Privacy and efficiency in patients focused health care processes.
Today's health care industry is striving to achieve the development and deployment of computer-based patient records for improvements in health care quality, cost, and access. This rapidly increasing use of computer techniques in the field of medicine and health care has created an urgent need for the dissemination of information on data protection. We present in this paper a workflow-based approach to ensure privacy and efficiency in clinical information systems and discuss the presented solution according to its practicability in daily clinical use.

Since the mid 1980s, paper clinical pathways have been used in defining the road map of patient care. They have been used with varying degree of success for providing more cost-effective healthcare and helped to establish quality improvement models for healthcare delivery. Many attempts have been made to produce electronic versions of the paper clinical pathways in order to maximise benefits of the paper based systems. ⋯ A state-transition information model (STIM) grounded in the Object Oriented system design paradigm is used to reconceptualise a computerised clinical pathways design. A computerised clinical pathways prototype is currently being developed based on this STIM model. The prototype will demonstrate improved functionality: better information management and decision support capabilities.

Review Comparative StudyAssessment of trabecular structure using high resolution magnetic resonance imaging.
Although bone mineral density is one of the most important contributing factors to bone strength and risk of fracture, studies have shown that changes in bone quality and structure independent of bone mineral density, influence both bone strength and individual risk of fracture. The influence of these other factors is thought to explain at least partially the observed overlap in bone mineral measurements between patients with and without osteoporotic fractures, irrespective of measurement site or technique. Thus, several new emerging techniques have been aimed at quantifying trabecular bone structure in addition to bone density. ⋯ Quantitative measures of trabecular architecture derived from such images have been compared with those obtained from higher resolution 18 microns images, and with biomechanical properties. In vivo studies in the radius and calcaneus have been performed and differences between osteoporotic and normal subjects are distinguishable. Thus, MR imaging techniques coupled with computerized image analysis may potentially be very useful for studying osteoporosis and quantifying trabecular bone architecture and may provide information in addition to bone density.
