SAPS II
SAPS II
SAPS II (pronounced: /sæps tuː/), an acronym for Simplified Acute Physiology Score II, is a severity score and mortality estimation tool developed in the field of intensive care medicine. It was first introduced in 1993 by Le Gall and colleagues.
Etymology
The term SAPS II is derived from the phrase Simplified Acute Physiology Score II. The 'II' signifies that it is the second version of the score, with the first version being the original SAPS.
Definition
SAPS II is a scoring system used to assess the severity of disease for patients admitted to Intensive care units (ICU). It is based on 17 variables: 12 physiological variables, age, type of admission (scheduled surgical, unscheduled surgical, or medical), and three underlying disease variables (AIDS, metastatic cancer, hematologic malignancy). Each variable is assigned a number of points, the sum of which gives the SAPS II score.
Related Terms
- Acute Physiology and Chronic Health Evaluation (APACHE II): Another widely used severity score in intensive care medicine.
- Sequential Organ Failure Assessment (SOFA): A scoring system used to track a patient's status during the stay in an ICU.
- Multiple Organ Dysfunction Score (MODS): A scoring tool used to quantify the degree of organ dysfunction in critically ill patients.
Usage
The SAPS II system is used worldwide in medical research and daily clinical practice. It helps in predicting the risk of mortality in ICU patients, guiding treatment decisions, and stratifying patients in clinical trials.
Limitations
While SAPS II is a valuable tool, it has limitations. It may not accurately predict mortality in certain subgroups of patients, such as those with severe sepsis or liver disease. It also does not account for the dynamic nature of illness severity in the ICU.
