King's College Hospital NHS Foundation Trust is one of the UK's largest and busiest teaching hospitals, with more than 6,000 staff providing around 700,000 patient appointments per year.
Currently one in seven patients fails to turn up for a scheduled appointment at King's.
About 80 per cent of NHS patients need follow-up consultations and the system will help ensure that emails and letters go to the right place by asking patients to check their details each time they visit, as seen here.
The NCR system can also identify patients who miss appointments allowing staff to reschedule.
