Health care organizational uses of information technology.

Let's say that, by having read the many inspiring articles on medical informatics in this issue of Physician Executive, you are now ready to move ahead with some serious applications of information systems in your organization. Or, you were already a believer in the usefulness of information technology (IT), and are wondering how to proceed. What types of systems should your organization be looking at to acquire or build? How should you get to there from here? Perhaps you'll find what you're looking for in what follows--an initial roadmap through organizational "IT Land."

Managing the new technical employee.

We live in an age of information. Almost every element of society is dominated by information and the need for information. No person can expect to thrive in the future unless he or she knows and understands information processing, particularly computerized information processing. The growth of medical informatics in the health care field is a further indication of the pervasiveness of the information age. With this technology, however, comes a new and very different cadre of employees. Physician executives who desire to succeed in this new and changing world will have to understand how these employees are different and how management must change to accommodate them. Marilyn Kennedy begins the understanding process in this column.

Education review: diversity and opportunity in health management systems and health information management.

Innovative methods for managing health care information are critical to solving the problems posed by our nation's health care system. The Department of Health Information Sciences at the John G. Rangos, Sr. School of Health Sciences at Duquesne University in Pittsburgh has created baccalaureate and master's degree programs in health management systems that respond to a need for the redesign and management of the cultural and technologic infrastructure necessary to create more efficient, highly effective, and better informed health care organizations.

Research takes on a second life. Interview by John McCornack.

The health care industry is embracing the artificial intelligence concepts that Edward H. Shortliffe, M.D., developed in the 1970s. His current work on Web-based information dissemination may yield applications for the next century.

Security standards for medical information systems.

This paper has provided an overview of some of the aspects of medical information systems security and the standards that are available to implement security solutions. There is a need to address a complete solution for the security of medical information systems: technical, procedural and legal protection of medical records, databases, applications, hardware and software, networks and the management of the system. The existing standards cover some of these topics but not all. There is still room for further work and the development of standardised technological solutions supported by legal and procedural measures.

ASTM E31.15 on health knowledge representation: the Arden Syntax.

ASTM subcommittee E31.15 on Health Knowledge Representation was formed to promote standards for defining and sharing health knowledge bases. Its first standard, the Ardan Syntax, is focused on knowledge bases that can be represented as a set of independent modules called Medical Logic Modules (MLMs). The standard is in clinical use and has generated significant interest in industry and academics. The Extensions task group plans to extend the syntax where appropriate, to expand to other types of knowledge bases. The Validation/Verification task group is approaching the enormous problem of evaluating knowledge bases and the process of sharing them.

Development of standard healthcare EDI messages.

The development of standard healthcare messages requires a full understanding of user needs, an appropriate organisation structure for developing consensus and a suitable methodology. This paper presents the current state of development in the European Standardisation Organisation's Working Group on Healthcare Messages and Communications (CEN TC251 WG3).

Development and current use of ASTM/HL7 messages for health care communications in the USA.

Two influential organizations in the development of medical data exchange standards in the United States of America are ASTM and HL7. A shared message structure has been adapted to diverse applications including hospital information systems and clinical laboratories. The basic approach is the exchange of ASCII messages. Messages segments relate to clinical entities and support a hierarchy of entities. Individual data fields are of variable length and bounded by delimiter characters. The feasibility of this approach has been confirmed by its adoption by a number of medical institutions and information system vendors.

Benefits and threats of new technologies.

In this paper first the effect of new hardware and software technologies on threats to data integrity and usage integrity is considered. Next the potential is considered of new technical facilities for improving the protection. It is concluded that the increasing risks for data and usage integrity are not counter balanced at present by new protection measures. A concerted action is proposed to face this problem. Especially action is proposed to develop methods for quality assurance of software, for access control in networks and to improve data/usage integrity around PC's.

Perspectives on changing times: implications for insurance medicine.

Profound changes are occurring in medicine. These changes are in both medicine itself and also in the economic and social context. The driving forces for change include health care reform, sophisticated consumers, new technology, information explosion and ethics of controlling human biology.
