<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Introduction:  Anemia is a highly prevalent disorder. Preoperative anemia is associated with higher mortality, more complications, longer hospital stays, and higher healthcare costs. Red blood cell transfusion (RBC) does not improve these outcomes. The World Health Organization recommends implementing Patient Blood Management (PBM) programmes, as they can improve these clinical outcomes, reduce unnecessary RBC transfusions, and save costs. Despite compelling evidence, the implementation of these measures has yet to be effectively achieved. The objective of this study is to conduct a situational analysis to raise awareness about this issue and encourage the implementation of these measures.  Methodology: An observational, longitudinal, retrospective cohort study was conducted at a single center. All patients undergoing elective surgery from 01/01/2022 to 01/04/2022 at the Hospital de Clínicas were included. Exclusion criteria: absence of a complete blood count in the three months prior to surgery and refusal to participate in the study.  Results:  A total of 329 surgeries were analyzed. 52 out of 100 procedures were performed on patients with anemia. A statistically significant association was found between preoperative anemia and receiving RBC transfusion during hospitalization. OR 11.746 (4.518 - 30.540). Anemia and RBC transfusions significantly prolonged hospital stay. Length of hospitalization based on patient condition: No anemia: 10.1 ± 1.1 days, with anemia: 27.2 ± 2.3 days. Value of p &lt; 0.001. Non-transfused: 14.5 ± 1.3 days, transfused: 41.8 ± 4.4 days. Value of p &lt; 0.001. Only 49 (28.6%) of the 171 patients with anemia had iron metabolism assessed before surgery. Among the 140 patients with Hb &lt; 12 g/dL undergoing surgeries with non-insignificant bleeding, only 4 received specific treatment to optimize Hb. A total of 185 units of red blood cells (RBC) were administered during hospitalization. 49 to unstable patients (intraoperative or acute hemorrhage) and 136 to stable patients. From the analysis of the latter group, 42.5% of the patients received 3 or more RBC units. The average pre-transfusion hemoglobin was 7.0 ± 0.1. A statistically significant association was found between receiving RBC units and dying during hospitalization. OR 17.182 (3.360 - 87.872).  Conclusiones: A situational analysis was conducted, revealing a high prevalence of preoperative anemia, scarce study and treatment of anemia before surgeries, and an excessive amount of blood transfusions received by some patients. This work establishes the need to implement Patient Blood Management programs to reduce the prevalence of preoperative anemia and improve our transfusion practices. It also sets a comparative framework to evaluate the progress of these measures and indicates possible indicators to assess the benefits of their implementation.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo:  Introdução : A anemia é um distúrbio altamente prevalente. A anemia pré-operatória está associada a maior mortalidade, mais complicações, tempo prolongado de internação e maiores custos de saúde. A transfusão de glóbulos vermelhos (TGV) não melhora esses resultados. A Organização Mundial da Saúde recomenda a implementação de medidas de Gerenciamento de Sangue do Paciente (GSP), pois permitem melhorar esses resultados clínicos, reduzir TGV desnecessárias e economizar custos. Apesar da evidência contundente, a implementação dessas medidas ainda está aquém de ser efetivada. O objetivo deste trabalho é realizar uma análise da situação para conscientizar sobre o problema e incentivar a implementação dessas medidas.  Metodologia:  Foi realizado um estudo observacional, longitudinal, retrospectivo de coorte histórica, unicêntrico. Foram incluídos todos os pacientes submetidos a cirurgias de coordenação de 01/01/2022 a 01/04/2022 no Hospital de Clínicas. Critérios de exclusão: ausência de hemograma nos três meses anteriores à cirurgia e recusa em participar do estudo.  Resultados: Foram analisadas um total de 329 cirurgias. 52 a cada 100 procedimentos foram realizados em pacientes com anemia. Foi encontrada uma associação estatisticamente significativa entre a anemia pré-operatória e a recepção de TGR durante a internação. OR 11,746 (4,518 - 30,540). A anemia e as TGR prolongaram significativamente a internação hospitalar. Dias de internação em função da condição do paciente: Sem anemia: 10,1 ± 1,1 dias, com anemia: 27,2 ± 2,3 dias. Valor p &lt; 0,001. Não transfundidos: 14,5 ± 1,3 dias, transfundidos: 41,8 ± 4,4 dias. Valor p &lt; 0,001. Apenas 49 (28,6%) dos 171 pacientes com anemia tinham metabolismo do ferro antes da cirurgia. Dos 140 pacientes com Hb &lt; 12 mg/dL submetidos a cirurgias com sangramento não insignificante, 4 receberam tratamento específico para otimizar a Hb. Foram administradas um total de 185 unidades de glóbulos vermelhos (UGV) durante a internação. 49 em pacientes instáveis (intraoperatório ou hemorragia aguda) e 136 em pacientes estáveis. Da análise desses últimos, 42,5% dos pacientes receberam 3 ou mais UGV. A hemoglobina pré-transfusional média foi de 7,0 ± 0,1. Foi encontrada uma associação estatisticamente significativa entre receber UGV e falecer durante a internação. OR 17,182 (3,360 - 87,872).  Conclusões:  Foi realizado uma análise da situação na qual foi observada uma elevada prevalência de anemia pré-operatória, um estudo e tratamento escasso da anemia antes das cirurgias e uma quantidade excessiva de UGV recebidas por alguns pacientes. Este trabalho estabelece a necessidade de implementar programas de Gerenciamento de Sangue do Paciente para reduzir a prevalência de anemia pré-operatória e melhorar nossas práticas transfusionais. Além disso, estabelece um quadro comparativo para avaliar o progresso dessas medidas e aponta possíveis indicadores para avaliar os benefícios de sua implementação.]]></p></abstract>
