The outcomes of 55 consecutive haemato-oncology patients admitted to the intensive care unit (ICU) were retrospectively analysed. Twenty-eight patients were admitted following haemopoietic stem cell transplantation (HSCT). Thirty-nine patients were admitted with respiratory failure, and all patients required respiratory support. Seventeen patients survived to be discharged from ICU, with an actuarial 1-year survival of 18%. Overall survival between patients who received intensive chemotherapy and those who underwent allogeneic HSCT was not significantly different (19% vs. 10%, P = 0.19). None of the nine myeloablative HSCT recipients survived (median survival: 9 d). Six of the 15 reduced-intensity conditioned HSCT recipients survived beyond 1 year (median survival: 1050 d, range: 438-1437).
