Template:ICD10 Guideline KDIGO Guidelines for Acute Renal Failure
This template contains the KDIGO guideline definition so it can be applied consistently everywhere it is used.

KDIGO Guidelines for Acute Kidney Injury (AKI)
- Starting January 1, 2019 when we began using ICD10 for diagnosis coding and CCI for procedure coding, we shifted to using the KDIGO criteria for defining Acute Kidney Injury -- which also goes by the names AKI, Acute Renal Failure and Acute Renal Insufficiency
- The main thing here is identifying that the observed problem with kidney function is acute, rather than chronic --- and THIS is the reason that identifying AKI requires trying to find a past/baseline value of serum creatinine
- These criteria will apply everywhere we need to identify ARF/AKI -- including Kidney, acute renal failure NOS and ARF (APACHE)
- In order to reduce the workload for identifying ARF/AKI, we will implement a first stage screening process to try and filter out the majority of people, who will NOT have AKI/ARF.
- We expect that this screening WILL miss a few people, but we also expect that most of those who are missed will continue to experience declining renal function and their AKI/ARF will be identified in the following days.
First stage - screening
- Assume at admission that the patient does NOT have AKI/ARF if ALLof the following are true:
- (1) Creatinine <110 for males and <90 for females AND
- (2) No mention in chart of acute kidney/renal problems AND
- (3) No mention in the chart of oliguria
- The source used for these threshold values of serum creatinine are population-based surveys of serum creatinine in people without known kidney problems:
- CA Jones et al. Serum creatinine levels in the US population: third National Health and Nutrition Examination Survey. Am J Kidney Dis 32(6):992-9, 1998
- JY Tiao et al. The effect of age on serum creatinine levels in an aging population: relevance to vascular surgery. Cardiovasc Surg 10(5):445-51, 2002
- If ANY of 1, 2 or 3 are false, then go on to the full evaluation in the Second Stage
Second stage - Full assessment
- Acute Kidney Injury (AKI) is present if ANY ONE OR MORE of the following are true (these are the KDIGO guidelines):
- (a) Urine output < 0.5 mL/kg/hour for 6 hours
- so, obviously, you can't make this determination until there has been at least 6 hours of observation of urine output
- also you need a weight -- if there isn't one already measured you have the following options: Wait for one to be done; Ask the nurse to do one; Use default values based on average values in the Canadian population, i.e. 85 kg for men and 70 kg for women
- (b) Increase in serum creatinine by 27 micromoles/L or more within 48 hours
- so, while this may happen quickly and thus this criterion be met, you cannot make the determination that it is NOT true until you have at least 2 serum creatinine values separated by at least 48 hours
- (c) Increase in serum creatinine to 1.5 times baseline or more within the last 7 days
- this criterion is important because many people have some degree of CHRONIC renal insufficiency or failure that a single serum creatinine can't tell you if the high value is acute or chronic
- thus, to evaluate this criterion, seek a serum creatinine value at least 7 days old -- use whatever is the most recent value available, even if it's old
- if there ARE NO values >7 days old, then you can use the sex-specific normal value as follows:
- MEN: 100 micromoles/L
- Women: 85 micromoles/L
