ABSTRACT

OBJECTIVES: France is the only European country with a dedicated addictovigilance network (French addictovigilance network [FAN]). However, the reporting of cases of abuse/dependence is insufficient. In an attempt to overcome this under-reporting, data from the medical information systems program (PMSI) is regularly used to identify cases. Since addictions are frequently associated with psychiatric comorbidities, a pilot study was conducted for the first time in a psychiatric hospital. It aims, through a PMSI request, to identify the sociodemographic characteristics and psychiatric diagnoses of patients consuming psychoactive substances (PAS) and the PAS types consumed. METHODS: This is a retrospective observational study conducted over a nine-month period at the psychotherapeutic center of Nancy (CPN). The codes used for the PMSI request are those of the international classification of diseases, tenth revision (ICD-10), codes F10 to F19 that characterize mental and behavioral disorders associated with the use of PAS. Cases presenting the four criteria necessary for an addictovigilance notification (1) identified notifier, (2) identified patient, (3) known consumed product (s) and (4) presence of an effect related to the abuse/dependence of PAS; were retained and analyzed. RESULTS: On an initial number of 252 cases, 82 cases of abuse/dependence were retained. The selected sample is predominantly male (67%). Cannabis (29%) and heroin (15%) are the most common illicit PAS. Regarding drugs, the consumption of benzodiazepines, a predominantly female phenomenon, is observed in 34% of subjects. Sixty-four per cent of the subjects were diagnosed "disorders related to the use of PAS", 14% as neurotic disorders, 9% as schizophrenia and 5% as of the mood disorders. CONCLUSION: This study identified a significant number of potentially reportable cases to the French Addictovigilance Network and demonstrated the interest of investigating cases of abuse/dependence in a psychiatric hospital.
