closely with Spanish Data Protection Agency as an example on how to reuse clinical information without conflicting with necessary data privacy. The system will process a vast amount of information (big data), so that the impact of random errors will be minimized.
