D isaster medicine and public health preparedness are commonly perceived as subfields of the larger fields of medicine and public health rather than being recognized as an emerging academic field embracing all of the disciplines that contribute to effective disaster response. As such, they serve as appropriate subjects for multidisciplinary work in the social sciences, whether it is a sociological analysis of mass behavior during a disaster, psychological studies of the willingness to work of various workforces, or organizational theory or network analyses applied to ad hoc disaster coalitions. Laboratory sciences and bioinformatics contribute as well to the development of new treatment modalities, medical products, and surveillance technologies. As is true in the broader medical and public health fields, much of the work is empirical and evaluative. In this article, the authors survey the literature in the field and suggest that broader, more ecologically based research is needed.
METHODSTo survey the current state of the research methodology, the authors conducted a literature review of all medical and public health journals from January 2002 through the present for English-language articles containing the phrases "disaster medicine" or "public health preparedness" in the title, subject, body, or as key words. The search was conducted using both MEDLINE and PubMed databases, and all duplicates were removed. In addition, all of the articles from the journal Prehospital and Disaster Medicine were included in the analysis, regardless of whether they met the inclusion criteria noted above. Articles excluded were editorials, letters to the editor, or conference abstracts, as well as any articles that focused solely on an emergency medicine or prehospital issue that was not disaster-related. A total of 303 articles were identified. Two of the authors (D.M.A. and A.L.G.) reviewed and coded all of the records independently. All coding discrepancies were discussed and reconciled through a consensual process.All of the articles were coded by the type of research methodology used (eg, survey, secondary data analysis, clinical trial, case study), the primary research objective (eg, descriptive, epidemiological or health services research, evaluation research, guideline development, hypothesis-testing, organizational or policy planning), the primary unit of analysis (eg, individual, organizational, social or communal-level, or political/legal/ethical frameworks), and the primary hazard phase being addressed by the research (eg, prevention or mitigation, preparedness, response or event-phase, short-or long-term recovery). As a group, these selected articles represent the core disciplinary literature in the evolving fields of disaster medicine and public health preparedness.
RESULTSA majority of the articles reviewed were based on qualitative data, reviewed common disaster-related practices or strategies, or presented conceptual frameworks (Table 1). One third of the articles surveyed were review articles and another one four...
