Domain for "Polysomnography (PSG)" and "Evoked Potentials"

Hi All,

I would like to know which domain would be suitable for "Polysomnography (PSG)" and "Evoked Potentials" forms. I can see in SDTM IG Page 281 that "SL" domain is reserved for Sleep (Polysomnography) Data however it is still under discussion.

So, in this case, which domain would be suitable for this data?

Should I map it to FA domain?

Hi Dhanajay, Please check

Hi Dhanajay,

Please check CDISC Control Terminology. It includes "Domain Abbreviation" codelist which 90 terms in version 2013-06-28. See if it can be helpfull for you.

E.g., SL - Sleep Polysomnography Data.

Hi Sergiy, Thank you so

Hi Sergiy,

Thank you so much for the response. I have checked the SDTM Terminology and I was able to find SL domain, however SDTM 3.1.2 says that this domain is still under discussion and our study uses SDTM 3.1.2 Version. So in this case would it be fine to use SL domain?

Actual text from SDTM IG page 278.

Sleep Data (SL) is not under development, but under discussion.

Included as a value in the list of controlled terms, codelist Domain Abbreviation (C66734) at

Hi!

Coming back to the SL domain, it does not exist anymore. Can we still use it? Or is it better to use another domain...I suppose in this case it would be the Findings domain?

Hi Manolya, Yes, you can…

Hi Manolya,

Yes, you can still use SL domain name for your custom domain.

CDISC team removed it from SDTM CT codelist in 2018 with explanation that "Domain will not be incorporated in SDTMIG 3.3. This term will be added back if or when the domain is incorporated into a future version of SDTMIG."

I do not see any major differences in either utilization of SL or other name for your custom domain until this type of data will be promoted by CDISC to standard domain. Therefore, I choice would be to not make any changes in your existing process and keep "SL" name.

Kind Regards,
Sergiy
