AI-Assisted Fever Triage System

Inspiration

The inspiration for this project came from witnessing the overwhelming pressure on healthcare systems, particularly during flu seasons and health crises. Emergency rooms are often flooded with patients seeking guidance for fever-related symptoms, many of whom could receive initial assessment and care recommendations remotely.

We realized that while fever is one of the most common symptoms people experience, the decision of whether to seek immediate medical attention, wait it out at home, or take specific actions is often unclear to patients. This uncertainty leads to unnecessary ER visits for minor cases and delayed care for serious conditions.

Our goal was to bridge this gap by creating an AI-powered system that could provide immediate, reliable, and medically-sound triage assessments while maintaining the safety protocols that healthcare professionals follow.

💡 What it does

Our AI-Assisted Fever Triage System is a comprehensive healthcare application that:

Core Triage Functionality

Intelligent Symptom Assessment: Collects detailed patient information including temperature, duration, accompanying symptoms, and medical history
AI-Powered Analysis: Uses advanced language models (Google Gemini) trained on medical protocols to assess symptom severity
SIRS Criteria Integration: Implements Systemic Inflammatory Response Syndrome criteria for accurate medical assessment
Risk Stratification: Categorizes patients into immediate emergency, urgent care, or home care recommendations

Advanced Features

User Profiling System: 4-step comprehensive health profile including medical conditions, allergies, medications, and emergency contacts
Temperature Tracking: Daily temperature logging with visual charts and trend analysis
Smart Medicine Reminders: Customizable medication schedules with browser notifications
AI Chatbot: Follow-up care guidance, symptom monitoring, and 24/7 health support
Demo Cases: Educational scenarios showing system capabilities and decision-making process

Emergency Protocols

Immediate Alert System: Detects high-risk symptoms requiring immediate medical attention
Clear Action Plans: Provides specific, actionable recommendations based on assessment results
Professional UI: Medical-grade interface designed for clarity and trust in healthcare decisions

🛠️ How we built it

Architecture Overview

We designed a modern, scalable full-stack application with clear separation of concerns:

Frontend: Next.js 14 with TypeScript and Tailwind CSS Backend: FastAPI with Python AI Integration: Multi-provider architecture supporting Google Gemini, OpenAI, and others Deployment: Vercel (frontend) + Render (backend)

Technical Implementation

Backend Development (FastAPI)

# Core triage assessment endpoint
@app.post("/assess-symptoms")
async def assess_symptoms(request: TriageRequest):
    # Implement SIRS criteria and medical protocols
    # Multi-provider AI integration with intelligent fallback
    # Structured medical assessment with severity scoring

Key Backend Features:

RESTful API design with comprehensive error handling
Multi-provider AI architecture for reliability
Medical protocol integration (SIRS criteria)
Rate limiting and security measures
Health check endpoints for monitoring

Frontend Development (Next.js)

Component Architecture:

SymptomForm.tsx: Comprehensive symptom collection with validation
ResultsDisplay.tsx: Clear, color-coded triage results
UserProfile.tsx: Multi-step health profile management
TemperatureTracker.tsx: Interactive temperature logging
MedicineReminder.tsx: Smart notification system
Chatbot.tsx: AI-powered follow-up care

State Management:

React hooks for local state
localStorage for user data persistence
Real-time updates and responsive design

Prompt Engineering:

Medical-specific prompts with clinical protocols
Structured response formats for consistency
Safety-first approach with conservative recommendations

Development Workflow

Requirements Analysis: Researched medical triage protocols and emergency criteria
Architecture Design: Planned scalable, maintainable system structure
Backend Implementation: Built robust API with medical protocol integration
Frontend Development: Created intuitive, professional healthcare UI
AI Integration: Implemented multi-provider system for reliability
Testing & Refinement: Tested with various medical scenarios
Deployment Configuration: Set up production-ready hosting

Challenges we ran into

Technical Challenges

1. AI Provider Reliability

Problem: Initial implementation used only OpenAI, which hit quota limits during development

Error 429: You exceeded your current quota

Solution: Built multi-provider AI architecture with intelligent fallback system

Google Gemini as primary provider
OpenAI, Hugging Face, and Ollama as backups
Dynamic provider testing and selection

2. Medical Protocol Integration

Problem: Ensuring AI responses align with actual medical triage protocols Solution:

Integrated SIRS (Systemic Inflammatory Response Syndrome) criteria
Structured prompts with medical decision trees
Conservative approach prioritizing patient safety

3. Model Configuration Issues

Problem: API errors due to incorrect model names and endpoints

Error 404: Model gemini-2.0-flash-thinking-exp not found

Solution:

Implemented dynamic model testing
Created fallback model hierarchy
Added comprehensive error handling

4. Professional UI Standards

Problem: Initial UI had excessive emojis and casual appearance inappropriate for healthcare Solution: Complete UI overhaul with medical-grade design principles

Removed all emojis and casual elements
Implemented professional color schemes
Added clear, clinical typography

Development Process Challenges

5. SSL Certificate Issues

Problem: Development environment SSL verification failures Solution: Implemented conditional SSL verification with secure production settings

6. State Management Complexity

Problem: Managing complex user profiles, temperature data, and medicine schedules Solution: Created modular state management with local Storage persistence
