DESCRIPTION (provided by applicant): The utility of routine screening for prostate cancer with prostate specific antigen (PSA), remains highly controversial, and is not recommended by the United States Preventive Services Task Force, although it may be justified at the individual patient level. Many primary care physicians (PCPs) order PSA without helping patients understand the associated risks, benefits and downstream consequences. Shared decision-making (SDM) is an important component of high quality care which correlates with positive health outcomes, consumer demand, and a moral imperative to consider patients as persons. Ways to improve SDM include (1) "patient activation" interventions to increase patient participation in care and (2) physician interventions to improve the consultation process. We will test whether an intervention to improve SDM will improve physician and patient knowledge, skills and attitudes about PSA screening, and change PCP PSA screening practices. In a unique public-private partnership, we will recruit 145 PCPs across four health systems in California (UC Los Angeles, UC Davis, Rural Health Network, Kaiser Permanente). We will sample PCPs and patients from all major socio-demographic areas across the state. PCPs will be randomized by practice site to control (paper curriculum) or active intervention with an interactive web-based curriculum previously developed with funding from the CDC. This curriculum utilizes visual tools, video clip vignettes, and other interactive content to illustrate key points about risk assessment, PSA screening, and SDM.. In addition, patients at intervention sites will be randomized to receive either the same brochure as patients at control sites, or a further active intervention consisting of a CD-funded interactive curriculum covering similar content from a patient perspective. Both intervention groups (PCPonly or physician and patient intervention) will be compared to controls regarding knowledge, skills and attitudes. The primary endpoint will be changes in physician SDM behavior (Kaplan scale). Pre.-and post-test changes in PCP knowledge and attitudes will also be assessed, and post-intervention PCP SDM skills will be assessed using unannounced standardized patients, who present to PCP offices with a request for PSA testing. Post-test patient changes in knowledge and attitudes will also be assessed. Finally, any change in actual PSA ordering behaviors will be assessed. In summary, we will evaluate the ability of an educational intervention to improve the care of patients, both by activating/informing patients, and by providing PCPs with tools to engage patients more effectively. If proven effective, these web-based tools can be easily disseminated around the country, and internationally, to improve knowledge and attitudes about PSA screening among physicians and patients.

描述（由申请人提供）：使用前列腺特异性抗原（PSA）对前列腺癌进行常规筛查的效用仍然存在很大争议，并且美国预防服务工作组不建议这样做，尽管在个体患者水平上可能是合理的。许多初级保健医生 (PCP) 在没有帮助患者了解相关风险、益处和下游后果的情况下就进行了 PSA 治疗。共同决策 (SDM) 是高质量护理的重要组成部分，它与积极的健康结果、消费者需求以及将患者视为人的道德要求相关。改进 SDM 的方法包括 (1) “患者激活”干预措施，以增加患者对护理的参与；(2) 医生干预措施，以改善咨询过程。我们将测试改善 SDM 的干预措施是否会提高医生和患者对 PSA 筛查的知识、技能和态度，并改变 PCP PSA 筛查实践。在独特的公私合作伙伴关系中，我们将在加利福尼亚州的四个卫生系统（加州大学洛杉矶分校、加州大学戴维斯分校、农村卫生网络、凯撒医疗机构）招募 145 名 PCP。我们将对全州所有主要社会人口区域的 PCP 和患者进行抽样。 PCP 将按实践地点随机分配，以进行控制（纸质课程）或使用先前由 CDC 资助开发的交互式网络课程进行积极干预。本课程利用视觉工具、视频片段和其他互动内容来说明有关风险评估、PSA 筛查和 SDM 的要点。此外，干预地点的患者将被随机分配接受与对照地点患者相同的手册，或进一步的积极干预，包括 CD 资助的互动课程，从患者的角度涵盖类似的内容。两个干预组（仅 PCP 或医生和患者干预）都将与对照组的知识、技能和态度进行比较。主要终点是医生 SDM 行为的变化（卡普兰量表）。还将评估 PCP 知识和态度测试前和测试后的变化，并使用未经通知的标准化患者评估干预后 PCP SDM 技能，这些患者向 PCP 办公室提出 PSA 测试请求。还将评估测试后患者知识和态度的变化。最后，将评估实际 PSA 订购行为的任何变化。总之，我们将评估教育干预改善患者护理的能力，方法是激活/告知患者，并为 PCP 提供更有效地吸引患者的工具。如果被证明有效，这些基于网络的工具可以轻松地在全国和国际范围内传播，以提高医生和患者对 PSA 筛查的了解和态度。
