title: [Screening of patients at risk for hepatitis C virus infection in general medicine].
abstract: OBJECTIVE
  The French consensus conference recommended targeted screening for hepatitis C virus infection in patients with a past history of intravenous drug use or transfusion of blood products before 1991. The aim of this study was to determine the feasibility and results of targeted screening by general practitioners.
  
  
  METHODS
  For 2 weeks, 58 general practitioners systematically asked all their patients about a past (or current) history of intravenous drug use or transfusion of blood products before 1991. In patients who responded affirmatively, hepatitis C virus screening was proposed if it had not been performed previously.
  
  
  RESULTS
  8,292 patients were included. Blood transfusion and intravenous drug use were present in 383 (4.6%) and 116 (1.4%) patients respectively. Positive hepatitis C virus serology had been identified before the study, in 16 and 63 patients in these groups respectively. Tests were performed in 77% and 50% of patients with a history of blood transfusion and intravenous drug use. Systematic screening showed a positive hepatitis C virus serology in 7 and 4 patients with a history of blood transfusion and intravenous drug use (representing 2% and 15% of the tests performed during the study). Globally, 79 (88%) of the 90 patients with a positive serology had been identified before this systematic screening.
  
  
  CONCLUSIONS
  Systematic targeted screening of hepatitis C virus infection only results in a diagnosis in a few cases. In the patients who consulted a general practitioner, 70% and 94% of cases of hepatitis C in patients with a history of blood transfusion or intravenous drug use respectively, were known before systematic screening.
