The Data Support, Processing, and Analysis Division (DATA) provides support to the entire agency in the areas of data processing and analysis. The division’s main activities include data management, statistical analysis, geomatics, metrology, and IT application support. The division also oversees syndromic surveillance and supports the design, implementation, and operation of surveys.

The data used comes from:

• specific surveillance systems

• a syndromic surveillance system (SurSaUD®)

• surveys (epidemiological and/or behavioral)

• medical-administrative databases, particularly from the National Health Data System (SNDS)

• reference data (INSEE, etc.), meteorological data, etc.

DATA comprises approximately 50 staff members and is organized into three units:

• the “Applications, Big Data, and Syndromic Surveillance” unit

• the “Support and Methods for Studies and Investigations in the Field of Surveillance” unit

• the “Surveys” unit.

The department oversees two programs:

• Syndromic surveillance

• Modernization of data collection, analysis, and reporting

In particular, it is responsible for:

• Conducting the Santé publique France Barometer, a tool for steering public action in the health sector. This survey tracks changes in the health knowledge, behaviors, and attitudes of the French population, thereby serving as a measure of the effects of public policies on major health issues. This telephone survey is based on a random sample.

• Overseeing syndromic surveillance, whose scientific objectives are to detect an unexpected health event, estimate the impact of an environmental or societal event, monitor diseases outside of any specific event, and detect a predefined health event—such as a seasonal epidemic—at an early stage, while measuring its impact and consequences. This surveillance is based on: - data from hospital emergency departments participating in the OSCOUR® network (Organization for Coordinated Emergency Surveillance), - data from SOS Médecins associations, - mortality data from computerized civil registry systems transmitted by INSEE, - electronic death certificate data

• To manage the agency’s cartographic observatory (Géodes), enabling the visualization of indicators useful for decision-making and action in public health. The Géodes observatory responds to a strong commitment to transparency and modernity by providing simplified, open access to numerous health indicators. Thanks to this platform, which is accessible to all, users can:

• Access more than 300 indicators covering 40 topics

• Compare regional and national indicators

• View technical details for each indicator: source, update period, etc.

• Download maps and data and share them on social media

• Import data into Geodes and compare it with that of Santé publique France.
