E-SATIS NATIONAL SURVEY, MEASURING PATIENT SATISFACTION AND EXPERIENCE.: Since 2015, the French National Health Authority has been managing and rolling out the national programme for measuring patient satisfaction and experience, called 'e-Satis'. Thanks to this evaluation, it has produced, for all participating healthcare facilities, detailed and continuous results, in order to guide the improvement of the quality of practices and the organisation of care. The National Health Authority must now look to consolidate the programme, notably through greater patient participation and the appropriation of the results by professionals.
