Impact of critical care outreach on hematopoietic stem cell transplant recipients: a cohort study.

摘要

Serious morbidity and mortality can occur after hematopoietic SCT (HSCT). Critical care outreach (CCO) can provide timely access to intensive care for hospitalized patients in need of urgent stabilization but has not been examined in HSCT. Rapid Assessment of Critical Events (RACE) team was introduced at our centre January 1, 2005. A retrospective cohort study was performed. Patients undergoing HSCT between January 1, 2000 and December 31, 2004 (n=520) formed the 'before' cohort and patients transplanted between January 1, 2005 and December 31, 2007 (n=294) formed the 'after' cohort. Non-relapse mortality at day 100 after transplant was not different in the two cohorts (26 (8.8%) post-RACE vs 53 (10.2%) pre-RACE, P=0.62). The number of failed organs at time of transfer to intensive care unit (ICU) was reduced in the post-RACE cohort (1.9 +/- 0.8 vs 2.3 +/- 1.0, P=0.04) and the incidence of cardiovascular failure was lower (23.8 vs 43.8%, P=0.04). Other secondary outcomes were not different, including the frequency of ICU admission. RACE may contribute to earlier stabilization during critical illness in patients undergoing HSCT but does not reduce non-relapse mortality. CCO should be studied prospectively in patients undergoing HSCT to better evaluate its role.
