O D negative red cell toolkit
Please note that the current International Society of Blood Transfusion terminology for O negative red cells is O D Negative. This terminology will appear in all resources within the Toolkit that were created after June 2016.
Total red blood cell (RBC) usage is falling due to improved surgical techniques and the implementation of Patient Blood Management (PBM) initiatives including the use of alternatives.
However, O D Negative RBC usage remains constant and in some regions of the country it is actually increasing. Stability of the supply chain for universal components such as O D negative RBC remains a challenge for most blood services around the world and NHSBT is working hard to ensure adequate supplies are available when required.
Efforts are primarily focused on improvement of donor marketing to achieve a blood group mix appropriate to clinical demands. Approximately 7% of the UK population is O D Negative, but current average demand is greater than 12%.
The British Committee for Standards in Haematology (BCSH) guidance on the appropriate use of O D Negative red cells is currently being produced by a writing group led by Dr Megan Rowley. Updates to follow.
As part of their ongoing Action Plan to ensure adequate supplies, the National O D Neg Working Group and NHSBT have launched the following the Save one O D Neg a week campaign. This is designed to encourage Trusts to make a difference and consider a range of initiatives to help conserve this precious resource.
To support this campaign an “O D Neg Toolkit” resource has been produced. It is designed to help clinical and laboratory staff in hospitals to promote the safe and appropriate use of O D negative red cells and reduce wastage of this valuable component. This page will be updated as new resources are produced.
