Interactive Decision Tree
Algorithm Steps
- ▶Start
Acute Liver Failure
INR ≥1.5 + encephalopathy, no prior liver disease, <26 weeks
- ●Action
Initial Management
ICU admission, supportive care
- NAC if acetaminophen suspected
- ICP monitoring if grade 3-4 HE
- Coagulopathy management
- Etiology workup
- ◆Decision
Etiology
- Acetaminophen (APAP)
- Non-Acetaminophen (viral, autoimmune, drug, etc.)
- ●Action
Acetaminophen ALF
King's APAP criteria
- ◆Decision
APAP - King's Criteria
- pH <7.30 after resuscitation
- OR all 3: INR >6.5, Cr >3.4, Grade 3-4 HE
- ●Action
Meets Transplant Criteria
List for emergency transplant
- UNOS Status 1A listing
- Evaluate for contraindications
- Bridge therapies if needed
- ●Action
Liver Transplant
When organ available
- ■End
Outcome
Post-transplant care or recovery management
- ●Action
Does Not Meet Criteria
Continue supportive care, reassess
- Serial labs q6-12h
- May still need transplant if deteriorates
- Some recover spontaneously
- ●Action
Spontaneous Recovery
Monitor for complications
- ●Action
Non-Acetaminophen ALF
King's non-APAP criteria
- ◆Decision
Non-APAP - King's Criteria
- INR >6.5 regardless of HE grade
- OR 3 of 5: Age <10 or >40, non-A/non-B hepatitis, drug toxicity, jaundice >7d before HE, INR >3.5, Bili >17.5

Individual patient factors may require deviation from these recommendations.
Known Limitations
- King's criteria developed for acetaminophen - may differ for other etiologies
- Some patients recover without transplant despite meeting criteria
- Transplant availability affects utility
- MELD may complement but not replace King's
