A wastewater trend brief for the public health desk
The U.S. CDC National Wastewater Surveillance System publishes pathogen trends from sewage, which health departments read next to emergency and lab data. Some jurisdictions add a statistical nowcast on top of that feed. This card is about the desk workflow, not a claim that a named model forecasts incidence with a stated error. Wastewater is a population signal. It does not diagnose a person.
Clinical setting
A city or state public health epidemiology desk during respiratory-virus season, briefing hospitals on whether trends are rising.
Tools and vendors
CDC NWSS
Local epidemiology desk
What was reported
No model error rate is quoted. Use the CDC program pages and the local health department method note for what a given jurisdiction actually publishes.

This is an illustrative composite, not a trial report. A registry ranks patients who are overdue for a fit test, mammogram, or other screening the health system already recommends. Navigators call down the list. Before anyone trusts the rank order, the team checks whether the score under-calls a language group, a neighborhood, or a payer. No detection-rate improvement is claimed. A biased rank can widen a gap the program meant to close.
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.
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.
