The SNOMED CT Route of Administration subset data file is a tab-delimited file with the following fields:
- SNOMED_CID – conceptId of the SNOMED CT concept
- SNOMED_PT – The SNOMED CT preferred term
The file identifies what we hope is a useful subset of SNOMED CT, but does not include all of the information likely to be required to make effective use of SNOMED CT in an application, such as synonyms that may include more clinician-friendly terms than the SNOMED CT fully-specified name. In addition, the file is not intended to be an exhaustive list of routes of administration. For instance, the term “intravenous” (referring to administration through a vein) is included because it is widely used, but the term “intracephalic” (referring to administration through the cephalic vein of the arm) is not included because it is typically not used. The identifiers in the file can be used to extract more complete information for these concepts from the SNOMED CT native format files.
