Development of a Risk Assessment Model for Predicting Red Blood Cell Transfusion in Neonatal Patients.

BACKGROUND: The goal was to develop a risk assessment model for predicting red blood cell (RBC) transfusion in neonatal patients to assist hospital blood supply departments in providing small portions of RBCs to those requiring RBC transfusion on time. METHODS: Clinical information was collected from 1,201 children admitted to the neonatal unit. Clinical factors associated with predicting RBC transfusion were screened, and prediction models were developed using stepwise and multifactorial logistic regression analyses, followed by the evaluation of prediction models using receiver operating characteristic curves, calibration curves, and decision curve analysis (DCA). RESULTS: Overall, 81 neonatal patients were transfused with RBCs, and the variables of gestational age at birth, age < 1 month, receipt of mechanical ventilation, and infant anemia were included in the final prediction model. The area under the curve of the prediction model was 0.936 (0.921 - 0.949), which was significantly higher than that of the individual indicators of gestational age at birth, age at admission < 1 month, receipt of mechanical ventilation, and infant anemia (p < 0.001). DCA showed a standardized net benefit for the possible risk of infant RBC transfusion at 0.1 - 1.0. CONCLUSIONS: We developed a risk assessment model to predict the risk of RBC transfusion in neonatal patients that can effectively assess the risk of RBC transfusion in children.

Cost-Effectiveness and Budget Impact Analyses of Patient Blood Management in a Cardiovascular Surgery Department at Ankara Bilkent City Hospital in Turkey.

INTRODUCTION: Anemia and transfusion of blood products are risk factors associated with poor patient outcomes across all elective surgeries. Patient blood management (PBM) is a patient-centered approach to optimize patient's endogenous red cell mass, to minimize blood loss in patients undergoing surgery, and to harness and optimize patient-specific physiological tolerance to anemia. This study aimed to assess (1) the impact of PBM on blood product usage in cardiovascular surgeries in a state hospital setting, (2) cost-effectiveness of PBM with a model based on transfusion of red blood cells (RBCs) in cardiovascular surgeries, and (3) the budget impact of PBM implementation based on transfusion of RBCs. METHODS: Cost-effectiveness and budget impact models, based on the numbers of avoided transfusions and avoided complications after implementation of the PBM program, were compared between pre- and post-PBM periods at the cardiovascular surgery department of Ankara Bilkent City Hospital between February 11, 2019 and July 24, 2022. The probabilities of transfusions and complications with and without PBM were taken from recent meta-analyses. Data from the Ankara Bilkent City Hospital transfusion center informed the pre- and post-PBM calculations. Costs were calculated from the Social Security Institution's perspective. RESULTS: There was a 21% decrease in the use of RBCs and a 23.7% decrease in use of all blood products after the implementation of PBM. The number of RBC packs per patient reduced by 0.88 packs (21%). The cost saving from reduction of RBC transfusions per patient was 518.68 Turkish lira (TRY) and for the hospital it was 1,635,948 TRY. Fewer complications and lower costs in favor of the post-PBM arm were demonstrated in the cost-effectiveness analysis. On the basis of the budget impact model, in 20 months, the hospital's cardiovascular surgery department saved 6,596,934 TRY (€342,302). CONCLUSION: This hospital-based study demonstrated that PBM is a budget-saving and cost-effective option in Turkey.

When undergoing elective surgery, patients who develop anemia or who need a transfusion of blood products may develop further complications. This study aimed to understand the impact of patient blood management on blood usage in cardiovascular surgeries. Patient blood management is a patient-centered approach that aims to optimize a patient's red cell mass, minimize blood loss in patients undergoing surgery, and maximize a patient's tolerance to anemia. In addition, this study assessed the cost-effectiveness of patient blood management using an economic model based on red blood cells in cardiovascular surgeries and assessed the impact of patient blood management on budget. The patient blood management program resulted in a 21% decrease in use of red blood cells and 23.7% decrease in use of all blood products. The cost savings from reduction of red blood cells transfusions per patient were 518.68 Turkish lira and cost savings for the hospital were 1,635,948 Turkish lira. Fewer complications and lower costs were demonstrated after implementation of patient blood management in the cost-effectiveness analysis. Between December 2020 and July 2022, the hospital's cardiovascular surgery department saved 6,596,934 Turkish lira (€342,302). Overall, this hospital-based study has shown that patient blood management is a budget-saving and cost-effective option in Turkey.

Including the patient in patient blood management: Development and assessment of an educational animation tool.

BACKGROUND: Patient blood management (PBM) programs are effective at reducing transfusion-associated mortality and morbidity; however, patient engagement within the realm of PBM remains relatively unstudied. Our objectives were to develop a novel educational tool utilizing animation to educate preoperative patients about anemia and to evaluate the effectiveness of this intervention. STUDY DESIGN AND METHODS: We created a patient-facing animation for preoperative surgical patients. The animation addressed characters' health journeys from diagnosis to treatment, addressing the role of PBM. We utilized the concept of patient activation as a means to empower patients, and developed the animation to be as accessible as possible. Post-viewing, patients provided feedback utilizing an electronic survey. RESULTS: A final version of the animation can be found here: https://vimeo.com/495857315. A total of 51 participants viewed our animation, the majority of whom were planned to undergo joint replacement or cardiac surgery. Almost all (94%, N = 4) agreed that taking an active role in their health was the most important factor in determining their ability to function. The video was felt to be easy to understand (96%, N = 49), and 92% (N = 47) agreed that they had a better understanding of anemia and its treatment. After watching the animation, patients felt more certain that they could follow through with their PBM plan (98%, N = 50). DISCUSSION: To the best of our knowledge, there are no other PBM-specific patient education animations. Patients enjoyed learning about PBM though animation, and patient education may lead to better uptake of PBM interventions. We hope that other hospitals will be inspired to pursue this approach.

Penny-wise and pound-foolish: the challenges of preoperative anaemia management.

The timely correction of anaemia before major surgery is important for optimising perioperative patient outcomes. However, multiple barriers have precluded the global expansion of preoperative anaemia treatment programmes, including misconceptions about the true cost/benefit ratio for patient care and health system economics. Institutional investment and buy-in from stakeholders could lead to significant cost savings through avoided complications of anaemia and red blood cell transfusions, and through containment of direct and variable costs of blood bank laboratories. In some health systems, billing for iron infusions could generate revenue and promote growth of treatment programmes. The aim of this work is to galvanise integrated health systems worldwide to diagnose and treat anaemia before major surgery.

Is a Patient Blood Management programme economically reasonable?

PURPOSE OF REVIEW: The value of healthcare is defined as the achieved health outcome in relation to the incurred costs. Patient Blood Management (PBM) is a multidisciplinary, evidence-based and patient-centred concept to optimize the patients' red blood cell mass, minimize blood loss and bleeding and to secure the physiological reserve, including the promotion of evidence-based transfusion strategies. This review describes the healthcare value and the cost effectiveness of single PBM measures as well as the implementation of comprehensive PBM programmes. RECENT FINDINGS: Overall, measures improving surgical outcome and reducing hospital length of stay, such as intravenous iron supplementation in iron deficient anaemic patients, the use of antifibrinolytic agents for the treatment of bleeding, the use of cell salvage and adherence to an evidence-based transfusion strategy, are associated with cost savings. SUMMARY: Although several single PBM measures have been shown to be effective and cost-efficient, it remains challenging to compare the results among differing healthcare systems.

Prevalence, Pathogenesis and Management of Anemia in Inflammatory Bowel Disease: An IG-IBD Multicenter, Prospective, and Observational Study.

BACKGROUND: Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD), with a 6% to 74% prevalence and a negative impact on patient survival and quality of life, although the prevalence is apparently declining due to improved disease treatment. We aimed to investigate the prevalence, pathogenesis, and clinical correlates of anemia in Italian patients with IBD. METHODS: A multicenter, prospective, observational study, involving 28 Italian gastroenterology centers, was conducted to investigate the epidemiology and consequences of IBD-associated anemia. Clinical and laboratory data of anemic patients were obtained at study enrolment. RESULTS: Anemia was diagnosed in 737 of 5416 adult IBD outpatients (prevalence 13.6%); females were more commonly affected than males (odds ratio, 1.5; 95% confidence interval [CI], 1.2-1.7) and had more severe anemia. In the majority of cases, anemia was due to iron deficiency (62.5% of cases; 95% CI, 58.3%-66.6%), either isolated or in association with inflammation and/or vitamin deficiencies; anemia of inflammation accounted for only 8.3% of cases. More severe anemia was associated with increasing fatigue and worse quality of life. Only 68.9% of anemic patients with iron deficiency (95% CI, 63.4%-73.8%) and 34.6% of those with vitamin deficiencies (95% CI, 26.2%-44.2%) were properly treated with supplementation therapy. CONCLUSIONS: In Italy, the prevalence of IBD-associated anemia is lower than previously reported. Anemia of IBD is most commonly due to iron deficiency and contributes to fatigue and poor quality of life, but remains untreated in a large proportion of patients with iron and/or vitamin deficiencies. This study is registered at clinicaltrials.gov as NCT02872376.

The prevalence of inflammatory bowel disease­associated anemia is 13.6%. The prevalence is higher among females younger than 50. Anemia is usually due to iron deficiency and adversely affects fatigue and quality of life. Many patients with iron or vitamin deficiency (31% and 65%, respectively) remain untreated.

A Comprehensive Assessment of Blood Transfusions in Elective Thyroidectomy Based on 180,483 Patients.

OBJECTIVES: To assess the incidence, risk factors, and complications of blood transfusions (BTs) in elective thyroidectomy patients. METHODS: A retrospective cohort study was conducted using the American College of Surgeons National Surgical Quality Improvement Program. Adult patients who underwent elective thyroidectomy from 2005 to 2019 were divided into two cohorts based on whether they received BT or not. Multivariable binary logistic regression models were used to identify risk factors of BT and its impact on postoperative complications. RESULTS: Of 180,483 patients, 0.13% received BT. Risk factors for BT included underweight body mass index (BMI) (adjusted odds ratio [OR] 3.179, 95% confidence interval [CI] 1.444-6.996), bleeding disorders (OR 2.121, 95% CI 1.149-3.913), anemia (OR 4.730, 95% CI 3.472-6.445), preoperative transfusion (OR 7.230, 95% CI 1.454-35.946), American Society of Anesthesiology physical statuses 3-5 (OR 3.103, 95% CI 2.143-4.492), operative time >150 min (OR 4.390, 95% CI 1.996-9.654), and inpatient thyroidectomy (OR 5.791, 95% CI 3.816-8.787). In addition, transfusion was independently associated with any postoperative complication, non-infectious, cardiac, pulmonary, renal, vascular, or infectious complications, surgical site infection, sepsis, septic shock, wound disruption, pneumonia, unplanned reoperation, prolonged length of stay, and mortality. CONCLUSION: Recognition of risk factors of BT is imperative to identify at-risk patients and reduce transfusions by controlling modifiable risk factors such as anemia, operative time, and BMI. In cases where transfusions are still indicated, surgeons should optimize care to prevent or adequately manage transfusion-associated complications. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:2078-2084, 2022.

Preoperative anaemia in cardiac surgery: preoperative assessment, treatment and outcome.

Preoperative anaemia is common and associated with increased postoperative morbidity and mortality after cardiac surgery. These findings are supported by a large Dutch cohort study including >35 000 patients published in this issue of the British Journal of Anaesthesia. Timely diagnosis and preoperative anaemia treatment seem to be reasonable targets for perioperative risk stratification and modification. However, implementation of anaemia therapy into clinical routines remains challenging, and evidence for improved outcome is currently limited.

Patient blood management and blood conservation - Complimentary concepts and solutions for blood establishments and clinical services in South Africa and beyond.

Blood transfusions come with risks and high costs, and should be utilized only when clinically indicated. Decisions to transfuse are however not always well informed, and lack of clinician knowledge and education on good clinical transfusion practices contribute to the inappropriate use of blood. Low and middle-income countries in particular take much strain in their efforts to address blood safety challenges, demand-supply imbalances, high blood costs as well as high disease burdens, all of which impact blood usage and blood collections. Patient blood management (PBM), which is a patient-focused approach aimed at improving patient outcomes by preemptively diagnosing and correcting anaemia and limiting blood loss by cell salvage, coagulation optimization and other measures, has become a major approach to addressing many of the challenges mentioned. The associated decrease in the use of blood and blood products may be perceived as being in competition with blood conservation measures, which is the more traditional, but primarily product-focused approach. In this article, we hope to convey the message that PBM and blood conservation should not be seen as competing concepts, but rather complimentary strategies with the common goal of improving patient care. This offers opportunity to improve the culture of transfusion practices with relief to blood establishments and clinical services, not only in South Africa and LMICs, but everywhere. With the COVID-19 pandemic impacting blood supplies worldwide, this is an ideal time to call for educational interventions and awareness as an active strategy to improve transfusion practices, immediately and beyond.

Peri-transfusion quality-of-life assessment for patients with myelodysplastic syndromes.

BACKGROUND: Many patients with myelodysplastic syndromes (MDS) receive red cell transfusions to relieve symptoms associated with anemia, with transfusions triggered by hemoglobin level. It is not known if patients' quality of life (QOL) improves after transfusion, nor if peri-transfusion QOL assessment (PTQA) can guide future transfusion decisions. STUDY DESIGN AND METHODS: We conducted a prospective pilot study of adults with MDS at three centers. Participants, who had to have hemoglobin ≥7.5, completed an MDS-specific measure of QOL (the Quality of Life in Myelodysplasia Scale, [QUALMS]) 1 day before and 7 days after red cell transfusion. A report was sent to each patient and provider before the next transfusion opportunity, indicating whether there were clinically significant changes in QOL. We assessed the proportion of patients experiencing changes in QOL, and with a follow-up questionnaire, whether they perceived their PTQA data were used for future transfusion decisions. RESULTS: From 2018 to 2020, 62 patients enrolled (mean age 73 years) and 37 completed both pre- and post-transfusion QOL assessments. Of these, 35% experienced a clinically significant increase in QUALMS score 7 days after transfusion; 46% no change; and 19% a decrease. Among those completing the follow-up questionnaire, 23% reported that PTQA results were discussed by their provider when considering repeat transfusion. CONCLUSIONS: These data suggest PTQA is feasible for patients with MDS. Moreover, while helpful for some, for many others, red cell transfusion may not achieve its intended goal of improving QOL. PTQA offers a strategy to inform shared decision-making regarding red cell transfusion.

An assessment of the management of anaemia in acute care settings in the United Kingdom: The value of a collaborative approach.

OBJECTIVES: Patients presenting to acute care settings with anaemia are at risk of inadequate investigation and inappropriate blood transfusion. In collaboration with Haematology Specialty Trainee Audit and Research (HaemSTAR), this study set out to assess current red blood cell (RBC) transfusion practice and anaemia management in acute care settings across the United Kingdom. METHODS AND RESULTS: Fifteen different hospitals participated in the study over a period of a month beginning 01 January 2020. Eight-hundred and twenty-eight eligible patients presenting to acute care settings with anaemia received RBC transfusions during this period. Of these, 159 (19.2%) received inappropriate transfusions according to National Institute for Health and Care Excellence guidelines, and 257 (31%) could have been treated with alternatives to transfusion. One-hundred and fifty-four (18.6%) did not have a cause for their anaemia identified by the time they were discharged from hospital, and in over 50% of these cases that was because of inadequate investigation with blood tests, specialist investigation or referral, or both. CONCLUSION: This study found that the appropriateness of transfusion and investigation of anaemia in acute care settings warrant improvement and also demonstrates the value of HaemSTAR in facilitating time-efficient collection of high-quality data.

Associations between preoperative anaemia and hospital costs following major abdominal surgery: cohort study.

BACKGROUND: Determining the cost-effectiveness and sustainability of patient blood management programmes relies on quantifying the economic burden of preoperative anaemia. This retrospective cohort study aimed to evaluate the hospital costs attributable to preoperative anaemia in patients undergoing major abdominal surgery. METHODS: Patients who underwent major abdominal surgery between 2010 and 2018 were included. The association between preoperative patient haemoglobin (Hb) concentration and hospital costs was evaluated by curve estimation based on the least-square method. The in-hospital cost of index admission was calculated using an activity-based costing methodology. Multivariable regression analysis and propensity score matching were used to estimate the effects of Hb concentration on variables related directly to hospital costs. RESULTS: A total of 1286 patients were included. The median overall cost was US $18 476 (i.q.r.13 784-27 880), and 568 patients (44.2 per cent) had a Hb level below 13.0 g/dl. Patients with a preoperative Hb level below 9.0 g/dl had total hospital costs that were 50.6 (95 per cent c.i. 14.1 to 98.9) per cent higher than those for patients with a preoperative Hb level of 9.0-13.0 g/dl (P < 0.001), 72.5 (30.6 to 128.0) per cent higher than costs for patients with a Hb concentration of 13.1-15.0 g/dl (P < 0.001), and 62.4 (21.8 to 116.7) per cent higher than those for patients with a Hb level greater than 15.0 g/dl (P < 0.001). Multivariable general linear modelling showed that packed red blood cell (PRBC) transfusions were a principal cost driver in patients with a Hb concentration below 9.0 g/dl. CONCLUSION: Patients with the lowest Hb concentration incurred the highest hospital costs, which were strongly associated with increased PRBC transfusions. Costs and possible complications may be decreased by treating preoperative anaemia, particularly more severe anaemia.

Hospitalization rates for complications due to systemic therapy in the United States.

The aim of this study was to estimate the trends and burdens associated with systemic therapy-related hospitalizations, using nationally representative data. National Inpatient Sample data from 2005 to 2016 was used to identify systemic therapy-related complications using ICD-9 and ICD-10 external causes-of-injury codes. The primary outcome was hospitalization rates, while secondary outcomes were cost and in-hospital mortality. Overall, there were 443,222,223 hospitalizations during the study period, of which 2,419,722 were due to complications of systemic therapy. The average annual percentage change of these hospitalizations was 8.1%, compared to - 0.5% for general hospitalizations. The three most common causes for hospitalization were anemia (12.8%), neutropenia (10.8%), and sepsis (7.8%). Hospitalization rates had the highest relative increases for sepsis (1.9-fold) and acute kidney injury (1.6-fold), and the highest relative decrease for dehydration (0.21-fold) and fever of unknown origin (0.35-fold). Complications with the highest total charges were anemia ($4.6 billion), neutropenia ($3.0 billion), and sepsis ($2.5 billion). The leading causes of in-hospital mortality associated with systemic therapy were sepsis (15.8%), pneumonia (7.6%), and acute kidney injury (7.0%). Promoting initiatives such as rule OP-35, improving access to and providing coordinated care, developing systems leading to early identification and management of symptoms, and expanding urgent care access, can decrease these hospitalizations and the burden they carry on the healthcare system.

Screening and treating pre-operative anaemia and suboptimal iron stores in elective colorectal surgery: a cost effectiveness analysis.

Our study investigated whether pre-operative screening and treatment for anaemia and suboptimal iron stores in a patient blood management clinic is cost effective. We used outcome data from a retrospective cohort study comparing colorectal surgery patients admitted pre- and post-implementation of a pre-operative screening programme. We applied propensity score weighting techniques with multivariable regression models to adjust for differences in baseline characteristics between groups. Episode-level hospitalisation costs were sourced from the health service clinical costing data system; the economic evaluation was conducted from a Western Australia Health System perspective. The primary outcome measure was the incremental cost per unit of red cell transfusion avoided. We compared 441 patients screened in the pre-operative anaemia programme with 239 patients not screened; of the patients screened, 180 (40.8%) received intravenous iron for anaemia and suboptimal iron stores. The estimated mean cost of screening and treating pre-operative anaemia was AU$332 (£183; US$231; €204) per screened patient. In the propensity score weighted analysis, screened patients were transfused 52% less red cell units when compared with those not screened (rate ratio = 0.48, 95%CI 0.36-0.63, p < 0.001). The mean difference in total screening, treatment and hospitalisation cost between groups was AU$3776 lower in the group screened (£2080; US$2629; €2325) (95%CI AU$1604-5947, p < 0.001). Screening elective patients pre-operatively for anaemia and suboptimal iron stores reduced the number of red cell units transfused. It also resulted in lower total costs than not screening patients, thus demonstrating cost effectiveness.

Impact of gender parity on preoperative anaemia prevalence and Patient Blood Management practice.

BACKGROUND: Anaemia is a common finding in the preoperative setting, affecting around one-third of patients for whom major surgery is programmed. Moreover, preoperative anaemia has been shown to worsen patient outcome and increase length of hospital stay and costs. In the field of preoperative anaemia correction, a recent Consensus statement suggested reviewing the classic World Health Organization (WHO) criteria in adults by aligning the haemoglobin cut-off to 13 g/dL for both genders. The aim of our study was to assess the differences in terms of prevalence, transfusion rate, transfusion trigger, and blood losses according to gender in a mixed population of surgical patients. MATERIAL AND METHODS: We reviewed data of 610 consecutive patients undergoing elective major surgery at a tertiary care hospital during a 9-month period. Transfusion rate and transfusion triggers were recorded, analysed and stratified by haemoglobin class, with a particular focus on the 12.0-12.9 g/dL range. RESULTS: Since the anaemia threshold was redefined at 13 g/dL for both genders, its prevalence rose from 26.4 to 39.5% (161/610 vs 241/610; p<0.001) in the overall population and from 22.7 to 49.3% (68/300 vs 148/300; p<0.001) in women. Eighty women (26.7%) fell in the haemoglobin 12.0-12.9 g/dL range, and this category was the most represented among transfused women (34.0%). There was no statistical difference in transfusion triggers or overall transfusion rate between genders. Subjects of both genders were transfused at the same haemoglobin level (8.1 g/dL), but women reached the transfusion trigger after less red cell mass loss than men, i.e. 377 mL (249-472 mL) vs 528 mL (356-717 mL), respectively (p<0.001). DISCUSSION: Treatment of pre-surgical anaemia is one of the core principles of Patient Blood Management. Aligning the haemoglobin threshold between genders in the management of pre-surgical anaemia may result in a lower transfusion rate, but in an increased workload for medical staff in the preoperative phase.
