📋 Diagnosis: AKI is diagnosed if any ONE of:
① Serum creatinine ↑ ≥ 0.3 mg/dL within 48h
② Serum creatinine ↑ ≥ 1.5× baseline within 7 days
③ Urine output < 0.5 mL/kg/h for ≥ 6h

👤 Patient Information

Patient Weight *

Required for urine output calculation.

🧪 Serum Creatinine

Baseline Creatinine *

mg/dL

Known or presumed baseline creatinine within the last 7 days.

Current Creatinine *

mg/dL

Most recent serum creatinine value.

Time Since Baseline Creatinine * For diagnosis criteria: ≥ 1.5× baseline within 7 days, OR ≥ 0.3 mg/dL within 48h.

💧 Urine Output

Urine Output *

Total urine output over the specified time period.

Time Period * Time period over which urine output was measured.

⚕️ Renal Replacement Therapy

Patient is currently on Renal Replacement Therapy (RRT) If checked, automatically qualifies as Stage 3 AKI.

Pediatric patient (< 18 years) If checked, eGFR < 35 mL/min/1.73m² qualifies as Stage 3.

⚠️ Risk Factors (Optional)

Sepsis Hypotension Nephrotoxins Pre-existing CKD Diabetes Heart Failure Liver Disease

📖 KDIGO 2012 AKI Criteria:
Diagnosis: ↑ Creatinine ≥ 0.3 mg/dL within 48h OR ≥ 1.5× baseline within 7 days OR UO < 0.5 mL/kg/h for ≥ 6h.
Staging: Based on the more severe of creatinine OR urine output criteria.
Stage 3: ≥ 3× baseline OR ≥ 4.0 mg/dL OR RRT OR (pediatric) eGFR < 35 mL/min/1.73m².
