HIX Physician Conversational Agent
Engineered an advanced diagnostic copilot for Health Information Exchange (HIX) networks. Built on Google Dialogflow CX and robust Node.js middleware, the agent instantly retrieves complex patient histories.
The Challenge
Physicians navigating Health Information Exchange (HIX) systems face cumbersome interfaces that require multiple clicks, screen changes, and manual searches to access critical diagnostic data. In time-sensitive clinical environments, these friction points directly impact patient outcomes.
The goal was to create a natural language interface that allows physicians to query HIX data as naturally as speaking to a colleague — "What were the last three lab results for patient 12847?" — and receive instant, structured responses.
The Solution
I built a conversational agent using Google Dialogflow CX and Node.js with custom pipelines that parse physician queries into structured HIX API calls. The system maintains conversation context, handles ambiguous references, and presents results in a clinically optimized format.
The agent integrates directly with existing HIX APIs, transforming complex multi-system queries into single natural language requests. Developed utilizing Agent Studio, it supports voice input for hands-free operation during patient examinations and procedures.
