Automate Your Healthcare: Building an AI Agent to Book Doctor Appointments and Archive Lab Reports

A developer built an AI agent using GPT-4o, the Browser-use library, and Playwright to automate healthcare tasks such as booking doctor appointments and downloading lab reports. The agent visually navigates complex web portals, handling logins and downloads, and can integrate with a RAG system for querying medical records.

We've all been there: staring at a clunky, 10-year-old hospital web portal, clicking through endless nested menus just to book a simple check-up or download a PDF lab result. It's tedious, error-prone, and frankly, a waste of human potential. But what if you could just tell an AI, "Book me a dermatologist for next Tuesday and save my blood test results to my health folder," and it just... did it? In this tutorial, we are diving deep into the world of autonomous agents , GPT-4o , and LLM-driven web navigation . By leveraging the revolutionary Browser-use library and Playwright , we’ll build a vision-capable agent that can navigate complex UIs, handle logins, and automate the most frustrating parts of healthcare administration. 🚀 Traditional automation tools like Selenium or Puppeteer rely on brittle DOM selectors button-id-342 . When a hospital updates its website, your script breaks. Using Browser-use with GPT-4o changes the game. Instead of looking for code, the agent sees the page like a human, understanding that a magnifying glass icon means "Search" regardless of the underlying HTML. The system logic involves a feedback loop where the LLM perceives the browser state screenshot + DOM tree , decides on an action, and executes it via Playwright. php graph TD A User Goal: Book Appointment/Download Report -- B LangChain Agent / Browser-use B -- C{Decision Engine: GPT-4o} C -- D Action: Click/Type/Scroll D -- E Playwright Browser Instance E -- F Hospital Portal UI F -- G Visual & HTML Feedback G -- C F -- H Download Lab Report PDF H -- I Structured Storage / RAG Pipeline I -- J Task Completed ✅ Before we start, ensure you have the following in your tech stack: pip install browser-use playwright langchain-openai playwright install The core of our solution is the Agent class from the browser-use library. It wraps the browser interactions into a "thought-action" loop. python from browser use import Agent from langchain openai import ChatOpenAI import asyncio async def run healthcare agent : Initialize our LLM GPT-4o is highly recommended for visual UI tasks llm = ChatOpenAI model="gpt-4o" Define the mission task = "1. Go to 'https://portal.city-hospital.com' and login. " "2. Navigate to the 'My Appointments' section. " "3. Find the first available slot for 'General Practitioner' next week. " "4. Then, go to 'Lab Results', find the latest PDF, and download it." agent = Agent task=task, llm=llm, history = await agent.run print history -1 .result if name == " main ": asyncio.run run healthcare agent Healthcare portals often use complex authentication. The magic of Browser-use is that it can "read" the screen. If it encounters a captcha, it can notify the user or use vision-to-text to solve simple ones. For handling files, we can extend the agent's controller to ensure downloads are routed to a specific directory for our RAG Retrieval-Augmented Generation system. python from browser use import Agent, BrowserConfig from browser use.browser.context import BrowserContextConfig Configure the browser to handle downloads automatically config = BrowserConfig headless=False, Set to True in production disable security=True, extra chromium args= "--disable-web-security" Custom context to define where our PDF goes context config = BrowserContextConfig save downloads path="./medical records raw" agent = Agent task="Navigate to the health portal and download the March 2024 Lab Report.", llm=ChatOpenAI model="gpt-4o" , browser config=config, browser context config=context config Once the agent downloads the lab report, it’s just a "dumb" PDF. To make it useful, we process it into a vector database. This allows you to ask questions like, "Are my iron levels trending upwards compared to last year?" While this tutorial focuses on the retrieval the agent , the processing is where things get truly sophisticated. Building a prototype is easy, but making a production-ready agent that handles edge cases—like session timeouts, dynamic pop-ups, and multi-factor authentication—requires a more robust architectural pattern. For advanced implementation patterns on scaling these autonomous workflows and integrating them with secure healthcare data pipelines, I highly recommend checking out the technical deep-dives at WellAlly Tech Blog . They cover great production-grade examples of how to wrap these agents in FastAPI and secure them for enterprise use. We are moving away from an era where we adapt to software, and into an era where software adapts to us. By combining GPT-4o’s vision with Browser-use , we’ve effectively given our AI a pair of eyes and a mouse. Next Steps: What are you planning to automate next? The DMV? Your tax portal?
