The actions under this thematic section have as objectives to provide support for the development of a governance model and rules on access to health data for secondary use and for the development, deployment and operation of infrastructures and IT systems that will enable access to health data for secondary use, i.e. for research and development, policy-making and regulatory activities. The EHDS supports research and development on new preventive strategies, treatments, medicines, medical devices and better outcomes, and it should support policy-makers and regulators to make evidence-based decisions, ensuring in full the preservation of the privacy and the personal data of citizens. Furthermore, and embracing the ‘One Health’ approach, the set-up of the European Climate and Health Observatory aims at supporting adaptation plans and measures in Member States related to climate change and health. The expected results are the setting of the foundations of a common EHDS, both at national and European level with due respect to all aspects related to the processing of data. The expected results of the European Climate and Health Observatory are the establishment of a knowledge base for better-informed Union policy-making on climate change-related health effects. Within this thematic area, the Commission plans to launch open procedures for a service contract for support services in the field of development, deployment and operation of infrastructures and IT systems enabling access to health data for secondary use.
