Discerning suicide in drug intoxication deaths: Paucity and primacy of suicide notes and psychiatric history

Share of Adult Suicides After Recent Jail Release

Importance

Although people released from jail have an elevated suicide risk, the potentially large proportion of this population in all adult suicides is unknown.

Objective

To estimate what percentage of adults who died by suicide within 1 year or 2 years after jail release could be reached if the jail release triggered community suicide risk screening and prevention efforts.

Design, Setting, and Participants

This cohort modeling study used estimates from meta-analyses and jail census counts instead of unit record data. The cohort included all adults who were released from US jails in 2019. Data analysis and calculations were performed between June 2021 and February 2024.

Main Outcomes and Measures

The outcomes were percentage of total adult suicides within years 1 and 2 after jail release and associated crude mortality rates (CMRs), standardized mortality ratios (SMRs), and relative risks (RRs) of suicide in incarcerated vs not recently incarcerated adults. Taylor expansion formulas were used to calculate the variances of CMRs, SMRs, and other ratios. Random-effects restricted maximum likelihood meta-analyses were used to estimate suicide SMRs in postrelease years 1 and 2 from 10 jurisdictions. Alternate estimate was computed using the ratio of suicides after release to suicides while incarcerated.

Results

Included in the analysis were 2019 estimates for 7 091 897 adults (2.8% of US adult population; 76.7% males and 23.3% females) who were released from incarceration at least once, typically after brief pretrial stays. The RR of suicide was 8.95 (95% CI, 7.21-10.69) within 1 year after jail release and 6.98 (95% CI, 4.21-9.76) across 2 years after release. A total of 27.2% (95% CI, 18.0%-41.7%) of all adult suicide deaths occurred in formerly incarcerated individuals within 2 years of jail release, and 19.9% (95% CI, 16.2%-24.1%) of all adult suicides occurred within 1 year of release (males: 23.3% [95% CI, 20.8%-25.6%]; females: 24.0% [95% CI, 19.7%-36.8%]). The alternate method yielded slightly larger estimates. Another 0.8% of adult suicide deaths occurred during jail stays.

Conclusions and Relevance

This cohort modeling study found that adults who were released from incarceration at least once make up a large, concentrated population at greatly elevated risk for death by suicide; therefore, suicide prevention efforts focused on return to the community after jail release could reach many adults within 1 to 2 years of jail release, when suicide is likely to occur. Health systems could develop infrastructure to identify these high-risk adults and provide community-based suicide screening and prevention.

Youth fatal drug overdose and suicide: Trends in Connecticut, 2019-2021

BACKGROUND AND OBJECTIVES

Increasing rates of fatal drug overdose (FDO) among youth since 2016 have been driven by fentanyl and polysubstance use. Suicide by youth also increased steadily since 2007. The manner of FDO may be accidental (i.e., unintentional) or suicidal (i.e., intentional). This report examines the rate of youth intentional and unintentional FDO as well as specific drug toxicology in Connecticut, between the years 2019 and 2021, compared to a 2016-2018 report.

METHODS

We reviewed N = 286 consecutive FDO files of youth, <26 years of age dated for 2019-2021 from the Connecticut Medical Examiner's office.

RESULTS

FDO attributed to fentanyl increased significantly from 2016 to 2018 to 2019 to 2021. Xylazine FDO emerged in 2019 and reached 16% in 2021. Intentional FDO rates doubled between these periods from 3.8% to 7.7%. Most FDOs involved individuals aged 20-25 years, whereas 10% were among those aged 15-19. For the first time since 2018, FDO among 10-14 years old was detected. Analysis of gender found no differences. Within each gender, however, FDO attributed to fentanyl increased significantly between these periods. The FDO rate for Hispanics increased significantly, while the rate for Whites decreased significantly.

DISCUSSION AND CONCLUSIONS

The availability of high lethality potential drugs leading to youth FDO including an increasing rate of intentional FDO, is a public health concern. It is prudent to identify modifiable acute high-risk circumstances for intentional FDO and prevention-intervention evidence-based approach to reduce FDO.

SCIENTIFIC SIGNIFICANCE

This is the first study of FDO among youth examining the manner of death by suicide.

Racial/ethnic inequality in homelessness and drug overdose deaths in US States

PURPOSE

This study examined whether state-level racial disproportionality in homelessness is associated with racial disproportionality in overdose mortality.

METHODS

Counts of individuals experiencing homelessness (2015-2017; by state and racial/ethnic group) were obtained from the US Department of Housing and Urban Development; population estimates and counts of drug overdose deaths (2018-2021; by state and racial/ethnic group) were obtained from the National Center for Health Statistics. Homelessness and overdose mortality disproportionality scores were calculated to indicate the extent to which each racial group was over- or under- represented among those experiencing homelessness, or among overdose deaths, respectively (relative to each racial group's proportional share in the general population). For each racial group examined, ordinary least squares regression models with robust standard errors (SEs) examined associations between state-level disproportionality in homelessness and disproportionality in overdose mortality, adjusting for percent aged 18-64 and US Census Region, as well as disproportionality in educational attainment and unemployment.

RESULTS

State-level racial disproportionality in homelessness was significantly and positively associated with racial disproportionality in overdose mortality for Black (b = 0.16 [SE = 0.05]; p < .01), American Indian/Alaska Native (b = 0.71 [SE = 0.23]; p < .01), and Hispanic populations (b = 0.17 [SE = 0.05]; p < .01), in models adjusting for region and percent aged 18-64. The significant positive associations in these three populations persisted after adjusting for educational attainment disproportionality, yet the association was no longer significant in the Black population after adjusting for unemployment disproportionality.

CONCLUSION

States with the highest levels of racial/ethnic minority overrepresentation in homelessness generally also had relatively higher levels of racial/ethnic minority overrepresentation in overdose deaths.

Suicide While Locked Up in Texas: Risk Factors for Death by Suicide in Custody

In the United States, suicide is a leading cause of death in prisons and jails, with incarcerated individuals being nine times more likely to die by suicide than the general population. Identifying vulnerabilities at each stage of custody (prebooking, jail, prison) and factors that increase suicide risk can improve prevention efforts. A hierarchical binary logistic regression was conducted on data from the Texas Justice Initiative's Deaths in Custody Report. Variables included race/ethnicity, sex, age at death, days in custody, classification of crime as violent or nonviolent, and custody type of prebooking, jail, or prison. Among main effects, when compared to suicide rates in prison, jail suicide deaths were over three and a half times more likely (OR = 3.61), and the period of prebooking emerged as a period of staggering risk of suicide death, with suicides being over 5,000% more likely than at other stages of custody (OR = 50.86). When interactions were entered, Latinx individuals were at a particularly increased risk of suicide death (OR = 10.46), likelihood of suicide death decreased with each year of age (OR = .89), nonviolent offenders were just under three and a half times more likely to die by suicide when compared to violent offenders (OR = 3.45), and each stage of custody was shown to affect the relationship between age-related rates of suicide in different ways. Results call for further investigation into suicide among understudied populations in corrections, such as Latinx individuals, juveniles in the prison system, and nonviolent offenders, to identify the groups at the highest risk of premature death in correctional systems.

Prevalence and Correlates of Opioid-Involved Suicides in Maryland

OBJECTIVE

Involvement of opioids in suicides has doubled during the past two decades, worsening a major public health concern. This study examined the characteristics of opioid-involved suicides.

METHODS

The sample of decedents (N = 12,038) in Maryland between 2006 and 2020 was used to compare the characteristics of opioid-involved suicides (n = 947) with suicides not involving opioids (n = 6,896) and accidental opioid deaths (n = 4,125). Direct comparisons were then made between opioid-involved suicides with and without the additional presence of non-opioid substances.

RESULTS

Opioid-involved suicides were significantly more likely than suicides not involving opioids to occur among those aged 18-64 years, non-Hispanic Whites, and unemployed or disabled individuals. Opioid-involved suicides were more likely than accidental opioid deaths to occur among females, those aged <18 years, non-Hispanic Whites, and employed individuals. Of all suicides involved opioids, 45% involved other non-opioid substances. Polysubstance opioid suicides were significantly more likely than suicides involving opioids only to occur among non-Hispanic Whites.

CONCLUSIONS

Significant differences were observed in the demographic groups most at risk for opioid-involved suicide than other suicide or accidental opioid death. Among opioid-involved suicides, polysubstance involvement also represents a distinct group. These findings may enhance the targeting of prevention efforts.

The Zero Suicide Model in Addiction Treatment Settings: Recognizing the Need for Feasibility and Implementation Data

The Zero Suicide (ZS) model is a promising approach for preventing all suicides across health care settings. ZS provides guidelines for health care systems to implement best practices in suicide prevention. Patients with substance use disorders are at increased risk for suicide, but no known research has investigated how to integrate the ZS model into addiction treatment settings. This Open Forum encourages clinicians and researchers to integrate ZS into such settings and to study its feasibility and effectiveness. ZS integration into addiction treatment may improve both suicide and addiction outcomes, but additional research is needed.

High dimensional predictions of suicide risk in 4.2 million US Veterans using ensemble transfer learning

We present an ensemble transfer learning method to predict suicide from Veterans Affairs (VA) electronic medical records (EMR). A diverse set of base models was trained to predict a binary outcome constructed from reported suicide, suicide attempt, and overdose diagnoses with varying choices of study design and prediction methodology. Each model used twenty cross-sectional and 190 longitudinal variables observed in eight time intervals covering 7.5 years prior to the time of prediction. Ensembles of seven base models were created and fine-tuned with ten variables expected to change with study design and outcome definition in order to predict suicide and combined outcome in a prospective cohort. The ensemble models achieved c-statistics of 0.73 on 2-year suicide risk and 0.83 on the combined outcome when predicting on a prospective cohort of [Formula: see text] 4.2 M veterans. The ensembles rely on nonlinear base models trained using a matched retrospective nested case-control (Rcc) study cohort and show good calibration across a diversity of subgroups, including risk strata, age, sex, race, and level of healthcare utilization. In addition, a linear Rcc base model provided a rich set of biological predictors, including indicators of suicide, substance use disorder, mental health diagnoses and treatments, hypoxia and vascular damage, and demographics.

Institutional Failures as Structural Determinants of Suicide: The Opioid Epidemic and the Great Recession in the United States

We investigate recent trends in U.S. suicide mortality using a "structural determinants of health" framework. We access restricted-use multiple cause of death files to track suicide rates among U.S. Black, White, American Indian/Alaska Native, and Latino/a men and women between 1990 and 2017. We examine suicide deaths separately by poisonings and nonpoisonings to illustrate that (1) women's suicide rates from poisonings track strongly with increases in prescription drug availability and (2) nonpoisoning suicide rates among all adult Americans track strongly with worsening economic conditions coinciding with the financial crash and Great Recession. These findings suggest that institutional failures elevated U.S. suicide risk between 1990 and 2017 by increasing access to more lethal means of self-harm and by increasing both exposure and vulnerability to economic downturns. Together, these results support calls to scale up to focus on the structural determinants of U.S. suicide.

The temporal association between suicide and comorbid mental disorders in people treated for substance use disorders: a National registry study

BACKGROUND

The time after contact with specialized health services for mental health and substance use is associated with an increased risk of suicide, where temporal aspects of suicide and comorbid mental disorders in patients with substance use disorders could be associated. This study aimed to examine the temporal association between time from last treatment contact to suicide and comorbid mental disorders in patients with substance use disorders.

METHODS

This study is a historical prospective case series using nationwide registry data. It included 946 individuals registered the year before suicide with a substance use disorder (F10-F19) in Norway's specialized health services for treating substance use and mental health disorders between 2010 and 2020. The outcome was the number of weeks from the last contact with services to suicide. The exposure was comorbid mental disorders divided into 'no comorbid mental disorder'; 'psychosis or bipolar disorders' (F20-F31), 'depressive or anxiety disorders' (F32-F49); and 'personality disorders' (F60-F69). Covariates included gender, age, last diagnosed substance use disorder, registered deliberate self-harm last year, and the number of in- and outpatient contacts the previous year.

RESULTS

The number of weeks from last service contact to suicide differed (p =  < 0.001) between patients with no comorbid mental disorders (Median = 7; IQR 2-23), psychosis or bipolar disorders (Median = 2; IQR = 1-7), depressive or anxiety disorders (Median = 3; IQR = 1-11) and personality disorders (Median = 1; IQR = 1-5.5). Significantly decreased adjusted incidence rate ratios (aIRR) were found for psychosis or bipolar disorders [aIRR = 0.67 (95% CI 0.53-0.85)] and personality disorders [aIRR = 0.56 (0.42-0.77)] compared to no comorbid mental disorder when adjusted for individual characteristics and service contact. For depressive and anxiety disorders compared to no comorbid mental disorder, the association was significant when adjusted for individual characteristics [aIRR = 0.55 (0.46-0.66)].

CONCLUSIONS

While patients with substance use disorders generally died by suicide a short time after contact with services, patients with comorbid mental disorders died an even shorter time after such contact and significantly shorter than patients without such comorbidities.

Physical Health Problems as a Suicide Precipitant: Associations With Other Risk Factors and Suicide Methods in Three Age Groups of Older Decedents

Background and Objectives

Physical health problems are a significant late-life suicide precipitant. This study's purpose was to examine differences in (i) other suicide precipitants and psychiatric/substance use problems, and (ii) suicide methods (firearms, hanging/suffocation, and poisoning) in 3 age groups (55-64, 65-74, and 75+) of older suicide decedents who had physical health problems as a suicide precipitant.

Research Design and Methods

Data came from the 2017-2019 U.S. National Violent Death Reporting System (N = 34,912; 27,761 males [79.5%] and 7,151 females [20.5%]). Generalized linear models for a Poisson distribution with a log link were used to examine the study questions.

Results

Physical health problems were a suicide precipitant for 25.8%, 41.9%, and 57.7% of the 55-64, 65-74, and 75+ age groups, respectively, and were associated with a higher likelihood of having had depressed mood (IRR = 1.38, 95% CI: 1.33-1.43) and other substance use problems (IRR = 1.22, 95% CI: 1.13-1.31). Interaction effects showed that when job/finance/housing problems, depressed mood, or any psychiatric disorders were co-present with physical health problems, the age group differences in the predicted rates of physical health problems were diminished. Physical health problems were also positively associated with firearm and poisoning use, but negatively associated with hanging/suffocation. Interaction effects indicated that the predicted rates of firearm and poisoning use significantly increased among those aged 55-64 with than without physical health problems.

Discussion and Implications

In all 3 age groups of older suicide decedents, physical health problems were the predominant suicide precipitant, and those with physical health problems had elevated depressed mood. Assessment of suicide risk, affordable and accessible health, and mental health services, restriction of access to lethal suicide methods, and policy-based suicide prevention approaches for older adults with physical health problems are needed.

COVID-19-Related Suicides-Public Health Role of Forensic Pathologists

ABSTRACT

Concerns about potential increases in suicidal behavior during the coronavirus disease 2019 (COVID-19) pandemic arose in response to reported widespread mental health deterioration. Although early data did not corroborate such concerns, suicide remains a significant cause of preventable deaths worldwide and is of significant interest to public health in the setting of a pandemic. In this study, we present 17 cases of COVID-19-related suicides seen in our West Michigan Medical Examiner's office from 2020 to 2022, which exhibit the complex relationship between mental health and pandemic-related psychological, social, and economic stressors. The relationships were generally categorized as increased anxiety and/or stress due to COVID-19 (5/17 [29.4%]), the loss of social support and/or social isolation occurring as a result of COVID-19 restrictions (5/17 [29.4%]), financial concerns or loss of income as a result of COVID-19 policies (3/17 [17.6%]), grief related specifically to COVID-19 (2/17 [11.8%]), and purported neuropsychiatric sequelae of a prior COVID-19 infection (2/17 [11.8%]). By examining these cases, we highlight ways in which public health systems might prepare for and respond to mental health crises during current or future pandemics and the need for increased collaboration between forensic pathologists and epidemiologists in collating high-quality data during death investigations.

Deliberate Self-Poisoning: Real-Time Characterization of Suicidal Habits and Toxidromes in the Food and Drug Administration Adverse Event Reporting System

INTRODUCTION

Deliberate self-poisoning (DSP) using drugs is the preferred method of suicide at a global level. Its investigation is hampered by limited sample sizes and data reliability. We investigate the role of the US FDA Adverse Event Reporting System (FAERS), a consolidated pharmacovigilance database, in outlining DSP habits and toxidromes.

METHODS

We retrieved cases of 'intentional overdose' and 'poisoning deliberate' from the FAERS (January 2004-December 2021). Using descriptive and disproportionality analyses, we estimated temporal trends, potential risk factors, toxidromes, case-fatality rates and lethal doses (LDs) for the most frequently reported drugs.

RESULTS

We retrieved 42,103 DSP cases (17% fatal). Most cases were submitted in winter. Reports of DSP involved younger people, psychiatric conditions, and alcohol use, compared with non-DSP, and fatality was higher in men and older patients. Suspected drugs were mainly antidepressants, analgesics, and antipsychotics. Multiple drug intake was recorded in more than 50% of the reports, especially analgesics, psychotropics, and cardiovascular agents. The most frequently reported drugs were paracetamol, promethazine, amlodipine, quetiapine, and metformin. We estimated LD25 for paracetamol (150 g).

CONCLUSION

Worldwide coverage of the FAERS complements existing knowledge about DSP and may drive tailored prevention measures to timely address the DSP phenomenon and prevent intentional suicides.

Escalating costs of self-injury mortality in the 21st century United States: an interstate observational study

BACKGROUND

Estimating the economic costs of self-injury mortality (SIM) can inform health planning and clinical and public health interventions, serve as a basis for their evaluation, and provide the foundation for broadly disseminating evidence-based policies and practices. SIM is operationalized as a composite of all registered suicides at any age, and 80% of drug overdose (intoxication) deaths medicolegally classified as 'accidents,' and 90% of corresponding undetermined (intent) deaths in the age group 15 years and older. It is the long-term practice of the United States (US) Centers for Disease Control and Prevention (CDC) to subsume poisoning (drug and nondrug) deaths under the injury rubric. This study aimed to estimate magnitude and change in SIM and suicide costs in 2019 dollars for the United States (US), including the 50 states and the District of Columbia.

METHODS

Cost estimates were generated from underlying cause-of-death data for 1999/2000 and 2018/2019 from the US Centers for Disease Control and Prevention's (CDC's) Wide-ranging ONline Data for Epidemiologic Research (WONDER). Estimation utilized the updated version of Medical and Work Loss Cost Estimation Methods for CDC's Web-based Injury Statistics Query and Reporting System (WISQARS). Exposures were medical expenditures, lost work productivity, and future quality of life loss. Main outcome measures were disaggregated, annual-averaged total and per capita costs of SIM and suicide for the nation and states in 1999/2000 and 2018/2019.

RESULTS

40,834 annual-averaged self-injury deaths in 1999/2000 and 101,325 in 2018/2019 were identified. Estimated national costs of SIM rose by 143% from $0.46 trillion to $1.12 trillion. Ratios of quality of life and work losses to medical spending in 2019 US dollars in 2018/2019 were 1,476 and 526, respectively, versus 1,419 and 526 in 1999/2000. Total national suicide costs increased 58%-from $318.6 billion to $502.7 billion. National per capita costs of SIM doubled from $1,638 to $3,413 over the observation period; costs of the suicide component rose from $1,137 to $1,534. States in the top quintile for per capita SIM, those whose cost increases exceeded 152%, concentrated in the Great Lakes, Southeast, Mideast and New England. States in the bottom quintile, those with per capita cost increases below 70%, were located in the Far West, Southwest, Plains, and Rocky Mountain regions. West Virginia exhibited the largest increase at 263% and Nevada the smallest at 22%. Percentage per capita cost increases for suicide were smaller than for SIM. Only the Far West, Southwest and Mideast were not represented in the top quintile, which comprised states with increases of 50% or greater. The bottom quintile comprised states with per capita suicide cost increases below 24%. Regions represented were the Far West, Southeast, Mideast and New England. North Dakota and Nevada occupied the extremes on the cost change continuum at 75% and - 1%, respectively.

CONCLUSION

The scale and surge in the economic costs of SIM to society are large. Federal and state prevention and intervention programs should be financed with a clear understanding of the total costs-fiscal, social, and personal-incurred by deaths due to self-injurious behaviors.

County-level predictors of US drug overdose mortality: A systematic review

BACKGROUND

This systematic review summarized published literature on county-level predictors of drug overdose mortality in the United States (US).

METHODS

Peer-reviewed studies and doctoral dissertations published in English between 1990 and July 19, 2022 were identified from PubMed, Web of Science, ProQuest Dissertations & Theses, PsycINFO, CINAHL, and EconLit. Eligible studies examined at least one county-level predictor of drug overdose mortality in US counties. Two reviewers independently completed screening, quality assessment (with an adapted National Institutes of Health Quality Assessment Tool), and data extraction. Results were qualitatively summarized and grouped by predictor categories.

RESULTS

Of 56 studies included, 42.9% were subnational, and 53.6% were limited to opioid overdose. In multiple studies, measures related to opioid prescribing, illness/disability, economic distress, mining employment, incarceration, family distress, and single-parent families were positively associated with drug overdose mortality outcomes, while measures related to cannabis dispensaries, substance use treatment, social capital, and family households were negatively associated with drug overdose mortality outcomes. Both positive and negative associations were documented for smoking, uninsurance, healthcare professional shortage status, physicians per capita, unemployment, income, poverty, educational attainment, racial composition, and rurality. Findings within studies also differed by subpopulation (by race/ethnicity, gender, age, or rurality) and the type of drugs involved in overdose.

CONCLUSIONS

The findings of this review provide relatively mixed evidence regarding many county-level predictors of overdose mortality, several of which also vary between subpopulations, supporting the importance of additional research to elucidate pathways through which the county context may shape risk of fatal overdose.

Detection of Suicide Clusters using Small-Area Geographic Data from the Virginia Violent Death Reporting System, 2010 - 2015

Introduction

From 1999 to 2020, the suicide rate in Virginia increased from 13.1 to 15.9 per 100,000 persons aged 10 years and older. Few studies have examined spatial patterns of suicide geographies smaller than the county level.

Methods

We analyzed data from suicide decedents aged ≥10 years from 2010 through 2015 in the Virginia Violent Death Reporting System. We identified spatial clusters of high suicide rates using spatially adaptive filtering with standardized mortality ratio (SMR) significantly higher than the state SMR (p < 0.001). We compared demographic characteristics, method of injury, and suicide circumstances of decedents within each cluster to decedents outside any cluster.

Results

We identified 13 high-risk suicide clusters (SMR between 1.7 and 2.0). Suicide decedents in the clusters were more likely to be older (40+ years), non-Hispanic white, widowed/divorced/separated, and less likely to have certain precipitating suicide circumstances than decedents outside the clusters. Suicide by firearm was more common in four clusters, and suicide by poisoning was more common in two clusters compared to the rest of the state.

Conclusions

There are important differences between geographic clusters of suicide in Virginia. These results suggest that place-specific risk factors for suicide may be relevant for targeted suicide prevention.

Differences in overdose deaths by intent: Unintentional & suicide drug poisonings in North Carolina, 2015-2019

Comprehensive fatal overdose prevention requires an understanding of the fundamental causes and context surrounding drug overdose. Using a social determinants of health (SDOH) framework, this descriptive study examined unintentional and self-inflicted (i.e., suicide) overdose deaths in North Carolina (NC), focusing on specific drug involvement and contextual factors. Unintentional and suicide overdose deaths were identified using 2015-2019 NC death certificate data. Specific drug involvement was assessed by searching literal text fields for drug mentions. County-level contextual factors were obtained from NC Institute of Medicine and County Health Rankings, encompassing five SDOH domains (economic stability, social/community context, health care access/quality, education access/quality, neighborhood/built environment). Descriptive statistics were calculated by intent for drug involvement and a variety of contextual factors. During 2015-2019, 9% of NC drug overdose deaths were self-inflicted and 89% were unintentional (2% other/undetermined). Unintentional overdoses largely involved illicit drugs [fentanyl (47%), cocaine (33%), heroin (29%)]. Suicide overdoses frequently involved prescription opioids [oxycodone (18%), hydrocodone (10%)] and antidepressants (32%). Overall, overdose deaths tended to occur in under-resourced counties across all SDOH domains, though unintentional overdoses occurred more often among residents of under-resourced counties than suicide overdoses, with differences most pronounced for economic stability-related factors. There are notable distinctions between unintentional and suicide overdose deaths in demographics and drug involvement, though the assessment of SDOH demonstrated that overdose mortality is broadly associated with marginalization across all domains. These findings highlight the value of allocating resources to prevention and intervention approaches that target upstream causes of overdose (e.g., housing first, violence prevention programs).

Job loss, financial strain, and housing problems as suicide precipitants: Associations with other life stressors

Previous research has shown that job loss, financial strain, and/or loss of housing (JFH) in midlife elevate suicide risk. In this study based on the 2017–2019 National Violent Death Reporting System, we examined other suicide precipitants and contributors of decedents whose suicide was in part precipitated by JFH and the circumstances under which they died. First, we examined all adult decedents (N = 94,454; 74,042 males [78.4%] and 20,412 females [21.6%]) and then focused on decedents age 45–64 (N = 34,208; 25,640 males [75%] and 8568 females [25.0%]). The 45–64 age group had the highest rate of JFH (22.0% for males and 15.1% for females) as a suicide precipitant. The results of generalized linear models for all adult suicide decedents of both sexes showed that the 45–64 age group (IRR = 2.02, 95% CI = 1.89–2.16), compared to 65+ age group, and relationship problems, mental disorders, and alcohol problems were associated with significantly higher risk of JFH-precipitated suicide. In male decedents age 45–64, JFH was positively associated with depressed mood (IRR = 1.95, 95% CI = 1.85–2.06), alcohol problems (IRR = 1.14, 95% CI = 1.07–1.21), and number of crises (IRR = 1.48, 95% CI = 1.43–1.53). In female decedents age 45–64, JFH was positively associated with relationship problems (IRR = 1.19, 95% CI = 1.05–1.35), legal problems (IRR = 1.27, 95% CI = 1.06–1.54), depressed mood (IRR = 1.78, 95% CI = 1.59–1.99), and number of crises (IRR = 1.58, 95% CI = 1.48–1.68). In both sexes, the risk of JFH was also positively associated with a college education. In female decedents, JFH risk was higher among divorced or never-married individuals. Coroner/medical examiner and law enforcement agency reports show that some experienced depression and started misusing alcohol and/or other substances following a job loss, but others had these problems throughout life, which caused/contributed to JFH. These findings show the significance of suicide prevention approaches at both systemic (generous unemployment insurance, housing subsidies) and individual (treatment of depression and alcohol/substance misuse problems and social support/connection) levels.

•

16.2% of male and 13.0% of female suicide decedents age 18+ in 2017–2019 had job/finance/housing problems (JFH).

•

Among decedents age 45–64, 22.0% of male and 15.1% of female had JFH.

•

JFH was positively associated with number of crises, depressed mood, and relationship and alcohol problems in both sexes.

•

Suicide prevention approaches are needed at both systemic and individual levels.

Distinguishing clinical factors associated with unintentional overdose, suicidal ideation, and attempted suicide among opioid use disorder in-patients

Opioid and other drug-related overdoses and suicides are leading causes of injury death and represent a significant public health threat in the United States (U.S.). This study examined clinical factors of three patient groups from two inpatient addiction treatment facilities in Appalachian West Virginia (n = 66). Patients were classified as having: 1) unintentional overdose(s) (OD), 2) suicidal ideation or suicide attempt(s) (SI/SA), and 3) suicidal ideation or suicide attempt, and unintentional overdose (SI/SA/OD). Multinomial logistic regression models were used to determine whether adverse childhood experiences, self-injurious behaviors, substance use history, overdose history, and past year stressful life events were differentially associated with history of SI/SA/OD. Participants in the OD group were more likely to have used heroin in the 24-h preceding their most recent overdose compared to either the SI/SA or SI/SA/OD groups. The multivariable model found participants with history of SI/SA had higher adverse childhood experience scores and more participants with history of SI/SA endorsed childhood physical abuse and teen dating violence. Overall, there are characteristics that distinguish unintentional overdose from suicidal ideation and attempt. Patients with SI/SA/OD appear to have greater clinical severity. More thorough evaluation of drugs involved in overdose and history of self-injury may help distinguish future risk and inform treatment planning.

Using natural language processing to improve suicide classification requires consideration of race

OBJECTIVES

To improve the accuracy of classification of deaths of undetermined intent and to examine racial differences in misclassification.

METHODS

We used natural language processing and statistical text analysis on restricted-access case narratives of suicides, homicides, and undetermined deaths in 37 states collected from the National Violent Death Reporting System (NVDRS) (2017). We fit separate race-specific classification models to predict suicide among undetermined cases using data from known homicide cases (true negatives) and known suicide cases (true positives).

RESULTS

A classifier trained on an all-race dataset predicts less than half of these cases as suicide. Importantly, our analysis yields an estimated suicide rate for the Black population comparable with the typical detection rate for the White population, indicating that misclassification excess is endemic for Black suicide. This problem may be mitigated by using race-specific data. Our findings, based on the statistical text analysis, also reveal systematic differences in the phrases identified as most predictive of suicide.

CONCLUSIONS

This study highlights the need to understand the reasons underlying suicide rate differences and for further testing of strategies to reduce misclassification, particularly among people of color.

Achieving health equity in US suicides: a narrative review and commentary

Suicide rates in the United States (US) reached a peak in 2018 and declined in 2019 and 2020, with substantial and often growing disparities by age, sex, race/ethnicity, geography, veteran status, sexual minority status, socioeconomic status, and method employed (means disparity). In this narrative review and commentary, we highlight these many disparities in US suicide deaths, then examine the possible causes and potential solutions, with the overarching goal of reducing suicide death disparities to achieve health equity.

The data implicate untreated, undertreated, or unidentified depression or other mental illness, and access to firearms, as two modifiable risk factors for suicide across all groups. The data also reveal firearm suicides increasing sharply and linearly with increasing county rurality, while suicide rates by falls (e.g., from tall structures) decrease linearly by increasing rurality, and suicide rates by other means remain fairly constant regardless of relative county urbanization. In addition, for all geographies, gun suicides are significantly higher in males than females, and highest in ages 51–85 + years old for both sexes. Of all US suicides from 1999–2019, 55% of male suicides and 29% of female suicides were by gun in metropolitan (metro) areas, versus 65% (Male) and 42% (Female) suicides by gun in non-metro areas. Guns accounted for 89% of suicides in non-metro males aged 71–85 + years old. Guns (i.e., employment of more lethal means) are also thought to be a major reason why males have, on average, 2–4 times higher suicide rates than women, despite having only 1/4—1/2 as many suicide attempts as women. Overall the literature and data strongly implicate firearm access as a risk factor for suicide across all populations, and even more so for male, rural, and older populations.

To achieve the most significant results in suicide prevention across all groups, we need 1) more emphasis on policies and universal programs to reduce suicidal behaviors, and 2) enhanced population-based strategies for ameliorating the two most prominent modifiable targets for suicide prevention: depression and firearms.

Profiles of Patients with Opioid Use Disorders Presenting a History of Suicidal Ideations and Attempts

Suicide rates are higher for people with an opioid use disorder, compared to the general population. This study aims to characterize opioid agonist treatment entrants who present a history of suicidal ideations or suicide attempts, according to concurrent comorbidity profiles, in an opioid use disorder treatment facility. A chart review design was used. Data was collected from 202 patient files. Bivariate and multivariate analyses were conducted. In multivariate analysis, patients with a diagnosis or symptoms of a mood disorder were 2.48 [1.01 - 6.11] times more likely to report suicidal ideations and 2.64 [1.05 - 6.62] times more likely to report suicide attempts. Those with a diagnosis or symptoms of an anxiety disorder were 2.41 [1.01 - 5.81] times more likely to report suicidal ideations. Patients who report chronic pain were 2.59 [1.06 - 6.35] times more likely to report suicidal ideations as well. The probability to report suicide attempts was 5.09 [1.16 - 22.4] times higher for those with a confirmed or suspected personality disorder. Clinicians should bear in mind the high suicide rates in people with opioid use disorder, as well as the importance of addressing suicidal risk and providing easy access to mental health and chronic pain treatment as part of the service offer in opioid agonist treatment. Future research should focus on evaluating the effectiveness of treatments aimed at addressing the needs of opioid agonist treatment patients with interrelated mental health and pain comorbidity profiles to reduce risks associated with suicide.

Suicidal motivations among opioid overdose survivors: Replication and extension

BACKGROUND

Several studies suggest suicidal motivation may contribute to opioid overdose fatalities in people with opioid use disorder. In this study, we sought to replicate and extend prior findings suggesting that a desire to die is common prior to nonfatal opioid overdose in people with opioid use disorder.

METHODS

Adults receiving inpatient detoxification and stabilization who reported a history of opioid overdose (N = 60) completed questions about suicidal cognition prior to their most recent overdose.

RESULTS

Approximately 45% reported some desire to die prior to their most recent overdose, with 20% reporting they had some intention to die. The correlation between these ratings was of a moderate magnitude (ρ = 0.58). Almost 40% of the sample perceived no risk of overdose prior to their most recent overdose event, suggesting a significant underestimation of risk in this population.

CONCLUSIONS

Desire to die was common in adults with opioid use disorder prior to nonfatal opioid overdose events, and 1 in 5 people with a history of opioid overdose reported intention to die prior to their most recent opioid overdose. Careful assessment of suicidal cognition in this population may improve prevention of opioid overdose deaths.

Integrating topic modeling and word embedding to characterize violent deaths

We introduce an approach to identify latent topics in large-scale text data. Our approach integrates two prominent methods of computational text analysis: topic modeling and word embedding. We apply our approach to written narratives of violent death (e.g., suicides and homicides) in the National Violent Death Reporting System (NVDRS). Many of our topics reveal aspects of violent death not captured in existing classification schemes. We also extract gender bias in the topics themselves (e.g., a topic about long guns is particularly masculine). Our findings suggest new lines of research that could contribute to reducing suicides or homicides. Our methods are broadly applicable to text data and can unlock similar information in other administrative databases.

There is an escalating need for methods to identify latent patterns in text data from many domains. We introduce a method to identify topics in a corpus and represent documents as topic sequences. Discourse atom topic modeling (DATM) draws on advances in theoretical machine learning to integrate topic modeling and word embedding, capitalizing on their distinct capabilities. We first identify a set of vectors (“discourse atoms”) that provide a sparse representation of an embedding space. Discourse atoms can be interpreted as latent topics; through a generative model, atoms map onto distributions over words. We can also infer the topic that generated a sequence of words. We illustrate our method with a prominent example of underutilized text: the US National Violent Death Reporting System (NVDRS). The NVDRS summarizes violent death incidents with structured variables and unstructured narratives. We identify 225 latent topics in the narratives (e.g., preparation for death and physical aggression); many of these topics are not captured by existing structured variables. Motivated by known patterns in suicide and homicide by gender and recent research on gender biases in semantic space, we identify the gender bias of our topics (e.g., a topic about pain medication is feminine). We then compare the gender bias of topics to their prevalence in narratives of female versus male victims. Results provide a detailed quantitative picture of reporting about lethal violence and its gendered nature. Our method offers a flexible and broadly applicable approach to model topics in text data.

Initiation of Opioid Prescription and Risk of Suicidal Behavior Among Youth and Young Adults

BACKGROUND AND OBJECTIVES

Opioids are involved in an increasing proportion of suicide deaths. This study examined the association between opioid analgesic prescription initiation and suicidal behavior among young people.

METHODS

We analyzed Swedish population-register data on 1 895 984 individuals ages 9 to 29 years without prior recorded opioid prescriptions. We identified prescriptions dispensed from January 2007 onward and diagnosed self-injurious behavior and death by suicide through December 2013. We first compared initiators with demographically matched noninitiators. To account for confounding, we applied an active comparator design, which examined suicidal behavior among opioid initiators relative to prescription nonsteroidal antiinflammatory drug (NSAID) initiators while inverse-probability-of-treatment weighting with individual and familial covariates.

RESULTS

Among the cohort, 201 433 individuals initiated opioid prescription. Relative to demographically matched noninitiators, initiators (N = 180 808) had more than doubled risk of incident suicidal behavior (hazard ratio = 2.64; 95% confidence interval [CI], 2.47-2.81). However, in the active comparator design, opioid initiators (N = 86 635) had only 19% relatively greater risk of suicidal behavior compared with NSAID initiators (N = 255 096; hazard ratio = 1.19; 95% CI,: 1.11-1.28), corresponding to a weighted 5-year cumulative incidence of 2.2% (95% CI, 2.1-2.4) for opioid and 1.9% (95% CI, 1.9-2.0) for NSAID initiators. Most sensitivity analyses produced comparable results.

CONCLUSIONS

Opioid initiation may make only a small contribution to the elevated risk of suicidal behavior among young people receiving pharmacologic pain management. In weighing benefits and harms of opioid initiation, our results suggest that increased risk of suicidal behavior may not be a major concern.

Bagge C, Jasilionis D, Kaplan MS, Meščeriakova-Veliulienė O, Štelemėkas M, Probst C. Comparing gender-specific suicide mortality rate trends in the United States and Lithuania, 1990-2019: putting one of the "deaths of despair" into perspective

INTRODUCTION

The increase in the suicide mortality rate among middle-aged adults in the United States (US) has been well documented. Aside from a few studies from the United Kingdom, it is unclear whether the suicide mortality rate trend in the US is also occurring in other developed countries. Accordingly, we aimed to compare the suicide mortality rate trends over the past 30 years in the US to a country in the European Union-Lithuania.

METHODS

Joinpoint regression analyses were performed to identify secular trends in the gender-specific age-standardized suicide mortality rate among individuals 15 + years of age, as well as middle-aged adults (45-54 years of age), and suicide mortality rate ratio for men-to-women.

RESULTS

Age-standardized suicide mortality rates among middle-aged adults in the US increased annually, on average, by 0.89% (95% CI: 0.66%, 1.12%) among men and 1.21% (95% CI: 0.75%, 1.66%) among women between 1990 and 2019. In contrast to the US, there was an overall downward trend in the suicide mortality rates among middle-aged adults in Lithuania across the study period. The average annual percent change in the suicide mortality rate ratio for men-to-women were not statistically significant for either country.

CONCLUSION

The suicide mortality rate trend in the US does not appear to be an indicator of an upcoming global trend, but rather should be regarded as a cautionary example of what other countries should strive to avoid.

The Psychoanalytic Study of Suicide, Part I: An Integration of Contemporary Theory and Research

Psychodynamic psychotherapy has an important role in suicide prevention. The psychoanalytic study of suicide has taught us a great deal about the human experience and the process of suicidality. There is also much to be learned from other fields of study and from empirical research that can be integrated into psychoanalytic therapies. Central to the psychoanalytic approach to suicide has been understanding the patient's internal subjective experience of unbearable emotional or psychic pain and the urgent need for relief. Emotional pain can include intense affects such as shame, humiliation, self-hate, and rage. Factors that can increase vulnerability to suicidal states include problems with early attunement, dissociation and deficits in bodily love and protection, conscious and unconscious fantasy, and certain character traits and dynamics. Empirical research has confirmed many basic psychoanalytic concepts about suicide, including escape from unbearable pain as the primary driver of suicidal behavior, the role of dissociation in increasing risk of bodily attack, and the importance of unconscious processes. Further research into implicit processes and their role in the suicidal process holds potential to improve suicide risk assessment and to enhance psychotherapy by bringing otherwise inaccessible material into the treatment.

Association of State Social and Environmental Factors With Rates of Self-injury Mortality and Suicide in the United States

IMPORTANCE

Self-injury mortality (SIM) combines suicides and the preponderance of drug misuse-related overdose fatalities. Identifying social and environmental factors associated with SIM and suicide may inform etiologic understanding and intervention design.

OBJECTIVE

To identify factors associated with interstate SIM and suicide rate variation and to assess potential for differential suicide misclassification.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used a partial panel time series with underlying cause-of-death data from 50 US states and the District of Columbia for 1999-2000, 2007-2008, 2013-2014 and 2018-2019. Applying data from the Centers for Disease Control and Prevention, SIM includes all suicides and the preponderance of unintentional and undetermined drug intoxication deaths, reflecting self-harm behaviors. Data were analyzed from February to June 2021.

EXPOSURES

Exposures included inequity, isolation, demographic characteristics, injury mechanism, health care access, and medicolegal death investigation system type.

MAIN OUTCOMES AND MEASURES

The main outcome, SIM, was assessed using unstandardized regression coefficients of interstate variation associations, identified by the least absolute shrinkage and selection operator; ratios of crude SIM to suicide rates per 100 000 population were assessed for potential differential suicide misclassification.

RESULTS

A total of 101 325 SIMs were identified, including 74 506 (73.5%) among males and 26 819 (26.5%) among females. SIM to suicide rate ratios trended upwards, with an accelerating increase in overdose fatalities classified as unintentional or undetermined (SIM to suicide rate ratio, 1999-2000: 1.39; 95% CI, 1.38-1.41; 2018-2019: 2.12; 95% CI, 2.11-2.14). Eight states recorded a SIM to suicide rate ratio less than 1.50 in 2018-2019 vs 39 states in 1999-2000. Northeastern states concentrated in the highest category (range, 2.10-6.00); only the West remained unrepresented. Least absolute shrinkage and selection operator identified 8 factors associated with the SIM rate in 2018-2019: centralized medical examiner system (β = 4.362), labor underutilization rate (β = 0.728), manufacturing employment (β = -0.056), homelessness rate (β = -0.125), percentage nonreligious (β = 0.041), non-Hispanic White race and ethnicity (β = 0.087), prescribed opioids for 30 days or more (β = 0.117), and percentage without health insurance (β = -0.013) and 5 factors associated with the suicide rate: percentage male (β = 1.046), military veteran (β = 0.747), rural (β = 0.031), firearm ownership (β = 0.030), and pain reliever misuse (β = 1.131).

CONCLUSIONS AND RELEVANCE

These findings suggest that SIM rates were associated with modifiable, upstream factors. Although embedded in SIM, suicide unexpectedly deviated in proposed social and environmental determinants. Heterogeneity in medicolegal death investigation processes and data assurance needs further characterization, with the goal of providing the highest-quality reports for developing and tracking public health policies and practices.

Individual and County-Level Disparities in Drug and Opioid Overdose Mortality for Hispanic Men in Massachusetts and the Northeast United States

BACKGROUND

This study aimed to identify individual- and county-level inequalities that may underlie disparities in drug overdose mortality for Hispanic men in Massachusetts and the broader Northeast region.

METHODS

The study first used data from the State Unintentional Drug Overdose Reporting System to compare the 635 Hispanic and 3593 Non-Hispanic (NH) White men who died of unintentional/undetermined opioid-related overdoses in Massachusetts in 2016-2018. Next, the study used 2015-2019 data from the Multiple Cause of Death online platform to: a) compare rates of drug overdose mortality in Hispanic versus NH White men in 54 counties in the Northeast United States; and b) examine associations with inequalities in poverty, educational attainment, unemployment, and uninsurance (from 2015-2019 American Community Survey data).

RESULTS

At the individual level, in Massachusetts, Hispanic and NH White men who died of opioid-related overdose differed in terms of educational attainment, birthplace, urbanicity, substance use disorder treatment history, and specific drugs involved in death. At the county level, in the Northeast region, each one-standard deviation increase in the ratio of the Hispanic to NH White poverty rate was associated with a 27% increase in the ratio of Hispanic to NH White male overdose mortality; each one-standard deviation increase in the ratio of the Hispanic to NH White unemployment rate was associated with a 43% increase in the ratio of Hispanic to NH White male overdose mortality.

CONCLUSIONS

Findings underscore the importance of equitable interventions and efforts to address inequalities in social determinants of health for Hispanic populations in the Northeast.

Unintentional and intentional drug poisoning deaths, Australia, 2012-2016: Drug pattern profile and demographic characteristics

BACKGROUND

Identifying differences in unintentional versus intentional drug poisoning deaths can inform targeted prevention. This study aimed to: compare unintentional versus intentional drug poisoning deaths by drug involvement, age and sex; describe patterns of drug involvement by intent; and describe common drug patterns by age and sex.

METHODS

Cases comprised deaths among Australians aged ≥15 where drug poisoning was the underlying cause (Cause of Death Unit Record File 2012-2016). Sex, age, and drug involvement were analysed by intent using logistic regression.

RESULTS

Of 7994 deaths, 71% were unintentional and 24% intentional. Compared with unintentional deaths, intentional deaths were more likely among females (OR 1.31 [95% CI 1.16-1.48]) and those aged 55+ (1.50 [1.25-1.81] for 55-64 years; 3.79 [3.07-4.66] for 65+ years, compared to 35-44 years), and were more likely to involve hypnosedatives (2.11 [1.87-2.39]), other psychotropic medicines (1.58 [1.39-1.78]), non-opioid analgesics and anaesthetics (1.48 [1.25-1.73]). Common unintentional profiles comprised: opioids (excluding heroin); heroin; alcohol; opioids with hypnosedatives; opioids with hypnosedatives and other psychotropic medicines; stimulants; other psychotropic medicines; and opioids with other psychotropic medicines. Unintentional deaths involving heroin or stimulants only had a greater proportion of males (79.0% and 83.4%, respectively) and younger individuals aged 15-34 (30.3% and 39.5%, respectively). Common intentional profiles comprised: hypnosedatives; other psychotropic medicines; opioids (excluding heroin); hypnosedatives with other psychotropic medicines; opioids with hypnosedatives; and opioids with hypnosedatives and other psychotropic medicines.

CONCLUSION

The demographic and drug involvement profile of intentional and unintentional deaths were distinct, suggesting different approaches to prevention are necessary.

Fentanyl and other opioid involvement in methamphetamine-related deaths

BACKGROUND

Methamphetamine-related deaths have been rising along with those involving synthetic opioids, mostly fentanyl and fentanyl analogs (FAs). However, the extent to which methamphetamine involvement in deaths differs from those changes occurring in synthetic opioid involvement is unknown.

OBJECTIVES

To determine the patterns and temporal changes in methamphetamine-related deaths with and without other drug involvement.

METHODS

Data from all methamphetamine-related deaths in West Virginia from 2013 to 2018 were analyzed. Quasi-Poisson regression analyses over time were conducted to compare the rates of change in death counts among methamphetamine and fentanyl//FA subgroups.

RESULTS

A total of 815 methamphetamine-related deaths were analyzed; 572 (70.2%) were male and 527 (64.7%) involved an opioid. The proportion of methamphetamine only deaths stayed relatively flat over time although the actual numbers of deaths increased. Combined fentanyl/FAs and methamphetamine were involved in 337 deaths (41.3%) and constituted the largest increase from 2013 to 2018. The modeling of monthly death counts in 2017-2018 found that the average number of deaths involving fentanyl without methamphetamine significantly declined (rate of change -0.025, p < .001), while concomitant fentanyl with methamphetamine and methamphetamine only death counts increased significantly (rate of change 0.056 and 0.057, respectively, p < .001).

CONCLUSIONS

Fentanyl and FAs played an increasingly significant role in methamphetamine-related deaths. The accelerating number of deaths involving fentanyl/FAs and methamphetamine indicates the importance of stimulants and opioids in unintentional deaths. Comprehensive surveillance efforts should continue to track substance use patterns to ensure that appropriate prevention programs are undertaken.

The contribution of method choice to gender disparity in suicide mortality: A population-based study in Hong Kong and the United States of America

BACKGROUND

In most countries, more females than males attempt suicide, yet suicide mortality is typically higher for males. The aim of this study was to investigate how suicide method choice contributed to gender disparity in suicide mortality.

METHODS

This study used population-based data collected in Hong Kong (HK) and the United States of America (USA) (2007-2014), comprising suicide deaths and medically treated suicide attempts. We calculated suicide rates, suicide act rates, and case fatality rates (CFRs), by gender and suicide method in HK and the USA respectively. Decomposition analysis was used to quantify the contribution of gender differences in method choice and method-specific CFRs to the excess male suicide rates in each region.

RESULTS

Gender disparity in suicide mortality was mostly driven by gender differences in method used in suicide acts. In HK, gender difference in choosing jumping as the method in suicide acts explained 44.5% of the gender imbalance in suicide rates, whilst in USA, 62.4% of male excess in suicide rates was explained by gender difference in using firearms in suicide acts.

LIMITATIONS

Cases of suicide attempts in this study were restricted to those severe enough to require medical attention.

CONCLUSION

Gender-specific suicide method choice largely determined gender patterns in suicide. Our findings highlighted the importance of developing locally tailored suicide prevention strategies targeting commonly used and highly lethal suicide methods. Future research is needed to explore underlying reasons for gender differences in method choice.

Suicide by Opioid: Exploring the Intentionality of the Act

Opioid toxicity can result in life-threatening respiratory depression. Opioid-overdose mortality in the United States is high and increasing, but it is difficult to determine what proportion of those deaths might actually be suicides. The exact number of Americans who died of an opioid overdose but whose deaths might be classified as suicide remains unknown. It is important to differentiate between those who take opioids with the deliberate and unequivocal objective of committing suicide, that is, those with active intent, from those with passive intent. The passive-intent group understands the risks of opioid consumption and takes dangerous amounts, but with a more ambiguous attitude toward suicide. Thus, among decedents of opioid overdose, a large population dies by accident, whereas a small population dies intending to commit suicide; but between them exists a sub-population with equivocal intentions, waxing and waning between their desire to live and the carelessness about death. There may be a passive as well as active intent to commit suicide, but less is known about the passive motivation. It is important for public health efforts aimed at reducing both suicides and opioid-use disorder to better understand the range of motivations behind opioid-related suicides and how to combat them.

Epidemiological Characteristics of Sedative-Hypnotics and Opioid Painkillers at High-Frequency Exposure

Drug poisoning has a high incidence and serious consequences in medical institutions; its epidemiological characteristics also directly affect the changes in national laws and policies and the implementation of local management policies. Chinese statistics on drug-related abnormal death cases generally come from judicial appraisal centers and medical units. However, due to differences in work content and professional restrictions, there are differences in information management forms, which makes it difficult for appraisers to conduct a professional and systematic analysis of drug-related cases. This article focuses on the analysis of epidemiological characteristics of sedative-hypnotics and opioid painkillers and their exposure patterns in cases of poisoning death by analyzing the annual report of the American Association of Poison Control Center, combined with the characteristics of drug exposure in China.

Suicide as a hidden contributor to the opioid crisis and the role that primary care and emergency medicine play in addressing it

Deaths from overdose have risen dramatically over the past decade, driven mainly by opioids. In response, the Centers for Disease Control and Prevention released guidance on safe prescribing, safe storage of medications, Medication-Assisted Treatment (MAT), and the use of Naloxone to reverse an overdose. Even with this guidance, overdose deaths continue to rise. Suicide prevention is a strategy that may help address this problem. Suicide rose 32.4% between 1999 and 2019, from 10.5 to 13.9 per 100,000. Closely linked to overdose, the suicide rate among those with opioid use disorder is 87 per 100,000 population, six times that of the general US population. With multiple shared individual-level risk factors, strict standards for case ascertainment, and high potential for misclassification of opioid suicides, the distinction between overdose and suicide is often unclear, and the number of suicides is likely underestimated. The Surgeon General recently released a call to action for a public health approach to suicide prevention. Primary care and emergency departments have a major role to play. This commentary describes suicide as a hidden contributor to the opioid crisis; the rationale for integration of suicide prevention in primary care and emergency departments; and screening, education, brief intervention, and follow up and monitoring techniques that these settings can employ. Done effectively, this strategy has the potential to save countless lives.

Inconsistencies in Overdose Suicide Death Investigation Practice and Potential Remedies Using Technology: A Centers for Disease Control and Prevention Consultation Meeting Summary

INTRODUCTION

It is widely accepted that suicides-which account for more than 47 500 deaths per year in the United States-are undercounted by 10% to 30%, partially due to incomplete death scene investigations (DSI) and varying burden-of-proof standards across jurisdictions. This may result in the misclassification of overdose-related suicides as accidents or undetermined intent.

METHODS

Virtual and in-person meetings were held with suicidologists and DSI experts from five states (Spring-Summer 2017) to explore how features of a hypothetical electronic DSI tool may help address these challenges.

RESULTS

Participants envisioned a mobile DSI application for cell phones, tablets, or laptop computers. Features for systematic information collection, scene description, and guiding key informant interviews were perceived as useful for less-experienced investigators.

DISCUSSION

Wide adoption may be challenging due to differences in DSI standards, practices, costs, data privacy and security, and system integration needs. However, technological tools that support consistent and complete DSIs could strengthen the information needed to accurately identify overdose suicides.

Spain's suicide statistics: do we believe them?

PURPOSE

There is a widespread belief that suicides around the world are under-counted. A substantial proportion of suicides may have been inappropriately registered as accidental or of undetermined cause or intent. There is reason to explore to what extent low suicide rates in some nations could be partly attributable to under-counting.

METHODS

Mortality statistics of most countries are available on-line. Numbers of suicide deaths in Spain, and in England and Wales (E & W), in male and female 5-year age groups, in each year between 2014 and 2018, were documented, along with deaths coded to ICD-10 accident or 'undetermined death' categories. Crude mortality rates were calculated using official population figures. Single year suicide, undetermined death, and non-transport accidental death rates of 12 other nations were calculated.

RESULTS

Spain's crude suicide rate per 100,000 remains low (7.89) compared to other nations; its event of undetermined intent (EUI) death rate was 0.09 (contrasting with E & W's 1.74). Its accidental poisoning rate is much lower than that of E & W. The study showed much higher rates of ill-defined/unknown cause deaths in late life in Spain (both genders) than in E & W, and age-associated increases in accidental drowning rates parallel with increased suicide by drowning.

CONCLUSIONS

Reportedly low suicide rates in Spain could be partly attributable to increased rates of 'hidden suicide' (accidental drowning, male accidental poisoning, and possibly ill-defined/unknown cause deaths, but not EUIs). It would be appropriate (and not just in Spain) to increase numbers of verbal and/or forensic autopsies in questionable 'undetermined' cases.

Physician Suicide in the United States:Updated Estimates from the National Violent Death Reporting System

Physician suicide and well-being are critical issues but studies use varying methodologies and suicide is frequently underreported. This study sought to update data on physician suicides in the United States. The National Violent Death Reporting System (NVDRS) at the Centers for Disease Control collects details about violent deaths. The study used 2010-2015 data from 27 NVDRS states to identify suicide deaths among physicians or non-physicians and calculate annual standardized mortality rates (SMR). Of 63,780 victims total, there were 357 physicians identified over 6 years, (307 men and 50 women). If results are extrapolated to all 50 states, there would be approximately 119 physician suicides annually. The SMR for physicians overall was not statistically different from that of non-physicians. This is the first study in 16 years to update estimated physician suicide rates in the United States. The research used strict criteria to identify physicians so results likely represent the lower boundary of physician suicides. Findings show that physician suicide is not significantly lower than that of non-physicians and emphasizes the importance of focusing on structural changes to reduce stigma around mental health in the medical community.

Postmortem screening of opioids, benzodiazepines, and alcohol among rural and urban suicide decedents

PURPOSE

Fatal suicides involving opioids are increasingly common, particularly in rural areas. As co-use of opioids with other substances contributes significantly to mortality risk, we examined whether positive screens for opioids with other substances is more prevalent among rural versus urban suicide deaths, as this could have implications for public health strategies to reduce overdose suicides.

METHODS

Data from all states reporting opioid-related overdose suicides in the National Violent Death Reporting System from 2012 to 2015 were used. Relative risk ratios were obtained using multinomial logistic regression, comparing opioid-only to (1) opioid and alcohol, (2) opioid and benzodiazepines, and (3) opioid, alcohol, and benzodiazepines suicides across rurality. Models were fit using robust standard errors and fixed effects for year of death, adjusting for individual, county, and state-level covariates.

FINDINGS

There were 3,781 opioid-overdose suicide decedents (42% female) tested for all 3 substances during the study period. Unadjusted prevalence of positive screens in decedents varied across rurality (P = .022). Urban decedents were more likely to test positive for opioids alone, while rural decedents were more to likely test positive for opioids and benzodiazepines.

CONCLUSIONS

Rural suicides are associated with increased opioid and benzodiazepine positive screens. These findings suggest the need for rural-focused interventions to support appropriate co-prescribing, better health education for providers about risks associated with drug mixing, and more linkages with mental health services.

Suicide safer care in behavioral health settings: A comparative analysis of perceptions, training completion, and practice between mental health and substance use disorder treatment providers

BACKGROUND

Despite prevention and treatment efforts, opioid overdose deaths continue to rise in the United States and totaled 46,802 in 2018. This public health crisis is closely linked with suicide, with those who misuse opioids at six times the risk of death by suicide. Suicide prevention in substance use disorder (SUD) treatment may be a critical step in saving lives and promoting recovery among those at risk for opioid overdose.

METHODS

We distributed an electronic survey to clinicians in mental health and SUD treatment in nine health systems across New York State from November 2018 to January 2019. The goal of the survey was to assess attitudes, perceptions, practice, and training needs among SUD treatment providers and how they differ from those of mental health providers.

RESULTS

A total of 633 clinicians responded to the survey (62.4% response rate). Seventy-one percent of SUD providers reported working with a client who attempted suicide. Even so, less than half of SUD providers reported routinely screening new (48.9%) or existing patients (25.6%) for suicidal thoughts/behaviors; overall, 28.4% of SUD providers reported low levels of action to address suicide risk, compared to 9.0% of mental health providers (p < 0.001). Perceived self-efficacy and effectiveness at reducing a patient's risk of suicide and training completion were strongly associated with routine delivery of suicide safer care in adjusted logistic regression models.

CONCLUSIONS

The results of this study identify key areas for targeted training and technical assistance to increase the provision of quality suicide safer care in SUD treatment.

Fatal self-injury in the United States, 1999-2018: Unmasking a national mental health crisis

BACKGROUND

Suicides by any method, plus 'nonsuicide' fatalities from drug self-intoxication (estimated from selected forensically undetermined and 'accidental' deaths), together represent self-injury mortality (SIM)-fatalities due to mental disorders or distress. SIM is especially important to examine given frequent undercounting of suicides amongst drug overdose deaths. We report suicide and SIM trends in the United States of America (US) during 1999-2018, portray interstate rate trends, and examine spatiotemporal (spacetime) diffusion or spread of the drug self-intoxication component of SIM, with attention to potential for differential suicide misclassification.

METHODS

For this state-based, cross-sectional, panel time series, we used de-identified manner and underlying cause-of-death data for the 50 states and District of Columbia (DC) from CDC's Wide-ranging Online Data for Epidemiologic Research. Procedures comprised joinpoint regression to describe national trends; Spearman's rank-order correlation coefficient to assess interstate SIM and suicide rate congruence; and spacetime hierarchical modelling of the 'nonsuicide' SIM component.

FINDINGS

The national annual average percentage change over the observation period in the SIM rate was 4.3% (95% CI: 3.3%, 5.4%; p<0.001) versus 1.8% (95% CI: 1.6%, 2.0%; p<0.001) for the suicide rate. By 2017/2018, all states except Nebraska (19.9) posted a SIM rate of at least 21.0 deaths per 100,000 population-the floor of the rate range for the top 5 ranking states in 1999/2000. The rank-order correlation coefficient for SIM and suicide rates was 0.82 (p<0.001) in 1999/2000 versus 0.34 (p = 0.02) by 2017/2018. Seven states in the West posted a ≥ 5.0% reduction in their standardised mortality ratios of 'nonsuicide' drug fatalities, relative to the national ratio, and 6 states from the other 3 major regions a >6.0% increase (p<0.05).

INTERPRETATION

Depiction of rising SIM trends across states and major regions unmasks a burgeoning national mental health crisis. Geographic variation is plausibly a partial product of local heterogeneity in toxic drug availability and the quality of medicolegal death investigations. Like COVID-19, the nation will only be able to prevent SIM by responding with collective, comprehensive, systemic approaches. Injury surveillance and prevention, mental health, and societal well-being are poorly served by the continuing segregation of substance use disorders from other mental disorders in clinical medicine and public health practice.

FUNDING

This study was partially funded by the National Centre for Injury Prevention and Control, US Centers for Disease Control and Prevention (R49CE002093) and the US National Institute on Drug Abuse (1UM1DA049412-01; 1R21DA046521-01A1).

An emergency department medical record review for adolescent intentional self-harm injuries

BACKGROUND

Non-suicidal self-injury and suicide attempts are increasing problems among American adolescents. This study developed a definition for identifying intentional self-harm (ISH) injuries in emergency department (ED) records coded with International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes. The definition is based on the injury-reporting framework proposed by the Centers for Disease Control and Prevention. The study sought to estimate the definition's positive predictive value (PPV), and the proportion of ISH injuries with intent to die (i.e., suicide attempt).

METHODS

The study definition, based on first-valid external cause-of-injury ICD-10-CM codes X71-X83, T14.91, T36-T65, or T71, captured 207 discharge records for initial encounters for ISH in one Kentucky ED. Medical records were reviewed to confirm provider-documented diagnosis for ISH, and identify intent to die or suicide ideation. The PPV of the study definition for capturing provider-documented ISH injuries was reported with its 95% confidence interval (95% CI).

RESULTS

The estimated PPV for the study definition to capture ISH injuries was 88.9%, 95% CI (83.8%, 92.8%). The estimated percentage of ISH with intent to die was 45.9, 95% CI (47.1, 61.0%). The ICD-10-CM code "suicide attempt" (T14.91) captured only 7 cases, but coding guidelines restrict assignment of this code to cases in which the mechanism of the suicide attempt is unknown.

CONCLUSIONS

The proposed case definition supported a robust PPV for ISH injuries. Our findings add to the evidence that the current ICD-10-CM coding system and coding guidelines do not allow identification of ISH with intent to die; modifications are needed to address this issue.

Racial/Ethnic Differences in Preceding Circumstances of Suicide and Potential Suicide Misclassification Among US Adolescents

PURPOSE

There is a paucity of research on racial/ethnic differences in preceding circumstances of suicide among adolescents aged 10-19 years and consequential potential misclassification of suicide deaths (i.e., manner of death classified as injury of undetermined intent). This study (1) examined preceding circumstances of suicide among non-Hispanic White, non-Hispanic Black, non-Hispanic Asian/Pacific Islander (A/PI), non-Hispanic American Indian/Alaskan Native (AI/AN), and Hispanic adolescent decedents; and (2) investigated potential suicide misclassification of racial/ethnic minority decedents.

METHODS

We used data from the 2006-2015 National Violent Death Reporting System Restricted Access Database. Multivariable logistic regression analyses examined differences in depressed mood, mental health problem and treatment, crisis in the past 2 weeks, problems with school, intimate partner, family relationship, and other relationships (e.g., friend) among racial/ethnic minority decedents compared to White decedents. A separate logistic regression analysis assessed potential suicide misclassification of racial/ethnic minority decedents relative to White counterparts.

RESULTS

Adjusting for sex and suicide history and circumstances, all racial/ethnic minority decedents had significantly lower odds of documented mental health problem and treatment compared to White decedents. Racial/ethnic differences in relationship problems were also identified. Black decedents had significantly higher odds of manner-of-death classification as undetermined intent than did White decedents, suggesting greater likelihood of suicide misclassification.

CONCLUSIONS

Circumstances contributing to suicide among adolescents differ by race/ethnicity, indicating the need for culturally tailored suicide prevention efforts.

Variable Circumstances of Suicide Among Racial/Ethnic Groups by Sex and Age: A National Violent-Death Reporting System Analysis

Suicide rates vary by race/ethnicity, but little is known about how the circumstances that contribute to suicide differ across racial/ethnic groups. This study investigated suicide circumstances among non-Hispanic Whites, non-Hispanic Blacks, non-Hispanic Asian/Pacific Islanders, non-Hispanic Native American/Alaskan Natives, and Hispanics by sex and age. Using de-identified National Violent Death Reporting System (NVDRS) Restricted Access Database files from 2006-2015, we examined proximal circumstances of suicide among decedents aged 10 years and older. Hierarchical logistic regression analysis revealed racial/ethnic differentials in non-alcohol substance abuse problem, intimate partner problem, and physical health problem across sex and age, controlling for potential confounders. Study findings highlight priority areas for suicide interventions.

Evidence for Underregistration of Suicide

In this case report, we will present two cases in which the Dutch municipal coroner registered a natural death, but treating psychiatrists doubted the validity of this decision on the grounds of clinical data and investigation. For both cases, we present evidence that deaths likely resulted from suicide, raising serious doubts about the accuracy of the registered cause of death. According to the WHO bulletin on suicide prevention, the national registration of suicide is unsatisfactory in many countries. The Netherlands is listed by the WHO as having one of the most accurate registration procedures. Nevertheless, there are indications that national registration, even in the Dutch system, is not infallible. In this case report, we present several ways in which the registration process is liable to error and evidence for underregistration of suicide rates.

The Affordable Care Act Young Adult Mandate and Suicidal Behavior

This article aimed to determine the association between the Affordable Care Act young adult mandate and suicidal behavior. From 2007 to 2013, we used the Nationwide/National Inpatient Sample and National Poison Data System to examine suicide attempt, and Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research to examine suicide. We aggregated each outcome by quarter/year and conducted a difference-in-differences linear regression to compare young adults aged 19 to 25 years with those 27 to 29 years before and after implementation. There were not statistically significant associations between the mandate and suicide attempt inpatient hospitalizations (unstandardized beta coefficient [b] = -0.72, p = .12, standard error [SE] = 0.42) and percentage of poisoning cases due to suspected suicidal intent (b = 0.23, p = .19, SE = 0.16). There was a statistically significant association when examining suicide prevalence (b = -0.03, p = .01, SE = 0.001). The results suggest that health insurance may buffer against but is unlikely to reverse the increasing suicide rate.

Overcoming the limitations of 'accident' as a manner of death for drug overdose mortality: case for a death certificate checkbox

Collectively, the epidemic increases in the United States of opioid-related deaths and suicides during the first two decades of the 21st century have exposed shortcomings in current forensic and epidemiological approaches for determining and codifying manner of death-a vital function fulfilled by medical examiners, coroners and nosologists-the foundation for the National Violent Death Reporting System (NVDRS), an incident-based surveillance system providing individual-level information on decedent characteristics, manner, cause and circumstances of suicide, homicide and other violent injury deaths. Drug intoxication deaths are generally classified as 'accidents' or unintentional, a fundamental mischaracterisation; most arose from repetitive self-harm behaviours related to substance acquisition and misuse. Moreover, given the burden of affirmative evidence required to determine suicide, many of these 'accidents' likely reflected unrecognised intentional acts-that is, suicides. Addition of a simple checkbox for self-injury mortality on the death certificate would enrich the National Death Index and NVDRS, and in turn, inform prevention and clinical research, and enhance the evaluation of prevention programmes and therapeutic regimens.

Humanitarian reason and the movement for overdose prevention sites: The NGOization of the Opioid "Crisis"

In August 2017, a group of activists erected in Ottawa's downtown a tent as a first overdose prevention site as a response to what the public and the activists perceived as an epidemic-a devastating wave of opioid and fentanyl overdoses in Canada. The Ontario premier was urged to declare an emergency that would provide increased funding for harm reduction and also send a message to survivors and families that the lives of their loved ones mattered. Thus, the discourses around the so-called opioid crisis used a language of moral sentiments to legitimate political action. This "new humanitarianism" is considered a priori as good, but in this article, I ask what is politically at stake if we base our actions on the logic of humanitarian reason. The new universalism of humanitarian organizations is based on the individualism of human rights and thus on a moral imperative that replaces the political. Initiatives like the OPS movement often fill the gaps in social services in the absence of the state and address social problems as emergencies and public health issues, thereby transforming them into medical problems-performing the medicalization of sociopolitical problems. This is what I call the NGOization of the opioid crisis. This form of humanitarianism is a universalism of the temporal present without any universal promise for a better future or the amelioration of human conditions-it is a humanitarianism of emergency. What characterizes new humanitarianism is that it responds to situations of suffering that are the result of increasing inequality and injustices without addressing the root causes of this suffering. Not addressing these causes means to be complicit in perpetuating the inequalities and to restrict visions of possible alternatives.

Links between suicidal intent, polysubstance use, and medical treatment after non-fatal opioid overdose

BACKGROUND

Suicidal thinking during non-fatal overdose may elevate risk for future completed suicide or intentional overdose. Long-term outcomes following an intentional non-fatal overdose may be improved through specific intervention and prevention responses beyond those designed for unintentional overdoses, yet little research has assessed suicidal intent during overdoses or defined characteristics that differentiate these events from unintentional overdoses.

METHODS

Patients with a history of opioid overdose (n = 274) receiving residential addiction treatment in the Midwestern United States completed self-report surveys to classify their most recent opioid overdose as unintentional, actively suicidal (wanted to die), or passively suicidal (didn't care about the risks). We characterized correlates of intent using descriptive statistics and prevalence ratios. We also examined how intent related to thoughts of self-harm at the time of addiction treatment.

RESULTS

Of opioid overdoses, 51 % involved suicidal intent (44 % passive and 7 % active). Active suicidal intent was positively associated with hospitalization. Active/passive intent (vs. no intent, aPR: 2.2, 95 % CI: 1.4-3.5) and use of ≥5 substances (vs. 1 substance, aPR: 3.6, 95 % CI: 1.2-10.6) at the last opioid overdose were associated with having thoughts of self-harm or suicide in the 2 weeks before survey completion in adjusted models. Participants who reported active/passive intent more commonly used cocaine or crack (27 %) with opioids during their last overdose relative to unintentional overdoses (16 %).

CONCLUSIONS

Over half of opioid overdoses among individuals in addiction treatment involved some degree of suicidal thinking. Identifying patients most at risk will facilitate better targeting of suicide prevention and monitoring services.
