In 2011, Oxford University Hospitals (OUH) NHS trust implemented an evidence-based paper "Early Warning" chart, which standardised recognition of deteriorating patients throughout the organisation. Recognising the limitations of a paper-based approach, OUH determined that an electronic solution could further improve patient safety.

Using in-house IT resource alongside human factors and engineering expertise from the University of Oxford, we developed tailored software that allowed compatibility with tablets and bedside devices whilst integrating with the OUH Electronic Patient Record.

The SEND system is currently being used in everyday clinical practice within the whole of the OUH Trust. It has been used to monitor over 100,000 patients to date.
