Transcript Tooling for SNOMED-CT: Dion McMurtrie



Implementing terminology requires
supporting tools
Tools required are highly dependant on the
type of implementation
Covered in this presentation
◦ Types of implementation activities
◦ Types of tools required
◦ Description of some available tools

This presentation mentions tools and vendors
as examples
◦ but doesn’t imply how good, bad or
otherwise these tools are
◦ and can’t cover all known tools
Where to find more

Systems have existing
code sets
Native replacement can
be expensive and time
consuming
Mapping can be used for
interoperability
…however remember
that maintenance of
maps can also be costly
Tooling needed - Mapping

Not all possible tools are listed in this
presentation – there are others
Listing of tools in this presentation doesn’t
state how good, bad or otherwise the tools are
Tools are listed in no particular order
Tools won’t necessarily cover all features on
the slide on which they are listed, but will
have some relevant capabilities
You don’t need all of these tools – depends on
what you are doing
