There is great concern about the access of ethnic minority clients to appropriate healthcare and the treatment they experience once they gain access to services. There have been recent calls for training in cultural diversity to be prioritised for mental healthcare professionals, including psychiatrists. In this article we discuss the term ‘cultural diversity’ and consider its relevance to psychiatrists. We then briefly review some of the training currently available, discussing related issues and problems, including the lack of evaluation. We suggest how psychiatrists may need to change their approach to this subject.

This article summarises the current research evidence base on user involvement in mental health services from both policy and practical perspectives. We begin by examining the many meanings of the term ‘mental health service user’ and the policy imperatives for user involvement, to provide a context for later examples of good practice. We then discuss what is meant by ‘involvement’ and the reasons why user involvement is particularly important in mental health services. Finally, we describe some of the traditional barriers to involvement and a number of examples of positive practice across a range of different aspects of mental health service development and delivery.

The different cultures of doctors and managers and the impact of these on their working relationships are described. A historical resumé tracks organisational change, the evolving nature of the relationship and the stresses it engenders. The phenomenon of scapegoating and an approach to managing risk is explored. Vignettes describing familiar problems, with suggested strategies for analysing them and resolving difficulties, are presented.

Patient risk factors for suicide are well known to psychiatrists, yet the availability of clinically useful, routine and systematic methods for risk recognition are limited. This article outlines the structured professional judgement approach to suicide risk assessment and management. This method combines psychiatric assessment and formulation with the evidence base for suicide risk factors. Structured professional judgement is contrasted with actuarial and clinical judgement approaches. A categorisation of risk factors is presented, with four groups described – static, stable, dynamic and future. Case histories illustrate long-term high risk contrasted with sudden and unpredictable onset of suicidality.

The NHS is an organisation populated by groups who often compete with each other over sparse resources and avenues of influence. Professional rivalry is endemic in this situation as groups position themselves to acquire, consolidate and protect professional territory.

Psychiatric nursing has changed significantly since I wrote a similar article almost 10 years ago. Community psychiatric nurses now focus their attentions almost entirely on people with serious and enduring mental illnesses and undertake case management roles in community teams. Many nurses have now been trained in the use of psychosocial interventions and there have been particular advances in the training of nurses in medication management. In turn, prescribing by nurses has become a reality and this role will expand rapidly over the next few years. Unfortunately, the potential for nurses to deliver cognitive–behavioural therapy to those with common mental disorders has not been realised and it is unlikely that this situation will change. Psychiatric nursing roles have increased in the forensic system and nurses are now working with people with dangerous and severe personality disorders and within prison healthcare. The education and training of nurses has undergone a fundamental shift and nurses of the future are likely to be graduates. Here I discuss the implications of these changes.

Depersonalisation disorder involves an unpleasant, chronic and disabling alteration in the experience of self and environment. In addition to these classic features of depersonalisation and derealisation, symptoms may also encompass alterations in bodily sensation and a loss of emotional reactivity. Primary depersonalisation disorder is probably more common than previously thought, and here we discuss the diagnosis, assessment and treatment of the condition, with particular reference to our experiences in a specialist depersonalisation clinic. We also consider psychological and biological aspects of the condition. Although there is as yet no recognised treatment for this disorder, various pharmacological interventions, particularly a combination of lamotrigine and a selective serotonin reuptake inhibitor, have shown promise. We discuss these drug treatments, together with psychological approaches, in particular a recent cognitive–behavioural conceptualisation and treatment approach.

Epidemiological evidence has identified key strategies that may be used in the prevention of both Alzheimer's disease and vascular dementia. These strategies may be loosely divided into three areas: treatment of vascular risk factors, neuroprotection and increasing neuronal reserves. Evidence from randomised controlled trials already exists for treatment of hypertension but results for statins have been disappointing. Most of the intervention trials currently in progress focus on one or two risk factors and include cognition or dementia only as a secondary outcome. The potential of intervention strategies awaits confirmation by randomised controlled trials that target multiple risk factors in at-risk people with mild cognitive impairment, with incident dementia as the primary outcome.

The care programme approach (CPA) has become an accepted part of clinical practice, despite the continuing lack of strong direct evidence of its value. Guidance from the Department of Health has refined the original requirements, which were to ensure health and social care assessment, discharge from hospital to appropriate accommodation with necessary support, appointment of a mental health professional to draw up a care plan, and coordination of its implementation with necessary follow-up. The CPA now specifies that care plans include provision, as necessary, for risk assessment and management, employment, leisure, accommodation and plans to meet carers' needs. Levels of care have been simplified to ‘standard’ and ‘enhanced’. In future it will need to incorporate issues arising from the development of specialist teams as part of the National Health Service Plan, concern about the physical healthcare of those subject to it and the continuing development of psychosocial interventions.

The incidence of treatment resistance in schizophrenia (failure to respond to antipsychotic therapy) is about 20%. Factors that may contribute to it include non-adherence (non-compliance) to treatment, comorbid conditions and medication side-effects. The National Institute for Clinical Excellence recommends that clozapine be used for schizophrenia resistant to another atypical antipsychotic. Here we focus on patients who are also resistant to clozapine given in adequate dosage for sufficient duration. Switching from clozapine to a previously untried atypical (e.g. olanzapine, risperidone, quetiapine) might be of benefit in partial treatment resistance. In more difficult cases, augmentation of clozapine with benzamides (sulpiride, amisulpride) and anti-epileptics (lamotrigine) shows some success. In extreme treatment resistance, a strategy is recommended that combines the proven best drug for the particular patient and psychosocial treatments.

Disasters are complex events that challenge the coping abilities of individuals and communities. This article reviews the likely impact of such events and factors that compromise the ability of survivors to cope with that impact. The principles of early intervention are also considered, particularly with regard to the role of a mental health adviser. This role is an important and demanding one, and its aims and principles of professional conduct should be carefully scrutinised.
