Frequency and clinical features of suicide attempts in elderly patients in Japan

Analysis of attempted suicide episodes presenting to the emergency department: comparison of young, middle aged and older people

Background

Attempted suicide remains difficult for clinicians to predict with some established risk factors. We investigate the detailed characteristics of attempted suicide especially according to age and methods of suicide attempts.

Methods

A retrospective study was conducted to evaluate patients who visited the emergency department due to attempted suicide. A retrospective medical record review of all patients who presented to the emergency department (ED) of two tertiary teaching hospitals in Korea after suicide attempt between January 1, 2010, and December 31, 2017 was performed. Demographic information and detailed variables (methods and reasons of suicide attempts and variables regarding reattempts) were investigated. Total participants were classified into 3 groups according to age, young group, middle aged group and the older group, and each characteristics were compared.

Results

A total of 3698 patients were enrolled in this study. Deliberate self-poisoning (DSP) was the most common method of attempted suicide (66.5%) followed by cutting (24.4%), hanging (7.9%), falling (2.6%), and drowning (1.1%). In patients who had previous suicide attempts (n = 1029, 27.8%), attempted methods were likely to be concordant with previous attempted methods. The most common reason for suicide attempts was interpersonal relationship issues followed by socio-economic reasons. Older patients (n = 412, 11.2%) were significantly different from other 2 groups (n = 3286, 88.8%) regarding gender, suicide re-attempt, occupation, alcohol co-ingestion, previous psychiatric history, and discharge outcomes (all p-values < 0.001). Especially, in older patients, use of critical method and reason of physical illness were more common.

Conclusion

Our findings indicated that people who attempted suicide might have different sociodemographic and clinical factors depending on age group. Depending on age, it is necessary to apply additional suicide intervention programs in different ways.

Chronic obstructive pulmonary disease as a risk factor for suicide: A systematic review and meta-analysis

BACKGROUND

Patients living with chronic obstructive pulmonary disease (COPD) commonly present several limitations in their daily activities, high depression rates, and low quality of life, which makes this population a risk group for suicide. This study aims to systematically assess the literature on the association between CPOD and the likelihood of suicide.

METHODS

The protocol was registered in PROSPERO (CRD42018096618). The Latin-American and Caribbean Health Sciences Literature (LILACS), PubMed, SciELO, Scopus, LIVIVO, Web of Science, and PsychNET databases were used as primary study sources. OpenThesis and OpenGrey were used to partially capture the "grey literature". A manual search was also performed through a systematized analysis of the references of eligible articles. The risk of bias among the studies included was assessed with the Joanna Briggs Institute Critical Appraisal Tools for Systematic Reviews. A random effects meta-analysis was performed to estimate the variation in odds ratio (OR) and 95% confidence intervals (95% CI).

RESULTS

The search provided 4762 results, from which only seven met the eligibility criteria and were ultimately included in the qualitative assessment of the review. The studies were published from 2002 to 2015. All studies presented low risk of bias. The total sample included 1390 suicide cases of COPD patients. The meta-analysis, which was based on five eligible case control studies, found that people with history of COPD are more likely to commit suicide (OR = 1.90; 95% CI = 1.27-2.48; p = 0.002).

CONCLUSION

COPD patients are 1.9 times more likely to commit suicide than people without COPD.

Sociodemographic and clinical characteristics of old-old suicide attempters compared with young-old and middle-aged attempters

OBJECTIVES

The purpose of this study was to identify distinctive characteristics of old-old suicide attempters (75 years and older) from young-old (60-74 years old) and middle-aged suicide attempters (45-59 years old).

METHODS

We included consecutive series of 920 patients aged 45 years and older who had visited the emergency room from 2009 to 2015 because of suicide attempts. They were divided into 3 groups according to age. Information about the suicide attempt and sociodemographic status was gathered through interviews with attempters or caregivers. Chi-square test and logistic regression analysis were performed to evaluate the differences among the 3 groups.

RESULTS

We found that old-old suicide attempters had high intent to die and high medical lethality as a result of the attempt, and illness-related problems exerted a strong motivational effect on this group. Psychiatric drugs, pesticides, and herbicides were frequently used to attempt suicide. These attempts were less likely to be associated with alcohol consumption compared to other age groups.

CONCLUSION

Old-old suicide attempters have different characteristics, compared with young-old and middle-aged counterparts. It is necessary to assess suicide risk and depression when examining patients with physical illness or when prescribing psychotropic drugs. High-risk groups should be given immediate intervention including psychiatric treatment before they act on high suicide intent.

[Suicidality in the elderly: socio-cultural and clinical risk factors]

Advanced age is a significant risk factor for a completed suicide. The review considers the patterns of suicidal behavior of older adults in the context of their gender, ethnicity as well as social and cultural factors. In terms of pro- and antisuicidal variables, special emphasis is made on the role of somatic and psychic disorders. The article looks at the features of committing a suicide peculiar to the older people and debates some specific issues of self-inflicted death by elderly people. The obtained data indicate the involvement of multilevel factors (biological, clinical, cultural, micro- and microsocial) in suicidal behavior in later life.

Mental disorders and suicide attempt in rural China

The prevalence of various mental disorders and their age and gender specific characteristics among suicide attempters remains unclear in rural China. This study using 1:1 paired case-control design included 409 suicide attempters and 409 paired controls matched on age, gender and place of residence. Mental disorders were assessed using the Structured Clinical Interview for DSM-IV-TR Axis I Disorders. The prevalence of mental disorders was 32.3% for suicide attempters and 4.9% for paired controls. Mental disorder constituted a significant risk factor for suicide attempt with an adjusted odds ratio of 7.16 (95%CI: 3.65-14.04). The prevalence of mental disorders was higher among male than female suicide attempters. Major depressive disorder was most common in female suicide attempters while alcohol use disorder was most common in the males. The prevalence of mental disorders seemed to increase with age. Suicide attempters of higher ages were more prone to have mood disorders, especially a major depression. Suicide attempters with mental disorders differed from those without mental disorders on a number of socio-economic characteristics and suicidal behavior features. These insights should be taken into account in strategies and efforts to improve mental health care and ultimately to reduce suicidal behavior among residents in rural China.

Predictors for repeat self-harm and suicide among older people within 12 months of a self-harm presentation

BACKGROUND

A past history of self-harm is a significant risk factor for suicide in older people. The aims of this study are to (i) characterize older people who present with self-harm to emergency departments (EDs); and (ii) determine the predictors for repeat self-harm and suicide.

METHODS

Demographic and clinical data were retrospectively collected on older people (age 65+ years), who presented to seven EDs in New Zealand following an episode of self-harm between 1st July 2010 and 30th June 2013. In addition, 12-month follow-up information on repeat self-harm and suicide was collected.

RESULTS

The sample included 339 older people (55.2% female) with an age range of 65-96 years (mean age = 75.0; SD = 7.6). Overdose (68.7%) was the most common method of self-harm. 76.4% of the self-harm cases were classified as suicide attempts. Perceived physical illness (47.8%) and family discord (34.5%) were the most common stressors. 12.7% of older people repeated self-harm and 2.1% died by suicide within 12 months. Older people who had a positive blood alcohol reading (OR = 3.87, 95% Cl = 1.35-11.12, p = 0.012) and were already with mental health services at the index self-harm (OR = 2.73, 95% Cl = 1.20-6.25, p = 0.047) were more likely to repeat self-harm/suicide within 12 months.

CONCLUSION

Older people who self-harm are at very high risk of repeat self-harm and suicide. Screening and assessment for alcohol use disorders should be routinely performed following a self-harm presentation, along with providing structured psychological treatment as an adjunct to pharmacological treatment for depression and interventions to improve the person's resilience resources.

Tentativas de suicídio entre pessoas idosas: revisão de literatura (2002/2013)

Foi realizada revisão da literatura sobre as principais questões associadas às tentativas de suicídio em pessoas idosas. O estudo abrangeu o período de 2002 a 2013, a partir das bases Medline, Lilacs, PubMed, PsychInfo, SciELO, Biblioteca Virtual em Violência e Saúde da Bireme e Biblioteca Virtual de Saúde Pública (BVS/SP). Foram selecionadas 105 referências e analisadas 75. Os estudos se ampliaram na América do Norte, Europa e Ásia, são raros na América Latina e inexistem na África. Predominam investigações epidemiológicas. Os principais fatores predisponentes são doenças graves e degenerativas, dependência física, distúrbios e sofrimentos mentais e depressão severa. A depressão é o mais relevante fator explicativo associado a sofrimento físico crônico, perdas, abandonos, solidão e conflitos familiares. Diferenças de gênero, etnia, avanço da idade, questões sociais e traços culturais foram encontrados. O tema em pauta é da mais alta relevância para o Sistema Único de Saúde, mas não tem sido abordado no Brasil nem na teoria e nem na prática. Que esta revisão seja base para estudos empíricos que favoreçam o apoio à saúde do idoso e promova um envelhecer saudável.
