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)
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)
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)
PURPOSE Effective interdisciplinary exchange of patient information is an essential component of safe, efficient, and patient-centered care in the intensive care unit (ICU). Frequent handoffs of patient care, high acuity of patient illness, and the increasing amount of available data complicate information exchange. Verbal communication can be affected by(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)
Falls and related injuries are increasingly being recognized as a nursing-sensitive quality indicator, and they continue to be an unsolved patient safety problem in inpatient and outpatient care areas as well as in the community at large. The purpose of this review is to summarize the current research related to fall and injury prevention. The chapter is(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)
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)
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)
