HealthTAG connects existing hospital systems through HL7 FHIR R4, links patient identities, checks access, and records consent and access events. Patients own their health data. Hospitals continue to store and steward clinical records in their source systems.
Hospital systems retain the clinical records. An identity linkage service connects patient identifiers, an authorization service checks access requests, and blockchain records consent and access events.
Moves selected data from an existing HIS into a hospital-stewarded HL7 FHIR R4 system. Hospital IT can use its own integration script or HealthTAG FHIR Transformer.
Links the patient identifier used by each hospital to a common identity reference, while clinical records remain in hospital systems.
Records the patient's consent, while the authorization service evaluates each access request before the source system returns permitted information.
Records consent and access events for later review and keeps the hospital source of the clinical record clear. Clinical records are not stored on blockchain.
The hospital keeps custody of its records and chooses the ingestion path that fits its IT capability. Siriraj uses a hospital-developed script. Khian Sa uses HealthTAG FHIR Transformer for four confirmed FHIR resources.
A hospital may use an IT-managed script or HealthTAG FHIR Transformer. The current hospital-side architecture separates FHIR storage, API protection, identity linkage, and authorization.

Siriraj published the 5G Smart Hospital programme, ETDA recorded HealthTAG's Digital Service Sandbox participation, and APICTA named Healthtag as the 2022 Cross Category: Start-Up winner.
The confirmed deployments use hospital-managed scripts, HealthTAG FHIR Transformer, and a multi-institution network model.
Siriraj announced the Siriraj World Class 5G Smart Hospital with nine subprojects, including Permission based blockchain for personal health record. HealthTAG participated in the PHR subproject and Siriraj IT uses its own HIS-to-FHIR script.
APICTA's official winner list names Healthtag of Thailand and BLOCKCHAIN-BASED PHR & HEALTH DATA MANAGEMENT PLATFORM as the Cross Category: Start-Up winner.
ETDA lists the HealthTAG service in its Digital Service Sandbox and records its exit after meeting the defined test goals and indicators. The test covered three hospitals in the Siriraj network.
