Stripped of its media hype, RFID is essentially a tracking device. One might wonder what the big deal is. With the never-ending effort of improving patient safety and cutting costs, health care is certainly well-aware of the need to track its every activity. In an industry mandated by federal, state, county and local regulations, tracking is nothing new.
And yet, RFID offers a powerful benefit over other tracking technologies such as bar coding or manual processes. RFID can automatically trace any medical device, pharmaceutical or patient over a given period of time.
Because RFID tags have reading and writing capability, as well as sensors, an RFID-equipped medicine or surgical instrument can indicate in real-time whether the item has been introduced to contaminants, when and where it has moved over time, and environmental conditions, such as temperature and humidity.
