Screening and referral for brief intervention of alcohol-misusing patients in an emergency department: a pragmatic randomised controlled trial.

BACKGROUND Alcohol misuse is highly prevalent among people attending emergency departments, but the effect of intervention by staff working in these departments is unclear. We investigated the effect of screening and referral of patients found to be misusing alcohol while attending an emergency department. METHODS We undertook a single-blind pragmatic randomised controlled trial. Patients received either an information leaflet or an information leaflet plus an appointment with an alcohol health worker. Outcome data were collected by patient interview and examination of hospital records at 6 and 12 months. FINDINGS 599 patients were randomised over a 12-month period. At 6 months, those referred to an alcohol health worker were consuming a mean of 59.7 units of alcohol per week compared with 83.1 units in the control group (t -2.4, p=0.02). At 12 months those referred were drinking 57.2 units per week compared with 70.8 in controls (t -1.7, p=0.09). Those referred to the alcohol health worker had a mean of 0.5 fewer visits to the emergency department over the following 12 months (1.2 compared with 1.7, t -2.0, p=0.046). Differences in quality of life were not found. INTERPRETATION Opportunistic identification and referral for alcohol misuse in an emergency department is feasible, associated with lower levels of alcohol consumption over the following 6 months, and reduces reattendance at the department. Short-term reductions in alcohol consumption associated with referral for brief intervention for alcohol misuse benefit patients and reduce demand for accident and emergency department services.

Classification, assessment, prevalence, and effect of personality disorder

Personality disorders are common and ubiquitous in all medical settings, so every medical practitioner will encounter them frequently. People with personality disorder have problems in interpersonal relationships but often attribute them wrongly to others. No clear threshold exists between types and degrees of personality dysfunction and its pathology is best classified by a single dimension, ranging from normal personality at one extreme through to severe personality disorder at the other. The description of personality disorders has been complicated over the years by undue adherence to overlapping and unvalidated categories that represent specific characteristics rather than the core components of personality disorder. Many people with personality disorder remain undetected in clinical practice and might be given treatments that are ineffective or harmful as a result. Comorbidity with other mental disorders is common, and the presence of personality disorder often has a negative effect on course and treatment outcome. Personality disorder is also associated with premature mortality and suicide, and needs to be identified more often in clinical practice than it is at present.

Group art therapy as an adjunctive treatment for people with schizophrenia: multicentre pragmatic randomised trial

Objectives To evaluate the clinical effectiveness of group art therapy for people with schizophrenia and to test whether any benefits exceed those of an active control treatment. Design Three arm, rater blinded, pragmatic, randomised controlled trial. Setting Secondary care services across 15 sites in the United Kingdom. Participants 417 people aged 18 or over, who had a diagnosis of schizophrenia and provided written informed consent to take part in the study. Interventions Participants, stratified by site, were randomised to 12 months of weekly group art therapy plus standard care, 12 months of weekly activity groups plus standard care, or standard care alone. Art therapy and activity groups had up to eight members and lasted for 90 minutes. In art therapy, members were given access to a range of art materials and encouraged to use these to express themselves freely. Members of activity groups were offered various activities that did not involve use of art or craft materials and were encouraged to collectively select those they wanted to pursue. Main outcome measures The primary outcomes were global functioning, measured using the global assessment of functioning scale, and mental health symptoms, measured using the positive and negative syndrome scale, 24 months after randomisation. Main secondary outcomes were levels of group attendance, social functioning, and satisfaction with care at 12 and 24 months. Results 417 participants were assigned to either art therapy (n=140), activity groups (n=140), or standard care alone (n=137). Primary outcomes between the three study arms did not differ. The adjusted mean difference between art therapy and standard care at 24 months on the global assessment of functioning scale was −0.9 (95% confidence interval −3.8 to 2.1), and on the positive and negative syndrome scale was 0.7 (−3.1 to 4.6). Secondary outcomes did not differ between those referred to art therapy or those referred to standard care at 12 or 24 months. Conclusions Referring people with established schizophrenia to group art therapy as delivered in this trial did not improve global functioning, mental health, or other health related outcomes.

Patients or partners? Case studies of user involvement in the planning and delivery of adult mental health services in London

User or patient involvement (UI) in the planning and delivery of health services is an aspiration of many industrialized economies, and has been promoted by United Kingdom (UK) governments for over two decades. This paper reports the findings of qualitative case studies of UI in two mental health provider Trusts in London. Semi-structured interviews were conducted with a variety of stakeholders, including Trust staff at all levels and user group members, to compare the expectations of diverse stakeholders and the extent to which these were achieved. We found that UI remained in the gift of provider managers: providers retained control over decision making, and expected users to address Trust agendas and conform to Trust management practices. Users wanted to achieve concrete changes to policies and services, but had broader aspirations to improve the status and condition of people with mental health problems. Suggestions are made about the direction of future strategies to improve UI.

User involvement in the planning and delivery of mental health services: a cross-sectional survey of service users and providers

Objective:  To identify methods for involving service users in the planning and delivery of psychiatric services and factors which may assist and impede this process.

Qualitative research in psychiatry.

This paper is an overview of qualitative research and its application to psychiatry. It is introductory and attempts to describe both the aims of qualitative research and its underlying philosophical basis. We describe the practice and process of qualitative research and follow this with an overview of the 3 main methods of inquiry: interviews, focus groups, and participant observation. Throughout the paper, we offer examples of cases where qualitative research has illuminated, or has the potential to illuminate, important questions in psychiatric research. We describe methods of sampling and follow with an overview of qualitative analysis, appropriate checks on rigour, and the presentation of qualitative results. The paper concludes by arguing that qualitative methods may be an increasingly appropriate methodology to answer some of the demanding research questions being posed in 21st century psychiatry.

Providing continuity of care for people with severe mental illness- a narrative review.

Abstract.Background:Service users and providers have stated that delivering continuity of care to people with severe mental illness should be a service priority. We reviewed literature on continuity of care for people with severe mental illness (SMI) in order to identify factors that promote and impede this process.Method:A systematic search of electronic databases, sources of grey literature and contact with experts in the field. Two reviewers independently rated all papers for possible inclusion. Data extracted from papers formed the basis of a narrative review.Results:We identified 435 papers on continuity of care, of which 60 addressed the study aims. Most did not define continuity of care. Available evidence suggests that assertive community treatment, case management, community mental health teams and crisis intervention reduce the likelihood of patients dropping out of contact with services.Conclusions:Evidence on which to base services that enhance continuity of care for people with SMI is limited because previous research has often failed to define continuity of care or consider the patient’s perspective.

Clinical and cost-effectiveness of cognitive behaviour therapy for health anxiety in medical patients: a multicentre randomised controlled trial

BACKGROUND Health anxiety has been treated by therapists expert in cognitive behaviour therapy with some specific benefit in some patients referred to psychological services. Those in hospital care have been less often investigated. Following a pilot trial suggesting efficacy we carried out a randomised study in hospital medical clinics. METHODS We undertook a multicentre, randomised trial on health anxious patients attending cardiac, endocrine, gastroenterological, neurological, and respiratory medicine clinics in secondary care. We included those aged 16-75 years, who satisfied the criteria for excessive health anxiety, and were resident in the area covered by the hospital, were not under investigation for new pathology or too medically unwell to take part. We used a computer-generated random scheme to allocate eligible medical patients to an active treatment group of five-to-ten sessions of adapted cognitive behaviour therapy (CBT-HA group) delivered by hospital-based therapists or to standard care in the clinics. The primary outcome was change in health anxiety symptoms measured by the Health Anxiety Inventory at 1 year and the main secondary hypothesis was equivalence of total health and social care costs over 2 years, with an equivalence margin of £150. Analysis was by intention to treat. The study is registered with controlled-trials.com, ISRCTN14565822. FINDINGS Of 28,991 patients screened, 444 were randomly assigned to receive either adapted cognitive behaviour therapy (CBT-HA group, 219 participants) or standard care (standard care group, 225), with 205 participants in the CBT-HA group and 212 in the standard care group included in the analyses of the primary endpoints. At 1 year, improvement in health anxiety in the patients in the CBT-HA group was 2·98 points greater than in those in the standard care group (95% CI 1·64-4·33, p<0·0001), and twice as many patients receiving cognitive behaviour therapy achieved normal levels of health anxiety compared with those in the control group (13·9% vs 7·3%; odds ratio 2·15, 95% CI 1·09-4·23, p=0·0273). Similar differences were observed at 6 months and 2 years, and there were concomitant reductions in generalised anxiety and, to a lesser extent, depression. Of nine deaths, six were in the control group; all were due to pre-existing illness. Social functioning or health-related quality of life did not differ significantly between groups. Equivalence in total 2-year costs was not achieved, but the difference was not significant (adjusted mean difference £156, 95% CI -1446 to 1758, p=0·848). INTERPRETATION This form of adapted cognitive behaviour therapy for health anxiety led to sustained symptomatic benefit over 2 years, with no significant effect on total costs. It deserves wider application in medical care. FUNDING National Institute for Health Research Health Technology Assessment Programme.

Classifying personality disorder according to severity.

Current systems for classifying personality disorder according to specific categories are unsatisfactory because they do not take account of wide variations in levels of personality disturbance and associated impairment. We review previous attempts to classify personality disorder according to severity and place these findings in the context of work exploring the severity of other mental disorders. On the basis of these findings, we propose a new system for classifying personality-related problems based on severity defined by the extent of personality disturbance, the level of social dysfunctioning, and the impact of the disorder for individuals and society. We recognize that studies using these definitions will need piloting and testing in field trials, but believe that this simplified approach to classifying personality disorder would encourage greater use by clinicians and assist those involved in planning services for people with personality disorder.

Cognitive behaviour therapy for violent men with antisocial personality disorder in the community: an exploratory randomized controlled trial

BACKGROUND Little information exists on treatment effectiveness in antisocial personality disorder (ASPD). We investigated the feasibility and effectiveness of carrying out a randomized controlled trial of cognitive behaviour therapy (CBT) in men with ASPD who were aggressive. METHOD This was an exploratory two-centre, randomized controlled trial in a community setting. Fifty-two adult men with a diagnosis of ASPD, with acts of aggression in the 6 months prior to the study, were randomized to either treatment as usual (TAU) plus CBT, or usual treatment alone. Change over 12 months of follow-up was assessed in the occurrence of any act of aggression and also in terms of alcohol misuse, mental state, beliefs and social functioning. RESULTS The follow-up rate was 79%. At 12 months, both groups reported a decrease in the occurrence of any acts of verbal or physical aggression. Trends in the data, in favour of CBT, were noted for problematic drinking, social functioning and beliefs about others. CONCLUSIONS CBT did not improve outcomes more than usual treatment for men with ASPD who are aggressive and living in the community in this exploratory study. However, the data suggest that a larger study is required to fully assess the effectiveness of CBT in reducing aggression, alcohol misuse and improving social functioning and view of others. It is feasible to carry out a rigorous randomized controlled trial in this group.
