Causes and management of patient aggression and violence: staff and patient perspectives

Aim.  This paper reports a study of staff and patient perspectives on the causes of patient aggression and the way it is managed.
Background.  The incidence of aggression in healthcare is reportedly on the increase, and concerns about the management of this problem are growing.
Method.  A convenience sample of 80 patients and 82 nurses from three inpatient mental healthcare wards were surveyed using The Management of Aggression and Violence Attitude Scale. A further five patients and five nurses from the same sample participated in a number of follow-up interviews.
Results.  Patients perceived environmental conditions and poor communication to be a significant precursor of aggressive behaviour. Nurses, in comparison, viewed the patients' mental illnesses to be the main reason for aggression, although the negative impact of the inpatient environment was recognized. From interview responses, it was evident that both sets of respondents were dissatisfied with a restrictive and under-resourced provision that leads to interpersonal tensions.
Conclusion.  There are differences between the views of staff and patients about reasons for aggression and its management. Future approaches therefore need to be developed that address these opposing views. For example, training in the use of fundamental therapeutic communication skills was advocated by patients, whilst the need for greater attention to organizational deficits was advocated by nurses. A move away from reliance on the use of medication was also felt to be necessary. Evaluation of local needs and practices must be an integral part of this process.     

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.     

An evaluation of staff training in psychological techniques for the management of patient aggression

• ? Training for staff working with violent patients is frequently recommended, sometimes implemented, but rarely objectively evaluated.
• ? In this longitudinal study 47 nurses attending a training day to learn strategies for coping with violent psychiatric patients were compared with 108 non-attending control group subjects.
• ? The rate of assaults on staff on wards taking part in the study was 31% lower after implementation of the training and wards sending a majority of staff to the training experienced a particularly significant reduction in assaults.
• ? The effectiveness of this 1-day training package is discussed.

     

Piloting violence and incident reporting measures on one acute mental health inpatient unit

During May, 2006, on one acute mental health inpatient unit, nursing staff evaluated each patient three times a day (i.e., once each nursing shift) using the Broset Violence Checklist (BVC). Associated data were collected using the Staff Observation and Aggression Scale-Revised (SOAS-R) if an adverse incident occurred. At the end of the data collection period, the nursing staff were asked to complete a short questionnaire anonymously to evaluate how useful they had found the instruments. N = 93 patients were admitted to the unit during the month of study. Seven incidents were reported using the SOAS-R. A slight trend was noted for higher BVC score in aggressive patients. A potential high occurrence of underreporting on incidents was observed. There was limited feedback data from nursing staff at the end of the study, but the responses received were encouraging for continued use of the instruments in practice. The pilot study fulfilled its purpose in two ways. First, it allowed staff on the unit to experience using structured instruments to support their practice. Second, it allowed an opportunity to raise awareness of potential underreporting and tolerance of aggression on the unit.     

An evaluation of an aggression management training program to cope with workplace violence in the healthcare sector

Workplace violence is a major occupational hazard for healthcare workers, generating a need for effective intervention programs. The purpose of this study was to evaluate the effectiveness of an aggression management training program. The evaluation design was based on the internal referencing strategy, an unobtrusive and applicable evaluation method that rules out some major threats to internal validity without the need for a control group. On three occasions, training participants completed a questionnaire containing experimental and control variables. As hypothesized, there was a significant improvement in the experimental variables that was larger than the non-significant change in the control variable. We conclude that aggression management training may be an effective instrument in the fight against workplace violence.     

The effect of a training course on mental health nurses' attitudes on the reasons of patient aggression and its management

Aggression in healthcare systems poses a major problem for nurses because they are the most susceptible to suffer violence. Studies demonstrate that attitudes of nurses influence their behaviour regarding aggression and violence. Training programmes can positively change nurses' attitudes. This quasi-experimental study aimed to examine the effects of a systematic training course in aggression management on mental health nurses' attitudes about the reasons for patients' aggression and on its management. Sixty-three nurses (29 in the intervention and 34 in the control group) participated in this quasi-experimental pre-test and post-test study. The attitude of the participants of a training course was recorded by the German version of the Management of Aggression and Violence Attitude Scale (MAVAS). No significant attitude changes occurred in the intervention group at post-test. It is concluded that trainings intending to influence attitudes regarding the reason for patient aggression should consider the impact of the pedagogical quality of the training course, organizational support, and the user's perception. Moreover, it remains questionable to what extent a single instrument of measurement can record attitude changes.     

Patient aggression in clinical psychiatry: perceptions of mental health nurses

Mental health nurses are faced with an increasing number of aggressive incidents during their daily practice. The coercive intervention of seclusion is often used to manage patient aggression in the Netherlands. However, GGZ Nederland, the Dutch association of service providers for mental health and addition care, has initiated a project to decrease the number of seclusions in clinical psychiatry. A first step in this project is to gain insight into the current situation: the perceived prevalence of patient aggression, the attitudes of mental health nurses towards patient aggression and those socio-demographic and psychosocial factors that contribute to the use of coercive interventions. A survey was undertaken among 113 nurses from six closed and semi-closed wards. In this survey, two questionnaires were used: (1) the Attitude Toward Aggression Scale; and (2) the Perceptions of the Prevalence of Aggression Scale. Variables derived from the Theory of Planned Behaviour were also measured. Nurses reported being regularly confronted with aggression in general and mostly with non-threatening verbal aggression. They perceived patient aggression as being destructive or offensive and not serving a protective or communicative function. The nurses generally perceived themselves as having control over patient behaviour (i.e. considerable self-efficacy) and reported considerable social support from colleagues. Although the nurses in this study were frequently confronted with aggression, they did not experience the aggression as a major problem.     

Modifiable factors affecting inpatient violence in an acute child and adolescent psychiatric unit: A 16‐year retrospective study

Violent incidents in acute inpatient units for children and adolescents are a major and persistent problem. The demographic, clinical, and modifiable (environmental–organizational) risk factors that affect inpatient violence in an Acute Child and Adolescent Psychiatric Unit were investigated via a retrospective study. Data were collected from nursing and medical reports and the unit's census and included 100 days per year for 16 years. Incidents of violence and assault types were recorded, and variables such as the diagnostic category of assailants, total number of patients, and staffing factors during the incident were examined. Of the 2390 violent incidents recorded, 50% were attributed to cases of physical violence towards another patient, 17% to physical violence towards nursing staff, 19% to physical violence towards self and 14% to destruction of property. According to the final multivariable model, for each additional patient in the unit, the risk of a violent event increased by 9.51%; for each additional offender patient, the risk increased by 14.06%; the number of assistant nurses was associated with a 25.03% increased risk; and, after 2006, the risk increased by 68.99%. The most significant factor associated with a 59.98% decreased risk was the total number of nursing staff. All variables significantly and independently contributed to the model. Acute inpatient psychiatric units with a small number of hospitalized patients, adequate, well‐trained and specialized nursing staff, and the hospitalization of different types of patients in separate wards or units are expected to facilitate a reduction in the frequency of violent incidents.     

The effect of a training course in aggression management on mental health nurses' perceptions of aggression: a cluster randomised controlled trial

Nurses' attitudes towards patient aggression may influence their behaviour towards patients. Thus, their enhanced capacity to cope with aggressive patients may nurture more positive attitudes and alleviate adverse feelings emanating from patient aggression. This cluster randomised controlled trial conducted on six psychiatric wards tested the hypotheses that a 5 day training course in aggression management would positively influence the following outcome measures: Nurses' perception and tolerance towards patient aggression and resultant adverse feelings. A repeated measures design was employed to monitor change. No effect was found. The short time frame between the training course and the follow up measurement or non-responsiveness of the measurement instruments may explain this finding.     

Specialist educational intervention for acute inpatient mental health nursing staff: service user views and effects on nursing quality

AIM: This paper reports a study to evaluate the impact of an innovative 18-day educational intervention for acute ward-based mental healthcare nursing staff on documented quality of nursing care and on service user views of that care. BACKGROUND: There are grave concerns internationally about the quality of inpatient mental health care for people with acute psychiatric problems. It is claimed that specialist educational courses are needed to improve these services. However, whilst such courses may lead to positive learning outcomes for participants, the impact on the actual care of service users is unknown. METHOD: An uncontrolled before-and-after evaluation of three acute mental health wards from different United Kingdom National Health Service trusts was carried out. Quality of nursing care was evaluated by extracting documentary evidence from service user records, assessed by two independent researchers according to predefined quality criteria. The views of a purposive sample of mental health service users, currently receiving services from the three designated wards, were ascertained by semi-structured interview. RESULTS: Both documentary evidence and service user views revealed some important baseline deficiencies in the quality of care offered at the study sites. Following the educational intervention, statistically significant improvements were observed in the quality of care planning, initial assessments and the provision of therapeutic care. No statistically significant changes were observed in the quality of risk assessments, medication management or external agency involvement. CONCLUSIONS: Education can have an impact on nursing care but may not be sufficient alone to change mental healthcare practices on acute inpatient wards in the radical manner demanded by policymakers and service user lobby groups. Educational interventions need to be implemented in conjunction with organizational changes that are specifically designed to maximize the opportunities presented by a newly skilled and positive workforce.     

An exploratory account of registered nurses' experience of patient aggression in both mental health and general nursing settings

Until relatively recently, aggression and violence in nursing has been an area of little discussion (Poster & Ryan 1993). Today, concerns are rising about escalating levels of violence towards nurses (Wykes 1994, Whittington 1997). In response, this paper explores registered nurses' experiences of patient aggression encountered in the acute inpatient general and mental health settings. Critical incidents from registered nurses in both areas are examined and analyzed in relation to existing literature. The aim of the research is to ascertain if differences exist or similarities prevail. Findings reveal that the two areas have similar problems in terms of types of aggression. Verbal and 'minor' types of aggression are the most problematic. Also, the 'biomedical model' of care is evident in both settings and possibly underpins chosen approaches to aggression management. The repeated use of chemical and physical restraint is apparent. The main comparison identified between the two groups relates to nursing control over situations involving violent patients. Mental health nurses seem to consistently take control of aggressive situations whilst general nurses tend to rely more heavily upon the input of others (medical staff, mental health teams and the police) when intervening. These two nursing specialties therefore have much to learn from each other in terms of nursing experience and possible future approaches to the management of aggressive patients.     

The effectiveness of two interventions in the management of patient violence in acute mental inpatient settings: report on a pilot study

Systematic risk assessment and training courses have been suggested as interventions to deal with patient violence in psychiatric institutions. A dual centre prospective feasibility study was conducted on two Swiss psychiatric admission wards to test the hypothesis that such interventions will reduce the frequency and severity of violent events and coercion. A systematic aggression risk assessment, in combination with a standardized training course in aggression management was administered and the frequency and severity of aggressive incidents and the frequency of coercive measures were registered. The incidence rates of aggressive incidents and attacks showed no significant reduction from the baseline through risk prediction and staff training, but the drop in coercive measures was highly significant. A 'ward effect' was detected with one ward showing a decline in attacks with unchanged incidence rates of coercion and the other ward showing the opposite. The severity of the incidents remained unchanged whilst the subjective severity declined after the training course. We conclude that a systematic risk assessment and a training course may assist in reducing the incidence rate of coercive measures on psychiatric acute admission wards. Further testing of the interventions is necessary to measure the effect of the training alone and to counteract 'ward effects'.     

De‐escalation: A survey of clinical staff in a secure mental health inpatient service

De‐escalation is an important tool for preventing aggression in inpatient settings but definitions vary and there is no clear practice guideline. We aimed to identify how clinical staff define and conceptualize de‐escalation, which de‐escalation interventions they would use in aggressive scenarios, and their beliefs about the efficacy of de‐escalation interventions. A questionnaire survey (n = 72) was conducted using open and closed questions; additionally, clinical vignettes describing conflict events were presented for participants to describe their likely clinical response. Qualitative data were subject to thematic analysis. The major themes that de‐escalation encompassed were communication, tactics, de‐escalator qualities, assessment and risk, getting help, and containment measures. Different types of aggression were met with different interventions. Half of participants erroneously identified p.r.n. medication as a de‐escalation intervention, and 15% wrongly stated that seclusion, restraint, and emergency i.m. medication could be de‐escalation interventions. Those interventions seen as most effective were the most commonly used. Clinical staff's views about de‐escalation, and their de‐escalation practice, may differ from optimal practice. Use of containment measures and p.r.n. medication where de‐escalation is more appropriate could have a negative impact; work is needed to promote understanding and use of appropriate de‐escalation interventions based on a clear guideline.     

The physical and mental health of acute psychiatric ward staff,and its relationship to experience of physical violence

To evaluate and describe the physical and mental health of staff on acute psychiatric wards and examine whether violence exposure is linked with health status. We undertook a cross‐sectional survey with 564 nursing staff and healthcare assistants from 31 psychiatric wards in nine NHS Trusts using the SF‐36, a reliable and valid measure of health status and compared summary scores with national normative data. Additional violence exposure data were collated simultaneously and also compared with health status. The physical health of staff was worse, and their mental health was better than the general population. Physical health data were skewed and showed a small number of staff in relatively poor health while the majority were above average. Better physical health was associated with less time in the current post, a higher pay grade, and less exposure to mild physical violence in the past year. Better mental health was associated with being older and from an ethnic minority background. Violence exposure influenced physical health but not mental health when possible confounders were considered. Mental health was strongly influenced by ethnicity, and further research might highlight the impact on own‐group ethnic density on the quality of care. The impact of staff whom are physically unwell or impaired in the workplace needs to be considered as the quality of care may be compromised despite this being an example of inclusiveness, equal opportunities employment, and positive staff motivation.     

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.     

Prevalence and predictors of verbal aggression in a secure mental health service: Use of the HCR‐20

Despite evidence about the negative effects of verbal aggression in mental health wards there is little research about its prevalence or about the factors that predict the behaviour among inpatients. This study aimed to determine the prevalence of verbal aggression in a secure mental health service, and to examine the relationship of verbal aggression with risk factors for aggression in the risk assessment tool HCR‐20 in order to establish whether, and with which factors, the behaviour can be predicted. Verbal aggression was measured using the Overt Aggression Scale (OAS) over a 3‐month period across a heterogeneous patient group (n = 613). Over half the patients (n = 341, 56%) engaged in 1594 incidents of verbal aggression. The HCR‐20 total, clinical, and risk management subscale scores predicted verbal aggression, though effect sizes were not large. Item‐outcome analysis revealed that impulsivity, negative attitudes, and non‐compliance with medication were the best predictors of verbal aggression and, therefore, should be targeted for intervention. There are key synergies between factors predicting verbal aggression and the core mental health nursing role. Nurses, therefore, are in a prime position to develop and implement interventions that may reduce verbal aggression in mental health inpatients.     

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.
