'Clinically significant' mistakes: 700 patients' X-rays and scans misread at Terrace hospital

Northern Health has notified 700 patients and their doctors of "clinically significant" errors in the interpretation of their X-rays, ultrasoundsand CT scans at the hospital in Terrace.

But Northern Health has no plans to monitor or track whether those errors end up harming patients.

'We cannot speculate ... as to ... adverse impact'

"We cannot speculate or provide any information as to whether there has been any specific adverse impact,"said Northern Health communications officerErynCollins in a written statement.

Any follow up is now the responsibility of family physicians, said Collins.

Collins saidthe corrected radiological resultshave now been shared with the affectedpatients' doctors "so that they can determine if a discrepancy resulted in any change in diagnosis or treatment and follow up accordingly."

"We are not privy to those doctor-patient diagnosis and treatment discussions," Collins told CBC News in an email.

700 patients told of 'clinically significant" errors'

The errors came to lightafter Northern Health asked a team of radiologists from Vancouver General Hospital to takea second look at more than 8,400 images taken by one radiologist over a five month period at Terrace's Mills Memorial Hospital.

Collins saysthe expertreview "resulted in a different interpretation that is considered clinically significant" for10.3 per cent of the images.

"The radiologist who reread an image came to a different conclusion about what it showed," said Collins.

Northern Health doesn't plan to monitor outcomes

Collins says the results have the potential to alter patient follow up or treatment.

But since imaging tests are just one factor in diagnosis andtreatment,"it doesn't necessarily mean there are clinical concerns or adverse health impacts to the individuals affected,"said Collins.

The radiologist who misread the images has been on voluntary leave.

A medical advisory committee will now advise Northern Health's board about the individual's future professional practice.
