Evaluating a Hierarchical Clinical Event Linkage Model for Clinic-Specific Databases.

Studies in health technology and informatics
A relational database model is presented that stores the hierarchical linkages between clinical events with qualifier codes, such that the explicit contextual meaning of an event's attributes is preserved upon retrieval. A retrospective analysis of 3...

Developing a Standards-Based Information Model for Representing Computable Diagnostic Criteria: A Feasibility Study of the NQF Quality Data Model.

Studies in health technology and informatics
The lack of a standards-based information model has been recognized as a major barrier for representing computable diagnostic criteria. In this paper we describe our efforts in examining the feasibility of the Quality Data Model (QDM)-developed by th...

A Novel Approach to Create a Machine Readable Concept Model for Validating SNOMED CT Concept Post-coordination.

Studies in health technology and informatics
Post-coordination provides the means to achieve an appropriate content coverage, which is critical in successfully adopting clinical reference terminologies, and thus represent clinical information consistently. However, one of the major problems of ...

Cohort Discovery Query Optimization via Computable Controlled Vocabulary Versioning.

Studies in health technology and informatics
Self-service cohort discovery tools strive to provide intuitive interfaces to large Clinical Data Warehouses that contain extensive historic information. In those tools, controlled vocabulary (e.g., ICD-9-CM, CPT) coded clinical information is often ...

A new approach for cleansing geographical dataset using Levenshtein distance, prior knowledge and contextual information.

Studies in health technology and informatics
Epidemiological studies are necessary to take public health decisions. Their relevance depends on the quality of data. Doctors in continuous care collect a big amount of data that can be used for epidemiological purpose, but spatial data may be dirty...

Identifying redundant and missing relations in the gene ontology.

Studies in health technology and informatics
Significant efforts have been undertaken for providing the Gene Ontology (GO) in a computable format as well as for enriching it with logical definitions. Automated approaches can thus be applied to GO for assisting its maintenance and for checking i...

Toward a patient safety upper level ontology.

Studies in health technology and informatics
Patient Safety (PS) standardization is the key to improve interoperability and expand international share of incident reporting system knowledge. By aligning the Patient Safety Categorial Structure (PS-CAST) to the Basic Formal Ontology version 2 (BF...
