Clinical Trial Summary
Alaska Native men have the highest rates of colorectal cancer incidence and mortality in the
US. Screening can prevent disease and improve survival. We previously developed an
intervention that uses text messages to increase colorectal cancer screening in Alaska Native
patients of the Southcentral Foundation healthcare system in Anchorage, Alaska. The
intervention improved screening by 50% in women, but it had no effect in men. We propose to
culturally tailor the intervention for Alaska Native Men, and to test it with a randomized
controlled trial among 600 patients at the Southcentral Foundation. This will be the first
trial of an intervention designed to increase colorectal cancer screening in Alaska Native
men.
Description:
Alaska Native men have higher colorectal cancer (CRC) incidence and mortality than any other
US racial or ethnic group. Screening can prevent CRC and improve treatment outcomes by
detecting disease in early stages, but Alaska Native men also have low CRC screening uptake.
Colonoscopy is the most accurate CRC screening method and results in the most years of life
saved. It only requires rescreening every 10 years, but it is a clinic- based procedure and
needs extensive preparation. Other screening options include home-based tests that detect
blood in the stool and require rescreening every year. More recently, a home-based method has
been developed that tests stool for DNA indicative of CRC and requires rescreening every 3
years. Current guidelines recommend CRC screening for average risk adults starting between
ages 45-50, but people at higher risk should start at younger ages. Many interventions have
been developed to promote CRC screening. Among these, interventions that use text messaging
or other electronic health messages to reach people outside of the clinical setting have
shown promise for improving CRC screening. In a previous study, our research team developed
an intervention that sends up to 3 text messages to Alaska Native people patients of the
Southcentral Foundation (SCF) healthcare system in Anchorage, Alaska. We tested the
intervention in a randomized controlled trial with 2,386 Alaska Native SCF patients ages
40-75. The intervention increased CRC screening by 50% in women, but it had no effect in men.
In the current implementation study, we propose a theory-based approach to culturally tailor
the existing text message intervention for Alaska Native men. We will use surveys and focus
groups with SCF patients, and key informant interviews with SCF healthcare providers, to
assess barriers and facilitators to optimize colorectal cancer screening in Alaska Native
men. We anticipate that revisions will include changing the content and frequency of the text
messages, and promoting home-based stool DNA screening in addition to colonoscopy. We will
then test the effectiveness of the tailored intervention with 600 Alaska Native men ages
40-75 who are active patients at SCF. Eligible men will be identified from the electronic
medical record and randomized in equal proportions to the intervention or usual care control
conditions. The primary outcome is CRC screening completed within 6 months of sending the
first text message. Secondary outcomes include clinical findings and follow-up procedures
associated with screening. All data will be collected from the electronic medical record, and
we will obtain a waiver of consent for direct patient recruitment. Follow-up interviews will
assess patient response to the intervention. If effective, this study has implications for
increasing CRC screening in men from other racial and ethnic minority groups who experience
CRC disparities.
