RESUMO
BACKGROUND: Psychiatric in-patients have a greatly elevated risk of suicide. We aimed to examine trends in in-patient suicide rates and determine if characteristics of in-patients who died by suicide have changed over time. METHODS: We identified all in-patients in England who died by suicide between 2009 and 2020 from the National Confidential Inquiry into Suicide and Safety in Mental Health. Suicide rates were calculated using data from Hospital Episodes Statistics. RESULTS: The rate of in-patient suicide per 100 000 bed days fell by 41.9% between 2009-2011 and 2018-2020. However, since 2016 the rate has remained static with no significant fall. Rates fell in men, those aged 30-59, and those with schizophrenia and other delusional disorders or personality disorder. Rates also fell for suicide by hanging (including hanging on the ward) and jumping. No falls were seen in suicide rates among women, younger and older age groups, and those with affective disorder. There was no indication of a transfer of risk to the post-discharge period or to home treatment/crisis care. More in-patients in the latter part of the study were aged under 25, were on authorised leave, and had psychiatric comorbidity. CONCLUSIONS: In-patient suicide has significantly fallen since 2009, suggesting patient safety may have improved. The recent slowdown in the fall in rates, however, highlights that renewed preventative efforts are needed. These should include a greater focus on women, younger and older patients, and those with affective disorder. Careful reviews prior to granting leave are important to ensure a safe transition into the community.

BACKGROUND: The risk of suicide is complex and often a result of multiple interacting factors. Understanding which groups of the population are most at risk of suicide is important to inform the development of targeted public health interventions. METHODS: We used a novel linked dataset that combined the 2011 Census with the population-level mortality data in England and Wales. We fitted generalized linear models with a Poisson link function to estimate the rates of suicide across different sociodemographic groups and to identify which characteristics are independent predictors of suicide. RESULTS: Overall, the highest rates of suicide were among men aged 40-50 years, individuals who reported having a disability or long-term health problem, those who were unemployed long term or never had worked, and those who were single or separated. After adjusting for other characteristics such as employment status, having a disability or long-term health problem, was still found to increase the incidence of suicide relative to those without impairment [incidence rate ratio minimally adjusted (women) = 3.5, 95% confidence interval (CI) = 3.3-3.6; fully adjusted (women) 3.1, 95% CI = 3.0-3.3]. Additionally, while the absolute rate of suicide was lower in women compared with men, the relative risk in people reporting impairments compared with those who do not was higher in women compared with men. CONCLUSIONS: The findings of this work provide novel population-level insights into the risk of suicide by sociodemographic characteristics in England and Wales. Our results highlight several sociodemographic groups who may benefit from more targeted suicide prevention policies and practices.

BACKGROUND: There are comparatively few international studies investigating suicide in military veterans and no recent UK-wide studies. This is important because the wider context of being a UK Armed Forces (UKAF) veteran has changed in recent years following a period of intensive operations. We aimed to investigate the rate, timing, and risk factors for suicide in personnel who left the UKAF over a 23-year period. METHODS AND FINDINGS: We carried out a retrospective cohort study of suicide in personnel who left the regular UKAF between 1996 and 2018 linking national databases of discharged personnel and suicide deaths, using survival analysis to examine the risk of suicide in veterans compared to the general population and conditional logistic regression to investigate factors most strongly associated with suicide after discharge. The 458,058 individuals who left the UKAF accumulated over 5,852,100 person years at risk, with a median length of follow-up of 13 years, were mostly male (91%), and had a median age of 26 years at discharge. 1,086 (0.2%) died by suicide. The overall rate of suicide in veterans was slightly lower than the general population (standardised mortality ratio, SMR [95% confidence interval, CI] 94 [88 to 99]). However, suicide risk was 2 to 3 times higher in male and female veterans aged under 25 years than in the same age groups in the general population (age-specific mortality ratios ranging from 160 to 409). Male veterans aged 35 years and older were at reduced risk of suicide (age-specific mortality ratios 47 to 80). Male sex, Army service, discharge between the ages of 16 and 34 years, being untrained on discharge, and length of service under 10 years were associated with higher suicide risk. Factors associated with reduced risk included being married, a higher rank, and deployment on combat operations. The rate of contact with specialist NHS mental health services (273/1,086, 25%) was lowest in the youngest age groups (10% for 16- to 19-year-olds; 23% for 20- to 24-year-olds). Study limitations include the fact that information on veterans was obtained from administrative databases and the role of pre-service vulnerabilities and other factors that may have influenced later suicide risk could not be explored. In addition, information on contact with support services was only available for veterans in contact with specialist NHS mental health services and not for those in contact with other health and social care services. CONCLUSIONS: In this study, we found suicide risk in personnel leaving the UKAF was not high but there are important differences according to age, with higher risk in young men and women. We found a number of factors which elevated the risk of suicide but deployment was associated with lower risk. The focus should be on improving and maintaining access to mental health care and social support for young service leavers, as well as implementing general suicide prevention measures for all veterans regardless of age.

BACKGROUND: Doctors, including junior doctors, are vulnerable to greater levels of distress and mental health difficulties than the public. This is exacerbated by their working conditions and cultures. While this vulnerability has been known for many years, little action has been taken to protect and support junior doctors working in the NHS. As such, we present a series of recommendations from the perspective of junior doctors and other relevant stakeholders, designed to improve junior doctors' working conditions and, thus, their mental health. METHODS: We interviewed 36 junior doctors, asking them for recommendations for improving their working conditions and culture. Additionally, we held an online stakeholder meeting with a variety of healthcare professionals (including junior doctors), undergraduate medical school leads, postgraduate speciality school leads and NHS policymakers where we asked what could be done to improve junior doctors' working conditions. We combined interview data with notes from the stakeholder discussions to produce this set of recommendations. RESULTS: Junior doctor participants and stakeholders made organisational and interpersonal recommendations. Organisational recommendations include the need for more environmental, staff and educational resources as well as changes to rotas. Interpersonal recommendations include changes to communication and recommendations for better support and teamwork. CONCLUSION: We suggest that NHS policymakers, employers and managers consider and hopefully implement the recommendations set out by the study participants and stakeholders as reported in this paper and that the gold standards of practice which are reported here (such as examples of positive learning environments and supportive supervision) are showcased so that others can learn from them.

BACKGROUND: Homicide rates have fallen markedly in the UK over the past decade. There has been little research on whether homicides by people with mental disorder have contributed to this downward trend. Furthermore, there is limited information on trends in court outcomes for people with mental disorder who commit homicide. AIMS: To examine trends in general population homicide and homicide by people with mental disorder, and to explore court outcome. METHOD: We conducted a national, consecutive case series of homicide in England and Wales (1997-2015). Data were received from the Home Office Statistics Unit of Home Office Science. Clinical information was obtained from psychiatric reports and mental health services. RESULTS: There has been a fall in the homicide rate in England and Wales since 2008. Despite this, the relative contribution of mental disorder as a proportion of all homicide has increased. Our findings also showed the inappropriate management of people with serious mental illness convicted of homicide. Of those who committed homicide and were diagnosed with schizophrenia, a third were imprisoned, and there was a marked fall in hospital order referrals. We found this to be linked to substance misuse comorbidity. CONCLUSIONS: The proportional increase in homicide by people with schizophrenia suggests more complex factors may be driving rates, such as substance misuse. Addressing substance misuse comorbidity and maintaining engagement with services may help prevent patient homicide. Despite their complex needs, people with serious mental illness continue to be imprisoned. Improvements in assessment and the timely transfer of prisoners to health services are required.
RESUMO
Parricide is a rare type of homicide in which mental illness is often an important factor. The aims of this study were (a) to describe the characteristics of parricide offenders with a focus on mental illness and clinical care and (b) to examine Heide's widely used typology of parricide through a data-driven approach. We analyzed all homicides in England and Wales between 1997 and 2014. Parricide offenders in our sample were most often male, unmarried, and unemployed, with a third of offenders diagnosed with schizophrenia; 28% had been in contact with mental health services before the offense. The latent class analysis resulted in three types of parricide offenders: middle-aged with affective disorder, previously abused, and seriously mentally Ill, which confirmed, to an extent, Heide's typology. Health and social care services should actively engage with carers of people with mental illness and support to those caring for older relatives and victims of abuse.

BACKGROUND: The 2008 economic recession was associated with an increase in suicide internationally. Studies have focused on the impact in the general population with little consideration of the effect on people with a mental illness.AimsTo investigate suicide trends related to the recession in mental health patients in England. METHOD: Using regression models, we studied suicide trends in mental health patients in England before, during and after the recession and examined the demographic and clinical characteristics of the patients. We used data from the National Confidential Inquiry into Suicide and Safety in Mental Health, a national data-set of all suicide deaths in the UK that includes detailed clinical information on those seen by services in the last 12 months before death. RESULTS: Between 2000 and 2016, there were 21 224 suicide deaths by patients aged 16 or over. For male patients, following a steady fall of 0.5% per quarter before the recession (quarterly percent change (QPC) 2000-2009 -0.46%, 95% CI -0.66 to -0.27), suicide rates showed an upward trend during the recession (QPC 2009-2011 2.37%, 95% CI -0.22 to 5.04). Recession-related rises in suicide were found in men aged 45-54 years, those who were unemployed or had a diagnosis of substance dependence/misuse. Between 2012 and 2016 there was a decrease in suicide in male patients despite an increasing number of patients treated. No significant recession-related trends were found in women. CONCLUSIONS: Recession-associated increases in suicide were seen in male mental health patients as well as the male general population, with those in mid-life at particular risk. Support and targeted interventions for patients with financial difficulties may help reduce the risk at times of economic hardship. Factors such as drug and alcohol misuse also need to be considered. Recent decreases in suicide may be related to an improved economic context or better mental healthcare.Declaration of interestN.K. is supported by Greater Manchester Mental Health NHS Foundation Trust.

RESUMO
BACKGROUND: In England suicide rates are highest in midlife (defined as age 40-59). Despite a strong link with suicide there has been little focus on self-harm in this age group.AimTo describe characteristics and treatment needs of people in midlife who present to hospital following self-harm. METHOD: Data from the Multicentre Study of Self-harm in England were used to examine rates over time and characteristics of men and women who self-harm in midlife. Data (2000-2013) were collected via specialist assessments or hospital records. Trends were assessed by negative binomial regression models. Comparative analysis used logistic regression models for binary outcomes. Repetition and suicide mortality were assessed by Cox proportional hazards models. RESULTS: A quarter of self-harm presentations were made by people in midlife (n = 24 599, 26%). Incidence rates increased over time in men, especially after 2008 (incidence rate ratio [IRR] 1.07, 95% CI 1.02-1.12, P < 0.01), and were positively correlated with national suicide incidence rates (r = 0.52, P = 0.05). Rates in women remained relatively stable (IRR 1.00, 95% CI 1.00-1.02, P = 0.39) and were not correlated with suicide. Alcohol use, unemployment, housing and financial factors were more common in men; whereas indicators of poor mental health were more common in women. In men and women 12-month repetition was 25%, and during follow-up 2.8% of men and 1.2% of women died by suicide. CONCLUSION: Self-harm in midlife represents a key target for intervention. Addressing underlying issues, alcohol use and economic factors may help prevent further self-harm and suicide.Declaration of interestK.H. and N.K. are members of the Department of Health's National Suicide Prevention Advisory Group.

RESUMO
BACKGROUND: Suicide and non-fatal self-harm represent key patient safety events in mental healthcare services. However, additional important learning can also be derived by highlighting examples of optimal practice that help to keep patients safe. In this study, we aimed to explore clinicians' views of what constitutes good practice in mental healthcare services in the context of suicide prevention. METHODS: Data were extracted from the National Confidential Inquiry into Suicide and Safety in Mental Health (NCISH) database, a consecutive case series study of suicide by people in contact with mental healthcare services. A large national sample of clinicians' responses was analysed with a hybrid thematic analysis. RESULTS: Responses (n = 2331) were submitted by clinicians across 62 mental healthcare providers. The following five themes illustrated good practice that helps to: 1) promote safer environments, 2) develop stronger relationships with patients and families, 3) provide timely access to tailored and appropriate care, 4) facilitate seamless transitions, and 5) establish a sufficiently skilled, resourced and supported staff team. CONCLUSION: This study highlighted clinicians' views on key elements of good practice in mental health services. Respondents included practice specific to mental health services that focus on enhancing patient safety via prevention of self-harm and suicide. Clinicians possess important understanding of optimal practice but there are few opportunities to share such insight on a broader scale. A further challenge is to implement optimal practice into routine, daily care to improve patient safety and reduce suicide risk.

BACKGROUND: Patients admitted to hospital at the weekend appear to be at increased risk of death compared with those admitted at other times. However, a 'weekend effect' has rarely been explored in mental health and there may also be other times of year when patients are vulnerable. AIMS: To investigate the timing of suicide in high-risk mental health patients. METHOD: We compared the incidence of suicide at the weekend v. during the week, and also in August (the month of junior doctor changeover) v. other months in in-patients, patients within 3 months of discharge and patients under the care of crisis resolution home treatment (CRHT) teams (2001-2013). RESULTS: The incidence of suicide was lower at the weekends for each group (incidence rate ratio (IRR) = 0.88 (95% CI 0.79-0.99) for in-patients, IRR = 0.85 (95% CI 0.78-0.92) for post-discharge patients, IRR = 0.87 (95% CI 0.78-0.97) for CRHT patients). Patients who died by suicide were also less likely to have been admitted at weekends than during the week (IRR = 0.52 (95% CI 0.45-0.60)). The incidence of suicide in August was not significantly different from other months. CONCLUSIONS: We found evidence of a weekend effect for suicide risk among high-risk mental health patients, but with a 12-15% lower incidence at weekends. Our study does not support the claim that safety is compromised at weekends, at least in mental health services.

PURPOSE: There is a lack of robust empirical research examining mental disorder and homicide-suicide. Primary care medical records are seldom used in homicide-suicide research. The aims of this study were to describe the characteristics of offenders and victims; determine the prevalence of mental disorder and contact with mental health services and examine adverse events prior to the offence. METHODS: This was a mixed-methods study based on a consecutive case series of offences in England and Wales occurring between 2006 and 2008. 60 homicide-suicides were recorded. Data sources included coroner's records, police files, General Practice (GP) and specialist mental health records, and newspaper articles. RESULTS: The results show that most victims were spouse/partners and/or children. Most perpetrators were male (88 %) and most victims were female (77 %). The incidents were commonly preceded by relationship breakdown and separation. 62 % had mental health problems. A quarter visited a GP for emotional distress within a month of the incident. Few had been in recent contact with mental health services before the incident (12 %). Self-harm (26 %) and domestic violence (39 %) were common. CONCLUSION: In conclusion, GPs cannot be expected to prevent homicide-suicide directly, but they can reduce risk generally, via the treatment of depression and recognising the risks associated with domestic violence.

BACKGROUND: Personality disorder (PD) is associated with elevated suicide risk, but the level of risk in primary care settings is unknown. We assessed whether PD among primary care patients is linked with a greater elevation in risk as compared with other psychiatric diagnoses, and whether the association is modified by gender, age, type of PD, and comorbid alcohol misuse. METHODS: Using data from the UK Clinical Practice Research Datalink, 2384 suicides were matched to 46,899 living controls by gender, age, and registered practice. Prevalence of PD, other mental disorders, and alcohol misuse was calculated for cases and controls separately and conditional logistic regression models were used to estimate exposure odds ratios. We also fitted gender interaction terms and formally tested their significance, and estimated gender age-specific effects. RESULTS: We found a 20-fold increase in suicide risk for patients with PD versus no recorded psychiatric disorder, and a four-fold increase versus all other psychiatric illnesses combined. Borderline PD and PD with comorbid alcohol misuse were associated with a 37- and 45-fold increased risk, respectively, compared with those with no psychiatric disorders. Relative risks were higher for female than for male patients with PD. Significant risks associated with PD diagnosis were identified across all age ranges, although the greatest elevations were in the younger age ranges, 16-39 years. CONCLUSIONS: The large elevation in suicide risk among patients diagnosed with PD and comorbid alcohol misuse is a particular concern. GPs have a potentially key role to play in intervening with patients diagnosed with PD, particularly in the presence of comorbid alcohol misuse, which may help reduce suicide risk. This would mean working with specialist care, agreed clinical pathways and availability of services for comorbidities such as alcohol misuse, as well as opportunities for GPs to develop specific clinical skills.

BACKGROUND: Absconding from inpatient care is associated with suicide risk in psychiatric populations. However, little is known about the real world context of suicide after absconding from a psychiatric ward or the experiences of clinical staff caring for these patients. AIMS: To identify the characteristics of inpatients who died by suicide after absconding and to explore these and further key issues related to suicide risk from the perspective of clinical staff. METHODS: A mixed-methods study using quantitative data of all patient suicides in England between 1997 and 2011 and a thematic analysis of semi-structured interviews with 21 clinical staff. RESULTS: Four themes were identified as areas of concern for clinicians: problems with ward design, staffing problems, difficulties in assessing risk, and patient specific factors. CONCLUSIONS: Results suggest that inpatients who died by suicide after absconding may have more complex and severe illness along with difficult life events, such as homelessness. Closer monitoring of inpatients and access points, and improved risk assessments are important to reduce suicide in this patient group.

The elevated risk of suicide in prison and after release is a well-recognised and serious problem. Despite this, evidence concerning community-based offenders' suicide risk is sparse. We conducted a population-based nested case-control study of all people in a community justice pathway in England and Wales. Our data show 13% of general population suicides were in community justice pathways before death. Suicide risks were highest among individuals receiving police cautions, and those having recent, or impending prosecution for sexual offences. Findings have implications for the training and practice of clinicians identifying and assessing suicidality, and offering support to those at elevated risk.

BACKGROUND: Psychiatric illness, substance misuse, suicidality, criminality and premature death represent major public health challenges that afflict a sizeable proportion of young people. However, studies of multiple adverse outcomes in the same cohort at risk are rare. In a national Danish cohort we estimated sex- and age-specific incidence rates and absolute risks of these outcomes between adolescence and early middle age. METHODS: Using interlinked registers, persons born in Denmark 1966-1996 were followed from their 15(th) until 40(th) birthday or December 2011 (N = 2,070,904). We estimated sex- and age-specific incidence rates of nine adverse outcomes, in three main categories: Premature mortality (all-causes, suicide, accident); Psychiatric morbidity (any mental illness diagnosis, suicide attempt, alcohol or drug misuse disorder); Criminality (violent offending, receiving custodial sentence, driving under influence of alcohol or drugs). Cumulative incidences were also calculated using competing risk survival analyses. RESULTS: For cohort members alive on their 15(th) birthday, the absolute risks of dying by age 40 were 1.99 % for males [95 % confidence interval (CI) 1.95-2.03 %] and 0.85 % for females (95 % CI 0.83-0.88 %). The risks of substance misuse and criminality were also much higher for males, especially younger males, than for females. Specifically, the risk of a first conviction for a violent offence was highest amongst males aged below 20. Females, however, were more likely than males to have a hospital-treated psychiatric disorder. By age 40, 13.25 % of females (95 % CI 13.16-13.33 %) and 9.98 % of males (95 % CI 9.91-10.06 %) had been treated. Women aged below 25 were also more likely than men to first attempt suicide, but this pattern was reversed beyond this age. The greatest gender differentials in incidence rates were in criminality outcomes. CONCLUSIONS: This is the first comprehensive assessment of the incidence rates and absolute risks of these multiple adverse outcomes. Approximately 1 in 50 males and 1 in 120 females who are alive on their 15th birthday will die by age 40. By examining the same cohort at risk, we compared risks for multiple outcomes without differential inter-cohort biases. These epidemiological profiles will inform further research into the pathways leading to these adverse events and future preventive strategies.

BACKGROUND: Although studies have suggested a high risk of suicide in people with eating disorders, most studies have focused on suicidal ideation and attempts. There is little research on the characteristics of people with eating disorders who died by suicide, nor investigation of trends over time. We aimed to compare the characteristics of patients with eating disorders who died by suicide versus patients with other mental health diagnoses who died by suicide in England and to examine the trends in rates. METHODS: In this national retrospective cohort study, data on all people (aged ≥10 years) who died by suicide in England, UK, between Jan 1, 1997, and Dec 31, 2021, while under the care (within the previous 12 months) of mental health services were obtained from the National Confidential Inquiry into Suicide and Safety in Mental Health (NCISH), in which clinical information is collected via a questionnaire completed by the mental health professional responsible for the patient's care. Incidence of suicide in, and demographic, clinical, and treatment characteristics of, patients with a diagnosis of eating disorder (as recorded by the treating clinician) who died by suicide were compared with patients with other mental health diagnoses who died by suicide within the same timeframe using univariable logistic regression analysis. People with related lived experience were involved in the study design, implementation, interpretation, and writing of the manuscript. FINDINGS: Of 119â446 people for whom NCISH were notified of dying by suicide in England, 30â795 were under the recent care of mental health services, of whom 30â246 had known diagnoses and were included in analyses. Of these individuals, 10â373 (34%) were female and 19â873 (66%) were male; 2236 (8%) were of minority ethnicity; 382 (1%) had a diagnosis of eating disorder and 29â864 (99%) had another mental health diagnosis. Compared with patients with other mental health diagnoses who died by suicide, patients with eating disorders were younger (median age 33 years [range 15-90] vs 45 years [10-100]), more often female (343 [90%] female and 39 [10%] male in the eating disorders group; 10â030 [34%] female and 19â834 [66%] male in the other diagnoses group), and less likely to have evidence of conventional risk factors for suicide such as living alone (odds ratio [OR] 0·68, 95% CI 0·55-0·84). 22 (6%) of 382 were from a minority ethnic group. Patients with an eating disorder were characterised by a greater clinical complexity (eg, self-harm [OR 2·31, 95% CI 1·78-3·00], comorbidity [9·79, 6·81-14·1], and longer duration of illness [1·95, 1·56-2·43]), and were more likely to have died following overdoses (2·00, 1·62-2·45) than patients with other diagnoses. Childhood abuse (52 [37%] of 140) and domestic violence (18 [20%] of 91) were common in patients with eating disorders. Similar to patients with other diagnoses, most (244 [75%] of 326) of those with eating disorders who died by suicide were rated as low risk by clinicians at last contact. The number of suicide deaths in patients with eating disorders rose between 1997 and 2021 (incidence rate ratio [IRR] 1·03, 95% CI 1·02-1·05; p<0·0001), but rates fell when accounting for the greater number of patients entering mental health services (IRR 0·97, 0·95-1·00; p=0·033). INTERPRETATION: This study was focused on people who sought help from mental health services. It did not consider subtypes of eating disorders or include a control group, but it does highlight possible areas for intervention. The comprehensive provision of evidence-based treatment for eating disorders and underlying conditions to address the clinical complexity in these patients might help to reduce suicide. Recognising limitations in clinical risk assessment, addressing early life experiences and current adversities, and appropriate prescribing might also be of benefit. Suicide prevention must remain a priority for eating disorder services and mental health care more widely. FUNDING: The Healthcare Quality Improvement Partnership.

Background: Suicide-related internet use (SRIU) has been shown to be linked to suicide. However, there is limited research on SRIU among mental health patients, who are at 4 to 7 times increased risk of suicide compared to the general population. This study aims to address this gap by exploring the prevalence of SRIU among mental health patients who died by suicide in the UK and describing their characteristics. Methods: The study was carried out as part of the National Confidential Inquiry into Suicide and Safety in Mental Health (NCISH). Data were collected on sociodemographic, clinical, suicide characteristics and engagement in SRIU of patients who died by suicide between 2011 and 2021. The study utilised a case-control design to compare patients who engaged in suicide-related internet use with those who did not. Findings: The presence or absence of SRIU was known for 9875/17,347 (57%) patients; SRIU was known to be present in 759/9875 (8%) patients. The internet was most often used to obtain information on suicide methods (n = 523/759, 69%) and to visit pro-suicide websites (n = 250/759, 33%) with a significant overlap between the two (n = 152/759, 20%). Engaging in SRIU was present across all age groups. The case-control element of the study showed patients who were known to have engaged in SRIU were more likely to have been diagnosed with autism spectrum disorder (OR = 2.13, 95% CI: 1.43-3.18), have a history of childhood abuse (OR = 1.70, 95% CI: 1.36-2.13) and to have received psychological treatment (OR = 1.43, 95% CI: 1.18-1.74) than controls. Additionally, these patients were more likely to have died on or near a salient date (OR = 2.11, 95% CI: 1.61-2.76), such as a birthday or anniversary. Interpretation: The findings affirm SRIU as a feature of suicide among patients of all ages and highlight that clinicians should inquire about SRIU during assessments. Importantly, as the most common type of SRIU can expand knowledge on suicide means, clinicians need to be aware of the association between SRIU and choice of methods. This may be particularly relevant for patients approaching a significant calendar event. Funding: The Healthcare Quality Improvement Partnership.
RESUMO
Suicide is the leading cause of unnatural death among people with schizophrenia. Substance use is a highly prevalent comorbid feature of schizophrenia and a modifiable risk factor for suicide. However, no studies have examined changes in the frequency of substance use or self-poisoning in those who died by suicide over time. Knowing this could support more tailored approaches to reducing specific risk factors and access to means in those with schizophrenia who are at risk of suicide. We conducted an 11-year observational study on a clinical survey of people with schizophrenia in the UK who died by suicide within 12 months of contact with mental health services between 2010 and 2020 (n = 2718). Overall, alcohol, cannabis and stimulants were the most frequently reported substances. The odds of lifetime use significantly increased over time for cannabis, stimulants, heroin, and benzodiazepines. There were differences in socio-demographic, behavioural and clinical factors between those with recent and historical alcohol and drug use before death. Deaths by hanging, jumping and self-poisoning were the most common suicide methods. Though deaths by hanging significantly increased over time, deaths by self-poisoning significantly decreased, especially by means of psychotropic medication and opioids. To improve risk management, clinical efforts should focus on identifying and treating people with schizophrenia using specific substances. Nationwide initiatives for improving safety in prescribing could be contributing to reduced risks of suicide via self-poisoning in this group.
