FHIR & HL7 Integration

Implement robust data pipelines using FHIR R4/R5, HL7, and IHE standards. We design interoperability layers that connect clinical systems reliably across diverse hospital environments.

Consultancy & Architecture

Strategic guidance on healthcare data architecture, interoperability frameworks, and national compliance programs (MedMij, VIPP, NEN7510, GDPR) from experienced practitioners.

Platform & Microservices

Design and deploy modular, cloud-native integration platforms using proven Smart-on-FHIR microservices patterns with event-driven architecture and infrastructure-as-code.

Data Modeling & Mapping

Build precise FHIR facades, common data models, and transformation layers on top of proprietary EMR systems. We turn complex clinical data structures into clean, usable resources.

Compliance & Security

Engineer ISO27001/NEN7510-compliant single-tenant environments with IAM, audit logging, E2EE storage, and annual external audit support. Patient data security is non-negotiable.

Patient-facing & eHealth

Deliver integrated patient portals, PROMs/PREMs collection systems, clinical dashboards, and branded eHealth initiatives — all driven by real-time EMR data.

Viscosity
+ Society

Just as viscosity describes how smoothly components flow together, Viscosiety is about making health data flow seamlessly through society.

We build technology and services that ensure data availability in healthcare, grounded in open standards and true interoperability. Beyond technology, Viscosiety is about people — creating a workplace and ecosystem where we do things the right way.

Our technology is built on the proven integration stack originally developed within Brightfish B.V. — a production-tested foundation for interoperable healthcare data solutions, refined across 75+ hospital integrations over 12+ years.

Open Standards First FHIR, HL7, IHE — we build on open, proven interoperability standards, not proprietary lock-in.
European Data Sovereignty Respect for GDPR, patient privacy, and European values is at the core of every solution we build.
Pragmatic Innovation We favor off-the-shelf open-source tools over reinvention — maximising reliability and longevity.
