AI Predicts PTSD Risk From ER Visits

An artificial intelligence system named PREVIA is demonstrating a powerful new capability: forecasting a patient's risk of developing Post-Traumatic Stress Disorder (PTSD) after an emergency room visit. This AI chatbot analyzes a patient's description of the accident that brought them to the ER, detecting psychological signals associated with PTSD. In a recent study involving 145 emergency room patients in New York City, PREVIA successfully identified 100% of individuals who later developed PTSD. This performance surpassed that of a human doctor specializing in PTSD, who identified 89% of at-risk patients.

Researchers highlight that PREVIA's ability to predict PTSD from a patient's spontaneous response to the routine question, "What brought you to the ED?," is a significant breakthrough. The system scans for symptoms like amnesia or feeling disconnected from one's body, while also considering personal and medical history. This innovative approach can serve as an effective screener in busy emergency departments, potentially flagging individuals for crucial mental health support earlier than traditional methods. The open-source nature of PREVIA is expected to facilitate its widespread adoption by other hospitals.
