Patient safety has become a growing concern for the NHS. And significant numbers of clinicians are aware of failings in care. Yet when they raise concerns, some find themselves facing allegations themselves and can find themselves suspended from their jobs. They may end up at home on full pay for years at considerable cost to the taxpayer. In some cases clinicians have highlighted serious concerns which, had they been listened to, might have averted subsequent tragedies. In The Report today Simon Cox hears the stories of whistleblowers in the NHS. He asks why their bosses sometimes ignore their concerns and investigates the use of gagging orders and other methods aimed at stopping whistleblowing clinicians from telling their stories.
