Colorectal Cancer Screening

Though colorectal cancer (CRC) screening saves lives, it is not yet being delivered effectively to rural Alaska Native people who have the highest burden of CRC of any racial and/or ethnic group in the US. This population resides in remote communities distributed over a vast state. Though health care facilities serving these populations sometimes have medical staff capable of performing screening flexible sigmoidoscopy or colonoscopy, they are unable to dedicate adequate time to routine screening.

With funding from the CDC Division of Cancer Prevention and Control and technical support from the IHS Division of Epidemiology, the Alaska Native Tribal Health Consortium's Alaska Native Epidemiology Center is leading a variety of projects aimed at increasing CRC screening among Alaska Natives.

To address the need to increase CRC screening awareness among AI/AN in other regions, the Tribal Community Colorectal Health Education & Navigation Program has been established, through a collaboration with the Albuquerque Area Indian Health Board. The primary objectives of this program are to:

  • Build knowledge and skills among tribal community health representatives (CHRs) to bolster their involvement in colorectal health education, outreach and navigational services in the seven AAIHB consortium tribes, and
  • Develop multidisciplinary colorectal health workgroups in participating AAIHB communities to strengthen collaboration between CHRs, clinic providers and other community health providers/programs and expand tribal community colorectal cancer control efforts, and
  • Share successful strategies, materials and lessons learned with tribal communities throughout the country to strengthen local colorectal cancer control efforts.

Linkage Project

Coding of American Indian and Alaska Native (AI/AN) status on death certificates has been shown to be inaccurate. A study performed by the National Center for Health Statistics, linking self-report of race at census/census survey to that reported by the funeral home director when a person dies, reveals as much as 40 percent of AI/AN deaths are not recorded as native. (http://www.cdc.gov/nchs/data/series/sr_02/sr02_148.pdf [PDF] Exit Disclaimer: You Are Leaving www.ihs.gov )

As a way to minimize the effects of racial misclassification and provide improved estimates of mortality among AI/AN, the Indian Health Service (IHS) and CDC supported a linkage between the IHS registration records and the National Death Index (NDI). The resulting analytic file will provide the opportunity to improve mortality reporting for AI/AN.

This linkage project will be reported in a special supplement in the American Journal of Public Health in 2013. The supplement will include papers the leading causes of death - cancer, diabetes, heart disease, stroke, injury, infectious disease, etc. The mortality data included in the supplement will cover the period 1990-2008 and will compare AI/AN rates to non-Hispanic white rates. These data will likely be the most current and accurate mortality data for AI/AN, a group of Americans with generally unfavorable health profiles. The data and publications should be a resource for health planning in a context of renewed attention on health disparities.
