Research Article: Factors that influence the administration of tranexamic acid (TXA) to trauma patients in prehospital settings: a systematic review
Abstract:
Objective In the UK there are around 5400 deaths annually from injury. Tranexamic acid (TXA) prevents bleeding and has been shown to reduce trauma mortality. However, only 5% of UK major trauma patients who are at risk of haemorrhage receive prehospital TXA. This review aims to examine the evidence regarding factors influencing the prehospital administration of TXA to trauma patients. Design Systematic literature review. Data sources AMED, CENTRAL, CINAHL, Cochrane Database of Systematic Reviews, Conference Proceedings Citation Index—Science, Embase and MEDLINE were searched from January 2010 to 2020; searches were updated in June 2022. Clinicaltrials.gov and OpenGrey were also searched and forward and backwards citation chasing performed. Eligibility criteria All primary research reporting factors influencing TXA administration to trauma patients in the prehospital setting was included. Data extraction and synthesis Two independent reviewers performed the selection process, quality assessment and data extraction. Data were tabulated, grouped by setting and influencing factor and synthesised narratively. Results Twenty papers (278?249 participants in total) were included in the final synthesis; 13 papers from civilian and 7 from military settings. Thirteen studies were rated as ‘moderate’ using the Effective Public Health Practice Project Quality Assessment Tool. Several common factors were identified: knowledge and skills; consequences and social influences; injury type (severity, injury site and mechanism); protocols; resources; priorities; patient age; patient sex. Conclusions This review highlights an absence of high-quality research. Preliminary evidence suggests a host of system and individual-level factors that may be important in determining whether TXA is administered to trauma patients in the prehospital setting. Funding and registration This review was supported by Research Capability Funding from the South Western Ambulance Service NHS Foundation Trust and the National Institute for Health Research Applied Research Collaboration South West Peninsula.

Introduction:
At least 20?000 individuals are severely injured in England each year, resulting in approximately 5400 deaths, of which 2400 occur before hospital arrival. 1 The CRASH2 trial provided strong evidence of the effectiveness of tranexamic acid (TXA) in reducing mortality in bleeding trauma patients, 2 with CRASH3 then extending its use to isolated head injuries. 3 When given within 3?hours of injury, TXA reduces death from bleeding in all types of trauma. 4 An additional exploratory analysis concluded that the…
