AI Summary The SOFA score is an intensive care tool that rates how well several organ systems are working, helping liver teams see how far a serious illness has spread beyond the liver. In acute-on-chronic liver failure (ACLF), the kidneys are the organs outside the liver most often affected. SOFA does not diagnose a condition or predict outcome alone, so teams also use ACLF-specific scores, and care focuses on organ support, treating the trigger, and transplant evaluation.

The SOFA score is a tool used in intensive care. SOFA stands for Sequential Organ Failure Assessment. It helps the care team describe how many organs are affected by a serious illness and how badly.
In people with liver disease, a severe illness often reaches beyond the liver. The kidneys, brain, lungs, and circulation can be affected too. That is why liver teams look at organ function as a whole.
This page explains what a SOFA score is for, how it differs from related scores, and what to ask your ICU and liver team.

ABOUT THE SOFA SCORE
The SOFA score (Sequential Organ Failure Assessment) is a scoring tool from intensive care medicine. It rates how well several organ systems are working, so the team can see how widespread a critical illness is.
This matters in liver disease. When chronic liver disease worsens suddenly, the liver can fail and other organs can fail with it. This is called acute-on-chronic liver failure (ACLF). Four organ systems outside the liver can fail: the brain, the circulation, the lungs, and the kidneys.
SOFA is not the same as qSOFA (quick SOFA). qSOFA is a short bedside screen for people with suspected infection. It has been validated in people with cirrhosis.
A SOFA score does not diagnose a condition, and it does not replace your doctors' judgment. This page does not include the scoring table or cutoffs. Your care team can explain which results they used and what your number means.
WHY IT MATTERS IN LIVER DISEASE
In a liver crisis, the liver is only part of the picture. Organs outside the liver often shape the outcome, so liver teams watch them closely.
In acute-on-chronic liver failure, doctors see liver failure, shown by high bilirubin and a high INR (a clotting test). They also see failure of at least one other organ: the brain, circulation, lungs, or kidneys. A rapid decline marks the syndrome.
Kidney failure, or acute kidney injury (AKI), is the most common organ failure outside the liver in ACLF. Reported rates vary widely, from 29% to 75% under some definitions and 6% to 28% under stricter ones. It is more common when an infection triggers ACLF.
In people with cirrhosis, organ failures outside the liver raise the risk of death, lengthen hospital stays, and increase the use of hospital resources. Hospital teams need to spot and manage organ problems early.
COMPARE SCORES
Each score answers a different question. Your team may use more than one.
| Score | What It Is Used For | What to Know |
|---|---|---|
| SOFA | Describes how well several organ systems are working in severe illness | A general ICU score. It is not specific to liver disease. |
| qSOFA | Quick bedside screen in people with suspected infection | Validated in cirrhosis. It predicts hospital death better than SIRS criteria. |
| CLIF-C ACLF | Judges short-term outlook in acute-on-chronic liver failure | An ACLF-specific score. See our CLIF-C ACLF Score page. |
| MELD and MELD-Na | Estimate liver disease severity and help set transplant priority | Conventional cirrhosis scores often underestimate death risk in ACLF because they miss organ failures outside the liver. |
This table describes purpose only. Scoring tables and cutoffs are set by the published tools, and your care team applies them.
LIMITS OF THE SCORE
A score reflects the test results and exam findings available when it was calculated. For ACLF, repeated assessments of outlook are recommended rather than one score. A number that changes over days shows how you are responding.
A score does not tell the team why organs are failing. Doctors look for a trigger, such as infection, and they treat it. In some people with ACLF, no clear trigger is found.
Doctors read any score with your exam, labs, medical history, and goals. If you or a family member sees a score, ask the team to explain which results were used and what they mean for your care.
CARE IN THE ICU
There is no single treatment tied to a SOFA number. Care depends on the cause and on which organs are affected.
ACLF is a critical syndrome that needs intensive care. Early recognition, organ support, and an evaluation for liver transplantation are all essential, because the illness can worsen quickly.
Infection can trigger organ failure in people with cirrhosis. Sepsis care in the ICU includes antibiotics, measures to stabilize blood pressure, and sometimes surgery to remove the source of infection.
Some people receive temporary extracorporeal liver support, which filters the blood outside the body. It may serve as a rescue therapy or a bridge to transplant in selected people with severe liver failure.
Malnutrition and frailty are common in chronic liver disease. Nutrition often gets worse during a long ICU stay, so nutrition assessment and support are part of care.

Common Questions
The SOFA score is an intensive care tool that rates how well several organ systems are working. SOFA stands for Sequential Organ Failure Assessment. Doctors use it to describe how widespread a serious illness is and to follow changes over time. This matters in liver disease because a severe illness often reaches beyond the liver to the kidneys, brain, lungs, and circulation. This page does not include the scoring table, so ask your care team which results they used.
No. SOFA is a general ICU score and does not diagnose a liver condition. Doctors diagnose acute-on-chronic liver failure (ACLF) in a person with chronic liver disease who has liver failure, shown by high bilirubin and a high INR (a clotting test), plus failure of at least one other organ. That organ may be the brain, circulation, lungs, or kidneys. A rapid decline marks the syndrome. A SOFA score can describe how many organs are affected, but your doctors make the diagnosis from the full picture.
No. SOFA rates several organ systems and describes how well each one is working. qSOFA (quick SOFA) is a short bedside screen for people with suspected infection. It has been validated in people with cirrhosis, and it predicts hospital death more accurately than older SIRS criteria. A positive qSOFA in a person with cirrhosis and infection points to a poor outcome and should prompt immediate thought about moving the person to an ICU. The two scores do different jobs, and your team may use more than one.
Not on its own. A score reflects the results and exam findings available when it was calculated, so it describes one moment. For ACLF, repeated assessments of outlook are recommended rather than a single score. ACLF-specific scores, such as CLIF-C, NACSELD, and AARC, are recommended because they count organ failures outside the liver. Conventional cirrhosis scores, such as MELD, often underestimate death risk in ACLF for the same reason. Your team reads any score with your exam, labs, and response to treatment.
Ask which results were used and what the number means for your family member's care. Also ask how often the score will be rechecked, since trends matter more than one value. A number that changes over days shows how the person is responding. You can ask which other scores the team uses and which organs are being supported. Ask for the answers in plain language, and have someone write them down.
