The purpose of this study was to characterize current dosing practices and timing of initiation of pharmacological VTE chemoprophylaxis at trauma centers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was an international, cross-sectional survey of trauma providers. The survey was sponsored by the American Association for the Surgery of Trauma (AAST) and distributed to AAST members. The survey included 38 questions about practitioner demographics, experience, level and location of trauma center, and individual\/site-specific practices regarding the dosing, selection, and timing of initiation of pharmacological VTE chemoprophylaxis in trauma patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred eighteen trauma providers responded (estimated response rate 6.9%). Most respondents were at level 1 trauma centers (100\/118; 84.7%) and had &gt;10 years of experience (73\/118; 61.9%). While multiple dosing regimens were used, the most common dose reported was enoxaparin 30\u2009mg every 12 hours (80\/118; 67.8%). The majority of respondents (88\/118; 74.6%) indicated adjusting the dose in patients with obesity. Seventy-eight (66.1%) routinely use antifactor Xa levels to guide dosing. Respondents at academic institutions were more likely to use guideline-directed dosing (based on the Eastern Association of the Surgery of Trauma and the Western Trauma Association guidelines) of VTE chemoprophylaxis compared with those at non-academic centers (86.2% vs 62.5%; p=0.0158) and guideline-directed dosing was reported more often if the trauma team included a clinical pharmacist (88.2% vs 69.0%; p=0.0142). Wide variability in initial timing of VTE chemoprophylaxis after traumatic brain injury, solid organ injury, and spinal cord injuries was found.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A high degree of variability exists in prescribing and monitoring practices for the prevention of VTE in trauma patients. Clinical pharmacists may be helpful on trauma teams to optimize dosing and increase prescribing of guideline-concordant VTE chemoprophylaxis.<\/jats:p><\/jats:sec>","DOI":"10.1136\/tsaco-2022-001070","type":"journal-article","created":{"date-parts":[[2023,5,12]],"date-time":"2023-05-12T13:56:07Z","timestamp":1683899767000},"page":"e001070","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":23,"title":["Survey
