The objective of this study was to estimate the burden of cancer in counties affected by Hurricane Katrina using population-based cancer registry data, and to discuss issues related to cancer patients who have been displaced by disasters.
The cancer burden was assessed in 75 counties in Louisiana, Alabama, and Mississippi that were designated by the Federal Emergency Management Agency as eligible for individual and public assistance. Data from the National Program of Cancer Registries were used to determine three-year average annual age-adjusted incidence rates and case counts during the diagnosis years 2000-2002 for Louisiana and Alabama. Expected rates and counts for the most-affected counties in Mississippi were estimated by direct, age-specific calculation using the 2000-2002 county level populations and the site-, sex-, race-, and age-specific cancer incidence rates for Louisiana.
An estimated 23,549 persons with a new diagnosis of cancer in the past year resided in the disaster-affected counties. Fifty-eight percent of the cases were cancers of the lung/bronchus, colon/rectum, female breast, and prostate. Eleven of the top 15 cancer sites by sex and black/white race in disaster counties had >50% of cases diagnosed at the regional or distant stage.
Sizable populations of persons with a recent cancer diagnosis were potentially displaced by Hurricane Katrina. Cancer patients required special attention to access records in order to confirm diagnosis and staging, minimize disruption in treatment, and ensure coverage of care. Cancer registry data can be used to provide disaster planners and clinicians with estimates of the number of cancer patients, many of whom may be undergoing active treatment.

    • "While identifying and implementing tailored recruitment strategies are critical and underdeveloped, intentional involvement of community leaders and other community based participatory research strategies are also much needed areas for development with promise for reducing disparities in research participation. Though less commonly used, population-based registries are also used for study recruitment and are most often used to recruit research study participants that share a common characteristic such as illness [25] [26] [27] [28] [29] [30] [31] [32] [33] [34] [35] [36] [37]. Less is known about the use of registries designed specifically to increase minority participation in research studies. "

    ABSTRACT: Introduction: Prevention and treatment standards are based on evidence obtained in behavioral and clinical research. However, racial and ethnic minorities remain relatively absent from the science that develops these standards. While investigators have successfully recruited participants for individual studies using tailored recruitment methods, these strategies require considerable time and resources. Research registries, typically developed around a disease or condition, serve as a promising model for a targeted recruitment method to increase minority participation in health research. This study assessed the tailored recruitment methods used to populate a health research registry targeting African-American community members. Methods: We describe six recruitment methods applied between September 2004 and October 2008 to recruit members into a health research registry. Recruitment included direct (existing studies, public databases, community outreach) and indirect methods (radio, internet, and email) targeting the general population, local universities, and African American communities. We conducted retrospective analysis of the recruitment by method using descriptive statistics, frequencies, and chi-square statistics. Results: During the recruitment period, 608 individuals enrolled in the research registry. The majority of enrollees were African American, female, and in good health. Direct and indirect methods were identified as successful strategies for subgroups. Findings suggest significant associations between recruitment methods and age, presence of existing health condition, prior research participation, and motivation to join the registry. Conclusions: A health research registry can be a successful tool to increase minority awareness of research opportunities. Multi-pronged recruitment approaches are needed to reach diverse subpopulations.

    ABSTRACT: Current disaster taxonomy describes diversity, distinguishing characteristics, and common relations in disaster event classifications. The impact of compromised public health infrastructure and systems on health consequences defines and greatly influences the manner in which disasters are observed, planned for, and managed, especially those that are geographically widespread, population dense, and prolonged. What may first result in direct injuries and death may rapidly change to excess indirect illness and subsequent death as essential public health resources are destroyed, deteriorate, or are systematically denied to vulnerable populations. Public health and public health infrastructure and systems in developed and developing countries must be seen as strategic and security issues that deserve international public health resource monitoring attention from disaster managers, urban planners, the global humanitarian community, World Health Organization authorities, and participating parties to war and conflict. We posit here that disaster frameworks be reformed to emphasize and clarify the relation of public health emergencies and modern disasters.
