The survey consisted of 27 questions of which 14 were analyzed in this study. Twelve questions addressed general information and two the way in which thromboprophylaxis was performed in patients with or without heightened risk of venous thromboembolism by using LMWH, UFH or other methods. We defined consensus for binary (yes\/no) questions at &gt;\u200980% or &lt;\u200920%; intermediate consensus between 60 and 80% or 20\u201340%; an agreement between 40 and 60% was designated controversial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 240 respondents between June 26, 2024 and July 10, 2024 were included.

The preferred method of thromboprophylaxis was controversial in patients without heightened risk of venous thromboembolism. In contrast, in patients with an increased risk of venous thromboembolism, an intermediate consensus of 75% was found for low molecular weight heparin only. However, pneumatic compression devices were the preferred method in high risk patients in North America.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The way in which thromboprophylaxis is carried out continues to be controversial.
