Establishing Clinical Utility Evidence for a Novel Alzheimer's Disease Blood-Based Biomarker Assay

QURE Healthcare will recruit a nationwide sample of neurologists and dementia specialists to assess the clinical evaluation and management potential of a novel diagnostic tool. The results of this study are expected to contribute to improved quality of care for patients with symptoms of Alzheimer's disease. Findings from this study will be submitted to a national journal for peer-reviewed publication. This study plans to enroll at least 150 healthcare providers.

This study will evaluate the clinical utility of Alzheimer's disease assay by analyzing improvement in the quality of physician decision-making regarding patients with symptoms of Alzheimer's disease, using a validated patient-simulation-based measurement approach, to achieve the following:

1. Measure variation in clinical decisions among practicing neurologists, specifically in how they detect, measure, and manage Alzheimer's disease in patients with symptoms and/or risk factors of cognitive decline. 2. Determine whether education on the Alzheimer's disease assay with accompanying test results leads to changes in clinical decision-making with regard to follow-up testing (e.g., CSF analysis, PET imaging), diagnostic accuracy, and treatment recommendations. 3. Model whether the use of the Alzheimer's disease assay leads to higher-value and/or lower-cost care decisions (including follow-up testing, diagnostics, and treatment) that can lead to more efficient care. 4. Determine whether the Alzheimer's disease assay results differentially impact treatment decisions for different patient types (use cases).
