What should clinicians look for when buying decision support?
The right tool depends on your workflow, your specialty, your budget, and your scale. Five criteria do most of the work narrowing your shortlist.
Evidence traceability
A CDS answer that can't show its sources is unsafe. UpToDate, OpenEvidence, and Atropos Health all link each statement back to peer-reviewed literature. Generic ChatGPT does not.
Update frequency
Guidelines change. DynaMed updates daily, UpToDate within weeks of major publications, niche tools often lag months. For acute care, this matters.
Specialty depth
VisualDx dominates dermatology, Vera Health emphasizes calculators, Glass Health emphasizes reasoning. No single CDS is best at everything.
Free vs paid
OpenEvidence and DXGPT are free. UpToDate Lexidrug and Micromedex are institutional-only. If you're not in a paying institution, your options are narrower.
EHR embed vs standalone
UpToDate, ClinicalKey, and Doximity GPT embed into Epic/Cerner workflows. Standalone tools require app-switching, which is a workflow tax most clinicians won't pay long-term.
