    Delayed Intracranial Complications After Concussion2006In: Journal of Trauma, ISSN 0022-5282, E-ISSN 1529-8809, Vol. 61, no 3, p. 577-581Article in journal (Refereed)
    Abstract [en]

    Background and Methods: The incidence of readmissions because of delayed intracranial complications within 3 weeks after observation for the sole diagnosis of concussion was examined in a national cohort. A nested case-control design was used to analyze the association between clinical factors as well as early computed tomography (CT) scan examination and these complications.

    Results: Out of 100,784 patients hospitalized because of concussion during ten years, 127 (0.13%) patients were readmitted because of a delayed intracranial complication. High clinical severity grade (odds ratio [OR] 2.0, confidence interval [CI] 1.2-3.6), minor CT scan abnormalities (OR 1.7, CI 0.8-3.4) and male gender (OR 2.2, CI 1.4-3.5) were associated with an increased risk of delayed, intracranial complications.

    Conclusion: The incidence of delayed intracranial complications after primarily uncomplicated concussion was low. High clinical severity grade and male gender were risk factors. We failed to demonstrate an additional value of the acute CT scan examination to predict these complications.

    Erythropoiesis in multiply injured patients2006In: Journal of Trauma, ISSN 0022-5282, E-ISSN 1529-8809, Vol. 61, no 5, p. 1285-1291Article, review/survey (Refereed)
    Abstract [en]

    Posttraumatic anemia in multiply injured patients is caused by hemorrhage, reduced red blood cell survival, and impaired erythropoiesis. Trauma-induced hyperinflammation causes impaired bone-marrow function by means of blunted erythropoietin (EPO) response, reduced iron availability, suppression and egress of erythroid progenitor cells. To treat posttraumatic anemia in severely injured patients, symptomatic therapy by blood transfusion is not sufficient. Furthermore, EPO, iron, and the use of red cell substitutes should be considered. The posttraumatic systemic inflammatory response syndrome (SIRS) induces posttraumatic anemia. Thus, a worsening of SIRS by a "second-hit" through blood transfusion ought to be avoided.

    A prospective longitudinal study of posttraumatic stress disorder symptom trajectories after burn injury2011In: Journal of Trauma, ISSN 0022-5282, E-ISSN 1529-8809, Vol. 71, no 6, p. 1808-1815Article in journal (Refereed)
    Abstract [en]

    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.

    A simplified domain structure of the Burn-Specific Health Scale-Brief (BSHS-B): A tool to improve its value in routine clinical work2008In: Journal of Trauma, ISSN 0022-5282, E-ISSN 1529-8809, Vol. 64, no 6, p. 1581-1586Article in journal (Refereed)
    Abstract [en]

    Background:

    Injury-specific instruments with good psychometric properties are valuable in the assessment of health status after trauma. Previous studies of burn-specific health have attempted to create broad domains such as physical and psychological health, but these domains have not been validated. In this study, burn-specific health domains were explored and validated by a factor analytic approach.

    Methods:

    Participants were 334 former burn patients injured between 1980 and 2000. Data were collected from medical charts and by a postal questionnaire, the Burn Specific Health Scale-Brief (BSHS-B). The nine subscales of the BSHS-B were subjected to second-order factor analysis. The sample was split into two subsamples that were equal with respect to burn severity.

    Results:

    The factor structure was well replicated in each of the subsamples and in the total sample. Three internally consistent and well separated domains were derived: affect and relations (BSHS-B subscales interpersonal relationships, affect, sexuality), function (simple abilities, hand function), and skin involvement (heat sensitivity, treatment regimens, body image). The work subscale of the BSHS-B was excluded from the analysis because of consistent double loadings. The three domains had intelligible associations with injury-specific and sociodemographic variables.

    Conclusion:

    The underlying structure of the BSHS-B comprises three clinically meaningful health domains. The work subscale is not part of these domains and can be considered a separate outcome domain. The domain scores increase the understanding of outcome after burn injury and could prove useful in clinical use of the BSHS-B.

    Burn Specific Health up to 24 Months After the Burn: A Prospective Validation of the Simplified Model of the Burn Specific Health Scale-Brief2011In: Journal of Trauma, ISSN 0022-5282, E-ISSN 1529-8809, Vol. 71, no 1, p. 78-84Article in journal (Refereed)
    Abstract [en]

    Background: Outcome after burn injury is a multidimensional concept, but few multidimensional, injury-specific outcome measures have been psychometrically evaluated. A recent cross-sectional study using the Burn Specific Health Scale-Brief (BSHS-B) found three psychometrically sound health domains: function, skin involvement, and affect and relations. The aim of this study was to reexamine the psychometric properties of the BSHS-B using a prospective study design. Methods: Ninety-four consecutive adult patients with burns were included and asked to fill in questionnaires, the BSHS-B, the Hospital Anxiety and Depression Scale, and the short-form 36 (SF-36), at 6 months, 12 months, and 24 months postburn. Results: The factor structure was replicated and the three domains, function, skin involvement, and affect and relations, had excellent internal consistency. Over time the scores of function and skin involvement increased, indicating health improvement, whereas the domain affect and relations did not change over time. At 6 months and 12 months postburn, all domains were associated with burn severity. The function domain was highly associated with the SF-36 subscales physical functioning and role-physical, the affect and relations domain was highly associated with the Hospital Anxiety and Depression Scale and the SF-36 subscales denoting psychological health, and the domain skin involvement was highly associated with subscales indicating role-concerns, social functioning, vitality, and mental health. Conclusion: The psychometric properties of the BSHS-B domains were excellent and they had intelligible concurrent associations with other measures. Thus, the simplified model of the BSHS-B is a reliable, valid, and useful tool in describing postburn health over time.

    Health-related quality of life 2 years to 7 years after a severe burn2011In: Journal of Trauma, ISSN 0022-5282, E-ISSN 1529-8809, Vol. 71, no 5, p. 1435-1441Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:

    Knowledge concerning the trajectory andpredictors of health-related quality of life (HRQoL) years after burninjury is fragmentary and these factors were therefore assessed usingthe EQ-5D questionnaire.

    METHODS:

    Consecutive adult burnpatients were included during hospitalization and assessed at 3 months, 6months, and 12 months. In addition, an interview was performed at 2years to 7 years postburn. Data concerning injury characteristics,sociodemographic variables, psychiatric disorders, and HRQoL wereobtained.

    RESULTS:

    The EQ-5D dimension Mobility improvedbetween hospitalization and 3 months, while Anxiety/Depression improvedbetween 12 months and 2 years to 7 years. Other dimensions improvedgradually. At 2 years to 7 years, only the dimensions Pain/Discomfortand Usual activities were lower than in the general population. Inaddition, overall HRQoL was lower than in the general population whenmeasured by EQ VAS but not by EQ-5D index. EQ-5D index at 2 years to 7years was predicted by EQ-5D index at 12 months and concurrent workstatus and pain. EQ VAS at 2 years to 7 years was predicted by previousassessments of work status, posttraumatic stress disorder and EQ VAS,and concurrent work status and substance abuse. Total amount ofexplained variance ranged between 17% and 57%.

    CONCLUSIONS:

    HRQoLafter burn is conveniently screened by EQ VAS. Impairment after 2 yearsto 7 years is mainly reflected in the EQ dimensions Pain/Discomfort andUsual activities and can be predicted in part by information availablebefore or at 12 months.
