Suicide in Older Adults With and Without Known Mental Illness: Results From the National Violent Death Reporting System, 2003-2016

Bibliometric and visual analysis of suicide in aged people over the past 20 years

Background

The rapid aging of the global population presents pressing public health challenges, notably an increase in suicide rates among older adults. Despite this critical issue, there is a scarcity of comprehensive assessments regarding the existing literature on suicide within this demographic. This study seeks to employ bibliometric analysis and knowledge mapping to elucidate prevailing research trends and the overall status of this field.

Methods

We performed a comprehensive computer-based search of the Web of Science Core Collection to identify relevant articles and reviews concerning suicide in the elderly. A bibliometric analysis was conducted, examining various aspects including countries or regions, institutions, authors, journals, keywords, and references. This analysis utilized tools such as CiteSpace, VOSViewer, Pajek, and Excel 365 to facilitate a thorough assessment.

Results

The analysis covered 1,116 publications from 2005 to 2024. The annual number of publications showed a fluctuating upward trend, with notable decreases in 2007, 2012, 2015, 2017, and 2022, and increases in 2009, 2013, 2016, and 2019, peaking at 121 in 2021, with citations reaching 4,741 in 2022, but declining since then. The United States stands out as the most productive and influential country in the field, boasting the highest number of publications and citations. The country is home to institutions leading in both publication and citation metrics. Prominent authors contributing significantly to this domain include Conwell Yeates, Van Orden Kimberly A., and Waern Margda. Key journals disseminating crucial research are the Journal of Affective Disorders, American Journal of Geriatric Psychiatry, and Lancet. Frequent keywords in this field encompass depression, suicidal ideation, suicide, older-adults, risk, risk factors, prevalence, older adults, ideation, behavior, health, mental health, life, age, people, prevention, symptoms, scale, population, and elderly. The contemporary research emphasis is primarily on identifying, treating, and preventing the suicide risk associated with depression in older adults.

Conclusions

This study highlights the growing research focus on suicide in older adults, particularly related to depression and the identification, treatment, and prevention of suicide risk. The findings underscore the need for targeted prevention strategies and further investigation in this critical public health area.

Prospective comparison of risk factors for firearm suicide and non-firearm suicide in a large population-based cohort of current and former US service members: findings from the Millennium Cohort Study

Background

Suicide is a leading cause of death among service members and veterans. Among suicide methods, firearms are the most lethal and commonly used method among military populations. Limited research has compared risk factors for the various suicide methods. This study evaluated and compared risk factors for firearm versus non-firearm suicides using data from the Millennium Cohort Study, a large longitudinal military cohort.

Methods

Using a competing risk approach, we identified factors associated with each suicide method. Risk factors included demographics, mental health diagnoses, mental health symptoms, military-specific characteristics, health behaviors, and psychosocial factors. Cause of death was assessed from July 1, 2001, through December 31, 2018.

Findings

Among 201,565 eligible participants with a mean [SD] age of 29.0 [58.1] years, there were 139,789 (69.3%) male, 61,776 (30.7%) female, 15,927 (7.9%) Hispanic, 24,667 (12.3%) non-Hispanic Black, 14,138 (7.0%) Asian, Pacific Islander, American Indian or Multiracial, and 146,736 (72.8%) non-Hispanic White participants. During the study period, 330 died by firearm suicide and 168 died by non-firearm suicide. Overall, effect estimates for risk factors were similar across both methods of suicide. After adjustment, men (HR: 3.69, 95% CI: 2.59, 5.24) and those who screened positive for depression (HR: 1.97, 95% CI: 1.36, 2.87) had an elevated risk for firearm suicide. In contrast, those who self-reported a history of bipolar diagnosis (HR: 3.40, 95% CI: 1.76, 6.55) had significantly increased risk for non-firearm suicide.

Interpretation

Findings suggest that prevention and intervention strategies overall may not need to be differentiated by specific demographic, military, or health factors. Targeted interventions that consider sex and mental health screens might have relative utility in preventing firearm related suicide risk compared with non-firearm suicide.

Risk factors and methods in suicides of elderly patients connected to mental health services from 1999-2024

Introduction

Suicide prevention is an important aspect of psychiatric care, with older men being a population identified at especially high suicide risk and a recent increase in suicides among older women.

Methods

Using data collected by the region's quality assurance team, we examined all suicide deaths occurring between March 1999 and February 2024 in patients aged 60 years or older who were connected to the region's Addiction and Mental Health Program at the time of death. Data were analyzed to describe which factors were most commonly identified in suicides in older adults receiving mental healthcare. We also compared male and female cases to determine whether certain factors were more commonly observed in one gender.

Results

We identified 48 cases of suicide occurring in patients aged 60 or over. 60% of suicides occurred in males. Overdose and hanging were the most common suicide methods used, and all suicides occurring on inpatient units occurred via hanging. Depression was the most common diagnosis, and was diagnosed more frequently in suicides of female older adults. A greater proportion of suicides in older women were associated with previous history of suicide attempts.

Discussion

Our findings support many current best practices for suicide prevention in psychiatric care, including minimizing ligatures and anchor points on inpatient settings, assessing for and limiting access to means in individuals at-risk, and assessing suicide risk in hospitalized patients prior to passes and discharge. Recognition and treatment of depression remain important aspects in the treatment of older adults to prevent suicide.

The association among thriving in life, quality of life, and suicidal ideation in Chinese urban older adults: the moderating effects of attitude toward own aging

BACKGROUND

As the global trend of population aging intensifies, the health and well-being of the older population has gradually become a focus of attention for the global community. This study assessed the status of thriving in life among Chinese urban older adults and identified its relationship with attitude toward own aging and quality of life (QoL). It also tested whether attitude toward own aging moderates the association between thriving in life and Qol or between thriving in life and suicidal ideation.

METHODS

Primary data were collected through a cross-sectional survey among urban older adults from three provinces in China. They were invited to complete an anonymous survey using face-to-face interviews from December 2019 to January 2020. Data from 764 older adults were analyzed.

RESULTS

Approximately 44.39% of participants reported positive responses toward the four domains of thriving in life. Thriving in life and attitude toward own aging had a significant association with QoL. Thriving in life was a protective factor for suicidal ideation for older adults. Moreover, attitude toward own aging moderated the association between thriving in life and QoL and that between thriving in life and suicidal ideation.

CONCLUSIONS

Chinese urban older adults were reportedly thriving in life, which contributed to increased QoL and reduced suicidal ideation. Notably, the study revealed that more positive attitudes towards own aging were associated with higher levels of thriving in life, better QoL, and reduced suicidal ideation. Targeted interventions for older adults should be devised to promote thriving in life and prevent negative attitudes of older people towards their own aging, further raising QoL and reducing suicidal ideation.

Depression in older women who died by suicide: associations with other suicide contributors and suicide methods

Suicides among older women have received little research attention. In this study based on the 2017-2019 National Violent Death Reporting System data, we examined the prevalence of depression in older female suicide decedents (N = 3,061), associations between depression and other suicide precipitants, and the associations between suicide methods and depression. Descriptive statistics and generalized linear models (GLM) for a Poisson distribution with a log link were used to examine the research questions. Of the decedents, 15.0% had depressed mood without a reported diagnosis and 41.8% had a depression diagnosis. Nearly one-half of the decedents with reported depression were receiving mental health/substance use treatment at the time of injury. The likelihood of depression was lower among those who were age 85 and older compared to those were age 65-74, but higher among those who had anxiety disorder (IRR = 1.50, 95% CI = 1.33-1.69), history of suicidal ideation (IRR = 1.22, 95% CI = 1.10-1.35), history of suicide attempt (IRR = 1.27, 95% CI = 1.14-1.41), and bereavement problems (IRR = 1.45, 95% CI = 1.27-1.65). Those who had depression were less likely to have used firearms (IRR = 0.85, 95% CI = 0.75-0.97) but more likely to have used hanging/suffocation (IRR = 1.37, 95% CI = 1.13-1.67). The findings show that gun ownership was likely an important factor for firearm use. The high prevalence of depressed mood and/or depression diagnosis among older female suicide decedents at the time of their fatal injury underscores the importance of assessing depression and providing evidence-based depression treatment as an essential suicide prevention approach.

Comorbidity profiles in older patients last seen by mental health prior to suicide attempt

OBJECTIVES

Suicide in late life is a public health concern. Determining profiles of psychiatric/medical comorbidity in those who attempt while engaged in mental health services may assist with prevention. We identified comorbidity profiles and their association with utilization, means, and fatality in a national sample who attempted suicide.

METHODS

Using latent class analysis, all patients aged ≥ 65 from the Department of Veterans Affairs (VA) healthcare services (2012-2018) last seen in mental health prior to suicide attempt were included. Diagnoses and attempt data were obtained from VA and Center for Medicare & Medicaid Services, VA Suicide Prevention Applications Network, and VA National Mortality Data Repository.

RESULTS

2,269 patients were clustered into three profiles, all with high probability of depression. Profiles included minimal comorbidity (50.4%), high medical comorbidity (28.6%), and high (psychiatric/medical) comorbidity (21.0%). Over half (61.7%) attempted suicide within one week of their visit. The class with highest comorbidity had lowest proportion of fatal attempts, while minimal comorbidity class had highest proportion.

CONCLUSIONS

Older patients last seen in mental health prior to suicide attempt were characterized by depression and varying additional comorbidity and attempt-related factors. Findings have implications for risk assessment and intervention in mental health settings, beyond depression.

Suicide and Hospice Caregivers: A Case Study

In 2020, hospices supported 1.72 million Medicare patients and their caregivers. The end-of-life experience can be difficult for caregivers and many experience anxiety, depression, and suicidality. Little literature has explored the role of hospice social workers in addressing and treating caregivers' suicidal thoughts and behaviors. This paper will explore the topic of hospice caregiver suicide, using a case study to illustrate relevant issues, practices, and needs. Implications for hospice social work practice are included.

Firearm Safety for Patients Diagnosed With Cancer-A Role in Suicide Prevention

This Viewpoint discusses firearm safety guidelines among patients diagnosed with cancer and at a higher risk of suicide.

Disclosure of suicidal ideation and behaviours: A systematic review and meta-analysis of prevalence

Disclosure of suicidal ideation and behaviours, defined as thoughts, plans, or attempts, to other people provides opportunity for intervention and prevention. This study is the first to meta-analyze all available studies to estimate the prevalence of disclosure, to whom people disclose, and examine factors that influence disclosure. Databases were searched for studies reporting samples of people who had experienced suicidal ideation or behaviours (including those who had died by suicide) and whether they had disclosed this. Almost 100 studies (k = 94, N participants = 1,044,629) were included in the overall prevalance analysis. The results showed less than half of people disclosed suicidal ideation or behaviour: 45.9% (95%CI 41.9-49.9%, PI 12.3-81.8%; k = 94). High heterogeneity, common to prevalence studies, was found (Q[93] = 130,584, p < .001; I² = 99.9%). No publication bias was detected. Removing outliers did not change the prevalence estimate, but provided tighter prediction intervals: 45.6% (95%CI 43.4-47.9%, PI 35.8-55.7%; k = 33). Disclosure was related to higher prevalence of psychiatric disorders, female gender, and a longer timeframe of suicidal ideation or behaviour. Prevalence of disclosure was lower among people who died by suicide, relative to community samples, and lower when reported verbally rather than written online. Disclosure, and proportions of disclosures, to family members, was numerically higher than to friends or professionals, but could not be directly compared. In conclusion, between 50 and 60% of people do not disclose their suicidal ideation and behaviours to other people, and therefore remain unidentified and potentially untreated.

Suicidal intent disclosure among adult suicide decedents: Four age group comparisons

Research on who does/does not disclose suicidal intent (SI) and related factors has important implications for suicide risk management. In this paper based on the 2017-2019 National Violent Death Reporting System, we compared four age groups (18-24, 25-44, 45-64, and 65+ years) of suicide decedents with respect to associations between SI disclosure and (1) suicide contributing/precipitating factors, and (2) suicide means. The results shows that those age 18-44 were more likely to disclose SI than those age> =45, especially among those with relationship problems. Physical health problems and death/suicide of family/friend increased the likelihood of SI disclosure in the 65+ age group.

Intent disclosure in late-life suicide: Age group differences in correlates and associations with suicide means

Age-adjusted suicide rates declined from 2018 to 2020. However, suicide rates among older adults, particularly males 75 and older, have continued to rise, and the evidence base for effective interventions to prevent suicide in late life remains limited. One strategy to prevent older adults' suicidal behavior is to intervene when they reveal suicide intent. Previous research found that a significant proportion of older suicide decedents disclosed their suicide intent close to the fatal incident. In this study, based on the 2017-2019 United States National Violent Death Reporting System (NVDRS) data, we examined: (1) correlates of intent disclosure among three age groups (65-74, 75-84, and 85+) of older suicide decedents (N = 17,917; 14,856 men and 3,061 women); and (2) associations of suicide means with intent disclosure and suicide contributing factors. The results show that 19.9% of all suicide decedents aged 65+ (18.7%, 21.0%, and 22.0% in the 65-74, 75-84, and 85+ age groups, respectively) disclosed their suicide intent to their partner, family/friends, and healthcare providers within a month of their death. Multivariable analyses using generalized linear models for a Poisson distribution with a log link showed that physical and mental health, substance misuse, addiction problems, and relationship/other life stressors were associated with a higher likelihood of intent disclosure in the 65-74 and 75-84 age groups. However, only physical health problems were associated with a higher likelihood of intent disclosure among those aged 85 and older. Intent disclosure was not associated with using firearms and poisoning as suicide means but with a lower likelihood of hanging or suffocation. Mental health and substance misuse problems were associated with higher odds of hanging or suffocation and poisoning, and physical health problems and male sex in the 85+ age group were associated with higher odds of firearm use. Suicide prevention strategies for those who have disclosed their suicide intent or are at risk of suicidal behavior should include more patient-centered comfort and palliative care, mental health/substance misuse/addiction treatment, and restriction of access to potential suicide means. More research on older adults who disclose suicide intent and late-life suicide prevention strategies is needed.

What distinguishes high and low-lethality suicide attempts in older adults? A systematic review and meta-analysis

Those making suicide attempts with highly lethal medical consequences are arguably the best proxy for those who die by suicide and represent a qualitatively different population from those making lower lethality attempts. Different factors influence the likelihood of a suicide attempt occurring and the lethality of that attempt. Both are important dimensions of risk. Older adults represent a distinct group in suicide research with unique risk factors that influence the lethality of their suicide attempts. This systematic review and meta-analysis summarises factors distinguishing those making high and low-lethality suicide attempts in older adulthood. Databases PsycINFO, PubMed (MEDLINE), Embase and CINAHL were systematically searched with seven of 1182 unique records included. Random effects meta-analyses were conducted on 18 variables in addition to a narrative synthesis regarding executive function. Only increased suicidal intent and planning meaningfully distinguished high from low-lethality attempters in meta-analyses. A large effect size was additionally observed for white ethnicity. Diminished alcohol use disorder prevalence and depression severity, and greater cognitive impairment, may be associated with high lethality attempters but further research is needed. Age and gender were not associated with lethality, contrary to adult populations. A narrative synthesis of studies exploring differences in executive functioning suggested high-lethality attempters were less likely to impulsively act on suicidal urges, allowing them to better plan suicide attempts that are more lethal, and are less likely to alter suicidal plans. Key limitations were that meta-analyses were underpowered to detect small effect sizes, and samples were largely white and limited to the USA.

Impact of COVID-19 on mental health and emotional well-being of older adults

Older adults faced unique challenges in the pandemic due to their increased vulnerability to coronavirus disease 2019 (COVID-19) and its complications. Pandemic-related restrictions such as physical distancing, stay-at-home orders, lock-down, and mandatory face cover affected older adults in unique ways. Additionally, older adults experienced psychosocial concerns related to discrimination based on ageism and emotional distress from exposure to conflicting messages in the media. They experienced several forms of loss and associated grief and survivor guilt. Pandemic added to their loneliness and social isolation. Furthermore, older adults experienced the fear and anxiety related to COVID and the fear of contracting the disease and dying from it. Pandemic experience included events potential to generate the desire and capability for suicide. Several studies report varying symptoms such as loneliness, anxiety, and depression among older adults during the pandemic. However, during the initial months of the pandemic, there were reports on coping and resilience among this population. The impact of COVID-19 on older adults’ mental health may have long-term implications. This narrative review examines the impact of COVID-19 on older adults’ mental health and psychosocial wellbeing. Additionally, the review highlights various factors that affected their psychosocial wellbeing during the COVID-19 pandemic.

Comparing warning signs of suicide between suicide decedents with depression and those non-diagnosed psychiatric disorders

OBJECTIVE

Early recognition of a high-risk group impending suicide is important. We aimed to compare warning signs depending on the nature of the psychiatric disorder and whether it was a documented diagnosis.

METHODS

Data of suicide decedents were collected from police records from 2013 to 2017. We evaluate psychiatric symptoms and warning signs in three aspects (language, behavior, and affect) using the Korea-Psychological Autopsy Checklist for Police Records (K-PAC-PR).

RESULTS

A total of 13,265 suicide decedents were recruited for this study. Of them, 66.9% of females and 46.7% of males diagnosed psychiatric disorders, with depressive disorder being the most common one. Warning signs were observed in 93.0% of suicide decedents. They were observed more in those who were diagnosed with psychiatric disorders, especially in those with a depressive disorder. "Talking about dying or suicide" was the most common warning sign in all groups, and "apathetic behavior" was the most related warning sign for depressive disorder. Especially for "talking about dying or suicide," the proportion of observed "within a week" was high, making it valuable as a warning sign.

CONCLUSION

Warning signs were commonly found in suicide decedents regardless of gender. They were more common among the decedents diagnosed with psychiatric disorders, especially among those with a depressive disorder.

Factors Associated With 7-Day Follow-Up Outpatient Mental Healthcare in Older Adults Hospitalized for Suicidal Ideation, Suicide Attempt, and Self-Harm

OBJECTIVE

Older adults are one of the fastest growing age groups seeking emergency care for suicidal ideation and self-harm. Timely follow-up outpatient mental healthcare is important to suicide prevention, yet little is known about predictors of care continuity following hospital discharge. This study identified patient-, hospital-, and regional-level factors associated with 7-day follow-up outpatient mental healthcare in suicidal older adults.

METHODS

Retrospective cohort analysis using 2015 Medicare data for adults aged ≥65 years hospitalized for suicidal ideation, suicide attempt, or deliberate self-harm (n = 27,257) linked with the American Hospital Association survey and Area Health Resource File. Rates and adjusted risk ratios stratified by patient, hospital, and regional variables were assessed for 7-day follow-up outpatient mental healthcare.

RESULTS

Overall, 30.3% of patients received follow-up mental healthcare within 7 days of discharge. However, follow-up rates were higher for patients with any mental healthcare within 30 days prehospitalization (43.7%) compared to patients with no recent mental healthcare (15.7%). Longer length of stay and care in psychiatric hospitals were associated with higher odds of follow-up. For patients with no mental healthcare in the 30 days prehospitalization, discharge from hospitals that were large, system-affiliated, academic medical centers, or provided hospitalist-based care were associated with lower odds of follow-up. Females were more likely to receive 7-day follow-up, whereas non-white patients were less likely to receive follow-up care.

CONCLUSION

Timely follow-up is influenced by multiple patient, hospital, and community characteristics. Findings highlight the need for quality improvement to promote successful transitions from inpatient to outpatient care.

People Who Die by Suicide Without Receiving Mental Health Services: A Systematic Review

Introduction

The majority of people who die by suicide have never seen a mental health professional or been diagnosed with a mental illness. To date, this majority group has largely been ignored, with most existing research focusing on predictors of suicide such as past suicide attempts. Identifying the characteristics of people who die by suicide without receiving services, often with a fatal first attempt, is crucial to reduce suicide rates through guiding improvements to service pathways and “just in time” interventions.

Methods

In this systematic review, PsycInfo, PubMed, CINAHL, and Web of Science were searched for peer-reviewed articles published from 1980 to 1st March 2021. Included studies examined predictors of non-receipt of formal mental health services among people who died by suicide. Data were extracted from published reports and the quality of included studies was assessed using a modified version of the Joanna Briggs Institute Checklist for Analytical Cross Sectional Studies. This review was registered with PROSPERO, CRD 42021226543.

Results

Sixty-seven studies met inclusion criteria, with sample sizes ranging from 39 to 193,152 individuals. Male sex, younger or older age, and rural location were consistently associated with non-receipt of mental health services. People not receiving mental health services were also less likely to have a psychiatric diagnosis, past suicidal behavior or contact with general health services, and more likely to use violent means of suicide. There was some evidence that minority ethnicity and psychosocial stressors were associated with service non-receipt.

Conclusion

People who die by suicide without receiving mental health services are likely to have diverse profiles, indicating the need for multifaceted approaches to effectively support people at risk of suicide. Identifying the needs and preferences of individuals who are at risk of suicide is crucial in developing new support pathways and services, and improving the quality of existing services.

Longitudinal Neurocognitive Effects of Combined Electroconvulsive Therapy (ECT) and Pharmacotherapy in Major Depressive Disorder in Older Adults: Phase 2 of the PRIDE Study

OBJECTIVE

There is limited information regarding neurocognitive outcomes of right unilateral ultrabrief pulse width electroconvulsive therapy (RUL-UB ECT) combined with pharmacotherapy in older adults with major depressive disorder. We report longitudinal neurocognitive outcomes from Phase 2 of the Prolonging Remission in Depressed Elderly (PRIDE) study.

METHOD

After achieving remission with RUL-UB ECT and venlafaxine, older adults (≥60 years old) were randomized to receive symptom-titrated, algorithm-based longitudinal ECT (STABLE) plus pharmacotherapy (venlafaxine and lithium) or pharmacotherapy-only. A comprehensive neuropsychological battery was administered at baseline and throughout the 6-month treatment period. Statistical significance was defined as a p-value of less than 0.05 (two-sided test).

RESULTS

With the exception of processing speed, there was statistically significant improvement across most neurocognitive measures from baseline to 6-month follow-up. There were no significant differences between the two treatment groups at 6 months on measures of psychomotor processing speed, autobiographical memory consistency, short-term and long-term verbal memory, phonemic fluency, inhibition, and complex visual scanning and cognitive flexibility.

CONCLUSION

To our knowledge, this is the first report of neurocognitive outcomes over a 6-month period of an acute course of RUL-UB ECT followed by one of 2 strategies to prolong remission in older adults with major depression. Neurocognitive outcome did not differ between STABLE plus pharmacotherapy versus pharmacotherapy alone over the 6-month continuation treatment phase. These findings support the safety of RUL-UB ECT in combination with pharmacotherapy in the prolonging of remission in late-life depression.

Therapeutic Risk Management and Firearm-related Lethal Means Safety

Safety planning to reduce suicide or other-directed violence risk involves efforts toward "making the environment safe," including working collaboratively with at-risk patients to encourage voluntary changes in their firearm storage decisions [ie, lethal means safety (LMS) counseling]. This column provides a conceptual framework and real-world evidence to support the delivery of LMS counseling to at-risk patients, as well as guidance on asking about firearm access and making individualized safety recommendations. It also reviews important elements related to documenting LMS discussions and legal considerations related to these conversations.

Association of mental disorders with firearm suicides: A systematic review with meta-analyses of observational studies in the United States

In the United States (US), 61% of all suicide cases may involve firearms, and some evidence suggests that mental disorders may play a role in suicide by firearm. We performed the first systematic review and meta-analyses to investigate: (i) whether mental disorders are associated with suicide by firearm, and (ii) whether the risk of using a firearm compared with alternative means is associated with higher levels of suicide in individuals with a mental disorder METHODS AND FINDINGS: We searched twelve databases from inception to the 24th of May 2020. We retrieved 22 observational studies conducted in the US. Random-effects meta-analyses showed individuals who had a diagnosis of a mental disorder had lower odds (odds ratios (OR)= 0.50, 95% CI: 0.36 to 0.69; I²=100 (95% CI: 87 to 100%), of dying by suicide with a firearm than those who did not have a diagnosis of a mental disorder. Secondary analysis showed that decedents who had a mental health diagnosis resulted in lower odds of dying by suicide by using firearms than using other means LIMITATIONS: Risk of bias revealed a heterogeneous and poor definition of mental disorders as well as lack of control for potential demographic confounding factors. In the meta-analyses, studies were combined in the same analytic sample as 77% of these studies did not specify the type of mental disorder CONCLUSION: While our results seem to suggest that having a mental disorder may not be consistently associated with the odds of dying by suicide using a firearm, the presence of substantial heterogeneity and high risk of bias precludes any firm conclusions.

Understanding Vulnerability to Late-Life Suicide

PURPOSE OF REVIEW

We review recent evidence on suicide among older adults, examine risk factors contributing to vulnerability to late-life suicide, and summarize possible interventions.

RECENT FINDINGS

We found a steadily increasing rate of late-life suicide in the USA in the past decade. Evidence supporting the integration of depression care managers into primary care for risk reduction is among the strongest to date. Pharmacologic and neuromodulation studies should be considered in geriatric depression complicated by suicidality. Broad societal campaigns about suicide education, as well as active outreach to psychiatric patients after discharge or a suicidal crisis, prevent suicidal behavior. Growing research supports an integrative multidisciplinary approach. Suicide is a complex and multifaceted behavior with numerous casual points for intervention. Access to deadly means, presence of depression, disease, disability, and social disconnection are factors that increase vulnerability. Quality geriatric care, regular screening in primary and emergency care settings, and a multidisciplinary approach are necessary to mitigate risk factors. The COVID-19 pandemic amplifies need for a more aggressive approach.

The Rising Tide of Elderly African-American Suicides: A Call for Action

Suicides are among the leading causes of death in elderly Americans. The problem is expected to grow with an aging population in the U.S. Suicides in African-American elderly are not well studied. This article enumerates the risk factors for suicidal behaviors in elderly African-Americans; presents an epidemiological assessment of suicides in elderly African-Americans from 2010 to 2018 with gender-specific differences, and explores public health considerations for helping to reduce the growing numbers of suicides in elderly African-Americans. Currently, there are very limited evidence-based interventions to reduce or prevent suicides in older African-Americans. This article also provides implications and recommendations for prevention practice and research that is needed to help alleviate suicides in older African-Americans.

Suicidal behaviour in older age: A systematic review of risk factors associated to suicide attempts and completed suicides

In older age, several observational studies investigated risk factors for suicide attempts/completed suicides; however, contrasting evidence came from population-based setting. In the present systematic review, we described through a narrative synthesis the significant associations existing among risk factors and suicide attempts/completed suicides in subjects aged >65 years. From the 39 population-based studies selected in six different databases until February 15, 2021, we analyzed the most frequent 28 risk factors for suicidal behaviour. The risk factors more associated to suicide attempts than other variables frequently related to suicidal behavior in older age were: depressive disorders, methods employed to self-harm (particularly poisoning), and psychotropic drug utilization followed by psychological factors and disability. Moreover, male sex, violent methods to self-harm, any psychiatric disorder (depression, anxiety and bipolar disorders), a poor medical condition, stressors/bereavement, and living alone appeared to be more significant for predicting completed suicides in late life. In older age, efforts for suicide prevention should be based on strategies to assess and treat psychiatric disorders along with psychological interventions, particularly in males.

Firearm Suicides in the Elderly: A Narrative Review and Call for Action

Firearm suicides are one of the leading causes of death for older Americans. The purpose of this review is to explore the risk factors associated with suicides in the elderly, provide an overview of the epidemiology of firearm-related suicides in older Americans, and explore methods of preventing firearm suicides in the elderly. The vast majority (70 %) of elderly suicides in the U.S were committed using a firearm. Elderly firearm suicides have increased by 49 % between 2010 and 2018, disproportionately affecting white males. Yearly firearm suicides in the elderly ranged from 4,276 in 2010 to 6,375 in 2018. In 2018, the rate of elderly male firearm suicides was 24.96/100,000 compared to a rate of 1.92/100,000 for elderly females, a rate ratio of 13 to 1 for males compared to females. The primary risk factors for elderly firearm suicides seem to be physical illnesses, mental illnesses, and social factors. Older Americans engage in suicidal behaviors with greater planning and lethality of intent than do young adults. Of all the strategies to prevent suicides with firearms, the most efficacious measures based on current research seem to be state firearm legislation and improving mental healthcare, but these effects are not specific to the elderly. Strengthening state firearm laws and improving mental healthcare for the elderly may have promise in preventing elderly firearm-related suicides. Additional implications for practice and research are discussed in this review.

An epidemiologic study of suicide among firefighters: Findings from the National Violent Death Reporting System, 2003 - 2017

Suicide is a significant concern among fire service due to high rates of suicide behaviors. The aim of this study was to describe suicides among firefighters using national suicide death data. Data from the National Violent Death Reporting System for 722 firefighters and 192,430 non-firefighters were analyzed to compare sociodemographics and risk factors between firefighter and non-firefighter decedents; and among firefighters based on suicide means. A greater proportion of firefighter decedents died by firearm compared to non-firefighters. Firefighter decedents were less likely to have been diagnosed with depression, but more likely to have been diagnosed with post-traumatic stress disorder compared to non-firefighters. A greater percentage of firefighter decedents had a relationship or physical health problem prior to death, but a lower percentage had a history of suicide thoughts/attempts. Among firefighter decedents, multivariate analysis showed physical health problems and disclosing suicide intent predicted death by firearm. Greater awareness of risk factors, reduced access to lethal means, and ensuring access to behavioral health services may aide in decreasing suicide mortality in this population. These findings should be interpreted with caution due to limitations concerning report accuracy, generalizability, small female sample size, and inclusion of data only for lethal suicide attempts.

Veterans, Firearms, and Suicide: Safe Storage Prevention Policy and the PREVENTS Roadmap

BACKGROUND

US veterans die by suicide at a higher rate than that of the civilian population and are more likely to use a firearm as their method. Systemic efforts to address the use of firearms in suicide had been largely evaded. In June 2020, the White House published the Roadmap to Empower Veterans and End the National Tragedy of Suicide (PREVENTS) task force report, which verified the link between, and the need to address, at-risk veterans and their access to firearms. This paper reviews the literature on the intersection of veterans, firearms, and suicide, then explores existing VA prevention initiatives aimed at reducing at-risk veterans' access to lethal means and offers policy recommendations to expand efforts in the context of the PREVENTS Roadmap.

OBSERVATIONS

The PREVENTS report recommends widespread distribution of safety education materials that encourage at-risk individuals to temporarily transfer or store their guns safely and the expansion of free or affordable options for storing weapons. Recommended policy actions to accomplish this goal include delaying access to firearms for at-risk veterans, facilitating temporary storage out of the home, improving in-home safe storage options, requiring that health care providers who care for high-risk veterans are trained in lethal means safety counseling, and creating campaigns to shift cultural norms for firearms' storage during crises.

CONCLUSIONS

Suicide prevention requires a multimodal approach, and attention to firearms access must become a more salient component. The high rate of veteran suicides involving firearms requires far-reaching interventions at societal, institutional, community, family, and individual levels.
