Clinical Trial Summary

The eRADAR Brain Health Study seeks to refine and test a novel, low-cost strategy for increasing dementia detection within primary care.

Description:

Detailed description: eRADAR stands for "electronic health record (EHR) Risk of Alzheimer's and Dementia Assessment Rule." It is a low-cost tool or algorithm that uses readily available EHR data elements to identify high-risk patients. The investigators will conduct a pragmatic randomized controlled trial to assess the impact of implementing eRADAR as part of a supported outreach process on dementia detection rates. The investigators will also explore the impact of eRADAR implementation on healthcare utilization and patient experience.

Intervention

Other:
• Brain Health Assessment
Research interventionists, who will be trained and licensed health practitioners (e.g., social workers), will ask participants about changes in memory or thinking and daily function, screen for depression, and administer a standard cognitive screening test. Research interventionalists will use a standardized note template to document results in the participant's EHR. Research interventionists will notify participants and PCPs if follow-up is recommended.
