The use of severity scores in the intensive care unit

  • Jean-Roger Le Gall


Around 1980 several intensivists decided to score the severity of ICU patients in order to compare the populations and evaluate the results. The outcome of intensive care depends on several factors present on the first day in the ICU and on the patient’s course under ICU therapy. The severity scores comprise usually two parts: the score itself and a probability model. The score itself is a number (the highest number, the highest severity). The probability model is an equation giving the probability of hospital death of the patients. This seminal comprise two parts: the classification of the scores and their practical use.
