Errors caused by faulty computer software have led to the wrong organs being removed from 25 organ donors in the UK.
An independent review led by Gordon Duff found the NHS mistakes were caused by faulty software used by UK Transplant to record the wishes of donors, the BBC reported.
It says up to 800,000 people on the donor register may have had their preferences for which organs they wish to donate recorded wrongly.
Duff said NHS Blood and Transplant had already put measures in place to stop errors occurring again.
But he added the database of 17 million people needs better data verification.
The error occurred when data on donation wishes was uploaded using faulty software. The data was taken from the Driver and Vehicle Licensing Agency when it moved to a new computer system.
