SOFA Score Calculator for Organ Failure Assessment
Instantly calculate the SOFA (Sequential Organ Failure Assessment) Score to evaluate the extent of organ dysfunction in critically ill patients.
See your SOFA score interpretation for Sequential Organ Failure Assessment.
This SOFA calculator is intended for clinical reference only and does not replace professional medical judgment or ICU assessment.
Sequential Organ Failure Assessment (SOFA) Score System
The Sequential Organ Failure Assessment (SOFA) score is used to quantify the severity of organ dysfunction in patients with suspected or confirmed sepsis and other critical illnesses.
It evaluates six organ systems:
- Respiratory
- Coagulation
- Liver
- Cardiovascular
- Central Nervous System
- Renel
The SOFA score helps clinicians:
- Assess severity of illness
- Monitor progression over time
- Predict mortality risk
- Identify worsening organ dysfunction
- Guide ICU decision-making
Each organ system is scored from 0 (normal function) to 4 (severe dysfunction).
How the SOFA Calculation Works
For each parameter selected, the calculator automatically assigns a score from 0 to 4 based on the severity of organ dysfunction.
The scoring scale generally represents:
- 0 - Normal organ function
- 1-2 - Mild to moderate dysfunction
- 3-4 - Severe organ dysfunction
The calculator then adds the scores from all six components to generate the total SOFA score instantly. This structured scoring approach helps clinicians quickly evaluate the extent of organ failure and track patient progression in critical care settings.

Frequently Asked Questions About SOFA Calculator
The SOFA calculator evaluates respiratory, coagulation, liver, cardiovascular, neurological, and renal parameters to assess organ dysfunction severity.
The calculator uses PaO₂/FiO₂ ratio, platelet count, bilirubin level, mean arterial pressure, Glasgow Coma Scale, and creatinine or urine output values.
The SOFA score helps clinicians assess organ failure progression, monitor patient deterioration, and support ICU decision-making during sepsis and critical illness management.
The system enables rapid organ dysfunction assessment and helps clinicians identify worsening sepsis conditions requiring escalation of care.
Yes. The system supports serial SOFA assessments, allowing clinicians to monitor changes in organ function across ICU and emergency care workflows.
MocDoc HMS automates organ system scoring and standardizes documentation workflows, reducing manual errors across hospital departments.
MocDoc HMS integrates SOFA scoring directly into ICU and emergency documentation workflows for centralized patient monitoring and organ dysfunction tracking.
The SOFA score evaluates six organ systems, each scored from 0 to 4: Respiratory (PaO₂/FiO₂), Coagulation (Platelets), Liver (Bilirubin), Cardiovascular (MAP/Vasopressors), Neurological (GCS), and Renal (Creatinine/Urine Output). Maximum total score = 24.
An increase of 2 or more SOFA points from baseline is associated with increased mortality risk in patients with suspected infection and may indicate worsening organ dysfunction requiring urgent intervention.
