SAPS II

SAPS II or Simplified Acute Physiology Score II is a severity prediction score, used in the field of Intensive Care Medicine to determine the severity of disease for patients admitted to Intensive care units. It is a part of a class of disease severity scores, the first of which was the APACHE II score.

Overview[edit | edit source]

The SAPS II score was first developed in 1991 by Le Gall et al. It is calculated from 17 different variables, 12 of which are physiological measurements, and 5 of which are disease related. The score ranges from 0 to 163, with higher scores indicating more severe disease and higher risk of death.

Calculation[edit | edit source]

The SAPS II score is calculated from the worst values of the following variables in the first 24 hours of ICU admission:

Age
Heart rate
Systolic blood pressure
Temperature
Glasgow Coma Scale
Partial pressure of oxygen in arterial blood
Bicarbonate
Sodium
Potassium
Creatinine
Hematocrit
White blood cell count
Chronic diseases
Type of admission

Usage[edit | edit source]

The SAPS II score is used to predict mortality in ICU patients. It is also used in research to compare the outcomes of different patient groups, and to adjust for disease severity in statistical analyses.

Limitations[edit | edit source]

While the SAPS II score is widely used, it has some limitations. It does not take into account the progression of disease, and it may not be accurate for patients with certain conditions, such as those with human immunodeficiency virus (HIV) infection.
