Sedatives and analgesics are major contributors to potentially inappropriate duplicate prescriptions in geriatric psychiatry.

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
backgroundThis study sought to investigate the frequency and characteristics of duplicate prescriptions (DPs) in elderly psychiatric inpatients using a novel categorisation of DPs that differentiates between appropriate duplicate prescriptions (ADPs) and potentially inappropriate duplicate prescriptions (PIDPs).
methodsThe study was conducted as a monocentric retrospective cross-sectional pilot study on the gerontopsychiatric ward of the Department of Psychiatry, Social Psychiatry and Psychotherapy of Hannover Medical School, a large university hospital in northern Germany. The outcome measures were the nature and frequency of PIDPs compared with the frequency of ADPs.
resultsFor 92 individual patients a total of 339 medication chart reviews were conducted between April 2021 and February 2022. The median age of the study population was 73 years (interquartile range (IQR) 68-82 years); 64.6% were female. Patients' medications comprised a median of eight drugs (IQR 6-11 drugs) and 43.1% of the study population were exposed to at least one PIDP (at least one grade-1 PIDP: 39.5%; at least one grade-2 PIDP: 5.0%; at least one grade-3 PIDP: 1.5%). Sedatives were most frequently responsible for grade-1 and grade-2 PIDPs, while grade-3 PIDPs were elicited exclusively by analgesics. Nearly half of the study population (49.0%) displayed at least one ADP.
conclusionEven though the clinical implications of PIDPs are not fully established to date, we recommend that physicians who treat elderly psychiatric patients pay special attention to PIDPs, especially PIDPs elicited by sedatives. Termination of PIDPs may prevent adverse drug reactions and save healthcare expenditures.
