Systematic Evaluation by an Intensivist of Hematological Malignancy Patients Presenting With Acute Respiratory or Hemodynamic Failure

Over the last two decades, the number of patients with hematological malignancies (HMs) admitted to the ICU increased and their mortality has dropped sharply. Patients with HMs increasingly require admission to the intensive care unit (ICU) for life-threatening events related to the malignancy and/or treatments, with immunosuppression being a major contributor. Whether the increase in ICU admissions is related to increased referrals by hematologists and/or to increased admissions by intensivists is unknown. The criteria used for ICU referral and admission decisions have not been extensively evaluated. Finally, the links between admission policies and treatment-limitation decisions are unclear, but ICUs with broad admission policies may change the treatment goals based on the response to several days of full-code management. The aim of this study is to evaluate the impact of a systematic evaluation by an intensivist of HMs patients presenting with acute respiratory and/or hemodynamic failure.
