Introduction: Black individuals have 70-80% higher incidence and 120% higher mortality from prostate cancer when compared to all other groups in the US. This is the largest racial disparity in cancer-related mortality in the US and has persisted over the last five decades despite improvements in the diagnosis and treatment of prostate cancer. Our previous work demonstrated that intensified screening practices could reduce prostate cancer mortality among Black individuals. Challenges impede the translation of these findings into real-world interventions and practices. The objective of this study was to design a patient-centered and culturally tailored knowledge toolkit to improve the knowledge and awareness of prostate-specific antigen (PSA) testing in Black individuals to facilitate informed shared-decision making between Black patients and primary care providers. Methods: Using a community-partnered participatory research approach, we convened a working group of Black prostate cancer survivors and community advocates, and clinicians, researchers, and health communications specialists. During monthly meetings, the working group followed Graham’s Knowledge-to-Action framework to synthesize information from: 1) peer-reviewed literature on the use of shared decision-making aids; 2) interviews conducted by our research team with Black individuals regarding barriers and facilitators to access PSA testing; and 3) community input on PSA testing and prostate cancer early detection. We then facilitated four iterative design sessions with the working group to develop recommendations for toolkit content, framing, and format. Results: With the working group, we designed a comprehensive set of resources to increase knowledge and awareness of PSA testing for early detection of prostate cancer among Black individuals. The design framework includes detailed recommendations on the content, framing, and format for resources contained in the toolkit. Recommendations encompass: 1) interactive web-based documents that cover comprehensive information about prostate cancer risk and screening; 2) printable shared decision-making documents that present evidence-based information about the use of PSA testing to guide conversations between Black individuals and their primary care providers; and 3) educational videos focused on prostate cancer fundamentals and dispelling common misconceptions about prostate cancer risk and screening, with content delivered by Black prostate cancer survivors and interviews with Black providers and prostate cancer researchers. Conclusion: This study addressed the need for a community-developed approach to increasing knowledge and awareness about prostate cancer screening and early detection in an accessible, culturally tailored, and accurate manner. We used a collaborative process that centered the experiences of Black prostate cancer survivors and advocates in the design of a toolkit that can facilitate decision-making discussions between Black individuals and their care providers for use of PSA testing for prostate cancer screening.
