Care-Glide is a geo-location aware emergency response system designed to assist senior citizens living alone by instantly connecting them with the nearest available nurse.
Built using the MERN stack and AWS services, the system ensures fast, reliable, and intelligent nurse allocation during emergencies.
Patients (especially senior citizens) living alone may face emergencies such as:
- Sudden health deterioration
- Falls or accidents
- Urgent medical needs
In such situations, immediate assistance is critical.
Care-Glide solves this by:
- Identifying the nearest nurse in real-time
- Calculating fastest route using geo-data
- Automatically notifying nurses until one accepts
- One-click emergency alert trigger
- Automatic location detection (GPS)
- Real-time tracking of assigned nurse
- Emergency status updates
- Live location tracking
- Receive emergency alerts
- Accept / reject requests
- Route navigation to patient
- Finds nearest nurse using geo-coordinates
- Calculates fastest route (not just distance)
- Prioritizes based on:
- Distance
- Travel time
- Availability
- Auto-escalation if nurse doesn't respond
- React.js
- Tailwind CSS / CSS
- Axios
- Google Maps API / Mapbox
- Node.js
- Express.js
- MongoDB (Mongoose)
- REST APIs
- AWS EC2 (Backend hosting)
- AWS S3 (Media / assets storage)
- AWS Lambda (Optional async processing)
- AWS API Gateway
- AWS SNS / Firebase (Push Notifications)
- WebSockets / Socket.IO
- Geolocation APIs
- Haversine formula / routing APIs

- Patient triggers emergency alert
- System fetches:
- Patient location
- List of available nurses
- Calculates nearest nurse using:
- Geo-distance
- Estimated travel time
- Sends notification to closest nurse
- If no response:
- Escalates to next nearest nurse
- Once accepted:
- Nurse is assigned
- Navigation begins
We use a combination of:
- Haversine Formula → for distance calculation
- Routing APIs (Google Maps) → for travel time
- Priority Queue → to rank nurses
- Secure APIs with authentication (JWT)
- Encrypted data transmission (HTTPS)
- Role-based access (Patient / Nurse / Admin)
- Location data used only during active requests
