Signal 1 provides an end-to-end AI service:

Our solution has been in use at a leading academic hospital since 2020.

Our patient deterioration solution is based on algorithms originally developed by researchers at St. Michael’s Hospital in Toronto, Canada where it has been in use since October 2020. Running every hour and automatically updating when new information becomes available, the tool alerts clinicians when it identifies a patient who is at high-risk for clinical deterioration, enabling earlier interventions and better planning.

Improved clinician ability to predict which patients would clinically deteriorate by 15%.

“This solution has become a valuable tool for daily patient care, identifying patients at risk of deterioration and enabling clinicians to intervene earlier.”
