본 논문에서는 병원간의 정보를 교환하기 위한 목적으로 정의된 의료 분야의 표준기관인 HL7에서 제안하는 Clinical Document Architecture(CDA)문서를 관리하기 위한 시스템을 제안한다. CDA Manager라는 이 시스템은 각 병원의 관계형 데이터베이스인 CDA local repository에서 CDA문서를 저장, 검색, 수정의 기능을 제공한다. 본 논문에서는 XML로 기술된 CDA문서의 특성을 살려 테이블을 설계하고 검색속도를 향상시켰다.

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.

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.

HITSP(Healthcare Information Technology Standards Panel)은 헬스 케어 관련 산업의 상호 운용성을 위해 일반적으로 수용되고 유용한 표준들을 선별하여 표준 세트를 제공하는 것을 목적으로 한다. HITSP에서는 평생전자건강진료정보(EHR, Electronic Health Record)의 활성화를 위해 첫 번째 해결해야 할 영역으로 검사실 결과 정보 교류를 정하였다. 이에 본 논문에서는 검사실 결과 정보 교류를 위한 방법으로 HITSP에서 제시하는 HL7 버전 2.x 메시지와 CDA 방법 중 인증(authentication) 처리가 가능하고 영속성(persistence)이 있는 CDA 방법을 선택하였다. 또한 CDA를 작성하고 처리하는 방법을 제시하고, 더 나아가 평생전자건강진료정보(EHR)를 위해 CDA를 적용하여 검사실 결과 정보를 교류하여 보았다. 이에 병원과 EHR 시스템의 상호 운용성이 높아져 진료 과정의 효율성을 높일 수 있었고 환자와 의료진에게 양질의 검사 결과 정보를 제공할 수 있었다.

The recent development of embodiment technology of the medical images makes most medical institutions introduce PACS in haste. However, while many older HIS and PACS systems are not yet capable of some of the integration, several new systems are moving rapidly in that direction. Typical PACS system architecture begins with the HIS since this is where the correct patient demographic information and in many cases the orders originate. So, PACS developed convenience of users and to satisfy user's demand because of financial limitations and administrator-oriented considerations in the process of development. Therefore, we have developed a CDA (Clinical Document Architecture) based PACS with HIS, by which we can search and refer to the patient's medical images and information with few restrictions of time and space for diagnosis and treatment. Target model of this research limited to 135 of hospital have 200 beds. We'll make more effort to develop the application which insures the better quality and information of medical images. Medical Image History manages the patient's image files and various medical informations like film chart in connection with time. This trial will contribute to the reduction of the financial loss caused by unnecessary devices and improve the quality in the medical services. The demand on the development of the program which refers to the medical data quickly and keeps them stable will be continued by the medical institute. This will satisfy the client's demand and improve the service to the patients in that the program will be modified from the standpoint of the users.
