Summary
Digital methods significantly increased transfusion reaction detection by 524%, enabling real-time intervention. This hemovigilance approach enhances patient safety and could be applied to other critical care events.
Area of Science:
- Transfusion Medicine
- Patient Safety
- Health Informatics
Background:
- Transfusion reactions are often underdiagnosed due to passive reporting systems.
- There is a need for improved methods to detect transfusion reactions in real-time.
Purpose of the Study:
- To investigate the utility of digital methods for identifying potential transfusion reactions.
- To enable real-time intervention for patients experiencing transfusion reactions.
Main Methods:
- A hemovigilance unit monitored patients and transfusions, comparing retrospective data.
- Algorithms were developed in the electronic health record to analyze vital signs and assign risk scores.
- Hemovigilance nurses remotely monitored patients, prioritizing real-time chart reviews by risk score.
Main Results:
- A 524% increase in diagnosed transfusion reactions was observed compared to passive reporting (1.3% of transfusions).
- Rapid response providers reached patients within an average of 12.4 minutes, demonstrating feasibility.
- Recognition of transfusion-associated circulatory overload significantly increased.
Conclusions:
- A digitally-enabled, real-time expert review model improved transfusion reaction recognition.
- This approach holds potential for early identification of other patient deterioration events, such as sepsis.

1.0K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
