title: [Evaluation of venous thromboembolism risk and prophylaxis among hospitalized patients in Brazzaville].
abstract: OBJECTIVE
  To identify patients at risk of venous thromboembolism and to evaluate the use of preventive measures.
  
  
  METHODS
  A cross-sectional given-day observational and descriptive study was conducted among patients in the Brazzaville University Hospital. All hospitalized adult patients were included. Compliance with the recommendations of the American College of Chest Physicians (2004 version) on the risk of venous thromboembolism and use of prevention was evaluated. The study included 292 patients hospitalized from July 1 to 4, 2014 in eight medicine and four surgery and gynecology-obstetrics wards.
  
  
  RESULTS
  The study population included 214 (73.3 %) patients at risk of venous thromboembolism hospitalized in medicine (n=83, 38.7 %), surgery (n=82, 38.3 %), and gynecology-obstetrics (n=49, 23 %) wards. There were 92 men (43 %) and 122 women (57 %), mean age 45.9±17.7years (range: 18-88). The risk of venous thromboembolism was low in 15 patients (7 %), moderate in 104 patients (48.6 %), and high in 95 patients (44.4 %). The main risk factors identified were: for surgical patients, long immobilization (42.6 %) and age>40years (33.1 %); for medical patients, long immobilization (24.7 %) and age>60years (18.5 %); for gynecology-obstetrics patients, age<60years (44 %), multiparity (15.4 %) and long immobilization (10.7 %). One hundred sixty-nine patients (79 %) had received one measure of prevention. There were 45 (54.2 %) medical patients, 81 (99 %) surgical patients and 43 (88 %) gynecology-obstetrics patients. Pharmacological prevention was used in 97 patients (57.4 %), mechanical prevention in 33 patients (19.5 %), and the two types of prevention in 39 patients (23.1 %).
  
  
  CONCLUSIONS
  The risk of venous thromboembolism is common in hospitalized patients in Brazzaville, and the need for prevention is perceived but poorly understood. It is therefore essential to improve our knowledge of venous thromboembolism and its prevention.
