Routine Screening for Colorectal Cancer (U.S. Preventive Services Task Force and CDC) Criteria Asymptomatic Ages 50-75 years Average-risk Tests Colonoscopy every 10 years (many health professionals consider it the GOLD STANDARD) Sigmoidoscopy every 5 years + fecal occult blood test every 3 years Fecal occult blood test (FOBT) every year Guaiac-based fecal occult blood test (gFOBT) Fecal immunochemical test (FIT) Recommendation Summary. U.S. Preventive Services Task Force. October 2008. http://www.uspreventiveservicestaskforce.org/Page/Topic/recommendation-summary/colorectal-cancer-screening

Slide 5

If colonoscopies are so effective, why doesnt everyone just get them?

METHODS An attempt to improve colorectal cancer screening rates

Slide 10

Methods Randomized controlled trial Setting 3 Indian Health Service or tribally-operated health facilities in New Mexico Participants Ages 50-75 Not up-to-date with CRC screening No history of CRC or total colectomy Study groups Group 1: Usual care Group 2: Mail-out Group 3: Mail-out + Community Health Representative (CHR) outreach

Slide 11

Slide 12

Why Community Health Representatives? Trusted and familiar faces in community Liaisons between community members and health clinics Vast majority members of same tribe they work with Already interact with many community members

Slide 13

RESULTS Which delivery mechanism worked best?

Slide 16

DISCUSSION What can we take away from this study?

Slide 17

Limitations CHRs could not carry out all intended outreach due to staff turnover, competing priorities, etc. We cannot determine if significant differences between the mail-out group and mail-out + CHR outreach group would have resulted, had CHRs performed all outreach Results should not be generalized to all American Indian populations

Slide 18

Take-Away Messages Directly mailing FIT kits to individuals eligible for CRC screening increases completion and access to CRC screening. If used widely, this strategy could increase the percentage of AI/ANs who are up-to-date with CRC screening, potentially affecting CRC morbidity and mortality.
