Management of perioperative iron deficiency anemia as part of patient blood management in France: A budget impact model-based analysis based on real world data

Outcomes, cost-effectiveness, and ethics in patient blood management

PURPOSE OF THE REVIEW

In this narrative review, we evaluate the recent evidence for benefits, cost-effectiveness, and ethical considerations of patient blood management (PBM) programs.

RECENT FINDINGS

PBM programs are able to reduce the amount of red blood cell transfusion by 20-40% and the risk of reoperation. Lower morbidity and mortality due to PBM implementation were only shown in retrospective studies with a before-and-after design but not in randomized controlled trials. PBM is very likely to be cost-effective when reduced blood transfusion can be accomplished through low-cost interventions, such as administration of oral iron or antifibrinolytics. Further, cost-efficacy can also be achieved by reducing postoperative morbidity and length of hospital stay. Of note, cost-efficacy of PBM interventions might be better in patients at high bleeding risk. Finally, aiming to improve patient's outcome while minimizing transfusion-induced complications, PBM seems highly ethical.

SUMMARY

PBM is an important concept as it promotes the rational use of allogeneic blood products and reduces transfusion and wastage of precious and limited blood products.

Practice Advisory on the Implementation of Preoperative Anemia Management: The Society of Cardiovascular Anesthesiologists and the Society for the Advancement of Patient Blood Management

Preoperative anemia is common and associated with worse outcomes in cardiac surgery including acute kidney injury, red blood cell transfusion, cardiovascular complications, stroke, infection, and death. Patient blood management programs, which include dedicated clinical programs to diagnose and treat anemia in advance of surgery (ie, preoperative anemia programs), have been highlighted as a means to optimize the blood health of each patient, thereby decreasing risk for allogeneic transfusion and improving clinical outcomes. However, there remain implementation challenges for preoperative anemia programs, including difficulties with education of patients and staff, short lead times to address anemia, infrastructure and staffing limitations, lack of clear leadership or ownership of preoperative anemia, the need to develop treatment algorithms and ensure appropriate infusion therapy support, lack of capital support, and insurance/reimbursement concerns, amongst others. The purpose of this advisory from the Society of Cardiovascular Anesthesiologists (SCA) Clinical Practice Improvement Committee and the Subcommittee on Patient Blood Management with endorsement from the Society for the Advancement of Patient Blood Management (SABM) is to provide guidance on the development and implementation of a preoperative anemia clinic or service line, including identification and navigation through potential logistical barriers. A detailed analysis of financial incentives is highlighted in our companion article in this edition focuses on the return on investment of anemia management. Although originating with a focus on anemia before cardiac surgery, this advisory is broadly applicable to all perioperative patients.

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.
