Suicide attempts by poisoning in Hanoi, Vietnam: methods used, mental problems, and history of mental health care

Suicidality Trajectory, Hopelessness, Resilience, and Self-Efficacy Among Patients With Treatment-Resistant Depression in Vietnam

BACKGROUND

Patients with treatment-resistant depression (TRD) have higher rates of suicidal ideation and a higher suicide attempt prevalence than patients with other types of depression.

PURPOSE

This study was designed to study the suicidality trajectory and relationships between hopelessness, resilient coping, and self-efficacy, respectively, and suicidal ideation and suicide attempts in patients with TRD during hospitalization and at 3 months after discharge.

METHODS

A longitudinal survey of 53 psychiatric inpatients with TRD was conducted. Suicidality, hopelessness, resilient coping, self-reported medication adherence, and self-efficacy were assessed at Weeks 1 and 2 (T0 and T1) after hospitalization and Week 1 and Months 1 and 3 after discharge. Data were analyzed using a Cox regression model.

RESULTS

Suicidality varied across the five time points, with a downward trend observed between T0 and T1 (reflecting the initial effects of inpatient treatment) and an upward trend observed across the 3-month follow-up. Antidepressant overdose was the most common method used for suicide. The risk of high suicidal ideation during follow-up was 1.63, 2.63, and 1.14 times higher, respectively, in participants with a high level of hopelessness, low level of resilient coping, and low self-efficacy. Also, having a higher level of hopelessness and being younger in age increased the risk of attempting suicide by 3.07 times and over 6 times, respectively, compared to older participants.

CONCLUSIONS/IMPLICATION FOR PRACTICE

Suicidality was shown to fluctuate between the in-hospital treatment phase and the first 3 months following discharge in this sample of patients with TRD. Younger age, feelings of hopelessness, low resilience, and low self-efficacy were the top four factors contributing to postdischarge suicide risk. These findings highlight the need for regular patient monitoring and assessment to identify those with TRD who are at high risk of suicide as well as the importance of focusing on hopelessness, resilience, and self-efficacy as predictors of suicide ideation and attempts. Nurses should help patients with TRD, especially those who are younger, and improve and maintain their hope, resilience, and self-efficacy both during hospitalization and shortly after discharge.

Psychiatric morbidity and suicidal behaviour in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Psychiatric disorders are reported to be present in 80% to 90% of suicide deaths in high-income countries (HIC), but this association is less clear in low- and middle-income countries (LMIC). There has been no previous systematic review of this issue in LMIC. The current study aims to estimate the prevalence of psychiatric morbidity in individuals with suicidal behaviour in LMIC.

METHODS AND FINDINGS

PubMed, PsycINFO, and EMBASE searches were conducted to identify quantitative research papers (any language) between 1990 and 2018 from LMIC that reported on the prevalence of psychiatric morbidity in suicidal behaviour. We used meta-analytic techniques to generate pooled estimates for any psychiatric disorder and specific diagnosis based on International classification of disease (ICD-10) criteria. A total of 112 studies (154 papers) from 26 LMIC (India: 25%, China: 15%, and other LMIC: 60%) were identified, including 18 non-English articles. They included 30,030 individuals with nonfatal suicidal behaviour and 4,996 individuals who had died by suicide. Of the 15 studies (5 LMIC) that scored highly on our quality assessment, prevalence estimates for psychiatric disorders ranged between 30% and 80% in suicide deaths and between 3% and 86% in those who engaged in nonfatal suicidal behaviour. There was substantial heterogeneity between study estimates. Fifty-eight percent (95% CI 46%-71%) of those who died by suicide and 45% (95% CI 30%-61%) of those who engaged in nonfatal suicidal behaviour had a psychiatric disorder. The most prevalent disorder in both fatal and nonfatal suicidal behaviour was mood disorder (25% and 21%, respectively). Schizophrenia and related disorders were identified in 8% (4%-12%) of those who died by suicide and 7% (3%-11%) of those who engaged in nonfatal suicidal behaviour. In nonfatal suicidal behaviour, anxiety disorders, and substance misuse were identified in 19% (1%-36%) and 11% (7%-16%) of individuals, respectively. This systematic review was limited by the low number of high-quality studies and restricting our searches to databases that mainly indexed English language journals.

CONCLUSIONS

Our findings suggest a possible lower prevalence of psychiatric disorders in suicidal behaviour in LMIC. We found very few high-quality studies and high levels of heterogeneity in pooled estimates of psychiatric disorder, which could reflect differing study methods or real differences. There is a clear need for more robust evidence in order for LMIC to strike the right balance between community-based and mental health focussed interventions.

A survey of Canadian and Australian pharmacists' stigma of suicide

Background

There is limited information available regarding community pharmacists' stigma of suicide. Pharmacists regularly interact with people at risk of suicide and stigmatizing attitudes may impact care.

Objective

To measure community pharmacists' stigma of suicide.

Method

Pharmacists in Canada and Australia completed an online survey with the Stigma of Suicide Scale-Short Form. Data were analysed descriptively and with univariate and multivariate analyses.

Results

Three hundred and ninety-six pharmacists returned completed surveys (Canada n = 235; Australia n = 161; female 70%; mean age = 38.6 ± 12.7 years). The rate of endorsement of stigmatizing terms was low overall. Canadian and Australian pharmacists differed (p < 0.05) for several variables (e.g. age, friend or relative with a mental illness, training in mental health crisis). Pharmacists without someone close to them living with a mental illness were more likely to strongly agree/agree with words describing those who die by suicide as pathetic, stupid, irresponsible, and cowardly. Those without a personal diagnosis of mental illness strongly agreed/agreed with the terms immoral, irresponsible, vengeful, and cowardly. More Australian pharmacists strongly agreed/agreed that people who die by suicide are irresponsible, cowardly, and disconnected. Independent variables associated with a higher stigma were male sex, Australian, and negative perceptions about suicide preventability.

Conclusion

Community pharmacists frequently interact with people at risk of suicide and generally have low agreement of stigmatizing terms for people who die by suicide. Research should focus on whether approaches such as contact-based education can minimize existing stigma.

Evaluation of types of poisoning exposure calls managed by the Malaysia National Poison Centre (2006-2015): A retrospective review

OBJECTIVE

Accidental or intentional poisoning is a public health concern requiring intervention. The current study designs to evaluate the types of poisoning exposure calls received by the Malaysia National Poison Centre (NPC) over a 10-year period.

SETTINGS AND DATA SOURCES

The poisoning enquiries database (2006-2015) from the Malaysia NPC was used for the analysis.

PARTICIPANTS

The NPC records all telephone calls that it manages using a validated and standardised form. Demographics and types of the poisoning exposure calls were extracted and descriptive analysis was applied.

PRIMARY AND SECONDARY OUTCOMES

The primary outcome of this study is to evaluate NPC data for trends in the poisoning exposure calls based on the types and modes of poisoning over a 10-year period. The secondary outcome is to evaluate the characteristics of human exposure cases based on the calls received by the NPC.

RESULTS

There was a notable increase in the number of poisoning exposure calls noticed during the 10-year period but dropped significantly in 2012. The highest number of poisoning exposure calls came from Selangor (21.0%), Perak (18.0%) and Negeri Sembilan (9.8%). More than half of the exposure was intentional (53.8%) involving more women (50.3%) as compared with men (41.9%), and in the 20-29 years age group category (33.5%). Exposure mostly occurred at home (96%) through the ingestion route (94.1%). Pharmaceutical products (40.5%), pesticides (31.7%) and household products (20.1%) were the common agents implicated for intentional exposure.

CONCLUSIONS

There is an increasing trend in enquiries on poisoning exposure calls made to the NPC. Most of the intentional poisoning exposures occurred among younger women and involved pharmaceuticals, pesticides or household products. Poisoning safety education and other interventions are needed to curb poisoning incidents.

The global burden of fatal self-poisoning with pesticides 2006-15: Systematic review

BACKGROUND

Agricultural pesticide poisoning is a major contributor to the global burden of suicide. Over the last decade there has been a marked decrease in the incidence of suicide worldwide. It is unclear whether pesticide poisoning still plays a significant role in the global incidence of suicide.

METHODS

WHO method-specific suicide data were supplemented by a systematic review of the literature between 2006 and 2015, including searches of thirteen electronic databases and Google, citation searching and a review of reference lists and personal collections. Our primary outcome was the proportion of total suicides due to pesticide poisoning. Weighted estimates were calculated for seven WHO regional and income strata.

RESULTS

We identified data from 108 countries (102 from WHO data, 6 from the literature). A conservative estimate based on these data indicates that there were approximately 110,000 pesticide self-poisoning deaths each year from 2010 to 2014, comprising 13.7% of all global suicides. A sensitivity analysis accounting for under-reporting of suicides in India resulted in an increased estimate of 168,000 pesticide self-poisoning deaths annually, that is, 19.7% of global suicides. The proportion of suicides due to pesticide self-poisoning varies considerably between regions, from 0.9% in low- and middle-income countries in the European region to 48.3% in low- and middle-income countries in the Western Pacific region.

LIMITATIONS

High quality method-specific suicide data were unavailable for a number of the most populous countries, particularly in the African and Eastern Mediterranean regions. It is likely we have underestimated incidence in these regions.

CONCLUSION

There appears to have been a substantial decline in fatal pesticide self-poisoning in recent years, largely driven by a reduction in overall suicide rates in China. Nonetheless, pesticide self-poisoning remains a major public health challenge, accounting for at least one-in-seven suicides globally.

Psychiatric disorders in patients presenting to hospital following self-harm: a systematic review

BACKGROUND

Psychiatric disorders occur in approximately 90% of individuals dying by suicide. The prevalence of psychiatric disorders in people who engage in non-fatal self-harm has received less attention.

METHOD

Systematic review using electronic databases (Embase, PsychINFO and Medline) for English language publications of studies in which psychiatric disorders have been assessed using research or clinical diagnostic schedules in self-harm patients of all ages presenting to general hospitals, followed by meta-analyses using random effects methods.

RESULTS

A total of 50 studies from 24 countries were identified. Psychiatric (Axis I) disorders were identified in 83.9% (95% CI 74.7-91.3%) of adults and 81.2% (95% CI 60.9-95.5%) of adolescents and young persons. The most frequent disorders were depression, anxiety and alcohol misuse, and additionally attention deficit hyperactivity disorder (ADHD) and conduct disorder in younger patients. Personality (Axis II) disorders were found in 27.5% (95% CI 17.6-38.7%) of adult patients. Psychiatric disorders were somewhat more common in patients in Western (89.6%, 95% CI 83.0-94.7%) than non-Western countries (70.6%, 95% CI 50.1-87.6%).

LIMITATIONS

Heterogeneity between study results was generally high. There were differences between studies in identification of study participants and diagnostic procedures.

CONCLUSIONS

Most self-harm patients have psychiatric disorders, as found in people dying by suicide. Depression and anxiety disorders are particularly common, together with ADHD and conduct disorder in adolescents. Psychosocial assessment and aftercare of self-harm patients should include careful screening for such disorders and appropriate therapeutic interventions. Longitudinal studies of the progress of these disorders are required.

From pesticides to medicinal drugs: time series analyses of methods of self-harm in Sri Lanka

OBJECTIVE

To explore if recent changes in methods of self-harm in Sri Lanka could explain the decline in the incidence of suicide.

METHODS

Time series analyses of suicide rates and hospitalization due to different types of poisoning were carried out.

FINDINGS

Between 1996 and 2008 the annual incidence of hospital admission resulting from poisoning by medicinal or biological substances increased exponentially, from 48.2 to 115.4 admissions per 100,000 population. Over the same period, annual admissions resulting from poisoning with pesticides decreased from 105.1 to 88.9 per 100,000. The annual incidence of suicide decreased exponentially, from a peak of 47.0 per 100,000 in 1995 to 19.6 per 100,000 in 2009. Poisoning accounted for 37.4 suicides per 100,000 population in 1995 but only 11.2 suicides per 100,000 in 2009. The case fatality rate for pesticide poisoning decreased linearly, from 11.0 deaths per 100 cases admitted to hospital in 1997 to 5.1 per 100 in 2008.

CONCLUSION

Since the mid 1990s, a trend away from the misuse of pesticides (despite no reduction in pesticide availability) and towards increased use of medicinal and other substances has been seen in Sri Lanka among those seeking self-harm. These trends and a reduction in mortality among those suffering pesticide poisoning have resulted in an overall reduction in the national incidence of accomplished suicide.

Suicide attempt in a rural area of Vietnam: Incidence, methods used and access to mental health care

OBJECTIVES

The study aims to determine the incidence of suicide attempt, describe the methods used, and assess use of health care services including mental health care after suicide attempt in a rural area of Vietnam.

METHODS

All suicide attempters (104) during 2003-2007 were listed, diagnosed and re-evaluated by trained physicians according to the research criteria of the WHO Multicentre Study of Attempted Suicide. All attempters were interviewed by trained medical staff to investigate methods used, socio-demographic characteristics and use of health services.

RESULTS

The yearly incidence was 10.2 per 100000 person-years, 10.6 per 100000 in males and 9.8 per 100000 in females. 99% of cases committed suicide attempt by poisoning, 62.6% by pesticides and 36.3% by pharmaceutical drugs. 34.3% reported having been in contact with somatic care and 13.2% had received mental health care. Among those who reported some treatment received, 47.5% had been in contact with official health care services, 8.1% had pharmacy keepers' consultation or were treated by traditional healers and 4% reported self treatment.

CONCLUSION

The incidence of suicide attempt was lower in this population compared to other settings. While the majority of attempters use pesticides, many had used psychotropic drugs. Contact with mental health services following the attempt was very limited in this setting. Suicide prevention for this high risk group should focus on reducing access to pesticides and psychotropic drugs. Mental health services should be made more accessible in rural areas.
