Harrison et al developed a new model for predicting risk in a patient in the Intensive Care Unit (ICU). The authors are from the Intensive Care National Audit & Research Centre in London, Children’s Hospital Boston, the London School of Hygiene & Tropical Medicine and Broomfield Hospital in England.
Parameters:
(1) maximum heart rate in beats per minute
(2) minimum systolic blood pressure in mm Hg
(3) maximum temperature in °C
(4) minimum respiratory rate in breaths per minute
(5) PaO2 to FIO2 ratio and ventilation status (using minimum PaO2)
(6) minimum arterial pH
(7) maximum serum urea in mmol/L
(8) maximum serum creatinine in mg/dL
(9) maximum serum sodium in mmol/L
(10) 24 hour urine output
(11) minimum WBC count in 10^9/L
(12) sedated, paralyzed or Glasgow Coma score (GCS), with GCS determined during the first 24 hours after admission
