A systematic review of elderly suicide prevention programs

Late-life suicide: machine learning predictors from a large European longitudinal cohort

Background

People in late adulthood die by suicide at the highest rate worldwide. However, there are still no tools to help predict the risk of death from suicide in old age. Here, we leveraged the Survey of Health, Ageing, and Retirement in Europe (SHARE) prospective dataset to train and test a machine learning model to identify predictors for suicide in late life.

Methods

Of more than 16,000 deaths recorded, 74 were suicides. We matched 73 individuals who died by suicide with people who died by accident, according to sex (28.8% female in the total sample), age at death (67 ± 16.4 years), suicidal ideation (measured with the EURO-D scale), and the number of chronic illnesses. A random forest algorithm was trained on demographic data, physical health, depression, and cognitive functioning to extract essential variables for predicting death from suicide and then tested on the test set.

Results

The random forest algorithm had an accuracy of 79% (95% CI 0.60-0.92, p = 0.002), a sensitivity of.80, and a specificity of.78. Among the variables contributing to the model performance, the three most important factors were how long the participant was ill before death, the frequency of contact with the next of kin and the number of offspring still alive.

Conclusions

Prospective clinical and social information can predict death from suicide with good accuracy in late adulthood. Most of the variables that surfaced as risk factors can be attributed to the construct of social connectedness, which has been shown to play a decisive role in suicide in late life.

Disease burden and attributable risk factors of lip and oral cavity cancer in China from 1990 to 2021 and its prediction to 2031

Aims

This study addresses the essential need for updated information on the burden of lip and oral cavity cancer (LOC) in China for informed healthcare planning. We aim to estimate the temporal trends and the attributable burdens of selected risk factors of LOC in China (1990-2021), and to predict the possible trends (2022-2031).

Subject and methods

Analysis was conducted using data from the Global Burden of Disease study (GBD) 2021, encompassing six key metrics: incidence, mortality, prevalence, disability-adjusted life years (DALYs), years lived with disability (YLDs), and years of life lost (YLLs). Absolute number and age-standardized rates, alongside 95% uncertainty intervals, were computed. Forecasting of disease burden from 2022 to 2031 was performed using an autoregressive integrated moving average (ARIMA) model.

Results

Over the observed period (1990-2021), there were notable increases in the number of deaths (142.2%), incidence (283.7%), prevalence (438.0%), DALYs (109.2%), YLDs (341.2%), and YLLs (105.1%). Age-standardized rates demonstrated notable changes, showing decreases and increases of -5.8, 57.3, 143.7, -8.9%, 85.8%, and - 10.7% in the respective metrics. The substantial majority of LOC burden was observed among individuals aged 40-79 years, and LOC may exhibit a higher burden among males in China. From 2022 to 2031, the age-standardized rate of incidence, prevalence, and YLDs of LOC showed upward trends; while mortality, DALYs, and YLLs showed downward trends, and their estimated values were predicted to change to 2.72, 10.47, 1.11, 1.10, 28.52, and 27.43 per 100,000 in 2031, respectively. Notably, tobacco and high alcohol use emerged as predominant risk factors contributing to the burden of LOC.

Conclusion

Between 1990 and 2021, the disability burden from LOC in China increased, while the death burden decreased, and projections suggest these trends will persist over the next decade. A significant portion of this disease burden to modifiable risk factors, specifically tobacco use and excessive alcohol consumption, predominantly affecting males and individuals aged 40-79 years. Attention to these areas is essential for implementing targeted interventions and reducing the impact of LOC in China.

Neurobiology and medico-legal aspects of suicides among older adults: a narrative review

The task of preventing suicide in older adults is an important social burden as older adults aged above 65 are exposed to singular psychological aspects that increase suicide risks. Moreover, when an older adult corpse is found, the medico-legal inspection represents a fundamental tool to identify the exact cause of death, classifying or excluding it as suicide. In this scenario, this review aims to explore the neurobiological factors that could be related to suicidal behavior in older adults. A further goal of this review is the exploration of the medico-legal aspects surrounding older adult suicides, clarifying the importance of forensic investigation. Particularly, this review examines issues such as neurotransmitter imbalances, cognitive impairment, neuroinflammation, psychosocial factors related to geriatric suicide, and neurodegenerative diseases. Additionally, medico-legal aspects such as policy considerations, legal frameworks, mental health assessments, ethical implications and forensic investigation were explored. Considering the importance of this phenomenon, especially in western countries, a need has emerged for focused screening tools on suicidal behavior among older adults, in order to contain it. Therefore, this review makes an exhaustive appraisal of the literature giving insights into the delicate interplay between neurobiology as well as mental health in relation to older adult suicide within a medico-legal context. The comprehension of different aspects about this complex phenomenon is fundamental to propose new and more effective interventions, supporting tailored initiatives such as family support and improving healthcare, specifically towards vulnerable ageing societies to reduce older adult suicide risks.

Global, regional, and national time trends in incidence for depressive disorders, from 1990 to 2019: an age-period-cohort analysis for the GBD 2019

BACKGROUND

Even with advances in primary health care, depressive disorders remain a major global public health problem. We conducted an in-depth analysis of global, regional and national trends in depressive disorders incidence over the past 30 years.

METHODS

Data on the incidence of depressive disorders were obtained by sex (female, male, and both), location (204 countries), age (5-84 years), year (1990-2019) from the Global Burden of Disease Study (GBD) 2019. Further, age-period-cohort modeling was used to estimate the net drift, local drift, age, period and cohort effects between 1990 and 2019.

RESULTS

In 2019, although the incidence of depressive disorders has increased by 59.3% to 290 million (95% UI: 256, 328), the age-standardized incidence rate has decreased by 2.35% to 3588.25 per 100,000 people (3152.71, 4060.42) compared to 1990. There was an emerging transition of incidences from the young and middle-aged population to the old population. From 1990 to 2019, the net drift of incidence rate ranged from -0.54% (-0.61%, -0.47%) in low-middle Socio-demographic Index (SDI) regions to 0.52% (0.25%, 0.79%) in high SDI regions. Globally, the incidence rate of depressive disorders increases with age, period effects showing a decreasing risk and cohort effects beginning to decline after the 1960s.

CONCLUSIONS

Our current findings reflect substantial health disparities and potential priority-setting of depressive disorders incidence in the three dimensions of age, period and cohort across SDI regions, countries. The scope of healthcare to improve the progression of depressive disorders events can be expanded to include males, females of all ages.

World Psychiatric Association-Asian Journal of Psychiatry Commission on Public Mental Health

Although there is considerable evidence showing that the prevention of mental illnesses and adverse outcomes and mental health promotion can help people lead better and more functional lives, public mental health remains overlooked in the broader contexts of psychiatry and public health. Likewise, in undergraduate and postgraduate medical curricula, prevention and mental health promotion have often been ignored. However, there has been a recent increase in interest in public mental health, including an emphasis on the prevention of psychiatric disorders and improving individual and community wellbeing to support life trajectories, from childhood through to adulthood and into older age. These lifespan approaches have significant potential to reduce the onset of mental illnesses and the related burdens for the individual and communities, as well as mitigating social, economic, and political costs. Informed by principles of social justice and respect for human rights, this may be especially important for addressing salient problems in communities with distinct vulnerabilities, where prominent disadvantages and barriers for care delivery exist. Therefore, this Commission aims to address these topics, providing a narrative overview of relevant literature and suggesting ways forward. Additionally, proposals for improving mental health and preventing mental illnesses and adverse outcomes are presented, particularly amongst at-risk populations.

Advancing suicide prevention in Germany, Austria and Switzerland: a qualitative study

Introduction

Suicide is a significant public health problem, impacting individuals, families and communities worldwide. Effective suicide prevention requires a comprehensive approach with diverse integrated interventions and collaboration across sectors, stakeholders and professions. This study aims to identify challenges, gaps and success factors in current suicide prevention efforts in Germany, Austria and Switzerland, providing specific recommendations for advancement.

Methods

We conducted online, semi-structured interviews with 36 suicide prevention experts from Germany, Austria and Switzerland, incorporating perspectives from policy, science and practice. Interviews were conducted between September 2022 and February 2023, audio-recorded, transcribed verbatim and analyzed using the Framework method.

Results

Despite progress in national strategies and coordinated efforts for suicide prevention, challenges such as resource scarcity, stigma and structural issues in psychiatric and psychotherapeutic care persist. The interviewees identified several areas for advancement, including developing targeted prevention measures for men and older people, strengthening collaboration across sectors, stakeholders and professions, and increasing the involvement of individuals with lived experience. While the COVID-19 pandemic has exacerbated challenges in psychiatric and psychotherapeutic care, it has concurrently strengthened interest in suicide prevention among policymakers and the media.

Discussion

National suicide prevention strategies play a crucial role in setting priorities, raising public awareness, and guiding action. However, since most suicide prevention efforts are still predominantly health sector-driven, a more comprehensive approach is needed to promote the involvement of all relevant actors and address suicidality as a collective societal responsibility. Tailoring prevention programs for risk groups like older people and men is important, as these populations show high suicide rates and face a lack of targeted interventions. Our study underscores the importance to continuously monitor, refine and strengthen collaborative and evidence-based suicide prevention efforts.

A systematic review of psychosocial protective factors against suicide and suicidality among older adults

BACKGROUND

Research on suicide rarely focuses on protective factors. The goal of this systematic review was to assess the evidence of the associations between protective factors and reduced suicidality among older adults.

METHOD

First, a scoping review was conducted to identify pertinent terms that refer to various protective factors against suicidality. A systematic review, following the PRISMA guidelines, was then conducted on a selection of 15 protective factors (e.g., perceived control, well-being and quality of life, life satisfaction, purpose-in-life, resilience, coping, religiosity, hope, self-regulation, sense of belonging, mattering, positive relationship, social support, social connectedness, and social participation), with separate searches performed on each factor in five databases. Empirical studies were eligible if participants were adults aged 60 years and over, and if the studies reported predictive statistical analysis.

RESULTS

A total of 70 studies were retained for the review. Suicidal ideation was the main outcome measure (91%). Significant associations were consistently observed between all protective factors and reduced suicidal ideations or behaviors, particularly for purpose-in-life, resilience, and positive relationships, indicating that these are solid components for suicide prevention. Using scales, instead of a single item, to measure protective factors (e.g. life satisfaction) was more efficient to capture the associations. On the other hand, results were similar whether studies used subjective (e.g., sense of belonging) or objective (e.g., social connectedness) measures.

CONCLUSION

Protective factors were inversely associated with suicidal ideation. Improving protective factors is essential for the development of late-life suicide prevention and interventions, instead of merely focusing on risk factors.

[Suicide prevention in old age : Importance of depressive disorders and implications for the discussion on assisted suicide]

This article gives an overview of possibilities for suicide prevention in old age, with an emphasis on depression. A broad range of approaches are available, which are described differentiated into universal, selective and indicated strategies. In Germany the working group "Old people" of the National Suicide Prevention Program (NaSPro) has worked out these strategies in a differentiated way and with respect to the international discussions. The influence of the debate on assisted suicide and the influence of cognitive changes on suicidal ideation in old age are discussed. A further large need for concrete measures and also the presence of large gaps in the care structures are determined.

Exploring community mental health service use following hospital-treated intentional self-harm among older Australians: a survival analysis

OBJECTIVES

This study aimed to examine the impact of community mental health (CMH) care following index hospital-treated intentional self-harm (ISH) on all-cause mortality. A secondary aim was to describe patterns of CMH care surrounding index hospital-treated ISH.

DESIGN

A longitudinal whole-of-population record linkage study was conducted (2014-2019), with index ISH hospitalization (Emergency Department and/or hospital admissions) linked to all available hospital, deaths/cause of death, and CMH data.

SETTING

Australia's most populous state, New South Wales (NSW) comprised approximately 7.7 million people during the study period. CMH services are provided statewide, to assess and treat non-admitted patients, including post-discharge review.

PARTICIPANTS

Individuals with an index hospital presentation in NSW of ISH during the study period, aged 45 years or older.

INTERVENTION

CMH care within 14 days from index, versus not.

MEASUREMENTS

Cox-proportionate hazards regression analysis evaluated all-cause mortality risk, adjusted for relevant covariates.

RESULTS

Totally, 24,544 persons aged 45 years or older experienced a nonfatal hospital-treated ISH diagnosis between 2014 and 2019. CMH care was received by 56% within 14 days from index. Survival analysis demonstrated this was associated with 34% lower risk of death, adjusted for age, sex, marital status, index diagnosis, and 14-day hospital readmission (HR 0.66, 95% CI 0.58, 0.74, p < 0.001). Older males and chronic injury conveyed significantly greater risk of death overall.

CONCLUSIONS

CMH care within 14 days of index presentation for self-harm may reduce the risk of all-cause mortality. Greater effort is needed to engage older males presenting for self-harm in ongoing community mental health care.

Urban green and blue spaces and general and mental health among older adults in Washington state: Analysis of BRFSS data between 2011-2019

A growing body of evidence highlights the significant effect of built environment features on mental and general health. This study examined the association between distance to and percentage of green and blue space measures and serious psychological distress, general health, and frequent mental distress among older adults living in urban ZIP codes in Washington state. Percentage of green space, particularly tree canopy and forest space, was significantly associated with better self-rated general health and reduced odds of serious psychological distress. Closer distance to blue space was associated with better self-rated general health. Programs which incentivize exposure to green and blue spaces for urban-dwelling, older adults may improve health outcomes.

Death by suicide among aged care recipients in Australia 2008-2017

OBJECTIVE

To characterize the features of aged care users who died by suicide and examine the use of mental health services and psychopharmacotherapy in the year before death.

DESIGN

Population-based, retrospective exploratory study.

SETTING AND PARTICIPANTS

Individuals who died while accessing or waiting for permanent residential aged care (PRAC) or home care packages in Australia between 2008 and 2017.

MEASUREMENTS

Linked datasets describing aged care use, date and cause of death, health care use, medication use, and state-based hospital data collections.

RESULTS

Of 532,507 people who died, 354 (0.07%) died by suicide, including 81 receiving a home care package (0.17% of all home care package deaths), 129 in PRAC (0.03% of all deaths in PRAC), and 144 approved for but awaiting care (0.23% of all deaths while awaiting care). Factors associated with death by suicide compared to death by another cause were male sex, having a mental health condition, not having dementia, less frailty, and a hospitalization for self-injury in the year before death. Among those who were awaiting care, being born outside Australia, living alone, and not having a carer were associated with death by suicide. Those who died by suicide more often accessed Government-subsidized mental health services in the year before their death than those who died by another cause.

CONCLUSIONS

Older men, those with diagnosed mental health conditions, those living alone and without an informal carer, and those hospitalized for self-injury are key targets for suicide prevention efforts.

Modeling suicidal ideation in Korean older adults based on their social relationships and mental health: a meta-analytic path analysis

OBJECTIVES

Elder suicide is a serious concern in many countries, including South Korea. Various policies and programs to prevent elder suicide are essential; however, further understanding of this phenomenon is necessary. The current study, therefore, developed a model for understanding the underlying mechanism of suicidal ideation in older adults in South Korea. The model was based on Andersen's theory (2021), which explains the path from social relationships to mental health.

METHODS

This study was conducted utilizing meta-analytic structural equation modeling in accordance with a pooled correlation matrix. We used data from 93 existing studies systematically identified in nine academic databases.

RESULTS

The fit statistics show that our model fits the data well. The results demonstrated that suicidal ideation was directly affected by abuse, depression, and self-esteem but not by family relationships. Depression significantly mediated the relationship between abuse and suicidal ideation and between family relationships and suicidal ideation.

CONCLUSION

Social relationships play an important role in determining mental health among Korean older adults, consistent with Andersen's theory. Prevention of elder abuse and depression is essential in preventing suicide among older adults in South Korea.

Resilience as a Protective Factor in Older Adult Suicide: A Rapid Review

Nearly 700,000 suicide deaths occur each year. One in every five suicide death occurs among adults over 60 years of age or older. As the aging population increases rapidly, there is a need to understand protective factors to prevent older adult suicide. This study used the rapid review methodology to search literature from 1997 to 2022, examining whether resilience was a protective factor. The literature search was conducted over the following six databases for peer-reviewed journals and gray literature including Abstracts in Social Gerontology, Academic Search Premier, APA PsycInfo, CINAHL Complete, MEDLINE, and SocINDEX with Full Text. A total of six peer-reviewed journal articles met the inclusion criteria. The conclusion of the articles suggested resilience may be a protective factor in older adult suicide. Despite its underpinning, resilience in suicide prevention literature is lacking. More studies should examine resilience and its constructs as part of the effort to prevent older adult suicide.

Dying by Suicide in Nursing Homes: A Preventable End of Life Outcome for Older Residents

Suicide research and suicide prevention have given comparatively little attention to the older adult residents of nursing homes. This population is characterized by advanced age, significant infirmity, limited autonomy and social connections, and other factors associated with high suicide risk such as self-neglect. However, little is known of the actual incidence and prevalence of suicide in older adults in such residential care settings, partly because of how such deaths are reported. Suicide risk screenings are nominal, facility staff lack training to identify signs of suicidality, and suicide prevention programs are not common in the nursing home industry. These deficits can be remedied by increasing awareness among family members, facility caregivers, contracted providers, community aging services, accrediting and regulatory agencies, and residents.

The relationship between intergenerational financial support and depressive symptoms among older adults: Evidence from China Health and Retirement Longitudinal Study, 2011-2018

OBJECTIVE

Aimed to investigate the effect of intergenerational financial support on depressive symptoms among older adults over time.

METHODS

Data were obtained from China Health and Retirement Longitudinal Study (CHARLS) 2011, 2013, 2015, and 2018. A finite distributed lag (FDL) model was employed, long-run cumulative effect was evaluated. 1426 respondents followed in four waves were included in FDL model. CES-D score was used to measure depressive symptoms, intergenerational financial support was defined as financial support received from older adults' children or grandchildren. Sociodemographic characteristics, health behaviors, social insurance, and social contact factors were controlled in the model.

RESULTS

More than a third older adults in China had a CES-D score of 10 or higher. Intergenerational financial support has a significant long-run cumulative negative effect on older adults' depressive symptoms (CES-D scores: coef. = -0.674, P < 0.001; % with CES-D scores ≥10: Coef. = -0.154, P = 0.018). While, the intergenerational financial support in previous period exhibited a significant negative association with depressive symptoms, the 2, 3, and 4 periods did not reach statistical significance.

CONCLUSIONS

Intergenerational financial support has a significant negative effect on older adults' depressive symptoms over time, while the effect may diminish. Programs need to be explored to support home-based eldercare to mitigate this diminished effect.

Understanding the Factors Contributing to Suicide Among the Geriatric Population: A Narrative Review

A critical health concern for older adults is suicide, particularly for those above the age of 60 years. Despite this, research on suicide in this age group is relatively scarce compared to studies on younger populations. This article is intended to summarize the existing literature on etiological/risk factors, including problems with one's physical and mental health, social isolation, money, and life changes like retirement and the death of a spouse and methods for preventing suicide specific to the geriatric population. We conducted a comprehensive literature search to identify the original reports and reviewed publications through various databases, including Google Scholar, PubMed, and the CDC. We gathered information on Google from reputable sources such as the WHO and the National Crime Records Bureau (NCRB). Our review found that the risk factor of suicide in the geriatric population includes physical illness, familial issues, financial issues, and hopelessness. The suicide rate for older adults declined, dropping from 16.17 per 100,000 individuals to 14.25 per 100,000 individuals aged 50 to 69 years and from 27.45 per 100,000 individuals to 24.53 per 100,000 individuals for those over 70 years. A more significant proportion of elderly suicide attempters come from rural than urban locations. Young individuals have better professional opportunities in urban areas, but older people are dispersed to underdeveloped or rural areas, where they are more likely to experience social isolation. By systematically identifying these risk factors, we can develop prevention and intervention strategies to decrease the suicide rates among the geriatric population.

An elderly patient with depression and a suicide attempt during the COVID-19 pandemic: a case report

Objective

Elderly individuals are among the age groups with the highest risk of suicide. The coronavirus (COVID-19) pandemic forced isolation and resulted in an increased risk of depression, hopelessness, and perceived burdensomeness among the elderly, thereby increasing the risk of suicide.

Methods

This is a case report of an elderly single retired school principal with obsessive-compulsive personality traits who developed depression with psychotic symptoms after being isolated following the movement control order (MCO) during the COVID-19 pandemic. The social isolation led to feelings of loneliness and hopelessness. The patient's depressive symptoms worsened after he developed physical illnesses, such as eye floaters, that affected his daily activities. This caused him to have suicidal ideation to the extent that he attempted suicide by ingesting 90 mL of pesticide. Two weeks prior to the attempt, he updated his will and asked his friend to keep it. After the suicide attempt, he vomited and had diarrhea and epigastric pain. He called his friend, who brought him to the hospital emergency room (ER). He was resuscitated and subsequently admitted to the intensive care unit (ICU). After being medically stabilized, he was transferred to the psychiatric ward, where further treatment was administered for his depression. His depressive symptoms and suicidal ideation improved after he was administered antidepressants and psychotherapy.

Results

The impact of the COVID pandemic has led to a surge in mental health issues such as anxiety and depression. The elderly are among the highest-risk groups of individuals to contract or die of COVID-19 infection, and they are also the most likely to develop mental health issues related to the pandemic. Furthermore, the risk of death by suicide is highest in this age group due to physical illness, social isolation, and the lack of a support system. This case also highlights the need for awareness of suicidal ideation screening among non-medical healthcare professionals and religious organizations to avoid the treatment gap.

Conclusion

It is essential to enhance suicide risk assessment and management among the elderly after the COVID-19 pandemic.

Use of Psychoactive Medications and Risk of Suicide in Late Life (75+): A Total Population Study

BACKGROUND

Psychoactive medications play an important role for the mental health and risk of suicidal behaviour in the oldest segment of the population (75+). A better understanding of psychoactive medication use is advocated to prevent suicide in this age group.

PURPOSE

We investigated the risk of suicide associated with the use of psychoactive medications in the total population aged ≥ 75 years, with and without exposure to antidepressants.

METHOD

A national population-based register study, including all Swedish residents aged ≥ 75 years between 2006 and 2014 (N = 1,413,806). A nested case-control design was used to investigate psychoactive medications associated with suicide among users and non-users of antidepressants. Risk estimates were calculated in adjusted conditional logistic regression models for the entire cohort and by gender.

RESULTS

Suicide occurred in 1305 persons (907 men and 398 women). Among them, 555 (42.5%) were on an antidepressant at the time of suicide. Adjusted incidence rate ratio (aIRR) for suicide was increased in those who were on hypnotics in the total cohort (aIRR 2.05, 95% confidence interval 1.74 to 2.41), in both users and non-users of antidepressants and for both genders. Elevated suicide risk was observed in those who concomitantly used anxiolytics with antidepressants (1.51, 1.25 to 1.83). Decreased risk of suicide was observed among those who were on anti-dementia drugs, in the total cohort (0.33, 0.21 to 0.52) and in both users and non-users of antidepressants. Use of antipsychotics and mood stabilisers showed no effect on suicide risk.

CONCLUSION

Use of hypnotics and concomitant use of anxiolytics with antidepressants was associated with increased risk of late-life suicide. Our findings suggest the need for careful evaluation of the benefit-risk balance of psychoactive medications as well as their availability as a possible suicide means. Future research should consider the indication of use of the psychoactive medications and the severity of psychiatric and medical illnesses of the patients.

Psychiatric disorders among adult deliberate self-harm patients and subsequent risk of dying by suicide, mental and behavioural disorders and other external causes

INTRODUCTION

Deliberate self-harm (DSH) treated in general hospital is a well-established risk factor for suicide and other cause mortality. However, few studies have used population data to investigate the differential impact of specific psychiatric disorders on the risk of subsequent suicide, by sex and age of the patient in the context of previous DSH episodes.

METHOD

All patients aged 18 and older treated for DSH in general hospitals during the period 2008-2018 were identified through national registers. Cox proportional hazards regression was used to ascertain the associated risk of death by suicide, mental and behavioural disorder and other external causes.

RESULTS

The cohort consisted of 39 479 patients of which 878 died by suicide, 461 by mental and behavioural disorders and 1037 by other external causes. Overall, schizophrenia spectrum disorders, affective disorders and personality disorders increased the risk of suicide. Large gender and age differences were identified in the risk of suicide associated with personality disorders and affective disorders. Alcohol use disorders and dementia increased the risk of dying by mental and behavioural disorders and alcohol use disorders and other substance use disorders increased the risk of death by external causes.

CONCLUSION

Schizophrenia spectrum disorders, affective disorders and personality disorders increased the risk of suicide among DSH patients, but the effect varied by gender, age and history of previous DSH. Psychiatric evaluation of all DSH patients and treatment tailored to the patient's specific needs is essential to reduce the risk of premature death.

Interventions of choice for the prevention and treatment of suicidal behaviours: An umbrella review

AIM

This umbrella review aims to determine which interventions can be considered as effective in the prevention and treatment of suicidal behaviour.

DESIGN

Umbrella review.

METHODS

A systematic search was conducted of works indexed in the PubMed, CINAHL, Cochrane Database of Systematic Reviews, Scopus, ISI Web of Knowledge and Joanna Institute Briggs databases. The search covered works published from 2011 to 2020.

RESULTS

The scientific literature shows that, in addition to being the most prevalent interventions in use, dialectical and cognitive behavioural therapies are the most effective in the treatment and management of suicide attempts and suicidal ideation. It is shown that the prevention and treatment of suicidal behaviour requires multidisciplinary and comprehensive management. Among the interventions that stand out the most are the promotion of providing coping tools, work based on thought and behaviour, and behavioural, psychoanalytic and psychodynamic therapies for the management of emotions.

Factors Affecting Emergency Medical Utilization After Self-harm and Effectiveness of Community-Based Suicide Prevention Provisions in Preventing Self-harm: A Nationwide Registry-Based Study in Korea

In order to formulate and implement a community-based suicide prevention program, as well as evaluate the effectiveness of these programs, it is necessary to understand the epidemiological characteristics of self-harm. Clinical data were collected from the National Emergency Department Information System (NEDIS) data panel in Korea for patients seen after self-harm episodes. Socioeconomic factors were collected from Statistics Korea. Variables representing SP provisions (SPPs) were collected from the Korea Foundation for Suicide Prevention. Increasing the number of mental health providers resulted in lower annual emergency department visit rate after self-harm (VRSH) in the entire population, as well as in both the young and elderly populations. An increase in the mental health budget led to a significant reduction in VRSHs. However, the number of suicide prevention centers did not have any significant association with the VRSH. This study also provides substantial evidence that community-based SPPs are effective in preventing self-harm.

Affiliation to a Social Group as a Preventive Factor in Suicidal Behaviors in Children and Adolescents during the COVID-19 Pandemic

Suicide is one of the most common causes of death in the population of children and adolescents. Available data show the continuous growth of this phenomenon and the ineffectiveness of prevention programs. Additionally, the COVID-19 pandemic significantly affected young people's mental health, including an increased risk of suicidal behaviors due to limited direct contact with the school and peer groups in favor of the home environment. Therefore, the aim of this narrative review was to consider the risk factors and protective factors for suicidal behavior in the under-18 population, with a particular focus on the importance of belonging to a social group and building identification with it as a phenomenon protecting against suicidal behavior. Additionally, in this review, we evaluate how the COVID-19 pandemic affected these relationships. The PubMed database was used in the search with the following keywords: suicide, suicide behaviors, child and adolescent suicide behaviors, group affiliation, family affiliation, ethnicity, religious affiliation, and the COVID-19 pandemic, with articles published between 2002 and 2022 analyzed. Research conducted to date indicates that both sustained and stable family and peer relationships, as well as a sense of identification and belonging, noticeably reduce the risk of suicidal behavior. Ethnic or cultural affiliation seems to have been particularly important during the isolation in the home environment caused by the COVID-19 pandemic. Additionally, it has been shown that while in lockdown, contact through social media with individuals' identification groups was associated with a reduced chance of emotional crises. Furthermore, regardless of cultural background, attachment to a particular group correlates with enhanced psychiatric state of children and adolescents. Thus, available data highlight the need for building and maintaining affiliations with suitable groups as a protective factor against suicidal behaviors.

Assessment of a Suicide Prevention Gatekeeper Training Program for Nursing Home Staff

INTRODUCTION

Older adults have one of the highest age-specific suicide rates in France, and the risk of suicide is higher for those living in nursing homes. The aim of our study was to assess the effectiveness of gatekeeper training for nursing home staff on the knowledge and stigmas towards suicidal crisis and the impact on suicidal behaviour rates.

METHOD

A total of 427 nursing or administrative staff from 110 nursing homes received gatekeeper training in the Hauts-de-France French region between September 2016 and June 2018. First, knowledge and stigmas on suicidal crisis were assessed through a pretest and posttest survey. Second, a retrospective survey was conducted to determine suicide behaviour rates before and after training in nursing homes. Then, changes between pre- and posttraining scores and suicide rates were evaluated with a paired samples T test and rate difference calculation (P value of <0.05 was considered statistically significant).

RESULTS

A total of 315 trainees completed the questionnaires on knowledge and stigmas related to suicidal crisis, and we found a significant difference in the total scores (P < 0.01). Moreover, we found a significant decrease in the incidence of suicide attempts (SAs) after training (P = 0.002), but the incidence of deaths by suicide was not significantly different prior to and after the training course (P = 0.46).

CONCLUSION

We highlighted an improvement in knowledge and stigmas after training and a reduction in the rates of SAs with our gatekeeper suicide prevention program. Future research is needed to improve suicide prevention for nursing home residents.

Apolipoprotein E genotype, inflammatory biomarkers, and non-psychiatric multimorbidity contribute to the suicidal ideation phenotype in older age. The Salus in Apulia Study

BACKGROUND

Possible relationships between suicidal ideation and biopsychosocial predictors in older age are unclear. In the population-based Salus in Apulia Study, we investigated the relationships among biomarkers, socio-demographic, psychopathological, inflammatory and metabolic characteristics and suicidal ideation in 1252 older subjects.

METHODS

Suicidal ideation was evaluated with the brief version of the Columbia-Suicide Severity Rating Scale. Apolipoprotein E (APOE) genotype and inflammatory profile [interleukin (IL)-6, tumor necrosis factor (TNF)-α, C-reactive protein (CRP)] were evaluated. A machine learning algorithm, the Random Forest (RF), selected potential biopsychosocial factors associated to suicidal ideation.

RESULTS

Suicidal ideators accounted for 2.32 % of subjects, were female, smokers, and obese with multimorbidity. After adjusting for age, gender, education and social dysfunction, logistic regression analyses revealed that suicidal ideation was associated to late-life depression (LLD) (odds ratio:21.71,95 % confidence interval:9.22-51.14). In the full RF model, asthma was the most important contributor to suicidal ideation. In the final RF model, education, age, and mild cognitive impairment followed by gender and global cognition were considered the most important contributors. Among biomarkers, in the final RF model, IL-6 followed by TNF-α, APOE ε4 allele presence, CRP and high-density lipoprotein cholesterol contributed most to suicidal ideation.

LIMITATIONS

A relatively small number of older subjects with suicidal ideation (2.3 %); we did not distinguish between active and passive suicidal ideation.

CONCLUSIONS

Although LLD is a strong determinant of suicidal ideation, other non-psychiatric factors, i.e., serum inflammation biomarkers, APOE ε4 allele, and multimorbidity, should be taken into account when evaluating a suicidal ideation phenotype in older age.

A Qualitative Analysis of Suicide Notes to Understand Suicidality in Older Adults

OBJECTIVE

Suicide is a complex multifactorial process influenced by a variety of biological, psychological, and social stressors. Many older adults face a characteristic set of challenges that predispose them to suicidal ideation, suicide-related behavior, and death by suicide. This study explored the subjective experience of suicidality through the analysis of suicide notes from older adults.

DESIGN

Qualitative study analyzing written suicide notes.

SETTING

Written notes for suicide deaths in Toronto, Canada, between 2003 and 2009 were obtained from the Office of the Chief Coroner for Ontario.

PARTICIPANTS

The analysis comprised 29 suicide notes (mean words per note: 221; range: 6-1095) written by individuals 65 years and older (mean ± SD age: 76.2 ± 8.3).

MEASUREMENTS

We employed a constructivist grounded theory framework for the analysis, conducted through line-by-line open coding, axial coding, and theorizing of data to establish themes.

RESULTS

Suicide notes elucidated the writers' conception of suicide and their emotional responses to stressors. Expressed narratives contributing to suicide centered on burdensomeness or guilt, experiences of mental illness, loneliness or isolation, and poor physical health or disability. Terms related to pain, poor sleep, apology, and inability to go on were recurrent.

CONCLUSIONS

Suicide notes enrich our understanding of the thoughts and emotions of those at highest risk of suicide, and they inform potential interventions for reducing suicide risk in older adults.

A systematic review of evidence-based aftercare for older adults following self-harm

OBJECTIVE

Self-harm is closely associated with suicide in older adults and may provide opportunity to intervene to prevent suicide. This study aimed to systematically review recent evidence for three components of aftercare for older adults: (1) referral pathways, (2) assessment tools and safety planning approaches and (3) engagement and intervention strategies.

METHODS

Databases PubMed, Medline, PsychINFO, Embase and CINAHL were searched from January 2010 to 10 July 2021 by two reviewers. Empirical studies reporting aftercare interventions for older adults (aged 60+) following self-harm (including with suicidal intent) were included. Full text of articles with abstracts meeting inclusion criteria were obtained and independently reviewed by three authors to determine final studies for review. Two reviewers extracted data and assessed level of evidence (Oxford) and quality ratings (Alberta Heritage Foundation for Medical Research Standard Quality Assessment Criteria for quantitative and Attree and Milton checklist for qualitative studies), working independently.

RESULTS

Twenty studies were reviewed (15 quantitative; 5 qualitative). Levels of evidence were low (3, 4), and quality ratings of quantitative studies variable, although qualitative studies rated highly. Most studies of referral pathways were observational and demonstrated marked variation with no clear guidelines or imperatives for community psychiatric follow-up. Of four screening tools evaluated, three were suicide-specific and one screened for depression. An evidence-informed approach to safety planning was described using cases. Strategies for aftercare engagement and intervention included two multifaceted approaches, psychotherapy and qualitative insights from older people who self-harmed, carers and clinicians. The qualitative studies identified targets for improved aftercare engagement, focused on individual context, experiences and needs.

CONCLUSION

Dedicated older-adult aftercare interventions with a multifaceted, assertive follow-up approach accompanied by systemic change show promise but require further evaluation. Research is needed to explore the utility of needs assessment compared to screening and evaluate efficacy of safety planning and psychotherapeutic approaches.

Lifetime suicidal-related behaviour among patients in treatment for substance use disorder: A cross-sectional study

Suicidal-related behaviours are an important concern in individuals who present with substance use disorders (SUDs). The distinction among the specific characteristics of the different patients might help to improve prevention strategies. We describe and compare the sociodemographic characteristics, severity of addiction, and psychopathology of the participants depending on the severity of their lifetime suicidal behaviour. In addition, we examine whether the number of suicide attempts can be estimated based on the variables that differentiate the groups. A sample of 318 men and 86 women who sought treatment for addiction were assessed. The sample was divided into: no ideation or attempts, suicidal ideation, one suicide attempt, and two or more suicide attempts. The group with two or more suicide attempts exhibited a greater severity in the addiction profile. The group with one suicide attempt presented a higher psychopathological symptomatology at the time of the assessment. The severity of the Psychiatric area was related to the group with two or more attempts and to the number of suicide attempts. The presence of any number of attempts is associated with greater severity of addiction. Providing specific intervention strategies for SUD patients depending on their suicidal behaviours is promising for clinical application.

Suicidality in the geriatric population

Suicide in older adults is a major global concern in both public and mental health. With an ageing population on the rise, a surge in suicidal deaths is predicted in the coming years. The objectives of this paper are to review the risk factors, protective factors, assessment rating scales and current prevention strategies in the geriatric population. The identification of modifiable risk factors and strengthening of protective factors as well as staging according to suicidal ideation, behaviors and/or attempt(s) are necessary to devise appropriate personalized interventions in vulnerable older adults. A history or current psychiatric illness particularly depression, physical illnesses, previous suicide attempt, substance abuse, loneliness, marital status, financial stress, a family history of psychiatric illnesses or suicide in 1st degree relatives and low social support most commonly increase suicidal susceptibility in older adults. Conversely, factors that increase resilience in older adults include a good physical health and cognitive function, religiousness, good quality of life and life satisfaction, ability to perform activities of daily living, marital status, having friends and social connectedness. While the risk factors associated with suicide in the geriatric population are complex and multidimensional in nature, the current preventive strategies have provided no substantial decline in suicidal risk. Therefore, a combination of strategies applied via a multilevel prevention program at a primary, mental healthcare, societal and community level could mitigate suicidal risk. Further research and better preventive measures are warranted to diminish suicidal risk in older adults.

Predictive factors of nonfatal self-harm among community-dwelling older adults assessed for support services

BACKGROUND

Older adults receiving support services are a population at risk for self-harm due to physical illness and functional impairment, which are known risk factors. This study aims to investigate the relative importance of predictive factors of nonfatal self-harm among older adults assessed for support services in New Zealand.

METHODS

interRAI-Home Care (HC) national data of older adults (aged ≥ 60) were linked to mortality and hospital discharge data between January 1, 2012 and December 31, 2016. We calculated the crude incidence of self-harm per 100,000 person-years, and gender and age-adjusted standardized incidence ratios (SIRs). The Fine and Gray competing risk regression model was fitted to estimate the hazard ratio (HR; 95% CIs) of self-harm associated with various demographic, psychosocial, clinical factors, and summary scales.

RESULTS

A total of 93,501 older adults were included. At the end of the follow-up period, 251 (0.27%) people had at least one episode of nonfatal self-harm and 36,333 (38.86%) people died. The overall incidence of nonfatal self-harm was 160.39 (95% CI, 141.36-181.06) per 100,000 person-years and SIR was 5.12 (95% CI, 4.51-5.78), with the highest incidence in the first year of follow-up. Depression diagnosis (HR, 3.02, 2.26-4.03), at-risk alcohol use (2.38, 1.30-4.35), and bipolar disorder (2.18, 1.25-3.80) were the most significant risk factors. Protective effects were found with cancer (0.57, 0.36-0.89) and severe level of functional impairment measured by Activities of Daily Living (ADL) Hierarchy Scale (0.56, 0.35-0.89).

CONCLUSION

Psychiatric factors are the most significant predictors for nonfatal self-harm among older adults receiving support services. Our results can be used to inform healthcare professionals for timely identification of people at high risk of self-harm and the development of more efficient and targeted prevention strategies, with specific attention to individuals with depression or depressive symptoms, particularly in the first year of follow-up.

Diversify Your Emotional Assets: The Association Between the Variety of Sources of Emotional Support and Thoughts of Death or Self-harm Among US Older Adults

Using data from a nationally representative sample of community-dwelling older adults (age ≥ 65) (NHANES: n = 3,114), we examined the association between the variety in sources of emotional support and thoughts of death or self-harm in the past two weeks among US older adults and if such association is modified by gender and race/ethnicity. Overall, an additional category of source of emotional support was associated with the 0.36-fold lower odds of endorsing thoughts of death or self-harm in the past two weeks (WAOR: 0.64, 95% CI: 0.46-0.89), after controlling for demographic, socioeconomic, and health-related characteristics. The magnitudes of such association varied across different gender and racial/ethnic subgroups. While among older women and non-Hispanic Black older men, increase in the variety of sources of emotional support was associated with decrease in the odds of endorsing thoughts of death or self-harm in the past two weeks, for non-Hispanic White older men and Hispanic older men, increase in the variety of sources of emotional support was associated with increase in the odds of endorsing thoughts of death or self-harm in the past two weeks. Our findings highlight the importance of considering gender and race/ethnicity when designing and implementing successful interventions for reducing suicide ideation among diverse elderly persons.

Suicide among Older People in Different European Welfare Regimes: Does Economic (in)Security Have Implications for Suicide Prevention?

Older adult suicide rates vary widely within Europe, and differential welfare policies might contribute to this. We studied variations in economic indicators and suicide rates of people 65+ across 28 European countries and examined the effects of these indicators on suicide rates, grouping countries according to their socio-political systems and welfare regimes. Suicide data was obtained from the WHO European Mortality Database. The European Union Statistics on Income and Living Conditions and the European Union Labour Force Survey provided data on economic indicators. Linear mixed models were applied. Suicide rates ranged from 4.22/100,000 (Cyprus) to 36.37/100,000 (Hungary). Material deprivation was related to elevated suicide rates in both genders in the pooled data set and in men but not women in the Continental and Island countries. Higher ratio of median income (65+/under 65) was associated with lower likelihood of suicide in women in the South-Eastern European countries. In the Nordic region, the 65+ employment rate was associated with a decreased likelihood of suicide in men. These factors to some extent show economic insecurity against older people, which influences the likelihood of suicide. Active labor market policies and inclusive social environment may contribute to suicide prevention in this age group.

Suicide Prevention Interventions and Their Linkages in Multilayered Approaches for Older Adults: A Review and Comparison

Multilayered approaches to suicide prevention combine universal, selective, and indicated prevention interventions. These approaches may be more successful in reducing suicide rates among older adults if they link these layers more systematically: that is, if the programs are designed so that interventions at a lower level facilitate involvement at a higher level when appropriate. This study aimed to examine the effect on suicide rates of the structure of multilayered approaches, and in particular the types of interventions and the connections or linkages between them. We also wished to consider any different effects by sex. A literature search used PubMed and PsycINFO to identify systematic reviews of interventions in this age group. From the reference lists of these articles, we identified controlled studies assessing the impact of a multilayered program on suicide incidence among older adults. We were particularly interested in initiatives linking different kinds of prevention interventions. We found three relevant systematic reviews, and from these, we identified nine eligible studies. These included seven non-randomized controlled studies from rural areas in Japan (average eligible population: 3,087, 59% women, average duration: 8 years). We also found two cohort studies. The first was from a semi-urban area in Padua, Italy (18,600 service users, 84% women, duration: 11 years). The second was from urban Hong Kong, with 351 participants (57% women) over a 2-year follow-up period. We used a narrative synthesis of these studies to identify five different multilayered programs with different forms of connections or linkages between layers. Two studies/programs (Italy and Hong Kong) involved selective and indicated prevention interventions. One study/program (Yuri, Japan) included universal and selective prevention interventions, and the final six studies (two programs in northern Japan) involved linkages between all three layers. We also found that these linkages could be either formal or informal. Formal linkages were professional referrals between levels. Informal linkages included advice from professionals and self-referrals. Several of the studies noted that during the program, the service users developed relationships with services or providers, which may have facilitated movements between levels. All five programs were associated with reduced suicide incidence among women in the target groups or communities. Two programs were also associated with a reduction among men. The study authors speculated that women were more likely to accept services than men, and that the care provided in some studies did less to address issues that are more likely to affect men, such as suicidal impulsivity. We therefore suggest that it is important to build relationships between levels, especially between selective and indicated prevention interventions, but that these can be both formal and informal. Additionally, to reach older men, it may be important to create systematic methods to involve mental health professionals in the indicated prevention intervention. Universal interventions, especially in conjunction with systematically linked indicated and selective interventions, can help to disseminate the benefits across the community.

Over-the-counter drug use in suicidal/self-harm behavior: Scoping review

Background and aims

Minor physical ailments are treated with over-the-counter (OTC) medications. The availability of OTC drugs helps reduce waiting times and ease the suffering of many. Suicidal behavior includes suicidal ideation, attempts, and completed suicides and affects people of all ages, religions, and cultures. This study aims to review use of OTC drugs for self-harm and suicidal attempts.

Methods

We reviewed English language publications from the beginning of time to October 2021 on OTC drug use for suicidal behavior.

Results

Twenty-seven studies met the eligibility criteria, and 1,816,228 participants were reported in these publications. OTC analgesics and sedatives/hypnotics were frequently used for suicidal behavior. Females and young people mainly were reported to self-harm using OTC medications. An increase in OTC analgesic use for self-harm in adolescents during the school months was reported. Elderly persons use hypnotics more frequently for suicidal attempts. Persons with major psychiatric disorders were reported to use OTC for suicidal behavior.

Conclusion

The available information shows that the prevention strategies should focus on OTC analgesics and hypnotic use among women, the young, the elderly, and persons with mental health disorders.

Developing a Community-based Suicide Prevention Program in Primary Health Care

Currently, suicide has become one of the most critical public health challenges in low-and middle-income countries facing community mental health more broadly. However, most healthcare systems haven't efficient Suicide Prevention Programs (SPP), and only 18% of countries have a suicide registry system. In Malekan County of Iran, suicidal behaviors were recognized as a serious public health issue via a health community assessment. This study was aimed to describe the developing steps of a community-based SPP in Malekan County including review of systematic reviews, expert testimony, report to the health system, improving suicide registry coverage, conducting research, follow upping of suicide attempters, training gatekeepers, and public education campaign in the hot spots. These suggested the need to reinforce evaluate the effectiveness of the national health perspective in addressing the issues of suicide and suicidal behavior.

An Emotion Regulation Tablet App for Middle-Aged and Older Adults at High Suicide Risk: Feasibility, Acceptability, and Two Case Studies

OBJECTIVE

The unique features of technological applications may improve the treatment of people at risk of suicide. In this article, we present feasibility and acceptability data as well as two case studies demonstrating the use of WellPATH, a tablet app that aims to help suicidal patients during emotionally-charged situations outside of therapy sessions. The WellPATH app was part of a 12-week psychotherapy intervention (CRISP - Cognitive Reappraisal Intervention for Suicide Prevention) for middle-aged and older adults after their discharge from a suicide-related hospitalization.

DESIGN

The use of WellPATH includes three stages: preparation and practice, incorporation, and actual use.

MEASUREMENTS

Feasibility was measured by the overall use of WellPATH during 12 weeks, and acceptability was measured with the three items of the Client Satisfaction Questionnaire.

RESULTS

Twelve study participants were administered WellPATH as part of CRISP. The results provide preliminary evidence of feasibility and acceptability of WellPATH. Study participants and therapists reported high satisfaction with WellPATH and provided feedback for future research and development. The patients in the case studies reported a reduction in negative emotions and an increase in emotion regulation (i.e., cognitive reappraisal ability) after using techniques on the WellPATH app.

CONCLUSION

Our preliminary findings suggest that use of technology applications such as the WellPATH app is feasible and accepted among middle-aged and older adults at high suicide risk. Further research with an adequately powered sample is needed to further evaluate WellPATH's feasibility and accessibility, and test its efficacy with this high-risk population.

Understanding Suicide Risk in People with Dementia and Family Caregivers in South Korea: A Systematic Review

Dementia-related suicide is not well known. This study aimed to understand the characteristics of suicide risk among people with dementia and dementia family caregivers in South Korea. According to a systematic review of PRISMA guidelines, six electronic databases were searched for research published from 2010 to 2021. Ten studies were included. Among the included studies on people with dementia, one study (25%) showed no increase in the death risk of suicide, while three studies (75%) revealed suicide risk. Furthermore, in the dementia family caregivers, one study (17%) reported suicides and five studies (83%) reported suicide ideation (SI). Early dementia and independence or partial dependence in activities of daily living and home-based care are related to suicide risk in people with dementia. Meanwhile, suicide risk in dementia family caregivers is related to care burden, dementia severity, and poor approaches to coping with the family member’s dementia. The studies reviewed, which demonstrate heterogenous methodologies, suggest that both people with dementia and dementia family caregivers face suicide risk. The results of the current study offer insights useful for the prevention and treatment of mental health issues in both groups.

[Suicidality in older adults]

Older people have the highest suicide risk compared to all other age groups. Expressions of no longer wanting to live are also found in a large number of older people. The reasons are usually multifactorial and sometimes go back a long way in the personal biography. Limitations resulting from physical illness, mental disorders and social problems make an important contribution. Doctors are often the contact person, even though many older people avoid direct communication in this respect. It is important to perceive and actively address indirect notes, because suicidality is also changeable in very old age. Suicide prevention includes the multimodal treatment of the physical and mental illness, including the (re)activation of resources; however, it also begins in advance, when differentiated images of old age are communicated at the societal level, social participation of older people is practised and the quality of life is maintained until the end.

Prevention of suicidal behavior in older people: A systematic review of reviews

Older people have the highest rates of suicide, yet the evidence base on effective suicide preventions in late-life is limited. This systematic review of reviews aims to synthesize data from existing reviews on the prevention and/or reduction of suicide behavior in late-life and evidence for effectiveness of interventions. A systematic database search was conducted in eight electronic databases from inception to 4/2020 for reviews targeting interventions among adults ≥ 60 to prevent and/or reduce suicide, suicide attempt, self-harm and suicidal ideation. Four high quality reviews were included and interventions categorized as pharmacological (antidepressant use: 239 RCTs, seven observational studies) and behavioral (physical activity: three observational studies, and multifaceted primary-care-based collaborative care for depression screening and management: four RCTs). The 2009 antidepressant use review found significant risk reduction for suicide attempt/self-harm (OR = 0.06, 95% CI 0.01-0.58) and suicide ideation (OR = 0.39, 95% CI 0.18-0.78) versus placebo. The 2015 review found an increased risk of attempts with antidepressants versus no treatment (RR = 1.18, 95% CI 1.10-1.27) and no statistically significant change in suicides versus no treatment (RR = 1.06, 95% CI 0.68-1.66) or ideation versus placebo (OR = 0.52, 95% CI 0.14-1.94). Protective effects were found for physical activity on ideation in 2 out of 3 studies when comparing active versus inactive older people. Collaborative care demonstrated significantly less attempts/ideation (OR = 0.80, 95% CI 0.68-0.94) in intervention group versus usual care. The results of this review of reviews find the evidence inconclusive towards use of antidepressants for the prevention of suicidal behavior in older people, thus monitoring is required prior to start, dosage change or cessation of antidepressants. Evidence to date supports physical activity and collaborative management for reduction of suicide ideation, but additional trials are required for a meta-analysis. To build on these findings, continued high-quality research is warranted to evaluate the effectiveness of interventions in late life.

How spousal physical abuse impacts suicidal ideation among community-dwelling older adults: the effects of protective factors

PURPOSE

The purpose of this study is to examine the impact on suicidal ideation (SI) of having experienced spousal physical abuse and the possible effects of protective factors on the relationship between depressive symptoms and SI among community-dwelling older adults.

METHODS

Using Wisconsin Longitudinal Study data (N = 6,125), a path analysis was conducted to examine the impact of spousal physical abuse on SI and test the possible effects of protective factors.

RESULTS

First, the experience of spousal physical abuse had a significant impact on both depressive symptoms and SI. Second, problem-focused coping, social support, and having a family confidant reduced depressive symptoms directly and mitigated SI indirectly. Third, emotional-focused coping had both direct and indirect effects on depressive symptoms and SI, leading to increases in both. Fourth, although the practical significance may be small, emotional-focused coping worked as a moderator between depressive symptoms and SI.

CONCLUSIONS

Interventions are necessary to increase protective factors and decrease risk factors of depressive symptoms and SI among older adults. In addition, regular screening tests of Intimate Partner Violence, depressive symptoms and SI are recommended.

Nested Case Control Study on the Risk of Suicide Death in Elderly Patients with Pelvic Fractures Using a Nationwide Cohort

Background

The aim of this study was to investigate the incidence rate of suicide deaths in elderly patients with pelvic fractures using a nationwide database and to analyze change in the risk of suicide death overtime after pelvic fractures compared to controls.

Methods

We used the National Health Insurance Service-Senior cohort (NHIS-Senior) of South Korea. Cases and controls were matched for sex, age, history of hospital admission within 1 year, and presence of depression on the date of suicide death. Controls were collected by random selection at a 1 : 5 ratio from patients at risk of becoming cases when suicide cases were collected. Incident pelvic fractures were identified from the NHIS-Senior as follows: first admission during the observational period (2002–2015) to an acute care hospital with a diagnostic code of International Statistical Classification of Diseases and Related Health Problems, 10th revision S321, S322, S323, S324, S325, or S328 and age 65–99 years. Conditional logistic regression analysis was performed to evaluate the association between pelvic fractures and the risk of suicide death.

Results

A total of 2,863 suicide cases and 14,315 controls were identified. Suicide case patients had been more frequently exposed to steroids (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.21–1.45), benzodiazepines (OR, 1.76; 95% CI, 1.61–1.93), and non-steroidal anti-inflammatory drugs (OR, 1.18; 95% CI, 1.07–1.29). Pelvic fractures within 1 year from the date of suicide death were statistically significantly associated with increased risk of suicide (adjusted OR [AOR], 2.65; 95% CI, 1.29–5.45; p = 0.008) compared to controls. The risk of suicide death declined as the incidence date of pelvic fracture was more remote from the date of suicide death: AORs of 2.59 (95% CI, 1.33–5.04; p = 0.005) within 2 years and 2.13 (95% CI, 1.15–3.95; p = 0.017) within 3 years. However, there was no statistical significance in the increased risk of suicide death for pelvic fractures that had occurred ≥ 4 years ago (p > 0.05).

Conclusions

Pelvic fractures in the elderly population increased the risk of suicide death within 3 years, suggesting the need for psychiatric support among elderly patients with pelvic fractures.

Late-life suicide in an aging world

Suicide is an important problem among older adults and in particular older men. Risk factors for suicide in older adults include the loss of a loved one, loneliness and physical illness. Suicide in older adults is often attributed to the development of depression due to bereavement or loss of physical health and independence. However, suicide prevention in old age requires avoiding overly simplistic therapeutic approaches. This Perspective discusses the impact of social determinants of health, cultural narratives and the coronavirus disease 2019 (COVID-19) pandemic on suicide among older adults and proposes strategies for a multifaceted approach to suicide prevention.

Methods and efficacy of social support interventions in preventing suicide: a systematic review and meta-analysis

QUESTION

Suicide is a global public and mental health problem. The effectiveness of social support interventions has not been widely demonstrated in the prevention of suicide. We aimed to describe the methods of social support interventions in preventing suicide and examine the efficacy of them.

STUDY SELECTION AND ANALYSIS

We searched literature databases and conducted clinical trials. The inclusion criteria for the summary of intervention methods were as follows: (1) studies aimed at preventing suicide through method(s) that directly provide social support; (2) use of one or more method(s) to directly provide social support. The additional inclusion criteria for meta-analysis on the efficacy of these interventions included: (1) suicide, suicide attempt or social support-related outcome was measured; (2) randomised controlled trial design and (3) using social support intervention as the main/only method.

FINDINGS

In total, 22 656 records and 185 clinical trials were identified. We reviewed 77 studies in terms of intervention methods, settings, support providers and support recipients. There was a total of 18 799 person-years among the ten studies measuring suicide. The number of suicides was significantly reduced in the intervention group (risk ratio (RR)=0.48, 95% CI 0.27 to 0.85). In 14 studies with a total of 14 469 person-years, there was no significant reduction of suicide attempts in the overall pooled RR of 0.88 (95% CI 0.73 to 1.07).

CONCLUSIONS

Social support interventions were recommended as a suicide prevention strategy for those with elevated suicide risk.

Suicide in late life: A viewpoint

Suicide in old age represents a sad public health concern. Despite the global decline in rates of suicide and the general amelioration of quality of life and access to health care for older adults, their rates of suicide remain the highest virtually in every part of the world. With the aging of the world population and the growing number of mononuclear families, the risk of an increase in isolation, loneliness and dependency does not appear ungrounded. The Covid-19 pandemic is claiming the life of many older persons and creating unprecedented conditions of distress, particularly for this segment of the population. This article briefly examines the main characteristics of suicidal behavior in late life, including observations deriving from the spread of the Sars-2 coronavirus and possible strategies for prevention.

Late Life Depression: The Essentials and the Essential Distinctions

Late life depression (LLD), a familiar syndrome, is not differentiated in the DSM-5. LLD can resemble depressive syndromes in younger adults but it differs in demographic characteristics, phenomenology, prognosis, treatment, suicide risk, relationship to other disorders, and etiology. Older depressed adults often present with fewer major depressive symptoms, less emphasis on mood disturbance, greater preoccupation with somatic or psychotic symptoms, and misleading cognitive deficits. LLD's relationships with medical and neurocognitive symptoms and with inflammatory and immune factors are complex. Formal screening tools and biopsychosocial assessment informs diagnosis and treatment. Evidence supports the effectiveness of lifestyle interventions, several psychotherapies, and a variety of somatic treatment approaches. Comorbid medical disorders must be taken into account when planning treatment. In this article, the authors describe the characteristics of LLD, present an approach to assessment and management, and recommend that future DSM editions include a new specifier to differentiate LLD from other depressive syndromes.

Prevalence of Major Depressive Disorder and Correlates of Thoughts of Death, Suicidal Behaviour, and Death by Suicide in the Geriatric Population-A General Review of Literature

Background: There has been an increase in deaths by suicide in old age in the last decade. Depression and suicide in the elderly, 60 years and above, is a major global public health concern. Determining the prevalence of depression, and correlates of death by suicide in the geriatric population, is an important first step toward addressing this public health concern. This literature review aims to determine the prevalence of major depressive disorders and the correlates of death by suicide in the geriatric population. Methods: This general review of the literature was performed using relevant search terms to determine both the prevalence of depression and the correlates of death by suicide among the geriatric population. Databases such as MEDLINE, PsycINFO, CINAHL, and PubMed were searched. Relevant and current articles were extracted, reviewed, and analyzed. The elderly population was defined as individuals 60 years and above. Only full texts articles in English were reviewed. Findings: The prevalence estimates of major depressive disorder in the elderly ranged from 5.37 to 56%. Adults aged 60 years and older have a high risk of depression that exposes them to suicide. Moreover, elderly women are more likely to experience depression than elderly men, but successful suicide is more common in men. Depression and other mental health conditions (schizophrenia, anxiety disorders) and perceived stress were found to be predictors of suicide in the elderly. Other predictors included physical illnesses such as malignancies, financial constraints, cuckoldry, and sexual dysfunction, and also social factors like living alone triggers depressive symptoms and increases suicidal risk in the elderly. Hanging was found to be the most common method of death by suicide for both sexes. While elderly women preferred poisoning, elderly men in Western countries preferred firearms. Differences in gender, the aging process and social issues were also contributing factors to methods used for suicide. Conclusions: Depression and debilitating physical illnesses were identified as significant contributors to suicide risk in the elderly population, and emphasis should be placed on identifying these factors early and treating them. Recognizing and addressing factors that predict suicide in the elderly will help to improve the mental wellbeing of the elderly.

Development of a Suicide Prediction Model for the Elderly Using Health Screening Data

Suicide poses a serious problem globally, especially among the elderly population. To tackle the issue, this study aimed to develop a model for predicting suicide by using machine learning based on the elderly population. To obtain a large sample, the study used the big data health screening cohort provided by the National Health Insurance Sharing Service. By applying a machine learning technique, a predictive model that comprehensively utilized various factors was developed to select the elderly aged > 65 years at risk of suicide. A total of 48,047 subjects were included in the analysis. Individuals who died by suicide were older, and the number of men was significantly greater. The suicide group had a more prominent history of depression, with the use of medicaments significantly higher. Specifically, the prescription of benzodiazepines alone was associated with a high suicide risk. Furthermore, body mass index, waist circumference, total cholesterol, and low-density lipoprotein level were lower in the suicide group. We developed a model for predicting suicide by using machine learning based on the elderly population. This suicide prediction model can satisfy the performance to some extent by employing only the medical service usage behavior without subjective reports.

Relationship between Willingness and Psychological Characteristics of Suicide Prevention Telephone Counselors: A Retrospective Observational Study

Suicide is a major public health issue worldwide, and telephone counseling is an important preventive measure. As the number of telephone counselors is insufficient in Japan, public needs cannot be fully met. Willingness is important for securing telephone counselors, but few studies have examined the willingness to engage in telephone counseling activities. Therefore, we investigated the relationship between telephone counselors' willingness to perform their activities and their psychological characteristics, health status, and received social support. In this study, a questionnaire survey was conducted by mail among telephone counselors belonging to the Federation of Inochi No Denwa in Japan. The total number of valid responses was 709 (recovery rate: 50.4%). Following an exploratory factor analysis, three factors were extracted: (1) willingness to engage in telephone counseling activities, (2) sense of being burdened by telephone counseling activities, and (3) sense of difficulty in coping. Structural equation modeling, using all the factors, showed that social support and grit were directly related to the willingness to engage in telephone counseling activities, while physical health, mental health, and general self-efficacy were indirectly related to it. The findings obtained may be useful in devising concrete measures for telephone counselors to continue their activities.
