SOFA Score Calculator

SOFA Score Calculator for Critical Care. Higher totals summarize greater scored organ dysfunction, without a fixed individual mortality percentage. A change from baseline requires clinical interpretation and infection context.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

The restored workflow adds six externally assessed original SOFA domain scores, each from 0 to 4, for a total from 0 to 24. It does not convert raw physiology to domain points. An optional documented baseline total yields current minus baseline.

When to use this calculator

Recording a completed original SOFA assessment, or comparing two compatible original SOFA totals.

Inputs used

  • Six externally assessed original SOFA domain scores, each 0-4
  • Optional documented baseline original SOFA total, 0-24

Clinical interpretation

Higher totals summarize greater scored organ dysfunction, without a fixed individual mortality percentage. A change from baseline requires clinical interpretation and infection context.

Worked example

Respiratory 3, coagulation 2, liver 2, cardiovascular 4, CNS 2 and renal 2 sum to 15. With documented baseline 3, the change is +12; this does not alone diagnose sepsis.

Limitations and safety notes

Physiology thresholds, exact ambiguous boundary conventions, support doses/duration and the observation window must be established using an authorized protocol outside this form. Full physiology-based restoration remains unresolved. This is not SOFA-2 and does not reproduce a licensed score table.

Frequently asked questions

Does this calculate SOFA directly from bilirubin or vasopressor dose?

No. It is explicitly a domain-score entry workflow. The earlier incomplete physiological bands have been removed, not declared validated.

What does this result leave unresolved?

Physiology thresholds, exact ambiguous boundary conventions, support doses/duration and the observation window must be established using an authorized protocol outside this form. Full physiology-based restoration remains unresolved. This is not SOFA-2 and does not reproduce a licensed score table.

  • Prefer original validation studies for scoring systems and prediction tools.
  • Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
  • Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
