Psychological trauma in different mechanisms of traumatic injury: A hospital-based cross-sectional study

BACKGROUND

Psychological distress following traumatic injury can influence the patient health, well-being and quality of life; however, this impact may partly vary according to the type and severity of injury. We aimed to study the predominant distress causing cluster and individual symptoms of Post-Traumatic Stress Disorders (PTSD) at the clinical and subthreshold level in patients with traumatic injuries, based on the mechanism of injury (MOI).

METHODS

A hospital based cross-sectional study was conducted at a Level 1 Trauma Center utilizing PTSD Checklist to diagnose PTSD after one month of the traumatic event. All patients suffering from psychological distresses were assessed by a clinical psychologist in the trauma section. PTSD diagnostic criteria from DSM-5 were used to classify the patients. The inclusion criteria comprised of adult trauma patients who were directly involved in traumatic injuries and admitted under the Trauma Surgery services for a minimum of one day; have ability to provide written informed consent and can be assessed with the PCL-5 checklist after 4 weeks post-injury.

RESULTS

Two hundred patients completed PCL-5 checklist, of them 26 (13.0%) were positive for PTSD and 174 (87%) had subthreshold scores. The mean age of participants was 34.4±11.8 years and males constituted 90.5%. Road traffic injury (RTI) was most the frequent injury mechanism (59%). PTSD positive patients with RTI, fall of heavy objects, pedestrian injury and assaults had highest average scores on clusters of negative alterations in mood and cognitions (16.9, 18.0, 18.5, 17.0 respectively), followed by hyperarousal. Symptom of always being on the guard and having repeated unwanted or disturbing memories of the incident, was reported by nearly 100% PTSD positive patients. Patients with subthreshold scores also reported distressing symptoms on all four clusters of PTSD.

CONCLUSIONS

Patients with different MOI showed a broad range of psychological problems with respect to symptom clusters. Negative alteration in mood and cognition followed by hyperarousal caused higher level of distress in patients post traumatic injuries. Subthreshold symptoms of PTSD are more common and deserve more attention.

Trauma- and stressor-related disorders among hematological cancer patients with and without stem cell transplantation: protocol of an interview-based study according to updated diagnostic criteria

Background

Trauma- and stressor-related disorders pose an important threat for patients with medical conditions by negatively affecting the outcomes of the underlying somatic disease. Nevertheless, research on distress in the course of hematological cancer is sparse to date. For this patient group, however, treatment is often more toxic and invasive than for other cancer populations. A subgroup of these patients is treated with stem cell transplantation (SCT) which is associated with many stressors including spatial isolation or fear of life-threatening complications. Existing results are inconsistent and primarily based on self-report questionnaires and small samples. Moreover, diagnostic criteria of trauma- and stressor-related disorders have recently been updated.

Methods

This German cross-sectional study will recruit at total of 600 hematological cancer patients, of which 300 will have undergone either autologous or allogeneic SCT. Participants will be assessed for trauma- and stressor-related disorders (adjustment disorder and posttraumatic stress disorder) using a structured clinical interview (SCID-5) based on updated diagnostic criteria. Qualitative investigation of the reported stressors will be used for differential diagnostic investigations and to examine which stressors are experienced as most distressing. Additionally, severity of distress (i.e., general distress as well as anxious, depressive and stressor-related symptomatology) will be assessed by validated questionnaires. We will (i) provide the prevalence of trauma- and stressor-related disorders, (ii) investigate medical and sociodemographic risk factors and (iii) compare the levels of distress within the patient group (SCT vs. non-SCT) and between patients and age- and gender-matched reference groups from the German general population.

Discussion

This study will assess the prevalence of stressor-related disorders and the level of distress among hematological cancer patients across different treatment settings. Identification of medical and sociodemographic risk factors will help to closely monitor patients with a high risk of distress and to deliver psycho-oncological treatment as soon as possible. Comparisons between patients and norm values will be used to identify the need for psycho-oncological treatment in subgroups of hematological patients and thus help to further develop and implement tailored psycho-oncological interventions.

[Comorbid depressive and anxiety disorders in patients with cancer]

Patients with cancer face a high risk of comorbid depressive and anxiety disorders that have to be paradigmatically considered within a complex biopsychosocial context. Several conceptual challenges have to be mastered in arriving at a correct clinical diagnosis. Coexistent affective and anxiety disorders in cancer patients include a more dramatic subjective suffering, reduced psychological coping, possible negative interference with somatic treatment and rehabilitation, impaired quality of life and higher grades of psychosocial disability. They may also lead to an overall increased risk of somatic morbidity, a more rapid progression of cancer and a higher cancer-related mortality in the course of the disease. Manifold psychological, psychosocial and existential, cancer and treatment-related stressors have to be considered with respect to common neurobiological, especially neuroendocrine and neuroinflammatory mechanisms. Complex psychosomatic, somatopsychic and somato-somatic effects must always be considered. Evidence-based approaches in psychotherapy and pharmacotherapy exist for the integrative treatment of comorbid depressive and anxiety disorders in cancer.
