Training medics, medical students, nurses, and residents to perform trauma care skills presents many obstacles. These include: emergent nature of the procedures, instructor time, availability of clinical material, and anatomic knowledge. Virtual Reality simulators address each of these obstacles. ⋯ Commercial VR simulators to teach trauma skills include: CathSim Intravenous Simulator (HT Medical), UltraSim Ultrasound Simulator (MedSim), Limb Trauma Simulator (Musculographics/BDI), and the Human Patient Simulator (MedSim). Additionally, we have developed two additional simulators based on the HT CathSim; these are the pericardiocentesis simulator and the diagnostic peritoneal lavage simulator. Future applications include virtual environment triage simulation and surgical airway simulators.

Implementing telehealth applications represents a substantial investment of resources, which is one reason why success is of great interest. Many research and evaluation studies have investigated measures of successful telehealth systems. However, the term "telehealth" represents a wide range of variables including clinical application, characteristics of the information being transmitted, temporal relationships of data transfer and the organizational context. ⋯ Less is known about the relationship among these variables and whether the findings around one variable are generalizable to other settings or applications. For example, organizational support may be essential for successful provider-patient interactions via videoconference, which result in higher quality of life. A conceptual framework would assist in accumulating this type of evidence and supporting more advanced research efforts.

Sharable computer-based clinical practice guidelines: rationale, obstacles, approaches, and prospects.
Clinical practice guideline automation at the point of care is of growing interest, yet most guidelines are authored in unstructured narrative form. Computer-based execution depends on a formal structured representation, and also faces a number of other challenges at all stages of the guideline lifecycle: modeling, authoring, dissemination, implementation, and update. This is because of the multiplicity of conceptual models, authoring tools, authoring approaches, intended applications, implementation platforms, and local interface requirements and operational constraints. ⋯ Because of limitations in what can be done by a single team with finite resources, however, and the variety of additional perspectives that need to be accommodated, the InterMed team has determined that further development of a shared representation would be best served as an open process in which the world community is engaged. Under the auspices of the HL7 Decision Support Technical Committee, a GLIF Special Interest Group has been established, which is intended to be a forum for collaborative refinement and extension of a standard representation that can support the needs of the guideline lifecycle. Significant areas for future work will need to include demonstrations of effective means for incorporating guide-lines at point of care, reconciliation of functional requirements of different models and identification of those most important for supporting practical implementation, im-proved means for authoring and management of complexity, and methods for automatically analyzing and validating syntax, semantics, and logical consistency of guidelines.

Design of a consumer health record for supporting the patient-centered management of chronic diseases.
This paper describes and discusses the design and usage of a shareable consumer health record system to investigate whether these systems can assist in the management of chronic diseases. This web-based system that can be used both by care providers and patients contains medical and patient information, provides access to websites that contain quality information, provides guideline-based advice, allows discussion between patients and allows us to interrogate both patients and care providers on a regular basis in order to get a good impression of the utility of such a consumer record for both chronic patients and the physicians and nurses. A health record system that was developed for the area of Diabetes is presented as an example.
