A clinical summary can be grammatically flawless and still omit an allergy, confuse a historical diagnosis with an active condition, or invert a medication change. Verification must be grounded in the original record, not the smoothness of the prose.
Choose a narrowly defined task
Specify whether the system extracts facts, drafts a handoff, or suggests clinical decisions. A summary is not a diagnosis. Require an accountable qualified clinician for any use affecting care, and determine separately whether the software function falls under medical-device oversight. The FDA January 2026 clinical decision-support guidance discusses the characteristics of certain non-device and device software functions; deployment intent matters.
Build a structured source-to-summary check
Extract medications with dose, frequency and stop/start dates; allergies and reaction details; active versus historical conditions; relevant lab dates and units; pending tests; and unresolved ambiguities. Link each statement to an exact source location. A missing source must produce an explicit unknown rather than a plausible completion.
Test the mistakes that are easiest to miss
Create de-identified test cases with contradictory notes, negations, copied-forward history, multiple encounters and changed prescriptions. Measure critical omissions, wrong-person records, wrong dates, unsafe recommendations and unnecessary disclosures separately. A single global similarity score cannot show the frequency of dangerous clinical errors.
Preserve role-based access and accountability
Only retrieve documents authorized for the clinical user. Record which encounter was summarized, the human reviewer and corrections, while avoiding excessive raw health information in logs. Certified health-IT rules about decision-support transparency apply to specific products and modules; they do not guarantee any particular AI summary is clinically reliable.
Example and limits
An emergency handoff identifies a documented severe drug allergy, current treatments and pending investigations. The reviewer checks these against structured medication reconciliation and dated notes before use. The system must abstain on an illegible record. Patient-facing summaries need plain language and clear clinician follow-up, not an implied guarantee of medical accuracy.
