Traumatic brain injury (TBI) patients are known to be at high risk for venous thromboembolic events (VTEs). The Brain Trauma Foundation Guidelines (2007) state that low-molecular-weight heparin or unfractionated heparin should be used to prevent VTE complications, but suggest that there is an increased risk of expansion of intracranial hemorrhages (ICH)(More)
Nowadays, in all countries, public resources for healthcare are inadequate to meet the demands for the services. Therefore, policy makers should provide the most effective healthcare services to citizens within the limited available resources. During the past decades, lots of research using operations research techniques, tools, and theories has been(More)
BACKGROUND Intracranial hypertension can cause secondary damage after a traumatic brain injury. Aggressive medical management might not be sufficient to alleviate the increasing intracranial pressure (ICP), and decompressive craniectomy (DC) can be considered. Decompressive craniectomy can be divided into categories, according to the timing and rationale(More)
OBJECTIVE To evaluate the effect of a specialized multidisciplinary tracheostomy team on outcome of patients with severe traumatic brain injury (sTBI). DESIGN Retrospective study with historical controls. PARTICIPANTS Twenty-seven patients with sTBI tracheostomized before implementation of the tracheostomy team approach and 34 patients followed by the(More)
OBJECT The Brain Trauma Foundation has published guidelines on the surgical management of traumatic subdural hematoma (SDH). However, no data exist on the proportion of patients with SDH that can be selected for conservative management and what is the outcome of these patients. The goals of this study were as follows: 1) to establish what proportion of(More)
PRIMARY OBJECTIVE To investigate the relationship between pre-injury alcohol abuse and intoxication at time of injury on duration of post-traumatic amnesia (PTA) as well as on early functional and neurobehavioural outcomes in persons with traumatic brain injury (TBI) hospitalized in an acute care setting. METHODS AND PROCEDURE Sixty persons with mild,(More)
