The Oxford Acute Referral System (OARS) is a new OCC web app. It supports the complex interactions as teams of doctors, consultants and hospital managers communicate with each other prior to an acute patient referral. This results in a clear and controlled conversation that all stakeholders can see. In future, OARS could even be used to communicate with the patients and their carers as well. The system is compatible with the NHS’s own Electronic Patient Record systems.
