Tim Bonnici studied medicine at Imperial College and undertook his medical training in London, Poole and Oxford. He is dual-accredited in intensive care and general internal medicine and has a special interest in the management of the acutely deteriorating inpatient on the general hospital ward and the interface between the intensive care unit and the general wards.
His PhD research, undertaken at St Thomas’ Hospital (KCL) and the John Radcliffe Hospital (University of Oxford), examined how wearable monitors and automated algorithms could be used to identify deteriorating ward patients. During this period, working with a multidisciplinary team of biomedical engineers, computer scientists, human factors specialists and clinicians he co-invented SEND, a digital vital signs charting system designed to be intuitive and highly usable. SEND has been cited in numerous NHS and government reports as an example of high quality NHS innovation.
He works as an intensive care consultant at UCLH and maintains an active research interest in digital health applied to patient safety and acute deterioration.
