Hammer et al reported the RISC score for predicting readmission of a surgical patient to the intensive care unit. The authors are from Beth Israel Deaconess Medical Center and Harvard Medical School.
The name RISC relates to the risk of readmission to the intensive care unit for a surgical critical care patient.
Parameters:
(1) sex
(2) surgical specialty
(3) hyperglycemia (> 180 mg/dL) within the past 24 hours
(4) severe anemia (< 7 g/dL) within the past 24 hours
(5) APACHE 2 score on admission
(6) positive fluid balance over ICU stay
(7) ambulation status within past 24 hours
(8) length of stay in ICU in days

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: -3
• maximum score: 13
• The higher the score the greater the risk of readmission to the ICU.
