Charged by law to gather, organize and make available the data of the expanded National Health Data System (SNDS) and to promote innovation in the use of health data, the HDH has set itself several strategic directions:

• Reduce access times to healthcare data and multiply impactful projects;
• Make available data from the SNDS main database, enrich it and facilitate its reuse;
• Strengthen the connections of the HDH to players in the ecosystem;
• Be attentive to civil society and co-construct a health data culture.

The HDH supports projects by providing resources tailored to their needs and offering several services:

• A one-stop shop for requests for access to data from the National Health Data System (healthcare consumption in the city, hospitalizations, biological examinations, ...);
• A catalog to make priority data available to the community (historical SNDS, cohorts, registries, hospital data, ...);
• A secure technological platform for data storage, calculation, reconciliation and analysis capabilities;
• A networkto connect all the players in the ecosystem;
• Training and educational kits to provide useful resources for all audiences (project developers, citizens, researchers...). To access and reuse third-party data, you generally need to comply with a number of formalities, the HDH helps you identify the appropriate approach and its steps.

• At the time of reflection on the potential interest in using SNDS data;
• At the time of application to access the data.

The HDH offers, depending on the project, complete end-to-end support: human, technological and financial resources.
