Patients with haematological disorders have previously been considered to have poor outcomes following admission to intensive care units. Although a number of haematology centres from outside the UK have now demonstrated improved outcomes, the continuing perception of poor outcomes in this patient group continues to adversely affect their chances of being admitted to some intensive care units (ICUs). Over the past 10 years, there have been many advances within the disciplines of both haematology and intensive care medicine. This study was done to assess outcomes and the impact of an early warning scoring system (EWS) and early involvement of ICU outreach teams. One hundred five haematology patients (haematopoietic stem cell transplant (HSCT) or non-HSCT) had 114 admissions to ICU between April 2006 and August 2008 which coincided with hospital-wide implementation of EWS. The survival to ICU discharge was 56 (53%). Thirty-three (33%) patients were alive at 6 months giving a 1-year survival of 31%. Of the 39 HSCT patients, nine were post-autologous and 30 post-allogeneic transplant. The survival to ICU discharge was 22 (56%) with 14 (36%) patients alive at 6 months. One year survival was 36%. Prior to the introduction of EWS and critical care outreach team (2004), survival to ICU discharge was 44% which has increased to 53% (2006–2008). This is despite an increase in mechanical ventilation in 2006–2008 (50%) as compared to 2004 (32%).The improvement in ICU survivorship was even more prominent in HSCT patients (37% in 2004 versus 56% in 2006–2008). There was a trend towards decreasing Acute Physiology and Chronic Health Evaluation scores with time, suggesting appropriate patients being identified earlier and having timely escalation of their treatment.
