Background Anemia is frequent among patients with traumatic brain injury (TBI) and is associated with an increased risk of poor outcome. The optimal hemoglobin concentration to trigger red blood cell (RBC) transfusion in patients with TBI is not clearly defined. Methods All eligible consecutive adult patients admitted to the intensive care unit (ICU) with moderate or severe TBI were randomized to a “restrictive” (hemoglobin transfusion threshold of 7 g/dL), or a “liberal” (threshold 9 g/dL) transfusion strategy. The transfusion strategy was continued for up to 14 days or until ICU discharge. The primary outcome was the mean difference in hemoglobin between groups. Secondary outcomes included transfusion requirements, intracranial pressure management, cerebral hemodynamics, length of stay, mortality and 6-month neurological outcome. Results A total of 44 patients were randomized, 21 patients to the liberal group and 23 to the restrictive group. There were no baseline differences between the groups. The mean hemoglobin concentrations during the 14-day period were 8.4 ± 1.0 and 9.3 ± 1.3 ( p  < 0.01) in the restrictive and liberal groups, respectively. Fewer RBC units were administered in the restrictive than in the liberal group (35 vs. 66, p  = 0.02). There was negative correlation ( r  = − 0.265, p  < 0.01) between hemoglobin concentration and middle cerebral artery flow velocity as evaluated by transcranial Doppler ultrasound and the incidence of post-traumatic vasospasm was significantly lower in the liberal strategy group (4/21, 3% vs. 15/23, 65%; p  < 0.01). Hospital mortality was higher in the restrictive than in the liberal group (7/23 vs. 1/21; p  = 0.048) and the liberal group tended to have a better neurological status at 6 months ( p  = 0.06). Conclusions The trial reached feasibility criteria. The restrictive group had lower hemoglobin concentrations and received fewer RBC transfusions. Hospital mortality was lower and neurological status at 6 months favored the liberal group. Trial registration ClinicalTrials.gov, NCT02203292 . Registered on 29 July 2014.

The establishment of systems to ensure that all donated blood is screened for transfusion-transmissible infections is a core component of every national blood program. Globally, however, there are significant variations in the extent to which donated blood is screened, the screening strategies adopted and the overall quality and effectiveness of the blood screening process. As a result, in many countries the recipients of blood and blood products remain at unacceptable risk of acquiring life-threatening infections that could easily be prevented.These recommendations are designed to support countries in establishing effective national programs to ensure 100% quality-assured screening of donated blood for transfusion-transmissible infections. In countries where systems are not yet fully in place, the recommendations will be helpful in instituting a step-wise process to implement them.

* Hemovigilance is a \"quality process\" which aims to improve quality and increase safety of blood transfusion, by surveying all activities of the blood transfusion chain, from donors to recipients.Hemovigilance programmes have now been in existence for over 15 years, but many countries and centers are still at the development stage.

In modern blood banking, quality control of blood products ensures the timely availability of a blood component of high-quality yield with maximum efficacy and minimal risk to potential recipients. A prospective cross-sectional study was carried out at Mansoura University Hospital Blood Bank (MUHBB) aiming to assess the internal quality control (IQC) of 300 units of each blood components, red blood cell concentrates (RBCs), fresh frozen plasma (FFP), and platelet concentrates (PCs), and to explore their compliance with The Egyptian National Blood Transfusion Services (NBTS ),The American Association of Blood Banks (AABB), and Council of Europe (CE) standard criteria. IQC of different blood products was accepted if > 90% of units were fulfilled the standard requirements. The results of our study show that the total compliance of RBCs was 93.3% according to NBTS and CE standards and 96% as regards AABB standards. The total compliance of FFP was 94.0% according to NBTS and CE standards and 96.0% as regards AABB standards. While the total compliance of PCs was 96.0% according to NBTS and AABB standards and 93.3% as regards CE standards. Continuous improvement is recommended to decrease the percentage of noncompliance in the QC parameters included in our study and to uplift the blood transfusion practices.

Auditing and feedback are frequently used to improve patient care. However, it remains unclear how to optimize feedback effectiveness for the appropriate use of treatments such as blood transfusion, a common but costly procedure that is more often overused than underused. To evaluate 2 theoretically informed feedback interventions to improve the appropriate use of blood transfusions. Two sequential, linked 2 × 2 cluster randomized trials were performed in hospitals in the UK participating in national audits of transfusion for perioperative anemia and management of hematological disorders. Data were collected for a surgical trial from October 1, 2014, to October 31, 2016, with follow-up completed on October 31, 2016. Data were collected for a hematological trial through follow-up from July 1, 2015, to June 30, 2017. Trial data were analyzed from November 1, 2016, to June 1, 2019. Hospitals were randomized to standard content or enhanced content to improve feedback clarity and usability and to standard support or enhanced support for staff to act on feedback. The primary end point was appropriateness of transfusions audited at 12 months. Secondary end points included volume of transfusions (aiming for reductions at patient and cluster levels) and transfusion-related adverse events and reactions. One hundred thirty-five of 152 eligible clusters participated in the surgical audit (2714 patients; mean [SD] age, 74.9 [14.0] years; 1809 women [66.7%]), and 134 of 141 participated in the hematological audit (4439 patients; median age, 72.0 [IQR, 64.0-80.0] years; 2641 men [59.5%]). Fifty-seven of 69 clusters (82.6%) in the surgical audit randomized to enhanced content downloaded reports compared with 52 of 66 clusters (78.8%) randomized to standard reports. Fifty-nine of 68 clusters (86.8%) randomized to enhanced support logged onto the toolkit. The proportion of patients with appropriate transfusions was 0.184 for standard content and 0.176 for enhanced content (adjusted odds ratio [OR], 0.91 [97.5% CI, 0.61-1.36]) and 0.181 for standard support and 0.180 for enhanced support (adjusted OR, 1.05 [97.5% CI, 0.68-1.61]). For the hematological audit, 53 of 66 clusters (80.3%) randomized to enhanced content downloaded the reports compared with 53 of 68 clusters (77.9%) randomized to standard content. Forty-nine of 67 clusters sites (73.1%) assigned to enhanced support logged into the toolkit at least once. The proportion of patients with appropriate transfusions was 0.744 for standard content and 0.714 for enhanced content (adjusted OR, 0.81 [97.5% CI, 0.56-1.12]), and 0.739 for standard support and 0.721 for enhanced support (adjusted OR, 0.96 [97.5% CI, 0.67-1.38]). This comparison of cluster randomized trials found that interventions to improve feedback usability and guide local action were no more effective than standard feedback in increasing the appropriate use of blood transfusions. Auditing and feedback delivered at scale is a complex and costly program; therefore, effective responses may depend on developing robust local quality improvement arrangements, which can be evaluated using rigorous experimental designs embedded within national programs. isrctn.org Identifier: ISRCTN15490813.

Objective To describe the relationship between clinical practice and national guidelines for the transfusion of red blood cells (RBCs), fresh frozen plasma (FFP), platelets, and cryoprecipitate in Australian and New Zealand intensive care units (ICUs). Setting Forty-seven ICUs over a 5-week period from August to September 2008. Design Prospective, observational, multicentre, cohort study. Patients A total of 874 patients receiving any type of blood transfusion. Methods All patients who were transfused at least one unit of any blood component were included. Patient-specific and blood-component specific data were gathered. Pre-transfusion haemoglobin, platelet count, international normalised ratio (INR), and fibrinogen levels were compared to national guidelines. Results Of all 874 patients, 757 received RBCs (86.6%), 231 (26.4%) received platelets, 340 (38.9%) received FFP, and 78 (8.9%) received cryoprecipitate. Bleeding was the reason for administration of RBCs in 46%, FFP in 55%, and platelets in 47% of transfusions. The mean (SD) pre-transfusion haemoglobin was 77.6 (9.5) g/l, while the geometric means (95% CI) for platelet count, INR, and fibrinogen were 67.0 (59.7–75.3) × 10 9 /l, 1.84 (1.76–1.93), and 1.4 (1.1–1.8) g/l, respectively. The proportions of transfusions not adherent to guidelines were 2% for RBC, but 53% for platelets, 29% for FFP, and 88% for cryoprecipitate (RBC vs. other transfusion p  < 0.001 for all). Conclusions Transfusion practice of RBCs in Australian and New Zealand ICUs is restrictive and is concordant with guidelines. However, the transfusion of other blood components is not.

Blood transfusion is one of the most common procedures in patients in hospital so it is imperative that clinicians are knowledgeable about appropriate blood product administration, as well as the signs, symptoms, and management of transfusion reactions. In this Review, we, an international panel, provide a synopsis of the pathophysiology, treatment, and management of each diagnostic category of transfusion reaction using evidence-based recommendations whenever available.

Background Since 2008, updated perioperative blood management (PoBM) guidelines have been implemented in Zhejiang, China. These guidelines ensure that the limited blood resources meet increasing clinical needs and patient safety requirements. We assessed the effects of implementing updated PoBM guidelines in hospitals in Zhejiang, China. Methods We performed a retrospective multicenter study that included adult patients who received blood transfusions during surgical care in the years 2007 and 2011. The volume of allogeneic red blood cells or autologous blood transfusions (cell salvage and acute normovolemic hemodilution [ANH]) for each case was recorded. The rates of performing appropriate pre-transfusion assessments during and after surgery were calculated and compared between the 2 years. Results We reviewed 270,421 cases from nine hospitals. A total of 15,739 patients received blood transfusions during the perioperative period. The rates of intraoperative allogeneic transfusion (74.8% vs. 49.9%, p  <  0.001) and postoperative transfusion (51.9% vs. 44.2%, p  <  0.001) both decreased from 2007 to 2011; the rates of appropriate assessment increased significantly during (63.0% vs. 78.0%, p  <  0.001) and after surgery (70.6% vs. 78.4%, p  <  0.001). The number of patients who received cell salvage or ANH was higher in 2011 (27.6% cell salvage; 9.3% ANH) than in 2007 (6.3% cell salvage; 0.1% ANH). Conclusion Continuing education and implementation of updated PoBM guidelines resulted in significant improvements in the quality of blood transfusion management in hospitals in Zhejiang, China.

Background Transfusion with red blood cells (RBC) may be needed during hip revision surgery but the appropriate haemoglobin concentration (Hb) threshold for transfusion has not been well established. We hypothesized that a higher transfusion threshold would improve ambulation after hip revision surgery. Methods The trial was registered at Clinicaltrials.gov ( NCT00906295 ). Sixty-six patients aged 18 years or older undergoing hip revision surgery were randomized to receive RBC at a Hb threshold of either 7.3 g/dL (restrictive group) or 8.9 g/dL (liberal group). Postoperative ambulation was assessed using Timed Up and Go-test (TUG) and ability to walk was also assessed daily by a physiotherapist blinded to the allocation. Results Fifty-three patients were able to perform the TUG and included in the analysis. The TUG could be completed in a median of 36 sec vs. 30 sec in the restrictive group and the liberal group, respectively (P = 0.02). The mean difference in TUG was 14.5 sec (95% CI 2.8-26.2 sec). No difference was found in the day patients could perform TUG or walk 10 meters. The Hb at the day of testing was 10.2 g/dL in the restrictive group and 9.9 g/dL in the liberal group. Only 26 patients received RBC. Conclusions A Hb transfusion threshold of 8.9 g/dL was associated with a statistically significantly faster TUG after hip revision surgery compared to a threshold of 7.3 g/dL but the clinical importance is questionable and the groups did not differ in Hb at the time of testing.

Clinical question Does a hemoglobin transfusion threshold of 70 g/L yield better patient outcomes than a threshold of 90 g/L in patients with acute upper gastrointestinal bleeding? Article chosen Villanueva C, Colomo A, Bosch A, et al. Transfusion strategies for acute upper gastrointestinal bleeding. N Engl J Med 2013;368(1):11-21. Study objectives The authors of this study measured mortality, from any cause, within the first 45 days, in patients with acute upper gastrointestinal bleeding, who were managed with a hemoglobin threshold for red cell transfusion of either 70 g/L or 90 g/L. The secondary outcome measures included rate of further bleeding and rate of adverse events.
