    Abstract:
    The objectives of this study are to identify prognostic factors of survival to discharge in pediatric hematopoietic stem cell transplant (HSCT) recipients requiring intensive care unit (ICU) admission, and to determine the utility of the Oncological Pediatric Risk of Mortality (O-PRISM) in predicting death of these patients. A retrospective cohort of 125 pediatric HSCT recipients from October 1992 to September 2002 was analysed to evaluate risk factors of mortality in those admitted to ICU after HSCT. Nineteen patients (median age 7.8 years, 14 boys) required 24 ICU admissions post-HSCT. The most frequent underlying diseases were acute myeloid leukemia (n=5). The survival rate on discharge from ICU was 54%. In univariate analysis, risk factors of mortality included earlier requirement of ICU admission post-HSCT (median 34 versus 166 days, p=0.002), a longer delay before ICU admission (median 12 versus 5 h, p=0.02), lack of neutrophil (p=0.011) or platelet engraftment (p=0.008), macroscopic hemorrhage (p<0.001), tachypnoea (p=0.033), hypoxemia (p=0.031), renal impairment (p=0.011), coagulopathy (p=0.012), mechanical ventilation (p<0.001), and an increasing number of organ failures (p=0.003). Macroscopic hemorrhage and mechanical ventilation remained significant in multivariate analysis. Both PRISM and O-PRISM scores were significant composite prognosticators. It was concluded that mortality of post-HSCT children requiring ICU admission is high, especially in those with poor prognosticators.
