title: Methadone treatment practices and outcome for opiate addicts treated in drug clinics and in general practice: results from the National Treatment Outcome Research Study.
abstract: BACKGROUND
  General practitioners (GPs) are increasingly urged to become more involved in the care and treatment of drug misusers. Little information is available about the effectiveness of treatments delivered in primary health care or specialist settings. The impact of treatment setting is investigated as part of the National Treatment Outcome Research Study (NTORS). This is the largest study of treatment outcome for drug misusers ever conducted in the United Kingdom (UK).
  
  
  OBJECTIVE
  This paper presents six-month treatment outcomes for patients who received community-based methadone treatment in either a specialist drug clinic or a general practice setting.
  
  
  METHODS
  A prospective, multisite follow-up study of treatment outcome was conducted with 452 opiate addicts who had been given methadone treatment in primary health care and specialist clinic settings. Outcome data are presented for substance use behaviours, health, and crime.
  
  
  RESULTS
  Improvements at follow-up were found among both the GP and the clinic-treated groups in drug-related problems, health, and social functioning. Problems at intake were broadly comparable among the clinic-based and the GP patients. Similar levels and types of improvement were found for both groups at six-month follow-up.
  
  
  CONCLUSIONS
  Results demonstrate the feasibility of treating opiate addicts using methadone in primary health care settings, and show that treatment outcomes for such patients can be as satisfactory as for patients in specialist drug clinics. The GPs in our study are unrepresentative in their willingness to be actively involved with problem drug users; moreover, several services treated relatively large numbers of drug users. Issues surrounding the growth of 'GP specialists' are discussed.
