🏥 WaitlessOS – Your AI-Powered Healthcare Companion

💡 Inspiration As an international students, we often hesitated to visit a clinic or hospital in Canada. Unlike permanent residents with OHIP, we have UHIP or private plans that aren’t accepted everywhere, and coverage varies greatly. we constantly asking:

“Will they accept my insurance?”

“How much will I need to pay?”

“Where is the nearest clinic that fits my situation?”

“Should I go to the ER, urgent care, or just wait?”

This overwhelming uncertainty inspired the creation of WaitlessOS — an AI-powered platform that bridges the gap between patients, healthcare providers, and insurance systems in one seamless experience.

🎯 Purpose

WaitlessOS helps patients — especially newcomers, students, and visitors — make informed decisions about where, when, and how to seek care by:

Classifying the urgency of symptoms using AI triage

Showing the most relevant clinics/hospitals based on insurance, proximity, and availability

Providing cost estimates and insurance coverage breakdowns

Enabling instant booking, waitlist joining, and navigation

Reducing decision friction, panic, and time wasted in emergencies

⚙️ Functionality

Intelligent Triage

Users enter their symptoms and WaitlessOS:

Uses Gemini AI API to assess urgency

Suggests whether to go to ER, urgent care, or book a clinic

Smart Search

Filters clinics by insurance (e.g., UHIP, Blue Cross, Aetna)

Ranks based on distance, ratings, and availability

Supports real-time appointment visibility (with potential for API integration)

Coverage & Cost Estimator

Explains what your insurance covers

Estimates out-of-pocket cost based on appointment type and plan

Seamless Booking

Book appointments or join waitlists directly in-app

Integrates with Google Maps for directions and static maps

🛠️ Tech Stack

Frontend: React, TailwindCSS, Vite
Backend: Node.js, Express, TypeScript, MongoDB, Redis
Google Maps API for geolocation and navigation
Gemini (Generative AI) for symptom triage
Authentication: JWT

📈 Impact

WaitlessOS has the potential to:

Empower patients with clarity and control over their healthcare journey
Reduce emergency room overcrowding by routing users appropriately
Improve access for underrepresented groups like international students
Streamline communication between clinics and patients
If integrated with real healthcare APIs and patient records (with HIPAA compliance), it can evolve into a full-service telehealth system.

📚 What We Learned

Technical Skills

Handling secure, environment-based config loading (dotenv, .env)
Using TypeScript for cleaner, safer backend logic
Managing asynchronous logic across multiple services (MongoDB, Redis, Gemini)
Implementing real-world rate limiting, logging, and error handling

Personal Growth

Navigating healthcare complexity
Learning how insurance systems vary across user groups
Developing a user-centric mindset for accessibility and urgency

🔥Challenges Faced

Sensitive APIs: Some healthcare APIs require real authorization (e.g., Epic, Cerner) — hard to simulate in a hackathon setting.
AI hallucination: Gemini sometimes gave vague triage results, so post-processing was needed.
Map APIs: Managing markers, distance matrix, and fallback options in case of missing API keys
Time limits: Building a full-stack app with AI integration in limited time required extreme prioritization
