MediCall

An AI-powered Emergency Room Matching System connecting paramedics to the nearest available hospital in seconds.

🚨 The Problem: Critical Minutes Lost During Emergencies

During medical emergencies, every second counts. The "golden hour" - the critical time window immediately following a traumatic injury - is essential for patient survival. However, this precious time is often wasted when:

• Paramedics must manually call multiple hospitals to find an available emergency room
• Emergency Medical Technicians (EMTs) spend valuable minutes on administrative tasks instead of patient care
• Hospital selection is based on incomplete information, leading to inefficient patient routing
• Communication delays between ambulances and hospiatals create unnecessary wait times

These inefficiencies can mean the difference between life and death for critically injured patients.

💡 Our Solution: MediCall

MediCall revolutionizes emergency response by creating a direct, AI-powered connection between paramedics and available emergency rooms. The system:

• Allows paramedics to quickly input patient condition and location data
• Uses Gemini AI to analyze patient information and identify suitable hospitals
• Automatically contacts multiple hospitals simultaneously using Twilio API
• Collects real-time availability data through automated voice response systems
• Recommends the optimal hospital based on availability, proximity, and compatibility with the patient's condition
• Provides turn-by-turn navigation guidance to the selected facility

The result: Hospital matching in under 1 minute, 5x faster than traditional methods, with 100% secure patient data handling.

🛠️ Key Features

• Chat-based Interface: Quickly enter patient condition and location
• Gemini AI: Analyzes patient information, recommends suitable hospitals
• Twilio API: Parallel automated hospital calls IVR (1: Accept / 2: Reject via dial-tone)
• TTS (Text-to-Speech): Delivers automated voice messages to hospitals
• Mapbox Navigation: Provides accurate, real-time route guidance
• Material Design: Intuitive UI aligned with Google's Material Design
• EMT Verification: Exclusive secure access for verified paramedics

Differentiation from Existing Solutions

• Traditional methods rely heavily on manual phone calls or centralized emergency medical centers to verify hospital availability, leading to significant delays
• MediCall uniquely integrates Gemini AI and IVR API to automatically and simultaneously contact multiple hospitals, collect real-time responses, and instantly recommend the optimal hospital
• This greatly reduces the administrative workload for paramedics and helps preserve the critical golden hour for patients
