London, May 31 (IANS) Around 750 patients in Britain have won pay-outs worth one million pounds each because of mistakes made by the National Health Service (NHS) over the past 15 years, a media report said.

Such blunders have cost the health service a total of 2.4 billion pounds, the Daily Express reported.

More than half of the mistakes were made during childbirth with 420 cases related to mothers and newborns, it said.

Compensation was paid for 23 leg amputations, and other serious errors that left patients blinded or paralysed.

The biggest payment made was 12.4 million pounds to dancer Kerstin Parkin, 42, who was left brain damaged after having a heart attack while she was in labour at a hospital in Kent in 1996.

A resuscitation team could not get to her quickly because they did not know the security code for her ward.
