Abstract Body:
Background: Colorectal cancer (CRC) screening rates are low among Hispanic primary care patients who are 50 to 75 years of age. Effective interventions are needed to raise these rates. Methods: The research team consented 400 Hispanic patients from five primary care practices of the Lehigh Valley Health Network (LVHN) in southeastern Pennsylvania who were eligible for, but were not up to date with CRC screening. We randomized participants either to an SI Group (n=203) or a DSNI Group (n=197). Both groups were sent a CRC screening kit with instructions in English and Spanish (an informational booklet on screening, a stool blood test (SBT), and colonoscopy screening instructions). The DSNI Group also received a telephone call from a bilingual patient assistant (navigator) who reviewed the booklet with each recipient, determined the individual’s preferred screening test and likelihood of adherence, and helped the participant implement a personal screening plan. Follow-up survey and medical records data were used to assess 12-month overall and test-specific screening adherence, screening decision stage, and knowledge and perceptions about screening. Results: CRC screening adherence was significantly higher in the DSNI Group than the SI Group (OR = 4.83). The DSNI Group, compared to the SI Group, also displayed a higher SBT screening rate (OR = 4.20), a higher colonoscopy screening rate (OR = 8.79), and a higher screening decision stage (OR=4.91). There were no significant study group differences in participant screening knowledge or perceptions. Conclusions. The DSNI strategy had a substantially greater positive impact on CRC screening adherence than the SI approach.
