YAS is one of 10 Ambulance Trusts in England and 13 across the UK. With a fleet of over 600 vehicles, 73 ambulance stations, 3 call centres and over 6,500 staff, the underpinning resilient technology required to provide urgent and emergency care is simple and yet highly complex at the same time. How do we use technology to respond to critical incidents in a target time of 7 minutes and manage the resulting patient data and the transfer to an Acute ED?
