Pediatric Asthma Impairment and Risk Questionnaire: Rationale and development of a composite control tool

Asthma in children is a leading cause of missed school days, emergency department visits, and hospitalizations. Approximately 40% of children with asthma experience uncontrolled disease and annual exacerbations. There is a need for a validated composite tool for children, such as the Asthma Impairment and Risk Questionnaire (AIRQ), which was developed to assess current control and predict exacerbations in adolescents and adults with asthma.

To obtain feedback from children with asthma and their parents/caregivers to inform development of a version of the AIRQ for pediatric use (Peds-AIRQ).

Children with asthma aged 5 to 11 years and their parents/caregivers participated in cognitive interviews to elicit language describing asthma symptoms and exacerbations and to assess understanding and relevance of draft Peds-AIRQ questions. Physicians and parents/caregivers provided clinical information and performed assessments relative to the children's asthma morbidity.

There were 60 dyads that participated: children's mean (SD) age = 7.9 (1.9) years; 68% male, 45% non-White, 32% Hispanic, and 40% with public health insurance. Overall, 53% had well-controlled, 30% partly controlled, and 17% uncontrolled asthma, based on the Global Initiative for Asthma symptom control questions. Oral or injected corticosteroids were used for asthma by 53% of the children in the previous year. Participants found draft Peds-AIRQ items understandable and relevant. Seven impairment and 3 risk questions were retained for validation, along with 5 additional items containing wording or control threshold variations.

This study supports the need for developing a composite (impairment and risk) control tool to assess children aged 5 to 11 years with asthma and identified suitable questions for the validation of a Peds-AIRQ.
