Article: Disability after injury: the cumulative burden of physical and mental health.

ABSTRACT: Injury is one of the leading contributors to the global burden of disease. The factors that drive long-term disability after injury are poorly understood. The main aim of the study was to model the direct and indirect pathways to long-term disability after injury. Specifically, the relationships between 3 groups of variables and long-term disability were examined over time. These included physical factors (including injury characteristics and premorbid disability), pain severity (including pain at 1 week and 12 months), and psychiatric symptoms (including psychiatric history and posttraumatic stress, depression, and anxiety symptoms at 1 week and 12 months). A multisite, longitudinal cohort study of 715 randomly selected injury patients (from April 2004 to February 2006). Participants were assessed just prior to discharge (mean = 7.0 days, SD = 7.8 days) and reassessed at 12 months postinjury. Injury patients who experienced moderate/severe traumatic brain injury and spinal cord injury were excluded from the study. The World Health Organization Disability Assessment Schedule 2.0 was used to assess disability at 12 months after injury. Disability at 12 months was up to 4 times greater than community norms, across all age groups. The development and maintenance of long-term disability occurred through a complex interaction of physical factors, pain severity across time, and psychiatric symptoms across time. While both physical factors and pain severity contributed significantly to 12-month disability (pain at 1 week: total effect [TE] = 0.2, standard error [SE] < 0.1; pain at 12 months: TE = 0.3, SE < 0.1; injury characteristics: TE = 0.3, SE < 0.1), the total effects of psychiatric symptoms were substantial (psychiatric symptoms 1 week: TE = 0.30, SE < 0.1; psychiatric symptoms 12 months: TE = 0.71, SE < 0.1). Taken together, psychiatric symptoms accounted for the largest proportion of the variance in disability at 12 months. While the physical and pain consequences of injury contribute significantly to enduring disability after injury, psychiatric symptoms play a greater role. Early interventions targeting psychiatric symptoms may play an important role in improving functional outcomes after injury.The Journal of Clinical Psychiatry 02/2013; 74(2):e137-43. · 5.80 Impact Factor -

ABSTRACT: To examine the relationship between psychological response to injury at 1 week and 3 months, and disability at 12 months. Multisite, longitudinal study. 802 adult patients admitted to trauma services at four Australian hospitals from 13 March 2004 to 21 February 2006 were assessed before discharge and followed up at 3 and 12 months. Disability, measured with the 12-item version of the World Health Organization Disability Assessment Schedule II. Logistic regression identified the degree to which high levels of depression and post-traumatic stress disorder (PTSD) at 1 week and at 3 months predicted disability at 12 months. After controlling for demographic variables and characteristics of the injury, patients with PTSD or subsyndromal PTSD at 1 week were 2.4 times more likely, and those with depression at 1 week were 1.9 times more likely to have high disability levels at 12 months. PTSD at 3 months was associated with 3.7 times, and depression at 3 months with 3.4 times the risk of high disability at 12 months. PTSD and depression at 1 week and at 3 months after injury significantly increased the risk of disability at 12 months. Routine assessment of symptoms of depression and PTSD in patients who have been physically injured may facilitate triage to evidence-based treatments, leading to improvement in both physical and psychological outcomes.The Medical journal of Australia 05/2009; 190(7 Suppl):S71-4. · 2.81 Impact Factor
