Cost Reduction in Blood Transfusions After Implementation of Decision Protocol Based on Hemoglobin and Anemia Symptoms: A Pre-Post Analysis

BACKGROUND Blood products are an expensive resource. The study aimed to assess the cost spent on red blood cell (RBC) transfusions before and after implementing a 2-factorial RBC transfusion decision protocol and the current cost of an RBC transfusion procedure in the local healthcare system. MATERIAL AND METHODS Six-month periods before and after the implementation of the decision protocol were compared. The cost components considered included RBCs, laboratory tests, labor of healthcare workers involved in the procedure, and management of transfusion reactions. RESULTS Following the implementation of the decision protocol, there was a decrease in transfusion costs by €51,411 (56.4%) in our low transfusion rate setting. Inappropriate RBC transfusions amounted to €25,0146 (62.9% of all transfusions costs). The cost of a leucodepleted RBC transfusion increased in the periods being compared, from approximately €109 to €126 in the local healthcare system. CONCLUSIONS Implementing an RBC transfusion decision protocol based on a 2-factorial approach can lead to a more than 2-fold reduction in cost spent on RBC transfusions in a low transfusion rate setting. Even after the implementation of the protocol, further education of clinicians is required, as there may still be potential to reduce costs associated with inappropriate transfusions. The non-RBC acquisition cost of an RBC transfusion procedure approximates the cost of a blood component itself in the local healthcare system.

Acceptability of IV iron treatment for iron deficiency anaemia in pregnancy in Nigeria: a qualitative study with pregnant women, domestic decision-makers, and health care providers

BACKGROUND

Anaemia in pregnancy causes a significant burden of maternal morbidity and mortality in sub-Saharan Africa, with prevalence ranging from 25 to 45% in Nigeria. The main treatment, daily oral iron, is associated with suboptimal adherence and effectiveness. Among pregnant women with iron deficiency, which is a leading cause of anaemia (IDA), intravenous (IV) iron is an alternative treatment in moderate or severe cases. This qualitative study explored the acceptability of IV iron in the states of Kano and Lagos in Nigeria.

METHODS

We purposively sampled various stakeholders, including pregnant women, domestic decision-makers, and healthcare providers (HCPs) during the pre-intervention phase of a hybrid clinical trial (IVON trial) in 10 healthcare facilities across three levels of the health system. Semi-structured topic guides guided 12 focus group discussions (140 participants) and 29 key informant interviews. We used the theoretical framework of acceptability to conduct qualitative content analysis.

RESULTS

We identified three main themes and eight sub-themes that reflected the prospective acceptability of IV iron therapy. Generally, all stakeholders had a positive affective attitude towards IV iron based on its comparative advantages to oral iron. The HCPs noted the effectiveness of IV iron in its ability to evoke an immediate response and capacity to reduce anaemia-related complications. It was perceived as a suitable alternative to blood transfusion for specific individuals based on ethicality. However, to pregnant women and the HCPs, IV iron could present a higher opportunity cost than oral iron for the users and providers as it necessitates additional time to receive and administer it. To all stakeholder groups, leveraging the existing infrastructure to facilitate IV iron treatment will stimulate coherence and self-efficacy while strengthening the existing trust between pregnant women and HCPs can avert misconceptions. Finally, even though high out-of-pocket costs might make IV iron out of reach for poor women, the HCPs felt it can potentially prevent higher treatment fees from complications of IDA.

CONCLUSIONS

IV iron has a potential to become the preferred treatment for iron-deficiency anaemia in pregnancy in Nigeria if proven effective. HCP training, optimisation of information and clinical care delivery during antenatal visits, uninterrupted supply of IV iron, and subsidies to offset higher costs need to be considered to improve its acceptability.

Budget Impact Analysis of Minimally Invasive versus Open Transforaminal Lumbar Interbody Fusion for Lumbar Degenerative Disease: A European Hospital Perspective

Purpose

When traditional therapies fail to provide relief from debilitating lower back pain, surgeries such as transforaminal lumbar interbody fusion (TLIF) may be required. This budget impact analysis (BIA) compared minimally-invasive (MI)-TLIF versus open (O)-TLIF for single-level fusion from an Italian hospital perspective.

Methods

The BIA compared costs of 100 MI-TLIF and 100 O-TLIF procedures from an Italian hospital perspective over a one-year time horizon. The base case included costs for length of hospital stay (LOS), blood loss, and sterilizing surgical trays. The scenario analysis also included operating room (OR) time and complication costs. Base case inputs were from the Miller et al meta-analysis; scenario analysis inputs were from the Hammad et al meta-analysis. The device costs for MI-TLIF and O-TLIF procedures were from Italian tender prices for Viper Prime™ System and Expedium™ Spine System, respectively.

Results

Base case deterministic analysis results showed cost savings of €207,370 for MI-TLIF compared with O-TLIF. MI-TLIF costs were lower for LOS (€215,277), transfusion for blood loss (€16,881), and surgical tray sterilization (€28,232), whereas device costs were lower for O-TLIF (€53,020). The probabilistic result was similar, with MI-TLIF resulting in savings of €211,026 (95% credible interval [CR]: €208,725 - €213,327). All 1000 base case probabilistic sensitivity analysis runs were cost saving. Deterministic scenario analysis results showed cost savings of €166,719 for MI-TLIF. MI-TLIF costs were lower for LOS (€190,813), transfusion for blood loss (€16,881), surgical tray sterilization (€28,232), and complications (€2076), whereas O-TLIF costs were lower for OR time (€18,263) and devices used (€53,020).

Conclusion

Despite the increase incremental cost for medical device innovation and OR time, this study demonstrates the economic savings of MI-TLIF compared to O-TLIF from a European hospital perspective. The findings will be useful to policy and hospital decision makers in assessing purchasing, funding and reimbursement decisions.

[Iron in pre-operative stage and transfusion in patients undergoing hysterectomy]

Background

The correction of preoperative anemia is part of the patient blood management program, in order to improve the patient's clinical results by reducing the number of transfusions in surgery. Uterine fibroids can cause anemia, so the application of iron before hysterectomy could reduce transfusion.

Objective

To evaluate the impact of iron treatment in the preoperative stage on the need for transfusion in patients with anemia secondary to myomatosis in the trans and postoperative stage of hysterectomy.

Material and methods

Patients with uterine myomatosis who presented with microcytic anemia in the preoperative stage were included; clinical records were reviewed, the clinical characteristics of the population were obtained; The patients were distributed into two study groups according to whether or not they had received iron treatment; the outcome variable was the transfusion of packed erythrocytes in the first 7 days after surgery.

Results

134 patients were included, with a median fibroid size of 4 cm. 21 (15.6%) patients used iron. Patients who used iron had a relative risk (RR): 0.36 (95%CI: 0.12-1.07). Delta hemoglobin < 1 g/dL, RR: 1.59 (95%CI: 0.94-2.67). Uterine fibroid size > 5cm had a RR of 1.96 (95%CI: 1.25-3.05).

Conclusion

Treatment with iron in the pre-surgical stage showed a tendency to protect transfusions in the trans and post-surgical stage. The main factor related to transfusion was fibroid size > 5 cm.

Appropriateness of packed red blood cells transfusions in chronic anemic patients in the emergency department: the TRANSFUS-ED retrospective analysis

Patients suffering from chronic anemia can benefit from scheduled transfusions of packed red blood cells (PRBCs), while urgent transfusions have specific indications. These patients frequently seek medical attention in the emergency department (ED), where they can be inappropriately transfused, but research in this field is limited. This study aimed to assess the appropriateness of PRBCs transfusions in chronic anemic patients in the ED. A retrospective analysis was performed on patients who accessed the ED of the Azienda Ospedaliera di Padova (Padova, Italy) between 2016 and 2019 and received PRBCs transfusions. Patients aged ≥ 18 years old and with chronic anemia were included, while those with acute anemia or admitted to the hospital after the transfusion were excluded. Chronic anemia was defined as satisfying one of the following in the past medical history: diagnosis of chronic anemia; two or more previous blood samplings demonstrating anemia; periodic transfusions. As primary outcome, the appropriateness of transfusions was assessed according to the American Association of Blood Banks (AABB) 2016 criteria, using the recommended threshold of 7 g/dL for hemodynamically stable adults and 8 g/dL for patients with pre-existing cardiovascular disease. Out of 1153 transfusions, 344 transfusions were included in the study. According to our criteria, 139 (40.4%) patients were inappropriately transfused, resulting in a total estimated cost of 54,528.71 € in the study period. This study showed that transfusions in chronic anemic patients are recurrent events in the ED and are frequently inappropriate. A possible explanation could be the lack of a well-structured primary care network granting periodic transfusions in ambulatory centers. In the future, implementing and improving chronic anemic patients' access to transfusion services through dedicated pathways could reduce the burden on the ED and also decrease costs.

Severe iron deficiency anemia in the paediatric emergency department: A retrospective study

Background

Transfusion is discouraged in hemodynamically stable children with severe iron deficiency anemia (IDA). Intravenous (IV) iron sucrose (IS) could be an alternative for some patients; however, there is a paucity of data on its use in the paediatric emergency department (ED).

Methods

We analyzed patients presenting with severe IDA at the Children's Hospital of Eastern Ontario (CHEO) ED between September 1, 2017, and June 1, 2021. We defined severe IDA as microcytic anemia <70 g/L and either a ferritin <12 ng/mL or a documented clinical diagnosis.

Results

Of 57 patients, 34 (59%) presented with nutritional IDA and 16 (28%) presented with IDA secondary to menstrual bleeding. Fifty-five (95%) patients received oral iron. Thirteen (23%) patients additionally received IS and after 2 weeks, the average Hgb was similar to transfused patients. The median time for patients receiving IS without PRBC transfusion to increase their Hgb by at least 20 g/L was 7 days (95%CI 0.7 to 10.5 days). Of 16 (28%) children who were transfused with PRBC, there were three mild reactions, and one patient who developed transfusion associated circulatory overload (TACO). There were two mild and no severe reactions to IV iron. There were no return visits to the ED due to anemia in the following 30 days.

Conclusions

Management of severe IDA with IS was associated with a rapid rise in Hgb without severe reactions or returns to ED. This study highlights a strategy for management of severe IDA in hemodynamically stable children that spares them the risks associated with PRBC transfusion. Paediatric specific guidelines and prospective studies are needed to guide the use of IV iron in this population.

Impact of in-hospital intravenous iron supplementation on red blood cell transfusions: experience from an Internal Medicine Unit

BACKGROUND

Pharmacological treatment of iron deficiency anaemia can reduce red blood cell (RBC) transfusions. Intravenous iron provides a more effective and quicker correction of iron deficiency anaemia than oral iron, and third-generation high-dose intravenous iron formulations allow the complete correction of iron deficiency with just one or two drug infusions, thus facilitating iron supplementation therapy and reducing transfusion requirement.

MATERIAL AND METHODS

In an observational, retrospective study we compared RBC transfusion requirement during hospitalisation and within 3 months of hospital discharge in 88 patients with iron deficiency anaemia treated with high-dose ferric carboxymaltose and in 85 patients treated with ferric gluconate while hospitalised in the Internal Medicine unit of our Institution.

RESULTS

Ferric carboxymaltose reduced the number of RBC units given to each transfused patient during hospitalisation (1.81±0.84 vs 2.39±1.49, p=0.011). At hospital discharge, fewer ferric carboxymaltose patients were prescribed home therapy with iron. No differences between treatment groups were observed in the proportion of patients or the number of RBC units transfused within 3 months of discharge. At one month from discharge, however, only 2 ferric carboxymaltose patients had been transfused compared with 7 ferric gluconate patients (p=0.078). Patients transfused post-discharge were more likely to have an underlying malignancy and/or higher serum creatinine concentrations.

DISCUSSION

Treatment with ferric carboxymaltose reduced the number of RBC units per transfused patient. Larger studies are required to define risk factors associated with post-discharge transfusion requirement and to establish if home therapy with iron will reduce subsequent transfusions in patients treated with ferric carboxymaltose.

Organizational Strategies for the Management of Intravenous Iron Therapy in Non-Hospitalized Settings: A Safe Opportunity to Implement Patient Blood Management in Italy

This article analyzes the recommendations issued by the Emilia Romagna region in July 2020 on “Organizational strategies for the safe management of intravenous iron therapy in patients in non-hospitalized settings”. The objective of these recommendations is to set up safe intravenous iron administration sites outside the hospital environment across the national territory. The document facilitates the organization of methods for intravenous iron infusion that are safe for the patient and correct from a medico-legal perspective. In addition, it opens the way for the widespread use of iron infusion in the field, providing benefits to patient quality of life. This program prevents unnecessary transfusions, reduces costs, prevents overcrowding in hospitals in the event of a pandemic, and enables patient treatment in the field, thus, saving on the use of personnel.
