Bayesian Health vs VUNO

Last VerifiedAugust 4, 2026
Verdict

Two deterioration models that both run on data the ward already charts, evidenced differently. Bayesian Health holds three large prospective multi site cohort studies with a major academic health system and treated whether clinicians actually respond as part of the system rather than as the hospital's problem, which is the failure this category usually assumes away. VUNO predicts in hospital cardiac arrest within a day from four named vital signs, with independent multicentre validation across several tertiary hospitals and a precisely stated input and output. For a United States hospital Bayesian is the better evidenced and more configurable choice. VUNO's precision about what goes in and what comes out is worth borrowing as a standard, and its Korean validation needs local confirmation before deployment.

Select Bayesian Health if
  • It publishes the first subgroup performance reporting located for any deterioration vendor in this index, and names its architecture plainly.
  • Three large prospective multi site cohort studies with a major academic health system, which is the strongest clinical evidence base here.
  • It engaged with clinician response as part of the system rather than as the hospital's problem.
Select VUNO if
  • It predicts in hospital cardiac arrest within a day from four vital signs the ward already charts, so nothing new has to be collected.
  • Independent multicentre validation across several tertiary hospitals addresses site level generalisability better than most models here.
  • Inputs and outputs are stated precisely, four named vital signs producing a bounded score over a defined horizon.

Disclosure

Both models run on data the ward already collects, which makes local revalidation the practical requirement rather than an optional extra: VUNO's validation is Korean and baseline vital sign distributions, staffing ratios and escalation practices differ enough that performance should be confirmed locally. Bayesian Health publishes no security attestation, business associate posture, hosting terms or pricing. Neither publishes an alert burden per patient day, which determines whether either survives contact with a working ward.
