To date, little research has been reported concerning the impact of CRC screening test preference on screening adherence. It has been suggested that providing patients access to their preferred CRC screening test is a new strategy that could further boost screening adherence ( 7–9). Cancer Epidemiol Biomarkers Prev 22(1) 109–17. Research is needed to determine how preference, access, and navigation affect screening outcomes. Impact: Mailed screening tests can boost adherence. TNI versus SI impact had a modest positive impact on adherence and a pronounced effect on SDS. Secondary analyses indicate that tailored navigation boosted preferred test use, and suggest that intervention impact on adherence and SDS was attenuated by limited access to screening options.Ĭonclusions: Both interventions had significant, positive effects on outcomes compared with usual care. Positive SDS change (TNI Group: +45%, SI Group: +37%, and Control Group: +23%) was significantly greater among intervention recipients than controls ( P = 0.001 and P = 0.001, respectively), and the intervention group difference approached significance ( P = 0.053). Results: The primary outcome, screening adherence (TNI Group: 38%, SI Group: 33%, Control Group: 12%), was higher for intervention recipients than controls ( P = 0.001 and P = 0.001, respectively), but the two intervention groups did not differ significantly ( P = 0.201). Multivariable analyses assessed intervention impact on adherence and change in SDS at 6 months. The SI Group was sent both colonoscopy instructions and stool blood tests. TNI Group participants were sent colonoscopy instructions and/or stool blood tests according to reported test preference, and received a navigation call. Methods: Primary care patients ( n = 945) were surveyed and randomized to a Tailored Navigation Intervention (TNI) Group ( n = 312), Standard Intervention (SI) Group ( n = 316), or usual care Control Group ( n = 317). Background: This randomized, controlled trial assessed the impact of a tailored navigation intervention versus a standard mailed intervention on colorectal cancer screening adherence and screening decision stage (SDS).
