The agency that oversees electronic health records — called eHealth Saskatchewan — did not say how many test results were sent to the wrong doctor offices.
Faxes sent to unintended recipients are potentially considered a privacy breach and the privacy commissioner has been notified.
The agency says affected physicians are being notified that they should check the electronic picture archiving and communications system for their patient exam results, in the event they have not received the written results by fax.
It and the health regions are working to ensure all affected exam results are resent to the ordering physicians and that they have the correct physician fax numbers.
Physicians are being asked to destroy any results they may have received in error and to notify the health region if that occurs.
