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 : eg, 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.
