Assessing experts’ perspectives on challenges in substance misuse prevention, harm reduction, and treatment to shape funding priorities in New York State

BackgroundDrug overdose is a leading cause of death and opioid-related deaths increased by more than 300% from 2010 to 2020 in New York State. Experts holding a range of senior leadership positions from across New York State were asked to identify the greatest challenges in substance misuse prevention, harm reduction, and treatment continuum of care. Expert input was used to shape funding priorities.MethodIndividual semi-structured interviews of sixteen experts were conducted in April and May 2023. Experts included academics, medical directors, leaders of substance misuse service agencies, administrators of a state agency, a county mental health commissioner, the president of a pharmacy chain, and a senior vice president of an addiction-related national non-profit. Zoom interviews were conducted individually by an experienced qualitative interviewer and were recorded, transcribed, and coded for content. An initial report, with the results of the interviews organized by thematic content, was reviewed by the research team and emailed to the expert interviewees for feedback.ResultsThe research team identified five major themes: 1. Siloed and fragmented care delivery systems; 2. Need for a skilled workforce; 3. Attitudes towards addiction (stigma); 4. Limitations in treatment access; and 5. Social and drug related environmental factors. Most experts identified challenges in each major theme; over three-quarters identified issues related to siloed and fragmented systems and the need for a skilled workforce. Each expert mentioned more than one theme, three experts mentioned all five themes and six experts mentioned four themes.ConclusionsResearch, educational, and programmatic agendas should focus on identified topics as a means of improving the lives of patients at risk for or suffering from substance use-related disorders. The results of this project informed funding of pilot interventions designed to address the identified care challenges.

Foster Care and Health in Medicaid-Enrolled Children Experiencing Parental Opioid Use Disorder

The burden of the US opioid crisis has fallen heavily on children, a vulnerable population increasingly exposed to parental opioid use disorder (POUD) in utero or during childhood. A paucity of studies have investigated foster care involvement among those experiencing parental opioid use during childhood and the associated health and health care outcomes. To examine the health and health care outcomes of children experiencing POUD with and without foster care involvement. This population-based cohort study used nationwide Medicaid claims data from January 1, 2014, to December 31, 2020. Participants included Medicaid-enrolled children experiencing parental opioid use-related disorder during ages 4 to 18 years. Data were analyzed between January 2023 and February 2024. Person-years with (exposed) and without (nonexposed) foster care involvement, identified using Medicaid eligibility, procedure, and diagnostic codes. The main outcomes included physical and mental health conditions, developmental disorders, substance use, and health care utilization. The Pearson χ2 test, the t test, and linear regression were used to compare outcomes in person-years with (exposed) and without (nonexposed) foster care involvement. An event study design was used to examine health care utilization patterns before and after foster care involvement. In a longitudinal sample of 8 939 666 person-years from 1 985 180 Medicaid-enrolled children, 49% of children were females and 51% were males. Their mean (SD) age was 10 (4.2) years. The prevalence of foster care involvement was 3% (276 456 person-years), increasing from 1.5% in 2014 to 4.7% in 2020. Compared with those without foster care involvement (8 663 210 person-years), foster care involvement was associated with a higher prevalence of developmental delays (12% vs 7%), depression (10% vs 4%), trauma and stress (35% vs 7%), and substance use-related disorders (4% vs 1%; P < .001 for all). Foster children had higher rates of health care utilization across a wide array of preventive services, including well-child visits (64% vs 44%) and immunizations (41% vs 31%; P < .001 for all). Health care utilization increased sharply in the first year entering foster care but decreased as children exited care. In this cohort study of Medicaid-enrolled children experiencing parental opioid use-related disorder, foster care involvement increased significantly between 2014 and 2020. Involvement was associated with increased rates of adverse health outcomes and health care utilization. These findings underscore the importance of policies that support children and families affected by opioid use disorder, as well as the systems that serve them.

Transgender people in clinical trials of drugs and biologics: An analysis of ClinicalTrials.gov from 2007 to 2023.

Transgender people have unmet health needs related to chronic conditions such as dementia, osteoporosis and hypertension. Community-driven advocacy increased transgender representation in phase III trials for pharmacological prevention of HIV, but the extent to which drug trials for other conditions have included transgender people is unknown. We investigated the extent to which trials of drugs and biologics represented transgender people across therapeutic areas on ClinicalTrials.gov. Cross-sectional analysis of trials of drugs and biologics registered on ClinicalTrials.gov from 2007-2023. We included efficacy and effectiveness trials (phase II-IV) with transgender-related terms (e.g. 'transgend*'). We labelled trials as Inclusive or Exclusive of transgender people using the trial eligibility criteria. We compared trials (therapeutic area, trial design, enrolment), summarized trials registered from 2008 onward and characterized participant enrolment for Inclusive trials with primary trial publications. We summarized continuous data using median (range), categorical data using frequencies and percentages and compared trial characteristics using Fisher's exact test. Ninety-seven trials represented transgender people. Characteristics were similar between 85 Inclusive and 12 Exclusive trials. Among Inclusive trials, 58% focused on infectious diseases (e.g. treatment or prevention of HIV and COVID-19), 15% on mental health (e.g. post-traumatic stress disorder, substance use-related disorders), and the remainder focused on endocrine (9%), pain (5%), digestive system disorders (1%) and neoplasms (1%). Twenty (of 25) trials reported enrolment of transgender participants in primary trial publications or reported results. Transgender-inclusive trials have increased since 2008. Most trials focused on infectious diseases and mental health. Investigators should increase opportunities to include of transgender people in trials of drugs and biologics for chronic diseases.

Associations between child maltreatment and hospital admissions for alcohol and other substance use-related disorders up to 40 years of age: Results from the Childhood Adversity and Lifetime Morbidity study.

Evidence on the associations between child maltreatment (CM), alcohol use disorders (AUDs) and other substance use disorders (SUDs) comes largely from retrospective studies. These rely on self-reported data, which may be impacted by recall bias. Using prospective CM reports to statutory agencies, we measured associations between CM notifications and inpatient admissions for AUDs and SUDs up to 40 years of age. Observational study linking administrative health data from Queensland, Australia to prospective birth cohort data comprising both agency-reported and substantiated notifications of CM. Outcomes were inpatient admissions for AUDs and SUDs based on ICD-10-Australian modification (AM)-coded primary diagnoses. Unadjusted and adjusted logistic regression analyses were undertaken. Ten per cent (n = 609) of the cohort had a history of agency-reported or substantiated CM notifications before age 15. These individuals had higher adjusted odds of being admitted for AUDs and SUDs. For AUDs, the adjusted odds of inpatient admission were 2.86 [95% confidence interval (CI) = 1.73-4.74] greater where there was any previous agency-reported CM and 3.38 (95% CI = 1.94-5.89) greater where there was any previous substantiated CM. For SUDs, the adjusted odds of inpatient admission were 3.34 (95% CI = 2.42-4.61) greater where there was any previous agency-reported CM and 2.98 (95% CI = 2.04-4.36) greater where there was any previous substantiated CM. People with a history of child maltreatment appear to have significantly higher odds of inpatient admissions for alcohol use disorders and other substance use disorders up to 40 years of age compared to people with no history of child maltreatment.

Comparing pregnancy and pregnancy outcome rates between adolescents with and without pre-existing mental disorders.

There are limited population-based data on the role of mental disorders in adolescent pregnancy, despite the presence of mental disorders that may affect adolescents' desires and decisions to become pregnant. This study aimed to examine the relationship between specific types of mental disorders and pregnancy rates and outcome types among adolescents aged 13-19 years, using single-year age groups. We conducted a retrospective cohort study using data from the Merative™ MarketScan Research Databases. The study population consisted of females aged 13-19 years with continuous insurance enrollment for three consecutive calendar years between 2005 and 2015. Pregnancy incidence rates were calculated both overall and within the different categories of mental disorders. The presence of mental disorders, identified through diagnosis codes, was classified into 15 categories. Pregnancy and pregnancy outcome types were determined using diagnosis and procedure codes indicating the pregnancy status or outcome. To address potential over- or underestimations of mental disorder-specific pregnancy rates resulting from variations in age distribution across different mental disorder types, we applied age standardization using 2010 U.S. Census data. Finally, multivariable logistic regression models were used to examine the relationships between 15 specific types of mental disorders and pregnancy incidence rates, stratified by age. The age-standardized pregnancy rate among adolescents diagnosed with at least one mental disorder was 15.4 per 1,000 person-years, compared to 8.5 per 1,000 person-years among adolescents without a mental disorder diagnosis. Compared to pregnant adolescents without a mental disorder diagnosis, those with a mental disorder diagnosis had a slightly but significantly higher abortion rate (26.7% vs 23.8%, P-value < 0.001). Multivariable logistic regression models showed that substance use-related disorders had the highest odds ratios (ORs) for pregnancy incidence, ranging from 2.4 [95% confidence interval (CI): 2.1-2.7] to 4.5 [95% CI:2.1-9.5] across different age groups. Overall, bipolar disorders (OR range: 1.6 [95% CI:1.4-1.9]- 1.8 [95% CI: 1.7-2.0]), depressive disorders (OR range: 1.4 [95% CI: 1.3-1.5]- 2.7 [95% CI: 2.3-3.1]), alcohol-related disorders (OR range: 1.2 [95% CI: 1.1-1.4]- 14.5 [95% CI: 1.2-178.6]), and attention-deficit/conduct/disruptive behavior disorders (OR range: 1.1 [95% CI: 1.0-1.1]- 1.8 [95% CI: 1.1-3.0]) were also significantly associated with adolescent pregnancy, compared to adolescents without diagnosed mental disorders of the same age. This study emphasizes the elevated rates of pregnancy and pregnancy ending in abortion among adolescents diagnosed with mental disorders, and identifies the particular mental disorders associated with higher pregnancy rates.

Cannabis use in the UK: a quantitative comparison of individual differences in medical and recreational cannabis users.

There is a paucity of research, especially in the UK, that investigates individual differences in both medical and recreational cannabis users. A cross-sectional survey study design was used to assess recreational cannabis users and medical cannabis users currently living in the UK. Recreational cannabis users were invited to take part via social media. Medical cannabis users were recruited from Sapphire Medical Clinics, London, UK, which provides treatment with prescribed cannabis-based medicinal products. Demographic data and cannabis use frequency, as well as post-traumatic stress disorder symptoms (PCL-5), depression symptoms (Centre for Epidemiological Studies Depression Scale), trait and state anxiety (State-Trait Anxiety Inventory), and cannabis use motives [Comprehensive Marijuana Motives Questionnaire (CMMQ)] were collected. The Chi-square and independent-sample t-tests were used for the comparison of categorical variables and normally distributed continuous variables. Data were analyzed using analyses of variance (ANOVAs) and t-tests. Statistical significance was considered where the value of p was <0.05. The survey was completed by 161 participants. Medical cannabis users were older, consumed cannabis more often, had a higher "Sleep" motive on the CMMQ, and had a higher prevalence in self-reporting current diagnoses of neurological problems, mood disorders, and anxiety disorders (p < 0.05). Recreational cannabis users had higher scores on several motives for use (e.g., "Enjoyment," "Coping," "Experimentation," "Boredom," and "Celebration") and higher state anxiety scores (p < 0.05). The most common motives for cannabis use in both groups were "Enjoyment," "Low Risk," and "Sleep." There were no differences between groups in gender, "Low-Risk" motive, post-traumatic stress disorder symptoms, depression scores, trait anxiety scores, self-reported prevalence of substance use-related disorders, and past consumption of alcohol, tobacco, or caffeine (p > 0.05). The current study not only demonstrates a difference in age and motivations for cannabis consumption between recreational and medical cannabis users but also shows areas of potential overlap, including mental health outcomes, past substance use, and gender. These UK-specific findings indicate that recreational cannabis users experience higher state anxiety, highlighting the need for further evaluation of potential anxiogenic/anxiolytic properties of cannabis. These findings demonstrate the importance of researching individual differences in cannabis users and hold significant implications for future research, clinical practice, and legislation.

Impact of global public health days on online health-information-seeking behavior related to substance use: An analysis of five-year data.

The United Nations Organizations observe various global public health days (GPHDs) (also known as world days) throughout the year. We aimed to assess the impact of GPSDs on online health information-seeking behavior related to substance use in the Indian context. We used the Google Trends data for this study using standard guidelines. We conducted a topic search for the query "Substance abuse" to capture online information-seeking behavior (OHISB) for substance use disorder-related searches. The data were analyzed using the Joinpoint Regression software. Joinpoint regression model analysis was conducted to determine the statistically significant daily percent change (DPC) in the RSV trend. We found that there were significant changes in OHISB for substance use-related disorders on the International Day Against Drug Abuse and Illicit Trafficking over the last five years. The increase in the pattern of online search for substance use-related information was not observed around the World No Tobacco Day, World Mental Health Day, and World Suicide Prevention Day. Since most of these world health days are likely to continue to be observed in the coming years, it is important to regularly assess their impact as well as make the necessary modifications to make them more effective in achieving the desired objectives.

USE OF PSYCHIATRIC RISK FACTORS IN PREDICTING 10 YEAR CARDIOVASCULAR RISK FOR CHINESE PATIENTS WITH SCHIZOPHRENIA

Abstract Patients with schizophrenia are known to have excessive cardiovascular morbidity. Traditional Framingham risk prediction models do not consider additional risk attributable to factors related to psychiatric illness and treatment. The Framingham risk scores also tend to over-estimate cardiovascular risk in Chinese cohorts. This study aimed to develop a 10-year cardiovascular risk prediction model using routine clinical data from an electronic health database in Hong Kong. We identified a cohort of 39,449 patients who were diagnosed with schizophrenia between Year 2005 and 2015 and had no history of cardiovascular disease (CVD). Cox proportional hazards regression models were employed to determine psychiatric and clinical risk factors influencing the timing of incident CVD over 10 years. Psychiatric variables of interest included comorbid psychiatric disorders, duration of schizophrenia, use of antidepressant, use of first- or second-generation antipsychotics (FGA &amp; SGA) at baseline and duration of exposure to FGA and SGA. The main analysis showed that comorbid substance use-related disorders (HR = 1.52; 95% CI 1.22 – 1.90; P &amp;lt; 0.001) increased CVD risk and each year of cumulative exposure to FGA increased CVD risk by 2% (HR = 1.02; 95% CI 1.01 – 1.04; P = 0.001). The use of antidepressant predicted a higher CVD risk in female patients (HR 1.19; 95% CI 1.02 – 1.38; P = 0.028). Our risk model predicted that 20.6% of patients had a CVD risk ≥ 20% over 10 years. Our risk models may offer an accessible clinical tool to help monitor cardiovascular risk in patients with schizophrenia.

Transdiagnostic Connectome-Based Prediction of Craving.

Craving is a central construct in the study of motivation and human behavior and is also a clinical symptom of substance and non-substance-related addictive disorders. Thus, craving represents a target for transdiagnostic modeling. The authors applied connectome-based predictive modeling (CPM) to functional connectivity data in a large (N=274) transdiagnostic sample of individuals with and without substance use-related conditions, to predict self-reported craving. Functional connectomes derived from three guided imagery conditions of personalized appetitive, stress, and neutral-relaxing experiences were used to predict craving rated before and after each imagery condition. The generalizability of the "craving network" was tested in an independent sample using functional connectomes derived from a cue-induced craving task collected before and after fasting to predict craving rated during fasting. CPM successfully predicted craving, thereby identifying a transdiagnostic "craving network." Anatomical localization of model contribution suggested that the strongest predictors of craving were regions of the salience, subcortical, and default mode networks. As external validation, in an independent sample, the "craving network" predicted food craving during fasting using data from a cue-induced craving task. These data provide a transdiagnostic perspective to a key phenomenological feature of addictive disorders-craving-and identify a common "craving network" across individuals with and without substance use-related disorders, thereby suggesting a neural signature for craving or urge for motivated behaviors.

Digital screening and brief intervention for illicit drug misuse in college students: A mixed methods, pilot, cluster, randomized trial from India

Adolescence and early adulthood are vulnerable periods for substance use-related disorders later in life. The use of internet-enabled interventions can be useful, especially in low-resource settings. To examine the feasibility, acceptability, and preliminary effectiveness of single-session digital screening and brief intervention (d-SBI) for illicit drug misuse in college students and explore barriers and facilitators of d-SBI. Design: Mixed-methods, pilot cluster randomized trial. Four conveniently selected colleges were randomized into intervention and control groups. 219 students were screened, and 37 fulfilled eligibility. Twenty-four completed follow-ups. In-depth interviews were done with ten students. Intervention and Comparator: Following a digital screening, Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) based brief intervention was provided in the d-SBI group. The control group received brief education. Acceptability was assessed by direct questions and usage statistics. ASSIST scores of groups were assessed at baseline and 3 months. Inductive coding of the interview transcript was done. More than 50% of participants found d-SBI user-friendly, appropriate, and useful. Eighty percent of users, who logged in, completed screening. Per-protocol analysis showed a reduction in cannabis-ASSIST score over 3 months. The mean ASSIST score for other drugs combined did not differ significantly between groups. The difference in risk transition (moderate to low) was not significant. Qualitative analysis revealed three overarching themes- recruitment, engagement, and behavior change. Digital SBI for drug misuse is feasible among college students. d-SBI might be effective in reducing cannabis use.

Present hedonism and future time perspectives predicting hypersexuality and problematic pornography use

The Time Perspective (TP) theory (i.e., the psychological experience regarding time) was often examined in association with different addictive behaviors, and the different TPs (i.e., Past Positive, Past Negative, Present Hedonistic, Present Fatalistic, and Future TPs) demonstrated different relationship patterns with them. However, most studies were conducted in relation to substance use-related disorders, leaving crucial knowledge gaps concerning the associations between TPs and potential behavioral addictions. The aim of the present study was to examine the associations between the five TP dimensions, hypersexuality, and problematic pornography use (PPU), considering potential gender differences. Participants from two independent samples (N1 = 554; N2 = 453) completed a self-report survey on TPs and sexual behaviors. Structural equation modeling results indicated that the Present Hedonistic TP had a positive, moderate, and the Future TP had a negative, weak association with hypersexuality in both samples. Only the Present Hedonistic TP had a significant, positive, weak-to-moderate association with PPU across the samples. The explained variances of the models were higher in case of hypersexuality (28 and 27%, respectively), than in case of PPU (1 and 14%, respectively). No significant gender differences were observed. In line with previous findings concerning other predictors of hypersexuality and PPU, the results of the present study suggest that hypersexuality and PPU may differ from each other in terms of their TP background. Yet, present hedonism, which is related to impulsivity, may play an important role in both problematic sexual behaviors, suggesting that interventions focusing on this TP might be successful in reducing hypersexuality and PPU.

Decreasing Psychiatric Emergency Visits, but Stable Addiction Emergency Visits, During COVID-19-A Time Series Analysis 10 Months Into the Pandemic.

Background: The COVID-19 pandemic has been suspected to increase mental health problems, but also to possibly lead to a decreased treatment seeking, for example due to fear of attending hospital. Early findings demonstrate decreased treatment seeking for mental health, which may differ across diagnostic groups. This study aimed to examine treatment uptake at a general psychiatry emergency unit and at an addiction psychiatry emergency unit in Malmö, Sweden, separately. In addition, the study aimed to investigate treatment uptake for different diagnostic groups—during and prior to the COVID-19 pandemic.Methods: Monthly data for number of unique patients and number of contacts were extracted for the three-year period of January 2018 through December 2020. Data from each facility were analyzed separately for women, men and patients with psychotic, affective, anxiety and substance use-related disorders. Interrupted time series were used to demonstrate possible effects of COVID-19.Results: COVID-19 was associated with a marked decrease in treatment contacts, both for women and men, in the general psychiatry emergency unit—driven by a significant decrease in anxiety-related disorders (p < 0.001) and affective disorders (p < 0.01)—but not in psychotic or substance use disorders (SUDs). Also, in the addiction psychiatry emergency unit, no significant impact of COVID-19 was seen.Conclusions: COVID-19 may decrease treatment uptake for acute affective and anxiety-related disorders. Given the hypothesized increase in the population regarding these conditions, societal efforts are needed to facilitate adequate treatment for these patients during the COVID-19 pandemic. Society should also remain vigilant with respect to SUDs during the pandemic.

The Pattern of Substance Abuse in the Psychiatry Department of a Tertiary Care of Srinagar Hospital, Jammu and Kashmir, India

Background: Substance-use related disorders (SUD) are a major public health concern worldwide, especially in developing nations. Currently, it is characterized by high rates of mortality and morbidity. Moreover, through increased utilization of healthcare services, it causes both direct and indirect significant medical expenditures. Objectives: The current study aimed to evaluate the pattern of Substance abuse in the department of psychiatry of a Tertiary Care Hospital, Srinagar, Jammu, and Kashmir, India. Methods: This is a descriptive, cross-sectional, and open study conducted in the psychiatry inpatient department of a tertiary care hospital, Srinagar, Jammu, and Kashmir, India, for 7 months (January to May 2020). Results: Over a period of seven months, a total of 135 participants were recruited (105 males and 30 females). Most of them were Muslim (96.29%), married (68.14%), and living as a nuclear family (75.55%). Tobacco (Nicotine) was the most commonly used substance by those admitted to the psychiatry ward (62.96%), followed by cannabis (11.11%) and opioids (11.11%). The most comorbidity associated with substance abuse was psychiatric disorders (36.84%), followed by neurological disorders (21.05%), and gastrointestinal disorders (7.89%). Among those with psychiatric disorders, 14 (10.37%) had mood (bipolar) disorders. A total of 1129 medicines were prescribed for 135 patients. The mean ± standard error of the mean (SEM) of the prescribed medicines was 8.48 ± 3.3. The average number of drugs per encounter was 8.48%. Conclusions: In this study, cigarette smoking (nicotine) was the most commonly abused substance. It can be justified by the fact that Kashmir is a conflict zone, and many people suffer from the post-traumatic stress disorder. Hence, a collaborated effort is necessary to improve the prescribing pattern and to enhance the rational use of medications for better treatment outcomes.

Prevalence of mental disorders among elderly men: a systematic review and meta-analysis.

Elderly men have been characterized as a group vulnerable to suicide, motivated by loneliness, loss of loved ones and feelings of uselessness to family members. To ascertain the prevalence of different mental disorders among elderly men who attempted suicide. Systematic review of observational studies developed as a result of a partnership between two postgraduate schools (Lagarto and Uberlândia). An electronic search was performed in eight electronic databases, including "grey literature", in January 2019. Observational studies that assessed mental disorders among men older than 60 years who attempted suicide were eligible for inclusion. Among the disorders evaluated, mood disorders had the highest prevalence (42.0%; 95% confidence interval, CI: 31.0-74.0%; I2: 0.0%; P = 0.763), followed by substance use-related disorders (41.0%; 95% CI: 8.0-74.0%; I2: 96.4; P < 0.001) and, lastly, schizophrenic disorders (5.0%; 95% CI: 0.0%-14.0%; I2: 80.3%; P = 0.024). It seems that mood disorders and substance use-related disorders are quite prevalent among elderly men with mental disorders who attempted suicide. It is important to consider the role of healthcare services in making early diagnoses of mental disorders among elderly men, in order to diminish the chances of suicide attempts among them.

Impulsivity and Impulsivity-Related Endophenotypes in Suicidal Patients with Substance Use Disorders: an Exploratory Study

Suicidal behavior (SB) is a major problem in patients with substance use disorders (SUDs). However, little is known about specific SB risk factors in this population, and pathogenetic hypotheses are difficult to disentangle. This study investigated some SB and SUD-related endophenotypes, such as impulsivity, aggression, trait anger, and risk-taking behaviors (RTBs), in forty-eight patients with SUDs in relation to lifetime history of suicide attempts (SAs). Disorders related to alcohol, cannabis, cocaine, opiates, and hallucinogenic drugs were included. Lifetime SAs was significantly associated with both higher impulsivity and higher aggression, but not with trait anger. A higher number of RTBs were associated with lifetime SAs and higher impulsivity, but not with aggression and trait anger. Assessing these endophenotypes could refine clinical SB risk evaluation in SUDs patients by detecting higher-risk subgroups. An important limitation of this study is exiguity of its sample size. Its primary contribution is inclusion of all SUD types.

Trend of emergency department presentations with a mental health diagnosis in Australia by diagnostic group, 2004-05 to 2016-17.

To examine trends of ED presentations with a mental health (MH) diagnosis in Australia and its jurisdictions by diagnostic group between 2004-05 and 2016-17. Data comprised ED presentations with a principal diagnosis of ICD-10-AM F00-F99 (MHdx ) captured within the National Non-Admitted Patient Emergency Department Care Database. Trends in absolute number and rates of MHdx presentations per 10 000 population were assessed as differences (x-fold) and annual growth rates (average and compound). Increased presentation rates were observed for most diagnostic groups, except for mental retardation (F70-F79) and mood disorders (F30-F39). The greatest absolute increase was for psychoactive substance use-related disorders (F10-F19), and relative increase, unspecified mental disorder (F99). There was differentiation across jurisdictions regarding rates of and growth in presentations. In 2016-17, rates at least twice the national average were observed for psychoactive substance-use (F10-F19), schizophrenia and psychotic disorders (F20-F29) and childhood and adolescence onset disorders (F90-F98) in the Northern Territory, F90-F98 in South Australia, personality disorders (F60-F69) in Tasmania and unspecified mental disorder (F99) in New South Wales. The most marked growth was observed for F99 in New South Wales. Between 2004-05 and 2016-17, rates of ED presentations increased across most MH diagnostic groups, but particularly psychoactive substance use-related disorders. To reduce the need for MH crisis care in Australian EDs, strategies are required to reduce psychoactive substance use in the community, and policies may be needed to strengthen the capability of community MH services and primary care professionals to recognise, diagnose and treat earlier in the course of illness.

Emergency Department Utilization for Substance Use-Related Disorders and Assessment of Treatment Facilities in New York State, 2011–2013

Background: Annually, 1.8 million New York (NY) residents experience substance use disorders (SUDs). Even though emergency departments (EDs) continue to experience high numbers of SUD-related visits, only 15% receive treatment. Objectives: This study estimates hospital-based EDs rates for SUDs in the State of New York. Also, the geographic distribution of substance use treatment centers and EDs are mapped to correlate utilization with access to care. Methods: The 2011–2013 Healthcare Cost and Utilization Project’s NY State Emergency Department Database provided information on utilization of services in EDs, charges, diagnoses, and discharge, as well as patient demographic variables. All patients within NY who had visited the ED for SUDs comprised the study population. Geographic mapping of EDs and substance abuse treatment centers at the county-level is based on data from the National Emergency Department Inventory and National Survey of Substance Abuse Treatment Services, respectively. Results: A total of 492,419 ED visits for SUDs were reported through 2011–2013. Despite NY’s Medicaid expansion in 2012, ED visits increased in 2013. About $856 million was spent in treating SUDs in EDs, with average charge of $1,764 per visit. Conclusions/Importance: Alcohol and drug-induced mental disorders are increasingly prevalent in New York’s EDs. There is a need to develop health policies and programs to improve access to care for SUDs in urban states.

Substance use disorders in adolescent and young adult relatives of probands with bipolar disorder: What drives the increased risk?

BackgroundAdults with bipolar disorder (BD) have higher rates of substance use disorders (SUDs) compared to the general population. SUD rates in young offspring/relatives of BD probands, as well as factors which drive those rates, are not as well-characterized. MethodsWe aimed to examine SUD prevalence among adolescent/young adult offspring and relatives of probands with and without BD. Data were collected from five sites in the US and Australia during 2006–2011. Youth offspring/relatives (“Relatives of BD probands;” n=267; mean age=16.8years; ±2.9S.D.), identified through a proband family member with DSM-IV BD (Type I or II), were compared to offspring/relatives of control probands (“relatives of control probands;” n=149; mean age=17.4years; ±2.9S.D.). Logistic regression with generalized estimating equations was used to compare the groups across a range of substance use and SUD variables. Odds ratios were calculated for lifetime prevalence of substance outcomes. ResultsBivariate analyses showed DSM-IV SUDs were more prevalent among relatives of BD probands than among relatives of control probands (29% vs. 18%; p=0.01). Generalized estimating equation models showed BD mood and childhood-onset externalizing disorders in adolescent and young adult relatives to each significantly increase the odds (OR=2.80–3.17; p<0.02) for the development of several substance variables among all relatives, whereas the risk of SUDs in relatives was not increased when the relatives had no mood or externalizing disorders themselves. ConclusionRelatives of BD probands with lifetime mood and externalizing disorders report more substance use/SUDs than relatives of control probands. In contrast, SUD outcomes in relatives of BD probands without mood or externalizing disorders were no different from control relatives without psychopathology. Early recognition and treatment of psychiatric disorders may lead to less substance use in this highly vulnerable population.

Liver Disease and Fibrosis Assessment in Substance Use-Related Disorders.

Substance users have the highest prevalence of hepatitis C virus (HCV) infection but have rarely been treated, largely because of their mistrust of the health care system, misconceptions about the consequences of the infection, and concerns regarding interferon-related side effects. With the development of highly efficacious, interferon-free therapeutic regimens without significant side effects, the concept of colocating HCV and substance use treatment would appear to be highly feasible. This process has been further facilitated by widespread clinical adaptation of noninvasive assays for fibrosis assessment, which could be performed routinely in substance use treatment facilities. The most commonly used noninvasive fibrosis assessment methods are serum marker indexes and transient elastography, both of which are very accurate in detecting cirrhosis or the absence of fibrosis, but much less successful in identifying intermediate fibrosis stages. The effect of drugs of abuse on the liver is not completely understood or sufficiently studied. There are no indications that heroin and cocaine affect fibrosis progression, but some recreational drugs (eg, alcohol and cannabis) can induce hepatic injury. In addition, knowledge gaps exist on the effect of impaired liver function on metabolism or transport of agents used to treat substance disorders as well as their interactions with HCV antivirals.

Examining the association between attention deficit hyperactivity disorder and substance use disorders: A familial risk analysis

ObjectiveThe main aim of this study was to use familial risk analysis to examine the association between attention deficit hyperactivity disorder (ADHD) and substance use disorders (SUDs) attending to sex effects and the specificity of alcohol and drug use disorder risks. MethodsSubjects were derived from two longitudinal case-control family studies of probands aged 6–17 years with and without DSM-III-R ADHD of both sexes and their first degree relatives followed from childhood onto young adult years. Cox proportional hazard models were used to estimate rates of ADHD and SUDs (any SUD, alcohol dependence, and drug dependence). Logistic regression was used to test both co-segregation and assortative mating. ResultsOur sample included 404 probands (ADHD: 112 boys and 96 girls; Control: 105 boys and 91 girls) and their 1336 relatives. SUDs in probands increased the risk for SUDs in relatives irrespective of ADHD status. The risk for dependence to drug or alcohol in relatives was non-specific. There was evidence that even in the absence of a SUD in the proband, ADHD by itself increased the risk of SUDs in relatives. Proband sex did not moderate the familial relationship between ADHD and SUDs. There was evidence of co-segregation between ADHD and SUD. ConclusionsFindings indicate that various independent pathways are involved in the transmission of SUD in ADHD and that these risks were not moderated by proband sex. ADHD children and siblings should benefit from preventive and early intervention strategies to decrease their elevated risk for developing a SUD.
