How can SCT be used within M? We are at the beginning of an implementation of M and are pretty lost when it comes to support for SCT in M. We get different answers depending on who we ask.
- is there a character limit for terms that will trunctate SCT terms?
- does M store the concept-ID and/or the descripition-ID or none of those? (the screenshots I have seen have displayed description-ID)
- Can M handle synonymity; ie different terms are displayed in different parts of the system and are still found to be the same concept?
- Can M use description logic to search past history of a patient, for example for anytging concerning the heart?
- Can M make intesional refsets 'on the fly' or only use extensional ones? How are they managed - externally or within Millennium?
very thankful for anyone who can shed some light on these topics

We are not using Cerner Millennium but know the Australia New South Wales state hospitals are using Cerner Millennium. They use SNOMED CT to replace ICD-10 code for clinical diagnosis and also use Australian Medication Terminology (a SNOMED CT local extension) in eMedication system. All of the discharge summaries have been coded in SNOMED CT and can be mapped to ICD-10 for generating DRGs. So far from I know:
1, no limitation for the SNOMED CT description which in theory should be less than 256 characters if I'm not wrong.
2, SNOMED CT concept ID will be saved as part of the discharge summary.
3, The diagnosis is from a reference set. So, all of the concepts and their descriptions have been defined. No synonymity should be used for that.
4, Haven't heart any eMR systems use description logic.
5, I believe there is a way to construct the reference set within Cerner or import from a file.
If you are interested in implementing SNOMED CT inside Cerner Millennium, eHealth NSW is one organisation to contact http://www.ehealth.nsw.gov.au/

I have some experience looking the Cerner Millenium implementation in Queensland, Australia. They have a standardised build implemented over a number of sites around the state.
SCT is being used in Millenium for Problems and Alerts, and Procedures
Hope that's helpful
