OIZ

What OIZ does

OIZ (vereniging OIZ, branchevereniging voor ICT in de zorg) is the Dutch trade association for healthcare ICT suppliers, structured as a membership-based nonprofit (branchevereniging) headquartered in Utrecht. It represents more than fifty member organizations, including dominant electronic health record vendors (ChipSoft, Epic, Oracle/Cerner), Dutch infrastructure and clinical software providers (Nedap, KPN Health, Sectra, Philips), and a long tail of smaller niche suppliers and startups. The association convenes working groups on topics such as interoperability (Wegiz, HL7/FHIR), medical device regulation (MDR), the European Health Data Space (EHDS), the Data Act, and the AI Act, and it is a member of the European industry umbrella COCIR, extending its reach into EU-level policy.

The core product is collective representation and coordination services: regulatory advocacy, sector-wide standardization, knowledge-sharing events, and member communities (including an Innovators track and the OIZ Startup program for early-stage suppliers). OIZ does not build or sell proprietary technology; its outputs are policy positions, joint consultations, working-group deliverables, and convening platforms. Revenue is generated primarily through annual membership dues, which scale with member size from €810.90 to €8,313 per year, supplemented by event and program-related income. The secretariat is intentionally lean at approximately five employees, led by director Marcel Smeets, with a board chaired since October 2025 by Vincent van den Berg of ChipSoft. In 2024, OIZ formalized a joint foundation called SILIZO with NedXis to consolidate cross-association work on healthcare ICT standards and policy.

Expansion highlights5 records

Broad incumbents

• HIMSS: Global healthcare information and technology membership organization; comparable as a much larger incumbent running member advocacy, education, events and policy work across the healthcare IT ecosystem.
• ECHAlliance (European Connected Health Alliance): Multi-stakeholder European network connecting digital health ecosystems, organizations and governments; comparable as a broader membership-driven advocacy and networking platform overlapping with OIZ's European healthcare-IT mandate.
• CHIME: US professional association for healthcare CIOs and senior IT leaders; comparable as a membership body serving senior healthcare IT decision-makers with advocacy, education and networking, though skewed toward provider-side rather than supplier-side.
• COCIR: European umbrella trade association for healthcare IT, radiotherapy and electromedicine suppliers; comparable because it provides the same supplier-advocacy and standardization function at the EU level that OIZ provides nationally — OIZ is itself a participating member via FG Europa.

Others

• Nictiz: Dutch expertise center for electronic patient records and health data standards (NEN, HL7, FHIR, SNOMED); comparable as a Dutch healthcare IT ecosystem stakeholder that OIZ works with on standardization, though structured as an expertise center rather than a supplier trade association.
• HL7 Nederland: Dutch national affiliate promoting HL7 family health data exchange standards; comparable as a Dutch healthcare IT standards organization that is itself an OIZ member and co-organizes the annual IHE/HL7 congress with OIZ.
• IHE Nederland: Dutch affiliate of Integrating the Healthcare Enterprise promoting healthcare interoperability standards; comparable as a Dutch healthcare IT standards body that is an OIZ member, co-organizes the annual IHE/HL7 NL congress, and whose previous chair (van den Berg) is now OIZ board chair.

Regional players

• Digital Health Canada: Canadian membership association advancing digital health through advocacy, education and networking; comparable as a country-level healthcare-IT membership organization but serving a different national market.
• GMDS (Deutsche Gesellschaft für Medizinische Informatik, Biometrie und Epidemiologie): German scientific-membership association for medical informatics, biometry and epidemiology; comparable as a national-level membership organization driving healthcare IT standards and policy debate in a neighboring market.

Direct peers

• NedXis: Dutch trade association for ICT suppliers in primary care (eerstelijnszorg); most direct peer because it operates the same membership-based supplier-advocacy model in a closely adjacent Dutch healthcare segment and jointly founded SILIZO with OIZ in 2024.
