Aggression in an Australian forensic psychiatric hospital

Exposure to patient aggression and health outcomes for forensic mental health nurses: A cross-sectional survey

AIMS

The aims of the study were to determine the types and prevalence of forensic mental health nurse exposure to patient aggression and explore the impact of these exposures on their physical and mental health and work absences.

DESIGN

Cross-sectional survey conducted January to April 2020.

METHODS

All 205 nurses working in an Australian high-security inpatient forensic mental health hospital were invited to participate. An online survey included the Perception of Prevalence of Aggression Scale to measure respondent exposure to types of patient aggression, and the SF-36v2 to measure mental and physical health. Absence from work and other work and individual characteristics were also explored.

RESULTS

Sixty-eight respondents completed the survey. Verbal abuse was the most experienced aggression type, followed by physical violence and observing violence, patient self-harming behaviours and sexual violence. Nurses who worked in acute units experienced significantly more exposure to overall aggression than nurses in non-acute units. Higher level of aggression was associated with number of days sick leave taken and days off due to aggression or violence. Higher level of aggression was associated with poorer mental health, and patient self-harming behaviour was associated with poorer physical health.

CONCLUSIONS

Nurses in acute units experience higher levels of inpatient aggression and are therefore at increased risk of being impacted by the exposure. Findings indicate a psychological impact of exposure to frequent aggression and potential for an accumulative effect of exposure to traumatic events on nurse well-being. Nurses who are victim of, or witness, physical violence are most likely to take time off work.

IMPACT

This study provides further evidence that forensic mental health nurses are frequently exposed to various forms of patient aggression. For some nurses, this exposure to patient aggression negatively impacted their mental and physical health. Employing organizations should therefore prioritize provision of formal support for nurses. No patient or public contribution.

Reducing violence and aggression: a quality improvement project for safety on an acute mental health ward

Violence and aggression (V&A) are identified as an issue on mental health wards that negatively affect staff, patients, care delivery and safety. This project took place on a male acute mental health ward where V&A are known to be an issue with an average of 21.3 incidences per month in the 6 months preceding the project.The aim was to use QI (Quality Improvement) methodology to reduce incidences of V&A by 20% over a 4-month period. A root cause analysis was completed with staff, previous QI projects and literature on interventions for V&A were reviewed. Two changes were introduced via PDSA (plan, do, study, act) cycles; first was a safewards bundle including a training package, weekly emails and noticeboard displays, the second was safety crosses displayed on the ward.There was a reduction in incidences of V&A across the project, mean weekly incidences reduced from 2.5 at baseline audit to 2.0 at the end of the project. This equates to a 20% reduction in V&A. The project did result in an increase of safewards interventions recorded and staff ratings of ward safety improved. There was a statistically significant correlation found between incidences of V&A and rates of restrictive practices.Further analysis of the 20% reduction did not find a special cause variation, so results may be due to a common cause variation rather than the QI interventions. Safety crosses were not found to have an impact on rates of V&A, it is likely these need to be more embedded into communication about V&A on the ward. Potential confounding patient variables such as illicit drug use and history of V&A as well as staffing should be recorded and monitored in future projects. Recommendations to enhance further change should include regular meetings with both staff and patients to support open communication about the topic.

Exposure to workplace trauma for forensic mental health nurses: A scoping review

BACKGROUND

Forensic mental health is a challenging workplace, with nurses subject to various trauma exposures in their professional role.

OBJECTIVES

To identify the key concepts related to the nature, extent and impact of workplace trauma for forensic mental health nurses.

DESIGN

A scoping review, informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) tool.

METHODS

Sources of evidence were identified and assessed for inclusion using an explicit search strategy. Relevant information was extracted and synthesised to present a descriptive summary of existing evidence.

RESULTS

Of the 16 articles on workplace trauma for forensic mental health nurses included in the review, nine reported data related to extent (incidence and severity) and 14 described the impact. The incidence (per bed/per year) of each workplace trauma type ranged from 0.95 - 7.15 for physical violence, 0.39-5.12 for verbal abuse, 0.03-0.12 for sexual violence, and 1.47-7.9 for self-harming behaviour. The proportion of incidents at the lowest severity rating ranged from 15.1% to 84.7%, and the range for the highest severity rating was 0% to 38.7%. In the single study that examined the incidence of vicarious trauma, 14.9% reported low levels and 27.7% reported high levels. Psychological distress was the most commonly reported impact of workplace trauma, identified in eight studies. Seven studies reported limited data for physical injury from workplace trauma. The impacts of exposure to workplace trauma reported in the remaining studies included needing to access psychological support, experiencing physiological symptoms, feeling less safe at work, and requiring time off work. With the exception of two studies providing limited data related to absenteeism, the impact for organisations was not explored in existing literature.

CONCLUSIONS

While studies indicated that forensic mental health nurses are frequently exposed to various forms of workplace trauma, reports of severe assaults on staff were rare. Although limited, these findings suggest that cumulative exposure to workplace trauma over time, or exposure to more severe forms of physical violence, increase forensic mental health nurse vulnerability to experiencing detrimental impacts on their personal and professional wellbeing.

Use of seclusion for managing behavioural disturbance in patients

Seclusion is a tool used by psychiatrists primarily to manage aggressive and disturbed behaviour that is presumed to be due to the patient's mental disorder. In most parts of the world there are guidelines to using seclusion that are designed to maximise a patient's freedoms and protect their liberty while providing a safe environment. Arguments against the use of seclusion revolve around the deprivation of liberty, the potential for misuse and the concept of seclusion as a form of social control, and patients generally report seclusion as a negative, coercive experience. There is little evidence that seclusion provides long-term benefits in terms of treating symptoms or reducing aggression, although the literature is mixed in this regard. Expert opinion recommends a combination of national policy, ward management and patient-centred interventions to reduce seclusion rates.

Aggression on inpatient units: Clinical characteristics and consequences

Aggression and violence are widespread in UK Mental Health Trusts, and are accompanied by negative psychological and physiological consequences for both staff and other patients. Patients who are younger, male, and have a history of substance use and psychosis diagnoses are more likely to display aggression; however, patient factors are not solely responsible for violence, and there are complex circumstances that lead to aggression. Indeed, patient-staff interactions lead to a sizeable portion of aggression and violence on inpatient units, thus they cannot be viewed without considering other forms of conflict and containment that occur before, during, and after the aggressive incident. For this reason, we examined sequences of aggressive incidents in conjunction with other conflict and containment methods used to explore whether there were particular profiles to aggressive incidents. In the present study, 522 adult psychiatric inpatients from 84 acute wards were recruited, and there were 1422 incidents of aggression (verbal, physical against objects, and physical). Cluster analysis revealed that aggressive incident sequences could be classified into four separate groups: solo aggression, aggression-rule breaking, aggression-medication, and aggression-containment. Contrary to our expectations, we did not find physical aggression dominant in the aggression-containment cluster, and while verbal aggression occurred primarily in solo aggression, physical aggression also occurred here. This indicates that the management of aggression is variable, and although some patient factors are linked with different clusters, these do not entirely explain the variation.

Safewards: the empirical basis of the model and a critical appraisal

ACCESSIBLE SUMMARY

In the previous paper we described a model explaining differences in rates of conflict and containment between wards, grouping causal factors into six domains: the staff team, the physical environment, outside hospital, the patient community, patient characteristics and the regulatory framework. This paper reviews and evaluates the evidence for the model from previously published research. The model is supported, but the evidence is not very strong. More research using more rigorous methods is required in order to confirm or improve this model.

ABSTRACT

In a previous paper, we described a proposed model explaining differences in rates of conflict (aggression, absconding, self-harm, etc.) and containment (seclusion, special observation, manual restraint, etc.). The Safewards Model identified six originating domains as sources of conflict and containment: the patient community, patient characteristics, the regulatory framework, the staff team, the physical environment, and outside hospital. In this paper, we assemble the evidence underpinning the inclusion of these six domains, drawing upon a wide ranging review of the literature across all conflict and containment items; our own programme of research; and reasoned thinking. There is good evidence that the six domains are important in conflict and containment generation. Specific claims about single items within those domains are more difficult to support with convincing evidence, although the weight of evidence does vary between items and between different types of conflict behaviour or containment method. The Safewards Model is supported by the evidence, but that evidence is not particularly strong. There is a dearth of rigorous outcome studies and trials in this area, and an excess of descriptive studies. The model allows the generation of a number of different interventions in order to reduce rates of conflict and containment, and properly conducted trials are now needed to test its validity.

Improving seclusion practice: implications of a review of staff and patient views

This review explores patient and staff perceptions and improvement suggestions regarding seclusion in psychiatric inpatient settings. After an extensive literature search, 39 empirical papers were included in the review. According to the literature, patients perceived seclusion to be a distinct negative incident. Staff thought seclusion had a therapeutic effect and believed that units could not operate effectively without seclusion, but regretted that the situation was not resolved differently. Staff and patients had suggestions to improve the seclusion experience. Common themes in relation to the implications for practice are the need for better communication and more contact between patients and staff before, during and after the seclusion event.

Inpatient verbal aggression: content, targets and patient characteristics

Verbally aggressive behaviour on psychiatric wards is more common than physical violence and can have distressing consequences for the staff and patients who are subjected to it. Previous research has tended to examine incidents of verbal aggression in little detail, instead combining different types of aggressive behaviour into a single measure. This study recruited 522 adult psychiatric inpatients from 84 acute wards. Data were collected from nursing and medical records for the first 2 weeks of admission. Incidents of verbal aggression were categorized and associations with patient characteristics examined. There were 1398 incidents of verbal aggression in total, reported for half the sample. Types of verbal aggression were, in order of prevalence: abusive language, shouting, threats, expressions of anger and racist comments. There were also a large number of entries in the notes which did not specify the form of verbal aggression. Staff members were the most frequent target of aggression. A history of violence and previous drug use were consistently associated with verbal aggression. However, there were also some notable differences in patient variables associated with specific types of verbal aggression. Future studies should consider using multidimensional measures of verbal aggression.

Benchmarking forensic mental health organizations

OBJECTIVE

This paper describes the forensic mental health forums that were conducted as part of the National Mental Health Benchmarking Project (NMHBP). These forums encouraged participating organizations to compare their performance on a range of key performance indicators (KPIs) with that of their peers.

METHOD

Four forensic mental health organizations took part in the NMHBP. Representatives from these organizations attended eight benchmarking forums at which they documented their performance against previously agreed KPIs. They also undertook three special projects which explored some of the factors that might explain inter-organizational variation in performance.

RESULTS

The inter-organizational range for many of the indicators was substantial. Observing this led participants to conduct the special projects to explore three factors which might help explain the variability - seclusion practices, delivery of community mental health services, and provision of court liaison services. The process of conducting the special projects gave participants insights into the practices and structures employed by their counterparts, and provided them with some important lessons for quality improvement.

CONCLUSIONS

The forensic mental health benchmarking forums have demonstrated that benchmarking is feasible and likely to be useful in improving service performance and quality.

Forensic psychiatric inpatients and aggression: an exploration of incidence, prevalence, severity, and interventions by gender

BACKGROUND

Previous investigations suggest that women judged to be not criminally responsible on account of mental disorder (NCR-MD) differ markedly from their male counterparts in important ways, underscoring the necessity of subsequent study.

OBJECTIVE

The goal of the present study was to inform our understanding of the presenting profile of female forensic psychiatric patients and contrast their risk of inpatient aggression with their male counterparts.

METHOD

The population of patients assessed and/or treated at a secure Canadian forensic psychiatric hospital were available for study. In total, 527 patients had complete data and were part of intensive retrospective file reviews; inpatient aggression was evaluated using the Overt Aggression Scale.

RESULTS

Women were no less likely than men to have a violent index offence and to perpetrate inpatient aggression. Examining the range of aggressive behaviours and severity levels did little to increase the relevance of gender to inpatient risk.

DISCUSSION

Female forensic patients represent a highly selected subgroup of women with exceptional clinical and behavioural challenges and associated treatment needs.

What's the point? Towards a methodology for assessing the function of psychiatric inpatient aggression

There are few examples in the literature of the application of functional analysis to psychiatric inpatient aggression. Structural assessment approaches have dominated. This paper introduces a system for classifying the functions of aggression in psychiatric inpatients that was applied to 502 aggressive behaviours exhibited by patients in a secure forensic psychiatric hospital. At least one function was identified for the majority of aggressive incidents; the most common functions pertaining to patients' responses to the restrictions and demands of the inpatient setting, to express anger or to punish others perceived as provocative, and to maintain status. There was little evidence suggesting that aggression was used to obtain tangible rewards, to reduce social isolation, or to simply observe the suffering of others. Differences in the function of aggressive behaviour were found across victim types. Results of this study have implications for the prediction and prevention of inpatient aggression and for the treatment of aggressive inpatients.

Clinician perceptions of personal safety and confidence to manage inpatient aggression in a forensic psychiatric setting

Inpatient mental health clinicians need to feel safe in the workplace. They also require confidence in their ability to work with aggressive patients, allowing the provision of therapeutic care while protecting themselves and other patients from psychological and physical harm. The authors initiated this study with the predetermined belief that a comprehensive and integrated organizational approach to inpatient aggression was required to support clinicians and that this approach increased confidence and staff perceptions of personal safety. To assess perceptions of personal safety and confidence, clinicians in a forensic psychiatric hospital were surveyed using an adapted version of the Confidence in Coping With Patient Aggression Instrument. In this study clinicians reported the hospital as safe. They reported confidence in their work with aggressive patients. The factors that most impacted on clinicians' confidence to manage aggression were colleagues' knowledge, experience and skill, management of aggression training, use of prevention and intervention strategies, teamwork and the staff profile. These results are considered with reference to an expanding literature on inpatient aggression. It is concluded that organizational resources, policies and frameworks support clinician perceptions of safety and confidence to manage inpatient aggression. However, how these are valued by clinicians and translated into practice at unit level needs ongoing attention.
