2029 is closer than a replacement programme
Three dates decide it: 2027, 2029, 2031. A provider has two routes. Replace the record system, or put a conforming layer above it.
- Dates from the Regulation
- The overlay route, stated
- No vendor comparison

patient access and interoperability
Layer, not replacement
a conforming route without migration
Why this became a budget question
Regulation (EU) 2025/327 entered into force on 26 March 2025 and the preparatory period runs to 2027. What changed is who pays. The obligations attach to the provider and to the systems the provider already runs, not to the ministry that negotiated them. A record system installed today is in scope from 2031. The question is no longer whether to act, but whether the action is a replacement programme or a layer.
What applies, and from when
Per obligation. The dates are the Regulation's, not ours.
- 26 March 2025
- Entry into force. Preparatory period begins. No obligation attaches to a provider yet.
- 26 March 2027
- Member States designate authorities. The Commission sets requirements for healthcare ICT systems through secondary legislation.
- 26 March 2029: primary use
- Patient access and interoperability apply to essential patient data, electronic prescriptions and dispensations, and to the EHR systems holding them.
- 26 March 2029: secondary use
- Chapter IV: data permits, the national catalogue, opt-out, statistical requests, through Health Data Access Bodies.
- 26 March 2031
- Imaging, test results and discharge reports. Chapter III applies to systems already deployed before this date. Sensitive categories enter secondary use.
- 26 March 2035
- Third countries with adequate standards may join HealthData@EU.
- What a provider is accountable for
- Patient access to the listed categories, interoperability of the systems holding them, and the record of who accessed what.
- What a provider is not accountable for
- The permit process itself, which sits with the Health Data Access Body.
Replacement or a layer
What each route has to deliver. Two routes, never named vendors.
| Requirement | Replace the record system | Add a conforming layer above it |
|---|---|---|
| Patient access to the listed data | ||
| Interoperability of the holding system | ||
| Structured export of the listed categories | ||
| Audit of access | ||
| Clinical risk during transition | ||
| Time to first compliance step | ||
| Cost carrier | ||
| What stays with your existing system |
In force: applies today and can be evidenced. In progress: under way and dated. Readiness: the position is prepared and the market opens next.
What a provider asks first
Is our hospital in scope?
Do we have to replace our information system?
What if our system exposes nothing?
Who enforces it?
What should we do in 2026?
Monthly briefing
The signal, once a month.
What changed in European health data, what we shipped, and what it means for a provider. Nothing else.
