CDA，CCD-HL7版本3 [英] CDA, CCD - HL7 version 3

问题描述

我正在研究HL7版本3的CDA和CCD.有人可以告诉我CDA和CCD的目的是什么，为什么要使用它?我做了很多尝试，但我不知道，请帮助我. (如果我通过HL7第2版获得了所有信息，为什么我应该使用HL7第3版?)

解决方案

RE:CDA与CCD

来源:

CDA文档可以包含许多数据节，所有数据节都包含 叙述文字，其中一些包含结构化数据元素， 其中一些已编码.

CDA文档的类型很多，包括CCD，XDS-MS放电 摘要(HITSP C48)，历史和实物(HITSP C84)，实验室报告 (HITSP C37)等.

.

护理文档的连续性(CCD)-CCD根据HL7临床文档架构第2版(CDA)规范描述了约束条件 ASTM E2369-05标准规范中规定的要求 护理记录的连续性(CCR).它旨在作为替代 实施到ASTM ADJE2369中指定的那些 致力于实施HL7的机构或组织 临床文件架构.护理记录的连续性(CCR) 是最相关的行政，人口统计， 和有关患者医疗保健的临床信息事实，包括 一个或多个医疗保健相遇2. 医疗保健从业者，系统或环境以汇总所有 有关患者的相关数据，并将其转发给另一位从业者， 系统或设置以支持护理的连续性.

CCD只是CDA文件的一种.其他类型的CDA文档可以 包含一些相同的CCD部分，但也包含不同的部分.

源PDF包含一些其他信息.

RE:HL7 v2与HL7 v3 参见:

• 白皮书:" HL7演变:比较HL7版本2和3 "

引用那篇论文(我相信是在2012年写的)

迄今为止，HL7 V3消息尚未在内部广泛采用. 美国作为交换临床数据的一种手段.当前HL7 V2 供应商通常处于观望"模式，直到他们的客户 需求V3.监管机构是一个例外.

可以问一个明显的问题:"HL7 V2现在会消失吗? V3发行了吗?"我们相信答案是不会很快". 数以百万计的美元和无数的时间投入到了开发和 维护HL7 V2接口.仅从财务角度来看， HL7 V2会很快消失是不可想象的.

白皮书中包含有关该主题的更多信息.您也可以查看路线图，该路线图显示了针对CDA R3的计划工作.我不是该领域的专家. (非常感谢.这些东西太疯狂了.)我怀疑关于v2与v3的好处的更有用的答案将需要评估您的具体情况.

(首先，我不确定这个问题是否与编程有关.在这里，您可能会比较幸运: http://healthcareit.stackexchange.com/ (UPD: Healthcare IT 网站测试期间没有足够的活动，并且已经关闭))

I am working on CDA as well as CCD of HL7 version 3. Can someone tell me what is the purpose of CDA and CCD and why it is used? I tried a lot to figure out but i can't, please help me. (if i get all the information through HL7 version 2 why should i use HL7 version 3?)

RE: CDA vs. CCD

Source: HITSP_09_N_451.pdf

Clinical Document Architecture (CDA) - CDA is an HL7 document markup standard that specifies the structure and semantics of "clinical documents" for the purpose of exchange. CDA documents derive their machine processable meaning from the HL7 Reference Information Model (RIM) and use the HL7 Version 3 Data Types. CDA is a flexible XML-based clinical document architecture. CDA itself is not a specific document, but can be used to express many types of documents.

A CDA document can contain many data sections, all of which contain narrative text, and some of which contain structured data elements, some of which are coded.

There are many types of CDA documents, including CCD, XDS-MS Discharge Summary (HITSP C48), History and Physical (HITSP C84), Lab Report (HITSP C37), etc.

.

Continuity of Care Document (CCD) - CCD describes constraints on the HL7 Clinical Document Architecture, Release 2 (CDA) specification in accordance with requirements set forward in ASTM E2369-05 Standard Specification for Continuity of Care Record (CCR). It is intended as an alternate implementation to the one specified in ASTM ADJE2369 for those institutions or organizations committed to implementation of the HL7 Clinical Document Architecture. The Continuity of Care Record (CCR) is a core data set of the most relevant administrative, demographic, and clinical information facts about a patient’s healthcare, covering one or more healthcare encounters.2 It provides a means for one healthcare practitioner, system, or setting to aggregate all of the pertinent data about a patient and forward it to another practitioner, system, or setting to support the continuity of care.

CCD is just one type of CDA document. Other types of CDA documents can contain some of the same CCD sections, but different sections as well.

The source PDF includes some additional information.

RE: HL7 v2 vs HL7 v3 See:

• Whitepaper: "The HL7 Evolution: Comparing HL7 Versions 2 and 3"

Quoting from that paper (which I believe was written in 2012):

To date, HL7 V3 messages have not been widely adopted within the United States as a means to exchange clinical data. Current HL7 V2 vendors are generally in a "waitand-see" mode until their customers demand V3. Regulatory agencies are one exception.

An obvious question can be asked: "Will HL7 V2 simply disappear now that V3 is released?" We believe the answer is "Not anytime soon." Millions of dollars and countless hours have gone into developing and maintaining HL7 V2 interfaces. From a financial perspective alone, it is inconceivable that HL7 V2 will quickly disappear.

The whitepaper includes significantly more information on the topic. You might also check out this roadmap showing planned work towards CDA R3. I'm not an expert in this field. (Thankfully so. This stuff is crazy complex.) I suspect a more useful answer on benefits of v2 vs. v3 would require assessing your specific situation.

(Fwiw, I'm not sure this question classifies as programming related. You might have better luck here: http://healthcareit.stackexchange.com/ (UPD: The Healthcare IT site didn't have enough activity during the beta, and has been closed))
