This is a national-level research study of neurologists and dementia specialists. The purpose of this study is to assess the clinical evaluation and management recommendations made by practicing providers for patient simulations with symptoms of cognitive decline.
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).

Between Round 1 and Round 2 virtual patient case administration, Intervention participants will receive educational materials describing the clinical validation and use cases of the Alzheimer's disease assay. These materials will approximate the type of information physicians would receive to introduce them to the Alzheimer's disease assay and may be comprised of a slide deck, fact sheet, sample test report, and/or example case scenarios.
Within each of their virtual patient cases in Round 2 of case administration, Intervention participants will receive Alzheimer's disease assay results at the clinically appropriate point for each case.

QURE virtual patient clinical score difference
Difference-in-differences regression analysis between the control and the intervention groups' diagnosis and treatment of symptoms of cognitive decline, as measured by the participants' diagnostic and treatment case scores. In each QURE case, every participants' care recommendations are evaluated against evidence-based care scoring criteria, which can range from 0% to 100% (with higher percentages indicating better outcomes).
Time frame: Up to 12 months
Change in follow-up decisions (QURE scored-based) after receiving AD assay results
Assessing changes in follow-up decisions (via QURE case domain scores) among intervention providers after they receive the results of the novel AD assay in the second round of case administration. In each QURE case, every participants' care recommendations are evaluated against evidence-based care scoring criteria, which can range from 0% to 100% (with higher percentages indicating better outcomes).
Time frame: Up to 12 months
Variation in QURE virtual patient case baseline scores
Participants completing QURE virtual patients receive scores based upon the quality of care they provide. In each QURE case, every participants' care recommendations are evaluated against evidence-based care scoring criteria, which can range from 0% to 100% (with higher percentages indicating better outcomes). This measure will assess the baseline levels of variation in the care of virtual patients with symptoms of cognitive decline among all participants, including by use case types.
Time frame: Up to 12 months
Difference in QURE virtual patient case scores by case type
Difference in the overall quality scores between control and intervention participants. The overall score is calculated as the percent of correct (evidence-based) minus incorrect (low-value) decisions divided by the total number of correct decisions in a QURE virtual patient case. Differences in scores between case types across rounds will be assessed to determine which use cases show the most improvement.
