SOURCE – electronic health record (EHR) data enters our system with terms and codes for conditions, drugs, and procedures using “source vocabularies”. Source vocabularies are the original methods of classifying conditions, diagnoses and procedures (e.g. ICD9 and ICD10CM codes) and will be “mapped” to the new standard vocabularies. However, the source vocabularies are retained after the mapping and data can still be searched using the original terminology or codes.
STANDARD – Translation of clinical findings, symptoms, diagnoses, procedures, etc. from traditional methods of coding and classification into what is referred to as a “standard vocabulary” allow EHRs to be more readily categorized and searchable. Examples of standard vocabularies include SNOMED, LOINC, and RxNorm.
