"Patient informatics": creating new partnerships in medical decision making.

The amassing of health information on the Internet and World Wide Web continues unabated. Patients anxious to participate in decisions about their own treatment have turned to the Internet to confirm diagnoses, validate physician-recommended treatment, or seek alternative therapies. While increased information for patients has been linked to improved outcomes, there are inherent dangers associated with the kind of unauthenticated information available on the Web. The authors discuss the nature of these dangers as well as review the advantages for patients of "information therapy" (improved access to health information). They also examine how the Internet has begun to affect the physician-patient relationship, and describe how the Internet and information technology can be effectively used by physicians in patient care. They recommend that the academic health sciences community seize the opportunity to take the lead in ensuring that patients have access to reliable health information, and suggest that "patient informatics" be integrated by academic physicians and educators into the teaching of clinical skills.

Mathematical formulation for computing the performance of self expanding helical stents.

Stents are cylindrical devices implanted inside pathologic tubular passages within the body. The stents, which are made of metal or plastic, keep the passage open for flow (of blood, urine, air etc.) by applying radial pressure on the passage walls. In most cases the stents are selected empirically for each application. We introduce here a mathematical formula for computing the radial pressure induced by self expanding helical stents. The formula was verified experimentally for an urological stent using a special device. The results correlate well with the theoretical predictions (R = 0.997; y = 1.017 x -0.06 kg; SEE = 0.034, for forces and R = 0.9988; y = 1.04 x +8.7 mmHg; SEE = 25.3 for pressures). This formula can potentially serve as an analytical tool for selecting the most suitable stent for a given application.

Taking a new look at the hosted applications model.

Deciding whether to adopt a hosted applications model for your organization? Advantages--rapid time to value, no hardware and software maintenance responsibilities, reduced IT staff support burden. Disadvantages--reliance on the Internet to deliver applications, concerns about security, and limited customization options with some vendors.

[Applications of the digital network in radiotherapy].

Construction of the digital radiotherapy network is the need of contemporary radiotherapy, and is also an important part of the construction of a modernized hospital. This article analyzes the basic technical requirements and functions of the digital radiotherapy network, and gives opinions on the application of the digital radiotherapy network.

Overcoming information overload: an information system for the primary care physician.

Primary Care Office InSite (PCOI) is a Web-based intranet application that provides ready access to a collection of information useful in primary care. The PCOI Web site was developed by, and is widely used within, the Massachusetts General Hospital (MGH) and its affiliated community practices. Over 1600 users logged 60,000 separate sessions in the past year. The site contains clinical practice guidelines, patient educational material, drug prescription and cost information and referral information, all designed for use during routine patient care activity. A continuing and dynamic collaboration between the users and developers of the system, just-in-time access and a "one-stop portal" to a variety of resources have resulted in a very high approval rating by the users. This paper discusses the important characteristics of the Web site, specific functions that improve the workflow of the practicing clinician, and limitations of the present implementation.

Medicine in virtual environments.

Virtual Environments allow a human to interact with a (computer) system in such a way that a high level of presence in a computer-synthesised world is experienced. In principle, all human senses are involved with the interaction. Many applications may benefit from this type of human-machine interfacing, however, few have emerged so far for medicine. In this paper we elaborate on some realistic potential applications of Virtual Environment technology in the field of medicine. These applications can be found in education/training, therapy, surgery, rehabilitation, diagnosis, telemedicine and biomechanics. The value to be added to these applications by VE technology lies in the fact that patient data or patient models may be moderated to the physician in a more intuitive and natural manner. Despite these potentials, the short-term feasibility of these applications can be put into question for various reasons. Firstly, the current generation of display devices have a resolution that may show to be too low to achieve a sufficiently high degree of realism for medical applications. Secondly, there are no commercially-available actuators for tactile and force feedback which the physician desperately need for the simulation of the contact with the (virtual) patient. Thirdly, the enormous computing power required for these applications (still) needs a considerable investment. With these limitations in mind, we believe that we are at the cradle of a whole new generation of VE applications in medicine.

The digital toolbox for teaching.

Continued improvements in computer technology have led to significant enhancement of clinical teaching. We describe a "digital toolbox" consisting of personally accessible hardware and software products to assist in clinical teaching. The areas covered are computer-assisted diagnosis, digitization and display of clinical materials, archiving of digitized clinical materials, and decision analysis. All products are commercially available, and none require special training or customization for medical teaching application.

Evaluation of health information applications--challenges ahead of us.

OBJECTIVES: The aim of the paper is to review the challenges for evaluation in the light of characteristics of the healthcare sector, present as well as future. METHODS: The approach is a synthesis based on highlights from the literature. RESULTS: The review addresses the following issues: 1) the role of evaluation activities within a systems development or implementation context; 2) suggestions on the nature of success and failure characteristics; and 3) evaluation aspects viewed in the perspective of different types of systems. Constructive evaluation, evaluation being the act of bringing about a decision-making basis, is perceived as the means to minimize failure and maximize success from the very beginning of the development or implementation. Based on these discussions, the challenges that evaluation and evaluators are facing are debated. CONCLUSION: The ultimate challenge ahead is first to fill the gap of presently needed evaluation methods. This need is in particular related to evaluation of cognitive and work process-oriented aspects of IT-based solutions. Finally, the challenge is to provide constructive evaluation methods and methodologies for dealing with the full complexity and dynamics of the target domain, for application within the entire lifecycle of the IT-based systems and solutions.

A development environment to create medical applications.

This paper describes a Development Environment for medical applications developers coupling Reuse and Object-Oriented technologies. It presents the two main phases of the reuse process, the reusable component creation and the reusable component use, and stresses on the very nature of reusable development components. We provide both a classification model for those reusable components that is a support for an efficient and simple retrieval mechanism, and a reusable component model that considers the same way components of large and low-granularity levels (e.g., application frameworks and methods of a given class). The reusable component model is based on the underlying idea that development components are not operational components since they do not have the same purpose. This model first represents each component as an aggregation of other sub-components, together with all information needed for its retrieval (e.g., classification and facets), its understanding (e.g., informal functional description), and its dependencies with other development components, in particular the applications in which it occurs, since applications are considered here as abstract development components.
