Can a simple checklist forecast PTSD after critical illness?

This study asks whether routine medical data can predict which survivors of an emergency intensive care unit (EICU) stay will develop post-traumatic stress disorder (PTSD) one month after leaving the hospital. Researchers will follow about 800 adult patients, collecting details from their emergency department and ICU care—like vital signs, treatments, and severity of illness—and then assess them for PTSD using a standard diagnostic interview. The goal is to build a risk prediction model that helps doctors identify high-risk patients early and offer timely psychological support. No experimental treatments are involved; the study only observes and analyzes existing clinical information.
