Comparative effectiveness of two interventions to increase colorectal cancer screening among females living in the rural Midwest

Abstract

Purpose: To assess the comparative effectiveness of a tailored, interactive digital video disc (DVD) intervention versus DVD plus patient navigation (PN) intervention versus usual care (UC) on the uptake of colorectal cancer (CRC) screening among females living in Midwest rural areas.

Methods: As part of a larger study, 663 females (ages 50-74) living in rural Indiana and Ohio and not up-to-date (UTD) with CRC screening at baseline were randomized to one of three study groups. Demographics , health status/history, and beliefs and attitudes about CRC screening were measured at baseline. CRC screening was assessed at baseline and 12 months from medical records and self-report. Multivariable logistic regression was used to determine whether females in each group were UTD for screening and which test they completed.

Results: Adjusted for covariates, females in the DVD plus PN group were 3.5× more likely to complete CRC screening than those in the UC group (odds ratio [OR] 3.62; 95% confidence interval [CI]: 2.09, 6.47) and baseline intention to receive CRC screening (OR 3.45, CI: 2.21,5.42) at baseline. Adjusting for covariates, there was no difference by study arm whether females who became UTD for CRC screening chose to complete a colonoscopy or fecal occult blood test/fecal immunochemical test.

Conclusions: Many females living in the rural Midwest are not UTD for CRC screening. A tailored intervention that included an educational DVD and PN improved knowledge, addressed screening barriers, provided information about screening test options, and provided support was more effective than UC and DVD-only to increase adherence to recommended CRC screening.
