BackgroundAcute psychiatric wards manage patients whose actions may threaten safety (conflict). Staff act to avert or minimise harm (containment). The Safewards model enabled the identification of ten interventions to reduce the frequency of both.ObjectiveTo test the efficacy of these interventions.DesignA pragmatic cluster randomised controlled trial with psychiatric hospitals and wards as the units of randomisation. The main outcomes were rates of conflict and containment.ParticipantsStaff and patients in 31 randomly chosen wards at 15 randomly chosen hospitals.ResultsFor shifts with conflict or containment incidents, the experimental condition reduced the rate of conflict events by 15% (95% CI 5.6–23.7%) relative to the control intervention. The rate of containment events for the experimental intervention was reduced by 26.4% (95% CI 9.9–34.3%).ConclusionsSimple interventions aiming to improve staff relationships with patients can reduce the frequency of conflict and containment.Trial registrationIRSCTN38001825.

The MAP can serve as a core research instrument with additional outcome measures added as required. The collection of a set of reliable quantitative measures of problems among drug and alcohol users by research or treatment personnel for outcome evaluation purposes need not be time-consuming.

We suggest that drug misusers and those working with drug misusers need to be more alert to the risks of polydrug use, including the combined use of alcohol with illicit drugs. The study revealed inconsistencies in the recording of drug-related deaths on death certificates. The routine recording of all substances detected during toxicological examination would improve the accuracy of death certification.

L. A review and meta-analysis of the patient factors associated with psychiatric in-patient aggression.Objective: To combine the results of earlier comparison studies of inpatient aggression to quantitatively assess the strength of the association between patient factors and i) aggressive behaviour,ii) repetitive aggressive behaviour. Method: A systematic review and meta-analysis of empirical articles and reports of comparison studies of aggression and non-aggression within adult psychiatric in-patient settings. Results: Factors that were significantly associated with in-patient aggression included being younger, male, involuntary admissions, not being married, a diagnosis of schizophrenia, a greater number of previous admissions, a history of violence, a history of self-destructive behaviour and a history of substance abuse. The only factors associated with repeated in-patient aggression were not being male, a history of violence and a history of substance abuse. Conclusion: By comparing aggressive with non-aggressive patients, important differences between the two populations may be highlighted. These differences may help staff improve predictions of which patients might become aggressive and enable steps to be taken to reduce an aggressive incident occurring using actuarial judgements. However, the associations found between these actuarial factors and aggression were small. It is therefore important for staff to consider dynamic factors such as a patient's current state and the context to reduce in-patient aggression. Summations• Psychiatric in-patients who are younger, male, admitted involuntarily, not married, have a diagnosis of schizophrenia, have a greater number of previous admissions, a history of violence, a history of self-destructive behaviour and a history of substance abuse were more likely to be aggressive than non-aggressive during their stay.• Psychiatric in-patients who are female and have a history of substance abuse or a history of violence were more likely to be repetitively aggressive than aggressive once during their stay. Considerations• The associations between patient characteristics and aggression were small suggesting that other factors may be helpful in predicting aggression.• There were significantly high levels of heterogeneity across the articles entered into most of the metaanalyses.• A relatively small number of comparison studies were found relative to the number of publications on in-patient aggression suggesting that this is an underused study design.
