title: [Prescription of high dose buprenorphine by general practitioners].
abstract: BACKGROUND
  Since 1996, prescribing buprenorphine in high dosage as a drug maintenance treatment has been allowing French general practitioners to undertake drug addicts with a pharmacological support. In France, buprenorphine prescriptions seem to spread over general practitioners (buprenorphine was given to 74,300 patients in 2001). This paper assesses the different factors associated with buprenorphine prescription by general practitioners and with the different degrees of general practitioners' commitment in actually caring drug addicts with the help of buprenorphine.
  
  
  METHODS
  Two representative samples of private general practitioners, either prescribing buprenorphine (345 over a population of 876) or not prescribing (355 over a population of 1380) have been questioned through a phone interview in the department of South-Eastern France in November and December 2002. Samples have been constituted with the help of a random stratified survey according to sex, age and volume of services (acceptance rate: 65.5%). Survey data have been completed with general practitioners' activity data from Health Insurance and local socioeconomic data from Insee.
  
  
  RESULTS
  37.5% of general practitioners have at least once prescribed buprenorphine during the considered period, but only 26% of the prescribers treated 75% of patients. Prescribers are most often men, younger than 49 years, working in the fixed fees sector and having group practice. They are also most often members of a health care network, trained for drug maintenance treatments and, from an individual point of view, have relatives suffering cancer, or having HIV, or hepatitis C, or who are drug addicts. Low socioeconomic status of the area where GPs exert seems to be particularly associated with general practitioners' prescription of buprenorphine.
  
  
  CONCLUSIONS
  Data handled in this paper show that supply of substitutive treatments is concentrated among a reduced number of general practitioners and in particularly deprived geographic areas. Workload in deprived areas combined to great professional commitment in maintenance treatment reveals unexpected and unwanted specialisation behaviours by general practitioners, as well as more isolated behaviours by general practitioners who do not ask for particular training program or help by colleagues. These results question the consistency of the general framework of support to general practitioners proposed by health authorities with general practitioners actual practice and needs.
