Table 1. Key characteristics of categorisations of the clinical scenarios tested
AKI severityKidney recoveryClinical historyManagement: next steps for rating

  • AKI stage 1

  • AKI stage 2

  • AKI stage 3

  • Good (serum creatinine within ≤25% above baseline)

  • Moderate (serum creatinine >25% and <50% above baseline)

  • Poor (serum creatinine ≥50% above baseline)

  • Chronic kidney disease

  • Chronic heart failure

  • Chronic heart failure with chronic kidney disease

  • Other significant cardiovascular risk factors

  • Markers of vulnerability

  • Markers of frailty

  • Determine appropriateness and timeliness in medication review

  • Determine appropriateness and timeliness in kidney monitoring for serum creatinine

  • Determine appropriateness and timeliness in kidney monitoring for proteinuria (urinary ACR)

  • ACR = albumin-to-creatinine ratio. AKI = acute kidney injury.
