Influence of contextual factors on death by suicide in rural and urban settings

Exposure to firearm injury and suicide in a rural Pennsylvania county: implications for mental and behavioral health

To evaluate the association between self-reported gun violence exposures and mental health and behavioral health indicators in a rural population. Using cross-sectional survey responses from 630 residents of a rural county in Pennsylvania, logistic regression models estimate the likelihood of residents indicating moderate or severe levels of health outcomes as a function of gun violence exposure. We control for a series of variables related to gun ownership, behavior, history with firearms and demographic characteristics. Personal firearm victimization was associated with self-reported depressive symptoms and interrupted sleep. Secondary exposure to firearm violence, particularly exposure to friends attempting or completing a suicide, was associated with higher odds of reporting severe levels (14 days or more in the past month) of depressive symptoms, anxiety, and poor sleep. For firearm suicide involving a friend or family member, the odds of reporting severe levels of all three outcomes are 3 times greater (OR 2.984, 95% CI 1.457-6.108). For each additional firearm exposure, the odds of experiencing severe levels of mental health and sleep difficulties are 1.4 times greater (OR 1.384, 95% CI 1.115-1.720). Cumulative exposures also increase the odds of reporting binge drinking and drug use. Firearm violence exposure was associated with adverse health indicators in this rural population. Approaches to counter the effects of cumulative firearm exposure and firearm suicide exposure, including reinvigorating community spaces and strengthening social supports, may help to reduce mental health burden in rural communities.

Addressing Hispanic Veterans that Live in Rural Area's Needs to Improve Suicide Prevention Efforts

Despite the alarming recent increase in suicide rates among Hispanic Veterans, suicide among this population remains relatively understudied and little is known about their needs and how to prevent suicide in this population. A mixed methods approach was utilized to conduct a needs assessment of community suicide prevention services and resources available to Hispanic Veterans living in rural areas in the Veterans Health Administration's Veterans Integrated Services Network (VISN) 8. Five themes related to the suicide prevention's needs and gaps in services were identified: (1) lack of adequate information; (2) disruptions in social support network; (3) limited or lack of access to services; (4) risky behaviors; and (5) natural disasters. Understanding the unique needs of Hispanic Veterans in rural communities and the gaps in services in these areas can help in the development of tailored suicide prevention efforts and potentially mitigate suicide disparities.

Psychiatric diagnoses, somatic disorders, and emergency dispatches among individuals who used a national suicide crisis line

Crisis line responders initiate emergency dispatches by activating 911 or other local emergency services when individuals are determined to be at imminent risk for undesired outcomes. This study examined the association of characteristics, psychiatric diagnoses, and somatic symptoms with emergency dispatches in a national sample. Veterans Crisis Line data were used to identify contacts (i.e., calls, texts, chats, emails) that were linked with medical records and had a medical encounter in the year prior to contact. Hierarchical logistic regression clustered by responders was used to identify the association among demographics, psychiatric diagnoses, and somatic disorders, and emergency dispatches. Analyses examined 247,340 contacts from 2017 to 2020, with 27,005 (10.9%) emergency dispatches. Odds of an emergency dispatch increased with each diagnosis (three diagnoses Adjusted Odds Ratio [AOR] (95% CI) = 1.88 [1.81,1.95]). Odds were highest among individuals with substance use disorders (SUD) (alcohol AOR (95% CI) = 1.85 [1.80,1.91]; drugs AOR (95% CI) = 1.63 [1.58, 1.68]), which may be a result of intoxication or overdose during contact, requiring further research. Having more psychiatric and somatic conditions was associated with greater odds of an emergency dispatch, indicating that comorbidity contributed to the need for acute care.

Veteran suicide and associated community characteristics in Oregon

Developing a public health approach to suicide prevention among United States (US) military veterans requires additional data and guidance on where, when, for whom, and what prevention resources should be deployed. This study examines veteran suicide mortality across one US state (Oregon) to identify county-level "hotspots" for veteran suicide, identify community characteristics associated with increased suicide among veterans, and examine excess spatial risk after accounting for space, time, and community characteristics. We linked Oregon mortality data with VA databases to identify veterans who had resided in Oregon and died by suicide between January 1, 2009 and December 31, 2018 (n = 1727). Community characteristic data were gathered at the county level from publicly available datasets on social determinants of health known to be associated with poor health outcomes, including suicide risk. We estimated spatial generalized linear mixed models for the full 10-year period and for each 5-year period using integrated nested Laplace approximation with county as the higher hierarchy. Smoothed standardized mortality ratios were used to identify counties with higher risk of veteran suicide. We found a small clustering of counties in the southwestern corner of Oregon that held the highest risk for veteran suicide across the ten years studied. In multivariable models, higher prevalence of unmarried persons was the only community measure significantly associated with increased veteran suicide risk. However, social contextual factors as a group, along with geographic space, explained most risk for suicide among veterans at the population level.

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).

Examination of increasing suicide rates among rural Hispanic VA patients

PURPOSE

Death by suicide is increasing more rapidly among Hispanics than non-Hispanics who use United States Department of Veterans Affairs (VA) health services, and the increase is most rapid among those living in rural areas. Our goal was to identify characteristics of rural Hispanic VA patients that contribute to this emerging disparity.

METHODS

We linked electronic medical records from the VA, personnel data from the US Department of Defense, mortality data from the US National Death Index, and data on area characteristics from the US Census Bureau to examine suicide trends among Hispanic VA patients from 2005 through 2019. After identifying the strongest predictors of suicide in the rural and urban Hispanic populations, we examined how those characteristics changed over time.

FINDINGS

Age and sex-adjusted suicide mortality rates were consistently higher for rural versus urban Hispanic patients beginning in 2012, with the most recent rolling 5-year average rates being 31.0 per 100,000 for rural compared to 20.3 per 100,000 for urban in 2019. Models to predict suicide had fair performance in the rural (accuracy = 0.62, 95% CI: 0.51, 0.73) and urban (accuracy = 0.67, 95% CI: 0.63, 0.70) groups. Mental health diagnoses were predictive of suicide among rural Hispanic patients, but there was no evidence that mental health diagnoses were increasing more rapidly in rural compared to urban patients.

CONCLUSIONS

While we confirmed that there is a higher rate of death by suicide among rural Hispanic VA patients relative to their urban counterparts, we were unable to identify clear drivers of this finding.
