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
