Overcrowding in psychiatric wards and physical assaults on staff: data-linked longitudinal study

Exploring patient safety risk in an emergency ward for substance use through a mixed-method analysis

BACKGROUND

There is limited knowledge of how psychiatric patient safety measures can detect and understand risk as an emergent property within a healthcare system. Overcrowding poses a risk for patient safety in psychiatric emergency wards and is associated with increased mortality and violence. This paper aims to explore patterns of risk emergence in a psychiatric ward and provide insights into the dynamics of workload pressure.

METHOD

A case study was conducted in a psychiatric emergency ward for patients with substance use disorders. The study employed a four-phased mixed-methods design. Phase one used clinical experts to identify patient safety pressure issues. Phase two used data on patient visits extracted from medical records between 2010 and 2020. In phase three, a quantitative analysis of patient visits and diagnosis was made. Phase four used a focus group of clinical experts for a semi-structured interview, analysing the result from phase three.

RESULT

Trend analysis demonstrated a steady growth of patient visits to the emergency ward over the studied ten-year period. The findings showed a decrease in patients being diagnosed with delirium when visiting the emergency ward and an increase in percentage of patients receiving a psychosis diagnosis. The focus group expressed concerns about delayed treatments, increased violence and underestimating patients' needs.

CONCLUSION

This study indicated that increased workload pressure can be predicted at a system level by analysing patient visits and diagnostics trends over time. The study advocates for ongoing awareness of patient safety risks by monitoring factors identified by clinical front-end workers as potential sources of risk. Healthcare management could employ supportive tools to detect and address emerging risks, including expected workload, overcrowding, staffing issues or bed shortages.

Developing nurse-sensitive outcomes in acute inpatient mental health settings-A systematic review

BACKGROUND

While nurse-sensitive outcomes (NSOs) are well established in numerous health settings, to date there is no indicator suite of NSOs for inpatient mental health settings.

AIM

To assess the relationship between nursing variables and patient outcomes in acute inpatient mental health settings to determine which outcomes can be used as indicators of the quality of nursing care.

METHODS

Databases accessed were CINAHL, MEDLINE, PsycINFO and EMBASE, last searched in May 2022. The review followed the 2020 PRISMA checklist for systematic reviews. Papers published between 1995 and 2022, conducted in acute mental health care units were included. The quality of the studies was assessed using the Effective Public Health Practice Project Quality Assessment Tool. A meta-analysis was not possible because of the large number of variables and measurement inconsistencies.

RESULTS

A total of 57 studies were reviewed. Studies were categorised according to whether they found a significant or non-significant relationship between nurse variables and patient outcomes. Seven outcomes-aggression, seclusion, restraint, absconding, pro-re-nata medications, special observations and self-harm-were identified. For each outcome, there were significant findings for several nurse variables indicating that all included outcomes could be used as NSOs. However, evidence for aggression, seclusion and restraint use as suitable NSOs was more robust than the evidence for self-harm, absconding, pro-re-nata medications and special observations.

CONCLUSION

All the seven outcomes can all be used to develop an NSO indicator suite in mental health inpatient settings. More work is needed to establish high-quality studies to clearly demonstrate the relationship between these outcome measures and changes in nurse variables such as nurse staffing, skill mix, work environment, nurse education and nurse experience.

PATIENT AND PUBLIC CONTRIBUTION

Patient or public contribution was not possible because of the type of the variables being explored.

An analysis of Chinese nursing electronic medical records to predict violence in psychiatric inpatients using text mining and machine learning techniques

BACKGROUND

The prevalence of violence in acute psychiatric wards is a critical concern. According to a meta-analysis investigating violence in psychiatric inpatient units, researchers estimated that approximately 17% of inpatients commit one or more acts of violence during their stay. Inpatient violence negatively affects health-care providers and patients and may contribute to high staff turnover. Therefore, predicting which psychiatric inpatients will commit violence is of considerable clinical significance.

OBJECTIVE

The present study aimed to estimate the violence rate for psychiatric inpatients and establish a predictive model for violence in psychiatric inpatients.

METHODS

We collected the structured and unstructured data from Chinese nursing electronic medical records (EMRs) for the violence prediction. The data was obtained from the psychiatry department of a regional hospital in southern Taiwan, covering the period between January 2008 and December 2018. Several text mining and machine learning techniques were employed to analyze the data.

RESULTS

The results demonstrated that the rate of violence in psychiatric inpatients is 19.7%. The patients with violence in psychiatric wards were generally younger, had a more violent history, and were more likely to be unmarried. Furthermore, our study supported the feasibility of predicting aggressive incidents in psychiatric wards by using nursing EMRs and the proposed method can be incorporated into routine clinical practice to enable early prediction of inpatient violence.

CONCLUSIONS

Our findings may provide clinicians with a new basis for judgment of the risk of violence in psychiatric wards.

Associations between violence, self-harm and acute psychiatric service use: Implications for inpatient care

WHAT IS KNOWN ON THE SUBJECT?: Service users who behave violently may suffer. This is because violence can lead to unnecessary medication, seclusion on the ward and strained relationships with other people. It can also affect a service user's self-esteem and lead to feelings of shame. Service users who behave violently can also make life frightening and unpredictable for members of staff, and other service users on the ward. It is important to gain a sound understanding of violence in order to help reduce it. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Previous research has shown that having a past history of violence, being admitted to PICU and being admitted to hospital under section is associated with violent behaviour on the ward. We identified several new factors associated with violent behaviour, such as engaging in self-harm, being the target of another person's violence and being referred to a Psychiatric Liaison Team.

IMPLICATIONS FOR PRACTICE

For some service users, behaving violently may be a response to previous trauma and an expression of distress. It is therefore important that mental health nurses are supported by their employers to work with service users in a trauma-informed manner. Nurses employed across a range of psychiatric settings could benefit from direct interventions such as comprehensive trauma-informed care training and psychological debrief spaces, or systemic interventions to address staff shortages and improve ward conditions.

ABSTRACT

INTRODUCTION: Instances of violence in acute psychiatric settings are frequent, can be devastating for service users and staff, and are costly. Such settings would benefit from a greater understanding of violence.

AIM

We analysed the association between current and historical variables and rates of inpatient violence. To address gaps in current research, we included instances of self-harm and being the target of violence. We also included seldom used service metrics.

METHOD

Data were extracted on admissions to acute adult wards and PICUs 2017-2020 within South London and Maudsley NHS Foundation Trust. A zero-inflated negative binomial regression mixed model was used to analyse the impact of variables on rates of violence.

RESULTS

Variables associated with an increased rate of violence were as follows: an increased number of violent incidents in the year before admission, being admitted on MHA section, being admitted to PICU, instances of self-harm, being the target of violence and referral to a Psychiatric Liaison Team.

DISCUSSION

The novel associations found between enacting violence, self-harm and being the target of violence indicate trauma-informed care is crucial to reduce violent presentations of distress.

IMPLICATIONS FOR PRACTICE

System level interventions are crucial to ensure mental health nurses are supported to provide trauma-informed care.

Consistency of Violence: Implications for Effective Inpatient Psychiatric Care

Instances of violence and aggression in acute psychiatric settings are common and highly distressing for service users and staff. They also incur financial costs. This study aimed to identify the proportion of service users at risk of consistent violence/aggression enactment. It also aimed to analyse associated service use to explore the potential need for specialised, targeted approaches. Five years' worth of data were extracted from 2016 to 2020 on inpatient stays across South London and Maudsley NHS Foundation Trust (SLaM) acute adult wards and Psychiatric Intensive Care Units (PICUs). Service users were divided into cohorts based on relative number of violent/agressive incidents enacted. Differences in frequency of acute service use during the period 1st January-31st December 2020 were analysed. In total, 2524 service users had at least one inpatient stay during 2020. 679 were recorded as having enacted at least one incident of violence or aggression. Just 4% of all service users accounted for 50% of all violence/aggression enactment. Results further showed strong evidence of group differences between violence cohorts in the following domains: internal transfers, occupied bed days, admissions and Place of Safety (PoS) referrals. There was weaker evidence for group differences in referrals to Home Treatment teams (HTTs) and Psychiatric Liaison Teams. A small proportion of service users disproportionately account for the majority of violent and aggressive incidents and higher levels of violence and aggression are associated with more acute service use. The provision of targeted, personalised interventions for this cohort may reduce the enactment of violence and aggression, leading to improved quality life and a reduction in financial expenditure.

Space and Well-Being in High Security Environments

Research into the spatial dimensions of deprivation of liberty and psychiatric hospitalization has a long and complex tradition. In this context, the increasing numbers of prisoners and patients in forensic hospitals have impressively shown how difficult it is to ensure security, therapy and rehabilitation when space is scarce or not well-suited. In this narrative review, we present the main findings of recent lines of research on spaces in prisons and forensic psychiatric wards, with particular attention to the links between overcrowding in prisons and secure forensic psychiatric hospitals and violence, the foundations of prison and hospital architecture, and on how the design of spaces in prisons and hospitals can influence well-being. We assess and discuss these findings in the context of the current debate on how well-being in secure spaces can support the achievement of rehabilitation goals even in overcrowded institutions.

Multi-center nationwide study on pediatric psychiatric inpatients 2000-2018: length of stay, recurrent hospitalization, functioning level, suicidality, violence and diagnostic profiles

Inpatient treatment is an important part of child and adolescent psychiatric (CAP) care. This nationwide study explores the changes in length of stay, recurrent hospitalization, functioning level, suicidality, violence and diagnoses of CAP inpatients in Finland in 2000, 2011 and 2018. We obtained comprehensive questionnaire data on each study year from 93 to 95% of all CAP wards in Finland. We split the 1276 inpatients into two age groups in each study year: under 13 and 13-18. The median length of stay in inpatient treatment decreased from 82.0 days in 2000 to 20.5 days in 2018 (p < 0.001) and recurrent hospitalization increased from 38 to 46%. General functioning, which was evaluated by the Children's Global Assessment Scale, deteriorated by an average of six points between 2000 and 2018. Violent threats decreased from 21.5 to 16.6% and violent acts decreased from 26.9 to 20.3%. Suicidal threats decreased from 42.6 to 23.3% in those aged under 13 and remained stable among those aged 13-18. In the 13-18 group, there was an increase in the diagnoses of ADHD, from 5.0 to 16.9% and depression, from 25.1 to 41.7%. However, psychosis decreased from 23.2 to 12.6% in the older age group. In the whole cohort, anxiety disorders increased from 7.6 to 15.6%. The overall picture does not show that CAP inpatients have become more disturbed. While the general functioning of CAP inpatients deteriorated somewhat over the 2000-2018 study period, symptoms of suicidality and violence remained stable or decreased. There was also a continuous increase in short-term treatment.

Aggression on the psychiatric ward: Prevalence and risk factors. A systematic review of the literature

INTRODUCTION

On psychiatric wards, aggressive behaviour displayed by patients is common and problematic. Understanding factors associated with the development of aggression offers possibilities for prevention and targeted interventions. This review discusses factors that contribute to the development of aggression on psychiatric wards.

METHOD

In Pubmed and Embase, a search was performed aimed at: prevalence data, ward characteristics, patient and staff factors that are associated with aggressive behaviour and from this search 146 studies were included.

RESULTS

The prevalence of aggressive behaviour on psychiatric wards varied (8-76%). Explanatory factors of aggressive behaviour were subdivided into patient, staff and ward factors. Patient risk factors were diagnosis of psychotic disorder or bipolar disorder, substance abuse, a history of aggression, younger age. Staff risk factors included male gender, unqualified or temporary staff, job strain, dissatisfaction with the job or management, burn-out and quality of the interaction between patients and staff. Staff protective factors were a good functioning team, good leadership and being involved in treatment decisions. Significant ward risk factors were a higher bed occupancy, busy places on the ward, walking rounds, an unsafe environment, a restrictive environment, lack of structure in the day, smoking and lack of privacy.

CONCLUSION

Despite a lack of prospective quantitative data, results did show that aggression arises from a combination of patient factors, staff factors and ward factors. Patient factors were studied most often, however, besides treatment, offering the least possibilities in prevention of aggression development. Future studies should focus more on the earlier stages of aggression such as agitation and on factors that are better suited for preventing aggression such as ward and staff factors. Management and clinicians could adapt staffing and ward in line with these results.

The violence prevention climate of mental health wards: a cross-sectional study of staff and patient views

PURPOSE

Ward climate can shape the behaviour of both staff and patients. A subset of the ward climate is the violence prevention climate, the unique characteristics that are perceived by the people within the environment as contributing towards the prevention of violence. The aim of this study was to explore differences between and within staff and patient groups in terms of their perceptions of the violence prevention climate.

METHODS

A cross-sectional survey was conducted with staff (n = 326) and patients (n = 95) in mental health care pathways within one charitable trust. All participants completed the VPC-14 to measure perceptions of the violence prevention climate, a validated 14-item two-factor scale (staff actions and patient actions). Staff demographic information was collected on the VPC-14 front sheet; patient demographic, clinical and violence data were collected from electronic case records. Bivariate analyses were conducted to compare within- and between-group variables. Significant staff and patient variables were entered into multiple hierarchical regression analyses to assess their relationship with VPC-14 factors.

RESULTS

Staff had a more positive view than patients of staff actions and patients had a more positive view of patient actions than did staff; staff- or patient-group membership was the best predictor of staff action scores. Individual staff characteristics accounted for a small amount of the variance in staff and patient action scores; individual patient characteristics explained more variance, but this was still below 20%.

CONCLUSIONS

Staff perceive their violence prevention-related contributions more positively than patients and vice versa. This has implications for staff; they may need to better articulate their role in violence prevention to patients, as well as recognise the role that patients play. However, within staff and patient groups, individual variables only make up a small amount of variance of perceptions of the violence prevention climate. This suggests that the violence prevention climate is a valid construct, i.e. that despite differences in individual variables, individuals within the patient group have similar perceptions of the VPC, as do those within the staff group.

An investigation of clinical decisionmaking: identifying important factors in treatment planning for suicidal patients in the emergency department

OBJECTIVE

We sought to evaluate the influence of several well-documented, readily available risk factors that may influence a psychiatric consultant's decision to admit an emergency department (ED) patient reporting suicidal ideation for psychiatric hospitalization.

METHODS

We conducted a retrospective study of adult patients presenting to six affiliated EDs within Pennsylvania from January 2015 to June 2017. We identified 533 patients reporting current active suicidal ideation and receiving a complete psychiatric consultation. Socio-demographic characteristics, psychiatric presentation and history, and disposition were collected. Decision tree analysis was conducted with disposition as the outcome.

RESULTS

Four of 27 variables emerged as most influential to decisionmaking, including psychiatric consultant determination of current suicide risk, patient age, current depressive disorder diagnosis, and patient history of physical violence. Likelihood of admission versus discharge ranged from 97% to 58%, depending on the variables considered. Post hoc analysis indicated that current suicide plan, access to means, lack of social support, and suicide attempt history were significantly associated with psychiatric consultant determination of moderate-to-high suicide risk, with small-to-medium effect sizes emerging.

CONCLUSIONS

Only a handful of variables drive disposition decisions for ED patients reporting current active suicidal ideation, with both high and low fidelity decisions made. Patient suicide risk, determined by considering empirically supported risk factors for suicide attempt and death, contributes the greatest influence on a psychiatric consultant's decision to admit. In line with American College of Emergency Physicians (ACEP) recommendations, this study accentuates the importance of using clinical judgment and adjunct measures to determine patient disposition within this population.

Observed Outcomes: An Approach to Calculate the Optimum Number of Psychiatric Beds

The number of psychiatric beds, in most developed countries, has decreased progressively since the late 1950s. Many clinicians believe that this reduction has gone too far. But how can we determine the number of psychiatric beds a mental health system needs? While the population health approach has advantages over the normative approach, it makes assumptions about optimal and minimum duration of hospitalization required for various psychiatric disorders. In this paper, we describe a naturalistic approach that estimates the required number of psychiatric beds by comparing the bed levels at which negative outcomes develop in different jurisdictions. We hypothesize that there will be a threshold below which negative outcomes will be seen across jurisdictions. We predict that hospital key performance indices will be more sensitive to bed reductions than the clinical and social outcomes of patients. The observed outcome approach can complement other approaches to determining bed numbers at the national and local levels, and should be a priority for future health services research.

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.

Predicting security incidents in high secure male psychiatric care

PURPOSE

The contribution of environmental and organisational factors in predicting security incidents within a high secure male psychiatric setting is considered using a series of connected studies; a systematic literature review comprising 41 studies and five inquiries (Study 1) to identify core themes of likely importance; application of these themes to incident data through assessment of the ward culture, as perceived by 73 male psychiatric patients and 157 staff (Study 2); and detailed examination of noted relevant factors in the form of interpersonal style, meaningful activity and physical environmental characteristics in a study comprising 62 patients and 151 staff (Study 3). It was predicted that security incidents would be identified through inclusion of environmental and organisational factors.

RESULTS

The systematic review demonstrated the importance of accounting for staff characteristics, patient interactions, physical environment and meaningful activity. The subsequent study noted the importance of only specific aspects of the social environment, with the final study demonstrating that incidents were associated with controlling interpersonal styles of staff, lower perceived fairness, and less involvement in off-ward activities. Perception of fair treatment and off-ward activities mediated the staff interpersonal style and security incident relationship.

CONCLUSIONS

The research proposes a preliminary framework - the McKenna Framework for understanding Incidents in Secure Settings (M-FISS) - to explain the occurrence of security incidents in secure psychiatric care.

Risk Factors and Triggers That May Result in Patient-Initiated Violence on Inpatient Psychiatric Units: An Integrative Review

The aim of the present integrative review is to identify and describe risk factors and triggers that may result in patient-initiated violence on inpatient psychiatric units. Original studies were searched for in PubMed, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature. From the 826 identified publications, 18 were included for a synthesis. The results are presented in three themes, which demonstrate that patient characteristics, staff approach, and the ward environment are influencers that may trigger the emergence of violent incidents. Incidents are discussed from the theoretical framework of complexity science as dynamic, highly variable in manifestation, and adaptive, in that the forthcoming process and outcomes are highly dependent on how the surrounding environment responds. Our recommendation is that staff on inpatient wards recognize the myriad influencers that may trigger inpatient violence in a context of highly complex interactions.

Reduction of Involuntary Admissions in Patients With Severe Psychotic Disorders Treated in the ACCESS Integrated Care Model Including Therapeutic Assertive Community Treatment

Objective: The ACCESS treatment model offers assertive community treatment (ACT) embedded in an integrated care program to patients with severe psychotic disorders. Compared to standard care, it proved to be more effective in terms of service disengagement and other outcomes in patients with psychotic disorders over 12, 24, and 48 months. Many patients with severe mental disorders experience involuntary admissions which can be potentially traumatic. In this study, we assessed the effect of ACT on reducing involuntary admissions over an observation period of 4 years. Method: One hundred seventy-one patients treated in ACCESS were included in this study. The primary outcome was rate of involuntary admissions during 48 months. Secondary outcomes were differences between those with and without involuntary admissions in the 2 years prior to ACCESS regarding change of psychopathology, severity of illness, psychosocial functioning, quality of life, satisfaction with care, medication non-adherence, and service-disengagement. Results: Of 171 patients, 58 patients (33.9%) were involuntarily admitted to hospital in the past 2 years before entry. During the 4 years of treatment, 16 patients (9.4%) were involuntarily admitted to hospital which was a significantly lower rate compared to the 2 years before inclusion in ACCESS (p < .001). Comparing the two groups, larger improvements in severity of illness (p = .004) and functional status (p = .043) were detected in the group with no history of involuntary admissions. At 4-year follow-up, of the remaining patients, 69.2% (n = 81) were full adherent (p < .001), compared to 18.9% (n = 31) at baseline with no differences between the two groups over the study period (p = .25). Over 4 years, only 13 patients (13.2%) were service-disengaged due to non-practical reasons. Conclusions: In this long-term study, we were able to demonstrate a reduction in involuntary admissions in four treatment years compared to the 2 years prior to admission to the ACCESS model in patients with severe and mostly multiphase schizophrenia spectrum disorders and affective disorders with psychotic features. This may help prevent patients from suffering from a potentially traumatic experience during treatment in the psychiatric system.

Can "Model Projects of Need-Adapted Care" Reduce Involuntary Hospital Treatment and the Use of Coercive Measures?

Intensive outpatient models of need-adapted psychiatric care have been shown to reduce the length of hospital stays and to improve retention in care for people with severe mental illnesses. In contrast, evidence regarding the impact of such models on involuntary hospital treatment and other coercive measures in inpatient settings is still sparse, although these represent important indicators of the patients' wellbeing. In Germany, intensive models of care still have not been routinely implemented, and their effectiveness within the German psychiatric system is only studied in a few pioneering regions. An innovative model of flexible, assertive, need-adapted care established in Berlin, Germany, in 2014, treating unselected 14% of the catchment area's patients, was evaluated on the basis of routine clinical data. Records of n = 302 patients diagnosed with severe mental disorders, who had been hospitalized at least once during a 4-year-observational period, were analyzed in a retrospective individual mirror-image design, comparing the 2 years before and after inclusion in the model project regarding the time spent in hospital, the number and duration of involuntary hospital treatments and the use of direct coercive interventions like restraint or isolation. After inclusion to the project, patients spent significantly less time in hospital. Among patients treated on acute wards and patients with a diagnosis of psychosis, the number of patients subjected to provisional detention due to acute endangerment of self or others decreased significantly, as did the time spent under involuntary hospital treatment. The number of patients subjected to mechanical restraint, but not to isolation, on the ward decreased significantly, while the total number of coercive interventions remained unchanged. Findings suggest some potential of intensive models of need-adapted care to reduce coercive interventions in psychiatry. However, results must be substantiated by evidence from randomized-controlled trials and longer observation periods.

Characteristics of aggression among psychiatric inpatients by ward type in Japan: Using the Staff Observation Aggression Scale - Revised (SOAS-R)

Aggressive behaviour by psychiatric patients is a serious issue in clinical practice, and adequate management of such behaviour is required, with careful evaluation of the factors causing the aggression. To examine the characteristics of aggressive incidents by ward type, a cross-sectional descriptive study was conducted for 6 months between April 2012 and June 2013 using the Staff Observation Aggression Scale - Revised, Japanese version (SOAS-R) in 30 wards across 20 Japanese psychiatric hospitals. Participating wards were categorized into three types based on the Japanese medical reimbursement system: emergency psychiatric, acute psychiatric, and standard wards (common in Japan, mostly treating non-acute patients). On analyzing the 443 incidents reported, results showed significant differences in SOAS-R responses by ward type. In acute and emergency psychiatric wards, staff members were the most common target of aggression. In acute psychiatric wards, staff requiring patients to take medication was the most common provocation, and verbal aggression was the most commonly used means. In emergency psychiatric wards, victims felt threatened. In contrast, in standard wards, both the target and provocation of aggression were most commonly other patients, hands were used, victims reported experiencing physical pain, and seclusion was applied to stop their behaviour. These findings suggest that ward environment was an important factor influencing aggressive behaviour. Ensuring the quality and safety of psychiatric care requires understanding the characteristics of incidents that staff are likely to encounter in each ward type, as well as implementing efforts to deal with the incidents adequately and improve the treatment environment.

Patient Aggression and the Wellbeing of Nurses: A Cross-Sectional Survey Study in Psychiatric and Non-Psychiatric Settings

Wellbeing of nurses is associated with patient aggression. Little is known about the differences in these associations between nurses working in different specialties. We aimed to estimate and compare the prevalence of patient aggression and the associations between patient aggression and the wellbeing of nurses in psychiatric and non-psychiatric specialties (medical and surgical, and emergency medicine). A sample of 5288 nurses (923 psychiatric nurses, 4070 medical and surgical nurses, 295 emergency nurses) participated in the study. Subjective measures were used to assess both the occurrence of patient aggression and the wellbeing of nurses (self-rated health, sleep disturbances, psychological distress and perceived work ability). Binary logistic regression with interaction terms was used to compare the associations between patient aggression and the wellbeing of nurses. Psychiatric nurses reported all types of patient aggression more frequently than medical and surgical nurses, whereas nurses working in emergency settings reported physical violence and verbal aggression more frequently than psychiatric nurses. Psychiatric nurses reported poor self-rated health and reduced work ability more frequently than both of the non-psychiatric nursing groups, whereas medical and surgical nurses reported psychological distress and sleep disturbances more often. Psychiatric nurses who had experienced at least one type of patient aggression or mental abuse in the previous year, were less likely to suffer from psychological distress and sleep disturbances compared to medical and surgical nurses. Psychiatric nurses who had experienced physical assaults and armed threats were less likely to suffer from sleep disturbances compared to nurses working in emergency settings. Compared to medical and surgical nurses, psychiatric nurses face patient aggression more often, but certain types of aggression are more common in emergency settings. Psychiatric nurses have worse subjective health and work ability than both of the non-psychiatric nursing groups, while their psychiatric wellbeing is better and they have less sleep problems compared to medical and surgical nurses. Psychiatric nurses maintain better psychiatric wellbeing and experience fewer sleep problems than non-psychiatric nurses after events of exposure to patient aggression. This suggest that more attention should be given to non-psychiatric settings for maintaining the wellbeing of nurses after exposure to patient aggression.

Recovery-focussed care: How it can be utilized to reduce aggression in the acute mental health setting

Consumer aggression is common in the acute mental health inpatient setting. Mental health nurses can utilize a range of interventions to prevent aggression or reduce its impact on the person and others who have witnessed the event. Incorporating recovery-focussed care into clinical practice is one intervention, as it fosters collaborative partnerships with consumers. It promotes their engagement in decisions about their care and encourages self-management of their presenting behaviours. It also allows the consumer to engage in their personal recovery as their mental health improve. Yet there is a paucity of literature on how nurses can utilize recovery-focussed care with consumers who are hospitalized and in the acute phase of their illness. In the present study, we report the findings of a scoping review of the literature to identify how recovery-focussed care can be utilized by nurses to reduce the risk of consumer aggression. Thirty-five papers met the inclusion criteria for review. Four components were identified as central to the use of recovery-focussed care with consumers at risk of becoming aggressive: (i) seeing the person and not just their presenting behaviour; (ii) interact, don't react; (iii) coproduction to achieve identified goals; and (iv) equipping the consumer as an active manager of their recovery. The components equip nurses with strategies to decrease the risk of aggression, while encouraging consumers to self-manage their challenging behaviours and embark on their personal recovery journey. Further research is required to evaluate the translation of these components clinically in the acute care setting.

Interventions following a high violence risk assessment score: a naturalistic study on a Finnish psychiatric admission ward

BACKGROUND

Patient aggression and violence against staff members and other patients are common concerns in psychiatric units. Many structured clinical risk assessment tools have recently been developed. Despite their superiority to unaided clinical judgments, staff has shown ambivalent views towards them. A constant worry of staff is that the results of risk assessments would not be used. The aims of the present study were to investigate what were the interventions applied by the staff of a psychiatric admission ward after a high risk patient had been identified, how frequently these interventions were used and how effective they were.

METHODS

The data were collected in a naturalistic setting during a 6-month period in a Finnish psychiatric admission ward with a total of 331 patients with a mean age of 42.9 years (SD 17.39) suffering mostly from mood, schizophrenia-related and substance use disorders. The total number of treatment days was 2399. The staff assessed the patients daily with the Dynamic Appraisal of Situational Aggression (DASA), which is a structured violence risk assessment considering the upcoming 24 h. The interventions in order to reduce the risk of violence following a high DASA total score (≥4) were collected from the patients' medical files. Inductive content analysis was used.

RESULTS

There were a total of 64 patients with 217 observations of high DASA total score. In 91.2% of cases, at least one intervention aiming to reduce the violence risk was used. Pro re nata (PRN)-medication, seclusion and focused discussions with a nurse were the most frequently used interventions. Non-coercive and non-pharmacological interventions like daily activities associated significantly with the decrease of perceived risk of violence.

CONCLUSION

In most cases, a high score in violence risk assessment led to interventions aiming to reduce the risk. Unfortunately, the most frequently used methods were psychopharmacological or coercive. It is hoped that the findings will encourage the staff to use their imagination when choosing violence risk reducing intervention techniques.

Patient Violence Toward Psychiatric Health Care Workers in Israel as Viewed Through Incident Reports

BACKGROUND

Rates of violence perpetrated by patients toward health care workers are known to be higher in psychiatry than in other fields. Objective standardized reports of violent incidents may clarify this phenomenon.

OBJECTIVE

The purpose of this study was to assess the characteristics of patient violence, as evident from objective reports.

STUDY DESIGN

In this retrospective chart review study, conducted at a large mental health hospital in Israel between 2013 and 2015, reports of violent incidents perpetrated by people diagnosed with mental health problems against health care workers of the hospital were reviewed.

RESULTS

A total of 80 violent incidents were recorded. The findings outline the characteristics of a typical assailant, a typical victim, and a typical incident, and demonstrate associations between some of these characteristics.

CONCLUSIONS

This information may be beneficial for planning interventions for efficient coping with and prevention of violence at psychiatric inpatient facilities.

Violent events, ward climate and ideas for violence prevention among nurses in psychiatric wards: a focus group study

BACKGROUND

Patient violence against nurses in their work environments is a widespread global concern, particularly in the field of mental health care. A high prevalence of violent events impacts the well-being of nurses and may also impair overall ward climate. However, it has been proposed that nurses' use limited techniques to prevent patient violence, and, therefore, more comprehensive methods for dealing with patient violence are needed. There is still restricted understanding of the ward climate during the occurrence of a violent event as well as how these incidents could be more effectively prevented. This study aimed to explore nurses' experiences of violent events in psychiatric wards, give insight into ward climates and examine suggestions for violence prevention.

METHODS

This study employed a descriptive, exploratory design including focus groups (n = 5) and open-ended questions. The participants were registered and enrolled nurses (n = 22) working on three closed psychiatric in-patient wards in one Finnish hospital district. Focus groups were tape-recorded, transcribed and analyzed with inductive content analysis.

RESULTS

Nurses' experiences of violent events included a variety of warning signs and high-risk situations which helped them to predict forthcoming violence. Patient-instigated violent events were described as complicated situations involving both nurses and patients. When the wards were overloaded with work or emotions, or if nurses had become cynical from dealing with such events, well-being of nurses was impaired and nursing care was complicated. Suggestions for violence prevention were identified, and included, for example, more skilled interaction between nurses and patients and an increase in contact between nurses and patients on the ward.

CONCLUSIONS

This study revealed the complexity of violent events on psychiatric wards as well as the implications of these events on clinical practice development and training, administration and policy. A routine process is needed through which nurses' experiences and ideas concerning prevention of violent events are acknowledged.

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.

Inpatient aggression in community hospitals

Physical violence is a frequent occurrence in acute community psychiatry units worldwide. Violent acts by patients cause many direct injuries and significantly degrade quality of care. The most accurate tools for predicting near-term violence on acute units rely on current clinical features rather than demographic risk factors. The efficacy of risk assessment strategies to lower incidence of violence on acute units is unknown. A range of behavioral and psychopharmacologic treatments have been shown to reduce violence among psychiatric inpatients.

Characteristics of international staff victims of psychiatric patient assaults: review of published findings, 2000-2012

Psychiatric patient assaults on staff are a worldwide occupational hazard that results in human suffering and dollar cost expense. International research in the 1990s documented the frequent occurrence of these assaults. This present paper reviewed the published, international literature on staff victim assaults during the first decade of the new century. The findings indicate assaults on staff remain a serious worldwide issue as it was in the 1990s, even with new policy initiatives in place meant to reduce such violence. The findings by continents and a detailed methodological inquiry are presented.

Clinical and organizational factors related to the reduction of mechanical restraint application in an acute ward: an 8-year retrospective analysis

Background:

The purpose of this study was to describe the frequency of mechanical restraint use in an acute psychiatric ward and to analyze which variables may have significantly influenced the use of this procedure. Methods: This retrospective study was conducted in the Servizio Psichiatrico di Diagnosi e Cura (SPDC) of Modena Centro. The following variables of our sample, represented by all restrained patients admitted from 1-1-2005 to 31-12-2012, were analyzed: age, gender, nationality, psychiatric diagnoses, organic comorbidity, state and duration of admission, motivation and duration of restraints, nursing shift and hospitalization day of restraint, number of patients admitted at the time of restraint and institutional changes during the observation period. The above variables were statistically compared with those of all other non-restrained patients admitted to our ward in the same period. Results: Mechanical restraints were primarily used as a safety procedure to manage aggressive behavior of male patients, during the first days of hospitalization and night shifts. Neurocognitive disorders, organic comorbidity, compulsory state and long duration of admission were statistically significantly related to the increase of restraint use (p<.001, multivariate logistic regression). Institutional changes, especially more restricted guidelines concerning restraint application, were statistically significantly related to restraint use reduction (p<.001, chi2 test, multivariate logistic regression). Conclusion: The data obtained highlight that mechanical restraint use was influenced not only by clinical factors, but mainly by staff and policy factors, which have permitted a gradual but significant reduction in the use of this procedure through a multidimensional approach.

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.

Who is Subjected to Coercive Measures as a Psychiatric Inpatient? A Multi-Level Analysis

Background:

For a reduction in the use of coercive interventions it will be necessary to identify patients at risk. The aim of this study was to explore the impact of basic patient characteristics at admission, history within 24 hours before admission, and living conditions on the risk of experiencing coercive measures, controlling for ward characteristics in a multi-level approach.

Methods:

Patient characteristics of 3389 patients (1920 women) who had received inpatient treatment in 2007, data relating to coercive measures, and ward characteristics were extracted from the clinical basic documentation.

Results:

Patients with aggressive behaviour in the 24 hours prior to admission had a three times higher risk of coercive measures compared to non-aggressive patients. Severity of illness increased the risk of coercion markedly. With each level of severity, the risk of coercion was doubled. Voluntariness of stay appeared to be the best protective factor against coercive measures. If a patient stayed voluntarily, this reduced the risk of coercion by more than two thirds. No impact was found for living conditions.

Conclusions:

To identify patients at risk, it is most important to intensively monitor patients with aggressive behaviour prior to admission and patients with a greater severity of psychopathological symptoms.

Staff's perception of adolescent aggressive behaviour in four European forensic units: a qualitative interview study

BACKGROUND

Aggressive behaviour among patients is extremely common in forensic adolescent psychiatry compromising the safety of the treatment milieu and posing a treatment challenge to the staff. The staff's perception of aggression is likely to contribute to the aggression management practices among disturbed adolescents.

AIMS

To examine staff's perceptions of adolescent aggressive behaviour and factors contributing it.

METHODS

Qualitative interviews were conducted in four adolescent forensic units in four European countries. Data was analysed using qualitative content analysis.

FINDINGS

Aggressive behaviour was perceived to be verbal and physical in nature with various levels of severity. Several factors were perceived to contribute to aggressive acts, including adolescents' early life experiences. Participants mainly shared perceptions of adolescent aggressive behaviour in the four units studied.

CONCLUSIONS

The study provides new international knowledge about how staff perceive adolescent aggressive behaviour in the forensic setting. The shared understanding of adolescents' aggressive behaviour enables the implementation of safe, ethically sound and more consistent aggression management in clinical forensic practice. Reduced occurrence of aggression may improve the therapeutic milieu of the unit and may strengthen the staff's occupational health.

The relationship between level of training and accuracy of violence risk assessment

OBJECTIVE

Although clinical training programs aspire to develop competency in violence risk assessment, little research has examined whether level of training is associated with the accuracy of clinicians' evaluations of violence potential. This is the first study to compare the accuracy of risk assessments by experienced psychiatrists with those performed by psychiatric residents. It also examined the potential of a structured decision support tool to improve residents' risk assessments.

METHODS

The study used a retrospective case-control design. Medical records were reviewed for 151 patients who assaulted staff at a county hospital and 150 comparison patients. At admission, violence risk assessments had been completed by psychiatric residents (N=38) for 52 patients and by attending psychiatrists (N=41) for 249 patients. Trained research clinicians, who were blind to whether patients later became violent, coded information available at hospital admission by using a structured risk assessment tool-the Historical, Clinical, Risk Management-20 clinical subscale (HCR-20-C).

RESULTS

Receiver operating characteristic analyses showed that clinical estimates of violence risk by attending psychiatrists had significantly higher predictive validity than those of psychiatric residents. Risk assessments by attending psychiatrists were moderately accurate (area under the curve [AUC]=.70), whereas assessments by residents were no better than chance (AUC=.52). Incremental validity analyses showed that addition of information from the HCR-20-C had the potential to improve the accuracy of risk assessments by residents to a level (AUC=.67) close to that of attending psychiatrists.

CONCLUSIONS

Having less training and experience was associated with inaccurate violence risk assessment. Structured methods hold promise for improving training in risk assessment for violence.

Physical restraints in an Italian psychiatric ward: clinical reasons and staff organization problems

PURPOSE

To analyze physical restraint use in an Italian acute psychiatric ward, where mechanical restraint by belt is highly discouraged but allowed.

DESIGN AND METHODS

Data were retrospectively collected from medical and nursing charts, from January 1, 2005, to December 31, 2008. Physical restraint rate and relationships between restraints and selected variables were statistically analyzed.

FINDINGS

Restraints were statistically significantly more frequent in compulsory or voluntary admissions of patients with an altered state of consciousness, at night, to control aggressive behavior, and in patients with "Schizophrenia and other Psychotic Disorders" during the first 72 hr of hospitalization.

PRACTICAL IMPLICATIONS

Analysis of clinical and organizational factors conditioning restraints may limit its use.
