Urine output and serum creatinine measurements

[FrancescaAlf]

Hi, I have questions about urine output and serum creatinine measurements in the DB.

I found several itemid related to urine output: UrineCAD, UrineSupraPubic, UrineUP, UrineSpontaan, UrineIncontinence should I consider all of them or just a few as valid measurements extracted from the patient’s catheter? Also, some acronyms used are unclear to me (ex: UrineUP, UrineCAD), could you provide me with more details?

About serum creatinine: could you explain the difference between Kreatinine (bloed), A_Serum_Kreatinine, MCA_Serum_Kreatinine and RA_Serum_Kreatinine? They are all expressed in umol/l, but are all of them extracted from blood (except from the first one where is specified)?

Thanks

All of them are urine output measurements: UrineCAD (catheter à demeure): indwelling (Foley) urine catheter, the most commonly used urine measurement in the ICU UrineUP (urethra praeter naturalis): urostomy.

The A/MCA/RA measurements were used for some specific ICU studies and views, so I would not recommend using them, and stick to the regular Kreatinine (bloed) measurements

Followup question - what is "UrineIncontinentie" in the context of urine output record? See here: https://github.com/AmsterdamUMC/AmsterdamUMCdb/blob/b88795565dae865869e6678c1d836e1e8200f41b/amsterdamumcdb/sql/common/urine_output.sql

Literally it means 'Urine incontinence'. Basically, it's a measurement (or estimation) of the urine output in patients that suffer from urine incontinence and for some rare reason do not have a Foley catheter. E.g. visual estimation of urine output or weighing of a medical diaper.

Thank you @patrickthoral! If I understand correctly, does it refer to the volume of urine output that wasn't collected using a tube into a container but instead leaked around and was estimated by the nursing staff?

Precisely!
