Some of Our Success Stories


National Health Service Digital

NHS Digital has migrated their entire terminology authoring platform to Snow Owl to manage and publish the SNOMED CT UK Edition, including a clinical and a drug extension, both significant in size.

The creation of intensional and extensional subsets, maps to additional terminologies and the maintenance of separate interdependent modules are fully managed by Snow Owl. A team of authors are working together in a collaborative authoring environment, utilizing the workflow capabilities of Snow Owl to share and distribute authoring tasks among each other.

Besides the authoring environment, NHS Digital is using our online browser and refset builder tool, Snowray.

Alberta Health Services

AHS, Canada uses Snow Owl to maintain their provincial extension of SNOMED CT. Besides SNOMED CT, a variety of Local Code Systems are maintained and published for downstream systems (Epic, IMO). Snow Owl is used for the creation of mappings between these code systems and also for curating localized versions of ICD-10 and CCI.

American Dental Association

The ADA manages their SNODENT Extension mappings using Snow Owl. Besides the maintenance of terminology maps between SNOMED CT and their local codes, they are exposing their extension to downstream customers using a custom-built web browser.

University of Nebraska Medical Centre

The UNMC builds extensions in the domain of Pathology, Laboratory Observables and Clinical Observables extending the international SNOMED CT concept model with additional attribute and concrete domain types.
