Patient Blood Management (PBM) Guide
From concept to care centered on Blood Health.
Understand PBM, its Three Pillars, and how Education, Blood Health, prevention of blood loss, and transfusion decision-making come together in a systematic, multidisciplinary, evidence-based model.
Definition
What is Patient Blood Management (PBM)?
Patient Blood Management is a systematic, patient-centered, evidence-based approach designed to improve clinical outcomes through the management and preservation of the patient’s own blood.
The focus shifts from the blood product alone to the patient’s Blood Health: recognizing anemia, preventing blood loss, preserving hemostasis, and individualizing transfusion decision-making.
PBM is neither a single protocol nor a strategy simply to “transfuse less.” It is a care model that organizes decisions throughout the patient journey.
Why change?
Why is PBM needed?
Contemporary care must address anemia, bleeding, variability in transfusion practices, and the limitations of a finite biological resource at the same time. PBM organizes these needs around the patient before transfusion becomes the only response considered.
The goal is to anticipate risk, treat modifiable causes, reduce avoidable blood loss, and make decisions more individualized.
AnemiaRecognize and treat modifiable causes.
Blood lossPrevent and minimize avoidable blood loss.
VariabilityImprove decisions through evidence and protocols.
Blood HealthPreserve an essential component of the patient’s own physiology.
Integrated view
The conceptual structure of PBM
A hierarchical representation of PBM: the overarching concept at the top, Education in a central transformative role, the three clinical pillars, and foundational principles that support care.
Cultural transformation
Education: a key driver of implementation and cultural change
PBM implementation does not depend on protocols alone. It requires continuing education, multidisciplinary alignment, leadership engagement, and sustained attention to patient care.
By strengthening understanding of anemia, blood loss, hemostasis, and transfusion decision-making, Education supports changes that extend beyond individual actions and reach the institution’s culture of care.
Within the PBM framework, Education has a distinct and central role.
The Three Pillars describe the major clinical dimensions of care. Education helps translate these principles into shared knowledge, adherence, consistent practice, and sustainable cultural change.
Clinical structure
The Three Pillars of PBM
The Three Pillars organize the main clinical dimensions of PBM and work in an integrated, individualized way.
Minimize blood loss
Prevent bleeding, preserve hemostasis, and reduce avoidable blood loss throughout care.

PBM does not mean “do not transfuse”
Transfusion can be beneficial and potentially life-saving when appropriately indicated. PBM changes the logic: it addresses modifiable factors, reduces avoidable blood loss, and evaluates the need for transfusion in clinical context.
The goal is not “zero transfusion.” It is to ensure that each patient receives the most appropriate treatment, with transfusion used when its benefits outweigh its risks.
“PBM is not simply about transfusing less. It is about caring for the patient better.”
Educational summary · Blood ManagerBlood Health
Blood Health: Three Ps and Three Es
The Three Ps express the care goals of PBM: Promotion of the best possible hematologic condition, Protection of the patient’s own blood, and Prevention of situations that increase vulnerability, bleeding, or unnecessary transfusion exposure.
This framework is connected to the Three Es: Evidence, Economics, and Ethics, integrating science, sustainability, and patient-centered decision-making.
PromotionPromote the best possible Blood Health for each patient.
ProtectionPreserve the patient’s own blood and reduce avoidable blood loss.
PreventionAnticipate risk and reduce the need for potentially avoidable interventions.

Frequently asked questions
PBM: quick answers
For readers who want a concise answer before exploring the topics in greater depth.
What does PBM mean?
PBM stands for Patient Blood Management, a systematic, patient-centered, evidence-based approach to preserve Blood Health and improve clinical outcomes.
What are the Three Pillars of PBM?
Optimization of red blood cell mass, minimization of blood loss, and increased tolerance of anemia. They are interdependent and should be applied in an integrated manner.
What is the role of Education in PBM?
Education is a central driver for translating PBM principles into practice. It supports multidisciplinary engagement, adherence, implementation, and sustainable change in the culture of care.
Does PBM mean avoiding transfusion?
No. Transfusion remains an important therapy when indicated. PBM seeks to prevent automatic decisions and individualize care based on clinical context and evidence.
Is PBM only for surgical patients?
No. The perioperative setting is important, but PBM principles can also be applied in other clinical settings according to patient needs and the available evidence.
What is the relationship between anemia and PBM?
Anemia is a potentially modifiable risk factor and is part of the first PBM pillar. The approach seeks to identify its cause and optimize red blood cell mass when appropriate. Learn more about anemia →
How does PBM seek to reduce blood loss?
Through prevention, planning, blood-conserving techniques, hemostatic assessment, and strategies adapted to the clinical context. Learn more about hemostasis →
How is transfusion decision-making approached in PBM?
The decision is individualized and should not rely exclusively on an isolated hemoglobin value. Symptoms, physiology, clinical context, and evidence must be considered. Learn more →
Who participates in a PBM program?
PBM is multidisciplinary. Physicians from different specialties, nursing, pharmacy, biomedical and laboratory professionals, transfusion medicine, quality, management, and other areas can contribute according to the institution’s structure.
How can a hospital begin implementing PBM?
Implementation involves leadership, assessment of local needs, education, protocols, indicators, multidisciplinary integration, and continuous improvement. Explore the fundamentals of implementation →
What benefits are associated with PBM?
Structured PBM programs have been associated with more appropriate blood utilization, fewer unnecessary transfusions, and clinical and economic benefits across different settings, with effect sizes varying by population and strategy.
