Outcomes of non-COVID-19 critically ill patients with hematologic malignancies a 10-year single-center retrospective analysis

We report the outcomes of patients with haematological malignancies admitted to ICUs and define pre-ICU prognostic factors for in-hospital mortality. In a retrospective, single-center study, we included all patients with haematologic malignancies admitted to ICUs between 2009 and 2019. The primary outcome was in-hospital mortality. One hundred and forty-four patients with hematologic malignancies were admitted to ICUs during the study period. Fifteen (10.4%) were in remission, 36 (25.0%) were in remission after hematopoietic stem cell transplantation. Acute Leukemias and aggressive lymphomas were the most common diagnoses, occurring in 34.7%. The in-hospital mortality was 49%. The main predictors for in-hospital mortality were age >65 years, post allogeneic hematopoietic stem cell transplantation, non-remission, respiratory rate >22 bpm, bilirubin >2 mg/dl, PH< 7.35, and time from hospital admission to ICU transfer ≥3 days. In-hospital mortality of patients with hematologic malignancies admitted to ICU was 49%. We identified pre-ICU parameters that predict in-hospital mortality.
