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)
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)
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)
HealthInfoCDA denotes a health informatics educational intervention for learning about the clinical process through use of the Clinical Document Architecture (CDA). We hypothesize those common standards for an electronic health record can provide content for a case base for learning how to make decisions. The medical record provides a shared context to(More)
Clinical documents contain statements and facts about patients under treatment. They help to coordinate care and transmit knowledge among the clinicians contributing to patient care. However, studies show that documentation of important clinical information is generally poor and miscommunication is a leading cause of adverse events. The discharge summary is(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)
The advent of synoptic operative reports has revolutionized how clinical data are captured at the time of care. In this article, an electronic synoptic operative report for spinal cord injury was implemented using interoperable standards, HL7 and Systematized Nomenclature of Medicine-Clinical Terms. Subjects (N = 10) recruited for a pilot study completed(More)
The increasing use of synoptic operative reports in clinical settings represents a major milestone in the advancement of health information technology. Synoptic operative report templates enable clinicians to capture and display succinct clinical information in a standardized and logical manner. Synoptic operative report templates also provide the optimum(More)
A topic map is implemented for learning about clinical data associated with a hospital stay for patients diagnosed with chronic kidney disease, diabetes and hypertension. The question posed is: how might a topic map help bridge perspectival differences among communities of practice and help make commensurable the different classifications they use? The(More)
Background. With the help of teens in Nova Scotia, Dalhousie medical students have designed pages on the Internet to provide information on sexual and reproductive health issues that face young people today. was launched on the Chebucto Community Net, a non-profit organization which provides free Internet services in public locations and private homes.
