HealthTAG / Company overview

Health data belongs to the patient

Patients control consent and use. Hospitals store and steward clinical records in their source systems. HealthTAG provides trust and interoperability infrastructure for authorized exchange.

OUR VISION

Your data. Your consent. One connected Thailand.

We are working toward a Thailand where each person controls consent and use of their health data. Records can connect across the country, and that data can support better care with safeguards, transparency, and an audit trail.

OUR MISSION

Build trusted health data infrastructure for Thailand

Our mission is to keep clinical records in hospital source systems and allow their authorized use according to the data owner's consent. Open standards connect hospitals, universities, public agencies, and industry. This can support better care and medical AI in the future.

Patient: Owns their health data and controls consent and use.
Hospital: Stores and stewards the clinical record in its source systems.
HealthTAG: Provides trust and interoperability infrastructure for authorized exchange.

Six values that guide our work

These values guide HealthTAG product decisions, technical boundaries, and work with partners.

01
Patient Sovereignty
Health data belongs to the patient, not to a system. Consent must be explicit, limited in scope and time, auditable, and revocable. Hospitals store and steward clinical records in their source systems.
02
Trust Before Intelligence
Before health data supports AI, it must be possible to verify where the data came from, who used it, when it was used, and under what right.
03
Data Stays at Source
HealthTAG does not centralize the country's clinical records. Hospitals continue to store and steward their records while the infrastructure connects authorized access.
04
Open Standards, Real Interoperability
We use open standards such as HL7 FHIR so systems from different vendors can connect without replacing the core HIS or creating unnecessary lock-in.
05
Clinically Grounded
Founded by a physician, HealthTAG starts with a practical question: will this improve care for the patient? We choose technology only after the clinical need is clear.
06
Ecosystem, Not Ego
National health data infrastructure requires accountable work with hospitals, universities, the public sector, industry, and technology partners. No organization can build it alone.

CLINICALLY GROUNDED

Dechowat Promda, M.D.

Founder & CEO, HealthTAG

Dr. Dechowat founded HealthTAG after seeing a recurring problem in patient care: one patient's records were scattered across systems that did not connect, with no shared infrastructure for moving data correctly and with permission. He remains in clinical practice while leading the team, keeping product decisions tied to the realities of care.
