RESUMO
BACKGROUND: We examined the association between social capital score, motivator factors and demographic and donation characteristics and donor return at three Brazilian blood centres in Recife, São Paulo and Belo Horizonte. MATERIAL AND METHODS: A total of 5974 donors were interviewed about motivation factors to donate and cognitive and structural social capital just before an effective donation in three Brazilians blood centres in 2009. We assessed the return to a new donation within 2 years for each of these donors. Demographic and donation characteristics, motivators and scores of social capital and their association with donors' return were assessed. RESULTS: Overall, 3123 (52.3%) of the study subjects returned for a blood donation at least once. Predictors of donors' return were male gender (adjusted odds ratio [AOR] = 1.6, 1.3-1.9, for replacement and AOR = 1.3, 1.2-1.6, for community donors), previous donation (AOR = 2.7, 2.3-3.3, for replacement and AOR = 2.9, 2.5-3.5, for community donors) and high altruism (AOR = 1.3, 1.1-1.7, for replacement and AOR = 1.2, 1.0-1.5, for community donors). Altruism was the only motivator associated with return behaviour. Donors from Recife and São Paulo were more likely to return for replacement and/or for community donations than donors from Belo Horizonte. There was no association between social capital score and donor return behaviour. CONCLUSION: The likelihood to return for a subsequent blood donation is dependent upon characteristics of individual donors and also varies in different regions of Brazil. However, social capital was not associated with the likelihood of return behaviour. A better understanding of altruistic categories and appeals may help to improve donor recruitment and retention.

INTRODUCTION: Hematologists deal every day with high mortality rates of acute leukemia patients. Many times these patients need Intensive Care Unit (ICU) support and some general ICU teams believe that these patients have a much greater chance of dying than patients with other pathologies. In Brazil, data related to mortality rates and ICUs for acute leukemia patients are scarce. METHODS: Therefore, to assess mortality predictors in patients with acute leukemia admitted to a specialized hematological ICU, we evaluated demographics, supportive care, hospitalization time, disease status, admitting diagnosis, neutropenia, number of transfusions and Acute Physiology and Chronic Health Evaluation (APACHE)/Sepsis Related Organ Failure Assessment (SOFA) scores as possible factors associated with mortality. Data were extracted from the first admission records of 110 patients with acute leukemia admitted to the Hemocentro de Pernambuco (Hemope) ICU between 2006 and 2009. RESULTS: In this retrospective cohort study, 72/110 of the patients were men, and 64/110 were from the metropolitan area of Recife. The patients' age median was 43.5 years (±17.9); 67.3% had acute myeloid leukemia (AML) and 32.7% had acute lymphoid leukemia. The main admitting diagnosis in the ICU was sepsis (66.7%). The mean APACHE II score was 18.3. Of the total, 65 (59%) died, and the mortality rate was independently related to longer hospitalization (p<0.001), the increase in the APACHE II score (p<0.038) and having received hemodialysis (p<0.006). Neutropenia, receiving multiple transfusions and using any kind of mechanical ventilation or vasoactive drug on admission were not relevant to mortality. Factors associated with higher mortality rates were: longer hospitalization, increase in the APACHE II score, and use of hemodialysis. CONCLUSION: With these data, to prevent organ lesions before admission to the ICU, a better strategy might be to reduce mortality for leukemia patients.
