AION Fidelity Audit — Prove what actually arrives.
At every system boundary, clinical data loses meaning: HIS migration, record digitisation, lab integration, EHR export. Your vendor reports “transferred successfully” — we measure what of the meaning has arrived. The Fidelity Audit measures meaning fidelity: the share of losslessly transferred messages in the total set |E| — as a headline figure that holds, verifiable down to the input hashes.
Why the Fidelity Audit is different.
No sampling by gut feel, no “looks fine.” A measurement method with a published mathematical foundation — and without your patient data ever leaving your house.
Mathematically complete, published.
Four loss patterns, formally proven complete and minimal (FM-4, Zenodo DOI 10.5281/zenodo.20391260). We don’t look for just any errors — we cover the entire loss space.
Your data never leaves your house.
The audit runs on-premise; only the report reaches us — without any patient content.
26 years as an engineering firm.
ISCaD GmbH, founded in 2000 — references including Deutsche Telekom, Region Hannover, EXPO 2000. And: the same measurement chain runs in production on our own systems.
The Quick Check.
Up to 100 messages, a short report with headline figure and top findings — €990 fixed price, results within 3 working days. Credited when you commission the full audit: your entry effectively costs nothing if you continue.
From scoping to a verifiable report.
Scoping (0.5–1 day)
We clarify system boundaries, formats and the relevant export pairs for the measurement run.
Adapter fit
HL7 v2, FHIR and CSV immediately; proprietary formats via adapter.
Measurement run
We measure with your real export pairs — on-premise, without any patient content leaving your house.

The Fidelity Audit is a quality-assurance and interoperability tool. It is not a medical device and makes no clinical assessment — it measures the completeness of meaning transfer between systems.
