A simple program to improve the appropriateness of red blood cell transfusions in non-bleeding hospital patients: a before-and-after study.

Introduction: Transfusion of red blood cells (RBCs) is not devoid of risks; nor is anemia. The aim of the study was to assess the usefulness of a program designed to improve the appropriateness of RBC transfusions in hospital patients.Methods: We retrospectively analyzed time periods before and after program implementation. Results: Before program implementation 415 out of 23492 (1.8%) patients received at least 1 RBC, whereas after implementation 162 out of 25062 (0.6%) did so. The percentage of appropriate RBC transfusions increased from 23.6 to 37.1%. Conclusions: A simple program may lead to a 3-fold decrease in transfusion rate and a significant increase in the percentage of appropriate RBC transfusions.

Does training make a difference? Proficiency training in transfusion guidelines and its effect on red blood cell administration.

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.

Transfusion Complications in Thalassemia: Patient Knowledge and Perspectives.

Chronic transfusion, used to manage clinically significant forms of thalassemia, carries complication risks including iron overload, alloimmunization, and allergic or hemolytic reactions. Dissemination and implementation of evidence-based guidelines for minimizing these risks are complicated by the small numbers and increasing dispersion of the thalassemia population. This elevates patients' role in understanding and communicating with providers about treatment. The present study sought to assess thalassemia patients' knowledge of transfusion, complications, and guidelines; their experience of clinicians' following guidelines; and their perspectives on ways to store and share personal transfusion data. A convenience sample of 32 patients participated in structured interviews. Most, if not all, understood iron overload, chelation therapy, blood typing, and cross-matching. Awareness of each of five of evidence-based transfusion guidelines that were discussed ranged from 72 to 88%. Patients expressed privacy concerns about each of three data storage options, slightly less for a registry than for a wallet card or smartphone app. The registry also avoided concerns that the other options placed extra burden on patients. Recommendations include increased education on the meaning and significance of packed, washed red blood cells, leuko-reduction, and detailed cross-matching, and implementation of a nationwide registry to make transfusion data available to providers anywhere at the point of care. Registry implementation should be sensitive to patients' privacy and security concerns, but also help them appropriately weigh those against safety benefits. These actions could help reduce transfusion complications in thalassemia by improving patient efficacy and increasing adherence to evidence-based guidelines.

Efficacy of packed red blood cell transfusions based on weight versus formula in thalassemic children: An open-label randomized control trial.

BACKGROUND: Protocols for transfusion therapy in transfusion-dependent thalassemia (TDT) children differ among various medical centers. In India, most centers consider only the patient's weight while calculating the volume of packed red blood cells (PRBCs) to be transfused. This study aimed to compare the efficacy of PRBC transfusions of different volumes calculated either by weight or by a formula using weight and pretransfusion hemoglobin of patient and hematocrit of PRBC. STUDY DESIGN AND METHODS: Sixty TDT patients in the age group of 3-9 years were enrolled and randomly allocated to two groups. Group A received PRBC transfusion volume based on the patient's weight, and Group B received PRBC volume calculated using a formula for 6 months. RESULTS: Average pretransfusion hemoglobin in Group A and Group B (9 ± 0.4 vs. 8.9 ± 0.4 g/dl) was not significantly different (p = .353). Although the average number of visits in 6 months was less for Group A compared to Group B (7 ± 1 vs. 8 ± 1; p = .001); the average volume transfused per visit was more (351 ± 78 vs. 287 ± 68 ml; p = .003). The calculated average annual pure red cell requirement of the patients was 178 ml/kg/year for Group A and 154 ml/kg/year for Group B (p = .000). Total donor exposures were significantly lower in Group B than Group A (11 ± 3 vs. 14 ± 3; p = .006). CONCLUSION: The number of donor exposures and annual pure red cell requirement was significantly lower in the formula-based group. Transfusions based on formula are recommended in TDT patients.

Platelet Transfusion-Insights from Current Practice to Future Development.

Since the late sixties, therapeutic or prophylactic platelet transfusion has been used to relieve hemorrhagic complications of patients with, e.g., thrombocytopenia, platelet dysfunction, and injuries, and is an essential part of the supportive care in high dose chemotherapy. Current and upcoming advances will significantly affect present standards. We focus on specific issues, including the comparison of buffy-coat (BPC) and apheresis platelet concentrates (APC); plasma additive solutions (PAS); further measures for improvement of platelet storage quality; pathogen inactivation; and cold storage of platelets. The objective of this article is to give insights from current practice to future development on platelet transfusion, focusing on these selected issues, which have a potentially major impact on forthcoming guidelines.

Perioperative anemia: clinical practice update.

Perioperative medicine is an evolving area of medicine in which collaboration between internists, hospitalists, surgeons and anesthesiologists is the key to delivering high-quality care. Research in all areas of perioperative medicine, including perioperative anemia, is constantly evolving. Perioperative anemia is a major contributor to mortality and morbidity in the perioperative period. It is associated with an increased likelihood of postoperative wound complications, infections, delirium, increased length of stay and increased risk of readmissions. However, there is a lack of comprehensive guidelines for management of perioperative anemia. We performed an exhaustive review of contemporary literature on perioperative anemia and present evaluation and management recommendations that have the potential to impact clinical practice in the perioperative period.

Evaluation of a novel Cardiac Peri-Operative Transfusion Trigger Scoring system in patients with coronary artery disease.

BACKGROUND: A simple and accurate scoring system to guide perioperative blood transfusion in patients with coronary artery disease (CAD) undergoing cardiac surgery is lacking. The trigger point for blood transfusions for these patients may be different from existing transfusion guidelines. This study aimed to evaluate the safety and efficacy of a new scoring strategy for use in guiding transfusion decisions in patients with CAD. METHODS: A multicenter randomized controlled trial was conducted at three third-level grade-A hospitals from January 2015 to May 2018. Data of 254 patients in a Cardiac Peri-Operative Transfusion Trigger Score (cPOTTS) group and 246 patients in a group receiving conventional evaluation of the need for transfusion (conventional group) were analysed. The requirements for transfusion and the per capita consumption of red blood cells (RBCs) were compared between groups. RESULTS: Baseline characteristics of the two groups were comparable. Logistic regression analyses revealed no significant differences between the two groups in primary outcomes (1-year mortality and perioperative ischemic cardiac events), secondary outcomes (shock, infections, and renal impairment), ICU admission, and ICU stay duration. However, patients in the cPOTTS group had significantly shorter hospital stays, lower hospital costs, lower utilization rate and lower per capita consumption of transfused RBCs than controls. Stratified analyses revealed no significant differences between groups in associations between baseline characteristics and perioperative ischemic cardiac events, except for hemofiltration or dialysis and NYHA class in I. CONCLUSIONS: This novel scoring system offered a practical and straightforward guideline of perioperative blood transfusion in patients with CAD. Trial registration chiCTR1800016561(2017/7/19).

Laboratory Monitoring and Transfusion Guidelines to Influence Care in Patients Undergoing Multilevel Spinal Fusion Surgery.

PURPOSE: The purpose of this project was to determine whether the use of the modified Northwestern high risk spine protocol in patients undergoing multilevel spinal fusion surgery would result in improved transfusion practices. DESIGN: Preimplementation and postimplementation design. METHODS: A laboratory monitoring and transfusion guideline protocol was implemented in patients undergoing multilevel spinal fusions. Data were collected via a manual retrospective chart review of the electronic medical record before and after implementation of the protocol. FINDINGS: Laboratory values were monitored at guided intervals. There was a statistically significant (P = .004) decrease in the mean hemoglobin value at which a packed red blood cell transfusion was initiated. CONCLUSIONS: Through the use of the protocol, laboratory value monitoring provided quantitative data to aid and improve clinical decision making for practitioners in the perioperative period.

Implementing a patient blood management program in Norway: Where to start?

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

Reduction of the Platelet Transfusion Dose and Its Effects / 대한진단검사의학회지

BACKGROUND: In Korea, a platelet transfusion dose (TD) of 8 units of platelet concentrates (PC) is usually used. To minimize the shortage of blood products and transfusion-related adverse reactions, the TD has been changed from 8 to 6 units in 2006 in our hospital. Here, we analyzed the dose reduction effect on patients' platelet counts and transfusion frequency. METHODS: We compared the amount of issued PC, platelet counts before and after transfusion, post-transfusion platelet increments, and transfusion frequencies in patients who were transfused with 8 PC in 2006 and 6 PC in 2008. RESULTS: Despite an increase in the number of admitted patients by 20% in 2008 with a disease distribution similar to that in 2006, the number of issued PC in 2008 was decreased by 26.6% compared to that in 2006. In 2008, post-transfusion platelet counts, pre-transfusion platelet counts in patients transfused with 320 mL whole blood-derived PC, and platelet increments in patients transfused with 400 mL whole blood-derived PC were significantly decreased. However, the mean transfusion frequency per one month was not significantly different, 4.3 times in 2006 and 4.7 in 2008. CONCLUSIONS: By implementing a policy of platelet TD restriction, the amount of total issued PC was markedly decreased. Although post-transfusion platelet counts were decreased, the transfusion frequency in a month was not significantly increased. The restriction of platelet TD was helpful for increasing physicians' recognition of blood shortage while achieving similar transfusion effects. We conclude that 6 units of PC would be a better guideline for the platelet TD.
