Clinical Effectiveness and Economical Impact of Medical Indoor Environment Counselors Visiting Homes of Asthma Patients

Summary

Asthma is one of the most prevalent chronic respiratory diseases, with potential lifethreatening impacts. Indeed, asthma is still responsible for about a thousand deceases per year in France, and constitutes a public health problem in our country as in many countries in the world. The economic burden of asthma is also very high, in terms of health care, and indirect costs including lost work and lost school days.

A few international and French studies have shown a positive clinical impact of Medical Indoor Environment Counselors (MIECs) visiting homes of asthma patients, mainly pediatrics. It has been proposed that MIECs could contribute to reduce patient exposure to many allergens and irritants, among them, house dust mite allergens, formaldehyde or molds. Most of the studies that show a significant decrease of hospitalization or visit in an emergency ward for asthma are monocentric and study the eviction of 1 such identified risk factor. By contrast, meta-analysis underline that additional studies are needed to evaluate the effectiveness of these interventions in adults, in a multicentric and controlled manner, with both clinical, environmental and economical endpoints.
