HL7在HIS系统中的应用研究

医院信息系统（HIS）间的＂异构＂问题由来己久,而业务的发展要求实现医疗信息的交换和共享。本课题引入了HL7标准作为医院信息系统间共同遵循的数据交换协议,以实现异构系统间数据的交换。文章以HL7消息作为主要研究对象,设计一个HL7消息的构建、解析演示系统。中间件包括两个功能模块：HL7消息的构建/解析模块和消息传输模块。消息的格式基于XML技术。系统的演示表明,在对现有系统不作更改的前提之下,采用外挂中间件的模式,能在系统间正常地处理传输基于XML格式的HL7消息,很好地解决了异构系统间数据的交换,符合当前的需要。本课题所作的探讨也为将来深入的研究工作提供了帮助。

Data interchange standards in healthcare IT--computable semantic interoperability: now possible but still difficult, do we really need a better mousetrap?

The following article on HL7 Version 3 will give readers a glimpse into the significant differences between "what came before"--that is, HL7 Version 2.x--and "what today and the future will bring," which is the HL7 Version 3 family of data interchange specifications. The difference between V2.x and V3 is significant, and it exists because the various stakeholders in the HL7 development process believe that the increased depth, breadth, and, to some degree, complexity that characterize V3 are necessary to solve many of today's and tomorrow's increasingly wide, deep and complex healthcare information data interchange requirements. Like many healthcare or technology discussions, this discussion has its own vocabulary of somewhat obscure, but not difficult, terms. This article will define the minimum set that is necessary for readers to appreciate the relevance and capabilities of HL7 Version 3, including how it is different than HL7 Version 2. After that, there will be a brief overview of the primary motivations for HL7 Version 3 in the presence of the unequivocal success of Version 2. In this context, the article will give readers an overview of one of the prime constructs of Version 3, the Reference Information Model (RIM). There are 'four pillars that are necessary but not sufficient to obtain computable semantic interoperability." These four pillars--a cross-domain information model; a robust data type specification; a methodology for separating domain-specific terms from, as well as binding them to, the common model; and a top-down interchange specification methodology and tools for using 1, 2, 3 and defining Version 3 specification--collectively comprise the "HL7 Version 3 Toolkit." Further, this article will present a list of questions and answers to help readers assess the scope and complexity of the problems facing healthcare IT today, and which will further enlighten readers on the "reality" of HL7 Version 3. The article will conclude with a "pseudo-code" argument in favor of the adoption of HL7 Version 3, framed by citing the recommendation of the Interoperability Consortium for the use of HL7 Version 3 as a critical component in the National Health Information Infrastructure.

Technological and Organizational Context around Immunization Reporting and Interoperability in Minnesota

Background: Immunization information systems (IIS) operate in an evolving health care landscape with technology changes driven by initiatives such as the Centers for Medicare and Medicaid Services EHR incentive program, promoting adoption and use of electronic health record (EHR) systems, including standards-based public health reporting. There is flux in organizational affiliations to support models such as accountable care organizations (ACO). These impact institutional structure of how reporting of immunizations occurs and the methods adopted.Objectives: To evaluate the technical and organizational characteristics of healthcare provider reporting of immunizations to public health in Minnesota and to assess the adoption of standardized codes, formats and transport.Methods: Data on organizations and reporting status was obtained from Minnesota IIS (Minnesota Immunization Information Connection: MIIC) by collating information from existing lists, specialized queries and review of annual reports. EHR adoption data of clinics was obtained in collaboration with informatics office supporting the Minnesota e-Health Initiative. These data from various sources were merged, checked for quality to create a current state assessment of immunization reporting and results validated with subject matter experts.Results: Standards-based reporting of immunizations to MIIC increased to 708 sites over the last 3 years. A growth in automated real-time reporting occurred in 2013 with 143 new sites adopting the method. Though the uptake of message standards (HL7) has increased, the adoption of current version of HL7 and web services transport remains low. The EHR landscape is dominated by a single vendor (used by 40% of clinics) in the state. There is trend towards centralized reporting of immunizations with an organizational unit reporting for many sites ranging from 4 to 140 sites.Conclusion: High EHR adoption in Minnesota, predominance of a vendor in the market, and centralized reporting models present opportunities for better interoperability and also adaptation of strategies to fit this landscape. It is essential for IIS managers to have a good understanding of their constituent landscape for technical assistance and program planning purposes.

HL7 version 3.0: a preview for CIOs,managers, and programmers

HL7-based data exchange will be a critical component of the healthcare enterprise of the future. Clearly, the healthcare marketplace is driving toward full interoperability, in which HL7 plays a leading role. Version 3.0 effectively addresses the limitations of previous versions, and expands both the capabilities and value of the HL7 standard. The inclusion of new technologies such as XML ensures HL7's longevity, and its testing and validation capabilities are significant improvements. Version 3.0's RIM is the key "artifact" and represents the most comprehensive data model for healthcare. Although adoption of version 3.0 will take planning, time, and money, the resulting improvements offer significant benefits and efficiencies to providers and vendors alike.
