Abstract

An RFID system has been widely applied in many areas over the initial SCM application. In the literature enormous RFID applications in healthcare are documented to improve patient safety, patient/provider logistics, and the efficiency of collecting data. Based on the proposed 4-layered RFID system architecture, we introduce a case that implemented an UHF passive RFID-based tracking system in an outpatient clinic. Particularly, we propose a method to process RFID data that contains noise and missing reads. The proposed method for processing unreliable RFID data is capable to locate the tag accurately and provide additional business information. We finally conclude the paper with identifying obstacles and what is necessary to ensure system reliability.

RFID 시스템은 초기 공급사슬관리 영역에서 다양한 영역으로 확산되고 있다. 의료분야 또한 환자, 의료진, 의료기기 등의 위치추적 관리 의약품 추적관리 등의 영역에 RFID 시스템 도입을 진행하고 있다. 본 연구는 외래병원에서 태그의 위치추적을 위한 수동형 RFID 기술기반의 시스템 구축 사례를 4계층의 시스템 구조를 활용하여 분석하였다. 특히 일반적으로 수동형 RFID 기술에서 경험하는 불안정한 인식 데이터 문제를 해결하기 위하여 두 계층으로 구성된 데이터 처리 절차를 제시하였다. 본 논문에서 제시한 데이터 처리 절차를 실제사례에서 취합한 데이터에 적용하여 태그의 위치를 정확하게 파악하고 추가적인 업무 정보를 도출하는 것이 가능함을 확인하였다. 마지막으로 보다 안정적이고 효과적인 RFID 시스템 구축을 위하여 사례분석에서 경험한 추가적인 논의사항과 연구방향을 제시하였다.
