BACKGROUND:
背景:
As the nation embarks on the widespread deployment of EHRs, a variety of concomitant challenges and barriers must be addressed. One of these is interoperability, or the ability to exchange patient health information among disparate clinicians and other authorized entities in real time and under stringent security, privacy and other protections. Interoperability is an essential factor in using health information technology to improve the quality and efficiency of care in the United States. Interoperability is necessary for compiling the complete experience of a patient’s care, for maintaining a patient’s personal health records and for ensuring that complete health information is accessible to clinicians as the patient moves through various healthcare settings. Interoperability is needed for clinicians to make fact-based decisions so medical errors and redundant tests can be reduced. Interoperability is also critical to cost-effective and timely data collection for biosurveillance, quality measurement and clinical research. In short, interoperability is essential for realizing the key goals that are desired from health information technology.
当国家着手广泛实施EHR时,必须重视其相伴产生的各种挑战和阻碍。其中之一就是互操作性,即在严格的安全、隐私和其它保护条件下,在远隔着的医生和其它授权组织之间,实时地交换病人医疗信息的能力。这种互操作性,对于利用信息技术来改进全美国医疗服务的质量和效率,是一项基础因素。为了汇编病人的完整医护史、为了维护病人的个人健康纪录、以及为了在病人移动于不同医疗场所时确保其各有关医生能获得完整的医疗信息,互操作性都是必须的。医生需要互操作性来作出循证决策并降低医疗失误和重复检查,生物监控、质量衡测、和临床研究要求的低耗高效与及时的数据收集,互操作性也是关键性的。简而言之,对于实现医疗信息技术所期望的那些关键目标,互操作性是最基本的。
With the exception of a few isolated regional projects, the United States does not currently have meaningful health information interoperability capabilities. Moreover, the broad set of actions and tasks that are needed to achieve interoperability are not well-defined. It is known that interoperability requires a set of common standards that specify how information can be communicated and in what format. On this, there has been considerable effort and progress achieved by private sector organizations such as Health Level 7 (HL7), and by the American National Standards Institute (ANSI), both of which are voluntary consensus standards setting organizations. Also, HHS and other federal agencies have advanced the adoption of standards through the Consolidated Health Informatics (CHI) initiative, as well as the Public Health Information Network (PHIN) and National Electronic Disease Surveillance System (NEDSS) under the leadership of the Centers for Disease Control and Prevention (CDC). With HHS participation, HL7 has also created a functional model and standards for electronic health records.
除了少数隔绝着的地区性项目之外,全美国目前还没有有意义的医疗信息互操作能力,而且,达到互操作性所需要的广泛成套的行动和任务也没有很好地定义。大家都知道互操作性需要一套共同标准来确定信息以什么格式和如何能被通讯。对此,已经有私人组织如HL7、以及美国国家标准局ANSI进行并取得了相当大的努力和进步——这两者都是自发的多数同意式标准设定组织。同时,HHS和其它联邦机构也推进了对标准的采用,例如通过联合医疗信息学(CHI, Consolidated Health Informatics)倡议,以及疾病预防与控制中心CDC领导的公共卫生信息网PHIN和全国电子疾病监控系统NEDSS。随着HHS的加入,HL7也已经为电子病历创立了功能模型和标准。
However more remains to be done to achieve interoperability and to determine the process by which these tasks should be pursued in the public and private sectors. Clearly needed are interconnection tools such as mobile authentication, identification management, common web services architecture and security technologies. Also needed are precisely defined implementation regimens that are specified at the level of software code. There is also a need for common networking and communication tools to unify access and security. Aside from this, mechanisms for ensuring the sustainable operation of these components on a widespread and publicly available basis must be defined. There are potentially other components that may not be known at this time. The collective array of components that underlie nationwide interoperability is referred to as a National Health Information Network (NHIN) in the Framework.
然而,要达到互操作性,要确定让公共和私人组织从事那些任务所需遵循的程序,还有更多的事情要做。明确需要的(组分)是互联工具,如移动认证、身份管理、通用WEB服务架构、以及安全技术;还有需要的是精确定义的在软件代码水平上指定的实施规则,以及为统一信息的获取和安全所要求的通用联网与通讯工具。此外,为确保这些组分在广泛和公众可得的基础上能可持续地运作,还需要定义保障机制。还有一些其它潜在的组分,目前还不知道。构成全国性互操作性基础的这些组分集合阵列,在框架报告中被称为全国医疗信息网NHIN。
