Legal and human rights issues in the use of electronic monitoring (using GPS 'tracking' technology) in forensic mental health settings in the UK

Electronic monitoring (EM) of individuals has been used by the criminal justice system for the past thirty years, and in the UK, use is on the increase. Its use has been justified as an alternative to prison to reduce recidivism and allowing early release of prisoners, however, the evidence base for this remains mixed. In 2010, it was employed for the first time in a forensic psychiatry setting. A study investigating the effects of EM on leave episodes concluded that EM may improve the speed of patient progress and reduce the length of admission, leading to reduced costs and increased public safety. However, the intervention generated considerable controversy and sparked discussion about ethical concerns. Here, we consider specifically legal and human rights issues that emerge from use of EM in forensic healthcare settings, scrutinising its use in the context of the Mental Health Act and the Human Rights Act. We conclude that EM is legal and justifiable, providing it is used judiciously and with due consideration of concerns for the individual and the given context.

A review of the treatment options for clozapine-induced hypersalivation

Aims and Method

To develop and introduce an evidence-based drug treatment protocol for clozapine-induced hypersalivation, a review of published literature relating to clozapine-induced hypersalivation and its treatment was undertaken in March 2000. The databases searched were Medline, EMBASE and PsychLit, from 1966 to the present.

Results

This paper reviews the evidence of the benefit of using antimuscarinic agents, adrenergic antagonists and adrenergic agonists. There is alack of good-quality controlled-trials, with most papers reporting aseries of uncontrolled cases dependent on subjective measures of improvement reported by the patients. However, the published literature suggests a benefit for all of the drug categories reviewed. The most effective treatment may be acombination of terazosin and benzhexol.

Clinical Implications

Clozapine-induced hypersalivation is not only an embarrassing problem, but can be difficult to treat. An evidence-based prescribing protocol will encourage the use of those drugs found to be the most effective in treating this problem. It will also offer alternatives if acertain treatment is ineffective or intolerable.

Section 136 and the Police

Section 136 of the Mental Health Act 1983 is a controversial section. It authorises a police constable, often with no psychiatric training, to take a mentally disordered person from a public place to a place of safety, usually a hospital or a police station, so that he or she may be assessed by a doctor and a social worker within a 72 hour period. There have been several studies looking at this section from the point of view of psychiatrists, social workers, and other interested parties, in particular MIND. The aim of this study was to find out from the police whether or not problems arose during their dealings with people whom they had placed on section 136.

Can electronic monitoring (GPS 'tracking') enhance risk management in psychiatry?

Electronic monitoring has been used in criminal justice and some health settings for three decades. Technological interventions are becoming more common in psychiatry, but may be a cause for ethical concerns and controversy. We discuss electronic monitoring as an aid to security and public safety in a forensic setting.

Frontotemporal white-matter microstructural abnormalities in adolescents with conduct disorder: a diffusion tensor imaging study

BACKGROUND

Children with conduct disorder (CD) are at increased risk of developing antisocial personality disorder (ASPD) and psychopathy in adulthood. The biological basis for this is poorly understood. A preliminary diffusion tensor magnetic resonance imaging (DT-MRI) study of psychopathic antisocial adults reported significant differences from controls in the fractional anisotropy (FA) of the uncinate fasciculus (UF), a white-matter tract that connects the amygdala to the frontal lobe. However, it is unknown whether developmental abnormalities are present in the UF of younger individuals with CD.

METHOD

We used DT-MRI tractography to investigate, for the first time, the microstructural integrity of the UF in adolescents with CD, and age-related differences in this tract. We compared FA and perpendicular diffusivity of the UF in 27 adolescents with CD and 16 healthy controls (12 to 19 years old) who did not differ significantly in age, IQ or substance use history. To confirm that these findings were specific to the UF, the same measurements were extracted from two non-limbic control tracts. Participants in the CD group had a history of serious aggressive and violent behaviour, including robbery, burglary, grievous bodily harm and sexual assault.

RESULTS

Individuals with CD had a significantly increased FA (p = 0.006), and reduced perpendicular diffusivity (p = 0.002), in the left UF. Furthermore, there were significant age-related between-group differences in perpendicular diffusivity of the same tract (Z obs = 2.40, p = 0.01). Controls, but not those with CD, showed significant age-related maturation. There were no significant between-group differences in any measure within the control tracts.

CONCLUSIONS

Adolescents with CD have significant differences in the 'connectivity' and maturation of UF.

Violent behaviour in U.K. military personnel returning home after deployment

BACKGROUND

There is growing concern about an alleged rise in violent behaviour amongst military personnel returning from deployment to Iraq and Afghanistan. The aims of this study were to determine the prevalence of violence in a sample of U.K. military personnel following homecoming from deployment in Iraq and to examine the impact of deployment-related experiences, such as combat trauma, on violence, and the role of sociodemographics and pre-enlistment antisocial behaviour.

METHOD

This study used baseline data from a cohort study of a large randomly selected sample of U.K. Armed Forces personnel in service at the time of the Iraq war (2003). Regular personnel (n=4928) who had been deployed to Iraq were included. Data, collected by questionnaire, included information on deployment experiences, sociodemographic and military characteristics, pre-enlistment antisocial behaviour, post-deployment health outcomes and a self-report measure of physical violence in the weeks following return from deployment.

RESULTS

Prevalence of violence was 12.6%. This was strongly associated with pre-enlistment antisocial behaviour [adjusted odds ratio (aOR) 3.6, 95% confidence interval (CI) 2.9-4.4]. After controlling for pre-enlistment antisocial behaviour, sociodemographics and military factors, violence was still strongly associated with holding a combat role (aOR 2.0, 95% CI 1.6-2.5) and having experienced multiple traumatic events on deployment (aOR for four or more traumatic events 3.7, 95% CI 2.5-5.5). Violence on homecoming was also associated with mental health problems such as post-traumatic stress disorder (aOR 4.8, 95% CI 3.2-7.2) and alcohol misuse (aOR 3.1, 95% CI 2.5-3.9).

CONCLUSIONS

Experiences of combat and trauma during deployment were significantly associated with violent behaviour following homecoming in U.K. military personnel. Post-deployment mental health problems and alcohol misuse are also associated with increased violence.

A multi-site randomized controlled trial of a cognitive skills programme for male mentally disordered offenders: social-cognitive outcomes

BACKGROUND

Cognitive skills programmes have been associated with improvements on psychometric measures and reductions in antisocial behaviour in mentally disordered offenders (MDOs). However, to date there have been no randomized controlled trials (RCTs) of such programmes with this population. In the first RCT of a cognitive skills programme with MDOs we aimed to determine if participation in the Reasoning and Rehabilitation (R&R) programme was associated with improvements in social-cognitive skills and thinking styles.

METHOD

A total of 84 men with a primary diagnosis of psychotic disorder and a history of violence were recruited from medium-secure forensic units and allocated to receive R&R (n=44) or treatment as usual (TAU; n=40). At baseline and post-treatment interviews, participants completed questionnaires to assess social problem-solving, criminal attitudes, anger experience, blame externalizing and perspective-taking. Researchers were not blind to group status.

RESULTS

The R&R group demonstrated significant improvements on measures of social problem-solving relative to the TAU group, some of which were maintained at 12 months post-treatment. Only half of those allocated to receive R&R completed the full programme. In post-hoc analyses programme completers showed improvements in social problem-solving at the end of treatment and changes in criminal attitudes at 12 months post-treatment.

CONCLUSIONS

Among male MDOs, R&R participation was associated with improvements in social-cognitive skills, some of which were maintained for up to 12 months post-treatment. Our finding that programme completers do better may reflect pre-treatment patient characteristics. This study establishes that multi-site RCTs can be conducted in medium-secure forensic units.

Altered connections on the road to psychopathy

Psychopathy is strongly associated with serious criminal behaviour (for example, rape and murder) and recidivism. However, the biological basis of psychopathy remains poorly understood. Earlier studies suggested that dysfunction of the amygdala and/or orbitofrontal cortex (OFC) may underpin psychopathy. Nobody, however, has ever studied the white matter connections (such as the uncinate fasciculus (UF)) linking these structures in psychopaths. Therefore, we used in vivo diffusion tensor magnetic resonance imaging (DT-MRI) tractography to analyse the microstructural integrity of the UF in psychopaths (defined by a Psychopathy Checklist Revised (PCL-R) score of > or = 25) with convictions that included attempted murder, manslaughter, multiple rape with strangulation and false imprisonment. We report significantly reduced fractional anisotropy (FA) (P<0.003), an indirect measure of microstructural integrity, in the UF of psychopaths compared with age- and IQ-matched controls. We also found, within psychopaths, a correlation between measures of antisocial behaviour and anatomical differences in the UF. To confirm that these findings were specific to the limbic amygdala-OFC network, we also studied two 'non-limbic' control tracts connecting the posterior visual and auditory areas to the amygdala and the OFC, and found no significant between-group differences. Lastly, to determine that our findings in UF could not be totally explained by non-specific confounds, we carried out a post hoc comparison with a psychiatric control group with a past history of drug abuse and institutionalization. Our findings remained significant. Taken together, these results suggest that abnormalities in a specific amygdala-OFC limbic network underpin the neurobiological basis of psychopathy.

Emotional arousal in cocaine exposed toddlers: prediction of behavior problems

Prenatal cocaine exposure (PCE) may be associated with alterations in children's developing emotional arousal and regulation systems.

OBJECTIVE

We examined emotional responses to a frustrating task and subsequent behavior problems in 225 2 1/2 year olds (129 Prenatally Cocaine and Other Drug Exposed [PCE], 30 Non Cocaine but other drug Exposed [NCE], 66 Non Drug Exposed [NDE]).

METHOD

Children's behaviors in a frustrating toy wait task at age 2 1/2 were coded for emotional arousal and regulation behaviors.

RESULTS

Findings indicated a trend for PCE toddlers to show greater agitated emotional arousal than NCE and NDE toddlers. Further, PCE boys made more references to their caregivers in the task than NDE boys. Higher agitated arousal at age 2 1/2 years was related to greater decreases in externalizing behaviors through age 5 1/2 years.

CONCLUSION

Findings suggest a link between cocaine exposure and emotional arousal and regulation and highlight the need to understand complex relations between emotion and risk for later psychopathology in exposed youth.

Predictors of violent victimization amongst those with psychosis

OBJECTIVE

The aim of this study was to establish the prevalence and predictors of violent victimization amongst a community-dwelling sample of individuals with psychosis.

METHOD

The 2-year prevalence of self-reported violent victimization was estimated for a sample of 708 individuals with chronic psychosis living in the community in four urban UK centres. Baseline socio-demographic and clinical factors were examined as possible risk factors for victimization over the 2-year follow-up period.

RESULTS

The 2-year prevalence of violent victimization in the sample was 23%. Four factors were found to be independently predictive of victimization - history of victimization, less than daily family contact, young age at illness onset and the presence of co-morbid Cluster B personality disorder.

CONCLUSION

Those with psychotic illnesses are at elevated risk of being assaulted. Given the likely adverse health implications, clinicians should routinely enquire about victimization in their assessments of those with psychotic disorders particularly amongst those who are socially isolated, with a younger age of illness onset and in those with co-morbid personality disorder.

Do care patterns change over time in a newly established mental health service? A report from the UK700 trial

PURPOSE

Data on the process of mental health care is scant. Most studies focus on services at their inception when activity may be atypical and then usually present data only mean values for the reported variables over the whole study period. We aimed to test whether care delivery changes over time, and to describe any changes at the individual patient and team levels.

METHODS

Process data on 272 patients in three new intensive case management (ICM) teams were collected over 2 years. Interventions were prospectively recorded using clinician-derived categories. Changes over time are described at both patient and team level.

RESULTS

The number of contacts and the proportion of face-to-face activity were remarkably constant after the first month at the patient level. The proportion of 'psychiatric' interventions (main focus on medication or a specific 'mental health' intervention performed) increased greatly after the first 6 months. The care activity received by individual patients varied considerably. Overall, teams varied significantly in the extent to which their activity rates were sustained over time.

CONCLUSIONS

New ICM teams deliver highly individualised care with more marked differences in treatment patterns between patients in the same team than mean differences between teams. The early 'engagement' period is marked by a greater focus on social care. There is evidence of differences in sustainability of the services by site.

A comparison of statistical models in predicting violence in psychotic illness

BACKGROUND

The application of statistical modeling techniques, including classification and regression trees, in the prediction of violence has increasingly received attention.

METHODS

The predictive performance of logistic regression and classification tree methods in predicting violence was explored in a sample of patients with psychotic illness.

RESULTS

Of 2 logistic regression models, the forward stepwise method produced a simpler model than the full model, but the latter performed better. The performance of the classification tree appeared to be high before cross-validation, but reduced when cross-validated. The standard logistic model was the most robust model. A simplified tree with extra weight given to violent cases was a reasonable competitor and was simple to apply.

CONCLUSION

Although classification trees can be suitable for routine clinical practice, because of the simplicity of their decision-making processes, their robustness and therefore clinical utility was problematic in this sample. Further research is required to compare such models in large prospective epidemiologic studies of other psychiatric populations.

Aripiprazole in schizophrenia: consensus guidelines

Schizophrenia is a chronic disabling disease which in the majority of cases requires long-term treatment with antipsychotic medication. Before the development of atypical antipsychotics, treatment choice was restricted to conventional (or typical) antipsychotics, which are known to cause a range of side effects including extrapyramidal symptoms. Although atypical agents provide a favourable alternative (advocated by the National Institute of Clinical Excellence in the UK), they are associated with side effects. These differ between agents, but can include weight gain, sedation and hyperprolactinaemia. Aripiprazole is a newly available atypical antipsychotic for the treatment of schizophrenia. With the apparent imitations of currently available medications, aripiprazole provides clinicians with another treatment option. The purpose of these guidelines is to outline the consensus reached by the Schizophrenia Innovation Working Group on best practice in prescribing and appropriate use of aripiprazole in the UK.

Predicting violence in schizophrenia: a prospective study

BACKGROUND

People with schizophrenia are more violent than the general population, but this increased risk is attributable to the actions of a small subgroup. Identifying those at risk has become an essential part of clinical practice.

AIMS

To estimate the risk factors for assault in patients with schizophrenia.

METHODS

Two hundred seventy-one patients with schizophrenia were interviewed using an extensive battery of instruments. Assault was measured from multiple data sources over the next 2 years and criminal records were obtained. Multiple sociodemographic and clinical variables measured at baseline were examined as possible predictors of assault during follow-up.

RESULTS

Sixty-nine (25%) patients committed assault during the 2-year follow-up. The model that best predicted assault included a history of recent assault (OR 2.33, 95% CI 1.17-4.61), a previous violent conviction (OR 2.02, 95% CI 1.04-3.87), having received special education (OR 2.76, 95% CI 1.22-6.26) and alcohol abuse (OR 3.55, 95% CI 1.24-10.2).

CONCLUSIONS

Previously established risk factors including a history of violence and alcohol abuse are replicated in this study. Although low premorbid IQ did not predict violence, a need for special education did.

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.

Violence and schizophrenia: examining the evidence

BACKGROUND

It is now accepted that people with schizophrenia are significantly more likely to be violent than other members of the general population. A less acknowledged fact is that the proportion of societal violence attributable to schizophrenia is small.

AIMS

To critically examine the epidemiological evidence for the association between violence and schizophrenia and estimate the impact of this association on society.

METHOD

A selective review of the key literature on the epidemiology of violence and schizophrenia. Population-attributable risks for violence in schizophrenia are calculated from population-based studies.

RESULTS

Most studies confirm the association between violence and schizophrenia. Recent good evidence supports a small but independent association. Comorbid substance abuse considerably increases this risk. The proportion of violent crime in society attributable to schizophrenia consistently falls below 10%.

CONCLUSIONS

Less focus on the relative risk and more on the absolute risk of violence posed to society by people with schizophrenia would serve to reduce the associated stigma. Strategies aimed at reducing this small risk require further attention, in particular treatment for substance misuse.

Reducing violence in severe mental illness: randomised controlled trial of intensive case management compared with standard care

OBJECTIVES

To establish whether intensive case management reduces violence in patients with psychosis in comparison with standard case management.

DESIGN

Randomised controlled trial with two year follow up.

SETTING

Four inner city community mental health services.

PARTICIPANTS

708 patients with established psychotic illness allocated at random to intervention (353) or control (355) group.

INTERVENTION

Intensive case management (caseload 10-15 per case manager) for two years compared with standard case management (30-35 per case manager).

MAIN OUTCOME MEASURE

Physical assault over two years measured by interviews with patients and case managers and examination of case notes.

RESULTS

No significant reduction in violence was found in the intensive case management group compared with the control group (22.7% v 21.9%, P=0.86).

CONCLUSIONS

Intensive case management does not reduce the prevalence of violence in psychotic patients in comparison with standard care.

Relatives of patients with severe psychotic illness: factors that influence appraisal of caregiving and psychological distress

BACKGROUND

Research shows considerable variability in the effect on relatives of patients' mental illness but the determinants of relatives' experience remain unclear. We investigated the influence of demographic, social and clinical characteristics on relatives' experience when conceptualised using a stress-appraisal-coping paradigm.

METHODS

Our sample was drawn from relatives of patients recruited to the UK700 case management study (n = 154). Demographic, social and clinical data were collected from patients, and relatives completed the Experience of Caregiving Inventory and the General Health Questionnaire. We predicted that patients' symptomatology in particular would influence relatives' experience, and that relatives who appraised caregiving more negatively and less positively would experience greater psychological distress.

RESULTS

Linear regression analyses revealed that relatives' appraisal was not predicted by patients' symptomatology. Instead, relatives appraised caregiving more negatively if the patient was unemployed or younger, and less positively if the patient had been ill for longer or had poorer social functioning. Little of the variance in appraisal was explained by these variables, however. Consistent with the stress-coping model, relatives' negative appraisal was a strong predictor of psychological distress and accounted for a substantial proportion of its variance. Positive appraisal did not predict psychological distress, however. None of the demographic, social or clinical characteristics tested had any significant effect on relatives' psychological distress once appraisal was adjusted for. There was an unexpected positive correlation between the two appraisal scales, with relatives who appraised caregiving more negatively also appraising it more positively.

CONCLUSIONS

Our results support a stress-coping model of caregiving but further research is required to determine more influential predictors of relatives' appraisal. Our findings indicate that interventions aimed at patients' social functioning and relatives' negative appraisal of caregiving may assist in reducing relatives' psychological distress.

Quality of life outcome in a randomized controlled trial of case management

BACKGROUND

This paper presents the quality of life (QOL) outcome results from the UK700 randomised controlled trial of case management.

METHOD

A total of 708 patients with severe mental illness were randomly assigned to intensive and standard forms of case management in four sites in the UK. QOL was assessed using the Lancashire Quality of Life Profile, which provides a self-reported objective and subjective appraisal of eight life domains (finances, work, leisure, family, social relations, living situation, safety and health). The outcome after 2 years was examined using univariate and multivariate analyses.

RESULTS

Significant improvements in QOL over the 2 years were observed. The QOL outcome did not differ significantly by case management treatment conditions or by diagnosis. A better outcome was associated with improvements in depression and with the location (site) of treatment. In one site there were significant improvements in all eight domains and overall QOL, with moderate or better effect sizes (> 0.4) in three domains and overall QOL.

CONCLUSIONS

Depression should be assessed when subjective QOL measures are used. Better means for describing service organisations and the context/place in which they operate should be developed in order to explain more of the variance in QOL outcomes.

Relatives of patients with severe psychotic disorders: factors that influence contact frequency. Report from the UK700 trial

BACKGROUND

The isolation experienced by many patients with severe psychotic disorders is generally assumed to be due to their social withdrawal. An alternative possibility is that relatives avoid frequent contact with patients because they find the situation distressing.

AIMS

To examine the predictors of frequent patient-relative contact, in particular the role of relatives' experience.

METHOD

UK700 trial data were used to determine baseline predictors of frequent contact and establish whether relatives' experience at baseline predicted continued frequent contact 2 years later.

RESULTS

Neither characteristics associated in the literature with relatives' 'burden' nor relatives' experience predicted patient-relative contact frequency. Instead, the predictors were mainly demographic.

CONCLUSIONS

Many relatives experience considerable distress, but the evidence does not suggest that they avoid frequent contact with the patient as a consequence.

Effects of case-load size on the process of care of patients with severe psychotic illness. Report from the UK700 trial

BACKGROUND

Studies of intensive case management (ICM) for patients with psychotic illnesses have produced conflicting results in terms of outcome. Negative results have sometimes been attributed to a failure to deliver differing patterns of care.

AIMS

To test whether the actual care delivered in a randomised clinical trial of ICM v. standard case management (the UK700 trial) differed significantly.

METHOD

Data on 545 patients' care were collected over 2 years. All patient contacts and all other patient-centred interventions (e.g. telephone calls, carer contacts) of over 15 minutes were prospectively recorded. Rates and distributions of these interventions were compared.

RESULTS

Contact frequency was more than doubled in the ICM group. There were proportionately more failed contacts and carer contacts but there was no difference in the average length of individual contacts or the proportion of contacts in the patients' homes.

CONCLUSIONS

The failure to demonstrate outcome differences in the UK700 study is not due to a failure to vary the treatment process. UK standard care contains many of the characteristics of assertive outreach services and differences in outcome may require that greater attention be paid to delivering evidence-based interventions.

Enfreaking war-injured bodies: fallen soldiers in propaganda and American literature of the 1920s

With P. T. Barnum's purchase of the American museum in 1840, freak shows became an organized and profitable institution that systematically used juxtaposition, innovative advertising, and questions of truth and humbug to entice audiences. Along with “scientifically” sanctioned pamphlets and cartes de visite, exhibits such as wild savages from around the world, human-animal hybrids, hermaphrodites, and armless and legless wonders played with the boundaries between self and other. Audiences could gaze safely without compunction about the displayed body as long as these distinctions were maintained within the confines of the show. But as social anxieties about difference intensified in the first few decades of the 20th century, a greater need to solidify the boundaries between black and white, male and female, and abled and disabled made this type of entertainment more disturbing and, at times, even dangerous. These concerns marked the beginning of the end for freak shows. By the 1920s, their popularity was not only threatened by changing attitudes in medical science and the rise of the film industry, but also by the aftermath of World War I.

Life events, ethnicity and perceptions of discrimination in patients with severe mental illness

BACKGROUND

Whilst it is commonly believed that black and ethnic minority (B&EM) people living in the UK experience social disadvantage compared with the white British (WB) population, no study has specifically addressed this issue in patients with severe mental illness. We sought to test the hypothesis that B&EM patients experience more negative life events than their WB counterparts, and to examine the extent to which they attribute these events to discrimination.

METHOD

Thirty-four WB, 78 African Caribbean (AC) and 35 other ethnic minority patients with psychotic illnesses, defined using Research Diagnostic Criteria, were asked to complete a Racial Life Event Questionnaire examining life events and perceptions of discrimination at baseline and 12 and 24 months later.

RESULTS

African Caribbean patients experienced more 'Financial' life events across the study period, otherwise there were no significant differences between patient groups in number of life events experienced. The B&EM group collectively (n = 113), however, were significantly more likely than the WB group (n = 34) to attribute 'Assault', and 'Legal' life events to discrimination. The AC patient group were significantly more likely than the other two ethnic groups to attribute the 'Financial' and 'Health' life events they experienced to discrimination. The B&EM group was also significantly more likely, and particularly the AC patient group, to report that members of their own ethnic group are adversely affected by discrimination. Further analyses showed skin colour rather than ethnicity or nationality to be the major contributing factor to perception of discrimination; thus, the Irish (n = 11) had similar scores to the WB while Africans (n = 16) scored like the ACs.

CONCLUSION

Our study shows that B&EM patients do not experience significantly more life events than WB patients; however, their perception of these events is clearly different, and significantly more often attributed to racism. It is reasonable to suppose that patients may be disinclined to utilise services they believe to be prejudiced against them on the basis of their skin colour, and service providers need to be aware of this in order to create health care services that B&EM patients feel confident to use.

Intensive versus standard case management for severe psychotic illness: a randomised trial. UK 700 Group

BACKGROUND

Case management has increasingly been the recommended approach to care for severely mentally ill patients since the number of psychiatric beds has decreased. Despite equivocal results, in the UK and Europe, this approach is becoming accepted policy. We assessed the effect of smaller case loads.

METHODS

We randomly assigned 708 psychotic patients in four centres standard case management (355 patients, case load 30-35 per case manager) or intensive case management (353 patients, case load 10-15 per case manager). We measured clinical symptoms and social functioning at baseline, 1 year, and 2 years. The impact of treatment on hospital use was assessed at 2 years by subgroup analyses for Afro-Caribbean and for severely socially disabled patients. Analysis was by intention to treat.

FINDINGS

There was no significant decline in overall hospital use among intensive-case-management patients (mean 73.5 vs 73.1 days in those who received standard care [SD 0.4, 95% CI -17.4 to 18.1]), nor were there any significant gains in clinical or social functioning. There was no evidence of differential effect in Afro-Caribbean patients or the most socially disabled patients.

INTERPRETATION

In well-coordinated mental-health services, a decline in case load alone does not improve outcome for these patients. Mental-health planners may need to pay more attention to the content of treatment rather than changes in service organisation.

Tardive dyskinesia: who is at risk?

Tardive dyskinesia (TD) has been associated with female gender, affective symptoms and good outcome, but also with negative symptoms, cognitive deterioration and deteriorating illness course. Furthermore, antipsychotic medication is thought to be an important risk factor, yet abnormal movements also occur in patients who have never received such medication. We followed 166 subjects with recent onset of psychotic illness and brief previous exposure to antipsychotic medication. Information on 17 previously reported risk factors was available for 125 patients at baseline and, for factors that vary over time, again at follow-up 4 years later (median, 50 months; interquartile range, 29-70). Movement disorder was assessed at follow-up using the Abnormal Involuntary Movement Scale (AIMS). Six noninteracting variables were independently associated with the 4-year risk of TD: male sex (OR, 2.5; 95% CI, 1.1-5.0), age (OR over quartiles at baseline, 1.6; 95% CI, 1.1-2.2), lack of insight at baseline (OR over four categories, 2.0; 95% CI, 1.2-3.2), time on antipsychotics during the follow-up period (OR over quartiles, 2.3; 95% CI, 1.5-3.4), an increase in negative symptoms during the follow-up period (OR over quartiles, 1.7; 95% CI, 1.2-2.5), and alcohol/drug misuse at follow-up (OR, 3.0; 95% CI, 1.3-7.4). The presence of individual risk factors was found to be of little use as a screening test for subsequent clinically relevant TD. Given the absence of a risk factor, however, the probability that an individual would not develop TD was high. These results suggest that two discrete effects may operate to increase the risk of TD, namely an exogenous factor (medication, drugs), and an illness-related factor, the highest risk being conferred by deteriorating illness course in male patients.

Coping strategies and psychiatric morbidity in women attending breast assessment clinics

This study examined the role of coping strategies and personality characteristics in mediating psychiatric morbidity in subjects facing possibly serious breast disease. Participating were 121 women aged 20 to 65 undergoing breast fine needle biopsy for a suspicious lesion on mammography. All subjects received psychosocial assessments including the 12-item General Health Questionnaire (GHQ-12), the Eysenck Personality Inventory (EPI) and the Coping Strategies Inventory. The results show that neuroticism was the only EPI subscore significantly correlated with GHQ-12 score. A habitual method of coping with adversity known as 'engagement' has a negative correlation with GHQ-12 score; that is, patients who actively confront their illness and the uncertainty that surrounds it show better psychological health. Stepwise multiple regression reveals that neuroticism and an engagement coping strategy are the most significant predictors towards GHQ-12 score prior to the diagnosis of breast cancer.

Adverse life events and breast cancer: case-control study

OBJECTIVE

To investigate the strength of association between past life events and the development of breast cancer.

DESIGN

Case-control study. A standardised life events interview and rating was administered before a definitive diagnosis.

SETTING

Breast Cancer Screening Assessment Unit and surgical outpatient clinics at King's College Hospital, London.

SUBJECTS

119 consecutive women aged 20-70 who were referred for biopsy of a suspicious breast lesion.

MAIN OUTCOME MEASURES

Odds ratio of the risk of developing breast cancer after life events in the preceding five years after adjustment for confounders.

RESULTS

41 women were diagnosed as having malignant disease while the remainder had benign conditions. Severe life events increased the risk of breast cancer. The crude odds ratio was 3.2 (95% confidence interval 1.35 to 7.6). After adjustment for age and the menopause and other potential confounders this rose to 11.6 (3.1 to 43.7). Multiple logistic regression analysis showed that all severe events and coping with the stress of adverse events by confronting them and focusing on the problems significantly predicted a diagnosis of breast cancer. Non-severe life events and long term difficulties had no significant association.

CONCLUSION

These findings suggest an aetiological association between life stress and breast cancer.

Psychosis with good prognosis in Afro-Caribbean people now living in the United Kingdom

OBJECTIVES

To compare the course and outcome of psychotic illness in a group of Afro-Caribbean patients resident in the United Kingdom and a group of white British patients.

DESIGN

Cohort study of consecutive admissions followed up for four years.

SUBJECTS

113 patients with psychotic illness of recent onset admitted to two south London hospitals.

MAIN OUTCOME MEASURES

Course of illness, history of self harm, social disability, treatment received, and hospital use adjusted for socioeconomic origin.

RESULTS

The Afro-Caribbean group spent more time in a recovered state during the follow up period (adjusted odds ratio 5.0; 95% confidence interval 1.7 to 14.5), were less likely to have had a continuous illness (0.3; 0.1 to 0.8), were less at risk of self harm (0.2; 0.1 to 0.8), and were less likely to have been prescribed antidepressant treatment (0.3; 0.1 to 0.9). There were no differences in hospital use, but the Afro-Caribbean group had more involuntary admissions (8.9; 2.1 to 35.6) and more imprisonments over the follow up period (9.2; 1.6 to 52.3).

CONCLUSIONS

Afro-Caribbean patients in the United Kingdom have a better outcome after psychiatric illness than do white people. The combination of high incidence and more benign course of illness of psychotic illness in this group may be due, at least in part, to a greater exposure to precipitants in the social environment.

Insight and psychotic illness. Cross-sectional and longitudinal associations

BACKGROUND

Insight has recently re-emerged as an important aspect of psychopathology amenable to empirical study. We sought to examine the relationship between various aspects of insight into illness and clinical, sociodemographic and neuropsychological variables.

METHOD

From an inner-London catchment area population, 150 in-patients with recent onset of psychosis were assessed on a variety of measures, including the Present State Examination (PSE). Subjects were followed up for a mean of four years and reassessed.

RESULTS

High IQ was associated with better insight as rated on the PSE, while gender, ethnicity and a diagnosis of schizophrenia appeared to be unrelated. At follow-up, similar associations were found, as well as correlations with attitudes to treatment and a more elaborate measure of insight. Cerebral ventricular enlargement and tests of frontal lobe function did not correlate with insight, but there was a curious, strong association with left-handedness at both assessment points. Initial insight correlated significantly but weakly with insight at follow-up.

CONCLUSIONS

The assessment of insight in psychosis has concurrent validity and is a distinct aspect of psychotic phenomenology. It may, in part, have a neuropsychological basis.

Psychiatric outcome in alcoholic liver transplant patients

We investigated drinking behaviour and psychiatric outcome of patients with alcoholic liver disease after liver transplantation, to help assess the advisability of the procedure in these patients. English-speaking patients (n = 20) transplanted for alcoholic liver disease and informants, and patients transplanted for non-alcoholic liver disease (n = 54), were assessed by semi-structured interviews and standardized questionnaires 1-6 years following transplantation. All alcoholics were abstinent for several months after transplantation, but only one patient remained totally abstinent. Sixteen of the 20 alcoholics later returned to regular drinking; the mean daily alcohol consumption was 3.5 units. Forty percent of the group were drinking above the recommended safe levels for the general population and over 50% were 'binge' drinking intermittently. The alcoholic liver transplant patients did not have higher levels of psychiatric or physical morbidity than controls. Patients with alcoholic liver disease return to drinking after a period of abstinence following liver transplantation, although at lower levels than before. Their vulnerability to alcohol abuse is not explained by higher levels of physical or psychiatric morbidity.

Impulsivity and eating disorders

Sixty-seven patients with bulimia nervosa and 29 patients with anorexia nervosa completed the Impulsiveness Questionnaire and questionnaires detailing severity of eating disorder. Bulimic patients had higher impulsivity scores than anorexic patients. Bulimics with high impulsivity scores did not have more severe eating disorders than low scorers. When 39 bulimics and 25 anorexics were interviewed about other impulsive behaviour, 51% of bulimics and 28% of anorexics reported at least one other impulsive behaviour. Patients with so-called 'multi-impulsive' bulimia reported more severe eating disturbance, but this was not reflected on more reliable measures of symptoms. Thirty-nine bulimics entered an eight-week treatment trial and their progress was assessed at eight weeks, 16 weeks and one year. 'Non-impulsive' bulimics had a more rapid response than 'impulsives' during treatment, but there was no difference at follow-up. There was no evidence of an association between high impulsivity trait scores and poor treatment response. It is concluded that impulsivity may shape the expression of eating disorders, but that 'multi-impulsives' do not constitute a categorically distinct subgroup of bulimics.
