From the Whistleblower Interview Project:
As a new consultant anesthetist at the Bristol Royal Infirmary, Bolsin identified that too many babies were dying during heart surgery. He spent the next six years exposing the high mortality rates and attempting to improve the service. Bolsin's actions significantly reduced high death rates for children’s heart surgery in The Bristol Royal Infirmary. His whistleblow instigated clinical reform within the NHS and to health care in Australia, New Zealand. Yet he still found himself unemployable in the UK and immigrated to Australia.
