Os riscos envolvidos na transfusão de sangue e hemoderivados podem ser conseqüentes de procedimentos inadequados, erros ou omissões dos profissionais responsáveis pela transfusão. O presente estudo objetivou determinar o nível de conhecimento sobre o assunto e a adequação das práticas transfusionais dos profissionais de Enfermagem que atuam em um grande hospital universitário do interior de São Paulo. O estudo foi realizado durante um treinamento teórico em Hemoterapia, onde foi aplicado um instrumento de coleta de dados antes e após o treinamento, caracterizando estes profissionais e avaliando seus conhecimentos sobre o tema. Participaram enfermeiros, auxiliares e técnicos de enfermagem responsáveis pela administração de transfusões. Mais da metade se sente pouco ou mal informada sobre o assunto. Grande parte referiu que os pacientes não são orientados sobre sinais e sintomas de reações transfusionais, ainda referindo procedimentos incorretos para aquecimento do sangue. A avaliação de conhecimentos evidenciou lacunas importantes na capacitação destes profissionais. Rev. bras. hematol. hemoter. 2007;29(2):160-167.

BackgroundTo convert first-time blood donors into regular volunteer donors is a challenge to transfusion services.ObjectivesThis study aims to estimate the return rate of first time donors of the Ribeirão Preto Blood Center and of other blood centers in its coverage region.MethodsThe histories of 115,553 volunteer donors between 1996 and 2005 were analyzed. Statistical analysis was based on a parametric long-term survival model that allows an estimation of the proportion of donors who never return for further donations.ResultsOnly 40% of individuals return within one year after the first donation and 53% return within two years. It is estimated that 30% never return to donate. Higher return rates were observed among Black donors. No significant difference was found in non-return rates regarding gender, blood type, Rh blood group and blood collection unit.ConclusionsThe low percentage of first-time donors who return for further blood donation reinforces the need for marketing actions and strategies aimed at increasing the return rates.
Objective This study aimed to investigate the frequency of positive results for hepatitis B and C, HIV and syphilis in blood donations at the Centro Regional de Hemoterapia de Ribeirão Preto, to describe donors with positive results according to some demographic and socioeconomic variables, to identify risk factors associated to these donors and the reasons that they were not detected during clinical screening.
Methods A descriptive study was performed between July 1st 2005 and July 31st 2006 by interviewing 106 donorsafter medical consultations where they were informed of positive results for hepatitis B, hepatitis C, HIV or syphilis.
ResultsThere was a predominance of first-time donors, males, under 50-year olds, married individuals, from Ribeirão Preto, with elementary education, low economic status and of people who donated at the request of friends or relatives. Hepatitis C was the most frequently detected infection (56.6%), followed by hepatitis B (20.7%), HIV (12.3%) and syphilis(10.4%). About 40% of donors had omitted risk factors for different reasons: because they trusted the results of serological tests, did not feel comfortable about talking of risk factors or did not consider them relevant. Other justifications were the duration of the interview, the interviewer was unskilled, embarrassment and doubts about confidentiality.
Conclusion The results indicate the need for changes in the approach to clinical screening and a review of methods to attract and guide potential donors.
É comum afirmar-se que Clausewitz considerava a guerra como a continução da política por outros meios. Mais interessante, entretanto, é perceber que, para Clausewitz, são os objetivos políticos, mais do que os militares, que devem predominar na guerra. E é ainda mais importante perceber que aquilo que Clausewitz diz sobre a guerra é metodologicamente válido para a política, sobretudo para a conceituação do fato político.
