Inspiration

The project was inspired by the critical gaps in healthcare access in rural African communities, especially in our country, Malawi, particularly for pregnant women, elderly patients, and chronic disease sufferers. Limited access to clinics, diagnostics and emergency care motivated the creation of a unified platform integrating AI, IoT and mobile technologies to improve monitoring and response. According to WHO (2023), nearly 80% of sub-Saharan Africa faces a shortage of healthcare specialists, and UNICEF (2022) reports that only 44% of Malawian households have access to a clinic within 5 km, highlighting the urgent need for innovative healthcare solutions such as this.

What It Does

HealthBridge AI is a unified smart community health platform that:

Monitors patient vitals in real-time via IoT devices
Geo-Location & Distance Calculation: Redirect patient to nearest active hospital.
Analyzes medical images like X-rays and ultrasound using AI
Sends medication reminders and tracks adherence
Provides AI-assisted symptom checking and risk prediction
Generates emergency alerts and redirects patients to the nearest active clinics
Supports doctors and clinics with clinical decision support insights

How We Built It

System Architecture: Modular architecture separating IoT data collection, AI analytics, backend APIs, and frontend dashboards
IoT Integration: Wearable and home-based sensors for heart rate, blood pressure, temperature, oxygen level, and optional glucose monitoring
AI Engine: CNNs for X-ray analysis, LSTMs for time-series vitals prediction, and classification models for risk assessment
Backend Development: Node.js + Express APIs handling sensor data, FastAPI(ML) for AI predictions, USSD for feature phones, and emergency routing logic
Frontend Development: Responsive dashboards and mobile-friendly apps using Next.js and TailwindCSS
Emergency Handling: GPS-based redirection algorithm integrated with SMS and app notifications for clinics, patients, and caregivers.

Challenges We Ran Into

Real time processing of IoT data and timely alerts
AI model training with limited and imbalanced medical datasets
Designing an emergency routing algorithm factoring distance, clinic capacity and service suitability
Integrating multiple modules (IoT, AI, database, frontend) seamlessly
Ensuring accessibility and usability for users with varying digital literacy levels

Accomplishments That We're Proud Of
