The aim of this study is to describe the patterns of prescription of benzodiazepine-receptor agonists in hospitalised patients in four psychogeriatric units in Switzerland. This is a retrospective cross-sectional study that included patients aged 65 years or more hospitalised in one of the four psychogeriatric units of a university hospital in Switzerland during 2019. The presence, type and dose of benzodiazepine-receptor agonists was assessed at admission and at discharge. Three-hundred and eighty-six patients (214 women, 78.2 ± 8.1 years) were included in the study; 33.4% of patients had at least one benzodiazepine-receptor agonist at admission and 22.5% at discharge. The relative reduction of benzodiazepine-receptor agonists prescription in standardised dose was 78%. Age was found to be a protective factor against benzodiazepine-receptor agonists prescription at admission (adjusted odds ratio 0.94, confidence interval 0.91-0.98), and diagnosis of substance abuse was found to be a risk factor (adjusted odds ratio 4.43, confidence interval 1.42-17.02). Longer hospital stays (> 14 days) were associated with higher reduction of benzodiazepine-receptor agonists. The prevalence of a prescription of benzodiazepine-receptor agonists at admission was high, but during the psychogeriatric hospitalisation benzodiazepine-receptor agonists prescription decreased both in absolute and relative terms.
