Patient Test Preference for Colorectal Cancer Screening and Screening Uptake in an Insured Urban Minority Population

The study examines the role of patient colorectal cancer (CRC) screening test preference and CRC screening uptake in an insured, urban minority population. Study subjects were enrolled in a randomized controlled trial to promote CRC screening. The interventions were educational, with an emphasis on colonoscopy screening. Subjects were 50+ years of age, fully insured for CRC screening, and out of compliance with current CRC screening recommendations. This paper includes those who answered a question about CRC screening test preference and indicated that they intended to receive such a test in the coming year (n = 453). CRC screening uptake was ascertained from medical claims data. Regardless of test preference, few received CRC screening (22.3 %). Those preferring the home stool test (HST) were less likely to get tested than those preferring a colonoscopy (16.6 vs 29.9 %, χ² = 9.9, p = .002). Preference for HST was more strongly associated with beliefs about colonoscopy than with knowledge about colonoscopy. In the context of an RCT emphasizing colonoscopy screening for CRC, patients expressing a preference for HST are at heightened risk of remaining unscreened. Colonoscopy should be recommended as the preferred CRC test, but HSTs should be accessible and encouraged for patients who are averse to colonoscopy.
