Abstract
In recent years, several safety alerts have questioned or restricted the use of some pharmacological alternatives to allogeneic blood transfusion in established indications. In contrast, there seems to be a promotion of other alternatives, based on blood products and/or antifibrinolytic drugs, which lack a solid scientific basis. The Multidisciplinary Autotransfusion Study Group and the Anemia Working Group España convened a multidisciplinary panel of 23 experts belonging to different healthcare areas in a forum for debate to: 1) analyze the different safety alerts referred to certain transfusion alternatives; 2) study the background leading to such alternatives, the evidence supporting them, and their consequences for everyday clinical practice, and 3) issue a weighted statement on the safety of each questioned transfusion alternative, according to its clinical use. The members of the forum maintained telematics contact for the exchange of information and the distribution of tasks, and a joint meeting was held where the conclusions on each of the items examined were presented and discussed. A first version of the document was drafted, and subjected to 4 rounds of review and updating until consensus was reached (unanimously in most cases). We present the final version of the document, approved by all panel members, and hope it will be useful for our colleagues.

Abstract
BACKGROUND Transfusion thresholds for acute upper gastrointestinal bleeding are controversial. So far, only three small, underpowered studies and one single-centre trial have been done. Findings from the single-centre trial showed reduced mortality with restrictive red blood cell (RBC) transfusion. We aimed to assess whether a multicentre, cluster randomised trial is a feasible method to substantiate or refute this finding. METHODS In this pragmatic, open-label, cluster randomised feasibility trial, done in six university hospitals in the UK, we enrolled all patients aged 18 years or older with new presentations of acute upper gastrointestinal bleeding, irrespective of comorbidity, except for exsanguinating haemorrhage. We randomly assigned hospitals (1:1) with a computer-generated randomisation sequence (random permuted block size of 6, without stratification or matching) to either a restrictive (transfusion when haemoglobin concentration fell below 80 g/L) or liberal (transfusion when haemoglobin concentration fell below 100 g/L) RBC transfusion policy. Neither patients nor investigators were masked to treatment allocation. Feasibility outcomes were recruitment rate, protocol adherence, haemoglobin concentration, RBC exposure, selection bias, and information to guide design and economic evaluation of the phase 3 trial. Main exploratory clinical outcomes were further bleeding and mortality at day 28. We did analyses on all enrolled patients for whom an outcome was available. This trial is registered, ISRCTN85757829 and NCT02105532. FINDINGS Between Sept 3, 2012, and March 1, 2013, we enrolled 936 patients across six hospitals (403 patients in three hospitals with a restrictive policy and 533 patients in three hospitals with a liberal policy). Recruitment rate was significantly higher for the liberal than for the restrictive policy (62% vs 55%; p=0·04). Despite some baseline imbalances, Rockall and Blatchford risk scores were identical between policies. Protocol adherence was 96% (SD 10) in the restrictive policy vs 83% (25) in the liberal policy (difference 14%; 95% CI 7-21; p=0·005). Mean last recorded haemoglobin concentration was 116 (SD 24) g/L for patients on the restrictive policy and 118 (20) g/L for those on the liberal policy (difference -2·0 [95% CI -12·0 to 7·0]; p=0·50). Fewer patients received RBCs on the restrictive policy than on the liberal policy (restrictive policy 133 [33%] vs liberal policy 247 [46%]; difference -12% [95% CI -35 to 11]; p=0·23), with fewer RBC units transfused (mean 1·2 [SD 2·1] vs 1·9 [2·8]; difference -0·7 [-1·6 to 0·3]; p=0·12), although these differences were not significant. We noted no significant difference in clinical outcomes. INTERPRETATION A cluster randomised design led to rapid recruitment, high protocol adherence, separation in degree of anaemia between groups, and non-significant reduction in RBC transfusion in the restrictive policy. A large cluster randomised trial to assess the effectiveness of transfusion strategies for acute upper gastrointestinal bleeding is both feasible and essential before clinical practice guidelines change to recommend restrictive transfusion for all patients with acute upper gastrointestinal bleeding.

Abstract
Variceal bleeding is the most serious complication of portal hypertension. All cirrhotic patients should be screened endoscopically for varices which are present in about 30% of compensated and 60% of decompensated patients at diagnosis. In patients without varices, endoscopy surveillance should be continued every 2 years. Patients with high-risk varices (moderate or large in size, or with red color signs, or in Child-Pugh C patients) should be treated with a nonselective β-blocker to prevent bleeding (propranolol, nadolol or carvedilol). Endoscopic banding ligation is also effective for the prevention of first bleeding, and it is the first choice in patients with contraindications or intolerance to β-blockers. Acute variceal hemorrhage still has a high mortality rate (around 15%) and requires intensive care management and conservative blood transfusion policy. Treatment is based on the combined use of vasoactive drugs, endoscopic band ligation and prophylactic antibiotics. Failures are best managed by transjugular intrahepatic portosystemic shunt (TIPS). Balloon tamponade or specifically designed covered esophageal stents can be used as a bridge to definitive therapy in unstable patients. Early, preemptive TIPS might be the first choice in patients at high risk of failure (Child-Pugh B with active bleeding or Child-Pugh C up to 13 points). Patients surviving a variceal bleeding are at high risk of rebleeding. A combination of β-blockers and endoscopic band ligation is the most effective therapeutic approach. Preliminary data suggest that the addition of simvastatin increases survival in these patients.

Abstract
BACKGROUND AND OBJECTIVES This study aimed to test the safety and efficacy of Hemospray® for emergency control of acute variceal bleeding (AVB) due to portal hypertension in cirrhotic patients. PATIENTS AND METHODS This single-arm, prospective trial, conducted at two hospitals in Belgium and Egypt, included patients admitted to the emergency room with hematemesis and/or melena and known or suspected liver cirrhosis. All patients received urgent hemodynamic stabilization, octreotide (50 mcg bolus then 25 mcg/hour for 24 hours) and intravenous ceftriaxone (1 g/hour). Endoscopy to confirm AVB and Hemospray® application (if indicated) was performed within six hours of admission. Patients were kept under observation for 24 hours and underwent second endoscopy and definitive therapy (band ligation and/or cyanoacrylate injection in cases of gastric varices) the next day. RESULTS Thirty-eight patients were admitted for suspected AVB, and 30 of these had confirmed AVB (70% male; mean age 59.5 years (range, 32.0-73 years)). Child-Pugh class C liver disease was present in 53.4%. Esophageal varices were observed in 83.4% of patients, gastric varices in 10%, and duodenal varices in 6.6%. Spurting bleeding at the time of endoscopy was observed in 43.4%. One patient developed hematemesis six hours after Hemospray® application and underwent emergency endoscopic band ligation. No major adverse events or mortalities were observed during 15-day follow-up. CONCLUSION Hemospray® application was safe and effective at short-term follow-up for emergency treatment of AVB in cirrhotic patients.

Abstract
BACKGROUND AND AIM Visceral fat contributes to insulin resistance and atherosclerosis. We retrospectively investigated whether abdominal fat accumulation, as measured by computed tomography, is a risk of ischemic colitis and related clinical outcomes. MATERIALS AND METHODS Outpatient-onset ischemic colitis patients (n = 58) and age- and sex-matched controls (n = 58) underwent colonoscopy and computed tomography. Associations between body mass index, visceral adipose tissue area, subcutaneous adipose tissue area, and ischemic colitis were estimated using odds ratios adjusted for hypertension, diabetes mellitus, and dyslipidemia. RESULTS In multivariate analysis, ischemic colitis was significantly associated with subcutaneous adipose tissue area (P for trend 0.030) and marginally associated with visceral adipose tissue area (P for trend 0.094), but was not associated with body mass index (P for trend 0.460). The adjusted odds ratios for the highest quartile of subcutaneous and visceral adipose tissue in ischemic colitis were 3.48 (1.06-11.4) and 2.43 (0.74-8.00), respectively, compared with the lowest quartile. When body mass index was considered simultaneously, ischemic colitis remained associated with subcutaneous adipose tissue (P for trend 0.016) and visceral adipose tissue (P for trend 0.077). No significant differences were noted between any of the obesity indices and the distribution type of colitis, blood transfusion requirement, or length of hospital stay. CONCLUSION Abdominal fat accumulation measured by computed tomography, but not body mass index, was associated with outpatient-onset ischemic colitis. Ischemic colitis remained associated with abdominal fat, even when body mass index was simultaneously considered. However, clinical outcomes of ischemic colitis were not associated with abdominal fat accumulation.

Abstract
Nonvariceal upper gastrointestinal bleeding (UGIB) is a major cause of morbidity and mortality worldwide. Mortality from UGIB has remained 5-10% over the past decade. This article presents current evidence-based recommendations for the medical management of UGIB. Preendoscopic management includes initial resuscitation, risk stratification, appropriate use of blood products, and consideration of nasogastric tube insertion, erythromycin, and proton pump inhibitor therapy. The use of postendoscopic intravenous proton pump inhibitors is strongly recommended for certain patient populations. Postendoscopic management also includes the diagnosis and treatment of Helicobacter pylori, appropriate use of proton pump inhibitors and iron replacement therapy.

Abstract
Acute nonvariceal upper gastrointestinal bleeding remains an important cause of hospital admission with an associated mortality of 2-14%. Initial patient evaluation includes rapid hemodynamic assessment, large-bore intravenous catheter insertion and volume resuscitation. A hemoglobin transfusion threshold of 7 g/dL is recommended, and packed red blood cell transfusion may be necessary to restore intravascular volume and improve tissue perfusion. Patients should be risk stratified into low- and high-risk categories, using validated prognostic scoring systems such as the Glasgow-Blatchford, AIMS65 or Rockall scores. Effective early management of acute, nonvariceal upper gastrointestinal hemorrhage is critical for improving patient outcomes.

Abstract
Peptic ulcer bleeding is a common emergency. Management of ulcer bleeding requires prompt risk stratification, initiation of pharmacotherapy, and timely evaluation for endoscopy. Although endoscopy can achieve primary hemostasis in more than 90% of peptic ulcer bleeding, rebleeding may occur in up to 15% of patients after therapeutic endoscopy and is associated with heightened mortality. Early identification of high-risk patients for rebleeding is important. Depending on bleeding severity and center availability, patients with rebleeding may be managed by second endoscopy, transarterial angiographic embolization, or surgery. This article reviews the current management of peptic ulcers with an emphasis on rebleeding.

Abstract
Upper gastrointestinal (UGI) endoscopy is the cornerstone of diagnosis and management of patients presenting with acute UGI bleeding. Once hemodynamically resuscitated, early endoscopy (performed within 24 hours of patient presentation) ensures accurate identification of the bleeding source, facilitates risk stratification based on endoscopic stigmata, and allows endotherapy to be delivered where indicated. Moreover, the preendoscopy use of a prokinetic agent (eg, i.v. erythromycin), especially in patients with a suspected high probability of having blood or clots in the stomach before undergoing endoscopy, may result in improved endoscopic visualization, a higher diagnostic yield, and less need for repeat endoscopy.

Abstract
Acute variceal hemorrhage (AVH) is a lethal complication of portal hypertension and should be suspected in every patient with liver cirrhosis who presents with upper gastrointestinal bleed. AVH-related mortality has decreased in the last few decades from 40% to 15%-20% due to advances in the general and specific management of variceal hemorrhage. This review summarizes current management of AVH and prevention of recurrent hemorrhage with a focus on pharmacologic therapy.

Abstract
As advances in liver disease continue, including the increasing use of liver transplantation, the endoscopist needs to be familiar with the standards of care and potential complications in the management of the cirrhotic population. This includes both elective endoscopic procedures, such as screening colonoscopies and variceal banding, as well as the acutely bleeding cirrhotic patient. Peri-procedural management and standards of care for acute gastrointestinal hemorrhaging of cirrhotic patients will be emphasized. This article will focus on the plethora of data available to highlight the benefits of endoscopic intervention in the care of patients with liver disease and outline the areas of future emphasis.

Abstract
Anemia is the most frequent complication of inflammatory bowel disease (IBD), but anemia, mostly due to iron deficiency, has long been neglected in these patients. The aim was to briefly present the pathophysiology, followed by a balanced overview of the different forms of iron replacement available, and subsequently, to perform a systematic review of studies performed in the last decade on the treatment of iron-deficiency anemia in IBD. Given that intravenous therapies have been introduced in the last decade, a systematic review performed in PubMed, EMBASE, the Cochrane Library, and the websites of WHO, FDA, and EMA covered prospective trials investigating the management of iron-deficiency anemia in IBD published since 2004. A total of 632 articles were reviewed, and 13 articles (2906 patients) with unique content were included. In general, oral supplementation in iron-deficiency anemia should be administered with a target to restore/replenish the iron stores and the hemoglobin level in a suitable way. However, in patients with IBD flares and inadequate responses to or side effects with oral preparations, intravenous iron supplementation is the therapy of choice. Neither oral nor intravenous therapy seems to exacerbate the clinical course of IBD, and intravenous iron therapy can be administered even in active disease stages and concomitantly with biologics. In conclusion, because many physicians are in doubt as to how to manage anemia and iron deficiency in IBD, there is a clear need for the implementation of evidence-based recommendations on this matter. Based on the data presented, oral iron therapy should be preferred for patients with quiescent disease stages and trivial iron deficiency anemia unless such patients are intolerant or have an inadequate response, whereas intravenous iron supplementation may be of advantage in patients with aggravated anemia or flares of IBD because inflammation hampers intestinal absorption of iron.

Abstract
PURPOSE OF REVIEW To discuss the tradeoff between permissive anemia and administering red blood cell transfusion to children in pediatric ICUs. RECENT FINDINGS Postsurgical mortality in adults increases abruptly if their nadir hemoglobin level falls below 5 g/dl. Patients with sepsis, even those in septic shock, and patients with upper gastrointestinal bleeding do not require red blood cell (RBC) transfusion if their hemoglobin level is above 7 g/dl. SUMMARY Anemia is common in critically ill children and is well tolerated most of the time. RBC transfusion is required in cases of hemorrhagic shock and in children with a hemoglobin level below 5 g/dl. Children with sepsis, including septic shock, those with a severe upper gastrointestinal bleeding and all stable critically ill children, including noncyanotic cardiac children older than 28 days, do not require an RBC transfusion if their hemoglobin level is above 7 g/dl. Transfusion threshold in children with univentricular physiology and in critically ill children with a hemoglobin level between 5 and 7 g/dl remains to be determined.

Abstract
PURPOSE Physicians play an important role in strategies to control health care spending. Being aware of the cost of prescriptions is surely the first step to incorporating cost-consciousness into medical practice. The aim of this study was to evaluate current intensivists' knowledge of the costs of common prescriptions and to identify factors influencing the accuracy of cost estimations. METHODS Junior and senior physicians in 99 French intensive care units were asked, by questionnaire, to estimate the true hospital costs of 46 selected prescriptions commonly used in critical care practice. RESULTS With an 83% response rate, 1092 questionnaires were examined, completed by 575 (53%) and 517 (47%) junior and senior intensivists, respectively. Only 315 (29%) of the overall estimates were within 50% of the true cost. Response errors included a 14,756 ± 301 € underestimation, i.e., -58 ± 1% of the total sum (25,595 €). High-cost drugs (>1000 €) were significantly (p < 0.001) the most underestimated prescriptions (-67 ± 1%). Junior grade physicians underestimated more costs than senior physicians (p < 0.001). Using multivariate analysis, junior physicians [odds ratio (OR), 2.1; 95% confidence interval (95% CI), 1.43-3.08; p = 0.0002] and female gender (OR, 1.4; 95% CI, 1.04-1.89; p = 0.02) were both independently associated with incorrect cost estimations. CONCLUSIONS ICU physicians have a poor awareness of prescriptions costs, especially with regards to high-cost drugs. Considerable emphasis and effort are still required to integrate the cost-containment problem into the daily prescriptions in ICUs.

Abstract
Gastric varices (GVs) are known to bleed massively and often difficult to manage with conventional techniques. This article aims to overview the endoscopic methods for the management of acute gastric variceal bleeding, especially the advantages and limits of GV obliteration with tissue adhesives, by comparison with band ligation and other direct endoscopic techniques of approach. The results of indirect radiological and surgical techniques of GV treatment are shortly discussed. A special attention is payed to the emerging role of endoscopic ultrasound in the therapy of bleeding GV, in the confirmation of its eradication and in follow-up strategies.

Abstract
Red blood cell (RBC) transfusion guidelines correctly promote a general restrictive transfusion approach for anemic hospitalized patients. Such recommendations have been derived from evaluation of specific patient populations, and it is important to recognize that engaging a strict guideline approach has the potential to incur harm if the clinician fails to provide a comprehensive review of the patient’s physiological status in determining the benefit and risks of transfusion. We reviewed the data in support of a restrictive or a more liberal RBC transfusion practice, and examined the quality of the datasets and manner of their interpretation to provide better context by which a physician can make a sound decision regarding RBC transfusion therapy. Reviewed studies included PubMed-cited (1974 to 2013) prospective randomized clinical trials, prospective subset analyses of randomized studies, nonrandomized controlled trials, observational case series, consecutive and nonconsecutive case series, and review articles. Prospective randomized clinical trials were acknowledged and emphasized as the best-quality evidence. The results of the analysis support that restrictive RBC transfusion practices appear safe in the hospitalized populations studied, although patients with acute coronary syndromes, traumatic brain injury and patients at risk for brain or spinal cord ischemia were not well represented in the reviewed studies. The lack of quality data regarding the purported adverse effects of RBC transfusion at best suggests that restrictive strategies are no worse than liberal strategies under the studied protocol conditions, and RBC transfusion therapy in the majority of instances represents a marker for greater severity of illness. The conclusion is that in the majority of clinical settings a restrictive RBC transfusion strategy is cost-effective, reduces the risk of adverse events specific to transfusion, and introduces no harm. In anemic patients with ongoing hemorrhage, with risk of significant bleeding, or with concurrent ischemic brain, spinal cord, or myocardium, the optimal hemoglobin transfusion trigger remains unknown. Broad-based adherence to guideline approaches of therapy must respect the individual patient condition as interpreted by comprehensive clinical review.

Abstract
BACKGROUND The long-term impact of transfusions with packed red blood cells (PRBC) among patients undergoing hepatopancreaticobiliary (HPB) surgery remains ill-defined. We sought to determine the impact of overall blood utilization, as well as a restrictive transfusion strategy, on long-term outcomes among patients undergoing an HPB resection for a malignancy. METHODS Data on overall blood utilization and hemoglobin (Hb) levels that triggered a transfusion were obtained for patients with cancer undergoing pancreas or liver surgery between 2009 and 2013. Risk-adjusted recurrence-free (RFS) and overall survival (OS) were assessed based on receipt of PRBC and whether the patient received a transfusion using a restrictive transfusion strategy (intraoperative: Hb <10 g/dL; postoperative: Hb <8 g/dL). RESULTS Four hundred forty-two patients underwent either a pancreas (58.1 %) or liver (41.9 %) resection. Most tumors were pancreatic in origin (41.8 %), while a subset were primary (23.1 %) or secondary (18.8 %) liver tumors. One hundred seventy-five (39.6 %) patients received ≥1 PRBC transfusion either intraoperatively (16.7 %), postoperatively (12.7 %), or both (10.2 %). There was a higher incidence of PRBC transfusion among patients undergoing a pancreas resection, those with higher comorbidities, and those with lower preoperative Hb levels. Perioperative morbidity was higher among patients receiving either 1-2 units (OR 3.14) or 3 or more units of PRBC (OR 8.54). Median OS was 31.9 months. Receipt of a blood transfusion was associated with a worse OS (1-2 units: HR 1.76; 3+units: HR 2.50; both P<0.05), and RFS (3+units: HR 2.91; P=0.02). Utilization of a restrictive transfusion strategy did not impact perioperative morbidity or long-term RFS or OS. CONCLUSIONS Adoption of a more restrictive transfusion strategy in patients undergoing resection for cancer may preserve a limited resource, reduce costs, as well as avoid exposing oncology patients to the unnecessary risks associated with a transfusion.

Abstract
Overt or occult gastrointestinal bleeding is a frequently observed condition in routine gastroenterological practice. Occult gastrointestinal bleeding is usually a purely incidental finding, based on the discovery of iron deficiency anemia in the laboratory or blood in stool (a positive Hemoccult test). However, overt bleeding accompanied by the clinical features of tarry stool, hematemesis, or hematochezia may be a life-threatening condition, calling for immediate emergency management. In contrast to traumatology, algorithms of emergency and intensive medicine are not sufficiently validated yet for acute life-threatening bleeding. The purpose of this review was to present all established and new endoscopic hemostasis techniques and to evaluate their efficacy, as well as to provide the treating endoscopist with practical advice on how he/she could incorporate these procedures into acute medical management. The recommendations are based on inspection of the study results in the recent published literature, as well as emergency medicine algorithms in traumatology.

Abstract
Hypersplenism is a common manifestation of portal hypertension in the cirrhotic. More than half of cirrhotics will have low platelet counts, but neutropenia is much less common. Despite being common in the cirrhotic population, the presence of hypersplenism is of little clinical consequence. The presence of hypersplenism suggests more advanced liver disease and an increase in risk of complications, but there is no data showing that correcting the hypersplenism improves patient survival. In most series, the most common indications for treating the hypersplenism is to increase platelet and white blood cell counts to allow for use of drugs that suppress the bone marrow such as interferon alpha and chemotherapeutic agents. There are several approaches used to treat hypersplenism. Portosystemic shunts are of questionable benefit. Splenectomy, either open or laparoscopically, is the most effective but is associated with a significant risk of portal vein thrombosis. Partial splenic artery embolization and radiofrequency ablation are effective methods for treating hypersplenism, but counts tend to fall back to baseline long-term. Pharmacological agents are also effective in increasing platelet counts. Development of direct acting antivirals against hepatitis C will eliminate the most common indication for treatment. We lack controlled trials designed to determine if treating the hypersplenism has benefits other than raising the platelet and white blood cell counts. In the absence of such studies, hypersplenism in most patients should be considered a laboratory abnormality and not treated, in other words forget it.

Abstract
BACKGROUND The incidence of hip fracture is increasing and it is more common with increasing age. Surgery is used for almost all hip fractures. Blood loss occurs as a consequence of both the fracture and the surgery and thus red blood cell transfusion is frequently used. However, red blood cell transfusion is not without risks. Therefore, it is important to identify the evidence for the effective and safe use of red blood cell transfusion in people with hip fracture. OBJECTIVES To assess the effects (benefits and harms) of red blood cell transfusion in people undergoing surgery for hip fracture. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (31 October 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library, 2014, Issue 10), MEDLINE (January 1946 to 20 November 2014), EMBASE (January 1974 to 20 November 2014), CINAHL (January 1982 to 20 November 2014), British Nursing Index Database (January 1992 to 20 November 2014), the Systematic Review Initiative's Transfusion Evidence Library, PubMed for e-publications, various other databases and ongoing trial registers. SELECTION CRITERIA Randomised controlled trials comparing red blood cell transfusion versus no transfusion or an alternative to transfusion, different transfusion protocols or different transfusion thresholds in people undergoing surgery for hip fracture. DATA COLLECTION AND ANALYSIS Three review authors independently assessed each study's risk of bias and extracted data using a study-specific form. We pooled data where there was homogeneity in the trial comparisons and the timing of outcome measurement. We used GRADE criteria to assess the quality (low, moderate or high) of the evidence for each outcome. MAIN RESULTS We included six trials (2722 participants): all compared two thresholds for red blood cell transfusion: a 'liberal' strategy to maintain a haemoglobin concentration of usually 10 g/dL versus a more 'restrictive' strategy based on symptoms of anaemia or a lower haemoglobin concentration, usually 8 g/dL. The exact nature of the transfusion interventions, types of surgery and participants varied between trials. The mean age of participants ranged from 81 to 87 years and approximately 24% of participants were men. The largest trial enrolled 2016 participants, over 60% of whom had a history of cardiovascular disease. The percentage of participants receiving a red blood cell transfusion ranged from 74% to 100% in the liberal transfusion threshold group and from 11% to 45% in the restrictive transfusion threshold group. There were no results available for the smallest trial (18 participants). All studies were at some risk of bias, in particular performance bias relating to the absence of blinding of personnel. We judged the evidence for all outcomes, except myocardial infarction, was low quality reflecting risk of bias primarily from imbalances in protocol violations in the largest trial and imprecision, often because of insufficient events. Thus, further research is likely to have an important impact on these results.There was no evidence of a difference between a liberal versus restricted threshold transfusion in mortality, at 30 days post hip fracture surgery (risk ratio (RR) 0.92, 95% confidence interval (CI) 0.67 to 1.26; five trials; 2683 participants; low quality evidence) or at 60 days post surgery (RR 1.08, 95% CI 0.80 to 1.44; three trials; 2283 participants; low quality evidence). Assuming an illustrative baseline risk of 50 deaths per 1000 participants in the restricted threshold group at 30 days, these data equate to four fewer (95% CI 17 fewer to 14 more) deaths per 1000 in the liberal threshold group at 30 days.There was no evidence of a difference between a liberal versus restricted threshold transfusion in functional recovery at 60 days, assessed in terms of the inability to walk 10 feet (3 m) without human assistance (RR 1.00, 95% CI 0.87 to 1.15; two trials; 2083 participants; low quality evidence).There was low quality evidence of no difference between the transfusion thresholds in postoperative morbidity for the following complications: thromboembolism (RR 1.15 favouring a restrictive threshold, 95% CI 0.56 to 2.37; four trials; 2416 participants), stroke (RR 2.40 favouring a restrictive threshold, 95% CI 0.85 to 6.79; four trials; 2416 participants), wound infection (RR 1.61 favouring a restrictive threshold, 95% CI 0.77 to 3.35; three trials; 2332 participants), respiratory infection (pneumonia) (RR 1.35 favouring a restrictive threshold, 95% CI 0.95 to 1.92; four trials; 2416 participants) and new diagnosis of congestive heart failure (RR 0.77 favouring a liberal threshold, 95% CI 0.48 to 1.23; three trials; 2332 participants). There was very low quality evidence of a lower risk of myocardial infarction in the liberal compared with the restrictive transfusion threshold group (RR 0.59, 95% CI 0.36 to 0.96; three trials; 2217 participants). Assuming an illustrative baseline risk of myocardial infarction of 24 per 1000 participants in the restricted threshold group, this result was compatible with between one and 15 fewer myocardial infarctions in the liberal threshold group. AUTHORS' CONCLUSIONS We found low quality evidence of no difference in mortality, functional recovery or postoperative morbidity between 'liberal' versus 'restrictive' thresholds for red blood cell transfusion in people undergoing surgery for hip fracture. Although further research may change the estimates of effect, the currently available evidence does not support the use of liberal red blood cell transfusion thresholds based on a 10 g/dL haemoglobin trigger in preference to more restrictive transfusion thresholds based on lower haemoglobin levels or symptoms of anaemia in these people. Future research needs to address the effectiveness of red blood cell transfusions at different time points in the surgical pathway, whether pre-operative, peri-operative or postoperative. In particular, such research would need to consider people who are symptomatic or haemodynamically unstable who were excluded from most of these trials.

Abstract
OBJECT Preoperative anemia may be treated with a blood transfusion. Both are associated with adverse outcomes in various surgical procedures, but this has not been clearly elucidated in surgery for cerebral aneurysms. In this study the authors assessed the association of preoperative anemia and perioperative blood transfusion, separately, on 30-day morbidity and mortality in patients undergoing open surgery for ruptured and unruptured intracranial aneurysms. METHODS The authors identified 668 cases (including 400 unruptured and 268 unruptured intracranial aneurysms) of open surgery for treatment of intracranial aneurysms in the 2006-2012 National Surgical Quality Improvement Program, a validated and reproducible prospective clinical database. Anemia was defined as a hematocrit level less than 39% in males and less than 36% in females. Perioperative transfusion was defined as at least 1 unit of packed or whole red blood cells given at any point between the start of surgery to 72 hours postoperatively. The authors separately compared surgical outcome between patients with (n = 198) versus without (n = 470) anemia, and those who underwent (n = 78) versus those who did not receive (n = 521) a transfusion, using a 1:1 match on propensity score. RESULTS In the matched cohorts, all observed covariates were comparable between anemic (n = 147) versus nonanemic (n = 147) and between transfused (n = 67) versus nontransfused patients (n = 67). Anemia was independently associated with prolonged hospital length of stay (LOS; odds ratio [OR] 2.5, 95% confidence interval [CI] 1.4-4.5), perioperative complications (OR 1.9, 95% CI 1.1-3.1), and return to the operating room (OR 2.1, 95% CI 1.1-4.5). Transfusion was also independently associated with perioperative complications (OR 2.4, 95% CI 1.1-5.3). CONCLUSIONS Preoperative anemia and transfusion are each independent risk factors for perioperative complications in patients undergoing surgery for cerebral aneurysms. Perioperative anemia is also associated with prolonged hospital LOS and 30-day return to the operating room.

Abstract
BACKGROUND Most countries lack a well-coordinated approach to out-of-hours endoscopy. Economic constraints and lack of resources have been identified as important barriers. OBJECTIVE To assess the performance evaluation of an out-of-hours emergency endoscopy model of care. DESIGN During a 3 year period (January 2010 to December 2012), data from consecutive outpatients (n = 332) with non-variceal acute upper gastrointestinal bleeding admitted or transferred to a single referral hospital were prospectively collected. RESULTS 34% (n = 113) were direct admissions whereas 66% (n = 219) were transferred from other hospitals. Median time to upper endoscopy esophagogastroduodenoscopy (EGD) was 6 h and 7.7 h for direct admissions and transferred, respectively. EGD was performed within 24 h in 90% of the patients. Rebleeding, in-hospital mortality, 30 day mortality and need for surgery were respectively 9.8%, 5.8%, 7.4%, and 6.6% and were not significantly different between the two groups. Age, malignancy, and moderate to high clinical Rockall risk score were independent predictors of in-hospital mortality in both groups. Age remained as an important predictor of main outcomes in transferred patients, while comorbidities differed according to admission status and predictable outcomes. CONCLUSION This gastroenterology emergency model improved access and equity to out-of-hours endoscopy in an effective, safe, and timely way, recognized by the rates and the homogeneity observed in the outcomes, between transferred patients and direct admissions.

Abstract
BACKGROUND Blood transfusion might affect long-term mortality by changing immune function and thus potentially increasing the risk of subsequent infections and cancer recurrence. Compared with a restrictive transfusion strategy, a more liberal strategy could reduce cardiac complications by lowering myocardial damage, thereby reducing future deaths from cardiovascular disease. We aimed to establish the effect of a liberal transfusion strategy on long-term survival compared with a restrictive transfusion strategy. METHODS In the randomised controlled FOCUS trial, adult patients aged 50 years and older, with a history of or risk factors for cardiovascular disease, and with postoperative haemoglobin concentrations lower than 100 g/L within 3 days of surgery to repair a hip fracture, were eligible for enrolment. Patients were recruited from 47 participating hospitals in the USA and Canada, and eligible participants were randomly allocated in a 1:1 ratio by a central telephone system to either liberal transfusion in which they received blood transfusion to maintain haemoglobin level at 100 g/L or higher, or restrictive transfusion in which they received blood transfusion when haemoglobin level was lower than 80 g/L or if they had symptoms of anaemia. In this study, we analysed the long-term mortality of patients assigned to the two transfusion strategies, which was a secondary outcome of the FOCUS trial. Long-term mortality was established by linking the study participants to national death registries in the USA and Canada. Treatment assignment was not masked, but investigators who ascertained mortality and cause of death were masked to group assignment. Analyses were by intention to treat. The FOCUS trial is registered with ClinicalTrials.gov, number NCT00071032. FINDINGS Between July 19, 2004, and Feb 28, 2009, 2016 patients were enrolled and randomly assigned to the two treatment groups: 1007 to the liberal transfusion strategy and 1009 to the restrictive transfusion strategy. The median duration of follow-up was 3·1 years (IQR 2·4-4·1 years), during which 841 (42%) patients died. Long-term mortality did not differ significantly between the liberal transfusion strategy (432 deaths) and the restrictive transfusion strategy (409 deaths) (hazard ratio 1·09 [95% CI 0·95-1·25]; p=0·21). INTERPRETATION Liberal blood transfusion did not affect mortality compared with a restrictive transfusion strategy in a high-risk group of elderly patients with underlying cardiovascular disease or risk factors. The underlying causes of death did not differ between the trial groups. These findings do not support hypotheses that blood transfusion leads to long-term immunosuppression that is severe enough to affect long-term mortality rate by more than 20-25% or cause of death.

Abstract
UNLABELLED Liberal versus restrictive red blood cell (RBC) transfusion triggers have been debated for years. This review illustrates the human body's physiologic response to acute anemia and summarizes the evidence from prospective randomized trials (RCTs) for restrictive use of RBC transfusions in high-risk patients. During progressive anemia, the human body maintains the oxygen delivery to the tissues by an increase in cardiac output and peripheral oxygen extraction. Seven RCTs with a total of 5,566 high-risk patients compared a restrictive hemoglobin (Hb) transfusion trigger (Hb < 70 or < 80 g/l) with a liberal Hb transfusion trigger (Hb < 90 or < 100 g/l). Unanimously these studies show non-inferiority, safety, and a significant reduction in RBC transfusions in the restrictive groups. In one RCT mortality was higher in the liberal Hb transfusion group, and in two additional RCTs mortality of subgroups or after risk adjustment was significantly higher in the liberal Hb transfusion trigger groups. CONCLUSION Strong RCT evidence suggests the safety of restrictive transfusion triggers. As a consequence, an Hb transfusion trigger of <70 g/l is recommended for high risk patients.

Abstract
OBJECTIVE To compare the benefit and harm of restrictive versus liberal transfusion strategies to guide red blood cell transfusions. DESIGN Systematic review with meta-analyses and trial sequential analyses of randomised clinical trials. DATA SOURCES Cochrane central register of controlled trials, SilverPlatter Medline (1950 to date), SilverPlatter Embase (1980 to date), and Science Citation Index Expanded (1900 to present). Reference lists of identified trials and other systematic reviews were assessed, and authors and experts in transfusion were contacted to identify additional trials. TRIAL SELECTION Published and unpublished randomised clinical trials that evaluated a restrictive compared with a liberal transfusion strategy in adults or children, irrespective of language, blinding procedure, publication status, or sample size. DATA EXTRACTION Two authors independently screened titles and abstracts of trials identified, and relevant trials were evaluated in full text for eligibility. Two reviewers then independently extracted data on methods, interventions, outcomes, and risk of bias from included trials. random effects models were used to estimate risk ratios and mean differences with 95% confidence intervals. RESULTS 31 trials totalling 9813 randomised patients were included. The proportion of patients receiving red blood cells (relative risk 0.54, 95% confidence interval 0.47 to 0.63, 8923 patients, 24 trials) and the number of red blood cell units transfused (mean difference -1.43, 95% confidence interval -2.01 to -0.86) were lower with the restrictive compared with liberal transfusion strategies. Restrictive compared with liberal transfusion strategies were not associated with risk of death (0.86, 0.74 to 1.01, 5707 patients, nine lower risk of bias trials), overall morbidity (0.98, 0.85 to 1.12, 4517 patients, six lower risk of bias trials), or fatal or non-fatal myocardial infarction (1.28, 0.66 to 2.49, 4730 patients, seven lower risk of bias trials). Results were not affected by the inclusion of trials with unclear or high risk of bias. Using trial sequential analyses on mortality and myocardial infarction, the required information size was not reached, but a 15% relative risk reduction or increase in overall morbidity with restrictive transfusion strategies could be excluded. CONCLUSIONS Compared with liberal strategies, restrictive transfusion strategies were associated with a reduction in the number of red blood cell units transfused and number of patients being transfused, but mortality, overall morbidity, and myocardial infarction seemed to be unaltered. Restrictive transfusion strategies are safe in most clinical settings. Liberal transfusion strategies have not been shown to convey any benefit to patients.

Abstract
BACKGROUND Whether a restrictive threshold for hemoglobin level in red-cell transfusions, as compared with a liberal threshold, reduces postoperative morbidity and health care costs after cardiac surgery is uncertain. METHODS We conducted a multicenter, parallel-group trial in which patients older than 16 years of age who were undergoing nonemergency cardiac surgery were recruited from 17 centers in the United Kingdom. Patients with a postoperative hemoglobin level of less than 9 g per deciliter were randomly assigned to a restrictive transfusion threshold (hemoglobin level <7.5 g per deciliter) or a liberal transfusion threshold (hemoglobin level <9 g per deciliter). The primary outcome was a serious infection (sepsis or wound infection) or an ischemic event (permanent stroke [confirmation on brain imaging and deficit in motor, sensory, or coordination functions], myocardial infarction, infarction of the gut, or acute kidney injury) within 3 months after randomization. Health care costs, excluding the index surgery, were estimated from the day of surgery to 3 months after surgery. RESULTS A total of 2007 patients underwent randomization; 4 participants withdrew, leaving 1000 in the restrictive-threshold group and 1003 in the liberal-threshold group. Transfusion rates after randomization were 53.4% and 92.2% in the two groups, respectively. The primary outcome occurred in 35.1% of the patients in the restrictive-threshold group and 33.0% of the patients in the liberal-threshold group (odds ratio, 1.11; 95% confidence interval [CI], 0.91 to 1.34; P=0.30); there was no indication of heterogeneity according to subgroup. There were more deaths in the restrictive-threshold group than in the liberal-threshold group (4.2% vs. 2.6%; hazard ratio, 1.64; 95% CI, 1.00 to 2.67; P=0.045). Serious postoperative complications, excluding primary-outcome events, occurred in 35.7% of participants in the restrictive-threshold group and 34.2% of participants in the liberal-threshold group. Total costs did not differ significantly between the groups. CONCLUSIONS A restrictive transfusion threshold after cardiac surgery was not superior to a liberal threshold with respect to morbidity or health care costs.

Utilisation of Blood Components in Trauma Surgery: A Single-Centre, Retrospective Analysis before and after the Implementation of an Educative PBM Initiative. Transfus Med Hemother 2015; 42:83-9.

Abstract
BACKGROUND The aim of our single-centre retrospective study presented here is to further analyse the utilisation of allogeneic blood components within a 5-year observation period (2009-2013) in trauma surgery (15,457 patients) under the measures of an educational patient blood management (PBM) initiative. METHODS After the implementation of the PBM initiative in January 2012, the Institute of Transfusion Medicine und Transplantation Immunology educates surgeons and nurses at the Department of Trauma Surgery to avoid unnecessary blood transfusions. A standardised reporting system was used to document the utilisation of blood components carefully for the most frequent diagnoses and surgical interventions in trauma surgery. These measures served as basis for the implementation of an interdisciplinary systematic exchange of information to foster decision-making processes in favour of patient blood management. RESULTS Since January 2012, the proportion of patients who received a transfusion as well as the number of transfused red blood cell (RBC) (7.3%/6.4%; p = 0.02), fresh frozen plasma (FFP) (1.7%/1.3%; p < 0.05) and platelet (PLT) (1.0%/0.5%; p < 0.001) units were reduced as a result of our PBM initiative. However, among the transfused patients, the number of administered RBC, FFP and PLT units did not decrease significantly. Overall, patients who did not receive transfusions were younger than transfused patients (p = 0.001). The subgroup with the highest probability of blood transfusion administered included patients with intensive care and long-term ventilation (before/after implementation of PBM: RBC 81.5%/75.9%; FFP 33.3%/20.4%; PLT 24.1%/13.0%). Only a total of 60 patients of 531 patients suffering multiple traumas were massively transfused (before/after implementation of PBM: RBC 55.6%/49.8%; FFP 28.4%/20.4%; PLT 17.6%/8.9%). CONCLUSION According to our educational PBM initiative, at least the proportion of trauma patients who received allogeneic blood transfusions could be reduced significantly. However, in case of blood transfusions, the total consumption of RBC, FFP and PLT units remained stable in both time periods. This phenomenon might indicate that the actual need of blood transfusions rather depends on the severity of trauma-related blood loss, the coagulopathy rates or the complexity of the surgical intervention which mainly determines the intra-operative blood loss. Taken together, educational training sessions and systematic reporting systems are suitable measures to avoid unnecessary allogeneic blood transfusions and to continuously improve their restrictive application.

Abstract
BACKGROUND Red blood cell transfusions (RBCTs) are associated with cancer recurrence following resection of colorectal cancer. Their impact after colorectal liver metastases (CRLM) resection remains debated. We sought to explore the association between perioperative RBCT and oncologic outcomes following resection of CRLM. METHODS We reviewed patients undergoing partial hepatectomy for CRLM from 2003 to 2012 at a single institution. Date of death was abstracted from a validated population-based cancer registry. Primary outcome was overall survival (OS). Secondary outcome was recurrence-free survival (RFS). Survivals were estimated using Kaplan-Meier methods and compared with log-rank test based on transfusion status. Cox regression analysis examined the association of RBCT with OS and RFS, while adjusting for age, preoperative chemotherapy, Clinical Risk Score, and period of treatment (2003-2007 vs. 2008-2012). RESULTS Among 483 patients, 27.5 % received RBCT. Ninety-day postoperative mortality was 4.8 %. At median follow-up of 33 (interquartile range 20.1-54.8) months, 5-year OS was inferior in transfused patients (45.9 vs. 61.0 %; p < 0.0001). Five-year RFS was decreased with RBCT (15.5 vs. 31.6 %; p < 0.0001). The difference persisted when considering only 90-day survivors for 5-year OS (53.1 vs. 61.9 %, p = 0.023) and RFS (15.6 vs. 31.6 %; p < 0.0001). After adjustment for prognostic factors, RBCT was independently associated with decreased OS (hazard ratio 2.24; 95 % confidence interval 1.60-3.15) and RFS (hazard ratio 1.71; 95 % confidence interval 1.28-2.28). CONCLUSIONS Perioperative RBCT is independently associated with decreased OS and RFS following hepatectomy for CRLM. Interventions to minimize and rationalize the use of RBCT for hepatectomy are warranted to mitigate this detrimental effect on long-term outcomes.

[PMID: 25866731 PMCID: PMC4391998 DOI: 10.5223/pghn.2015.18.1.30] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2014] [Revised: 12/23/2014] [Accepted: 01/13/2015] [Indexed: 12/02/2022] Open
Abstract
PURPOSE The aims of our study were to evaluate the blood urea nitrogen to creatinine ratio (BUN/Cr ratio) for distinguishing between an upper and lower gastrointestinal bleeding (GIB), and differentiating between the two most common causes of upper gastrointestinal bleeding (UGIB) presenting with melena in children. METHODS Retrospective data of patients with GIB presenting with melena were analyzed. The data from 60 cases were reviewed including demographics, laboratory findings, diagnostic modalities and results, treatments, and transfusions. RESULTS Among the 60 cases, UGIB and lower gastrointestinal bleeding (LGIB) were found in 35 cases (58.3%) and 14 cases (23.3%), respectively. The two common causes of UGIB were varices (37.1%), and peptic ulcer diseases (PUD) (31.4%). The BUN/Cr ratio of 30 or greater was higher in UGIB than LGIB (odds ratio [OR], 6.9; 95% confidence interval [95% CI], 1.3-37.2). In UGIB, the BUN/Cr ratio of the varices group was higher than that of the PUD group (p=0.015). The OR for the BUN/Cr ratio appeared as 1.2 per unit increase in the varices group than the PUD group (95% CI, 1.03-1.3). There was no difference between the PUD group and Meckel's diverticulum group. CONCLUSION The BUN/Cr ratio was not uneven in differentiating UGIB from LGIB of children with melena in our study. This suggests that BUN/Cr ratio should be interpreted carefully.

Longer RBC storage duration is associated with increased postoperative infections in pediatric cardiac surgery. Pediatr Crit Care Med 2015; 16:227-35.

Abstract
OBJECTIVES Infants and children undergoing open heart surgery routinely require multiple RBC transfusions. Children receiving greater numbers of RBC transfusions have increased postoperative complications and mortality. Longer RBC storage age is also associated with increased morbidity and mortality in critically ill children. Whether the association of increased transfusions and worse outcomes can be ameliorated by use of fresh RBCs in pediatric cardiac surgery for congenital heart disease is unknown. INTERVENTIONS One hundred and twenty-eight consecutively transfused children undergoing repair or palliation of congenital heart disease with cardiopulmonary bypass who were participating in a randomized trial of washed versus standard RBC transfusions were evaluated for an association of RBC storage age and clinical outcomes. To avoid confounding with dose of transfusions and timing of infection versus timing of transfusion, a subgroup analysis of patients only transfused 1-2 units on the day of surgery was performed. MEASUREMENTS AND MAIN RESULTS Mortality was low (4.9%) with no association between RBC storage duration and survival. The postoperative infection rate was significantly higher in children receiving the oldest blood (25-38 d) compared with those receiving the freshest RBCs (7-15 d) (34% vs 7%; p = 0.004). Subgroup analysis of subjects receiving only 1-2 RBC transfusions on the day of surgery (n = 74) also demonstrates a greater prevalence of infections in subjects receiving the oldest RBC units (0/33 [0%] with 7- to 15-day storage; 1/21 [5%] with 16- to 24-day storage; and 4/20 [20%] with 25- to 38-day storage; p = 0.01). In multivariate analysis, RBC storage age and corticosteroid administration were the only predictors of postoperative infection. Washing the oldest RBCs (> 27 d) was associated with a higher infection rate and increased morbidity compared with unwashed RBCs. DISCUSSION Longer RBC storage duration was associated with increased postoperative nosocomial infections. This association may be secondary in part, to the large doses of stored RBCs transfused, from single-donor units. Washing the oldest RBCs was associated with increased morbidity, possibly from increased destruction of older, more fragile erythrocytes incurred by washing procedures. Additional studies examining the effect of RBC storage age on postoperative infection rate in pediatric cardiac surgery are warranted.

Abstract
Cardiogenic shock (CS) remains the most common cause of death in patients with acute myocardial infarction although mortality could be reduced from formerly ∼80% to 40-50%. In addition to percutaneous coronary intervention or coronary artery bypass grafting, catecholamines, fluids, intraaortic balloon pumping (IABP), and also active assist devices are widely used for CS management. However, there is only limited evidence for any of the above treatments except for early revascularization and the relative ineffectiveness of IABP. This updated review will therefore outline the management of CS complicating acute myocardial infarction with major focus on evidence-based revascularization techniques, intensive care unit treatment including ventilation, transfusion regimens, adjunctive medication, and mechanical support devices.

Abstract
GOALS The Institute for Patient Blood Management and Bloodless Medicine at the Englewood Hospital has considerable experience in managing patients with gastrointestinal bleeding who do not accept blood-derived products. We present our data and experience over the last 8 years in managing such patients. BACKGROUND There is paucity of data on management and outcomes of gastrointestinal bleeding in patients who do not accept blood-derived products. STUDY We performed a retrospective study of patients from 2003 to 2011 presenting with gastrointestinal bleeding who do not accept blood-derived products. Inclusion criteria were either overt bleeding with a presenting hemoglobin (Hb) of <12 g/dL or a decrease in Hb of >1.5 g/dL. RESULTS Ninety-six patients who met the inclusion criteria were included. Forty-one upper and 48 lower gastrointestinal bleeding sources were identified. Mean Hb was 8.8 g/dL and mean nadir was 6.9 g/dL. Among 37 patients (80.5%) with Hb ≤6.0 g/dL, 30 (81%) survived. Four of 7 patients (57%) with a Hb <3 g/dL survived. The overall mortality rate was 10.4%. In unadjusted logistic regression models, age [1.06 (1.01-1.12 y)], admission to ICU [6.37(1.27-31.9)], and anticoagulation use [6.95 (1.57-30.6)] were associated with increased mortality. Initial Hb [0.68 (0.51-0.92)] and nadir Hb [0.48 (0.29-0.78)] inversely predicted mortality. CONCLUSIONS These results suggest that transfusion-free management of gastrointestinal hemorrhage can be effective with mortality comparable with the general population accepting medically indicated transfusion. Management of these patients is challenging and requires a dedicated multidisciplinary team approach knowledgeable in techniques of blood conservation.

Abstract
UNLABELLED The criteria for defining failure to control bleeding in cirrhosis patients were introduced at the Baveno II/III meetings and were widely used as endpoints in clinical trials. Because they lacked specificity, the Baveno IV criteria were proposed in 2005 and slightly modified in 2010 (Baveno V). These criteria included a new index for patients undergoing transfusion, called adjusted-blood-requirement-index (ABRI=number of blood units/(final-initial hematocrit+0.01)), with a cutoff value of 0.75. In this multicenter prospective study, we sought to 1) validate the Baveno IV/V criteria; 2) compare them to the Baveno II/III criteria; 3) assess ABRI performance using a standardized calculation. The key inclusion criteria were: 1) variceal bleeding; 2) cirrhosis; 3) no need to modify the transfusion policy. The patients were classified according to the Baveno IV, V, and II/III criteria. The gold standard for failure during a 5-day period was the clinical judgment of three independent experts, blinded to the Baveno assessments. A total of 249 patients were included. The experts' agreement in clinical judgment of the failure was 80%. Failure occurred in 20.5% of patients; the c-statistics were 0.72 versus 0.64 and 0.65 for Baveno IV versus Baveno II/III and Baveno V criteria (P=0.001 for both). ABRI did not improve the diagnostic performance of the Baveno IV criteria. The Baveno IV, but not Baveno II/III, criteria independently predicted survival. CONCLUSION The Baveno IV criteria demonstrated a higher accuracy than the Baveno II/III and Baveno V criteria for assessing failure to control bleeding and predicted survival independently. Together, our results show that ABRI is not a useful metric, and the Baveno IV criteria should replace the Baveno II/III criteria.

Abstract
Objective: The objective of this report is to review the physiology and management of anemia in critical care. Selected publications on physiology and transfusion related to anemia and critical care, including the modern randomized trials of conservative versus liberal transfusion policy, were used. Anemia is compensated and tolerated in most critically ill patients as long as oxygen delivery is at least twice oxygen consumption. There are risks to blood transfusion which can be minimized by blood banking practice. The availability of cultured red cells may allow correction of anemia without significant risk. The benefit of transfusion in anemia must be weighted against the risk in any specific patient. Conclusion and Recommendation: In a criticially ill patient, anemia should be managed to avoid oxygen supply dependency (oxygen delivery less than twice comsumption) and to maintain moderate oxygen delivery reserve (DO2/VO2 > 3).

Transfusions for anemia in adult and pediatric patients with malignancies. Blood Rev 2015; 29:291-9.

Abstract
Anemia is present in over two-thirds of patients with malignant hematological disorders. The etiology of anemia predominates from ineffective erythropoiesis from marrow infiltration, cytokine related suppression, erythropoietin suppression, and vitamin deficiency; ineffective erythropoiesis is further exacerbated by accelerated clearance due to antibody mediated hemolysis and thrombotic microangiopathy. As the anemia is chronic in nature, symptoms are generally well tolerated and often non-specific. Transfusion of red blood cells (RBCs) is a balance between providing benefit for patients while avoiding risks of transfusion. Conservative/restrictive RBC transfusion practices have shown equivalent patient outcomes compared to liberal transfusion practices, and meta-analysis has shown improved in-hospital mortality, reduced cardiac events, re-bleeding, and bacterial infections. The implications for a lower threshold for transfusion in patients with malignancies are therefore increasingly being scrutinized. Alternative management strategies for anemia with IV iron and erythropoietin stimulating agents (ESAs) should be considered in the appropriate settings.

Transfusion interventions in critical bleeding requiring massive transfusion: a systematic review. Transfus Med Rev 2015; 29:127-37.

Abstract
Critical bleeding (CB) requiring massive transfusion (MT) can occur in a variety of clinical contexts and is associated with substantial mortality and morbidity. In 2011, the Australian National Blood Authority (NBA) published patient blood management guidelines for CB and MT, which found limited high-quality evidence from which only 2 recommendations could be made. The aim of this systematic review (SR) was to update these guidelines and identify evidence gaps still to be addressed. A comprehensive search was performed for randomized controlled trials (RCTs) and SRs using MeSH index and free text terms in MEDLINE, the Cochrane Library (Issue 11, 2012), EMBASE, CINHAL, PUBMED, and the Transfusion Evidence Library up to July 15, 2014. The evidence was grouped according to 4 questions based on the original guideline relating to transfusion interventions: (1) effect of dose, timing, and ratio of red blood cells (RBCs) to component therapy on patient outcomes; (2) effect of RBC transfusion on patient outcomes; (3) effect of fresh frozen plasma, platelet, cryoprecipitate, fibrinogen concentrate, and prothrombin complex concentrate on patient outcomes; and (4) effect of recombinant activated factor VII (rFVIIa) on patient outcomes. From this search, 19 studies were identified: 6 RCTs and 13 SRs. Two of the RCTs were pilot/feasibility studies, 3 were investigating rFVIIa, and 1 compared restrictive versus liberal RBC transfusion in upper gastrointestinal hemorrhage. Overall, limited new evidence was identified and substantial evidence gaps remain, particularly with regard to the effect of component therapies, including ratio of RBC to component therapies, on patient outcomes. Clinical trials to address these questions are required.
