Radio-frequency identification (RFID) technology is being used increasingly for its efficiency and safety. The goal of this study is to evaluate the RFID technology within a hospital information system (HIS) for better workflow management in a health promotion center. We developed an RFID (433 mHz) real-time tracking system to monitor patients at the room level. Then we implemented an automatic workflow management by integrating RFID system with HIS. If a patient has finished one examination, the next step is determined automatically by previous number of examined patients and duration in each examination room. We performed interrupted time-series analysis of the mean waiting time for patients in a health promotion center compared with a control group of outpatients in the hospitals radiology department before and after the implementation of an RFID-based system. After implementation of the RFID system, the mean waiting time of patients in the health promotion center decreased significantly (from 5.4 to 4.3 min, 20% decrease) compared with the control group (from 3.8 to 3.5 min, 8% decrease). The RFID system integrated with HIS increases workflow efficiency by shortening the mean waiting time during the workflow process and provides valuable real-time data for physicians and staff regarding workflow efficiency. © 2006 IEEE.

With the technology of sensor, RFID, and GPS, many researches are recently being carried out on monitoring animal behavior and interactions with the environment. Plus, the technology is applicable to develop new zoological systems for animal traceability, identification, and anti-theft. Yet, there is a lack of studies of providing zoos with intelligent animal tracking and management services based on RFID, GPS, and sensors. Accordingly, in this paper, we propose an intelligent animal situation tracking service for zoological gardens, based on GPS, RFID, and sensors. Firstly, we present a service scenario of animal situation tracking and introduce the tracking system configuration. The proposed system can provide real-time animal situation information such as the current location, bodily temperature, and pictures. Plus, it can track the animals based on the information even when they escape their cages. Next, we design and implement a prototype of the proposed animal situation tracking system. © 2010 IEEE.

Objectives: Seoul National University Bundang Hospital, which is the first Stage 7 hospital outside of North America, has adopted and utilized an innovative and emerging information technology system to improve the efficiency and quality of patient care. The objective of this paper is to briefly introduce the major components of the SNUBH information system and to describe our progress toward a next-generation hospital information system (HIS). Methods: SNUBH opened in 2003 as a fully digital hospital by successfully launching a new HIS named BESTCare, "Bundang hospital Electronic System for Total Care". Subsequently, the system has been continuously improved with new applications, including close-loop medication administration (CLMA), clinical data warehouse (CDW), health information exchange (HIE), and disaster recovery (DR), which have resulted in the achievement of Stage 7 status. Results: The BESTCare system is an integrated system for a university hospital setting. BESTCare is mainly composed of three application domains: the core applications, an information infrastructure, and channel domains. The most critical and unique applications of the system, such as the electronic medical record (EMR), computerized physician order entry (CPOE), clinical decision support system (CDSS), CLMA, CDW, HIE, and DR applications, are described in detail. Conclusions: Beyond our achievement of Stage 7 hospital status, we are currently developing a next-generation HIS with new goals of implementing infrastructure that is flexible and innovative, implementing a patient-centered system, and strengthening the IT capability to maximize the hospital value. © 2012 The Korean Society of Medical Informatics.

Critical value is defined as a result suggesting that the patient is in danger unless appropriate action is taken immediately. We designed an automated reporting system of critical values and evaluated its performance. Fifteen critical values were defined and 2-4 doctors were assigned to receive short message service (SMS).Laboratory results in LIS and EMR were called back to the DIA server. The rule engine named U-brain in the CDSS server was run in real-time and decision if the laboratory data was critical was made. The CDSS system for alerting of laboratory critical values was fast and stable without additional burden to the entire EMR system. Continuous communication with clinicians and feedback of clinical performance are mandatory for the refinement and development of user-friendly CDSS contents. Appropriate clinical parameters are necessary for demonstration of the usefulness of the system. © 2010 Springer-Verlag.

Objectives: We aimed to develop a common health information exchange (HIE) platform that can provide integrated services for implementing the HIE infrastructure in addition to guidelines for participating in an HIE network in South Korea. Methods: By exploiting the Health Level 7 (HL7) Clinical Document Architecture (CDA) and Integrating the Healthcare Enterprise (IHE) Cross-enterprise Document Sharing-b (XDS.b) profile, we defined the architectural model, exchanging data items and their standardization, messaging standards, and privacy and security guidelines, for a secure, nationwide, interoperable HIE. We then developed a service-oriented common HIE platform to minimize the effort and difficulty of fulfilling the standard requirements for participating in the HIE network. The common platform supports open application program interfaces (APIs) for implementing a document registry, a document repository, a document consumer, and a master patient index. It could also be used for testing environments for the implementation of standard requirements. Results: As the initial phase of implementing a nationwide HIE network in South Korea, we built a regional network for workers’ compensation (WC) hospitals and their collaborating clinics to share referral and care record summaries to ensure the continuity of care for industrially injured workers, using the common HIE platform and verifying the feasibility of our technologies. Conclusions: We expect to expand the HIE network on a national scale with rapid support for implementing HL7 and IHE standards in South Korea. ⓒ 2015 The Korean Society of Medical Informatics

Objectives: To design a cloud computing-based Healthcare Software-as-a-Service (SaaS) Platform (HSP) for delivering healthcare information services with low cost, high clinical value, and high usability. Methods: We analyzed the architecture requirements of an HSP, including the interface, business services, cloud SaaS, quality attributes, privacy and security, and multi-lingual capacity. For cloud-based SaaS services, we focused on Clinical Decision Service (CDS) content services, basic functional services, and mobile services. Microsoft’s Azure cloud computing for Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) was used. Results: The functional and software views of an HSP were designed in a layered architecture. External systems can be interfaced with the HSP using SOAP and REST/JSON. The multi-tenancy model of the HSP was designed as a shared database, with a separate schema for each tenant through a single application, although healthcare data can be physically located on a cloud or in a hospital, depending on regulations. The CDS services were categorized into rule-based services for medications, alert registration services, and knowledge services. Conclusions: We expect that cloudbased HSPs will allow small and mid-sized hospitals, in addition to large-sized hospitals, to adopt information infrastructures and health information technology with low system operation and maintenance costs. © 2015 The Korean Society of Medical Informatics.
