OBJECTIVE Computerized Provider Order Entry (CPOE) with electronic documentation, and computerized decision support dramatically changes the information environment of the practicing clinician. Prior work patterns based on paper, verbal exchange, and manual methods are replaced with automated, computerized, and potentially less flexible systems. The(More)
OBJECTIVE Online health knowledge resources contain answers to most of the information needs raised by clinicians in the course of care. However, significant barriers limit the use of these resources for decision-making, especially clinicians' lack of time. In this study we assessed the feasibility of automatically generating knowledge summaries for a(More)
OBJECTIVES Left ventricular ejection fraction (EF) is a key component of heart failure quality measures used within the Department of Veteran Affairs (VA). Our goals were to build a natural language processing system to extract the EF from free-text echocardiogram reports to automate measurement reporting and to validate the accuracy of the system using a(More)
OBJECTIVE This paper presents the results of a systematic literature review and a formal analysis of the scientific quality of empirical research on computerized provider order-entry (CPOE) applications. DESIGN Formal, systematic review techniques were used to search the literature, determine study relevance, and evaluate study quality. MEASUREMENT A(More)
PURPOSE Computerized provider order entry (CPOE) is central to current efforts at improving clinical care. Understanding the quality of the evidence for CPOE is important to the practical decision of implementation, patient safety and future design efforts. This paper presents the results of a systematic analysis of the quality of systematic reviews of(More)
OBJECTIVE Fatal errors can occur in intensive care units (ICUs). Researchers claim that information integration at the bedside may improve nurses' situation awareness (SA) of patients and decrease errors. However, it is unclear which information should be integrated and in what form. Our research uses the theory of SA to analyze the type of tasks, and their(More)
PURPOSE This study explores multidisciplinary and cross-sector health professional experiences with the information needs for safe patient transfers across the care continuum using a Joint Cognitive Systems (JCS) model. Qualitative experiences of three JCS components and their attributes and are presented. METHODS A qualitative content analysis using(More)
Computerized decision support and order entry shows great promise for reducing adverse drug events (ADEs). The evaluation of these solutions depends on a framework of definitions and classifications that is clear and practical. Unfortunately the literature does not always provide a clear path to defining and classifying adverse drug events. While not a(More)
PURPOSE Implementation of evidence-based techniques, such as explicit computerized protocols, has achieved limited success among clinicians. In this study, we describe the development and validation of an instrument for assessing clinicians' perceptions about use of explicit computerized protocols. METHODS Qualitative assessment of semi-structured(More)
