Safer and Smarter Approach to Patient Blood Management

What is Patient Blood Management?

Patient Blood Management (PBM) is a medical approach that focuses on improving patient care by minimizing the need for blood transfusions. It emphasizes preserving a patient’s own blood and carefully considering transfusions only when necessary. PBM aims to optimize the care of patients requiring blood transfusions by improving their overall blood health.

3 Pillars of Patient Blood Management

PBM is built on these three key pillars:

1. Optimizing Erythropoiesis: Erythropoiesis refers to the biological process through which red blood cells are produced in the body. PBM focuses on improving the patient’s ability to make these cells naturally by addressing conditions like anemia, ensuring proper iron levels, and using medications, such as erythropoiesis-stimulating agents, when needed.

2. Minimizing Blood Loss and Bleeding: PBM reduces blood loss during medical procedures and treatment. This because of surgical techniques, blood-conserving technologies like cell salvage systems, and the use of antifibrinolytic medications,

3. Managing Physiological Tolerance to Anemia: PBM emphasizes strategies to help patients tolerate lower levels of hemoglobin. This may include optimizing oxygen delivery, managing fluid, and monitoring to avoid unnecessary blood transfusions.

Benefits

When PBM achieves its goal and gets correctly implemented, it provides multiple benefits, including the following:

• Increased Patient Satisfaction: Patients who undergo PBM experience better outcomes with reduced risk of complications, infections, and recovery times.

• Reduced Dependence on Donor Blood: When PBM is used, patients usually require fewer transfusions, reducing the need for donated blood and alleviating strain on the already limited supply of donor blood.

• Enhanced Recovery and Reduced Hospital Stay: Less blood loss during medical procedures may allow patients to experience faster recovery and a reduced length of hospital stay.

• Healthcare Cost Savings: PBM reduces the need for expensive blood transfusions, lowering healthcare costs.

• Compliance with Regulatory Standards: PBM aligns with regulatory standards and guidelines regarding blood transfusions, such as:

  • World Health Organization (WHO) Recommendations: WHO recognizes PBM as a standard of care and recommends coordinating all blood collection, testing, storage, and distribution at the national level.

  • International Guidelines: Professional societies around the world, such as AABB International Guidelines in the US and the International Society for Blood Transfusion (ISBT), have published guidelines that endorse PBM practices.

  • National and Regional Guidelines: Many countries have integrated PBM practices into healthcare policies, with 128 having national guidelines for proper blood use.

  • Accreditation Standards: Organizations like The Joint Commission and other accrediting bodies emphasize the importance of evidence-based transfusion practices.

Strategies for Implementation

Here are some strategies that make the implementation process of PBM smoother:

• Preoperative Optimization: Assess and treat conditions like anemia or iron deficiency before surgery to improve the patient’s red blood cell mass.

• Intraoperative and Postoperative Blood Conservation: Uses advanced surgical techniques, blood-conserving technologies (e.g., cell salvage systems), and antifibrinolytic medications to minimize blood loss during and after procedures.

• Restrictive Transfusion Thresholds: Focuses on assessing lower hemoglobin levels to decide whether a blood transfusion is necessary for the patients while managing the underlying cause of anemia.

To monitor and improve implementation of the following, it is essential to observe the following:

1. Continuous Monitoring and Management: Implement systems to monitor patient blood levels and manage anemia or blood loss in real time.

2. Compliance Assessment: Evaluate and assess compliance with PBM practices, including preoperative optimization, restrictive transfusion thresholds, and postoperative blood conservation.

3. Use of Advanced Tools and Technologies: Leverage tools like Internet-of-Things (IoT) devices, and air quality and temperature sensors to ensure proper storage and handling of blood products.

Importance of Sensors in Patient Blood Management

As mentioned earlier, proper storage and handling of blood products are crucial for PBM success. Sensors are essential tools for monitoring the temperature, humidity, air quality, and quality control of storage areas. Here’s how they contribute:

1. Contamination Prevention: Sensors monitor air quality in storage areas. It can detect harmful particles or contaminants that could compromise the safety of blood products.

2. Ensuring Proper Storage Conditions: Temperature sensors maintain the precise conditions required for blood storage.

3. Controlling Humidity Levels:Humidity sensors ensure optimal moisture levels to protect blood products and equipment. They prevent damage caused by excessive dryness or dampness.

4. Ensuring Equipment Functionality: Sensors continuously monitor storage equipment performance, such as refrigerators and freezers.

5. Immediate Issue Detection: Advanced sensors deliver real-time alerts for changes in storage conditions. This allows for quick action to prevent losses or risks.
