Healthcare Software Architecture Guide

Healthcare software consists of many systems that need to communicate with each other: HBYS, laboratory, imaging, external institutions, and regulatory systems. The consistent and sustainable communication of these systems is the core subject of healthcare software architecture. This guide addresses the topic in a comprehensible framework for technical teams and decision-makers.

Why is healthcare software architecture important?

A well-designed architecture allows systems to adapt to growth, facilitates integrations, and keeps maintenance costs predictable. Poor architecture can lead to technical debt and integration challenges over time.

Integration standards: HL7 and FHIR

Standards have been developed for healthcare systems to communicate in a common language:

• HL7: A widely used family of standards for data exchange between healthcare information systems.
• FHIR: Offers a modern, web-based, and more flexible approach to data sharing.

The choice of which standard to use is evaluated based on integration needs, counterpart systems, and existing infrastructure.

Data model and interoperability

Interoperability is the ability of different systems to share and interpret data consistently. Common terminology sets and standardized data models facilitate achieving this goal.

Security and data protection

Since health data is sensitive, security and KVKK requirements should be a layer designed from the outset, not added later. Authorization, access logs, and data encryption are parts of this layer.

Scalability and sustainability

A modular and loosely coupled architecture allows systems to be developed and updated independently of each other. This approach supports sustainability in the long term.
