A patient received confidential details of several other people in the post after an error by a Northamptonshire NHS trust.
The diabetes patient received the names and addresses of 12 patients in a letter sent to their home address.
It is understood the letter, from the Diabetic Retinal Screening Service, was an appointment and the patient complained to Northamptonshire Healthcare NHS, which runs the service. The error was included in the trust’s most recent serious incident report, which covered incidents since April.
A spokesman for Northamptonshire Healthcare NHS Foundation Trust (NHFT) said: “Ensuring patient confidentiality is one of our top priorities and any breaches of this principle are a cause of great concern for us.
“In this instance, human error meant that a piece of paper with some patient names on was inadvertently included in the envelope with a letter to a patient using the Diabetic Retinal Screening Service.
“This has been recorded as a serious incident. Since this incident we have reviewed our procedures to ensure there is greater quality control and checking before any patient letters are sent out.”
The report said it was noted as part of the investigation into the error that management roles within the team were not clearly identified. This has now been reviewed.
