Extensions to the HISA standard--the SynEx computing environment.

OBJECTIVES: This paper reports on the integration work required to support the delivery of healthcare. Specifically, four elements are included being: the DHE (a standards based distributed healthcare environment), Synapses which is a patient record server, XML as a technology to deliver records, and finally two client applications that facilitate structured data entry (SDE) and the remote booking of specialist services. METHODS: A general motivation for the work is presented and augmented on hand of a clinical scenario. Additionally, the adoption of a middleware approach is reviewed. The role of computerised patient records is described followed by an account of a federated record server. The approach favoured by standards bodies in utilising XML is covered and the tailoring to suit the needs of the integration is explained. The main practical challenges in achieving integration are presented, one of these being the mapping between the DHE data model and the Synapses server record architecture. RESULTS: The described environment has been demonstrated to provide the functionality that is required and in addition it has been shown that the engineering challenges can be met in a controlled and orderly manner. CONCLUSIONS: The role of the DHE middleware component acting as an 'anchor' has been shown to be a valid one onto which other specialised components can be added to provide a richer service environment. Additionally, it has been demonstrated that XML is a good candidate technology that facilitates connectivity to client applications over an extranet. The demands inherent in both the clinical scenario and the computerised patient record can be met by the computing environment described in the paper.

Purposes of health identification cards and role of a secure access platform (Be-Health) in Belgium.

Although other alternatives may exist, identification cards have been chosen as an acceptable and adequate tool to be used to identify patients and health professionals. It is planned to use these for digital signature and for access to electronic health records: for searching various databases as well as for health information exchange. Local applications might exist independently, but the Belgian federal state has now developed Be-Health, a platform for health professionals, social security personnel and the general public, designed to facilitate a secure common uniform access to certain health data.

A process view of medical practice by modeling communicative acts.

The need of an electronic patient record with a process view on medical care is widely acknowledged. Characteristics of DEMO (Dynamic Essential Modeling of Organizations) suggest that with this methodology an adequate process view of medical practice can be obtained. In applying DEMO to the care process of the emergency department at the University Medical Centre Utrecht, it was investigated if DEMO fulfilled our expectations. This practical application showed that DEMO yields an adequate process view by a clear and comprehensible view of the core processes, responsibilities, co-ordination of activities, and a clear description of causal and conditional relations between activities.

Wireless technology infrastructures for authentication of patients: PKI that rings.

As the public interest in consumer-driven electronic health care applications rises, so do concerns about the privacy and security of these applications. Achieving a balance between providing the necessary security while promoting user acceptance is a major obstacle in large-scale deployment of applications such as personal health records (PHRs). Robust and reliable forms of authentication are needed for PHRs, as the record will often contain sensitive and protected health information, including the patient's own annotations. Since the health care industry per se is unlikely to succeed at single-handedly developing and deploying a large scale, national authentication infrastructure, it makes sense to leverage existing hardware, software, and networks. This report proposes a new model for authentication of users to health care information applications, leveraging wireless mobile devices. Cell phones are widely distributed, have high user acceptance, and offer advanced security protocols. The authors propose harnessing this technology for the strong authentication of individuals by creating a registration authority and an authentication service, and examine the problems and promise of such a system.

Technology integration: a journey, not a destination.

This article discusses the integration of the latest technologies into the dental practice. Given the rapid rate of obsolescence in computer hardware, clinicians need to look to practice-management software to build the foundation for incorporating all future applications into a smoothly running operation. Combined, the core components of the clinical dental record, digital radiography, intraoral and digital cameras, and cosmetic imaging create an integrated dental image-management system that is becoming a critical factor in how we communicate with our patients and with each other.

Medcast: evaluation of an intelligent pull technology to support the information needs of physicians.

This study reports the initial results of an evaluation of Medcast, a commercial medical information service that uses intelligent pull technology to deliver medical information to practicing physicians. Medical news, CME, and other information are transferred by modem nightly to the physician's computers where this information can be accessed at a convenient time. A survey was faxed to 195 subscribers to the system. A total of 73 (39%) responded. The results indicate that prior to implementation of the Medcast system, almost 40 percent of the respondents did not use their computers for professional activities because of time constraints, costs and computer literacy problems. After implementation of Medcast, almost 70 percent of the respondents used the system two or more hours per week. Ninety percent of the respondents felt that use of the system has enhanced their practice. These findings have important implications for future efforts to implement medical informatics applications to support the information needs of practicing physicians. Experience with intelligent pull technology that is relatively easy to use may be a good way to break down attitudes and barriers to the use of computer systems to support clinical practice and may prepare physicians for a wider use of the Internet to support their future information needs.

The PRIDEH project: taking up privacy protection services in eHealth.

PRIDEH (Privacy Enhancement in Data Management in e-Health) is a project that runs for two years and is partly funded by the European Commission. The focus of PRIDEH is on the stimulation of the take-up of privacy enhancing technologies within the health domain. Privacy enhancing technologies build upon available cryptographic and communication technologies. The concept of privacy enhancing services delivery through the use of intermediary trusted third parties has already been described in literature but rarely turned into practice. A number of limited PET (Privacy Enhancing Technologies) applications exist in closed domains. The very few existing solutions are not based on an independent TTP (Trusted Third Party) concept which renders their trustworthiness questionable. PRIDEH wants to enhance the take-up of PET delivery based on sound TTP principles in the domain of healthcare.

Integrating specialized application systems into hospital information systems--obstacles and factors for success.

Hospital information systems are often huge and heterogeneous systems. To support physicians with their daily clinical work, application systems are developed which are dedicated to particular medical fields or tasks and which have to be integrated into the hospital information system. The integration process is quite complicated, because it makes the information system's infrastructure even more heterogeneous. We developed an application system for documentation and therapy planning in pediatric oncology (DOSPO) and we started to introduce it into the Department of Pediatric Oncology of Heidelberg University Hospital. The fact that DOSPO is developed as a universal system for nationwide use made the integration process more difficult. In any case, the introduction of specialized application systems has to be planned systematically in advance, regarding the prevailing information system's infrastructure, available resources and established processes. To simplify the integration process comprehensive electronic patient records for the future should be designed in a way that they can be enhanced easily by new clinical functions.

Telematics and protocols of care in critical care environments.

The paper discusses the potential roles for protocols of care within critical care environments from the perspective of providing real-time support for their application. The discussion is based around a conceptual model of care in critical care environments. This model has been developed in the wider context of developing information technology systems to support clinical care in critical care environments. The conceptual model of care is a three layer model which demonstrates both the hierarchical and temporal aspects of the care delivered to patients. It is proposed that if the value of protocols of care is to be realised in critical care environments then they must be seamlessly integrated into the routine data management associated with the care of patients. In order to demonstrate this and to evaluate the utility of this concept in the clinical environment, the systems from the AIM TANIT (Telematics in Anaesthesia and Intensive Therapy) project have been used as prototype platforms. The application of the concepts developed are described in two critical care environments: the anaesthesia department and the intensive care unit. Problems in using protocols of care in intensive care units suggest that integrating these with a problem solving methodology to create an integrated care plan may be a more appropriate approach to patient management.

Finnish health telematics approach for patient centric care.

It was to be expected that questions concerning the implementation of new technology were to arise in many respects. Nowadays hospitals cannot function effectively and profitably without medical technology equipment like magnetic resonance imaging devices, computerised tomography and ultrasound equipment or automatic laboratory analytic. The status of information technology is different. Although substantial advances have been achieved in medical technology in healthcare we are still far from taking full advantage of the potential of new services in information technology in real life in the hospitals and health centres. Products and services are still hard and difficult to use and out of reach for many professionals and people especially in rural regions. One of the problems prohibiting healthcare professional to move real e-work environment is the complexity of IT-applications and the price levels of those applications. The most important stakeholder is the consumer, currently at the periphery of the debate but beginning to move from the periphery to the centre, where the consumer's demands will be better heard--and perhaps even met. The dilemma for government, managers, health insures and health professionals, though, is that consumers demands and health gain are not always ad idem. What is the optimum relationship between government, healthcare professionals and consumers accountable and what factors will eventually change the relationship?

Medical expert systems--knowledge tools for physicians.

Recent advances in the field of artificial intelligence have led to the emergence of expert systems, computational tools designed to capture and make available the knowledge of experts in a field. Although much of the underlying technology available today is derived from basic research on biomedical advice systems during the 1970s, medical application packages are thus far generally unavailable from the young artificial intelligence industry. Medical expert systems will begin to appear, however, as researchers in medical artificial intelligence continue to make progress in key areas such as knowledge acquisition, model-based reasoning and system integration for clinical environments. It is accordingly important for physicians to understand the current state of such research and the theoretic and logistic barriers that remain before useful systems can be made available. One experimental system, ONCOCIN, provides a glimpse of the kinds of knowledge-based tools that will someday be available to physicians.

Integrating users' activity analysis in the design and assessment of medical software applications: the example of anesthesia.

As the computers become more and more and aid for the management of medical information, some specialists like anesthetists demand specialized applications to support their own activity. Usually, these applications are developed following a Users' Requirements analysis and functional specifications. We demonstrate here that when the management of medical information is closely intertwined with the physician's activity, it is also necessary to perform a precise ergonomics analysis of this activity in order to identify the cognitive and organizational constraints that affect the usability and acceptance of the tool. We report here the results of such an analysis for the pre-operative anesthetic consultation, and illustrate this analysis with the evaluation of a computerized anesthetic record.
