So the requirement for this is under the BSQR ; The person responsible for the management of a hospital blood bank shall—
section 9 (1) (e): maintain, for not less than 30 years, the data needed to ensure full traceability of blood and blood components, from the point of receipt of the blood or blood component by the hospital blood bank;

If your colleagues still don't accept this affecting the unambiguous traceability of the units, then they have the responsibility to inform your CEO (as they are the responsible person for the hospital blood bank compliance) with reasons for deviating from the regulations and placing this at risk.

This is really interesting, please keep us updated on how things go as many of us are not getting the IT support we need for improvement projects.
