Excess Fatal Overdoses in the United States During the COVID-19 Pandemic by Geography and Substance Type: March 2020-August 2021.

Objectives. To assess heterogeneity in pandemic-period excess fatal overdoses in the United States, by location (state, county) and substance type. Methods. We used seasonal autoregressive integrated moving average (SARIMA) models to estimate counterfactual death counts in the scenario that no pandemic had occurred. Such estimates were subtracted from actual death counts to assess the magnitude of pandemic-period excess mortality between March 2020 and August 2021. Results. Nationwide, we estimated 25 668 (95% prediction interval [PI] = 2811, 48 524) excess overdose deaths. Specifically, 17 of 47 states and 197 of 592 counties analyzed had statistically significant excess overdose-related mortality. West Virginia, Louisiana, Tennessee, Kentucky, and New Mexico had the highest rates (20-37 per 100 000). Nationally, there were 5.7 (95% PI = 1.0, 10.4), 3.1 (95% PI = 2.1, 4.2), and 1.4 (95% PI = 0.5, 2.4) excess deaths per 100 000 involving synthetic opioids, psychostimulants, and alcohol, respectively. Conclusions. The steep increase in overdose-related mortality affected primarily the southern and western United States. We identified synthetic opioids and psychostimulants as the main contributors. Public Health Implications. Characterizing overdose-related excess mortality across locations and substance types is critical for optimal allocation of public health resources.

Racial and Ethnic Disparities in All-Cause and Cause-Specific Mortality Among US Youth.

Importance: Mortality rates in US youth have increased in recent years. An understanding of the role of racial and ethnic disparities in these increases is lacking. Objective: To compare all-cause and cause-specific mortality trends and rates among youth with Hispanic ethnicity and non-Hispanic American Indian or Alaska Native, Asian or Pacific Islander, Black, and White race. Design, Setting, and Participants: This cross-sectional study conducted temporal analysis (1999-2020) and comparison of aggregate mortality rates (2016-2020) for youth aged 1 to 19 years using US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database. Data were analyzed from June 30, 2023, to January 17, 2024. Main Outcomes and Measures: Pooled, all-cause, and cause-specific mortality rates per 100 000 youth (hereinafter, per 100 000) for leading underlying causes of death were compared. Injuries were classified by mechanism and intent. Results: Between 1999 and 2020, there were 491 680 deaths among US youth, including 8894 (1.8%) American Indian or Alaska Native, 14 507 (3.0%) Asian or Pacific Islander, 110 154 (22.4%) Black, 89 251 (18.2%) Hispanic, and 267 452 (54.4%) White youth. Between 2016 and 2020, pooled all-cause mortality rates were 48.79 per 100 000 (95% CI, 46.58-51.00) in American Indian or Alaska Native youth, 15.25 per 100 000 (95% CI, 14.75-15.76) in Asian or Pacific Islander youth, 42.33 per 100 000 (95% CI, 41.81-42.86) in Black youth, 21.48 per 100 000 (95% CI, 21.19-21.77) in Hispanic youth, and 24.07 per 100 000 (95% CI, 23.86-24.28) in White youth. All-cause mortality ratios compared with White youth were 2.03 (95% CI, 1.93-2.12) among American Indian or Alaska Native youth, 0.63 (95% CI, 0.61-0.66) among Asian or Pacific Islander youth, 1.76 (95% CI, 1.73-1.79) among Black youth, and 0.89 (95% CI, 0.88-0.91) among Hispanic youth. From 2016 to 2020, the homicide rate in Black youth was 12.81 (95% CI, 12.52-13.10) per 100 000, which was 10.20 (95% CI, 9.75-10.66) times that of White youth. The suicide rate for American Indian or Alaska Native youth was 11.37 (95% CI, 10.30-12.43) per 100 000, which was 2.60 (95% CI, 2.35-2.86) times that of White youth. The firearm mortality rate for Black youth was 12.88 (95% CI, 12.59-13.17) per 100 000, which was 4.14 (95% CI, 4.00-4.28) times that of White youth. American Indian or Alaska Native youth had a firearm mortality rate of 6.67 (95% CI, 5.85-7.49) per 100 000, which was 2.14 (95% CI, 1.88- 2.43) times that of White youth. Black youth had an asthma mortality rate of 1.10 (95% CI, 1.01-1.18) per 100 000, which was 7.80 (95% CI, 6.78-8.99) times that of White youth. Conclusions and Relevance: In this study, racial and ethnic disparities were observed for almost all leading causes of injury and disease that were associated with recent increases in youth mortality rates. Addressing the increasing disparities affecting American Indian or Alaska Native and Black youth will require efforts to prevent homicide and suicide, especially those events involving firearms.

Improving state medicolegal death investigation: Does system level reform improve public health data concerning drug-related mortality?

In the United States, the governance of unnatural death certification varies greatly by state. Although cross-sectional research has linked mortality data quality with variation in medicolegal death investigation systems across states-especially with regards to drug-related deaths-this relationship has not be sufficiently tested using longitudinal data. This research assesses the impact of system governance reform on the quality of drug mortality data by assessing the impact of transitioning from a coroner system to a medical examiner system on data quality. The research finds no evidence that system-level reform is associated with improved drug-related mortality data quality. These findings suggest that alternative methods should be examined for improving public health data concerning drug-related mortality. These likely include focusing on individual-level characteristics and practices of officials and offices, rather than system-level variables.

Mortality Among Users of Anabolic Steroids.

This cohort study investigates mortality and cause of death among a large cohort of androgenic anabolic steroid users, compared with a control group, in Denmark from January 3, 2006, to March 1, 2018.

Elevated drug overdose mortality among Americans who visit Florida, 2003-2020.

OBJECTIVE: Florida state has played a conspicuous role in the current U.S. drug epidemic. Reports suggest that even non-Florida residents may suffer excessive overdose fatalities while visiting the state, possibly in connection to two sets of events: (1) the overprescribing of controlled substances, and more recently, (2) the exploitation of patients' insurance benefits by unscrupulous operators of substance use treatment facilities in Florida. To date, however, no research has examined the overdose fatalities of non-Florida residents inside Florida. METHODS: Death certificate data were used to calculate proportionate mortality ratios for overdoses among Florida residents and visitors. Deaths occurring in the rest of the USA were used as reference populations. RESULTS: Between 2003 and 2020, overdose mortality was slightly elevated for Florida residents within their home counties (106.7 (95% CI 105.8 to 107.5)) and in other Florida counties (113.0 (95% CI 110.0 to 116.0)). Significantly, this mortality was much higher among out-of-state visitors in Florida (163.1 (95% CI 157.5 to 168.8)). When analysed by year, greater overdose mortality among visitors coincided with years when drug prescribing in Florida was rampant, and with the advent of expanded insurance coverage for substance use treatment. During this more recent period (since 2014), overdose mortality was exceptionally high for out-of-state visitors in Palm Beach County, where reports of malpractice in the Florida treatment industry have been concentrated. CONCLUSIONS: Overdose mortality was disproportionately high among out-of-state visitors in Florida. The results suggest that the regulatory policies in Florida may be implicated in drug-related casualties of people who live in other parts of the USA.

Responding to 'wicked problems': policy and governance on drug-related deaths in English and Welsh prisons, 2015-2021.

BACKGROUND: Prison settings have been neglected in the growing literature on drug-related deaths. This paper explores policy and practice issues regarding the governance of drug-related deaths in prisons in England and Wales from 2015-2021. METHODS: Thematic documentary analysis was conducted on national level policy documents published between 2015-2021 (e.g. drug strategies, prison policy documents, Her Majesty's Inspectorate of Prisons and Prison and Probation Ombudsman (PPO) annual reports and guidance for staff). At the local (prison) level, all of the PPO fatal investigation reports and their associated action plans relating to 171 drug-related deaths from 2015-2021 were analysed thematically. Various modes of governance were identified using Head's 'wicked problems' conceptual framework including avoidance and denial, coercive controls, compartmentalised micro-management, incremental and pragmatic adjustment and technocratic problem-solving. RESULTS: There was strong evidence of the dominance of denial of the problem of drug-related deaths, coercive controls, micro-management and reliance on technological solutions in the early years (2015-2018). In some prisons, there developed a move towards the adoption of more pragmatic and incremental policies and push towards comprehensive policies over time. In others, remnants of denial and coercion remained. In our analysis, the focus on new psychoactive substances came to dominate attention, to the relative neglect of other substances and of the contribution of mental and physical illness to these deaths. Staff are not equipped, supported or resourced adequately to deal with the two 'wicked problems' of increasing rates of drug use and mental illness which collide in the prison setting. CONCLUSION: The PPO investigations repeatedly recommend reducing supply and improving monitoring and surveillance and the emergency response. There is less focus on prevention and reducing demand or improving the wider environmental context and culture in which the deaths occur. Policy needs to pay more attention to the fundamental issues driving the current deterioration in conditions in prisons.

Fire deaths in Cape Town, South Africa: A retrospective review of medico-legal and toxicological findings (2006 - 2018).

BACKGROUND: In South Africa, fire-related deaths are common, particularly within dense informal housing settlements. Published data on deaths from fire incidents in Cape Town is sparse. Additionally, little emphasis has been placed on the role of toxicological investigations in these deaths, despite the known risk of alcohol and drug impairment to burn injury. METHODS: A retrospective, descriptive analysis of post-mortem case reports from Salt River Mortuary was conducted to investigate all deaths in which fires were involved in the west metropole of Cape Town, between 2006 to 2018. Demographic, circumstantial, and toxicological data were analyzed using R software. RESULTS: In total 1370 fire deaths occurred over 13 years, with a mean of 106 (SD ± 18) cases per annum (≈3% of the annual caseload and a mortality rate of 5.5 per 100,000). Males (70.4%), adults (mean=30.7 years), and toddlers (1-4 years old) were notably at risk. Deaths typically occurred in the early morning (00h00 - 06h00) (45.7%), during winter (32.1%), and in lower socioeconomic areas with highly dense informal settlements (65.6%), with 29% of deaths occurring in multi-fatality incidents. Ethanol was detected (≥0.01 g/100 mL) in 55.1% of cases submitted for analysis (71.5%), with a mean of 0.18 g/100 mL, and with 93.8% of positive cases > 0.05 g/100 mL. Carboxyhaemoglobin (COHb) analysis was requested in 76.4% of cases, with 57% of cases having a %COHb of ≥ 20%. Toxicology results (for drugs other than ethanol) from the national laboratory were outstanding in 34.4% of the cases at the conclusion of the study. BAC and %COHb were significantly higher in deaths from burns and smoke inhalation (usually accidents) than deaths from combined trauma and burns (typically homicides). Fire deaths with high COHb levels were more likely to display cherry-red discoloration (OR=3.1) and soot in the airways (OR=2.7) at autopsy. CONCLUSION: This article provides an updated description of fire deaths in the west metropole of Cape Town. The importance of BAC and COHb testing in these cases was noted, and the authors call for an investigation of the role of drug impairment (specifically frequently misused drugs methamphetamine and methaqualone) as a risk factor in these deaths. Areas of high-density informal settlements, where open flames are used to heat, light, and cook, were noted as high risk.

Temporal Trends in Substance Use and Cardiovascular Disease-Related Mortality in the United States.

BACKGROUND: There are limited data on substance use (SU) and cardiovascular disease (CVD)-related mortality trends in the United States. We aimed to evaluate SU+CVD-related deaths in the United States using the Centers for Disease Control and Prevention Wide-Ranging, Online Data for Epidemiologic Research database. METHODS AND RESULTS: The Multiple Cause-of-Death Public Use record death certificates were used to identify deaths related to both SU and CVD. Crude, age-adjusted mortality rates, annual percent change, and average annual percent changes with a 95% CI were analyzed. Between 1999 and 2019, there were 636 572 SU+CVD-related deaths (75.6% men, 70.6% non-Hispanic White individuals, 65% related to alcohol). Age-adjusted mortality rates per 100 000 population were pronounced in men (22.5 [95% CI, 22.6-22.6]), American Indian or Alaska Native individuals (37.7 [95% CI, 37.0-38.4]), nonmetropolitan/rural areas (15.2 [95% CI, 15.1-15.3]), and alcohol-related death (9.09 [95% CI, 9.07 to 9.12]). The overall SU+CVD-related age-adjusted mortality rates increased from 9.9 (95% CI, 9.8-10.1) in 1999 to 21.4 (95% CI, 21.2-21.6) in 2019 with an average annual percent change of 4.0 (95% CI, 3.7-4.3). Increases in SU+CVD-related average annual percent change were noted across all subgroups and were pronounced among women (4.8% [95% CI, 4.5-5.1]), American Indian or Alaska Native individuals, younger individuals, nonmetropolitan areas, and cannabis and psychostimulant users. CONCLUSIONS: There was a prominent increase in SU+CVD-related mortality in the United States between 1999 and 2019. Women, non-Hispanic American Indian or Alaska Native individuals, younger individuals, nonmetropolitan area residents, and users of cannabis and psychostimulants had pronounced increases in SU+CVD mortality.

Bayesian spatial analysis of age differences and geographical variations in illicit-drug-related mortality in the Islamic Republic of Iran.

Background: Drug use disorders are significant social and public health concerns in the Islamic Republic of Iran; however, little is known about drug-related mortality. Aims: We quantified the spatial and age distribution of direct illicit-drug-related mortality in the Islamic Republic of Iran, to inform harm reduction policies and interventions. Methods: We modelled and mapped registered illicit-drug-related deaths from March 2016 to March 2017. Data were obtained from the Iranian Forensic Medicine Organization. Besag-York-Mollie models were fitted using Bayesian spatial analysis to estimate the relative risk of illicit-drug-related mortality across different provinces and age groups. Results: There were 2203 registered illicit-drug-related deaths during the study period, 1289 (58.5%) occurred in people aged 20-39 years and among men (n = 2013; 91.4%). The overall relative risk (95% credible interval) of illicit-drug-related mortality in the provinces of Hamadan (3.37; 2.88-3.91), Kermanshah (1.90; 1.55-2.28), Tehran (1.80; 1.67-1.94), Lorestan (1.71; 1.37-2.09), Isfahan (1.40; 1.21-1.60), and Razavi Khorasan (1.18; 1.04-1.33) was significantly higher than in the rest of the country. Conclusion: We found evidence of age differences and spatial variations in illicit-drug-related mortality across different provinces in the Islamic Republic of Iran. Our findings highlight the urgent need to revisit existing drug-use treatment and harm reduction policies and ensure that overdose prevention programmes are adequately available for different age groups and settings.

Invited Commentary: Stop Analyzing Suicides, Drug-Related Deaths, and Alcohol-Related Deaths Together.

In the accompanying article, Spark et al. (Am J Epidemiol. 2023;192(5):720-731) estimate the undercounting of deaths due to suicide, drug use, and alcohol use in a Colorado veteran population and argue for a standardized case definition for the 3 causes of mortality. Use of a case definition for these 3 causes of death combined implies that they should be analyzed together. This is problematic, given the disparate trends in and historical contexts behind these 3 different causes of death.

Profiles of quality of outpatient care use, associated sociodemographic and clinical characteristics, and adverse outcomes among patients with substance-related disorders.

BACKGROUND: This study identified patient profiles in terms of their quality of outpatient care use, associated sociodemographic and clinical characteristics, and adverse outcomes based on frequent emergency department (ED) use, hospitalization, and death from medical causes. METHODS: A cohort of 18,215 patients with substance-related disorders (SRD) recruited in addiction treatment centers was investigated using Quebec (Canada) health administrative databases. A latent class analysis was produced, identifying three profiles of quality of outpatient care use, while multinomial and logistic regressions tested associations with patient characteristics and adverse outcomes, respectively. RESULTS: Profile 1 patients (47% of the sample), labeled "Low outpatient service users", received low quality of care. They were mainly younger, materially and socially deprived men, some with a criminal history. They had more recent SRD, mainly polysubstance, and less mental disorders (MD) and chronic physical illnesses than other Profiles. Profile 2 patients (36%), labeled "Moderate outpatient service users", received high continuity and intensity of care by general practitioners (GP), while the diversity and regularity in their overall quality of outpatient service was moderate. Compared with Profile 1, they  were older, less likely to be unemployed or to live in semi-urban areas, and most had common MD and chronic physical illnesses. Profile 3 patients (17%), labeled "High outpatient service users", received more intensive psychiatric care and higher quality of outpatient care than other Profiles. Most Profile 3 patients lived alone or were single parents, and fewer lived in rural areas or had a history of homelessness, versus Profile 1 patients. They were strongly affected by MD, mostly serious MD and personality disorders. Compared with Profile 1, Profile 3 had more frequent ED use and hospitalizations, followed by Profile 2. No differences in death rates emerged among the profiles. CONCLUSIONS: Frequent ED use and hospitalization were strongly related to patient clinical and sociodemographic profiles, and the quality of outpatient services received to the severity of their conditions. Outreach strategies more responsive to patient needs may include motivational interventions and prevention of risky behaviors for Profile 1 patients, collaborative GP-psychiatrist care for Profile 2 patients, and GP care and intensive specialized treatment for Profile 3 patients.

Deaths of Despair and Population Aging in Missouri.

Recent declines in life expectancy in the US, especially for middle-aged White persons, have called attention to mortality from deaths of despair - deaths due to alcohol, drugs, and suicide. Using data from the Centers for Disease Control and the U.S. Census Bureau, this paper examined deaths of despair by race/ethnicity, age, cause of death, birth cohort, and sex in Missouri. We focused on Area Agencies on Aging as geographic units of interest to increase usefulness of our findings to public administrators. Deaths of despair began trending up for all age groups beginning in 2007-2009, with the sharpest increases occurring for Black or African American non-Hispanics beginning in 2013-2015. The most dramatic increases occurred for the population age 50-59 in St. Louis City and Area Agency on Aging regions in southern Missouri. For older adults, considerable variation in rates, trends, and cause of deaths of despair is evident across the state.

Contributors to Early Mortality in African Americans, the Jackson Heart Study.

Introduction: In recent years, premature "deaths of despair" (ie, due to alcohol, drug use, and suicide) among middle-aged White Americans have received increased attention in the popular press, yet there has been less discussion on what explains premature deaths among young African Americans. In this study, we examined factors related to deaths of despair (alcohol use, drug use, smoking) and contextual factors (perceived discrimination, socioeconomic status, neighborhood conditions) as predictors of premature deaths before the age of 65 years among African Americans. Methods: The Jackson Heart Study (JHS) is a longitudinal cohort study of African Americans in the Jackson, Mississippi, metropolitan statistical area. We included participants younger than 65 years at baseline (n=4000). Participant enrollment began in 2000 and data for these analyses were collected through 2019. To examine predictors of mortality, we calculated multivariable adjusted hazard ratios (HRs; 95% CI), using Cox proportional hazard models adjusted for age, sex, ideal cardiovascular health metrics, drug use, alcohol intake, functional status, cancer, chronic kidney disease, asthma, waist circumference, depression, income, education, health insurance status, perceived neighborhood safety, and exposure to lifetime discrimination. Results: There were 230 deaths in our cohort, which spanned from 2001-2019. After adjusting for all covariates, males (HR, 1.50; 95% CI, 1.11-2.03), participants who used drugs (HR, 1.53; 95% CI, 1.13-2.08), had a heavy alcohol drinking episode (HR, 1.71; 95% CI, 1.22-2.41), reported 0-1 ideal cardiovascular health metrics (HR, 1.78; 95% CI, 1.06-3.02), had cancer (HR, 2.38; 95% CI, 1.41-4.01), had poor functional status (HR, 1.68; 95% CI, 1.19-2.37), or with annual family income less than $25,000 (HR, 1.63; 95% CI, 1.02-2.62) were more likely to die before 65 years of age. Conclusions: In our large cohort of African American men and women, clinical predictors of premature death included poor cardiovascular health and cancer, and social predictors included low income, drug use, heavy alcohol use, and being a current smoker. Clinical and social interventions are warranted to prevent premature mortality in African Americans.

Urban-Rural Disparities in Deaths of Despair: A County-Level Analysis 2004-2016 in the U.S.

Introduction: The purpose of this study is to examine nationwide disparities in drug, alcohol, and suicide mortality; evaluate the association between county-level characteristics and these mortality rates; and illustrate spatial patterns of mortality risk to identify areas with elevated risk. Methods: The authors applied a Bayesian spatial regression technique to investigate the association between U.S. county-level characteristics and drug, alcohol, and suicide mortality rates for 2004-2016, accounting for spatial correlation that occurs among counties. Results: Mortality risks from drug, alcohol, and suicide were positively associated with the degree of rurality, the proportion of vacant housing units, the population with a disability, the unemployed population, the population with low access to grocery stores, and the population with no health insurance. Conversely, risks were negatively associated with Hispanic population, non-Hispanic Black population, and population with a bachelor's degree or higher. Conclusions: Spatial disparities in drug, alcohol, and suicide mortality exist at the county level across the U.S. social determinants of health; educational attainment, degree of rurality, ethnicity, disability, unemployment, and health insurance status are important factors associated with these mortality rates. A comprehensive strategy that includes downstream interventions providing equitable access to healthcare services and upstream efforts in addressing socioeconomic conditions is warranted to effectively reduce these mortality burdens.

Body Packer y Body Stuffer: Serie de Casos. Revisión / Body Packer y Body Stuffer: serie de casos. Revision

"Body packing", "Body pushing" y "Body stuffing" son distintas formas de transportar sustancias ilegales dentro del cuerpo humano. Frente al ingreso en la unidad de emergencias de un "Body Packer", conocido como "tragador de paquetes" con fines de contrabando o un "Body Stuffer" llamados "tragadores rápidos", quienes ingieren en forma compulsiva paquetes manufacturados para la venta de sustancias ante la posibilidad de ser sorprendidos por agentes de la ley; se plantean una serie de desafíos en cuanto al tratamiento que al día de hoy permanecen en debate. Generalmente se prefiere mantener una conducta conservadora facilitando la expulsión de los paquetes. En aquellos casos en los que los pacientes presenten paquetes atascados o rotos o no mejoren con el tratamiento conservador, se recomienda el tratamiento quirúrgico.El presente trabajo tiene por objetivo reportar una serie de casos internados por ingesta de paquetes potencialmente peligrosos que se sometieron a una evacuación farmacológica y/o quirúrgica en 8 pacientes y una revisión bibliográfica sobre el tema.

"Body packing", "Body pushing", and "Body stuffing" are different ways to use the interior of the human body to transport illegal substances. In the face of a "Body Packer" or a "Body Stuffer" known as "fast swallowers", which are those cases in which they compulsively swallow manufactured packages for the sale of substances before the possibility of being surprised by law enforcement officers, a series of challenges present themselves regarding the treatment, which is currently up for debate. Generally, a conservative conduct is preferred, facilitating the expulsion of the packages. In those cases, in which patients have stuck or broken packages or do not improve with conservative treatment, surgical treatment is recommended.The present paper aims to report a series of cases in which the patients were admitted due to an intake of potentially dangerous packages and put through a pharmacological evacuation and/or surgical evacuation of 8 patients, and a bibliographical revision on the subject.

Drug Overdose Mortality Among People Experiencing Homelessness, 2003 to 2018.

Importance: Despite high rates of drug overdose death among people experiencing homelessness, patterns in drug overdose mortality, including the types of drugs implicated in overdose deaths, remain understudied in this population. Objective: To describe the patterns in drug overdose mortality among a large cohort of people experiencing homelessness in Boston vs the general adult population of Massachusetts and to evaluate the types of drugs implicated in overdose deaths over a continuous 16-year period of observation. Design, Setting, and Participants: This cohort study analyzed adults aged 18 years or older who received care at Boston Health Care for the Homeless Program (BHCHP) between January 1, 2003, and December 31, 2017. Individuals were followed up from the date of their initial BHCHP encounter during the study period until the date of death or December 31, 2018. Data were analyzed from December 1, 2020, to June 6, 2021. Main Outcomes and Measures: Drug overdose deaths and the types of drugs involved in each overdose death were ascertained by linking the BHCHP cohort to the Massachusetts Department of Public Health death records. Results: In this cohort of 60 092 adults experiencing homelessness (mean [SD] age at entry, 40.4 [13.1] years; 38 084 men [63.4%]), 7130 individuals died by the end of the study period. A total of 1727 individuals (24.2%) died of a drug overdose. Of the drug overdose decedents, 456 were female (26.4%), 194 were Black (11.2%), 202 were Latinx (11.7%), and 1185 were White (68.6%) individuals, and the mean (SD) age at death was 43.7 (10.8) years. The age- and sex-standardized drug overdose mortality rate in the BHCHP cohort was 278.9 (95% CI, 266.1-292.3) deaths per 100 000 person-years, which was 12 times higher than the Massachusetts adult population. Opioids were involved in 91.0% of all drug overdose deaths. Between 2013 and 2018, the synthetic opioid mortality rate increased from 21.6 to 327.0 deaths per 100 000 person-years. Between 2004 and 2018, the opioid-only overdose mortality rate decreased from 117.2 to 102.4 deaths per 100 000 person-years, whereas the opioid-involved polysubstance mortality rate increased from 44.0 to 237.8 deaths per 100 000 person-years. Among opioid-involved polysubstance overdose deaths, cocaine-plus-opioid was the most common substance combination implicated throughout the study period, with Black individuals having the highest proportion of cocaine-plus-opioid involvement in death (0.72 vs 0.62 in Latinx and 0.53 in White individuals; P < .001). Conclusions and Relevance: In this cohort study of people experiencing homelessness, drug overdose accounted for 1 in 4 deaths, with synthetic opioid and polysubstance involvement becoming predominant contributors to mortality in recent years. These findings emphasize the importance of increasing access to evidence-based opioid overdose prevention strategies and opioid use disorder treatment among people experiencing homelessness, while highlighting the need to address both intentional and unintentional polysubstance use in this population.

Positive Urine Drug Screens and External Mortality in Teenagers Who Present for Medical Care.

Objective: To examine whether a positive urine drug of abuse screen in youth who receive medical care is associated with subsequent risk of external mortality (eg, overdose, suicide, homicide, accident).Methods: This was a population-based retrospective cohort study of all Olmsted County (Minnesota) residents who were 13-18 years of age at the time of urine drug screen (UDS) testing (January 1, 1999, to November 28, 2012). Cox regression models were used to examine the relationships between having a positive UDS and external mortality, adjusted for sex, race, age, alcohol exposure, psychiatric diagnoses as defined by the International Classification of Diseases (ICD-9/ICD-10), and medical setting of UDS testing. Separate analyses were done for (1) overall UDS results, (2) tetrahydrocannabinol (THC), and (3) cocaine.Results: Of the 2,772 teenagers included in this study (47.2% male), a total of 26 died of external causes during a median follow-up period of 11.8 years. Testing positive for any illicit substance was not associated with significantly increased risk of external mortality (hazard ratio [HR] = 1.9; 95% CI, 0.9-4.2). Testing positive for cocaine was associated with significantly increased risk of external mortality (HR = 7.0; 95% CI, 1.9-25.0). Testing positive for THC was associated with a marginally significantly increased risk of external mortality (HR = 2.1; 95% CI, 1.0-4.7); however, when cocaine was added as a covariate in the analysis, the relationship between THC-positive UDS and mortality was still elevated but was no longer statistically significant (HR = 1.8; 95% CI, 0.8-4.1).Conclusions: History of cocaine-positive UDS may help identify a population of young people who are at high risk of premature death.

Pregnancy-Associated Deaths Due to Drugs, Suicide, and Homicide in the United States, 2010-2019.

OBJECTIVE: To estimate the prevalence of pregnancy-associated deaths due to drugs, suicide, and homicide nationwide from 2010 to 2019. METHODS: Using U.S. death certificate records from 2010 to 2019 for 33 states plus the District of Columbia, we identified pregnancy-associated deaths using the pregnancy checkbox and International Classification of Diseases, Tenth Revision codes, calculated pregnancy-associated death ratios, and categorized deaths by cause, timing relative to pregnancy, race or ethnicity, and age. RESULTS: Of 11,782 pregnancy-associated deaths identified between 2010 and 2019, 11.4% were due to drugs, 5.4% were due to suicide, and 5.4% were due to homicide, whereas 59.3% were due to obstetric causes and the remaining 18.5% were due to other causes. Drug-related deaths, suicide, and homicide accounted for 22.2% of pregnancy-associated deaths. All three causes of death increased over the study period, with drug-related pregnancy-associated deaths increasing 190%. Homicide during pregnancy and drug-related deaths, suicides, and homicide in the late postpartum period (43-365 days) accounted for a larger proportion of all deaths in these time periods than the contribution of these causes to all deaths among females of reproductive age. Pregnant and postpartum people identified as non-Hispanic American Indian or Alaska Native were at highest risk of drug-related and suicide death, and people identified as non-Hispanic Black were at highest risk of homicide. CONCLUSION: Deaths due to drug use, suicide, and homicide constitute more than one fifth of all deaths during pregnancy and the first year postpartum. Drug-related deaths and homicides have increased over the past decade. Substantial racial and ethnic inequities in these deaths exist.
