The Case for a Pediatric Terminology
Terminologies are structured collections of designations (“terms”) that describe entities and relationships that represent the knowledge within a given domain.1,2 Terms may consist of words, phrases, or other notations (such as numbers or symbols), and are designed to support communication, storage, retrieval, and use of knowledge and information by humans and machines. An example is the clinical entity of “blood pressure measured during the diastolic phase of the cardiac cycle,” which is designated (in the terminology SNOMED CT) by the preferred term “Diastolic blood pressure” and the concept identifier “271650006.” Terminologies can formally define and specify representation of information content, and when used with messaging standards, can support structured information exchange among different electronic patient care systems. Terminologies have been developed with differing levels of rigor, and best practices have been described.2,8
