Introduction

FHIR (Fast Healthcare Interoperability Resources) is the modern standard for storing and exchanging clinical data. But once your data is in a FHIR server, how do you actually explore it? FHIR data is stored as JSON — powerful, but not practical to read directly. I wanted a tool where you could click on a patient, see their conditions, medications, lab results, and more — in a clean, readable format. So I built the FHIR Patient Viewer.

How It Works

The app runs entirely in Docker and connects directly to an InterSystems IRIS for Health FHIR server.

In today’s healthcare data landscape, FHIR has become the standard for structured clinical data exchange. However, while FHIR excels at interoperability, its JSON format makes analytics challenging—including FHIR QuestionnaireResponse.

This project demonstrates how to transform FHIR QuestionnaireResponse data from nested JSON into relational SQL tables and vector embeddings. By integrating the InterSystems IRIS FHIR SQL Builder and Vector Search, we unlock the semantic meaning behind patient answers.
