The risk of repeated suicidal presentations following residential treatment for substance use disorders: A recurrent event analysis using linked administrative data. J Affect Disord 2024; 360:364-375. [PMID: 38810779 DOI: 10.1016/j.jad.2024.05.129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 05/10/2024] [Accepted: 05/25/2024] [Indexed: 05/31/2024]
Abstract
BACKGROUND Individuals seeking alcohol and other drug (AOD) treatment consistently experience higher rates of suicidal behaviours and death by suicide when compared to the general population. By linking residential AOD treatment data to administrative healthcare and death datasets, we aimed to examine suicide-related behaviours and identify risk and protective factors for these events following discharge from residential treatment. METHODS Participants included 1056 individuals aged 18-69 (M = 32.06, SD = 9.55, male = 696,65.9 %) admitted to three residential treatment facilities in Queensland, Australia from January 1, 2014 to December 31, 2016. Treatment data was linked to administrative hospital, emergency department (ED), mental health service, and Registry of Deaths data 2-years post-discharge. ICD-10 codes were used to identify and analyse suicide-related events. RESULTS Within 2-years post-discharge, 175 (16.6 %) individuals had a suicide-related event (n = 298 episodes). The highest proportion of episodes (11.1 %) occurred within 1-month of discharge. Higher risk of a recurrent suicide-related event was associated with receiving a Disability Support Pension (aHR = 1.69 (95%CI:1.10,2.59), two or more previous episodes of residential AOD treatment (aHR = 1.49 (95%CI:1.30,2.15). Completing residential treatment was associated with a lower risk of suicide-related events (aHR = 0.54 (95%CI:0.35,0.83). LIMITATIONS The amalgamation of suicidal ideation, attempts, and death into a single outcome oversimplifies their complex nature and interplay. The exclusive focus on one service provider limits generalisability, and data constraints and missingness preclude many analyses. CONCLUSIONS Understanding suicidal behaviours and critical risk periods following discharge from residential treatment is crucial for improving continuing care, developing effective suicide prevention, and implementing targeted interventions among this high-risk population.

Abstract
BACKGROUND Suicide rates have been high in several health-care professions. Suicide rates were described in physicians, dentists, veterinarians, psychologists, pharmacists, nurses, as well as theologians, other graduates and the general population in Norway. METHODS Data on educational attainment were linked to data on suicide and all-cause mortality from 1980 to 2021. Suicide rates were reported per 100,000 person-years. The total number of person-years included in the study was 66.4 and 67.2 million for males and females, respectively. RESULTS Between 1980 and 2021, male veterinarians (35.9, 95 % CI 19.3-52.4), physicians (25.7, 21.3-30.2) and nurses (22.2, 16.6-27.7) had higher suicide rates compared others with higher education (11.7, 10.7-12.7). For females, this was the case for psychologists (15.0, 8.2-21.7) and nurses (9.3, 8.3-10.3), vs. others with higher education (5.1, 4.2-6.0). Suicide rates declined over the four decades for most groups. For physicians, suicide rates declined and approached the suicide rate of others with higher education. Suicide rates among physicians increased with age, with physicians over 60 years having twice as high suicide rates compared to others with higher education. LIMITATIONS The study included only educational status, not current occupation or employment status. This is a descriptive study, with some known risk factors for suicide not accounted for. CONCLUSIONS Suicide rates for physicians declined over time, but not for nurses. From 2010 to 2021, nurses of both genders was the only group with higher suicide rates compared to other graduates. The increased suicide rates among veterinarians, nurses, female psychologists and elderly physicians are concerning.

Abstract
Substance addiction (SA) is a risk factor of suicidal thoughts and behaviors (STB), although it is still unclear which SAs are reliably associated with increased risk for suicidal ideation, planning, and attempt. The current study aimed to meet this goal using data from the National Survey on Drug Use and Health (NSDUH) referring to years from 2008 to 2020. The information extracted included sociodemographic and contextual information, eleven SAs (e.g., nicotine, alcohol, marijuana, cocaine, pain relievers, heroin, inhalants, hallucinogens, sedatives, stimulants, and tranquillizers), and STB. The analysis revealed that SAs for alcohol, pain relievers, marijuana, and cocaine were stable and reliable predictors for STB (e.g., suicidal ideation, planning, and attempt), while cocaine was not a stable predictor for suicide attempt. The selected SAs model showed a greater predictive accuracy than only sociodemographic and contextual factors as well as not selected SAs. Moreover, selected SAs showed comparable predictive accuracy to the full model. Furthermore, SA to alcohol showed to be an extremely effective predictor of STB, having a comparable predictive accuracy to all the other ten SAs together. In conclusion, SAs to pain relievers, alcohol, marijuana, and cocaine can be considered as important risk factors for concurrent STB.

Abstract
BACKGROUND AND AIMS Alcohol use disorder (AUD) is one of the strongest predictors of suicidal behavior. Here, we measured risk of suicide attempt and death as a function of AUD typologies. DESIGN We used AUD typologies from previous latent class analysis: (i) externalizing subtype (characterized by externalizing symptomatology and early age of onset; individuals in this group have lower education and higher familial/social difficulties); (ii) subtype described by minimal psychopathology; and (iii) internalizing subtype (characterized by internalizing symptomatology and later age of onset; individuals in this group have higher education). We used class membership to predict distal outcomes (attempt and death) and performed regressions to evaluate whether differences in suicidal behavior were explained by the group characteristics (sex, age of onset, number and type of AUD registrations, familial/genetic risk for AUD, externalizing and internalizing behaviors, socio-economic indicators, marital status and childhood family status). We also evaluated the effect of suicide attempt prior to AUD. SETTING AND PARTICIPANTS Based on longitudinal Swedish registry data, we included 217 074 individuals with AUD born 1950-80. MEASUREMENTS Suicide attempts were identified using medical registers and deaths using the mortality register. FINDINGS Individuals with the externalizing subtype had higher risks of suicidal behavior than other groups [attempt: externalizing versus minimal psychopathology: odds ratio (OR) = 1.35, 95% confidence interval (CI) = 1.35, 1.35; externalizing versus internalizing: OR = 1.47, 95% CI = 1.46, 1.48; death: externalizing versus minimal psychopathology: OR = 1.57, 95% CI = 1.57, 1.58; externalizing versus internalizing: OR = 1.99, 95% CI = 1.93, 2.06]. Individuals with minimal psychopathology had higher risks than those with internalizing symptomatology (attempt: OR = 1.09, 95% CI = 1.08, 1.10, death: OR = 1.26, 95% CI = 1.23, 1.30). These differences were explained by age at registration and were related to the number of registrations, sex, education, family disruption and suicide attempt prior to AUD. CONCLUSIONS Among people in Sweden, considering alcohol use disorder (AUD) heterogeneity appears to be a meaningful way to evaluate suicide risk. The highest risk of suicide attempt and death occurs in the externalizing subtype of AUD, followed by the minimal psychopathology subtype, and then the internalizing subtype.

Abstract
BACKGROUND Since 2010, heroin-assisted treatment (HAT) has been one of the treatment options available to people with opioid use disorder (OUD) in Denmark. This study aimed to characterize HAT patients at treatment start and compare their individual characteristics to those of patients entering traditional opioid maintenance treatment (OMT) with methadone or buprenorphine during the same period. METHODS Patients who initiated HAT or OMT with methadone or buprenorphine in Denmark from 2010 to 2018 were included (n=6798). Multiple national registers were linked to compare treatment groups in terms of socio-demographic variables, previous OUD treatment episodes, hospital-based care, and criminal conviction history. RESULTS Nearly all HAT patients had a history of methadone treatment (91%) and half had residential treatment experience (48%). In the year previous to admission, HAT patients recorded the highest percentages of non-fatal overdoses (12%) and chronic hepatitis C diagnoses (16%), and the lowest percentages of psychiatric disorders (11%) compared to traditional OMT patients. Criminal convictions were also common: 39% of the HAT group had committed a property crime and 18% a drug-related crime the year before HAT entry. During the study period, an overall reduction in OMT enrollments for each year was recorded. The HAT proportion to the total remained fairly stable (4%-10%), while the buprenorphine proportion increased. CONCLUSIONS In Denmark, OMT patients exhibited numerous vulnerabilities at treatment start, and among the patient groups, HAT patients were the most burdened. HAT seems to reach the target group and adhere to formulated eligibility criteria.

Abstract
OBJECTIVE This study aimed to identify trajectories of service use during the last year before suicide death and the characteristics associated with the trajectories in patients with substance use disorders. METHODS This study used a national registry data linkage, which included all patients with substance use disorders who died by suicide in Norway between 2010 and 2018. In- and outpatient contacts with mental health or substance use services during the last year before suicide death was analyzed by week using Sequence State Analysis and cluster analysis to identify trajectories. Logistic regression was used to measure the association between the characteristics and the trajectories. RESULTS We identified four trajectories of service contact. A brief contact trajectory (n = 366) with a low proportion of weeks in contact (M weeks = 8.3), associated with less psychosis or bipolar disorder (aOR = 0.13 (0.08-0.22)) and higher age. A regular contact trajectory (n = 160), with a higher proportion of contact (M weeks = 47.9), associated with psychosis or bipolar disorder (aOR = 3.66 (2.10-6.47)) and depressive or anxiety disorder (aOR = 3.11 (1.93-5.13)). An intermittent contact trajectory (n = 195) with most contacts with outpatient substance use disorder services (M weeks = 9.7). A continuous contact trajectory (n = 109) with a high proportion of inpatient contact (M weeks = 44.5), strongly associated with psychosis or bipolar disorder (aOR = 6.08 (3.26-11.80)). CONCLUSION Longitudinal descriptions of service use reveal different trajectories that are important to consider when developing policies or interventions to reduce the risk of suicide death in patients with substance use disorders.

Abstract
BACKGROUND Suicidal behavior and substance use disorders (SUDs) are important public health concerns. Prior suicide attempts and SUDs are two of the most consistent predictors of suicide death, and clarifying the role of SUDs in the transition from suicide attempt to suicide death could inform prevention efforts. METHODS We used national Swedish registry data to identify individuals born 1960-1985, with an index suicide attempt in 1997-2017 (N = 74 873; 46.7% female). We assessed risk of suicide death as a function of registration for a range of individual SUDs. We further examined whether the impact of SUDs varied as a function of (i) aggregate genetic liability to suicidal behavior, or (ii) age at index suicide attempt. RESULTS In univariate models, risk of suicide death was higher among individuals with any SUD registration [hazard ratios (HRs) = 2.68-3.86]. In multivariate models, effects of specific SUDs were attenuated, but remained elevated for AUD (HR = 1.86 95% confidence intervals 1.68-2.05), opiates [HR = 1.58 (1.37-1.82)], sedatives [HR = 1.93 (1.70-2.18)], and multiple substances [HR = 2.09 (1.86-2.35)]. In secondary analyses, the effects of most, but not all, SUD were exacerbated by higher levels of genetic liability to suicide death, and among individuals who were younger at their index suicide attempt. CONCLUSIONS In the presence of a strong predictor of suicide death - a prior attempt - substantial predictive power is still attributable to SUDs. Individuals with SUDs may warrant additional suicide screening and prevention efforts, particularly in the context of a family history of suicidal behavior or early onset of suicide attempt.

Abstract
BACKGROUND The time after contact with specialized health services for mental health and substance use is associated with an increased risk of suicide, where temporal aspects of suicide and comorbid mental disorders in patients with substance use disorders could be associated. This study aimed to examine the temporal association between time from last treatment contact to suicide and comorbid mental disorders in patients with substance use disorders. METHODS This study is a historical prospective case series using nationwide registry data. It included 946 individuals registered the year before suicide with a substance use disorder (F10-F19) in Norway's specialized health services for treating substance use and mental health disorders between 2010 and 2020. The outcome was the number of weeks from the last contact with services to suicide. The exposure was comorbid mental disorders divided into 'no comorbid mental disorder'; 'psychosis or bipolar disorders' (F20-F31), 'depressive or anxiety disorders' (F32-F49); and 'personality disorders' (F60-F69). Covariates included gender, age, last diagnosed substance use disorder, registered deliberate self-harm last year, and the number of in- and outpatient contacts the previous year. RESULTS The number of weeks from last service contact to suicide differed (p = < 0.001) between patients with no comorbid mental disorders (Median = 7; IQR 2-23), psychosis or bipolar disorders (Median = 2; IQR = 1-7), depressive or anxiety disorders (Median = 3; IQR = 1-11) and personality disorders (Median = 1; IQR = 1-5.5). Significantly decreased adjusted incidence rate ratios (aIRR) were found for psychosis or bipolar disorders [aIRR = 0.67 (95% CI 0.53-0.85)] and personality disorders [aIRR = 0.56 (0.42-0.77)] compared to no comorbid mental disorder when adjusted for individual characteristics and service contact. For depressive and anxiety disorders compared to no comorbid mental disorder, the association was significant when adjusted for individual characteristics [aIRR = 0.55 (0.46-0.66)]. CONCLUSIONS While patients with substance use disorders generally died by suicide a short time after contact with services, patients with comorbid mental disorders died an even shorter time after such contact and significantly shorter than patients without such comorbidities.

Abstract
BACKGROUND Suicide is a significant contributor to global mortality. People who use drugs (PWUD) are at increased risk of death by suicide relative to the general population, but there is a lack of information on associated candidate factors for suicide in this group. The aim of this study was to provide a comprehensive overview of existing evidence on potential factors for death by suicide in PWUD. METHODS A scoping review was conducted according to the Arksey and O'Malley framework. Articles were identified using Medline, CINAHL, PsycINFO, SOCIndex, the Cochrane Database of Systematic Reviews and the Campbell Collaboration Database of Systematic Reviews; supplemented by grey literature, technical reports, and consultation with experts. No limitations were placed on study design. Publications in English from January 2000 to December 2021 were included. Two reviewers independently screened full-text publications for inclusion. Extracted data were collated using tables and accompanying narrative descriptive summaries. The review was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. RESULTS The initial search identified 12,389 individual publications, of which 53 met the inclusion criteria. The majority (87%) of included publications were primary research, with an uncontrolled, retrospective study design. The most common data sources were drug treatment databases or national death indexes. Eleven potential factors associated with death by suicide among PWUD were identified: sex; mental health conditions; periods of heightened vulnerability; age profile; use of stimulants, cannabis, or new psychoactive substances; specific medical conditions; lack of dual diagnosis service provision; homelessness; incarceration; intravenous drug use; and race or ethnicity. Opioids, followed by cannabis and stimulant drugs were the most prevalent drugs of use in PWUD who died by suicide. A large proportion of evidence was related to opioid use; therefore, more primary research on suicide and explicit risk factors is required. CONCLUSIONS The majority of studies exploring factors associated with death by suicide among PWUD involved descriptive epidemiological data, with limited in-depth analyses of explicit risk factors. To prevent suicide in PWUD, it is important to consider potential risk factors and type of drug use, and to tailor policies and practices accordingly.

INTRODUCTION Among people receiving current or previous opioid maintenance treatment (OMT), the leading cause of premature death is an opioid overdose. However, other causes of mortality remain high in this group. An understanding of causes of deaths across multiple settings can be useful in informing more comprehensive prevention responses. The aim of this study was to describe all non-overdose causes of death in three national cohorts (Czechia, Denmark, and Norway) among OMT patients and to explore associations of non-overdose mortality with age and gender. METHODS This prospective comparative cohort study used national mortality registry databases for OMT patients from Czechia (2000-2019), Denmark (2000-2018), and Norway (2010-2019). Crude mortality rates and age-standardized mortality rates (ASMRs) were calculated as deaths per 1,000 person years for cause-specific mortality. RESULTS In total, 29,486 patients were included, with 5,322 deaths recorded (18%). We found variations in causes of death among the cohorts and within gender and age groups. The leading non-overdose causes of death were accidents in Czechia and Denmark, and neoplasms in Norway. Cardiovascular deaths were highest in Czechia, particularly for women in OMT (ASMR 3.59 vs. 1.24 in Norway and 1.87 in Denmark). CONCLUSION This study found high rates of preventable death among both genders and all age groups. Different demographic structures, variations in risk exposure, as well as variations in coding practices can explain the differences. The findings support increased efforts towards screening and preventative health initiatives among OMT patients specific to the demographic characteristics in different settings.

Abstract
BACKGROUND Previous studies have demonstrated substantial associations between substance use disorders (SUD) and suicidal behavior. The current study empirically assesses the extent to which shared genetic and/or environmental factors contribute to associations between alcohol use disorders (AUD) or drug use disorders (DUD) and suicidal behavior, including attempts and death. METHODS The authors used Swedish national registry data, including medical, pharmacy, criminal, and death registrations, for a large cohort of twins, full siblings, and half siblings (N = 1 314 990) born 1960-1980 and followed through 2017. They conducted twin-sibling modeling of suicide attempt (SA) or suicide death (SD) with AUD and DUD to estimate genetic and environmental correlations between outcomes. Analyses were stratified by sex. RESULTS Genetic correlations between SA and SUD ranged from rA = 0.60-0.88; corresponding shared environmental correlations were rC = 0.42-0.89 but accounted for little overall variance; and unique environmental correlations were rE = 0.42-0.57. When replacing attempt with SD, genetic and shared environmental correlations with AUD and DUD were comparable (rA = 0.48-0.72, rC = 0.92-1.00), but were attenuated for unique environmental factors (rE = -0.01 to 0.31). CONCLUSIONS These findings indicate that shared genetic and unique environmental factors contribute to comorbidity of suicidal behavior and SUD, in conjunction with previously reported causal associations. Thus, each outcome should be considered an indicator of risk for the others. Opportunities for joint prevention and intervention, while limited by the polygenic nature of these outcomes, may be feasible considering moderate environmental correlations between SA and SUD.

Abstract
OBJECTIVE This study identified patient clinical and sociodemographic characteristics, and, more originally, service use patterns as predictors of death from physical illness or accidental/intentional causes. METHODS A cohort of 19,015 patients with substance-related disorders (SRD) from 14 addiction treatment centers was investigated using Quebec (Canada) health administrative databases. Death was studied over a 3-year period (April 1, 2013, to March 31, 2016), and most predictors from 4 years to 12 months prior to the time of death, using multinomial logistic regression. RESULTS Frequent emergency department (ED) use strongly predicted both causes of death, suggesting that outpatient care responded inadequately to patient needs. Only receipt of specialized SRD and psychiatric care significantly decreased the risk of death from physical illness, with trends toward significance for accidental/intentional death. Hospitalization, greater material deprivation and having SRD-chronic physical illnesses or alcohol-related disorders most strongly predicted risk of death from physical illness. Sociodemographic characteristics, mainly social deprivation, were more likely to predict accidental/intentional death. CONCLUSIONS Outpatient services could be improved by increasing outreach and motivational interventions and, for ED and hospital units, better screening, brief intervention, and referral to treatment, particularly for men and socially deprived patients at high risk of accidental/intentional death. Patients with more severe health conditions, notably older or materially deprived men at higher risk of death from physical illness, could benefit from programs like assertive community treatment or intensive case management that respond well to diverse and continuous patient needs. Collaborative care between SRD and health services could also be improved.

Abstract
INTRODUCTION Suicide is a complex transdiagnostic phenomenon. It is strongly associated with, but not exclusive to major depressive disorder (MDD). Hazardous alcohol drinking has also been linked to an increased risk of suicidal behaviours, however, it is often underreported. The study aimed to evaluate whether an objective measure of chronic alcohol use, phosphatidylethanol (PEth) could be useful as a biomarker in clinical practice. METHOD ology. The present case-control multi-centric study recruited 156 participants into three study groups: 52 patients treated for major depressive disorder (MDD), 51 individuals immediately following a suicide attempt (SA), and 53 volunteers. Sociodemographic data, medical history, and laboratory data, including PEth concentrations and C-reactive protein levels, were collected from study participants. RESULTS PEth concentrations were the highest in suicide attempters (232,54 ± 394,01 ng/ml), followed by patients with MDD (58,39 ± 135,82 ng/ml), and the control group (24,45 ± 70,83 ng/ml) (Kruskall Wallis χ2 = 12.23, df = 2, p = .002). In a multinomial logistic regression model with adjustments, PEth concentration was able to predict belonging to suicide attempters' group, but not to depression group (p = .01). Suicide attempters were also more likely to underreport their recent alcohol consumption. LIMITATIONS We did not analyze SA methods, psychiatric comorbidity and several other factors that might be associated with PEth levels, such as body mass index, race, and haemoglobin levels. Sample recruited in hospital settings may not be representative of the whole population. The results of this adult-only study cannot be generalized to adolescents. CONCLUSIONS PEth levels in recent suicide attempters significantly exceeded those of patients with MDD and controls. Suicide attempters also were more likely to underreport their alcohol consumption when questioned about their consuption. PEth might be an interesting biomarker to evaluate individuals at risk of SA.

Abstract
Background: Suicide attempts are common in patients with severe psychiatric disorders; however, they are rarely studied in this population. Aims: To investigate the prevalence and risk factors associated with suicide attempts among patients with severe psychiatric disorders. Method: This is a cross-sectional study of patients admitted to the Mohammed VI University Hospital of Psychiatry in Oujda, Morocco. Results: A total of 250 patients with a psychiatric disorder were recruited in this study. Among these, 78 cases (31.2%) had a personal history of suicide attempts. A personal history of suicide attempt was significantly higher among women compared to men (45.5% vs. 27.2%, p = .0099). The most common method of suicide attempts was jumping from heights (31%). Patients with a personal history of suicide attempts had a significantly higher prevalence of alcohol consumption (p = .0063), family history of psychiatric disorders (p = .002), family history of suicide attempt (p = .00004), and family history of suicide (p = .018) compared to those who had never made suicide attempts. Limitations: As suicidal behavior is highly stigmatized in Morocco, the number of patients who have made a suicide attempt may be underestimated. Conclusion: Our findings justify the need to provide specialized support to psychiatric patients with risk factors for suicide attempts.

Abstract
Abstract
Purpose of Review
Observational studies assessing the association of cannabis use with subsequent intentional self-injury have reported mixed findings. Longitudinal studies examining the association of cannabis use with subsequent suicide death are notably rare. Our objective was to review longitudinal studies examining cannabis use and subsequent self-harm, suicide attempt, or suicide death.
Recent Findings
Few population-based studies have focused on self-harm with considerable variability across studies in how this outcome has been operationalized. Studies assessing the association between cannabis use and suicide attempt are equivocal in their conclusions and heterogenous in terms of samples utilized and assessment of confounding bias. The results of one meta-analysis were suggestive of dose dependency. For suicide death, the findings are inconsistent, and there is reason for concern of selection bias.
Summary
The existing evidence base on these associations is not yet rigorous enough to allow drawing conclusions on causality. However, cannabis might be seen as an adverse prognostic marker for intentional self-injury.

Abstract
BACKGROUND AND AIMS Substance use disorder (SUD) is related to widespread adverse consequences, including higher suicidality. Shared genetic liability has been demonstrated between SUD and suicidality. Here, we measured the factors that contribute to increased risk of non-fatal suicide attempt among individuals with SUD by focusing upon aggregate genetic risks and both childhood and past-year environmental factors. DESIGN Longitudinal study. Family genetic risk scores and environmental factors (childhood, aged from 0 to 15 years, and the year preceding SUD registration) were used to predict the relative risk of non-fatal suicide attempt using Cox proportional hazards models. Additional analyses employed a co-relative design, accounting for genetic factors and shared familial environment, to test for potential causality. SETTING AND PARTICIPANTS Based on longitudinal Swedish registry data, 228 617 individuals with SUD registrations from 1991 to 2015 were included. MEASUREMENTS SUD and suicide attempts were identified using medical records (International Classification of Diseases codes). SUD was also identified using pharmacy and criminal registries. FINDINGS In multivariable analyses that jointly accounted for all the selected potential predictors, individuals with SUD were at higher risk for non-fatal suicide attempt if they had experienced a parental death [hazard ratio (HR) = 1.58; 95% confidence interval (CI) = 1.30, 1.93], were female (HR = 1.53, 95% CI = 1.49, 1.57), had low educational attainment (HR = 1.50, 95% CI = 1.46, 1.55), received social welfare (HR = 1.21, 95% CI = 1.17, 1.25) or had lived in a non-intact family (HR = 1.11, 95% CI = 1.08, 1.14). In co-relative analyses, low education was supported as a possible causal factor for suicide attempt. Aggregate genetic risks interacted with low education and being raised in a non-intact family, with increased prevalence of suicide attempt in people with high genetic risks and unfavorable environmental exposures. CONCLUSIONS Aggregate genetic liability, childhood environmental experiences and specific socio-economic indicators are important risk factors for non-fatal suicide attempt among individuals with substance use disorder.

Abstract
INTRODUCTION Decades of research show an association between alcohol use and death by suicide. However, findings on the temporal link between alcohol use and death by suicide are unclear. In the most comprehensive meta-analysis on the topic to date, we analyzed data from longitudinal studies to determine if alcohol use is a risk for death by suicide. We also explored moderators to uncover conditions where the alcohol use-suicide link is strengthened/weakened. METHODS Our literature search of six databases yielded 33 eligible studies involving 10,253,101 participants (community, psychiatric, and military samples). RESULTS Alcohol use was associated with a 94% increase in the risk of death by suicide. Specifically, random-effects meta-analysis revealed alcohol use displayed small-to-large significant risk and odds ratios with suicide for quantity of alcohol use and alcohol use diagnosis/alcohol-related problems. Meta-regression generally indicated larger effect sizes for studies with a higher percentage of women, younger age, unadjusted estimates, longer follow-up periods, military samples, and higher frequencies and quantities of alcohol use (relative to drinker/non-drinker status). CONCLUSION Our study highlights alcohol use as a substantive risk factor for death by suicide and underscores the importance of monitoring alcohol use among suicidal individuals and screening for suicidality among heavier alcohol users.

Abstract
BACKGROUND Suicide rates among young people have been increasing in recent years, yet no validated methods are available for identifying those who are at greatest risk for suicide. Abnormalities in the medial prefrontal cortex have been previously observed in suicidal individuals, but confounding factors such as treatment and chronic illness may have contributed to these findings. Thus, in this study we tested whether the size of the medial prefrontal cortex is altered in suicidal young adults who have received no treatment with psychotropic medications. METHODS Suicidality was evaluated using the Suicide Behaviors Questionnaire-Revised (SBQ-R) and surface areas of four regions-of-interest (ROIs) within the medial prefrontal cortex were measured using magnetic resonance imaging (MRI) in a cohort of college students (n = 102). In addition, a secondary seed-based functional connectivity analysis was conducted using resting-state functional MRI data. Areas and functional connectivity of the medial prefrontal cortex of young adults with high suicidality (HS; SBQ-R score > 7; n = 20) were compared to those with low suicidality (LS; SBQ-R score = 3, n = 37). RESULTS Compared to the LS group, the HS group had a significantly lower surface area of the right frontal pole (p < 0.05, Bonferroni-corrected) and significantly lower functional connectivity of the right frontal pole with the bilateral inferior frontal cortex (p < 0.001, Monte-Carlo corrected). LIMITATION These findings require replication in a larger sample and extension in younger (adolescent) populations. CONCLUSION Diminished frontal pole surface area and functional connectivity may be linked to elevated levels of suicidality in young people.

Abstract
BACKGROUND AND AIMS Drug use disorders are associated with increased risk of self-harm. Risk differences associated with specific types of drug use disorders are yet to be comprehensively reported. This study aimed to examine the risk of self-harm or suicide associated with different drug use disorders in Hong Kong. DESIGN Population-based cohort study. SETTING The Clinical Data Analysis and Reporting System (CDARS) managed by the Hong Kong Hospital Authority. PARTICIPANTS Cases were people ages 10 years or older who visited a hospital Accident and Emergency department between 1 January, 2004 and 31 December, 2016 with any of 10 specific drug use disorders (comprising opioid; ketamine; methamphetamine; sedative, hypnotic, or anxiolytic; amphetamine or related stimulant; cocaine; cannabis; hallucinogen; unspecified or other drug; and polydrug). Each case was matched with two controls, selected from a subset of people in CDARS sharing the same gender, age and psychiatric profile. A total of 8270 cases and 16 540 matched controls were included. MEASUREMENTS Incidence and adjusted hazard ratio (aHR) of subsequent self-harm or suicide for each specific drug use disorder were estimated. FINDINGS The most prevalent drug use disorder was opioid use disorder (2523; 30.51%) and the least prevalent was hallucinogen use disorder (77; 0.93%). The crude incidence of self-harm or suicide ranged from 26.57 (95% CI, 14.23-44.55) per 1000 person-years for cannabis use disorder to 91.97 (77.32-108.37) for polydrug use disorder. The highest risk of self-harm or suicide was observed in ketamine (aHR, 16.36; 95% CI, 11.03-24.29) and opioid (15.97; 10.73-23.23) use disorders. CONCLUSIONS In Hong Kong, all types of drug use disorders appear to be significantly associated with increased risk of self-harm or suicide, but risk levels vary by type of drug use disorder.

Abstract
Suicide rates are higher for people with an opioid use disorder, compared to the general population. This study aims to characterize opioid agonist treatment entrants who present a history of suicidal ideations or suicide attempts, according to concurrent comorbidity profiles, in an opioid use disorder treatment facility. A chart review design was used. Data was collected from 202 patient files. Bivariate and multivariate analyses were conducted. In multivariate analysis, patients with a diagnosis or symptoms of a mood disorder were 2.48 [1.01 - 6.11] times more likely to report suicidal ideations and 2.64 [1.05 - 6.62] times more likely to report suicide attempts. Those with a diagnosis or symptoms of an anxiety disorder were 2.41 [1.01 - 5.81] times more likely to report suicidal ideations. Patients who report chronic pain were 2.59 [1.06 - 6.35] times more likely to report suicidal ideations as well. The probability to report suicide attempts was 5.09 [1.16 - 22.4] times higher for those with a confirmed or suspected personality disorder. Clinicians should bear in mind the high suicide rates in people with opioid use disorder, as well as the importance of addressing suicidal risk and providing easy access to mental health and chronic pain treatment as part of the service offer in opioid agonist treatment. Future research should focus on evaluating the effectiveness of treatments aimed at addressing the needs of opioid agonist treatment patients with interrelated mental health and pain comorbidity profiles to reduce risks associated with suicide.

Comparing characteristics of suicide to non-suicide drug poisoning deaths, by sex, in Ireland. J Affect Disord 2022; 306:80-89. [PMID: 35306124 DOI: 10.1016/j.jad.2022.03.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 01/17/2022] [Accepted: 03/10/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Suicide by drug poisoning is potentially preventable; however, evidence on associated risk factors by sex is limited. AIM To assist in understanding how individual and social contextual factors, and specific drugs, influence risk of suicide compared to non-suicide drug poisoning deaths, and how this differs by sex. METHODS Data were extracted from the National Drug-Related Deaths Index. Analysis included univariable and multivariable logistic regression to estimate unadjusted and adjusted odds ratios (OR) and 95% confidence intervals (CI) for factors associated with suicide drug poisoning deaths (SDPD) (primary outcome) compared with non-suicide drug poisoning deaths (NSDPD) and stratified by sex. RESULTS SDPD accounted for 240 (22%) of 1114 poisoning deaths, the majority among men (n = 147, 61%). Increasing age, mental ill health (AOR 7.85, 95% CI: 5.46-11.28), chronic pain (AOR 5.57, 95% CI: 3.28-9.46), and history of previous overdose (AOR 5.06, 95% CI: 3.39-7.56) were associated with increased odds of SDPD, with similar results for both sexes. The main drugs associated with SDPD were non-opioid analgesics (OR 4.06 [95% CI 2.66-6.18]), antipsychotics (OR 2.42 [95% CI 1.63-3.60]) and antidepressants (OR 2.18 [95% CI 1.59-2.97]). Pregabalin was associated with SDPD among women only. LIMITATIONS Secondary analysis of coronial data on drug poisoning deaths therefore findings may not be relevant to suicide deaths in general. CONCLUSIONS Ongoing monitoring for signs of suicidal intent in individuals with mental illness, chronic pain, overdose, and/or prescribed mental health medications may identify individuals in need of additional intervention.

Abstract
BACKGROUND Several studies suggest suicidal motivation may contribute to opioid overdose fatalities in people with opioid use disorder. In this study, we sought to replicate and extend prior findings suggesting that a desire to die is common prior to nonfatal opioid overdose in people with opioid use disorder. METHODS Adults receiving inpatient detoxification and stabilization who reported a history of opioid overdose (N = 60) completed questions about suicidal cognition prior to their most recent overdose. RESULTS Approximately 45% reported some desire to die prior to their most recent overdose, with 20% reporting they had some intention to die. The correlation between these ratings was of a moderate magnitude (ρ = 0.58). Almost 40% of the sample perceived no risk of overdose prior to their most recent overdose event, suggesting a significant underestimation of risk in this population. CONCLUSIONS Desire to die was common in adults with opioid use disorder prior to nonfatal opioid overdose events, and 1 in 5 people with a history of opioid overdose reported intention to die prior to their most recent opioid overdose. Careful assessment of suicidal cognition in this population may improve prevention of opioid overdose deaths.

Front Psychiatry 2022; 13:883878.

Abstract
Objectives The objective of the study was to longitudinally assess the outcomes and correlates of suicidal ideation and behavior (SIB) among heroin users who attended inpatient detoxification and psychosocial rehabilitation. SIB was assessed in 300 heroin users upon entry into inpatient detoxification (baseline) as well as 3-months (t1) (n = 252; 84%) and 9-months (t2) (n = 225; 75%) post treatment. Multivariable logistic regression was used to determine the demographic, clinical and treatment related factors that increased the risk for a high SIB score. Results From baseline to t1 there was a significant decrease in the proportion of those who endorsed SIB (68.7 vs. 38.9%, p < 0.0001). There was an increase in the proportion of those who endorsed SIB from t1 to t2 (38,9 vs. 47.1%, p = 0.047). There was a significant increase in the proportion of those reporting suicide likely in the near future from baseline to t1 (8.7 vs. 16.3%: p < 0.0049) and this was repeated from t1 to t2 (22.7%) (t1 vs. t2: p = 0.031). After controlling for all other variables, a comorbid mental illness (MI) at baseline was a significant independent risk factor for a high SIB score at t1(RR 1.63; 95% CL 1.30-2.03) (p < 0.0001) and a comorbid MI at t1 increased the risk for a high SIB score at t2 (RR 2.73; 95% CL 1.78-4.19) (p < 0.0001). A poorer general health score and poorer social functioning score at baseline were associated with a high SIB score at baseline (RR 1.02; 95% CL 1.01-1.04) (p = 0.001) and t2, respectively (RR 1.07; 95% CL 1.04-1.11) (p < 0.0001). Conclusions Among heroin users, a comorbid mental illness, poorer physical health and poorer social functioning are important factors to consider in suicide risk assessment. Although there were decreases in overall SIB 3 months after detoxification, this trend was not sustained at 9-month follow-up. After detoxification there were significant increases in the proportion of those reporting a likelihood of suicide in the following 3 months. The results suggests that the treatment exposure did not adequately mitigate suicide risk. There is a need for review of the treatment as well as targeted screening and management of SIB in heroin users attending treatment services.

Abstract
Background: Profiles of individuals with cannabis-related disorders (CRD) in specialized addiction treatment centers serving high-need patients have not been identified. This longitudinal study developed a typology for 9,836 individuals with CRD attending Quebec (Canada) addiction treatment centers in 2012-2013. Methods: Data on sociodemographic, clinical and service use variables were extracted from several databases for the years 1996-1997 to 2014-2015. Individual profiles were produced using Latent Class Analysis and compared predicting health outcomes on emergency department (ED) use, hospitalizations and suicidal behaviors for 2015-2016. Results: Six profiles were identified: 1-Older individuals, many living in couples and working, with moderate health problems, receiving intensive general practitioner (GP) care and high continuity of physician care; 2-Older individuals with chronic CRD, multiple social and health problems, and low health service use (chronic CRD referred to experiencing CRD for several years; social problems related to homelessness, unemployment, having criminal records or living alone); 3-Students with few social and health problems, and low health service use; 4-Young adults, many working, with few health problems, least health service use and continuity of physician care; 5-Youth, many working but some criminal offenders, with 1 or 2 years of CRD, few health problems and high addiction treatment center use; and 6-Older individuals with chronic CRD and multiple social and health problems, high health service use and continuity of physician care. Profiles 6 and 2 had the worst health outcomes. Conclusions: For Profiles 2 to 5, outreach and motivational services should be prioritized, integrated health and criminal justice services for profile 5 and, for Profiles 2 and 6, assertive community treatments. Screening, brief intervention and referrals to addiction treatment centers may also be encouraged for individuals with CRD, particularly those in Profile 2. This cohort had high social and health needs relative to services received, suggesting continued need for care.

Abstract
Substance use disorders (SUDs) are important risk factors for suicide, yet little is known about how suicide risks vary by specific SUDs. We examined these risks for the first time in a large general population to facilitate comparisons across SUDs. A national cohort study was conducted of all 6,947,191 adults in Sweden. SUDs (opioid, sedative/hypnotic, hallucinogen, cannabis, amphetamine, cocaine, and alcohol use disorders) were identified using inpatient, outpatient, and crime data, and suicide deaths using nationwide death data with follow-up during 2003-2016. Cox regression was used to compute hazard ratios (HRs) for suicide death while adjusting for sociodemographic factors and psychiatric, SUD, and somatic comorbidities. Co-sibling analyses assessed for confounding by unmeasured shared familial (genetic and/or environmental) factors. In 79.8 million person-years of follow-up, 15,616 (0.2%) suicide deaths were identified. All SUDs were associated with significantly increased risks, with HRs ranging from 12- to 26-fold and 2.5- to 6.4-fold before and after adjusting for covariates, respectively. After adjusting for all covariates, opioid use disorder was the strongest risk factor (HR, 6.39; 95% CI, 5.53-7.38) (P ≤ 0.002 compared with any other SUD), followed by sedative/hypnotic use disorder (4.62; 4.06-5.27) (P ≤ 0.009 compared with any other SUD except opioid or hallucinogen). Most associations persisted after controlling for shared familial factors, consistent with causal effects. In this large national cohort, all SUDs were associated with significantly increased risks of suicide death, especially opioid and sedative/hypnotic use disorders. These findings may improve risk stratification and inform interventions to prevent suicide in the highest-risk subgroups with SUDs.

Abstract
This review aimed to identify and synthesize strategies and actions adopted by addiction facilities to support and maintain treatment during the coronavirus disease 2019 (COVID-19) pandemic. A scoping review was conducted using the following information sources: Virtual Health Library, SCOPUS, Web of Science, PubMed, CINAHL, and Latin American and Caribbean Health Science Literature. From a total of 971 articles, 28 studies were included. The strategies to maintain the care offer were telehealth/telemedicine, counselling/screening, 24-h telephone, webinars, conducting group therapy and support among users, adaptation for electronic health records, increased methadone/naloxone dispensing, restriction in the number of medication dispensing/day, and electronic prescription and home delivery medications. These strategies can be used to support health professionals in addressing the impact of the pandemic on the treatment of those in recovery or struggling with a substance use disorder when in-person treatment is not possible.

Abstract
Background and Objectives: Over the past twenty years a large number of new psychoactive substances (NPS) have entered and modified the recreational drug scene. Their intake has been associated with health-related risks, especially so for vulnerable populations such as people with severe mental illness, who might be at higher risk of suicidality or self-injurious behavior. This paper aims at providing an overview of NPS abuse and the effects on mental health and suicidality issues, by performing a literature review of the current related knowledge, thereby identifying those substances that, more than others, are linked to suicidal behaviors. Materials and Methods: A comprehensive and updated overview of the literature regarding suicidality and NPS categories has been undertaken. An electronic search was performed, including all papers published up to March 2021, using the following keywords “NPS” OR “new psychoactive substances” OR “novel psychoactive substances” OR “synthetic cannabinoids” OR “phenethylamines” OR “synthetic cathinones” OR “tryptamines” OR “piperazines” OR “new synthetic opioids” OR “designer benzodiazepines” AND (“suicide” OR “suicidality”) NOT review NOT animal on the PubMed, Cochrane Library, and Web of Science online databases. Results: Suicidality and self-injurious behavior appear to be frequently associated with some NPS such as cathinones, synthetic cannabinoids, and new synthetic opioids. The results are organized according to the substances recorded. Conclusion: The growing use of NPS has become a significant clinical issue, causing increasing concern and challenges for clinicians working in both mental health and emergency departments. Thus, considering the associations between NPS and suicidality or self-injurious behaviors, areas where suicide-prevention efforts and strategies might be focused are the early detection, monitoring, and restriction of NPS.

Abstract
Background: Research over the past several decades has shown an increased risk for completed suicide among people who use drugs (PWUD). However, no study to date has attempted to summarise the available literature on the variety of risk factors associated with this increased risk. This paper presents a protocol for a scoping review that aims to systematically map and synthesise the extent and nature of published, unpublished and grey literature related to risk factors for suicide among PWUD. Methods: The following six-stage methodological framework for scoping reviews proposed by Arksey and O’Malley with enhancements by Levac and colleagues will be used: (1) identifying the research question, (2) identifying relevant studies, (3) study selection, (4) charting/mapping the data, (5) collating, summarising and reporting results and (6) expert consultation. The review will be conducted and reported in accordance with the PRISMA Extension for Scoping Reviews (PRISMA-ScR). Key inclusion and exclusion criteria will be developed to guide literature screening and data charting. Three reviewers will conduct the initial screening of published, unpublished and grey literature. Identified risk factors will be collated, summarised and categorised iteratively by two independent reviewers. Stakeholder consultation will occur with experts from a national steering committee, a national advisory group, a national suicide prevention centre and a European drug monitoring centre. Conclusion: Collating and thematically categorising the various risk factors for suicide among this high-risk group will hold important implications for future research, policy and practice. The research will be disseminated through publication in a peer-reviewed academic journal and a conference presentation, and by sharing the findings with key stakeholders working within research, policy-making and professional practice contexts.

Abstract
In light of the recent changes in the legal status of cannabis in Canada, the understanding of the potential impact of the use of cannabis by individuals suffering from depression is increasingly considered as being important. It is fundamental that we look into the existing literature to examine the influence of cannabis on psychiatric conditions, including mood disorders. In this article, we will explore the relationship that exists between depression and cannabis. We will examine the impact of cannabis on the onset and course of depression, and its treatment. We have undertaken a wide-ranging review of the literature in order to address these questions. The evidence from longitudinal studies suggest that there is a bidirectional relationship between cannabis use and depression, such that cannabis use increases the risk for depression and vice-versa. This risk is possibly higher in heavy users having initiated their consumption in early adolescence. Clinical evidence also suggests that cannabis use is associated with a worse prognosis in individuals with major depressive disorder. The link with suicide remains controversial. Moreover, there is insufficient data to determine the impact of cannabis use on cognition in individuals with major depression disorder. Preliminary evidence suggesting that the endogenous cannabinoid system is involved in the pathophysiology of depression. This will need to be confirmed in future positron emission tomography studies. Randomized controlled trials are needed to investigate the potential efficacy of motivational interviewing and/or cognitive behavioral therapy for the treatment of cannabis use disorder in individuals with major depressive major disorder. Finally, although there is preclinical evidence suggesting that cannabidiol has antidepressant properties, randomized controlled trials will need to properly investigate this possibility in humans.

Prevalence, sociodemographic variables, mental health condition, and type of drug use associated with suicide behaviors among people with substance use disorders: a systematic review and meta-analysis.

Abstract
We assessed the prevalence, sociodemographic variables, mental health condition, and type of drug use associated with suicide behaviors among patients with substance use disorders (SUD). Studies in English published from January 1, 1995 to December 31, 2020 were searched on PubMed, Scopus, Cochrane and Web of Science to identify studies on variables associated with suicidal behaviors (ideations and attempts) among patients with SUD. After reviewing for study duplicates, the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes (PICO) criteria: (i) population: patients with SUD; (ii) intervention: suicide behaviors in the past year; (iii) comparator: SUD who had not suicide behaviors; (iv) outcome: suicide ideations or attempts in the last year; and (v) study type: cross-sectional, cohort, and case-control studies. Out of 10,810 articles, 48 studies met eligibility criteria. Our findings showed a pooled prevalence rate of suicide ideations of 35% (95% CI, 22% 48%) and suicide attempts of 20% (95% CI, 17% 23%) in the last year among patients with SUD. Smoking, previous history of sexual abuse, depression, and alcohol and cannabis use disorders were significantly associated with suicide ideations. Study findings also showed that being female, smoking, history of physical and sexual abuse, depression and alcohol, cannabis, cocaine, amphetamine use disorders, and polysubstance abuse were significantly associated with suicide attempts among patients with SUD. These findings have implications for developing prevention programs. Appropriate initiatives for reducing the risk of suicide behaviors like systematic assessments of changes in drug use pattern at the emergency departments or at other key health providers may be more broadly implemented. Motivational therapy to improve help-seeking, increased information on adverse consequences of heavy substance use, and crisis plan resolutions to face suicide behaviors could also be consolidated.

Psychiatry Res 2021; 296:113639.

Abstract
Cohort study. This follow-up study (from 1975 to 2016) was aimed to estimate the mortality risk for suicide in a cohort of patients presenting to a public treatment centre for addiction (SERD) with Alcohol Use Disorder (AUD), Heroin Use Disorder - HUD or Cocaine Use Disorder (CUD), also relating to their access to a Mental Heath Service. Crude Mortality Rates for suicide were higher for patients with AUDs, for men and subjects 45-64 years old. Hanging was the main cause of suicide death. We highlight an increase in mortality in the period 2009-2012, which coincides with the economic recession, and in the year of first contact with a SERD. The Standardized Mortality Ratios (SMRs) were 4.9, higher among females than males. From the multivariate analysis, a higher risk for patients that were separated or divorced was observed. The results of our study provide some guidance on the features of subjects at greatest risk of death from suicide, which may be useful in reducing and preventing suicide and gaining a better clinical management of patients with SUDs.
