Interoperability has been deemphasized from the hospital information system in general, because it is operated independently of other hospital information systems. This study proposes a future-oriented hospital information system through the design and actualization of the HL7 clinical document architecture. A clinical document is generated using the hospital information system by analysis and designing the clinical document architecture, after we defined the item regulations and the templates for the release form and radiation interpretation form. The schema is analyzed based on the HL7 reference information model, and HL7 interface engine ver.2.4 was used as the transmission protocol. This study has the following significance. First, an expansion and redefining process conducted, founded on the HL7 clinical document architecture and reference information model, to apply international standards to Korean contexts. Second, we propose a next-generation web based hospital information system that is based on the clinical document architecture. In conclusion, the study of the clinical document architecture will include an electronic health record (EHR) and a clinical data repository (CDR), and also make possible medical information-sharing among various healthcare institutions.

For the sharing and exchange of information between medical clinics, the clinical document has to be built on a standardized protocol such as a HL7-CDA. But it is difficult to exchange information between medical clinics because clinical document such as electronic medical record that include text and image, have different structure of document and type of expression. In this paper, we propose the electronic medical record system based on HL7-CDA that can share and exchange clinical information between medical institute. For this purpose, we have to design the schema of the clinical document architecture after we select the essential items of medical record and define templates. The proposed system can minimize integrating process and save parsing time when clinical information exchange and refer, by converting electronic medical record to base64 encoding scheme and integrate it in a XML document.

This study proposes the actualization of a standard data model for activities through the development of clinical document architecture for medication administration using the health level 7 development frameworks(HDF) process based on object oriented analysis and development method of health level 7 V 3. Medication administration is the most common activity performed by clinical professionals at healthcare settings. A standardized information model and structured hospital information system are necessary to achieve evidence-based clinical activities. We had used HDF and various tools(Rose tree, RMIM designer, V3 generator) to create the clinical document architecture(CDA). This allowed us to illustrate each step of the HDF in the administration of medication. This study generated a information model of the medication administration process, which is one clinical activity. It should become a fundamental conceptual model for understanding international standard methodology by information technology(IT) developers with the objective of modeling healthcare information systems.

HL7 released V3 CDA(Clinical Document Architecture) and V2.x message standards for medical information exchange. Currently, these standards are successfully adopted by a number of nations across the globe. However, substantial amount of time is required to develop and implement these standards. Moreover, developers need a lot of time to understand these standards. To solve these issues from 2011, the HL7 standard framework started to discuss Fast Healthcare Interoperability Resources(FHIR) as next generation standard of healthcare information exchange. People's interests toward personal health record and smartphone penetration rate are growing and increasing rapidly. Therefore, our research team believes it is necessary to develop a PHR profiling system which could be accessed by using a smartphone and we developed the system. Through a FHIR Profile editor tool developed in Furore, we found that improvements could be made in generating and changing the profile. In order to build the PHR Profiling system, an Open-API on FHIR is used for exchanging information between electronic medical record system and PHR Profiling system. In the PHR Profiling system, the transactions of information between two systems are provided by RESTful service. In this study, we verify the efficiency of development of the PHR Profiling system through FHIR.

HL7(Health Level 7)은 보건의료 분야에서 ANSI에서 승인한 SDO(Standards Developing Organization)들 중의 하나이다. 대부분의 SDO들은 약제. 의료 장비 이미지, 보험 처리 등과 같은 보건의료 분야에서의 표준을 만든다. HL7의 영역은 진료와 병원 행정적인 부분이다. HL7에서는 Version2.3, Version2.4, Version3.0 등을 포함해 Data Model. Arden Syntax, CCOW(Common Context Object Workgroup) CDA(Clinical Document Architecture) 등의 표준을 만들어 나간다. 본 논문에서는 이 표준들 중 CCOW에 대해 알아보고. 기존 Agent System에 좀 더 지능적이고 자율적인 CCOW 서비스를 제공하는 방안을 알아본다.

As the medical environment field has been facilitated by the rapid development of the information technologies and ubiquitous healthcare service based on network, the exchange of medical information between hospitals become more and more important. However, although most electrocardiograph vendors have provided digital modalities and their ECG data management systems, these were proprietary and not compatible with each other due to multiplicity of vendor specific formats and lack of open ECG data standards. Therefore, we aim to design and develop the ECG management system for archiving, saving, searching, viewing and transferring ECG data and the diagnostic reports. And the system is based on Clinical Document Architecture (CDA) developed by HL7 and DICOM Waveform Standard for the exchange of the structured diagnostic reports and the transfer of ECG data.

Health Level Seven(HL7)에서 V2.x, V3 보다 향상된 FHIR(Fast Healthcare Interoperabilty Resources)를 표준을 개발하고 있고, 이를 채택한 솔루션 개발이 활발하고, 각 국가 의료환경에서의 검증이 필요하다. 현재 미국에서 성공적으로 널리 사용되는 V2.x Message와 V3 Clinical Document Architecture(CDA)가 존재 하지만, 이 기술 표준들을 개발하고 사용하는데 긴 시간 투자의 문제점이 있다. 현재 V4로 불리우는 개선된 FHIR를 사용함으로 이러한 문제점을 해결할 방법인지 확인한다. 개인건강기록 관리 또한 사회적인 관심을 끌고 있고, 스마트폰 보급률이 급격히 증가하는 함을 반영하여 개인건강기록 관리 시스템을 스마트폰으로 접속 가능한 시스템으로 개발한다. 이를 구축하기 위해서는 Electronic Medical Record(EMR) 시스템과 Personal Health Profiling(PHP) 시스템간의 정보교류를 FHIR Open API로 구성한다. PHP 시스템에서는 이들 트랜잭션을 RESTful 서비스로 제공한다. 본 연구에서는 FHIR기반의 PHP 시스템을 통해 개인건강관리 시스템의 효율성을 검증하고자 한다.

Objectives: The demand for hospice has been increasing among patients with cancer. This study examined the current hospice referral scenario for terminally ill cancer patients and created a data form to collect hospice information and a modified health information exchange (HIE) form for a more efficient referral system for terminally ill cancer patients. Methods: Surveys were conducted asking detailed information such as medical instruments and patient admission policies of hospices, and interviews were held to examine the current referral flow and any additional requirements. A task force team was organized to analyze the results of the interviews and surveys. Results: Six hospices completed the survey, and 3 physicians, 2 nurses, and 2 hospital staff from a tertiary hospital were interviewed. Seven categories were defined as essential for establishing hospice data. Ten categories and 40 data items were newly suggested for the existing HIE document form. An implementation guide for the Consolidated Clinical Document Architecture developed by Health Level 7 (HL7 CCDA) was also proposed. It is an international standard for interoperability that provides a framework for the exchange, integration, sharing, and retrieval of electronic health information. Based on these changes, a hospice referral scenario for terminally ill cancer patients was designed. Conclusions: Our findings show potential improvements that can be made to the current hospice referral system for terminally ill cancer patients. To make the referral system useful in practice, governmental efforts and investments are needed.
