Impact of an Early Warning System on the Prognosis of Patients With Hematological Malignancies Receiving Intensive Chemotherapy With or Without Hematopoietic Cell Transplantation.

Patients with hematologic malignancies requiring intensive chemotherapy are at risk for life-threatening complications. Organ failure may appear rapidly and delay in initiating life-sustaining interventions may result in increased mortality. This encourages great alertness although not all patients require close monitoring. It is therefore critical to identify which patients are the most at risk for clinical deterioration to consider increased surveillance in these patients. The benefit of early intensive care unit (ICU) admission, as soon as the first signs of organ dysfunction appear, must also be clarified. Such an intervention could increase survival of patients by close monitoring and early initiation of organ-specific interventions but could also be responsible for anxiety and increased use of ICU resources. Many teams have analyzed the impact of early warning systems (EWS) includ
