A decision aid to promote appropriate colorectal cancer screening among older adults: a randomized controlled trial.
The purpose of this study was to test a patient decision aid (PtDA) to promote CRC screening in older adults. The PtDA was designed to facilitate individual decision-making to help patients understand the potential risks and benefit of CRC screening. 424 patients aged 70 – 84 who were not up to date with CRC screening participated in a double-blinded randomized controlled trial, using the PtDA or an attention control. Two outcomes - appropriate CRC screening behavior at 6 months following the initial visit or appropriate screening intent immediately after the visit - were defined as completed screening or intent for patients in good health, discussion about screening with their provider for patients in intermediate health, or no screening or intent for patients in poor health. Appropriate screening behavior at 6 months was higher in the intervention group; appropriate screening intent following the provider visit was also higher. The authors conclude that the PtDA for older adults promoted appropriate CRC screening behavior.

An entertainment-education colorectal cancer screening decision aid for African American patients: a randomized controlled trial.
The purpose of this study was to assess whether an entertainment-education decision aid tailored for African American patients improved patients' decision making, attitudes, intentions, or colorectal cancer screening behavior. It found that viewing the culturally tailored decision aid significantly increased African American patients' knowledge of colorectal cancer screening recommendations and options. It also significantly reduced their decisional conflict and improved their self-advocacy.

Patient decision aids for colorectal cancer screening: a systematic review and meta-analysis.
This systematic review describes studies evaluating patient decision aids for colorectal cancer screening in average-risk adults and their impact on knowledge, screening intentions, and uptake. It concluded that decision aids improve knowledge and interest in screening, and lead to increased screening over no information, but their impact on screening is similar to general colorectal cancer screening information.
