Background: Anemia remains one of the most common comorbidities in intensive care patients worldwide. The cause of anemia is often multifactorial and triggered by underlying disease, comorbidities, and iatrogenic factors, such as diagnostic phlebotomies. As anemia is associated with a worse outcome, especially in intensive care patients, unnecessary iatrogenic blood loss must be avoided. Therefore, this scoping review addresses the amount of blood loss during routine phlebotomies in adult (>17 years) intensive care patients and whether there are factors that need to be improved in terms of patient blood management (PBM). Methods: A systematic search of the Medline Database via PubMed was conducted according to PRISMA guidelines. The reported daily blood volume for diagnostics and other relevant information from eligible studies were charted. Results: A total of 2167 studies were identified in our search, of which 38 studies met the inclusion criteria (9 interventional studies and 29 observational studies). The majority of the studies were conducted in the US (37%) and Canada (13%). An increasing interest to reduce iatrogenic blood loss has been observed since 2015. Phlebotomized blood volume per patient per day was up to 377 mL. All interventional trials showed that the use of pediatric-sized blood collection tubes can significantly reduce the daily amount of blood drawn. Conclusion: Iatrogenic blood loss for diagnostic purposes contributes significantly to the development and exacerbation of hospital-acquired anemia. Therefore, a comprehensive PBM in intensive care is urgently needed to reduce avoidable blood loss, including blood-sparing techniques, regular advanced training, and small-volume blood collection tubes.

The Impact

Összefoglaló. Bevezetés: A COVID–19-világjárvány betegellátásra gyakorolt hatása hazánkban is jelentős. A vérellátást nehezítette a járványügyi intézkedések következményeként a véradási események elmaradása, a csökkent véradási hajlandóság, továbbá a nehezen megítélhető vérkészítményigény . A „Patient Blood Management” irányelveinek az orvosi gyakorlatban történő egyre szélesebb körű alkalmazása elősegíti az optimális vérkészítmény-felhasználást a transzfúziók lehetőség szerinti elkerülésével. Célkitűzés és módszer: Vizsgálatunk célja a Pécsi Tudományegyetem Klinikai Központjának Janus Pannonius Klinikai Tömbjében a vérkészítmény-felhasználás változásainak felmérése volt a 2020. év első öt hónapjában. Eredmények: A járványügyi intézkedéseket követő időszakban szignifikánsan csökkent a hospitalizált betegeknek (34,08%), a transzfúziót igénylő betegeknek (39,69%) és a felhasznált vörösvérsejt-készítményeknek (46,41%) a száma, valamint az egy betegre jutó felhasznált vörösvérsejt-koncentrátum átlaga (2,61-ről 1,97-re) is. Közel 30%-os arányban csökkent a felhasznált friss fagyasztott plazma egységeinek és a thrombocytakoncentrátumoknak a száma is. Következtetés: A szigorú korlátozások életbe léptetését követően a nehézségek ellenére sikerült elegendő mennyiségű vérkészítményt biztosítani a betegeknek. Az Országos Vérellátó Szolgálat Pécsi Regionális Vérellátó Központja munkatársainak és a klinikusok erőfeszítéseinek köszönhetően a vérkészítményigény és -kínálat között új egyensúly alakult ki, mely megfelelő ellátást biztosított a feltétlenül szükséges transzfúziók kivitelezéséhez. Orv Hetil. 2021; 162(43): 1717–1723. Summary. Introduction: The impact of COVID–19 pandemic on patient care is pronounced also in Hungary. Blood supply was hindered by the reduction of public blood donation events, the reduced willingness to donate, and the difficult predictability of blood product demand as a result of the epidemiological regulations. The wider application of Patient Blood Management guidelines in the medical practice will promote optimal blood product utilization by avoiding transfusions where possible. Objective and method: The aim of our study was to assess the changes in the usage of blood products in the first five months of 2020 at the Clinical Center of the University of Pécs, Janus Pannonius Clinical Building. Results: In the period following the epidemiological measures, we found reduction in the number of hospitalized patients (34.08%), in the number of patients requiring transfusion (39.69%) and in the number of red blood cell products used (46.41%). The number of transfused red blood cell concentrates per patient was also significantly reduced (from 2.61 to 1.97) in this period. The number of transfused fresh frozen plasma units and platelet concentrates also decreased by approximately 30%. Conclusion: After the implementation of the strict restrictions, despite the difficulties, it was possible to provide patients with sufficient blood products. Due to the efforts of both the Regional Blood Transfusion Center of Pécs of the Hungarian National Blood Transfusion Service and of the clinicians, a new balance was established between the demand and the supply of blood products, which provided adequate care for the necessary transfusions.

Implementation Framework

Abstract Background: Patient Blood Management (PBM) is an evidence-based approach in surgery and emergency care which aims to minimize the risk for blood loss and the need for blood replacement for each patient through a coordinated multidisciplinary care process before, during, and after surgery. In combination with blood loss, anemia is the main driver for transfusion and an independent risk factor for adverse outcomes including morbidity and mortality. Hence, identifying and correcting anemia as well as minimizing blood loss are important pillars of PBM. Evidence demonstrates that PBM significantly improves outcomes and safety while reducing cost by macroeconomic magnitudes. Despite its huge potential to improve healthcare systems, PBM is not yet adopted broadly. The aim of this study is to analyze the collective experiences of a diverse group of PBM implementors across countries reflecting different healthcare contexts and to use these experiences to develop a guidance for initiating and orchestrating PBM implementation for stakeholders from diverse professional backgrounds.Methods: Semi-structured interviews were conducted with 1-4 PBM implementors from 12 countries in Asia, Latin America, Australia, Central and Eastern Europe, the Middle East, and Africa. Responses reflecting the drivers, barriers, measures, and stakeholders regarding the implementation of PBM were summarized per country, and key observations extracted. By clustering the levels of intervention for PBM implementation, a PBM implementation framework was created and populated.Results: A set of PBM implementation measures were extracted from the interviews with the implementors. Most of these measures relate to one of six levels of implementation including government, healthcare providers, funding, research, training/education, and patients/public. Essential cross-level measures are multi-stakeholder communication and collaboration.Conclusion: This implementation framework helps to decompose the complexity of PBM implementation into concrete measures on each implementation level. It provides guidance for diverse stakeholders to independently initiate and develop strategies to make PBM a national standard of care, thus closing current practice gaps and matching this unmet public health need.

To verify whether low-dose aprotinin reduces blood loss and blood product usage in patients with clopidogrel exposure within 5 days before off-pump coronary artery bypass, 51 patients with clopidogrel exposure were randomized in a double-blind fashion to receive low-dose aprotinin (25 patients), or placebo (26 patients). The baseline characteristics and number of distal anastomoses in the patients in each group were comparable. Time between the last dose of clopidogrel and start of the operation was similar in both groups, as was mean left ventricular ejection fraction. Chest tube drainage, blood product usage, and reoperation rate were significantly higher in the placebo group. In patients with unstable angina and recent clopidogrel exposure who are undergoing off-pump coronary artery bypass, intraoperative administration of low-dose aprotinin is recommended to reduce blood loss and transfusion requirements.

Abstract Background: Patient blood management (PBM) programs aim to implement best practices and encourage blood stewardship. Judicious use of red blood cell transfusions improves patient safety, decreases hospital length of stay (LOS) and reduces cost. A 2010 World Health Organization statement asserted "…before surgery every reasonable measure should be taken to optimize the patient's own blood volume, minimize the patient's blood loss and to harness and optimize physiological tolerance of anemia…". A comprehensive PBM program includes a preoperative anemia clinic to facilitate these goals. At our institution, 21% of surgical patients are anemic prior to their elective surgery and these patients consume approximately 67% of our transfused operating room blood. Our aim was to reduce red blood cell transfusions in elective orthopedic surgical patients by 25% and decrease hospital LOS through the implementation of a preoperative anemia clinic. Methods: After enlisting the support of hospital leadership, a preoperative anemia clinic referral/consult order was added the electronic medical record. Appropriate patients for referral were undergoing elective orthopedic surgery and had anemia defined as a Hgb <11.0 g/dl. Additional non-anemic patients with extenuating circumstances such as religious objection to transfusion were also referred. Every effort was made to see patients at least 2 weeks prior to the date of scheduled surgery or within 48 hours if the referral was not placed that far in advance. Work-up of anemia was individualized based on a patient's laboratory abnormality and medical profile. Interventions were targeted at treating the underlying cause of anemia and included but were not limited to parenteral iron, erythropoietin receptor agonists, and vitamin B12 injections. The primary measures assessed were the average LOS from day of surgery to discharge and the number of red blood cell units transfused during that stay. Findings: Early data since implementing our preoperative anemia clinic has demonstrated a reduction in LOS from 5.5 days for anemic patients undergoing elective surgery without a referral versus 3.5 days for those with a referral. A relative decrease in LOS of 36%. Reductions in hospital LOS were observed across the spectrum of all elective surgical procedures. The overall red blood cell transfusion rate in patients without referral versus with referral was 1.5% and 1.2% respectively; and of those requiring a transfusion, the mean red blood cell units transfused in the perioperative period was 2.31 units versus 1.19 units, resulting in a relative reduction of 48%. Additionally, 2 patients were diagnosed with a gastric ulcer and 2 patients with multiple myeloma during work-up and referred appropriately for treatment. Discussion: Expansion of the PBM program at our institution to include a preoperative anemia clinic has led to significant reductions in both red blood cell transfusions and hospital LOS in elective orthopedic surgical patients. Early results indicate a near doubling of our goal of a 25% reduction in red blood cells transfused. This has positively impacted our patients and led to both direct and indirect financial savings at our institution. Given the initial success, we hope to expand our preoperative anemia clinic to include all surgical specialties and streamline workflow. To facilitate growth additional staffing will be required. We have created patient education videos about the benefits of correcting their anemia prior to an elective surgery and hope to further engage primary care practitioners to refer patients earlier in their surgical evaluation. We conclude that the creation of a preoperative anemia clinic at our institution is a valuable resource and has led to a decreased use of red blood cell transfusions, a decreased average hospital LOS, improved patient safety and considerable financial savings.

Fibrinogen Replacement Therapy

Major obstetric haemorrhage (MOH) is a leading cause of maternal death and morbidity, with the majority of deaths occurring within four hours of delivery. Therefore, prompt identification of women at risk of MOH is crucial for the rapid assessment and management of blood loss to urgently restore haemodynamic stability. Furthermore, as the rate of blood loss during MOH can increase rapidly in the time when laboratory results are awaited, the management of MOH could benefit from point-of-care coagulation testing by the ROTEM analyser which has a quicker turnaround time compared to standard laboratory coagulation tests. A number of studies indicate that ROTEM-based management of MOH has resulted in a significant reduction in massive transfusions and decreased transfusion of concentrated red cells (CRC) and fresh frozen plasma (FFP) due to a reduction in total blood loss. Several reports which have linked MOH to the depletion of fibrinogen reserves indicate that the reduction in CRC and FFP transfusions is largely due to an increase in early fibrinogen replacement therapy which corrects hypofibrinogenemia. This short report discusses preliminary findings on the impact of ROTEM point-of-care haemostasis analyser on the transfusion of various blood products to obstetric women experiencing MOH at the Royal Gwent Hospital in South wales. The number of blood products transfused following decisions based on the ROTEM analyser measurements (ROTEM group) was compared to historical transfusion data before the ROTEM analyser became available (Pre-ROTEM group). Blood product transfusion in the Pre-ROTEM group was guided by measurements of standard laboratory coagulation tests in conjunction with the established major haemorrhage protocols at the time. The findings indicate that the ROTEM analyser was effective in managing MOH at point-of-care and led to a reduction in the transfusion of CRC, FFP and platelets. However, contrary to published studies, the reduction in blood product usage was not accompanied by an increase in fibrinogen replacement transfusion therapy, suggesting that the ROTEM’s FIBTEM assay accurately quantified fibrinogen levels based on fibrin-clot firmness to enable an early diagnosis of hypofibrinogenemia. Early establishment of the absence of hypofibrinogenemia helped to prevent unnecessary transfusion of fibrinogen concentrate in this study. These findings support the adoption of routine use of ROTEM analysers at point-of-care on labour wards to manage MOH and reduce fibrinogen replacement therapy. The ease of use and rapidity of ROTEM tests could enable departure from globally directed correction of coagulopathy during MOH to a more focussed and precise target transfusion therapy, which will ultimately reduce blood product wastage (including fibrinogen concentrate) whilst minimising transfusion-associated side effects such as alloimmunisation, circulatory overload and dilutional coagulopathy.

Main Factors

Anemia, iron deficiency and other hematinic deficiencies are a major cause of perioperative transfusion needs and are associated with increased morbidity and mortality. Anemia can be caused either by decreased production of hemoglobin or red blood cells or by increased consumption and blood loss. Decreased production can involve anything from erythropoietin or vitamin B12 insufficiency to absolute or functional lack of iron. Thus, to achieve the goal of patient blood management, anemia must be addressed by addressing its causes. The traditional parameters to diagnose anemia, despite offering elaborate options, are not ideally suited to giving a simple overview of the causes of anemia, e.g., iron status for erythropoiesis, especially during the acute phase of inflammation, acute blood loss or iron deficiency. Reticulocyte hemoglobin can thus help to uncover the cause of the anemia and to identify the main factors inhibiting erythropoiesis. Regardless of the cause of anemia, reticulocyte hemoglobin can also quickly track the success of therapy and, together with the regular full blood count it is measured alongside, help in clearing the patient for surgery.
