Primary outcomePrimary: Asthma Control Questionnaire (ACQ) — 1.2; 1.4; 0.8; 1.4 score on a scale
Summary
Older asthmatics have considerably worse outcomes than younger patients with asthma. In this study, the investigators will evaluate the role of symptom perception as a key determinant of poorer outcomes and lower adherence to asthma self-management behaviors among older asthmatics. The proposed study is significant for its potential to greatly advance understanding of the mechanisms related to worse outcomes in older adults, and it will provide actionable data for new interventions to improve self-management.
