Implementation of a patient blood management program based on a low-income country-adapted clinical decision support system

ABSTRACT Introduction: Patient blood management (PBM) programs are associated with better patient outcomes, a reduced number of transfusions and cost-savings The Clinical Decision Support (CDS) systems are valuable tools in this process, but their availability is limited in developing countries This study assesses the feasibility and effectiveness of an adapted CDS system for low-income countries. Methods: This was a prospective study of the PBM program implementation, in a 200-bed tertiary hospital, between February 2019 and May 2020. Outcome measures were red blood cell (RBC), fresh frozen plasma (FFP) and platelet unit transfusions, the transfusion of a single unit of red blood cells and an RBC adequacy index (RAI). Results: Comparing the post-PBM program era with the pre-PBM system era, there was a decrease in red blood cell transfusions (p = 0.05), with an increase in single unit red blood cell transfusions (p = 0.005) and RAI (p < 0.001). Conclusions: The PBM programs, including electronic transfusion guidelines with pre-transfusion medical auditing, was associated with improved transfusion practices and reduced product acquisition-related costs.

Association of preoperative anemia and increased risk of blood transfusion and length of hospital stay in adults undergoing hip and knee arthroplasty: An observational study in a single tertiary center.

BACKGROUND AND AIMS: Anemia is a common feature in patients presenting for major elective surgery, and it is considered an independent risk factor associated with adverse outcomes. Although several studies suggest that preoperative anemia is associated with poor outcomes after elective orthopedic surgery, data are still scarce in middle- and low-income countries where this problem may be even greater. The objective of this study was to evaluate the impact of preoperative anemia in clinical outcomes in patients submitted to hip and knee arthroplasty in a single tertiary hospital. METHODS: Medical records of 234 adult patients submitted to knee and hip arthroplasty from January 2018 to July 2020 were retrospectively reviewed. Patient's demographics (ie, age and gender), pre- and postoperative hemoglobin level (Hb), allogeneic red blood cell (RBC) transfusion, intensive care admission, length of hospital stay, hospital readmissions, and mortality up to 30 days after the surgery were analyzed. Outcomes were evaluated according to preoperative anemia status based on World Health Organization (WHO) criteria. RESULTS: Mean age was 70 years with a slight female predominance (57.6%). The prevalence of anemia was 30.7% (72/234) being more prevalent in female (33.3% vs 26.7%). Preoperative anemia was significantly associated with greater rate of blood transfusion (34.5% vs 5.6%; P = .001), prolonged length of hospital stay (6.48 days vs 3.36 days; P = .001), and higher rate of intensive care unit admission (47.2% and 29.6% P = .009). Preoperative anemia had no effect on 30-day readmission and mortality for both males and females. CONCLUSIONS: Our retrospective study demonstrated that preoperative anemia is a common problem among orthopedic patients and is associated with increased transfusion risk and worse outcomes. Strategies to identify and treat anemic patients before elective surgery are critical to improving clinical outcomes.

Cost of chronic red blood cell transfusion in the Brazilian private healthcare sector from a payer perspective / Custo de transfusão crônica de concentrado de hemácias na perspectiva do sistema de saúde suplementar brasileiro

Objective: In the private healthcare sector in Brazil, the dearth of information regarding transfusion cost may compromise the management of conditions requiring long-term transfusion. Therefore, the present study aimed to estimate the cost of chronic red blood cell (RBC) transfusion in this context. Methods: A payer perspective was chosen for the analysis. A survey performed by an expert advisory board gathered information on the amounts reimbursed by health plans to blood centers per outpatient transfusion of a single RBC bag in multitransfused patients. Survey results were contrasted to RBC transfusion cost calculated using Brazilian Hierarchical Classification of Medical Procedures (CBHPM) parameters from 2018 and 2010, the latter suggested by the advisory board as more accurately reflecting market prices. Results: Six blood centers in the South and Southeast of Brazil were surveyed. The median amount reimbursed per RBC unit was R$ 1,066.44 (interquartile range: R$ 665.00-1,252.00). The mean amount reimbursed was R$ 959.54 ± R$ 337.14 (minimum: R$ 295.00 ­ maximum: R$ 1,980.00). Using 2018 CBHPM parameters, the cost of transfusing one RBC unit was calculated as R$ 1,905.18. Using 2010 CBHPM parameters, the cost was R$ 1,119.69 per RBC unit. Conclusions: Analyses using 2018 CBHPM parameters may lead to overestimation of transfusion cost. The best estimate for outpatient transfusion of one RBC bag in the private health care sector in Brazil lies between the observed reimbursed values and 2010 CBHPM cost. The present results provide valuable information for future cost-effectiveness analyses focusing on disorders whose treatment involves routine RBC transfusion.

A carência de informações sobre custo de transfusão sanguínea na saúde suplementar brasileira pode comprometer análises econômicas e eventuais decisões relacionadas a esse procedimento no longo prazo. O objetivo deste estudo foi estimar o custo de transfusão crônica de concentrado de hemácias (CH) nesse contexto. Métodos: Foi escolhida a perspectiva do pagador. Uma pesquisa foi realizada com especialistas para levantamento de valores reembolsados para transfusão de uma bolsa de CH em pacientes politransfundidos. Os resultados da pesquisa foram comparados ao custo de transfusão de CH calculado utilizando a Classificação Brasileira Hierarquizada de Procedimentos Médicos (CBHPM), edições de 2018 e 2010, sendo a edição mais antiga sugerida pelos especialistas como estando mais de acordo com a realidade de mercado. Resultados: Seis hemocentros localizados no Sul e Sudeste do Brasil foram incluídos. Os valores mediano e médio reembolsados aos hemocentros foram R$ 1.066,44 (amplitude interquartil: R$ 665,00-1.252,00) e R$ 959,54 ± R$ 337,14 (mínimo: R$ 295,00 ­ máximo: R$ 1.980,00), respectivamente. Com base nos parâmetros da CBHPM 2018 e 2010, os custos de transfusão calculados para uma bolsa de CH foram R$ 1.905,18 e R$ 1.119,69, respectivamente. Conclusões: Análises utilizando parâmetros da CBHPM 2018 podem superestimar os custos de transfusão de CH. Na perspectiva do sistema de saúde suplementar brasileiro, a melhor estimativa de custo de transfusão por bolsa de CH está entre o valor reembolsado e o valor calculado utilizando a CBHPM 2010. O presente estudo apresenta informações importantes para futuras análises de custo-efetividade de patologias que envolvem tratamentos à base de politransfusão de CH.

Brazilian experience using high dose sequential chemotherapy followed by autologous hematopoietic stem cell transplantation for malignant lymphomas

OBJECTIVE: To evaluate the use of high-dose sequential chemotherapy in a Brazilian population. METHODS: High-dose cyclophosphamide followed by autologous hematopoietic stem cell transplantation is an effective and feasible therapy for refractory/relapsed lymphomas; this regimen has never before been evaluated in a Brazilian population. All patients (106 with high-grade non-Hodgkin lymphoma and 77 with Hodgkin's lymphoma) submitted to this treatment between 1998 and 2006 were analyzed. Chemotherapy consisted of the sequential administration of high-dose cyclophosphamide (4 or 7 g/m²) and granulocyte-colony stimulating factor (300 µg/day), followed by peripheral blood progenitor cell harvesting, administration of etoposide (2g/m²) and methotrexate (8 g/m² only for Hodgkin's lymphoma) and autologous hematopoietic stem cell transplantation. RESULTS: At diagnosis, non-Hodgkin lymphoma patients had a median age of 45 (range: 8-65) years old, 78 percent had diffuse large B-cell lymphoma and 83 percent had stage III/IV disease. The Hodgkin's lymphoma patients had a median age of 23 (range: 7-68) years old, 64.9 percent had the nodular sclerosis subtype and 65 percent had stage III/IV disease. Nine Hodgkin's lymphoma patients (13 percent) and 10 (9 percent) non-Hodgkin lymphoma patients had some kind of cardiac toxicity. The overall survival, disease-free survival and progression-free survival in Hodgkin's lymphoma were 29 percent, 59 percent and 26 percent, respectively. In non-Hodgkin lymphoma, these values were 40 percent, 49 percent and 31 percent, respectively. High-dose cyclophosphamide-related mortality was 10 percent for Hodgkin's lymphoma and 5 percent for non-Hodgkin lymphoma patients. High-dose cyclophosphamide dosing had no impact on toxicity or survival for both groups. CONCLUSIONS: Despite a greater prevalence of poor prognostic factors, our results are comparable to the literature. The incidence of secondary neoplasias is noteworthy. ...

Transfusäo de hemacias contendo hemoglobina S / Erythrocyte transfusion with S hemoglobin

A incidência da presença de hemácias contendo Hemoglobina S em doadores de sangue brasileiros é representativa, chegando a 2,4 por cento caracterizando a necessidade potencial da sua detecçäo laboratorial a nível de triagem. A transfusäo destas hemácias pode resultar em efeitos indesejáveis, tanto pela possibilidade de falcizaçäo no receptor, como pelas lateraçöes do produto hemoterápico durante o processamento e estocagem. Estes säo os aspectos abordados nesta revisäo, sendo caracterizada a viabilidade da transfusäo autóloga ou homóliga das hemácias contendo hemoglobina S. Säo sugeridas modificaçöes nos protocolos de deglicerolizaçäo destes produtos, além da realizaçäo de testes pré-transfusionais para detecçäo da Hemoglobina S em algumas situaçöes de risco de falcizaçäo no receptor
