ISO 18308:2011定义了处理、管理和传递电子健康记录（EHR）信息的系统体系结构的一系列要求:EHR体系结构。制定这些要求是为了确保这些EHR忠实于医疗服务的需求、临床有效和可靠、道德健全、符合现行法律要求、支持良好的临床实践，并促进出于多种目的的数据分析。 ISO 18308:2011没有规定EHR系统需要满足的直接患者护理或其他用例的全套要求，但ISO 18308:2011定义的要求确实有助于此类系统内EHR信息的管理。

ISO 18308:2011 defines the set of requirements for the architecture of a system that processes, manages and communicates electronic health record (EHR) information: an EHR architecture. The requirements are formulated to ensure that these EHRs are faithful to the needs of healthcare delivery, are clinically valid and reliable, are ethically sound, meet prevailing legal requirements, support good clinical practice and facilitate data analysis for a multitude of purposes. ISO 18308:2011 does not specify the full set of requirements that need to be met by an EHR system for direct patient care or for other use cases, but the requirements defined by ISO 18308:2011 do contribute to the governance of EHR information within such systems.
