Advice

If used in ICU patients, it is important to establish a baseline as soon as the patient arrives in the unit to allow assessment of score changes over the course of the illness.  

Management

Information gathered from this tool can be used to: 

  • Track disease progression.
  • Assess mortality risk.
  • Guide prognostic discussions with patients and their family members.
  • Support quality assessment.
  • Provide data for clinical trials. 
Critical Actions

Use clinical judgement to guide patient management, as this score does not validate the success or failure of a therapy.
