Short-term risk assessment in the long term: A scoping review and meta-analysis of the Brøset Violence Checklist.

WHAT IS KNOWN ON THE SUBJECT?: The Brøset Violence Checklist (BVC) has been widely translated and implemented in diverse mental healthcare settings to improve prevention of violence. It is valued as a brief but effective tool in clinical practice. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: This review is the largest and most comprehensive international review of the BVC conducted in the 25+ years since the inception of the instrument in 1995. It integrates findings from existing studies and establishes that the tool has many impressive strengths considering the brief time investment required for completion. The review reveals that the tool has been used in more than 20 different countries around the world in a variety of mental health and other settings as both a risk assessment tool to guide clinical practice and as a formally structured intervention to minimize violence. There is much variation in how the tool is implemented and scored in different services. This variation questions its applicability as a resource and consistency and its use needs attention. This variation in use also limits the conclusions regarding best practices. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The review supports the use of the BVC as one part of the package for mental health services committed to preventive action aimed at reducing violence and coercion. The review identified that the patient perspective was often absent when completing the BVC, and so this should be considered as an option by services as part of a collaborative philosophy of care. ABSTRACT: INTRODUCTION: Existing literature on the Brøset Violence Checklist (BVC) is examined in the context of usability, implementation and validity to provide evidence-based recommendations on its application and identify opportunities for future development. AIM/QUESTION: To identify current knowledge on the BVC and guide clinicians and researchers toward the next steps in using this tool in clinical practice to prevent violence in healthcare settings. METHOD: A scoping review approach with a meta-analysis supplement was adopted to broadly identify and map available evidence on the BVC and provide specific estimates of predictive validity in different contexts. RESULTS: Sixty-two studies conducted in 23 countries addressed the implementation of the BVC across various settings. Many studies adapted the original BVC, and the clinical utility was noted as an important feature. A meta-analysis of the original BVC format estimated a pooled area under the curve at 0.83 (95% CI 0.78-0.87) in a subset of 15 studies. DISCUSSION: The BVC combines high predictive validity and good clinical utility across a wide range of settings and cultures. It should continue to be incorporated into routine practice in mental health services focused on preventing violence and coercion. IMPLICATIONS FOR PRACTICE: Development of collaborative approaches with service users involved in assessing their own risk of future violence.

Effect of an education program, risk assessment checklist and prevention protocol on violence against emergency department nurses: A single center before and after study.

AIM: The purpose of this study was to evaluate the effects of an education program, risk assessment checklist and preventive protocol on violence against emergency department nurses. METHODS: The design was a quasi-experimental before and after study of a group. A hospital emergency department's nurses participated in a workshop in which they were taught a method of using a risk assessment checklist and preventive protocol. The intervention lasted six weeks. The mean score and type of violence was measured before and after the intervention. The data were analyzed by SPSS. RESULTS: The mean score of violence before the intervention was 8.4 and after the intervention it was 2.7, which was statistically a significant difference (p < 0.0001). In addition, there were significant differences in the mean frequency of verbal abuse (p < 0.0001), assessment of workplace security (p = 0.006), fear of injury (p < 0.02) and type of reaction to violence (p < 0.01) before and after the intervention among the nurses. CONCLUSIONS: Using the BVC risk assessment checklist and preventive protocol can reduce the experience of violence and verbal abuse, which is the most common form of violence for emergency department nurses. Using this checklist and preventive protocol when patients arrive in emergency departments is recommended.

The Predictive Properties of Violence Risk Instruments May Increase by Adding Items Assessing Sleep.

Background: The psychometric instruments developed for short-term prediction of violence in psychiatric inpatients do not include variables assessing sleep. Disturbances in sleep may precede aggression in this setting. We investigated whether adding information on sleep improved the predictive properties of the Brøset Violence Checklist (BVC). Methods: The study population consists of all patients admitted to a psychiatric intensive care unit (PICU) over a 6-month period who were hospitalized for at least one night (n = 50). Sleep observed by staff (521 nights), behavior assessed with the BVC (433 days), and aggressive incidents recorded by the Staff Observation Scale-Revised (n = 14) were included in the analysis. Results: The ability of the BVC to predict aggressive incidents improved from AUCROC 0.757 to AUCROC 0.873 when a combined sleep variable including both sleep duration and night-to-night variations of sleep duration was added to the BVC recordings. The combined sleep variable did not significantly predict aggressive incidents (AUCROC 0.653, p = 0.051). Conclusions: A sleep disturbance variable improves the predictive properties of the BVC in PICUs. Further studies of sleep duration, night-to-night variations in duration of sleep, and aggression are needed.

Assessing the risk of violence in a psychiatric clinic: the Brøset Violence Checklist (BVC) Turkish version-validity and reliability study.

PURPOSE: This study was conducted for the purpose of adapting the Brøset Violence Checklist (BVC) for Turkish patients and testing its validity and reliability in measuring and predicting the risk of violence psychiatric in patients. DESIGN AND METHODS: The BVC and the Overt Aggression Scale (OAS) were used in the study. The BVC was distributed to 126 patients at the psychiatric clinic. The receiver operating characteristic (ROC), the Mann-Whitney U test and χ 2 analysis were carried out. FINDINGS: With a BVC total score cutoff of two points, 52% sensitivity and 100% specificity were found. A total of 47 violent episodes were observed in 25 patients. PRACTICE IMPLICATIONS: These results support the validity and reliability of the BVC. The Turkish version of the BVC was found to be a reliable and valid tool suitable for use in psychiatric inpatients.

Sleep at night and association to aggressive behaviour; Patients in a Psychiatric Intensive Care Unit.

Evaluations of associations between sleep at night and aggressive behaviour in Psychiatric Intensive Care Units (PICU) are lacking. The aims were to explore if sleep duration or night-to-night variations in sleep duration correlated with aggressive behaviour and aggressive incidents the next day and through the whole admission. Fifty consecutive patients admitted to a PICU were included (521 nights) and the nurses registered the time patients were sleeping, aggressive behaviour with The Brøset Violence Checklist (BVC) and aggressive incidents with The Staff Observation Aggression Scale-Revised (SOAS-R). At admission, short sleep duration the first night correlated with aggressive behaviour the next day and admissions with violent incidents had a median of 4.0 h difference in sleep from night one to night two compared to 2.1 h for the rest of the admissions. During the stay, large absolute difference in sleep duration between two nights correlated with aggressive behaviour the next day and short sleep duration was associated with violent incidents. Short sleep duration and night-to-night variations in sleep duration are both associated with increased risk for aggression in PICUs. This observation might help to predict and prevent aggressive incidents.

Aggression in Psychiatric Wards: Effect of the Use of a Structured Risk Assessment.

Health care workers are often exposed to violence and aggression in psychiatric settings. Short-term risk assessments, such as the Brøset Violence Checklist (BVC), are strong predictors of such aggression and may enable staff to take preventive measures against aggression. This study evaluated whether the routine use of the BVC could reduce the frequency of patient aggression. We conducted a study with a semi-random regression discontinuity design in 15 psychiatric wards. Baseline aggression risk was assessed using the Aggression Observation Short Form (AOS) over three months. The BVC was implemented in seven intervention wards, and the risk of aggressive incidents over three months of follow-up was compared with the risk in eight control wards. The analysis was conducted at the ward level because each ward was allocated to the intervention and control groups. At baseline, the risk of aggression varied between wards, from one aggressive incident per patient per 1,000 shifts to 147 aggressive incidents per patient per 1,000 shifts. The regression discontinuity analysis found a 45% reduction in the risk of aggression (Odds Ratio (OR) = 0.55, 95% confidence interval: 0.21-1.43). The study did not find a significant reduction in the risk of aggression after implementing a systematic short-term risk assessment with the BVC. Although our findings suggest that use of the BVC may reduce the risk of aggression, the results need to be confirmed in studies with more statistical power.

Comparing the effect of non-medical mechanical restraint preventive factors between psychiatric units in Denmark and Norway.

BACKGROUND: The use of mechanical restraint (MR) is controversial, and large differences regarding the use of MR are often found among countries. In an earlier study, we observed that MR was used twice as frequently in Denmark than Norway. AIMS: To examine how presumed MR preventive factors of non-medical origin may explain the differing number of MR episodes between Denmark and Norway. METHODS: This study is a cross-sectional survey of psychiatric units. Linear regression was used to assess the confounding effects of the MR preventive factors, i.e. whether a difference in the impact of these factors is evident between Denmark and Norway. RESULTS: Six MR preventive factors confounded [∆exp(B)> 10%] the difference in MR use between Denmark and Norway, including staff education (- 51%), substitute staff (- 17%), acceptable work environment (- 15%), separation of acutely disturbed patients (13%), patient-staff ratio (- 11%), and the identification of the patient's crisis triggers (- 10%). CONCLUSIONS: These six MR preventive factors might partially explain the difference in the frequency of MR episodes observed in the two countries, i.e. higher numbers in Denmark than Norway. One MR preventive factor was not supported by earlier research, the identification of the patient's crisis triggers; therefore, more research on the mechanisms involved is needed. CLINICAL IMPLICATIONS: None of the six MR preventive factors presents any adverse effects; therefore, units in Denmark and Norway may consider investigating the effect of implementing, the identification of the patient's crisis triggers, an increased number of staff per patient, increased staff education, a better work environment and reduced use of substitute staff in practice.

Mechanical restraint in psychiatry: preventive factors in theory and practice. A Danish-Norwegian association study.

PURPOSE: To examine how potential mechanical restraint preventive factors in hospitals are associated with the frequency of mechanical restraint episodes. DESIGN AND METHODS: This study employed a retrospective association design, and linear regression was used to assess the associations. FINDINGS: Three mechanical restraint preventive factors were significantly associated with low rates of mechanical restraint use: mandatory review (exp[B] = .36, p < .01), patient involvement (exp[B] = .42, p < .01), and no crowding (exp[B] = .54, p < .01). PRACTICE IMPLICATIONS: None of the three mechanical restraint preventive factors presented any adverse effects; therefore, units should seriously consider implementing these measures.

Health care help seeking behaviour among prisoners in Norway.

BACKGROUND: Prisoners are associated with high health care needs compared with the general population. This study aims to investigate prisoners' use of health service. METHODS: A cross-sectional study of 29 prisons in central and southern parts of Norway. A questionnaire was distributed to 1, 454 prisoners (90% response rate). Multilevel analyses were employed to analyse help seeking behaviour among the prisoners. RESULTS: Help seeking was substantially associated with sleep problems and drug problems. There was also a tendency for closed prisons as well as high staffing levels of healthcare professionals to be associated with elevated health care use. CONCLUSIONS: This study suggests that sleep problems and drug use are most frequently associated with health service use. The differences in health care use between prisons suggest that the implementation of prison health care standards should be addressed.

Using exercise to treat patients with severe mental illness: how and why?

In this study, one focus group and five individual semi-structured interviews were conducted to investigate nursing staff's ways of using exercise as part of the routine treatment for patients with severe mental illness (SMI). The study also explored the patients' experiences and views of the exercise program given in this secure hospital. The organization and delivery of the exercise program are also discussed. The findings indicate that successful outcomes and adherence to exercise programs for patients with SMI in a secure setting rely on therapeutic relationships, having exercise as a mandatory part of the treatment, positive reinforcement, and experienced instructors. More research is needed to identify effective exercise interventions and feasible delivery models for individuals with SMI in secure settings.

Can a focused staff training programme improve the ward atmosphere and patient satisfaction in a forensic psychiatric hospital? A pilot study.

OBJECTIVE: The main aim of the study was to describe whether staff training and lectures on milieu therapy to nursing staff can change the treatment environment, as perceived by the patients, in a desirable direction. The study was approved by the Regional Ethics Committee for Medical Research. METHOD: To measure the patients' perceptions of the treatment environment we used the Ward Atmosphere Scale (WAS). The ward atmosphere was evaluated three times during a 12-month period. Additionally, the patients completed five questions concerning satisfaction with the treatment environment. Between the first and the second ward evaluation the nursing staff was given 3 weeks of lectures on different aspects of milieu therapy. The nursing staff completed the WAS and three satisfaction items. RESULTS: The study revealed a change in desired direction after education in five of the six key subscales of the WAS (Involvement, Support, Practical orientation, Angry and aggressive behaviour and Order and organization). Staff control was the only subscale with no changes. The patients also reported an increase in satisfaction. The study revealed no major changes in the staff scores. The present study included only a small number of patients and examined the changes in only one psychiatric department; hence it could be argued that the results cannot be generalized to equivalent populations within the forensic services. CONCLUSIONS: The study indicated that it is possible to improve the ward atmosphere in a desirable direction by a 3-week training programme for nursing staff about important aspects of milieu therapy.

Assessing living skills in forensic mental health care with the behavioural status index: a European network study.

Assessment of living skills and violence risk in forensic psychiatric patients is a priority for clinicians. Suitably fine-grained instruments are rare. The goal of this study was to compare a norm-based psychometric assessment battery (the Behavioural Status [BEST] Index) with known valid instruments. Parallel cohort studies were undertaken in four European countries. Inpatients from 24 forensic psychiatric clinics were assessed three times using five instruments measuring living skills, psychological symptoms, aggression, and violence risk. Positive clinical changes were noted in insight, empathy, and some behaviors related to communication and living skills, with little change in violence risk, which was low to medium for most patients. Clinical congruence was observed between logically cognate items of the BEST Index and comparison instruments. Evidence for the scientific and clinical utility of the BEST Index as an effective tool for forensic psychiatric practice is discussed.

Assessing risk for imminent violence in the elderly: the Brøset Violence Checklist.

OBJECTIVE: The Brøset Violence Checklist (BVC) assesses confusion, irritability, boisterousness, verbal threats, physical threats and attacks on objects as either present or absent. It is hypothesised that an individual displaying two or more of these behaviours is more likely to be violent in the next twenty-four hour period. This study aims to test the validity of the instrument in geriatric settings and to report on the predictive value of an easy-to-use risk assessment instrument. METHOD: Eight thousand eight hundred and thirty-five BVC observations were completed in two psychogeriatric wards (n = 42 patients) and two special care units for patients with dementia (n = 40 residents). To measure violent incidents the study group was monitored using the Staff Observation Aggression Scale-Revised (SOAS-R). RESULTS: This study disclosed that patients in geriatric wards and residents in nursing homes who are aggressive have higher BVC scores than the non-violent subjects indicating that the BVC does predict violent episodes in these settings. CONCLUSION: From a clinical perspective, it is most important that a prediction aid has good sensitivity, so that most cases are detected and have a high negative predictive value so that most non-cases on the measure are indeed non-cases. Our results indicate that the BVC was able to achieve this goal.

Challenging behaviour in the elderly-monitoring violent incidents.

OBJECTIVE: To explore the frequency and nature of violent incidents in psychogeriatric wards and nursing homes in terms of type and severity of incidents, what provoked the incidents, and what kind of measure was needed to stop the aggression. MATERIAL AND METHODS: Aggressive behaviour of the study group was monitored using the Staff Observation Aggression Scale-Revised (SOAS-R( in two Norwegian nursing homes and two geriatric psychiatric wards for a period of three months. Severity of incidents were monitored with the built-in severity scoring system in SOAS-R. RESULTS: During the study period 32 out of the 82 patients were reported to be violent. The majority of the incidents were generated by a minority of the patients. Physical injury to the staff as a consequence of the aggression was extremely rare. Situations where the client was denied something were the most provocative ones and a substantial number of incidents occurred at bath/shower times. Talking to the patient was the most frequent measure used to stop the aggression, but more intrusive measures were also used. CONCLUSIONS: A substantial proportion of the incidents were associated with personal care tasks, suggesting a crucial role for communication difficulties and a focus for staff training. We suggest that personal care situations should be added to the variable list in future research.
