1.  Computer-Based Exercises in Cardiac Diagnosis (PlanAlyzer) 
We are developing a microcomputer-based system that incorporates text, hypertext, images, and critiquing theory to instruct medical students in the appropriate evaluation of patients with chest pain. The developmental system is now in its formative evaluation; field trials begin in Fall 1988. In this paper the planning, technical issues, and instructional design are discussed.

2.  Findings from an evaluation of PlanAlyzer's double cross-over trials of computer-based, self-paced, case-based programs in anemia and chest pain diagnosis. 
We report on three years of research trials of the PlanAlyzer I Project--a carefully controlled research study using a microcomputer-based, self-paced, case-based, event-driven system for medical education. PlanAlyzer presents cases, elicits and critiques a second year student's approach to the diagnosis of anemias and chest pain. PlanAlyzer uses text, hypertext, images and critiquing theory. Students were randomized, one half becoming the experimental group who received the interactive PlanAlyzer cases in anemia, the other half becoming the controls who received the exact same content material in a text format. Later in each year there was a crossover, the controls becoming the experimentals for a similar intervention with the cardiology PlanAlyzer cases. Results at the end of the first two years of trials show that the programs have achieved some significant efficiency and economy gains. 96 faculty hours of classroom time were saved by using PlanAlyzer in their place, with no loss in student achievement. In terms of student proficiency and efficiency, combining the anemia and cardiology trials, the 328 students in the two years of full scale trials were able to accomplish the project's instructional objectives. The experimentals accomplished this in 43% less time than the controls. On the average, for both the anemia and chest pain programs, this amounted to students spending 7.5 hours longer on the 30 text cases than on the same 30 computer cases to achieve the same level of mastery. There have been no significant proficiency differences (as measured by current post-tests) between the experimental and control groups.(ABSTRACT TRUNCATED AT 250 WORDS)

4.  Fatal encephalitis and myocarditis in young domestic geese (Anser anser domesticus) caused by West Nile virus. 
Emerging Infectious Diseases  2001;7(4):751-753.
During 1999 and 2000, a disease outbreak of West Nile (WN) virus occurred in humans, horses, and wild and zoological birds in the northeastern USA. In our experiments, WN virus infection of young domestic geese (Anser anser domesticus) caused depression, weight loss, torticollis, opisthotonus, and death with accompanying encephalitis and myocarditis. Based on this experimental study and a field outbreak in Israel, WN virus is a disease threat to young goslings and viremia levels are potentially sufficient to infect mosquitoes and transmit WN virus to other animal species.

5.  Designing medical informatics research and library--resource projects to increase what is learned. 
Careful study of medical informatics research and library-resource projects is necessary to increase the productivity of the research and development enterprise. Medical informatics research projects can present unique problems with respect to evaluation. It is not always possible to adapt directly the evaluation methods that are commonly employed in the natural and social sciences. Problems in evaluating medical informatics projects may be overcome by formulating system development work in terms of a testable hypothesis; subdividing complex projects into modules, each of which can be developed, tested and evaluated rigorously; and utilizing qualitative studies in situations where more definitive quantitative studies are impractical.

7.  Analysis, requirements and development of a collaborative social and medical services data model. 
In any medical and social service setting, patient data must be readily shared among multiple providers for delivery of expeditious, quality care. This paper describes the development and implementation of a generalized social and medical services data model for an ambulatory population. The model, part of the Collaborative Social and Medical Services System Project, is based on the data needs of the Baylor College of Medicine Teen Health Clinics and follows the guidelines of the ANSI HISPP/MSDS JWG for a Common Data Model. Design details were determined by informal staff interviews, operational observations, and examination of clinic guidelines and forms. The social and medical services data model is implemented using object-oriented data modeling techniques and will be implemented in C++ using an Object-Oriented Database Management System.

8.  The development of a client application for the collaborative social and medical services system. 
This paper describes the design and implementation of a client application for the Baylor College of Medicine Teen Health Clinics. The application is the front end to the Collaborative Social and Medical Services System (CSMSS) under development by Baylor's Medical Informatics and Computing Research Program [8]. The application provides distributed access to an underlying object oriented database system. A process driven and patient centered design will provide staff members with a complete set of services, including forms for data entry and viewing, query, and access management to facilitate efficient and effective delivery of services. Role-specific interfaces will be supplied for clerks, nurses, nurse practitioners, physicians, and social workers. The client application is being designed using object oriented methodologies and technologies with the C++ programming language, and will operate within a Microsoft Windows operating environment utilizing Object Linking and Embedding for application interoperability.

9.  The development of a data security model for the Collaborative Social and Medical Services System. 
This paper presents the development of the Collaborative Social and Medical Services System's (CSMSS) data security mechanism. This mechanism was synthesized from an analysis of the CSMSS problem domain, and from a study of the methods used by modern operating systems and database management systems. The resulting mechanism is more flexible and expressive than traditional access control methods and is generally applicable to the management of privacy and multi-provider access.

10.  The CIO and the medical informaticist: alliance for progress. 
To achieve the full potential of information technology, health care institutions must overcome organizational and political barriers that often overshadow scientific and technical barriers. The time has come for an alliance between the Chief Information Officer (CIO) and medical informatics specialists, or informaticists. Organizations that successfully accomplish this alliance will position themselves to take advantage of the enormous potential of information technology to manage today's cost-quality pressures. This article first reviews some of the recent developments in the way health care organizations manage information technology. It then describes the traditional, perhaps the natural state of affairs, in which there may be tension and conflict between medical informaticists and line managers of information systems (IS). Finally, the article makes a case for closer collaboration and cooperation between these groups, and provides a case study that illustrates one example of such an alliance.

11.  A systems approach to planning biomedical information services. 
A systems approach to planning was applied within the Biomedical Information Communication Center at Oregon Health Sciences University when its User Services division launched a strategic planning effort. By looking at the choice subsystem, the organizational structure, and the behavioral subsystem, those engaged in planning attempted to assure that desired change would permeate the entire system. The challenge of applying a theoretically ideal planning model within an environment averse to planning is delineated.
