To date, there have been no prospective comparisons of prescribed thromboprophylaxis agents and limited external validation of different risk assessment methods (RAMs). We sought to evaluate UK practice via a survey.A cross-sectional electronic survey composed of 10 questions (online supplemental material) was developed by a diverse co-applicant team preparing a National Institute for Health and Care Research application,5 including topic experts from orthopaedic and vascular surgery, emergency medicine (EM), thrombosis and haemostasis, and patient representatives. The survey was conducted using Smart Survey® between 1 February and 25 March 2022, disseminated by email through the Trainee Emergency Research Network6 and WhatsApp® via the Royal College of Emergency Medicine clinical leads network.
