This template contains the KDIGO guideline definition so it can be applied consistently everywhere it is used.
To use:
- {{ICD10 Guideline KDIGO Guidelines for Acute Renal Failure}}
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
- (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 true, you cannot make the determination that this is NOT true until you have at least 2 serum creatinine values separated by at least 48 hours (sorry)
- (c) Increase in serum creatinine to 1.5 times baseline or more within the last 7 days
- this criterion is important because so 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 -- if the most recent value you can find is years ago, USE THAT
- if and only if you cannot find any values >7 days old, then you can use the age-specific normal value as follows:
M F
<45 101 81 45-54 101 84 55-64 101 84 65-74 101 87 75-84 106 91 85+ 108 93
- baseline in this case means most recent from more than 7 days ago; e.g. if last is from 5 months ago use that.
- if none available, use 88
- if weight not available, use
- ???also consider mention of obesity???
- wait for the weight
- ask ward nurses for weight
- use details
- 85kg for men
- 70kg for women
- if weight not available, use
