Nearly one-quarter of intensive care unit survivors have post-traumatic stress disorder; diaries could be successful prevention tool. Through a systematic literature review, the research team looked at 40 studies of 36 unique patient cohorts with a total of more than 3,000 patients who survived a critical illness and ICU stay. The researchers excluded patients who had suffered a trauma, such as a car crash, or brain injury, because those patients’ cognitive and psychological outcomes can be affected by the injury itself, rather than the critical illness/ICU stay. They found that the prevalence of PTSD in the studies ranged from 10 to 60 percent.

John Hopkins Medicine: The researchers found that 66 of the 186 patients (35 percent) had clinically significant symptoms of PTSD, with the greatest apparent onset occurring by the initial, three-month follow-up visit. Sixty-two percent of the survivors who developed PTSD still had symptoms at their two-year visit. Half of this same group was taking psychiatric medications, and 40 percent had seen a psychiatrist in the two years since being hospitalized with ALI.

Main results: Interviews were obtained for family members of 284 (62%) of the 459 eligible patients. Post-traumatic stress symptoms consistent with a moderate to major risk of PTSD were found in 94 (33.1%) family members. Higher rates were noted among family members who felt information was incomplete in the ICU (48.4%), who shared in decision making (47.8%), whose relative died in the ICU (50%), whose relative died after end-of-life decisions (60%), and who shared in end-of-life decisions (81.8%). Severe post-traumatic stress reaction was associated with increased rates of anxiety and depression and decreased quality of life. Conclusion: Post-traumatic stress reaction consistent with a high risk of PTSD is common in family members of ICU patients and is the rule among those who share in end-of-life decisions.
