Increasing Colorectal Cancer Screening in African Americans
Recruitment status was: Recruiting
RATIONALE: Screening may help doctors find colorectal cancer sooner, when it may be easier to treat. Finding out what affects a patient's decision to undergo screening tests may help increase the number of patients who undergo regular screening for cancer. It is not yet known whether personalized invitations to undergo colorectal cancer screening are more effective than standard screening reminders.
PURPOSE: This randomized phase III trial is studying ways to increase colorectal cancer screening in African Americans.
Other: informational intervention
Other: medical chart review
Other: screening questionnaire administration
Other: study of socioeconomic and demographic variables
Procedure: barium enema injection
Procedure: colon imaging study
Procedure: screening colonoscopy

- To assess the intervention impact on colorectal cancer (CRC) screening utilization over a 6-month observation period in African-American participants.
- To assess the intervention impact on CRC screening preference, classified into three levels (i.e., "decided not to screen or never heard of," "undecided," or "decided to screen"), based on data obtained from both the endpoint chart audit and the endpoint survey.
- To assess intervention impact on population health-management representations related to CRC screening, as assessed by perceived salience and coherence and self-efficacy related to CRC screening measured with 6 to 10 Likert-type items on both the baseline and endpoint surveys.
- To analyze intervention cost-effectiveness, from the societal perspective and from the more limited perspective of the provider and payer, focusing on the average and incremental cost per additional person who is compliant (i.e., has a CRC screening test during the observation period) for each alternative intervention and estimate the cost per life-year saved.
OUTLINE: This is a multicenter study. Participants are stratified according to practice. Participants are randomized to 1 of 2 intervention arms.
- Arm I (standard-intervention group): Participants receive a personalized screening invitation letter encouraging selection and performance of one of the screening tests, a generic colorectal cancer (CRC) screening informational booklet, stool blood testing (SBT) cards, and instructions for arranging a colonoscopy screening appointment. After 45 days, participants who have not been screened receive a reminder letter.
- Arm II (tailored-navigation intervention group): Participants receive a CRC screening invitation letter and materials that are tailored to the individual's preferred screening test strategy (i.e., SBT; SBT and instructions for arranging flexible sigmoidoscopy, instructions for arranging flexible sigmoidoscopy; or instructions for arranging colonoscopy). After 30 days, participants who have not been screened will receive a reminder by telephone. Those participants who have undergone screening will be congratulated for taking the time and preventative action, and be encouraged to continue future screenings. After 45 days, participants who have not been screened receive a reminder letter.
Participants are assessed by a baseline survey consisting of personal background, cognitive and psychological representations, social support and influence, intention, and decision stage related to screening SBT and colonoscopy preference. Data obtained from the endpoint survey assessing whether participants and their providers discussed CRC screening before the study and opinions about the intervention, and an endpoint chart audit to gather data on participant CRC screening exam dates and exam results (i.e., screening SBT, flexible sigmoidoscopy, colonoscopy, double-contrast barium enema [DCBE] x-ray) are assessed for group differences.
