Model of Pohlen et al for Predicting Mortality of a Patient with Acute Myeloid Leukemia (AML) Admitted to the Intensive Care Unit (ICU)

Description

Pohlen et al developed a model for predicting mortality for a patient with acute myeloid leukemia (AML) who is admitted to the ICU. This can help to identify a patient who may benefit from admission to the ICU. The authors are from University Hospital Muenster in Germany.


 

Patient selection: AML admitted to ICU

 

Outcome: mortality in the ICU

 

Parameters:

(1) PaO2 in mm Hg on admission (hypoxemia)

(2) active AML on admission

(3) severe infection reason for ICU admission

(4) hemodialysis

(5) mechanical/invasive ventilation
