Records of patients from the Audiology Department were lost
A computer failure at NHS Forth Valley led to the loss of records for all patients being treated at its audiology department, the BBC has learned.
The health authority said the majority of the information had been recovered, although a "small number" of records were still missing.
It is understood that the records were lost last week resulting in a number of appointments being cancelled.
The authority has issued an apology to those affected.
In a statement they said: "We can confirm that there has been a problem with the audiology computer system.
"As a result staff were unable to access patients records for a number of days and regrettably patients who were due to be seen were told that their appointments would have to be re-arranged.
"The system is now up and running again and work is under way to identify what went wrong and to put in place steps to ensure that this does not happen again.
"We are obviously very sorry for the inconvenience to our patients and are doing everything to make sure they are seen as soon as possible."
The authority has not revealed how many patients were affected by the data loss.
