Information about the risk of venous thromboembolism and prophylactic practices around the world is limited. ENDORSE (Epidemiologic International Day for the Evaluation of Patients at Risk for Venous Thromboembolism in the Acute Hospital Care Setting) study is a multinational cross-sectional survey designed to assess the prevalence of venous thromboembolism (VTE) risk in the acute hospital care setting, and to determine the proportion of at-risk patients who receive appropriate prophylaxis. All hospital inpatients aged 40 years or above admitted to a medical ward, or those aged 18 years or above admitted to a surgical ward, in 358 randomly selected hospitals across 32 countries were assessed for risk of VTE on the basis of hospital chart review. The 2004 American College of Chest Physicians evidence-based consensus guidelines were used to assess venous thromboembolism risk and to determine whether patients were receiving recommended prophylaxis. Nine Hungarian centers were included in the international survey, and a total of 1300 patients were assessed for thrombosis risk in Hungary. Of these patients 39.9% (N=519) were judged at risk for VTE, including 58.2% (N=253) surgical and 30.8% (N=266) medical patients. 56.6% (N=294) of the total at-risk patients received ACCP-recommended VTE prophylaxis. Among major surgery patients 86.6% (N=219) received recommended prophylaxis compared with 28.2% (N=75) of medical patients. In Hungary more than two-thirds of at-risk hospitalized medical patients did not receive appropriate prophylaxis. ENDORSE results reinforced that a large proportion of hospitalized surgical and medical patients are at risk for VTE worldwide as well as in Hungary. The rate of at-risk patients receiving appropriate prophylaxis should be urgently increased.
