There are currently no international guidelines regarding treatment in the early rehabilitation phase for persons with severe traumatic brain injury (TBI), and only a few studies have investigated the effect of integrating rehabilitation into acute TBI care. The aim of the study was to evaluate whether a continuous chain of rehabilitation that begins with the acute phase could improve the functional outcome of severe TBI patients, compared to a broken chain of rehabilitation that starts in the sub-acute phase of TBI. A total of 61 surviving patients with severe TBI were included in a quasi-experimental study conducted at the Level I trauma center in Eastern Norway. In the study, 31 patients were in the early rehabilitation group (Group A) and 30 patients were in the delayed rehabilitation group (Group B). The functional outcomes were assessed 12 months post-injury with the Glasgow Outcome Scale Extended (GOSE) and the Disability Rating Scale (DRS). A favorable outcome (GOSE 6-8) occurred in 71 % of the patients from Group A versus 37 % in Group B ( p = 0.007). The DRS score was significantly better in Group A ( p = 0.03). The ordinal logistic regression analysis was used to quantify the relationship between the type of rehabilitation chain and the GOSE. A better GOSE outcome was found in patients from Group A (unadjusted OR 3.25 and adjusted OR 2.78, respectively). These results support the hypothesis that better functional outcome occurs in patients who receive early onset and a continuous chain of rehabilitation.
PCS symptoms were reported to a greater degree in persons with mild TBI at 3 months post-injury. One year after injury, no differences were found between TBI groups on the presence of PCS.
Background: The aim of this prospective, population-based study is to present the incidence of hospital-treated traumatic brain injury (TBI) in Oslo, Norway, and to describe the severity of brain injuries and outcome of the patients’ acute medical care. Methods: Data were obtained from hospital admission registers and medical records from May 2005 to May 2006. The initial severity of TBI was measured by the Glasgow Coma Scale. The region is urban with a population of 534,129. Results: The 445 patients identified represent an annual incidence of 83.3/100,000. The median age was 29 years. The male:female ratio was 1.8:1.0. The highest incidence of TBI hospitalizations was found in the elderly males and the youngest children. The most common causes of TBI were falls (51%) and transport accidents (29.7%). Intracranial lesions were found more often in the elderly. The case fatality rate was 2.0/100 hospitalized patients and was highest in the elderly. Conclusions: The incidence of hospital-treated TBI in this study is considerably lower than that found in previous studies from Norway and Scandinavia. Despite the apparent decline in TBI hospitalization rates, our findings should also draw attention to the need for more effective preventive programmes related to falls. Studies that assess long-term consequences of TBI in elderly patients are also needed.
Aims: The aims of this study were to assess the incidence of hospital-admitted severe traumatic brain injury (TBI) in the adult population in Norway, and to determine whether there were differences in the epidemiological characteristics of severe TBI between rural and urban regions. Methods: A prospective population-based study on adults with severe TBI admitted to the Norwegian Trauma Referral Centres during the 2-year period (2009–2010). The electronic patient register was searched weekly for ICD-10 diagnoses of intracranial injuries (S06.0–S06.9) to identify patients. Severe TBI was defined as lowest unsedated Glasgow Coma Scale Score ≤8 during the first 24 h after injury. Results: The annual age-adjusted incidence was estimated at 5.2/100,000 in 2009 and 4.1/100,000 in 2010. The highest frequency of hospitalized patients was found among the youngest and the oldest age groups. The most common causes of injury were falls and transport accidents. The highest in-hospital case-fatality rate was found among the oldest patients. There were consistent epidemiological characteristics of severe TBI from both rural and urban regions. Conclusions: The incidence of hospital-admitted patients with severe TBI in this national study supports the declining incidence of TBI reported internationally. No major differences were found in epidemiological characteristics between the urban and rural parts of Norway.
Outcome studies on traumatic brain injury (TBI) have shown that functional status can be predicted by demographic, injury severity, and trauma-related factors. Concurrent cognitive functions as one of the determinants of functional outcome is less documented. This study evaluated the effects of concurrent neuropsychological measures on functional outcome 1 year after injury. Neuropsychological data, employment status, self-reported fatigue, and the Glasgow Outcome Scale-Extended (GOSE) were collected from 115 persons with TBI (ranging from mild to severe) at 3 and 12 months postinjury. Principal components analysis was conducted with the neuropsychological measures and three components emerged. Multiple regression analysis, controlling for demographic and injury severity related factors, was used to test the effects of cognitive components at 12 months on functional outcome (GOSE). One year after injury, 64% were categorized as "good recovery" and 36% as "moderate disability" according to GOSE. Good functional recovery depended on shorter duration of posttraumatic amnesia, less fatigue, absence of intracranial pathology, higher education, and better performance on cognitive measures. The predictive values of Verbal/Reasoning and Visual/Perception components are supported; each added significantly and improved prediction of functional outcome. The Memory/Speed component showed a near-significant relationship to outcome.
