mobile phone app has speeded up the detection of a potentially fatal kidney condition in hospital patients.
Staff describe the technology as a "potential lifesaver", providing diagnoses in minutes instead of hours.
Data from around 12,000 alerts on acute kidney injury using the new system was evaluated by University College London.
The findings, published in the journal Nature Digital Medicine, found there was "no step change" in patient recovery rates but there had been "significant improvement" in recognising acute kidney injury rapidly.
The report authors have called for further evaluation of the system across a range of hospitals.
