What Programma-Twiin does

Programma-Twiin is the designated national healthcare interoperability framework for the Netherlands, executed by VZVZ (Vereniging van Zorgaanbieders voor Zorgcommunicatie) and based in Den Haag. It is not an IT vendor or infrastructure operator: its core product is the Twiin Afsprakenstelsel, a codified body of legal, organisational, semantic, and technical agreements that governs how Dutch healthcare providers exchange health data at local, regional, and national levels. The framework builds on FHIR (HL7), IHE mCSD, and the NEN 7510/7512/7513 information-security and BgZ (NEN 7540) standards, and specifies trust, routing, privacy, security, logging, and communication patterns that are supplier- and infrastructure-independent.

The product surface centres on three layers: a normative agreement framework with major releases (current version 1.4.0); validated technical agreements such as TA Notified Pull (FHIR-based pull pattern for the Basisgegevensset Zorg) and TA Routering (IHE mCSD-based routing); and validated infrastructure nodes called Gevalideerde Twiin Knooppunten (GtK's) — the first being ChipSoft's Zorgplatform and NEXUS Cloud Connect. Care applications include landelijke BgZ exchange (patient summary transfer) and Beeldbeschikbaarheid (national radiology image availability). Twiin is governed by an Architectuurraad and a Privacy- en Securityraad, with stakeholder representation from NVZ, NFU, ZKN, ZN, and VWS.

Twiin is publicly funded and does not charge healthcare providers or suppliers for participation. Engagement is driven through three complementary motions: direct onboarding of providers via the Twiin Deelnemersovereenkomst guided by a Groeimodel (growth model); a channel of Regionale Samenwerkingsorganisaties (RSOs) acting as Twiin Dienstverleners; and a community/event-led motion including expertsessies, projectathons, and Twiin Dag. In March 2025 the Dutch Minister of Health designated Twiin as the Landelijk Vertrouwensstelsel (National Trust Framework), and the program is transitioning toward public governance under the future Gezondheidsdata-autoriteit (GDA) over the next 3-4 years.

Core offering

Programma-Twiin provides the Twiin Afsprakenstelsel — a national framework of juridical, organisational, semantic, and technical agreements governing the exchange of health data across Dutch healthcare organisations. It is not an IT system or infrastructure itself, but specifies trust, routing, security, privacy, and communication patterns built on FHIR and IHE mCSD standards, validated through Gevalideerde Twiin Knooppunten (GtK's). Care applications such as BgZ (Basisgegevensset Zorg) and Beeldbeschikbaarheid are enabled on top of the framework, and healthcare providers participate by signing the Twiin Deelnemersovereenkomst.

Product overview

Programma-Twiin is a national healthcare data exchange framework (not an IT vendor) that provides a unified agreement system for secure and reliable health data exchange in the Netherlands. The core product is the Twiin Afsprakenstelsel (Twiin Agreement Framework), which contains all agreements needed for data exchange at local, regional, and national levels. The framework centers on validated infrastructure nodes called Gevalideerde Twiin Knooppunten (GtK's), exemplified by platforms like ChipSoft Zorgplatform and NEXUS Cloud Connect. Key healthcare applications include BgZ (Basisgegevensset Zorg) for basic patient data exchange and Beeldbeschikbaarheid for radiology image sharing. Technical agreements like TA Notified Pull (FHIR-based exchange pattern) and TA Routering (IHE mCSD profile for routing) enable interoperability. The framework also includes Generieke Functies for consent, localization, identification/authentication, and authorization. Supporting services include a Growth Model for stepwise validation and self-assessment tools. Governance is provided through a Privacy and Security Council and Architecture Council.

Functional benefit

Products and services

• Twiin Afsprakenstelsel (Twiin Agreement Framework) The foundational agreement framework containing all necessary juridical, organisational, semantic, and technical agreements for exchanging health data at local, regional, and national levels. Aligned with current legislation and standards, it provides the framework within which Dutch healthcare organisations can exchange health data with reliability and confidentiality ensured. Forms the foundation for a National Trust Framework (Landelijk Vertrouwensstelsel).
• BgZ - Basisgegevensset Zorg (Basic Healthcare Data Set) The minimum set of important patient data relevant to all healthcare providers, not limited to one specialization, disease pattern, or professional group. Used for transfer of care between different healthcare institutions, enabling all involved caregivers to have a patient summary with previous treatments from different institutions.
• Beeldbeschikbaarheid (Image Availability) Enables radiological images and associated reports to be reliably and safely requested and shared nationally between healthcare institutions. Provides a chronological overview of all radiological examinations of a patient regardless of where they were performed. Currently in pilot phase.
• TA Notified Pull (Technische Afspraak Uitwisselpatroon Notified Pull) Technical agreement specifying the FHIR-based Notified Pull exchange pattern. A healthcare provider receives a notification that a BgZ can be retrieved from the sending party, then retrieves it on demand. Ensures data is current when requested, supports data minimisation, and provides better security than active push methods, with OAuth 2.0 access control and audit logging.
• TA Routering (Technical Agreement Routing) Technical agreement specifying mechanisms for routing notifications, referrals, and orders received from other organisations internally, using the IHE mCSD profile. Routing occurs based on structured searching in a directory, enabling notifications to reach the correct care service, sub-organisation, care professional, or location within a receiving organisation.
• Gevalideerde Twiin Knooppunten (GtK's) - Validated Twiin Knotspoints Validated platforms that play a key role in safe and uniform sharing of medical data. GtK's promote collaboration between healthcare institutions, accelerate diagnoses, and contribute to higher care quality and patient safety. First validated GtK's are ChipSoft Zorgplatform and NEXUS Cloud Connect. GtK suppliers build and validate their own nodes; healthcare providers then connect and validate as Twiin Deelnemers.
• Twiin Groeimodel (Growth Model) A growth model developed by Twiin that supports Twiin Participants in step-by-step meeting the requirements of the Twiin Agreement Framework and working towards validation. Provides concrete, achievable intermediate steps for joining Twiin, complemented by a self-scan and supported by Twiin Dienstverleners.
