Dear All, I created now a new topic for this as I have several questions related to DqD I’ll copy here also my original posting and Clair’s answer to it :
Dear All, referring to Don Torok’s posting, I suspect that we have a similar issue with the following tests:
combination of CONCEPT_ID 3015377 (CALCIUM [MOLES/VOLUME] IN SERUM OR PLASMA) and UNIT_CONCEPT_ID 8753 (MILLIMOLE PER LITER), the number and percent of records that have a value less than 7.000 – our normal ranges with the unit 8753 (MILLIMOLE PER LITER) are 2.15 -2.7 and all our records have values under 7.000 ! I wonder if these plausible low and high values might actually be referring to the unit 8840 (mg/dl) ?
Further to this subject, are we allowed to modify the plausible values in the Control files? Or we should just modify the threshold and add a note explaining why we have so many records failing the check? Would be great if someone would comment, Thanks so much!
Thanks so much @tajanenp! I agree it seems like the units are off and it makes sense to update the plausible values in the control files. Would you be willing to send us a pull request to fix the issue?
Dear Clair, thank you for your prompt reply! I will get back to the pull request a bit later as i suspect we have at lest one more case like that but may I ask you , or anyone , another more general question about the plausible values/thresholds; We seem to have quite some cases where we go slightly or significantly over the thresholds (% records 5.5 up to 50%) and at least at first glance I don’t see anything wrong with the data. So my question is that, how these plausible values are set? And as we are a University hospital, our patient population consist of lots of seriously ill patients, might that explain why we do not seem to fit in the default values/thresholds? Many thanks again, I appreciate all the advice we can get, as I am still at the beginning of the learning curve with this great project!
