Post-traumatic stress disorder (PTSD) is often thought of as a symptom of warfare, major catastrophes, and assault. It’s rarely considered in patients who survive a critical illness and stay in the intensive care unit (ICU). However, in a recent Johns Hopkins study, researchers found that nearly one-quarter of ICU survivors suffer from PTSD. They also identified possible triggers for PTSD and indicated a potential preventive strategy: having patients keep ICU diaries.
“PTSD can drastically impact a person’s ability to communicate and connect with others, truly interrupting their lives and preventing experiences of joy,” said Joe Bienvenu, MD, associate professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine. “This is why our findings are important and why it’s so critical that we continue to research ways to prevent PTSD.”
Common risk factors for PTSD included being diagnosed with a psychological problem, such as anxiety or depression, before coming to the ICU, the researchers found. Another risk factor was receiving large amounts of sedation medication while in the ICU. Additionally, patients that reported having frightening memories of being in the ICU have a higher risk of PTSD.
The researchers also looked at the best ways to prevent PTSD. The solution that seemed most effective was an ICU diary, a notebook that allows clinicians and family members to write daily messages about what is happening to the patient.
“Diaries seem to help patients process their experience and formulate more accurate memories of their time in the ICU. They provide patients with a tool to better understand their experience in the ICU through the words of their loved ones and caregivers,” said Bienvenu.
