Units of Measure in PCLOCD

In SK we receive and distribute all results with the date format yyyy/mm/dd and time in 24hr format

However when they are displayed within the downstream systems they are dd/mmm/yyyy and the time is 12 hr clock with the AM/PM distinction. We also have one system that displays yyyy/mmm/dd with the 24hr format and one with the 12hr format with the AM/PM distinction. Just something to consider

Hi Alison,

In Ontario we also use YYYYMMDD.

Hi Allison, in New Brunswick we use yyyy/mm/dd. Marion

Thanks Alison for the question.

Just to set some background and context for others on this thread, Alison did reach out to us with this question. After relaying some of the background of the pCLOCD, UCUM and the ISO date format, I recommended that Alison post to the forum to see what date format implementers were actually using.

Over the years, the Canadian Association of Clinical Chemists has been kind enough to provide recommended units of measure for use in Canada. It would appear that recommended units of measure for dates in the pCLOCD were never provided which is why they are not in the pCLOCD.

When we looked at the LOINC database, we did notice examples date formats using UCUM to properly create this unit of measure, but noticed that the example units did not follow the ISO date format.

For those that have implemented and are using the pCLOCD, are you using the ISO date format to represent dates?

Real world implementation guidance is appreciated.

Thank you.

Regards,

Andrea

Hi Alison,
Thank you for your question!

Our Toronto office is closed today.
The LOINC/pCLOCD expert will be pleased to answer your question tomorrow... unless someone from the community can provide an answer in the meantime!

Hello.

I am wondering if anyone can help clarify how dates are captured in LABs.
Canada's preferred format for capturing "date" on official documents is, iso yyyy/mm/dd
LOINC uses examples of UCUM and such as "date of death" mm/dd/yyyy.
How does PCLOCD capture dates?

Thanks
Alison Morra
