Zaznavanje MRN po meri za HIPAA brez kode

Stevilke medicinskih kartotek so specificne za bolnisnico - vsak zdravstveni sistem uporablja drugacen format. HIPAA Safe Harbor zahteva odstranitev MRN.

Tezava formatov MRN

ZDA ima priblizno 6.100 bolnisnic. Vsaka ima svoj sistem EHR. Vsaka uporablja lasten format stevilke medicinske kartoteke (MRN). Ne obstaja nacionalni standard. Skupna komisija zahteva, da bolnisnice prepoznajo paciente - vendar ne doloca pravil za formate.

Formati so zelo razlicni. Nekateri so 7-mestna cela stevila. Drugi so 8-mestna cela stevila. Nekateri uporabljajo predponske kode, kot so HOSP-, MRN- ali PT-. Drugi dodajajo institucionalne kode, kot so SVHS- ali CHOP-. Nekateri v stevilko vkljucijo leto vpisa.

HIPAA Safe Harbor navaja stevilke pacientnih kartotek kot identifikator vrste 8 od 18. (45 CFR §164.514(b)(2)) Vseh 18 mora biti odstranjenih. Pravilo tega ne omejuje na en sam format. Ce vasa bolnisnica uporablja format po meri, ga morate zaznati. Orodje, ki ga zamudi, ne izpolni Safe Harbor - tudi ce odstrani vseh ostalih 17 vrst.

Zakaj pristop s kodo ne deluje

Standardni nacin dodajanja formata kartoteke po meri v postopek de-identifikacije je razsiritev Microsoft Presidio. To pomeni pisanje Pythona.

Razvijalec ustvari razred, ki razsirja EntityRecognizer. Napise regularni izraz, ga poveze v Presidio register, testira in vzdrzuje. Za ekipe za skladnost - ki redko kodirajo - je to tezka ovira. Vsaka sprememba formata zahteva inzenirja.

Zdravstveni inzenirji so zaposleni. Osredotoceni so na integracijo EHR in klinicne sisteme. Orodja za skladnost redko so na vrhu njihovih prioritet.

Postopek dela z vzorci brez kode

Vodeni pristop z vzorci odpravlja korak kodiranja.

Skladnostni uradnik odpre Ustvarjalec entitet po meri v spletni aplikaciji. Prilepi pet vzorcnih stevilk iz svojega sistema - na primer:

SVHS-0012345
SVHS-0987654
SVHS-1122334
SVHS-4455667
SVHS-8899001

Klikne Ustvari vzorec. UI prebere strukturo in vrne:

  • Vzorec: SVHS-\d{7}
  • Zaupanje: visoko
  • Predlagano ime: HOSPITAL-MRN
  • Predlagana zamenjava: [MRN]

Uradnik prilepi se pet vzorcev. Vzorec prestane. Shrani ga v HIPAA prednastavitev.

Od tega trenutka vsaka seja - spletna aplikacija, dodatek za Office, namizna aplikacija in API - zaznava ta format v standardnem prehodu PHI. Koda ni potrebna.

Opomba o GDPR raziskavah

Clen 89 GDPR zahteva psevdonimizacijo za raziskovalne podatkovne nize. Entitete po meri uvrstijo institucionalno specificne identifikatorje v obseg - s cimer se zapre vrzel, ki jo puscajo splosna orodja.

Kar pridobite

Ta postopek traja eno popoldne. Koda po meri traja tedne.

Skladnostni uradnik definira vzorec, ga testira in uvede. Brez zahtevka. Brez cakanja. Prednastavitev hrani entiteto po meri poleg standardnih 17 identifikatorjev Safe Harbor.

Ko se naslednja serija klinicnih zapiskov izvede, je pokritih vseh 18 vrst identifikatorjev. Safe Harbor je popoln.

Who built this

A small team of engineers and lawyers built this.

We ship from Europe and work in the open.

Our founder note spells out why we started.

Where to start

How the parts fit

A browser add-on cleans text inside Chrome.

A Word plug-in handles drafts in Office.

A small desktop tool works on whole folders.

An agent protocol link feeds large models safely.

All four share one core engine and one rule set.

Words from our team

We started this work after a lunch about cookies.

One friend kept getting odd ads on her phone.

We asked why a court file leaked through a draft.

We sketched the first build on a napkin that week.

By month three we had a tiny demo for a friend.

She used it on her first case the next day.

Common questions we hear

Can the tool read scanned PDFs? Yes, with OCR.

Does it work on long files? Yes, in small chunks.

Can I roll my own rule set? Yes, save it as a preset.

Does it run offline? The desktop build runs offline.

Do you keep my files? No, the cloud build wipes after each run.

Will it learn from my work? No, we never train on inputs.

A short tour of the workflow

Upload a file or paste a snippet of prose.

Pick the entities you want gone from the draft.

Choose a method: replace, mask, hash, encrypt, or redact.

Press run and watch the side panel show each hit.

Skim the result and tweak any rule that misfired.

Save the cleaned file or send it to a teammate.
