In the case of sites participating in ENEIDA, to avoid duplication of recording of the data by the responsible physician, the possibility of modifying the database will be proposed to the ENEIDA committee, including, in such a way that they are only visible to the investigators of this research project, the necessary variables that are not included in ENEIDA. In the event that this modification is not accepted by the ENEIDA committee, the study data will be recorded in an electronic database created specifically for this purpose.
