Uncovering Complexities in Reducing Aggression, Conflict and Restrictive Practices in Acute Mental Healthcare Settings: An Overview of Reviews

Aggression, conflict and restrictive practices present complexities in acute mental health services, as do implementing service changes to reduce them. Existing published literature needs to offer more high-level guidance on the effectiveness of these service changes and their associated implementation factors. As a result, an overview of systematic reviews was undertaken to identify (i) nonpharmacological interventions to reduce conflict, aggression and restrictive practices in acute mental health settings, and (ii) their effects across different clinical outcomes. A parallel re-extraction from primary studies was then utilised (iii) to identify factors influencing successful intervention implementation. Of 124 articles sourced from nine databases and registries, four reviews were retained for the final analysis, using the direction of effect and tabular and narrative summaries. These reviews included programmes or interventions focused on inpatient adolescent, adult and older adult populations. They reported on alternative containment strategies, risk assessments, Safewards, sensory rooms and equipment, Six Core Strategy-based interventions and staff training. The overview found that a combination of interventions intended to improve relationships and reduce interpersonal conflict may help reduce aggression, conflict and restrictive practices. At the same time, stand-alone staff training and sensory rooms and equipment may have mixed effects. The quality of the evidence linking these interventions to reductions in aggression, conflict and restrictive practices is limited. Successful implementation hinges on multiple factors: intervention characteristics, preparation and planning, evaluation and monitoring, outcome interpretation, stakeholder involvement/investment, staff-related factors and contextual factors. Any implementation initiative may benefit from using pragmatic and complexity-informed research methodologies, including integrating meaningful involvement with service users, peer workers and culturally diverse groups.

A participatory and comprehensive intervention to improve violence prevention in two high-risk occupations: effect and process evaluation of a stepped wedge cluster randomised trial

BACKGROUND

Work-related violence committed by clients, patients, and customers represents a major occupational health risk for employees that needs to be reduced.

METHODS

We tested a comprehensive violence prevention intervention involving active participation of both employees and managers in the Prison and Probation Service (PPS) and on psychiatric wards in Denmark. We used a stepped wedge cluster randomised controlled trial design. We measured the degree of implementation of the intervention by registration of fidelity, reach, and dose and used a mixed-effects regression analysis to estimate the effects of the intervention.

RESULTS

We recruited 16 work units for the intervention, but three work units dropped out. The average implementation rate was 73%. In the psychiatric wards, the intervention led to statistically significant improvements in the primary outcome (an increase in the degree to which managers and employees continuously work on violence prevention practices based on their registration and experiences), but none statistically significant improvements in any of the secondary outcomes. In the PPS units, the intervention did not lead to a statistically significant improvement in the primary outcome, but to statistically significant improvements in three secondary outcomes.

CONCLUSION

Most work units were able to carry out the intervention as planned. The intervention showed mixed results regarding the primary outcome. Nevertheless, the results indicate improvements also in the sector where a change in the primary outcome was not achieved. The results point at that a participatory and comprehensive approach could be a viable way of working with violence prevention in high-risk workplaces.

Workplace's Development of Activities and Action Plans to Prevent Violence From Clients in High-Risk Sectors

INTRODUCTION

Interventions trying to prevent violence from clients towards employees tend to show limited effect on the risk or the frequencies of violent episodes, possibly due to a too-narrow focus on only one or a few preventive strategies. This study aimed to show what employees and line managers identify as key intervention areas for preventing violence and threats.

METHODS

The study is based on data collected during a participatory intervention study aiming to improve violence prevention in Danish psychiatric units and prison and detention centers. In the intervention study, employees and line managers from 13 work units developed 293 suggestions and 92 action plans to prevent workplace violence. Through qualitative thematic analysis of the suggestions and action plans, we identified the main categories that work units viewed as important and realistic to work with to improve violence prevention.

RESULTS

We identified 12 topics of violence prevention that work units considered relevant. Action plan topics used by more than half of the work units included: specific approaches to violence prevention (e.g., de-escalating techniques), communication between employees to transfer knowledge between shifts, and introduction to new employees and temporary workers. Topics used by three to five work units were: interdisciplinary corporation, communication and relational work, uniform approaches, organization of work, and staffing. Topics used rarely were: definition of violence and threats, policy and guidelines, support from colleagues and management, and engagement in violence prevention. For nine of the 12 topics, action plans were developed in both high-risk sectors.

CONCLUSIONS

The violence prevention action plans developed by work units from two high-risk sectors indicate that workplaces estimate the prevention of client-induced workplace violence to require activities on many levels and cannot be solved by a single focused approach. This variety of preventive activities needs to be considered when designing violence prevention interventions.
