A concerted effort to tackle the global health problem posed by traumatic brain injury (TBI) is long overdue. TBI is a public health challenge of vast, but insufficiently recognised, proportions. Worldwide, more than 50 million people have a TBI each year, and it is estimated that about half the world's population will have one or more TBIs over their lifetime. TBI is the leading cause of mortality in young adults and a major cause of death and disability across all ages in all countries, with a disproportionate burden of disability and death occurring in low-income and middle-income countries (LMICs). It has been estimated that TBI costs the global economy approximately $US400 billion annually. Deficiencies in prevention, care, and research urgently need to be addressed to reduce the huge burden and societal costs of TBI. This Commission highlights priorities and provides expert recommendations for all stakeholders—policy makers, funders, health-care professionals, researchers, and patient representatives—on clinical and research strategies to reduce this growing public health problem and improve the lives of people with TBI.Additional co-authors: Endre Czeiter, Marek Czosnyka, Ramon Diaz-Arrastia, Jens P Dreier, Ann-Christine Duhaime, Ari Ercole, Thomas A van Essen, Valery L Feigin, Guoyi Gao, Joseph Giacino, Laura E Gonzalez-Lara, Russell L Gruen, Deepak Gupta, Jed A Hartings, Sean Hill, Ji-yao Jiang, Naomi Ketharanathan, Erwin J O Kompanje, Linda Lanyon, Steven Laureys, Fiona Lecky, Harvey Levin, Hester F Lingsma, Marc Maegele, Marek Majdan, Geoffrey Manley, Jill Marsteller, Luciana Mascia, Charles McFadyen, Stefania Mondello, Virginia Newcombe, Aarno Palotie, Paul M Parizel, Wilco Peul, James Piercy, Suzanne Polinder, Louis Puybasset, Todd E Rasmussen, Rolf Rossaint, Peter Smielewski, Jeannette Söderberg, Simon J Stanworth, Murray B Stein, Nicole von Steinbüchel, William Stewart, Ewout W Steyerberg, Nino Stocchetti, Anneliese Synnot, Braden Te Ao, Olli Tenovuo, Alice Theadom, Dick Tibboel, Walter Videtta, Kevin K W Wang, W Huw Williams, Kristine Yaffe for the InTBIR Participants and Investigator
In November 2017, the Lancet Neurology Commission on Traumatic Brain Injury (TBI) highlighted existing deficiencies in epidemiology, patient characterization, identifying best practice, outcome assessment, and evidence generation. The Commission concluded that C needed to address deficiencies in prevention , and made a recommendation for large collaborative studies which could provide the framework for precision medicine and comparative effectiveness research (CER).
Decompressive hemicraniectomy is commonly performed in patients with traumatic brain injury (TBI) with diffuse brain swelling or refractory raised intracranial pressure. Expansion of hemorrhagic contusions in TBI patients is common, but its frequency following decompressive hemicraniectomy has not been well established. The aim of this retrospective study was to determine the rate of hemorrhagic contusion expansion following unilateral hemicraniectomy in severe TBI, to identify factors associated with contusion expansion, and to examine whether contusion expansion is associated with worsened clinical outcomes. Computed tomography (CT) scans of 40 consecutive patients with non-penetrating TBI who underwent decompressive hemicraniectomy were analyzed. Hemorrhagic contusion volumes were measured on initial, last pre-operative, and first post-operative CT scans. Mortality and 6-month Glasgow Outcome Scale (GOS) score were recorded. Hemorrhagic contusions of any size were present on the initial head CT scan in 48% of patients, but hemorrhagic contusions with a total volume of >5 cc were present in only 10%. New or expanded hemorrhagic contusions of >or=5 cc were observed after hemicraniectomy in 58% of patients. The mean volume of increased hemorrhage among these patients was 37.1+/-36.3 cc. The Rotterdam CT score on the initial head CT was strongly associated with the occurrence and the total volume of expanded hemorrhagic contusions following decompressive hemicraniectomy. Expanded hemorrhagic contusion volume greater than 20 cc after hemicraniectomy was strongly associated with mortality and poor 6-month GOS even after controlling for age and initial Glasgow Coma Scale (GCS) score. Expansion of hemorrhagic contusions is common after decompressive hemicraniectomy following severe TBI. The volume of hemorrhagic contusion expansion following hemicraniectomy is strongly associated with mortality and poor outcome. Severity of initial CT findings may predict the risk of contusion expansion following hemicraniectomy, thereby identifying a subgroup of patients who might benefit from therapies aimed at augmenting the coagulation system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
