While guideline-based decision support is safety-critical and typically requires human interaction, offline analysis of guideline compliance can be performed to large extent automatically. We examine the possibility of automatic detection of potential non-compliance followed up with (statistical) association mining. Only frequent associations of non-compliance patterns with various patient data are submitted to medical expert for interpretation. The initial experiment was carried out in the domain of hypertension management.

Predicting survival causes after out of hospital cardiac arrest using data mining method.
The prognosis of life for patients with heart failure remains poor. By using data mining methods, the purpose of this study was to evaluate the most important criteria for predicting patient survival and to profile patients to estimate their survival chances together with the most appropriate technique for health care. ⋯ Data mining methods could help clinicians to predict the survival of patients and then adapt their practices accordingly. This work could be carried out for each medical procedure or medical problem and it would become possible to build a decision tree rapidly with the data of a service or a physician. The comparison between classic analysis and data mining analysis showed us the contribution of the data mining method for sorting variables and quickly conclude on the importance or the impact of the data and variables on the criterion of the study. The main limit of the method is knowledge acquisition and the necessity to gather sufficient data to produce a relevant model.

Transforming written guidelines into electronic formats--international perspectives.
The Guidelines International Network (G-1-N www.g-i-n.net) is a major new international initiative involving guideline-developing organisations from around the world. G-I-N seeks to improve the quality of health care by promoting systematic development of clinical practice guidelines and their application into practice. The Network now has over 45 international members, most of whom prepare evidence-based clinical practice guidelines, or actively promote the use of evidence in practice. ⋯ To be effective, there must be formal internationally agreed standards that allow electronic guidelines to be shared and automatically updated. The Guidelines International Network will be taking a leading international role in working with designers and vendors of electronic decision support systems and tools to guarantee the integrity of guidelines when translated into electronic formats. This presentation by Catherine Marshall, Kitty Rosenbrand and Guenter Ollenschlaeger will: --explore current experiences from New Zealand, Germany and the Netherlands --identify issues from the perspective of guideline developers --make recommendations for establishing opportunities for software designers, vendors and informatics experts to collaborate with guideline developers to ensure that up to date evidence can be easily implemented and shared throughout the world.

The MET (Mobile Emergency Triage) system is an m-health application that supports emergency triage of various types of acute pain at the point of care. The system is designed for use in the Emergency Department (ED) of a hospital and to aid physicians in disposition decisions. Given patient's condition, MET recommends a triage by consulting decision rules stored in the system's knowledge base. ⋯ The system facilitates patient-centered service and timely, high quality patient management. It provides recommendations using a limited amount of clinical data, normally available at the point of care. Furthermore, it provides a possibility for the structured evaluation of this data by an attending physician.

Distributed interactive virtual environments for collaborative experiential learning and training independent of distance over Internet2.
Medical knowledge and skills essential for tomorrow's healthcare professionals continue to change faster than ever before creating new demands in medical education. Project TOUCH (Telehealth Outreach for Unified Community Health) has been developing methods to enhance learning by coupling innovations in medical education with advanced technology in high performance computing and next generation Internet2 embedded in virtual reality environments (VRE), artificial intelligence and experiential active learning. Simulations have been used in education and training to allow learners to make mistakes safely in lieu of real-life situations, learn from those mistakes and ultimately improve performance by subsequent avoidance of those mistakes. ⋯ The ability to make mistakes in a safe environment is well received by students and has a positive impact on their understanding, as well as memory of the principles involved in correcting those mistakes. Bringing people together as virtual teams for interactive experiential learning and collaborative training, independent of distance, provides a platform for distributed "just-in-time" training, performance assessment and credentialing. Further validation is necessary to determine the potential value of the distributed VRE in knowledge transfer, improved future performance and should entail training participants to competence in using these tools.
