The Simplified Acute Physiology Score<unk> <unk>  is a system for predicting mortality, one of several ICU scoring systems. It is a supplement to the<unk> scoring system. It has been designed to provide a real-life predicted mortality for a patient by following a well defined procedure, based on a mathematical model that needs calibration. Predicted mortalities are good when comparing groups of patients, and having near-real-life mortalities means, that this scoring system can answer questions like "if the patients from hospital A had been in hospital B, what would their mortality have been?". However, in order to achieve this functionality, you must calibrate the system, which is additional effort, and it is difficult to compare two groups of patients if they were not scored using the same calibration.<unk>  is therefore not suitable by itself for publishing data about the morbidity of a single group of patients. The<unk>  project is conducted by the<unk>  Outcomes Research Group (SORG). Some shared calibrations make it possible to calculate a calibration-specific<unk>  score using paper forms.
