Introduction: Our goal in this study was to identify stimulant abuser patients who are at specifically high risk of suicide attempt (SAT), in order to prioritize them in preventive and risk mitigation programs. Methods: We used the California State Emergency Department Database (SEDD) to obtain discharge information for 2011. The SEDD contains discharge information on all outpatient ED encounters, including uninsured patients and those covered by Medicare, Medicaid, and private insurance. We identified SAT and stimulant abuse by using the relevant International Classification of Diseases, Ninth Revision, codes. Results: The study included 10,124,598 outpatient ED visits. Stimulant abuse was observed in 0.97% of ED visits. Stimulant abuse was more common among young and middle-aged males and people with low median household income. Moreover, it was more common among Native American (1.8%) and Black (1.8%), followed by non-Hispanic White (1.1%) patients. The prevalence of SAT was 2.0% (n = 2000) for ED visits by patients with a history of stimulant abuse, and 0.3% (N = 28,606) for ED visits without a history of stimulant abuse (odds ratio 7.29, 95% confidence interval, 6.97-7.64). The SATs were directly associated with stimulant abuse, younger age (age groups >10), and non-Hispanic White and Native American race. Association of SAT with stimulant abuse was stronger in female patients. Conclusion: Stimulant abuse was the only modifiable risk factor for suicide attempt in our study. Reaching out to populations with higher prevalence of stimulant abuse (young and middle-aged individuals who are Native American or Black, with lower household income) to control the stimulant abuse problem, may reduce the risk of SAT. In this regard, people who are at higher risk of SAT due to non-modifiable risk factors (younger age, and Native American or White race) should be prioritized. Moreover, controlling stimulant abuse among women may be specifically effective in SAT prevention. [ABSTRACT FROM AUTHOR]

Introduction: Toxicologic exposures (TE) are a major preventable public health issue, with most cases due to unintentional causes. Although these cases are well documented and reported via the National Poison Data System, there is little information regarding toxicologic exposure cases in the emergency department (ED). The aim of this study was to identify demographic groups at risk for potential poisoning. Methods: This was a cross-sectional study. We used data from the California State Emergency Department Database (SEDD) 2011 for statistical analysis. Results: The study included 10,124,598 ED visits in California in 2011. The prevalence of TE was 383.4 (379.6-387.3) per 100,000 visits. Toxicologic exposures were most common among patients aged <10 years (555.4, 95% confidence interval [CI]: 544.5-566.5 per 100,000 visits). Overall, TE was more common among males. White patients showed the highest prevalence of TE compared to other racial groups (P <0.001). Subpopulation analysis showed Native American female patients ages 10-19 had a noticeably higher prevalence of TE (1,464.4, 95% CI: 802.9-2444.9 per 100,000). The prevalence of TE was higher in households of higher median income (P <0.001). Prevalence of TE among those with a history of substance use was also elevated. Conclusion: Toxicologic exposure cases in the ED are elevated in particular age and race/ethnicity groups, as well as among those with a diagnosis of substance use disorder. The strength of association between these factors and TE in the general population may be different because we examined ED visits only. Further preventive and education strategies are necessary and should target the demographic groups identified in this epidemiological study. [ABSTRACT FROM AUTHOR]

We examined whether county-level increases in continuity of mental health care (i.e., mental health visits per mental health patient) at Community Health Centers (CHCs) correspond with a decline in Emergency Department (ED) visits for suicidal ideation and self-harm (1) overall, and (2) among specific race/ethnicities across 211 counties from 10 US states, from 2006 to 2015 (sample size = 1412 county-years). We used fixed effects linear regression analyses with county-level socioeconomic covariates and year indicators. In the full sample, continuity of mental health care at CHCs varies inversely with ED visits for suicidal ideation/self-harm (coefficient: −0.04, p < 0.1). Race-specific analyses show that a one unit increase in continuity of mental health care at CHCs corresponds with a 5% decline in ED visits for suicidal ideation/self-harm among whites (p < 0.05). Expansion of mental health care services at CHCs may serve as a key point of prevention for suicidal behavior. [ABSTRACT FROM AUTHOR]

Previous literature on racism and adverse mental health largely focuses on individual-level exposures. We investigate whether and to what extent structural racism, as measured by police killings of unarmed African Americans, affect a severe and acute mental health outcome among African Americans: depression-related Emergency Department (ED) visits. We used police killings of unarmed African Americans as our exposure and depression-related ED visits (per 100,000 population) as our outcome. We examined the relation across 75 counties from five US states between 2013 and 2015 (2700 county-months). Linear fixed effect analyses controlled for time-invariant county-factors as well as the number of hospitals and arrests for violent crimes (per 100,000 population). Police killings of unarmed African Americans correspond with an 11% increase in ED visits per 100,000 population related to depression among African Americans in the concurrent month and three months following the exposure (p < 0.05). Researchers and policymakers may want to consider prevention efforts to reduce racial bias in policing and implement surveillance of fatal police encounters. These encounters, moreover, may worsen mental health and help-seeking in the ED among African Americans not directly connected to the encounter. • Police are almost 3.5 times more likely to kill Blacks than whites in the US. • We test whether these killings adversely affect mental health. • Police killings of unarmed Blacks precede increased ED visits for depression.
