Stachon et al developed the Score for predicting mortality for a patient in the surgical intensive care unit. This can help to identify a patient who may benefit from more aggressive management. The authors are from Ruhr University in Bochum, Germany.
Parameters:
(1) ALT in IU/L
(2) C reactive protein in mg/dL
(3) total cholesterol in mg/dL
(4) serum creatinine in mg/dL
(5) creatinine kinase MB in U/L
(6) white blood cell count in 10^9/L
(7) potassium in mmol/L
(8) platelet count
(9) triglycerides in mg/dL
(10) age in years
