Critical care consists of providing an intense and intricate level of medical care , to people who have life-threatening injuries and illnesses. Patients are often confronted with their own mortality while receiving these treatments. Some medical interventions can also leave patients unable to communicate or orient themselves to hospital staff and their surroundings. Therefore, patients are at high risk of developing post-traumatic stress disorder (PTSD). There are current post intensive care unit (ICU), PTSD treatments available, however research shows that incorporating ICU diaries as an intervention can reduce PTSD rates after discharge.
