The appropriate use of thromboprophylaxis in medical patients admitted to hospital can substantially reduce the overall burden of disease due to venous thromboembolism. However, the use of thromboprophylaxis in medical setting appears to be generally poor leaving at-risk patients unprotected.
We aim to analyse the incidence of symptomatic thromboembolic disease following hospitalisation in medical setting and the efficacy of a multicomponent prevention approach in emergency department including systematic evaluation of thrombosis risk factors and remembers of thrombophylaxis indications and modalities for acutely ill medical patients.
Design: cluster randomized interventional study - Observational study at patient level
Setting: 30 French emergency departments
Patients: Patients over 40 years old admitted in participating emergency departments and hospitalized for acute medical reasons.
Main judgment criteria: the rate of symptomatic thromboembolic events and severe haemorrhage during a formal 3-months follow-up after hospital admission in patients hospitalized at least 48 hours.

- Symptomatic venous thromboembolic events and severe haemorrhage [ Time Frame: 3 months ]
the rate of symptomatic venous thromboembolic events and severe haemorrhage during a formal 3-months follow-up after hospital admission in patients hospitalized at least 48 hours.
All possible thromboembolic events, severe haemorrhages and deaths will be analysed by an adjudication committee blinded of group assignation. Sudden death without obvious cause according to the adjudication committee will be considered as possible fatal pulmonary embolism.
- Rate of symptomatic venous thromboembolic events [ Time Frame: 3 months ]- The rate of symptomatic venous thromboembolic events during a formal 3-months follow-up after hospital admission oin all included patients oin patients hospitalized at least 48 hours. oin patients hospitalized less than 48 hours
- Rate of thromboembolic events [ Time Frame: 3 months ]- The rate of thromboembolic events oin patients who had an appropriate thromboprophylactic treatment oin patients who had an inappropriate thromboprophylactic treatment oin patients who had no thromboprophylactic treatment
- rate of severe haemorrhage [ Time Frame: 3 months ]- The rate of severe haemorrhage oin patients who had an appropriate thromboprophylactic treatment oin patients who had an inappropriate thromboprophylactic treatment oin patients who had no thromboprophylactic treatment
- appropriateness of thromboprophylaxis [ Time Frame: 3 months ]
- The appropriateness of thromboprophylaxis in the overall population and according to group assignation:
oNumber of patients needing prevention treatment according to international recommendations and who have an appropriate treatment.
oNumber of patients without indication of thromboprophylaxis and who do not receive a treatment
