The ISTH is partnering with investigators from Monash University in Melbourne to help facilitate the PINOT Study, a survey of ISTH 2019 attendees about their thromboprophylaxis used in traveling to Australia.

There is a lack of consensus in international guidelines regarding appropriate thromboprophylaxis for prevention of air travel-related venous thromboembolism (VTE). During the XX ISTH Congress in Sydney in 2005, a questionnaire was sent to all delegates to assess the use of preventative measures for air travel-related VTE. The same questionnaire was sent to two other conferences. With over 2000 responses, it was demonstrated that nearly one third of delegates used some form of chemical prophylaxis such as aspirin, heparin or warfarin.

At the XXVII ISTH Congress in Melbourne 2019, we plan to collect information on types of thromboprophylaxis used by delegates, particularly since the introduction of the direct oral anticoagulants. Furthermore, a follow-up questionnaire will be emailed to all delegates eight weeks after the close of the ISTH Congress to assess rates of air travel-related VTE and any complications that may arise from thromboprophylaxis.

We are aiming to have over 3000 responses, and to establish if there is any benefit in using thromboprophylaxis to reduce risk of air travel-related venous thrombosis. Your assistance with this project is greatly appreciated!
