Violent incidents on a medium secure unit over a 17-year period

An Evaluation of the Implementation of a "No Force First" Informed Organisational Guide to Reduce Physical Restraint in Mental Health and Learning Disability Inpatient Settings in the UK

BACKGROUND

The use of physical restraint on vulnerable people with learning disabilities and mental health problems is one of the most controversial and criticised forms of restrictive practice. This paper reports on the implementation of an organisational approach called "No Force First" within a large mental health organisation in England, UK. The aim was to investigate changes in violence/aggression, harm, and physical restraint following implementation.

METHODS

The study used a pretest-posttest quasi-experimental design. Recorded incidents of violence/aggression from 44 inpatient mental health and learning disabilities (including forensic) wards were included (n = 13,599). Two study groups were created for comparison: the "intervention" group comprising all incidents on these wards during the 24 months post-implementation (2018-2019) (n = 6,551) and the "control" group comprising all incidents in the 24 months preceding implementation (2015-2016) (n = 7,048). Incidents recorded during implementation (i.e., 2017) were excluded (n = 3,705). Incidence rate ratios (IRR) were calculated with 95% confidence intervals (95% CI). Multivariate regression models using generalised estimating equations were performed to estimate unadjusted and adjusted prevalence ratios (aPR) of physical restraint and harm, using type of wards, incident, and violence/aggression as key covariates.

RESULTS

A significant 17% reduction in incidence of physical restraint was observed [IRR = 0.83, 95% CI 0.77-0.88, p < 0.0001]. Significant reductions in rates of harm sustained and aggression/violence were also observed, but not concerning the use of medication during restraint. The prevalence of physical restraint was significantly higher in inpatients on forensic learning disability wards than those on forensic mental health wards both pre- (aPR = 4.26, 95% CI 2.91-6.23) and post-intervention (aPR = 9.09, 95% CI 5.09-16.23), when controlling for type of incident and type of violence/aggression. Physical assault was a significantly more prevalent risk factor of restraint use than other forms of violence/aggression, especially that directed to staff (not to other patients).

CONCLUSIONS

This is a key study reporting the positive impact that organisational models and guides such as "No Force First" can have on equipping staff to focus more on primary and secondary prevention as opposed to tertiary coercive practices such as restraint in mental health and learning disabilities settings.

A Predictive Model for Estimating Risk of Harm and Aggression in Inpatient Mental Health Clinics

Serious mental illness is a major risk factor for aggression and violence. The present study aimed to develop and test an algorithm to predict inpatient aggressions that involve a risk of harm to self or others. This work is based on a retrospective study aimed to investigate the prediction of risk of harm and aggressions at St. Joseph's Healthcare Hamilton, between 2016 and 2017. An analysis of the risk factors most strongly associated with harmful incidents is, followed by the description of the process involved in the development of a predictive model which estimates the risk of harm. The efficiency of the model developed is finally evaluated, showing an overall accuracy of 75%: the specificity to identify episodes considered not at risk of harm is equal to 91.85%, whereas the sensitivity to identify episodes considered harmful is equal to 28.57%. The model proposed can be seen as a seminal project towards the development of a more comprehensive, precise and effective tool capable to predict the risk of harm in the inpatient setting.

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.

Breaking down long-term chronic aggression within a forensic hospital system

OBJECTIVE

Historically, patients with multiple acts of aggression, or chronic aggressors, have been studied as one large group. It was our objective to subdivide this group into those patients who engage in physical aggression consistently over multiple years and see if common characteristics of chronic aggressors could classify patients into an aggressive or nonaggressive group.

METHOD

Within a forensic hospital system, patients who had committed 5 acts of physical aggression, per year, for 3 years (2010 and 2015) were reviewed. Data was collected on clinical and demographic characteristics that have shown to be associated with chronically aggressive patients and compared to nonaggressive matched controls. Data collection and analysis were completed to determine if the variables could classify patients into an aggressive or nonaggressive group.

RESULTS

Analysis showed that 2 variables, the presence of a cognitive disorder and a history of suicidal behaviors were significant in the univariate and multivariate analyses. The 2 variables were able to correctly classify 76.7% of the cases.

CONCLUSION

A cognitive disorder, a history of suicidal behavior, and increased age were factors associated with this subgroup of aggressive patients. Clinicians may want to explore treatment programs aimed at these clinical factors including cognitive rehabilitation and social cognition treatments, which have been shown to reduce aggression in cognitively impaired populations.

Risk Factors Associated With Inpatient Violence During Medium Security Treatment

Violence is a common phenomenon both in regular and forensic psychiatric settings, and has a profound impact on staff and other patients. Insight into the individual risk factors associated with violence in forensic psychiatric settings is rare and is therefore the subject of this research. A retrospective file study in three medium security units in Flanders was conducted to compare non-violent inpatients with inpatients who engaged in (verbal and physical) violent behavior. Binary logistic regression analyses were used to examine which variables contributed independently to the risk of violence. The results showed that absconding during treatment was independently associated with physical violence. A personality disorder diagnosis and general non-compliance with treatment were associated with verbal violence. Both types of violence predicted early termination of treatment. Contrary to previous research, the results from the risk assessment tools were not associated with inpatient violence. Clinical implications are discussed and include, among others, that clinicians should remain vigilant for early warning signs of non-compliance during treatment.

Critical incidents and judicial response during medium security treatment

This study examined inpatient incidents in three Flemish forensic medium security units and analyzed the subsequent judicial reactions to these incidents. During medium security treatment, incidents were reported for more than half of the participants. The most frequently registered incidents were non-violent in nature, such as absconding and treatment non-compliance. The base rate for physically violent incidents was low. Although crime-related incidents during medium security treatment were rarely prosecuted and adjudicated, the base rate of revocation - and hence drop-out from treatment - as a result of these incidents was high.

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.

Evaluation of anger management groups in a high-security hospital

BACKGROUND

Anger management programmes for offenders typically aim to improve the management of emotion associated with aggressive and antisocial behaviour. Such programmes have been quite extensively evaluated in prison and probation settings, but there is less published research in forensic mental health settings.

AIM

This study aimed to evaluate anger management groups in a high-security hospital.

METHOD

Eighty-six patients were referred for a 20-session anger management intervention. Outcomes were self-reported experiences of anger and changes in institutionally documented incidents of aggression. Incident rates were retrospectively reviewed for all group graduates, where data were available, including a comparison group of graduates who acted as their own controls.

RESULTS

Group graduates reported sustained reductions in feelings of anger and positive changes in their use of aggression in reaction to provocation. Some reduction in incidents of physical aggression was noted when group completers were compared with non-completers. Incidents of verbal aggression were observed to increase for graduates. There was also a trend towards improvement when treated men were compared with men on the waiting list.

CONCLUSIONS

Our findings contribute to the growing evidence for anger management groups for aggressive men, although the low-base rate of incidents, typical of such a containing and therapeutic hospital setting, rendered the analysis of behavioural outcomes difficult.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Anger management sessions for male forensic psychiatric patients can be effective in reducing incidents of physical aggression in response to provocation. Evaluation of treatments for anger is particularly difficult in secure and protective settings, where the aim is to keep incidents of actual physical aggression to a minimum. Further research of this kind is needed to test the value of self-reported reduction in angry feelings as an indicator of clinically useful progress.

A review of violent incidents in a multilevel secure forensic psychiatric hospital: is there a seasonal variation?

There have been several attempts made to reduce the occurrence of violence in hospital settings, with most professional organizations taking a stance. The impact of violent incidence on the therapeutic environment and the cost in human terms led to the declaration by the World Health Organization that violence is a public health problem. There are strategies for reducing violence that flow out of known trends. We sought to examine the trends in institutional violence in a contextual sense. We reviewed the records of all incidents of violence, categorized by severity, victims and trends over five years in a multilevel secure forensic hospital in Canada. The rate of violence perpetrated by female patients was significantly higher than for male patients. Higher occurrence of violence was recorded in the winter months compared with any other season and was related to unstructured activities. There is a window of opportunity to develop some engaging programmes during the long winter months and improve supervision at all times of unstructured activity. The reasons for increased women perpetration and the winter peak of violence require further investigation.

Factors associated with seclusion in a statewide forensic psychiatric service in Australia over a 2-year period

Despite seclusion being described as one of the most ethically- and legally-controversial management options available, it remains a widely-used clinical strategy for managing disruptive, aggressive, and violent behaviour. This study sought to determine how frequently seclusion was used, the common characteristics of those secluded and not secluded, and the degree to which the Level of Service Inventory - Revised: Screening Version (LSI-R: SV) could predict seclusion. The study was retrospective, covering the first 2 years of operation of a statewide forensic psychiatry hospital in Victoria, Australia. Data were collected from individual case files, electronic databases, and paper copies of records pertaining to violent incidents and episodes of seclusion. Eighty five (44%) of the 193 patients admitted during this period were secluded. Those secluded were significantly younger and had a more established psychiatric history. LSI-R: SV scores were significantly and positively associated with being secluded. A statistical model containing three LSI-R: SV items, along with age on admission and psychiatric history, achieved an area under the curve of 0.74. Seclusion is used on a regular basis in response to a range of different forms of aggressive behaviour of different severity. The LSI-R: SV demonstrated moderate-to-good accuracy in predicting seclusion and warrants further research using detailed prospective methodologies.

Junior staffing changes and the temporal ecology of adverse incidents in acute psychiatric wards

AIM

This paper reports an examination of the relationship between adverse incident rates, the arrival of new junior staff on wards, and days of the week on acute psychiatric wards.

BACKGROUND

Incidents of violence, absconding and self-harm in acute inpatient services pose risks to patients and staff. Previous research suggests that the arrival of inexperienced new staff may trigger more adverse incidents. Findings on the relationship between incidents and the weekly routine are inconsistent.

METHOD

A retrospective analysis was conducted of formally reported incident rates, records of nursing student allocations and junior doctor rotation patterns, using Poisson Regression. Variance between days of the week was explored using contingency table analysis. The data covered 30 months on 17 psychiatric wards, and were collected in 2002-2004.

FINDINGS

The arrival of new and inexperienced staff on the wards was not associated with increases in adverse incident rates. Most types of incidents were less frequent at weekends and midweek. Incident rates were unchanged on ward-round days, but increased rates were found on the days before and after ward rounds.

CONCLUSION

Increased patient tension is associated with raised incident rates. It may be possible to reduce incident rates by moderating stimulation in the environment and by mobilizing support for patients during critical periods.

The nurse's role in the management of aggression

Although research into the phenomenon of aggression within psychiatric inpatient settings has established a strong casual link with mental illness, there is widespread agreement that diagnostic or demographic characteristics cannot accurately predict such behaviours. In addition, studies have consistently failed to establish how nursing management responses influence the course of aggression within these environments. Therefore, an assumption can be made that specific contextual factors are significant, and that management responses have an effect on outcomes. This review examines the nurses' impact on inpatient aggression and how management strategies affect the therapeutic value of intervention.

A study of psychiatric nurses' beliefs and attitudes about work safety and assaults in Turkey

In Turkey, the cultural structure effects the gender roles in the society, and women are subject to violence in an intense manner both inside the family and in their workplaces. In nursing, which is still defined as a woman's job in our country, it is possible to encounter many aggressive and threatening behaviours. Knowing no geographical borders, aggression leads to dissatisfaction and alienation with the profession for the nurses working at the psychiatric institutions in Turkey, thus aggression is a significant health risk in physical, psychological and social dimensions. The research was carried out with 162 randomly selected nurses working in the psychiatric institutions in Istanbul using the Attitudes Toward Patient Physical Assault Questionnaire. It has been determined that nurses' rate of exposure to verbal/physical assault by the patients and their relatives is high and that they experience an intense uncertainty and conflict, especially in legal issues, and that the duration of working in the psychiatry clinics effects attitudes toward the assaults. It is concluded that the nurses working at the psychiatry clinics in Turkey are under risk in regards to safety and they need protection and support, both in emotional and in legal terms.

Social isolation, impulsivity and depression as predictors of aggression in a psychiatric inpatient population

Aggressive behavior among psychiatric inpatients remains an issue of concern for staff, families and patients themselves. At the present time, studies examining prediction of aggression among psychiatric inpatients have focused mainly on diagnostic or demographic risk factors. Unfortunately little is known about specific social functioning and personality risk factors that may help identify specific individuals at risk for aggressive behavior. Given that many individuals who have engaged in violent criminal behavior have been observed to experience a combination of social isolation, depression and impulsiveness, it is possible that this same combination of traits may function as a predictor of aggression among psychiatric inpatients. The current study examines whether psychiatric inpatients with a combination of social isolation, depression and impulsivity are significantly more likely to become aggressive than other psychiatric inpatients without that combination of factors. Results indicated that impulsivity functioned as a positive predictor of aggression, whereas depression acted as a protective factor. Perceived social support did not appear to relate strongly to aggression. Further, physicians' ratings of hostility were more predictive of aggressive incidents than were self-reports of hostility. Clinical implications of these findings are discussed.

Patient and nurse accounts of violent incidents in a medium secure unit

Most studies examining violence in a forensic setting have adopted a statistical approach to associate relevant predictors and the likelihood of violence. Views of patients and nurses have been a relatively neglected research area. This study explored patients' and nurses' accounts of violent incidents, considering similarities and differences in their narratives. Permission was obtained from the local National Health Service Research Ethics Board and the Research Ethics Committee of University of East London. Anonymized transcripts were produced from semi-structured interviews conducted in a Medium Secure Unit with four nurses and four patients, who consented to talk at length with the first author about violent events they had witnessed on the Unit. Grounded theory analysis of the data generated a core category, 'control', and five constituent themes: the construction of identity of the perpetrator of violence; nurses' dual role of caring and controlling; aspects of parentalism involved in control; following set policies and procedures; and segregation from mainstream society. Because of widespread social interest and media coverage in the topic, discursive examination was made of aspects of social context arising within the data. This study was small scale and exploratory, and further confirmatory research is needed. Nevertheless, clear contrasts between the nurse and patient accounts indicated tentative suggestions for training (including user involvement) and intervention in managing violent behaviour.

Management of psychiatric in-patient violence: patient ethnicity and use of medication, restraint and seclusion

BACKGROUND

Significant ethnic differences have been found previously on a forensic unit in the management of psychiatric patients after a violent incident.

AIMS

To study the management of violent incidents on all general wards in a large psychiatric hospital in South London. The main question is whether there are differences in the management of Black patients involved in violent incidents compared with White patients and, if so, what are the factors leading to it?

METHOD

All recorded violent incidents (1515 in total) on 14 general wards over three years (1994, 1996, 1998) were analysed using mixed logistic regression to estimate the odds ratio that the corresponding management decision (emergency medication, physical restraint, seclusion) was taken for Black patients compared with White patients after controlling for covariates and unobserved heterogeneity between subjects.

RESULTS

Black patients were more likely than White patients to be given emergency medication and to be secluded after a violent incident, but not to be physically restrained. However, differences disappeared when the odds ratios were adjusted for other variables.

CONCLUSIONS

Racial 'stereotyping' was unlikely to have played a major direct role in determining nurses' responses.

Differences in the progress of discharged and undischarged patients in a medium secure unit: a pilot study

This study compared 15 patients ('undischarged' group) who were showing little sign of progress in a medium secure unit (MSU) after 2 years with 15 who had been discharged from the same unit 1-2 years following admission. The two groups were compared across a number of broadly defined behavioural indices during their first 6 months and first 12 months following admission. The measures used were indices of progress to wards of lower security (highest ward status and transfers to wards of higher security) and progress in terms of leave (highest leave status and reductions in leave status). In addition, the two groups were compared on number of recorded incidents attributable to them. Discharged patients were significantly older at the time of their admission than the undischarged patients (median ages 33 and 26 years, respectively). They made more progress in their first year in terms of ward security and leave status and were responsible for fewer recorded incidents. These results were also obtained at 6 months following admission with the exception that the difference for highest ward status was not statistically significant. The findings of this small-scale study suggest that within the first 6 months of admission, it may be possible to distinguish patients who will probably make good progress in a MSU from those whose progress is likely to be very slow. Implications of the study are discussed.

Discourses of blame: accounting for aggression and violence on an acute mental health inpatient unit

The English National Service Framework for Mental Health stipulates that the highest quality of health care should be provided for mental health service users in the most efficient and effective manner. Incidents of aggression and violence militate against achieving that goal, yet such incidents are frequently reported in inpatient settings. Traditionally, research in this area has focused on the extent of the phenomenon, the individual characteristics of those involved and precursors to the incident. For the most part the literature reflects a dualistic, perpetrator/victim conceptualisation of incidents. This study aimed to address the lack of research undertaken from a more systemic perspective by examining how all those involved understood and attributed meaning to violent or aggressive situations and how these attributions justified individual perceptions, reactions and actions. Working from the position that all behaviour, including violent behaviour, has meaning to those involved and can be understood, 16 semi-structured interviews were carried out in one mental health unit. Because only one client was both willing and able to give a full account of an incident, we focus here on two incidents in which that client was involved. Discourse analytic techniques were used to examine her account of the two incidents and those of the staff members involved. Participants discussed key themes from the interviews in terms of several dilemmas: whether the violent or aggressive behaviour was 'mad' or 'bad'; predictable or unpredictable; and had resulted from 'personality' or ' mental illness'. The client and staff discourses were strikingly similar and in each case the central concern was with the attribution of blame. The findings have implications for the professional discourse of mental health care, including the discourse of the current policy agenda, a discourse itself constructed with the primary function of exoneration from and attribution of blame.
