Abstract Background: Despite efforts to integrate genetic cancer risk assessment (GCRA) services into mainstream medicine, the dearth of healthcare providers adequately trained in clinical cancer genetics remains a significant barrier to care, particularly in underserved communities. Since 2001, City of Hope has helped address this need through a distance mediated lntensive Course (IC) and Clinical Cancer Genomics Community of Practice (CCGCoP), with a focus on training and supporting clinicians who deliver care to underserved patient populations. Here we report on the reach, education, and practice outcomes from the past five annual cohorts of the IC in its pursuit to expand GCRA care to underserved areas and minority populations. Methods: Practice catchment area and patient population data were collected on the course application. Cancer genetics knowledge was assessed at baseline and immediate post-course; professional self-efficacy and practice changes were measured at baseline, immediate, and 12 months post-course. Results: Of 762 participants from five IC cohorts (2020-2024), 566 (74%) indicated they provide all or part of their care in an underserved area and/or to minority populations; 55 (10%) practice outside the U.S. Of these 566 clinicians, mean pre-to-post course knowledge scores increased 59%, and mean pre-to-post self-efficacy scores increased by 38%. Of 195 participants who completed a one-year post-course practice survey, 68 (35%) did not practice GCRA at baseline, of whom 61 (88%) reported implementing GCRA into their practice one-year post-course. Of 126 participants who were practicing GCRA at baseline, 55 (44%) reported an increase in their GCRA patient volume at one-year post-course. Open-ended feedback revealed that participants highly valued IC training and ongoing CCGCoP support for building and sustaining their GCRA skills, resources, and practices. Conclusions:Results demonstrate the efficacy of distance-mediated training and ongoing practice support in enhancing clinician competencies and knowledge of practicing GCRA therefore increasing access to GCRA services for underserved and minority patient populations. Efforts are underway to leverage the resources of the IC and CCGCoP to develop a more flexible, cost-effective course model and collaborate with champions to increase access to best practices in GCRA in diverse underserved settings across the US and internationally.
