The aim of this study was to describe the timing of venous thromboembolism diagnosis in patients with severe burns and determine the relationship between venous thromboembolism prophylaxis and venous thromboembolism development in a large trauma hospital. A retrospective cohort study over 10 years from 2009 to 2019 was conducted. Records of 226 patients with >20% total body surface area burns were surveyed, and 20 patients with symptoms suggestive of venous thromboembolism had a diagnosis of VTE confirmed on imaging. Enoxaparin was the most common primary thromboprophylaxis (85%, n = 192), followed by heparin (13.71%, n = 31) and sequential compression devices (0.88%, n = 2). Compared with patients who did not develop a venous thromboembolism, patients who developed a venous thromboembolism had a mean difference in time from admission to thromboprophylaxis prescription of 1.72 days (95% CI = −1.50 to 4.92, p > 0.05) and 10.51 days in those who developed a pulmonary embolus (mean difference = 10.51, 95% CI = 3.73 to 17.32, p = 0.0006). A threshold of 4 days was identified by which 96% of patients who never developed venous thromboembolism during admission were prescribed prophylaxis, compared with 32% of those who developed a pulmonary embolus. No bleeding or adverse events were recorded. Timely prescription of thromboprophylaxis in patients with severe burns is critical in reducing venous thromboembolism incidence. Avoidance of delay post injury is especially critical in preventing venous thromboembolism development. Guidelines on thromboprophylaxis must be considered on an individualised patient basis, considering likely surgical requirements and obesity.
