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.

Medical terminology is a specialization of the medical informatics discipline. It is rare that organizations have personnel familiar with application of specialized medical termionlogies. With this in mind, VTSL provides educational services and opportunities for veterinarians.

Online resources: VTSL maintains a repository of presentations given by laboratory personnel that relate to veterinary implementation of terminology standards, including but not limited to SNOMED-CT. VTSL also maintains a public browser that has been developed and maintained to allow exploration of SNOMED-CT by interested parties.

Post-DVM Education: VTSL is a division of the Veterinary Medical Informatics program at the Virginia-Maryland Regional College of Veterinary Medicine. We offer formal training leading to either a masters of science or PhD in Veterinary Medical Sciences with an emphasis in veterinary medical informatics. Interested parties should contact the Biomedical and Veterinary Sciences program at the VMRCVM or visit their webpage.
