Bayesian Health vs Etiometry Platform

PubMed papers on the Etiometry platform include a 2025 Critical Care Medicine paper on vasoactive infusion duration after pediatric cardiac surgery and a 2024 JTCVS Open validation of the oxygen-delivery index in an adult cardiovascular ICU. The vendor lists four FDA-cleared risk indices for oxygen delivery, ventilation, lactate and acidosis, with 11 clearances on record since 2015. IDO2 covers post-surgical children and adults 18 and over, while the other three are indicated for children up to 12. In observational data the vendor claims up to 36% shorter stays and up to 41% fewer ICU readmissions. Its buyers are pediatric and adult cardiac surgery ICU directors.

Bayesian Health serves a hospital medicine chief watching ward patients for sepsis. These are separate purchases, because Etiometry reads bedside monitor data in post-surgical and ventilated ICU patients and Bayesian reads EHR data for sepsis risk. Bayesian's evidence is a 2022 Nature Medicine study of the TREWS system across five hospitals and 764,707 encounters, with 82% sensitivity and alerts 5.7 hours earlier according to the company's release.
