MedMij

What MedMij does

MedMij (legal entity Stichting MedMij) is the Dutch national framework and certification authority for secure health data exchange between patients and healthcare providers via Personal Health Environments (PGOs). Established as a program in 2016 by Patiëntenfederatie Nederland and the Informatieberaad Zorg, it became an independent foundation in 2018 and is headquartered in The Hague. Its mission is operationalized through the Wegiz legal mandate, which requires Dutch healthcare providers to make patient data digitally available through MedMij-certified systems, and the organization is fully financed by the Dutch Ministry of Health, Welfare and Sport (VWS) since 2025, with prior co-funding from Zorgverzekeraars Nederland (ZN).

The core offering consists of the MedMij Afsprakenstelsel (a comprehensive set of legal, technical, organizational, and security agreements), the registered MedMij certification label, and standardized gegevensdiensten (data services) for specific data types such as medications, lab results, vaccinations, appointments, and documents. The technical architecture is built on HL7 FHIR as the interoperability standard, layered with Dutch zibs information building blocks, and operationalized through an all-to-all network model in which any certified PGO vendor (DVP) can exchange data with any certified healthcare IT system (DVA). Security is enforced through mandatory NEN 7510 certification (annual audits and pentests), DigiD-based authentication, and integration with the national LSP exchange infrastructure. Adoption is broad: 82% of GPs, 85% of hospitals, and 50% of clinics/GGZ institutions are connected, with 16-18 PGO vendors and 10+ DVAs holding the MedMij label, and over 1,000,000 patient data requests processed via PGO as of October 2023.

MedMij does not charge fees for certification or use of the framework. Its GTM is essentially a self-service and channel model: ICT suppliers onboard via the MedMij Toolkit, qualify through Nictiz (qualification testing) and Vecozo (acceptance testing), and connect providers through their DVA. The foundation serves three primary segments — Dutch citizens (PGO users), healthcare providers (GPs, hospitals, clinics, GGZ, long-term care, birth care, ambulance), and ICT suppliers (PGO vendors and healthcare IT integrators) — with recent expansion into medical imaging (2026) and occupational health (PGO & Work, 2026).

Core offering

Stichting MedMij operates the Dutch national standards framework (MedMij Afsprakenstelsel) and certification mark (MedMij Label) that govern secure health data exchange between citizens and healthcare providers via Personal Health Environments (PGO). Certified participants (PGO vendors and healthcare IT suppliers) must meet FHIR-based technical, legal, organizational and NEN 7510 information security requirements to display the MedMij Label.

Product overview

MedMij operates as a framework and certification body rather than a direct product vendor. The core offering consists of the MedMij Afsprakenstelsel (MedMij Framework) - a comprehensive set of agreements governing secure health data exchange - and the MedMij-label certification that verifies PGO providers and ICT suppliers meet these standards. The MedMij-gegevensdiensten (Data Services) layer provides standardized specifications for exchanging specific types of health data (laboratory results, medications, vaccinations, documents, etc.). Supporting tools include the MedMij Toolkit for onboarding new participants, the MedMij Register for viewing certified organizations, and MedCom for participant communication. Verbind.MedMij provides a QR-code system for simplified patient-provider connection. MedMij does not develop PGO applications itself but certifies third-party PGO providers operating within the ecosystem.

• VZVZ / LSP+: Operator of the Dutch national healthcare exchange point (LSP/LSP+); an existing DVA participant in the MedMij network providing complementary connectivity infrastructure for health data exchange.
• ELGA (Austrian ELGA GmbH): Austria's national electronic health record infrastructure operator, federally mandated, that provides citizens access to their health data — closest international peer in role and architecture.

Broad incumbents

• Sequoia Project: US non-profit advancing health information exchange, parent of Carequality; comparable in operating as an independent standards/certification organization for national health-data exchange.
• NHS App / NHS Digital: UK government-built patient-facing health-data platform with similar citizen/patient goal and national mandate; broader but comparable in giving patients access to interoperable records.

Emerging players

• Health Gorilla: US health information network and FHIR-based interoperability platform enabling clinical data exchange between providers, payers, and patients — comparable technology stack and use cases.
