Brief Summary
The purpose of this study is to assess the evolution of disease control, health-related quality of life, and the risk of severe asthma exacerbations in children and adolescents with persistent asthma in Spain at short, mid and long-term follow-up. Patient-reported information in this project is collected by computer assisted telephone interviews (CATI) and a mobile application (ARCA App).

Outcome Measures
Primary Outcomes (3)
Change from baseline in symptoms control, measured with the Asthma Control Questionnaire (ACQ)
Symptoms control is measured with the Asthma Control Questionnaire (ACQ-symptoms) only, which assesses the frequency of 5 asthma symptoms (night-time waking, symptoms on waking, activity limitation, shortness of breath, and wheeze) during the previous week on a 7-point Likert scale from 0 (no impairment) to 6 (maximum impairment). The overall score, calculated as the mean of item responses, ranges from 0 to 6. A score \>1.5 is considered not well-controlled asthma, and scores \<0.75 well-controlled asthma.
2, 5, 7 and 10 years after inclusion
Change from baseline in Health-Related Quality of Life, measured with the EuroQol
The EQ-5D consists of 5 dimensions ("mobility", "looking after myself", "doing usual activities", "having pain/discomfort" and "feeling worried/sad/unhappy). It includes also a visual analogue scale (EQ-VAS) on the general health status from 0 (worst health status) to 100 (best health status possible). The EQ-5D index ranges from 1 (best health state) to negative values (health states valued as worse than death), where 0 is equal to death, allowing the calculation of Quality-Adjusted Life-Years (QALYs).

Number of severe asthmatic exacerbations
As a screening to detect asthma exacerbation, the experience of asthma worsening question is administered through the ARCA app: "In the last month, have you had to take any pill, syrup, oral solution or go to the doctor or hospital, due to asthma worsening?" (Yes/No). If the answer is "yes", a phone call confirms or discards a severe asthma exacerbation through the following questions: "Did you visit or phone your general practitioner, out-of-hours, or walk-in center because your asthma got worse?", "Did you call an ambulance or go to the hospital because of your asthma?", "Did you take steroids tablets (such as Prednisolone or Deltacortril) for at least 2 days because of your asthma?" If the participant answers "yes" to at least one of the 3 questions, an asthma exacerbation is confirmed. These questions were constructed applying the definition of the American Thoracic Society and the European Respiratory Society.
5 and 10 years after inclusion
Secondary Outcomes (3)
Change from baseline in adherence to the treatment, measured with the Medication Intake Survey adherence scale-Asthma (MIS-A)
2, 5, 7 and 10 years after inclusion
Change from baseline in quality of the inhaler technique, measured with the Inhalation Technique Scale

Study Arms (1)
Asthma Research in Children and Adolescents - Spanish Cohort
Groups defined according to treatments prescribed during regular clinical practice and to the exposure to inhalation techniques monitoring
Interventions
Any corticosteroid (beclomethasone, budesonide, ciclesonide, fluticasone propionate, fluticasone furoate, mometasone, and triamcinolone) prescribed by the pediatrician as an inhaled controller medication, for daily management of asthma. The daily dose of ICs prescribed will be translated into beclomethasone equivalent.
Beclomethasone/formoterol, budesonide/formoterol, fluticasone furoate/vilanterol, fluticasone propionate/formoterol, fluticasone propionate/salmeterol, and mometasone/formoterol. Any of these combinations prescribed by the pediatrician as an inhaled controller medication, for daily management of asthma.
Low-dose oral corticosteroids, long-acting muscarinic antagonist (tiotropium), low-dose macrolides (azithromycin), leukotrienes receptor antagonists (i.e. montelukast), or biologic agents (i.e. omalizumab).
Pressurized metered-dose inhalers (pMDIs), Breath-actuated pMDIs, Dry powder inhalers (DPIs), Nebulizers, Soft Mist Inhalers.
App users are randomized within each pediatrician into two groups of equal size defined within the subsample recruited, so that 50% of the participants are allocated to answer the inhalation techniques, and the other 50% are allocated to answer the environment support scales. Once the app is downloaded, at month 2 and every 6 months thereafter the intervention group answers the inhalation techniques scale (group 1) and the control group answers the environment support scale (group 2).
