Study summary

The purpose of our randomized controlled trial is to determine whether mailed educational reminders would increase fecal occult blood test (FOBT) card return rates and, therefore, improve patient compliance with colonrectal cancer (CRC) screening.

We will conduct a randomized, controlled trial to evaluate the hypothesis that compliance to FOBT referrals is at least 10% greater among patients who receive mailed educational reminders on the importance of CRC screening. The study will be conducted in Veteran Affairs Medical Center and surrounding VA clinics in San Diego.

Read the detailed description

Colorectal cancer (CRC) is the third most common cancer in men and women in the United States with an estimated 147,000 new cases and more than 56,000 deaths each year. Early detection of colon cancer and removal of precancerous adenomatous polyps have been shown to reduce its morbidity, mortality and incidence. There are several recommended CRC screening tests, including fecal occult blood test (FOBT), flexible sigmoidoscopy, air-contrast barium enema, and colonoscopy. In the VA, FOBT is the predominant screening test for CRC, however patient compliance is low. Numerous studies have evaluated patient participation in CRC screening programs and FOBT card return rates, all of which have shown patient adherence was suboptimal. To date, there are no studies that have evaluated whether mailed educational reminders can improve FOBT compliance. The purpose of our randomized controlled trial is to determine whether mailed educational reminders would increase FOBT card return rates and, therefore, improve patient compliance with CRC screening.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2007 to primary completion in Dec 2009, 30 months.

Of 290 non-industry interventional studies with no phase under Colonic Neoplasms, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 60. This study's 30 months is close to that.

Counting every sponsor, half of 300 studies reached it within 32 months; a quarter within 18 and three quarters within 55.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 17, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
