Evaluating home-based, multicomponent, multi-trigger interventions: your results may vary.

In public health, we operate in a world of tight resources, making the best decisions possible to maximize benefıts to people with asthma, their families, nd our communities. The use of evidence-based interentions is an effective way to build on experience by mplementing interventions that have shown previous ffectiveness. The systematic review published in this upplement to the American Journal of Preventive Mediine was completed in order to identify effective asthma nterventions for reducing asthma morbidity in a comunity setting. The plan is to use the information to guide funded programs on how to best allocate their resources, as well as to direct our own research and evaluation efforts at the national level. Home-based asthma interventionswere chosen for the review in order to focus on efforts to reduce indoor asthma triggers because this type of intervention is used more and more at the state level, and there is not much information summarizing the effectiveness of these interventions on a community level. The two Guide to Community Preventive Services (Community Guide) reviews together are invaluable esources to help us make the right decisions for our rograms and, ultimately help people with asthma and heir families. TheseCommunity Guide reviews are excitng: They give us evidence that home-based environmenal interventions can improve the lives of children with sthma and their families. Moreover, moderate-intensity nterventions can be cost effective. The Air Pollution and Respiratory Health Branch at he CDC is committed to working with state asthma rograms to implement effective home-based environental interventions. As this new information is incororated into program planning, it is important to re-
