The Targeted Real-time Early Warning System (TREWS) watches the electronic record and asks a clinician to confirm or dismiss a possible sepsis alert. It was studied prospectively across five hospitals, not as a silent background score. The published association depends on a person acting on the alert within a few hours. It does not diagnose sepsis by itself.

Among patients with sepsis identified before antibiotics, confirmation of the alert within 3 hours was associated with an adjusted absolute mortality difference of 3.3 percentage points (relative 18.7%) versus alerts not confirmed in that window (Nature Medicine, 2022). A companion paper reported a 1.85-hour shorter median time to the first antibiotic order for the same comparison. These are associations with how the alert was used, not a randomized trial of the model.

The Epic Sepsis Model is a proprietary score switched on in a large number of U.S. hospitals. Researchers at Michigan Medicine compared it with sepsis in their own hospitalizations, instead of relying on the vendor performance sheet. The paper is included here because a familiar model can still fail local validation. Widespread deployment is not the same thing as demonstrated usefulness.
This is an illustrative composite, not a trial report. A unit feeds monitor alarms through a second layer that withholds repeats already explained by motion, a loose lead, or a value the nurse just acknowledged. The bedside alarm for a new life-threatening rhythm still sounds. The point of the scenario is the governance question: who is allowed to silence what, and how a missed true alarm would be reviewed.
This is an illustrative composite, not a trial report. Each morning the rapid-response nurse opens a list that combines a NEWS2-style vital-sign score with a model score from the record. The huddle decides who needs a bedside review. The score does not page a code team, order labs, or write a note. Hospitals using a vendor deterioration index should repeat a local check before trusting the threshold, as the sepsis literature already shows.
