The purpose of this paper is to describe a framework for evaluating image segmentation algorithms. Image segmentation consists of object recognition and delineation. For evaluating segmentation methods, three factors-precision (reliability), accuracy (validity), and efficiency (viability)-need to be considered for both recognition and delineation. To assess(More)
Interest in studying distractions and interruptions in the context of clinician workflow has increased in light of evidence that these events may negatively impact patient safety. Additionally, many recent informatics-based studies analyze computer provider order entry (CPOE) and clinical information system (CIS) implementation and its effects on clinician(More)
Patient safety efforts advocate for transforming healthcare from a culture of blame to a non-punitive "culture of safety." One of the most challenging hurdles is to encourage healthcare practitioners to be mindful about their activities. To promote mindfulness during clinical education for entry-level nurses, we developed a web-based dangerous situation and(More)
INTRODUCTION The development of tools to meet the information needs of clinicians requires an understanding of the clinician and the context in which clinical decisions are being made. METHODS We conducted an observational study of clinicians' information needs via think-aloud protocols during which we observed physicians and nurses as they used the(More)
BACKGROUND Clinical information system (CIS) use is likely to evoke information needs, yet information resources use during CIS use has not been studied. METHODS We used CIS log files and a survey to characterize clinicians' use of resources and infobuttons (context-sensitive links from a CIS to specific resources) while using a CIS. RESULTS We examined(More)
Online medical information, when presented to clinicians, must be well-organized and intuitive to use, so that the clinicians can conduct their daily work efficiently and without error. It is essential to actively seek to produce good user interfaces that are acceptable to the user. This paper describes the methodology used to develop a simplified heuristic(More)
INTRODUCTION Information needs are prevalent in clinical practice. They represent a potential source of medical errors. This study seeks to empirically determine the information needs of clinicians while using a clinical information system (CIS), and characterize those needs. In addition this paper will provide the framework necessary for the development of(More)
The AMIA biomedical informatics (BMI) core competencies have been designed to support and guide graduate education in BMI, the core scientific discipline underlying the breadth of the field's research, practice, and education. The core definition of BMI adopted by AMIA specifies that BMI is 'the interdisciplinary field that studies and pursues the effective(More)
PURPOSE Clinical practice guidelines (CPGs) are common tools for clinicians in daily practice. In order to use CPGs effectively at the point of care, representing CPGs into computer-interpretable format is essential. Since computer-interpretable guidelines (CIGs) have been reported to increase clinicians' usage of guidelines and improve patient's outcomes,(More)
