Severity of injury does not have any impact on posttraumatic stress symptoms in severely injured patients
Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine volume 17, Article number: O1 (2009)
Due to improved surgical techniques and more efficient decision making in treating severely injured patients, survival rates among severely injured patients have increased over the years. There are discrepancies in the literature whether the severity of injury is a risk factor for development of posttraumatic stress symptoms or not. This study was initiated to evaluate the incidence and identify risk factors for developing posttraumatic stress symptoms, using both extensive trauma related data and data assessing the psychological trauma, in a population of severely injured patients.
101 patients admitted to the Department of Multitrauma and Spinal Cord Injury at Sunnaas Rehabilitation Hospital from 2003 to 2005, prospectively completed a semistructured psychological interview and questionnaires, such as Impact of Event Scale-Revised. In addition, extensive injury-related data, such as Injury Severity Score (ISS), New Injury Severity Score (NISS), and Probability of Survival (PS) were collected.
One third (31%) had multiple traumas, and the rest (69%) had spinal cord injuries. Mean NISS was 31.5 (SD 13.7). Only 5% met diagnostic criteria for Posttraumatic Stress Disorder (PTSD) and 8% met the criteria for Subsyndromal PTSD. Injury-related data did not influence the prevalence of posttraumatic stress symptoms, however, some psychosocial variables did have a significant impact.
We found a low incidence of PTSD and Subsyndromal PTSD. No significant differences were found between the patients suffering from posttraumatic stress symptoms and the non-symptoms group in relation to injury-related data such as ISS/NISS, PS, or multiple trauma versus spinal cord injury, meaning that the severity of injury does not have any impact on posttraumatic stress symptoms in severely injured patients. The most evident risk factors for developing posttraumatic stress symptoms were symptoms of anxiety, female gender and negative attitudes toward emotional expression.
