One of the many important scientific breakthroughs of late is the use of radio frequencies in identification, commonly known as RFID. First developed to supplant the outdated bar codes, RFID went further while used as a transportable ID system. Today, there is now the RFID patient tracking Australia.
This tracking system using RFID is mostly used on patients who are undergoing medical treatments but can be ambulant and are not usually in their designated places (beds/rooms). These are also used on babies for correct identification purposes. This hospital RFID is usually embedded on wristbands with unique UHF frequencies but is harmless to the patient-wearer. With the device, doctors and the hospital staff can easily locate their patients. There are also fewer incidences now of identification errors on patients, especially the babies. Benefits These RFID tracking devices are important to the hospital authorities because some high-end systems used nowadays have the patient’s personal and medical data integrated into the tracking device. This includes such items as EMR, schedules, lab tests, etc. for easy, fast and automatic referencing. The technology actually reduces the time spent on searching for the patients and implementing other needed things with the use of the RFID patient tracking. The integration of the data into the tracking system is carried through the hospital’s healthcare systems integration. RTLS The RTLS (real-time location systems) for health care environment have been integrated into the technology together with the enterprise health record (HER) of hospitals. This is to improve the patient’s safety, especially in the emergency department. When the patient is admitted to the emergency department (ED), he/she is immediately registered and issued an RFID. The RTLS also records the patient’s interaction with doctors and hospital staff (who have their own identification tags). Whenever there is patient movement, the RFID tracks it down and sends out real-time updates to the system. The patient’s information will provide the basis for historical analytics for follow-through improvement or medical action. The automatic capability of the system provides the right timing for the medical authorities to make real-time adjustments and other decisions. Some details With the patient’s RFID worn as a wrist band, tracking and locating are easily done within the hospital’s premises. The bands send out signals that are instantly read and interpreted by RFID readers strategically distributed all over the facility. These tag readers placed in specific areas can locate a patient within a measurable distance (10 feet away or a thousand feet). This is defined by the system to cover an area that is cost-effective in terms of the numbers of tag readers needed. Positioning The patient’s location is sorted out by an integrated software from the supplied data from the readers. It will determine the location of the tag (and the patient) via the positioning algorithms based on the strength of the signal from the tags as read out by the readers nearby. Alerts are also specially programmed into the tracking system based on the needs of the facility and the gravity of most situations. More innovations are still being worked out to improve the RFID patient tracking system.
