Bayesian Health vs Epic Sepsis Model
The most important comparison in inpatient deterioration, because one of these is already switched on at most American hospitals and the other exists largely because of what independent researchers found when they checked it. The Epic Sepsis Model is proprietary, undescribed, and the most externally validated model in this index, with the best known of those validations reporting performance well below the vendor's own account alongside a heavy alert burden. Bayesian Health is a Johns Hopkins spinout whose evidence is prospective, multi site and peer reviewed, and which treated whether clinicians actually respond to an alert as part of the system rather than as the hospital's problem. If you run Epic you already have one of these and it cost you nothing extra. Ask what it has done at your hospital, measured by someone who does not sell it.
- The evidence is prospective, multi site and peer reviewed rather than retrospective, spanning three large cohort studies conducted with a major academic health system, which is the strongest clinical evidence base of any vendor in this index.
- The model transparency arrives through the published literature rather than a datasheet, which is the stronger form: outside researchers can read how it was built, what it was validated on and how it performed.
- It treated clinician response as part of the system rather than as someone else's problem, which is the difference between a model that fires and a model that changes what happens to a patient.
- It is already there. No new vendor, no new contract, no new data processor, no integration project, and it runs inside the record system the hospital already licenses.
- The deployment footprint is the widest of any product in this index, so a hospital adopting it is not the first to encounter any given failure mode.
- The privacy position is structurally the strongest available, since the model runs inside the existing record system under the existing agreement with no third party receiving patient data.

This pair is the most consequential comparison in the category and the evidence points one way. The Epic Sepsis Model is the most externally validated clinical prediction model in this index, and the most cited of those external validations found substantially worse performance than the vendor's own figures suggested, with a high alert burden and many sepsis cases missed.
Epic publishes no model description, no fairness or subgroup analysis and no performance variation disclosure, at a scale where that absence propagates nationally rather than locally. Bayesian Health publishes no security attestation, no business associate posture, no hosting or residency terms and no pricing, so its own diligence burden is real even though its clinical evidence is not in doubt.
