Abstract
INTRODUCTION Preparing appropriate red blood cells (RBCs) before surgery is crucial for improving both the efficacy of perioperative workflow and patient safety. In particular, thoracic surgery (TS) is a procedure that requires massive transfusion with high variability for each patient. Hence, the precise prediction of RBC requirements for individual patients is becoming increasingly important. This study aimed to 1) develop and validate a machine learning algorithm for personalized RBC predictions for TS patients and 2) assess the usability of a clinical decision support system (CDSS) integrating this artificial intelligence model. METHODS Adult patients who underwent TS between January 2016 and October 2021 were included in this study. Multiple models were developed by employing both traditional statistical- and machine-learning approaches. The primary outcome evaluated the model's performance in predicting RBC requirements through root mean square error and adjusted R2. Surgeons and informaticians determined the precision MSBOS-Thoracic Surgery (pMSBOS-TS) algorithm through a consensus process. The usability of the pMSBOS-TS was assessed using the System Usability Scale (SUS) survey with 60 clinicians. RESULTS We identified 7,843 cases (6,200 for training and 1,643 for test sets) of TSs. Among the models with variable performance indices, the extreme gradient boosting model was selected as the pMSBOS-TS algorithm. The pMSBOS-TS model showed statistically significant lower root mean square error (mean: 3.203 and 95% confidence interval [CI]: 3.186-3.220) compared to the calculated Maximum Surgical Blood Ordering Schedule (MSBOS) and a higher adjusted R2 (mean: 0.399 and 95% CI: 0.395-0.403) compared to the calculated MSBOS, while requiring approximately 200 fewer packs for RBC preparation compared to the calculated MSBOS. The SUS score of the pMSBOS-TS CDSS was 72.5 points, indicating good acceptability. CONCLUSIONS We successfully developed the pMSBOS-TS capable of predicting personalized RBC transfusion requirements for perioperative patients undergoing TS.

Abstract
One of the target of perioperative tratment in surgery is decreasing intraoperative bleeding, which increases the number of perioperative procedures, mortality and treatment costs, and also causes the risk of transfusion of blood and its components. Trying to minimize the blood loss(mainly during the operation) as well as the need to transfuse blood and its components (broadly understood perioperative period) should be standard treatment for a patient undergoing a procedure. In the case of this method, the following steps should be taken: 1) in the preoperative period: identyfication of risk groups as quickly as possible, detecting and treating anemia, applying prehabilitation, modyfying anticoagulant treatment, considering donating one's own blood in some patients and in selected cases erythropoietin preparations; 2) in the perioperative period: aim for normothermia, normovolemia and normoglycemia, use of surgical methods that reduce bleeding, such as minimally invasive surgery, high-energy coagulation, local hemostatics, prevention of surgical site infection, proper transfusion of blood and its components if it occurs; 3) in the postoperative period: monitor the condition of patients, primarily for the detection of bleeding, rapid reoperation if required, suplementation (oral administration preferred) nutrition with microelements (iron) and vitamins, updating its general condition. All these activities, comprehensively and in surgical cooperation with the anesthesiologist, should reduce the blood loss and transfusion of blood and its components.

Effect of Perioperative Blood Transfusions and Infectious Complications on Inflammatory Activation and Long-Term Survival Following Gastric Cancer Resection. Cancers (Basel) 2022; 15:cancers15010144. [PMID: 36612141 PMCID: PMC9818188 DOI: 10.3390/cancers15010144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 12/23/2022] [Indexed: 12/28/2022] Open
Abstract
Background: The aim of this study was to evaluate the impact of perioperative blood transfusion and infectious complications on postoperative changes of inflammatory markers, as well as on disease-free survival (DFS) in patients undergoing curative gastric cancer resection. Methods: Multicenter cohort study in all patients undergoing gastric cancer resection with curative intent. Patients were classified into four groups based on their perioperative course: one, no blood transfusion and no infectious complication; two, blood transfusion; three, infectious complication; four, both transfusion and infectious complication. Neutrophil-to-lymphocyte ratio (NLR) was determined at diagnosis, immediately before surgery, and 10 days after surgery. A multivariate Cox regression model was used to analyze the relationship of perioperative group and dynamic changes of NLR with disease-free survival. Results: 282 patients were included, 181 in group one, 23 in group two, 55 in group three, and 23 in group four. Postoperative NLR changes showed progressive increase in the four groups. Univariate analysis showed that NLR change > 2.6 had a significant association with DFS (HR 1.55; 95% CI 1.06−2.26; p = 0.025), which was maintained in multivariate analysis (HR 1.67; 95% CI 1.14−2.46; p = 0.009). Perioperative classification was an independent predictor of DFS, with a progressive difference from group one: group two, HR 0.80 (95% CI: 0.40−1.61; p = 0.540); group three, HR 1.42 (95% CI: 0.88−2.30; p = 0.148), group four, HR 2.85 (95% CI: 1.64−4.95; p = 0.046). Conclusions: Combination of perioperative blood transfusion and infectious complications following gastric cancer surgery was related to greater NLR increase and poorer DFS. These findings suggest that perioperative blood transfusion and infectious complications may have a synergic effect creating a pro-inflammatory activation that favors tumor recurrence.

Abstract
The use of Intraoperative Cell Salvage (ICS) is currently limited in oncological surgeries, due to safety concerns associated with the ability of existing devices to successfully remove circulating tumour cells. In this work, we present the first stages towards the creation of an alternative platform to current cell savers, based on the extremely selective immunoaffinity membrane chromatography principle. Non-woven membranes were produced via electrospinning using poly(vinyl alcohol) (PVA), and further heat treated at 180 °C to prevent their dissolution in aqueous environments and preserve their fibrous morphology. The effects of the PVA degree of hydrolysis (DH) (98 % vs 99 %), method of electrospinning (needleless DC vs AC), and heat treatment duration (1-8 h) were investigated. All heat treated supports maintained their cytocompatibility, whilst tensile tests indicated that the 99 % hydrolysed DC electrospun mats were stronger compared to their 98 % DH counterparts. Although, and at the described conditions, AC electrospinning produced fibres with more than double the diameter compared to those from DC electrospinning, it was not chosen for subsequent experiments because it is still under development. Evidence of unimpeded passage of SY5Y neuroblastoma cells and undiluted defibrinated sheep's blood in flow-through filtration experiments confirmed the successful creation of 3D networks with minimum resistance to mass transfer and lack of non-specific cell binding to the base material, paving the way for the development of novel, highly selective ICS devices for tumour surgeries.

Abstract
Patient blood management (PBM) offers significantly improved outcomes for almost all medical and surgical patient populations, pregnant women, and individuals with micronutrient deficiencies, anemia, or bleeding. It holds enormous financial benefits for hospitals and payers, improves performance of health care providers, and supports public authorities to improve population health. Despite this extraordinary combination of benefits, PBM has hardly been noticed in the world of health care. In response, the World Health Organization (WHO) called for its 194 member states, in its recent Policy Brief, to act quickly and decidedly to adopt national PBM policies. To further support the WHO's call to action, this article addresses 3 aspects in more detail. The first is the urgency from a health economic perspective. For many years, growth in health care spending has outpaced overall economic growth, particularly in aging societies. Due to competing economic needs, the continuation of disproportionate growth in health care spending is unsustainable. Therefore, the imperative for health care leaders and policy makers is not only to curb the current spending rate relative to the gross domestic product (GDP) but also to simultaneously improve productivity, quality, safety of patient care, and the health status of populations. Second, while PBM meets these requirements on an exceptional scale, uptake remains slow. Thus, it is vital to identify and understand the impediments to broad implementation. This includes systemic challenges such as the so-called "waste domains" of failure of care delivery caused by malfunctions of health care systems, failure of care coordination, overtreatment, and low-value care. Other impediments more specific to PBM are the misperception of PBM and deeply rooted cultural patterns. Third, understanding how the 3Es-evidence, economics, and ethics-can effectively be used to motivate relevant stakeholders to take on their respective roles and responsibilities and follow the urgent call to implement PBM as a standard of care.

Abstract
Background Packed red blood cell (RBC) transfusion is a very common and frequently lifesaving therapeutic intervention, but a liberal transfusion policy may be associated with inferior patient outcomes. Various guidelines have been proposed to reduce the rate of unnecessary RBC transfusions. However, physicians' proficiency in such guidelines and the effect of training on RBC administration remain unknown. Methods We performed a questionnaire‐based assessment of physicians' knowledge of the guidelines in a tertiary hospital in Israel, followed by an analysis of RBC administration six months before and six months after training was delivered. Results The level of proficiency was higher among Israeli university graduates (Odds Ratio [OR] 2.59, p‐value = 0.02), internists (OR 2.8, p‐value = 0.02), and physicians beyond the step‐one residency exam (OR 3.08, p‐value = 0.02). There was no significant effect of training on the rates of RBC administration (incidence rate ratio [IRR] = 0.96 [CI 95% 0.81–1.14], p‐value = 0.655). Conclusion Educational intervention alone is an ineffective means of reducing the rates of RBC administration. A more complex approach is required to prevent unnecessary RBC transfusions.

Abstract
Cardiac surgery is typically attributed with a significant risk of intraoperative blood loss and allogeneic blood transfusions. Intraoperative blood loss, allogenic blood transfusions, high dose anticoagulation requirement, and interactions with cardiopulmonary bypass (CPB) have all been linked to cardiac surgeries. To reduce unnecessary transfusions and their negative effects, it is recommended to follow evidence-based multidisciplinary strategies, which are collectively termed patient blood management (PBM). This review highlights the most recent blood conservation strategies in adult cardiac surgery, which can be employed pre-operatively, intra-operatively, and postoperatively, to enhance red cell mass and attenuate the utilization of packed red blood cells (PRBCs) and other blood products.

Abstract
BACKGROUND Anemia is a frequent process of morbidity and mortality in body contouring procedures. In aesthetic surgery, there are no standardized processes to minimize bleeding during surgery. For this reason, a study was designed to implement patient blood management strategies to reduce bleeding and transfusions in patients undergoing body contouring operations. METHODS From January of 2017 to May of 2018, a prospective cohort-type observational study was conducted, including two groups of patients undergoing single or combined body contouring procedures. The first group did not receive patient blood management strategies, whereas the second group did receive these strategies. These measures consisted of preoperative strategies to ensure the patient had optimal hemoglobin and hematocrit levels and supportive intraoperative measures to minimize blood loss. The results were validated with different statistical tests according to the variables studied. RESULTS A total of 409 patients were included in the study and were divided into two groups. The anthropometric and hemoglobin variables were similar in both groups. The 207 patients for whom patient blood management strategies were implemented lost an average of 1.2 g/dl less hemoglobin at 72 hours than the 202 patients for whom patient blood management strategies were not implemented (p ≤ 0.0001). CONCLUSIONS Patient blood management strategies, such as increasing hemoglobin before surgery, and strategies to minimize blood loss during surgery, proved to be effective at reducing bleeding in patients undergoing body contouring surgery, also decreasing the need to perform postoperative blood transfusions.

OBJECTIVES Our aim was to assess blood utilization after implementation of a patient blood management (PBM) program in a Greek tertiary hospital. METHODS An electronic transfusion request form and a prospective audit of transfusion practice were implemented. After the one-year implementation period, a retrospective review was performed to assess transfusion practice in medical patients. RESULTS Pre-PBM, a total of 9478 RBC units were transfused (mean: 1.75 units per patient) compared with 9289 transfused units (mean: 1.57 units per patient) post-PBM. Regarding the post-PBM period, the mean hemoglobin (Hb) level of the 3099 medical patients without comorbidities transfused was 7.19 ± 0.79 gr/dL. Among them, 2065 (66.6%) had Hb levels >7.0 gr/dL, while 167 (5.3%) had Hb levels >8.0 gr/dL. In addition, 331 (25.3%) of the transfused patients with comorbidities had Hb >8.0 gr/dL. The Hb transfusion thresholds significantly differed across the clinics (p < 0.001), while 21.8% of all medical non-bleeding patients received more than one RBC unit transfusion. CONCLUSION A poor adherence with the restrictive transfusion threshold of 7.0 gr/dL was observed. The adoption of a less strict threshold might be a temporary step to allow physicians to become familiar with the program and be informed on the safety and advantages of the restrictive transfusion strategy.

Improved postoperative outcomes and reduced transfusion rates after implementation of a Patient Blood Management program in gastric cancer surgery. Eur J Surg Oncol 2020; 47:1449-1457. [PMID: 33267997 DOI: 10.1016/j.ejso.2020.11.129] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 11/06/2020] [Accepted: 11/20/2020] [Indexed: 02/06/2023] Open
Abstract
INTRODUCTION Gastric cancer patients are often transfused with red blood cells, with negative impact on postoperative course. This multicenter prospective interventional cohort study aimed to determine whether implementation of a Patient Blood Management (PBM) program, was associated with a decrease in transfusion rate and improvements in clinical outcomes in gastric cancer surgery. METHODS We compared transfusion practices and clinical outcomes in patients undergoing elective gastric cancer resection before and after implementing a PBM program, including strategies to detect and treat anemia and restrictive transfusion practice (2014-2018). Primary outcome was transfusion rate (TR). Secondary outcomes were complications, reoperations, length of stay, readmissions, 90-day mortality and failure-to-rescue. Differences were adjusted by confounding factors. RESULTS Some 789 patients were included (496 pre- and 293 post-PBM). TR decreased from 39.1% to 27.0% (adjusted difference -9.1, 95% CI -15.2 to -2.9), being reduction particularly significant in patients with anemia, ASA score 3-4, locally advanced tumors, undergoing open surgery and total gastrectomy. Infectious complications diminished from 25% to 16.4% (-6.1, 95%CI -11.5 to -0.7), reoperations from 8.1% to 6.1% (-2.2, 95%CI -5.1 to +0.6), median length of stay from 11 [IQR 8-18] to 8 [7-12] days (p < 0.001), hospital readmission from 14.1% to 8.9% (-5.4, 95%CI -9.6 to -1.1), mortality from 7.9% to 4.8% (-2.4, 95%CI -4.7 to -0.01), and failure-to rescue from 62.7% to 32.7% (-23.1, 95%CI -37.7 to -8.5). CONCLUSION Implementation of a PBM program was associated with a reduction in transfusion rate and improvement in postoperative outcomes in gastric cancer patients undergoing curative resection.

Abstract
The aim of this study was to evaluate the impact of using a thromboelastometry-based protocol on transfusion requirements in patients undergoing combined coronary artery bypass grafting (CABG) and valve surgery. 80 adult patients scheduled for elective combined CABG and valve surgery were included in this clinical trial study. Patients were randomly allocated to the thromboelastometry (ROTEM) (n = 40) or control groups (n = 40). In the ROTEM group, transfusion was directed according to a thromboelastometry-based protocol. In the control group, transfusion was conducted according to the routine practices including conventional coagulation testing and clinical judgments. Finally, transfusion requirements were compared between groups. Use of thromboelastometry- based protocol resulted in 67% reduction in blood products units' consumption as well as 23% in the percentage of patients transfused. This reduction was especially evident in relation to fresh frozen plasma (FFP) and platelet consumption. No significant differences were found both in the percentage of patients receiving RBC and number of transfused RBC units. Using thromboelastometry tests incorporated a protocol results in reduction of transfusion requirements in patients undergoing elective combined CABG and valve surgery.

Abstract
BACKGROUND This nationwide study aimed to investigate the blood transfusion status of elderly hip fracture patients and to examine the effect of packed red blood cell transfusion on all-cause mortality. METHODS From the Korean National Health Insurance Service-Senior cohort consisting of 588,147 participants aged over 60 years in 2002, a total of 14,744 new-onset hip fracture patients aged 65-99 years were followed up for 11 years. The adjusted hazard ratios (aHRs), risk ratios, and their 95% confidence intervals were estimated by the Cox proportional hazard model and Poisson regression model. RESULTS There were 10,973 patients (74.42%) in the transfusion group and 3,771 (25.58%) patients in the non-transfusion group. The mean volume of blood transfusion was 1,164.51 mL (± 865.25; median, 800 mL; interquartile range, 640-1,440). In the multivariable-adjusted Cox proportional hazard model, the transfusion group had 1.34-fold more risk of all-cause mortality than the non-transfusion group (aHR, 1.34; 95% confidence interval [CI], 1.26-1.42). In the multivariate-adjusted Poisson regression model, hip fracture patients in the transfusion group were 1.43 (adjusted risk ratio [aRR], 1.43; 95% CI, 1.09-1.87; P = 0.009) folds more likely to die within 30 days than those in the non-transfusion group. The mortality risk was highest at 90 days (aRR, 1.64; 95% CI, 1.40-1.93; P < 0.001) and slightly decreased at 180 days (aRR, 1.58; 95% CI, 1.40-1.79; P < 0.001) and 1 year (aRR, 1.43; 95% CI, 1.31-1.58; P < 0.001). CONCLUSION In this nationwide representative cohort study, blood transfusion was performed in 75% of hip fracture patients. Even after adjusting for comorbidity and anticoagulant use, the postoperative results (hospitalization, mortality) of the transfusion group did not show significantly worse results than the non-transfusion group. Therefore, adequate patient blood management can only improve the patient's outcome after hip fracture surgery.

Maturity Assessment model for Patient Blood Management to assist hospitals in improving patients' safety and outcomes. The MAPBM project. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2020; 19:205-215. [PMID: 32955422 DOI: 10.2450/2020.0105-20] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 04/19/2020] [Accepted: 05/26/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND Patient blood management (PBM) is an evidence-based care bundle with proven ability to improve patients' outcomes by managing and preserving the patient's own blood. Since 2010, the World Health Organisation has urged member states to implement PBM. However, there has been limited progress in developing PBM programmes in hospitals due to the implicit challenges of implementing them. To address these challenges, we developed a Maturity Assessment Model (MAPBM) to assist healthcare organisations to measure, benchmark, assess in PBM, and communicate the results of their PBM programmes. We describe the MAPBM model, its benchmarking programme, and the feasibility of implementing it nationwide in Spain. MATERIALS AND METHODS The MAPBM considers the three dimensions of a transformation effort (structure, process and outcomes) and grades these within a maturity scale matrix. Each dimension includes the various drivers of a PBM programme, and their corresponding measures and key performance indicators. The structure measures are qualitative, and obtained using a survey and structured self-assessment checklist. The key performance indicators for process and outcomes are quantitative, and based on clinical data from the hospitals' electronic medical records. Key performance indicators for process address major clinical recommendations in each PBM pillar, and are applied to six common procedures characterised by significant blood loss. RESULTS In its first 5 years, the MAPBM was deployed in 59 hospitals and used to analyse 181,826 hospital episodes, which proves the feasibility of implementing a sustainable model to measure and compare PBM clinical practice and outcomes across hospitals in Spain. CONCLUSION The MAPBM initiative aims to become a useful tool for healthcare organisations to implement PBM programmes and improve patients' safety and outcomes.

Abstract
PURPOSE Presently, Korea is facing new challenges associated with an imbalance in blood supply and demand. The purpose of this study was to examine trends in blood supply and demand in Korea over the past 10 years through 2018 and to propose what to prepare in the future. MATERIALS AND METHODS Age demographics in Korea were analyzed using data from the Statistics Korea. Blood donation and blood supply data were analyzed using Blood Services Statistics 2018 by the Korean Red Cross. Blood transfusion data from hospitals in 2018 were obtained from the Health Insurance Review and Assessment Service. RESULTS In 2018, 2883270 whole blood and apheresis units were collected in Korea. The Korean Red Cross supplied 4277762 blood components to 2491 hospitals. The overall blood donation rate was 5.6%, and the most frequent donors were young male donors. Leukoreduced red blood cells (RBCs) constituted 25% of all RBCs used, and 40% of all platelets were supplied by single-donor platelets. The self-sufficiency rate of domestic plasma with which to produce plasma-derived medicinal products was 68.7% in 2018. Blood use was the most frequent among patients aged 70-79 years. CONCLUSION Blood management in Korea is changing rapidly due to a low birth rate, rapid aging, and an increase in severely ill patients who require most of the blood supply. Therefore, future plans to promote donation at a national level and optimal use of blood in hospitals is necessary.

Abstract
Approximately 14-40% of patients in industrialized countries present with preoperative anemia. Depending on the severity, anemia is associates with increased perioperative morbidity and mortality. One of the most important causes of preoperative anemia is iron deficiency which is usually easy to treat. Implemented in the multimodal concept of patient blood management, the diagnostics and treatment of preoperative anemia are important aspects for improvement of perioperative outcome. Adequate and early diagnostics of the cause of anemia before treatment is important because treatment options, e.g. with iron, erythropoetin, folic acid and vitamin B12, may be expensive, may have severe side effects, and in the case of a wrong indication, will not improve anemia. In addition, an adequate regeneration of the erythrocyte volume requires time. This review article presents important aspects of the epidemiology and prognostic implications of preoperative anemia, the physiology and pathophysiology of anemia as well as diagnostic features and the evidence base for preoperative treatment options.

Abstract
Allogeneic blood transfusion is commonly prescribed to patients undergoing suprapubic prostatectomy for benign prostatic hyperplasia as a treatment option to replace blood loss. Historically, suprapubic prostatectomy has been perceived as an extremely high hemorrhagic surgery, and this has led to the association of suprapubic prostatectomy with a high rate of allogeneic blood transfusion. However, the outcome of suprapubic prostatectomy has significantly improved over the years and has become less hemorrhagic in many hands - creating the opportunity to consistently avoid allogeneic blood transfusion. On the other hand, the efficacy of blood transfusion has come under more stringent scrutiny as many clinical studies have reported inconsistent effects of blood transfusion on patient outcome. In contemporary practice, a more conservative/bloodless approach in the perioperative management of anemia in surgical patients is strongly being advocated with convincing evidence that many surgical patients can be routinely and safely managed without allogeneic blood transfusion. There is no large-scale discussion on bloodless surgery in urology in the contemporary literature, especially in the area of suprapubic prostatectomy that has been historically associated with a high rate of blood transfusion. This review article will discuss the evolution of bloodless surgery including the ongoing controversies surrounding blood transfusion in general, and then the relatively small but ongoing penetration of bloodless surgical approach in the field of suprapubic prostatectomy. Furthermore, the authors' approach to bloodless suprapubic prostatectomy will be highlighted, and in doing so, it can be emphasized that suprapubic prostatectomy is no more as hemorrhagic as was historically perceived, but rather a routine bloodless suprapubic prostatectomy is now possible in many hands.

Abstract
Objective Clinic of Anaesthesiology and Reanimation, Türkiye Yüksek İhtisas Training and Research Hospital, beginning in 2014, the patient blood management (PBM) protocol is individualised based on patients' comorbidities, and the threshold for transfusion is 7 g dL-1 of haemoglobin for patients without comorbidities and 8-9 g dL-1 for patients with comorbidities. In this study, our aim was to compare patient outcomes, requirement for transfusion and the cost of transfusion between two different periods with and without PBM protocol. Methods 229 and 283 patients who underwent open-heart surgery using cardiopulmonary bypass during the first 4 months of 2012 and the first 4 months of 2017, respectively, were included in this retrospective, cross-sectional study. Results There were no differences between the groups in preoperative data. Blood and blood product usage was observed to be significantly lower at the time of the PBM protocol. The use of packed red blood cells decreased from 2 units to 0and that of fresh frozen plasma decreased from 2 units to 0. In terms of postoperative mortality, there were no differences between the groups. Conclusion According to the results of this study, the transfusion of unnecessary blood and blood products was reduced and the cost decreased with PBM protocol. Blood product usage did not affect 30-day mortality. It will be possible to achieve more valuable results if more patients are assessed, PBM protocol is implemented and postoperative results are evaluated in detail.

Abstract
BACKGROUND Clinicians are tasked with monitoring surgical blood loss. Unfortunately, there is no reliable method available to assure an accurate result. Most blood lost during surgery ends up on surgical sponges and within suction canisters. A novel Food and Drug Administration-cleared device (Triton system; Gauss Surgical, Inc, Los Altos, CA) to measure the amount of blood present on sponges using computer image analysis has been previously described. This study reports on performance of a complementary Food and Drug Administration-cleared device (Triton Canister System; Gauss Surgical, Inc, Los Altos, CA) that uses similar image analysis to measure the amount of blood in suction canisters. METHODS Known quantities of expired donated whole blood, packed red blood cells, and plasma, in conjunction with various amounts of normal saline, were used to create 207 samples representing a wide range of blood dilutions commonly seen in suction canisters. Each sample was measured by the Triton device under 3 operating room lighting conditions (bright, medium, and dark) meant to represent a reasonable range, resulting in a total of 621 measurements. Using the Bland-Altman method, the measured hemoglobin (Hb) mass in each sample was compared to the results obtained using a standard laboratory assay as a reference value. The analysis was performed separately for samples measured under each lighting condition. It was expected that under each separate lighting condition, the device would measure the various samples within a prespecified clinically significant Hb mass range (±30 g per canister). RESULTS The limits of agreement (LOA) between the device and the reference method for dark (bias: 4.7 g [95% confidence interval {CI}, 3.8-5.6 g]; LOA: -8.1 g [95% CI, -9.7 to -6.6 g] to 17.6 g [95% CI, 16.0-19.1 g]), medium (bias: 3.4 g [95% CI, 2.6-4.1 g]; LOA: -7.4 g [95% CI, -8.7 to -6.1 g] to 14.2 g [95% CI, 12.9-15.5 g]), and bright lighting conditions (bias: 4.1 g [95% CI, 3.2-4.9 g]; LOA: -7.6 g [95% CI, -9.0 to -6.2 g] to 15.7 g [95% CI, 14.3-17.1 g]) fell well within the predetermined clinically significant limits of ±30 g. Repeated measurements of the samples under the various lighting conditions were highly correlated with intraclass correlation coefficient of 0.995 (95% CI, 0.993-0.996; P < .001), showing that lighting conditions did not have a significant impact on measurements. Hb mass bias was significantly associated with hemolysis level (Spearman ρ correlation coefficient, -0.137; P = .001) and total canister volume (Spearman ρ correlation coefficient, 0.135; P = .001), but not ambient illuminance. CONCLUSIONS The Triton Canister System was able to measure the Hb mass reliably with clinically acceptable accuracy in reconstituted blood samples representing a wide range of Hb concentrations, dilutions, hemolysis, and ambient lighting settings.

Abstract
BACKGROUND Administration of blood products may be associated with increased morbidity and perioperative mortality in surgical patients. METHODS Patients aged 18 + who underwent gastrointestinal surgery at the Ohio State University Wexner Medical Center 9/10/2015-5/9/2018 were identified. Multivariable logistic regression models were used to evaluate impact of blood product use on survival and complications, as well as to identify factors associated with receipt of transfusions. RESULTS Among 10,756 patients, 35,517 units of blood products were transfused. Preoperative nadir hemoglobin was associated with receipt of blood product transfusion (OR 0.55, 95% CI 0.53, 0.68). After adjusting for patient and procedural characteristics, patients undergoing transfusion of blood products had an increased risk of perioperative mortality (OR 7.80, 95% CI 6.02, 10.10). CONCLUSIONS The use of blood products was associated with increased risk of complication and death. Patient blood management programs should be implemented to provide rational criteria and guidance for the transfusion of blood products.

Abstract
INTRODUCTION Patientblood management (PBM) is defined as the application of evidence-based diagnostic, preventive and therapeutic approaches designed to maintain haemoglobin concentration, optimise haemostasis and minimise blood loss in an effort to improve patient outcome. We propose a protocol for the assessment of the evidence of diagnostic, preventive and therapeutic approaches for the management of relevant outcomes in obstetrics with the aim to create a framework for PBM implementation. METHODS AND ANALYSIS Diagnostic, preventive and therapeutic tools will be considered in the gynaecological conditions and obstetrics setting (antenatal care, peripartum care and maternity care). For each condition, (1) clinical questions based on prioritised outcomes will be developed; (2) evidence will be retrieved systematically from electronic medical literature (MEDLINE, EMBASE, the Cochrane Library, Web of Science, and CINAHL); (3) quality of the reviews will be assessed using the AMSTAR (A Measurement Tool to Assess Systematic Reviews) checklist; quality of primary intervention studies will be assessed using the risk of bias tool (Cochrane method); quality of diagnostic primary studies will be assessed using QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies); (4) the Grading of Recommendations Assessment, Development and Evaluation method will be applied to rate the quality of the evidence and to develop recommendations. ETHICS AND DISSEMINATION For each diagnostic, preventive or therapeutic intervention evaluated, a manuscript comprising the evidence retrieved and the recommendation produced will be provided and published in peer-reviewed journals. Ethical approval is not required.

Voorn VMA, van Bodegom-Vos L, So-Osman C. Towards a systematic approach for (de)implementation of patient blood management strategies. Transfus Med 2018; 28:158-167.

Abstract
Despite the increasing availability of evidence in transfusion medicine literature, this evidence does not automatically find its way into practice. This is also applicable to patient blood management (PBM). It may concern the lack of implementation of effective new techniques or treatments, or it may apply to the (over)use of techniques and treatments (e.g. inappropriate transfusions) that have proven to be of limited benefit for patients (low-value care) and could be abandoned (de-implementation). In PBM literature, the implementation of restrictive transfusion thresholds and the de-implementation of inappropriate transfusions are described. However, most implementation strategies were not preceded by the identification of relevant barriers, and the used strategies were not often supported by literature on behavioural changes. In this article, we describe implementation vs de-implementation, highlight the current situation of (de)implementation in PBM and describe a systematic approach for (de)implementation illustrated by an example of a PBM de-implementation study regarding '(cost-) effective patient blood management in total hip and knee arthroplasty'. The systematic approach used for (de)implementation is based on the implementation model of Grol, which consists of the following five steps: the detection of improvement goals, a problem analysis, the selection of (de)implementation strategies, the execution of the (de)implementation strategy and an evaluation. Based on the description of the current situation and the experiences in our de-implementation study, we can conclude that de-implementation may be more difficult than expected as other factors may play a role in effective de-implementation compared to implementation.

Abstract
The objective of this article is to determine the availability of a perioperative transfusion management program (Patient Blood Management [PBM]) in various hospitals through a survey that included a description of the preanesthesia visit, the availability and use of the various blood-sparing techniques and the factors limiting their implementation in elective surgery. The survey included 42 questions, directed at the representative departments of anesthesiology of hospitals in Spain (n=91). The survey was conducted from September to November 2012. We analyzed the 82 surveys in which all the questions were answered (90%). Preoperative consultations are routinely performed (>70%) in 87% of the hospitals. The time from the consultation to surgery varied between 1 week and 2 months for 74% of the patients scheduled for orthopedic or trauma surgery, 78% of those scheduled for oncologic surgery and 77% of those scheduled for cardiac surgery. Almost all hospitals (77, 94%) had a transfusion committee, and 90% of them had an anesthesiologist on the committee. Seventy-nine percent of the hospitals had a blood-sparing program, and the most widely used technique was the use of antifibrinolytic agents (75% of hospitals), followed by intraoperative and postoperative blood recovery in equal proportions (67%). Optimization of preoperative hemoglobin was routinely performed with intravenous iron in 39% of the hospitals and with recombinant erythropoietin in 28% of the hospitals. The absence of a well-established circuit and the lack of involvement and collaboration with the surgical team were the main limiting factors in implementing PBM. Currently, the implementation of PBM in Spain could be considered acceptable, but it could also be improved, especially in the treatment of preoperative anemia. The implementation of PBM requires multidisciplinary collaboration among all personnel responsible for perioperative care, including the health authorities.

Abstract
Anemia is a common and often ignored condition in surgical patients. Anemia is usually multifactorial and iron deficiency and inflammation are commonly involved. An exacerbating factor in surgical patients is iatrogenic blood loss. Anemia has been repeatedly shown to be an independent predictor of worse outcomes. Patient blood management (PBM) provides a multimodality framework for prevention and management of anemia and related risk factors. The key strategies in PBM include support of hematopoiesis and improving hemoglobin level, optimizing coagulation and hemostasis, use of interdisciplinary blood conservation modalities, and patient-centered decision making throughout the course of care.

Abstract
OBJECTIVES A post hoc gender comparison of transfusion-related modifiable risk factors among patients undergoing elective surgery. SETTINGS 23 Austrian centres randomly selected and stratified by region and level of care. PARTICIPANTS We consecutively enrolled in total 6530 patients (3465 women and 3065 men); 1491 underwent coronary artery bypass graft (CABG) surgery, 2570 primary unilateral total hip replacement (THR) and 2469 primary unilateral total knee replacement (TKR). MAIN OUTCOME MEASURES Primary outcome measures were the number of allogeneic and autologous red blood cell (RBC) units transfused (postoperative day 5 included) and differences in intraoperative and postoperative transfusion rate between men and women. Secondary outcomes included perioperative blood loss in transfused and non-transfused patients, volume of RBCs transfused, perioperative haemoglobin values and circulating red blood volume on postoperative day 5. RESULTS In all surgical groups, the transfusion rate was significantly higher in women than in men (CABG 81 vs 49%, THR 46 vs 24% and TKR 37 vs 23%). In transfused patients, the absolute blood loss was higher among men in all surgical categories while the relative blood loss was higher among women in the CABG group (52.8 vs 47.8%) but comparable in orthopaedic surgery. The relative RBC volume transfused was significantly higher among women in all categories (CABG 40.0 vs 22.3; TKR 25.2 vs 20.2; THR 26.4 vs 20.8%). On postoperative day 5, the relative haemoglobin values and the relative circulating RBC volume were higher in women in all surgical categories. CONCLUSIONS The higher transfusion rate and volume in women when compared with men in elective surgery can be explained by clinicians applying the same absolute transfusion thresholds irrespective of a patient's gender. This, together with the common use of a liberal transfusion strategy, leads to further overtransfusion in women.

Abstract
Norway has recently established a working group to implement a national patient blood management (PBM) program. Although benchmarking regarding blood usage is challenging in Norway due to legal barriers, a survey was sent to different hospitals to identify possible areas to be prioritized in the first phase of the PBM program. Among them, optimizing the patient's hemoglobin level before elective surgery and implementing electronic check-lists for the indication of transfusion when ordering blood products are two measures that may have a considerable impact on blood usage. The results of the survey also showed that patients may receive a red blood cell transfusion at hemoglobin levels that are higher than those internationally recommended. Since there are no national guidelines for the use of blood products, agreement regarding hemoglobin thresholds is essential to reduce variation in transfusion practice. To achieve these goals, the transfusion specialist plays a key role in promoting the principles behind the PBM concept at the local hospital.

Abstract
Transfusion-transmitted infections remain among the most-feared complications of allogeneic blood transfusion. Thanks to several strategies including donor screening and deferral, blood testing and pathogen inactivation, their risks have reached all-time low levels, particularly in developed nations. Nonetheless, new and emerging infections remain a threat that is likely to exacerbate in the coming years with continued globalization and climate change. More effective strategies of pathogen inactivation and more vigilant horizon screening are hoped to abate the risk. Additionally, allogeneic transfusion has repeatedly been shown to be associated with worsening of outcomes in patients, including the documented increased risk of infections (often nosocomial) in recipients of transfusions. The underlying mechanism is likely to be related to immunosuppressive effects of allogeneic blood, iron content, and bacterial contamination. This issue is best addressed by more judicious and evidence-based use of allogeneic blood components to ensure the potential benefits outweigh the risks.

Abstract
PURPOSE OF REVIEW Infusion therapy is essential in intravascular hypovolaemia and extravascular fluid deficits. Crystalloidal fluids and colloidal volume replacement affect blood coagulation when infused intravenously. The question remains if this side-effect of infusion therapy is clinically relevant in patients with and without bleeding manifestations, and if fluid-induced coagulopathy is a risk factor for anaemia, blood transfusion, and mortality, and a driver for resource use and costs. RECENT FINDINGS Pathomechanisms of dilutional coagulopathy and evidence for its clinical relevance in perioperative and critically ill patients are reviewed. Furthermore, the article discusses medicolegal aspects. SUMMARY The dose-dependent risk of dilutional coagulopathy differs between colloids (dextran > hetastarch > pentastarch > tetrastarch, gelatins > albumin). Risk awareness includes monitoring for early signs of side-effects. With rotational thromboelastometry/thrombelastography, the deterioration not only in clot strength but also in clot formation and in platelet interaction can be assessed. Fibrinogen concentrate administration may be considered in severe bleeding as well as relevant dilutional coagulopathy. Targeted doses of gelatins and tetrastarches seem to have no proven adverse effect on anaemia and allogeneic blood transfusions. Further studies are needed.

Abstract
BACKGROUND Orthopedic surgery, especially spine and spinal deformity surgery, may be associated with high perioperative blood loss. In order to reduce the risk of excessive blood loss and unnecessary blood transfusions, strategies such as Patient Blood Management including goal-directed coagulation management have been developed. RECENT FINDINGS Adverse effects of allogeneic blood transfusions have been shown for most surgical fields including orthopedic surgery. Several efforts have been made to increase the preoperative red blood cell (RBC) mass, to reduce the intraoperative blood loss, and to use restrictive transfusion triggers in order to minimize or avoid RBC transfusions. Measures to reduce intraoperative blood loss include new surgical techniques, use of cell salvage where possible, bedside coagulation management with point-of-care devices, substitution of coagulation factors, antifibrinolytic agents, and desmopressin, induced hypotension, and avoidance of hypothermia. SUMMARY Blood conservation in spinal surgery is a multidisciplinary approach and the efficacy of most single measures has been shown. Cost-effectiveness and the benefits of long-term patient outcomes are the subjects of current and future research.

Abstract
Patient Blood Management (PBM) is the design of a personalized, multimodal multidisciplinary plan for minimizing transfusion and simultaneously achieving a positive impact on patient outcomes. The first pillar of PBM consists of optimizing the erythrocyte mass. The best chance for this step is offered by preoperative preparation. In most cases, a detailed medical history, physical examination and laboratory tests will identify the cause of anemia. A correct evaluation of parameters that assess the state and function of iron, such as ferritin levels, and the parameters that measure functional iron, such as transferrin saturation and soluble transferrin receptor levels, provide us with essential information for guiding the treatment with iron. The new blood count analyzers that measure hypochromia (% of hypochromic red blood cells and reticulocyte hemoglobin concentrations) provide us useful information for the diagnosis and follow-up of the response to iron treatment. Measuring serum folic acid and vitamin B12 levels is essential for treating deficiencies and thereby achieving better hemoglobin optimization.

Abstract
BACKGROUND AND OBJECTIVES Excessive bleeding is a risk associated with cardiac surgery. Treatment invariably requires transfusion of blood products; however, the transfusion itself may contribute to postoperative sequelae. Our objective was to analyse a quality initiative designed to provide an evidenced-based approach to bleeding management. MATERIALS AND METHODS A retrospective analysis compared blood product transfusion and patient outcomes 15 months before and after implementation of a bleeding management protocol. The protocol incorporated point-of-care coagulation testing (POCCT) with ROTEM and Multiplate to diagnose the cause of bleeding and monitor treatment. RESULTS Use of the protocol led to decreases in the incidence of transfusion of PRBCs (47·3% vs. 32·4%; P < 0·0001), FFP (26·9% vs. 7·3%; P < 0·0001) and platelets (36·1% vs. 13·5%; P < 0·0001). During the intra-operative period, the percentage of patients receiving cryoprecipitate increased (2·7% vs. 5·1%; P = 0·002), as did the number of units transfused (248 vs. 692; P < 0·0001). The proportion of patients who received tranexamic acid increased (13·7% to 68·2%; P < 0·0001). There were reductions in re-exploration for bleeding (5·6% vs. 3·4; P = 0·01), superficial chest wound (3·3% vs. 1·4%; P = 0·002), leg wound infection (4·6% vs. 2·0%; P < 0·0001) and a 12% reduction in mean length of stay from operation to discharge (95%: 9-16%, P < 0·0001). Acquisition cost of blood products decreased by $1 029 118 in the 15-month period with the protocol. CONCLUSIONS The implementation of a bleeding management protocol supported by POCCT in a cardiac surgery programme was associated with significant reductions in the transfusion of allogeneic blood products, improved outcomes and reduced cost.

Abstract
PURPOSE OF REVIEW Bleeding can be minimal, severe, life-threatening, or organ-threatening. Depending on the compensatory capacity of the patient, most bleeding events going beyond 20% blood volume may represent an emergency as well as a risk factor for anemia, transfusion, coagulopathy, and tissue hypoperfusion. All these factors are independent predictors for survival in postoperative critical care and are drivers for resource use and costs. RECENT FINDINGS A systematic literature search behind the guidelines from the European Society of Anesthesiology on the management of severe perioperative bleeding gives an up-to-date evidence-based summary of strategies intended to correct hemostasis, control bleeding, and increase patient safety. The current review discusses information, recommendations, and suggestions in the European Society of Anesthesiology guidelines, which appear applicable to the bleeding patient after the end of surgery. SUMMARY Individualized coagulation management guided by viscoelastic tests and restrictive transfusion behavior are encouraged in clinical practice of critical care. Potential fields of research are multifold, for example, thromboembolic adverse effects of hemostatic interventions in the isochronic postoperative acute-phase response, transfusion restrictions by increasing postoperative tolerance to anemia and erythropoiesis, and implementation of guidelines and institutional algorithms.

Abstract
In the last years it has become evident that the use of blood products should be reduced whenever possible. There is increasing evidence regarding serious adverse events, including higher mortality and morbidity, related to transfusions. The use of point of care (POC) devices integrated in algorithms is one of the important mechanisms to limit blood product exposure. Any type of algorithm, especially the POC-based ones, allows goal-directed transfusions of blood products and even better targeted factor concentrate substitutions. Different types of algorithms in different surgical settings (cardiac surgery, trauma, liver surgery etc.) have been established with growing interest in their use as they offer objective therapy for management and reduction of blood product use. The use of POC devices with evidence-based algorithms is important in the bleeding patient independent of its origin (traumatic vs. surgical). The use of factor concentrates compared to the classical blood products can be cost-saving, beneficial for the patient, and in agreement with the WHO-requested standard of care. The empiric and uncontrolled use of blood products such as fresh frozen plasma, red blood cells, and platelets without POC monitoring should no longer be followed with regard to actual evidence in literature. Furthermore, the use of factor concentrates may provide better outcomes and potential for cost saving.

Patient blood management in orthopaedic surgery: a four-year follow-up of transfusion requirements and blood loss from 2008 to 2011 at the Balgrist University Hospital in Zurich, Switzerland. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2015; 12:195-203. [PMID: 24931841 DOI: 10.2450/2014.0306-13] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 11/07/2013] [Accepted: 02/10/2014] [Indexed: 01/05/2023]
Abstract
BACKGROUND The aim of this study was to investigate the impact of the introduction of a Patient Blood Management (PBM) programme in elective orthopaedic surgery on immediate pre-operative anaemia, red blood cell (RBC) mass loss, and transfusion. MATERIALS AND METHODS Orthopaedic operations (hip, n=3,062; knee, n=2,953; and spine, n=2,856) performed between 2008 and 2011 were analysed. Period 1 (2008), was before the introduction of the PBM programme and period 2 (2009 to 2011) the time after its introduction. Immediate pre-operative anaemia, RBC mass loss, and transfusion rates in the two periods were compared. RESULTS In hip surgery, the percentage of patients with immediate pre-operative anaemia decreased from 17.6% to 12.9% (p<0.001) and RBC mass loss was unchanged, being 626±434 vs 635±450 mL (p=0.974). Transfusion rate was significantly reduced from 21.8% to 15.7% (p<0.001). The number of RBC units transfused remained unchanged (p=0.761). In knee surgery the prevalence of immediate pre-operative anaemia decreased from 15.5% to 7.8% (p<0.001) and RBC mass loss reduced from 573±355 to 476±365 mL (p<0.001). The transfusion rate dropped from 19.3% to 4.9% (p<0.001). RBC transfusions decreased from 0.53±1.27 to 0.16±0.90 units (p<0.001). In spine surgery the prevalence of immediate pre-operative anaemia remained unchanged (p=0.113), RBC mass loss dropped from 551±421 to 404±337 mL (p<0.001), the transfusion rate was reduced from 18.6 to 8.6% (p<0.001) and RBC transfusions decreased from 0.66±1.80 to 0.22±0.89 units (p=0.008). DISCUSSION Detection and treatment of pre-operative anaemia, meticulous surgical technique, optimal surgical blood-saving techniques, and standardised transfusion triggers in the context of PBM programme resulted in a lower incidence of immediate pre-operative anaemia, reduction in RBC mass loss, and a lower transfusion rate.
