Abstract

Background: We tested the efficacy of a remote tailored intervention Tele-Cancer Risk Assessment and Evaluation (TeleCARE) compared with a mailed educational brochure for improving colonoscopy uptake among at-risk relatives of colorectal cancer patients and examined subgroup differences based on participant reported cost barriers. Methods: Family members of colorectal cancer patients who were not up-to-date with colonoscopy were randomly assigned as family units to TeleCARE (N = 232) or an educational brochure (N = 249). At the 9-month follow-up, a cost resource letter listing resources for free or reduced-cost colonoscopy was mailed to participants who had reported cost barriers and remained nonadherent. Rates of medically verified colonoscopy at the 15-month follow-up were compared on the basis of group assignment and within group stratification by cost barriers. Results: In intent-to-treat analysis, 42.7% of participants in TeleCARE and 24.1% of participants in the educational brochure group had a medically verified colonoscopy [OR, 2.37; 95% confidence interval (CI) 1.59-3.52]. Cost was identified as a barrier in both groups (TeleCARE= 62.5%; educational brochure= 57.0%). When cost was not a barrier, the TeleCARE group was almost four times as likely as the comparison to have a colonoscopy (OR, 3.66; 95%CI, 1.85-7.24). The intervention was efficacious among those who reported cost barriers; the TeleCARE group was nearly twice as likely to have a colonoscopy (OR, 1.99; 95% CI, 1.12-3.52). Conclusions: TeleCARE increased colonoscopy regardless of cost barriers. Impact: Remote interventions may bolster screening colonoscopy regardless of cost barriers and be more efficacious when cost barriers are absent.
