Item A Spatial-Temporal Approach to Surveillance of Prostate Cancer Disparities in Population Subgroups(National Medical Association, 2007-01-10) Hsu, Chiehwen Ed; Soto Mas, Francisco; Nkhoma, Ella; Miller, JerryBackground: Prostate cancer mortality disparities exist among racial/ethnic groups in the United States, yet few studies have explored the spatiotemporal trend of the disease burden. To better understand mortality disparities by geographic regions over time, the present study analyzed the geographic variations of prostate cancer mortality by three Texas racial/ethnic groups over a 22-year period. Methods: The Spatial Scan Statistic developed by Kulldorff et al was used. Excess mortality was detected using scan windows of 50% and 90% of the study period and a spatial cluster size of 50% of the population at risk. Time trend was analyzed to examine the potential temporal effects of clustering. Spatial queries were used to identify regions with multiple racial/ethnic groups having excess mortality. Results: The most likely area of excess mortality for blacks occurred in Dallas-Metroplex and upper east Texas areas between 1990 and 1999; for Hispanics, in central Texas between 1992 and 1996; and for non-Hispanic whites, in the upper south and west to central Texas areas between 1990 and 1996. Excess mortality persisted among all racial/ethnic groups in the identified counties. The second scan revealed that three counties in west Texas presented an excess mortality for Hispanics from 1980–2001. Many counties bore an excess mortality burden for multiple groups. There is no time trend decline in prostate cancer mortality for blacks and non-Hispanic whites in Texas. Conclusion: Disparities in prostate cancer mortality among racial/ethnic groups existed in Texas. Central Texas counties with excess mortality in multiple subgroups warrant further investigation.Item Assessing the Readiness and Training Needs of Non-urban Physicians in Public Health Emergency and Response(Harvard School of Public Health, Center for Public Health Preparedness, 2005-10) Hsu, Chiehwen Ed; Soto Mas, Francisco; Jacobson, Holly; Nkhoma, Ella; Zoretic, JamesEmergency readiness has become a public health priority for United States communities after the 9/11 attacks. Communities that have a less developed public health infrastructure are challenged to organize preparedness and response efforts and to ensure that health care providers are capable of caring for victims of terrorist acts. A survey was used to assess nonurban physicians’ prior experience with and selfconfidence in treating, and preferred training needs for responding to chemical, biologic, radiologic, nuclear, and explosive (CBRNE) cases. Data were collected through a mailed and Web-based survey. Although the response rate was calculated at 30%, approximately one third of the surveys were not able to be delivered. Most respondents reported never having seen or treated CBRNE-inflicted cases and were not confident in their ability to diagnose or treat CBRNE cases, but many were willing to participate in a state-led response plan. Almost half of the individuals had not participated in any related training but expressed interest in receiving training in small group workshops or through CD-ROM. These results provide potential direction for strategic preparedness planning for non-urban health care providers.Item Public Health Preparedness of Health Providers: Meeting the Needs of Diverse, Rural Communities(2006-11) Hsu, Chiehwen Ed; Soto Mas, Francisco; Jacobson, Holly; Harris, Ann Marie; Nkhoma, Ella; Hunt, VictoriaMeeting the needs of public health emergency and response presents a unique challenge for health practitioners with primary responsibilities for rural communities that are often very diverse. The present study assessed the language capabilities, confidence and training needs of Texas rural physicians in responding to public health emergencies. In the first half of year 2004, a cross-sectional, semistructured survey questionnaire was administered in northern, rural Texas. The study population consisted of 841 practicing or retired physicians in the targeted area. One-hundred-sixty-six physicians (30%) responded to the survey. The responses were geographically referenced in maps. Respondents reported seeing patients with diverse cultural backgrounds. They communicated in 16 different languages other than English in clinical practice or at home, with 40% speaking Spanish at work. Most were not confident in the diagnosis or treatment of public health emergency cases. Geographic information systems were found useful in identifying those jurisdictions with expressed training and cultural needs. Additional efforts should be extended to involve African-American/Hispanic physicians in preparedness plans for providing culturally and linguistically appropriate care in emergencies.
