Stafford Hospital staffing levels 'behind misdiagnosis'
Hospitals will have to publish data on monthly staff levels from next April, in response to a report on the massive failings at Stafford Hospital where hundreds of patients died through neglect.
In 2006, Frank and Janet Robinson's son John died with a ruptured spleen, hours after being sent home from the hospital with painkillers for what his doctor diagnosed as bruised ribs.
Mr Robinson told the BBC he believed staffing levels contributed his son's misdiagnosis.
