OBJECTIVES The goal of this study was to evaluate the utility of a rapid "bedside" technique for measurement of B-type natriuretic peptide (BNP) in the diagnosis of congestive heart failure (CHF) in an urgent-care setting. BACKGROUND B-type natriuretic peptide is a protein secreted from the cardiac ventricles in response to pressure overload. One(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)
BACKGROUND Schizophrenia is a common severe syndrome with a highly variable pattern of symptoms. The medications used to treat this disorder are expensive and may cause severe adverse effects. Little is known about how the public perceives health outcomes in schizophrenia or the potential adverse effects of antipsychotic medication. This complicates the use(More)
Mobile information technology can help first responders assist patients more quickly, reliably, and safely, while focusing resources on those most in need. Yet the disaster setting complicates reliable networked computing. The WIISARD client-server architecture provides mobile IT support for medical response in disasters. Cached remote objects (CROs) are(More)
Utilities are numeric measurements that reflect an individual's beliefs about the desirableness of a health condition, willingness to take risks to gain health benefits, and preferences for time. This report discusses the approaches to assess and compare the validity of methods used to assign utilities for cost-utility analysis. Threats to validity include(More)
OBJECTIVE To define objectively and describe a set of clinically relevant health states that encompass the typical effects of depression on quality of life in an actual patient population. Our model was designed to facilitate the elicitation of patients' and the public's values (utilities) for outcomes of depression. DATA SOURCES From the depression panel(More)
802.11 (WiFi) is a well established network communications protocol that has wide applicability in civil infrastructure. This paper describes research that explores the design of 802.11 networks enhanced to support data communications in disaster environments. The focus of these efforts is to create network infrastructure to support operations by(More)
BACKGROUND Utilities for health conditions, including major depressive disorder, have a theoretical relationship to health-related quality of life (HRQOL). Because of the complexity of utility measurement and the existence of large numbers of completed studies with HRQOL data but not utility data, it would be desirable to be able to estimate utilities from(More)
OBJECTIVES The goal of this study was to determine if B-type natriuretic peptide (BNP) levels predict outcomes of patients admitted with decompensated heart failure. BACKGROUND Treatment of decompensated congestive heart failure (CHF) has often been based on titration of drugs to relieve patient's symptoms, a case that could be made for attempting to also(More)
