Methodology · worked example, guidelines & full notes
Identify and treat precipitants (infection, GI bleed, constipation).
When to use
Assess and trend hepatic encephalopathy.
How it works
Grades 0 (minimal/covert) to 4 (coma); overt HE from grade 2.
Key points
- Identify and treat precipitants (infection, GI bleed, constipation).
- Grade 3–4 may need airway protection/ICU.
- Treatment: lactulose ± rifaximin.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Clinical grade | 2 — lethargy, disorientation to time, asterixis |

→West HavenGrade 2
- Note：Overt HE from grade 2; identify and treat precipitants (infection, GI bleed, constipation, electrolytes).
| Clinical grade | 0 (minimal) — no detectable change, abnormal on testing |

→West HavenGrade 0
- Note：Covert/minimal HE — consider specialised testing.

Frequently asked questions
- What are the limits and cautions when using West Haven Criteria (Hepatic Encephalopathy)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does West Haven Criteria (Hepatic Encephalopathy) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is West Haven Criteria (Hepatic Encephalopathy) calculated in practice? Can you show a worked example?
- Inputs: Clinical grade 2 — lethargy, disorientation to time, asterixis → Result: West Haven Grade 2（Note: Overt HE from grade 2; identify and treat precipitants (infection, GI bleed, constipation, electrolytes).） Inputs: Clinical grade 0 (minimal) — no detectable change, abnormal on testing → Result: West Haven Grade 0（Note: Covert/minimal HE — consider specialised testing.）
