Posttraumatic stress disorder symptoms after respiratory and cardiovascular emergencies predict risk of hospital readmission: A prospective cohort study

Twenty‐five percent of patients presenting to the emergency department (ED) for a respiratory or cardiovascular medical emergency develop clinically significant posttraumatic stress disorder (PTSD) symptoms. It is possible that development of PTSD symptoms in this cohort is associated with subsequent adverse physical health events. Our objective was to test whether clinically significant PTSD symptoms 30 days postdischarge are associated with increased risk for hospital readmission within 24 months after discharge among patients presenting to the ED for a respiratory or cardiovascular emergency.
