The Mayo Clinic in Rochester (Minnesota/USA) locates patients and staff in the emergency room with an RFID-based RTLS.
Each patient and staff member is individually identified by a bracelet or badge equipped with an RFID transponder. Each device in the emergency room is also tagged with an RFID label.
Each year, the Mayo Clinic treats more than 1.3 million patients from over 135 countries at four locations. Approximately 65,000 people are employed in the clinics.
The medical emergency center at the Rochester site has 73 rooms on a total area of 5,000 square meters. More than 190 patients are treated every day.
The manual assignment and short-term localization of patients, doctors, nursing staff and available rooms was a time-consuming and error-prone process.
To record all movements of patients and staff, more than 200 RFID readers with three to four external antennas each, were integrated into the ceiling construction of the building.
The distance between the installed readers is 1.8 to 2.4 meters - depending on the required precision of the localization.
Normally, the information that a person or a medical device is in a room is sufficient. In some special, more larger rooms it is essential to know whether a patient is on the left or right side of the room.
To protect privacy, no RFID hardware is installed in the washrooms. During the breaks, there is no tracking of employees outside the emergency clinic.
