Nationwide trends in psychiatric prescription practices for drugs with putative cognitive adverse effects in schizophrenia spectrum and bipolar disorders from 2013 to 2022.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The management of schizophrenia spectrum (SZ) and bipolar disorders (BD) can involve psychotropic polypharmacy, high psychotropic doses, a high anticholinergic burden, and the use of anticholinergic agents and benzodiazepines, which are associated with poorer cognitive performance. We evaluated trends in those prescription practices in adult outpatients with SZ or BD between 2013 and 2022, to guide future treatment guidelines and interventions for improving cognition. Methods: We performed a retrospective longitudinal analysis of the nationwide French health claims database. We identified the deliveries of psychotropic drugs (antipsychotics, antidepressants, anxiolytics, hypnotics, and antiepileptics) occurring between 2013 and 2022. We estimated mixed-effects linear regression models of the number of psychotropics prescribed, the total daily dose/DDD of psychotropics, cumulative anticholinergic burden, and the frequencies of benzodiazepine and anticholinergic agent use across diagnoses and age groups. Results: Between 2013 and 2022, we measured small but significant declines in the number ( Conclusion: The slight decrease in the number and total dose of psychotropic drugs and the deliveries of benzodiazepines from 2013 to 2022 suggest a better consideration of adverse effects in adults with SZ or BD. However, the use of anticholinergic agents and the anticholinergic burden did not consistently decrease, suggesting that prescribers fail to reduce anticholinergic burden. Efforts to support deprescribing are further required after the pandemic.
