Task-sharing has frequently been proposed as a strategy to overcome human resource shortages in order to scale up mental health care. Although evidence suggests this approach is effective, to date no review has been conducted to assess its acceptability and feasibility among service users and health care practitioners. This review summarises curren...

Background: Agricultural pesticide poisoning is a major contributor to the global burden of suicide. Over the last decade there has been a marked decrease in the incidence of suicide worldwide. It is unclear whether pesticide poisoning still plays a significant role in the global incidence of suicide. Methods: WHO method-specific suicide data we...

Background There has been a recent focus on language use in relation to suicide, with concerns raised about the potential to cause distress, perpetuate stigma and discourage help-seeking. While some terms are promoted as more sensitive than others, empirical research exploring the views of people affected by suicide to inform academic and media gui...

Background The first 4 weeks after initiation and cessation of opioid agonist treatment for opioid dependence are associated with an increased risk of all-cause mortality and overdose. We aimed to investigate whether the rate of self-harm and suicide among people who were prescribed opioid agonist treatment differs during initiation, cessation, and...

Suicide and self-harm are major health and societal issues worldwide, but the greatest burden of both behaviours occurs in low-income and middle-income countries. Although rates of suicide are higher in male than in female individuals, self-harm is more common in female individuals. Rather than having a single cause, suicide and self-harm are the r...

Objective To understand the burden of chronic obstructive pulmonary disease among people who use illicit opioids such as heroin, and evaluate inequalities in treatment. Design Cohort study. Setting Patients registered at primary care practices in England. Participants 106 789 patients in the Clinical Practice Research Datalink with illicit opioi...

There is widespread concern over the potential impact of the COVID-19 pandemic on suicide and self-harm globally, particularly in low- and middle-income countries (LMIC) where the burden of these behaviours is greatest. We synthesised the evidence from the published literature on the impact of the pandemic on suicide and self-harm in LMIC. This rev...

Background In many countries, the average age of people who use illicit opioids, such as heroin, is increasing. This has been suggested to be a reason for increasing numbers of opioid-related deaths seen in surveillance data. We aimed to describe causes of death among people who use illicit opioids in England, how causes of death have changed over...

Introduction There have been longstanding concerns regarding an increased risk of suicide amongst healthcare workers. The Covid-19 pandemic has placed an additional burden on staff, yet few studies have investigated the impact of the pandemic on their risk of suicide and self-harm. We aimed to investigate the cumulative incidence, prevalence and co...

Importance Mortality among people with opioid dependence is higher than that of the general population. Opioid agonist treatment (OAT) is an effective treatment for opioid dependence; however, there has not yet been a systematic review on the relationship between OAT and specific causes of mortality. Objective To estimate the association of time r...

Background: People who use illicit opioids such as heroin have substantial health needs, but there are few longitudinal studies of general health and healthcare in this population. Most research to date has focused on a narrow set of outcomes, including overdoses and HIV or hepatitis infections. We developed and validated a cohort using UK primary...

Background and Aims Recovery outcomes for opioid substitution treatment are poorer than those for alcohol and other drugs. In order to understand why this is and to synthesise the findings of a large number of qualitative studies, we conducted a systematic review and thematic synthesis to understand facilitators of and barriers to recovery from opi...

Background Suicide rates have risen in young people in several high-income countries over the last decade. Reasons for the increases are unclear. Methods We analysed trends in suicide rates in 15-24 year olds over the period 2000-2017 in high-income countries with populations >20 million using Joinpoint analysis. We investigated differences in the...

Background: People with substance use disorder (SUD) are at significantly greater risk of suicide compared with the general population. In recent years the number of suicides resulting from drug poisoning in England and Wales has increased. We sought to identify and evaluate the effect of interventions to prevent suicide or reduce self-harm among...

A commonly encountered problem within memory services is the identification of medications that cause cognitive side‐effects. Here, the authors report on the findings of a clinical audit used to evaluate practice of medical staff against National Institute for Health and Care Excellence (NICE) guidance on the ‘assessment and diagnosis of dementia’....

Background: The rise in Internet use adds a new dimension to suicide prevention. We investigated suicide/self-harm (S/Sh)-related Internet use among patients presenting to hospital with self-harm. Method: We asked 1,198 adult and 315 child and adolescent patients presenting to hospital following self-harm in a city in South West England about In...

Abstract Background Between 1955 and 2011 there were marked fluctuations in suicide rates in Sri Lanka; incidence increased six-fold between 1955 and the 1980s, and halved in the early 21st century. Changes in access to highly toxic pesticides are thought to have influenced this pattern. This study investigates variation in suicide rates across Sri...

Background. Countering stigma is a fundamental facet of suicide prevention efforts. Integral to this is the promotion of accurate and sensitive language. The phrase ‘commit* suicide’ has prompted marked opposition primarily due to the connotations of immorality and illegality. Methods. The study investigated the frequency of the use of the wordstem...

Background Evidence that the internet might be being used in planning suicidal acts, promoting suicidal behaviour, and accessing help, adds a new dimension to suicide prevention. Yet research into the frequency and type of internet use before suicide is lacking. We investigated self-harm related to internet use among patients who presented to hospi...

Improving access and rational use of psychotropic medications in low- and middle-income countries is an important factor in reducing the public health burden resulting from mental illness. This paper considers each component of the medications management cycle to identify current barriers to improvement. Selection is hindered by a lack of up to dat...

Background A major aspect of providing mental healthcare is access to and use of psychotropic medications. Bihar is a state in northeast India with limited mental healthcare provision; consequently access to and utilisation of psychotropic medications are likely to be limited. However, to date there has been no research assessing the situation. Thi...

A major barrier to the large treatment gap in mental healthcare in low- and middle-income countries is the shortage of psychiatrists, partly caused by a brain drain. This qualitative study aimed to gain an in-depth understanding of the motivations and experiences of migrant psychiatrists in order to address retention factors. We interviewed a conve...
