The authors' goal was to determine whether dynamic categorization, a new technique for organizing search results, is more useful than the two existing organizational techniques: relevance ranking and clustering. They define a useful tool as one that helps users learn about the kinds of information that pertain to their query, find answers to their questions efficiently and easily, and feel satisfied with their search experience.

To evaluate the performance of a natural language processing system in extracting pneumonia-related concepts from chest x-ray reports.

To create "extensional definitions" of laboratory codes from derived characteristics of coded values in a clinical database and then use these definitions in the automated mapping of codes between disparate facilities.

To assess the effects of a computer-based patient record system on human cognition. Computer-based patient record systems can be considered "cognitive artifacts," which shape the way in which health care workers obtain, organize, and reason with knowledge.

The development of integrated health care systems, the building of distributed computer networks throughout them, and the advent of easy-to-use electronic medical records for ambulatory practices combine to create a powerful argument for an enterprise electronic medical record. Potential customers need to learn from both successes and failures. Although the author could find in the literature only two reports of failures, a survey of family practice residencies revealed ten programs [...]

This review examines how a "bottom-up" model of a civilian technology program works by recounting the story of the "genesis" of the Information Infrastructure for Healthcare (IIH) focused program of the Advanced Technology Program. The IIH program began with an exchange of ideas among members of the private and public sectors (through the submission of "white papers" by members of industry, workshops conducted by the ATP, and meetings among persons [...]

Health care leaders emphasize the need to include information technology and informatics concepts in formal education programs, yet integration of informatics into health educational programs has progressed slowly. The AMIA 1999 Spring Congress was held to address informatics educational issues across health professions, including the educational needs in the various health professions, goals for health informatics education, and implementation strategies to achieve these goals. This paper presents the results from [...]

Nursing Vocabulary Summit participants were challenged to consider whether reference terminology and information models might be a way to move toward better capture of data in electronic medical records. A requirement of such reference models is fidelity to representations of domain knowledge. This article discusses embedded structures in three different approaches to organizing domain knowledge: scientific reasoning, expertise, and standardized nursing languages. The concept of pressure ulcer is presented as [...]

The purpose of this study was to test the adequacy of the Clinical LOINC (Logical Observation Identifiers, Names, and Codes) semantic structure as a terminology model for standardized assessment measures.
