Risk of suicide according to level of psychiatric treatment: a nationwide nested case-control study

Towards a Better Use of Safety Planning in Emergency Departments: An Exploratory Study of Patients and Clinicians' Perspectives

Suicidality frequently leads to emergency department (ED) visits, yet few interventions are offered in EDs to mitigate suicide risk. This study uses a descriptive interpretative design to evaluate the key components for a successful use of such an intervention, the Stanley-Brown safety plan, in EDs. Semi-structured interviews were conducted with patients and ED clinicians and were analyzed using a thematic analysis approach. Participants' perspectives revealed 6 key recommendations for a successful use of the safety plan in EDs: (1) personalize the content of the safety plan, (2) offer a variety of formats, (3) avoid periods of high emotional intensity, (4) engage a broad range of professionals in safety planning, (5) use limited time to make meaningful interventions, (6) propose alternative interventions. A change in the ED culture is needed to ensure that the management of suicidal patients in EDs includes brief therapeutic interventions like safety planning, to mitigate suicide risk.

The problem of suicidality, personality disorder, and treatment: an alternative psycho-social perspective

Suicidal behaviour, including both attempted and completed suicides, has been increasing globally, particularly in industrialized nations, making suicidality a significant public health concern. Despite the allocation of increasing resources by US, EU, and UK governmental and mental health bodies, the effectiveness of current strategies for the treatment, management, and prevention of suicide remains in question. This paper reviews evidence from epidemiological studies and national prevention policies, alongside research data from a London-based specialist personality disorder treatment centre and clinical case studies from private psychiatric/psychotherapy practice, to explore an alternative psychosocial approach to addressing suicidality. The dominant psychiatric model, which relies heavily on medication, hospitalization, and often coercive methods of control, may have iatrogenic effects, potentially exacerbating the risk of suicide. In contrast, a psychodynamic and psychosocial approach, focused on understanding the underlying psychological dimensions of suicidality, fostering a trusting therapeutic alliance, addressing both internal and external factors contributing to suicidal behaviour, and promoting open dialogue around suicidal thoughts, has shown promise in reducing suicide risk. The findings presented in this paper argue for a rethinking of traditional psychiatric approaches, advocating for a shift toward more personalized, collaborative, and psychologically informed interventions that can more effectively reduce the risk of suicide.

Assessing the risk of intentional self-harm in montelukast users: an updated Sentinel System analysis using ICD-10 coding

BACKGROUND

Montelukast prescribing information includes a Boxed Warning issued in March 2020 regarding neuropsychiatric adverse events. A previous Sentinel System study of asthma patients from 2000 to 2015 did not demonstrate an increased risk of intentional self-harm measured using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes, with montelukast compared to inhaled corticosteroids (ICS).

METHODS

Using a new user cohort study design, we examined intentional self-harm events in patients aged 10 years and older who were incident users of either montelukast or ICS as monotherapy, with a diagnosis of asthma, between October 1, 2015, to June 30, 2022, in the Sentinel System. We measured intentional self-harm using ICD-10-CM codes, which may have better accuracy for capturing suicide attempts than ICD-9-CM codes. We used inverse probability of treatment weighting to balance baseline covariates. We performed subgroup analyses by age group, sex, psychiatric history, and pre/post Boxed Warning era and conducted sensitivity analyses varying type of care setting of the outcome and exposure episode gaps.

RESULTS

Among 752,230 and 724,855 patients in the montelukast and ICS exposure groups respectively, we found no association between montelukast use and self-harm compared to ICS use [Hazard Ratio (95% Confidence Interval): 0.96 (0.85, 1.08)]. This finding was consistent across all subgroups, and sensitivity analyses.

CONCLUSION

Our results cannot exclude other neuropsychiatric idiosyncratic reactions to montelukast. Compared to the previous Sentinel study, this study identified about double the rate of self-harm events, suggesting a greater sensitivity of ICD-10 codes for measuring self-harm than ICD-9.

The Role of Socioeconomic Position in the Association Between Mental Disorders and Mortality: A Systematic Review and Meta-Analysis

Importance

Studies are lacking summarizing how the association between mental disorders and mortality varies by socioeconomic position (SEP), particularly considering different aspects of SEP, specific types of mental disorders, and causes of death.

Objective

To investigate the role of SEP in the association between mental disorders and mortality and the association between SEP and mortality among people with mental disorders.

Data Sources

MEDLINE, Embase, PsycINFO, and Web of Science were searched from January 1, 1980, through April 3, 2023, and a snowball search of reference and citation lists was conducted.

Study Selection

Inclusion criteria were observational studies estimating the associations between different types of mental disorders and mortality, stratified by SEP and between SEP and mortality in people with mental disorders.

Data Extraction and Synthesis

Pairs of reviewers independently extracted data using a predefined data extraction form and assessed the risk of bias using the adapted Newcastle-Ottawa scale. Graphical analyses of the dose-response associations and random-effects meta-analyses were performed. Heterogeneity was explored through meta-regressions and sensitivity analyses.

Main Outcomes and Measures

All-cause and cause-specific mortality.

Results

Of 28 274 articles screened, 71 including more than 4 million people with mental disorders met the inclusion criteria (most of which were conducted in high-income countries). The relative associations between mental disorders and mortality were similar across SEP levels. Among people with mental disorders, belonging to the highest rather than the lowest SEP group was associated with lower all-cause mortality (pooled relative risk [RR], 0.79; 95% CI, 0.73-0.86) and mortality from natural causes (RR, 0.73; 95% CI, 0.62-0.85) and higher mortality from external causes (RR, 1.18; 95% CI, 0.99-1.41). Heterogeneity was high (I2 = 83% to 99%). Results from subgroup, sensitivity, and meta-regression analyses were consistent with those from the main analyses. Evidence on absolute scales, specific diagnoses, and specific causes of death was scarce.

Conclusion and Relevance

This study did not find a sufficient body of evidence that SEP moderated the relative association between mental disorders and mortality, but the underlying mortality rates may differ by SEP group, despite having scarcely been reported. This information gap, together with our findings related to SEP and a possible differential risk between natural and external causes of death in individuals with specific types of mental disorders, warrants further research.

Assessment and management of individuals consulting for a suicidal crisis: A European Delphi method-based consensus guidelines

INTRODUCTION

Managing patient with suicidal thoughts and behaviours presents significant challenges due to the scarcity of robust evidence and clear guidance. This study sought to develop a comprehensive set of practical guidelines for the assessment and management of suicidal crises.

MATERIALS AND METHODS

Utilizing the Delphi methodology, 80 suicide clinician and research experts agreed on a series of recommendations. The process involved two iterative rounds of surveys to assess agreement with drafted recommendations, inviting panellists to comment and vote, culminating in 43 consensus recommendations approved with at least 67% agreement. These consensus recommendations fall into three main categories: clinical assessment, immediate care, and long-term approaches.

RESULTS

The panel formulated 43 recommendations spanning suicidal crisis recognition to continuous long-term care. These guidelines underscore systematic proactive suicide risk screening, in-depth medical and toxicological assessment, and suicide risk appraisal considering personal, clinical factors and collateral information from family. The immediate care directives emphasize a secure environment, continuous risk surveillance, collaborative decision-making, including potential hospitalization, sensible pharmacological management, safety planning, and lethal means restriction counselling. Every discharge should be accompanied by prompt follow-up care incorporating proactive case management and multi-modal approach involving crisis lines, brief contact, and psychotherapeutic and pharmacological interventions.

CONCLUSIONS

This study generated comprehensive guidelines addressing care for individuals in suicidal crises, covering pre- to post-discharge care. These practical recommendations can guide clinicians in managing patients with suicidal thoughts and behaviours, improve patient safety, and ultimately contribute to the prevention of future suicidal crises.

Association of suicide with psychiatric hospitalization in Taiwan

INTRODUCTION

A knowledge gap exists in the relationship between suicide and psychiatric hospitalization in Asia. This study investigated inpatient service utilization before suicide and suicide risk at different periods of hospitalization in Taiwan.

METHODS

Using the National Health Insurance Research Database, we applied a nested case-control design with controls being alive on the date each case died by suicide.

RESULTS

A total of 56 939 suicide cases and 1 138 780 controls were included (2:1 male-to-female ratio). Only 5.7% of suicide cases had a history of psychiatric hospitalization in the preceding year. Patients with a history of psychiatric hospitalization were associated with a higher risk of inpatient and postdischarge suicide than those without prior hospitalization. The risk was greatest in the first postdischarge week, decreased gradually, and remained significantly elevated over 7 years after discharge. The suicide risk increased more in females. Patients with affective disorders had higher inpatient and postdischarge suicide risks than those with schizophrenia spectrum disorders.

DISCUSSION

A low rate of psychiatric hospitalization before suicide implies that inpatient treatment of psychiatric disorders could be enhanced. Community-based approaches to suicide prevention can improve the treatment utilization of those with suicide risk and bridge continuous care from hospital to community.

Premature mortality in young people accessing early intervention youth mental healthcare: data-linkage cohort study

BACKGROUND

Understanding premature mortality risk from suicide and other causes in youth mental health cohorts is essential for delivering effective clinical interventions and secondary prevention strategies.

AIMS

To establish premature mortality risk in young people accessing early intervention mental health services and identify predictors of mortality.

METHOD

State-wide data registers of emergency departments, hospital admissions and mortality were linked to the Brain and Mind Research Register, a longitudinal cohort of 7081 young people accessing early intervention care, between 2008 and 2020. Outcomes were mortality rates and age-standardised mortality ratios (SMR). Cox regression was used to identify predictors of all-cause mortality and deaths due to suicide or accident.

RESULTS

There were 60 deaths (male 63.3%) during the study period, 25 (42%) due to suicide, 19 (32%) from accident or injury and eight (13.3%) where cause was under investigation. All-cause SMR was 2.0 (95% CI 1.6-2.6) but higher for males (5.3, 95% CI 3.8-7.0). The mortality rate from suicide and accidental deaths was 101.56 per 100 000 person-years. Poisoning, whether intentional or accidental, was the single greatest primary cause of death (26.7%). Prior emergency department presentation for poisoning (hazard ratio (HR) 4.40, 95% CI 2.13-9.09) and psychiatric admission (HR 4.01, 95% CI 1.81-8.88) were the strongest predictors of mortality.

CONCLUSION

Premature mortality in young people accessing early intervention mental health services is greatly increased relative to population. Prior health service use and method of self-harm are useful predictors of future mortality. Enhanced care pathways following emergency department presentations should not be limited to those reporting suicidal ideation or intent.

Prevalence of Depression and Predictors of Discharge to a Psychiatric Hospital in Young People with Hospital-Treated Deliberate Self-Poisoning at an Australian Sentinel Unit

OBJECTIVE

Hospital treated deliberate self-poisoning is common in young people. Internationally, estimates of rates of depression in this population are very wide (14.6% to 88%). The aims of this study were to determine the prevalence of depression and the independent predictors of referral for psychiatric hospitalisation in young people (aged 16 to 25 years) following an index episode of hospital treated deliberate self-poisoning.

METHOD

A retrospective cohort study design (n = 1410), with data drawn from a population-based clinical case register. Unadjusted and adjusted estimates of predictors of referral for psychiatric admission (after-care) used logistic regression models.

RESULTS

Prevalence of any depression diagnosis was 35.5% (n = 500); and 25.4% (n = 358) were referred for a psychiatric admission. The adjusted estimates for predictors of psychiatric inpatient referral were: high suicidal level (OR 118.21: CI 95% 63.23-220.99), low/moderate suicidal level (14.27: 9.38-21.72), any depression (2.88: 1.97-4.22), any psychosis (4.06; 1.15-14.36), older age (1.12: 1.04-1.21), and number of support people (0.88: 0.78-0.98).

CONCLUSION

Depression was diagnosed in more than a third and was an independent predictor of psychiatric inpatient referral, so service providers need to account for this level of need in the provision of assessment and after-care services. Evidence-based guidelines for psychiatric inpatient after-care for deliberate self-poisoning and/or depression in young people are limited. Our explanatory model included suicidal level, depression, psychosis, older age, and available support persons, suggesting that the treating clinicians were making these discharge decisions for admission in keeping with those limited guidelines, although the balance of benefits and harms of psychiatric hospitalisation are not established. Future research examining patient experiences, effectiveness of psychiatric hospitalisation, and alternatives to hospitalisation is warranted.

Indigeneity and Likelihood of Discharge to Psychiatric Hospital in an Australian Deliberate Self-Poisoning Hospital-Treated Cohort

Hospital-treated self-harm rates for Aboriginal and Torres Strait Islander (Indigenous) people are at least double those for other Australians. Despite this, limited research has explored the relationship between Indigeneity and the clinical management of hospital-treated deliberate self-harm. A retrospective clinical cohort study (2003-2012) at a regional referral centre (NSW) for deliberate self-poisoning was used to explore the magnitude and direction of the relationship between Indigeneity and discharge destination (psychiatric hospital vs. other) using a series of logistic regressions. There were 149 (4%) Indigenous and 3697 (96%) non-Indigenous deliberate self-poisoning admissions during the study period. One-third (31%) were referred to the psychiatric hospital at discharge; Indigenous 21% (n = 32) vs. non-Indigenous 32% (n = 1175). Those who identified as Indigenous were less likely to be discharged to the psychiatric hospital, OR 0.59 (0.40-0.87) at the univariate level, with little change after sequential adjustment; and AOR 0.34 (0.21-0.73) in the fully adjusted model. The Indigenous cohort had a lower likelihood of psychiatric hospital discharge even after adjustment for variables associated with discharge to the psychiatric hospital highlighting the need for further investigation of the reasons accounting for this differential pattern of clinical management and the effectiveness of differential after-care allocation.

Adverse clinical outcomes among youths with nonsuicidal self-injury and suicide attempts: a longitudinal cohort study

BACKGROUND

More knowledge about risks of clinical outcomes associated with nonsuicidal self-injury (NSSI) and suicide attempts (SAs) is needed to inform risk assessment and intervention.

METHODS

Longitudinal cohort study based on 1,855 youths was clinically assessed for NSSI and SA, and followed up (from December, 2011 to December 2013) for the outcomes; diagnosed self-injury, alcohol/substance use disorder, and psychiatric inpatient care data derived from Swedish registers. Hazard ratios (HRs) and 95% confidence intervals (CIs) of the outcomes were estimated with Cox regressions, and additionally adjusted for the potential effect of sex and the number of clinical assessments. NSSI and SA were treated as time-varying covariates.

RESULTS

Youths with NSSI had elevated risks of all outcomes, compared with youths without NSSI or SA; the HR was 2.3, 95% confidence interval [1.6, 3.4] for self-injury, 1.4 [0.9, 2.1] for alcohol/substance use disorder, and 1.3 [1.0, 1.7] for psychiatric inpatient care. Youths with SA displayed higher risks for the outcomes than the NSSI group; the HR was 5.5 [2.4, 12.6] for self-injury, 2.0 [0.9, 4.4] for alcohol/substance use disorder, and 2.6 [1.5, 4.5] for psychiatric inpatient care. Youths with both NSSI and SA showed similar risks as youths with SA; HR 4.1 [2.0, 8.3] for self-injury, 2.0 [1.1, 4.1] for alcohol/substance use disorder, but a higher risk of psychiatric inpatient care; HR 5.0 [3.1, 7.9]. All results remained virtually unchanged in the adjusted analyses.

CONCLUSIONS

Youths with NSSI and/or SA had higher risks for subsequent adverse clinical outcomes. These excess risks were more pronounced among youths with SA and youths with both NSSI and SA, and the risk for psychiatric inpatient care was particularly high in youths with both NSSI and SA. Our findings suggest that early interventions for youths with NSSI or SA should not exclusively focus on suicide prevention, but also consider the risk of subsequent alcohol/substance use disorder.

Preliminary Evaluation of Lived Experience of Suicide Training: Short-, Medium- and Longer-Term Impacts of Our Voices in Action Training

Despite increased participation and multiple workforce roles of those with lived experience in suicide prevention, there are no evaluated training programs to support this population. This study evaluated a training program aimed to prepare people for these important roles. Survey data at pre-, post- and at three- and 12-month follow-up were used measuring knowledge, attitudes, and self-efficacy, as well as psychological distress as a safety measure. Participants experienced significant gains in knowledge after training, although not all aspects of knowledge were maintained at follow-up. Self-efficacy was examined through confidence and empowerment. Confidence gains were significant at immediate and longer-term follow-up but gains in empowerment were not maintained over time. Participants' positive attitudes improved but this was not significant. There was no indication of increases in psychological distress in participants throughout the training and follow-up periods. Implications of these outcomes are discussed.

Suicide and death by other causes among patients with a severe mental illness: cohort study comparing risks among patients discharged from inpatient care v. those treated in the community

AIMS

People diagnosed with a severe mental illness (SMI) are at elevated risk of dying prematurely compared to the general population. We aimed to understand the additional risk among people with SMI after discharge from inpatient psychiatric care, when many patients experience an acute phase of their illness.

METHODS

In the Clinical Practice Research Datalink (CPRD) GOLD and Aurum datasets, adults aged 18 years and older who were discharged from psychiatric inpatient care in England between 2001 and 2018 with primary diagnoses of SMI (schizophrenia, bipolar disorder, other psychoses) were matched by age and gender with up to five individuals with SMI and without recent hospital stays. Using survival analysis approaches, cumulative incidence and adjusted hazard ratios were estimated for all-cause mortality, external and natural causes of death, and suicide. All analyses were stratified by younger, middle and older ages and also by gender.

RESULTS

In the year after their discharge, the risk of dying by all causes examined was higher than among individuals with SMI who had not received inpatient psychiatric care recently. Suicide risk was 11.6 times (95% CI 6.4-20.9) higher in the first 3 months and remained greater at 2-5 years after discharge (HR 2.3, 1.7-3.2). This risk elevation remained after adjustment for self-harm in the 6 months prior to the discharge date. The relative risk of dying by natural causes was raised in the first 3 months (HR 1.6, 1.3-1.9), with no evidence of elevation during the second year following discharge.

CONCLUSIONS

There is an additional risk of death by suicide and natural causes for people with SMI who have been recently discharged from inpatient care over and above the general risk among people with the same diagnosis who have not recently been treated as an inpatient. This mortality gap shows the importance of continued focus, following discharge, on individuals who require inpatient care.

Inflammation and nitro-oxidative stress in current suicidal attempts and current suicidal ideation: a systematic review and meta-analysis

A meta-analysis showed a significant association between activated immune-inflammatory and nitro-oxidative (IO&NS) pathways and suicide attempts (SA). There is no data on whether recent suicidal ideation (SI) is accompanied by activated IO&NS pathways and whether there are differences between recent SA and SI. The current study searched PubMed, Google Scholar, and Web of Science, for articles published from inception until May 10, 2021, and systematically reviewed and meta-analysed the association between recent SA/SI (<3 months) and IO&NS biomarkers. We included studies which compared psychiatric patients with and without SA and SI and controls (either healthy controls or patients without SA/SI) and used meta-analysis (random-effect model with restricted maximum-likelihood) to delineate effect sizes with 95% confidence intervals (CI). Our search included 59 studies comprising 4.034 SA/SI cases and 12.377 controls. Patients with SA/SI showed activated IO&NS pathways (SMD: 0.299; CI: 0.200; 0.397) when compared to controls. The immune profiles were more strongly associated with SA than with SI, particularly when compared to healthy controls, as evidenced by activated IO&NS (SMD: 0.796; CI: 0.503; 1.089), immune (SMD: 1.409; CI: 0.637; 1.462), inflammatory (SMD: 1.200; CI: 0.584; 1.816), and neurotoxic (SMD: 0.904; CI: 0.431; 1.378) pathways. The effects sizes of the IO&NS, immune and inflammatory profiles were significantly greater in SA than in SI. In conclusion: activated IO&NS pathways are associated with recent SA and SI, and inflammation, T helper-1 activation, nitro-oxidative stress, lowered neuroprotection, and increased neurotoxicity explain at least in part why psychiatric patients show increased suicidal behaviours, especially SA.

Leveraging data science to enhance suicide prevention research: a literature review

OBJECTIVE

The purpose of this research is to identify how data science is applied in suicide prevention literature, describe the current landscape of this literature and highlight areas where data science may be useful for future injury prevention research.

DESIGN

We conducted a literature review of injury prevention and data science in April 2020 and January 2021 in three databases.

METHODS

For the included 99 articles, we extracted the following: (1) author(s) and year; (2) title; (3) study approach (4) reason for applying data science method; (5) data science method type; (6) study description; (7) data source and (8) focus on a disproportionately affected population.

RESULTS

Results showed the literature on data science and suicide more than doubled from 2019 to 2020, with articles with individual-level approaches more prevalent than population-level approaches. Most population-level articles applied data science methods to describe (n=10) outcomes, while most individual-level articles identified risk factors (n=27). Machine learning was the most common data science method applied in the studies (n=48). A wide array of data sources was used for suicide research, with most articles (n=45) using social media and web-based behaviour data. Eleven studies demonstrated the value of applying data science to suicide prevention literature for disproportionately affected groups.

CONCLUSION

Data science techniques proved to be effective tools in describing suicidal thoughts or behaviour, identifying individual risk factors and predicting outcomes. Future research should focus on identifying how data science can be applied in other injury-related topics.

Sex Differences in Determinants of Suicide Risk Preceding Psychiatric Admission: An Electronic Medical Record Study

BACKGROUND

Individuals requiring inpatient psychiatric care represent a group at higher risk of progressing toward suicide attempt. Using electronic medical record (EMR) data collected from psychiatric inpatient admissions, the objective of this study was to identify sex differences in risk factors for suicide plans and/or attempts within the 30 days preceding hospital admission.

METHODS

Resident Assessment Instrument for Mental Health (RAI-MH) intake data were obtained for patients admitted to a Canadian tertiary-care hospital deemed a "threat or danger to self" during a 10-year period (2008-2018). Data was extracted for individuals categorized into three groups: non-suicidal (N = 568), presence of suicide plan (N = 178), and presence of suspected suicide attempt (N = 124) in the 30 days prior to hospital admission. Multivariate logistic regression models were used to examine determinants of suicide risk.

RESULTS

Across all models, diagnosis of depression was the strongest predictor of suicide plan and/or attempt (OR = 5.54, 95% CI = 3.71-8.27, p < 0.001). Comparing clinical symptoms between suicidal and non-suicidal groups at the time of admission, the largest effect sizes were found for hopelessness (p < 0.001, η² = 0.11), and guilt or shame (p < 0.001, η² = 0.09). Female sex was identified as a significant factor for elevated suicidal risk (OR = 1.56, 95% CI = 1.01-2.21, p = 0.01), thus we stratified the regression model by sex to identify specific risk factors for suicide plan and/or attempt for males and females. Among males, having no confidant (OR = 2.13, 95% CI = 1.19-3.80, p = 0.01), presence of recent stressors (OR = 1.95, 95% CI = 1.16-3.29, p = 0.01), and participation in social activities (OR = 1.67, 95% CI = 1.02-2.71, p = 0.04) were important predictors, while among females, younger age (OR = 0.96, 95% CI = 0.94-0.97, p < 0.001) increased odds of suicide plan and/or attempt.

CONCLUSION

EMR-derived findings highlight different psychosocial and clinical determinants for males and females associated with suicide plan or attempt prior to psychiatric admission. Identifying precipitating factors that elevate imminent suicide risk may inform suicide prevention efforts for psychiatric inpatients.

Catalytic Reaction Model of Suicide

Suicide is a devastating outcome of unresolved issues that affect mental health, general wellbeing and socioeconomic stress. The biology of suicidal behavior is still poorly understood, although progress has been made. Suicidal behavior runs in families and genetic studies have provided initial glimpses into potential genes that contribute to suicide risk. Here, we attempt to unify the biology and behavioral dimensions into a model that can guide research in this area. The proposed model envisions suicidal behavior as a catalytic reaction that may result in suicide depending on the conditions, analogously to enzyme catalysis of chemical reactions. A wide array of substrates or reactants, such as hopelessness, depression, debilitating illnesses and diminished motivation can mobilize suicidal thoughts and behaviors (STBs), which can then catalyze the final step/act of suicide. Here, we focus on three biological substrates in particular: threat assessment, motivation to engage in life and impulsivity. Genetic risk factors can affect each of these processes and tilt the balance toward suicidal behavior when existential crises (real or perceived) emerge such as loss of a loved one, sudden changes in social status or serious health issues. Although suicide is a uniquely human behavior, many of the fundamental biological processes are evolutionarily conserved. Insights from animal models may help to shape our understanding of suicidal behavior in man. By examining counterparts of the major biological processes in other organisms, new ideas about the role of genetic risk factors may emerge along with possible therapeutic interventions or preventive measures.

Fear, Neglect, Coercion, and Dehumanization: Is Inpatient Psychiatric Trauma Contributing to a Public Health Crisis?

Inpatient psychiatric hospitalization is often negatively experienced, with previous studies indicating a high frequency of traumatic occurrences. This study aimed to expand upon such research, by obtaining service user perspectives on how inpatient psychiatric hospitalization may constitute an experience of trauma. Relevant posts and comments on the Reddit community r/PsychWardChronicles were collected that described potentially traumatic experiences associated with hospitalization. Reflexive thematic analysis of the data led to the development of 3 themes: neglect and abuse, coercion and obedience, as well as dehumanization and fear. Overall, hospitalization was found to induce significant fear, which eventually acted as a deterrent to seeking future mental healthcare services. Many traumatic occurrences were found to arise from care providers’ behaviors. As hospitalization was experienced to be harmful, many patients reported complying in the hopes of being discharged. Increased fear and traumatic stress due to inpatient stays coupled with the subsequent avoidance of mental health services may contribute to a significant public health problem as many previous patients may then avoid needed mental health support.

Immediate and short-term efficacy of suicide-targeted interventions in suicidal individuals: A systematic review

OBJECTIVES

To address the extreme suicide risk period following a suicidal crisis, we aimed to assess the current evidence for specific healthcare system-based interventions on suicide-related outcomes within one-week or one-month in individuals with current suicidal ideation (SI) or a recent suicide attempt (SA).

METHODS

We performed a database (Medline, Academic Search Complete, PsycARTICLES, the Cochrane library, PubMed) and manual reference search for randomised controlled trials, published between March 2000 and March 2020. Antisuicidal efficacy was defined as SI, SA, or a closely related concept. Quality was assessed with the Cochrane Risk of Bias 2 tool for randomised trials.

RESULTS

Out of 34 trials, five reported ketamine or esketamine superiority over placebo in reducing SI in depressed subjects within one week, while five studies had negative findings. Single trials reported positive results for one-month antisuicidal efficacy of buprenorphine, paroxetine, a crisis response plan, and assertive case management. Most trials were underpowered and had moderate-to-high risk of bias.

CONCLUSIONS

Preliminary mixed evidence suggests the possible utility of several pharmacological (ketamine, esketamine paroxetine, and buprenorphine) and non-pharmacological (a crisis response plan, and assertive case management) interventions. Only the immediate efficacy of ketamine was supported by multiple studies, and replication is needed.

Suicide prevention in psychiatric patients

An increased risk of suicide has been reported for psychiatric patients. In several world regions, an underlying psychiatric disorder is reported in up to 90% of people who die from suicide, though this rate seems to be considerably lower in low- and middle-income countries. Major psychiatric conditions associated with suicidality are mood disorders, alcohol and substance use disorders, borderline personality disorder, and schizophrenia. Comorbidity between different disorders is frequently associated with a higher suicide risk. A history of suicide attempts, feelings of hopelessness, impulsivity and aggression, adverse childhood experiences, severe psychopathology, and somatic disorders are common risk factors for suicide among psychiatric patients. Stressful life events and interpersonal problems, including interpersonal violence, are often triggers. A comprehensive and repeated suicide risk assessment represents the first step for effective suicide prevention. Particular attention should be paid during and after hospitalization, with the first days and weeks after discharge representing the most critical period. Pharmacological treatment of mood disorders and schizophrenia has been shown to have an anti-suicidal effect. A significant reduction of suicidal thoughts and behavior has been reported for cognitive behavioral therapy and dialectical behavior therapy. Brief interventions, including psychoeducation and follow-ups, are associated with a decrease in suicide deaths. Further development of suicide prevention in psychiatric patients will require a better understanding of additional risk and protective factors, such as the role of a person's decision-making capacity and social support, the role of spiritual and religious interventions, and the reduction of the treatment gap in mental health care.

Non-disclosure of suicidal ideation in psychiatric inpatients: Rates and correlates

The study explored how common non-disclosure of suicidal ideation is in a sample of adult psychiatric inpatients (N = 171) plus associated patient characteristics. A large percentage (51.5%) withheld some information on suicidal ideation during admission. In multivariable analyses, correlates of non-disclosure included a diagnosis of emotionally unstable personality disorder, low satisfaction with stay, and symptoms of the suicide crisis syndrome. In univariate analyses, therapists' emotional response to the patient was also a correlate. Findings indicate that among acute psychiatric inpatients, non-disclosure of suicidal ideation is quite common, requiring awareness from clinicians relying on this parameter in suicide risk assessments.

Suicide and suicide attempts in adults: exploring suicide risk 24 months after a psychiatric emergency room visit

Objective:

Suicide risk (including attempted and completed suicide) should be measured over short periods of time after contacting health services. The objective of this study was to identify the patterns of attempted and completed suicides within 24-months of a psychiatric emergency department visit, as well as to investigate predictive risk factors, including sociodemographic and clinical variables, previous suicidal behavior, and service utilization.

Method:

A convenience sample (n=147), recruited at a general hospital’s psychiatric emergency room, included patients with suicidal ideation, suicidal plans or previous suicide attempts. These patients were followed for 24 months, focusing on two main outcomes: attempted and completed suicides.

Results:

After six months there were no completed suicides and 36 suicide attempts, while after 24 months there were seven completed suicides and 69 suicide attempts. A final logistic regression model for suicide attempts at 24 months identified somatic pathology and the number of previous psychiatric hospitalizations as predictive factors, with a good area under the receiver operating characteristic curve.

Conclusions:

The findings showed distinct patterns of attempted and completed suicides over time, indicating the importance of a systematic multidisciplinary suicide risk evaluation in psychiatric emergency rooms.

Medically Treated Self-Injury Among Children and Adolescents: Repeated Attempts and Service Use Over 1 Year

OBJECTIVE

Clinical, demographic, and service use patterns of youths ages 6-18 years who had a medically treated self-injury were examined to understand factors associated with recurrence of such an injury in the subsequent year.

METHODS

This retrospective cohort analysis used data from 31,147 youths who were medically treated for self-injury. Data were from IBM/Watson MarketScan commercial claims and encounters databases (2007-2016). The index self-injury was defined as the first event with an ICD code related to self-injury or suicidal ideation combined with a wound code. Cox proportional hazards regression was used to determine the hazard ratios and 95% confidence intervals (CIs) describing associations with subsequent medically treated self-injury for youths who were hospitalized in psychiatric facilities in the seven days before or after the index self-injury versus those who were not.

RESULTS

Approximately 2% of the 31,147 youths had another medically treated self-injury in the year following the index self-injury. The hospitalized group had higher service use in the years prior to and following their self-injury, but the mean number of outpatient psychiatric visits before the index self-injury did not differ significantly between groups. Hazard ratios for clinical, demographic, and service use variables indicated that those who were hospitalized in psychiatric facilities for the index event were twice as likely (95% CI=1.7-2.7) as those who were not to have another medically treated self-injury in the year after the index event.

CONCLUSIONS

In this retrospective, observational study, psychiatric hospitalization after self-injury was strongly associated with recurrence of self-injury in the subsequent year.

Correlates of Chronic Suicidal Ideation Among Community-Based Minor-Attracted Persons

Elevated suicidal risk has been documented in adults who are sexually attracted to minors but the topic has not been adequately investigated, particularly outside the context of the criminal justice system. In this study, risk factors for chronic suicidal ideation were assessed in 333 community-based minor-attracted persons (95% male) via an online survey. Chronic suicidal ideation was endorsed by 38.1% of the participants but was associated neither to history of sexually engaging with a child nor to prior contact with the criminal justice system. In bivariate logistic regression analyses, significant unadjusted correlates included young age, less education, prior mental health treatment, weaker attraction to adult women, history of sexual abuse in the participants' own childhood, and the psychosocial effect of perceived stigma against pedophilia. In multivariable analysis, all these factors except education were uniquely associated with suicidal ideation. These results identify meaningful clinical risk factors and treatment targets in this population.

Adverse events in psychiatry: a national cohort study in Sweden with a unique psychiatric trigger tool

BACKGROUND

The vast majority of patient safety research has focused on somatic health care. Although specific adverse events (AEs) within psychiatric healthcare have been explored, the overall level and nature of AEs is sparsely investigated.

METHODS

Cohort study using a retrospective record review based on a two-step trigger tool methodology in the charts of randomly selected patients 18 years or older admitted to the psychiatric acute care departments in all Swedish regions from January 1 to June 30, 2017. Hospital care together with corresponding outpatient care were reviewed as a continuum, over a maximum of 3 months. The AEs were categorised according to type, severity and preventability.

RESULTS

In total, the medical records of 2552 patients were reviewed. Among the patients, 50.4% were women and 49.6% were men. The median (range) age was 44 (18-97) years for women and 44.5 (18-93) years for men. In 438 of the reviewed records, 720 AEs were identified, corresponding to the AEs identified in 17.2% [95% confidence interval, 15.7-18.6] of the records. The majority of AEs resulted in less or moderate harm, and 46.2% were considered preventable. Prolonged disease progression and deliberate self-harm were the most common types of AEs. AEs were significantly more common in women (21.5%) than in men (12.7%) but showed no difference between age groups. Severe or catastrophic harm was found in 2.3% of the records, and the majority affected were women (61%). Triggers pointing at deficient quality of care were found in 78% of the records, with the absence of a treatment plan being the most common.

CONCLUSIONS

AEs are common in psychiatric care. Aside from further patient safety work, systematic interventions are also warranted to improve the quality of psychiatric care.

Predictors of emergency department visits for suicidal ideation and suicide attempt

OBJECTIVES

This study investigated predictors of emergency department (ED) visits for suicidal ideation and suicide attempt in 2014-15 among patients at six Quebec emergency departments (ED), using administrative data.

METHODS

Participants (n = 11,778) used ED for suicidal ideation (30.4%); suicide attempt (7.0%); or other reasons (61.7%). A multinomial logistic regression was performed using variables described by the Andersen Behavioral Model.

RESULTS

The odds of ED visits for suicidal ideation or suicide attempt was high for adjustment disorders, personality disorders, and prior ED consultations for mental health (MH) reasons, but lower for schizophrenia spectrum and other psychotic disorders, illness acuity levels 3-5 (low severity), and 3+ consultations with outpatient psychiatrists. The odds of visiting ED for suicidal ideation increased in depressive disorders, and in the 12-17 year age range, but decreased in association with 1-2 outpatient psychiatrist consultations. The odds of suicide attempt also increased with alcohol use disorders and drug-induced disorders, but decreased with specific MH interventions at local community health services centers.

CONCLUSION

increasing access to ambulatory care, and care continuity in outreach programs for acute MH disorders, including substance-related disorders, may reduce ED visits for suicidal ideation and suicide attempt, while improving overall service delivery.

Efficacy of the Home-Based Mental Health Evaluation (HOME) Program for Engaging Patients in Care After Hospitalization

OBJECTIVE

The risk of suicide is elevated in the days and weeks after discharge from a psychiatric hospitalization, and lack of treatment engagement posthospitalization is also associated with suicide. The authors sought to determine whether the Home-Based Mental Health Evaluation [HOME] Program is efficacious in helping patients engage in care after psychiatric hospitalization.

METHODS

This study was a nonrandomized, controlled, two-arm (HOME Program versus enhanced care as usual [E-CARE]) trial that took place at four Department of Veterans Affairs medical centers. Participants (N=302) were patients admitted to a psychiatric inpatient unit. The HOME Program consists of phone- and home-based contacts that include suicide risk assessment, safety planning, and problem-solving around barriers to care. The primary outcome was treatment engagement, as documented in the electronic medical record.

RESULTS

Veterans in the HOME Program group were 1.33 (95% confidence interval [CI]=1.29-1.37) times more likely to engage in treatment, compared with veterans in the E-CARE group (p<0.001). HOME Program participants were estimated to have attended 55% more individual appointments (95% CI=12%-113%, p=0.02), compared with those in the E-CARE group. The adjusted difference in median time to treatment engagement was 15 days (95% CI=3.5-27.0) such that HOME Program participants engaged in treatment more quickly than participants at the E-CARE sites.

CONCLUSIONS

Findings suggest that participation in the HOME Program can help individuals at high risk of suicide engage in care after psychiatric hospitalization.

Mortality and suicide rates in patients discharged from forensic psychiatric wards in Japan

BACKGROUND

Japanese forensic mental health services for patients with psychiatric disorders under the Medical Treatment and Supervision Act was initiated in 2005; however, the prognosis of those patients is not well-known, particularly regarding mortality and suicide. This study aimed to evaluate the all-cause mortality and suicide rate in forensic psychiatric outpatients who had been discharged from forensic psychiatric wards in Japan.

METHODS

Participants included 966 patients who had been discharged from forensic psychiatric wards. Data were collected from July 15, 2005 to July 15, 2018 at 29 of the 33 forensic psychiatric wards in Japan. Only the patients who provided written informed consent were included. We and collaborators at each forensic psychiatric ward identified demographic data of participants from the medical records for the inpatient treatment period. The reintegration coordinators, who belonged to the Ministry of Justice, investigated the prognosis of the participants during the outpatient treatment order period. We then connected demographic data and participants' prognosis for analysis. The crude rates (CRs) and standardized mortality ratios (SMRs) were calculated to analyze all-cause mortality and suicide rates. Univariate analysis was performed to examine the factors associated with all-cause mortality and suicide rates using the Cox proportional hazards ratio model.

RESULTS

The participants included 3.3 times as many men (n=739) compared to women (n=227), and their combined mean age was 47.3 (SD=12.9). The most common primary psychiatric diagnosis was psychotic disorders (81.3%). The mean follow-up period was 790.2 days (SD=369.6). The total observation period was 2091.2 person-years. The CR for all-cause death was 812.9 per 100,000 person-years (95% CI [426.5, 1199.4]), while the SMR for all-cause death was 2.2 (95% CI [1.3, 3.5]). The CR for completed suicide was 478.2 per 100,000 person-years (95% CI [181.8, 774.6]). The suicide SMR was 17.9 (95% CI [8.6, 32.9]) overall, 7.7 (95% CI [2.5, 18.0]) for men, and 79.4 (95% CI [25.8, 185.2]) for women. Univariate analysis showed that women had higher completed suicide risk than men (hazard ratio=3.599, 95% CI [1.041, 12.445]).

CONCLUSION

The all-cause mortality and completed suicide rates were higher in participants than observed in the general population consistent with the results of previous international studies.

Reweighing the Ethical Tradeoffs in the Involuntary Hospitalization of Suicidal Patients

Suicide is the 10th leading cause of death in the United States and the second cause of death among those ages 15-24 years. The current standard of care for suicidality management often involves an involuntary hospitalization deemed necessary by the attending psychiatrist. The purpose of this article is to reexamine the ethical tradeoffs inherent in the current practice of involuntary psychiatric hospitalization for suicidal patients, calling attention to the often-neglected harms inherent in this practice and proposing a path for future research. With accumulating evidence of the harms inherent in civil commitment, we propose that the relative value of this intervention needs to be reevaluated and more efficacious alternatives researched. Three arguments are presented: (1) that inadequate attention has been given to the harms resulting from the use of coercion and the loss of autonomy, (2) that inadequate evidence exists that involuntary hospitalization is an effective method to reduce deaths by suicide, and (3) that some suicidal patients may benefit more from therapeutic interventions that maximize and support autonomy and personal responsibility. Considering this evidence, we argue for a policy that limits the coercive hospitalization of suicidal individuals to those who lack decision-making capacity.

Does Compulsory Admission Prevent Inpatient Suicide Among Patients with Schizophrenia? A Nationwide Cohort Study in Taiwan

OBJECTIVE

The aim of this study was to analyze the risk of inpatient suicide in patients with schizophrenia during 2007-2013 and to determine putative risk factors.

METHODS

We conducted a national population-based cohort study of 2,038 psychiatric inpatients in their first compulsory admission, matched with 8,152 controls who were voluntary inpatients. Only patients with schizophrenia were included in the study. We used data derived from the Taiwanese National Health Insurance Database 2005, comprising 1 million beneficiaries randomly selected from the entire population of Taiwan.

RESULTS

During the follow-up period, 23 and 75 inpatient suicides were observed in the compulsory and control groups, respectively. Kaplan-Meier curves showed that the cumulative incidence rate of inpatient suicide was not significantly different between compulsory and voluntary admissions (log-rank test, p = .206).

CONCLUSIONS

Our results suggest that compulsory admission has no protective effects on risk reduction of inpatient suicide for patients with schizophrenia who are compulsorily admitted compared with voluntarily admitted controls. Clinicians should be more alert for the prevention of inpatient suicide among patients with schizophrenia and consider the close monitoring of inpatient suicide risk in the first week of admission.

How the emergency department four-hour target affects clinical outcomes for patients diagnosed with a personality disorder

Emergency departments (EDs) may already be invalidating environments for patients diagnosed with a personality disorder, with negative attitudes from staff perpetuating patients' feelings of dismissal and rejection. Despite a higher prevalence of patients with personality disorder in health services, including EDs, than the general population, there is a lack of literature on how achieving ED targets may affect this patient group. This article expands on Harden's concept of destructive goal pursuit in relation to the four-hour target and uses the literature to illustrate how pressures to meet the target may distort clinical priorities and result in adverse clinical outcomes for patients. It makes recommendations for practice including using short-stay units in which patients can be treated outside of the target wait time and introducing mental health triage in EDs to improve delivery of psychosocial assessments.

Machine learning methods for developing precision treatment rules with observational data

Clinical trials have identified a variety of predictor variables for use in precision treatment protocols, ranging from clinical biomarkers and symptom profiles to self-report measures of various sorts. Although such variables are informative collectively, none has proven sufficiently powerful to guide optimal treatment selection individually. This has prompted growing interest in the development of composite precision treatment rules (PTRs) that are constructed by combining information across a range of predictors. But this work has been hampered by the generally small samples in randomized clinical trials and the use of suboptimal analysis methods to analyze the resulting data. In this paper, we propose to address the sample size problem by: working with large observational electronic medical record databases rather than controlled clinical trials to develop preliminary PTRs; validating these preliminary PTRs in subsequent pragmatic trials; and using ensemble machine learning methods rather than individual algorithms to carry out statistical analyses to develop the PTRs. The major challenges in this proposed approach are that treatment are not randomly assigned in observational databases and that these databases often lack measures of key prescriptive predictors and mental disorder treatment outcomes. We proposed a tiered case-cohort design approach that uses innovative methods for measuring and balancing baseline covariates and estimating PTRs to address these challenges.

Rates and trends of psychiatric inpatient and postdischarge suicides in Taiwan, 2002-2013: a national register-based study

PURPOSE

In contrast to the downsizing trend of psychiatric beds in the Western world, the psychiatric bed capacity in Taiwan has steadily increased in recent decades. This study aimed to assess the suicide rates and their variations over time among psychiatric inpatients and recently discharged patients.

METHODS

Data on psychiatric inpatients admitted from 2002 to 2013 were extracted from the psychiatric inpatient registry of the National Health Insurance and merged with information from the Cause of Death data by means of unique identified numbers. Suicides occurring during admission and within 90 days after discharge were defined as inpatient and postdischarge suicides, respectively. Calendar year was fitted as a continuous variable in multivariate Poisson regression models to evaluate these rates over time. The analyses were adjusted for sex, age, primary psychiatric diagnosis, and number of admissions in the preceding year.

RESULTS

The overall inpatient suicide rate was very low (81 per 100,000 person-years). It decreased significantly from 146 to 74 per 100,000 person-years over the study period. This fall was observed among both genders and across all psychiatric diagnoses. The postdischarge suicide rate was comparatively high (1108 per 100,000 person-years) and did not show statistically significant change over the study period.

CONCLUSIONS

Our results suggest that efforts to increase public awareness of mental disorders and efficient utilization of psychiatric inpatient care are essential for suicide prevention despite the comparatively high bed capacity. The discharge plans of inpatients should be bridged with population suicide prevention programs for continuity of care after discharge.

The role of prediction in suicide prevention

It is widely believed that suicide prevention involves the consideration of risk and protective factors and related interventions. Preventative interventions can be classified as “universal” (targeting whole populations), “selective” (targeting higher-risk groups), and “indicated” (protecting individuals). This review explores the range of preventative measures that might be used commensurately with different types of suicide prediction. The author concludes that the best prospects for suicide prevention lie in universal prevention strategies. While risk assessments do generate some information about future suicide, suicide risk categorization results in an unacceptably high false positive rate, misses many fatalities, and therefore, is unable to usefully guide prevention strategies. The assessment of suicidal patients should focus on contemporaneous factors and the needs of the patient, rather than probabilistic notions of suicide risk.

Recurrence and mortality 1 year after hospital admission for non-fatal self-harm: a nationwide population-based study

AIMS

A large number of people present each day at hospitals for non-fatal deliberate self-harm (DSH). Examination of the short-term risk of non-fatal recurrence and mortality at the national level is of major importance for both individual medical decision-making and global organisation of care.

METHODS

Following the almost exhaustive linkage (96%) of two national registries in France covering 45 million inhabitants (i.e. 70% of the whole population), information about hospitalisation for DSH in 2008-2009 and vital status at 1 year was obtained. Individuals who died during the index hospital stay were excluded from analyses.

RESULTS

Over 2 years, 136,451 individuals were hospitalised in medicine or surgery for DSH. The sample comprised 62.8% women, median age 38 in both genders, with two peaks at 16 and 44 years in women, and one peak at 37 years in men. The method used for DSH was drug overdose in 82.1% of cases. Admission to an intensive care unit occurred in 12.9%. Following index hospitalisation, 71.3% returned home and 23.7% were transferred to a psychiatric inpatient care unit. DSH recurrence during the following year occurred in 12.4% of the sample, within the first 6 months in 75.2%, and only once in 74.6%. At 1 year, 2.6% of the sample had died. The overall standardised mortality ratio was 7.5 but reached more than 20 in young adults. The causes were natural causes (35.7%), suicide (34.4%), unspecified cause (17.5%) and accident (12.4%). Most (62.9%) deaths by suicide occurred within the first 6 months following index DSH. Violent means (i.e. not drug overdose) were used in 70% of suicide cases. Concordance between means used for index DSH and for suicide was low (30% overall), except for drug overdose. Main suicide risk factors were older age, being male, use of a violent means at index DSH, index admission to an intensive care unit, a transfer to another medical department or to a psychiatric inpatient unit, and recurrence of DSH. However, these factors had low positive predictive values individually (below 2%).

CONCLUSIONS

Non-fatal DSH represent frequent events with a significant risk of short-term recurrence and death from various causes. The first 6 months following hospital discharge appear to be a critical period. Specific short-term aftercare programs targeting all people with a DSH episode have to be developed, along other suicide prevention strategies.

Suicide and all-cause mortality following routine hospital management of self-harm: Propensity score analysis using multicentre cohort data

BACKGROUND

Observational studies are suited to examining links between the routine hospital management of self-harm and future suicide and all-cause mortality due to their large scale. However, care must be taken when attempting to infer causal associations in non-experimental settings.

METHODS

Data from the Multicentre Study of Self-Harm in England were used to examine associations between four types of hospital management (specialist psychosocial assessment, general hospital admission, psychiatric outpatient referral and psychiatric admission) following self-harm and risks of suicide and all-cause mortality in the subsequent 12 months. Missing data were handled by multiple imputation and propensity score (PS) methods were used to address observed differences between patients at baseline. Unadjusted, PS stratified and PS matched risk ratios (RRs) were calculated.

RESULTS

The PSs balanced the majority of baseline differences between treatment groups. Unadjusted RRs showed that all four treatment types were associated with either increased risks or no change in risks of suicide and all-cause mortality within a year. None of the four types of hospital management were associated with lowered risks of suicide or all-cause mortality following propensity score stratification (psychosocial assessment and medical admission) and propensity score matching (psychiatric outpatient referral and psychiatric admission), though there was no longer an increased risk among people admitted to a psychiatric bed. Individuals who self-cut were at an increased risk of death from any cause following psychosocial assessment and medical admission. Medical admission appeared to be associated with reduced risk of suicide in individuals already receiving outpatient or GP treatment for a psychiatric disorder.

CONCLUSIONS

More intensive forms of hospital management following self-harm appeared to be appropriately allocated to individuals with highest risks of suicide and all-cause mortality. PS adjustment appeared to attenuate only some of the observed increased risks, suggesting that either differences between treatment groups remained, or that some treatments had little impact on reducing subsequent suicide or all-cause mortality risk. These findings are in contrast to some previous studies that have suggested psychosocial assessment by a mental health specialist reduces risk of repeat self-harm. Future observational self-harm studies should consider increasing the number of potential confounding variables collected.

Attention-deficit/hyperactivity disorder symptoms and suicidal behavior in adult psychiatric outpatients

AIM

We aimed to examine the association between attention-deficit/hyperactivity disorder (ADHD) symptoms and suicidal behavior in psychiatric outpatients and whether this association differs among patients with different psychiatric disorders.

METHODS

Cross-sectional data came from the Japan Prevalence Study of Adult ADHD at Psychiatric Outpatient Care, which included psychiatric outpatients aged 18-65 years recruited from one university hospital and three general psychiatric outpatient clinics in Kitakyushu City, Fukuoka, Japan from April 2014 to January 2015 (N = 864). The Adult ADHD Self-Report Scale (ASRS) Screener was used to collect information on ADHD symptoms. Reports of current and lifetime suicidal behavior were also obtained. A multivariable Poisson regression analysis was used to examine the association between ADHD symptoms and suicidal behavior.

RESULTS

After adjusting for covariates there was a strong association between possible ADHD (ASRS ≥14) and suicidal behavior with prevalence ratios ranging from 1.17 (lifetime suicidal ideation) to 1.59 (lifetime suicide attempt) and 2.36 (current suicidal ideation). When ASRS strata were used, there was a dose-response association between increasing ADHD symptoms and suicidal ideation and suicide attempts. Analyses of individual ICD-10 psychiatric disorders showed that associations varied across disorders and that for anxiety disorder, ADHD symptoms were significantly linked to all forms of suicidal behavior.

CONCLUSION

ADHD symptom severity is associated with an increased risk for suicidal behavior in general psychiatric outpatients. As ADHD symptoms are common among adult psychiatric outpatients, detecting and treating ADHD in this population may be important for preventing suicidal behavior.

Psychiatric hospitalisation and the risk of suicide

The association between current or recent psychiatric hospitalisation and increased suicide risk is well described. This relationship is generally assumed to be due to the selection of people at increased risk of suicide for psychiatric admission and subsequent failure of protection from suicide once admitted. Here, Matthew Large and Nav Kapur debate whether or not admission to hospital also selects for vulnerability to certain harmful aspects of hospitalisation and whether the increased rate of suicide in current and recently discharged psychiatric patients is, in fact, due to psychiatric hospitalisation itself.Declaration of interestM.M.L. has provided expert testimony in legal proceedings following in-patient suicide.

Suicide prevention in mental health services: A qualitative analysis of coroners' reports

Suicide is a major concern for mental health nurses because of its clear correlation with mental illness. In New Zealand, coroners investigate all deaths that appear to be a result of suicide, and provide reports to mental health services (MHS). The aim of the present study was to investigate coronial recommendations to MHS in relation to suicide prevention and to examine clinical and family responses to these. The present study was a three-phase design: (i) analysis of coroners' recommendations related to suicide in MHS; (ii) interviews with clinicians for their response to the recommendations; and (iii) interviews with individuals working with families of consumers of MHS for their responses in relation to family-related recommendations. A qualitative content analysis was conducted on the recommendations from coroners, the interviews with clinical leaders, and the focus group for family workers. Coroners recommended that MHS should implement suicide-prevention strategies that would facilitate improved communication, risk containment, service delivery, and family involvement. Clinicians agreed with most recommendations, apart from those related to risk containment. Family workers endorsed the coronial perspective that family inclusion in MHS was suboptimal. Coroners, MHS, and mental health nurses need to consider the latest clinical evidence for suicide prevention. However, given the complexity of factors that influence suicide, it is important to be realistic about MHS role in preventing suicide, but ensure that MHS provide interventions for which there is evidence, including facilitating family participation and providing access to psychotherapies.

Counseling on Access to Lethal Means (CALM): An Evaluation of a Suicide Prevention Means Restriction Training Program for Mental Health Providers

This paper evaluates the effectiveness of the Counseling on Access to Lethal Means (CALM) suicide prevention program. CALM trains mental health providers how to counsel suicidal individuals and those who support them on mean restriction during times of crisis. Pre/post/3-month follow-up assessments measured knowledge of lethal means, confidence and comfort in discussing means restriction (self-efficacy), and future intentions to counsel clients on means restriction. Change in the number of clients receiving lethal means counseling was also assessed. All constructs increased significantly at posttest. Confidence and counseling intentions were sustained at follow-up and significantly more clients received means counseling in the 3 months following the CALM training. Knowledge and comfort levels decreased at follow-up but not to pre-training levels. CALM is effective at increasing mental health professionals' comfort, knowledge, and frequency of talking about means restriction with clients. an effective means restriction training program. A template to assess clients for suicidality and lethal means access and booster sessions are recommended to further sustain effects.

Suicide mortality among male veterans discharged from Veterans Health Administration acute psychiatric units from 2005 to 2010

PURPOSE

The purpose of this study was to calculate suicide rates and identify correlates of risk in the year following discharge from acute Veterans Health Administration psychiatric inpatient units among male veterans discharged from 2005 to 2010 (fiscal years).

METHODS

Suicide rates and standardized mortality ratios were calculated. Descriptive analyses were used to describe suicides and non-suicides and provide base rates for interpretation, and unadjusted and adjusted proportional hazard models were used to identify correlates of suicide.

RESULTS

From 2005 to 2010, 929 male veterans died by suicide in the year after discharge and the suicide rate was 297/100,000 person-years (py). The suicide rate significantly increased from 234/100,000 py (95% CI = 193-282) in 2005 to 340/100,000 py (95% CI = 292-393) in 2008, after which it plateaued. Living in a rural setting, HR (95% CI) = 1.20 (1.05, 1.36), and being diagnosed with a mood disorder such as major depression, HR (95% CI) = 1.60 (1.36, 1.87), or other anxiety disorder, HR (95% CI) = 1.52 (1.24, 1.87), were associated with increased risk for suicide.

CONCLUSIONS

Among male veterans, the suicide rate in the year after discharge from acute psychiatric hospitalization increased from 2005 to 2008, after which it plateaued. Prevention efforts should target psychiatrically hospitalized veterans who live in rural settings and/or are diagnosed with mood or other anxiety disorders.

Suicide Rates After Discharge From Psychiatric Facilities: A Systematic Review and Meta-analysis

Importance

High rates of suicide after psychiatric hospitalization are reported in many studies, yet the magnitude of the increases and the factors underlying them remain unclear.

Objectives

To quantify the rates of suicide after discharge from psychiatric facilities and examine what moderates those rates.

Data Sources

English-language, peer-reviewed publications published from January 1, 1946, to May 1, 2016, were located using MEDLINE, PsychINFO, and EMBASE with the search terms ((suicid*).ti AND (hospital or discharg* OR inpatient or in-patient OR admit*).ab and ((mortality OR outcome* OR death*) AND (psych* OR mental*)).ti AND (admit* OR admis* or hospital* OR inpatient* OR in-patient* OR discharg*).ab. Hand searching was also done.

Study Selection

Studies reporting the number of suicides among patients discharged from psychiatric facilities and the number of exposed person-years and studies from which these data could be calculated.

Data Extraction and Synthesis

The meta-analysis adhered to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. A random-effects model was used to calculate a pooled estimate of postdischarge suicides per 100 000 person-years.

Main Outcomes and Measures

The suicide rate after discharge from psychiatric facilities was the main outcome, and the association between the duration of follow-up and the year of the sampling were the main a priori moderators.

Results

A total of 100 studies reported 183 patient samples (50 samples of females, 49 of males, and 84 of mixed sex; 129 of adults or unspecified patients, 20 of adolescents, 19 of older patients, and 15 from long-term or forensic discharge facilities), including a total of 17 857 suicides during 4 725 445 person-years. The pooled estimate postdischarge suicide rate was 484 suicides per 100 000 person-years (95% CI, 422-555 suicides per 100 000 person-years; prediction interval, 89-2641), with high between-sample heterogeneity (I2 = 98%). The suicide rate was highest within 3 months after discharge (1132; 95% CI, 874-1467) and among patients admitted with suicidal ideas or behaviors (2078; 95% CI, 1512-2856). Pooled suicide rates per 100 000 patients-years were 654 for studies with follow-up periods of 3 months to 1 year, 494 for studies with follow-up periods of 1 to 5 years, 366 for studies with follow-up periods of 5 to 10 years, and 277 for studies with follow-up periods longer than 10 years. Suicide rates were higher among samples collected in the periods 1995-2004 (656; 95% CI, 518-831) and 2005-2016 (672; 95% CI, 428-1055) than in earlier samples.

Conclusions and Relevance

The immediate postdischarge period is a time of marked risk, but rates of suicide remain high for many years after discharge. Patients admitted because of suicidal ideas or behaviors and those in the first months after discharge should be a particular focus of concern. Previously admitted patients should be able to access long-term care and assistance.

Should compulsory admission to hospital be part of suicide prevention strategies?

The World Health Organization report Preventing Suicide: A Global Imperative provides governments with guidance for comprehensive suicide prevention strategies. However, it does not mention the role that compulsory admission to hospital of psychiatric patients should have in policies for suicide prevention. This was a missed opportunity for international discussion and guidance about a measure that, although widely used, is becoming increasingly controversial in light of the existing evidence and human rights norms.

In-patient suicide: selection of people at risk, failure of protection and the possibility of causation

BACKGROUND

Being a current psychiatric in-patient is one of the strongest statistical risk factors for suicide. It is usually assumed that this strong association is not causal but is a result of the combination of the selection of high-risk patients for admission and the imperfect protection from suicide afforded by psychiatric wards. Logically, a third factor, which is causal, might play a role in the association. It has recently been suggested that adverse experiences in psychiatric units such as trauma, stigma and loss of social role might precipitate some in-patient suicides.

AIMS

To consider whether there is a causal association between psychiatric hospitalisation and suicide.

METHOD

We used the framework of Austin Bradford Hill's criteria for assessing causality in epidemiology to consider the possibility that psychiatric hospitalisation might causally contribute to the extent and variation in in-patient suicide rates.

RESULTS

The association between psychiatric hospitalisation and suicide clearly meets five of the nine Hill's criteria (strength of association, consistency, plausibility, coherence and analogy) and partially meets three of the remaining four criteria (gradient of exposure, temporality and experimental evidence).

CONCLUSIONS

Admission to hospital itself might play a causal role in a proportion of in-patient suicides. The safety of being in hospital with respect to suicide could be examined with a large-scale randomised controlled trial (RCT). In the absence of an RCT, the possibility of a causal role provides further impetus to calls to make care in the community more available and psychiatric hospitals more acceptable to patients.

Risk of suicide according to the level of psychiatric contact in the older people: Analysis of national health insurance databases in Taiwan

PURPOSE

Suicide in the older people is a serious problem worldwide; however the effect of psychiatric contact on the risk of suicide has not been fully explored. The aim of this study was to investigate the relationship between psychiatric contact and suicide in the older people in Taiwan.

METHODS

A population-based database was used in this national case-control study. Propensity score matching was used to match older people who did and did not commit suicide from 2010 to 2012 by calendar year, gender, age, and area of residence. The level of psychiatric contact in the preceding year was classified as "no psychiatric contact," "only outpatient psychiatric contact," "psychiatric emergency room contact," or "psychiatric hospital admission". Conditional logistic regression analysis was used to assess associations between variables and the risk of suicide.

RESULTS

A total of 2528 older people committed suicide from 2010 to 2012, with a crude suicide mortality rate of 3.37/10,000. Compared to those who had no psychiatric contact in the preceding year, the adjusted odds ratios of suicide were 10.15 (95% CI=5.8-17.7) for those who had psychiatric emergency room contact, 6.57 (95% CI=3.7-11.6) for those who had psychiatric hospital admissions, and 3.64 (95% CI=3.0-4.4) for those with only outpatient psychiatric contact. The risk of suicide was higher in those who had depression (OR=3.49, 95% CI=2.2-5.4) and bipolar disorder (OR=1.98, 95% CI=1.1-3.6). Patients with cancer were associated with suicide (OR=8.96, 95% CI=5.6-14.4).

CONCLUSIONS

The positive association with suicide and the level of psychiatric contact in the preceding year in older people indicated that the health personnel need to do a better job in determining possible risk for older people who had psychiatric contact, especially in emergency visit or psychiatric admission. A systematic approach to quality improvement in these settings is both available and necessary. Careful discharge planning and safe transitions of care to outpatient services are required for suicide prevention of high-risk patients after discharge.

Risk Estimates and Risk Factors Related to Psychiatric Inpatient Suicide-An Overview

People with mental illness have an increased risk of suicide. The aim of this paper is to provide an overview of suicide risk estimates among psychiatric inpatients based on the body of evidence found in scientific peer-reviewed literature; primarily focusing on the relative risks, rates, time trends, and socio-demographic and clinical risk factors of suicide in psychiatric inpatients. Psychiatric inpatients have a very high risk of suicide relative to the background population, but it remains challenging for clinicians to identify those patients that are most likely to die from suicide during admission. Most studies are based on low power, thus compromising quality and generalisability. The few studies with sufficient statistical power mainly identified non-modifiable risk predictors such as male gender, diagnosis, or recent deliberate self-harm. Also, the predictive value of these predictors is low. It would be of great benefit if future studies would be based on large samples while focusing on modifiable predictors over the course of an admission, such as hopelessness, depressive symptoms, and family/social situations. This would improve our chances of developing better risk assessment tools.
