The investigators compared the efficacy of the ICU diary, prospectively written by third-parties during the patient's intensive care course, versus education-alone, on reducing acute PTSD symptoms after discharge. Patients with an ICU stay greater than 72 hours, and who were intubated and mechanically ventilated over 24 hours, were recruited and randomized to either receive a diary at bedside with psychoeducation, or psychoeducation alone. Intervention patients received their ICU diary within the first week of admission into the intensive care unit. Psychometric testing with IES-R, PHQ-8, HADS and GAD-7 was conducted at weeks 4, 12, and 24 after ICU discharge.
