VMDB has collected data on animal diseases since 1964 through member hospitals at North American Veterinary Colleges. Our servers are located at the University of Missouri, College of Veterinary Medicine. This endeavor has been generously sponsored by The Orthopedic Foundation for Animals (OFA). VMDB has over 6 million archived records stored using SNVDO from 1968 to the early 2004. SNVDO is no longer used as it has not been maintained and updated. SNOMED CT has been used to record clinical data since 1996. The database with SNOMED CT records includes approximately 580,000 patients, 1.4 million visits and over 14 million concepts records. Currently contributing member institutions have unlimited access for searching. Non-member searches are available for a fee upon written request for specific topics.
