Feedback QA Panel has had from EQA providers is that all UK labs are reporting to them in mass units, so unless someone is not treat8ing EQA samples as if they are patient samples…………….

All UK labs have been directed to use mass units to the base the litre. Not to do so I would say is negligent!

As far as I know all labs are compliant.

Note which way around the scale of units is on paracetamol “overdose” chart

 

Tendency is to read left hand axis. If using SI units, error likely to occur

 

I know, have seen a case

 

Question is, why does even the BNF persist in printing charts with both units – which would allow confusion to potentially arise. UK only uses 1 unit …….maybe junior doc who makes an error would have a defence and could sue BNF for perpetuating risk J

well, only time will tell.

 

mg/dl: Yes in the USA and the rest of Europe!

 

Have you heard there are still places where units of reporting for paracemaol overdose are confused, esp.. as 'GP' out of hours are increasingly manned by non-UK grads/ trained? So there is still a risk even though all the lab in UK adhere to the 2006 consensus.

 

Have you ever seen a doc in a clinical meeting mentions  unit of reporting during case discussions?!

 

May be labs should dual report everything!

 

 

 

 

"Why do patients still die from paracetamol poisoning? (BMJ 2011; 342 doi: http://dx.doi.org/10.1136/bmj.d2218 (Published 20 April 2011) Cite this as: BMJ 2011;342:d2218

Treatment errors can occur when paracetamol concentrations are misunderstood. The cardinal measurement in ascertaining risk is the timed plasma paracetamol concentration. Patients have died when doctors have thought that results quoted in mmol/L are actually in mg/L (151 mg=1 mmol) and have therefore withheld acetylcysteine.32 "

Surely, that’s acceptable.

 

We’re giving an analytically correct value : they are translating into what they understand.

 

But over time they’ll get used to the “new numbers” and won’t need the tables.

 

Who else is old enough to remember the change from mg/dL ?

 

Michael

 

 

We stopped dual reporting but it transpired that users, or at least unknown number of them,  have printed conversion tables to convert back to old monies. May be  that is why ' we have had no problems or complaints'!

Dear All

Quick show of hands - how many labs are still reporting HbA1c in both DCCT & IFCC numbers?

My hand is up! It will be interesting to see if our lab is out on a limb.............

Shirley
