A management strategy of monitor data in ICU based on data stream technology 基于数据流技术的ICU监护数据管理策略
Yongsheng Tan, Yibing Wang, Hongyan Li
The data produced by such medical monitor devices as ventilators, cardiac monitors in the ICU, arrive in multiple, continuous, rapid, time-varying data streams. Such data can not be stored entirely because of the storage devices limitation and the interference data produced by doctors' or nurses' medical operations and patients' activities. The present ICU systems using a relational database to store and manipulate data only provides the "operator-dependent" way to collect these stream data at fixed time intervals set by doctors. In this way, some important monitor data may be ignored, but some interference data may be collected. So the quality of data management can not meet the needs of doctors' and nurses'. In this paper, after deeply analyzing the features of the stream monitor data in the ICU, we talk about using data stream technology to solve the problem. Before the stream data arriving, doctors will pre-establish some data collecting rules based on patients' illness status such as fixed data collecting time intervals, data alarming range and level, and so on. When the monitor data arriving, they will be analyzed and manipulated by the pre-defining query rules above pre-established. So it can provide a "patient-dependent" way to collect not only the monitor data affixed time intervals when patients in good condition, but also all the monitor data when they are in critically ill situation. Furthermore, in this paper we also provide a way to deal with the interference data produced by monitor devices. Data stream technology can supply a gap in the management of the stream monitor data which is based on a relational database, and improve the quality of the data management in the ICU.
医疗监护设备产生的数据,如ICU中的呼吸机、心脏监护仪,以多个、连续、快速、时变的数据流到达。由于存储设备的限制,以及医生或护士的医疗操作和患者的活动产生的干扰数据,这些数据不能完全存储。目前的ICU系统使用关系数据库来存储和操作数据,仅提供“依赖于操作员”的方式,以医生设定的固定时间间隔收集这些流数据。这样,一些重要的监测数据可能会被忽略,但可能会收集到一些干扰数据。因此,数据管理的质量不能满足医生和护士的需求。本文在深入分析ICU流监控数据特点的基础上,探讨了利用数据流技术解决这一问题。在流数据到达之前,医生会根据患者的病情预先建立一些数据采集规则,如固定的数据采集时间间隔、数据报警范围和级别等。当监视器数据到达时,它们将由上面预先建立的预定义查询规则进行分析和操作。因此,它可以提供一种“患者依赖”的方式,既可以收集患者病情良好时固定时间间隔的监护数据,也可以收集患者危重时的所有监护数据。此外,本文还提供了一种处理监控设备产生的干扰数据的方法。数据流技术可以弥补基于关系数据库的流监测数据管理的不足,提高ICU数据管理的质量。

A framework for a clinical reasoning knowledge warehouse 临床推理知识库框架
Klaus Vilstrup Pedersen
In many areas of the medical domain, the decision process i.e. reasoning, involving health care professionals is distributed, cooperative and complex. This paper presents a framework for a clinical reasoning knowledge warehouse that combines theories and models from artificial intelligence, knowledge management systems and business intelligence to make context based, patient case specific analysis and knowledge management. The knowledge base integrates three sources of information that supports clinical reasoning: general information, guidelines and health records. New generalized knowledge is stored and made accessible when relevant to the reasoning context and the specific patient case. Furthermore, the information structure supports the creation of new generalized knowledge using data mining tools. The patient case is divided into an observation level and an opinion level. At the opinion level, reasoning participants can express their argument based opinions about a patient case, thereby enhancing the knowledge about the state of and plans for the patient. An opinion language that supports expressing a possible imprecise/uncertain opinion based on imprecise/uncertain/incomplete arguments is introduced. Finally, case based reasoning is used for retrieving similar patient cases and adapt the opinions in the current case.
在医疗领域的许多领域,决策过程,即推理,涉及卫生保健专业人员是分布式的,合作的和复杂的。本文提出了一个临床推理知识库的框架,该框架结合了人工智能、知识管理系统和商业智能的理论和模型,实现了基于上下文的、针对具体病例的分析和知识管理。知识库集成了支持临床推理的三个信息源:一般信息、指南和健康记录。当与推理上下文和特定患者病例相关时,新的广义知识被存储和访问。此外,信息结构支持使用数据挖掘工具创建新的广义知识。病例分为观察级和意见级。在意见层面,推理参与者可以表达他们对患者病例的基于论点的意见,从而增强对患者状态和计划的了解。介绍了一种支持基于不精确/不确定/不完整论据表达可能的不精确/不确定意见的意见语言。最后,使用基于案例的推理方法检索相似的患者案例,并对当前案例中的观点进行调整。

Medical image retrieval and registration: towards computer assisted diagnostic approach 医学图像检索与配准:迈向计算机辅助诊断方法
Md. Mahmudur Rahman, Tongyuan Wang, B. Desai
A large number of medical images in digital format are generated by hospitals and clinics every day. Such images constitute an important source of anatomical and functional information for diagnosis of diseases, medical research and education. These images include high-resolution 2-D or 3-D spatial and temporal data of various modalities (CT, MRI, X-ray, ultrasound etc.) require effective processing and organization techniques. Two of the most important techniques along this direction are; image retrieval and image registration. Image retrieval is the technique to find similar images from an image archive by their textual and visual contents and image registration is the establishment of correspondences between images or between image and physical space. Characteristics of medical images differ significantly from other general-purpose images and hence require special treatment. This article presents a highlight of recent research in medical image retrieval and registration, main techniques and trends, key issues and limitations. We also point out some promising research directions and propose a system architecture for computer aided diagnosis, where both technologies can be integrated and complement each other.
医院和诊所每天产生大量的数字格式医学图像。这些图像是疾病诊断、医学研究和教育的解剖学和功能信息的重要来源。这些图像包括各种模式(CT、MRI、x射线、超声等)的高分辨率二维或三维时空数据,需要有效的处理和组织技术。沿着这个方向的两个最重要的技术是;图像检索和图像配准。图像检索是根据图像的文本和视觉内容从图像档案中找到相似图像的技术,图像配准是建立图像之间或图像与物理空间之间的对应关系。医学图像的特征与其他通用图像有很大不同,因此需要特殊处理。本文介绍了近年来医学图像检索与配准的研究进展、主要技术和发展趋势、存在的关键问题和局限性。指出了计算机辅助诊断的研究方向,并提出了一种计算机辅助诊断的系统体系结构,使两种技术能够相互集成和互补。

Integrating remote health actors to an e-health intuitive cooperation platform development 将远程医疗参与者集成到电子医疗直观合作平台开发中
X. Urtubey, F. Uminsky, M. Petrich, R. Zadra, P. Felgaer, P. Orezzoli, C. Muñante
The "Agenda for the Connectivity in the Americas" defines health as an area of greatest importance to society; simultaneously ICT are seen by major telehealth players as means and tools for human health development. It is then extremely important not only to give access to connectivity to isolated areas, but also to integrate local health actors in each project. This integration is planed in all E-lLnk Americas Health Project's development steps: from evaluation of the user's needs, coordination of the activities and results evaluation. This paper describes the effort to start simultaneously telehealth pilot project in four Central American countries in isolated areas and the development, with local leaders decisive participation, of a eHealth cooperative platform's prototype based on the health needs study's results. These actions merged in a workshop which aimed to the complete integration of local players in the prototype development as well in the pilot's first phase's planning.
《美洲互联互通议程》将卫生定义为对社会最重要的领域;同时,信息通信技术被主要远程保健参与者视为促进人类健康发展的手段和工具。因此,极其重要的是,不仅要为偏远地区提供连接,而且要将当地卫生行为体纳入每个项目。这种整合是在e - link美洲卫生项目的所有开发步骤中规划的:从评估用户需求、协调活动到结果评估。本文描述了在四个中美洲偏远地区国家同时启动远程医疗试点项目的努力,以及在当地领导人果断参与下,根据卫生需求研究结果开发电子卫生合作平台原型的情况。这些行动合并在一个研讨会上,目的是在原型开发和试点第一阶段的规划中完全整合当地参与者。

Managing Pan-European mammography images and data using a service oriented architecture 使用面向服务的体系结构管理泛欧乳房x线摄影图像和数据
S. Amendolia, F. Estrella, R. McClatchey, D. Rogulin, T. Solomonides
Medical conditions such as breast cancer, and mammograms as images, are extremely complex with many degrees of variability across the population. An effective solution for the management of disparate mammogram data sources that provides sufficient statistics for complex epidemiological study is a federation of autonomous multi-centre sites which transcends national boundaries. Grid-based technologies are emerging as open-source standards-based solutions for managing and collaborating distributed resources. In the light of these new computing solutions, the MammoGrid project, as one example of a HealthGrid, is developing a Grid-aware medical application which manages a European-wide database of mammograms. The MammoGrid solution utilizes the grid technologies in seamlessly integrating distributed data sets and is investigating the potential of the Grid to support effective co-working among mammogram analysts throughout the EU.
医疗条件,如乳腺癌和乳房x光照片,是非常复杂的,在人群中有很多程度的差异。为复杂的流行病学研究提供充分统计数据的不同乳房x线照片数据源的管理的有效解决方案是建立一个超越国界的自治多中心站点联盟。基于网格的技术正在作为基于开源标准的解决方案出现,用于管理和协作分布式资源。鉴于这些新的计算解决方案,作为健康网格的一个例子,乳房x线网格项目正在开发一个网格感知医疗应用程序,该应用程序管理一个欧洲范围的乳房x线照片数据库。乳房造影网格解决方案利用网格技术无缝集成分布式数据集,并正在研究网格的潜力,以支持整个欧盟乳房造影分析人员之间有效的协同工作。

ICUIS: a rule-based intelligent ICU information system ICUIS:基于规则的智能ICU信息系统
Yu Fan, Hongyan Li
In the modern Intensive Care Unit, the high quality management of the patients' data produced by the medical devices is seriously important for improving the treating quality. Besides, since the data in ICU is often multiple, continuous, rapid and time-varying, a data stream processing module should be used to manage, store and display the patient data. ICUIS, a J2EE based ICU information system, imports rule mechanism as well as data stream processor to automatically manage the patient data, and can not only gather the sampling data to record the daily condition of a patient, but also send out an alarm according to the rule when an exceptional data occurs. This paper introduces the rule model, representing language, state conversion and processing flow in the system. ICUIS is different from the other systems because of its following characteristics: rule based intellectualized monitoring and alarming, powerful data stream management, patient-dependent information managements, and the expansibility and adaptability supported by J2EE platform and component-based architecture.
在现代重症监护病房中,对医疗设备产生的患者数据进行高质量的管理,对提高治疗质量至关重要。此外,由于ICU数据多、连续、快速、时变等特点,需要使用数据流处理模块对患者数据进行管理、存储和显示。ICUIS是一个基于J2EE的ICU信息系统,它引入规则机制和数据流处理器对患者数据进行自动管理,不仅可以采集采样数据记录患者的日常情况,还可以在数据出现异常时根据规则发出报警。介绍了系统中的规则模型、表示语言、状态转换和处理流程。ICUIS不同于其他系统的特点是:基于规则的智能化监测报警、强大的数据流管理、基于患者的信息管理,以及J2EE平台和基于组件的体系结构所支持的可扩展性和适应性。

East meets west to cure healthcare ills using information technology 东方与西方相遇,利用信息技术治疗医疗保健疾病
D. Baker
Although a half-world apart, the United States and the People's Republic of China share many of the same challenges in the delivery of health care to their citizens. Both healthcare systems suffer from inefficiencies, ever-increasing costs, and inequities in access to care. Public health surveillance and response are challenges for both countries, individually and in dealing with global outbreaks. The governments of both countries are taking actions to address their nations' healthcare problems, and they see information technology as a remedy for their healthcare ills - in particular, advanced networking, Electronic health record systems, and mobile computing devices. However, a number of challenges must be met before pervasive, quality health care enabled through technology can be realized. Meeting these challenges presents a good opportunity for China and the U.S. to work together toward effective IT solutions.
美国和中华人民共和国虽然相距半个地球,但在向其公民提供医疗保健方面面临着许多相同的挑战。这两个医疗保健系统都存在效率低下、成本不断增加和获得医疗服务不公平的问题。公共卫生监测和应对是两国各自以及在应对全球疫情方面面临的挑战。两国政府都在采取行动解决各自国家的医疗保健问题,他们认为信息技术是解决医疗保健问题的良方——特别是先进的网络、电子医疗记录系统和移动计算设备。然而,在通过技术实现普及、高质量的医疗保健之前,必须克服一些挑战。应对这些挑战为中国和美国共同努力寻求有效的IT解决方案提供了一个很好的机会。

A mediation framework for Web services in a distributed healthcare information system 分布式医疗保健信息系统中Web服务的中介框架
M. Mrissa, D. Benslimane, C. Ghedira, Z. Maamar
Conceptualizing distributed healthcare information system is an important step toward the enhancement of clinical decision support system. In this paper, we propose a semantic mediation of Web services interfaces for distributed healthcare system. Our proposal is an approach based on Web services technology and their mediation in a peer to peer environment. This approach constitutes the foundation for the set-up of a mediation framework built around the JXTA P2P architecture applied to cardiology domain in collaboration with the National Institute of Health and Medical Research (INSER ERM107). To achieve our goal, we used the OWL-S language as a means of describing semantics of Web services interfaces and the JXTA distributed architecture.
提出分布式医疗信息系统的概念是加强临床决策支持系统建设的重要一步。本文提出了一种面向分布式医疗保健系统的Web服务接口的语义中介。我们的建议是一种基于Web服务技术及其在点对点环境中的中介的方法。这种方法构成了与国家卫生和医学研究所(INSER ERM107)合作,围绕应用于心脏病学领域的JXTA P2P架构建立中介框架的基础。为了实现我们的目标,我们使用OWL-S语言作为描述Web服务接口和JXTA分布式体系结构语义的方法。

Most countries face today a growing burden of chronical diseases. In France the multi-source information system MSIS/spl I.bar/REIN has been built to collect and analyse epidemiological data about end-stage renal diseases, dialysis and kidney transplant. It enables a better knowledge of the demand and of the needs for care. This system is patient-centred and based on a regional organization. With the support of the European Commission, the actors of the French experiment are setting up a similar system in Shanghai, albeit fully adapted to Chinese medical needs and administrative context. The design and the implementation of the system, named Gennere, have put emphasis on its genericity in order to enable the system to be easily adapted to other chronic diseases and/or other countries. The first experiment deals with two fields: nephrology and rheumatology.
今天,大多数国家面临着日益加重的慢性病负担。在法国,建立了多源信息系统MSIS/spl I.bar/REIN,以收集和分析关于终末期肾病、透析和肾移植的流行病学数据。它使人们能够更好地了解对护理的需求和需要。该系统以病人为中心,以一个区域组织为基础。在欧盟委员会的支持下,法国实验的参与者正在上海建立一个类似的系统,尽管完全适应中国的医疗需求和行政环境。该系统名为Gennere,其设计和实施强调其通用性,以便使该系统易于适应其他慢性疾病和/或其他国家。第一个实验涉及两个领域:肾脏病学和风湿病学。
