The National Health Data Space (ENDS) is a Spanish initiative that provides an innovative infrastructure for using health data ethically and securely to advance research and innovation. It brings together public administrations and other participating organisations, encouraging cooperation while protecting the confidentiality of information in line with data protection requirements and the European framework for health data spaces.

ENDS aims to support better public health decisions, benefit patients, and enable research through responsible data use. Its website explains the organisation and governance of the initiative, its data protection approach, and the infrastructure and resources available. Visitors can explore the ENDS data catalogue and information on HealthDCAT-AP, as well as guidance and support related to data spaces.

The platform also presents developing use cases that demonstrate how data can create value in healthcare. These include identifying risk factors and early deterioration in people with COPD, monitoring antibiotic use and resistance trends, tracking international epidemic threats, and converting unstructured intensive care information into interoperable data for predictive analysis.
