Acceptability and use of coercive methods across differing service configurations with and without seclusion and/or psychiatric intensive care units.

AIMS: The aim of this study was to compare across different service configurations the acceptability of containment methods to acute ward staff and the speed of initiation of manual restraint. BACKGROUND: One of the primary remits of acute inpatient psychiatric care is the reduction in risks. Where risks are higher than normal, patients can be transferred to a psychiatric intensive care unit or placed in seclusion. The abolition or reduction in these two containment methods in some hospitals may trigger compensatory increases in other forms of containment which have potential risks. How staff members manage risk without access to these facilities has not been systematically studied. DESIGN: The study applied a cross-sectional design. METHODS: Data were collected from 207 staff at eight hospital sites in England between 2013 - 2014. Participants completed two measures; the first assessing the acceptability of different forms of containment for disturbed behaviour and the second assessing decision-making in relation to the need for manual restraint of an aggressive patient. RESULTS: In service configurations with access to seclusion, staff rated seclusion as more acceptable and reported greater use of it. Psychiatric intensive care unit acceptability and use were not associated with its provision. Where there was no access to seclusion, staff were slower to initiate restraint. There was no relationship between acceptability of manual restraint and its initiation. CONCLUSION: Tolerance of higher risk before initiating restraint was evident in wards without seclusion units. Ease of access to psychiatric intensive care units makes little difference to restraint thresholds or judgements of containment acceptability.

Predictors of effective de-escalation in acute inpatient psychiatric settings.

AIMS AND OBJECTIVES: To explore the factors that influence the use of de-escalation and its success in halting conflict in acute psychiatric inpatient setting. BACKGROUND: De-escalation is the use of verbal and nonverbal communication to reduce or eliminate aggression and violence during the escalation phase of a patient's behaviour. Although de-escalation is a first-line intervention in aggression management in acute psychiatric settings, little is known about the use or effectiveness of this technique. DESIGN: A retrospective case note analysis. METHODS: For each patient (n = 522), their involvement in conflict (e.g. aggression) or containment (e.g. coerced medication) during the first two weeks of their admission was recorded. The frequency and order of the conflict and containment events were identified during each shift. The sequences of events occurring in shifts involving de-escalation were analysed. Sequences where de-escalation ended the pattern of conflict or containment were categorised as 'successful', and all others were categorised as 'unsuccessful'. RESULTS: Over half of patients (53%) experienced de-escalation during the first two weeks of admission, with the majority of these (37%) experiencing multiple episodes. De-escalation was successful in approximately 60% of cases. Successful de-escalations were preceded by fewer, and less aggressive, conflict events, compared with unsuccessful de-escalations, which were most frequently followed by administration of pro re nata medication. Patients with a history of violence were more likely to experience de-escalation, and it was more likely to be unsuccessful. CONCLUSIONS: De-escalation is frequently effective in halting a sequence of conflict in acute inpatient settings, but patients with a history of violence may be specifically challenging. RELEVANCE TO CLINICAL PRACTICE: These findings provide support for de-escalation in practice but suggest that nurses may lack confidence in using the technique when the risk of violence is greater. Providing evidence-based staff training may improve staff confidence in the use of this potentially powerful technique.

Results of a pilot randomised controlled trial to measure the clinical and cost effectiveness of peer support in increasing hope and quality of life in mental health patients discharged from hospital in the UK.

BACKGROUND: Mental health patients can feel anxious about losing the support of staff and patients when discharged from hospital and often discontinue treatment, experience relapse and readmission to hospital, and sometimes attempt suicide. The benefits of peer support in mental health services have been identified in a number of studies with some suggesting clinical and economic gains in patients being discharged. METHODS: This pilot randomised controlled trial with economic evaluation aimed to explore whether peer support in addition to usual aftercare for patients during the transition from hospital to home would increase hope, reduce loneliness, improve quality of life and show cost effectiveness compared with patients receiving usual aftercare only, with follow-up at one and three-months post-discharge. RESULTS: A total of 46 service users were recruited to the study; 23 receiving peer support and 23 in the care-as-usual arm. While this pilot trial found no statistically significant benefits for peer support on the primary or secondary outcome measures, there is an indication that hope may be further increased in those in receipt of peer support. The total cost per case for the peer support arm of the study was £2154 compared to £1922 for the control arm. The mean difference between costs was minimal and not statistically significant. However, further analyses demonstrated that peer support has a reasonably high probability of being more cost effective for a modest positive change in the measure of hopelessness. Challenges faced in recruitment and follow-up are explored alongside limitations in the delivery of peer support. CONCLUSIONS: The findings suggest there is merit in conducting further research on peer support in the transition from hospital to home consideration should be applied to the nature of the patient population to whom support is offered; the length and frequency of support provided; and the contact between peer supporters and mental health staff. There is no conclusive evidence to support the cost effectiveness of providing peer support, but neither was it proven a costly intervention to deliver. The findings support an argument for a larger scale trial of peer support as an adjunct to existing services. TRIAL REGISTRATION: Current Controlled Trials ISRCTN74852771.

Patients subject to high levels of coercion: staff's understanding.

Measures to keep staff and patients safe (containment) frequently involve coercion. A small proportion of patients is subject to a large proportion of containment use. To reduce the use of containment, we need a better understanding of the circumstances in which it is used and the understandings of patients and staff. Two sweeps were made of all the wards, spread over four hospital sites, in one large London mental health organization to identify patients who had been subject to high levels of containment in the previous two weeks. Data were then extracted from their case notes about their past history, current problem behaviours, and how they were understood by the patients involved and the staff. Nurses and consultant psychiatrists were interviewed to supplement the information from the case records. Twenty-six heterogeneous patients were identified, with many ages, genders, diagnoses, and psychiatric specialities represented. The main problem behaviours giving rise to containment use were violence and self-harm. The roots of the problem behaviours were to be found in severe psychiatric symptoms, cognitive difficulties, personality traits, and the implementation of the internal structure of the ward by staff. Staff's range and depth of understandings was limited and did not include functional analysis, defence mechanisms, specific cognitive assessment, and other potential frameworks. There is a need for more in-depth assessment and understanding of patients' problems, which may lead to additional ways to reduce containment use.

Identification of the "minimal triangle" and other common event-to-event transitions in conflict and containment incidents.

Although individual conflict and containment events among acute psychiatric inpatients have been studied in some detail, the relationship of these events to each other has not. In particular, little is known about the temporal order of events for individual patients. This study aimed to identify the most common pathways from event to event. A sample of 522 patients was recruited from 84 acute psychiatric wards in 31 hospital locations in London and the surrounding areas during 2009-2010. Data on the order of conflict and containment events were collected for the first two weeks of admission from patients' case notes. Event-to-event transitions were tabulated and depicted diagrammatically. Event types were tested for their most common temporal placing in sequences of events. Most conflict and containment occurs within and between events of the minimal triangle (verbal aggression, de-escalation, and PRN medication), and the majority of these event sequences conclude in no further events; a minority transition to other, more severe, events. Verbal abuse and medication refusal were more likely to start sequences of disturbed behaviour. Training in the prevention and management of violence needs to acknowledge that a gradual escalation of patient behaviour does not always occur. Verbal aggression is a critical initiator of conflict events, and requires more detailed and sustained research on optimal management and prevention strategies. Similar research is required into medication refusal by inpatients.

Measurement and monitoring of health care worker aggression exposure.

Aggression exposure is highly prevalent in healthcare workers, and is a complex problem that negatively impacts patient and worker safety and health. Typically only events of high severity (e.g., use of physical restraint or incident reports) are monitored in healthcare settings. Unfortunately, these events are likely a small fraction of all aggressive events that range from verbal to physical. Improved measurement and monitoring of healthcare worker aggression exposure may lead to improved patient and worker safety and health. This article provides an overview of aggression exposure in healthcare and reviews the measurement of aggression, including challenges and common measures. Discussion of a pilot study presents insights gained from using a novel measure of aggression, handheld counters. The conclusion offers implications for research and clinical practice.

Psychiatric patients' views on why their involuntary hospitalisation was right or wrong: a qualitative study.

PURPOSE: To explore involuntary patients' retrospective views on why their hospitalisation was right or wrong. METHODS: Involuntary patients were recruited from 22 hospitals in England and interviewed in-depth. The study drew on grounded theory and thematic analysis. RESULTS: Most of the patients felt mentally unwell before admission and out of control during their treatment. Despite these common experiences, three groups of patients with distinct views on their involuntary hospitalisation were identified: those who believed that it was right, those who thought it was wrong and those with ambivalent views. Those with retrospectively positive views believed that hospitalisation ensured that they received treatment, averted further harm and offered them the opportunity to recover in a safe place. They felt that coercion was necessary, as they could not recognise that they needed help when acutely unwell. Those who believed that involuntary admission was wrong thought that their problems could have been managed through less coercive interventions, and experienced hospitalisation as an unjust infringement of their autonomy, posing a permanent threat to their independence. Patients with ambivalent views believed that they needed acute treatment and that hospitalisation averted further harm. Nonetheless, they thought that their problems might have been managed through less coercive community interventions or a shorter voluntary hospitalisation. CONCLUSIONS: The study illustrates why some patients view their involuntary hospitalisation positively, whereas others believe it was wrong. This knowledge could inform the development of interventions to improve patients' views and treatment experiences.

Managing risk and conflict behaviours in acute psychiatry: the dual role of constant special observation.

AIMS: This is a report of a study of events before and after the use of constant special observation on acute psychiatric wards, and the characteristics of patients who received it. BACKGROUND: Constant special observation is a method of preventing acutely disturbed inpatients from harming themselves or others. It has been characterized as impersonal, intrusive and non-therapeutic. The circumstances of its use and place in broader intervention strategies are not well understood. METHODS: A sample of 522 patients were recruited from 84 acute psychiatric wards in 31 hospital locations in London and surrounding areas during 2009-2010. Data were collected for the first 2 weeks of admission from patients' case notes. RESULTS: Sixteen per cent of patients received constant special observation during the first 2 weeks in hospital (7% at the point of admission and 11% after admission), but with variation between hospitals. Absconding, violence and self-harm were the most common events to precede constant special observation during a shift. Other methods of containment, especially intermittent special observation, were frequently tried first. Episodes of constant special observation often involved de-escalation and extra medication. Aggression was more prominent during than before constant special observation. Attempted suicides were limited to postadmission episodes. CONCLUSION: Constant special observation is usually used in combination with other forms of containment, irrespective of when it is initiated. Placing patients considered at risk of suicide under constant special observation on admission may have a protective effect.

The scope for replacing seclusion with time out in acute inpatient psychiatry in England.

BACKGROUND: The use of seclusion is unpalatable to nurses and frequently unpleasant for patients. Time out is rated by nurses and patients as more acceptable. Several countries have initiated exercises to reduce the use of seclusion, but England has not. METHODS: In this study, data were collected on the sequence of conflict (aggression, rule breaking, absconding etc.) and containment (coerced medication, restraint, special observation etc., including time out and seclusion) for the first 2 weeks of 522 acute admissions on 84 wards in 31 English hospitals between June 2009 and March 2010. Data were analysed to describe what preceded and followed time out and seclusion episodes in a nursing shift. RESULTS: Seclusion was used with 7·5% of patients, and time out with 15·5%. Both containment methods were used with similar patients in similar circumstances, and both brought disturbed behaviour to a close in half of the cases. Some seclusion appeared to follow less serious disturbed behaviour. There was an important variation in rates of seclusion between hospitals. Seclusion and time out had equally good outcomes in the management of physical violence to others. CONCLUSIONS: There is good evidence that seclusion rates can be reduced safely, and time out can sometimes be used as a substitute. A national registration and reporting system should be introduced in England, and serious efforts made to reduce seclusion use in hospitals where rates are high.

Conflict and containment events in inpatient psychiatric units.

AIMS AND OBJECTIVES: To describe the types and frequency of conflict behaviours exhibited by patients during the first 2 weeks of admission to acute psychiatric units, the methods staff use to manage them and bring to the surface underlying common patterns. BACKGROUND: Many studies have investigated the prevalence and impact of psychiatric inpatient aggression. Much of the research to date has studied conflict and containment behaviours separately; however, some studies have reported relationships between certain behaviours suggesting that there are complex causal links between conflict and containment behaviours. DESIGN: A cross-sectional survey of conflict and containment events. METHODS: Nursing notes were accessed for 522 patients during the first 2 weeks of admission, in 84 wards in 31 hospitals in the South East of England. Conflict and containment events occurring during this period were recorded retrospectively. RESULTS: Factor analysis revealed six patterns of conflict behaviour, which were related to containment methods and patient demographic factors. These factors confirm some previously reported patterns of conflict. CONCLUSIONS: This study brings to light underlying common patterns of disruptive behaviour by psychiatric inpatients. The reasons for these remain obscure, but may relate to (1) national variations in policy and practice shaping static structural differences of interest between patients and staff and (2) normal developmental age and gender-specific behaviours. RELEVANCE TO CLINICAL PRACTICE: Conflict behaviour patterns may be differently motivated and therefore require different management strategies by staff. There is a need for awareness by clinical staff to the fact that different types of conflict behaviours may be co-occurring or indicative of each other. Clinical staff should consider that implementation of and changes to hospital policies have the potential to change the nature and frequencies of certain conflict behaviours by patients.

Patient characteristics and behaviours associated with self-harm and attempted suicide in acute psychiatric wards.

AIMS AND OBJECTIVES: The study examined events before and after incidents of self-harm and attempted suicide and the characteristics of patients who engage in these behaviours. BACKGROUND: Psychiatric inpatient populations have an elevated risk of self-harm and suicide, but relatively little is known about the circumstances of these events during an admission. DESIGN: Retrospective case note analysis. METHOD: Data were collected on conflict (aggression, rule breaking, etc.) and containment (coerced medication, restraint, etc.) during the first two weeks of admission for a sample of 522 acute psychiatric inpatients. RESULTS: One in 10 patients self-harmed, and 4% attempted suicide. Aggression, attempting to leave the ward without permission and medication refusal were frequent precursors to incidents. Pro re nata medication and de-escalation were the most frequent interventions to follow an incident. Self-harm and attempted suicides during the current admission were significantly associated with younger age and a history of self-harm. CONCLUSIONS: A minority of the sample were involved in these behaviours, but incidents occurred soon after admission and sometimes repeatedly during the course of a day. Assessment of risk should be completed as early as possible. RELEVANCE TO CLINICAL PRACTICE: At-risk patients should be monitored for signs of withdrawal from ward activity, wanting to leave the ward without permission or non-compliance with medication to enable early intervention.

The relationship between leadership, teamworking, structure, burnout and attitude to patients on acute psychiatric wards.

BACKGROUND: Conflict (aggression, substance use, absconding, etc.) and containment (coerced medication, manual restraint, etc.) threaten the safety of patients and staff on psychiatric wards. Previous work has suggested that staff variables may be significant in explaining differences between wards in their rates of these behaviours, and that structure (ward organisation, rules and daily routines) might be the most critical of these. This paper describes the exploration of a large dataset to assess the relationship between structure and other staff variables. METHODS: A multivariate cross-sectional design was utilised. Data were collected from staff on 136 acute psychiatric wards in 26 NHS Trusts in England, measuring leadership, teamwork, structure, burnout and attitudes towards difficult patients. Relationships between these variables were explored through principal components analysis (PCA), structural equation modelling and cluster analysis. RESULTS: Principal components analysis resulted in the identification of each questionnaire as a separate factor, indicating that the selected instruments assessed a number of non-overlapping items relevant for ward functioning. Structural equation modelling suggested a linear model in which leadership influenced teamwork, teamwork structure; structure burnout; and burnout feelings about difficult patients. Finally, cluster analysis identified two significantly distinct groups of wards: the larger of which had particularly good leadership, teamwork, structure, attitudes towards patients and low burnout; and the second smaller proportion which was poor on all variables and high on burnout. The better functioning cluster of wards had significantly lower rates of containment events. CONCLUSION: The overall performance of staff teams is associated with differing rates of containment on wards. Interventions to reduce rates of containment on wards may need to address staff issues at every level, from leadership through to staff attitudes.

The relationship between substance use and exit security on psychiatric wards.

AIM: In this paper we report on the rates of drug/alcohol use on acute psychiatric wards in relation to levels and intensity of exit security measures. BACKGROUND: Many inpatient wards have become permanently locked, with staff concerned about the risk of patients leaving the ward and harming themselves or others, and of people bringing illicit substances into the therapeutic environment. METHODS: In 2004/2005, a cross sectional survey on 136 acute psychiatric wards across three areas of England was undertaken. A comprehensive range of data including door locking and drug/alcohol use were collected over 6 months on each ward. In 2006, supplementary data on door locking and exit security were collected. Door locking, additional exit security measures and substance misuse rates of the 136 wards were analysed and the associations between these were investigated. RESULTS: No consistent relationships were found with exit security features, intensity of drug/alcohol monitoring procedures, or the locking of the ward door. There were indications that use of breath testing for alcohol might reduce usage and that the use of 'sniffer' dogs was associated with greater alcohol use. CONCLUSION: Greater exit security or locking of the ward door had no influence on rates of use of alcohol or illicit drugs by inpatients and thus cannot form part of any strategy to control substance use by inpatients. There are some grounds to believe that a greater use of screening might help reduce the frequency of alcohol/substance use on wards and may lead to a reduction in verbal abuse.

The profile of absconding psychiatric inpatients in Australia.

AIMS AND OBJECTIVES: The purpose of this study was to examine absconding behaviour (a patient leaving the hospital without permission) in acute and rehabilitation wards of one Australian psychiatric institution to describe the characteristics of the absconding patient and these events. BACKGROUND: Absconding is a significant issue in psychiatric inpatient settings, with risks that include patient harm, aggression and violence. In spite of this, limited research has been conducted in Australia on patients who abscond while receiving psychiatric care. DESIGN: The study was a retrospective descriptive analysis. METHOD: Absconding events from three acute and seven rehabilitation wards over a 12-month period were studied. RESULTS: The rate of absconding events by detained patients was 20.82%. Gender was not significantly associated with absconding, although 61.19% of those who absconded were men diagnosed with schizophrenic disorders. Over half of acute care patients who absconded left during their first 21-day detention order. More than half of absconding events were by patients that absconded more than once. There was limited support for the efficacy of locking ward doors. Age and diagnosis emerged as particularly important factors to consider. DISCUSSION: The study revealed that men are not more likely to abscond than women, that locking ward doors does not deter the determined absconders and that once a person has absconded, they are more likely to do so again. Younger patients and those with a schizophrenic disorder may be particularly likely to abscond. There also appears to be a link between continuing detention orders and an absconding event. CONCLUSIONS: Findings provide new data about the profile of absconding patients in Australia. Exploration of the reasons why patients abscond and why many do so repeatedly warrants further investigation. RELEVANCE TO CLINICAL PRACTICE: Risk management approaches taking into account factors associated with absconding could be trialled to reduce the incidence of absconding in psychiatric inpatient settings.

Suicide inside: a systematic review of inpatient suicides.

The literature on inpatient suicides was systematically reviewed. English, German, and Dutch articles were identified by means of the electronic databases PsycInfo, Cochrane, Medline, EMBASE psychiatry, CINAHL, and British Nursing Index. In total, 98 articles covering almost 15,000 suicides were reviewed and analyzed. Rates and demographic features connected to suicides varied substantially between articles, suggesting distinct subgroups of patients committing suicide (e.g., depressed vs. schizophrenic patients) with their own suicide determinants and patterns. Early in the admission is clearly a high-risk period for suicide, but risk declines more slowly for patients with schizophrenia. Suicide rates were found to be associated with admission numbers, and as expected, previous suicidal behavior was found to be a robust predictor of future suicide. The methods used for suicide are linked to availability of means. Timing and location of suicides seem to be associated with absence of support, supervision, and the presence of family conflict. Although there is a strong notion that suicides cluster in time, clear statistical evidence for this is lacking. For prevention of suicides, staff need to engage with patients' family problems, and reduce absconding without locking the door. Future research should take into account the heterogeneous subgroups of patients who commit suicide, with case-control studies addressing these separately.

The practice of seclusion and time-out on English acute psychiatric wards: the City-128 Study.

BACKGROUND: Seclusion is widely used internationally to manage disturbed behavior by psychiatric patients, although many countries are seeking to reduce or eliminate this practice. Time-out has been little described and almost completely unstudied. AIM AND METHOD: To assess the relationship of seclusion and time-out to conflict behaviors, the use of containment methods, service environment, physical environment, patient routines, staff characteristics, and staff group variables. Data from a multivariate cross-sectional study of 136 acute psychiatric wards in England were used to conduct this analysis. RESULTS: Seclusion is used infrequently on English acute psychiatric wards (0.05 incidents per day), whereas time-out use was more frequent (0.31 incidents per day). Usage of seclusion was strongly associated with the availability of a seclusion room. Seclusion was associated with aggression, alcohol use, absconding, and medication refusal, whereas time-out was associated with these and other more minor conflict behaviors. Both were associated with the giving of "as required" medication, coerced intramuscular medication, and manual restraint. Relationships with exit security for the ward were also found. CONCLUSIONS: Given its low usage rate, the scope for seclusion reduction in English acute psychiatry may be small. Seclusion reduction initiatives need to take a wider range of factors into account. Some substitution of seclusion with time-out may be possible, but a rigorous trial is required to establish this. The safety of intoxicated patients in seclusion requires more attention.

A review of interventions to reduce mechanical restraint and seclusion among adult psychiatric inpatients.

This review examines the nature and effectiveness of interventions to reduce the use of mechanical restraint and seclusion among adult psychiatric inpatients. Thirty-six post-1960 empirical studies were identified. The interventions were diverse, but commonly included new restraint or seclusion policies, staffing changes, staff training, case review procedures, or crisis management initiatives. Most studies reported reduced levels of mechanical restraint and/or seclusion, but the standard of evidence was poor. The research did not address which programme components were most successful. More attention should be paid to understanding how interventions work, particularly from the perspective of nursing staff, an issue that is largely overlooked.

Safety and security in acute admission psychiatric wards in Ireland and London: a comparative study.

AIMS AND OBJECTIVES: The comparative element of this study is to describe safety and security measures in psychiatric acute admission wards in the Republic of Ireland and London; to describe differences and similarities in terms of safety and security patterns in the Republic of Ireland and London; and to make recommendations on safety and security to mental health services management and psychiatric nurses. BACKGROUND: Violence is a serious problem in psychiatric services and staff experience significant psychological reactions to being assaulted. Health and Safety Authorities in the UK and Ireland have expressed concern about violence and assault in healthcare, however, there remains a lack of clarity on matters of procedure and policy pertaining to safety and security in psychiatric hospitals. DESIGN: A descriptive survey research design was employed. METHODS: Questionnaires were circulated to all acute wards in London and in Ireland and the resulting data compared. RESULTS: A total of 124 psychiatric wards from London and 43 wards from Ireland were included in this study and response rates of 70% (London) and 86% (Ireland) were obtained. Differences and similarities in safety and security practices were identified between London and Ireland, with Irish wards having generally higher and more intensive levels of security. CONCLUSIONS: There is a lack of coherent policy and procedure in safety and security measures across psychiatric acute admission wards in the Republic of Ireland and London. Given the trends in European Union (EU) regulation, there is a strong argument for the publication of acceptable minimum guidelines for safety and security in mental health services across the EU. RELEVANCE TO CLINICAL PRACTICE: There must be a concerted effort to ensure that all policy and procedure in safety and security is founded on evidence and best practice. Mental health managers must establish a review of work safety and security procedures and practices. Risk assessment and environmental audits of all mental health clinical environments should be mandatory.

The demography of nurses and patients on acute psychiatric wards in England.

AIMS AND OBJECTIVES: To describe the ethnic and demographic composition of staff and patients on acute psychiatric wards in England. BACKGROUND: A significant proportion of the UK population (7.6%) belong to an ethnic minority and there are concerns that ethnic minority patients are not well served by psychiatry, in particular that they are subject to excessive force and coercion. DESIGN: Survey of a random sample of psychiatric wards in three regions. METHODS: A survey was conducted of staff (n = 1536) and patients (n = 11,128) on 136 acute admission psychiatric wards. RESULTS: Ethnic minority patients were more likely to be admitted with a diagnosis of schizophrenia, younger, more likely to be admitted for a risk of harm to others and more likely to be legally detained. The association between ethnic minority status and detention remains, even when risk, age, gender and diagnosis are taken into account. Ethnic minority patients come from areas of greater social deprivation and fragmentation. Ethnic concordance between staff and patients varies, but the greatest difference is found in London where the proportion of minority staff is greater than the proportion of minority patients. CONCLUSIONS: There continues to be evidence that ethnic minority patients are subject to an excessive amount of legal coercion in English mental health services. However, the proportion of staff belonging to an ethnic minority is greater than the proportion of patients. RELEVANCE TO CLINICAL PRACTICE: Solutions to the problem of excessive use of legal coercion with ethnic minority patients need to be found. Changes of recruitment strategies are required if concordance is to be achieved.

Identifying key factors associated with aggression on acute inpatient psychiatric wards.

Aggressive behaviour is a critical issue for modern acute psychiatric services, not just because of the adverse impact it has on patients and staff, but also because it puts a financial strain on service providers. The aim of this study was to assess the relationship of patient violence to other variables: patient characteristics, features of the service and physical environment, patient routines, staff factors, the use of containment methods, and other patient behaviours. A multivariate cross sectional design was utilised. Data were collected for a six month period on 136 acute psychiatric wards in 26 NHS Trusts in England. Multilevel modelling was conducted to ascertain those factors most strongly associated with verbal aggression, aggression toward objects, and physical aggression against others. High levels of aggression were associated with a high proportion of patients formally detained under mental health legislation, high patient turnover, alcohol use by patients, ward doors being locked, and higher staffing numbers (especially qualified nurses). The findings suggest that the imposition of restrictions on patients exacerbates the problem of violence, and that alcohol management strategies may be a productive intervention. Insufficient evidence is available to draw conclusions about the nature of the link between staffing numbers and violence.
