OBJECTIVE To evaluate the ability of systematized nomenclature of medicine clinical terms (SNOMED CT) to represent computed tomography procedures in computed tomography dictionaries used in the Canadian province of Newfoundland and Labrador. METHODS This study was conducted in two stages. In the first stage computed tomography dictionaries were collected(More)
PURPOSE Poor documentation in medical records might reduce the quality of care and undermine analyses based on retrospective chart reviews. We assessed the documentation of cardiac risk factors and cardiac history in the records of patients hospitalized with myocardial infarction or heart failure. METHODS We performed a retrospective cohort study(More)
The XML-based Clinical Document Architecture (CDA) for document exchange defines a three-level document architecture with each higher level adding more specificity to the markup of the document. Such a layered architecture also meets the requirement for semantic processing of hierarchically structured clinical documents. The CDA supports shared care between(More)
At Dalhousie, we integrated medical informatics as a horizontal theme in the problem-based learning undergraduate medical education curriculum. The rationales for these initiatives can be addressed along the following dimensions: political, philosophical, psychological, educational, and professional practice. Student attitudes towards computers are(More)
BACKGROUND The need for physicians to be proficient in the use of computers is undeniable. As computers have become easier to use and more widespread, their use in medicine is expanding. Several organizations have produced continuing medical education programs to teach physicians about the use of computers in medicine but little has been reported on the(More)
This study used the original model of rough sets for data analysis of objective clinical findings from pneumonia patients. Rough sets data analysis was used to draw data dependencies, data reductions, approximate set classifications, and rule inductions from records in a clinical database. This study utilized Pawlak's rough classification algorithm [1] to(More)
Our electronic medical record (EMR) case study research pursued a set of questions to provide Canadian physicians with practical information on best practices and lessons learned regarding implementation and use of EMRs in ambulatory clinical care. The study's conceptual framework included an EMR System and Use Assessment Survey, interview guide,(More)
This study transforms clinical narrative in three knowledge-rich modalities: case writeup, patient record and online desk reference to develop a casebase of clinical knowledge useful for medical and health education. We process a medical text corpus through MetaMap Transfer, which discovers UMLS Metathesaurus concepts in text. Our ultimate purpose is to(More)
A case-based reasoning (CBR) decision support system (DSS) is well-suited to a clinical environment where there are novel problems and a low volume of cases, such as the Bone Marrow Transplant (BMT) Clinic in Halifax. The focus is experience management of the BMT patient to avoid post-transplant complications. We leverage Health Level Seven (HL7) Clinical(More)
