Egton Medical Information Systems (EMIS) began in the 1980s in a rural practice in Egton in North Yorkshire, United Kingdom. The founders, Dr Peter Sowerby and Dr David Stables, wrote the software and adopted the NHS Read Code system during the 1980s. A series of systems have since been deployed in over half of England's primary care practices. The latest product (EMIS Web) moved to a data center based architecture, thin client front end and built in secure web based patient access facilities.
EMIS software looks after the patient records of nearly 40 million people in the UK (30 million using EMIS Web). More than 2 in 3 of those patients can book appointments and order repeat medications online, and more than 1 in 3 can view their own medical record.
EMIS Web features significant advances in terminology use with EMIS adopting a phased approach to SNOMED CT. EMIS Web displays a familiar coding structure based on the construction of a Read Version 2 navigational hierarchy within SNOMED CT. The principle design objective has been to enable SNOMED CT within the clinical system to meet specific requirements, including:
By using coded structured records and providing access to the specialist domain terminology available in SNOMED CT, EMIS has been able to extend the user base of EMIS Web by more than 20,000 new NHS users over the last year. These include practice nurses, community matrons, child health and mental health nurses, palliative care clinicians, diabetes specialists, physiotherapists and psychologists.
