We conducted a review of the literature pertaining to the use of risk communication strategies for vulnerable populations in any stages of emergency preparedness, response, or recovery. Our review included peer-reviewed citations published in English since January 1, 2000. Using these limits, the search strategy in Table A1 was used to identify citations for possible review in four databases (PubMed, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Social Science Citation Index). Additionally, all references dated 2000 or later in the National Cancer Institutes Risk Communication Bibliography were searched, and publications posted on the Center for Risk Communication website (http://www.centerforriskcommunication.com/home.htm) were also reviewed for inclusion. The review research team (EB and SS) examined titles and abstracts to filter out duplicate retrievals and to determine whether citations met additional inclusion criteria (Criterion A, Table A1).
|TABLE A1. Literature Review Search Strategy and Inclusion Criteria|
|Search Strategy||[risk communication OR health communication OR public health messaging] AND [emergency preparedness OR emergency OR preparedness OR emergency response OR emergency recovery OR public health emergency OR disaster OR disaster preparedness OR disaster response OR disaster recovery]||
1268 citations identified by search strategy
From over 1200 citations identified by our search strategy, 203 met Criterion A. These citations represented the broad literature on risk communication and public health emergencies. To identify which of these specifically addressed vulnerable populations (Criterion B), the review team conducted a second, more thorough abstract review of these 203 citations. Forty (20 percent) were determined to substantively address public health emergency risk communication for vulnerable populations and represented the final literature sample for full review.
