How HealthTAG connects data and checks access
HealthTAG connects existing HIS data through FHIR, links patient identities, checks authorization, and records consent and access events.
Data Connect
Connect an existing HIS to the hospital FHIR system through a hospital-managed script or HealthTAG FHIR Transformer.
How systems connect →Patient identity linkage
Link hospital-local patient identifiers to a common identity reference so records can be matched to the same person.
Follow the exchange flow →Consent and Authorization
Record the patient's consent, then evaluate each access request separately.
Consent and access →Audit and Provenance
Record consent and access events for later review while keeping the hospital source of each clinical record clear.
Audit and data sources →Information by role

HealthTAG PHR
View permitted health information in one place
HealthTAG PHR presents the health information available and permitted for each patient. Hospitals continue to store and steward the original clinical records in their source systems.
Founded from clinical work
HealthTAG began with a problem seen in patient care
Health records may exist in several systems but still be difficult to use when a patient needs care. HealthTAG starts product decisions with one question: will this improve patient care?
