A computer disc containing the details of 42,000 ambulance patients has been lost by an East Midlands NHS Trust.
The disc is believed to contain electric copies of scanned handwritten report forms of patients who used East Midlands Ambulance Service from September to November 2012.
The small cartridge has gone missing from the service’s Beechdale headquarters in Nottingham, though there is a possibility that it is still on the premises.
The trust said it ‘had a duty to inform people’ of the incident.
Sue Noyes, EMAS chief executive, said: “We take our responsibility for the security and confidentiality of the information we record and store very seriously, and express sincere apologies for a patient data loss incident, which we have reported to the Information Commissioner.”
Anyone who thinks they might have been affected can contact 0115 884 5055.
