In the part of the U.K. that I live, the CC needs to be very accurate for cancer chemotherapy, it is therefore common practise for the patient to have an EDTA test - nuclear medicine. It seems differing practises in differing places.
Daily U&E's do still revolve around creatinine, for inpatients.
If eGFR is under 59 it will be stated in whole numbers.
ACR is done regularly for diabetics - NICE guidelines are issued.
AKI (prev aka acute renal failure,) "is now mostly based on monitoring creatinine levels," NICE.
Hope this may clarify.
