Interventions

  • Shared decision-making support tool — OTHER
    Based on previous data analysis, the decision-support tool is intended to facilitate discussions between the patients and their providers regarding the Phospho-Tau blood test. It functions as a flowchart to provide clear, accessible information about the blood test that will assist providers in discussions around guide the patients through navigating a diagnostic workups for memory problems.

Study Details

The goal of the current study is to evaluate a decision-support tool intended to help primary care providers (PCPs) communicate with patients about blood biomarker testing for Alzheimer's Disease, enhancing shared-decision making and information sharing in the clinical space. The main questions it aims to answer are: * Is the decision-support tool accepted and easy to use for PCPs? * Does using the tool improve shared decision-making during clinical encounters? Researchers will compare clinical encounters between PCPs who do not use the tool to discuss blood biomarker testing for Alzheimer's Disease, versus PCPs who have been trained to utilize the tool during clinical encounters to see whether the tool effectively facilitates shared-decision making.

Arms

  • Experimental: Simulation clinical encounters
    In Simulation 1, 15 PCPs will complete simulated clinical encounters with standardized patients after completing trainings on how to use the decision-support tool. In Simulation 2, a different group of 3-5 PCPs will see patients during simulated clinical encounters without using the decision-support too for the first half. In the second half, these PCPs will complete trainings on how to use the tool and then see the second half of the participants using the tool.

Primary Outcome Measure

Effectiveness of the tool on shared decision-making as measured by OPTION-5 Score [ Time Frame: This is a single time point outcome measure. In Simulation 2, providers participants will complete OPTION-5 immediately after they participate in the high fidelity clinical encounter session. ]
