Scoring systems for ICU and surgical patients:

SAPS II (expanded)

Type of admission	Chronic diseases	Glasgow
Age	Syst. Blood Pressure	Heart rate
Temperature	If MV or CPAP PaO2/FIO2(mmHg)	Urine output
Serum Urea or BUN	WBC	Potassium
Sodium	HCO3 ^-	Bilirubin

Definitions

SAPS II =
(value may be entered directly)

Age	Sexe	Length of hospital stay before ICU admission
Patient's location before ICU	Clinical Category	Intoxication

SAPS II (expanded) =
(SAPS II (expanded) =0.0742*SAPS II + Sum of these six variables)

Predicted Mortality =

Logit= -14.4761+0,0844*SAPS II(expanded)+6.6158*log(SAPS II(expanded)+1)
Predicted Mortality =e^(Logit)/(1+e^(Logit))

Back to SAPS II

Definitions

Data are collected during the first 24 hours after ICU admission

Age
Use the patient's age in years at last birthday

Heart rate
Use the worst value in 24 hours, either low or high rate; if it varied from cardiac arrest (11pts) to extreme tachycardia (7pts), assign 11points.

SBP
Use the same method as for hearth rate : e.g., if it varied from 60 mmHg to 205 mmHg, assign 13 Points.

Body temperature
Use the highest temperature in °C or °F

PaO2/FiO2 ratio
If ventilated or CPAP, use the lowest value of the ratio.

Urinary output
If the patient is in the intensive care unit for less than 24 hours, make the calculation for 24 hours.

Serum urea or BUN
Use the highest value in mmol// or g/L for serum urea, in mg/dL for the serum urea nitrogen.

WBC count
Use the worst (high or low) WBC count.

Serum potassium level
Use the worst (high or low) value.

Serum Sodium level
Use the worst (high or low) value.

Serum bicarbonate level
Use the lowest value.

Bilirubin
Use the highest value in micromol/L or mg/dL

Glasgow coma score
Use the lowest value. If the patient is sedated, record the estimated Glasgow coma score before sedation.

AIDS
Yes, if HIV positive with clinical complications as pneumocystis carinii pneumonia, Kaposi's sarcoma, Lymphoma, tuberculosis or toxoplasma infection.

Hematologic malignancy
Yes, if lymphoma, acute leukemia, or multiple myeloma.

Metastatic cancer
Yes, if proven metastasis by surgery, C.T. scan or any other method.
