Substance use and self-poisoning in schizophrenia: 11-year findings from a national clinical survey of suicide in mental health patients in the UK.

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.

Psychiatric in-patient care in England: as safe as it can be? An examination of in-patient suicide between 2009 and 2020.

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.

Suicide among psychiatric patients who migrated to the UK: a national clinical survey.

Background: Within the UK, limited research has examined migration and suicide risk. To assist with tailoring mental health care to the needs of different migrant groups, it is important to identify the clinical profile and antecedents to suicide. Methods: We focussed on two groups of migrants: those resident in the UK for less than 5 years (recent migrants) and those seeking permission to stay in the UK. Data on mental health patients who died by suicide in the UK between 2011 and 2019 were obtained as part of the National Confidential Inquiry into Suicide and Safety in Mental Health. Findings: 13,948 patients died by suicide between 2011 and 2019: 593 were recent migrants with 48 seeking permission to stay in the UK. The overall suicide rate between 2011 and 2017 for patients seeking to stay was 23.8/100,000 (95% CI 17.3-32.1). There was some uncertainty around this estimate but it appeared higher than the general population suicide rate of 10.6/100,000 population (95% CI 10.5-10.7; p = .0001) for the same period. A higher proportion of migrants were from an ethnic minority group (15% recent migrants vs. 70% seeking to remain vs. 7% non-migrants) and more were viewed as at low long-term risk of suicide (63% recent migrants vs. 76% seeking to remain vs. 57% non-migrants). A higher proportion of recent migrants died within three months of discharge from psychiatric in-patient care (19% vs. 14%) compared to non-migrants. Proportionally more patients seeking to remain had a diagnosis of schizophrenia and other delusional disorders (31% vs. 15%) and more had experienced recent life events compared to non-migrants (71% vs. 51%). Interpretation: A higher proportion of migrants had severe or acute illness at the time of their suicide. This may be linked to a range of serious stressors and/or lack of connection with services that could have identified signs of illness early. However, clinicians often viewed these patients as low risk. Mental health services should consider the breadth of stressors migrants may face and adopt a multi-agency approach to suicide prevention.

Suicide bereavement in the UK: Descriptive findings from a national survey.

BACKGROUND: Those bereaved by suicide are a high-risk group of adverse health outcomes and suicidal behavior, yet little is known about the experiences and support needs of these individuals in the UK. METHODS: We conducted a national cross-sectional study using an online survey and analyzed the experiences of 7158 participants who had been bereaved or affected by suicide. RESULTS: Suicide had a major impact on 77% of participants, including those who had lost a friend and those exposed to suicide at a professional level. Mental and physical health problems linked to the suicide were reported in half. Adverse social outcomes and engaging in high-risk behaviors following the suicide were common. Over a third reported suicidal ideation and 8% had attempted suicide as a direct result of the suicide loss. Most had not accessed support services, with the majority viewing provision of local suicide bereavement support as inadequate. CONCLUSIONS: Our results highlight the need for a multi-disciplinary approach in postvention and the provision of proactive outreach to support those bereaved by suicide. Postvention efforts need to acknowledge the death of a friend by suicide as a significant loss.

Ethnic Minority Groups' Experiences of Suicide Bereavement: A Qualitative Exploratory Study.

It is estimated that between 36,000 and 360,000 people are affected by suicide every year in the UK, and a proportion may develop depression and post-traumatic stress disorder, or engage in high-risk behaviours. Recent systematic analyses have revealed a clear gap in research on suicide bereavement in minority ethnic groups. This study aimed to understand the experiences and support needs of individuals from ethnic minority backgrounds bereaved by suicide and was the first in the UK to investigate this matter. The study was a secondary analysis of data. Participants were 7158 people residing in the UK who completed an online survey about their experiences of suicide. Free-text qualitative responses of 227 participants who did not identify as White British were analysed using thematic analysis. Four themes were identified: maladaptive coping strategies, emotional processes following suicide, lack of support from agencies, and the importance of mental health awareness. Ethnic minority groups reported a lack of support despite attempts to engage with services, noted the prevalence of stigma within ethnic minority groups, and expressed a need to tackle this. These preliminary results suggest that ethnic minority individuals require visible and accessible services that can successfully engage with and support them.

Suicide rates by ethnic group among patients in contact with mental health services: an observational cohort study in England and Wales.

BACKGROUND: Recent evidence on suicide rates among psychiatric patients from minority ethnic backgrounds is scarce. We aimed to examine suicide rates among minority ethnic psychiatric patients and describe their social and clinical characteristics. METHODS: We did a retrospective observational cohort study on a national case-series of patients in England and Wales who died by suicide within 12 months of contact with mental health services between 2007 and 2018. Data were collected as part of the National Confidential Inquiry into Suicide and Safety in Mental Health. Suicide rates and standardised mortality ratios (SMRs) were estimated for South Asian (Indian, Pakistani, and Bangladeshi), Black African, Black Caribbean, Chinese, and White patients. FINDINGS: A total of 698 patients in the four minority ethnic groups of South Asian, Black Caribbean, Black African, and Chinese were included (482 [69%] men; 216 [31%] women; mean age 41 years [SD 14·9, range 12-91] and compared with 13 567 White patients (9030 [66·6%] men; 4537 [33·4%] women; mean age 48 years [SD 15·8, range 10-100]). Rates and SMRs for suicide among minority ethnic patients were lower than for White patients (2·73 deaths, 95% CI 2·68-2·78) per 100 000 population. Differences were found between ethnic groups with higher suicide rates in Black Caribbean patients (1·89 deaths [95% CI 1·55-2·23] per 100 000 population) and lower rates in South Asian patients (1·49 deaths [1·33-1·64] per 100 000 population). There was an increase in rates among White patients in 2007-12 followed by a fall but no change among other ethnic groups. Schizophrenia was more common among Black African patients (54%) and Black Caribbean patients (44%), while affective disorder was more common among South Asian patients (41%). Minority ethnic patients overall showed markers of social adversity and received higher intensity care yet were viewed by clinicians as at lower risk than White patients. INTERPRETATION: Effective approaches to prevention might differ between minority ethnic groups. Clinicians and the services in which they work should be aware of the common and distinct social and clinical needs of minority ethnic patients with mental illness.

Suicide risk assessment in UK mental health services: a national mixed-methods study.

BACKGROUND: Risk assessments are a central component of mental health care. Few national studies have been done in the UK on risk assessment tools used in mental health services. We aimed to examine which suicide risk assessment tools are in use in the UK; establish the views of clinicians, carers, and service users on the use of these tools; and identify how risk assessment tools have been used with mental health patients before suicide. METHODS: We did a mixed-methods study involving three components: collection and content analysis of risk assessment tools used by UK mental health services; an online survey of clinicians, service-users, and carers; and qualitative telephone interviews with clinicians on their use of risk assessment tools before a suicide death and their views of these tools. The online survey was advertised through the National Confidential Inquiry into Suicide and Safety in Mental Health's (NCISH) website and social media, and it included both quantitative and open-ended qualitative questions, and respondents were recruited through convenience sampling. For the telephone interviews, we examined the NCISH database to identify clinicians who had been responsible for the care of a patient who died by suicide and who had been viewed as being at low or no immediate risk of suicide. FINDINGS: We obtained 156 risk assessment tools from all 85 National Health Service mental health organisations in the UK, and 85 (one per each organisation) were included in the analysis. We found little consistency in use of these instruments, with 33 (39%) of 85 organisations using locally developed tools. Most tools aimed to predict self-harm or suicidal behaviour (84 [99%] of 85), and scores were used to determine management decisions (80 [94%]). Clinicians described positive aspects of risk tools (facilitating communication and enhancing therapeutic relationships) but also expressed negative views (inadequate training in the use of tools and their time-consuming nature). Both patients and carers reported some positive views, but also emphasised little involvement during risk assessment, and a lack of clarity on what to do in a crisis. INTERPRETATION: Assessment processes need to be consistent across mental health services and include adequate training on how to assess, formulate, and manage suicide risk. An emphasis on patient and carer involvement is needed. In line with national guidance, risk assessment should not be seen as a way to predict future behaviour and should not be used as a means of allocating treatment. Management plans should be personalised and collaboratively developed with patients and their families and carers. FUNDING: The Healthcare Quality Improvement Partnership.

Homicide by men diagnosed with schizophrenia: national case-control study.

BACKGROUND: Some people diagnosed with schizophrenia are more prone to committing acts of serious violence, especially in the presence of drug or alcohol misuse. The rarity of homicide has meant that no large controlled study has previously examined clinical risk factors. AIMS: To determine the risk factors for homicide by males diagnosed with schizophrenia. METHOD: A national nested case-control study of all previously admitted males diagnosed with schizophrenia, convicted of homicide between 1 January 1997 and 31 December 2012. Univariate and multivariable conditional logistic regression models were fitted to identify predictors of homicide in this population. RESULTS: During the observation period 160 male patients with schizophrenia and a history of psychiatric admission were convicted of homicide, and they were matched with 542 male control patients who had not been convicted of homicide. Patients who committed homicide were more likely to have a history of violence and comorbid personality disorder or drug misuse. They were more likely to have missed their last contact with services prior to the offence and to have been non-adherent with their treatment plan. Almost all (94%) of homicides were committed by patients who had a history of alcohol or drug misuse and/or who were not in receipt of planned treatment. CONCLUSIONS: In England and Wales, homicides by patients with schizophrenia without substance misuse and in receipt of planned care are exceptionally rare. To prevent serious violence, mental health services should focus on drug and alcohol misuse, treatment adherence and maintaining contact with services.

Early Post-Discharge Suicide in Mental Health Patients: Findings From a National Clinical Survey.

Studies on suicide by recently discharged mental health patients have reported a high number of deaths in the early post-discharge period, which has led to recommendations of follow-up within 7 days (d). More recently, the National Confidential Inquiry into Suicide and Safety in Mental Health (NCISH) proposed a more "stringent" follow-up period of 2-3 days (d) after discharge. Patients who died within this early time-frame post-discharge were more likely to die before the follow-up appointment occurred. They more often had a primary diagnosis of a personality disorder, self-discharged, and had a higher frequency of death by jumping from a height or in front of the vehicle compared to later deaths. This study provides practical implications for post-discharge management and safety planning. Clinicians should be aware of (1) the increased risk of immediate suicide in the post-discharge period by people with a diagnosis of personality disorder, (2) immediate suicide risk in patients who initiate their own discharge, and (3) the increased risk of death by jumping from a height or in front of the vehicle in the immediate post-discharge period. Our findings support the recent recommendation from NCISH that follow-up should occur within 3 d of discharge from in-patient care.

Treatment of Mental Illness Prior to Suicide: A National Investigation of 12,909 patients, 2001-2016.

OBJECTIVE: Previous research suggests that up to 90% of individuals who die by suicide may have a mental disorder at the time of death but that levels of treatment may be low. This study aimed to examine undertreatment among patients with mental health conditions who died by suicide and to assess the association between patients' clinical and sociodemographic characteristics and treatment receipt. METHODS: The study's sample included 12,909 patients in England and Wales who died by suicide within 12 months of contact with mental health services between 2001 and 2016. All patients had received a diagnosis of bipolar affective disorder, schizophrenia, depression, or an anxiety disorder. Records of patients who were not receiving treatment as recommended by national clinical guidelines at the time of death were examined for levels of nonprescription of treatment and nonadherence. RESULTS: Twenty-four percent of the patients did not receive treatment, 11% had not been prescribed treatment, and 13% were nonadherent with treatment. These proportions differed by diagnosis. After adjustment for main primary diagnosis, analyses showed that being under age 40, unemployment, living alone, drug misuse, medication side effects, and comorbid personality disorder were independently associated with a decreased likelihood of receiving treatment. CONCLUSIONS: One-quarter of patients with mental health conditions who die by suicide may not be receiving relevant interventions at the time of death. Levels of and reasons for nontreatment vary by diagnosis, but measures to address comorbid diagnoses and implement interventions to improve adherence in specific groups could have an impact.

Examining the mechanisms by which adverse life events affect having a history of self-harm, and the protective effect of social support.

BACKGROUND: Psychological models of suicide emphasize perceptions of negative stressors, hopelessness and self-harm as key antecedents to suicidal thoughts/acts. Such models also emphasize the potential protective role of social support in these pathways. However, such pathways have not been tested using population level data. Hence, this study aimed to redress this gap. METHODS: Questionnaire data regarding 24,444 patient suicide deaths were analysed. All individuals died between 1996 and 2015 and were seen by secondary mental health services in England within 12 months before their death. Mediation analyses, using fitted logistic regression models, investigated direct and indirect pathways between negative stressors, hopelessness and a proxy measure of suicide, namely, self-harm history. In addition, the buffering effects of social support were examined in these pathways. RESULTS: There was a direct effect of negative life events on suicidal behaviors. Supporting contemporary psychological models of suicide, a mediated effect via hopelessness and a protective effect of social support were identified. Social support buffered the pathway between stressful life events and hopelessness, with hopelessness decreasing as social support increased. LIMITATIONS: Causal inferences are inappropriate as the design was cross-sectional. A proxy measure of suicidality was utilized (history of self-harm) as all individuals had died by suicide. CONCLUSIONS: This is the first time that population data has been used to test psychological pathways to suicidal acts involving negative stressors, hopelessness and social support. Psychological interventions should focus on increasing social support following negative life events together with ameliorating perceptions of hopelessness.

Access to means of lethal overdose among psychiatric patients with co-morbid physical health problems: Analysis of national suicide case series data from the United Kingdom.

BACKGROUND: Many physical health problems are associated with elevated suicide risk whilst also providing access to means of overdose. We aimed to investigate whether psychiatric patients with physical co-morbidities who die by suicide were more likely than those without co-morbidities to self-poison with non-psychotropic medications. METHODS: We analysed data on 14,648 psychiatric patients who died by suicide in England & Wales during 2004-2015, as recorded by the National Confidential Inquiry into Suicide and Safety in Mental Health. Using logistic regression models adjusted for age, gender, ethnicity, and primary drug dependence/misuse we compared patients diagnosed with physical co-morbidities versus those without to assess whether a greater proportion of the former had died by overdose, and medication prescribed to treat such disorders (e.g. opioids, insulin). RESULTS: 24% (n = 3525) were recorded as having physical co-morbidity. A greater proportion of these individuals died by self-poisoning than those without physical co-morbidity (37% vs. 20%, p < .001; adjusted OR 2.47; 95% CI 2.26-2.70), and they were more likely to have used medications for a physical health disorder in overdose (50% vs. 34%; adjusted OR 2.10; 95% CI 1.80-2.46), particularly opioids (30% vs. 22%; p < .001), paracetamol/opioid compounds (11% vs. 7%, p < .001) and insulin (4% vs. 1%, p < .001). LIMITATIONS: Use of survey data may have resulted in under-reporting of physical health problems and/or overdose medications. CONCLUSIONS: Overdose, rather than hanging, is the leading cause of suicide among psychiatric patients with physical co-morbidities, particularly using non-psychotropic medications. There is potential for means restriction in preventing suicide among these patients.

Recession, recovery and suicide in mental health patients in England: time trend analysis.

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.

Support for Relatives Bereaved by Psychiatric Patient Suicide: National Confidential Inquiry Into Suicide and Homicide Findings.

OBJECTIVES: International suicide prevention strategies recommend providing support to families bereaved by suicide. The study objectives were to measure the proportion of cases in which psychiatric professionals contact next of kin after a patient's suicide and to investigate whether specific, potentially stigmatizing patient characteristics influence whether the family is contacted. METHODS: Annual survey data from England and Wales (2003-2012) were used to identify 11,572 suicide cases among psychiatric patients. Multivariate regression analysis was used to describe the association between specific covariates (chosen on the basis of clinical judgment and the published literature) and the probability that psychiatric staff would contact bereaved relatives of the deceased. RESULTS: Relatives were not contacted after the death in 33% of cases. Contrary to the hypothesis, a violent method of suicide was independently associated with greater likelihood of contact with relatives (adjusted odds ratio=1.67). Four patient factors (forensic history, unemployment, and primary diagnosis of alcohol or drug dependence or misuse) were independently associated with less likelihood of contact with relatives. Patients' race-ethnicity and recent alcohol or drug misuse were not associated with contact with relatives. CONCLUSIONS: Four stigmatizing patient-related factors reduced the likelihood of contacting next of kin after patient suicide, suggesting inequitable access to support after a potentially traumatic bereavement. Given the association of suicide bereavement with suicide attempt, and the possibility of relatives' shared risk factors for suicide, British psychiatric services should provide more support to relatives after patient suicide.

Suicide under crisis resolution home treatment - a key setting for patient safety.

Recent years have seen a substantial increase in the use of crisis resolution home treatment (CRHT) teams as an alternative to psychiatric in-patient admission. We discuss the functions of these services and their effectiveness. Our research suggests high rates of suicide in patients under CRHT. Specific strategies need to be developed to improve patient safety in this setting.

Mental health services, suicide and 7-day working.

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.

Suicide after absconding from inpatient care in England: an exploration of mental health professionals' experiences.

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.

Mental health service changes, organisational factors, and patient suicide in England in 1997-2012: a before-and-after study.

BACKGROUND: Research into which aspects of service provision in mental health are most effective in preventing suicide is sparse. We examined the association between service changes, organisational factors, and suicide rates in a national sample. METHODS: We did a before-and-after analysis of service delivery data and an ecological analysis of organisational characteristics, in relation to suicide rates, in providers of mental health care in England. We also investigated whether the effect of service changes varied according to markers of organisational functioning. FINDINGS: Overall, 19 248 individuals who died by suicide within 12 months of contact with mental health services were included (1997-2012). Various service changes related to ward safety, improved community services, staff training, and implementation of policy and guidance were associated with a lower suicide rate after the introduction of these changes (incidence rate ratios ranged from 0·71 to 0·79, p<0·0001). Some wider organisational factors, such as non-medical staff turnover (Spearman's r=0·34, p=0·01) and incident reporting (0·46, 0·0004), were also related to suicide rates but others, such as staff sickness (-0·12, 0·37) and patient satisfaction (-0·06, 0·64), were not. Service changes had more effect in organisations that had low rates of staff turnover but high rates of overall event reporting. INTERPRETATION: Aspects of mental health service provision might have an effect on suicide rates in clinical populations but the wider organisational context in which service changes are made are likely to be important too. System-wide change implemented across the patient care pathway could be a key strategy for improving patient safety in mental health care.

Suicide in perinatal and non-perinatal women in contact with psychiatric services: 15 year findings from a UK national inquiry.

BACKGROUND: Suicide in pregnant and postnatal women is an important cause of maternal death, but evidence to guide suicide prevention in this group is scarce. We aimed to compare the trend, nature, and correlates of suicide in perinatal and non-perinatal women in contact with psychiatric services. METHODS: We used 1997-2012 data from the UK National Confidential Inquiry into Suicides and Homicides by People with Mental Illness, which includes all suicides by people (age ≥10 years) who had been in contact with psychiatric services in the previous year. The study sample comprised all women who died by suicide in pregnancy or the first postnatal year (perinatal suicides), and all women in the same age range who died by suicide outside this period (non-perinatal suicides). We compared suicides among perinatal and non-perinatal women with logistic regression of multiply imputed data. FINDINGS: The study sample included 4785 women aged 16-50 years who died by suicide, of whom 98 (2%) died in the perinatal period. Of the 1485 women aged 20-35 years, 74 (4%) women died in the perinatal period. Over the course of the study, we recorded a modest downward trend in the mean number of women dying by suicide in the non-perinatal period (-2·07 per year [SD 0·96]; p=0·026), but not the perinatal period (-0·07 per year [0·37]; p=0·58). Compared with non-perinatal women, women who died by suicide in the perinatal period were more likely to have a diagnosis of depression (adjusted odds ratio [OR] 2·19 [95% CI 1·43-3·34]; p<0·001) and less likely to be receiving any active treatment (0·46 [0·24-0·89]; p=0·022) at the time of death. Women who died by suicide within versus outside the perinatal period were also more likely to be younger (crude OR -6·39 [95% CI -8·15 to -4·62]; p<0·0001) and married (4·46 [2·93-6·80]; p<0·0001), with shorter illness duration (2·93 [1·88-4·56]; p<0·001) and no history of alcohol misuse (0·47 [0·24-0·92]; p=0·027). There were no differences in service contact or treatment adherence. INTERPRETATION: In women in contact with UK psychiatric services, suicides in the perinatal period were more likely to occur in those with a depression diagnosis and no active treatment at the time of death. Assertive follow-up and treatment of perinatal women in contact with psychiatric services are needed to address suicide risk in this group.
