Validation of the REDS score in hospitalised patients who deteriorated and were admitted to the intensive care unit-a retrospective cohort study.

Background: Hospitalised patients are at risk of deterioration and death. Delayed identification and transfer to the intensive care unit (ICU) are known to be associated with increased mortality rates. The Risk-stratification of Emergency Department suspected Sepsis (REDS) score was derived and validated in emergency department patients with suspected sepsis.
