A multifaceted, home based, environmental intervention reduced asthma related morbidity in children with atopic asthma - air purifier for smoke

Method Design: a randomized controlled trial. Allocation:{concealed}. *oas_tag. loadAd("Middle1");
Blinding: Blind (
Result assessor).
Follow-up period: 1 year of intervention and 1 year of follow-up observation period.
Location: 7 major cities in the United States.
Patient: 5 ~ 937 children aged 11 (mean age 7. 7 y, 63% boys)
Patients with asthma and live in areas where income is lower than federal poverty levels.
Children are also required to receive one asthma-related inpatient treatment or two irregular asthma-related visits in the past 6 months, and received 1 of 11 skin tests for indoor allergens
Intervention: 1 year Zaii (nu200a=u200a469)
Or home assessment only (
Control group, n = 468).
Mimi is tailored to the level of sensitivity and environmental risk of each child.
Provide education and resources to the guardians of each child (
For example, anti-allergy mattresses, high efficiency vacuum cleaners and air purifiers)
Reduce exposure to allergens and tobacco smoke.
Profi is organized in 6 modules with a focus on reducing exposure to dust worms, passive smoking, cockroaches, pets, rodents and mold.
All families are assessed on home visits (
Including measurement of allergen concentration)
Throughout the study, it was performed at baseline and at intervals of 6 months.
Results: maximum number of days with symptoms (
Defined as the maximum of 3 variables: the number of days of breathing, chest tightness, or cough;
Number of nights where sleep is interrupted due to asthma;
And the number of days a child has to slow down or stop playing due to asthma)
2 weeks before the telephone interview (
The whole study is done every 2 months).
Patient follow-up: 93% in 1 year and 88% in 2 years (
Intention to treat analysis).
