The SUPPORT Physiologic Score needs to be calculated before the prognosis for a patient in the Intensive Care Unit can be determined.
Data:
• All data is from day 3 after admission, except for albumin.
• The albumin data used is from day 1.

where:
• Definitions for acute renal failure, multi-organ failure, and the other clinical conditions are available in Murphy and Cluff (1990; Chapter 3, pages 11S-28S)
• The WBC value is set to 9 if the WBC count is < 9,000 and the patient does not have ARF or MOSF. The WBC value is set to 40 if the WBC count is > 40,000.
• The creatinine value is set to 15 if creatinine is > 15.
• The value to use for the "APACHE III respiration score" is not precisely defined but is assumed to be based on the following score from APACHE III based on the respiratory rate.
respiratory rate in breaths per minute |
