Aftercare is a rapidly developing area and it is necessary to further investigate this important topic. Therefore, the investigators want to describe the current level of aftercare with a new mapping of activities in all Danish ICUs. Hereby, the investigators hope to create a better and up-to-date foundation for further development within Danish aftercare. Furthermore, the investigators wish to research on the clinician-experienced (the participants) attitude towards and limitations for aftercare activities, in order to discuss directions for future development.
