Abstract
Tranexamic acid (TXA) is an antifibrinolytic drug that is used in traumatic hemorrhage and traumatic brain injury. Although TXA is considered relatively safe and inexpensive and is widely available, data regarding its mechanisms, optimal dosing, and timing, as well as relative risks and benefits for different patient populations, are inconsistent. In this study, we aim to identify and summarize consensus research questions related to TXA across all National Trauma Research Action Plan (NTRAP) Delphi expert panels to identify priorities for future research on TXA in trauma. A secondary analysis was performed using consensus-based research priorities collected by 11 NTRAP topic panels using a Delphi methodology. The database of questions was queried for the keywords "tranexamic" and "TXA." The identified questions were sorted by subject matter and summarized. Seven panels included a total of 73 TXA-related questions. Forty-six questions reached consensus. The most addressed topic was outcomes (discussed in 64% of questions) followed by indications (49%) and specific patient populations (38%). Because of overlap across panels, questions were summarized and sorted by topic resulting in 21 priority research questions. Seventy-three total questions and 46 questions reaching consensus were identified by NTRAP panelists. The key topics identified in these questions should be prioritized in future funded research on TXA in trauma. Prognostic and Epidemiological; Level V.
