Blood: Donation

Volume 488: debated on Monday 23 February 2009

To ask the Secretary of State for Health what percentage of donated blood was used in each year since 1999. (256709)

The information requested is not available for the entire time period, as data for full 12 month periods have only been submitted and collated since 2005-06.

The Blood Stocks Management Scheme (BSMS) was established by NHS Blood and Transplant (NHSBT) in 2001 with the aim of understanding and improving blood inventory management across the blood supply chain. Hospitals in England, Wales, and Northern Ireland currently submit data on blood usage to the scheme. However, it is important to note that participation is voluntary, and although the majority of hospitals now submit data to the scheme this has gradually increased since its inception.

The following table shows the number of hospitals in England and North Wales providing data to the BSMS; the percentage of units transfused; and the percentage of units not transfused in each year since 2005-06:

1 A validated unit of red cells is one that has been processed, tested, and labelled/validated as fit for issue to hospitals.

2 Participating hospitals have only been submitting data on units transfused for a full 12 months since 2005-06.

3 Figures stated for the percentage of units transfused and not transfused are based on data submitted by hospitals compared against NHSBT figures for number of units issued. There is a small degree of duplication in submitted data due to the transfer of blood between hospitals, meaning some figures exceed 100.
