Opportunities to encourage adoption of a biomarker-enabled care pathway for Alzheimer's in primary care

Abstract

Identification of early-stage Alzheimer's disease (AD) remains a challenge due to limited specialist availability, diagnostic access, disease awareness, and cultural factors. Blood-based biomarkers (BBBM) could play a critical role in the identification and referral of patients suspected of AD to specialty care. A multidisciplinary AD Biomarker Task Force was convened to evaluate current biomarker use cases, define an optimal biomarker-enabled AD diagnostic care pathway, and understand factors impacting adoption. The Task Force identified opportunities to support biomarker-enabled AD diagnostic care pathway adoption, including streamlining risk assessment and screening by leveraging digital tools, activating primary care providers through education, generating data to expand applicability to diverse populations, and advocating for aligned policies and quality measures. Adoption of BBBMs in the primary care setting will be critical to improve early AD detection. However, challenges to pathway adoption persist and will require action from clinicians, payers, policy makers, and patients to address.

Highlights: Blood-based biomarkers can streamline the identification of AD in primary care. Future biomarker-enabled diagnostic care pathways will leverage digital assessments. Education, data generation, and policy advocacy are vital to encourage BBBM use. Implementation of AD care pathways requires the activation of diverse stakeholders.
