Prostate cancer is the most commonly diagnosed cancer and the second leading cause of cancer death among men in the United States. The information needs of prostate cancer patients and their families are particularly pressing due to the complexity of treatment options, many of which can significantly impact patients’ quality of life. Older men living in rural areas experience disproportionately higher mortality rates from prostate cancer than peers in urban areas. To address this health disparity, we propose a community outreach and usability study of the Interactive Prostate Cancer Information, Communication, and Support Program (iPICS), an evidence-based and user-centered digital health information platform funded by the U.S. Department of Defense (2021 to July 2025). The iPICS platform integrates authoritative content from MedlinePlus via API with self-curated health education materials developed by healthcare researchers and clinicians. By partnering with rural public libraries as local trusted community hubs, this project aims to bridge the digital divide and address gaps in health literacy and information access by delivering accurate and reliable prostate cancer information to older adults and their families in under-resourced rural regions. Findings from this usability study will inform contextually tailored enhancements to the platform, equip rural libraries with relevant and reliable information resources on prostate cancer, and support their community outreach.
