BackgroundThis study was a randomized trial to test the impact of an informed decision-making intervention on prostate cancer screening use.MethodsThe study population included 242 African-American men from three primary care practices who were 40-69 years of age and had no history of prostate cancer. Participants completed a baseline survey questionnaire and were randomly assigned either to a Standard Intervention (SI) group (N=121) or an Enhanced Intervention (EI) group (N=121). An informational booklet was mailed to both groups. EI group men were also offered a screening decision education session. Two outcomes were considered: (1) complete screening (i.e., having a digital rectal exam (DRE) and prostate specific antigen (PSA) testing), and (2) complete or partial screening (i.e., having a PSA test with or without DRE). An endpoint chart audit was performed six months after initial intervention contact. The data were analyzed via exact logistic regression.ResultsOverall, screening use was low among study participants. EI group men had a screening frequency two times greater than that of SI group men, but the difference was not statistically significant: 8% vs. 4 % (OR = 1.94) fo rcomplete screening, and 19% vs. 10% (OR = 2.08) for complete or partial screening. Multivariable analyses showed that being in the EI group and primary care practice were significant predictors of complete or partial screening (OR = 3.9 and OR = 5.64, respectively).ConclusionProstate cancer screening use may be influenced by exposure to decision education and the influence of screening-related primary care practice factors.
