ObjectiveCalifornia law (Grant H. Kenyon Prostate Cancer Detection Act) requires physicians to inform all patients older than aged 50 years who receive a prostate examination about the availability of the prostate-specific antigen (PSA) test. Physicians are not given guidance on how this information should be presented. We sought to evaluate the effects upon PSA screening rates of informing patients about PSA testing by 2 different techniques.DesignFactorial comparison of discussion versus video formats for presenting information about the PSA test.SettingPatients were recruited through the Health Appraisal screening program in the Department for Preventive Medicine, Kaiser Permanente, San Diego, Calif.ParticipantsMale patients undergoing health appraisal screening participated in 1 of 4 groups providing information about PSA screening: usual care ( n=43), discussion about risks and benefits of PSA ( n=45), shared decision-making video ( n=46), or video plus discussion ( n=42). Participants were sequentially assigned to 1 of the 4 groups.ResultsNo significant differences in demographics or family history was demonstrated between the groups at the time of group assignment. Participants in the intervention groups rated the information as clear, balanced, and fair. There were significant differences in the number of men requesting a PSA test, with the highest rate in the usual care group (97.7%), followed by discussion (82.2%), video (60.0%), and video plus discussion (50.0%).ConclusionProviding information about PSA screening in the form of video or discussion is feasible and significantly alters PSA screening rates.
