Range 0 (best) to 24 (worst); generated using the worst physiological values during the first 3 days of hospitalisation.

*Defined as unanticipated ICU admission or in-hospital death.

†All patients who were admitted to the ICU survived hospitalisation.

‡Generated using the most abnormal values during the entire hospitalisation.

§Defined as discharge to higher level of care, hospice or in-hospital death.

ED, emergency department; ICU, intensive care unit; SOFA, Sequential Organ Failure Assessment score.
