1. 1. Define Your Patient Onboarding Workflow

   Start by mapping the key stages in your patient onboarding process. A typical AI-powered workflow includes:

   • Patient submits intake form (web/mobile)
   • AI extracts and validates data (name, DOB, insurance, symptoms, etc.)
   • Eligibility check via payer API
   • Document upload and OCR (ID, insurance card)
   • Automated EHR record creation
   • Patient receives confirmation and next steps

   Tip: Document your workflow as a flowchart or JSON/YAML spec. This guides your API and data model design.

   
   steps:
     - name: intake_form
       type: form
     - name: data_extraction
       type: ai_llm
     - name: eligibility_check
       type: api_call
     - name: document_ocr
       type: ai_ocr
     - name: ehr_record
       type: db_write
     - name: notify_patient
       type: email
     

2. 2. Scaffold Your Backend: FastAPI + Celery + PostgreSQL

   Set up a modular backend to orchestrate your workflow. We'll use FastAPI for the API, Celery for async tasks, and PostgreSQL for data storage.

   1. Clone your starter repo or initialize a new project:

      $ mkdir ai-patient-onboarding
      $ cd ai-patient-onboarding
      $ python3 -m venv .venv
      $ source .venv/bin/activate
      $ pip install fastapi[all] celery[redis] psycopg2-binary sqlalchemy pydantic
            

   2. Dockerize PostgreSQL and Redis for local development:

      
      version: "3"
      services:
        db:
          image: postgres:15
          restart: always
          environment:
            POSTGRES_USER: onboarding
            POSTGRES_PASSWORD: onboardingpass
            POSTGRES_DB: onboardingdb
          ports:
            - "5432:5432"
        redis:
          image: redis:7
          restart: always
          ports:
            - "6379:6379"
            

      $ docker compose up -d
            

   3. Initialize your FastAPI app:

      
      
      from fastapi import FastAPI
      from app.routers import onboarding
      
      app = FastAPI(title="AI Patient Onboarding API")
      app.include_router(onboarding.router, prefix="/onboarding")
            

   4. Set up Celery for background task orchestration:

      
      
      from celery import Celery
      
      celery_app = Celery(
          "onboarding_tasks",
          broker="redis://localhost:6379/0",
          backend="redis://localhost:6379/0"
      )
            

   5. Run your API and worker (in two terminals):

      $ uvicorn app.main:app --reload
      $ celery -A app.celery_worker.celery_app worker --loglevel=info

3. 3. Build the Intake Form and API Endpoint

   Create a web form for patients to submit their information. For this tutorial, we'll focus on the backend API endpoint.

   
   
   from fastapi import APIRouter, BackgroundTasks
   from pydantic import BaseModel
   
   router = APIRouter()
   
   class IntakeForm(BaseModel):
       name: str
       dob: str
       insurance_number: str
       symptoms: str
   
   @router.post("/intake")
   async def intake(form: IntakeForm, background_tasks: BackgroundTasks):
       # Save to DB (pseudo-code)
       # db.save(form.dict())
       # Trigger AI extraction in background
       background_tasks.add_task(process_intake, form.dict())
       return {"status": "received"}
     

   Screenshot description: API testing tool (e.g., Postman) sending a POST request to /onboarding/intake with sample patient data JSON, receiving {"status": "received"} response.

4. 4. Integrate AI Data Extraction (LLM + OCR)

   Use a large language model (LLM) to extract and validate structured data from free-text fields or uploaded documents. Combine with OCR for ID/insurance cards.

   1. Install OpenAI SDK:

      $ pip install openai
            

   2. Configure your AI extraction task:

      
      
      import openai
      
      def extract_patient_data(text: str) -> dict:
          prompt = (
              "Extract the following fields from the text: Name, DOB, Insurance Number, Symptoms. "
              "Return as JSON."
          )
          response = openai.ChatCompletion.create(
              model="gpt-4o",  # Or your preferred LLM
              messages=[
                  {"role": "system", "content": prompt},
                  {"role": "user", "content": text}
              ]
          )
          return response.choices[0].message.content
            

   3. Integrate OCR for document uploads (optional):

      $ pip install pytesseract pillow
            

      
      import pytesseract
      from PIL import Image
      
      def extract_text_from_image(image_path: str) -> str:
          img = Image.open(image_path)
          return pytesseract.image_to_string(img)
            

   4. Connect extraction to your workflow task:

      
      
      from app.ai.extraction import extract_patient_data
      
      def process_intake(form_data):
          # Extract structured data with LLM
          patient_info = extract_patient_data(form_data["symptoms"])
          # Save to DB, trigger eligibility, etc.
            

   Screenshot description: Terminal output showing extracted JSON fields from a sample patient intake submission.

5. 5. Automate Eligibility Checks via Payer API

   Next, automate insurance eligibility verification by integrating with payer APIs (e.g., Change Healthcare, Availity, or mock APIs for dev/testing).

   1. Example: Call mock eligibility API

      
      import requests
      
      def check_eligibility(insurance_number):
          response = requests.post(
              "https://mock-payer-api.com/eligibility",
              json={"insurance_number": insurance_number}
          )
          return response.json()
            

   2. Integrate with your workflow:

      
      def process_intake(form_data):
          # ...previous steps...
          eligibility = check_eligibility(form_data["insurance_number"])
          # Save eligibility status to DB
            

   Screenshot description: API response in JSON showing eligibility status: {"eligible": true, "plan": "PPO 2026"}

6. 6. Store Records Securely and Audit Trail

   Use SQLAlchemy to model and persist patient onboarding data, including an audit trail for compliance.

   
   
   from sqlalchemy import Column, Integer, String, DateTime
   from sqlalchemy.ext.declarative import declarative_base
   from datetime import datetime
   
   Base = declarative_base()
   
   class OnboardingRecord(Base):
       __tablename__ = "onboarding"
       id = Column(Integer, primary_key=True)
       name = Column(String)
       dob = Column(String)
       insurance_number = Column(String)
       symptoms = Column(String)
       eligibility_status = Column(String)
       created_at = Column(DateTime, default=datetime.utcnow)
       updated_at = Column(DateTime, default=datetime.utcnow, onupdate=datetime.utcnow)
     

   Tip: Always encrypt sensitive fields at rest and enable row-level auditing for regulatory compliance.

7. 7. Notify Patients and Trigger Next Steps

   Send automated emails or SMS to confirm onboarding and provide next steps.

   
   import smtplib
   from email.mime.text import MIMEText
   
   def send_confirmation_email(email, name):
       msg = MIMEText(f"Hello {name}, your onboarding is complete. Next steps: ...")
       msg["Subject"] = "Onboarding Confirmation"
       msg["From"] = "noreply@yourclinic.com"
       msg["To"] = email
   
       with smtplib.SMTP("smtp.mailtrap.io", 2525) as server:
           server.login("your_user", "your_pass")
           server.send_message(msg)
     

   Screenshot description: Email inbox with "Onboarding Confirmation" message and next steps.

8. 8. Secure Your API and Ensure Compliance

   Protect all endpoints with OAuth2 or JWT authentication. Always use HTTPS in production and audit all access.

   
   from fastapi.security import OAuth2PasswordBearer
   
   oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")
   
   @app.get("/secure-data")
   async def secure_data(token: str = Depends(oauth2_scheme)):
       # Validate token, check permissions
       return {"data": "secure"}
     

   Tip: Use environment variables for all API keys and secrets. Regularly review audit logs.

9. 9. Test the Full Workflow End-to-End

   Use pytest and httpx to automate scenario testing.

   $ pip install pytest httpx
     

   
   
   import httpx
   
   def test_intake_flow():
       data = {
           "name": "Jane Doe",
           "dob": "1990-01-01",
           "insurance_number": "ABC123456",
           "symptoms": "Headache and fatigue"
       }
       r = httpx.post("http://localhost:8000/onboarding/intake", json=data)
       assert r.status_code == 200
       assert r.json()["status"] == "received"

Common Issues & Troubleshooting

• Celery tasks not running: Ensure your Redis container is up and celery -A app.celery_worker.celery_app worker is running.
• OpenAI API errors: Double-check API keys, model names, and rate limits. Test with openai --version and openai api models.list.
• Database connection refused: Confirm PostgreSQL is running and credentials in your SQLAlchemy config match docker-compose.yml.
• HTTPS/SSL errors: For local dev, use ngrok to tunnel your API (ngrok http 8000).
• Data privacy compliance: Mask PHI in logs and error traces. Regularly review data retention policies.
