Clinisys will provide you with the correct script. We deliberately release the test script through the LIMS providers to avoid confusion. We have released a second updated test script to Clinisys

Hello Alex,
Hope all well with you.
We have the same supplier clinisys and we use Masterlab ( Labcentre ) too. Clinicyc until this moment they could not give us a suitable algorithm to run NHSE proposed alert system.
Do you have the script? Our IT manager could not get hold of it. Or correctly Clinisys did not provide us with one.
Regards
Nudar

Subject: Persistent AKI flags
Hi all,
We recently went live on Clinysys Masterlab( labcentre ) system
The problem we are seeing is that although the initial AKI flag is correct, as the creatinine results improve the AKI flag is still present :
For example ( completely made up to illustrate a point)
The first flag may be due to a rise from a baseline creatinine in the past 7 day from 120(RV1) on day -6 to 187 (C1) on day 1 and the result flags as AKI 1
The next measurement on day 3 might show a decrease in creatinine to 140 ( new C1), however the algorithm is still flagging the result as AKI.
I believe it may be looking back between 7 and 365 days and finding a very low mean (RV2) or just a very low result, and hence the AKI flag is always being added to the improving Creatinine.
Although flagging the result as AKI isn’t necessarily incorrect it isn’t how I believed (perhaps wrongly)the algorithm would work, as I thought it would only use the mean of 7-365 day (RV2) if NO creatinine result (RV1)was available in days 1-7 as it is it seems to look at both RV2 and RV1 and choose the lowest.
Does anyone have any clarification of this of have they seen anything similar.
I don’t know if our algorithm has a bug or this is how it was designed to work- any feedback very welcome
Thanks
Alex
