Abstract

Background: Provider recommendation is a predictor of colorectal cancer (CRC) screening. Purpose: To compare the effects of two clinic-based interventions on patient-provider discussions about CRC screening. Design: Two-group RCT with data collected at baseline and 1 week post-intervention. Setting/participants: African-American patients that were non-adherent toCRCscreening recommendations (n693) with a primary care visit between 2008 and 2010 in one of 11 urban primary care clinics. Intervention: Participants received either a computer-delivered tailoredCRCscreening intervention or a nontailored informational brochure aboutCRCscreening immediately prior to their primary care visit. Main outcome measures: Between-group differences in odds of having had a CRC screening discussion about a colon test, with and without adjusting for demographic, clinic, health literacy, health belief, and social support variables, were examined as predictors of a CRC screening discussion using logistic regression. Intervention effects onCRCscreening test order by PCPs were examined using logistic regression. Analyses were conducted in 2011 and 2012. Results: Compared to the brochure group, greater proportions of those in the computer-delivered tailored intervention group reported having had a discussion with their provider about CRC screening (63% vs 48%, OR1.81, p>0.001). Predictors of a discussion about CRC screening included computer group participation, younger age, reason for visit, being unmarried, colonoscopy self-efficacy, and family member/friend recommendation (all p-values>0.05). Conclusions: The computer-delivered tailored intervention was more effective than a nontailored brochure at stimulating patient-provider discussions about CRC screening. Those who received the computer-delivered intervention also weremorelikely to have aCRCscreening test (fecal occult blood test or colonoscopy) ordered by their PCP.
