The main objectives of the registry were to facilitate the collection of clinical data of interest for clinical care practice, as well as to carry out collaborative studies using clinical data and biological samples. In its 15 years of existence, ENEIDA has evolved in many aspects, from its content or technological support to the number of participating centres, to become one of the reference registries for the study and care of patients with inflammatory bowel disease, with a continuous and high quality scientific production that has positioned it as an example of collaborative scientific exploitation at an international level. This article reviews the objectives, design, structural characteristics, monitoring and scientific exploitation of the ENEIDA registry.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/ENEIDAEnfermedad inflamatoria intestinalGETECCUInflammatory bowel diseaseRegistroRegistryGene-Environment InteractionHumansInflammatory Bowel DiseasesRegistriesSpainresearch article32674882open access10.1016/j.gastrohep.2020.05.007https://doi.org/10.1016/j.gastrohep.2020.05.007
