South Western Ambulance Service NHS Foundation Trust

South Central Ambulance Service, operating under various aliases including SCAS and South Western Ambulance Service, is an NHS foundation trust responsible for delivering emergency and urgent care services. The organisation responds to 999 calls, provides rapid medical assistance at the scene of incidents, and transports patients to appropriate healthcare facilities. In addition to emergency response, it offers non‑emergency patient transport and supports community‑based urgent care initiatives. Its core mission is to deliver timely, clinically effective pre‑hospital care as part of the National Health Service.

The trust’s headquarters is located in the United Kingdom, from where it coordinates operations across its designated service area. As an NHS foundation trust, it is accountable to NHS England and operates under the regulatory framework governing ambulance services in England. It serves communities across its designated service area, working closely with local hospitals, clinical commissioning groups, and other emergency services. Its operational footprint includes a network of ambulance stations, control rooms, and specialist units that enable a rapid response to incidents.

A distinguishing attribute of the trust is its reliance on digital systems for patient information management, exemplified by the use of the MobiMed electronic patient record platform hosted by its IT supplier Ortivus. This system supports clinicians in accessing and updating patient data during emergencies, aiming to improve care coordination and safety. The trust’s involvement in such technology highlights its focus on integrating modern information solutions into pre‑hospital practice. However, this dependence also means that disruptions to supplier systems can directly affect frontline workflows, as demonstrated by a recent cyber incident.

In July 2023, a cyber attack targeted Ortivus, the supplier of the MobiMed system, impacting the South Western Ambulance Service and another trust. The attack disrupted the hosted electronic patient record system, forcing clinicians to revert to manual, paper‑based processes while the supplier worked to restore functionality. Restoration efforts required the supplier to meet NHS security standards before the system could be brought back online, and the trust reported that no patients were directly affected by the incident. This event underscores the importance of cyber resilience within the NHS ambulance sector and the trust’s ongoing efforts to safeguard its digital infrastructure.
