Study of Development for RFID System to Hospital Environment.

Area of Science:

• Medical Informatics
• Ubiquitous Computing
• Healthcare Technology

Background:

• Electronic Medical Records (EMR) systems aim for anytime, anywhere access.
• Current systems face challenges in real-time patient tracking and data integration.
• Radio Frequency Identification (RFID) and Ubiquitous Sensor Network (USN) offer potential solutions.

Purpose of the Study:

• To develop and evaluate an RFID/USN-based information system for hospital environments.
• To enhance the functionality of Electronic Medical Records (EMR) by integrating real-time patient location and time data.
• To improve the efficiency of medical history taking and examinations.

Main Methods:

• A retrospective analysis of 235 RFID monitoring results was conducted.
• Data was collected from four ENT ambulatory clinics at Seoul National University Hospital.
• RFID tags were used to monitor patient "place" and "spending time" during medical examinations.

Main Results:

• RFID detection successfully represented patient location and examination duration.
• The system demonstrated the capability to integrate real-time spatial-temporal data into the EMR system.
• Analysis of RFID monitoring results provided insights into patient flow and examination times.

Conclusions:

• RFID/USN technology can effectively enhance hospital information systems.
• The developed system improves EMR by incorporating real-time patient movement and time data.
• This approach offers a pathway for more efficient and integrated healthcare information management.
