Background: To date, the clinical equivalence between branded and generic medications remains debate and may sometimes be a reason why psychiatrists are hesitant to prescribe generic medications. Depression is recognized to exacerbate suicide risk globally and selective serotonin reuptake inhibitors, such as fluoxetine are common treatment options. Therefore, this study aimed to explores differences in suicidal risks between users of branded and generic fluoxetine in Taiwan., Methods: This cohort study used Taiwan Longitudinal Health Insurance Database, encompassing 2 million individuals covered by National Health Insurance (NHI) program. The full cohort consisted of 32,298 fluoxetine new users. Then, 7,380 branded and 7,380 propensity score matched (PSM) generic fluoxetine new users were identified. The study further utilized Cox proportional hazards models to assess risk of 5-year suicidal ideation, suicide mortality, and all-cause mortality., Results: The study revealed that the adjusted hazard ratios (HRs) for suicidal ideation, suicide mortality and all-cause mortality in branded users were 0.766 (95% CI, 0.497 - 1.181), 0.660 (95% CI, 0.447 - 0.975), and 0.942 (95% CI, 0.849 - 1.045), respectively, when compared with matched generic fluoxetine users. Stratified and sensitivity analyses showed the lower risk of suicide mortality in specific subgroups, such as male (adjusted HRs = 0.536, 95% CI = 0.306-0.939) and young branded users (adjusted HRs = 0.549, 95% CI = 0.334-0.904)., Conclusion: This study observed trends in the prevention effects of suicide-related risks. However, only suicide mortality was statistically significant, especially in males and those aged < 40 years. These insights may assist clinicians and policymakers in decision-making., Clinical Trial Number: NA (This study is a cohort study utilizing the national health insurance database, not a clinical trial)., Competing Interests: Declarations.

Background: Suicidal behaviors, which may lead to death (suicide) or survival (suicide attempt), are influenced by various factors. Identifying the specific risk factors for suicidal behavior mortality is critical for improving prevention strategies and clinical interventions. Predicting the outcomes of suicidal behaviors can help identify individuals at higher risk of death, enabling timely and targeted interventions. This study aimed to determine the critical risk factors associated with suicidal behavior mortality and identify an effective classification model for predicting suicidal behavior outcomes., Materials and Methods: This study utilized data recorded in the suicidal behavior registry system of hospitals in Ilam Province. In the first phase, duplicate records were removed, and the data was numerically encoded via Python version 3.11; then, the data was analyzed using chi-square and Fisher's exact tests in SPSS version 22 software to identify the factors influencing suicidal behavior mortality. In the second phase, missing data were removed, and the dataset was standardized. Five binary classification algorithms were utilized, including Random Forest, Logistic Regression, and Decision Trees, with hyperparameters optimized using the area under the receiver operating characteristic curve (AUC) and F1 score metrics. These models were compared based on accuracy, recall, precision, F1 score, and AUC., Results: Among 3833 cases of suicidal behavior in various hospitals in Ilam Province, the results indicated that the method of suicidal behavior (P < 0.001), reason for suicidal behavior (P < 0.001), age group (P < 0.001), education level (P < 0.001), marital status (P = 0.004), and employment status (P = 0.042) were significantly associated with suicide. Variables such as the season of suicidal behavior, gender, father's education, and mother's education were not significantly related to suicidal behavior mortality. Furthermore, the random forest model demonstrated the highest area under the ROC curve (0.79) and the highest classification accuracy and F1 score on both the training data (0.85 and 0.2, respectively) and test data (0.86 and 0.31, respectively) for predicting suicidal behaviors outcomes among the models tested., Conclusion: This study identified key factors such as older age, lower education, divorce or widowhood, employment, physical methods, and socioeconomic issues as significant predictors of suicidal behavior outcomes. A combination of statistical models for feature selection and machine learning algorithms for prediction was used, with Random Forest showing the best performance. This approach highlights the potential of integrating statistical methods with machine learning to improve suicide risk prediction and intervention strategies., Competing Interests: Declarations.

Background: Despite pronounced increases in homelessness and mental health problems in the USA over the past decade, further exacerbated during the pandemic, and the higher prevalence of mental health conditions among individuals experiencing homelessness, no study has examined trends in self-injury-related ED visits by individuals experiencing homelessness using up-to-date nationwide data. To address this gap, we aimed to investigate the association of self-injury-related ED visits with homelessness and to examine trends in these ED visits by individuals experiencing homelessness., Methods: We conducted a retrospective secondary data analysis using a nationally representative sample of ED visits by adults aged 25-64 years in the USA from the 2016-2021 National Hospital Ambulatory Medical Care Survey. We examined whether intentional self-injury-related ED visits and hospitalisations resulting from an ED visit were associated with homeless status using survey-weighted multivariable generalised linear regression models and whether trends in such visits changed over the study period., Results: Our analysis covered 419.4 million ED visits from 2016 to 2021. Individuals experiencing homelessness constituted 1.8% (7.4 million) of ED visits. Overall, 1.8% of ED visits (7.7 million) were related to intentional self-injuries. Nearly 1 in every 10 ED visits (9.6%) by individuals experiencing homelessness were related to self-injuries, compared with 1.7% among housed counterparts (p<0.001). The adjusted incidence rate ratio for self-injury-related ED visits was 3.14 (95% CI 2.05 to 4.83) for individuals experiencing homelessness compared with housed individuals. Finally, individuals experiencing homelessness accounted for 12.0% and 11.7% of self-injury-related ED visits in 2020 and 2021, respectively (pandemic years), compared with an average of 8.4% in the previous years., Conclusion: Among adults aged 25-64 years, experiencing homelessness was significantly associated with self-injury-related ED visits, and an increase in the rate of such visits among individuals experiencing homelessness was observed during 2020 and 2021. Future studies should assess longer-term trends in these visits and explore interventions to address the societal, health and mental healthcare needs in order to improve the health outcomes of these marginalised individuals., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: Poverty is a consistent correlate of firearm-involved mortality, yet little work has considered the effects of social and economic policies on these deaths. This study examined associations of state elimination of the asset test and increases in the income limit for Supplemental Nutrition Assistance Program (SNAP) eligibility with rates of firearm-involved suicide and homicide deaths in the United States., Methods: This ecological repeated cross-sectional study used 2015-2019 data from the SNAP Policy Database and death certificate data from the National Vital Statistics System. The exposures were (1) state elimination of the asset test for SNAP eligibility and (2) state elimination of the asset test and increases in the income limit for SNAP eligibility, compared with (3) state adoption of neither policy. The outcomes were firearm-involved suicide deaths and firearm-involved homicide deaths. The research team conducted mixed-effects regressions to estimate associations., Results: State elimination of the asset test for SNAP eligibility (incidence rate ratio (IRR), 0.67; 95% CI, 0.48 to 0.91) and state adoption of both eliminating the asset test and increasing the income limit for SNAP eligibility (IRR, 0.68; 95% CI, 0.49 to 0.92) were associated with decreased rates of firearm-involved suicide deaths compared with state adoption of neither policy. There were no associations with state firearm-involved homicide rates., Conclusions: SNAP is an important social safety net programme that addresses food insecurity, and the present results suggest it may also contribute to reducing firearm-involved suicide., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objectives: To investigate the details of disaster-related deaths due to the indirect health effects of the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident following the Great East-Japan Earthquake in 2011 and serve as a source of reference in the event of similar circumstances in the future., Design: A retrospective observational study., Setting: Minamisoma City, Fukushima Prefecture, Japan, which is located 13-38 km north of the FDNPP., Participants: 520 residents of Minamisoma City, Fukushima Prefecture, who were certified as having died from disaster-related causes between September 2011 and February 2021., Results: The most common cause of death was circulatory system diseases (27.7%), followed by respiratory system diseases (25.0%) and neoplasms (15.4%). The prevalence of circulatory and respiratory diseases is higher in older people, suggesting that they are more susceptible to indirect health effects due to the environmental changes related to evacuation. Malignant neoplasms accounted for the third and leading cause of death overall and for people in their 50s, respectively, implying the potential impact of evacuation on cancer diagnosis and treatment. Suicide is the leading cause of death among younger people and can occur even long after a disaster, which shows the psychological impact of environmental changes., Conclusion: To prevent indirect disaster-related deaths in the future, it is important to consider appropriate intervention methods by age group and period since disaster occurrence. It is especially important to improve the environment of evacuation shelters and establish a healthcare system for evacuees, create a system for cancer screening and treatment during evacuation and expand long-term suicide prevention measures., Competing Interests: Competing interests: AO received personal fees from Medical Network Systems, Kyowa Kirin Company and Taiho Pharmaceutical Company outside of the submitted work.

Background: Deaths related to suicide, drug misuse, and alcohol-specific causes, known collectively as "deaths of despair" are of growing interest to researchers in England. Rates of death from these causes are highest in deprived northern communities and are closely tied to the social determinants of health and the policy decisions that have shaped them. The aim of this paper is to explore how stakeholders and community members living in Middlesbrough and South Tyneside, two Northern towns with above average rates of deaths of despair, understood the relationship between austerity policies and rates of deaths from these causes in their areas., Methods: I conducted interviews and one focus group with a total of 54 stakeholders and community members in Middlesbrough and South Tyneside. Data were analysed using the iterative categorisation technique and the findings were interpreted through thematic analysis., Results: The findings highlight four primary ways through which austerity exacerbated rates of deaths of despair in Middlesbrough and South Tyneside: reduced access to mental health services, diminished substance abuse treatment capacity, loss of youth services, and the closure of community institutions. Participants linked these cuts to rising social isolation, declining mental health, and increased substance misuse, which collectively deepened geographic inequalities in deaths of despair., Conclusions: This study underscores the urgent need for reinvestment in local services to reduce inequalities and prevent further unnecessary deaths due to drug, suicide, and alcohol-specific causes. Prioritising the restoration and enhancement of services lost to austerity is critical. Such reinvestment will not only help to alleviate some of the most immediate need but also form a foundation for addressing the wider structural inequalities that perpetuate deaths of despair., Competing Interests: Declarations Ethics approval and consent to participate This research was carried out in accordance with the Declaration of Helsinki.

Objective: West Virginia's (WV) suicide rate is 50% higher than the national average and is the highest in the Appalachian Region. Appalachia has several social factors that have contributed to greater socioeconomic deprivation, a known contributor of suicide. Given WV's high prevalence of suicide and poverty, the current study aims to examine the relationship between socioeconomic deprivation and suicide rates in WV., Methods: The Townsend Deprivation Index (TDI), Social Deprivation Index (SDI), and Social Vulnerability Index (SVI) measured socioeconomic deprivation. Negative binomial regression models assessed the relationship between socioeconomic deprivation scores, individual index items, and suicide rates. Model comparisons evaluated the indices' ability to assess suicide rates. A backward selection strategy identified additional key items for examining suicide rates., Results: There was a significant increase in suicide rates for every 10% increase in TDI (β = 0.04; p < 0.01), SDI (β = 0.03; p = 0.04), and SVI scores (β = 0.05; p < 0.01). Household overcrowding and unemployment had a positive linear relationship with suicide in TDI (β = 0.04, p = 0.02; β = 0.07, p = 0.01), SDI (β = 0.10, p = 0.02; β = 0.01, p<0.01), and the SVI (β = 0.10, p = 0.02; β = 0.03, p<0.01). The backwards selection strategy identified additional key items included by the SVI when assessing suicide., Conclusion: Greater socioeconomic deprivation, measured by the TDI, SDI, and SVI, was significantly associated with higher suicide rates. Expanding unemployment benefits and increasing the availability of affordable housing, especially in rural areas, may be useful in reducing suicide rates. Our results suggest racial and ethnic minorities and adults living with a disability may benefit from targeted suicide prevention strategies., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Caswell et al.

Depression and suicide attempts are reported to be high among medical students. It has also been reported that depression, suicide attempts, and autistic traits may be significantly related. The aim of this study was to determine the suicide probability and autistic traits of medical students with and without depression symptoms, and to examine the relationship between depression symptoms, suicide probability, and autistic traits together in these students. This cross-sectional study was conducted among 313 medical students, 206 female, and 107 male, who, according to the sociodemographic form, did not have any current psychiatric diagnosis, chronic medical or neurological disorders requiring treatment, or regular use of psychotropic medications, and who completed the forms in full. All the study participants completed a sociodemographic form, the Beck depression inventory (BDI), the suicide probability scale (SPS), and the autism spectrum quotient (ASQ).The entire study sample was divided into 2 groups: students with and without symptoms of depression, based on BDI scores. In the multivariate analysis, independent predictors of depression symptoms were examined using logistic regression analysis. The BDI total points (z = -13.99, P < .001), SPS total points (z = 10.61, P < .001), and subscale points of hopelessness (z = -9.28, P < .001), suicidal ideation (z = 8.48, P < .001), negative self-evaluation (z = -9.26, P < .001), and hostility (z = -8.10, P < .001), and the ASQ subscale points of communication (z = -5.05, P < .001), social skills (z = -6.05, P < .001), imagination (z = -3.27, P = .001), attention shifting (z = -4.35, P < .001), and ASQ total points (z = -6.64, P < .001) were significantly higher for the participants with BDI total points above the cutoff value compared to those with BDI total points below the cutoff value. Statistically significant positive correlations were found between BDI total points and SPS total points (R = 0.710, P < .001), ASQ total points (R = 0.451, P < .001), and between ASQ total points and SPS total points (R = 0.534, P < .001). The contribution of age, gender, ASQ, and SPS total points to explaining depression symptoms was evaluated using logistic regression analysis. This analysis showed that the SPS total points could be a significant predictor of depression symptoms (B = 0.112, P < .001). The findings of this study showed that the probability of suicide and the ASQ total and subscale points of communication, social skills, imagination, and attention shifting were significantly higher in medical students with symptoms of depression compared to those without depressive symptoms. Given the important relationship between symptoms of depression, suicidality, and autistic traits, it is crucial to raise awareness of these issues among medical education departments, health practitioners, medical students, and to provide the necessary guidance and clinical support for medical students to address these problems., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: Suicide is a global health concern whose rates are soaring in many low-and-middle-income countries. Public awareness campaigns have been implemented in Brazil; however, their impact is uncertain., Methods: This was an ecological study using population data from DATA-SUS, a Brazilian official notification system, selecting only deaths that were voluntarily self-inflicted (CID-10 × 60-X84). We analyzed all available data from 2000 to 2019 to assess trends before and after the national Yellow September (YS) campaign started in 2015. Differences in trends were assessed by Joinpoint Analysis (JA) and Regression Discontinuity Analysis (RDD), unadjusted and adjusted for economic factors., Results: Overall, there was a progressive increase in the rate of relative (per 100,000 inhabitants) number of suicides over time between 2000 and 2019 (57 % increase). The JA detected a change in the slope of the curve representing an acceleration in suicides starting in the year 2015. Adjusted RDD revealed the year that Yellow September started significantly change the slope of the association between time and rates of suicide (p interaction  < 0.01), and marginal analysis detected the coefficient increased from 0.07 (95%CI 0.04-0.10) to 0.27 (95%CI -0.07-0.60) suicides/year per 100,000 inhabitants., Limitations: The ecological nature of the manuscript compromises causational implications., Conclusions: We found an increase in suicidal trends in Brazil, against the global trend that coincides with the beginning of a large national awareness campaign. Although we cannot attribute causality, our results reinforce the need of further studies to better understand the role of awareness campaigns in suicide reduction interventions, including potential unintended effects., Competing Interests: Declaration of competing interest Rodolfo Furlan Damiano: Declares no conflict of Interest Loren Beiram: Declares no conflict of Interest Bianca Besteti Fernandes: Declares no conflict of Interest Maurício Scopel Hoffmann: Declares no conflict of Interest Alexander Moreira-Almeida: Declares no conflict of Interest Christian Rück: Declares no conflict of Interest Hermano Tavares: Declares no conflict of Interest André R.

Objective: This study aimed to examine acute and chronic stressors, and perceived lack social support, and their associations with depression and suicidal ideation in adolescents during the COVID-19 pandemic., Methods: Deidentified data from (N = 270,153) U.S. adolescents aged 11 to 17 who completed the Patient Health Questionnaire 9-item tool (PHQ-9) in the years 2020 and 2021 were sourced from a collection of online screening tools that are free, confidential, anonymous, and scientifically validated. In addition to depression, the survey included questions about suicidality, past/chronic stressful events, and contributors to mental health problems and sociodemographic variables. SPSS software version 28 for descriptive analyses, and Mplus version 7.31 for confirmatory factor analysis (CFA) and structural equation modeling (SEM), were respectively used., Results: Participants were predominantly female, White, and heterosexual, and exhibited a high prevalence of severe depression and a significant frequency of suicidal thoughts. Significant associations were found between past/chronic stressful events, and lack of social support, with suicidality and depression. Mental health stress due to the COVID-19 pandemic itself presented no significant associations with depression and suicidality and was weakly and negatively associated with lack of social support and past/chronic stressors., Discussion: These findings reinforce the notion that prior traumatic events can create vulnerabilities in the face of acute stressors, while social support can enhance resilience in adolescents. Factors that increase resilience, such as preventing traumatic events, reducing social stressors, and increasing social support, can serve as valuable guidelines for clinical and public health interventions., Competing Interests: Declaration of competing interest Dr. Vidal receives funding from the NIDA/AACAP Physician Scientist Training Program in Substance Abuse Research, supported by NIDA Career Development Award (K12)., (Copyright © 2024 Elsevier B.V.

Background: Suicide is a leading cause of death globally and a serious public health concern. Childhood trauma has been found to be associated with adult suicide vulnerability. Recent research has turned attention to investigating the role of attachment in the context of the childhood trauma-adult suicide relationship. The current study investigated for the first time whether attachment influences and moderates the childhood trauma-suicidality relationship, using a daily diary design, in the general population., Methods: 481 participants completed questionnaires assessing experiences of childhood trauma, attachment patterns, and history of suicidality. 243 participants continued to a daily diary phase where measures of daily stress, defeat and entrapment were completed for 7 consecutive days., Results: Higher levels of childhood trauma were associated with a history of suicide ideation and attempt and also higher levels of daily defeat, entrapment and stress during the 7 day study. Similarly, higher levels of attachment anxiety and avoidance were associated with a history of suicide ideation and attempt together with higher levels of daily defeat, entrapment and stress. However, the effects of childhood trauma on suicide history and on daily suicide vulnerability factors were not moderated by attachment anxiety or avoidance., Limitations: The measure of childhood trauma was a retrospective self-report tool that may be influenced by memory biases., Conclusions: Childhood trauma and insecure attachment are implicated in adult suicide risk. Interventions aimed at mitigating the negative effects of childhood trauma and insecure attachment should also incorporate components that target modifiable risk factors such as defeat, entrapment and stress., Competing Interests: Declaration of competing interest The authors have no conflict of interests to declare., (Copyright © 2024 The Authors.

Background: The phenomenon of suicide risk (SR) represents a psychiatric, social and environmental emergency. The acute psychiatric ward as the Italian Service for Psychiatric Diagnosis and Care (SPDC) represents the place where SR is high due to the acute and serious conditions of people hospitalized. The objective of this study was to evaluate the characteristics of subjects admitted to a SPDC over a 6-year period for SR represented by: suicidal ideation, attempted and failed suicide., Methods: With a retrospective single-center observational design, we collected hospitalizations from 01/01/2017 to 31/12/2022 in the SPDC of AUSL-Modena for SR, analyzed the modality of SR and compared the demographic and clinical variables of subjects with SR with those hospitalized for other clinical reasons in the same period. Data were statistically analyzed., Results: In the 6-year of study period, we collected 2,930 hospitalizations in the SPDC of AUSL- Modena and among them, 68% (n = 528) were carried out due to SR, which represented the second leading cause of hospitalization (18%), in particular among females (Pearson Chi2 = 17.41, p < 0.001). Individuals with SR were more frequently voluntary admitted (Pearson Chi2 = 215.41, p < 0.001) for a shorter period (7.36 ± 8.16 vs 11.66 ± 15.93, t = 6.03, t-test, p < 0.001) and less frequently repeated the hospitalization during the study period for the same reason (Pearson Chi2 = 6.0, p = 0.014). The most frequent psychiatric disorders associated with SR were depressive, personality and adjustment disorders, which represented the most common factor associated with SR (68%), followed by family/relationship problems (12%) and alcohol/substance abuse (8%). We highlighted three kinds of suicidal risk: suicidal ideation (40%), often associated with personality disorders and substance use disorders, drug ingestion (30%) concomitant with conflicting family relationships and use of violent means (30%) associated with depressive disorders (Pearson Chi2 = 42.83, p = 0.002)., Conclusions: Our study provides a real-world setting evaluation of subjects hospitalized for SR and, in accordance with literature, suggests that suicidal behavior is the product of many clinical and social factors' interaction, that occurred in a crucial moment of life in vulnerable individuals. The identification of subjects at SR represents the first step of preventive multi-professional interventions., Competing Interests: Declarations Ethics approval and consent to participate The study was approved by the Ethics Committee of the North Emilia Area Vasta (Prot. 306/2022/AOU) with subsequent amendment for extension of the period examined (Prot. 10826/2023) and authorized by the AUSL- Modena (Prot. no. 688; 27/4/2023).

Suicide, a global health concern, can be influenced by living arrangements. Hence, the objective of this systematic review was to assess the extent of the association between living alone and suicidal behaviors. We conducted a comprehensive search across eight databases for prospective studies. Hazard ratios (HR) and 95% confidence intervals were pooled using Stata software. Nine large-scale prospective studies with 3,663,205 participants proved eligible. The results of the meta-analysis showed that the pooled prevalence of living alone was 32%. Living alone was associated with suicide attempts and suicide death even after adjusting for all potential confounding factors (AHR = 1.45, 95% CI : 1.13-1.77; AHR = 1.27, 95% CI : 1.06-1.48). Compared to people who live with others, living alone increases the risk of suicide behaviors. Given the anticipated global rise in suicide rates and the growing prevalence of living alone, it is recommended to explore this issue on a broader scale.

Background: In Japan, few studies have examined suicide risk for 5-year relative survival rates for cancer sites. Since 5-year relative survival rates differ by sex, we aim to examine suicide risk for patients with cancer separately for men and women., Methods: We estimated the risk of suicide among patients with cancer by sex in Japan compared to the general population, using standardized mortality ratios (SMRs). Patients with cancer diagnosed between January 1, 1985-December 31, 2013 and registered in the Osaka Cancer Registry were followed for up to 10 years. The outcome was suicide death. In addition, cancer sites were classified into three prognosis groups based on 5-year relative survival rates: good (>70%), moderate (40-70%), poor (<40%)., Results: Among 623,995 patients with cancer observed for 2,349,432 person-years, 1,210 patients died by suicide (867 men and 343 women). The SMRs were almost equal for men (1.66; 95% confidence interval [CI], 1.55-1.77) and women (1.65; 95% CI, 1.48-1.83). SMRs for cancer prognosis groups were 1.01 (95% CI, 0.84-1.22) for men and 1.47 (95% CI, 1.24-1.73) for women in the good group, 1.53 (95% CI, 1.39-1.68) for men and 1.74 (95% CI, 1.47-2.05) for women in the moderate group, and 2.54 (95% CI, 2.27-2.85) for men and 1.87 (95% CI, 1.43-2.46) for women in the poor group., Conclusion: In this population, both sexes had higher suicide risk with poor prognosis, but the difference in SMRs between the good and poor groups was smaller for women than men.

Objective: To evaluate the relationship between a predelivery history of concussion and risk of severe maternal mental illness., Methods: We conducted a population based cohort study of birthing people with a singleton livebirth accrued between 2007 and 2017 with follow-up to 2021 in Ontario, Canada. The primary outcome was severe maternal mental illness, defined as a psychiatric emergency department visit, psychiatric hospital admission, or self-harm or suicide in the 14 years after delivery. Cox proportional hazards regression generated adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) comparing those with a history of a health care encounter for concussion between database inception and the index delivery date to those without a recorded health care encounter for concussion, adjusted for maternal age, parity, neighborhood income quintile, rural residence, immigration status, chronic conditions, history of interpersonal violence, and history of mental illness. Results were also stratified by history of mental illness., Results: There were n = 18,064 birthing people with a history of concussion and n = 736,689 without a history of concussion. Those with a history of concussion had an increased risk of severe maternal mental illness compared to those without this history (14.7 vs 7.9 per 1,000 person-years; aHR 1.25, 95% CI, 1.20-1.31). After stratification by predelivery history of mental illness, the association was strongest in individuals with no mental illness history (aHR 1.33, 95% CI, 1.23-1.44)., Conclusion: These findings indicate the need for early identification and screening of birthing people with a history of concussion, as well as ongoing long-term supports using trauma informed approaches to prevent adverse psychiatric outcomes., (© Copyright 2024 Physicians Postgraduate Press, Inc.)

Importance: The rising suicide rates in the US emphasize the need for effective prevention. While telehealth has transformed access to mental health care, the impact of telehealth on suicide outcomes is unknown., Objective: To evaluate the association of virtual mental health services with individual-level suicide-related events (SREs)., Design, Setting, and Participants: This retrospective cohort study using broadband access as an instrumental variable assessed a national sample of Veterans Health Administration patients who received mental health care between March 1, 2020, and December 31, 2021. Participants were recently separated (ie, discharged or released from active duty) veterans who completed their active duty service between March 1, 2019, and December 31, 2020, and who received at least 2 outpatient or inpatient diagnoses related to major depressive disorder, substance use disorder, or posttraumatic stress disorder within the year before their most recent separation date. Data were analyzed May 1 to October 31, 2023., Exposure: Percentage of a patient's total mental health visits that were conducted virtually by psychiatrists, psychologists, or social workers within a calendar month., Main Outcomes and Measures: Binary measure indicating whether the patient had experienced an SRE (defined as a nonfatal suicide attempt, intentional self-harm, or suicide death) in a specific month and year as evaluated an instrumental variable probit model., Results: The sample included 66 387 data points from 16 236 unique recently separated veterans. Among these entries, 44 766 were for male veterans (67.4%), the mean (SD) age across the sample was 32.9 (8.9) years, and the sample was representative of the US veteran population. There were 929 SREs (1.4%). Virtual mental health visits comprised a mean (SD) of 44.6% (46.1%) of all mental health visits. In instrumental variable probit analyses accounting for factors simultaneously associated with use of virtual mental health care and SRE risk, a 1% increase in the probability of virtual mental health visits was associated with a 2.5% decrease in SREs., Conclusions and Relevance: Findings from this cohort study using a retrospective quasi-experimental design found that an increase in virtual mental health visits relative to total visits was associated with a statistically significant decrease in SREs, suggesting that providing virtual mental health services may reduce suicide-related outcomes.

Aims: The aim of this 4-year follow-up study was to examine the predictive effects of demographics, three types of sexual stigma, three types of self-identity confusion, anxiety, depression, family support and problematic Internet use before the coronavirus disease 2019 (COVID-19) pandemic on new-onset suicide risk and persistent suicide risk in young adult lesbian, gay and bisexual individuals who experienced the COVID-19 pandemic in Taiwan., Methods: Baseline data were collected from 1,000 lesbian, gay and bisexual individuals in 2018 and 2019. Outcome data on suicide risk were collected again in 2023. The suicide module of the Mini International Neuropsychiatric Interview was used to assess suicide risk in terms of thoughts of death, desire to self-harm, thoughts of suicide, plans for suicide and suicide attempts in the preceding month at the initial and follow-up assessments. Baseline three types of sexual stigma, self-identity disturbance, depression, anxiety and problematic Internet use were used to examine their prediction of new-onset suicide risk and persistent suicide risk at follow-up., Results: In total, 673 individuals participated in the follow-up survey. Notably, 16.5% of the participants who had no suicide risk at baseline had new-onset suicide risk at follow-up; 46.4% of the participants who had suicide risk at baseline also had suicide risk at follow-up. Participants who were transgender ( p  = .003), who perceived greater levels of microaggression ( p  < .001), and who had greater levels of problematic Internet use at baseline ( p  = .024) were more likely to have new-onset suicide risk at follow-up. Participants who had greater levels of self-identity confusion were more likely to have persistent suicide risk at follow-up ( p  = .023)., Conclusion: Intervention strategies for reducing suicide risk in lesbian, gay and bisexual individuals should be developed with consideration of the predictors identified in this study.

Background: External causes of death, such as accidents, substance use, and suicide, contribute substantially to mortality during adolescence and early adulthood and show marked sex differences. Individuals born preterm are at increased risk of mental disorders, and impaired cognitive and executive functions, potentially increasing their vulnerability to death from external causes. We investigated sex-specific associations between gestational age at birth and mortality from external causes during late adolescence and early adulthood., Methods: Individual level data from national health registries in Denmark (1978-2001), Finland (1987-2003), Norway (1967-2002), and Sweden (1974-2001) were linked to form nationwide cohorts. In total, 6,924,697 participants were followed from age 15 years to a maximum of 50 years in 2016-2018. Gestational age was categorized as "very/moderately preterm" (23-33 weeks), "late preterm" (34-36 weeks), "early term" (37-38 weeks), "full term" (39-41 weeks), and "post term" (42-44 weeks). Outcomes were mortality from external causes overall and from the largest subgroups transport accidents, suicide, and drugs or alcohol. We estimated sex-specific hazard ratios (HRs), with full term as the reference, and pooled each country's estimates in meta-analyses., Results: Across gestational ages mortality was higher for males than females. Individuals born very/moderately preterm had higher mortality from external causes, with HRs 1.11 (95% confidence interval [CI] 0.99-1.24) for males and 1.55 (95% CI 1.28-1.88) for females. Corresponding estimates for late preterm born were 1.11 (95% CI 1.04-1.18) and 1.15 (95% CI 1.02-1.29), respectively. Those born very/moderately preterm had higher mortality from transport accidents, but precision was low. For females, suicide mortality was higher following very/moderately preterm birth (HR 1.76, 95% CI 1.34-2.32), but not for males. Mortality from drugs or alcohol was higher in very/moderately and late preterm born males (HRs 1.23 [95% CI 0.99-1.53] and 1.29 [95% CI 1.16-1.45], respectively) and females (HRs 1.53 [95% CI 0.97-2.41] and 1.35 [95% CI 1.07-1.71], respectively, with some heterogeneity across countries)., Conclusions: Mortality from external causes overall was higher in preterm than full term born among both males and females. A clear sex difference was seen for suicide, where preterm birth was a risk factor in females, but not in males., (© 2024. The Author(s).)

Suicide remains a leading cause of death in the United States, and recent data suggest suicide deaths involving opioids are increasing. Given unprecedented increases in drug-poisoning deaths, suicidality, and suicide deaths in recent years, an updated examination of the trends in suicide deaths involving opioids is warranted. In this descriptive epidemiologic analysis, we leverage final and provisional mortality data from the US Centers for Disease Control and Prevention's WONDER database to examine trends in suicide deaths involving opioid poisoning from 1999 to 2021 by biological sex. Results reveal complex changes over time: the number and age-adjusted rate of suicide deaths involving opioid poisoning among male and female residents tended to track together, and both increased through 2010, but then diverged, with the number and rate of suicide deaths involving opioid poisoning among female residents outpacing that of male residents. However, the number and rate of suicide deaths involving opioid poisoning among male residents then began to stabilize, while that of female residents declined, closing the sex-based gap. Across all years of data, the proportion of suicide deaths that involved opioid poisoning was consistently higher among female decedents (5.8%-11.0%) compared with male decedents (1.4%-2.8%). Findings have implications for improved suicide prevention and harm reduction efforts. This article is part of a Special Collection on Mental Health., (© The Author(s) 2024.

Abstract: Suicide is now considered a public health problem as millions of people die this way every year. Although there are numerous conditions that can lead to the occurrence of this event, it has been possible to observe that it occurs more frequently in particular categories of individuals, such as cancer patients. Studies conducted on this type of population over long periods have also made it possible to evaluate a variation in the incidence of suicidal events in relation to the type of tumor, probably due to the perception of a different severity of the pathology or to the idea of an inevitable worsening of the quality of life. This is why the incidence of suicide is higher in the case of prostate, lung, and colorectal cancer, being less common in other types. In recent years, the improvement of both curative and palliative therapies and therefore of life expectancy have led to a change in the incidence rate of these events, in support of what was said previou-sly. Today, suicide is considered a public health problem: since it is known that the population suffering from cancer is at greater risk, it is necessary to improve prevention, trying to intercept the most fragile subjects early and thus avoid the occurrence of these events.

The number of alcohol-related deaths in Lithuania has fallen by almost one-third in the last decade; however, the number of deaths has been on the rise since 2019. Data on the postmortem investigation of victims between 2018 and 2022 were obtained from the Lithuanian State Forensic Medicine Service database. This study analyzed data from 1200 autopsies. The deceased victims were categorized based on their cause of death and blood alcohol concentration (sober, legally intoxicated, mild, medium, or heavy). The causes of death were diseases (54.17 %, n = 650), suicides (12.08 %, n = 145), homicides (2.5 %, n = 30), and accidents (31.25 %, n = 375). Toxicological tests for alcohol were performed in all cases. Alcohol levels in the blood and urine were measured using gas chromatography. A significant correlation was observed between blood alcohol concentration and age (r = -0.13, p = 0.007). A statistically significant difference was observed in the proportions of men and women who were intoxicated. Among the causes of death, the group of individuals who died because of accidents exhibited the highest average blood alcohol concentration. Alcohol intoxication is undoubtedly a contributing factor to fatalities resulting from accidents and homicides. These findings assist in determining the intoxication level of victims and in assessing any potential links that may contribute to or predispose victims to lethal outcomes in cases of disease, suicide, homicide, or accident., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest regarding the publication of this article., (Copyright © 2024.

Objectives: Sexual- and gender-diverse youth face unique stressors that negatively impact their health. The objective of this study was to use National Fatality Review-Case Reporting System data to epidemiologically describe fatalities among identified sexual- and gender-diverse youth to inform future prevention efforts., Methods: We used 2015 to 2020 data from the National Fatality Review-Case Reporting System to identify deaths among sexual- and gender-diverse youth and compare their characteristics to a matched sample of youth from these same data who were not known to be sexual- and gender-diverse. Demographic, injury, death, history, and life stressor characteristics were analyzed using descriptive statistics., Results: During the study period, 176 fatalities were identified among sexual- and gender-diverse youth. Decedents' mean age was 15.3 years. A greater proportion of deaths was attributed to suicide among sexual- and gender-diverse youth (81%) compared with nonsexual- and gender-diverse youth (54%). Receiving prior (69%) and/or current (49%) mental health services was more common among sexual- and gender-diverse youth, compared with nonsexual- and gender-diverse youth (50% and 31%, respectively). Sexual- and gender-diverse youth were significantly more likely to experience problems in school or be victims of bullying, compared with nonsexual- and gender-diverse youth (63% versus 47% and 28% versus 15%, respectively)., Conclusions: Suicide was the most common manner of death for sexual- and gender-diverse youth, despite many decedents receiving current or prior mental health services. These findings indicate the need to improve and diversify interventions to prevent these deaths., Competing Interests: CONFLICT OF INTEREST DISCLOSURES: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2024 by the American Academy of Pediatrics.)

Background: Limited research exists on suicide among children aged 5 to 9 years. The objective of this study was to examine characteristics of suicide in children younger than 10 years., Methods: Data are from the National Fatality Review-Case Reporting System (NFR-CRS) for years 2006 through 2021 for children aged 6 to 9 years who died by suicide. No suicide deaths were reported in NFR-CRS for children aged ≤ 5 years. Descriptive analyses by demographics and circumstances were conducted. A thematic analysis of prevention recommendations made by child death review teams was performed., Results: From 2006 to 2021, NFR-CRS identified 78 suicide decedents aged 6 to 9 years. The largest share were aged 9 years (72%), male (74%), non-Hispanic Black (42%), and died by hanging (86%) at home (91%). School-related problems (39%), history of child maltreatment (36%), history of mental health services (30%), argument with parents (23%), and familial discord (19%) were common circumstances. Key suicide prevention themes included education for caregivers and school staff, improved behavioral health services, and implementation of school policies and programs., Conclusions: Results provide a more complete picture of suicide among younger children, improving understanding of their unique characteristics. It is recommended that program planners consider both age-appropriateness and the impacts of social (eg, racism) and structural inequities in their approaches to prevention, encompassing both community and school-based strategies. For pediatricians, results emphasize the importance of lethal means counseling, safety planning, and educating parents and caregivers on the distinct warning signs of suicide for younger children., Competing Interests: CONFLICT OF INTEREST DISCLOSURES: The authors have indicated they have no conflicts of interest relevant to this article to disclose., (Copyright © 2024 by the American Academy of Pediatrics.)

Aims : While there is substantial literature on gender and research productivity, bearing mixed results, no study is available for suicidology. The present investigation fills this gap and focuses on an influential elite. Methods : Data are taken from the Web of Science (WoS). They refer to the most prolific suicidologists ( N = 116) with 70 or more works on the subject of suicide cited in WoS. Measures of research productivity include the number of works on suicide, citations to these works, and the h-index. The link between gender and the measures of research productivity is adjusted for years of experience, membership in a local research cluster, and region of the world. Results : Adjusting for the other predictors, males had more publications than females. However, gender did not predict either measure of quality of research (citations, h-index). Years of experience, as well as membership in a research cluster, predicted research productivity in most analyses. Region was unrelated to research productivity. Limitations : Further work on productivity might assess additional potential predictors including marital status, grant funding, and presence of young children. Conclusion : There is no significant difference between the genders in research quality. Similar results have been noted in previous work on prolific scientists.

Suicide is a leading cause of death. Suicide rates are particularly elevated among Department of Veterans Affairs (VA) patients. While VA has made impactful suicide prevention advances, efforts primarily target high-risk patients with documented suicide risk. This high-risk population accounts for less than 10% of VA patient suicide deaths. We previously evaluated epidemiological patterns among VA patients that had lower classified suicide risk and derived moderate- and low-risk groupings. Expanding upon VA's leading suicide prediction model, this study uses national VA data to refine high-, moderate-, and low-risk specific suicide prediction methods. We selected all VA patients who died by suicide in 2017 or 2018 (n = 4584), matching each case with five controls who remained alive during treatment year and shared suicide risk percentiles. We extracted all sample unstructured electronic health record notes, analyzed them using natural language processing, and applied machine-learning classification algorithms to develop risk-tier-specific predictive models. We calculated area under the curve (AUC) and suicide risk concentration to evaluate predictive accuracy and analyzed derived words. RESULTS: Our high-risk model (AUC = 0.621 (95% CI: 0.55-0.68)), moderate-risk (AUC = 0.669 (95% CI: 0.64-0.71)), and low-risk (AUC = 0.673 (95% CI: 0.63-0.72)) models offered significant predictive accuracy over VA's leading suicide prediction algorithm. Derived words varied considerably, the high-risk model including chronic condition service words, moderate-risk model including outpatient care, and low-risk model including acute condition care. Study suggests benefit of leveraging unstructured electronic health records and expands prediction resources for non-high-risk suicide decedents, an historically underserved population., Competing Interests: Declaration of competing interest The authors have no conflicts of interests.

Objective: With increased utilization of virtual care in mental health, examining its appropriateness in various clinical scenarios is warranted. This study aimed to compare the risk of adverse psychiatric outcomes following virtual versus in-person mental health follow-up care after a psychiatric emergency department (ED) visit., Methods: Using population-based health administrative data in Ontario (2021), we identified 28,232 adults discharged from a psychiatric ED visit who had a follow-up mental health visit within 14 days postdischarge. We compared those whose first follow-up visit was virtual (telephone or video) versus in-person on their risk for experiencing either a repeat psychiatric ED visit, psychiatric hospitalization, intentional self-injury, or suicide in the 15-90 days post-ED visit. Cox proportional hazard models generated adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs), adjusted for age, income quintile, psychiatric hospitalization, and intentional self-injury in the 2 years prior to ED visit. We stratified by sex and diagnosis at index ED visits based on the International Classification of Diseases and Related Health Problems, 10th Revision, Canada (ICD-10-CA) coding., Results: About 65% ( n  = 18,354) of first follow-up visits were virtual, while 35% ( n  = 9,878) were in-person. About 13.9% and 14.6% of the virtual and in-person groups, respectively, experienced the composite outcome, corresponding to incidence rates of 60.9 versus 74.2 per 1000 person-years (aHR 0.95, 95% CI 0.89 to 1.01). Results were similar for individual elements of the composite outcome, when stratifying by sex and index psychiatric diagnosis, when varying exposure (7 days) and outcome periods (60 and 30 days), and comparing "only" virtual versus "any" in-person follow-up during the 14-day follow-up., Conclusions and Relevance: These results support virtual care as a modality to increase access to follow-up after an acute care psychiatric encounter across a wide range of diagnoses. Prospective trials to discern whether this is due to the comparable efficacy of virtual and in-person care, or due solely to appropriate patient selection may be warranted., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Importance: Changes in suicide rates after a nationwide trauma may be different from changes in psychiatric symptoms or general distress after such events. However, very few studies have examined short-term suicide-related reactions after such an event., Objective: To evaluate the short-term outcome of the events in Israel on October 7, 2023, a large-scale terror attack and unfolding war, on changes in suicidality as reflected in percentages of suicide-related calls in relation to all calls to a national mental health first aid helpline, the Israeli Association for Emotional First Aid (ERAN)., Design, Setting and Participants: The data included all interactions via the various ERAN helpline services between January 1, 2022, and December 31, 2023., Exposures: The October 7, 2023, terror attack on Israel., Mean Outcomes and Measures: Changes in the numbers of overall calls and suicide-related calls to the ERAN helpline using an interrupted time-series analysis., Results: A total of 602 323 calls were received by the ERAN helpline. The number of calls reflecting psychological distress in the 3 months before October 7, 2023, was 67 555 compared with 89 445 calls in the 3 months after. Analysis indicated that overall calls increased significantly on October 7 (β = 2089.16; 95% CI, 1918.97-2259.35). In addition, the daily trajectory of all calls changed significantly after October 7 (β = -22.77; 95% CI, -33.37 to -12.16), such that there was a decrease in the number of calls per day (β = -11.34; SE = 1.213; t = -9.35; P < .001). The number of suicide-related calls in the 3 months before October 7 was 1887, whereas 1663 suicide-related calls were registered in the 3 months after. Analysis showed that there were no changes in the daily number of suicide-related calls from before October 7 (β = -0.001; 95% CI, -0.005 to 0.03) or on October 7 (β = -0.22; 95% CI, -3.69 to 3.25). Therefore, the percentage of suicide-related calls decreased significantly on October 7 (β = -1.42; 95% CI, -1.92 to -0.92) and gradually increased in the following period (β = 0.016; 95% CI, 0.006-0.026)., Conclusions and Relevance: The findings of this cohort study suggest that although short-term emotional distress increased after national trauma, the percentage of suicide-related calls decreased. These results support previous studies suggesting that suicidality is not one of the immediate reactions to such traumas.

Objectives: In recent years, there has been an increase in suicide rates in Brazil. From 2015 to 2019, a 34% increase in self-inflicted deaths was observed. The aim of this study was to analyse population data to determine whether some subgroups of the population, specifically the elderly population with Alzheimer's disease, are at a greater risk of suicide., Study Design: An analysis of population data was carried out., Methods: Population data from the state of São Paulo, Brazil, were obtained from two platforms: the Brazilian Institute of Geography and Statistics (IBGE); and the Brazilian Ministry of Health (DataSUS). Data were measured and compared in 2010 and 2022 using the two most recent censuses., Results: Between 2010 and 2022, the number of registered deaths of patients with Alzheimer's increased by 21.93%. In addition, there was a 100.37% increase in suicides among the elderly population compared to a 37.78% increase in the general population., Conclusions: In recent years, there has been a notable increase in both suicides among the elderly and mortality rates attributed to Alzheimer's disease within São Paulo state, Brazil. However, it is not possible to conclude that the increase in suicide among the elderly is directly linked to Alzheimer's disease. To determine a correlation between suicide and Alzheimer's disease, further studies are required., Competing Interests: Competing interests The authors declare no conflicts of interest., (Copyright © 2024 The Royal Society for Public Health.

Objective: Literature on temporal patterns of suicidality among youths during the COVID-19 pandemic is growing. The present work proposes a Bayesian approach to assess temporal patterns of suicide-related behaviours among inpatient adolescents during the COVID-19 pandemic., Methodology: Data referred to the first hospital discharge record with ICD9-CM codes related to suicide-related behaviour and/or suicidal ideation among adolescents aged 13-19 between 1 January 2017 and 31 March 2021 were collected in the Piedmont region, Italy (n = 334; median age: 15 years, IQR: 14-16; 80% girls). A Poisson Bayesian regression model performed on pre-COVID-19 data (2017-2020), adjusted by seasonality and stratified by sex, was adopted to provide the probability that the predicted counts exceed the observed ones in each pandemic year quarter., Results: A declining trend of suicidality was observed in April-June 2020 among both sex groups. Among females, an increasing pattern of suicidality was registered in early 2021 (January-March) compared to the pre-pandemic period., Conclusion: The present findings contributed to a growing literature on the COVID-19 pandemic's impact on adolescents' suicide-related behaviours from a gender perspective and encouraged wider adoption of Bayesian approaches as valuable tools to explore rare events and deeply enlighten open public health issues., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

Importance: Concerns have been raised regarding a link between use of glucagon-like peptide-1 (GLP-1) receptor agonists and increased risk of suicidality and self-harm., Objective: To assess the association between use of GLP-1 receptor agonists and the risk of suicide death in routine clinical practice., Design, Setting, and Participants: This active-comparator new-user cohort study used nationwide register data from Sweden and Denmark from 2013 to 2021. Adults 18 to 84 years old who initiated treatment with GLP-1 receptor agonists or the comparator sodium-glucose cotransporter-2 (SGLT2) inhibitors were included. Data were analyzed from March to June 2024., Exposure: Initiation of treatment with a GLP-1 receptor agonist or SGLT2 inhibitor., Main Outcomes and Measures: The primary outcome was suicide death recorded in the cause of death registers. Secondary outcomes were the composite of suicide death and nonfatal self-harm and the composite of incident depression and anxiety-related disorders. Using propensity score weighting, hazard ratios (HRs) with 95% CIs were calculated separately in the 2 countries and pooled in a meta-analysis., Results: In total, 124 517 adults initiated a GLP-1 receptor agonist and 174 036 initiated an SGLT2 inhibitor; among GLP-1 receptor agonist users, the mean (SD) age was 60 (13) years, and 45% were women. During a mean (SD) follow-up of 2.5 (1.7) years, 77 suicide deaths occurred among users of GLP-1 receptor agonists and 71 suicide deaths occurred among users of SGLT2 inhibitors: weighted incidences were 0.23 vs 0.18 events per 1000 person-years (HR, 1.25; 95% CI, 0.83-1.88), with an absolute difference of 0.05 (95% CI, -0.03 to 0.16) events per 1000 person-years. The HR was 0.83 (95% CI, 0.70-0.97) for suicide death and nonfatal self-harm, and the HR was 1.01 (95% CI, 0.97-1.06) for incident depression and anxiety-related disorders., Conclusions and Relevance: This cohort study, including mostly patients with type 2 diabetes, does not show an association between use of GLP-1 receptor agonists and an increased risk of suicide death, self-harm, or incident depression and anxiety-related disorders. Suicide death among GLP-1 receptor agonist users was rare, and the upper limit of the confidence interval was compatible with an absolute risk increase of no more than 0.16 events per 1000 person-years.

We aimed to quantify the risk, mortality, and burden of suicide among autistic persons. We searched PubMed, Embase, and PsycINFO on 5 th April 2023 for sources reporting the relative risk (RR) of suicide or suicide attempt among autistic persons (PROSPERO registration: CRD42021265313). Autism spectrum prevalence and suicide mortality and years of life lost (YLLs), were sourced from the Global Burden of Disease Study 2021. RRs pooled via meta-regression and health metrics estimates were used to estimate the excess suicide mortality and YLLs among autistic persons. We sourced 983 unique studies of which ten studies met inclusion criteria, consisting of 10.4 million persons. The pooled RR for suicide for autistic persons was 2·85 (95% UI: 2·05-4·03), which was significantly higher for autistic females than autistic males. No evidence of publication bias was detected via inspection of funnel plot and Egger's test. Globally, we estimated 13 400 excess suicide deaths among autistic persons in 2021, equating to 1·8% of all suicide deaths and 621 000 excess YLLs. Studies were limited in number and geographical coverage. Effective suicide prevention strategies for autistic persons may substantially reduce the fatal burden of suicides globally and reduce the health burden experienced within this population., Competing Interests: Declaration of competing interest All authors declare that they have no conflict of interests, (Copyright © 2024.

Objectives: The aim of this study was to explore sex-specific disparities in rates of deaths of despair across 183 countries from 2000 to 2019., Study Design: Secondary analysis of cross-sectional population-level data., Methods: Data were obtained from the World Health Organization Health Inequality Data Repository. We analysed data on mortality due to alcohol, drug-use disorders, and self-harm (as a proxy for suicide). We calculated the average rate of deaths of despair by year and sex, trends in these rates, and cause-specific mortality trends. We then fitted mixed-effect generalised linear models to compare mortality rates by sex and country., Results: Analyses revealed significant disparities by sex, with a 3.3-fold higher rate among men than among women globally (95% confidence interval: 3.1-3.5, P < 0.001). There was a significant decline in deaths of despair globally and among both sexes during the assessed period (5% per 5 years). Lesotho, Belarus, the US, the Russian Federation, Guyana, and Slovenia ranked among the top 10 countries out of 183 with the highest mortality rates for both sexes. Canada, the Republic of Korea, Belgium, and Finland were countries with the highest mortality rates among women, whereas Ukraine, Lithuania, Mongolia, and Eswatini have the highest rates among men. In the US, 5-year mortality rates increased by 35% for women and 21% for men: drug-use mortality showed a significant increase over time, whereas suicide rates decreased for both sexes in the given country. Additionally, mortality rates from alcohol use decreased among women., Conclusions: This global analysis shed light on health disparities by sex in deaths of despair, especially concerning trends in the US. It identified countries and groups in need of targeted mental health and substance-use programs. Moreover, the disparities by sex revealed in this analysis suggest that mental health and substance-use interventions and programs may need to be more attentive to sex and/or gender, such as inequitable social norms and restrictive forms of masculinities, which have been shown to be contributing factors to deaths of despair., (Copyright © 2024 The Author(s).

Background: Physician burnout and poor mental health are highly prevalent issues within the surgical community. Authenticity, defined as the degree to which individuals align their actions with their true selves, has been identified as a potential factor facilitating positive mental health. This study explores the impact of authenticity on burnout, depression, and suicide among surgeons., Study Design: Members of the department of surgery at a large academic medical center were sent an anonymous survey between April and May 2023. The survey evaluated authenticity using Authenticity Scale, depression using Patient Health Questionnaire, burnout using Copenhagen Burnout Inventory, and suicidality using Ask-Suicide Screening Questions (ASQ) tool., Results: Of the 170 surgeons, 94 (55.3%) completed the survey. Higher Authentic Living Scores correlated with reduced burnout (r = -0.21, p = 0.047) and depression (r = -0.37, p = 0.0002). Conversely, higher Accepting External Influence (AEI) scores were associated with increased depression (r = 0.23, p = 0.023), and higher Authenticity Self-Alienation (ASA) scores were associated with increased burnout (r = 0.43, p < 0.0001) and depression (r = 0.48, p < 0.0001). Although authenticity domain scores were not significantly associated with ASQ, specific AEI and ASA questions indicated an elevated odds ratio (p = 0.029 and p = 0.010, respectively) of a positive ASQ. Authentic Living Score increased with advancement in professional rank (p = 0.007), whereas AEI (p = 0.0001), ASA (p = 0.003), depression (p = 0.014), and ASQ (p = 0.02) decreased., Conclusions: In this study, higher authenticity was associated with a lower likelihood of burnout and depression among surgeons. This study contributes valuable insights into the development of targeted intervention and support mechanisms aimed at promoting authenticity and mental health within the surgical profession., (Copyright © 2024 by the American College of Surgeons.

Objectives: To assess all-cause mortality and suicides after pediatric traumatic brain injury (pTBI)., Study Design: We conducted population-based historical cohort study using three nationwide registers from 1998 to 2018 in Finland. All patients that were the age of 0-17 at the time of the pTBI were included. The reference group consisted of children with ankle or wrist fractures. We used Kaplan-Meier and restricted mean survival time (RMST) analysis with 95% confidence intervals (CI) to compare all-cause mortality and suicides between groups., Results: After 20 years of follow-up, there were 479 deaths in the pTBI group (0.67% of 71,963) and 306 deaths in the reference group (0.47% of 64,848). In the pTBI group, 28.6% of the deaths occurred after the first follow-up year, compared to 2.6% in the reference group. In all-cause mortality, survival time was slightly less in the pTBI group with age and gender adjustment throughout the follow-up period [20-year RMST ratio: 0.995; CI (0.994-0.996)]. The leading manners of death were suicides (pTBI group = 28.4%; reference group = 45.5%) and traffic collisions (pTBI group = 37.4%; reference group = 20.8%). Age and gender-adjusted survival time was slightly less for those with suicide as a manner of death in the pTBI group [10-year RMST ratio: 0.999; CI (0.999-0.999); 20-year RMST ratio: 0.999; CI (0.998-0.999)]., Conclusions: Children and adolescents who sustained a TBI have slightly lower long-term survival time for all-cause mortality, most of which occurs during the first year following injury. There is no clinically meaningful difference in deaths by suicide between the two injury groups., (Copyright © 2024 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Purpose: Previous studies have reported that levels of rurality and deprivation are factors associated with suicide risk. Reports on the association between rurality, deprivation and suicide incidence during the COVID-19 pandemic are scarce. The study aims to investigate how suicide rates evolved in areas with different levels of rurality and deprivation among Japanese adults aged 20 years or older between 2009 and 2022., Methods: This study used population density in 2020 as an indicator of rurality and per capita prefectural income in 2019 as a proxy for deprivation in Japan's 47 prefectures. Joinpoint regression analysis was performed to analyze secular trends in suicide rates by rurality and deprivation., Results: Suicide rates for both men and women at different levels of rurality and deprivation remained roughly parallel during the research period. Suicide rates for men and women at all levels of rurality and deprivation were on a downward trend until around 2019, just before the onset of the pandemic. Following this, suicide rates in women showed a clear upward trend, while the trend in suicide rates for men also changed around 2019, with a slightly increasing or flat trend thereafter. Changes in suicide rates were greater among women and those aged 20-59 years., Conclusions: In Japan, time trends in suicide rates for both men and women have changed before and after the pandemic, but levels of rurality and deprivation across the 47 prefectures do not appear to have contributed much to these changes., (© 2024.

Objectives: Indigenous people experience poorer mental health compared to the general population. Socioeconomic gaps partly explain these disparities. However, there is variability between populations and French overseas territories are understudied. This study examines the prevalence of mental health problems among Indigenous people in New Caledonia and French Polynesia, describing and comparing it with that of their counterparts while considering associated factors., Methods: We used the data from the cross-sectional Mental Health in the General Population survey in the only 3 sites for which information on indigenous status was available: Noumea (2006) and the 'Bush' (2008) in New Caledonia, and French Polynesia (2015-2017). Current mental health issues were screened using the Mini-International Neuropsychiatric Interview . In multivariable analyses, we considered the following factors: gender, age, education level, marital status, occupational activity and monthly income., Results: Overall, 2294 participants were analysed. Among the 1379 indigenous participants, 52.3% had at least one mental health issue. The prevalence of depressive disorder (18.0% vs 11.7%), alcohol use disorder (16.7% vs 11.7%) and suicide risk (22.3% vs 16.7%) were higher among indigenous participants compared to non-indigenous participants. After adjustment, the association between indigenous status and these mental health issues did not persist, except for alcohol use disorder., Conclusion: We found higher prevalence of depressive disorder, alcohol use disorder and suicide risk among indigenous people of French Polynesia and New Caledonia compared to their counterparts. These differences seemed largely explained by socioeconomic disparities. Future studies could explore the use of and access to healthcare by indigenous populations., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article.

Background: Prevention strategies for suicide emphasize restrictions on firearm access. These restrictions may lose efficacy if individuals substitute other lethal suicide methods. Aims: The objective of this study is to determine the extent to which individuals who die by suicide in the United States substitute hanging for firearm injury. Methods: This study is a repeated cross-sectional analysis of suicide deaths in the United States from 2003 to 2021. Multiple regression was used to estimate the effect of firearm access proxies on individual suicide methods (hanging vs. firearm injury). Results: The probability of death by hanging was significantly and negatively associated with proxies of firearm access. Limitations: This study does not compare crude rates of suicide by state, which rise on average with rates of firearm ownership. The National Violent Death Reporting System expanded over the sample period, so early years have incomplete ascertainment. Rates of gun ownership and gun safety law scales are measured as proxies. Conclusions: Although means restriction around firearm access is a critical tool for suicide prevention, complementary strategies for prevention around hanging merit further study.

Aim: Adolescents and young adults are vulnerable to suicidality, especially those at high risk such as young people who use drugs (YPUD). This study aimed to assess the prevalence and related factors of suicide risk among this population., Methods: We conducted a descriptive, cross-sectional study on YPUD aged 16-24 in the community in Hanoi, Vietnam. Data on socio-demographic characteristics, drug use, and adverse childhood experiences were collected using face-to-face questionnaires by research assistants. YPUD were screened by psychiatrists for depression, psychotic symptoms, and suicide risk, using the MINI questionnaire., Results: Three hundred-seven YPUD (250 males, 57 females) participated in the study; of those, 86 (28.0%) were at risk of suicide. Gender (female), adverse childhood experiences, depression, and psychosis were relevant factors., Conclusion: The prevalence of suicide risk among young people using drugs was high. Therefore, suicide risk should be screened and monitored in the clinical assessment of this population. In addition, the intervention efforts to detect and intervene in adverse events during childhood may be one way to prevent mental health and suicide in later life., (© 2024 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Previous epidemiological studies have reported a short-term association between ambient temperature and suicide risk. To gain a clearer understanding of this association, it is essential to differentiate the risk factors for intentional self-harm (ISH) from those specifically associated with suicide deaths. Therefore, this study aims to examine whether the association between daily temperature and ISH or suicide deaths differs by age and sex. Between 2014 and 2019, cases of emergency room visits related to ISH and suicide deaths in Seoul were identified. A time-stratified case-crossover design was used to adjust for temporal trends and seasonal variation. A distributed lag nonlinear model was used to analyze the nonlinear and time-delayed effect of ambient temperature on ISH and suicide deaths. Positive associations were observed between temperature and both ISH and suicide deaths. For ISH, the relative risk (RR) was high at 1.17 (95% confidence interval (CI): 1.03, 1.34) for a temperature of 25.7 °C compared with 14.8 °C. The RR for suicide death was higher than those for ISH, at 1.43 (95% CI: 1.03, 2.00) for a temperature of 33.7 °C. These associations varied by age and sex, with males and females aged 35-64 years showing increased susceptibility to suicide deaths. This study provides detailed evidence that unusually high temperatures, both anomalous and out of season, may trigger suicidal behaviors, including both ISH and suicide deaths., (© 2024.

Objective: To investigate the mediating role of depressive symptoms in the relationship between negative life events (NLEs) and suicidality, as well as to test the moderating effect of self-esteem in the mediation model., Methods: A total of 3,003 adolescents from Han, Tibetan, and Yi ethnic groups living in Western China were included in this study. Utilizing the structural equation model, a mediation model and a moderated mediation model were constructed., Results: The presence of NLEs was positively associated with suicidality (β = 0.17, p < 0.001). Depressive symptoms partially mediated the relationship between NLEs and suicidality (indirect effect β = 0.19, p < 0.001). Self-esteem moderated both the antecedent and subsequent segments of the mediating paths of "NLEs → depressive symptoms → suicidality" and the direct relationship between NLEs and suicidality. Among adolescents with a low level of self-esteem, the mediating effect coefficient of depressive symptoms was higher at 0.18 (95% confidence interval (CI): 0.14-0.23), in contrast to adolescents with a high level of self-esteem, where the mediating effect coefficient of depressive symptoms was 0.04 (95% CI: 0.02-0.07)., Conclusion: NLEs are directly associated with an increased risk of suicidality and indirectly related to suicidality by increasing the risk of depressive symptoms among adolescents. Self-esteem can moderate the mediating effect of depressive symptoms and the relationship between NLEs and suicidality. The intervention strategy for preventing suicidality among adolescents who have experienced NLEs should focus on reducing depressive symptoms and improving self-esteem., (© 2024.

Purpose: The effects of the COVID-19 pandemic on mental health issues such as depression and anxiety are well-documented in the literature, but its influence on suicidal patterns shows divergent results. We aim to comprehensively synthesize evidence on potential changes or stability of suicide rates during the COVID-19 pandemic worldwide., Methods: A comprehensive search of studies reporting suicide rates before and during the COVID-19 pandemic was conducted. Eligible studies reported incidences of confirmed suicides (suspected in special cases) for two time periods, before (until February 2020) and during (from March 2020 to June 2021) the COVID-19 pandemic. A meta-analysis of proportions using a random-effect model was performed to estimate the pre- and during-pandemic incidence rates of suicide with 95% confidence intervals. Differences in pre- and during-pandemic rates were formally tested using a heterogeneity test., Results: A total of 34 studies were included in the review capturing suicide data from over 40 countries and regions. The meta-analysis outputs did not indicate a significant change in suicide rates during the COVID-19 pandemic. The pooled suicide rate in the studied period before the pandemic was 11.38 per 100,000 (95% CI 9.35-13.42) and in the period during the pandemic was 10.65 per 100,000 (95% CI 8.61-12.68)., Conclusion: No significant change in suicide rates was observed during the COVID pandemic from a global perspective for the periods examined. A longer follow-up can provide additional insights into such suicide trends globally. Improvements in data reporting, specifically with implementation of real-time surveillance, is imperative to provide adequate suicide prevention and support., (© 2024. The Author(s).)

Introduction: Few studies have examined county-level hotspots of veteran suicide and associated place-based contributors, limiting development of targeted community-level prevention strategies. The objectives of this national spatial analysis of all veteran suicides were to identify areas of the United States with higher-than-expected veteran suicide rates and determine county-level social and economic characteristics associated with areas of higher risk., Methods: Using Bayesian hierarchical modeling, county-level standardized mortality ratios for veteran suicide deaths were estimated for time periods 2011-2018, 2011-2014, and 2015-2018. Adjusted relative risk, accounting for community characteristics, for each county was then estimated and associations between community characteristics and veteran suicide risk were examined. Analyses were conducted in 2023-2024., Results: Risk of veteran suicide is predominantly concentrated in the Mountain West and West. Significant predictors of risk across all time periods were per capita number of firearm retailers (2011-2018 relative risk [RR]=1.065 [95% credible interval [CI] 1.030-1.102]), the proportion of residents who moved in the past year (2011-2018 RR=1.060 [95% CI 1.039-1.081]), the proportion of residents who live alone (2011-2018 RR=1.067 [95% CI 1.046-1.089]), the proportion of residents in rental housing (2011-2018 RR=1.041 [95% CI 1.018-1.065]), and the proportion of married residents (2011-2018 RR=0.915 [95% CI 0.890-0.941])., Conclusions: This study contributes to a comprehensive public health approach to veteran suicide prevention by identifying where resources are needed most, and which place-based intervention targets have the largest potential for impact. Findings suggest that public health efforts to address suicide among veterans should address community-level firearm access and identify ways to alleviate deleterious effects of social fragmentation., (Published by Elsevier Inc.)

Aim: To evaluate the potential association between suicidality and glucagon-like peptide-1 receptor agonists (GLP-1RAs), as well as other medications used for obesity and diabetes, using comprehensive global data., Materials and Methods: This study utilized the World Health Organization's pharmacovigilance database, encompassing adverse drug reaction reports from 1967 to 2023, from 170 countries (total reports, N = 131 255 418). We present the reported odds ratios (RORs) with 95% confidence intervals (CIs) and information component (IC) with IC 025 regarding the association between GLP-1RA use and suicidality., Results: Although reports of GLP-1RA-associated suicidality increased gradually from 2005 to 2023 (n = 332), no evidence of an association was observed (ROR 0.15 [95% CI 0.13 to 0.16]; IC -2.77 [IC 025 -2.95]). The lack of evidence of an association persisted regardless of whether GLP-1RAs were used for diabetes treatment (ROR 0.13 [95% CI 0.11 to 0.14]; IC -2.95 [IC 025 -3.14]) or obesity treatment (ROR 0.44 [95% CI 0.34 to 0.58]; IC -1.16 [IC 025 -1.62]). However, an association was found between suicidality and other diabetes medications excluding GLP-1RAs (ROR 1.13 [95% CI 1.10 to 1.15]; IC 0.17 [IC 025 0.13]). Similarly, the potential association with suicidality was observed in medications used to treat obesity excluding GLP-1RAs (ROR 1.08 [95% CI 1.01 to 1.14]; IC 0.10 [IC 025 0.01])., Conclusions: The suspected association between GLP-1RA use and suicidality, as raised by the European Medicines Agency, was not found in our global analysis. This indicates that the sporadic reports of GLP-1RA-associated suicidality are likely influenced by factors such as comorbidities present in the GLP-1RA user population., (© 2024 John Wiley & Sons Ltd.)

Introduction: Suicide is a major public health concern in low- and middle-income countries (LMICs) due to its substantial psychological, social, and economic impact. There is little synthesized evidence to estimate the economic burden of suicide and suicide attempts in such economies. The present systematic literature review aims to examine existing evidence on the cost of illness (COI) in the case of suicides and suicide attempts and assess their quality., Methods: A systematic review was carried out using electronic databases, such as Medline, EMBASE, EconLit, PsycINFO, and CINAHL using keywords like 'suicide and suicide attempts,' 'cost of illness,' and economic burden." The quality assessment of studies was conducted along with the per-person cost estimation to understand the variation of methods followed across the studies., Result: 14 studies qualified for final data extraction and synthesis out of 4,164 studies. The studies showed heterogeneity across objectives, settings, and methods, with cost estimates reflecting a wide range of costings per person in suicide and suicide attempts., Conclusion: It is challenging to determine and compare the economic estimates of suicide. Intensive research is warranted with standardized cost assessment techniques and wider perspectives to understand the true economic burden of suicide., Registration: PROSPERO Registration No- CRD42022294080.

Objective: The authors evaluated associations between employment at discharge from Veterans Health Administration Vocational Rehabilitation Service (VR) programs and suicide and other causes of death., Methods: For veterans receiving VR between October 1, 2005, and September 30, 2014 (N=78,293), proportional hazards analyses were used to test associations of employment with suicide, drug overdose, and external and natural cause mortality rates over 1 and 5 years postdischarge and through December 31, 2019. The analyses were adjusted for clinical and sociodemographic characteristics and propensity for employment., Results: Of the veterans, 94.1% had a psychiatric diagnosis, and 35.5% were employed at VR discharge. In proportional hazards analyses, employment was associated with lower mortality rates through 1 year (suicide, hazard ratio [HR]=0.54; overdose, HR=0.70; external causes, HR=0.62; and natural causes, HR=0.51) and 5 years postdischarge (overdose, HR=0.72; external causes, HR=0.81; and natural causes, HR=0.72). Through December 31, 2019, employment was associated with lower risks for overdose (HR=0.80) and death by external (HR=0.81) and natural (HR=0.80) causes., Conclusions: Employment at VR discharge was associated with lower mortality risk among veterans with psychiatric diagnoses., Competing Interests: The authors report no financial relationships with commercial interests.

Purpose: Suicide is a leading cause of death in prison and the suicide rates are several times higher in the prison population than in the general population in most countries. Of the studies that have investigated risk factors for suicide in prison, few have controlled for possible confounding factors. The aim of this study is to identify risk factors of suicide among people in French prisons, over a four-year period., Methods: All incarcerations that occurred in France during 2017-2020 were eligible. Sociodemographic, criminal and prison characteristics were collected for each incarceration from data of the National Prison Service. Survival univariate and multivariate analyses were performed with a Cox regression model., Results: 358,522 incarcerations were included, of which 449 ended in suicide during the follow-up. The median length of prison stay was 5.1 months. The median age at prison entry was 30 years and 95.8% of incarcerations involved men. The overall suicide rate was 173 [157-189] per 100,000 person-years. Factors associated with suicide in the multivariate model (p < 0.05) were the early stage of incarceration and in particular the first week (HR = 7.6 [5.4-10.8]), violent offences and in particular homicide (HR = 3.0 [2.1-4.2]), French (HR = 1.7 [1.2-2.4]) and other European nationalities (HR = 2.1 [1.4-3.3]), age above 40 (HR = 2.0 [1.5-2.6]), pre-trial incarceration (HR = 1.8 [1.4-2.3]), being separated (HR = 1.6 [1.1-2.3] and having a high school diploma (HR = 1.4 [1.0-1.8])., Conclusions: Factors associated with suicide in prison are complex and involve individuals' criminal history as well as conditions of incarceration. These characteristics may be relevant to focus suicide prevention efforts., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany.)

Background: Decreasing suicide mortality has become an overarching goal for societies worldwide. Suicide registers and other monitoring systems are a valuable source of information that can be used for addressing the suicide phenomenon and evaluating preventative interventions., Aims: This scoping review provides an overview of literature published in the last decade that has focussed on the operations (functioning) and characteristics of suicide registers and other suicide monitoring systems., Methods: Four electronic databases were searched in 2020 for identifying published material from January 2010 to October 2020. The searches were updated in October 2023 to include material from 2020 to date. Grey literature through Google searches and mental health commissions websites and the reference lists of selected documents were also searched., Results: Twenty-five articles were included in this review. Nearly half the articles were from the United States, followed by Australia. Nine countries were identified as having used suicide registers or suicide-specific monitoring systems to inform suicide prevention. Monitoring mechanisms varied across the countries examined. No article provided evidence that definitively linked suicide registers or other monitoring systems for suicide with the prevention of suicide or reduction in suicide rates. However, a variety of benefits of suicide monitoring for preventative and public health interventions were identified., Conclusions: The number of nations with surveillance systems for suicide prevention is low. Further, there is a lack of consistency in the systematic collection, analysis and interpretation of suicide-related information across the countries examined. Efforts to establish high-quality suicide surveillance systems that can be accessed in a timely and easy manner are needed to inform tailored strategies for suicide prevention.

Introduction: Over 40,000 people die by suicide annually in the U.S., and firearms are the most lethal suicide method. There is limited evidence on the effectiveness of many state-level policies on reducing firearm suicide. The objective of this study was to identify public policies that best predict state-level firearm suicide rates., Methods: Data from the Centers for Disease Control and Prevention's WONDER system and the State Firearm Law Database, a longitudinal catalog of 134 firearm safety laws, were analyzed. The analysis included 1,450 observations from 50 states spanning 1991-2019. An ElasticNet regression technique was used to analyze the relationship between the policy variables and firearm suicide rates. Nested cross-validation was performed to tune the model hyperparameters. The study data were collected and analyzed in 2023 and 2024., Results: The optimized ElasticNet approach had a mean squared error of 2.07, which was superior to nonregularized and dummy regressor models. The most influential policies for predicting the firearm suicide rate on average included laws requiring firearm dealers that sell handguns to have a state license and laws requiring individuals to obtain a permit to purchase a firearm through an approval process that includes law enforcement, among others., Conclusions: On average, firearm suicide rates were lower in state-years that had each influential policy active. Notably, these analyses were ecological and noncausal. However, this study was able to use a supervised machine learning approach with inherent feature selection and many policy types to make predictions using unseen data (i.e., balancing Lasso and Ridge regularization penalties)., (Copyright © 2024 Elsevier Inc.

Background: Real-time suicide registers are being established in many countries and enable regular monitoring of suspected suicides over time. The use of these data to monitor for suicide clusters is in its infancy. Aims: We sought to test the feasibility of using real-time suicide register data to detect spatiotemporal suicide clusters. Method: Using the Victorian Suicide Register and SaTScan's spatiotemporal scan statistic, we simulated a monthly search for clusters from January 2015 to June 2022 using rolling 2-year windows of data in each search. Monthly scans were performed at three different levels of geographic granularity and for all-ages and under-25 populations. Results: Our results indicated the rapid identification of possible suicide clusters and demonstrated a practical approach to combining real-time suicide data and scanning algorithms. We developed new model outputs that showed cluster timelines. Limitations: The main limitations are that the computational burden of fitting multiple models meant we were unable to scan for ellipses and other irregular shapes and we were unable to consider space-time permutation models. Conclusions: Using data from a real-time suicide register, we were able to scan for space-time suicide clusters simulating the situation where the data are updated monthly with new updates.

Objective: The suicide crisis syndrome (SCS), an acute negative affect state predictive of near-term suicidal behavior, is currently under review for inclusion as a suicide-specific diagnosis in the Diagnostic and Statistical Manual of Mental Disorders ( DSM ). While the SCS has ample psychometric validation, it is critical to test its utility as a clinical tool within a real-world clinical setting. The present study investigates patterns of emergency department (ED) readmissions following implementation of an SCS-based risk assessment tool into the ED of a large, urban hospital system., Methods: Patterns of readmission rates to the ED in the 3 months following initial ED visit were evaluated for patients diagnosed with the SCS, after controlling for suicidal ideation (SI), self-harm behavior (SHB), and psychosis in the initial ED visit. All diagnoses were extracted from the electronic medical record. SCS diagnosis was based on the Abbreviated SCS Checklist (A-SCS-C), a clinician administered rating scale., Results: Analysis of the SCS was performed on 213 patients consecutively admitted to the ED 9 months post-implementation of the A-SCS-C. Over one third (79; 37%) of patients were diagnosed with the SCS, over half 111 (52.1%) presented with SI and 8 (3.8%) with suicide attempt. After controlling for covariates, SCS diagnosis reduced readmission risk by approximately 72% (AOR = 0.281) for any reason and almost 75% (AOR = 0.257) for suicidal presentations, while SI and SHB upon initial ED visit either increased readmission risk or were noncontributory. The protective effect of the SCS was consistent across levels of severity of both SI and SHB., Conclusion: Use of the SCS appears to improve clinical outcome with suicidal patients presenting to the ED., (© Copyright 2024 Physicians Postgraduate Press, Inc.)
