A single unit transfusion policy reduces red cell transfusions in general medical in-patients.

BACKGROUND

The NICE guidelines for blood transfusion and the patient blood management recommendations state that a single unit of red cells should be the standard dose for patients with stable anaemia who are not bleeding. Studies have shown that changing clinical transfusion practice can be difficult and that many clinicians' order two units of blood as standard for patients needing a transfusion.

AIM

A collaborative project between NHS Blood and Transplant and Kings College Hospital started in September 2014 to evaluate the impact of a single unit policy on blood usage.

DESIGN METHODS

Training and education was undertaken for clinical staff on eight general medical wards and all staff working in the blood transfusion laboratory. We collected transfusion data for 12 months, (6 months before and after implementation).

RESULTS

There was a decrease of 50% red cell unit usage between the two periods, equating to a unit cost saving of £28 670. The number of single unit transfusions, increased from 30 to 53% whilst the number of two units decreased from 65 to 43% (P < 0.001).

DISCUSSION/CONCLUSION: This project has shown that transfusion practice can be changed and savings in blood usage can be achieved through the successful implementation of the single unit transfusions policy. Key to the implementation was engagement from key medical staff within the medical department in which the policy was implemented and support from the hospital transfusion team. Continued attention and training shall be needed to support these, and implement other, patient blood management recommendations.
