transfusion practice variability

BACKGROUND: Blood loss during and after total knee arthroplasty (TKA) can lead to substantial morbidity and the need for blood transfusions. There are several methods to minimize blood loss and decrease transfusion rates in patients undergoing TKA. Tranexamic acid, an antifibrinolytic agent with known efficacy for achieving these goals, is combined with tourniquets to reduce bleeding in arthroplasty surgeries. Our study investigated the effects of various combinations of tranexamic acid and tourniquet use on bleeding in knee arthroplasty in 558 patients...

OBJECTIVES: We analyzed resuscitation practices in Cameroonian patients with trauma as a first step toward developing a context-appropriate resuscitation protocol. We hypothesized that more patients would receive crystalloid-based (CB) resuscitation with a faster time to administration than blood product (BL) resuscitation. METHODS: We included patients enrolled between 2017 and 2019 in the Cameroon Trauma Registry (CTR). Patients presenting with hemorrhagic shock (systolic blood pressure (SBP) <100 mm Hg and active bleeding) were categorized as receiving CB, BL, or no resuscitation (NR)...

BACKGROUND: Postoperative temperature dysregulation affects the length of hospital stay and prognosis. This study evaluated the factors that influence the occurrence of fever in patients after aortic valve replacement surgery. METHODS: Eighty-seven consecutive patients who underwent aortic valve replacement surgery were included. Patients' age, sex and body mass index; presence of diabetes mellitus; operation time; blood loss; blood transfusion volume; preoperative and postoperative laboratory findings; presence or absence of oral function management; and fever >38°C were retrospectively analysed through univariate and multiple logistic regression analyses...

BACKGROUND: Data examining the impact of sex on liver transplant (LT) outcomes are limited. It is clear that further research into sex-related differences in transplant patients is necessary to identify areas for improvement. Elucidation of these differences may help to identify specific areas of focus to improve on the organ matching process, as well as the peri- and post-operative care of these patients. AIM: To utilize data from a high-volume Eurotransplant center to compare characteristics of male and female patients undergoing liver transplant and assess asso ciation between sex-specific variables with short- and long-term post-transplant outcomes...

UNLABELLED: OBJECTIVE: Despite advances in perioperative care, hepatectomy remains associated with morbidity rates of up to 40%. Currently, available nomograms for predicting severe post-hepatectomy complications do not include early postoperative data. This retrospective observational study aimed to determine whether the parameters routinely measured in patients admitted to the Intensive Care Unit (ICU) after hepatectomy could represent risk factors for severe morbidity and to propose a nomogram scoring system to predict severe postoperative complications...

OBJECTIVE: To conduct a comprehensive multivariate analysis of variables associated with deep sternal wound infection, after open-heart surgery via median sternotomy. METHOD: A retrospective cohort of all adult patients, who underwent open-heart surgery at Odense University Hospital between 01-01-2000 and 31-12-2020 was extracted from the West Danish Heart Registry. Data were analyzed using maximum likelihood logistic regression. RESULTS: A total of 15,424 patients underwent open-heart surgery and 244 developed a deep sternal wound infection, equivalent to 1,58 %...

PURPOSE: There is significant variability in intraoperative red blood cell (RBC) transfusion practice. We aimed to use the theoretical domains framework (TDF) to categorize nonclinical and behavioural factors driving intraoperative RBC transfusion practice in a systematic review of the literature. SOURCE: We searched electronic databases from inception until August 2021 to identify studies evaluating nonclinical factors affecting intraoperative RBC transfusion. Using the Mixed Methods Appraisal Tool, we assessed the quality of included studies and identified relevant nonclinical factors, which were coded into TDF domains by two independent reviewers using NVivo (Lumivero, QSR International, Burlington, MA, USA)...

BACKGROUND: Blood transfusion is an effective therapeutic practice. However, even adopting all procedures for transfusion safety, there are risks, one of which is immediate adverse reactions. The aim of this study was, by active search, to evaluate the occurrence of immediate adverse reactions estimating the occurrence rate within the first 24 h. METHODS: An exploratory, descriptive, prospective study with quantitative analysis was carried out of patients undergoing surgery who received blood component transfusions during hospitalization from October 2018 to August 2019...

INTRODUCTION: The transfusion practice by surgery blood reserve, varied among services, must be performed through the rational and restrictive use of blood components because it is a scarce and expensive resource for health care services. OBJECTIVE: Analyze the use of blood products for surgery blood reserve by means of the study of the clinical-hematological profile of patients submitted to intraoperative and immediate postoperative transfusions. METHODS: This was an observational, cross-sectional, and retrospective study, conducted by collecting biological, operational, and laboratory variables, involving 680 patients at a university hospital who had elective surgery with surgery blood reserve request sent during the period from October 2021 to October 2022...

BACKGROUND: Randomized controlled trials relatively consistently show that restrictive red blood cell (RBC) transfusion strategies are safe and associated with similar outcomes compared to liberal transfusion strategies in critically ill patients. Based on these data, the general threshold for RBC transfusion was changed to 70 g/L at a 9-bed tertiary level intensive care unit in September 2020. Implementation measures included lectures, webinars and feedback during clinical practice...

BACKGROUND: Patient blood management (PBM) is an evidence-based approach recommended to improve patient outcomes. Change in practices is often challenging. We report here data from French surgical departments before and after a standardized implementation of a PBM program. METHODS: This was a national, multicenter, observational study in surgical centers ("expert" centers with an already established protocol for preoperative anemia or "pilot" centers). Data from consecutive surgical patients of different specialties were retrieved before and after the implementation of a PBM program...

The clinical application of cell therapies is becoming increasingly important for the treatment of cancer, congenital immune deficiencies, and hemoglobinopathies. These therapies have been primarily manufactured and used at academic medical centers. However, cell therapies are now increasingly being produced in centralized manufacturing facilities and shipped to medical centers for administration. Typically, these cell therapies are produced from a patient's own cells, which are the critical starting material...

BACKGROUND: Acute lower gastrointestinal bleeding (ALGIB) is a common cause of hospitalization. Recent guidelines recommend the use of prognostic scales for risk stratification. However, it remains unclear whether risk scores are more accurate than some simpler prognostic variables. OBJECTIVE: To compare the predictive values of haemoglobin alone and the Oakland score for predicting outcomes in ALGIB patients. DESIGN: Single-centre, retrospective study at a University Hospital...

OBJECTIVE: Wide interhospital variation exists in cardiac surgical postoperative transfusion rates. We aimed to compare transfusion rates at 2 hospitals and identify the institutional practice factors, unrelated to patient or operative characteristics, associated with postoperative transfusion rates. METHODS: Records for adult patients undergoing routine cardiac surgery at 2 hospitals (H and L) from February 2020 to August 2022 were analyzed. Patient and operative characteristics, preoperative and intensive care unit hemoglobin values, and postoperative transfusion rates were compared...

BACKGROUND: Although genetic polymorphism of the RH blood group system is well known in sub-Saharan Africa, national/regional specificities still remain to be described precisely. For the first time in Cameroon, Central Africa, and in order to better characterize the molecular basis driving RH phenotype variability, as well as to identify the main antigens that may be potentially responsible for alloimmunization, we sought 1) to study the RH genes in a cohort of 109 patients with sickle cell disease; 2) to study the same genes in the corresponding donors whose red blood cells (RBCs) were transfused to the patients (108 donors in 98 patients); 3) to predict RH phenotype on the basis of the molecular data and compare the results with serologic testing; and 4) to identify retrospectively patients at risk for alloimmunization...

BACKGROUND AND OBJECTIVE: Machine learning (ML) is a subset of artificial intelligence that uses data to build algorithms to predict specific outcomes. Few ML studies have examined percutaneous nephrolithotomy (PCNL) outcomes. Our objective was to build, streamline, temporally validate, and use ML models for prediction of PCNL outcomes (intensive care admission, postoperative infection, transfusion, adjuvant treatment, postoperative complications, visceral injury, and stone-free status at follow-up) using a comprehensive national database (British Association of Urological Surgeons PCNL)...

BACKGROUND: Sexually transmitted infections (STIs) are one of the major public health problems in India with adolescents being a vulnerable section of the affected population. According to the World Health Organization (WHO), one in twenty adolescents contracts an STI every year, excluding the human immunodeficiency virus (HIV) and other viral infections. It is important to assess the knowledge, attitude, and practices related to STIs among adolescents and young adults of non-medical backgrounds to educate them properly about protective and preventive measures and to allay misconceptions, if any...

In the field of blood and transfusion medicine, European Directorate for the Quality of Medicines & HealthCare recommends practices for metrological devices. Monitoring and measurement resources, as well as their permitted metrological limits, must be considered in this regard. We must understand variables such as metrological domains, the International System of Units, metrological traceability, and metrological requirements and controls in the field of transfusions in order to understand these metrological devices...

IMPORTANCE: There is marked variability in red blood cell (RBC) transfusion during the intraoperative period. The development and implementation of existing clinical practice guidelines have been ineffective in reducing this variability. OBJECTIVE: To develop an internationally endorsed consensus statement about intraoperative transfusion in major noncardiac surgery. EVIDENCE REVIEW: A Delphi consensus survey technique with an anonymous 3-round iterative rating and feedback process was used...

BACKGROUND AND OBJECTIVES: The practice regarding the selection and preparation of red blood cells (RBCs) for intrauterine transfusion (IUT) is variable reflecting historical practice and expert opinion rather than evidence-based recommendations. The aim of this survey was to assess Canadian hospital blood bank practice with respect to red cell IUT. MATERIALS AND METHODS: A survey was sent to nine hospital laboratories known to perform red cell IUT. Questions regarding component selection, processing, foetal pre-transfusion testing, transfusion administration, documentation and traceability were assessed...
