Scalable patients tracking framework for mass casualty incidents
1Electrical and Computer Engineering Department, University of Massachusetts, Amherst, USA.
Summary
This study presents a low-cost system for tracking patients during mass casualty incidents (MCIs) using RFID triage tags and mobile anchors. The system achieves GPS-level accuracy without needing fixed infrastructure or GPS devices for every patient.
Area of Science:
- Biomedical Engineering
- Emergency Medicine
- Computer Science
Background:
- Effective patient tracking is crucial during mass casualty incidents (MCIs) for timely medical response.
- Existing tracking systems may be costly or require fixed infrastructure, limiting their deployment in dynamic disaster scenarios.
Purpose of the Study:
- To develop and evaluate a cost-effective patient tracking system for MCIs.
- To achieve accurate patient localization without fixed infrastructure.
Main Methods:
- Utilized active Radio Frequency Identification (RFID) triage tags for patients.
- Employed mobile anchor points (DM-tracks) carried by paramedics for real-time localization.
- System designed for no fixed deployment of localization devices.
Main Results:
- The RFID-based system demonstrated localization accuracy comparable to Global Positioning System (GPS) devices.
- The system maintained low cost for triage tags.
- No fixed infrastructure was required for the localization system.
Conclusions:
- The developed system offers a viable, low-cost solution for patient tracking in MCI settings.
- It provides accurate localization comparable to GPS without the associated high costs or infrastructure requirements.
- This technology can significantly improve patient management and resource allocation during mass casualty events.

01:18Steps in Outbreak Investigation
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
01:26Principles of Disease Surveillance
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
