The computerized medications order entry system currently used in the public hospitals of Hong Kong does not have decision support features. Plans are underway to add decision support to this system to alert physicians on drug-allergy conflicts, drug-lab ...
to evaluate the feasibility, potential and risks of an internet-based telemedicine network in developing countries of Western Africa.a project for the development of a national telemedicine network in Mali was initiated in 2001, using internet-based technologies ...
The aim of this work was to determine whether the GEM-encoding step could improve the representation of clinical practice guidelines as formalized knowledge bases. We used the 1999 Canadian recommendations for the management of hypertension, chosen as ...
We previously developed a deterministic record linkage algorithm demonstrating sensitivities approaching 90% while maintaining 100% specificity. Substantially better performance has been reported using probabilistic linkage techniques; ...
Imaging modalities are widely used to explore and diagnose diseases. Feature extraction methods are used to quantitatively describe and identify objects of interest in acquired images, typically involving data compression. The extracted features are subject ...
As routine use of on-line progress notes in US Department of Veterans Affairs facilities grew rapidly in the past decade, health information managers and clinicians began to notice that authors sometimes copied text from old notes into new notes. Other ...
The purpose of this study was to explore whether the ISO reference terminology model for nursing diagnoses could be generalized to the MDS data set that, like nursing terminologies standardizes expressions of the concepts within and relevant to the domain ...
The NCI Thesaurus™ is a public domain description logic-based terminology produced by the National Cancer Institute. The NCI Thesaurus™ is used to support storage and retrieval of scientific, clinical and research administration data. ...
In this paper, we use the theory of distributed cognition to understand work practices in terms of the behavior of an activity system. We do so by detailing the roles that local representations of information play in the social, cognitive, organizational, ...
Data mining in time-series medical databases has been receiving considerable attention since it provides a way of revealing useful information hidden in the database; for example relationships between the temporal course of examination results and onset ...
Computer-based provider order entry (POE) can reduce the frequency of preventable medical errors. However, overly complex interfaces frequently pose a challenge to users and impede clinical efficacy. We present a cognitive analysis of clinician interaction ...
Handheld computers have advantages for physicians, including portability and integration into office workflow. However, negative patient perceptions of physician use of handheld computers in the examining room might limit integration.To survey patients’ ...
This paper results from the research efforts of the Clinical Informatics Research Group in building a generalized system for online survey implementation. Key to the success of any generalized survey system is a standard ontology for the differing components ...
The Veterans Health Administration (VHA), of the U.S. Department of Veteran Affairs, operates one of the largest healthcare networks in the world. Its electronic medical record (EMR) is fully integrated into clinical practice, having evolved over several ...
In intensive care, physiological variables of the critically ill are measured and recorded in short time intervals. The proper extraction and interpretation of the essential information contained in this flood of data can hardly be done by experience ...
We conducted a retrospective study to ascertain the potential of free-text chief complaints collected in pediatric emergency departments to serve as surveillance data for early detection of outbreaks.We determined that automatically coded chief complaint ...
Arden Syntax is a Health Level Seven (HL7) standard that can be used to encode computable knowledge. However, dissemination of knowledge is hampered by lack of standard database linkages in Arden knowledge bases (KB). Moreover, the HL7 Reference Information ...
Hypertutorials optimize five features – presentation, learner control, practice, feedback, and elaborative learning resources. Previous research showed graduate students significantly and overwhelmingly preferred Web-based hypertutorials to conventional ...
The problem of developing a curriculum for biomedical informatics is highly dependent on how we choose to define and practice the field. Numerous authors have questioned how to position biomedical informatics along the continuum of formal, empirical and ...
A Computerized Physician order entry (CPOE) system was successfully implemented at the Ohio State University Medical Center (OSUMC) in February 2000. The electronic entry and use of order sets is designed to standardize patient care and improve efficiency ...
Medical problems left unresolved during hospitalizations (along with recommended outpatient evaluations, test results pending at discharge, and discharge medication regimens) are often documented in patients’ discharge summaries. However, studies ...
Usability engineering often involves experimental evaluation designs carried out in special usability laboratories. Though becoming more popular in medical informatics, the approach is little used. Possibly this is because of the expense involved in set-up, ...
The Unified Medical Language System® (UMLS®) , an extensive source of biomedical knowledge developed and maintained by the US National Library of Medicine (NLM) is being currently used in a wide variety of biomedical applications. The ...
Telemedicine has the potential to transcend geographic and socio-cultural barriers to the delivery of high quality health care to the medically underserved populations. However, there are significant cognitive and usability barriers. This paper presents ...
Computerized physician order entry (CPOE) systems represent an important tool for providing clinical decision support. In undertaking this systematic review, our objective was to identify the features of CPOE-based clinical decision support systems (CDSSs) ...
