Current remote patient monitoring reduces readmissions at Dartford and Gravesham NHS Trust


Constrained by workforce shortages during the difficult winter period, Dartford and Gravesham NHS Trust deployed Current, an AI-enabled wearable platform, to remotely monitor patients after being discharged from hospital. The real-time health data provided by Current, enabled Dartford and Gravesham clinicians and staff reprioritise home visits based on criticality, resulting in a 22% reduction in home visits, thereby freeing up skilled nursing time and resources.

Dartford and Gravesham is one of the largest hospital trusts in North Kent, UK, with services at four sites serving a local population of more than 500,000 people. Its overarching clinical strategy is to increase care closer to home to improve patient outcomes. The Hospital at Home team was trained to use Current in less than an hour and began monitoring patients within 24 hours of deployment. Current alerts the Hospitals at Home team when a patient’s health shows signs of deterioration, providing an early warning system that allows for faster intervention.

“The value of Current was demonstrated in our very first patient – a chronically unwell patient who suffered a decline in oxygen saturation, which Current detected sooner than standard care would have caught it, letting us intervene earlier and in the patient’s home,” said Dartford and Gravesham CIO Neil Perry. “With Current, we’ve seen the ability to deliver intervention at a far earlier point and prevent hospital readmission.”

Current is worn on the upper arm where it continually and passively collects vital signs with ICU-level accuracy to provide a complete, automated picture of human health. Its proprietary artificial intelligence (AI) platform analyzes patient data, offering actionable and proactive insights into the wearer’s health.

The Hospital at Home health team identifies which patients can be appropriately managed at home, linking them to Current in just two minutes. Patients are sent home with two Current wearables, a Homehub and a charger. They simply plug in the Homehub to receive reliable in-home WiFi and securely transmit data across the cellular network.

Headquartered in Edinburgh, Scotland, Current (previously snap40) was founded in 2015 by two software engineers, Christopher McCann and Stewart Whiting. With no prior medical experience, their goal is to solve preventable death. The company has raised over $10 million from investors ADV, MMC Ventures and others.
