Etiometry Platform vs Isabel Healthcare

Isabel Healthcare sells yearly subscriptions to individual clinicians and residents at public prices. DDx Companion Standard is $149 per year, Premium $199 per year, and the student or resident plan $49 per year, with a 30-day trial of the Companion. Institutions ask for a demo and connect through an API. The vendor says Isabel DDx is in the Cerner App Gallery, that Epic clients get info-button access, and that the correct disease lands in its top ten 96% of the time.

A 2025 Orphanet Journal of Rare Diseases study set it against an interdisciplinary case conference on 100 patients. A summary of the paper reports a top-ten match to at least one conference diagnosis in 28%, and the authors suggest history filtering limited it. An openFDA 510(k) search for "isabel" as applicant or device name returned no record.

The vendor describes Etiometry as a clinical intelligence platform for critical care clinicians, and an individual clinician on a $149 plan is not shopping for an ICU platform. Studies of the platform include a 2025 Critical Care Medicine paper on vasoactive infusion duration after pediatric cardiac surgery and a 2024 JTCVS Open validation of an oxygen-delivery index.
