Prevalence and Predictors of Mechanical Restraint in Involuntary Patients in an Open-Door Inpatient Psychiatric Unit.

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
backgroundMechanical restraint (MR) remains one of the most controversial interventions in psychiatry, particularly in involuntarily admitted patients. This study examined the prevalence and clinical predictors of MR in an open-door psychiatric unit in Spain, a context where national MR rates remain among the highest in Europe.
methodsA retrospective descriptive study of all involuntarily admitted patients (n = 81) was conducted in a 20-bed open-door acute psychiatric unit between June and December 2024. Sociodemographic, diagnostic, and treatment variables were extracted from electronic health records. Bivariate analyses based on exact tests and Firth penalized-likelihood logistic regression were used to identify independent correlates of MR.
resultsMR was applied in 14.8% of patients. In Firth penalized-likelihood multivariable analysis, schizophrenia was the strongest independent correlate of MR (odds ratio [OR] = 9.58, 95% confidence interval [CI]: 1.71-65.89, p = 0.010). Male gender showed a significant bivariate association but lost significance after adjustment. MR co-occurred with intramuscular psychotropic medication in 91.7% of cases.
conclusionsWithin this single-centre, exclusively involuntary cohort, care delivered in an open-door setting with structured de-escalation interventions was associated with a comparatively low rate of MR. Schizophrenia emerged as the strongest correlate of MR and may represent a priority target for prevention strategies. The results align with convergent evidence from German, Swiss, and Norwegian studies supporting the safety and effectiveness of open-door approaches, and provide the first Spanish data on MR in this model of care. These findings are preliminary and require confirmation in larger, multicentre samples.
