AI-generated summary — clinician-approved before migration
Chron uses AI to solve the legacy data problem at the heart of every EPR migration.
When a trust migrates from Paris to RiO, from Lorenzo to Nervecentre — the patient data doesn't migrate cleanly. Clinicians inherit thousands of unstructured legacy records. Chron turns them into structured, approved summaries before go-live.
Four steps. No NHS numbers visible after upload.
Upload your EPR export. No NHS numbers visible at any point after upload. Data never leaves Azure UK South.
Chron auto-detects NHS Number, Name, and DOB fields. PII is stripped immediately — CHR tokens assigned before any AI sees the data.
Claude receives only CHR token, age band, and redacted clinical text. Generates structured narrative, diagnoses, and medications — no patient identity involved.
Review queue with bulk approval for high-confidence summaries. Export to PDF, FHIR R4, or direct EPR import. Full audit trail included.
Core Capabilities
Legacy records are messy, duplicated, and unstructured. Chron turns them into clean, clinician-approved summaries — safely.
Claude reads every legacy record and generates a structured clinical narrative — diagnoses, medications, and care history — ready for clinician review in seconds.
Chron's matching engine identifies probable duplicate patient records before migration, flagging them for clinician review. Prevent duplicate histories arriving in your new EPR at go-live.
NHS Number, name, and date of birth are stripped and pseudonymised before any AI processing. Claude sees only a token, an age band, and redacted clinical text.
No summary reaches your new EPR without a clinician approving it. Bulk approval for high-confidence summaries, individual review for flagged or complex records. Full audit trail throughout.
This is the question every NHS IG lead asks first. The answer is built into Chron's architecture — not bolted on as an afterthought.
