RDAC - SUMMARY The Research and Data Analysis Core (RDAC) will support partnerships between E-STAR scholars and primary care organizations (PCOs) to execute collaborative LHS research projects. We will ensure the success and utility of LHS projects at 4 Federally Qualified Health Centers (FQHCs)—Community Health Association of Spokane, Community Health of Central Washington in Eastern Washington, Healthpoint, NeighborCare—and one integrated health system—Kaiser Permanente Washington (KPWA). We will also serve in an advisory role for the LHS scholar embedded at Veterans Affairs Puget Sound (VA). This Core will be co-led by Drs. Coley (Kaiser Permanente Washington Health Research Institute [KPWHRI]) and Ornelas (University of Washington [UW]) who bring expertise in quantitative and qualitative methods, participatory approaches, patient centered methods, comparative effectiveness and health equity. The RDAC will conduct a needs assessment with FQHCs to identify potential LHS research projects, using systematic evidence reviews, meetings, and in-depth interviews with community members and stakeholders. The assessment will evaluate FQHC readiness and capacity for research collaboration in priority areas by analyzing health system data availability and quality. The RDAC will partner with PCOs and LHS scholars to plan and execute collaborative research projects. A focus throughout study design and implementation will be enhancing PCO capacity and LHS scholar skills. Our approach is informed by PCORI methodology standards and community-based participatory research (CBPR), focusing on identifying evidence gaps, researching potential patient-centered solutions, and disseminating evidence to improve care delivery and health equity. Once projects are complete, the RDAC will facilitate dissemination and implementation of project findings to the learning community and external audiences. This will include partnering with PCOs to implement proven interventions to improve primary care. Dissemination activities targeted to health care organizations will support clinical practice, policy advocacy and long-term organizational changes. RDAC will also assist with preparing dissemination products (e.g., reports, toolkits, and published manuscripts) for diverse audiences. Our ultimate goal is to support primary care organizations in achieving the Quintuple Aim outcomes of health equity, clinician well-being, better health for patients, improved population health, and lower costs.
