INTRODUCTION: We aimed to explore primary care physicians' (PCP) attitudes, perceptions, and barriers toward Alzheimer's disease (AD) diagnosis and incorporating blood biomarker (BBM) tests into the diagnostic workflow. METHODS: Remote 60-min interviews with 20 PCPs were conducted (May 2023). Participants included generalists and geriatricians representing urban, suburban, and rural U.S. practices. Interviews encompassed early AD diagnosis, PCP role, and BBM test implementation. RESULTS: Most PCPs view investigating cognitive decline as an important part of their role and are somewhat confident in diagnosing AD. Barriers include the complexity and inefficiency of current diagnostic workflows, lack of effective treatments, and stigma. PCPs consider BBM tests accurate and cost-effective but have concerns about reimbursement and diagnostic pathway placement. DISCUSSION: PCPs are interested in AD diagnosis and receptive toward BBM testing. Education on BBM test use and AD diagnosis may benefit PCPs in the care of individuals with cognitive decline. HIGHLIGHTS: Early Alzheimer's disease (AD) diagnosis is crucial for initiating treatment Primary care physicians (PCPs) find investigation of cognitive decline important PCPs consider blood biomarker (BBM) tests accurate and cost-effective PCPs seek clarity on reimbursement of BBM tests and their context of use Education on BBM test interpretation and AD diagnosis may benefit primary care.
