Walmart is a multinational superstore chain headquartered in Bentonville, Arkansas. Since its founding in 1962, Walmart has expanded to become a global leader in groceries and discount retail, serving around 280 million consumers per week. Its pharmacy division extends that reach into healthcare, with pharmacists helping patients manage their medications and chronic conditions.

Today, many patients track their health at home with blood pressure monitors, smart scales, and smartwatches. Pharmacists often lack access to these readings, or the time to identify long-term trends during brief patient visits.

Our Clinical Intelligence from Patient-Generated Health Data system bridges this gap by taking a patient’s home readings, visualizing them, and presenting talking points to the pharmacist.

Patients use our iOS application to choose which health readings to share with their pharmacist. These readings are collected in a secure manner from Apple Health through health and fitness tracker readings.

Pharmacists view this data and learn about patients through an intuitive web dashboard. This dashboard analyzes each patient’s data and gives talking points generated using artificial intelligence. The dashboard charts trends for each reading type and generates AI talking points for the pharmacist.

By interpreting and presenting trends through accessible visualizations and talking points, the system helps pharmacists provide more efficient and accurate care. Walmart pharmacists can now identify risks faster and better manage chronic conditions.

The pharmacist front end is implemented in React and TypeScript, and the iOS app is implemented in Swift. Our system’s back end is hosted on Google Cloud, with data storage in both FHIR server and PostgreSQL databases. We use a custom AI pipeline to generate talking points to present to the pharmacist.
