ehr-sieve
Status: pre-release. This version (0.0.1) contains no functionality yet. The first working release is planned as 1.0.0.
ehr-sieve is a Python library for minimizing protected health information (PHI) in FHIR R4 and other EHR JSON inside the provider's environment, before data is shared with analytics, AI or research partners.
What it will do
- Find PHI by structure, not just field names. It recognizes FHIR datatypes (Identifier, HumanName, ContactPoint, Address, Reference, Attachment, Narrative) wherever they appear, including inside extensions and polymorphic
value[x]fields. - Apply a declarative, versioned policy. Each field is kept, dropped, tokenized, or generalized (birth year, three-digit ZIP with restricted-ZIP handling, ages over 89 capped).
- Deny by default. Fields the policy doesn't list are dropped or reported, so a new EHR field can't slip through unreviewed.
- Tokenize with keyed HMAC. The provider holds the key and the token-to-identity crosswalk. A partner receiving tokens can't reverse them.
- Report shapes, never values. A scanner lists every field path in a dataset with counts, so a policy can be built without anyone outside seeing PHI.
- Ship reference profiles, including a minimized Limited Data Set profile.
