Abstract

Introduction: Clinicians' views on the clinical readiness of Alzheimer's disease (AD) blood biomarkers (BBMs) are not well understood.

Methods: The Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment Biofluid-Based Biomarkers Professional Interest Area conducted a survey to elicit clinician opinions on AD BBM implementation, including contexts of use, assay selection, reporting, and result interpretation.

Results: Clinician respondents (n = 212) practiced in Europe (56%), North America (24%), the Caribbean and Central/South America (11%), and other continents (9%). Most respondents were medical doctors (80%) practicing in secondary or tertiary care (88%). For 56%, cerebrospinal fluid AD biomarkers or amyloid positron emission tomography were accessible, but 48% agreed and 52% disagreed with the implementation of AD BBMs in any clinical context. Respondents emphasized the need for data from diverse populations and educational resources to support test interpretation.

Discussion: Surveyed clinicians generally agreed with published appropriate use recommendations but were divided on AD BBM readiness for clinical use.

Highlights: A survey of clinicians was conducted regarding clinical readiness of Alzheimer's disease (AD) blood biomarkers (BBMs). Views were split on AD BBM clinical readiness: 48% agreed, 52% disagreed. Most responders supported AD BBM use for treatment decisions. Most responders opposed AD BBM testing in asymptomatic individuals. Test performance data and educational materials to aid interpretation were of high importance.
