Background and study aims
Conflicts and aggression incidents occur frequently on psychiatric hospital wards. In general professionals try to calm down the situations with communication methods. As a last resort, coercive measures are applied. Due to legal and ethical reasons coercive measures are used restrictively. Professionals regularly receive training to manage aggression incidents and coercive measures. However, training mostly focuses on situations which are in an advanced state of escalation. Often they aim to enable a clear procedure in the case of overpowering and a controlled approach in the case of coercive measure. The procedures aim to resolve the situation in the least damaging way, both for the patients and for the employees. The Safewards model explains how aggression incidents, violence and coercive measures and their influencing factors are linked. According to the model, professionals should intervene much earlier in the process of escalation, and that a good relationship and communication skills as well as safe atmosphere on psychiatric wards may improve the prevention of aggression and coercive measures. Ten interventions were developed and tested successfully in a big study in psychiatric wards around London. Another effort on this topic was the developed of a scale (the Bern Psychopathology Scale (BPS)) by a research group in Bern. This scale helps to identify illness symptoms of three relevant communication domains (affectivity, language and motor behavior). With this information, professionals can focus their communication on the healthy domain. The idea is to avoid misunderstandings potentially leading to aggressions and violence. However, the effectiveness of this communication approach at reducing aggression and coercion has not been investigated before. Moreover it is unclear whether the Safewards interventions are effective in Swiss psychiatric wards. The aim of this study is to test the Safewards intervention in Swiss psychiatric wards and for the first time, communications training based on the mentioned Bern psychopathology scale.
Who can participate?
Staff and patients in acute psychiatric wards
What does the study involve?
Participating wards are randomly allocated either to the Safewards intervention group or the control group (treatment as usual). Both interventions focus on the training of the professionals. Patients are not actively involved, but they receive potentially better care due to better trained staff. The Safewards intervention includes the training and support of the staff during the implementation of the ten Safewards interventions. These include simple behaviour recommendations and training for the employees on the subject of conflict management, and measures for improving the relationships among patients as well as among the professionals in the normal daily life and when problems arise. All interventions and support measures are described comprehensively on the website www.safewards.com. The scale-based communication training includes training the employees how to assess patients with the BPS Scale as well as assistance and support in the training of communication strategies. The staff of the two control wards receive brief oral and written information on aggression and coercion. The intervention phase lasts 4 to 12 months. The number of aggression events and the use of coercive measures are recorded. Group interviews with patients and staff take place on the intervention wards at the end of the training or intervention in order to gain a better understanding of their experiences.
What are the possible benefits and risks of participating?
Because the interventions are staff-related and the intervention focuses on minimising the risks of aggression incidents and coercive measures, no direct risks are expected. In case of ineffective interventions the usual risks of a psychiatric in-patient treatment can be expected, which are unrelated to the interventions. It is possible that individual patients consider individual interventions like a mutual help meeting (an example of a safewards intervention) as not helpful or that they reject them, as is usual in mental health practice.

| Scientific title | A project to deal with and reduce coercion and aggression on acute psychiatric wards |
| Study acronym | ACR-Study |
| Study objectives | On acute psychiatric wards, where the Safewards intervention or BPS intervention are implemented, the frequency of coercion and aggression events will decrease during and after the implementation phase in comparison to the control group |
| Ethics approval(s) | Ethics Board of the canton of Berne (Switzerland, swissethics), 16/09/2016, Quantitative Part of the Study: Reg-2016-00513; Qualitative Part of the Study: Reg-2017-00846 |
| Health condition(s) or problem(s) studied | Coercion and aggression on acute psychiatric wards |
| Intervention | Stratified cluster randomisation was used. The six recruited wards were divided up in two as equal as possible groups regarding the length of average stay, frequency of involuntary admissions and number of seclusion rooms. Then from each group there was a concealed allocation to the following three groups: 1st Intervention: Training and supporting the staff to implement the 10 Safewards interventions. These include simple behavioural tips and training for staff on the topic of de-escalation and conflict management, activities to improve the relationship between patients and staff in everyday life and in problem situations like: weekly support conferences, systematic supportive conversations before or after negative events, as well as hopeful actions regarding the current, but also future situation of the patients, for example with the hopeful discharge messages from patients leaving the ward. All interventions are comprehensively described on the website www.safewards.com. 2nd Intervention: Training and supporting of staff implementing of the communication strategies based and focused on the domains of the Bern Psychopathology Scale (BPS). The BPS is a clinical rating scale developed to group psychotic symptoms in the domains of language, affectivity and motor behavior. These domains are of particular interest for understanding the fundamental communication breakdown during psychotic disorders, since they can be linked to known, higher order brain systems, i.e. the language, the limbic and the motor system. The intervention gives a training to recognize the well-functioning domain and to focus the communications skills on this domain. Control: Short verbal and written information on the topic of coercion and aggression as well as attaching pictures to aims and intervention of the project at the corresponding wards. Follow-up measures are planned for all arms 6 months after finishing the implementation of the interventions. |
