AbstractKnowledge of the breadth, nature, and volume of traumatic brain injury (TBI) and spinal cord injury (SCI) research can aid in research planning. This study aimed to provide an overview of existing TBI and SCI research to inform identification of knowledge translation (KT), systematic review (SR), and primary research opportunities. Topics and relevant articles from three large neurotrauma evidence resources were synthesized: the Global Evidence Mapping (GEM) Initiative (129 topics and 1644 articles), the Acquired Brain Injury Evidence-Based Review (ERABI; 152 topics and 732 articles), and the Spinal Cord Injury Rehabilitation Evidence (SCIRE) Project (297 topics and 1650 articles). A de-duplicated dataset of SRs, randomized controlled trials (RCTs), and other studies identified by these projects was created. In all, 145 topics were identified (66 TBI and 79 SCI), yielding 3466 research articles (1256 TBI and 2210 SCI). Topics with KT potential included cognitive therapies for TBI and prevention/management of urinary tract problems post-SCI, which accounted for 17% and 18%, respectively, of the TBI and SCI yield. Topics that may require SR included management of raised intracranial pressure in TBI, and ventilation and intermittent positive pressure interventions following SCI. Topics for which primary research may be needed included pharmacological therapies for neurological recovery post-TBI, and management of sleep-disordered breathing post-SCI. There was a larger volume of non-intervention (epidemiological) studies in SCI than in TBI. This comprehensive overview of TBI and SCI research can aid funding agencies, researchers, clinicians, and other stakeholders in prioritizing and planning TBI and SCI research.
