Migrate from Openevidence to Epic Ehr.
1 documentation-derived translation pattern — what carries over and what to watch for. Cited to the Feature Parity Map; the audit tells you whether the move is worth it.
OpenEvidence is a standalone clinical search engine: a clinician types a natural-language question and gets a cited, evidence-based answer to act on at the point of care. Epic delivers clinical reference and decision support inside the chart, so a practice already on Epic can stop subscribing to OpenEvidence as a separate reference destination and pull that lookup into Epic itself. Two Epic surfaces cover it: Best Practice Advisories fire in real time on the patient's own data (drug-interaction, allergy, and evidence-based guideline checks), and 'Best Care Choices for My Patient' draws on Cosmos — Epic's de-identified real-world dataset of hundreds of millions of patient records — to show, right in the exam room, how similar patients were treated and what outcomes followed. Because Epic reasons over the live chart and any resulting order is placed on that same record, the clinician gets a patient-grounded answer plus the next action in one place, instead of reading a generic literature answer in OpenEvidence and carrying it back. Keep Epic as the system of record; cut OpenEvidence.
- Warning: Epic's CDS is real-world-evidence and rule-based (Cosmos outcomes + Best Practice Advisories), not a generative literature-synthesis engine — it answers 'how were patients like mine treated' rather than 'summarize the latest published trials with citations'. If clinicians specifically rely on OpenEvidence's narrative, journal-cited literature synthesis (e.g. its DeepConsult agent), confirm Epic's CDS plus your licensed library covers that need before cancelling.
- Warning: Best Care Choices for My Patient and Cosmos require the Cosmos program to be enabled for the org — confirm it is live and configured for the relevant service lines before dropping OpenEvidence.
- Warning: OpenEvidence is free to verified U.S. clinicians, so the 'saving' is removing a parallel workflow/login and the compliance surface of an external tool, not a per-seat license fee — frame the cut as consolidation into the system of record, and re-validate that Epic's in-chart guidance meets clinicians' point-of-care reference habit before retiring the OpenEvidence pathway.
