An exploration of human services system contacts prior to suicide in South Carolina: an expansion of the South Carolina Violent Death Reporting System

Research utility and limitations of textual data in the National Violent Death Reporting System: a scoping review and recommendations

BACKGROUND

Many studies of injury deaths rely on mortality data that contain limited contextual information about decedents. The National Violent Death Reporting System (NVDRS) is unique among such data systems in that each observation includes both quantitative variables and qualitative texts (called "narratives") abstracted from original source documents. These narratives provide rich data regarding salient circumstances that can be used to inform prevention efforts. This review provides a comprehensive summary of peer-reviewed research using NVDRS narratives over the past 20 years, including the limitations of these texts and provides recommendations on utilizing and improving narrative quality for researchers and practitioners.

MAIN BODY

Studies that used narratives to examine deaths related to suicide, homicide, undetermined intent, accidental firearm, or legal intervention were identified by a title/abstract screening, followed by a full-text review. The search was conducted on English-language, peer-reviewed literature and government reports published from 2002 to 2022 in PubMed, PsycInfo, Scopus, and Google Scholar. Abstracted elements focused on the methodologies used to analyze the narratives, including approaches to explore potential biases in these texts. Articles were abstracted independently by two reviewers, with disagreements resolved through consensus discussion. During the 20-year period, 111 articles used narratives. Two-thirds studied suicide (n = 48, 43%) and homicides (n = 25, 23%). Most studies analyzed the narratives using manual review (n = 81, 73%) and keyword searches (n = 9, 8%), with only 6 (5%) using machine learning tools. Narratives were mainly used for case finding (n = 49, 44%) and characterization of circumstances around deaths (n = 38, 34%). Common challenges included variability in the narratives and lack of relevant circumstantial details for case characterization.

CONCLUSION

Although the use of narratives has increased over time, these efforts would be enhanced by detailed abstraction of circumstances with greater salience to injury research and prevention. Moreover, researchers and practitioners would benefit from guidance on integrating narratives with quantitative variables and standardized approaches to address variability in the completeness and length of narratives. Such efforts will increase the reliability of findings and set the stage for more widespread applications of data science methods to these texts.

Estimating the association between mental health disorders and suicide: a review of common sources of bias and challenges and opportunities for US-based research

Purpose of review

The purpose of this review is to 1) illuminate prevalent methodological approaches and estimates of association between mental health diagnoses and suicide from the meta-analytic literature; 2) discuss key internal and external validity concerns with these estimates; and 3) highlight some of the unique attributes and challenges in US-based suicide research and opportunities to move the evidence base forward.

Recent findings

Globally, there is considerable variability in measures of association between mental health disorders and suicide and a growing debate over methodological approaches to this research. A high suicide incidence makes the US an outlier, and the decentralized nature of US administrative data poses a unique challenge to data linkage that could otherwise advance this research.

Summary

We offer methodological considerations for future research and discuss opportunities made possible by the recent expansion of the US National Violent Death Reporting System to a nationwide registry.

Contact with primary and mental health care prior to suicide: A systematic review of the literature from 2000 to 2017

Aim: To examine rates of contact with primary and mental health care prior to suicide in men and women and across a range of age categories. Method: The authors performed a systematic review of 44 studies from 2000 to 2017 of which 36 reported rates on contact with primary health care and 14 reported on contact with mental health care prior to suicide. Results: Contact with primary health care was highest in the year prior to suicide with an average contact rate of 80%. At one month, the average rate was 44%. The lifetime contact rate for mental health care was 57%, and 31% in the final 12 months. In general, women and those over 50 years of age had the highest rates of contact with health care prior to suicide. Conclusions: Contact with primary health care prior to suicide is common even in the final month before death. The findings presented in this study highlight the importance of placing suicide prevention strategies and interventions within the primary health care setting.

National Trends in Suicide Attempts Among Adults in the United States

Importance

A recent increase in suicide in the United States has raised public and clinical interest in determining whether a coincident national increase in suicide attempts has occurred and in characterizing trends in suicide attempts among sociodemographic and clinical groups.

Objective

To describe trends in recent suicide attempts in the United States.

Design, Setting, and Participants

Data came from the 2004-2005 wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and the 2012-2013 NESARC-III. These nationally representative surveys asked identical questions to 69 341 adults, 21 years and older, concerning the occurrence and timing of suicide attempts. Risk differences adjusted for age, sex, and race/ethnicity (ARDs) assessed trends from the 2004-2005 to 2012-2013 surveys in suicide attempts across sociodemographic and psychiatric disorder strata. Additive interactions tests compared the magnitude of trends in prevalence of suicide attempts across levels of sociodemographic and psychiatric disorder groups. The analyses were performed from February 8, 2017, through May 31, 2017.

Main Outcomes and Measures

Self-reported attempted suicide in the 3 years before the interview.

Results

With use of data from the 69 341 participants (42.8% men and 57.2% women; mean [SD] age, 48.1 [17.2] years), the weighted percentage of US adults making a recent suicide attempt increased from 0.62% in 2004-2005 (221 of 34 629) to 0.79% in 2012-2013 (305 of 34 712; ARD, 0.17%; 95% CI, 0.01%-0.33%; P = .04). In both surveys, most adults with recent suicide attempts were female (2004-2005, 60.17%; 2012-2013, 60.94%) and younger than 50 years (2004-2005, 84.75%; 2012-2013, 80.38%). The ARD for suicide attempts was significantly larger among adults aged 21 to 34 years (0.48%; 95% CI, 0.09% to 0.87%) than among adults 65 years and older (0.06%; 95% CI, -0.02% to 0.14%; interaction P = .04). The ARD for suicide attempts was also significantly larger among adults with no more than a high school education (0.49%; 95% CI, 0.18% to 0.80%) than among college graduates (0.03%; 95% CI, -0.17% to 0.23%; interaction P = .003); the ARD was also significantly larger among adults with antisocial personality disorder (2.16% [95% CI, 0.61% to 3.71%] vs 0.07% [95% CI, -0.09% to 0.23%]; interaction P = .01), a history of violent behavior (1.04% [95% CI, 0.35% to 1.73%] vs 0.00% [95% CI, -0.12% to 0.12%]; interaction P = .003), or a history of anxiety (1.43% [95% CI, 0.47% to 2.39%] vs 0.18% [95% CI, 0.04% to 0.32%]; interaction P = .01) or depressive (0.99% [95% CI, -0.09% to 2.07%] vs -0.08% [95% CI, -0.20% to 0.04%]; interaction P = .05) disorders than among adults without these conditions.

Conclusions and Relevance

A recent overall increase in suicide attempts among adults in the United States has disproportionately affected younger adults with less formal education and those with antisocial personality disorder, anxiety disorders, depressive disorders, and a history of violence.

Emergency Department Visits Prior to Suicide and Homicide

Abstract. Background: Emergency departments (EDs) serve a wide range of patients who present at risk of impending suicide and homicide. Aims: Two statewide surveillance systems were probabilistically linked to understand who utilizes EDs and then dies violently within 6 weeks. Method: Each identified case was matched with four randomly selected controls on sex, race, date of birth, resident zip code, and date of ED visit vs. date of death. Matched-pair odds ratios were estimated by conditional logistic regression to assess differences between cases and controls on reported diagnoses and expected payment sources. Results: Of 1,599 suicides and 569 homicides in the 3-year study period, 10.7% of decedents who died by suicide (x = 13.6 days) and 8.3% who died by homicide (x = 16.3 days) were seen in a state ED within 6 weeks prior to death. ED attendees who died by suicide were more likely to have a diagnosis of injury/ poisoning diagnosis or mental disorder and more likely to have Medicare. Those who died by homicide were more likely to have a diagnosis of injury/poisoning and less likely to have commercial insurance. Conclusion: It is essential for research to further explore risk factors for imminent suicide and homicide in ED patients who present for psychiatric conditions and general injuries.

Recent criminal offending and suicide attempts: a national sample

PURPOSE

Few studies have assessed the risk of suicide and suicidal behavior among the community-residing population with recent criminal justice involvement despite evidence of high rates of suicide in jails and prisons. This study assessed the association between recent arrest history and a suicide attempt in the previous year including multiple arrests and specific offense categories using a national representative sample of adults.

METHODS

Data were derived from 2 years of the National Survey on Drug Use and Health (2008 and 2010), a nationally representative cross-sectional survey of non-institutionalized US adults. Suicide attempts in the previous year based on self-report were assessed in relation to recent arrest history while accounting for socio-demographic factors, mental and physical health status and substance use.

RESULTS

Suicide attempts in the previous year are relatively common among those with recent arrests (2.3 %) compared to the general US population (0.4 %), with much higher prevalence among those with multiple recent arrests or charges (4.5 %). The prevalence of recent suicide attempts among those with multiple recent arrests was highest among adults aged 25-34 (5.7 %), with similar risks between men and women, and across racial and ethnic subgroups. There was no association between arrests prior to the most recent year and recent suicide attempts.

CONCLUSIONS

Suicide attempts are common among the non-institutionalized population of US adults with recent criminal justice involvement. Suicide prevention efforts in the criminal justice system should extend to clients who remain in the community both during and immediately following periods of court-processing. Future research is needed to better identify case and client characteristics indicating the highest suicide risk.

Sex differences in suicides among children and youth: the potential impact of help-seeking behaviour

OBJECTIVE

To describe sex differences in health service use among children and youth who died by suicide.

METHOD

This is a retrospective study of children and youth (aged 10 to 25 years) living in Ontario who died by suicide between April 1, 2003, and December 31, 2007. Coroner records were individually linked to outpatient physician visit, emergency department (ED) presentation, and inpatient stay administrative health care records for 724 people (192 girls and 532 boys). Only 77 (10.6%) were aged 10 to 15 years. The health services types used, number of contacts made, and the last contact were compared in boys and girls.

RESULTS

About 80% of subjects had contact with the health care system in the year before their death, typically to an outpatient physician and (or) the ED. However, not all were seen for mental health reasons. Girls had more outpatient physician and ED contact than boys and closer in time to their death. Further, girls were more likely than boys to have contact in more than one setting. Still, boys and girls did not differ in their use of an outpatient psychiatrist, some ED presentations, and in the nature and number of inpatient stays.

CONCLUSIONS

While most people were seen by an outpatient physician and (or) in the ED in the year before their death, not all received mental health care. Further research is needed to determine whether boys and girls who died by suicide differ from their peers in their health service use to guide preventive interventions.

The US National Violent Death Reporting System: domestic and international lessons for violence injury surveillance

OBJECTIVES

This article reviews and comments on the development, strengths and limitations of the US National Violent Death Reporting System (NVDRS) from a variety of domestic and international perspectives.

METHODS

The authors were provided preliminary copies of the manuscripts in this special edition and examined them to understand and put in context the elements and uses of the NVDRS so far. Their comments are based on their reading and interpretation of these papers plus their own combined experience in injury and public health surveillance from four different countries: the US, Colombia, Australia, and South Africa.

RESULTS

The NVDRS is bigger than the sum of its parts because it links existing data from multiple sources. Its adoption of modern relational database technologies offers advantages over traditional injury surveillance databases and creates new opportunities for understanding, collaboration, and partnerships. Challenges include overcoming resource limitations so that it can become a truly national system, measuring and improving its sensitivity and comparability, and the need to examine mortality in context with serious non-fatal violent events.

CONCLUSIONS

The NVDRS is an important work in progress for the US. Each country should examine its own needs, traditions, resources, and existing infrastructure when deciding what kind of violence surveillance system to develop. However, collaboration in developing common definitions and classifications provides an important foundation for international comparisons.
