Usefulness of the d-dimer to albumin ratio for risk assessment in patients with acute variceal bleeding at the emergency department: retrospective observational study. BMC Emerg Med 2022; 22:135. [PMID: 35879671 PMCID: PMC9311345 DOI: 10.1186/s12873-022-00696-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Accepted: 07/20/2022] [Indexed: 11/29/2022] Open
Abstract
Background Acute variceal bleeding (AVB) is a severe complication of portal hypertension that is caused by rupture of the esophageal or gastric varix. Scoring system for risk stratification of AVB is difficult to use because various variables must be entered, and it is difficult to apply early in the emergency department (ED). We compared and analyzed the usefulness of the D-dimer to albumin ratio (DAR) for risk stratification of AVB. Methods In this retrospective observational study, medical records of patients with AVB Between January 2019 and December 2020 were assessed. The primary endpoint was to evaluate whether DAR was a predictor of clinical outcomes for AVB. Receiver operating characteristic (ROC) curves were constructed using cut-off values determined by the Youden Index. Univariate and multivariate logistic regression analyses were performed to assess the factors contributing to the development of outcomes. Results Overall, 67 patients required intensive care. The cut-off value of DAR for patients requiring intensive care was 400. A DAR > 400 (adjusted HR: 5.636 [95% CI: 2.216–14.332]) independently predicted the need for ICU admission in these patients. Overall, 13 patients required long-term hospitalization. The cut-off value of DAR for patients requiring long-term hospitalization was 403. A DAR > 403 (adjusted HR: 9.899 [95% CI: 2.012–48.694]) independently predicted the need for long-term hospitalization. Overall, 95 patients required transfusion. The cut-off value of DAR for patients requiring transfusion was 121. A DAR > 121 (adjusted HR: 4.680 [95% CI: 1.703–12.862]) independently predicted the need for transfusion. Overall, 11 patients died during study period. The cut-off value of DAR for mortality was 450. A DAR > 450 (adjusted HR: 26.261 [95% CI: 3.054–225.827]) independently predicted mortality. Conclusions The DAR can be used for outcome assessment in patients with AVB with various scoring systems, but its explanatory power is not high.

Transfusion Guidelines in Brain Tumor Surgery: A Systematic Review and Critical Summary of Currently Available Evidence. World Neurosurg 2022; 165:172-179.e2. [PMID: 35752421 DOI: 10.1016/j.wneu.2022.06.077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 06/14/2022] [Accepted: 06/15/2022] [Indexed: 01/28/2023]
Abstract
OBJECTIVE Red blood cell (RBC) transfusion is commonly indicated in brain tumor surgery due to risk of blood loss. Current transfusion guidelines are based on evidence derived from critically ill patients and may not be optimal for brain tumor surgeries. Our study is the first to synthesize available evidence to suggest RBC transfusion thresholds in brain tumor patients undergoing surgery. METHODS A systematic review was conducted using PubMed, EMBASE, and Google Scholar databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines to critically assess RBC transfusion thresholds in adult patients with brain tumors and complications secondary to transfusion following blood loss in the operating room (OR) or the perioperative period. RESULTS Seven (7) articles meeting our search criteria were reviewed. Brain tumor patients who received blood transfusions were older, had greater rates of ASA class 3 or 4, and presented with increased number of comorbidities including diabetes, hypertension, and cardiovascular diseases. In addition, transfused patients had a prolonged surgical time. Transfusions were associated with multiple postoperative major and minor complications, including longer hospital length of stay (LOS), increased return to the OR, and elevated 30-day mortality. Analysis of transfusion thresholds showed that a restrictive hemoglobin (Hb) threshold of 8 g/dL is safe in patients, as evidenced by a reduction in LOS, mortality, and complications (Level C Class IIa). CONCLUSIONS A restrictive Hb threshold of 8 g/dL appears to be safe and minimizes potential complications of transfusion in brain tumor patients. LEVEL OF EVIDENCE Class C Level IIa.

Abstract
Background Red blood cells (RBCs) are an essential factor to consider for modern medicine, but planning the future collection of RBCs and supply efforts for coping with fluctuating demands is still a major challenge. Objectives This study aimed to explore the feasibility of the time-series model in predicting the clinical demand of RBCs for pediatric patients each month. Methods Our study collected clinical RBC transfusion data from years 2014 to 2019 in the National Center for Children's Health (Beijing) in China, with the goal of constructing a time-series, autoregressive integrated moving average (ARIMA) model by fitting the monthly usage of RBCs from 2014 to 2018. Furthermore, the optimal model was used to forecast the monthly usage of RBCs in 2019, and we subsequently compared the data with actual values to verify the validity of the model. Results The seasonal multiplicative model SARIMA (0, 1, 1) (1, 1, 0)12 (normalized BIC = 8.740, R2 = 0.730) was the best prediction model and could better fit and predict the monthly usage of RBCs for pediatric patients in this medical center in 2019. The model residual sequence was white noise (Ljung-Box Q(18) = 15.127, P > 0.05), and its autocorrelation function (ACF) and partial autocorrelation function (PACF) coefficients also fell within the 95% confidence intervals (CIs). The parameter test results were statistically significant (P < 0.05). 91.67% of the actual values were within the 95% CIs of the forecasted values of the model, and the average relative error of the forecasted and actual values was 6.44%, within 10%. Conclusions The SARIMA model can simulate the changing trend in monthly usage of RBCs of pediatric patients in a time-series aspect, which represents a short-term prediction model with high accuracy. The continuously revised SARIMA model may better serve the clinical environments and aid with planning for RBC demand. A clinical study including more data on blood use should be conducted in the future to confirm these results.

Blood Transfusion Predicts Prolonged Mechanical Ventilation in Acute Stanford Type A Aortic Dissection Undergoing Total Aortic Arch Replacement. Front Cardiovasc Med 2022; 9:832396. [PMID: 35498041 PMCID: PMC9053570 DOI: 10.3389/fcvm.2022.832396] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Accepted: 03/15/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundThis research aimed to evaluate the impacts of transfusing packed red blood cells (pRBCs), fresh frozen plasma (FFP), or platelet concentrate (PC) on postoperative mechanical ventilation time (MVT) in patients with acute Stanford type A aortic dissection (ATAAD) undergoing after total arch replacement (TAR).MethodsThe clinical data of 384 patients with ATAAD after TAR were retrospectively collected from December 2015 to October 2017 to verify whether pRBCs, FFP, or PC transfusion volumes were associated with postoperative MVT. The logistic regression was used to assess whether blood products were risk factors for prolonged mechanical ventilation (PMV) in all three endpoints (PMV ≥24 h, ≥48 h, and ≥72 h).ResultsThe mean age of 384 patients was 47.6 ± 10.689 years, and 301 (78.39%) patients were men. Median MVT was 29.5 (4–574) h (h), and 213 (55.47%), 136 (35.42%), and 96 (25.00%) patients had PMV ≥24 h, ≥48 h, and ≥72 h, respectively. A total of 36 (9.38%) patients did not have any blood product transfusion, the number of patients with transfusion of pRBCs, FFP, and PC were 334 (86.98%), 286 (74.48%), and 189 (49.22%), respectively. According to the multivariate logistic regression of three PMV time-endpoints, age was a risk factor [PMV ≥ 24 h odds ratio (ORPMV≥24) = 1.045, p = 0.005; ORPMV≥48 = 1.060, p = 0.002; ORPMV≥72 = 1.051, p = 0.011]. pRBC transfusion (ORPMV≥24 = 1.156, p = 0.001; ORPMV≥48 = 1.156, p < 0.001; ORPMV≥72 = 1.135, p ≤ 0.001) and PC transfusion (ORPMV≥24 = 1.366, p = 0.029; ORPMV≥48 = 1.226, p = 0.030; ORPMV≥72 = 1.229, p = 0.011) were independent risk factors for PMV. FFP had no noticeable effect on PMV [ORPMV≥48 = 0.999, 95% confidence interval (CI) 0.998–1.000, p = 0.039; ORPMV≥72 = 0.999, 95% CI: 0.998–1.000, p = 0.025].ConclusionsIn patients with ATAAD after TAR, the incidence of PMV was very high. Blood products transfusion was closely related to postoperative mechanical ventilation time. pRBC and PC transfusions and age increased the incidence of PMV at all three endpoints.

Lack of alloimmunization to the D antigen in D-negative orthotopic liver transplant recipients receiving D-positive red blood cells perioperatively. Vox Sang 2022; 117:1043-1047. [PMID: 35393659 DOI: 10.1111/vox.13282] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Revised: 03/09/2022] [Accepted: 03/27/2022] [Indexed: 01/28/2023]
Abstract
BACKGROUND AND OBJECTIVES D-negative patients undergoing orthotopic liver transplantation (OLT) might require a large number of red blood cell (RBC) units, which can impact the inventory of D-negative blood. The blood bank might need to supply these patients with D-positive RBCs because of inventory constraints. This study evaluates the prevalence of anti-D formation in D-negative OLT patients who received D-positive RBCs perioperatively, as this will assist in successful patient blood management. MATERIALS AND METHODS This was a retrospective study performed at a single academic medical centre. Electronic medical records for all 1052 consecutive patients who underwent OLT from January 2007 through December 2017 were reviewed. D-negative patients who were transfused perioperatively with D-positive RBCs and had antibody screening at least 30 days after transfusion were included. RESULTS Of a total of 155 D-negative patients, 23 (14.8%) received D-positive RBCs perioperatively. Seventeen patients were included in the study. The median age was 54 years (range 36-67 years); 13 (76.5%) were male. The median number of D-positive RBC units transfused perioperatively was 7 (range 1-66 units). There was no evidence of D alloimmunization in any patient after a median serologic follow-up of 49.5 months (range 31 days to 127.7 months). The average number of antibody screening post OLT was 7.29. CONCLUSION Our study showed that transfusion of D-positive RBCs in D-negative OLT recipients is a safe and acceptable practice in the setting of immunosuppression. This practice allows the conservation of D-negative RBC inventory.

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
Human red blood cells (RBCs) are approximately 8 μm in diameter, but must repeatedly deform through capillaries as small as 2 μm in order to deliver oxygen to all parts of the body. The loss of this capability is associated with the pathology of many diseases, and is therefore a potential biomarker for disease status and treatment efficacy. Measuring RBC deformability is a difficult problem because of the minute forces (∼pN) that must be exerted on these cells, as well as the requirements for throughput and multiplexing. The development of technologies for measuring RBC deformability date back to the 1960s with the development of micropipette aspiration, ektacytometry, and the cell transit analyzer. In the past 10 years, significant progress has been made using microfluidics by leveraging the ability to precisely control fluid flow through microstructures at the size scale of individual RBCs. These technologies have now surpassed traditional methods in terms of sensitivity, throughput, consistency, and ease of use. As a result, these efforts are beginning to move beyond feasibility studies and into applications to enable biomedical discoveries. In this review, we provide an overview of both traditional and microfluidic techniques for measuring RBC deformability. We discuss the capabilities of each technique and compare their sensitivity, throughput, and robustness in measuring bulk and single-cell RBC deformability. Finally, we discuss how these tools could be used to measure changes in RBC deformability in the context of various applications including pathologies caused by malaria and hemoglobinopathies, as well as degradation during storage in blood bags prior to blood transfusions.

Abstract
BACKGROUND The impact of packed Red Blood Cell (pRBC) transfusion on oncological outcomes after liver transplantation (LT) for Hepatocellular Carcinoma (HCC) remains controversial. We evaluated the impact of pRBC transfusion on HCC recurrence and overall survival (OS) after LT for HCC. METHODS Patients with HCC transplanted between 2000 and 2018 were included and stratified by receipt of pRBC transfusion. Outcomes were HCC recurrence and OS. Propensity score matching was performed to account for confounders. RESULTS Of the 795 patients, 234 (29.4%) did not receive pRBC transfusion. After matching the 1-, 3-, and 5-year cumulative incidence of recurrence was 6.6%, 12.5% and 14.8% for no-pRBC transfusion, and 8.6%, 18.8% and 21.3% (p = 0.61) for pRBC transfusion. The OS at 1-, 3-, 5-year was 93.0%, 84.6% and 75.8% vs 92.0%, 79.7% and 73.5% (p = 0.83) for no-pRBC transfusion and pRBC transfusion, respectively. There were no differences in recurrence (HR 1.13, 95%CI 0.71-1.78, p = 0.61) or OS (HR 1.04, 95%CI 0.71-1.54, p = 0.83). CONCLUSION Perioperative administration of pRBC in liver transplant recipients for HCC resulted in a nonsignificant increase of HCC recurrence and death after accounting for confounder. Surgeons should continue to exercise cation and optimize patients iron stores medically preoperatively.

J Clin Med 2022; 11:jcm11041037. [PMID: 35207310 PMCID: PMC8879325 DOI: 10.3390/jcm11041037] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 02/05/2022] [Accepted: 02/16/2022] [Indexed: 02/04/2023] Open
Abstract
Anemia should preferably be managed without red blood cell transfusion (RBCT); instead, therapy should be focused on causes of anemia along with efforts to minimize blood loss. Lactate could potentially be used as a physiologic RBCT trigger, although there are some limitations to its interpretation. The aim of our study was to analyze the impact of RBCT on blood lactate with consideration of factors known to increase its concentration and to assess the usefulness of blood lactate as a potential physiologic RBCT trigger. We performed a retrospective analysis of all RBCT episodes in non-bleeding critically ill patients. We retrieved demographic data, data on RBCT itself (duration, type of RBC, volume of RBC, age of RBC), laboratory parameters (lactate, hemoglobin, glucose, total bilirubin), and factors potentially increasing lactate. We analyzed 77 RBCTs with elevated pre-RBCT lactate. The median age of patients was 66 (IQR 57–73) years and the distribution of sexes was even. The named factors potentially influencing lactate had no impact on its concentration. The median pre-post RBCT lactate was 2.44 (IQR 2.08–3.27) and 2.13 (IQR 1.75–2.88) mmol/L, respectively (p < 0.01); the median decrease was 0.41 (IQR 0.07–0.92) mmol/L. We conclude that RBCT did not normalize mildly elevated lactate. Common causes of elevated lactate probably had no impact on its concentration. Therefore lactate may have a limited role as a physiologic RBCT trigger in non-bleeding severely anemic critically ill patients.

J Orthop Surg Res 2022; 17:85. [PMID: 35148802 PMCID: PMC8832772 DOI: 10.1186/s13018-022-02955-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 01/21/2022] [Indexed: 02/08/2023] Open
Abstract
Introduction Given the possibility of inadvertent bacterial contamination of salvaged blood, the use of cell salvage is relatively contraindicated in cases of reimplantation for chronic hip periprosthetic joint infection (PJI). However, there are no published data supporting this assertion. The purpose of the current study was to compare the reinfection rate and rate of postoperative allogeneic blood transfusion (ABT) in second-stage reimplantation for PJI with or without intraoperative cell salvage reinfusion. Materials and methods We identified 125 patients who underwent two-stage exchange for chronic hip PJI between November 2012 and April 2019. The groups of patients who had (n = 61) and had not (n = 64) received intraoperative cell salvage reinfusion were compared with respect to the curative infection-free rate. Moreover, we compared the need for postoperative ABT and identified independent factors associated with ABT using multiple regression analysis. Results The log-rank survival curve with an endpoint of infection eradication failure was not significantly different between the cell salvage group (98.4%, 95% CI 95.3–99.9%) and the control group (95.3%, 95% CI 90.2–99.9%) at one year (log rank, P = .330). The rates of postoperative ABT in the cell salvage group were significantly lower than those in the control group (11.5% vs 26.6%, P = .041). In multivariable models, patient age, body mass index, preoperative hemoglobin level, and intraoperative cell salvage were independent predictors of ABT exposure (P < .05). Conclusions The use of cell salvage during reimplantation in two-stage exchange for chronic hip PJI did not appear to increase the reinfection rate, while it significantly reduced the rate of postoperative allogeneic red blood transfusion. Greater age, lower BMI, lower preoperative hemoglobin, and non-intraoperative cell salvage reinfusion were associated with higher rate of allogeneic red blood transfusion.

Intraoperative transfusion practices and perioperative outcome in the European elderly: A secondary analysis of the observational ETPOS study. PLoS One 2022; 17:e0262110.

Abstract
The demographic development suggests a dramatic growth in the number of elderly patients undergoing surgery in Europe. Most red blood cell transfusions (RBCT) are administered to older people, but little is known about perioperative transfusion practices in this population. In this secondary analysis of the prospective observational multicentre European Transfusion Practice and Outcome Study (ETPOS), we specifically evaluated intraoperative transfusion practices and the related outcomes of 3149 patients aged 65 years and older. Enrolled patients underwent elective surgery in 123 European hospitals, received at least one RBCT intraoperatively and were followed up for 30 days maximum. The mean haemoglobin value at the beginning of surgery was 108 (21) g/l, 84 (15) g/l before transfusion and 101 (16) g/l at the end of surgery. A median of 2 [1-2] units of RBCT were administered. Mostly, more than one transfusion trigger was present, with physiological triggers being preeminent. We revealed a descriptive association between each intraoperatively administered RBCT and mortality and discharge respectively, within the first 10 postoperative days but not thereafter. In our unadjusted model the hazard ratio (HR) for mortality was 1.11 (95% CI: 1.08-1.15) and the HR for discharge was 0.78 (95% CI: 0.74-0.83). After adjustment for several variables, such as age, preoperative haemoglobin and blood loss, the HR for mortality was 1.10 (95% CI: 1.05-1.15) and HR for discharge was 0.82 (95% CI: 0.78-0.87). Pre-operative anaemia in European elderly surgical patients is undertreated. Various triggers seem to support the decision for RBCT. A closer monitoring of elderly patients receiving intraoperative RBCT for the first 10 postoperative days might be justifiable. Further research on the causal relationship between RBCT and outcomes and on optimal transfusion strategies in the elderly population is warranted. A thorough analysis of different time periods within the first 30 postoperative days is recommended.

Abstract
Gastrointestinal bleeding is a common clinical problem encountered in both the inpatient and outpatient settings. Although the evaluation of upper and lower gastrointestinal bleeding is often straightforward, bleeding from the small bowel may pose a clinical challenge. In this article, we review the indications, modalities, and differential diagnoses of small bowel bleeding. On completion of the article, clinicians should be able to identify common causes of small bowel bleeding, understand the advantages and disadvantages of the modalities used to evaluate small bowel bleeding, and enact a stepwise management approach to the patient with presumed small bowel bleeding.

Abstract
Melatonin is an indole-like neuroendocrine hormone. A large number of studies have shown that melatonin can improve production performance of ewes, but it is not clear in lambs. In this study, the growth and development of the 2-month-old lambs implanted with melatonin were monitored for 60 days. The results showed that the growth rate of body weight and body skew length of lambs with melatonin treatment were significantly improved compared to the controls. The similar results were also observed in red blood cell count, hematocrit, red blood cell volume distribution width, the levels of growth hormone, testosterone, immunoglobulin A, immunoglobulin M and albumin. In addition, the cross sectional area of muscle fibers and adipose cells of lambs with melatonin implantation were also significantly increased compared to the controls (P<0.05). To further explore the potential mechanisms, the muscle and adipose tissue were selected for transcriptome sequencing. KEGG enrichment results showed that melatonin regulated the expression of genes related to apoptotic signaling pathway in muscle and adipocytes. Since the intestinal microbiota are involved in the nutritional balance and animal growth, the 16SrRNA sequencing related to the intestinal microbiota was also performed. The data indicated that the structural differences of fecal microflora mainly occur in the pathways of Cardiovascular disease, Excretory system and Signaling molecules and interaction. In brief, melatonin promotes the growth and development of lambs. The potential mechanisms may be that melatonin increased the growth hormone and testosterone mediated apoptosis signaling pathway and regulated intestinal microbial flora. Our results provide valuable information for melatonin to improve the production of sheep husbandry in the future.

Abstract
BACKGROUND The optimal haemoglobin threshold for use of red blood cell (RBC) transfusions in anaemic patients remains an active field of research. Blood is a scarce resource, and in some countries, transfusions are less safe than in others because of inadequate testing for viral pathogens. If a liberal transfusion policy does not improve clinical outcomes, or if it is equivalent, then adopting a more restrictive approach could be recognised as the standard of care. OBJECTIVES: The aim of this review update was to compare 30-day mortality and other clinical outcomes for participants randomised to restrictive versus liberal red blood cell (RBC) transfusion thresholds (triggers) for all clinical conditions. The restrictive transfusion threshold uses a lower haemoglobin concentration as a threshold for transfusion (most commonly, 7.0 g/dL to 8.0 g/dL), and the liberal transfusion threshold uses a higher haemoglobin concentration as a threshold for transfusion (most commonly, 9.0 g/dL to 10.0 g/dL). SEARCH METHODS We identified trials through updated searches: CENTRAL (2020, Issue 11), MEDLINE (1946 to November 2020), Embase (1974 to November 2020), Transfusion Evidence Library (1950 to November 2020), Web of Science Conference Proceedings Citation Index (1990 to November 2020), and trial registries (November 2020). We checked the reference lists of other published reviews and relevant papers to identify additional trials. We were aware of one trial identified in earlier searching that was in the process of being published (in February 2021), and we were able to include it before this review was finalised. SELECTION CRITERIA We included randomised trials of surgical or medical participants that recruited adults or children, or both. We excluded studies that focused on neonates. Eligible trials assigned intervention groups on the basis of different transfusion schedules or thresholds or 'triggers'. These thresholds would be defined by a haemoglobin (Hb) or haematocrit (Hct) concentration below which an RBC transfusion would be administered; the haemoglobin concentration remains the most commonly applied marker of the need for RBC transfusion in clinical practice. We included trials in which investigators had allocated participants to higher thresholds or more liberal transfusion strategies compared to more restrictive ones, which might include no transfusion. As in previous versions of this review, we did not exclude unregistered trials published after 2010 (as per the policy of the Cochrane Injuries Group, 2015), however, we did conduct analyses to consider the differential impact of results of trials for which prospective registration could not be confirmed. DATA COLLECTION AND ANALYSIS: We identified trials for inclusion and extracted data using Cochrane methods. We pooled risk ratios of clinical outcomes across trials using a random-effects model. Two review authors independently extracted data and assessed risk of bias. We conducted predefined analyses by clinical subgroups. We defined participants randomly allocated to the lower transfusion threshold as being in the 'restrictive transfusion' group and those randomly allocated to the higher transfusion threshold as being in the 'liberal transfusion' group. MAIN RESULTS A total of 48 trials, involving data from 21,433 participants (at baseline), across a range of clinical contexts (e.g. orthopaedic, cardiac, or vascular surgery; critical care; acute blood loss (including gastrointestinal bleeding); acute coronary syndrome; cancer; leukaemia; haematological malignancies), met the eligibility criteria. The haemoglobin concentration used to define the restrictive transfusion group in most trials (36) was between 7.0 g/dL and 8.0 g/dL. Most trials included only adults; three trials focused on children. The included studies were generally at low risk of bias for key domains including allocation concealment and incomplete outcome data. Restrictive transfusion strategies reduced the risk of receiving at least one RBC transfusion by 41% across a broad range of clinical contexts (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.53 to 0.66; 42 studies, 20,057 participants; high-quality evidence), with a large amount of heterogeneity between trials (I² = 96%). Overall, restrictive transfusion strategies did not increase or decrease the risk of 30-day mortality compared with liberal transfusion strategies (RR 0.99, 95% CI 0.86 to 1.15; 31 studies, 16,729 participants; I² = 30%; moderate-quality evidence) or any of the other outcomes assessed (i.e. cardiac events (low-quality evidence), myocardial infarction, stroke, thromboembolism (all high-quality evidence)). High-quality evidence shows that the liberal transfusion threshold did not affect the risk of infection (pneumonia, wound infection, or bacteraemia). Transfusion-specific reactions are uncommon and were inconsistently reported within trials. We noted less certainty in the strength of evidence to support the safety of restrictive transfusion thresholds for the following predefined clinical subgroups: myocardial infarction, vascular surgery, haematological malignancies, and chronic bone-marrow disorders. AUTHORS' CONCLUSIONS Transfusion at a restrictive haemoglobin concentration decreased the proportion of people exposed to RBC transfusion by 41% across a broad range of clinical contexts. Across all trials, no evidence suggests that a restrictive transfusion strategy impacted 30-day mortality, mortality at other time points, or morbidity (i.e. cardiac events, myocardial infarction, stroke, pneumonia, thromboembolism, infection) compared with a liberal transfusion strategy. Despite including 17 more randomised trials (and 8846 participants), data remain insufficient to inform the safety of transfusion policies in important and selected clinical contexts, such as myocardial infarction, chronic cardiovascular disease, neurological injury or traumatic brain injury, stroke, thrombocytopenia, and cancer or haematological malignancies, including chronic bone marrow failure. Further work is needed to improve our understanding of outcomes other than mortality. Most trials compared only two separate thresholds for haemoglobin concentration, which may not identify the actual optimal threshold for transfusion in a particular patient. Haemoglobin concentration may not be the most informative marker of the need for transfusion in individual patients with different degrees of physiological adaptation to anaemia. Notwithstanding these issues, overall findings provide good evidence that transfusions with allogeneic RBCs can be avoided in most patients with haemoglobin thresholds between the range of 7.0 g/dL and 8.0 g/dL. Some patient subgroups might benefit from RBCs to maintain higher haemoglobin concentrations; research efforts should focus on these clinical contexts.

Abstract
Background Gastrointestinal cancer demands a high frequency of transfusions, and the high availability of blood products. We aimed to determine the frequency of blood transfusions and the most used blood products according to the type of gastrointestinal cancer. Methods A cross-sectional study was conducted in a Peruvian Type I Hemotherapy and Blood Bank Service of a Private Oncological Clinic during 2016–2018. We included patients with gastrointestinal cancer using the International Code of Diseases. The donations were made in compliance with the requirements of the Programa Nacional de Hemoterapía y Banco de Sangre and in accordance with the Standardised Operational Procedure of the clinic. Results We analysed 3,022 patients, of which 163 (5.4%) had gastrointestinal cancer (67.1 ± 12 years). The 80 (49.1%) men did not show significant differences with the 83 (50.9%) women (p = 0.178). The most frequent neoplasia was the colon (41.7%) and pancreas (37.4%). Three hundred and four blood products were transfused (average 1.8 ± 2.5 units (range: 1–30 units/patient)), of which 81.3% (247 units) were red blood cells concentrated, 8.6% (26 units) were fresh-frozen-plasma (FFP) and 6.6% (20 units) were cryoprecipitate. The type of cancer that most blood products demanded was colon neoplasia (41.8%), followed by pancreatic cancer (26.3%) and liver cancer (10.9%). We determined that ~55% of patients were O Rh(D)+ and in five patients we were poly-transfused. Conclusion Our findings suggested that patients with gastrointestinal cancer require large numbers of transfusions of blood cell concentrate and FFP. Also, we showed that cancer of the colon, pancreas and liver demanded more than 75% of blood products.

Abstract
OBJECTIVES To assess transfusion practices at a Canadian tertiary care center before and after a hospital-wide blood management educational campaign based on the Choosing Wisely toolkit. BACKGROUND Red blood cell (RBC) transfusions are an essential intervention in obstetrics and gynaec ology (O&G). However, with limited guidelines outlining the appropriate use of RBC transfusions, clinicians routinely transfuse based on haemoglobin values and habits. METHODS/MATERIALS We conducted a retrospective chart review of all patients who received a RBC transfusion while admitted under an O&G provider in two 12-month periods-before and after the intervention. The campaign consisted of Grand Rounds, formal and informal teaching, and posters placed within the hospital. We judged appropriateness from a set of criteria guided by the status of ongoing bleeding, pre-transfusion haemoglobin, and the number of units ordered simultaneously. RESULTS Transfusion appropriateness was poor in pre- and post-intervention periods (46% vs. 51%, p = 0.59). The overall rate of RBC transfusion was reduced from 1.8% to 1.2% (83/4610 vs. 55/4618, p = 0.02) after the intervention. There was a 52% reduction in the total number of RBC units of transfused (229 vs. 111, p < 0.001), a 33% reduction in the number of patients transfused (83 vs. 55, p = 0.016), and fewer multiple-unit transfusions without reassessment (39 vs. 13, p = 0.005). CONCLUSION RBC transfusion appropriateness remained low after a hospital-wide educational campaign. However, there was a marked decrease in overall transfusion use, reflecting the adoption of more restrictive transfusion practices. The low rate of transfusion appropriateness represents an opportunity for further improvement.

Abstract
VEXAS syndrome has an unmet need for therapeutic interventions. Even if few data exist regarding the treatment of this newly described syndrome, different options can be proposed given the unique pathophysiological consequences of the clonal dominance of UBA1 mutated hematopoietic stem cells. To date, allogeneic transplantation is the only curative option, but many questions remain regarding the selection of eligible patients, the conditioning regimen or management of toxicities that may be unique to VEXAS patients. Alternatively, drugs used in myelodysplastic syndrome such as hypomethylating agents or lenalidomide are interesting candidates, which could theoretically have also an effect on the clone. Another strategy is to target the inflammatory cascade, by inhibiting proinflammatory cytokines (such as TNFα, IL1, IL6) or effector cells, for example with JAK inhibitors. Whatever the choice of treatment for VEXAS patients, supportive care is always needed to be considered to manage frequent complications such as cytopenia, thrombosis and infections. Finally, we discuss the challenges of the design of clinical trials for VEXAS patients, from inclusion criteria to clinical and biological endpoints of activity.

[PMID: 34810091 DOI: 10.1016/j.transci.2021.103323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Revised: 11/08/2021] [Accepted: 11/13/2021] [Indexed: 11/15/2022]
Abstract
INTRODUCTION Red blood cell (RBC) transfusion (RBCT) is one of the most frequently performed procedures in inpatients within modern hospital systems. However transfusion practices may vary by an institution or even by a prescribing physician. In order to assess the current RBCT practice in our institution, we performed a detailed analysis of RBCTs. MATERIAL AND METHODS We performed a retrospective analysis of all RBCTs in our institution between January 2018 and December 2019. The data collected included: age, sex, type of RBC, number of single and multiple unit RBCTs in bleeding and nonbleeding patients, number of multiple unit RBCTs in non-bleeding patients with and without hemoglobin (Hb) concentration determination after each RBC, primary indication for RBCT, pre-post RBCT Hb concentration in non-bleeding patients, lactate concentration pre-post RBCT in non-bleeding patients. RESULTS The indications for RBCT were anemia (2244, 56.2 % RBC) and bleeding (1463, 36.6 % RBC). The most frequently used types of RBCs were RBCs without buffy coat (75.1 %) and leucodepleted RBCs (20.9 %). In non-bleeding patients 45.7 % were multiple unit RBCTs, only 3% were performed with Hb determination following the first unit of RBC, 508 (20.2 %) RBCT were performed with pre-post RBCT lactate concentration determination. CONCLUSIONS Analysis of the local RBCT practice showed significant room for improvement. Areas of concern were type of RBC ordered, multiple unit transfusions in non-bleeding patients, lack of laboratory control of oxygenation pre-post transfusion or not taking it into account in RBCT decision making. Deficiencies are planned to be addressed by a comprehensive blood utilization review programme.

Abstract
As the number of cancer cases rise each year in Canada, so does the number of surgical oncology cases. Surgery presents a unique and heightened stressor for the body already experiencing volatility from factors such as disease and treatments. Perioperative red blood cell (RBC) transfusions are critical to stabilize hemoglobin levels and correct anemia, as well as provide a buffer against anticipated intraoperative blood loss. Thoroughly examining and anticipating risk factors related to the potential need for perioperative blood transfusions is necessary to improve outcomes. Research evidence in recent years related to perioperative blood management of oncology patients has specifically recommended active, coordinated programs to reduce the need and amount of blood transfusions administered pre-, intra-, and post-surgery. Coordination between surgical oncologists and a local or provincial patient blood management (PBM) program is an important strategy that allows patients at risk of perioperative complications to be identified and receive early interventions and ongoing observation.

Abstract
Au Canada, le nombre de cas de cancer augmente chaque année et, par conséquent, le nombre de patients en oncologie qui subissent une opération. La chirurgie cause un stress particulièrement intense à l’organisme déjà fragilisé par la maladie et les traitements. Les transfusions périopératoires de globules rouges sont essentielles pour stabiliser le taux d’hémoglobine et soigner l’anémie, ainsi que pour gérer la perte de sang attendue pendant l’opération. Il est nécessaire d’examiner en profondeur et d’anticiper les facteurs de risque associés aux transfusions sanguines périopératoires pour améliorer le devenir des patients. Ces dernières années, la recherche sur la gestion périopératoire du sang des patients en oncologie recommande tout spécialement la création de programmes d’intervention coordonnés pour réduire la nécessité et le nombre de transfusions sanguines administrées avant, pendant et après l’opération. Pour recenser les patients à risque de complications périopératoires et leur faire bénéficier d’interventions rapides et d’une observation continue, la bonne stratégie est de mettre en lien les chirurgiens oncologues avec un programme local ou provincial de conservation du sang.

Abstract
ABSTRACT The transfusion of blood products is a widely used practice but comes with the risk of transfusion-associated adverse events and fatalities. The primary aim of this study was to evaluate if strict adherence to transfusion guidelines would lead to a decrease in the rate of transfusion reactions that occurred when blood products were given outside of established indications. Hospital-wide educational programs and dedicated electronic transfusion order sets were used to encourage adherence to guidelines. A secondary aim of this study was to evaluate if a decrease in the incidence of transfusion reactions also lead to a decrease in associated healthcare costs.

Abstract
Background Tranexamic acid (TXA) reduces blood loss in knee and hip arthroplasty, but the effectiveness in shoulder arthroplasty is unknown. This study aimed to evaluate current level I randomized controlled trials examining the efficacy of TXA in primary shoulder arthroplasty. Methods A protocol for the study was designed and registered with PROSPERO (CRD42021230398). The PubMed, Embase, and Cochrane Library databases were searched using the following search strategy: "shoulder replacement" OR "shoulder arthroplasty" OR "reverse shoulder arthroplasty" AND "tranexamic acid." All randomized controlled trials were included in this study. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was followed. Outcomes include blood loss, drain output, hemoglobin, thromboembolic complications, and blood transfusion. Results Five randomized controlled trials of 435 patients (219 patients in the TXA group and 216 patients in the non-TXA group) were included in the systematic review. The results indicated that the group using TXA had less total blood loss (MD, -249.56 mL; 95% confidence interval [CI] -347.60 to -151.52), less drainage output (MD, -113.72 mL; -155.92 to -71.52 95% CI), and less of a change in hemoglobin (MD, -0.68 g/dl; -0.94 to -0.42 g/dl 95% CI). No significant differences in blood transfusion (risk ratio 0.40; -0.11 to 1.45 95% CI) or thromboembolic events (risk ratio 0.13, 0.02 to 1.12 95% CI) were observed. Subgroup analyses showed that there was no significant difference in total blood loss, drainage output, or change in hemoglobin between single dose and multiple doses. Conclusions TXA in primary shoulder arthroplasty can reduce blood loss, drain output, and hemoglobin changes. Subgroup analysis showed that multiple TXA doses have similar results compared with single dose in primary shoulder arthroplasty. More randomized controlled trials comparing different administration routes of TXA in primary and revision shoulder arthroplasty are required.

Abstract
This study was a prospective, observational study aimed to look at the preoperative ordering schedule, pattern of usage of blood products for elective oncological surgeries in order to develop an institutional maximal surgical blood ordering schedule (MSBOS) in a tertiary university setting teaching Hospital. All biopsy proven, consenting, cancer patients of age 18 to 80 years who underwent elective curative cancer surgery over a period of 1 year were included. Various details such as nature of procedure, preoperative haemoglobin, intraoperative blood loss, duration of surgery, and number of units cross-matched and used were recorded and analysed. For each procedure, cross-match to transfusion (CT) ratio, transfusion index (TI), and transfusion probability (T%) were calculated using standard formulas. In all, 740 patients underwent elective curative cancer surgery in 1 year, majority being women and head and neck cancer being most common site. Overall, 312 patients received blood or component transfusion in the intraoperative and/or postoperative (within 48 h) period constituting 42% of all patients, although 70% of patients had preserved packed cells and 55% had preserved fresh frozen plasma (FFP). Cross-matching of blood was adequate only in cases of liver surgeries, maxillectomy, staging laparotomy for ovarian carcinoma, and urological malignancies with a desirable CT ratio falling within 2.5. An institution specific-MSBOS was developed. The study found a significant over-ordering of blood products. By implementing MSBOS, one can plan the collection and stocking of blood products thereby saving money, labour, and time.

Abstract
OBJECTIVE To study the clinical outcomes of red blood cell (RBC) transfusion practices in critically ill children. METHOD This prospective cohort study was conducted in a tertiary care pediatric intensive care unit (PICU) from March-2015 to January-2018. Inverse probability of treatment weighting (IPTW) using propensity score analysis was used. Children aged 1 mo to 12 y admitted to the PICU were screened. Patients were classified into 'transfused' and 'nontransfused', based on whether they received a transfusion or not. Patients with hematological malignancies, or immunosuppressant drugs, or those who received repeated transfusions, or received transfusion before admission, or died within 24 h were excluded. The primary outcome was all-cause 28 d mortality. Secondary outcomes were new-onset organ dysfunction, mechanical ventilation duration, and length of PICU and hospital stay. RESULTS A total of 1014 patients [transfused = 277; nontransfused = 737) were included. In IPTW analysis, the risk of all-cause 28 d mortality was 53% higher in transfused than nontransfused patients [hazard ratio = 1.53, 95% CI: 1.18-1.98, p = 0.001 by Log-rank test]. Organ dysfunction was higher in transfused than nontransfused patients [3.8% vs. 1.3%, hazard ratio = 3.0, 95% CI: 1.40-6.48, p = 0.005]. The risk of staying in the mechanical ventilation was similar in both groups [hazard ratio = 1.03, 95% CI: 0.86-1.23, p = 0.756]. The risk of extended stay in the PICU and hospital was 16% and 21% higher in transfused than nontransfused patients [hazard ratio = 1.16, 95% CI: 1.03-1.30; p = 0.005; and 1.21, 95% CI: 1.08-1.36; p = 0.001], respectively. CONCLUSION Red blood cell transfusion was independently associated with higher all-cause 28 d mortality and morbidities in critically ill children.

Abstract
OBJECTIVES For anaemic elective surgery patients, current clinical practice guidelines weakly recommend the routine use of iron, but not erythrocyte-stimulating agents (ESAs), except for short-acting ESAs in major orthopaedic surgery. This recommendation is, however, not based on any cost-effectiveness studies. The aim of this research was to (1) systematically review the literature regarding cost effectiveness of preoperative iron and/or ESAs in anaemic, elective surgery patients and (2) update existing economic evaluations (EEs) with recent data. METHODS Eight databases and registries were searched for EEs and randomized controlled trials (RCTs) reporting cost-effectiveness data on November 11, 2020. Data were extracted, narratively synthesized and critically appraised using the Philips reporting checklist. Pre-existing full EEs were updated with effectiveness data from a recent systematic review and current cost data. Incremental cost-effectiveness ratios were expressed as cost per (quality-adjusted) life-year [(QA)LY] gained. RESULTS Only five studies (4 EEs and 1 RCT) were included, one on intravenous iron and four on ESAs + oral iron. The EE on intravenous iron only had an in-hospital time horizon. Therefore, cost effectiveness of preoperative iron remains uncertain. The three EEs on ESAs had a lifetime time horizon, but reported cost per (QA)LY gained of 20-65 million (GBP or CAD). Updating these analyses with current data confirmed ESAs to have a cost per (QA)LY gained of 3.5-120 million (GBP or CAD). CONCLUSIONS Cost effectiveness of preoperative iron is unproven, whereas routine preoperative ESA therapy cannot be considered cost effective in elective surgery, based on the limited available data. Future guidelines should reflect these findings.

Abstract
BACKGROUND Hip fractures are associated with serious morbidity and mortality. Low haemoglobin at presentation has been shown to be associated with increased mortality in hip fracture patients. This comorbid patient group commonly receives packed red cell blood transfusions during their hospital admission, the impact of which is less clear. AIMS AND OBJECTIVES We aim to assess the rate, appropriateness and impact of blood transfusions on one-year mortality in hip fracture patients. We also aim to assess the impact of patients taking anticoagulant medications at presentation on the rates of blood transfusions in this patient group. METHODS A retrospective cohort study of 324 consecutive hip fracture patients. Data was collected from the national hip fracture database, electronic patient records and PACS. RESULTS 75 patients received a blood transfusion. Receiving a blood transfusion increased absolute risk of one-year mortality by 2.466 (p < 0.05). Adjusted for age, sex, comorbidities, residence prior to admission and time from presentation to surgery increased the risk of one-year mortality was 2.790 (p < 0.05).28% of patients who went on to receive a transfusion had a haemoglobin of less than 100 g/L at presentation. 94.6% of transfused patients had a pre-transfusion haemoglobin of less than 90 g/L. There was no increased risk of requiring a blood transfusion if anticoagulant medication was being taken at presentation. CONCLUSION Receiving a blood transfusion during an admission for hip fracture carried an increased risk of one-year mortality of almost two and a half times. With appropriate preoperative optimisation, taking an anticoagulant medication at presentation did not increase the risk of requiring a transfusion. Most blood transfusions were administered appropriately using thresholds. Just over a quarter of patients who received a transfusion had an admission haemoglobin of less than 100 g/L, showing it as a poor predictor of blood transfusion requirement during admission.

Abstract
Various studies have established the prognosis of anemia in myocardial infarction (MI). Both chronic and acute anemia lead to poor outcomes in MI. Regardless, the association of anemia with MI and its management varies. In this study, the literature was analyzed to determine the association between acute anemia and MI based on the pathophysiology, outcomes, and management options. Acute anemia results in decreased blood supply and sudden hypoxia to the heart. Additionally, it exacerbates the preexisting compromised coronary blood supply in patients with MI. Thus, there is a disproportionate oxygen supply and demand ratio to the heart. It was found that anemia increases all-cause mortality in acute MI. However, it is unclear whether anemia is the direct contributor to mortality in these patients. For the management of MI, percutaneous coronary intervention (PCI) is commonly used. Increased incidence of hospital-acquired anemia (HAA) is reported in patients after PCI. However, the cause of HAA in these patients is not well established. Antiplatelet therapy in these patients is also considered to be the culprit for HAA. Nonetheless, no clear evidence is available. There is no consensus or criteria for the treatment of acute anemia in MI patients. Researchers have explored management options such as blood transfusion, erythropoietin-stimulating agent, and iron therapy. Further studies are warranted for a better understanding and management of MI in patients with anemia and vice versa.

Abstract
BACKGROUND Tranexamic acid (TXA) is widely used across surgical specialties to reduce perioperative bleeding. It has been shown to be effective in spinal surgery and lower limb arthroplasty. Among all languages, there are no systematic reviews or meta-analyses investigating its clinical effectiveness for all types of shoulder surgery. PURPOSE To investigate the clinical effectiveness of TXA in all types of shoulder surgery, including open and arthroscopic procedures. To investigate the effect of TXA on bleeding and non-bleeding-related outcomes. STUDY DESIGN Systematic review and meta-analysis. METHODS A protocol for the study was designed and registered with PROSPERO (CRD42020185482). The literature search included the MEDLINE, Embase, PsycINFO, and Cochrane Library databases. All randomized controlled trials evaluating the use of TXA against placebo, in all types of shoulder surgery, were included. Assessments were undertaken for risk of bias and certainty of evidence. The primary outcome was total blood loss. Secondary outcomes included those not directly related to bleeding. Data from comparable outcomes were pooled and analyzed quantitatively or descriptively, as appropriate. RESULTS Eight randomized controlled trials were included in the systematic review, and data from 7 of these studies were pooled in the meta-analysis. Pooled analysis demonstrated a significant reduction in 2 of 3 outcomes measuring perioperative bleeding with TXA compared with controls: estimated total blood loss (mean difference, -209.66 mL; 95% CI, -389.11 to -30.21; P = .02) and postoperative blood loss as measured by drain output (mean difference, -84.8 mL; 95% CI, -140.04 to -29.56; P = .003). Hemoglobin reduction was reduced but not statistically significant (mean difference, -0.33 g/dL; 95% CI -0.69 to 0.03; P = .07). This result became significant with sensitivity analysis excluding arthroscopic procedures. CONCLUSION This systematic review and meta-analysis indicated that TXA was effective in reducing blood loss in shoulder surgery. Larger randomized controlled trials with low risk of bias for specific surgical shoulder procedures are required. CLINICAL RELEVANCE TXA can be used across shoulder surgery to reduced perioperative blood loss. The use of TXA may have other beneficial features, including reduced postoperative pain and reduced operative time.

Br J Anaesth 2021; 127:405-414. [PMID: 34229832 DOI: 10.1016/j.bja.2021.05.031] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 05/08/2021] [Accepted: 05/08/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Allogeneic red blood cell (RBC) transfusion can induce immunosuppression, which can then increase the susceptibility to postoperative infection. However, studies in different types of surgery show conflicting results regarding this effect. METHODS In this retrospective cohort study conducted in a tertiary referral centre, we included adult patients undergoing clean-contaminated surgery from 2014 to 2018. Patients who received allogeneic RBC transfusion from preoperative Day 30 to postoperative Day 30 were included into the transfusion group. The control group was matched for the type of surgery in a 1:1 ratio. The primary outcome was infection within 30 days after surgery, which was defined by healthcare-associated infection, and identified mainly based on antibiotic regimens, microbiology tests, and medical notes. RESULTS Among the 8098 included patients, 1525 (18.8%) developed 1904 episodes of postoperative infection. Perioperative RBC transfusion was associated with an increased risk of postoperative infection after controlling for 27 confounders by multivariable regression analysis (odds ratio [OR]: 1.60; 95% confidence interval [CI]: 1.39-1.84; P<0.001) and propensity score weighing (OR: 1.64; 95% CI: 1.45-1.85; P<0.001) and matching (OR: 1.70; 95% CI: 1.43-2.01; P<0.001), and a dose-response relationship was observed. The transfusion group also showed higher risks of surgical site infection, pneumonia, bloodstream infection, multiple infections, intensive care admission, unplanned reoperation, prolonged postoperative length of hospital stay, and all-cause death. CONCLUSIONS Perioperative allogeneic RBC transfusion is associated with an increased risk of infection after clean-contaminated surgery in a dose-response manner. Close monitoring of infections and enhanced prophylactic strategies should be considered after transfusion.

JMIRX MED 2021; 2:e27017. [PMID: 37725533 PMCID: PMC10414364 DOI: 10.2196/27017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 04/03/2021] [Accepted: 05/01/2021] [Indexed: 09/21/2023]
Abstract
BACKGROUND Big data tools provide opportunities to monitor adverse events (patient harm associated with medical care) (AEs) in the unstructured text of electronic health care records (EHRs). Writers may explicitly state an apparent association between treatment and adverse outcome ("attributed") or state the simple treatment and outcome without an association ("unattributed"). Many methods for finding AEs in text rely on predefining possible AEs before searching for prespecified words and phrases or manual labeling (standardization) by investigators. We developed a method to identify possible AEs, even if unknown or unattributed, without any prespecifications or standardization of notes. Our method was inspired by word-frequency analysis methods used to uncover the true authorship of disputed works credited to William Shakespeare. We chose two use cases, "transfusion" and "time-based." Transfusion was chosen because new transfusion AE types were becoming recognized during the study data period; therefore, we anticipated an opportunity to find unattributed potential AEs (PAEs) in the notes. With the time-based case, we wanted to simulate near real-time surveillance. We chose time periods in the hope of detecting PAEs due to contaminated heparin from mid-2007 to mid-2008 that were announced in early 2008. We hypothesized that the prevalence of contaminated heparin may have been widespread enough to manifest in EHRs through symptoms related to heparin AEs, independent of clinicians' documentation of attributed AEs. OBJECTIVE We aimed to develop a new method to identify attributed and unattributed PAEs using the unstructured text of EHRs. METHODS We used EHRs for adult critical care admissions at a major teaching hospital (2001-2012). For each case, we formed a group of interest and a comparison group. We concatenated the text notes for each admission into one document sorted by date, and deleted replicate sentences and lists. We identified statistically significant words in the group of interest versus the comparison group. Documents in the group of interest were filtered to those words, followed by topic modeling on the filtered documents to produce topics. For each topic, the three documents with the maximum topic scores were manually reviewed to identify PAEs. RESULTS Topics centered around medical conditions that were unique to or more common in the group of interest, including PAEs. In each use case, most PAEs were unattributed in the notes. Among the transfusion PAEs was unattributed evidence of transfusion-associated cardiac overload and transfusion-related acute lung injury. Some of the PAEs from mid-2007 to mid-2008 were increased unattributed events consistent with AEs related to heparin contamination. CONCLUSIONS The Shakespeare method could be a useful supplement to AE reporting and surveillance of structured EHR data. Future improvements should include automation of the manual review process.

Abstract
BACKGROUND The incidence of transfusion in contemporary revision total hip arthroplasty (THA) remains high despite recent advances in blood management, including the use of tranexamic acid. The purpose of this prospective investigation was to determine independent risk factors for transfusion in revision THA. METHODS Six centers prospectively collected data on 175 revision THAs. A multivariable logistic analysis was performed to determine independent risk factors for transfusion. Revisions were categorized into subgroups for analysis, including femur-only, acetabulum-only, both-component, explantation with spacer, and second-stage reimplantation. Patients undergoing an isolated modular exchange were excluded. RESULTS Twenty-nine patients required at least one unit of blood (16.6%). In the logistic model, significant risk factors for transfusion were lower preoperative hemoglobin, higher preoperative international normalized ratio (INR), and longer operative time (P < .01, P = .04, P = .05, respectively). For each preoperative 1g/dL decrease in hemoglobin, the chance of transfusion increased by 79%. For each 0.1-unit increase in the preoperative INR, transfusion chance increased by 158%. For each additional operative hour, the chance of transfusion increased by 74%. There were no differences in transfusion rates among categories of revision hip surgery (P = .23). No differences in demographic or surgical variables were found between revision types. CONCLUSION Despite the use of tranexamic acid, transfusions are commonly required in revision THA. Preoperative hemoglobin and INR optimization are recommended when medically feasible. Efforts should also be made to decrease operative time when technically possible.

Abstract
This study evaluated whether the type of anesthesia independently related to risk of blood transfusion events in patients undergoing total knee arthroplasty (TKA) after adjusting for other covariates. This was a secondary analysis of a retrospective cohort study of patients undergoing primary unilateral TKA in Singapore. The independent variable was the type of anesthesia and the dependent variable was blood transfusion events. A multivariable logistic regression analysis was performed adjusting for variables that might affect the choice of anesthesia or blood transfusion events. Additional analyses examined this association by the subgroup analysis by using stratified multivariate logistic regression models. Of all 2,366 patients undergoing primary unilateral TKA, 120 (5.1%) developed blood transfusion events. Sixty-four (4.1%) of 1,560 patients with regional anesthesia (RA) developed blood transfusion events, compared with 56 (6.9%) of 806 patients with general anesthesia (GA; (p = 0.003). After adjusting for age, sex, preoperative hemoglobin, and other variables, patients who received RA had a decreased risk of blood transfusion events compared with those receiving GA (odds ratio [OR]: 0.53, 95% confidence interval [CI]: 0.35-0.81). This risk further decreased in male (OR: 0.20, 95% CI: 0.07-0.59) and participants whose operation time ≥ 90 minutes (OR: 0.39, 95% CI: 0.19-0.78). Our results indicated that patients receiving primary unilateral TKA who were managed with RA had a significantly decreased risk of blood transfusion events compared with those with GA, especially in male and participants whose operation time ≥ 90 minutes.

Abstract
BACKGROUND Acetabular fracture open reduction and internal fixation (ORIF) is generally associated with high intraoperative blood loss. Hypotensive anesthesia has been shown to decrease blood loss and intraoperative transfusion in total joint arthroplasty and posterior spinal fusion. In this study, we assessed the effect of reduction in intraoperative mean arterial pressures (MAPs) during acetabular fracture surgery on intraoperative blood loss and need for transfusion. METHODS Three hundred and one patients with acetabular fractures who underwent ORIF at an academic Level 1 trauma center were retrospectively reviewed. Patients were separated based on mean intraoperative MAPs (<60 mmHg, 60-70 mmHg, >70 mmHg). Thirteen patients had mean intraoperative MAP <60 mmHg, 95 had MAP 60-70 mmHg, and 193 had MAP >70 mmHg. Rates of intraoperative and postoperative allogeneic blood transfusion were compared. RESULTS Mean intraoperative MAPs were significantly different between groups (p < 0.0001). Time from injury to surgery, estimated blood loss, operative time and intraoperative IV fluids were comparable. The proportion of patients who received blood transfusion and mean units transfused intraoperatively and postoperatively were similar between groups. Mean differences in preoperative and postoperative hemoglobin and hematocrit were also similar. There was no difference in hospital length of stay or perioperative complications between the groups. Multivariate logistic regression analysis demonstrated that body mass index > 30 (p < 0.05) and anterior surgical approach (p < 0.01) were independently associated with intraoperative transfusion and an anterior surgical approach (p < 0.001) was independently associated with postoperative transfusion. CONCLUSION Decreased intraoperative MAP during acetabular fracture surgery does not reduce blood loss or need for transfusion. On the other hand, no increased end-organ ischemia was seen with hypotensive anesthesia. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
OBJECTIVES The objective of this work was to carry out a systematic review of clinical practice guidelines (CPGs) pertaining to intraoperative red blood cell (RBC) transfusions, in terms of indications, decision-making, and supporting evidence base. SUMMARY OF BACKGROUND DATA RBC transfusions are common during surgery and there is evidence of wide variability in practice. METHODS Major electronic databases (MEDLINE, EMBASE, and CINAHL), guideline clearinghouses and Google Scholar were systematically searched from inception to January 2019 for CPGs pertaining to indications for intraoperative RBC transfusion. Eligible guidelines were retrieved and their quality assessed using AGREE II. Relevant recommendations were abstracted and synthesized to allow for a comparison between guidelines. RESULTS Ten guidelines published between 1992 and 2018 provided indications for intraoperative transfusions. No guideline addressed intraoperative transfusion decision-making as its primary focus. Six guidelines provided criteria for transfusion based on hemoglobin (range 6.0-10.0 g/dL) or hematocrit (<30%) triggers. In the absence of objective transfusion rules, CPGs recommended considering other parameters such as blood loss (n = 7), signs of end organ ischemia (n = 5), and hemodynamics (n = 4). Evidence supporting intraoperative recommendations was extrapolated primarily from the nonoperative setting. There was wide variability in the quality of included guidelines based on AGREE II scores. CONCLUSION This review has identified several clinical practice guidelines providing recommendations for intraoperative transfusion. The existing guidelines were noted to be highly variable in their recommendations and to lack a sufficient evidence base from the intraoperative setting. This represents a major knowledge gap in the literature.

Abstract
Anemia in cancer patients is a relevant condition complicating the course of the neoplastic disease. Overall, we distinguish the anemia which arises under chemotherapy as pure adverse event of the toxic effects of the drugs used, and the anemia induced by the tumour-associated inflammation, oxidative stress, and systemic metabolic changes, which can be worsened by the concomitant anticancer treatments. This more properly cancer-related anemia depends on several overlapping mechanism, including impaired erythropoiesis and functional iron deficiency, which make its treatment more difficult. Standard therapies approved and recommended for cancer anemia, as erythropoiesis-stimulating agents and intravenous iron administration, are limited to the treatment of chemotherapy-induced anemia, preferably in patients with advanced disease, in view of the still unclear effect of erythropoiesis-stimulating agents on tumour progression and survival. Outside the use of chemotherapy, there are no recommendations for the treatment of cancer-related anemia. For a more complete approach, it is fundamentally a careful evaluation of the type of anemia and iron homeostasis, markers of inflammation and changes in energy metabolism. In this way, anemia management in cancer patient would permit a tailored approach that could give major benefits. Experimental drugs targeting hepcidin and activin II receptor pathways are raising great expectations, and future clinical trials will confirm their role as remedies for cancer-related anemia. Recent evidence on the effect of integrated managements, including nutritional support, antioxidants and anti-inflammatory substances, for the treatment of cancer anemia are emerging. In this review article, we show standard, innovative, and experimental treatment used as remedy for anemia in cancer patients.

Abstract
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.

Abstract
Preoperative autologous blood donation (PAD) in bone marrow (BM) donors is performed to meet potential post-harvest transfusion needs and to avoid the risk of allogeneic transfusions. We reviewed retrospectively bone marrow harvests in 216 healthy donors during a ten-year period to determine the use of autologous blood. All donors except four had undergone PAD. The initial hemoglobin level of 153 g/L (male donors) and 135 g/L (female donors), respectively, decreased by about 8 g/L after preoperative blood donation and by 23 g/L after bone marrow harvest (medians). Autologous blood was administered to 70% of donors, 30% of the units remained unused. The evaluation of the risk of reaching transfusion threshold (<115 g/L males, <105 g/L females) revealed that donors with initial hemoglobin above 145 g/L and those weighing above 75 kg have minimal risk of requiring blood substitution (about 10%). A larger volume of bone marrow was obtained from male compared to female donors (1300 vs. 1100 mL) because of their higher body weight, which resulted in a higher number of procured nucleated cells (362 vs. 307 × 106/kg TNC, ns). The donor-recipient weight difference predicted the probability of sufficient collection. Only 1.5% of donors weighing ≥ 20 kg more than recipients failed to reach ≥3 × 108/kg TNC recipient. Our findings affirm previous data that PAD is unnecessary for healthy marrow donors and may be indicated individually after considering the pre-collection hemoglobin level, donor and recipient weight, and expected blood loss. Reasonable substitution cut-offs have to be set together with clinical symptom evaluation. The effective use of PAD also requires an adequate time interval between PAD and BM harvest.

Abstract
BACKGROUND Pre-operative anaemia is associated with adverse outcomes of noncardiac surgery, but its association with myocardial injury after noncardiac surgery (MINS) has not been fully investigated. OBJECTIVE The association between pre-operative anaemia and MINS. DESIGN A single-centre retrospective cohort study. SETTING Tertiary care referral centre. PATIENTS Patients with measured cardiac troponin (cTn) I levels after noncardiac surgery. INTERVENTIONS Patients were separated according to pre-operative anaemia (haemoglobin <13 g dl-1 in men and <12 g dl-1 in women). Anaemia was further stratified into mild and moderate-to-severe at a haemoglobin level threshold of 11 g dl-1. MAIN OUTCOME MEASURES The primary outcome was MINS, defined as a peak cTn I level more than 99th percentile of the upper reference limit within 30 postoperative days. RESULTS Data from a total of 35 170 patients were collected, including 22 062 (62.7%) patients in the normal group and 13 108 (37.3%) in the anaemia group. After propensity score matching, 11919 sets of patients were generated, and the incidence of MINS was significantly associated with anaemia [14.5 vs. 21.0%, odds ratio (OR) 1.57, 95% confidence interval (CI) 1.47 to 1.68, P < 0.001]. For the entire population, multivariable analysis showed a graded association between anaemia severity and MINS (OR 1.32, 95% CI 1.22 to 1.43, P < 0.001 for mild anaemia and OR 1.80, 95% CI 1.66 to 1.94, P < 0.001 for moderate-to-severe anaemia compared with the normal group) and a significantly higher incidence of MINS for moderate-to-severe anaemia than mild anaemia (18.6 vs. 28.6%, OR 1.37, 95% CI 1.25 to 1.50, P < 0.001). The estimated threshold for pre-operative haemoglobin associated with MINS was 12.2 g dl-1, with an area under the curve of 0.622. CONCLUSIONS Pre-operative anaemia was independently associated with MINS, suggesting that MINS may be related to the association between anaemia and postoperative mortality.

Huang H, Cao M. Development and validation of a nomogram to predict intraoperative blood transfusion for gastric cancer surgery. Transfus Med 2021; 31:250-261. [PMID: 33880833 DOI: 10.1111/tme.12777] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Revised: 01/07/2021] [Accepted: 04/08/2021] [Indexed: 01/28/2023]
Abstract
OBJECTIVE To construct and validate a nomogram composed of preoperative variables to predict intraoperative blood transfusion for gastric cancer surgery. BACKGROUND Intraoperative transfusion for gastric cancer surgery is a common medical procedure that is associated with increased postoperative complications. METHODS A total of 999 patients who underwent gastrectomy between January 2010 and June 2019 were randomly allocated into the primary and validation cohorts in a 2:1 ratio. In the primary cohort, logistic analyses were performed to identify independent predictors for transfusion. Using the Akaike information criterion, selected variables were incorporated to construct a nomogram. Validations of the nomogram were performed in the primary and validation cohorts. The discrimination ability of the nomogram was assessed by the concordance index (C-index), and calibration was assessed by calibration curves and the Hosmer-Lemeshow goodness-of-fit test. RESULTS The following risk factors for transfusion were identified and used to construct the nomogram: ASA status (III-IV vs I-II: odds ratio [OR] 1.74), comorbidities (yes vs no: OR 1.57), tumour location (diffuse vs lower: OR 4.05), cTNM stage (III vs I: OR 1.95), and a preoperative haemoglobin level less than 80 g/L (vs over 120 g/L: OR 35.30). The C-index was 0.859 and 0.850 in the primary and validation cohorts, respectively, which both indicated good discrimination of the nomogram. Additionally, both calibration curves and Hosmer-Lemeshow tests (p-value 0.184 and 0.887, respectively) demonstrated high agreement between the predictions and actual outcomes. CONCLUSION A nomogram composed of preoperative variables to predict blood transfusion for gastric cancer surgery was effectively developed and validated. This nomogram could be used to improve the utilisation of red blood cells for gastrectomy.

Abstract
Background Revision knee arthroplasty (RKA) is associated with low hemoglobin (Hb) levels after surgery, which results mostly from perioperative blood loss. Periprosthetic joint infection (PJI) is one of the common reasons for RKA. This study aimed to determine whether low Hb levels affect the healing process of PJI. Methodology This retrospective study included 69 patients who underwent two-stage revision for PJI between 2013 and 2016. Patients were divided into two groups according to the latest Hb levels (Hb < 10 and Hb > 10 g/dL) during hospitalization for the first-stage revision surgery. Laboratory parameters of infection were measured during the cement spacer retention period: C-reactive protein (CRP), sedimentation rate (SEDIM), and white blood cell (WBC) count. Treatment was evaluated in two periods: cement spacer retention period (between the first surgery and second surgery) and the first normal CRP period (between the first surgery with the first normal CRP level during the cement spacer retention period). Infection parameters in the two time periods and reoperation with cement spacer were compared between the groups. Results The mean patient age was 67.3 ± 7.94 (50-87) years, and the female-to-male ratio was 4:1. No difference was found in the postoperative first control CRP, SEDIM, and WBC between the groups (p = 0.953, p = 0.3341, and p = 0.444, respectively). CRP-SEDIM control curves were observed in parallel, and no significant difference was found. The cement spacer retention period was 60.3 ± 24.8 (17-123) days, and the first normal CRP period was 87.3 ± 28.4 (14-161) days; no statistical difference was found between the groups (p = 0.727, p = 0.754). Conclusions In RKA, as low Hb level was not a negative factor of infection, blood transfusion should be avoided as it has many complications.

Abstract
Aim To evaluate possible social and economic benefits of correcting preoperative iron deficiency /iron deficiency anemia as a comorbidity in a model population in the process of transition from the routine practice to the optimized preparation of patients to elective surgery (as exemplified by several circulatory diseases: I20 - I25, class IX ICD 10).Material and methods By building imitation models depending on the patient blood management (PBM) practice, changes in years of life lost/saved adjusted for disability were evaluated, including in monetary terms, in relation to the annual number of operations performed for ischemic heart disease (IHD) (I20 - I25) in the age group of 17 years and older, as well as a potential effect of PBM on the applied health economics.Results With implementation of the PBM systemic measures in cardiac surgery, the potentially prevented annual social and economic damage will amount to more than 38 thousand years of life saved and more than 20.2 billion rubles in monetary terms. Furthermore, it will be possible to exclude 9435 hemotransfusion from the cardiosurgical practice, which will annually save more than 2.3 thousand liters of blood with a total cost of 77.7 million rubles in favor of clinical situations that have no alternative.Conclusion The implementation of PBM in cardiac surgery, the discipline with the highest levels of preoperative iron deficiency/anemia and the use of blood components, will not only improve the clinical outcomes and cost-effectiveness of surgical interventions, but will also prevent social and economic damage to the country.

Abstract
Background The association between allogeneic blood transfusion and healthcare-associated infection (HAI) is considered dose-dependent. However, this association may be confounded by transfusion duration, as prolonged hospitalization stay increases the risk of HAI. Also, it is not clear whether specific blood products have different dose–response risks. Methods In this retrospective cohort study, a logistic regression was used to identify confounding factors, and the association between specific blood products and HAI were analyzed. Then Cox regression and restricted cubic spline regression was used to visualize the hazard of HAI per transfusion product. Results Of 215,338 inpatients observed, 4.16% were transfused with a single component blood product. With regard to these transfused patients, 480 patients (5.36%) developed a HAI during their hospitalization stay. Logistic regression showed that red blood cells (RBCs) transfusion, platelets transfusion and fresh-frozen plasmas (FFPs) transfusion were risk factors for HAI [odds ratio (OR) 1.893, 95% confidence interval (CI) 1.656–2.163; OR 8.903, 95% CI 6.646–11.926 and OR 1.494, 95% CI 1.146–1.949, respectively]. However, restricted cubic spline regression analysis showed that there was no statistically dose–response relationship between different transfusion products and the onset of HAI. Conclusions RBCs transfusion, platelets transfusion and FFPs transfusion were associated with HAI, but there was no dose–response relationship between them.

Abstract
Anaemia is defined by the presence of haemoglobin (Hb) levels < 13 g/dL in men and 12 g/dL in women. Up to 39% of cancer patients present it at the time of diagnosis and up to 40% have iron deficiency. Anaemia causes fatigue, functional deterioration and a reduction in the quality of life; it has also been associated with a poorer response to anti-tumour treatment and lower survival. Basic diagnostic tests for anaemia are simple and should be a routine part of clinical practice. These guidelines review the available evidence on the use of different therapies for treating anaemia: erythropoiesis-stimulating agents, iron supplements, and transfusion of blood products.

Adherence to blood product transfusion guidelines-An observational study of the current transfusion practice in a medical intensive care unit. Transfus Med 2021; 31:227-235.

Abstract
BACKGROUND Blood transfusions though life-saving are not entirely benign. They are the most overused procedure in the hospital and have been under scrutiny by the 'Choosing Wisely campaign'. The strict adoption of restrictive transfusion guidelines could improve patient outcomes while reducing cost. OBJECTIVES In this study, we evaluate adherence to restrictive transfusion guidelines, along with hospital mortality and length of stay (LOS) in transfusion events with a pre-transfusion haemoglobin (Hb) ≥7 g/dl. Additionally, we evaluated associated costs accrued due to unnecessary transfusions. METHODS We conducted a retrospective observational study in a 64-bed medical intensive care unit (MICU) of an academic medical centre involving all adult patients (N = 957) requiring packed red blood cell transfusion between January 2015 and December 2015. RESULTS In total, 3140 units were transfused with a mean pre-transfusion Hb of 6.75 ± 0.86 g/dl. Nine hundred forty-four (30%) transfusion events occurred with a pre-transfusion Hb ≥7 g/dl, and 385 (12.3%) of these occurred in patients without hypotension, tachycardia, use of vasopressors, or coronary artery disease. Forgoing them could have led to a savings of approximately 0.3 million dollars. Transfusion events with pre-transfusion Hb ≥7 g/dl were associated with an increased mortality in patients with acute blood loss (odds ratio [OR] 2.08, 95% confidence interval [CI] 1.11-3.88; p = 0.02) and LOS in patients with chronic blood loss (β1 .8.26, 95% CI 4.09-12.43; p < 0.01). CONCLUSION A subset of anaemic patients in the MICU still receive red blood cell transfusions against restrictive guidelines offering hospitals the potential for effective intervention that has both economic and clinical implications.

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.
