Physician order entry is a powerful function of a computerized hospital information system. Although designed to be clinician-driven, the imaging section of the order entry system may not be designed optimally to engage the clinician with imaging procedures logically organized for the clinician's typical work patterns. There also may be resistance among overburdened clinicians in having to take the time to learn a new computer system and to assume "clerk's [...]

Primary care informatics is an emerging academic discipline that remains undefined. The unique nature of primary care necessitates the development of its own informatics discipline. A definition of primary care informatics is proposed, which encompasses the distinctive nature of primary care. The core concepts and theory that should underpin it are described. Primary care informatics is defined as a science and as a subset of health informatics. The proposed definition [...]

The Heart Disease Program (HDP) is a novel computerized diagnosis program incorporating a computer model of cardiovascular physiology. Physicians can enter standard clinical data and receive a differential diagnosis with explanations.

To analyze the effect of expert knowledge on the inductive learning process in creating classifiers for medical text reports.

To investigate the association between clinical team functioning and diffusion (awareness, use, and impact) of a 24-hour online evidence retrieval system. To examine the relationships between clinical team characteristics and the adoption of the online evidence system.

Develop a detailed representation of pharmacokinetics (PK), derived from the information in Summaries of Product Characteristics (SPCs), for use in computerized systems to help practitioners in pharmaco-therapeutic reasoning.

To describe the perceptions of diverse professionals involved in computerized physician order entry (POE) at sites where POE has been successfully implemented and to identify differences between teaching and nonteaching hospitals.

There is scant published experience with implementing complex, multistep computerized practice guidelines for the long-term management of chronic diseases. We have implemented a system for creating, maintaining, and navigating computer-based clinical algorithms integrated with our electronic medical record. This article describes our progress and reports on lessons learned that might guide future work in this field. We discuss issues and obstacles related to choosing and adapting a guideline for electronic [...]

To describe advanced clinical information systems in the context in which they have been implemented and are being used.
