  Raw score
  In statistics and data analysis, a raw score is an original datum that has not been transformed. This may include, for example, the original result obtained by a student on a test as opposed to that score after transformation to a standard score or percentile rank or the like.Often the conversion...

  Death is the termination of the biological functions that define a living organism. It refers to both a particular event and to the condition that results thereby. The true nature of the latter has for millennia been a central concern of the world's religious traditions and of philosophical...

  . In a rather simple way, it makes it possible to provide a single number that describes the morbidity of a number of patients.
• SAPS III
  SAPS III
  SAPS III is a system for predicting mortality, one of several ICU scoring systems. Its name stands for "Simplified Acute Physiology Score" and is a supplement to the SAPS II scoring system. It has been designed to provide a real-life predicted mortality for a patient by following a well defined...
  
   was designed to provide a realistic predicted mortality for a particular patient or a particular group of patients. It does this by calibrating
  Calibration
  Calibration is the set of operations that establish, under specified conditions, the relationship between the values of quantities indicated by a measuring instrument and the corresponding values realized by standards...
  
   against known mortalities on an existing set of patients, for a specific definition of mortality (like 30-days mortality). This way, it can answer questions like "Did we improve our quality of care from 2004 to 2005?" or "If hospital A's patients had been treated at hospital B, would they have a better or a worse mortality?".

Children scoring systems

• PIM2
  PIM2
  PIM2 is a scoring system for rating the severity of medical illness for children, one of several ICU scoring systems. Its name stands for "Paediatric Index of Mortality". It has been designed to provide a predicted mortality for a patient by following a well defined procedure...
  
   delivers a predicted mortality value, intended to be used for benchmarking.,

Other scoring systems

• SOFA
  SOFA Score
  The Sequential Organ Failure Assessment score, or just SOFA score, is used to track a patient's status during the stay in an intensive care unit . It is one of several ICU scoring systems....
  
   was designed to provide a simple daily score, that indicates how the status of the patient evolves over time.
• Glasgow Coma Scale
  Glasgow Coma Scale
  Glasgow Coma Scale or GCS, is a neurological scale which aims to give a reliable, objective way of recording the conscious state of a person, for initial as well as subsequent assessment...
  
   (also named GCS) is designed to provide the status for the central nervous system
  Central nervous system
  The central nervous system is the part of the nervous system that functions to coordinate the activity of all parts of the bodies of bilaterian animals—that is, all animals more advanced than sponges or jellyfish. In vertebrates, the central nervous system is enclosed in the meninges. It contains...
