Long-term Benzodiazepine Treatment in Patients with Psychotic Disorders Attending a Mental Health Service in Rural Greece

INTRODUCTION Long-term benzodiazepine (BZD) treatment in patients with mental disorders is widespread in clinical practice, and this is also the case of patients with schizophrenia, although the evidence is weak and BZD prescription is discouraged by guidelines and medical authorities. Data on BZD prescription are usually derived from national or regional databases whereas information on the use of BZD by patients with schizophrenia and related psychoses in general population-based samples is limited. MATERIALS AND METHODS Information for 77 patients with psychotic disorders who were regularly attending follow-up appointments with the multidisciplinary Mobile Mental Health Unit of the prefectures of Ioannina and Thesprotia, Northwest Greece, during 1-year period (2015) was obtained from our database. RESULTS From the total of 77 engaged patients, 30 (39%) were regularly prescribed BZDs in the long term, as part of their treatment regimen. Prescribed BZDs were mostly diazepam and lorazepam, in 43.3% of cases each. The mean daily dose of these compounds was 13 mg and 3.77 mg, respectively. Statistical analysis showed a correlation of long-term BZD use with the history of alcohol/substance abuse. Most patients were receiving BZD continuously for several years, and the mean dose was steady within this interval. CONCLUSIONS A large proportion of patients with psychotic disorders were regularly prescribed BZD in long term. It appears that when BZDs are prescribed for some period in the course of a psychotic disorder, their use commonly exceeds the recommended interval and then becomes a regular part of the chronic treatment regimen. Future research should address the factors that may be related to the long-term BZD use by patients with psychotic disorders. Interventions for the reduction of regular BZD prescription should target the primary care setting and all those who treat first episode patients.
