The role of XML in medical informatics in Hungary.

Reforms in healthcare means frequent changes. The author focusing on flexible information systems and data structures in healthcare, that gives the chance to avoid costly deadlocks, incompatibilities and data chaos--keeping the financial and administrative burden of provider and reimbursement information systems at low level. He describes data and document exchange among health care providers (hospitals, GPs etc.) and the reimbursing insurance institute introducing XML (eXtensible Markup Language) technology and it's multimedia extension called SMIL (Synchronized Multimedia Integration Language) that well supports large textual and multimedia nature of data in healthcare. He presents the most frequent XML datasets for reimbursement in Hungary, the validation schemas (Data Type Definitions) and procedures, comparing the new and old data file sizes with different compressions. The comparison includes different schema file sizes, and validation times.

Activity theory and medical informatics: usability, utility, and copability.

Working with health care today also means working with IT-systems. 'Human Factors' or 'user-friendly design' has been renowned as key factors for the development of safe and successful systems in many industries, not least in the IT-business. Likewise in the computerization of health care, the concepts of 'usefulness' and 'usability' will become key issues in the daily life (and death) in health care context at hospitals, at the GP's office, and in the home of the patient. Though it is a pressing problem, the literature is still very scarce on how to meet this challenge. Inspired by activity theory, this paper sets out to coin a term for an important way to ask questions when determining the usefulness of a medical IT-system. We normally ask two types of questions: 'How usable is the system?' (usability), and 'How functional is the system?' (utility). But most important, we will also have to ask: 'How well does the user cope with the new situation?' As a concept for the latter way of asking questions, we will suggest the term 'copability'.
