Additional Info

• In original APACHE II there were no criteria given for what constitutes Acute Renal Failure. So, we came up with criteria based on serum creatinine and urine output. As we implemented ICD-10, we decided to use a uniform definition, i.e. the same one here as for the various ICD10 diagnoses of Acute Renal Failure -- i.e. the KDIGO guidelines.

Coding Guideline

For critical care only: The ARF (Acute Renal Failure) dropdown for APACHE defaults to "enter"; you won't be able to send unless you change it to one of the following:

• Choose "yes" if any one or more of the following are true (these are the KDIGO guidelines)KDIGO guidelines:
  • Increase in serum creatinine by 26 micromoles/L or more within 48 hours
  • Increase in serum creatinine to 1.5 times baseline or more within the last 7 days
  • Urine output less than 0.5 mL/kg/hour for 6 hours

Choose "no" if the pt

• has CRF in comorbids or
• does not meet the above "yes" conditions.

Data Use

ARF is one component used to generate the APACHE II score.

Specifically, double points are assigned for the Creatinine score if the patient has ARF . (see APACHE Scoring table#Physiological Variables)

CCMDB Data Integrity Checks

• Check ApARF CRF
