The chief executive of Whanganui District Health Board has admitted she gave wrong information about a radiologist's workload that sparked concerns about patient safety.
Julie Patterson had told media that Whanganui Hospital's only radiologist was carrying the workload of three-and-a-half full-time doctors.
But Mrs Patterson told a board meeting on Friday she had misinterpreted a briefing from staff, and included work done by a private radiology contractor.
Mrs Patterson says the radiologist is reading scans that would normally be read by just under two fulltime staff in a working week averaging 60 hours.
The increased risk of human error is being managed, she says.
