The newborn’s EMR contains all the vital statistics recorded after birth and throughout his or her nursing history. Figure 2 shows a medical professional scanning the baby’s RFID bracelet using the PDA device. Each time the baby is bathed, for example, the caregiver scans the baby’s RFID tag and the system registers that action as an event. The event is automatically logged in the EMR. Figure 3 shows a sample EMR, with some of the data available to caregivers.
Figure 3 shows the types of information stored in the basic neonatal record for each newborn.
Figure 4 shows a sample record of neonatal care activities, such as temperatures during the day and feeding information.

Details on System Setup
Here are the technical details of the system piloted at WonJu Hospital. Figure 5, on the next page, shows the overall system setup.
The unique identification number that is applied to the infant’s RFID bracelet is generated automatically from the mother’s master health record, from a server running on Intel® architecture.
The infant’s information, including such details as bath times and medical vital statistics, is recorded into an SQL database.
The server is attached to ECO’s short-read range and middle-read range RFID readers, which are responsible for programming and detecting the tags with the unique serial numbers.
The server is linked to ECO’s kiosk outside the neonatal care unit via a standard hospital Ethernet network.
The medical staff uses PDAs based on Intel Mobile Media Technology, which are fitted with CF-type RFID readers.
The PDAs are set up to communicate wirelessly with a local Wi-Fi* network, which then relays the information back to the main server via the hospital’s Ethernet network.
Tags are passive, 1024-bit, and operate on an ISO 15693- compliant 13.56 MHz frequency, with a maximum range of 50 cm with a middle-read range RFID reader. The 13.56 MHz frequency is an international medical and scientific standard, so the system can be used anywhere in the world.
