Benchmarking has been advocated by the Department of Health as a tool of clinical governance. The essence of benchmarking is learning from the best practice of others. Its ability to compare services and outcomes of care can facilitate change, ensuring quality control and continuous service improvement. The concept is in its infancy in the National Health Service despite its exceptionally rapid growth in business organisations over the past 25 years. Many of the characteristics that make the process so valuable in business are equally relevant in healthcare. This article reviews the history of benchmarking and describes its application in mental health services for improving patient care. It includes an analysis of the centrality of the benchmarking doctrine to the core principles of clinical governance and reflects on the assets health services possess to facilitate benchmarking. It concentrates on the principles of setting up a team and uses a case example to highlight the organisational and clinical effect that a benchmarking project could have.

This article is aimed at psychotherapists and health practitioners who have not reflected on the role of race, culture and ethnicity in the provision of psychological treatments. We highlight the key issues of importance in engagement, assessment and ongoing therapy, supporting practitioners to reach a stage of pre-competency. Competency will be achieved with additional training, supervision and innovation.

Neuroimaging has been used in clinical practice for over 30 years, but it is still perceived as rarely offering the psychiatrist much help in direct patient management. As newer imaging modalities are introduced (from computed tomography and positron and single photon emission tomography to magnetic and functional magnetic resonance imaging), the promise of imminent clinical utility is reawakened, only to fade as the innovation is shown to be another, albeit useful, research tool. The aim of this article is to update readers on some recent advances that are starting to align the research and clinical functions of neuroimaging. As imaging becomes more accessible and affordable there is real promise that both clinicians and patients will begin to benefit more directly.

The epidemiology and management of schizophrenia have been well studied over the past few decades. In the UK, key findings that have emerged time and again are the excess prevalence and incidence rates of schizophrenia among people of African–Caribbean origin. The reasons for this excess and the implications of this finding are many. The findings may reflect a true excess or a methodological artefact related to errors in the estimation of numerator and denominator data. The findings have been increasingly accepted as better designed studies have emerged, but these still do not fully address concerns about the nature of schizophrenia in other cultural groups and in societies in which industrialisation and economic productivity of the individual are not considered to be as crucial for an individual's sense of belonging in a community.

What prior assumptions might a psychiatrist bring into the room when the patient is an asylum-seeker? First, as a member of the public he or she is likely to have a view on asylum-seeking as a sociological phenomenon – up to 5 million have sought asylum in Western Europe in the past decade – and on how ‘deserving’ the average case is. After all, two adversarially opposed constructions of asylum-seeking have predominated. Governments, and the conservative social sectors, have stressed the prevalence of ‘bogus' applications by people who are essentially economic migrants, portraying them as wily, determined and tough rather than as having suffered. On the other side are the agencies and interests who support asylum-seekers, and the liberal and radical social sectors. They portray asylum-seekers as people who had no choice but to run from their countries, innocent of any thought but to escape further persecution and the risk of death. This portrayal invokes the image of suffering and vulnerability rather than resilience and agency. The reality is the muddied, uneven terrain that lies between these two entrenched positions. Many asylum-seekers do not have stories that easily fit the definition of a political refugee in the 1951 United Nations Convention. Even those with the clearest-cut cases – such as those with a credible history of torture – usually cannot prove it; few are vulnerable in any medically attestable sense and, however much they have suffered, they continue to make choices and actively engage with their situations. All asylum-seekers are looking for a better life for themselves and their children.

Previous studies have demonstrated that smartphones are useful tools in everyday, evidence-based medical practice. This article gives an overview of the current use in psychiatry of smartphone apps aimed at patients and the general public, highlighting associated benefits and disadvantages. It also outlines how practising psychiatrists could embrace such technologies at an individual, organisational and national level.

With new developments in image generation and transmission, researchers have studied the feasibility of using comunications technology for remote diagnosis and care delivery. The term ‘telepsychiatry’ has been used to describe the application of telemedicine and telecare to mental health. This article reviews the development of telepsychiatry and key research findings. Results suggest that service users are more comfortable with mediated services than are professsonals. Most work has been done in areas of low population density, where accessibility to conventional services is limited by economics and geography. In urban settings, with distributed community services, telepsychiatry can improve communication between primary and secondary sectors and within secondary services.

Treatment of illicit drug dependence typically involves a combination of pharmacotherapy and psychosocial interventions. Efficacy research supports methadone maintenance in opiate dependence. There is less evidence to support buprenorphine (an opiate receptor partial agonist), lofexidine (an α2-adrenoreceptor agonist) and naltrexone (an opiate receptor antagonist). Evidence for the effectiveness of detoxification, which one of the most widely used treatments, is poor. Of the psychosocial interventions, reasonable evidence exists for the effectiveness of motivational interviewing. Other psychosocial treatments have rarely been compared with no or minimal contact conditions in randomised trials, and their reported effectiveness is often weak. Residential treatments are not demonstrably more effective than community programmes.

Anxiety has reported prevalence rates between 38 and 72% among people with dementia. It has a negative impact on cognitive impairment and is associated with agitation and poor quality of life. The presence of excessive anxiety can be difficult to establish in people with dementia, especially when expressive or receptive speech is impaired. Unfortunately, there is a lack of research on the treatment of anxiety in dementia, and also on the wider issue of the management of anxiety disorders in old age. We explore the prevalence, presentation and diagnosis of anxiety in dementia and discuss the therapeutic options available.

This article reviews the literature on advance statements, including current mental health law and guidance in England and Wales, ethical and practical advantages, disadvantages and barriers to implementation. The idea of planning psychiatric treatment for a time when mental capacity may be impaired is not new. Yet there has been a renewed interest following the introduction of the Mental Capacity Act's 2005 provision of legally binding advance decisions to refuse treatment. In addition to information on treatment refusals, advance statements provide information on treatment preferences and personal care instructions which, although not legally binding, should inform treatment decisions. Advance statements are not yet widely used, but existing limited evidence suggests that they could reduce coercion and improve service users' satisfaction with treatment.

Attention-deficit hyperactivity disorder (ADHD) is a persistent, pervasive disorder characterised by symptoms of inattention, impulsivity and hyperactivity. Although traditionally considered a disorder of childhood, symptoms and associated impairments persist into adulthood for a significant proportion of individuals. Untreated ADHD can have a number of adverse effects for both the individual and wider society. Despite this, ADHD in adults is often misdiagnosed or its diagnosis is ‘missed’ in general psychiatric settings and this article highlights some reasons for this.

This article gives a general overview of the current situation in relation to a range of widely recognised and also newly identified types of child maltreatment. The academic and clinical evidence relating to the impact of child maltreatment on the mental and physical health of child victims is substantial and steadily increasing in volume. New types of abuse are being identified, and changing environmental circumstances, which exacerbate the possibility of widely recognised types of child maltreatment occurring, are also being described. These include multi-type maltreatment, female genital mutilation and online child maltreatment. Serious questions may arise regarding neglect of the moral and social development of children and young people who become addicted to online gaming and pornography. Multiple national and local definitions of each of these existing and new forms of maltreatment have been created, some of which are covered here. The impact of these abuses on the physical and mental health and development of child victims in families or settings where abuse or neglect has occurred is discussed.

The association of life events with the onset of various psychiatric disorders is well-known. The body of evidence has highlighted the impact of negative or positive life events on the genesis of common mental disorders, especially depression. These findings have been replicated across different cultures, although the impact of different life events varies between cultures. In addition, the roles of chronic difficulties (defined in Life events and psychiatric disorders, below) and resulting ongoing chronic stress have been shown to contribute to vulnerability to certain mental illnesses. However, data on the impact of life events, especially those perceived as racial, on members of minority ethnic groups are rather sparse. The questions that need to be addressed concern the perception of life events as racial, the role of pervasive and perceived institutional and individual racism, and chronic difficulties.

We review key recent research and guidance for staff working with acutely disturbed psychiatric patients. Assessment of aggressive patients and their situation should enable full risk assessment, which may ideally involve the use of advance directives. We discuss appropriate use of the Mental Health Act 1983 and consider benefits and adverse effects of rapid tranquillisation. We present a simple protocol for oral or intramuscular rapid tranquillisation. Staff using physical restraint should be properly trained and consider sensitively issues of the patient's diginity, gender and the most appropriate location for restraint to occur. Simple precautions can improve safety when working with potentially disturbed patients. Staff need support during and after the management of an aggressive incident.

‘Depot antipsychotics' (‘long-acting injectable antipsychotic medications' or LAIs) are underused in the treatment of schizophrenia (including first episodes) and, possibly, of schizophrenia with comorbid substance use disorders. Patients' and clinicians' beliefs and attitudes, and service barriers, affect best practice and evidence-based care in LAI prescription. Poor medication adherence is a key reason for LAI prescription, but patients receiving LAIs may still relapse or experience significant side-effects. Patients' and clinicians' attitudes towards antipsychotic medication, as well as the quality of their recovery-focused relationship, are key factors in adherence. Clinicians should avoid a dichotomous ‘oral v. LAI’ choice: LAIs may have a place at various stages in the continuum of care and they should be one of the options discussed with any patient requiring long-term treatment, even early in the illness course. Many clinicians need better education about LAIs and greater familiarity with schizophrenia treatment guidelines.

Malingering is the dishonest and intentional production of symptoms. It can cause considerable difficulty as assessment runs counter to normal practice, and it may expose clinicians to testing medicolegal situations. In this first part of a two-article review, we explore types of psychiatric malingering and their occurrence across a range of common and challenging scenarios, discussing presentations that may help delineate true from feigned illness. A framework is provided for undertaking an assessment where malingering is suspected, including recommendations on clinician approach, the use of collateral information, and self-evaluation of biases. The uses, and limitations, of psychometric tests are discussed, including ‘general’, malingering-specific and ‘symptom validity’ scales.

About 6% of older people in the UK are immigrants. Concentrated in deprived inner-city areas, their numbers are rising rapidly, with the ageing of those arriving after the Second World War. Cultural, language and educational differences cause problems in studying this group's mental health. Idioms of distress may affect presentation, help-seeking behaviour and acceptability of treatment. Ethnic elders may be considered vulnerable to depression because of socio-economic deprivation, immigrant status and old age but studies are contradictory and may use inappropriate screening instruments. Relatively few consider immigrant status and dementia. Uncontrolled hypertension could relate to higher dementia rates in Black immigrants which are not reflected in the country of origin. No genetic risk has been found. There is potential for prevention in this population.

Mistakes are inevitable in any branch of medicine, but psychiatry is a particularly risky business (Holloway, 1997). When psychiatrists get it wrong there may serious consequences for their patients, the clinical team and the wider public. The Government introduced a series of initiatives in the 1990s: the Care Programme Approach (1990), the supervision register (Department of Health & Home Office, 1994) and supervised discharge (Secretary of State for Health, 1997). One of the main purposes of this legislation was to minimise the risk psychiatric patients pose to the community. Future service provision will be shaped by clinical governance and the National Service Framework for Mental Health (Secretary of State for Health, 1997), and evaluation and management of risk will become increasingly important.

This article reviews how data on the benefits and hazards of antidepressants have been analysed, and how conclusions drawn from these analyses conflict with the data. Randomised trials of antidepressants have for two decades consistently shown evidence of an increased risk of suicidal acts on active treatment compared with placebo, but an inappropriate application of significance testing has led to this evidence being dismissed. During the same period a minority of antidepressant trials have produced data indicative of benefits that have reached statistical significance at a 95% level. In this case significance testing appears to have led to an unrealistic impression of the likely benefits of treatment in practice. Current approaches to evidence-based medicine risk perpetuating misunderstandings of this type. Against a background of current developments in healthcare delivery, clinicians might need to reconsider how they handle and present clinical trial data.

The targeting of services to groups with special needs is today commonplace in enlightened public health policies. To list men among the ‘minorities’ in need of such special help might have the semblance of satire. This air of levity is not really reduced by listing male's shorter life expectancy, higher infant mortality and higher rates of natural and unnatural deaths in all age groups (Drever & Bunting, 1997; Kelly & Bunting, 1998).
