Perioperative blood transfusion: a plea for guidelines
1Memorial Hospital, Darlington, Durham.
Insights
Many red blood cell transfusions are inappropriate, even in elective surgery. A study found over half of transfusions in this setting did not follow American College of Physicians guidelines, highlighting a need for clearer transfusion protocols.
Area of Science:
- Transfusion Medicine
- Anesthesiology
- Surgical Outcomes
Background:
- Despite awareness of blood product risks, inappropriate red blood cell transfusions persist.
- Elective perioperative settings are a key area for evaluating transfusion practices.
Purpose of the Study:
- To audit avoidable blood transfusion rates in elective surgery.
- To assess adherence to American College of Physicians (ACP) transfusion guidelines.
Main Methods:
- Prospective audit of 82 adult patients undergoing major elective surgery.
- Analysis of 94 homologous SAG-M blood units transfused over 3 months.
- Evaluation against ACP guidelines for red blood cell transfusion indications.
Main Results:
- 53% of transfused units (50 out of 94) were deemed inappropriate per ACP guidelines.
- Common guideline violations included transfusing stable bleeding patients (31%) and asymptomatic patients for hemoglobin >10 g% (22%).
- Significant deviations from recommended transfusion practices were observed.
Conclusions:
- A substantial proportion of perioperative red blood cell transfusions are avoidable.
- There is a critical need for objective, disseminated consensus guidelines for red blood cell transfusion indications.
- Improved adherence to evidence-based transfusion protocols is necessary to optimize patient care and resource utilization.
Abstract:
Red blood cells are still transfused inappropriately in spite of recent media attention and public awareness about the risks of blood products. A prospective audit was conducted to determine the avoidable blood transfusion rates in the elective perioperative setting utilising the guidelines issued by the American College of Physicians (ACP). Of 82 consecutive adult patients who were admitted for major elective surgery over a 3-month period, 28 were transfused a total of 94 units of homologous SAG-M blood, of which 50 (53%) were inappropriate as recommended by the ACP guidelines. Violations of the guidelines were perioperative transfusion in bleeding patients who were haemodynamically stable (31%) and transfusion in asymptomatic, stable patients solely to attain a haemoglobin level above 10 g% (22%). There is a need for objective, easily adaptable and widely disseminated consensus guidelines to the indications for red blood cell transfusion.
