By GlobalDataCHARTWatch is Signal 1’s first application that has been designed to predict patient risk in real-time by using commonly collected data and a machine-learning algorithm.
The application is claimed to accurately predict which hospital patients are likely to deteriorate and which are clinically stable.
The company explained that the predictions made by CHARTWatch could be integrated with a wide range of clinical workflows enabling earlier interventions, reducing excess length-of-stay and improving the allocation of patients to front-line staff. TD Bank Group Transformation, Enablement and Customer Experience senior executive vice-president Christine Morris said: “Signal 1’s focus on better health outcomes will contribute directly to world-leading AI innovation that will benefit all. TD is excited to participate in this ground-breaking work.”
