Asthma and allergic rhinitis are chronic diseases whose control is multifactorial (drug treatment, therapeutic education of the family and the child, consideration of a possible allergen...). When this control is not optimal, it leads to significant school absenteeism, pediatric emergency room visits and hospitalizations. Environmental conditions at home play a role in asthma exacerbations and poor control of allergic rhinitis in children. Mites, animal allergens, passive smoking, molds, cockroaches, household products, etc., are the main causes. The visit of a home environment advisor, who intervenes on medical prescription, makes it possible to evaluate the source of allergens and pollutants in the home and then to propose changes to the home. This position was created in France in 2009 by the Ministry of the Environment and is funded by the Agence Régional de Santé (ARS - Regional Health Agency). The few studies carried out to assess the effectiveness of a home visit by an environmental advisor on exacerbations of these diseases are contradictory: some show an improvement in the quality of life of asthmatic children after a home visit (via the average reduction in the number of days with symptoms/year) as well as a reduction in asthma-related morbidity thanks to a reduction in exposure to indoor allergens. Others have shown that it does not reduce the number of emergency room visits for asthma exacerbations. Furthermore, it would appear that targeted allergen avoidance measures do not reduce drug treatment in asthmatics who are already on optimal pharmacological treatment.
To our knowledge, there are no studies in France that use standardized medical questionnaires to assess disease control and quality of life before and after the visit of a home environmental consultant. For example, in Angers and Nantes, evaluation questionnaires are carried out with patients at 6 months and 1 year after a home visit, but the answers are not standardized and sometimes very subjective.
