Complementary and integrative medicine provides safe, low-cost, effective treatments for conditions ranging from everyday stress to post-traumatic stress disorder. The evidence for herbs, nutrients and mind–body practices is growing, despite disproportionately small amounts of financial support compared with funding for expensive pharmaceuticals. The unsustainable cost of conventional treatments, the moral imperative to care for millions of uninsured and the impact of COVID-19 compel us to fully explore known and potential benefits of treatments being used by complementary and integrative practitioners.

This article summarises key areas of research informing understanding of vulnerability factors and risk assessment and management across the lifespan, with particular reference to risk to self (self-harm and suicide). It relates the discussion to people attending sexual assault referral centres (SARCs), but is applicable in a range of clinical settings. Although people accessing SARCs often present with mental health difficulties and various other vulnerabilities, SARC practitioners often do not have specialist training in working with mental health difficulties, including individuals at risk to self. We discuss developmental differences that should be considered when assessing and managing risk to self, and examine relationships between mental health difficulties, risk to self, and rape and/or sexual assault. Finally, we offer advice on how to respond to risk presented by individuals who have experienced sexual violence.

Delusional infestation (delusional parasitosis) is a relatively rare condition but it has been of interest to a wide range of professionals, including entomologists, zoologists and dermatologists, as patients predominantly seek help from specialties other than psychiatrists. The illness requires a multidisciplinary approach and a strong bond of trust between the treating clinician and the patient to ensure the best possible outcome. This article discusses how clinicians in all specialties should approach patients presenting with the disorder and outlines differential diagnosis and associated laboratory tests. It considers the evidence base for treatment and the success of psychodermatology clinics that provide a ‘neutral setting’ for consultation to address the problem of patients’ non-engagement. Such clinics are few, and there is a need to develop disease-specific pathways in primary care and hospital settings to improve prognosis.

Dual diagnosis is one of several terms used to identify individuals diagnosed with a co-occurring mental disorder and substance use disorder. The existence of a dual diagnosis in adolescents is often associated with functional impairment in various life domains, causing physical health problems, relational conflicts, educational/vocational underachievement and legal problems. Dual diagnosis is difficult to treat and can result in tremendous economic burden on healthcare, education and justice systems. It is essential for clinicians caring for young people to be knowledgeable about dual diagnosis to ensure that it is identified early and treated. This article aims to provide an overview of dual diagnosis, increase its awareness and promote a realistic treatment approach.

The worldwide stress that is a consequence of the COVID-19 pandemic illuminates the need for mental preventive actions. Such ‘mental vaccines’ should be interdisciplinary and culturally sensitive. They should enhance resilience and adaptation of communities as well as vulnerable individuals.

This reflection presents a discussion of some common measures of variability and how they are appropriately used in descriptive and inferential statistical analyses. We argue that confidence intervals (CIs), which incorporate these measures, serve as tools to assess both clinical and statistical significance.

I comment on a new overview of the treatment of delusional infestation. I focus on the challenges of communicating with a patient who has delusions and evaluate practical advice. I look at philosophical models to explain those communication problems as well as theories of delusional formation, and examine how these may help clinicians to understand and overcome those challenges.

Bed management and the transfer of patients is an area of clinical care that is frequently overlooked. Often, the lack of discussion leads to the patient perspective being ignored and to transfers to new hospitals without appropriate handovers, both to the detriment of patient outcomes. This article reflects on the real-world consequences of the bed management systems used within the UK's National Health Service (NHS), using the example of a patient in psychiatric services.

The problem of occupational stress in healthcare workers is hardly new, but effective interventions in this area are lacking despite being sorely needed – especially in the ongoing COVID-19 pandemic. The results of a Cochrane review suggest that cognitive–behavioural therapy and mental and physical relaxation reduce stress more than no intervention but not more than alternative interventions, and that changing work schedules may lead to a reduction of stress. Other organisational interventions showed no effect on stress levels. However, the evidence is of low quality owing to risk of bias and lack of precision. This commentary critically appraises the review and attempts to put its findings into the current real-world context.
