Evaluation as a tool to increase knowledge in healthcare informatics.
The evaluation of information systems is an important topic in Clinical Informatics. It is argued that past evaluations have not been particularly informative in progressing the effective use of IT in healthcare due to their narrow focus. The different roles of evaluation in Clinical Informatics are examined, and the breadth and diversity of the available methodological tool kit highlighted. The aim is to stimulate a greater awareness of the roles and methods of evaluation. Challenges in evaluation which face the Clinical Informatics community are discussed and finally some comments made concerning the way in which evaluation might be made more effective in order to improve our knowledge of how to deliver useful systems into healthcare.

Telematics for clinical guidelines: a conceptual modelling approach.
PRESTIGE is a project for applying telematics to assist the dissemination and application of clinical practice guidelines and protocols. Previous publications have described PRESTIGE's technical approach, including the use of a generic model for representing the knowledge content of clinical guidelines. This approach offers the possibility of 'plug-and-play' electronic distribution of clinical guidelines produced by multiple authoring bodies for use on multiple healthcare clinical management software platforms. A recent joint workshop held with the Section on Medical Informatics, Stanford University School of Medicine compared the European consensus approach developed in PRESTIGE with a parallel series of projects for computer-assisted protocol-based healthcare undertaken at Stanford and other American centres over the past, which confirmed the convergence and complementarity of our approaches, and holds out prospects of world-wide standardization in healthcare protocol knowledge representation. This paper summarises PRESTIGE conceptual model set which is the design of the project's approach.

The place of SGML and HTML in building electronic patient records.
The authors are concerned that, although popular, SGML (Standard Generalized Markup Language) is only one approach to capturing, storing, viewing and exchanging healthcare information and does not provide a suitable paradigm for solving most of the problems associated with paper based patient record systems. Although a discussion of the relative merits of SGML, HTML (HyperText Markup Language) may be interesting, we feel such a discussion is avoiding the real issues associated with the most appropriate way to model, represent, and store electronic patient information in order to solve healthcare problems, and therefore the medical informatics community should firstly concern itself with these issues. The paper substantiates this viewpoint and concludes with some suggestions of how progress can be made.

Protocol-directed shared care in cardiology.
In the new market-oriented UK National Health Service, hospitals succeed or fail on the quality of service they provide to their customers. It is therefore important that institutions like the Royal Brompton Hospital can meet the information and communication needs of General Practitioners and hospitals who use their services so that co-ordination between healthcare professionals involved in the co-operative care of individual patients can be ensured. One method of improving the relationship between healthcare professionals is by the use of consensus-based clinical protocols which define "best practice' co-operative care for a particular condition. The Royal Brompton Hospital has been a clinical partner in the AIM project DILEMMA which has been examining technology and methodologies for applying clinical protocols supported by telematics to general practice and shared care. A detailed requirements analysis has been carried out to look at the problems of shared care in cardiology and this has resulted in a demonstration system being developed to show how protocol-directed shared care and its supporting technology could be implemented to solve real clinical problems. Conclusions have been drawn that concern the use of protocols and information technology generally in routine clinical care.
