Predicting aggressive behaviour in acute forensic mental health units: A re-examination of the dynamic appraisal of situational aggression's predictive validity

The risk assessment of imminent inpatient aggression: A cross-cultural validation study of the dynamic appraisal of situational aggression in Estonia

INTRODUCTION

The reason for this study was void of a data-driven imminent risk assessment instrument for aggression in psychiatry clinics in Estonia. The predictive accuracy of the observer-rated Dynamic Assessment of Situational Aggression (DASA) has been repeatedly demonstrated. However, the research gap remains regarding a deeper conceptual understanding of the underlying latent structure of the DASA.

AIM

Comprehensively evaluate the psychometric properties of the Estonian DASA version for cross-cultural clinical use.

METHOD

We used a prospective repeated measure design and collected 6097 risk evaluations from 381 adult inpatients, 151 of whom committed 1013 aggressive incidents during the study.

RESULTS

The Estonian DASA version has acceptable inter-rater reliability (Kendall's τ = 0.74) and is a useful instrument with excellent predictive validity (AUC = 0.86) for identifying potentially aggressive inpatients. In our sample, the DASA has a bi-factorial structure which explains 83% of the total variance.

DISCUSSION

The adapted DASA has acceptable validity and reliability indices for measuring imminent aggression risk in adult inpatient units.

IMPLICATIONS FOR PRACTICE

Evidence-based risk assessment of aggression in psychiatric clinics enhances recognition of the signs of potentially aggressive behaviour in order to apply preventive actions and reduce aggression, thereby improving the quality of the care provided.

Developing entrustable professional activities to enhance application of an aggression prevention protocol

AIM

The research aim of this study was to seek feedback from prevention of aggression training experts about the suitability of Entrustable Professional Activities (EPAs) as an assessment tool for an Aggression Prevention Protocol. The protocol was designed to structure intervention to prevent aggression and reduce the use of restrictive practices following risk assessment using a validated instrument (the Dynamic Appraisal of Situational Aggression).

BACKGROUND

Preventing aggression and limiting the use of restrictive practices are key priorities for inpatient mental health services. Assessing clinical activities using a competence framework has limitations, particularly when determining complex interventions. EPAs could provide a suitable method for assessing complex clinical activities like de-escalation and limit setting, which comprise some of the interventions in the Aggression Prevention Protocol. EPAs are new to forensic mental health nursing; therefore, feedback was sought regarding the utility of EPAs to assess aggression prevention interventions.

METHODS

Data were collected via focus groups including 11 aggression prevention experts from Australia and New Zealand. A thematic analysis, comparative analysis and a Strength, Weakness, Opportunity and Threats analysis was conducted.

RESULTS

Three themes were interpreted from the data: 1) Frameworks such as the APP are needed to work towards elimination of restrictive practices; 2) APP-EPAs afford an opportunity to set the standard for practice; and 3) 'who watches the watchers', were identified by the experts as well as areas to enhance EPAs prior to introduction into practice.

CONCLUSIONS

EPAs address a practice-gap and offer a framework to assist movement towards elimination of restrictive practices, while prompting best-practice, self-reflection and practice improvement guidance.

Safewards: An integrative review of the literature within inpatient and forensic mental health units

Mental health inpatient units are complex and challenging environments for care and treatment. Two imperatives in these settings are to minimize restrictive practices such as seclusion and restraint and to provide recovery-oriented care. Safewards is a model and a set of ten interventions aiming to improve safety by understanding the relationship between conflict and containment as a means of reducing restrictive practices. To date, the research into Safewards has largely focused on its impact on measures of restrictive practices with limited exploration of consumer perspectives. There is a need to review the current knowledge and understanding around Safewards and its impact on consumer safety. This paper describes a mixed-methods integrative literature review of Safewards within inpatient and forensic mental health units. The aim of this review was to synthesize the current knowledge and understanding about Safewards in terms of its implementation, acceptability, effectiveness and how it meets the needs of consumers. A systematic database search using Medline, CINAHL, Embase and PsychInfo databases was followed by screening and data extraction of findings from 19 articles. The Mixed Methods Appraisal Tool (MMAT) was used to assess the quality of empirical articles, and the Johanna Brigg's Institute (JBI's) Narrative, Opinion, Text-Assessment and Review Instrument (NOTARI) was used to undertake a critical appraisal of discussion articles. A constant comparative approach was taken to analysing the data and six key categories were identified: training, implementation strategy, staff acceptability, fidelity, effectiveness and consumer perspectives. The success of implementing Safewards was variously determined by a measured reduction of restrictive practices and conflict events, high fidelity and staff acceptability. The results highlighted that Safewards can be effective in reducing containment and conflict within inpatient mental health and forensic mental health units, although this outcome varied across the literature. This review also revealed the limitations of fidelity measures and the importance of involving staff in the implementation. A major gap in the literature to date is the lack of consumer perspectives on the Safewards model, with only two papers to date focusing on the consumers point of view. This is an important area that requires more research to align the Safewards model with the consumer experience and improved recovery orientation.

Implementation of the dynamic appraisal of situational aggression in inpatient mental health

PURPOSE

To implement structured violence risk assessment (VRA) using the Dynamic Appraisal of Situational Aggression (DASA) on a 25-bed, adult, inpatient psychiatric unit.

DESIGN AND METHODS

Inpatient DASA screening for 13 weeks with nursing communication orders (NCOs) to highlight patients at high risk for violence. Pre/posttests measured registered nurse (RN) knowledge and perceptions of the DASA.

FINDINGS

DASA completion rate equaled 81.8% with an NCO issue rate of only 32.8%. RN perceptions of the DASA were positive, and knowledge of structured violence risk assessment increased.

PRACTICE IMPLICATIONS

Structured violence risk assessment with the DASA is feasible and well-accepted on psychiatric units.

A Clinical Decision Support System to Prevent Aggression and Reduce Restrictive Practices in a Forensic Mental Health Service

OBJECTIVE

Preventing aggression and reducing restrictive practices in mental health units rely on routine, accurate risk assessment accompanied by appropriate and timely intervention. The authors studied the use of an electronic clinical decision support system that combines two elements, the Dynamic Appraisal of Situational Aggression instrument and an aggression prevention protocol (eDASA+APP), in acute forensic mental health units for men.

METHODS

The authors conducted a cluster-randomized controlled trial incorporating a crossover design with baseline, intervention, and washout periods in a statewide, secure forensic mental health service. The study included 36 mental health nurses (13 men and 23 women, ages 20-65 years) with direct patient care responsibility and 77 male patients (ages 21-77 years) admitted to one of two acute mental health units during the baseline and intervention periods.

RESULTS

eDASA+APP implementation was associated with a significant reduction in the odds of an aggressive incident (OR=0.56, 95% confidence interval [95% CI]=0.45-0.70, p<0.001) and a significant decrease in the odds of administration of as-needed medication (OR=0.64, 95% CI=0.50-0.83, p<0.001). Physical aggression was too infrequent for statistical significance of any effects of eDASA+APP to be determined; however, incidents of physical aggression tended to be fewer during the eDASA+APP phase.

CONCLUSIONS

These results support the use of the eDASA+APP to help reduce incidents of aggression and restrictive practices in mental health units.

Using Q-methodology to explore mental health nurses' knowledge and skills to use recovery-focused care to reduce aggression in acute mental health settings

When nurses practise recovery-focused care, they contribute positively to the consumer's mental health recovery journey and empower the person to be actively engaged in the management of their illness. While using recovery-focused care is endorsed in mental health policy, many health professionals remain uncertain about its application with consumers who have a risk for aggression during their admission to an acute mental health inpatient setting. This paper reports on Australian research using Q-methodology that examined the knowledge and skill components of recovery-focused care that nurses use to reduce the risk for aggression. The data from forty mental health nurses revealed five factors that when implemented as part of routine practice improved the recovery outcomes for consumers with risk of aggression in the acute mental health settings. These factors were as follows: (I) acknowledge the consumers' experience of hospitalization; (II) reassure consumers who are going through a difficult time; (III) interact to explore the impact of the consumer's negative lived experiences; (IV) support co-production to reduce triggers for aggression; and (V) encourage and support consumers to take ownership of their recovery journey. These findings provide nurses with a pragmatic approach to use recovery-focused care for consumers with risk for aggression and contribute positively to the consumers' personal recovery.

Short-term risk assessments in an acute psychiatric inpatient setting: A re-examination of the Brøset Violence Checklist using repeated measurements - Differentiating violence characteristics and gender

This study investigated the association between short-term risk assessment measured by the Brøset Violence Checklist (BVC) and imminent violence using repeated measurements and differentiating violence characteristics and gender. All patients admitted to an acute psychiatric ward during one year (N = 528) were included. Logistic regression and generalized linear mixed model (GLMM) analyses were conducted. Results confirmed BVC's suitability for both male and female inpatients throughout their hospitalization also when differentiating threats and physical violence, and adjusting for diagnostic subpopulations and circadian variability. Results point to modified interpretations of the BVC sum scores. Future research should adjust for repeated measurements.

A tool to evaluate proportionality and necessity in the use of restrictive practices in forensic mental health settings: the DRILL tool (Dundrum restriction, intrusion and liberty ladders)

BACKGROUND

Prevention of violence due to severe mental disorders in psychiatric hospitals may require intrusive, restrictive and coercive therapeutic practices. Research concerning appropriate use of such interventions is limited by lack of a system for description and measurement. We set out to devise and validate a tool for clinicians and secure hospitals to assess necessity and proportionality between imminent violence and restrictive practices including de-escalation, seclusion, restraint, forced medication and others.

METHODS

In this retrospective observational cohort study, 28 patients on a 12 bed male admissions unit in a secure psychiatric hospital were assessed daily for six months. Data on adverse incidents were collected from case notes, incident registers and legal registers. Using the functional assessment sequence of antecedents, behaviours and consequences (A, B, C) we devised and applied a multivariate framework of structured professional assessment tools, common adverse incidents and preventive clinical interventions to develop a tool to analyse clinical practice. We validated by testing assumptions regarding the use of restrictive and intrusive practices in the prevention of violence in hospital. We aimed to provide a system for measuring contextual and individual factors contributing to adverse events and to assess whether the measured seriousness of threating and violent behaviours is proportionate to the degree of restrictive interventions used. General Estimating Equations tested preliminary models of contexts, decisions and pathways to interventions.

RESULTS

A system for measuring adverse behaviours and restrictive, intrusive interventions for prevention had good internal consistency. Interventions were proportionate to seriousness of harmful behaviours. A 'Pareto' group of patients (5/28) were responsible for the majority (80%) of adverse events, outcomes and interventions. The seriousness of the precipitating events correlated with the degree of restrictions utilised to safely manage or treat such behaviours.

CONCLUSION

Observational scales can be used for restrictive, intrusive or coercive practices in psychiatry even though these involve interrelated complex sequences of interactions. The DRILL tool has been validated to assess the necessity and demonstrate proportionality of restrictive practices. This tool will be of benefit to services when reviewing practices internally, for mandatory external reviewing bodies and for future clinical research paradigms.

Implementation of risk assessment tools in psychiatric services

Violence remains a major risk management concern in psychiatric services with implications on the safety and well-being of patients, staff, and the public. Serious physical and psychological consequences of violence involving property damage, bodily injuries, and threat to life have been reported in mental health services. Risk assessment tools are important safeguard measures; however, research on clinical implementation is presently limited. Structured professional judgment (SPJ) risk management tools that incorporate professional discretion with analytical understanding of evidence-based risk factors are widely accepted for risk assessment. However, clinical utility is suboptimal due to several barriers, including those related to the tool, the clinical setting, and resistance from health professionals. To better understand the challenges militating against optimal implementation of risk assessment tools, we reviewed and presented some lessons from the implementation of clinical practice guidelines on a general scale and our experience implementing an SPJ tool called Hamilton Anatomy of Risk Management across a variety of psychiatric services. In summary, the clinical utility of risk assessment tools improves if the tool is psychometrically sound, concise, consensus rated, time efficient, and practical for planning risk management. User feedbacks on the tool utility are also important to sustain implementation.

Evaluating the impact of an electronic application of the Dynamic Appraisal of Situational Aggression with an embedded Aggression Prevention Protocol on aggression and restrictive interventions on a forensic mental health unit

Risk assessment is a pre-requisite for violence prevention in mental health settings. Extant research concerning risk assessment and nursing intervention is limited and has focused on the predictive validity of various risk assessment approaches and instruments, with few attempts to elucidate and test interventions that might prevent aggression, and reduce reliance on coercive interventions. The integration of risk assessment and violence prevention strategies has been neglected. The aim of this feasibility study was to test a novel Aggression Prevention Protocol designed to prioritize the instigation of less restrictive interventions on an acute forensic mental health unit for female patients. A prospective quasi-experimental study was designed to test an Aggression Prevention Protocol, linked to an electronic application of the Dynamic Appraisal of Situational Aggression (DASA). Following introduction of the DASA and Aggression Prevention Protocol, there were reductions in verbal aggression, administration of Pro Re Nata medication, the rate of seclusion, and physical and mechanical restraint. There was also an increase in documented nursing interventions. Overall, these results support further testing of the electronic application of the DASA and the Aggression Prevention Protocol.

Changing practice using recovery-focused care in acute mental health settings to reduce aggression: A qualitative study

Consumer aggression is common in acute mental health settings and can result in direct or vicarious psychological or physical impacts for both consumers and health professionals. Using recovery-focused care, nurses can implement a range of strategies to reduce aggression and empower consumers to self-regulate their behaviour, when faced with challenging situations, such as admission to the acute care setting. Currently, there is limited literature to direct nurses in the use of recovery-focused care and how it can be used to reduce consumer aggression. Twenty-seven mental health nurses participated in this study. The constructivist grounded theory method guided data collection and analysis to identify categories that accurately described participants' experiences. Five categories emerged that described how nurses can implement recovery-focused care clinically to reduce the risk of consumer aggression: (i) identify the reason for the behaviour before responding; (ii) being sensitive to the consumer's trigger for aggression; (iii) focus on the consumer's strengths and support, not risks; (iv) being attentive to the consumer's needs; and (v) reconceptualize aggression as a learning opportunity. As the importance of promoting consumer recovery is now embedded in mental health policies internationally, nurses need to prioritize the application of recovery-focused care clinically. Further research to provide evidence-based outcomes supporting the use of recovery-focused care is needed.

Evaluating the Introduction of the Safewards Model to a Medium- to Long-Term Forensic Mental Health Ward

Care and treatment in forensic mental health wards can present with challenges when loss of hope and freedom, and aggression are present, which can then influence ward atmosphere and feelings of safety. Safewards is a model designed to address a range of conflict (e.g., aggression and self-harm) and containment (e.g., use of restrictive interventions) events and may provide a suitable approach to delivery of care in a forensic setting, while also addressing aggression, restrictive interventions, and ward atmosphere. The aim of this study was to evaluate the introduction of Safewards to a forensic mental health ward to determine suitability, and to explore if changes to conflict, containment, and ward atmosphere occurred. A mixed methods approach was used involving the collection of incident data related to conflict and containment, an assessment of the degree to which interventions were implemented, and an assessment of the social climate before and after implementation. Results suggested that there were fewer conflict events after Safewards was introduced; however, there did not appear to be any changes in the already low use of restrictive interventions. The Safewards interventions were implemented to a high degree of fidelity, and there was indication of an increase in a positive perception of ward atmosphere, supported by themes of positive change, enhanced safety, and respectful relationships. Safewards may assist in contributing to an improvement in the perception of ward atmosphere. To enhance implementation in a forensic mental health setting, there may be a need to consider additional elements to Safewards, pertinent to this setting.
