PROJECT SUMMARY More than 6 million people in the United States currently live with Alzheimer's disease and related dementias (ADRD), and this number is expected to more than double by 2050. Research has shown that over the course of disease progression, persons with ADRD have considerable healthcare needs and utilization, often with poor outcomes resulting from that care. Existing research is largely quantitative, despite increased emphasis placed on the value of engaging directly with persons with ADRD about their lived experiences. Further, qualitative approaches are needed to provide insights into how and why quantitative outcomes occur. Thus, the overall objective of Core B is to characterize the underlying mechanisms by which healthcare outcomes for persons with ADRD are achieved through qualitative approaches that include obtaining perspectives from a variety of key informants including healthcare providers, payers, caregivers, and persons living with ADRD themselves. Core B will centrally unify primary data collection activities of the P01 and serve all four proposed research Projects, implementing a series of case studies that will collect data used across all Projects. In addition, Core B will develop and integrate partner advisory panels, which will provide critical insights into considerations about translating P01 findings, across Projects and Cores, into policy and practice. The aims of Core B are: 1. To characterize how policies and market forces (structures) and provider and payer behavior and relationships (processes) influence healthcare choice, access, use, and ultimately outcomes for persons with ADRD across settings of care. This will be accomplished by conducting case studies in eight healthcare markets around the country; and 2. To contextualize and translate findings to inform policy and practice based on feedback and recommendations from our partner engagement panels, representing "systems-level" and "lived experience" perspectives. Through quarterly engagement meetings, the perspectives gathered from key informants will inform the integration of qualitative data generated by Core B with the quantitative data of the four Projects as well as facilitate the translation of research findings into policy and practice. Completion of these aims is aligned with the National Plan to Address Alzheimer's Disease goals of enhancing care quality and efficiency and expanding supports for persons with ADRD and their families. Explicitly, by gathering perspectives from those for whom the findings are most relevant--healthcare payers and providers and persons with ADRD--we expect implications will be actionable and translatable into policy and practice.
