“Triage with RFID Tags”, Proc. 1st International Conference on Pervasive Computing Technologies for Healthcare 2006, Dec. 2006. Koji Inoue

Triage: a procedure used by emergency personnel to ration limited medical resources to massive injured people

With triage tags◦ Classify and transport the injured effectively◦ Obtain and publish the state and the scale of the

casualty incident Speed up and increase the accuracy Verified through experiment

The work flow of triage operated by emergency personnel

First aid area, operation point 1st triage(incident site)

◦ Tagged in 30sec◦ Black/DECEASED◦ Red/IMMEDIATE◦ Yellow/DELAYED◦ Green/MINOR

2nd triage(first aid area)◦ Information of injured people◦ name/age/sex…◦ Written on tags

Hospital selection In ambulance, collect information

Data integrity◦ Triage tags are cut off, lost or left

Input throughput◦ Input information time should be very short

Availability◦ Input operations of injured-person's information

should be available anytime Low latency

◦ Information not collected until the ambulance which transported

Transport injured people as quickly as possible

Information collection of injured people affects to the latency of transportation◦ Troublesome operations for information collection◦ The level of injury and hospital to be transported

have to be collected within 1st or 2nd triage prior to transportation,

RFID as a local buffer◦ Can input data

Information can collect through wireless network

Easy to read by using mobile device compared to handwriting

A triage tags◦ With input forms for the information

1st and 2nd triage terminal, hospital selection◦ PDA RFID reader and a wireless communication

interface Ambulance terminal, hospital terminal,

Operation point terminal*◦ A notebook PC equipped with a handy RFID reader

and a wireless communication interface The server

A complex car crash of 5cars and about 82 injured people

Such a big scale!

The RFID triage system is demonstrated to be effective in mass casualty incidents of about 100 injured people

Using RFID to develope a information system
