Small Animal Problem and Diagnosis Terms Consolidated

April 1, 2023
VTSL would like to announce the consolidation of the AAHA Problem and Diagnosis Terms (AAHA PDT) and the Small Animal Specialty Problem and Diagnosis Term (SAS PDT). The AAHA PDT were initially created and supported by the American Animal Hospital Association to provide standardized terms for use in general small animal practice in order to support better data collection in private practice. The success of the AAHA PDT led Blue Pearl Veterinary Partners to collaborate with VTSL in the creation of the SAS PDT to be used in conjunction with the AAHA PDT in specialty practice. As more and more veterinarians seek advanced training to expand their practices abilities to diagnose and treat their patients, it has become increasingly difficult to determine what content is needed for general practice and what is only of interest to a specialist. Therefore, VTSL has determined that the veterinary community will be best served by consolidation of these two subsets. The Small Animal Problem and Diagnosis Terms (SA-PDT) will replace both the AAHA PDT and the SAS PDT, and will contain all content relevant to small animal practice, inclusive of general, specialty and emergency practice. One last release of the SAS PDT is available which shows all content retired for completeness. The final SAS PDT release is available in the SAS project. The new consolidated SA-PDT is available in the SA PDT project. VTSL also continues to maintain the AAEP Problem and Diagnosis Terms for equine practice. It is available in the AAEP Project.

Terminology Development

SNOMED-CT®: VTSL provides expertise to the International Health Terminology Standards Development Organization (IHTSDO) for evaluation of the Systematized Nomenclature of Medicine - Clinical Terms (SNOMED-CT®) relative to its coverage of veterinary nomenclature and for the addition of new concepts that relate specifically to veterinary medicine.

Veterinary Adaptation of SNOMED-CT®: VTSL is developing a veterinary-specific adaptation of SNOMED-CT®. The long-term goal of this project is to create a terminology product that includes medical concepts of interest to our veterinary clients and excludes concepts that are not of veterinary interest. As part of this project we create and maintain a legal extension of the SNOMED-CT® core. This extension holds concepts that are of veterinary import as well as additional terms (synonyms) used by veterinarians that are not in common use in human medicine.
