I thought this was fascinating...maybe it's because I'm a twisty ICU nurse and enjoy reading these types of articles. Patients in the ICU sometimes end up going, well, for lack of a better word: crazy! These poor people are so ill and have many invasive medical procedures or treatments being performed. We refer to this "crazy" state as ICU delirium. This article is all about how ICU patients and their experiences after leaving the hospital. Hope it's an interesting read for you!
