title: Adverse events due to change in organization of problem drug users' treatment?
abstract: OBJECTIVE
  This study set out to identify any undesirable consequences of legislative change in the organization of the treatment of problem drug users (PDUs), which aimed to combine their social and medical care.
  
  
  METHODS
  The method used was a register-based three-year follow-up prevalent cohort study.
  
  
  RESULTS
  On 1 January 1996, the law was changed to allocate unambiguous and undivided responsibility for the combined social and medical care of PDUs in Denmark. The main objective of the legislative change was to move PDUs from treatment by general practitioners (GPs) and at private clinics to treatment institutions under the control of the counties. The possibility remained that medical treatment could, however, continue to be given by GPs or private clinics, based on specific agreements. The study showed that at the end of the period, 31 December 1998, two-thirds remained in treatment at private clinics or at GP surgeries. During the period only 8% of users were at some time without methadone treatment; 2% remained without methadone treatment throughout the study period.
  
  
  CONCLUSIONS
  The transition from GPs and private clinics to the county treatment centres went smoothly. The number of PDUs in MMT (methadone maintenance treatment) in the city of Copenhagen increased in the period 1995 to 1998. The average quantity of methadone given to the cohort increased during these years from 72 mg per day to 92 mg per day. The legislative change therefore did not result in a higher threshold for treatment or a more restrictive prescription of methadone. No adverse effect on crime, hospital admissions, or death could be attributed to the legislative change in treatment organization.
