The service developed mobile technology for its entire emergency fleet of over 600 vehicles using GPRS connectivity. Cab-based technology involves each vehicle having two units: a front unit with sat nav and incident management and a rear unit with a purpose-designed electronic health record. This links to the clinical database, auto-updates as required, and transmits the record electronically to receiving clinicians. Clinical reporting is now paper-free, and the unit is a hub for connection to other clinical devices.
