Missing Creatinine Measurement Values

[SAlkh90]

Hi

I have noticed that more than 3500 unique patients in eICU do not have any creatinine measurements within the first 48 hours of their ICU stay based on “labresultoffset”.

I am extracting the creatinine measurement from table “lab” with “labname” matching “creatinine” (ignoring case) based on the script in https://github.com/theonesp/aki_eicu/blob/master/analysis/sql/baseline_creat.sql

If this assertion is incorrect, where could the mistake lie? If the assertion is correct, what reasons lie behind so many patients not having creatinine measurements?

Thank you

The explanation is probably similar to https://github.com/MIT-LCP/mimic-code/issues/825#issuecomment-727620976 but there may be things in common about the patients that are missing observations (for example, the type of unit they were admitted to). This would need some exploration.
