De-escalation techniques for managing aggression

Agression en milieu psychiatrique fermé : identification des déclencheurs qui précèdent les agressions contre les intervenants

Cette étude vise l’identification des déclencheurs qui précèdent les agressions survenues dans un hôpital psychiatrique fermé. Une analyse de contenu de 140 rapports d’incident visant l’identification du déclencheur qui précédait immédiatement les événements d’agression survenus entre 2012 et 2017 a été effectuée. Avec un accord interjuge de 0,87, les résultats concordent avec ceux retrouvés dans des études précédentes. Plus de 37 % des agressions surviennent à la suite d’une intervention verbale d’un intervenant, alors qu’un peu plus de 54 % ont lieu à la suite d’un contact physique entre un intervenant et un patient. Moins de 9 % des agressions subies par le personnel sont liées à des événements où il a été impossible d’observer un déclencheur. Ces résultats sont discutés dans le cadre d’une approche interactionnelle sur l’agression en psychiatrie légale et ils permettent de proposer des pistes pour réduire le risque d’agression.

De-escalation techniques for managing non-psychosis induced aggression in adults

BACKGROUND

Aggression occurs frequently within health and social care settings. It can result in injury to patients and staff and can adversely affect staff performance and well-being. De-escalation is a widely used and recommended intervention for managing aggression, but the efficacy of the intervention as a whole and the specific techniques that comprise it are unclear.

OBJECTIVES

To assess the effects of de-escalation techniques for managing non-psychosis-induced aggression in adults in care settings, in both staff and service users.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL and 14 other databases in September 2017, plus three trials registers in October 2017. We also checked references, and contacted study authors and authorities in the field to identify additional published and unpublished studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs comparing de-escalation techniques with standard practice or alternative techniques for managing aggressive behaviour in adult care settings. We excluded studies in which participants had psychosis.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane.

MAIN RESULTS

This review includes just one cluster-randomised study of 306 older people with dementia and an average age of 86 years, conducted across 16 nursing homes in France. The study did not measure any of our primary or secondary outcomes but did measure behavioural change using three measurement scales: the Cohen-Mansfield Agitation Inventory (CMAI; 29-item scale), the Neuropsychiatric Inventory (NPI; 12-item scale), and the Observation Scale (OS; 25-item scale). For the CMAI, the study reports a Global score (29 items rated on a seven-point scale (1 = never occurs to 7 = occurs several times an hour) and summed to give a total score ranging from 29 to 203) and mean scores (evaluable items (rated on the same 7-point scale) divided by the theoretical total number of items) for the following four domains: Physically Non-Aggressive Behaviour, such as pacing (13 items); Verbally Non-Aggressive Behaviour, such as repetition (four items); Physically Aggressive Behaviour, such as hitting (nine items); and Verbally Aggressive Behaviour, such as swearing (three items). Four of the five CMAI scales improved in the intervention group (Global: change mean difference (MD) -5.69 points, 95% confidence interval (CI) -9.59 to -1.79; Physically Non-Aggressive: change MD -0.32 points, 95% CI -0.49 to -0.15; Verbally Non-Aggressive: change MD -0.44 points, 95% CI -0.69 to -0.19; and Verbally Aggressive: change MD -0.16 points, 95% CI -0.31 to -0.01). There was no difference in change scores on the Physically Aggressive scale (MD -0.08 points, 95% CI -0.37 to 0.21). Using GRADE guidelines, we rated the quality of this evidence as very low due to high risk of bias and indirectness of the outcome measures. There were no differences in NPI or OS change scores between groups by the end of the study.We also identified one ongoing study.

AUTHORS' CONCLUSIONS

The limited evidence means that uncertainty remains around the effectiveness of de-escalation and the relative efficacy of different techniques. High-quality research on the effectiveness of this intervention is therefore urgently needed.

De-escalation techniques for psychosis-induced aggression or agitation

BACKGROUND

Aggression is a disposition, a willingness to inflict harm, regardless of whether this is behaviourally or verbally expressed and regardless of whether physical harm is sustained.De-escalation is a psychosocial intervention for managing people with disturbed or aggressive behaviour. Secondary management strategies such as rapid tranquillisation, physical intervention and seclusion should only be considered once de-escalation and other strategies have failed to calm the service user.

OBJECTIVES

To investigate the effects of de-escalation techniques in the short-term management of aggression or agitation thought or likely to be due to psychosis.

SEARCH METHODS

We searched Cochrane Schizophrenia Group's Study-Based Register of Trials (latest search 7 April, 2016).

SELECTION CRITERIA

Randomised controlled trials using de-escalation techniques for the short-term management of aggressive or agitated behaviour. We planned to include trials involving adults (at least 18 years) with a potential for aggressive behaviour due to psychosis, from those in a psychiatric setting to those possibly under the influence of alcohol or drugs and/or as part of an acute setting as well. We planned to include trials meeting our inclusion criteria that provided useful data.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. Two review authors inspected all abstracts of studies identified by the search process. As we were unable to include any studies, we could not perform data extraction and analysis.

MAIN RESULTS

Of the 345 citations that were identified using the search strategies, we found only one reference to be potentially suitable for further inspection. However, after viewing the full text, it was excluded as it was not a randomised controlled trial.

AUTHORS' CONCLUSIONS

Using de-escalation techniques for people with psychosis induced aggression or agitation appears to be accepted as good clinical practice but is not supported by evidence from randomised trials. It is unclear why it has remained such an under-researched area. Conducting trials in this area could be influenced by funding flow, ethical concerns - justified or not - anticipated pace of recruitment as well the difficulty in accurately quantifying the effects of de-escalation itself. With supportive funders and ethics committees, imaginative trialists, clinicians and service-user groups and wide collaboration this dearth of randomised research could be addressed.
