Standardized Terminologies (ST) in
... [Show More] Practice
Standardized terminologies (STs) contribute to the development of knowledge because they ensure that all professionals share the same understanding or meaning of a given concept, to clarify communication, facilitate research, and provide structure for decision support tools and EHRs. As you look at the Foundation of Knowledge model, STs support knowledge acquisition, dissemination, generation, and processing.
STs are structured, controlled languages developed to represent concepts in a given domain in a clear, unambiguous fashion that conveys the exact same meaning for data, information, and knowledge across settings, regions, and even different countries. This consistency affords access to information and knowledge when it is needed without regard to the current model or period of care. STs are key to the development of an EHR in order to represent, communicate, exchange, reuse, and report data, information, and knowledge, including Meaningful Use criteria (Matney & Lundberg, 2013). In addition to vocabularies, terminology standards also include nomenclatures, classification systems, data sets, and code sets. Each will be discussed briefly.
Defining Characteristics
Guidelines for the development of standard terminologies were established during the late 1990s and remain in use today (Cimino as cited in Matney & Lundberg, 2013). Cimino's guidelines included 12 items. Guidelines addressed aspects that include content, concepts, and identification of concepts, hierarchy, relationships, and formal definitions. Terminologies are based upon concepts rather than terms and allow for growth over time. Also, once concepts enter a terminology, they should not be deleted or reused. While a concept has a single unambiguous meaning, it can have one or more representations or synonyms. Each concept has a unique identifier known as a code, which is made of alphanumeric characters. The code supports tracking data for various purposes, including evidence-based practice, decision support, and reports.
Current Terminologies and Language
Despite the intent of STs to represent concepts in a clear, unambiguous fashion, the numbers and different types of terms used to discuss STs can be confusing initially. Some of these terms include the following. [Show Less]
