From the NY Times a video about PTSD after being a patient in ICU. Makes sense to me, but something I never thought about (but then again I have never worked ICU). The end of video discusses how some nurses create a diary for patients to take home to help piece together their ICU stay. Not sure how much time that takes, or what liabilities might arise from a diary, but it is interesting idea.
