Brief Summary

Recent improvements in colorectal cancer (CRC) incidence, mortality, stage at diagnosis, and survival in the general U.S. population have been attributed to routine screening with prompt removal of polyps, early detection, and timely and appropriate treatment. American Indians/Alaska Natives (AI/ANs) have not experienced improvements in CRC related outcomes and are significantly less likely than non-Hispanic Whites to receive recommended CRC screening. The purpose of this three-arm randomized controlled trial is to determine the efficacy of interventions designed to enhance CRC screening. The study also uses mixed methods to finalize the intervention and to determine promoters and barriers of screening. The study also conducts process evaluation to determine cost-effectiveness of the interventions, fidelity of study implementation, and to develop plans to sustain and scale-up the intervention model. The study will determine the efficacy of serially implemented interventions of graded intensity for increasing CRC screening using the fecal immunochemical test (FIT) in accordance to recommended guidelines among average risk American Indians (AIs) aged 45-75 residing on reservations in rural Southwestern U.S. Serial implementation refers to offering routine screening, irrespective of response to an earlier invitation, in concordance with guidelines which recommend annual FIT testing between ages 45-75. The FIT is most appropriate because it is an approved, high sensitivity fecal occult blood test and is available at Indian Health Service (IHS) and tribal health facilities where resources to provide screening colonoscopy are limited. The study is a collaborative effort between the Albuquerque Area Indian Health Board (100% Indian-owned and operated), six Pueblo Tribes in rural Southwestern U.S., and the University of New Mexico. Findings from this research could lead to an immediate increase in CRC screening and ultimately reduce CRC burden among AIs, thus addressing national and tribal priorities of reducing CRC disparities among AIs.

Study Arms (3)

High Intensity (Group 1)

EXPERIMENTAL

The high intensity intervention includes: navigated outreach, with four in-depth education outreach sessions; mailed FIT; education material; and follow-up mailed reminders (Group 1). The navigated outreach includes one-on-one information dissemination about CRC, importance of adhering to CRC screening guidelines, identification and solutions to screening barriers, motivation, self-efficacy and comprehension on how to complete the FIT kit, and gathering (if requested) and return of the completed FIT to the laboratory. The educational material (brochure) is specially developed and culturally tailored for the six Tribes recruited for this study. The FIT kit used is the Polymedco OC FIT-CHECK® OC-Light test, which is a single collection test that meets USPSTF's guidelines.

Behavioral: High Intensity (Group 1)

Medium Intensity (Group 2)

EXPERIMENTAL

The medium intensity intervention includes: mailed FIT; education material; and follow-up mailed reminders (Group 2). The educational material (brochure) is specially developed and culturally tailored for the six Tribes recruited for this study. The FIT kit used is the Polymedco OC FIT-CHECK® OC-Light test, which is a single collection test that meets USPSTF's guidelines.

Behavioral: Medium Intensity (Group 2)

Reference Group (Group 3)

EXPERIMENTAL

The reference group (Group 3), per IHS guidelines and current standard of care at participating IHS facilities, receives usual care (ie, screening recommendation and a FIT kit at a clinic visit). The FIT kit used is the Polymedco OC FIT-CHECK® OC-Light test, which is a single collection test that meets USPSTF's guidelines.
