The following outlines the search strategy for home-based multi-trigger, multicomponent environmental interventions for adults and for children and adolescents.
With the assistance of a CDC librarian, the team searched for published studies in the following databases: MEDLINE, Cochrane Library, CINAHL, PsychINFO, Web of Science, EMBASE, ERIC, and Sociological Abstracts. The team also searched bibliographic reference lists and accepted suggestions of studies from members of the team.
The team considered studies for inclusion if they:
- Were primary research published in a journal or a technical or government report
- Were published in English
- Met minimum research quality criteria for study design and execution—specifically, using designs with before-and-after comparisons in the intervention group at least or comparisons across two groups receiving different levels of intervention
- Were community-based
- Evaluated one of nine identified asthma interventions
- Addressed secondary or tertiary prevention
Studies for home-based environmental interventions were considered if they also:
- Included at least one home visit
- Were multicomponent
- Were multi-trigger
- Evaluated one or more outcomes of interest
The team searched for and accepted for possible inclusion studies published from 1966 to February 2008.

The economic review team adjusted the search strategy used in the effectiveness review by adding keywords specifıc to economic evaluation, such as economic(s), cost, benefıt, cost–benefıt, benefıt–cost, utility, cost–utility, QALY, cost effectiveness, and effıciency. In addition to the databases searched in the effectiveness review (i.e., MEDLINE, EMBASE, ERIC, PsycINFO, Web of Science, Cochrane Library, Sociological Abstracts, and CINAHL), social science databases such as EconLit, Social Sciences Citations Index, and JSTOR; databases of the Centre for Reviews and Dissemination at the University of York; and Google were also used. These searches were conducted for 1950 through July 2008.
