Transforming Hospital Care With AI

We are your trusted AI partner.

We work with you through every step of the AI lifecycle. We train and validate our models for your patient population. We collaborate with your clinicians to understand how our model output can best integrate into their workflows. We put our models through rigorous offline validation and silent testing before they go live in your hospital. And, we monitor the performance of our models in your hospital so you don’t have to.

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

We build AI that clinicians want to use.

We work hand-in-hand with doctors and nurses at our partner institutions. Our first application, CHARTWatch, is a machine-learning based early warning system that has been in use in St. Michael’s Hospital in Toronto since October 2020. CHARTWatch alerts care providers when a patient is predicted to clinically deteriorate over the next 48 hours, allowing doctors and nurses to initiate care pathways sooner. Learn more about CHARTWatch and how it is saving lives at St. Michael’s Hospital in our white paper.

33%

CHARTWatch was 33% more effective than clinicians at predicting which inpatients would die over the next 48 hours.

“CHARTWatch has become an indispensable tool, improving patient outcomes and relieving the burden on staff.”

DEEP CLINICAL & TECHNICAL EXPERTISE

We believe AI will transform hospitals.

Years of investments in data and digitization mean hospitals generate more information on patients than ever before. But, information alone will not drive meaningful changes in practice or improvements in outcomes. By translating data into accurate and actionable predictions that are delivered to care providers when and how they want them, Signal 1’s AI platform will help clinical staff provide more timely, more personalized and more consistent care.

Signal 1 was formed out of a partnership between Unity Health, a leader in the application of clinical AI, and Layer 6, a leading applied AI company. With a unique combination of deep clinical expertise and exceptional AI capabilities, we are on a mission to bring clinical AI to hospitals all over the world.

We’ve assembled a team of technologists, clinicians and business leaders who are passionate about transforming patient care.
