Public knowledge base

Healthcare architecture resources designed to support real decisions.

Explore subject collections, navigators, comparative atlases, assessment tools and working proposals without treating the library as one flat list.

Featured reference

UK Secondary Care Integration Reference Atlas

A capability-led comparison of the integration mechanisms and data flows that connect secondary care with national, primary-care and shared-record services in England, Wales, Scotland and Northern Ireland. It also compares the four nations with the emerging EHDS architecture without treating architectural alignment as legal compliance.

Why it exists

Standards labels alone do not show how clinical information actually travels. The Atlas compares operational integration surfaces and evidence quality instead.
