Magpas is an Emergency Medical Charity that provides pre-hospital critical care and retrieval in the East of England with its main area of operations being in Cambridgeshire, Bedfordshire and Peterborough. It trains, equips and deploys a physician-paramedic team known as Helimedix 24/7 to any medical emergency, illness or accident where the NHS Ambulance Service asks for on-scene medical support.
,Magpas was founded as the Mid Anglia General Practitioner Accident Service in 1971 by Dr Neville Silverston OBE. The origins of the name relate to a close historical and geographical association with Cambridgeshire Constabulary which, up until 1974, was known as the Mid Anglia Constabulary. The service was originally provided by General Practitioners from across the Mid Anglia area who were activated by the police and ambulance services to attend serious accidents and provide on-scene care. The charity is now simply known as Magpas:The Emergency Medical Charity.
