Official title
Systems of Support to Increase Colon Cancer Screening and Follow-up
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
SOS is a four-arm randomized controlled study of ways to increase screening for colorectal cancer. About 40-50% of the people age 50 and older are not up to date on screening. This is a very important problem because screening both prevents colorectal cancer and decreases colon cancer deaths. We are studying 3 different levels of support to help people get screened and follow-up after positive screening tests. These involve comparing to usual care stepwise increasing in intensity approaches; an automated approach of mailing information and home screening tests, this plus phone assistance by a medical assistant, both of these plus phone counseling and care management. We will also compare nurse assisted follow-up after a positive screening test compared to usual care By doing this study we hope to increase colon cancer screening rates, and also follow-up rates for positive screening tests.
