SCP-ECG and Vital Signs Information Representation--two examples of successful transcontinental cooperation in medical informatics standardization.

During the past 2-3 decades, development work on Medical Devices focused on improving their functionality (device control, signal analysis, pattern recognition and classification). At present, the dominant user requirement is information integration. This requires interconnectivity and interoperability of devices and device systems. Today, due to all major manufacturers operating globally, this requirement can only be met if standards with global relevance are developed. The first standard discussed is the Standard Communications Protocol for Computerized Electrocardiography (SCP ECG). The rapid finalization of the standards document itself was possible due to some of the experts being involved on basic problems for greater than 10 years. Their knowledge and long standing cooperation contributed significantly to a fast consensus finding process as well as quick implementation. The second standard discussed in this paper deals with Vital Signs Information Representation. Before starting to write the document, an International inventory workshop was held to document the state of the technology and of user requirements. This common base of problem understanding makes consensus finding less difficult. Continuous cooperation between the IEEE P1073 group and the CEN/TC251 WG5 project team also ensures early harmonization of the related standards. Finally, early implementation projects in Europe and the US allow verification and modifications based on feed-back from practical experience.

Medical informatics training programme to support the Romanian health care management information system.

The Health Management Information System (HMIS) project initiated by the Romanian Ministry of Health as a component of the healthcare reform is aiming to ensure the technical, functional and operative support for: (i) a better overview of the population health status, of the medical care needs and of the Health System performances; (ii) the improvement of the resource allocation and consumption; and (iii) reform support. This system is supposed to assure a better information flow from the lower to the upper levels of the healthcare network by help of a modern IT support. In the first development stage the system is planned to link the Ministry of Health with the 41 District Health Authorities (DHAs) and with more than 200 pilot health units. The implementation of such a large system raises serious problems of acceptability and a thorough training programme for both technical staff and end users must be considered in order to face this challenge.

Surgical informatics on the Internet: any improvement?

PURPOSE: The Internet is a popular, but ungoverned, source of medical information. This study tracked the change in performance of commonly available search engines and the quality of medical data therein over a four-year period. METHODS: We compared the accuracy of information on a commonly performed surgical procedure (vasectomy) using six standard search engines in a four-year period and with two recently developed search engines. The top 25 ranked sites cited by each search engine were scored for description of the procedure, post-operative instructions, complications and unproven associations. RESULTS: There was no improvement in quality of individual sites over the study period. Additionally, the hit rate of search engines remained poor with 27 sites cited (40%) in 2002 either irrelevant or unavailable. DISCUSSION: Few useful sites with accurate information on surgical procedures are available on the Internet and simple search strategies fail to identify site quality or relevancy. CONCLUSION: At present, the Internet cannot be recommended as a reliable resource for many aspects of health information for patients. The onus is on health-care providers to provide high quality sites and direct patients to these sources of reliable information

Measuring agreement in medical informatics reliability studies.

Agreement measures are used frequently in reliability studies that involve categorical data. Simple measures like observed agreement and specific agreement can reveal a good deal about the sample. Chance-corrected agreement in the form of the kappa statistic is used frequently based on its correspondence to an intraclass correlation coefficient and the ease of calculating it, but its magnitude depends on the tasks and categories in the experiment. It is helpful to separate the components of disagreement when the goal is to improve the reliability of an instrument or of the raters. Approaches based on modeling the decision making process can be helpful here, including tetrachoric correlation, polychoric correlation, latent trait models, and latent class models. Decision making models can also be used to better understand the behavior of different agreement metrics. For example, if the observed prevalence of responses in one of two available categories is low, then there is insufficient information in the sample to judge raters' ability to discriminate cases, and kappa may underestimate the true agreement and observed agreement may overestimate it.

Ethical issues in public health informatics: implications for system design when sharing geographic information.

Public health programs today constitute a multi-professional inter-organizational environment, where both health service and other organizations are involved. Developing information systems, including the IT security measures needed to suit this complex context, is a challenge. To ensure that all involved organizations work together towards a common goal, i.e., promotion of health, an intuitive strategy would be to share information freely in these programs. However, in practice it is seldom possible to realize this ideal scenario. One reason may be that ethical issues are often ignored in the system development process. This investigation uses case study methods to explore ethical obstacles originating in the shared use of geographic health information in public health programs and how this affects the design of information systems. Concerns involving confidentiality caused by geographically referenced health information and influences of professional and organizational codes are discussed. The experience presented shows that disregard of ethical issues can result in a prolonged development process for public health information systems. Finally, a theoretical model of design issues based on the case study results is presented.

The Blue Obelisk-interoperability in chemical informatics.

The Blue Obelisk Movement (http://www.blueobelisk.org/) is the name used by a diverse Internet group promoting reusable chemistry via open source software development, consistent and complimentary chemoinformatics research, open data, and open standards. We outline recent examples of cooperation in the Blue Obelisk group: a shared dictionary of algorithms and implementations in chemoinformatics algorithms drawing from our various software projects; a shared repository of chemoinformatics data including elemental properties, atomic radii, isotopes, atom typing rules, and so forth; and Web services for the platform-independent use of chemoinformatics programs.

VEGA--an open platform to develop chemo-bio-informatics applications, using plug-in architecture and script programming.

In this paper we present the expandability and flexibility features of the VEGA program (downloadable free of charge at http://www.ddl.unimi.it), for the development of custom applications, using it as a multipurpose graphical environment. VEGA can be customized using both plug-in architecture and script programming. The first is useful to add new features and functions, using homemade routines, written with the VEGA Plug-in Development Kit (SDK). With the second approach it is possible to design scripts in VEGA, using the REBOL language, in order to (1) add new functions or customize existing ones; (2) automate common procedures; and (3) allow network communications, by creating a bridge between VEGA and other applications (or other PCs) through the TCP/IP protocol.

Delivery of health informatics education and training.

An overview is provided of education and training in health information management in the context of national information strategies. Although the article focuses upon British programmes, there are examples from North America, Australasia and other countries. Reference is made to international activities in the development of generic courses for education and training, the need for education and training, the content of courses, and methods of delivery, including Internet-based training and education. Governments and health authorities in many countries have recognized the urgent need for a highly educated and trained workforce in information management, but universities have been slow to respond, until the last few years. However, there is now a plethora of education and training programmes in North America, most European countries, and Australasia.

Evaluation of distance learning delivery of health information management and health informatics programmes: a UK perspective.

The aim of the article is to review evaluations of distance learning programmes in health information management, in order to identify the critical success factors for such programmes and discuss future directions. The emphasis is on the UK experience, based partly on reflections on the experience of one programme at University of Wales Aberystwyth (now over 10 years old), and partly on a policy review conducted for the NHS Information Authority and the NHS Information Policy Unit. The methods are, as far as possible, those of a systematic review of existing research, with, additionally, an overview of relevant policy developments for lifelong learning. The topics covered include the aims, objectives and educational philosophies of the programmes. The evidence, combined with the UWA experience, indicates the importance of face-to-face interaction, to complement distance or virtual learning. A student-centred approach to curriculum design and delivery is essential.
