Rapid access to patient information is critical for care in both inpatient and outpatient settings. Ancillary systems (Lab, Microbiology, Electrocardiogram (ECG), Echocardiography, etc.) contain test result information. Mayo Foundation is piloting an Electronic Results Inquiry System (ERIS), using the Phamis Lastword database, that aggregates some of this information into a central location. The results may then be accessed by workstations or forwarded to surgical, critical care, and transplant information systems. All communications messages, except for the workstation interface, will be based on the Health Level 7 (HL7) specification, version 2.1. The specification has benefitted Mayo by shortening interface design effort and providing common messages between various computer systems. At this time, HL7 is the most practical solution for these interfaces[1]. HL7 gives all parties involved in the interfaces a "blueprint" to begin design. Unlike a formal blueprint, the specification is flexible and handles most of the needs encountered to date. The areas in which the specification was lacking were reported to the HL7 working group. These areas have been addressed by the working group to allow completion of the interfaces described here. This paper describes the HL7 interfaces to ERIS, with the ECG result and client query interfaces emphasized.
快速获取患者信息对于住院和门诊护理都至关重要。辅助系统（实验室、微生物学、心电图（ECG）、超声心动图等）包含检测结果信息。梅奥基金会正在使用Phamis Lastword数据库试点一个电子结果查询系统（ERIS），该系统将其中一些信息汇总到一个中心位置。然后，这些结果可以通过工作站访问，或转发到手术、重症监护和移植信息系统。除工作站接口外，所有通信消息都将基于健康级别7（HL7）规范2.1版。该规范通过缩短接口设计工作并在各种计算机系统之间提供通用消息，使梅奥受益。目前，HL7是这些接口最实用的解决方案[1]。HL7为接口涉及的所有各方提供了一个开始设计的“蓝图”。与正式蓝图不同，该规范很灵活，能够满足迄今为止遇到的大多数需求。规范中存在不足的领域已报告给HL7工作组。工作组已解决了这些领域的问题，以便完成此处所述的接口。本文描述了ERIS的HL7接口，重点是ECG结果和客户端查询接口。
