Official title

Comparative Effectiveness of Environmental Intervention and Standard Care in Ability to Reduce Pharmacologic Therapy for Asthma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Exposure to household allergens is a major contributor to asthma symptoms. Aggressive measures to reduce household allergens has the potential to reduce asthma symptoms and the need for medications to control asthma. The investigators plan to enroll patients aged 6 and above into a single blind, randomized study comparing intensive environmental intervention with usual asthma care over a 48 week study period. All subjects will have asthma treatment optimized according to guideline based care. Subjects will be randomized to an aggressive environmental remediation arm versus distribution of written materials regarding allergen reduction ("usual care"). Primary outcome measure will be ability to reduce asthma step therapy. Secondary outcomes include measures of lung function, asthma biomarkers and quality of life.
