Abstract

This paper discusses the design and the implementation of the interface between the Medical Image Access System for the Intensive Care Unit (MIAS/ICU) and the hospital/radiology information systems (HIS/RIS) operated by Information Systems Services (ISS) of the University Medical Center, Tucson, Arizona. The report addresses the problem of obtaining current status information on patients to be used in the MIAS/ICU system. Hospital information systems operated by ISS exchange patient information using Health Level 7 (HL7) messages over the hospital Ethernet network. The MIAS/ICU consists of 5 components: an image reader to read image plates from portable x-ray units; Image Server to store images; Data Server which is a database for patient information; Viewing Workstation a commercial workstation with two monitors used by physicians at ICU for early, uno cial viewing of images; these components are integrated by an FDDI network. These images need to be supplemented by patient's current status information. A gateway was designed and implemented to extract useful data from HL7 messages and pass them to the data server. Most medical information exchange interface designs tend to be proprietary, hard-wired, and application speci c. This design and implementation is open; can be easily customizable to suit di erent medical institutions; allowed us to exibly experiment with di erent con gurations; and is operating reliably in a clinical setting. It is a generic design for interfaces between medical information applications. This paper brie y reviews the HL7 standard. It then provides an overview of the MIAS/ICU project, the gateway software architecture, the gateway software implementation, and design limitations. This gateway is currently operational within the MIAS/ICU system at University Medical Center, Tucson, Arizona. 1 2 1 This work is supported by: a gift from Fuji Medical Systems U.S.A., funding and support from University Medical Center, and an equipment grant from Digital Equipment Corporation. 2 International Phoenix Conference on Computers and Communications (IPCCC), Phoenix, Arizona, April 12-15, 1994

重症监护病房与医院/放射科信息系统的接口设计

本文讨论了重症监护室医学图像访问系统(MIAS/ICU)与由亚利桑那图森大学医学中心信息系统服务(ISS)运营的医院/放射信息系统(HIS/RIS)之间接口的设计和实现。该报告解决了获取MIAS/ICU系统中使用的患者当前状态信息的问题。由ISS操作的医院信息系统通过医院以太网使用健康级别7 (HL7)消息交换患者信息。MIAS/ICU由5个部件组成:一个图像读取器，用于读取便携式x光机的图像板;图像服务器用于存储图像;数据服务器是一个病人信息的数据库;观看工作站:带有两台监视器的商用工作站，供ICU医生用于早期、非社交观看图像;这些组件通过FDDI网络集成。这些图像需要补充患者的当前状态信息。设计并实现了一个网关，用于从HL7消息中提取有用的数据并将其传递给数据服务器。大多数医疗信息交换接口设计往往是专有的、硬连接的和特定于应用程序的。这种设计和实现是开放的;可轻松定制，以适应不同的医疗机构;让我们能够灵活地试验不同的结构;并且在临床环境中运行可靠。它是医疗信息应用程序之间接口的通用设计。本文简要回顾了HL7标准。然后概述了MIAS/ICU项目、网关软件体系结构、网关软件实现和设计限制。该网关目前在亚利桑那州图森市大学医学中心的MIAS/ICU系统内运行。这项工作得到了:美国富士医疗系统公司的捐赠，大学医学中心的资助和支持，以及数字设备公司的设备资助。2国际凤凰城计算机与通信会议(IPCCC)， 1994年4月12日至15日，亚利桑那州凤凰城
