Calculate SOFA organ dysfunction score and an APACHE II style severity total.
SOFA describes concurrent organ dysfunction and is most informative as a trend over days rather than as a single value. Rising SOFA scores predict outcome better than the admission value alone. These scores were developed for cohort comparison rather than individual prognosis, and applying population mortality to one patient is a recognised misuse.
APACHE II / SOFA Score
SOFA sums six organ systems scored 0 to 4 each, giving 0 to 24
This reproduces a published formula for educational and reference use only. It is not a diagnostic tool, does not account for individual clinical context, and must not be used to make or change treatment decisions. Clinical assessment by a qualified healthcare professional is always required. These are intensive care research and audit instruments requiring detailed physiological data. They are not intended for individual prognostication or for use outside critical care by non-specialists.

This calculator takes 8 inputs: Respiration component, Coagulation component, Liver component, Cardiovascular component, Central nervous system component, Renal component, APACHE II age points, APACHE II chronic health points. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
