Effect of a Prostate Cancer Screening Decision Aid for African-American Men in Primary Care Settings

Background: African-American men have an elevated risk of developing and dying from prostate cancer. Shared decision-making (SDM) about prostate cancer screening is recommended but does not always occur. Methods: We pilot-tested an online decision aid (DA) in primary care settings using a pre/postevaluation design among African-American men ages 45 to 70 years. Men completed surveys before and after using the DA, which had interactive segments ( e.g., values clarification) and provided individualized assessment of prostate cancer risk. Primary outcomes included prostate cancer knowledge, confidence in ability to make informed decisions, decisional conflict, and satisfaction with the decision. Immediately after the clinical visit, patients reported the degree to which they were engaged by their provider in SDM. Results: Among this sample of men (n = 49), use of the DA was associated with increased knowledge about prostate cancer [mean = 55.3% vs. 71.2%; 95% confidence interval (CI), 9.8-22.1; P < 0.001], reduced decisional conflict (mean = 33.4 vs. 23.6; 95% CI, -18.1 to -1.6; P = 0.002) on a scale from 0 to 100, and a decreased preference to be screened (88% vs. 69%; 95% CI, 0.09-0.64; P = 0.01). Most (89%) reported that the DA prepared them well/very well for SDM with their provider. Following the clinical visit with providers, scores on perceived involvement in SDM were 68.1 (SD 29.1) on a 0 to 100 scale. Conclusions: The DA improved men's knowledge, reduced decisional conflict, and promoted the perception of being prepared for SDM. Impact: Findings suggest that use of an online DA to improve SDM outcomes warrants further testing in a future trial.
