A randomized controlled trial of community-oriented and hospital-oriented care for discharged psychiatric patients: influence of personality disorder on police contacts

Police Officers' Ability in Recognizing Relevant Mental Health Conditions

The recognition of certain mental health conditions is important as this requires police officers to communicate and behave in an adjusted manner with affected individuals. The objective of the present study was to test police officers’ knowledge about mental health symptoms as a component of their mental health literacy (MHL) and to examine if police officers’ perceived knowledge corresponds with their actual knowledge. A questionnaire was used to assess for MHL representing mental health conditions which occur frequently in police requests (schizophrenia, bipolar disorder, depression, post-traumatic stress disorders, and emotionally unstable personality disorder). Furthermore, the questionnaire assessed the frequency of police requests, the officers’ perceived knowledge regarding mental disorders and their sense of feeling sufficiently trained to deal with these kinds of requests. Eighty-two police officers participated in the study. Police officers’ actual knowledge about mental health conditions did not correspond with their perceived knowledge. Participants revealed a moderately high level of overall knowledge which differed with regard to symptoms of each of the five mental health conditions. The mental status of a paranoid schizophrenia was best identified by the police officers and the majority correctly allocated the symptoms. Post-traumatic stress disorders and manic episodes were only identified by a minority of police offers. Police training geared to prepare for requests involving individuals with mental disorders should expand this limited knowledge transfer and focus on a broader variety of mental health conditions that police officers frequently encounter in requests.

Services for personality disorder: organisation for inclusion

Mental health services are not yet organised to allow patients with personality disorders easy access, and practitioners lack the necessary skills to implement effective treatment. A number of service models have developed, albeit without a clear evidence-base. These include sole-practitioner, divided-functions and specialist-team models. In general, a divided-functions or specialist-team model is probably best for reducing risk and improving outcomes. Both models present difficulties with integrating treatment, but these can be overcome by good communication. Good management of patients requires careful assessment of need and risk, a consistent approach, constancy of staff, team coherence and adequate in-patient support. Not all practitioners can treat patients with personality disorders and the interpersonal skills of the mental health professional may be crucial in maintaining a patient in treatment.

Co-morbidity of personality disorder in schizophrenia among psychiatric outpatients in China: data from epidemiologic survey in a clinical population

BACKGROUND

The reported rates of personality disorder (PD) in subjects with schizophrenia (SZ) are quite varied across different countries, and less is known about the heterogeneity of PD among subjects with SZ. We examined the co-morbidity of PD among patients who are in the stable phase of SZ.

METHOD

850 subjects were randomly sampled from patients diagnosed with SZ in psychiatric and psycho-counseling clinics at Shanghai Mental Health Center. Co-morbidity of PDs was assessed through preliminary screening and patients were administered several modules of the SCID-II. Evidence of heterogeneity was evaluated by comparing patients diagnosed with SZ with those who presented with either affective disorder or neurosis (ADN).

RESULTS

204 outpatients (24.0 %) in the stable phase of SZ met criteria for at least one type of DSM-IV PD. There was a higher prevalence of Cluster-A (odd and eccentric PD) and C (anxious and panic PD) PDs in SZ (around 12.0 %). The most prevalent PD was the paranoid subtype (7.65 %). Subjects with SZ were significantly more likely to have schizotypal PD (4.4 % vs. 2.1 %, p = 0.003) and paranoid PD (7.6 % vs. 5.4 %, p = 0.034), but much less likely to have borderline, obsessive-compulsive, depressive, narcissistic and histrionic PD.

CONCLUSIONS

These findings suggest that DSM-IV PD is common in patients with SZ than in the general population. Patterns of co-morbidity with PDs in SZ are different from ADN.

Crisis intervention for people with severe mental illnesses

BACKGROUND

A particularly difficult challenge for community treatment of people with serious mental illnesses is the delivery of an acceptable level of care during the acute phases of severe mental illness. Crisis-intervention models of care were developed as a possible solution.

OBJECTIVES

To review the effects of crisis-intervention models for anyone with serious mental illness experiencing an acute episode compared to the standard care they would normally receive. If possible, to compare the effects of mobile crisis teams visiting patients' homes with crisis units based in home-like residential houses.

SEARCH METHODS

We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials. There is no language, time, document type, or publication status limitations for inclusion of records in the register. This search was undertaken in 1998 and then updated 2003, 2006, 2010 and September 29, 2014.

SELECTION CRITERIA

We included all randomised controlled trials of crisis-intervention models versus standard care for people with severe mental illnesses that met our inclusion criteria.

DATA COLLECTION AND ANALYSIS

We independently extracted data from these trials and we estimated risk ratios (RR) or mean differences (MD), with 95% confidence intervals (CI). We assessed risk of bias for included studies and used GRADE to create a 'Summary of findings' table.

MAIN RESULTS

The update search September 2014 found no further new studies for inclusion, the number of studies included in this review remains eight with a total of 1144 participants. Our main outcomes of interest are hospital use, global state, mental state, quality of life, participant satisfaction and family burden. With the exception of mental state, it was not possible to pool data for these outcomes.Crisis intervention may reduce repeat admissions to hospital (excluding index admissions) at six months (1 RCT, n = 369, RR 0.75 CI 0.50 to 1.13, high quality evidence), but does appear to reduce family burden (at six months: 1 RCT, n = 120, RR 0.34 CI 0.20 to 0.59, low quality evidence), improve mental state (Brief Psychiatric Rating Scale (BPRS) three months: 2 RCTs, n = 248, MD -4.03 CI -8.18 to 0.12, low quality evidence), and improve global state (Global Assessment Scale (GAS) 20 months; 1 RCT, n = 142, MD 5.70, -0.26 to 11.66, moderate quality evidence). Participants in the crisis-intervention group were more satisfied with their care 20 months after crisis (Client Satisfaction Questionnaire (CSQ-8): 1 RCT, n = 137, MD 5.40 CI 3.91 to 6.89, moderate quality evidence). However, quality of life scores at six months were similar between treatment groups (Manchester Short Assessment of quality of life (MANSA); 1 RCT, n = 226, MD -1.50 CI -5.15 to 2.15, low quality evidence). Favourable results for crisis intervention were also found for leaving the study early and family satisfaction. No differences in death rates were found. Some studies suggested crisis intervention to be more cost-effective than hospital care but all numerical data were either skewed or unusable. We identified no data on staff satisfaction, carer input, complications with medication or number of relapses.

AUTHORS' CONCLUSIONS

Care based on crisis-intervention principles, with or without an ongoing homecare package, appears to be a viable and acceptable way of treating people with serious mental illnesses. However only eight small studies with unclear blinding, reporting and attrition bias could be included and evidence for the main outcomes of interest is low to moderate quality. If this approach is to be widely implemented it would seem that more evaluative studies are still needed.

A controlled trial of a cognitive skills program for personality-disordered offenders

OBJECTIVE

There is a need to find effective treatments for individuals with antisocial and borderline personality disorder who are known to be difficult to engage and treat. Many of these individuals share considerable overlap with symptoms of ADHD, hence this study aimed to evaluate the Reasoning and Rehabilitation ADHD program (R&R2 ADHD) among patients with severe personality disorder.

METHOD

A total of 31 males detained in a "dangerous and severe personality disorder" unit completed questionnaires at baseline and post treatment to assess social problem solving, violent attitudes, anger, ADHD symptoms, emotional control, and social functioning. A total of 16 patients participated in the group condition, and their scores were compared with 15 waiting-list controls who received treatment as usual.

RESULTS

In all, 76% of group participants completed the program. In contrast to controls, they showed significant improvements in scores with mainly medium effect sizes.

CONCLUSION

R&R2 ADHD was effective in a small sample of severely personality-disordered offenders.

Crisis intervention for people with severe mental illnesses

BACKGROUND

A particularly difficult challenge for community treatment of people with serious mental illnesses is the delivery of an acceptable level of care during the acute phases of severe mental illness. Crisis intervention models of care were developed as a possible solution.

OBJECTIVES

To review the effects of crisis intervention models for anyone with serious mental illness experiencing an acute episode, compared with 'standard care'.

SEARCH METHODS

We updated the 1998, 2003 and 2006 searches with a search of the Cochrane Schizophrenia Group's Register of trials (2010) which is based on regular searches of CINAHL, EMBASE, MEDLINE, and PsycINFO.

SELECTION CRITERIA

We included all randomised controlled trials of crisis intervention models versus standard care for people with severe mental illnesses.

DATA COLLECTION AND ANALYSIS

We independently extracted data from these trials and we estimated risk ratios (RR) or mean differences (MD), with 95% confidence intervals (CI). We assumed that people who left early from a trial had no improvement.

MAIN RESULTS

Three new studies have been found since the last review in 2006 to add to the five studies already included in this review. None of the previously included studies investigated crisis intervention alone; all used a form of home care for acutely ill people, which included elements of crisis intervention. However, one of the new studies focuses purely on crisis intervention as provided by Crisis Resolution Home Teams within the UK; the two other new studies investigated crisis houses i.e. residential alternatives to hospitalisation providing home-like environments.Crisis intervention appears to reduce repeat admissions to hospital after the initial 'index' crises investigated in the included studies, this was particularly so for mobile crisis teams supporting patients in their own homes.Crisis intervention reduces the number of people leaving the study early, reduces family burden, is a more satisfactory form of care for both patients and families and at three months after crisis, mental state is superior to standard care. We found no differences in death outcomes. Some studies found crisis interventions to be more cost effective than hospital care but all numerical data were either skewed or unusable. No data on staff satisfaction, carer input, complications with medication or number of relapses were available.

AUTHORS' CONCLUSIONS

Care based on crisis intervention principles, with or without an ongoing home care package, appears to be a viable and acceptable way of treating people with serious mental illnesses. If this approach is to be widely implemented it would seem that more evaluative studies are still needed.

Program planning and staff competencies for forensic assertive community treatment: ACT-eligible versus FACT-eligible consumers

PURPOSE

Forensic assertive community treatment (FACT) is a recent adaptation of the assertive community treatment (ACT) model; however, more information is needed about how FACT and ACT consumers differ and how FACT should be modified to accommodate these differences.

METHOD

Linked, multisystem administrative data from King County, Washington, were used to compare the demographic, clinical, and criminal justice characteristics of ACT- and FACT-eligible consumers.

RESULTS

FACT consumers were more likely to be male, persons of color, and had more complex clinical profiles. Also, some FACT consumers were incarcerated for sex offenses, and more than half had violent offenses.

CONCLUSIONS

Traditionally, ACT teams avoid serving consumers with personality disorders, violent consumers, and sex offenders; however, given increased use of mandated outpatient treatment and mental health courts, FACT teams may have less discretion to choose whom they serve. The addition of clinical interventions and other modifications may be particularly important for FACT teams.

Twenty-four hour care for schizophrenia

BACKGROUND

Despite modern treatment approaches and a focus on community care, there remains a group of people who cannot easily be discharged from psychiatric hospital directly into the community. Twenty-four hour residential rehabilitation (a 'ward-in-a-house') is one model of care that has evolved in association with psychiatric hospital closure programmes.

OBJECTIVES

To determine the effects of 24 hour residential rehabilitation compared with standard treatment within a hospital setting.

SEARCH STRATEGY

We searched the Cochrane Schizophrenia Group Trials Register (May 2002 and February 2004).

SELECTION CRITERIA

We included all randomised or quasi-randomised trials that compared 24 hour residential rehabilitation with standard care for people with severe mental illness.

DATA COLLECTION AND ANALYSIS

Studies were reliably selected, quality assessed and data extracted. Data were excluded where more than 50% of participants in any group were lost to follow-up. For binary outcomes we calculated the relative risk and its 95% confidence interval.

MAIN RESULTS

We identified and included one study with 22 participants with important methodological shortcomings and limitations of reporting. The two-year controlled study evaluated "new long stay patients" in a hostel ward in the UK. One outcome 'unable to manage in the placement' provided usable data (n=22, RR 7.0 CI 0.4 to 121.4). The trial reported that hostel ward residents developed superior domestic skills, used more facilities in the community and were more likely to engage in constructive activities than those in hospital - although usable numerical data were not reported. These potential advantages were not purchased at a price. The limited economic data was not good but the cost of providing 24 hour care did not seem clearly different from the standard care provided by the hospital - and it may have been less.

AUTHORS' CONCLUSIONS

From the single, small and ill-reported, included study, the hostel ward type of facility appeared cheaper and positively effective. Currently, the value of this way of supporting people - which could be considerable - is unclear. Trials are needed. Any 24 hour care 'ward-in-a-house' is likely to be oversubscribed. We argue that the only equitable way of providing care in this way is to draw lots as to who is allocated a place from the eligible group of people with serious mental illness. With follow-up of all eligible for the placements - those who were lucky enough to be allocated a place as well as people in more standard type of care - real-world evaluation could take place. In the UK further randomised control trials are probably impossible, as many of these types of facilities have closed. The broader lesson of this review is to ensure early and rigorous evaluation of fashionable innovations before they are superseded by new approaches.

A symptom level examination of the relationship between Cluster B personality disorders and patterns of criminality and violence in women

The psychometric properties and structure of the Cluster B Personality Disorder criteria (Antisocial, Borderline, Histrionic, and Narcissistic) are examined in a sample of 261 female inmates using a self-report screen followed by a full diagnostic interview. The results of the structural analyses in this sample demonstrated good internal consistency and convergence, but poor discriminant validity between disorders. An exploratory factor analysis found that the structure of these disorders was best accounted for by a four-factor solution that paralleled the Diagnostic and Statistical Manual (DSM-IV-TR; APA, 2000) classification scheme with some significant and notable exceptions. Using the factor scores generated from the factor analysis, the personality profiles of the women were compared with several behavioral indices, including instant offense, institutional infractions, and self-report violence and victimization within the prison. Of particular importance was the consistent relationship observed between narcissistic personality traits and threatening and violent behavior within the prison combined with the impulsive but less malignant presentation of antisocial personality traits among this sample of women. Results are discussed as they inform our understanding of the structural integrity of the four Cluster B diagnostic categories and the relationship of these personality disorders to different types of criminality and violence.

Violence in psychosis: estimating the predictive validity of readily accessible clinical information in a community sample

OBJECTIVE

This study sought to assess the validity of different combinations of readily available clinical information in predicting assaults by patients with psychosis, predominantly in the community. The combinations of information were: a) age and sex, b) age, sex and history of criminality/violence c) age, sex, history of violence and drug use and d) age, sex, history of violence, drug use and personality disorder.

METHOD

708 subjects were followed for 2 years. Assaults were measured using multiple sources of information. Prediction validity was measured using the area under the receiver operating curves (AUC) and the number needed to detain (NND). A simple prediction tool was developed.

RESULTS

The AUC values using the four combinations of information were a) 0.65, b) 0.70, c) 0.71, and d) 0.73. Prediction based on combination b), c), and d) implied a NND of 3. A rule based on c), the most accessible information, is suggested as a simple screening tool.

CONCLUSIONS

Readily available clinical information allowed the prediction of assault over 2 years, in a sample of general psychiatric patients with psychosis, with a level of predictive accuracy comparable to that described using more detailed risk assessment tools. The information used in the predictive model was: age, sex, having committed an assault in the last 2 years (self-report) and having used any drug in the last year (self-report).

The Quantification of Violence Scale: a simple method of recording significant violence

BACKGROUND

Although there are many rating scales recording the incidence and intensity of violence there are none that are specifically concerned with the measurement and assessment of severe violence.

AIMS

To develop a scale sensitive to variation centred on severe violence, establish its normative values, test its feasibility, and assess its reliability and validity in different populations.

METHOD

The Quantification of Violence Scale (QOVS) was developed in two stages. First, a list of 30 commonly experienced violent episodes in clinical psychiatric practice were evaluated and tested by weighting each episode by severity. Second, a numerical scale used to record the severity of the episode according to its degree of planning, intent and consequences. Violent episodes in two clinical populations were compared using the Modified Overt Aggression Scale (MOAS) and the preliminary version of the QOVS over periods up to 18 months, following which the numerical scale was developed.

RESULTS

Good (0.60-0.74) to Excellent (> 0.75) test-retest and inter-rater reliability agreement was obtained with both forms of the scale (intra-class correlations of 0.75 and 0.69 respectively), and similar agreement with MOAS scores was reached (0.67) in clinical populations. The scale was quick and easy to use in practice, and a score defining severe violence (9 on the numerical scale and 16 on the matched scale) was determined.

CONCLUSIONS

The QOVS, in its two forms, is a useful measure of recording significant violence in clinical and forensic practice.

Community mental health teams (CMHTs) for people with severe mental illnesses and disordered personality

BACKGROUND

Closure of asylums and institutions for the mentally ill, coupled with government policies focusing on reducing the number of hospital beds for people with severe mental illness in favour of providing care in a variety of non-hospital settings, underpins the rationale behind care in the community. A major thrust towards community care has been the development of community mental health teams (CMHT).

OBJECTIVES

To evaluate the effects of community mental health team (CMHT) treatment for anyone with serious mental illness compared with standard non-team management.

SEARCH STRATEGY

We searched The Cochrane Schizophrenia Group Trials Register (March 2006). We manually searched the Journal of Personality Disorders, and contacted colleagues at ENMESH, ISSPD and in forensic psychiatry.

SELECTION CRITERIA

We included all randomised controlled trials of CMHT management versus non-team standard care.

DATA COLLECTION AND ANALYSIS

We extracted data independently. For dichotomous data we calculated relative risks (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis, based on a fixed effects model. We calculated numbers needed to treat/harm (NNT/NNH) where appropriate. For continuous data, we calculated weighted mean differences (WMD) again based on a fixed effects model.

MAIN RESULTS

CMHT management did not reveal any statistically significant difference in death by suicide and in suspicious circumstances (n=587, 3 RCTs, RR 0.49 CI 0.1 to 2.2) although overall, fewer deaths occurred in the CMHT group. We found no significant differences in the number of people leaving the studies early (n=253, 2 RCTs, RR 1.10 CI 0.7 to 1.8). Significantly fewer people in the CMHT group were not satisfied with services compared with those receiving standard care (n=87, RR 0.37 CI 0.2 to 0.8, NNT 4 CI 3 to 11). Also, hospital admission rates were significantly lower in the CMHT group (n=587, 3 RCTs, RR 0.81 CI 0.7 to 1.0, NNT 17 CI 10 to 104) compared with standard care. Admittance to accident and emergency services, contact with primary care, and contact with social services did not reveal any statistical difference between comparison groups.

AUTHORS' CONCLUSIONS

Community mental health team management is not inferior to non-team standard care in any important respects and is superior in promoting greater acceptance of treatment. It may also be superior in reducing hospital admission and avoiding death by suicide. The evidence for CMHT based care is insubstantial considering the massive impact the drive toward community care has on patients, carers, clinicians and the community at large.

New frontiers in the role of hospitalization for patients with personality disorders

The question of hospitalization in patients who suffer from a borderline personality disorder is very contentious. Through a case-based approach, this review article highlights the issues that surround this controversy. It then reviews the current practice guidelines and examines the evidence for various forms of hospitalization. A synthesis of this information leads to practical recommendations for the management of this challenging population.

Crisis intervention for people with severe mental illnesses

BACKGROUND

A particularly difficult challenge for community treatment of people with serious mental illnesses is the delivery of an acceptable level of care during the acute phases of severe mental illness. Crisis intervention models of care were developed as a possible solution.

OBJECTIVES

Our objectives are to review the effects of a crisis intervention model for anyone with serious mental illness experiencing an acute episode, compared with 'standard care'.

SEARCH STRATEGY

We updated the 1998 and 2003 searches with a search of the Cochrane Schizophrenia Group's Register of trials (January 2006).

SELECTION CRITERIA

We included all randomised controlled trials of crisis intervention models versus standard care for people with severe mental illnesses.

DATA COLLECTION AND ANALYSIS

Working independently, we selected and critically appraised studies, extracted data and analysed on an intention-to-treat basis. Where possible and appropriate we calculated relative risk ratios (RR) and their 95% confidence intervals (CI), with the number needed to treat (NNT). We calculated Weighted Mean Differences (WMD) for continuous data.

MAIN RESULTS

Several home-care studies have been carried out recently but none of these met the inclusion criteria for this review. For the 2006 update we excluded four more studies (total excluded 25). Two other recent studies await assessment; we found no new studies to add to the five studies already included in this review. None of these included studies purely investigated crisis intervention; all used a form of home care for acutely ill people, which included elements of crisis intervention. Forty five percent of the crisis/home care group were unable to avoid hospital admission during their treatment period. Home care, however, may help avoid repeat admissions (n=465, 3 RCTs, RR 0.72 CI 0.54 to 0.92, NNT 11 CI 6 to 97), but these data are heterogeneous (I-squared 86%). Crisis/home care reduces the number of people leaving the study early (n=594, 4 RCTs, RR lost at 12 months 0.74 CI 0.56 to 0.98, NNT 13 CI 7 to 130), reduces family burden (n=120, 1 RCT, RR 0.34 CI 0.20 to 0.59, NNT 3 CI 2 to 4), and is a more satisfactory form of care for both patients and families. We found no differences in death or mental state outcomes. All studies found home care to be more cost effective than hospital care but all numerical data were either skewed or unusable. No data on staff satisfaction, carer input, compliance with medication or number of relapses were available.

AUTHORS' CONCLUSIONS

Home care crisis treatment, coupled with an ongoing home care package, is a viable and acceptable way of treating people with serious mental illnesses. If this approach is to be widely implemented it would seem that more evaluative studies are still needed.

The Social Functioning Questionnaire: A Rapid and Robust Measure of Perceived Functioning

BACKGROUND

The Social Functioning Questionnaire (SFQ), an eight-item selfreport scale (score range 0-24), was developed from the Social Functioning Schedule (SFS), a semi-structured interview which has been used primarily with non-psychotic patients and has good test-retest and inter-rater reliability as well as construct validity. The SFQ was developed following the need for a quick assessment of perceived social function.

AIMS

To give further details of old and new data sets from studies involving over 4000 subjects assessed with the SFQ illustrating its epidemiological and clinical associations.

METHOD

New data were analysed from a national epidemiological study, a comparison of key-worker and subject versions of the SFQ, and reanalysis of data from three earlier clinical studies, of psychiatric emergencies, general practice psychiatric patients and those with recurrent psychotic illnesses. These data were examined further to determine their range, their relationship to other clinical measures, and change over time in clinical trials.

RESULTS

The population mean score in 4164 subjects was 4.6 and the data from all studies suggested that a score of 10 or more indicated poor social functioning. Those presenting as psychiatric emergencies had the poorest social function (mean 11.4) and psychiatric patients from general practice the best function (mean 7.7) of the clinical populations. The eight item scores had a normal distribution in psychiatric populations and a skewed one in a normal population; scores were relatively stable over the short (weeks) and long-term (months), and were high in the presence of acute mental health disturbance and personality disorder, giving support to the validity of the scale. The results from a UK sample of a randomly selected population specifically weighted for ethnic minorities showed similar social function across groups.

The problem of severity in the classification of personality disorder

The articles in this series are very valuable but have one omission that is very important in clinical practice; they do not address the question of severity. In this article I argue that the measure of severity, using what are described as hybrid models, is a critical component of practice and can be recorded easily using standard systems, both existing and planned. In arguing this case I will use an exemplar, the Personality Assessment Schedule (PAS), mainly because we have so much data from this instrument, but emphasize that other assessment procedures can be easily adapted to produce similar severity assessments.

Crisis intervention for people with severe mental illnesses

BACKGROUND

A particularly difficult challenge for community treatment of people with serious mental illnesses is the delivery of an acceptable level of care during the acute phases of severe mental illness. Crisis intervention models of care were developed as a possible solution.

OBJECTIVES

To review the effects of a crisis intervention model for anyone with serious mental illness experiencing an acute episode, compared to 'standard care'.

SEARCH STRATEGY

Searches of 1998 were updated with a search of the Cochrane Schizophrenia Group's Register of trials (July 2003).

SELECTION CRITERIA

All randomised controlled trials of crisis intervention models versus standard care for people with severe mental illnesses.

DATA COLLECTION AND ANALYSIS

Working independently, reviewers selected and critically appraised studies, extracted data and analysed on an intention-to-treat basis. Where possible and appropriate we calculated risk ratios (RR) and their 95% confidence intervals (CI), with the number needed to treat (NNT). For continuous data Weighted Mean Differences (WMD) were calculated.

MAIN RESULTS

This 2003 update includes no new studies. Five studies, none purely investigating crisis intervention, are included and 21 excluded. All included trials used a form of home care for acutely ill people, which included elements of crisis intervention. 45% of the crisis/home care group were unable to avoid hospital admission during their treatment period. Home care, however, may help avoid repeat admissions (n = 465, 3 randomised controlled trials, RR 0.72 CI 0.54 to 0.92, NNT 11 CI 6 to 97), but these data are heterogeneous (I-squared 86%). Crisis/home care reduces the number of people leaving the study early (n = 594, 4 randomised controlled trials, RR lost at 12 months 0.74 CI 0.56 to 0.98, NNT 13 CI 7 to 130), reduces family burden (n = 120, 1 randomised controlled trial, RR 0.34 CI 0.20 to 0.59, NNT 3 CI 2 to 4), and is a more satisfactory form of care for both patients and families. We found no differences in death or mental state outcomes. All studies found home care to be more cost effective than hospital care but all data were either skewed or unusable. No data on staff satisfaction, carer input, compliance with medication and number of relapses were available.

REVIEWERS' CONCLUSIONS

Home care crisis treatment, coupled with an ongoing home care package, is a viable and acceptable way of treating people with serious mental illnesses. If this approach is to be widely implemented it would seem that more evaluative studies are needed.

Characteristics of teams, staff and patients: associations with outcomes of patients in assertive outreach

BACKGROUND

Little is known about what characteristics of teams, staff and patients are associated with a favourable outcome of severe mental illness managed by assertive outreach.

AIMS

To identify predictors of voluntary and compulsory admissions in routine assertive outreach services in the UK.

METHOD

Nine features of team organisation and policy, five variables assessing staff satisfaction and burn-out and eleven patient characteristics taken from the baseline data of the Pan-London Assertive Outreach Study were tested as predictors of voluntary and compulsory admissions within a 9-month follow-up period.

RESULTS

Weekend working, staff burn-out and lack of contact of the patient with out and lack of contact of the patient with other services were associated independently with a higher probability of both voluntary and compulsory admission. In addition, admissions in the past predicted further voluntary and compulsory admissions, and teams not working extended hours predicted compulsory admissions in the follow-up period.

CONCLUSIONS

Characteristics of team working practice, staff burn-out and patients' history are associated independently with outcome. Patient contact with other services is a positive prognostic factor.

Prevalence of personality disorder in alcohol and drug services and associated comorbidity

AIMS

To compare the prevalence of personality disorder in alcohol and drug populations with special attention to its impact on psychopathology and service characteristics.

DESIGN

Cross-sectional survey.

SETTING

Three alcohol and four drug services in four urban UK centres.

PARTICIPANTS

Two hundred and sixteen drug and 64 alcohol service patients randomly sampled from current treatment populations.

MEASUREMENTS

A treatment population census recorded demographic and diagnostic data. Patient interviews assessed the presence, cluster type and severity of personality disorder using the Quick Personality Assessment Schedule (PAS-Q). Other psychopathology was measured using the Comprehensive Psychopathological Rating Scale (CPRS). A case-note audit recorded psychotic psychopathology using the OPCRIT schedule and data regarding social morbidity.

FINDINGS

The overall prevalence of personality disorder was 37% in the drug service sample and 53% in the alcohol service sample. The distribution of severity and clusters differed markedly between the two samples. There was a significant association between the severity of personality disorder and psychopathology in both samples. Levels of morbidity associated with clusters B and C were similar. Clinical diagnosis of personality disorder showed high specificity but low sensitivity when compared to PAS-Q.

CONCLUSIONS

In both alcohol and drug service populations, personality disorder is associated with significantly increased rates of psychopathology and social morbidity that worsens with increasing severity of the disorder. Despite this, personality disorder is poorly identified by clinical staff. The PAS-Q may be useful as a clinical assessment tool in the substance misuse population for the early identification and management of patients with personality disorder.

Self-reported personality traits and disorders (DSM-IV) and risk of criminal recidivism: a prospective study

Assessment and management of criminal offenders require valid methods to recognize personality psychopathology and other risk and protective factors for recidivism. We prospectively explored the association between dimensional and categorical measures of personality disorder (PD) measured with the DSM-IV and ICD-10 Personality Questionnaire (DIP-Q, Ottosson et al., 1995) and registered reconvictions in adult offenders. One hundred and sixty-eight offenders consecutively referred for pre-sentencing forensic psychiatric evaluation in Sweden during 1995-1996 completed DIP-Q self-reports. The subjects received different types of sanctions and were followed for an average of 36 months after release from prison, discharge from a forensic psychiatric hospital, or onset of nondetaining sentences. Age-adjusted odds ratios revealed a 4.8 times higher risk for any recidivism and a 3.7 times higher risk for violent recidivism among subjects whose self-reports suggested a categorical diagnosis of antisocial PD as compared to offenders without antisocial PD. The remaining nine categorical DSM-IV PD diagnoses were not significantly related to recidivism. In dimensional analyses, each additional antisocial and schizoid PD symptom endorsed by participants at baseline increased the risk for violent reoffending. Our results suggest a relationship between self-reported behavioral instability and interpersonal dysfunction captured primarily by DSM-IV antisocial and schizoid PD constructs, and criminal re-offending also in a multi-problem sample of identified offenders.

Does co-morbid personality disorder increase the risk of suicidal behaviour in psychosis?

OBJECTIVE

To examine the association between co-morbid personality disorder (PD) and suicidal behaviour over a 2-year period in a sample of patients with psychosis.

METHOD

A total of 670 patients with established psychotic illness were interviewed using a battery of instruments including a screen for co-morbid PD. The prevalence of attempted and completed suicide was measured over the next 2 years using multiple data sources. Logistic regression was used to examine whether those with co-morbid PD were at greater risk of suicidal behaviour compared with others.

RESULTS

One hundred and eighty six patients (28%) were rated as having a co-morbid PD. After adjusting for all covariates, patients with co-morbid PD were significantly more likely to attempt or complete suicide over the 2-year period (adjusted odds ratio: 1.87; 95% CI: 1.02-3.42).

CONCLUSION

Co-morbid PD is independently associated with an increased risk of suicidal behaviour in psychosis. Early assessment of personality status should be part of the routine assessment of all psychiatric patients.

Impact of comorbid personality disorder on violence in psychosis: report from the UK700 trial

BACKGROUND

The impact of comorbid personality disorder on the occurrence of violence in psychosis has not been fully explored.

AIMS

To examine the association between comorbid personality disorder and violence in community-dwelling patients with psychosis.

METHOD

A total of 670 patients with established psychotic illness were screened for comorbid personality disorder. Physical assault was measured from multiple data sources over the subsequent 2 years. Logistic regression was used to assess whether the presence of comorbid personality disorder predicted violence in the sample.

RESULTS

A total of 186 patients (28%) were rated as having a comorbid personality disorder. Patients with comorbid personality disorder were significantly more likely to behave violently over the 2-year period of the trial (adjusted odds ratio=1.71, 95% CI 1.05-2.79).

CONCLUSIONS

Comorbid personality disorder is independently associated with an increased risk of violent behaviour in psychosis.

Treatment models for those with severe mental illness and comorbid personality disorder

BACKGROUND

Dual diagnosis of personality disorder and severe mental illness is an important clinical association that has been under-researched with regard to clinical management.

AIMS

To compare the outcomes of different treatment models.

METHOD

The outcome of patients with this combined diagnosis was compared in a systematic review of three randomised controlled trials in which different forms of community outreach treatment or intensive case management were compared with standard care.

RESULTS

The results from the three studies showed that the outcome of comorbid diagnoses was worse than that of single diagnoses. Although assertive approaches reduced in-patient care, they sometimes did so at the expense of increasing social dysfunction and behavioural disturbance.

CONCLUSIONS

For those with comorbid severe mental illness and personality disorder, the policy of assertive outreach and care in community settings may be inappropriate for both public and patients unless modified to take account of the special needs of this group.
