Reducing violence on a secure ward

Good practice issues in psychiatric intensive-care units

Aims and method

To survey some aspects of care relevant to good practice in psychiatric intensive-care units.

Results

A number of areas of concern were identified, including care issues for informal and female patients, a lack of uniform clinical leadership and a paucity of policies/guidelines for high-risk areas of clinical practice.

Clinical implications

In an attempt to provide a service for the most disturbed patients from widely varying sources, psychiatric intensive-care units are at risk of compromising the ability to provide good-quality clinical care.

Management of psychiatric in-patient violence in the Anglia region

Aims and method

A total of 384 incidents of violence against the person (six ‘serious' and 378 ‘mild’), by adult in-patients in general psychiatric units (GPUs) and learning disability units (LDUs) in 10 National Health Service trusts in the Anglia region, were evaluated by Interviews with staff and examination of records.

Results

The findings, when compared with standards derived from previous recommendations, showed deficiencies in the documentation of incidents (there was no satisfactory written record of physical restraint for 97% of incidents in GPUs and 86% in LDUs), in the training of staff in ‘control and restraint’ procedures (If two or more staff were involved In physical restraint, for 3% of incidents in GPUs and 100% in LDUs, the staff had received no training within the previous 12 months) and in policies for victim support (there was no written policy that included procedures for victim support in relation to 84% of incidents in GPUs and 44% in LDUs).

Clinical implications

Trusts should consider reviewing their policies on the prevention and management of violence, particularly in relation to staff training.

Safety and security procedures in psychiatric acute admission wards

Violence and assaultive behaviour is a serious and growing problem in psychiatric services across the world. Despite many concerns about violence and assault in healthcare, there is an alarming lack of clarity on matters of procedure and policy pertaining to safety and security in psychiatric hospitals.

This paper describes the safety and security measures in psychiatric acute admission wards in the Republic of Ireland and may be considered to be representative of acute psychiatric settings in other jurisdictions. A population study was undertaken, which included all psychiatric acute admission wards in the Republic. A descriptive survey research design was adopted, with the use of a questionnaire for data collection. The questionnaire was analysed using SPSS (version 11) and descriptive statistics were used to present the results.

There was wide variation in safety and security practices across the wards. Measures aimed at ensuring staff security were also lacking, with no overall acceptable minimal standards discernible. It may be concluded that there is a lack of coherent policy and procedure in safety and security measures across psychiatric acute admission wards. One has to ask to what extent the disparate practices in safety and security revealed in the results of the study account for the escalation in violent episodes and assaultive behaviour in psychiatric services in recent years.

Assaults on psychiatrists – a three year retrospective study

Objectives: This study investigates the problem of assaults on psychiatrists by their patients.

Method: A postal questionnaire was circulated to 178 psychiatrists and trainees working in the Dublin area enquiring about assaults experienced in the previous three years.

Results: Of those 147 (82%) who responded 57 (39%) had been assaulted. There were few discriminating factors between those assaulted and those not but those in child psychiatry were less likely and those in general adult psychiatry were more likely to have been the victim of an assault. Only 10% of respondents had received any formal training in violence management. Assailants tended to be male (63%) and known to the doctor involved (71%). Personality disorder (37%), schizophrenia (29%) and substance abuse (26%) were common assailant diagnoses. Management responses to the assaults were generally internal with administrative staff involvement in only four cases.

Conclusions: Factors which potentially protect or expose clinicians to a greater risk of assault are not well defined and need to be further explored. Simple clinician or patient variables are not especially predictive of violence risk. Clinicians need to acquaint themselves better with the basic practices of violence prevention and management. External measures (such as involving administration) could be used more frequently to combat this common problem.

Nurse staffing, RN mix, and assault rates on psychiatric units

The association between nurse staffing and patient violence on psychiatric units is unclear, and the association between nursing skill mix and violence has not been studied. Monthly data on physical/sexual assaults by patients against others were obtained for 351 adult psychiatric units. Total and injury assault rates were modeled as dependent variables using hierarchical Poisson regression, with total staffing and registered nurse (RN) mix as predictors. Assault rates were 12% higher per additional nursing hour per patient day but 6% lower per 5-point increase in percent of hours provided by RNs. In cubic spline models fit to explore nonlinear staffing-violence associations, assault rates increased with staffing through most of its range but began to decline at very high levels.

The antecedents of violence and aggression within psychiatric in-patient settings

OBJECTIVE

To systematically review the types and proportions of antecedents of violence and aggression within psychiatric in-patient settings.

METHOD

Empirical articles and reports with primary data pertaining to violence and aggression within adult psychiatric in-patient settings were retrieved. For each study, prospective antecedent data were extracted. The extracted antecedent data were thematically analysed, and all higher-level themes were meta-analysed using rate data.

RESULTS

Seventy-one studies met the inclusion criteria, from which 59 distinct antecedent themes were identified and organised into nine higher-level themes. The higher-level antecedent theme 'staff-patient interaction' was the most frequent type of antecedent overall, precipitating an estimated 39% of all violent/aggressive incidents. An examination of the staff-patient interaction themes revealed that limiting patients freedoms, by either placing some sort of restriction or denying a patient request, was the most frequent precursor of incidents, accounting for an estimated 25% of all antecedents. The higher-level themes 'patient behavioural cues' and 'no clear cause' also produced other large estimates and were attributed to 38% and 33% of incidents overall.

CONCLUSION

This review underscores the influence that staff have in making in-patient psychiatric wards safe and efficacious environments.

A narrative review of the effectiveness of aggression management training programs for psychiatric hospital staff

Workplace violence, including patient-perpetrated violence in healthcare settings, is increasingly being recognized as preventable. Staff training has been identified as a necessary component of any initiative aimed at preventing or reducing incidents of aggression and violence in the workplace. This narrative review of the literature evaluates the effectiveness of staff training programs designed to prevent and manage violence and aggression in psychiatric hospitals. An exhaustive review of the literature was performed on all articles published in English between January 1, 1990 and April 1, 2007 that evaluate an aggression management training program. Twenty-nine studies met the inclusion criteria for a full review and were summarized using a qualitative narrative approach. Aggression management training has been proven effective in some areas, such as reducing the use of restraints and other coercive control devices, but more methodologically rigorous research is needed to firmly establish whether it is effective in reducing aggression and staff injuries.

IMPLICATIONS

The findings of this study suggest that relying too heavily on aggression management staff training will have limited effect on addressing the range of issues related to patient-perpetrated violence in psychiatric hospitals. Mental healthcare organizations must look beyond staff training if they are to achieve meaningful reductions in aggressive incidents and staff injuries.

Manual restraint of adult psychiatric inpatients: a literature review

Relatively little is known about the prevalence of manual restraint to manage violent or challenging behaviour in hospital psychiatric services or the circumstances of its use. This review identified 45 empirical studies of manual restraint of adult psychiatric inpatients, mostly from the UK. On average, up to five episodes per month of manual restraint might be expected on an average 20-bed ward. Episodes last around 10 min, with about half involving the restraint of patients on the floor, usually in the prone position. Manually restrained patients tend to be younger, male and detained under mental health legislation. Staff value restraint-related training, but its impact on nursing practice has not been evaluated. Research has tended to focus on official reports of violent incidents rather than manual restraint per se. Larger and more complex studies are needed to examine how manual restraint is used in response to different types of incident and in different service settings.

Physical intervention: a review of the literature on its use, staff and patient views, and the impact of training

As a principal control measure, physical intervention is intended to be a skilled manual, or hands-on, method of physical restraint implemented by trained individuals, with the intention of controlling the aggressive patient, to restore safety in the clinical environment. Physical intervention is however a contentious practice. There have been reports in the literature of negative psychological views from staff and patients on the procedure. Although formal structured training was introduced in response to concerns around patient safety during restraint, concerns remain that PI is sometimes construed as a stand-alone violence prevention initiative. Its potential for misuse, and overuse, in corrupted cultures of care has emerged as a social policy issue. The following paper critically explores the literature on training in physical intervention in the United Kingdom.

On conflict, containment and the relationship between them

A programme of research into conflict (e.g. violence, absconding, medication refusal) and containment (e.g. seclusion, special observation, physical restraint) in inpatient psychiatry has been under way at City University, London, UK, for the past 10 years. Recent research findings, plus the challenges posed by ongoing projects, have made apparent the need for greater clarity about the overarching concepts of 'conflict' and 'containment'. This paper pulls together research findings pertaining to this issue, and conducts a reasoned analysis of what common characteristics might underlie 'conflict' and 'containment'. It is concluded that these are patient threats to safety, and the staff maintenance of safety. Details are presented on the inclusions and exclusions that follow from taking such a position, and potential definitions offered. On the grounds of this conceptual analysis, plus evidence for moderate degrees of statistical association between behaviours and events in each domain, it is concluded that it is legitimate to conduct analyses at the level of total conflict and containment rates, as well as at the level of individual types of behaviours and events (e.g. verbal abuse, sedation). Some of the mathematical difficulties in the analysis of total conflict and containment are addressed, and results of a weighting exercise presented. This exercise challenges our perception of the severity of some containment measures that are becoming more commonly used in acute psychiatry.

Views of nursing staff on the use of physical restraint

A postal questionnaire survey was employed in regional secure and psychiatric intensive care units in England and Wales, in respect of mental health nurses' training in the use of physical restraint. The nurses' views were sought relating to their last experience of implementing the procedure. Whilst most nurses (n = 259, 96.3%) reported positive outcomes in so far that the incident was brought under control, the views of the aftereffects of the procedure were of concern and ambivalence. The literature suggests that service users did not necessarily hold the same positive views. A range of alternatives, which were consistent with the literature, was made by staff to improve intervention in the management of violence. Negative aspects relating to the use of physical restraint were also highlighted. They included procedural, injury, clinical and management issues. Some respondents also expressed concerns about the negative attitudes of their colleagues. The findings of this aspect of the survey highlights that the therapeutic value of physical restraint can only be achieved with appropriate monitoring and with emphasis on psychological intervention in the prevention and management of violence.

Assessing the need for reactive behaviour management strategies in children with intellectual disability and severe challenging behaviour

The need for reactive behavioural management strategies for aggressive behaviours in adults with intellectual disability has been clearly established, but equivalent information concerning children with challenging behaviour is lacking by comparison. The present study was conducted in order to assess this need. A retrospective study was conducted to ascertain the nature of aggressive behaviours amongst a cohort children referred to a specialist support service. Aggressive behaviours were found to occur at high rates within the study group. Almost 60% of the children displayed aggression that occurred at least daily, and the behaviours resulted in serious consequences for carers in almost one-third of the group. Physical interventions were already in use in 56% of cases, but were largely improvised by carers. The need to include reactive behavioural training as part of an overall intervention package for carers of children with challenging behaviour appeared to be supported by the present results. The implications for training design are discussed.

A cost analysis of untoward incidents in a medium secure unit

All untoward incidents perpetrated by 36 patients--residents in a medium-secure hospital--over a period of six months were examined using a prospective design. Demographic and psychiatric details of patients involved in incidents were compared with those of patients not involved in incidents. Financial costs associated with incidents were calculated. A minority of patients were found to be responsible for the majority of incidents. Patients detained under criminal sections of the Mental Health Act 1983 were involved in disproportionately more incidents than their civil section counterparts. The female patients involved in untoward incidents all had a diagnosis of personality disorder and were over-represented in the number of incidents. However, most of the financial burden of untoward incidents was incurred by those incidents perpetrated by male patients. Likewise, although patients detained under the legal category of psychopathic disorder were involved in a higher number of incidents, higher costs were associated with incidents perpetrated by patients detained under the category of mental illness.

Aggressive behaviour in the elderly

In this paper, the literature on aggressive behaviour in the elderly is reviewed, with emphasis on: definition; study samples; patient groups; study designs and methodology; data collection; instruments used to measure aggressive behaviour; social, clinical, demographic and biological correlates; prevalence and rates; precipitants; outcome; site; timing; daily and seasonal variation; patterns of usage of hospitals and other institutions; stuffing levels, staff morale, staff attitudes, staff training and other staffing factors.

Acute disturbed or violent behaviour: principles of treatment

Acute disturbed or violent behaviour has a number of organic, iatrogenic and psychological precipitants and is commonly encountered. Various models have been used to define such behaviour and to suggest non-pharmacological treatments. However, drugs are frequently used and a wide variety of regimens are employed. Robust research into the use of drugs in acute, disturbed behaviour is scant. Nevertheless a treatment protocol is presented based on primary research, review articles and clinical experience.
