SAPS II is a severity of disease classification system. Its name stands for "Simplified Acute Physiology Score", and is one of several
ICU scoring systems.
Application
SAPS II was designed to measure the severity of disease for patients admitted to
Intensive care unit
An intensive care unit (ICU), also known as an intensive therapy unit or intensive treatment unit (ITU) or critical care unit (CCU), is a special department of a hospital or health care facility that provides intensive care medicine.
An inten ...
s aged 18 or more.
24 hours after admission to the ICU, the measurement has been completed and resulted in an
integer
An integer is the number zero (0), a positive natural number (1, 2, 3, ...), or the negation of a positive natural number (−1, −2, −3, ...). The negations or additive inverses of the positive natural numbers are referred to as negative in ...
point score between 0 and 163 and a predicted mortality between 0% and 100%. No new score can be calculated during the stay. If a patient is discharged from the ICU and readmitted, a new SAPS II score can be calculated.
This scoring system is mostly used to:
* describe the
morbidity
A disease is a particular abnormal condition that adversely affects the structure or function of all or part of an organism and is not immediately due to any external injury. Diseases are often known to be medical conditions that are asso ...
of a patient when comparing the outcome with other patients.
* describe the morbidity of a group of patients when comparing the outcome with another group of patients
Calculation
The point score is calculated from 12 routine physiological measurements during the first 24 hours, information about previous health status and some information obtained at admission.
The parameters are:
* Age
* Heart Rate
* Systolic Blood Pressure
*
Temperature
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measurement, measured with a thermometer. It reflects the average kinetic energy of the vibrating and colliding atoms making ...

Glasgow Coma Scale
The Glasgow Coma Scale (GCS) is a clinical scale used to reliably measure a person's level of consciousness after a brain injury.
The GCS assesses a person based on their ability to perform eye movements, speak, and move their body. These th ...

* Potassium
* Bicarbonate

The calculation method is optimized for paper schemas. In contrast to
APACHE II
APACHE II ("Acute Physiology and Chronic Health Evaluation II") is a severity-of-disease classification system, one of several ICU scoring systems. It is applied within 24 hours of admission of a patient to an intensive care unit (ICU): an in ...
, the resulting value is much better at comparing patients with different diseases .
The calculation method results in a predicted mortality, that is pure statistics. It does not tell the individual patient's chance of survival. The main purpose of this calculation is to provide a value that can be averaged for a group of patients, since it gives very unprecise values to calculate an average of the scores of a group of patients .
