Abstract

BACKGROUND:: Psychologic problems are common after burns, and symptoms of posttraumatic stress disorder (PTSD) are some of the most prevalent. Risk factors for PTSD have been identified, but little is known about the onset and course of these symptoms. The objective was to investigate whether there are different PTSD symptom trajectories after burns. METHODS:: Ninety-five adults with burns were enrolled in a prospective study from in-hospital treatment until 12 months after burn. Symptoms of PTSD were assessed with the Impact of Event Scale-Revised and scores at 3, 6, and 12 months after the burn were used in a cluster analysis to detect trajectories. The trajectories were compared regarding known risk factors for PTSD using non-parametric analysis of variance. RESULTS:: Four clusters were identified: (1) resilient, with low levels of PTSD symptoms that decreased over time; (2) recovery, with high levels of symptoms that gradually decreased; (3) delayed, with moderate symptoms that increased over time; and (4) chronic, with high levels of symptoms over time. The trajectories differed regarding several risk factors for PTSD including life events, premorbid psychiatric morbidity, personality traits, avoidant coping, in-hospital psychologic symptoms, and social support. The resilient trajectory consistently had fewer of the risk factors and differed the most from the chronic trajectory. CONCLUSIONS:: There are subgroups among patients with burns that have different patterns of PTSD symptom development. These findings may have implications for clinical practice, such as the timing of assessment and the management of patients who present with these symptoms.
