Netherlands Zorginzage Implementation Guide

Overview

The Zorginzage (Healthcare Viewing) Implementation Guide enables healthcare professionals to securely view patient data across organizational boundaries using FHIR, OAuth 2.0, and decentralized trust infrastructure.

Key Features

  • Secure Access: Healthcare professionals view data from other organizations with proper authorization
  • Patient Control: Patients control access through consent management
  • Standards-Based: FHIR R4, OAuth 2.0, Nuts decentralized network
  • Pull Architecture: Data retrieved on-demand, not pushed
  • Comprehensive Auditing: NEN7513 compliant logging

Quick Start

  1. ​Introduction - Scope, use cases, and key concepts
  2. ​Actors & Transactions - System roles and interactions
  3. ​Process Flow - Publishing and consulting workflows
  4. ​Security - Authentication and authorization
  5. ​Specifications - Technical implementation details

Core Concepts

Authorization Records

Machine-readable credentials specifying who can access what data for which patient and purpose.

Care Applications

Domain-specific profiles (maternity care, medication overview, etc.) with their own governance and access policies.

Actors

  • Data Holder: Maintains and provides access to patient data
  • Consumer: Retrieves patient data on behalf of users
  • Authorization Registry: Stores and syncs authorization records
  • OAuth Server: Issues access tokens

Standards Used

International: FHIR R4, OAuth 2.0, JWT, mTLS, Verifiable Credentials

Dutch National: ZIBs (Healthcare Information Building Blocks), Nictiz FHIR profiles, Nuts network, UZI/IRMA authentication, NEN7513 audit logging

Implementation

Systems must implement:

  • Authorization record creation/validation
  • User authentication (UZI or IRMA)
  • OAuth 2.0 token flow
  • FHIR R4 API
  • Mutual TLS
  • NEN7513 audit logging
