Suicide prevention in a deployed military unit

Workplace interventions to prevent suicide: A scoping review

OBJECTIVES

To map organisational interventions for workplace suicide prevention, identifying the effects, mechanisms, moderators, implementation and economic costs, and how interventions are evaluated.

BACKGROUND

Suicide is a devastating event that can have a profound and lasting impact on the individuals and families affected, with the highest rates found among adults of work age. Employers have a legal and ethical responsibility to provide a safe working environment for their employees, which includes addressing the issue of suicide and promoting mental health and well-being.

METHODS

A realist perspective was taken, to identify within organisational suicide prevention interventions, what works, for whom and in what circumstances. Published and unpublished studies in six databases were searched. To extract and map data on the interventions the Effect, Mechanism, Moderator, Implementation, Economic (EMMIE) framework was used. Mechanisms were deductively analysed against Bronfenbrenner's socio-ecological model.

RESULTS

From 3187 records screened, 46 papers describing 36 interventions within the military, healthcare, the construction industry, emergency services, office workers, veterinary surgeons, the energy sector and higher education. Most mechanisms were aimed at the individual's immediate environment, with the most common being education or training on recognising signs of stress, suicidality or mental illness in oneself. Studies examined the effectiveness of interventions in terms of suicide rates, suicidality or symptoms of mental illness, and changes in perceptions, attitudes or beliefs, with most reporting positive results. Few studies reported economic costs but those that did suggested that the interventions are cost-effective.

CONCLUSIONS

It seems likely that organisational suicide prevention programmes can have a positive impact on attitudes and beliefs towards suicide as well reducing the risk of suicide. Education, to support individuals to recognise the signs and symptoms of stress, mental ill health and suicidality in both themselves and others, is likely to be an effective starting point for successful interventions.

Trends in suicide rates by race and ethnicity among members of the United States Army

Efforts were focused on identifying differences in suicide rates and time-dependent hazard rate trends, overall and within age groups, by race and ethnicity among United States Army members who returned from an index deployment (October 2007 to September 2014). This retrospective cohort study was conducted using an existing longitudinal database, the Substance Use and Psychological Injury Combat Study (SUPIC). Demographic (e.g., race and ethnicity) and military data from the Department of Defense compiled within SUPIC, as well as Department of Veterans Affairs data were linked with National Death Index records (through 2018) to identify deaths by suicide including those that occurred after military service. The cohort included 860,930 Army Service members (Active Duty, National Guard, and Reserve). Age-adjusted (using the direct standardization method) and age-specific suicide rates per 100,000 person years were calculated and rate ratios (RR) were used for comparisons. Trends were evaluated using hazard rates over time since the end of individuals' index deployments. Among those aged 18-29 at the end of their index deployment, the suicide rate for American Indian/Alaskan Native (AI/AN) individuals was 1.51 times higher (95% confidence interval [CI]: 1.03, 2.14) compared to White non-Hispanic individuals (WNH), and lower for Hispanic and Black non-Hispanic (BNH) than for WNH individuals (RR = 0.65 [95% CI: 0.55, 0.77] and RR = 0.71 [95% CI: 0.61, 0.82], respectively). However, analyses revealed increasing trends in hazard rates post-deployment (≤ 6.5 years) within groups of Hispanic and BNH individuals (Average Annual Percent Change [APC]: 12.1% [95% CI: 1.3%, 24.1%] and 11.4% [95% CI: 6.9%, 16.0%], respectively) with a smaller, increase for WNH individuals (APC: 3.1%; 95% CI: 0.1%, 6.1%). Findings highlight key subgroups at risk for post-deployment suicide (i.e., WNH, AI/AN and younger individuals), as well as heterogeneous trends overtime, with rates and trends varying within race and ethnic groups by age groups. Post-deployment suicide prevention efforts that address culturally relevant factors and social determinants of health associated with health inequities are needed.

A Qualitative Investigation of Barriers to Seeking Treatment for Suicidal Thoughts and Behaviors Among Army Soldiers with a Deployment History

This study aimed to identify barriers to treatment seeking and service utilization among previously deployed Army soldiers who recently experienced a suicidal crisis. Confidential interviews were conducted on a psychiatric inpatient unit with 12 Army soldiers with a deployment history following a suicidal crisis. Qualitative analysis focused on statements coded as "barriers to seeking help" and "explicit recommendations." Suicidal Army soldiers with a deployment history experienced different barriers to seeking help, including stigma and logistical challenges (e.g., long wait times for appointments). Negative and positive perceptions of support were reported for various resources - for example, family, crisis hotlines, chaplains, and command. Suicidal Army soldiers, interviewed in this study, experienced a number of challenges and frustrations associated with various helping resources. This study highlights the need for greater attention toward understanding these challenges and subsequently addressing them through appropriate resource allocation and additional training for those working directly with Army soldiers at risk for suicide.

A Review of Military Health Research Using a Social–Ecological Framework

Objective:

We aim to contextualize the growing body of research on the sequelae of military service in the wars in Afghanistan and Iraq. We employ a social–ecological (SE) framework for the taxonomy of military health research and classify risk as arising from the individual, family, community, and the institutional levels. We intend for this review to inform enhanced health promotion efforts in military communities.

Data Source:

Articles reviewed were extracted from Web of Science, PubMed, and Scopus.

Inclusion and Exclusion Criteria:

Research focused on somatic and psychological sequelae of combat deployment published from 2001—the year the war in Afghanistan began—through the end of 2014. We excluded studies of non-US military personnel, other systematic reviews, meta-analyses, book chapters, and theoretical papers.

Data Extraction:

We examined and summarized the aims, participants, methods, study design, SE framework tier, risk factors, and health outcomes.

Data Synthesis:

Studies were categorized according to SE tier, whether they focused on somatic, behavioral, or psychological outcomes, and by risk factor.

Results:

Of the 352 peer-reviewed papers, 84% focused on war’s sequelae on the index military personnel, and 75% focused on mental or behavioral health outcomes—mostly on post-traumatic stress disorder. We find comparatively little research focusing on the family, community, or institutional tiers.

Conclusions:

We know relatively little about how family and community respond to the return of personnel from combat deployment; how family resources affect the health of returning military personnel; and how a war’s persistence presents challenges for federal, state, and local agencies to meet military health-care needs. Such work is especially salient as US troops return home from war—particularly in communities where there are substantial military populations.

Effectiveness of suicide prevention programs for emergency and protective services employees: A systematic review and meta-analysis

BACKGROUND

This brief report summarizes the international literature on the effectiveness of suicide prevention programs for protective and emergency services employees.

METHODS

A systematic search of 11 electronic databases was undertaken until June 30, 2015. Quantitative meta-analysis was undertaken to investigate the effectiveness of these programs on suicide rates at post-intervention. Qualitative analyses were also used to identify program components that may be associated with reductions in suicide rates.

RESULTS

A total of 13 studies were included. Only six reported sufficient information on suicide rates to enable inclusion in quantitative analyses, however. On average, these programs were associated with an approximate halving in suicide rates over an average follow-up period of 5.25 years (SD = 4.2; range: 1-11) (Incidence Rate Ratio 0.45, 95%CI 0.31-0.65; five studies; I² 14.8%). Few programs integrated activities at the primary prevention level.

CONCLUSION

A greater focus on the relatively neglected area of workplace primary prevention could further improve suicide prevention effectiveness. Am. J. Ind. Med. 60:394-407, 2017. © 2017 Wiley Periodicals, Inc.

Military Service and Suicidal Thoughts and Behaviors in a National Sample of College Students

Background: As a result of the post-9/11 GI Bill, increasing numbers of veterans are enrolling in college. However, little is known regarding suicidal outcomes among this group. In prior research, college student veterans reported high rates of suicidal ideation and attempt. Nonetheless, no research has examined whether military service is associated with increased suicide risk among college students. Aims: Our primary aims were to examine whether a history of military service was related to past-year suicidal ideation, plan, and attempt among college students. On the basis of previous research with college students, we hypothesized that students with a history of military service (i.e., current or prior) would report a higher percentage of past-year suicidal ideation, plan, and attempt. Our secondary aims were to examine the associations between military service and major depression and nonsuicidal self-injury. Method: Our sample included 3,290 college students with and without a history of military service who participated in the Healthy Minds Study in 2011 and 2012. Results: Military service was not significantly associated with past-year suicidal ideation, plan, or attempt. Students without a history of military service were more likely to report nonsuicidal self-injury. There was no significant difference in screening positive for major depression. Conclusions: These findings conflict with previous research that identified student veterans as being at elevated risk.
