Selected Randomized Controlled Trials Documenting Benefit of Home Interventions in Asthma

Study	Population	Intervention	Outcomes
Morgan et al,87 2004	Children with poorly controlled asthma and documented sensitivity to home allergens	Visual inspection and dust collection All participants receive allergen-impermeable bed covers and HEPA filtration vacuums Child-specific interventions included HEPA air filters and pest control measures	Intervention reduced symptoms at 1- and 2-y follow-up time points
Evans et al,85 1999	Children with moderate or severe asthma	Allergen-impermeable bed covers and education about minimizing exposure to tobacco smoke, pets, and pests Social worker-administered global asthma intervention based on the Asthma Risk Assessment Tool	Intervention reduced symptom days and hospitalizations over a 2-y follow-up period
Kercsmar et al,86 2006	Children with symptomatic asthma living in a home with visible mold	Control group education about home cleaning and asthma management Intervention group also received home repairs aimed at remediation of water infiltration and mold (eg, HVAC maintenance)	Intervention reduced symptom days and exacerbations over 12 mo of follow-up

HEPA = high-efficiency particulate air; HVAC = heating, ventilation, and air conditioning.
