title: [Perception of the risk of venous thromboembolic disease in primary care].
abstract: OBJECTIVE
  To determine the prevalence in out-patients of risk factors leading to venous thromboembolic disease (VTE); and to analyse what perception primary care centre (PCC) doctors have of this risk and what attitude they adopt to therapy.
  
  
  METHODS
  1) An observational, crossover study, with patients included at random. 2) A study with a teaching intervention, which was neither controlled nor randomised.
  
  
  METHODS
  PCC patients over 25 seen either on demand, with appointments or at home.
  
  
  METHODS
  A clinical history was composed, using a closed questionnaire. A risk category and therapeutic attitude were then assigned. A guide on prevention and treatment of VTD was presented and discussed in clinical sessions.
  
  
  RESULTS
  11 PCC doctors polled 272 patients. 45 of these had moderate to high risk of VTD; and 4 had one of the criteria of the European Accord on VTD prevention for commencing prophylactic treatment. In two of these four, it was thought necessary to start prophylaxis.
  
  
  CONCLUSIONS
  The prevalence of patients with moderate to high risk of VTD is 17% in patients over 25 who seek medical attention at PCCs. Doctors detected 50% of moderate to high risk patients. If the criteria used for in-patients were followed, prophylaxis should have been started in 1.5% of patients.
