In today's healthcare landscape, the rising costs of dedicated caretakers and the increasing demand for 24/7 patient monitoring present significant challenges. With average nursing costs ranging from $25-$40 per hour and the need for multiple shifts, healthcare facilities face annual expenses of $200,000+ per patient for continuous monitoring. This financial burden, combined with the global shortage of healthcare workers, creates an urgent need for innovative solutions.

The risk of unmonitored patient falls is particularly concerning:

• 700,000 to 1 million patients experience clinical harm due to in-hospital falls annually
• Over 1/3 of falls result in serious injuries (fractures, head trauma)
• 63% of serious fall injuries can lead to fatality
• Falls are among top 10 sentinel events in hospitals

CareBotix is an AI-powered patient monitoring system that combines computer vision, environmental sensing, and intelligent alerts to provide continuous, automated patient care. Our system reduces the need for constant human supervision while maintaining high standards of patient safety.

Our journey began during a healthcare hackathon where we witnessed the struggles of understaffed hospitals. The tragic stories of unmonitored patient falls and the overwhelming burden on nursing staff motivated us to create an automated solution.

1. Pose Detection Accuracy

   • Challenge: Initial YOLOv8 models had high false positives
   • Solution: Custom training with hospital-specific datasets
   • Result: Achieved 95% accuracy in fall detection

2. Real-time Processing

   • Challenge: High latency in video processing
   • Solution: Implemented parallel processing and GPU acceleration
   • Result: Reduced latency to <100ms

3. Environmental Monitoring

   • Challenge: Sensor noise and calibration issues
   • Solution: Implemented rolling average and calibration algorithms
   • Result: Achieved ±1% accuracy in readings

4. System Integration

   • Challenge: Coordinating multiple data streams
   • Solution: Developed event-driven architecture
   • Result: Seamless integration with <5ms overhead

• Hardware Components: $500-800 per unit
• Software License: $50/month per bed
• Installation: $200-300 per unit
• Annual Maintenance: $300 per unit

Total Cost of Ownership (First Year): ~$2,000 per bed Compared to traditional care: 90% cost reduction
