Caribbean cross-border healthcare

Healthcare in the Caribbean increasingly extends beyond national borders. Cross-border healthcare services such as patients referrals for treatment, laboratory services, and medicine monitoring are essential to deliver high-quality care. At the same time, digital health systems remain fragmented, limiting the ability to securely and effectively share information across countries. Caribbean Healthcare Interoperability Architecture is a open reference architecture that specifies the set of digital building blocks (e.g., health records, patient consent registries, medicine registries) that enable safe, scalable, and compatible cross-border healthcare.

Architecture principles

To enable cross-border healthcare in practice, we define a set of architecture principles that steer how the architecture is designed and applied. These principles translate real-world needs—such as safe data sharing, collaboration across countries, and efficient use of limited resources—into concrete design choices.

Reference Architecture

Based on the architecture principles, the reference architecture defines a set of digital building blocks that support real cross-border healthcare use cases. These building blocks represent concrete capabilities—such as identifying patients, exchanging data, managing consent, and sharing results—that are required to make these use cases work in practice.

Each building block can be implemented by different systems in different countries, but they follow common agreements on how data is structured and exchanged. This allows healthcare providers, laboratories, and regulators to collaborate across borders while using their own local systems.

By combining these building blocks, the reference architecture provides a practical foundation for interoperable healthcare in the Caribbean. It enables countries to gradually adopt and implement solutions that are compatible with each other, reducing fragmentation while supporting local needs and existing infrastructure.
