For many people their first experience with an Intensive Care Unit may be when they find themselves or a loved one critically ill or injured. It can be an intensely stressful and scary time. It is not uncommon for those who experience critical illness or injury to later develop sleep disturbances such as insomnia, vivid dreams, and even nightmares. Many of the symptoms that former ICU patients experience are consistent with post-traumatic stress disorder and are included within the syndrome we are now calling Post Intensive Care Syndrome or PICS. Many interventions are being explored that address post-ICU recovery, however one intervention has already proven its usefulness in combating PTSD in post-ICU patients - ICU diaries.
