Online laboratory manuals have developed into an important gateway to the laboratory. Clinicians increasingly expect up-to-date laboratory test information to be readily available online. During the past decade, sophisticated Internet search technology has developed, permitting rapid and accurate retrieval of a wide variety of content. We studied the role(More)
This paper presents a new method for detecting Ventricular Fibrillation (VF) based on a two step processing. The first one, based on the published VF Filter Leakage Method, consists in sampling data from the ECG and filtering it so that the more the signal resembles a sinusoidal wave, the lower the filter's output value will be. This idea comes from the VF(More)
ion to represent associations among different concepts (e.g., actors, use case, class, etc.). Underlying these diagrams and modeling concepts is the UML metamodel which is built on top of MOF as given in Figure 2a: M3 is a meta-meta library for defining new metamodels; M2 is at the metamodel layer where models such as UML, ODM, and NeOn (Haase, Rudolph,(More)
We report on the use of Contextual Design (CD) to develop models of the information management, resource integration, and collaborative processes of medical students in problem-based learning groups. CD is a modified ethnographic technique designed to provide a detailed understanding of the user's needs. Although the technique has been used in(More)
Today’s systems use a myriad of data formats (e.g., XML, RDF, JSON, SOAP, etc.) for data exchange and sharing. This is particularly true for health care, where patient information is stored in different locations via electronic media and/or hard-copy formats. Such information is of interest to: providers (MDs, RNs, therapists, etc.) to support patient care;(More)
Study Objectives Infants, children, and adolescents are increasingly being prescribed continuous positive airway pressure (CPAP) for treatment of obstructive sleep apnea syndrome (OSAS), yet adherence is often poor. The purpose of this study was to examine the relationship between caregiver and patient-reported health cognitions about CPAP prior to starting(More)
Laboratory medicine is not adequately addressed in most medical school curricula. A review of the literature was performed to evaluate the feasibility of an intelligent tutoring system to enhance laboratory medicine training. This appraisal suggests that such a system must integrate basic science and clinical training. A system equipped with a clinical(More)
Ontologies have gained increasing usage to augment an application with domain knowledge, particularly in healthcare, where they represent knowledge ranging from: bioinformatics data such as protein, gene, etc. to biomedical informatics such as diseases, diagnosis, symptoms, etc. However, the current ontology development efforts and process are data(More)
