One of the more difficult tasks of informatics is allowing for the navigation of complex databases. At Partners Healthcare Inc. we have developed an analytical database to allow for searching clinical data to obtain cohorts of patients for research studies. ...
The paper focuses on the neuro-fuzzy classifier called Fuzzy-Gaussian Neural Network (FGNN) to recognize the ECG signals for Ischemic Heart Disease (IHD) diagnosis. The proposed ECG processing cascade has two main stages: (a) Feature extraction from the ...
We have previously developed a fuzzy logic controller for weaning adults with chronic obstructive pulmonary disease using pressure support ventilation (PSV). We used the core of our fuzzy logic-based weaning platform and further developed parametrizable ...
Participants at the Nursing Terminology Summit Conference 2002 developed proposed terminology models and information models for findings, goals, and outcomes and described the relationships among these concepts. At Vanderbilt University the author has ...
Computer-interpretable clinical guidelines (CIGs) aim to eliminate clinician errors, reduce practice variation, and promote best medical practices by delivering patient-specific advice during patient encounters. Clinical guidelines are being regularly ...
Systems that attempt to integrate and analyze data from multiple data sources are greatly aided by the addition of specific semantic and metadata “context” that explicitly describes what a data value means.In this paper, we describe a ...
In home care, workers from different disciplines treat patients in their homes. However, workers who treat a shared patient are mobile and rarely see each other face-to-face, so it is difficult for them to maintain awareness of others’ activities. ...
Dynamic settings possess complex information needs all requiring attention in order to be managed effectively. The following study describes the multi-faceted information exchanges essential for an operating room suite to be managed within the context ...
Although huge amounts of unstructured text are available as a rich source of biomedical knowledge, to process this unstructured knowledge requires tools that identify concepts from free-form text. MetaMap is one tool that system developers in biomedicine ...
We describe a telemedicine application for emergency management in Stroke Units, where prompt decisions must be taken, often knowing neither the clinical history nor the stroke symptoms onset modality. We have designed and implemented an Information and ...
The use of information technology to provide health information to the public has grown at a rapid pace. Numerous sources of health care information within both the print and Internet media are now available. Yet, their availability raises concerns about ...
Pagers, personal data assistants (PDAs) and other devices that have wireless connectivity are becoming a popular method for delivering patient related information to medical decision makers. Although medical informatics research has emphasized the design, ...
Syndromic surveillance systems are being deployed widely to monitor for signals of covert bioterrorist attacks. Regional systems are being established through the integration of local surveillance data across multiple facilities. We studied how different ...
Considerable research is being directed at extracting molecular biology information from text. Particularly challenging in this regard is to identify relations between entities, such as protein-protein interactions or molecular pathways. In this paper ...
In this study we use the principles of distributed cognition and the methodology of human-centered distributed information design to analyze a complex distributed human-computer system, identify its problems, and generate design requirements and implementation ...
The U.S. National Institutes of Health, through its National Library of Medicine, developed ClinicalTrials.gov to provide the public with easy access to information on clinical trials on a wide range of conditions or diseases. Only English language information ...
The National Drug File Reference Terminology contains a novel reference hierarchy to describe physiologic effects (PE) of drugs. The PE reference hierarchy contains 1697 concepts arranged into two broad categories; organ specific and generalized systemic ...
We describe a cognitive approach to evaluating the factors that motivate clinicians to use computerized protocols. Using Value-Expectancy theories we developed an open-ended interview with providers experienced with using computerized protocols to assess ...
We present a data-driven approach to extract the “most specific” terms relevant to an ontology of functioning, disability and health. The algorithm is a combination of statistical and linguistic approaches. The statistical filter is based ...
We have developed a method that extracts structured information about specimens and their related findings in free-text surgical pathology reports. Our method uses regular expressions that drive a state-automaton on top of XSLT and Java. Text fragments ...
The Digital Electronic Guideline Library (DeGeL) is a Web-based framework and a set of distributed tools that facilitate gradual conversion of clinical guidelines from free text, through semi-structured text, to a fully structured, executable representation. ...
As the healthcare industry transitions from paper to electronic medical records (EMRs), medical informatics researchers face the task of ensuring that the electronic presentation of the information remains usable and effective while capitalizing on the ...
Computer-based clinical decision support systems (CDSSs) vary greatly in design and function. A taxonomy for classifying CDSS structure and function would help efforts to describe and understand the variety of CDSSs in the literature, and to explore predictors ...
We present a MR brain atlas for structure and function (diffusion weighted images). The atlas is customizable for contrast and orientation to match the current patient images. In addition, the atlas also provides normative values of MR parameters. The ...
The rapidly increasing wealth of genomic data has driven the development of tools to assist in the task of representing and processing information about genes, their products and their functions. One of the most important of these tools is the Gene Ontology ...
