Prevalence and Appropriateness of Antipsychotic Prescribing in an Italian Prison: Is Everything Always Really Overprescribed?

Purpose/Background: Although the prevalence of mental disorders in prisoners is known to be higher than in the general population, less is known about the antipsychotic (AP) prescribing rate in jail. The aim of this research was to investigate prevalence and appropriateness of AP prescription in an Italian prison to expand our understanding on this crucial area of clinical-forensic practice. Methods/Procedures: A cross-sectional (census day) design was used among male adults in the Parma Penitentiary Institutes (PPI). Sociodemographic, clinical and prescription data were collected from the PPI electronic clinical database management system. The AP prescribing appropriateness was examined in accordance with the therapeutic indications included in the Italian National Formulary. A descriptive statistical analysis was performed. Findings/Results: A total of 98 (14.1%) of 696 PPI prisoners were taking AP medications. Moreover, 90 (91.8%) of the 98 PPI participants were also taking other psychotropic medications concurrently. Quetiapine and olanzapine were the most common prescribed APs. Antipsychotic medications were most likely to be prescribed for off-label indications (74.4%). Less than one fifth of all AP prescriptions were for psychotic disorders. Implications/Conclusions: Antipsychotic medications are widely used in prison, often together with other psychotropic drugs. Considering their common adverse effects, it is crucial to longitudinally monitor their potential risk of metabolic, cardiovascular, and extrapyramidal symptoms and signs, as well as their early risk of mortality. Given the high prevalence of AP off-label prescription, the rationale for AP prescribing should be clearly documented and regularly reviewed within the prison by mental health professionals.
