## Abstract

This article presents the design and implementation of a digital health technology architecture focused on healthcare regulation in Brazil's National Health System (SUS). The objective was to develop an architectural model capable of optimizing resource allocation, increasing transparency, and integrating health information from different levels of care, with a focus on reducing inequalities in access.

Methodologically, a transdisciplinary applied research approach based on action research was adopted, with iterative development cycles in accordance with agile methodologies. The architecture was implemented in the states of Rio Grande do Norte, Espírito Santo, and Mato Grosso, respecting regional specificities and integrating international interoperability standards, as well as architectural principles and software engineering.

The results point to flexibility, interoperability, real-time monitoring, queue management, and transparency, including direct access for control bodies and process auditability.

It can be concluded that the proposed architecture represents a significant advance for equity in access and could serve as a basis for solutions on a national and international scale.
