- A choice between scheduling a colonoscopy and fecal immunochemical testing (FIT) led to no change in colorectal cancer (CRC) screening completion.
- Colonoscopy popularity fell as FIT kits became more readily available.
Why this matters
- Offering colonoscopy alone may imply that it is the default option.
- Randomized controlled trial (n=438; 55.0% women).
- Participants received mailed outreach about CRC screening. Participants were randomly assigned to direct phone number to call for scheduling colonoscopy (colonoscopy only), direct phone number to call for colonoscopy plus a mailed FIT kit if they did not respond within 4 weeks (sequential choice), or both colonoscopy phone number and a mailed FIT kit (active choice).
- Funding: NIH.
- Median patient age, 56 years (range, 50-74 years; interquartile range, 52-63 years).
- After 4 months, there was no statistically significant difference in CRC screening completion between the colonoscopy-only arm (14.4%), the sequential choice arm (17.1%), and the active choice arm (19.9%). There was also no significant difference at 6 months.
- Of those who completed CRC screening by 4 months, the colonoscopy rate was highest in the colonoscopy arm (90.5%; 95% CI, 78.0%-103.0%), followed by the sequential choice arm (52.0%; P=.005) and the active choice arm (37.9%; P<.001>
- No mailed FIT-only arm.
