Project Overview

This project provides a structured approach to diabetes risk assessment using OpenAI's language models. It processes patient data, generates risk assessments, and validates the output to ensure reliability and consistency.

Core Components

Diabetes Diagnosis Module

Located in diabetes_diagnosis.py, this module contains:

1. Assessment Model (Assessment class):

   • Defines the structure for risk assessments
   • Uses Pydantic for data validation
   • Enforces required fields and data types

2. Risk Assessment Function (get_risk):

   • Takes patient data as input
   • Communicates with OpenAI's API
   • Returns structured risk assessment

Validation System

1. Response Validation (validate_response):

   • Validates JSON structure
   • Ensures all required fields are present
   • Validates data types and constraints

2. Error Handling:

   • Catches and reports JSON parsing errors
   • Validates against the Assessment model
   • Provides clear error messages

Testing Framework

1. Test Types:

   • Unit tests for individual components
   • Integration tests for API interactions
   • Edge case testing

2. Mocking:

   • Uses pytest-mock for API call mocking
   • Prevents unnecessary API calls during testing
   • Ensures consistent test results

Tools and Dependencies

Core Dependencies

• Python 3.8+: Core programming language
• Pydantic: Data validation and settings management
• OpenAI Python Client: Interface with OpenAI's API
• python-dotenv: Environment variable management
• pytest: Testing framework

Development Tools

• pytest-mock: Mocking for tests
• pytest-html: HTML test reporting
• black: Code formatting
• flake8: Linting
• mypy: Static type checking

Workflow

1. Input Processing:

   • Patient data is collected and formatted
   • Data is validated for required fields

2. API Interaction:

   • Request is sent to OpenAI's API
   • Response is captured and parsed

3. Response Validation:

   • JSON structure is validated
   • Data types and constraints are checked
   • Results are formatted for output

4. Result Handling:

   • Valid results are processed
   • Errors are caught and reported
   • Logs are generated for debugging

Error Handling

The system implements robust error handling:

1. Input Validation:

   • Checks for required fields
   • Validates data types and formats
   • Provides clear error messages

2. API Error Handling:

   • Handles network issues
   • Manages API rate limits
   • Processes API-specific errors

3. Response Validation:

   • Validates JSON structure
   • Checks for required fields
   • Ensures data consistency

Extending the Project

Adding New Fields

To add new fields to the assessment model:

1. Update the Assessment class in diabetes_diagnosis.py
2. Add validation rules as needed
3. Update the test suite to cover new fields

Customizing Validation

To modify validation rules:

1. Edit the validate_response function
2. Add new validation rules to the Assessment class
3. Update tests to verify new validation rules

Adding Tests

To add new tests:

1. Create test cases in the tests/ directory
2. Use the existing test fixtures
3. Follow the pattern of existing tests
