Risk Factors for Posttraumatic Stress Disorder in Acute Trauma Patients.
JOURNAL OF ORTHOPAEDIC TRAUMA(2021)
Abstract
OBJECTIVE:To identify risk factors for posttraumatic stress disorder (PTSD) after traumatic injury.
SETTING:Single urban Level I trauma center.
DESIGN:Prospective.
PATIENTS/PARTICIPANTS:Three hundred men (66%) and 152 women treated for traumatic injuries were administered the PTSD checklist for a Diagnostic and Statistical Manual of Mental Disorders fifth edition (PCL-5) survey during their first post-hospital visit over a 15-month period.
INTERVENTION:Screening for PTSD in trauma patients.
MAIN OUTCOME MEASUREMENT:The prevalence of disease and risk factors for the development of PTSD based on demographic, medical, injury, and treatment variables.
RESULTS:One hundred three patients screened positive for PTSD (26%) after a mean of 86 days after injury. Age less than 45 years was an independent risk factor for the development of PTSD [odds ratio (OR) 2.64, 95% confidence interval (CI) (1.40-4.99)]. Mechanisms of injury associated with the development of PTSD included pedestrians struck by motor vehicles [OR 7.35, 95% CI (1.58-34.19)], motorcycle/all terrain vehicle crash [OR 3.17, 95% CI (1.04-9.65)], and victims of crime [OR 3.49, 95% CI (0.99-9.20)]. Patients sustaining high-energy mechanism injuries and those who were victims of crime scored higher on the PCL-5 [OR 2.39, 95% CI (1.35-4.22); OR 4.50, 95% CI (2.52-8.05), respectively].
CONCLUSIONS:One quarter of trauma patients screened positive for PTSD at 3 months after their injury. A mechanism of injury is a risk factor for PTSD, and younger adults, victims of crime, and pedestrians struck by motor vehicles are at higher risk. These findings offer the potential to more effectively target and refer vulnerable patient populations to appropriate treatment.
