Hundreds of health records for new mums and babies have gone missing.

Health provider Locala has admitted it has suffered a patient data breach after a source contacted the Examiner.

It has confirmed that a file of print-outs for health visitors in the Holme Valley disappeared in November last year and has not been found.

The health organisation, commissioned by the NHS to provide nursing in Kirklees, said the lost lists did not contain personal health details.

But a source said the missing papers included dates of birth and addresses of pregnant women and personal information about when their babies are due to be born and how many times they have been pregnant before.

“This information should only be stored electronically under secure conditions,” the source said.

“This process was ignored by staff and team leaders turned a blind eye,” they claimed.

Locala said it was no longer using print-outs for health visitors and staff were now ordered to immediately shred anything with identifiable information on following a meeting or appointment.

A spokesperson for Locala Community Partnerships, said: “We can confirm that a folder containing printed lists of some – not all – Holme Valley Health Visitor appointments was found to be missing from what was believed to be secure storage at Holme Valley Memorial Hospital.

“The lists were used as a back up to our electronic system and were due for shredding.

“We want to reassure people that, unfortunate as this is, the missing information is not people’s health records.

“The lists contain names, dates of birth and addresses for antenatal and child visits in the Holme Valley. There is no other personal or health history information in the file.

“We do understand that learning about this matter could be distressing for the people involved and we are in the process of writing to them to explain what has happened, what information was on the lists and to apologise for this incident.”

Locala said the missing file had been kept in a locked cupboard in a locked office.

It said the file was never removed from the office and neither this nor any other paperwork had ever gone missing before.

The spokesperson added: “Everyone who has legitimate access to the room was asked if they knew the whereabouts of the folder and asked to check they had not picked it up by mistake.

“The room was thoroughly searched and colleagues also asked to check the folder hadn’t been accidentally collected as an item for posting.

“We want to stress that Health Visitors found the file was missing, rather than this being discovered as part of an audit or some kind of inspection.

“We acted immediately; there was no delay. The discovery was made on November 12, reported the same day and the office search began that day.There's been a patient data breach

“The investigation was completed on November 23 and we have reported the incident as a data loss to the Information Commissioner and informed the service commissioners, Kirklees Public Health.”
