NCT03584542

Brief Summary

For several years, the French Addictovigilance Network (FAN) highlights potential problematic consumptions with zolpidem. To prevent abuse and misuse of zolpidem, the French Health Products Agency has changed the regulatory framework of zolpidem prescription. Thus, since the 10th of April 2017 zolpidem prescriptions have to be secured (particular support, dosage written out). The investigators hypothesized that this change will affect zolpidem consumption but also the consumption of all sedative drugs. In order to assess the incidence of the regulatory change for zolpidem prescription the investigators conduct a two part study: an epidemiological study with French National Health Insurance Fund for Employees database and an observational study with general practitioners and zolpidem consumers.

Outcome Measures

Primary Outcomes (1)

  • Prevalence of zolpidem consumers and substance use disorders with zolpidem (according to the number of DSM 5 criteria) before and after the regulatory prescription change

    The impact of regulatory prescription change of zolpidem will have a pleiotropic impact which can't be evaluated on a single criterion. It must be considered in a global, multifocal manner. This is why several criteria will be used to assess several incidence and several populations. These different approaches will enable us to respond to three questions * What is the impact on the number of consumers? * What is the impact on consumption patterns of zolpidem? * What is the impact on consumtion of other sedative drugs?
