An end-to-end clinical AI solution
AI solutions that work for your hospital.
Every hospital is different. There is no one-size-fits-all AI solution. Signal 1 customizes its models for your patient population and clinical routines. We put our models through rigorous testing and validation before they go live in your hospital. And, with our Signal 1 Monitor, we have eyes on our models so you don't have to. We are your trusted AI partner.
Signal 1 provides an end-to-end AI service:
CHARTWatch: A real-time risk predictor that supports front-line staff while improving flow and quality.
Our first application, CHARTWatch, is a machine-learning based real-time risk predictor that has been in use in St. Michael’s Hospital in Toronto since October 2020. CHARTWatch alerts clinicians when it identifies a patient who is at high-risk for clinical deterioration. Before every shift, CHARTWatch sends patient risk summaries to charge nurses to enable a more appropriate and equitable matching of patients to staff. Read our white paper to learn more about how CHARTWatch improves patient outcomes and enhances hospital efficiency.Read our white paper
When aided by CHARTWatch, clinicians were 15% better at predicting which inpatients would deteriorate.
“CHARTWatch has become a valuable tool for daily patient care, identifying patients at risk of deterioration and enabling clinicians to intervene earlier.”
