Despite the fact that nursing informatics is entering its third decade as a specialty within nursing, many definitions still exist to describe the field. This paper offers a rationale for a definition for nursing informatics and a critical analysis of past definitions. An organizing framework of technology-oriented, conceptual, and role-oriented definitions is used to critique these definitions. Subsequently, a revised definition is proposed. This evolutionary definition integrates critical concepts from [...]

A comprehensive data warehouse framework is needed, which encompasses imaging and non-imaging information in supporting disease management and research. The authors propose such a framework, describe general design principles and system architecture, and illustrate a multimodality neuroimaging data warehouse system implemented for clinical epilepsy research. The data warehouse system is built on top of a picture archiving and communication system (PACS) environment and applies an iterative object-oriented analysis and design [...]

Problems involving drug knowledge are one of the most common causes of serious medication errors. Although the information that clinicians need is often available somewhere, retrieving it expeditiously has been problematic. At the same time, clinicians are faced with an ever-expanding pharmacology knowledge base. Recently, point-of-care technology has become more widely available and more practical with the advent of handheld, or palmtop, computing. Therefore, the authors evaluated the clinical contribution [...]

The authors developed a novel feature in their clinical information systems, which allows clinicians to request notification about laboratory results. Clinicians who are expecting a particular laboratory result for a particular patient can request a report of the result via an alphanumeric pager as soon as the result is filed into the patient database. This feature has gained popularity and is heavily used in both inpatient and outpatient settings, at [...]

Electronic communication among clinicians and patients is becoming an essential part of medical practice. Evaluation and selection of these electronic systems, called personal clinical electronic communication (PCEC) systems, can be a difficult task in institutions that have no prior experience with such systems. It is particularly difficult in the clinical context. To directly address this point, the authors consulted a group of potential users affiliated with a nationally recognized telemedicine [...]

The Human Brain Project consortium continues to struggle with effective sharing of tools. To facilitate reuse of its tools, the Stanford Psychiatry Neuroimaging Laboratory (SPNL) has developed BrainImageJ, a new software framework in Java. The framework consists of two components-a set of four programming interfaces and an application front end. The four interfaces define extension pathways for new data models, file loaders and savers, algorithms, and visualization tools. Any Java [...]

To explore the feasibility of using the National Library of Medicine's Unified Medical Language System (UMLS) Metathesaurus as the basis for a computational strategy to identify concepts in medical narrative text preparatory to indexing. To quantitatively evaluate this strategy in terms of true positives, false positives (spuriously identified concepts) and false negatives (concepts missed by the identification process).

To evaluate Watch, Discover, Think and Act (WDTA), a theory-based application of CD-ROM educational technology for pediatric asthma self-management education.

Analysis of brain ultrastructure is needed to reveal how neurons communicate with one another via synapses and how disease processes alter this communication. In the past, such analyses have usually been based on single or paired sections obtained by electron microscopy. Reconstruction from multiple serial sections provides a much needed, richer representation of the three-dimensional organization of the brain. This paper introduces a new reconstruction system and new methods for [...]
