Trends in prescription drug abuse and dependence, co-occurrence with other substance use disorders, and treatment utilization: results from two national surveys

Patient perspectives on emergency department initiation of medication for alcohol use disorder

OBJECTIVE

Alcohol use disorder (AUD) is a leading cause of preventable death and is a frequent diagnosis in the emergency department (ED). Treatment in the ED, however, typically focuses on managing the sequelae of AUD, such as acute withdrawal, rather than addressing the underlying addiction. For many patients, these ED encounters are a missed opportunity to connect with medication for AUD. In 2020, our ED created a pathway to offer patients with AUD treatment with naltrexone (NTX) during their ED visit. The aim of this study was to identify what barriers and facilitators patients perceive to NTX initiation in the ED.

METHODS

Adopting the theoretical framework of the behavior change wheel (BCW), we conducted qualitative interviews with patients to elicit their perspectives on ED initiation of NTX. Interviews were coded and analyzed using both inductive and deductive approaches. Themes were categorized according to patients' capabilities, opportunities, and motivations. Barriers were then mapped through the BCW to design interventions that will improve our treatment pathway.

RESULTS

Twenty-eight patients with AUD were interviewed. Facilitators of accepting NTX included having recently experienced sequelae of AUD, rapid management of withdrawal symptoms by the ED provider, having a choice between intramuscular and oral formulations of the medication, and experiencing positive interactions in the ED that destigmatized the patient's AUD. Barriers to accepting treatment included lack of provider knowledge about NTX, dependence on alcohol as self-treatment for psychiatric trauma and physical pain, perceived discriminatory treatment and stigma about AUD, aversion to potential side effects, and lack of access to continued treatment.

CONCLUSIONS

Initiation of treatment of AUD with NTX in the ED is acceptable to patients and can be facilitated by knowledgeable ED providers who create a destigmatizing environment, effectively manage withdrawal symptoms, and connect patients to providers who will continue treatment.

Rural communities face more than an opioid crisis: Reimagining funding assistance to address polysubstance use, associated health problems, and limited rural service capacity

PURPOSE

Rural communities in the United States face unique challenges related to the opioid epidemic. This paper explores the substances and substance-related health problems that pose the greatest concern to rural communities that received funding to address the opioid epidemic and examines their reported capacity to address these challenges.

METHODS

This paper analyzed data collected as part of quarterly progress reporting from multisector consortiums across 2 cohorts of grantees funded to reduce the morbidity and mortality of opioids. Consortium project directors ranked the top 3 issues in their community in each of the following categories: (1) drugs of concern; (2) drugs with the least capacity to address; (3) related problem areas of concern (eg, neonatal abstinence syndrome [NAS]); and (4) related problem areas with the least capacity to address.

FINDINGS

Methamphetamines, fentanyl, and alcohol were the substances rated as most problematic in rural communities funded to address the opioid epidemic across all reporting periods. Over 40% of respondents ranked methamphetamine as a top concern and the substance they had the least capacity to address. This was nearly double the percentage of the next highest-ranked substance (fentanyl). Overdoses, NAS, and viral hepatitis constituted the top-ranking related concerns, with limited capacity to address them.

CONCLUSIONS

Multiple drug and concomitant problems coalesced on rural communities during the opioid epidemic. Funding communities to address substance use disorders and related problems of concern, rather than targeting funding toward a specific type of drug, may result in better health outcomes throughout the entire community.

Polysubstance Use Patterns Associated With HIV Disease Severity Among Those With Substance Use Disorders: A Latent Class Analysis

OBJECTIVE

Polysubstance use is common among people with HIV infection (PWH) and with substance use disorder (SUD), but its effects are understudied. We aimed to identify polysubstance use patterns over time and assess their associations with HIV disease severity.

METHOD

In 233 PWH with current or past SUD, latent class analysis identified polysubstance use patterns based on the Alcohol Use Disorders Identification Test-Consumption and past-30-day use of cannabis, cocaine, opioids, and tranquilizers at baseline. We categorized changes in use patterns and tested associations between those changes and CD4 count and HIV viral suppression at 12 months in linear and logistic regressions.

RESULTS

Three patterns were identified at baseline: 18% did not use any substance (NONE--a priori defined); 63% used mostly cannabis and alcohol (CA); and 19% used opioids along with other drugs, including cocaine, tranquilizers, cannabis, and alcohol (MULTI). At 12 months, 40% moved from a high to a lower substance use class (MULTI to CA, either to NONE) or remained as NONE, 43% were in CA both times and 17% increased (NONE to CA, either to MULTI) or remained as MULTI. The adjusted mean CD4 count (for baseline covariates and baseline CD4 count) was significantly lower among participants increasing or remaining in MULTI (523, 95% CI [448, 598], cells/mm3) compared with those who decreased/abstained throughout (607, 95% CI [552, 663], p = .02). No significant difference was observed for HIV viral suppression.

CONCLUSIONS

We identified distinct polysubstance use patterns among PWH with SUD: cannabis/alcohol and opioids with alcohol and other drugs. Changes over time toward fewer substances/no use were associated with lower HIV disease severity based on CD4 count but not based on HIV viral suppression.

A network approach to substance use, internalizing, and externalizing comorbidity in U.S. adults

INTRODUCTION

Use of conventional cigarettes (CIG), alcohol, marijuana, and sedatives [i.e., benzodiazepines and barbiturates]) commonly co-occur with internalizing and externalizing disorders. It is unclear how these relationships extend to electronic cigarettes (ECIGs) and prescription drugs not prescribed (i.e., sedatives, tranquilizers, and painkillers [PDNP]), and whether they differ by gender.

METHODS

Adult data (N = 30,211) from Wave 1 (2013-2014) of the Population Assessment of Tobacco and Health Study were used to estimate a network of current or past-month use for six substances, experiencing four internalizing symptoms in the past month, and experiencing seven externalizing symptoms in the past month. Visual comparisons, global strength invariance, network structure invariance, and edge strength invariance were tested to detail substance use and internalizing/externalizing symptom networks.

RESULTS

Overall, networks were consistent between men and women. The strongest substance use/mental health symptom connections estimated as edge-weights (EW) were between marijuana with lying (EW = 0.60, 95% CI = 0.49; 0.70), marijuana with engaging in fights (EW = 0.54, 95% CI = 0.27; 0.81), PDNP with having trouble sleeping (EW = 0.53, 95% CI = 0.40; 0.66), and alcohol and impulsivity (EW = 0.48, 95% CI = 0.42; 0.53).

DISCUSSION

There were many weak connections throughout the substance use and internalizing/externalizing network. A few important connections were identified and encourage future study. In particular, PDNP was most strongly associated with internalizing symptoms. Marijuana, alcohol and PDNP use were most strongly associated with externalizing symptoms.

Surveillance, Self-Governance, and Mortality: The Impact of Prescription Drug Monitoring Programs on U.S. Overdose Mortality, 2000-2016

Policy mechanisms shaping population health take numerous forms, from behavioral prohibitions to mandates for action to surveillance. Rising drug overdoses undermined the state's ability to promote population-level health. Using the case of prescription drug monitoring programs (PDMPs), we contend that PDMP implementation highlights state biopower operating via mechanisms of surveillance, whereby prescribers, pharmacists, and patients perceive agency despite choices being constrained. We consider whether such surveillance mechanisms are sufficient or if prescriber/dispenser access or requirements for use are necessary for population health impact. We test whether PDMPs reduced overdose mortality while considering that surveillance may require time to reach effectiveness. PDMPs reduced opioid overdose mortality 2 years postimplementation and sustained effects, with similar effects for prescription opioids, benzodiazepines, and psychostimulants. Access or mandates for action do not reduce mortality beyond surveillance. Overall, PDMP effects on overdose mortality are likely due to self-regulation under surveillance rather than mandated action.

Preventing Adolescent Opioid Misuse: Racial/Ethnic Differences in the Protective Effects of Extracurricular Activities

OBJECTIVE

Participation in extracurricular activities has been largely shown to be protective against adolescent substance use. However, research has yet to examine whether extracurricular activities are specifically protective against adolescent opioid misuse and if these protective effects vary by race/ethnicity. This study focuses on a high-risk population for drug use (i.e., justice-involved adolescents [JIAs]) that is not often captured in population-based surveys. The goals of the current study were twofold: (a) determine the prevalence of opioid misuse for White, Black, and Latinx JIAs and (b) assess the influence of participation in extracurricular activities on opioid misuse risk among White, Black, and Latinx JIAs.

METHOD

Using data from the Florida Department of Juvenile Justice (n = 65,248), multivariate logistic regression models were estimated to determine which racial/ethnic groups experienced protective effects from participation in extracurricular activities.

RESULTS

Results show that 2.3% of the sample met criteria for past-30-day opioid misuse and participation in extracurricular activities lowered the risk for opioid misuse by 36%. However, although involvement in extracurricular activities was protective for White and Latinx youth, Black youth received no such protective effect.

CONCLUSIONS

This study provides evidence of a fairly strong protective effect (36% risk reduction) for extracurricular activities against opioid misuse, but our results caution against assuming that youth from all racial/ethnic backgrounds benefit similarly from extracurricular activities because Black adolescents may not experience the same protective benefit that White and Latinx youth receive. Programs should be aware that the protection extracurricular activities offer varies across racial/ethnic lines and tailoring may be warranted to see protective effects for Black youth.

Predicting the Onset of Opioid Use Disorder in the Swedish General Population

OBJECTIVE

Given the public health importance of opioid use disorder (OUD), we sought to understand better its risk predictors in the Swedish general population.

METHOD

We examined the Swedish population, born 1950-1970 (n = 2,092,359), and followed through 2018. Using Cox, logistic, and co-sibling models, we explored associations between a wide range of putative risk factors and a first onset of OUD--assessed through medical, criminal, and pharmacy registers--in the entire cohort and in the cohort wherein prior cases of drug use disorder (DUD) were censored.

RESULTS

OUD was predicted by the following four risk factor domains: (a) externalizing syndromes, especially prior non-opioid DUD; (b) psychopathology; (c) psychosocial factors, including social class and immigrant and marital status; and (d) serious injuries and pain diagnoses. When predicting OUD as the first form of DUD, the importance of pain diagnoses as a predictor increased. Co-sibling analyses suggested that the association of some of these risk factors with OUD onset was likely largely causal, whereas others were a mixture of causal effects and familial confounding. An aggregate risk score from these individual risk factors had reasonable receiver operating characteristic (ROC) curve performance.

CONCLUSIONS

OUD is a multifactorial syndrome for which risk can be meaningfully predicted by prior externalizing syndromes, internalizing and psychotic psychopathology, indicators of psychosocial status, and predictors of pain diagnoses. Some important differences were seen in the prediction of any OUD onset versus OUD onset as the first form of DUD. Much of the effect of these predictors appear, in co-sibling analyses, to likely reflect causal influences.

Longitudinal Analysis of Substance Use Disorder Symptom Severity at Age 18 Years and Substance Use Disorder in Adulthood

IMPORTANCE

Although more than 1 in every 3 US individuals will develop a substance use disorder (SUD) in their lifetime, relatively little is known about the long-term sequelae of SUD symptoms from adolescence through adulthood.

OBJECTIVE

To evaluate the longitudinal associations between adolescents' SUD symptom severity with later medical use of prescription drugs (ie, opioids, sedatives, and tranquilizers), prescription drug misuse (PDM), and SUD symptoms at ages 35 to 50 years.

DESIGN, SETTING, AND PARTICIPANTS

Eleven cohorts of US 12th grade students were followed longitudinally from age 18 years (1976-1986) to age 50 years (2008-2018) in the Monitoring the Future (MTF) study. Baseline surveys were self-administered in classrooms, and follow-ups were conducted by mail. Data were analyzed from June 2021 to February 2022.

EXPOSURE

Response to MTF study between 1976 and 2018.

MAIN OUTCOMES AND MEASURES

Sociodemographic variables were measured at baseline. All bivariate and multivariate analyses use attrition weights to adjust for attrition by age 50 years within the sample. SUD symptoms, prescription drug use, and PDM were measured at baseline and every follow-up.

RESULTS

The sample of 5317 individuals was 51.2% female (2685 participants; 95% CI, 49.6%-52.6%) and 77.9% White (4222 participants; 95% CI, 77.6%-79.1%). Participants were surveyed beginning at age 18 years and ending at age 50 years. The baseline response rate ranged from 77% to 84%, and the 32-year retention rate was 53%. Most adolescents with most severe SUD symptoms at age 18 years had 2 or more SUD symptoms in adulthood (316 participants [61.6%]; 95% CI, 55.7%-66.9%), and this association held for baseline alcohol, cannabis, and other drug use disorder symptoms. Adolescents with the highest SUD symptom severity at age 18 years had the highest adjusted odds of prescription drug use and PDM in adulthood (4-5 symptoms, adjusted odds ratio, 1.56; 95% CI, 1.06-2.32; ≥6 symptoms, adjusted odds ratio, 1.55; 95% CI, 1.11-2.16). The majority of adults using prescribed opioids, sedatives, or tranquilizers (568 participants [52.2%]; 95% CI, 48.4%-55.9%) in the past year had multiple SUD symptoms at age 18 years.

CONCLUSIONS AND RELEVANCE

These findings suggest that most adolescents with severe SUD symptoms do not transition out of symptomatic substance use, and the long-term sequelae for adolescents with more severe SUD symptoms are more deleterious than those for adolescents with no or low severity. Prescribers should be aware that many adults prescribed opioids, sedatives, or tranquilizers had multiple SUD symptoms during adolescence and require careful assessment and monitoring.

Behavioral Willingness, Descriptive Normative Perceptions, and Prescription Stimulant Misuse among Young Adults 18-20

Objective: It is critical to gain further understanding of etiologic factors, such as descriptive normative perceptions and behavioral willingness, that are associated with prescription stimulant misuse (PSM) among young adults. Our primary hypotheses were that descriptive normative perceptions for PSM (i.e., perceptions of how much and how often others engage in PSM) and perceived peer willingness (i.e., perceptions of how open others are to PSM under certain circumstances) would be positively associated with higher willingness to engage in PSM, which in turn would account for significant shared variance with self-reported PSM. Method: Data were collected from a U.S. sample of 18-20-year-olds (N = 1,065; 54.5% females; 70.5% White) recruited for a larger study on alcohol-related risky sexual behavior. Results: Findings indicated higher descriptive normative perceptions and higher perceived peer willingness were associated with higher participants' willingness to engage in PSM. Participants' own willingness was positively associated with PSM. Finally, participants' own willingness to use, descriptive normative perceptions, and perceived peer willingness were associated with higher willingness to engage in PSM, which accounted for significant shared variance with self-reported PSM. Conclusions: Findings suggest the potential utility of personalized feedback interventions for PSM that focus on constructs such as descriptive normative perceptions and behavioral willingness.

Opioid Use Disorder is Associated With Complications and Increased Length of Stay After Major Abdominal Surgery

OBJECTIVE

The objective of this study was to determine the impact of opioid use disorder (OUD) on perioperative outcomes after major upper abdominal surgeries.

SUMMARY OF BACKGROUND DATA

OUD, defined as dependence/abuse, is a national health epidemic. Its impact on outcomes after major abdominal surgery has not been well characterized.

METHODS

Patients who underwent elective esophagectomy, total/partial gastrectomy, major hepatectomy, and pancreatectomy were identified using the National Inpatient Sample (2003-2015). Propensity score matching by baseline characteristics was performed for patients with and without OUD. Outcomes measured were in-hospital complications, mortality, length of stay (LOS), and discharge disposition.

RESULTS

Of 376,467 patients, 1096 (0.3%) had OUD. Patients with OUD were younger (mean 53 vs 61 years, P < 0.001) and more often male (55.1% vs 53.2%, P < 0.001), black (15.0% vs 7.6%, P < 0.001), Medicaid beneficiaries (22.0% vs 6.4%, P < 0.001), and in the lowest income quartile (32.6% vs 21.3%, P < 0.001). They also had a higher rate of alcohol (17.2% vs 2.8%, P < 0.001) and nonopioid drug (2.2% vs 0.2%, P = 0.023) dependence/abuse. After matching (N = 1077 OUD, N = 2164 no OUD), OUD was associated with a higher complication rate (52.9% vs 37.3%, P < 0.001), including increased pain [odds ratio (OR) 3.5, P < 0.001], delirium (OR 3.0, P = 0.004), and pulmonary complications (OR 2.0, P = 0.006). Additionally, OUD was associated with increased LOS (mean 12.4 vs 10.6 days, P = 0.015) and nonroutine discharge (OR 1.6, P < 0.001). In-hospital mortality did not differ (OR 2.4, P = 0.10).

CONCLUSION

Patients with OUD more frequently experienced complications and increased LOS. Close postoperative monitoring may mitigate adverse outcomes.

Breaking the cycle: A public-private partnership to combat the American opioid epidemic

There has been an increased focus on the opioid epidemic in the United States, yet policy-based interventions such as prescription limits, restrictions on doctor shopping, and notification programs for high-volume prescribers have had no significant impact. In this paper, the authors explore a novel public health policy: a joint public-private partnership between the federal government and hospitals to establish long-term treatment centers for patients admitted to the emergency department after an overdose. These centers would provide medication for opioid use disorder, give individuals the necessary support for recovery, and reduce healthcare expenditures. Similar longitudinal strategies may be used in other areas of public health.

Wide variation in inpatient opioid utilization following hepatopancreatic surgery

BACKGROUND

Inpatient opioid utilization following major surgery remains relatively unknown. We sought to characterize inpatient opioid consumption following hepatopancreatic surgery and determine factors associated with the variability in opioid utilization.

METHODS

Adult patients who underwent hepatopancreatic surgery at a single institution were identified. Multimodal pain management strategies assessed included opioids (oral morphine equivalents, OME), acetaminophen, ibuprofen and ketorolac.

RESULTS

Among 2,054 patients, the median total OME utilized was 465 (129-815) during a patient's hospitalization following hepatopancreatic surgery. The interquartile range for total OMEs administered following hepatopancreatic surgery was as high as 940 OMEs (125 oxycodone-5mg pills) following a pancreaticoduodenectomy versus 520 OMEs (69 oxycodone-5mg pills) following a hemi-hepatectomy. Despite relatively high use of acetaminophen post-operatively (n = 1,588, 77.0%), multimodal pain control with acetaminophen and ibuprofen was infrequent (n = 175, 8.5%). Furthermore, individuals with high opioid utilization used on average 147 OMEs (20 oxycodone-5mg pills) the day before discharge versus 44 OME (6 oxycodone-5mg pills) among patients with expected opioid utilization.

CONCLUSIONS

Marked variability in inpatient opioid consumption following hepatopancreatic surgery was noted. Future work is necessary to decrease the variability in inpatient opioid prescribing practices to promote the safe and effective management of pain.

Bibliometric Insights in Genetic Factors of Substance-Related Disorders: Intellectual Developments, Turning Points, and Emerging Trends

Substance-related disorders are a group of medical conditions that affect a person's brain and behavior and lead to an inability to control the use of legal or illegal drug(s) or medication. Substance-related disorder is a serious public health and society problem worldwide. Genetic factors have been proven to have an important role. Researchers have carried out a lot of work in this field, and a large number of research results have been published in academic journals around the world. However, there are few overviews of research progress, presentation, and development trends in this field. In this study, a total of 636 articles related to genetic factors of substance-related disorders were retrieved from the Web of Science (WoS) database from 1997 to 2018, and the scientific literatures were analyzed by bibliometrics. The study found that the United States (US) has maintained a leading position in the field of research, with many core institutions and plenty of high-quality research results. Alcohol use disorder is still the most concerning issue in this field. Over the past 20 years, new techniques such as genome-wide association study (GWAS) based on high-throughput sequencing technology have replaced family studies, twin studies, and retrospective studies in this field. We believe that it is urgent to study the genetic factors of substance-related disorders, which can greatly deepen the understanding of the pathogenesis of substance-related disorders and may provide potential targets for precise treatment of such diseases.

Association of prenatal opiate exposure with youth outcomes assessed from infancy through adolescence

OBJECTIVE

This study examined acute findings and long-term outcome trajectories between birth and adolescence in children with prenatal opiate exposure.

STUDY DESIGN

Ninety children (45 opiate-exposed, 45 non-exposed) completed assessments between 1 month and 15 years of age. Outcome variables (medical, anthropomorphic, developmental, and behavioral) were analyzed at individual time points and using longitudinal statistical modeling.

RESULTS

Opiate-exposed infants displayed transient neurologic findings, but no substantial signs or symptoms long term. There were no group differences in growth, cognitive functioning, or behavior at individual time periods; however, the trajectories of outcomes using longitudinal analyses adjusting for variables known to impact outcome demonstrated increased deficits among opiate-exposed children over time with regards to weight, head circumference, cognitive functioning, and behavior.

CONCLUSIONS

Findings support concerns that maternal opiate use during pregnancy may negatively impact a child's developmental trajectory, which in turn may impose concerns to society (e.g., increased need for social, medical, and/or educational services).

Multiple drug use disorder diagnoses among drug-involved hospitalizations in the United States: Results from the 2016 National Inpatient Sample

BACKGROUND

Having more than one drug use disorders (DUDs) is an increasing public health concern, but it has been understudied. The goal of this study is to investigate the prevalence and patterns of coexisting DUD diagnoses among inpatient hospitalizations due to DUD in the United States.

METHODS

Data were from the 2016 National Inpatient Sample and included hospitalizations with a principal DUD diagnosis for patients aged ≥18 years (i.e., drug-involved hospitalizations, unweighted n = 31,707). The DUD diagnosis profile was categorized into three groups: single, two, and three or more DUD diagnoses. Generalized ordered logit models were used to examine correlates of DUD diagnosis groups.

RESULTS

Among drug-involved hospitalizations, approximately 50.1 % had multiple coexisting DUD diagnoses (2 DUD diagnoses, 32.1 %; ≥3 DUD diagnoses, 18.0 %). Particularly, opioid use disorder accounted for 58.6 % of drug-involved hospitalizations. Among specific opioid-involved hospitalizations, about 51.2 % had multiple DUD diagnoses. The most common secondary DUD diagnoses among opioid-involved hospitalizations included cocaine (21.7 %), cannabis (18.5 %), and sedatives (18.1 %). Adjusted analyses showed that being aged 18-25 years (vs. ≥ 26), living in areas with the lowest quartile of household income (vs. highest), and having a secondary diagnosis of mental disorders or tobacco/alcohol use disorder were associated with increased odds of having multiple DUD diagnoses in the total sample and in the opioid subsample.

CONCLUSIONS

Findings suggest that healthcare providers should increase the awareness of multiple DUDs while treating patients with DUD, especially those with opioid use disorder. More research is needed to better characterize treatment needs for patients with multiple DUDs.

Strengths and weaknesses of existing data sources to support research to address the opioids crisis

Better opioid prescribing practices, promoting effective opioid use disorder treatment, improving naloxone access, and enhancing public health surveillance are strategies central to reducing opioid-related morbidity and mortality. Successfully advancing and evaluating these strategies requires leveraging and linking existing secondary data sources. We conducted a scoping study in Fall 2017 at RAND, including a literature search (updated in December 2018) complemented by semi-structured interviews with policymakers and researchers, to identify data sources and linking strategies commonly used in opioid studies, describe data source strengths and limitations, and highlight opportunities to use data to address high-priority public health research questions. We identified 306 articles, published between 2005 and 2018, that conducted secondary analyses of existing data to examine one or more public health strategies. Multiple secondary data sources, available at national, state, and local levels, support such research, with substantial breadth in data availability, data contents, and the data's ability to support multi-level analyses over time. Interviewees identified opportunities to expand existing capabilities through systematic enhancements, including greater support to states for creating and facilitating data use, as well as key data challenges, such as data availability lags and difficulties matching individual-level data over time or across datasets. Multiple secondary data sources exist that can be used to examine the impact of public health approaches to addressing the opioid crisis. Greater data access, improved usability for research purposes, and data element standardization can enhance their value, as can improved data availability timeliness and better data comparability across jurisdictions.

Pharmacotherapeutic management of co-morbid alcohol and opioid use

Opioid use disorder (OUD) and alcohol use disorder (AUD) are two highly prevalent substance-related disorders worldwide. Co-use of the substances is also quite prevalent, yet there are no pharmacological treatment approaches specifically designed to treat co-morbid OUD and AUD. Here, the authors critically summarize OUD, AUD and opioid/alcohol co-use and their current pharmacotherapies for treatment. They also review the mechanisms of action of opioids and alcohol within the brain reward circuitry and discuss potential combined mechanisms of action and resulting neuroadaptations. Pharmacotherapies that aim to treat AUD or OUD that may be beneficial in the treatment of co-use are also highlighted. Preclinical models assessing alcohol and opioid co-use remain sparse. Lasting neuroadaptations in brain reward circuits caused by co-use of alcohol and opioids remains largely understudied. In order to fully understand the neurobiological underpinnings of alcohol and opioid co-use and develop efficacious pharmacotherapies, the preclinical field must expand its current experimental paradigms of 'single drug' use to encompass polysubstance use. Such studies will provide insights on the neural alterations induced by opioid and alcohol co-use, and may help develop novel pharmacotherapies for individuals with co-occurring alcohol and opioid use disorders.

A two-centre survey of caregiver perspectives on opioid use for children's acute pain management

Background

Given the current opioid crisis, caregivers have mounting fears regarding the use of opioid medication in their children. We aimed to determine caregivers' a) willingness to accept, b) reasons for refusing, and c) past experiences with opioids.

Methods

A novel electronic survey of caregivers of children aged 4 to 16 years who had an acute musculoskeletal injury and presented to two Canadian paediatric emergency departments (ED) (March to November 2017). Primary outcome was caregiver willingness to accept opioids for moderate pain for their children.

Results

Five hundred and seventeen caregivers participated; mean age was 40.9 (SD 7.1) years with 70.0% (362/517) mothers. Children included 62.2% (321/516) males with a mean age of 10.0 (SD 3.6) years. 49.6% of caregivers (254/512) reported willingness to accept opioids for ongoing moderate pain in the ED, while 37.1% (190/512) were 'unsure'; 33.2% (170/512) of caregivers would accept opioids for at-home use, but 45.5% (233/512) were 'unsure'. Caregivers' primary concerns were side effects, overdose, addiction, and masking of diagnosis. Caregiver fear of addiction (odds ratio [OR] 1.12, 95% confidence interval [CI] 1.01 to 1.25) and side effects (OR 1.25, 95% CI 1.11 to 1.42) affected willingness to accept opioids in the emergency department; fears of addiction (OR 1.19, 95% CI 1.07 to 1.32), and overdose (OR 1.15, 95% CI 1.04 to 1.27) affected willingness to accept opioids for at-home use.

Conclusions

Only half of the caregivers would accept opioids for moderate pain, despite ongoing pain following nonopioid analgesics. Caregivers' fears of addiction, side effects, overdose, and masking diagnosis may have influenced their responses. These findings are a first step in understanding caregiver analgesic decision making.

Is the global prevalence rate of adult mental illness increasing? Systematic review and meta-analysis

OBJECTIVES

The question whether mental illness prevalence rates are increasing is a controversially debated topic. Epidemiological articles and review publications that look into this research issue are often compromised by methodological problems. The present study aimed at using a meta-analysis technique that is usually applied for the analysis of intervention studies to achieve more transparency and statistical precision.

METHODS

We searched PubMed, PsycINFO, CINAHL, Google Scholar and reference lists for repeated cross-sectional population studies on prevalence rates of adult mental illness based on ICD- or DSM-based diagnoses, symptom scales and distress scales that used the same methodological approach at least twice in the same geographical region. The study is registered with PROSPERO (CRD42018090959).

RESULTS

We included 44 samples from 42 publications, representing 1 035 697 primary observations for the first time point and 783 897 primary observations for the second and last time point. Studies were conducted between 1978 and 2015. Controlling for a hierarchical data structure, we found an overall global prevalence increase in odds ratio of 1.179 (95%-CI: 1.065-1.305). A multivariate meta-regression suggested relevant associations with methodological characteristics of included studies.

CONCLUSIONS

We conclude that the prevalence increase in adult mental illness is small, and we assume that this increase is mainly related to demographic changes.

Accelerating the Pace of Science: Improving Parenting Practices in Parents with Opioid Use Disorder

A public health emergency exists in the United States as a result of rising overdose deaths related to Opioid Use Disorder (OUD). With the rise of OUD has also come an increase in the number of children exposed to parents who suffer from an OUD. There is a pressing need for parenting interventions for individuals with OUD to provide safe environments for the children being reared in the face of this epidemic. Research on parenting with an OUD is sparse, but it is impractical to move linearly from basic research to program development and implementation given the urgent need for intervention - a trajectory that prior research has established takes approximately 17 years. We have created an outline of strategies that can be used to accelerate the pace of science so that parenting practices are more immediately improved for this population. First, we summarize what is already known about OUD and parenting to characterize mechanisms that existing interventions have targeted and optimal settings for the wide dissemination of implementable interventions. Next, we identify existing interventions that either specifically target parents with OUD or mechanisms specific to parents with OUD. We describe four different approaches for accelerating the pace of science to improve the lives of parents with OUD and their children. By doing so, we hope to provide a roadmap for future researchers and practitioners to deliver more timely evidence-based interventions to address the additional burden placed on families and communities due to the rise in OUD in the United States.

Systematic review to determine which validated measurement tools can be used to assess risk of problematic analgesic use in patients with chronic pain

Background

Misuse of prescription opioids, and other drugs prescribed for chronic pain, has increased, with major concerns about harm. This review was undertaken to identify validated measurement tools for risk assessment and monitoring of chronic non-cancer pain patients being considered for, or currently prescribed, analgesic drugs with abuse potential.

Methods

Selected databases (Embase, Medline, Cochrane library/CENTRAL, PsycINFO, PubMed, CINAHL) were systematically searched for studies evaluating tools for risk of analgesic misuse, either before, or during, analgesic therapy for chronic pain, using predetermined inclusion/exclusion criteria. Two independent reviewers assessed abstracts, selected full texts, extracted data and assessed quality.

Results

30 studies from 1844 met inclusion criteria, including three systematic reviews, with an additional four studies from bibliography review. The studies covered 14 tools pertaining to opioid use, with none for non-opioid analgesics.

Conclusions

For predicting prescription opioid misuse, the pain medication questionnaire (PMQ) and the screener and opioid assessment for patients with pain (SOAPP) had the best evidence; both developed and validated in five separate studies (four each of acceptable quality). The current opioid misuse measure (COMM) performed best screening for current misuse, developed and validated in three studies of acceptable quality. A small number of tools may accurately predict, or identify, opioid misuse. There are none for non-opioid analgesics, where there is a potential need.

The relationship between past 12-month suicidality and reasons for prescription opioid misuse

BACKGROUND

Understanding reasons for prescription opioid misuse can help elucidate suicide prevention efforts. The goal of the current study is to assess associations of reasons for prescription opioid misuse subtypes and suicide-related variables. We also assessed whether prescription opioid misuse differentiates ideators from those who attempt suicide.

METHODS

Using data from the 2015-2017 National Survey of Drug Use and Health (N = 45,074), prescription opioid misuse subtypes were grouped as follows: (a) Pain only, (b) Other reasons, and (c) Mixed reasons (i.e., pain and at least one other reason). Logistic regressions examined associations of misuse subtypes and past 12-month suicide-related variables (ideation, planning, attempts) relative to non-misusers. Logistic regression analyses were also conducted among the subset reporting ideation to assess whether prescription opioid misuse differentiated ideators with no attempt from ideators with an attempt.

RESULTS

In adjusted models, the Pain only and the Other reasons subtypes were associated with ideation and planning, but not attempts. The Mixed reasons subtype had higher odds of suicide ideation and planning compared to those not misusing prescription opioids and the Pain only misuse subtype. The Mixed reasons subtype had higher odds of a suicide attempt only when compared to those not misusing prescription opioids. Prescription opioid misuse was also associated with suicide attempts among the subset of ideators.

CONCLUSIONS

Findings indicate that people misuse prescription opioids for various reasons, and misuse subtypes are associated with past 12-month suicidality. Addressing pain and other reasons for misuse together through use of evidence-based treatments may help mitigate suicide risk.

Internet Searches for Medical Symptoms Before Seeking Information on 12-Step Addiction Treatment Programs: A Web-Search Log Analysis

Background

Brief intervention is a critical method for identifying patients with problematic substance use in primary care settings and for motivating them to consider treatment options. However, despite considerable evidence of delay discounting in patients with substance use disorders, most brief advice by physicians focuses on the long-term negative medical consequences, which may not be the best way to motivate patients to seek treatment information.

Objective

Identification of the specific symptoms that most motivate individuals to seek treatment information may offer insights for further improving brief interventions. To this end, we used anonymized internet search engine data to investigate which medical conditions and symptoms preceded searches for 12-step meeting locators and general 12-step information.

Methods

We extracted all queries made by people in the United States on the Bing search engine from November 2016 to July 2017. These queries were filtered for those who mentioned seeking Alcoholics Anonymous (AA) or Narcotics Anonymous (NA); in addition, queries that contained a medical symptom or condition or a synonym thereof were analyzed. We identified medical symptoms and conditions that predicted searches for seeking treatment at different time lags. Specifically, symptom queries were first determined to be significantly predictive of subsequent 12-step queries if the probability of querying a medical symptom by those who later sought information about the 12-step program exceeded the probability of that same query being made by a comparison group of all other Bing users in the United States. Second, we examined symptom queries preceding queries on the 12-step program at time lags of 0-7 days, 7-14 days, and 14-30 days, where the probability of asking about a medical symptom was greater in the 30-day time window preceding 12-step program information-seeking as compared to all previous times that the symptom was queried.

Results

In our sample of 11,784 persons, we found 10 medical symptoms that predicted AA information seeking and 9 symptoms that predicted NA information seeking. Of these symptoms, a substantial number could be categorized as nonsevere in nature. Moreover, when medical symptom persistence was examined across a 1-month time period, a substantial number of nonsevere, yet persistent, symptoms were identified.

Conclusions

Our results suggest that many common or nonsevere medical symptoms and conditions motivate subsequent interest in AA and NA programs. In addition to highlighting severe long-term consequences, brief interventions could be restructured to highlight how increasing substance misuse can worsen discomfort from common medical symptoms in the short term, as well as how these worsening symptoms could exacerbate social embarrassment or decrease physical attractiveness.

The Association Between Ethnic Identity and Non-Medical Prescription Drug Use Among A Sample of College Students: Does a Sense of Ethnic Belonging Matter?

BACKGROUND

National data demonstrate significant differences in non-medical prescription drug (NMPD) use, with Whites seeming to be more likely to use compared to non-Whites. College students also appear to be at an increased risk for NMPD use.

OBJECTIVES

This study examines NMPD use using a component of social identity theory. We propose that a stronger sense of ethnic identity may reduce the likelihood of NMPD use among college students due to ethnic identity's ties to self-esteem and self-efficacy. We also propose that the protective power of ethnic identity may vary according to one's race.

METHODS

Data for this study were collected from a survey of undergraduate students at a Midwestern university (N = 530). Poisson regression analyses were used to test the relationship between ethnic identity and NMPD use. Of our sample, 135 participants (25.5%) indicated NMPD use over the past year. This percentage is high compared to findings from national college data.

RESULTS

Results indicate that a stronger sense of ethnic identity reduced the frequency of NMPD use among young adults. The findings also reveal that the relationship between ethnic identity and NMPD use is moderated by race. Ethnic identity was found to be a protective factor for non-White participants only.

CONCLUSIONS

This study suggests that ethnic belonging may act as a protective factor against NMPD use among non-White young adults. These findings build upon our understanding of the relationship between ethnic identity and substance use. We conclude with a discussion of directions for future research and intervention programs.

Non-medical use of prescription drugs and cultural orientation among college students in China

BACKGROUND

Due to a dramatic increase in the past 20 years, the non-medical use of prescription drugs (NMUPD) has become a global public health issue. College students have high prevalence of NMUPD in the United States. However, limited studies have been conducted among Chinese students. The purposes of this study were to examine the prevalence of NMUPD among college students in two urban centers (Beijing and Macau) in China and assess its relationships with cultural orientation (collectivism - primary focus on the group and individualism - primary focus on the individual).

METHODS

In January-April 2017, 849 undergraduates (72.2% female) from Beijing and Macau, with an average age of 20 completed online surveys about their demographics, NMUPD, and cultural orientation.

RESULTS

Overall, 62.9% (lifetime) and 33.4% (past three-months) of students in Beijing reported NMUPD, while 35.9% (lifetime) and 21.8% (past three-months) of students in Macau reported NMUPD. The most commonly non-medically used class of medicine (lifetime) was analgesics (62.9% Beijing; 35.5% Macau), followed by sedatives (4.0% Beijing; 0.9% Macau), anxiolytics (2.7% Beijing; 0.6% Macau), and stimulants (1.0% Beijing; 0.2% Macau). Multivariate analyses suggested a positive association of individualism with lifetime NMUPD (OR = 1.78, 95% CI = 1.15, 2.75, p < .01 in Beijing; OR = 1.53, 95% CI = 1.16, 2.02, p < .01 in Macau).

CONCLUSION

NMUPD in Chinese college students appears to be common. More discussion is needed in China about regulation of prescription drugs. Future culturally-tailored NMUPD-risk reduction intervention programs may be beneficial to Chinese college students.

The Effectiveness of Internet- and Field-Based Methods to Recruit Young Adults Who Use Prescription Opioids Nonmedically

BACKGROUND

Nonmedical prescription opioid (NMPO) use is a problem among young adults, yet young NMPO users are a diverse population that has been challenging to engage in overdose prevention and harm reduction programs.

OBJECTIVES

This study compared the effectiveness and characteristics of persons recruited through two different sampling strategies to inform research and intervention efforts with young adult NMPO users.

METHODS

We analyzed data from the Rhode Island Young Adult Prescription Drug Study (RAPiDS), which enrolled persons aged 18 to 29 who reported past 30-day NMPO use. We compared the characteristics of two samples recruited simultaneously between February 2015 and February 2016. One sample was recruited using field-based strategies (e.g., respondent-driven sampling, transit ads), and a second from internet sources (e.g., online classifieds).

RESULTS

Among 198 eligible participants, the median age was 25 (IQR: 22, 27), 130 (65.7%) were male, 123 (63.1%) were white, and 150 (78.1%) resided in urban areas. A total of 79 (39.9%) were recruited using field-based strategies and 119 (60.1%) were recruited from internet sources. Internet-recruited persons were younger (median = 24 [IQR: 21, 27] vs. 26 [IQR: 23, 28] years) and more likely to reside in rural areas (16.2% vs. 5.3%), although this finding was marginally significant. Field-recruited participants were more likely to have been homeless (36.7% vs. 17.7%), have been incarcerated (39.7% vs. 21.8%), and engage in daily NMPO use (34.6% vs. 14.5%).

CONCLUSIONS

Multipronged outreach methods are needed to engage the full spectrum of young adult NMPO users in prevention and harm reduction efforts.

Young Drug Users: a Vulnerable Population and an Underutilized Resource in HIV/HCV Prevention

PURPOSE OF REVIEW

The social networks of people who inject drugs (PWID) have long been studied to understand disease transmission dynamics and social influences on risky practices. We illustrate how PWID can be active agents promoting HIV, HCV, and overdose prevention.

RECENT FINDINGS

We assessed drug users' connections and interactions with others at risk for HIV/HCV in three cities: New York City (NYC), USA (n = 539); Pereira, Colombia (n = 50); and St. Petersburg, Russia (n = 49). In all three cities, the majority of participants' network members were of a similar age as themselves, yet connections across age groups were also present. In NYC, knowing any opioid user(s) older than 29 was associated with testing HCV-positive. In NYC and St. Petersburg, a large proportion of PWID engaged in intravention activities to support safer injection and overdose prevention; in Pereira, PWID injected, had sex, and interacted with other key groups at risk. People who use drugs can be active players in HIV/HCV and overdose risk- reduction; their networks provide them with ample opportunities to disseminate harm reduction knowledge, strategies, and norms to others at risk. Local communities could augment prevention programming by empowering drug users to be allies in the fight against HIV and facilitating their pre-existing health-protective actions.

Persistence/recurrence of and remission from DSM-5 substance use disorders in the United States: Substance-specific and substance-aggregated correlates

This study examined demographic and psychosocial correlates associated with persistence/recurrence of and remission from at least one of ten DSM-5 substance use disorders (SUDs) and three substance-specific SUDs (i.e., alcohol, cannabis, and prescription opioids). Data were collected from structured diagnostic interviews and national prevalence estimates were derived from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions. An estimated 25.4% of the U.S. population had at least one prior-to-past-year (prior) SUD. Among individuals with any prior SUDs, the prevalence of past-year substance use and DSM-5 symptomology was as follows: abstinence (14.2%), asymptomatic use (36.9%), symptomatic use (10.9%), and persistent/recurrent SUD (38.1%). Among individuals with prior SUDs, design-based multinomial logistic regression analysis revealed that young adulthood, higher educational attainment, higher personal income, never having been married, being divorced/separated/widowed, lack of lifetime substance use treatment, and stressful life events predicted significantly greater odds of past-year persistent/recurrent SUDs, relative to abstinence. In addition, remission from a prior tobacco use disorder decreased the probability of past-year persistent/recurrent SUD, relative to abstinence. Stressful life events were the only common correlates across the aggregation of all SUDs and each substance-specific SUD, but differences were found for specific stressful life events between drug classes. Nearly half (49%) of adults with prior DSM-5 SUDs continued to report past-year symptomatic substance use, while only one in seven individuals were abstinent. The findings suggest the value of examining remission associated with both substance-specific SUDs and aggregation of SUDs based on the shared and unique correlates of persistent/recurrent SUDs; this is especially true for stressful life events, which could be useful targets for enhancing clinical care and interventions.

Rural and Urban Differences in Nebraskans’ Access to Marijuana, Methamphetamine, Heroin, and Prescription Pills

The ability of a user to access a given type of drug is related to the configuration of the market for that drug, and a range of economic and criminal justice concerns. This study focuses on Nebraskan’s “ready access” to four types of drugs (marijuana, methamphetamine, heroin, and prescription pills) in 2016, using a statewide survey of housed Nebraskan adults. Ready access is defined as a participant knowing at least one person from whom they could obtain a given type of drug if they wanted to. We found that 35% of adult Nebraskans knew at least one person from whom they could obtain marijuana, 8.9% for methamphetamine, 4.5% for heroin, and 17.8% knew at least one source for prescription pills. Relationships between knowing a source for each type of drug and rurality, sex, race, religious attendance, mental health symptoms, and education are explored.

Prevalence and Factors Associated with Multiple Provider Episodes in Texas: An Epidemiological Analysis of Prescription Drug Monitoring Program Data

Objective

Prescription drug abuse has reached epidemic levels, leading to overdose-related morbidity and mortality. Patient and regional-level factors are believed to contribute to higher rates of prescription drug abuse. The objective of this study was to determine the prevalence and factors associated with multiple provider episodes (MPEs) in Texas.

Methods

This was a retrospective cohort analysis of data from the Texas Prescription Drug Monitoring Program (PDMP) database, linked with Texas county census data. Descriptive statistics and a multilevel model regression analysis were employed to estimate the prevalence of MPEs and examine the association between individual controlled substance prescription (CSP) utilization and county factors associated with MPEs.

Results

Among the 10,381,532 Texas residents utilizing CSPs in 2013, prescription opioids were the most frequently dispensed CSP (38.64%). The prevalence of MPEs was 71.30 per population of 100,000. Of those with MPEs, 76.98% received CSPs for more than 150 days and 11.48% had an average daily morphine equivalent dose (MED) 100 mg/day or higher. Residing in metropolitan areas, traveling more than 100 miles to obtain and fill prescriptions, chronic use of CSPs, younger age, and high MED were all significantly associated with increased risk of MPEs.

Conclusions

This study revealed that previous estimates of prescription drug abuse may be drastically underestimated. Prescription drug abuse is a major public health problem in Texas, especially in metropolitan areas. Therefore, prevention efforts need to be addressed at the individual level and through public health and policy legislation.

Risk of amphetamine use disorder and mortality among incident users of prescribed stimulant medications in the Veterans Administration

BACKGROUND AND AIMS

Non-medical use of prescribed stimulant medications is a growing concern. This study's aims were to ascertain the demographics of stimulant medication users compared with non-users, examine temporal trends of stimulant medication use and estimate risk factors for development of amphetamine use disorder (AUD) and mortality among new users of stimulant medications.

DESIGN

Cox proportional hazards regression in a retrospective cohort adjusted by baseline covariates.

SETTING

United States, national administrative database of the Veterans Affairs (VA) health-care system.

PARTICIPANTS

Adult incident users of stimulant medications (n = 78 829) from fiscal years (FY) 2001 to 2012.

MEASUREMENTS

Primary outcomes were time-to-event: (1) occurrence of AUD diagnosis and (2) death. Baseline covariates included demographic information, Food and Drug Administration (FDA)-approved indications for stimulant use, substance use disorders (SUD) and depression.

FINDINGS

Stimulant users compared with non-users were younger, more likely to be non-Hispanic white and female. Incident stimulant medication users increased threefold from FY2001-FY2012 and eightfold among adults aged 18-44 years. Nearly one in 10 incident users in FY2012 had a comorbid baseline SUD. Off-label use was common-nearly three of every five incident users in FY2012. Comorbid SUDs among incident stimulant medication users were risk factors for occurrence of AUD during follow-up, with adjusted hazard ratio (AHR) estimates ranging from 1.54 to 2.83 (Ps < 0.05). Increased mortality risk was observed with occurrence of AUD during follow-up [AHR = 1.55, 95% confidence interval (CI) = 1.13-2.14, P = 0.007], while on-label prescribing was protective against death (AHR = 0.686, 95% CI = 0.63-0.75, P < 0.0001).

CONCLUSIONS

In a US national cohort of adult incident stimulant medication users in the Veterans Affairs health-care system, measured from fiscal years 2001 to 2012, comorbid substance use disorders were common and were risk factors for development of an amphetamine use disorder (AUD). Increased mortality risk among incident users of stimulant medications was observed among both those who developed an AUD later and those whose use was defined as off-label.

Nonmedical prescription drug use among African Americans who use MDMA (ecstasy/molly): Implications for risk reduction

Recent data suggest that both nonmedical prescription drug and MDMA (ecstasy/molly) use have risen among African Americans. However, studies investigating these two forms of drug use among African Americans are rare. As a result, very little is known about African-American MDMA users and their nonmedical use of prescription medications. The primary goal of this study, therefore, was to describe patterns of nonmedical prescription drug use among African Americans who use MDMA. We also assessed alcohol and illicit drug use among the sample. Surveys (n=100) and in-depth interviews (n=15) were conducted with African-American young adults in Southwest Florida between August 2014 and November 2015. Survey results show that a significant proportion of the sample used MDMA in conjunction with prescription medications (benzodiazepines=59%; opioids=35%; stimulants=13%). Qualitative findings suggest that benzodiazepine medications were used to alleviate MDMA comedown symptoms, opioids were used to achieve a different quality high, and stimulants were used to provide added energy throughout the night. These results suggest that treatment practitioners and harm reduction professionals should pay particular attention to informing users of the potential hazards of combining MDMA with prescription medications. Although additional research is clearly needed, these findings are an important first step towards understanding both nonmedical prescription drug and MDMA use among African Americans, and could be used to tailor treatment and risk reduction interventions to this population.

Opioid Misuse Trends in Treatment Seeking Populations: Revised Prescription Opioid Policy and Temporally Corresponding Changes

BACKGROUND

Over the last two decades, U.S. rates of prescription opioid (PO) misuse have risen drastically. In response, federal and state governments have begun to implement new PO policies. Recent legislative changes warrant up-to-date assessments of today's misuse rates.

OBJECTIVE

To explore potential changes in opioid misuse trends among substance-using treatment seekers, in temporal relation to legislative response.

METHODS

Substance-use data were collected from two cross-sectional Florida-based inpatient cohorts during periods preceding (pre-policy; n = 647) and following (post-policy; n = 396) statewide PO policy initiatives. Participants provided information concerning their most frequently used drugs before treatment. PO and illicit opioid (IO) use prevalence, frequency and route of administration were examined for pre-policy vs. post-policy cohort differences.

RESULTS

Relative to the pre-policy cohort, a greater percentage of the post-policy cohort reported recent misuse, daily use, and intravenous administration of POs. IO use was also more frequently reported post-policy. Non-opioid drug use prevalence did not significantly differ between cohorts. Among the opioid-using subsample, equivalent percentages of the pre- and post-policy cohorts reported the use of POs without IOs, IOs without POs, and POs/IOs concurrently. Conclusions/Importance: Florida's PO policy amendments were temporally accompanied by a higher prevalence of PO misuse and IO use among treatment-seekers assessed in this study. Whether our data reflect increased awareness of and treatment seeking for opioid use disorders or insufficient efficacy of new policies to reduce opioid misuse remains in question. Regardless, findings suggest the need for enhanced emphasis on mitigating hazardous PO-use behaviors (e.g., IV use).

Multiple DSM-5 substance use disorders: A national study of US adults

OBJECTIVE

Our aim is to determine the lifetime and past-year prevalence estimates of multiple Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) substance use disorders (SUDs) among U.S. adults.

METHODS

The 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions featured in-person interviews with a nationally representative sample of adults aged 18 and older.

RESULTS

The majority of past-year nonalcohol DSM-5 SUDs had at least 1 other co-occurring past-year SUD, ranging from 56.8% (SE = 3.4) for past-year prescription opioid use disorder to 97.5% (SE = 2.7) for past-year hallucinogen use disorder. In contrast, only 15.0% (SE = 0.6) of past-year alcohol use disorders had a co-occurring past-year SUD. The odds of past-year multiple SUDs were greater among males, younger adults, African-Americans, and those with mood, personality, posttraumatic stress, or multiple psychiatric disorders.

CONCLUSIONS

Assessment, diagnosis, and treatment often focus on individual substance-specific SUDs rather than multiple SUDs, despite evidence for substantial rates of polysubstance use in clinical and epidemiological studies. There are notable differences in the prevalence of multiple SUDs between alcohol use disorders and other nonalcohol SUDs that have important clinical implications; for example, multiple SUDs are more persistent than individual SUDs. These findings suggest that clinical assessment and diagnosis should screen for multiple SUDs, especially among adults with nonalcohol DSM-5 SUDs.

Substance dependence among those without symptoms of substance abuse in the World Mental Health Survey

The World Health Organization (WHO) World Mental Health (WMH) Survey Initiative uses the Composite International Diagnostic Interview (CIDI). The first 13 surveys only assessed substance dependence among respondents with a history of substance abuse; later surveys also assessed substance dependence without symptoms of abuse. We compared results across the two sets of surveys to assess implications of the revised logic and develop an imputation model for missing values of lifetime dependence in the earlier surveys. Lifetime dependence without symptoms of abuse was low in the second set of surveys (0.3% alcohol, 0.2% drugs). Regression-based imputation models were built in random half-samples of the new surveys and validated in the other half. There were minimal differences for imputed and actual reported cases in the validation dataset for age, gender and quantity; more mental disorders and days out of role were found in the imputed cases. Concordance between imputed and observed dependence cases in the full sample was high for alcohol [sensitivity 88.0%, specificity 99.8%, total classification accuracy (TCA) 99.5%, area under the curve (AUC) 0.94] and drug dependence (sensitivity 100.0%, specificity 99.8%, TCA 99.8%, AUC 1.00). This provides cross-national evidence of the small degree to which lifetime dependence occurs without symptoms of abuse. Imputation of substance dependence in the earlier WMH surveys improved estimates of dependence.

Illicit drug use is increasing among non-medical users of prescription drugs-Results from population-based surveys 2002-2014

BACKGROUND

Non-medical use of prescription drugs (NMUPD) is known to be associated with illicit drug use, but less is known about how illicit drug use has changed in NMUPD. We examined (1) the changes in illicit drug use among Finnish non-medical users of prescription drugs during the 2000s and (2) whether the trends of illicit drug use differ by non-medical use of prescription drugs in the general population.

METHODS

Data were derived from population-based (aged 15-69) Drug Surveys conducted in Finland in 2002, 2006, 2010 and 2014. The response rates varied between 63% and 48%. NMUPD during the last year was measured (n=252). Past-year illicit drug use among non-medical users of prescription drugs and the reference population not reporting NMUPD (n=10,967) was compared. Logistic regression was used to estimate the p-values for trends.

RESULTS

Illicit drug use has increased notably among Finnish non-medical users of prescription drugs (from 21% to 70%, p for trend<0.001). This was not explained by the respondents' gender, age, employment status or alcohol use. Among the reference population, illicit drug use also increased statistically significantly, but much more moderately (from 2.5% to 5.4%). The difference between the trends was confirmed by an interaction test (p=0.022).

CONCLUSIONS

NMUPD seems to be increasingly merging with illicit drug use. This indicates an increasing prevalence of polydrug use among non-medical users of prescription drugs, which may bring about more severe harms and worse health outcomes for users and more challenges in regard to treatment.

Alcohol and Nonmedical Prescription Drug Use to Cope With Posttraumatic Stress Disorder Symptoms: An Analysis of Hurricane Sandy Survivors

BACKGROUND

Postdisaster increases in substance use have been attributed to use of substances to cope with emotional reactions. However, no study to our knowledge has explored disaster survivors' substance use to cope with posttraumatic stress disorder (PTSD) symptoms.

OBJECTIVE

We investigated the prevalence and correlates of alcohol use and nonmedical prescription drug use (NMPDU) to cope with PTSD symptoms in two population-based samples of adult residents of New York City neighborhoods affected by Hurricane Sandy.

METHOD

Participants completed structured interviews at either 13-16 or 25-28 months postdisaster (combined N = 914). Participants with PTSD symptoms, assessed via the Posttraumatic Stress Checklist for DSM-5, indicated whether they coped with their symptoms through alcohol use or NMPDU, via items adapted from the National Epidemiologic Survey on Alcohol and Related Conditions. Logistic regression models explored correlates of substance use coping, including demographic characteristics, lifetime and hurricane-related exposures, and psychiatric symptoms in the combined sample.

RESULTS

Over a third of participants in the combined sample (n = 311, 34.0%) reported PTSD symptoms, and of these, 12.8% used alcohol to cope and 9.2% endorsed NMPDU to cope. Older age and being a parent living with a child under 18 years old at the time of the hurricane were associated with a lower likelihood, and more severe depression symptoms with a higher likelihood, of alcohol use coping. Conclusions/Importance: Although preliminary, the results provide evidence for the use of substances to cope with postdisaster PTSD symptoms, and that age, parent status, and depression symptoms are associated with alcohol use coping.

The 3-Year Course of Multiple Substance Use Disorders in the United States: A National Longitudinal Study

OBJECTIVE

To examine the 3-year course of multiple co-occurring substance use disorders (SUDs) based on longitudinal survey data from a large, nationally representative sample.

METHODS

National estimates of the prevalence of DSM-IV SUDs were derived by analyzing data from structured, face-to-face diagnostic interviews as part of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), which collected data from a large, nationally representative sample of noninstitutionalized US adults at 2 waves (2001-2002 and 2004-2005; N = 34,653).

RESULTS

US adults with multiple past-year SUDs at Wave 1 were substantially more likely than those with an individual past-year SUD or no SUD at Wave 1 to report at least 1 past-year SUD at Wave 2 (66.3% vs 46.0% vs 6.9%, respectively). There were several sociodemographic characteristics and psychiatric disorders (ie, male, younger age, never married, sexual minority identity, nicotine dependence, mood disorder, and personality disorder) associated with increased odds of developing multiple SUDs and having 3-year persistence of multiple SUDs. The majority of adults with multiple past-year SUDs had a lifetime personality disorder and did not utilize substance abuse treatment or other help-seeking.

CONCLUSIONS

Multiple SUDs are associated with a more persistent 3-year course of disease over time relative to individual SUDs. Despite a more severe 3-year course and higher rates of comorbidity with other psychiatric disorders, the majority of US adults with multiple SUDs do not utilize substance abuse treatment or other help-seeking. Clinical assessments and the substance abuse literature tend to focus on drug-specific individual SUDs rather than considering the more complex multiple SUDs, which can be more challenging to treat.

The association of psychedelic use and opioid use disorders among illicit users in the United States

BACKGROUND

Preliminary studies show psychedelic compounds administered with psychotherapy are potentially effective and durable substance misuse interventions. However, little is known about the association between psychedelic use and substance misuse in the general population. This study investigated the association between psychedelic use and past year opioid use disorders within illicit opioid users.

METHODS

While controlling for socio-demographic covariates and the use of other substances, the relationship between classic psychedelic use and past year opioid use disorders was analyzed within 44,000 illicit opioid users who completed the National Survey on Drug Use and Health from 2008 to 2013.

RESULTS

Among respondents with a history of illicit opioid use, psychedelic drug use is associated with 27% reduced risk of past year opioid dependence (weighted risk ratio = 0.73 (0.60-0.89) p = 0.002) and 40% reduced risk of past year opioid abuse (weighted risk ratio = 0.60 (0.41-0.86) p = 0.006). Other than marijuana use, which was associated with 55% reduced risk of past year opioid abuse (weighted risk ratio = 0.45 (0.30-0.66) p < 0.001), no other illicit drug was associated with reduced risk of past year opioid dependence or abuse.

CONCLUSION

Experience with psychedelic drugs is associated with decreased risk of opioid abuse and dependence. Conversely, other illicit drug use history is largely associated with increased risk of opioid abuse and dependence. These findings suggest that psychedelics are associated with positive psychological characteristics and are consistent with prior reports suggesting efficacy in treatment of substance use disorders.

Motives for Prescription Stimulant Misuse in a College Sample: Characteristics of Users, Perception of Risk, and Consequences of Use

BACKGROUND

Prescription stimulant misuse is increasingly prevalent in college populations, with some misuse estimates over 40%. Stimulant use is associated with a variety of health and psychological problems. Motives for use may provide insight into problematic trajectories.

OBJECTIVES

The purpose of the current study was to evaluate characteristics of users and motives for prescription stimulant misuse in a large southeastern university.

METHOD

College students reported on prescription stimulant use, motives for use, consequences associated with use, perceptions of risk, and social norms. We specifically elicited participation from prescription stimulant misusers. Of the 199 participants, 86 reported misusing prescription stimulants in the past 60 days. We assessed motives for use, rates of substance use, risk perception, normative beliefs, and consequences associated with use. We evaluated differences between misusers and non-misusers, differentiate motives subscales, and identify relationships between motives subscales, rates of use, and consequences.

RESULTS

Misusers used more alcohol and other drugs, held different normative beliefs regarding stimulants, and had lower risk perceptions than non-misusers. We evaluated seven motives subscales among misusers: coping, social, enhancement, expansion, conformity, academic performance, and weight loss. Enhancement, social, weight loss, and expansion scales were correlated with negative consequences, while social motives were correlated with use. Results from regression analyses revealed positive associations between weight and expansion with negative consequences, and a negative association between conformity and consequences. Conclusions/Importance:Motives for prescription stimulant use and user characteristics may provide insight into prevention and treatment. Continued work is needed to refine item content and replicate findings.

Mothers Who abuse Alcohol and Drugs: Health and Social Harms among Substance-Abusing Mothers of Small Children in three Child Cohorts

AIMS – The study looks at the prevalence and register-based indicators of substance abuse-related harms among mothers of small children. We examined the living conditions, various health and social harms and the differences between the users of different kinds of substances (alcohol only vs. drugs only vs. alcohol and other drugs). DATA & METHODS – Population-level register data was collected of all biological mothers of three Finnish birth cohorts (1991, 1997, 2002) describing the women's social problems, health and use of services during the period when the child was under seven years old. RESULTS – The substance-abusing mothers of small children had a higher rate of mortality and psychological disorders and increased risk of using hospital services than the comparison group. Their children had been taken into custody dramatically more often than the children of the comparison group. Also, mothers with substance abuse problems had lower education and income level, and their purchases of prescribed psychopharmacological medications were manifold compared to other mothers. Mixed use of both alcohol and illegal drugs coincided with the highest prevalence of health and social problems. CONCLUSIONS – Substance-abusing mothers of small children are in a serious risk of health and social problems ranging from poverty to poor mental health and high mortality. The study shows also that the social and health care professionals have a potentially important role in giving support to the mothers and their children, as the substance-abusing mothers have had several contacts with them. Prevention of harms to children of substance-abusing mothers should perhaps focus more on the possibilities offered by these contacts in different health and social services.

The risks of opioid treatment: Perspectives of primary care practitioners and patients from safety-net clinics

BACKGROUND

Patients with a history of substance use are more likely than those without substance use to experience chronic noncancer pain (CNCP), to be prescribed opioids, and to experience opioid misuse or overdose. Primary care practitioners (PCPs) in safety-net settings care for low-income patients with CNCP and substance use, usually without specialist consultation. To inform communication related to opioid risk, we explored PCPs' and patients' perceptions of the risks of chronic opioid therapy.

METHODS

We conducted semistructured interviews with 23 PCPs and 46 of their patients, who had a history of CNCP and substance use. We recruited from 6 safety-net health care settings in the San Francisco Bay Area. We transcribed interviews verbatim and analyzed transcripts using grounded theory methodology.

RESULTS

(1) PCPs feared harming patients and the community by opioid prescribing. PCPs emphasized fear of opioid overdose. (2) Patients did not highlight concerns about the adverse health consequences of opioids, except for addiction. (3) Both patients and PCPs were concerned about PCPs' medicolegal risks related to opioid prescribing. (4) Patients reported feeling stigmatized by policies aimed at reducing opioid misuse.

CONCLUSION

We identified differences in how clinicians and patients perceive opioid risk. To improve the informed consent process for opioid therapy, patients and PCPs need to have a shared understanding of the risks of opioids and engage in discussions that promote patient autonomy and safety. As clinics implement opioid prescribing policies, clinicians must develop effective communication strategies in order to educate patients about opioid risks and decrease patients' experiences of stigma and discrimination.

Understanding the demand side of the prescription opioid epidemic: Does the initial source of opioids matter?

BACKGROUND

These studies were carried out to examine whether the onset and progression of an opioid substance use disorder (SUD) differed in those who first used opioids to get "high" compared to those who received a prescription from a doctor to relieve pain (Non-Rx vs. Rx groups, respectively).

METHODS

A subset of patients (N=214) from an ongoing larger study of patients entering one of 125 drug treatment programs for opioid use disorder across the country agreed to give up their anonymity and participate in structured and open-ended online interviews examining drug abuse patterns.

RESULTS

With the exception that the Non-Rx group began their opioid abuse at a younger age than the Rx group and more quickly evolved from initial exposure to regular opioid abuse, there were relatively few differences in the characteristics, patterns and trajectories of opioid abuse. The vast majority of patients in both groups, most of whom had serious, antecedent psychiatric disorders, indicated that they used opioids to self-medicate psychological problems (67-73%) and/or stated that opioids provided a means to "escape" from the stresses of everyday life (79-85%). As the SUD progressed, for many individuals any "positive" attributes of opioids waned and avoidance of withdrawal became the overriding concern, often serving as the impetus for treatment.

CONCLUSIONS

Our results suggest that self-treatment of co-morbid psychiatric disturbances is a powerful motivating force to initiate and sustain abuse of opioids and that the initial source of drugs-a prescription or experimentation-is largely irrelevant in the progression to a SUD.

Nonmedical Prescription Stimulant Use Among Girls 10-18 Years of Age: Associations With Other Risky Behavior

PURPOSE

Little is known about the risk factors for nonmedical use (NMU) of prescription stimulants among adolescent girls. We aimed to measure the association of nonmedical prescription stimulant use with empirically linked risk factors, including weight control behavior (WCB), gambling, and depressed mood, in pre-teen and teenaged girls.

METHODS

We assessed the relationship between age and race, gambling, WCB, depressive mood, and nonmedical prescription stimulant use using multivariable logistic regression. The study sample included 5,585 females, aged 10-18 years, recruited via an entertainment venue intercept method in 10 U.S. metropolitan areas as part of the National Monitoring of Adolescent Prescription Stimulants Study (2008-2011).

RESULTS

NMU of prescription stimulants was reported by 6.6% (n = 370) of the sample. In multivariable logistic regression, 1-year increase in age was associated with a 21% (95% confidence interval [CI]: .15, .28) increase in risk for NMU. Whites and other race/ethnicity girls had 2.67 (CI: 1.85, 3.87) and 1.71 (1.11, 2.65) times higher odds for NMU, compared to African-Americans. Depressive mood (adjusted odds ratio: 2.69, CI: 2.04, 5.57) and gambling (adjusted odds ratio: 1.90, 1.23, 2.92) were associated with increased odds for NMU. A dose-response was identified between WCB and NMU, where girls with unhealthy and extreme WCB were over five times more likely to endorse NMU.

CONCLUSIONS

We contribute to the literature linking WCB, depression, gambling, and the NMU of prescription stimulants in any population and uniquely do so among girls.

Daily sleep quality affects drug craving, partially through indirect associations with positive affect, in patients in treatment for nonmedical use of prescription drugs

OBJECTIVE

Sleep disturbance has been identified as a risk factor for relapse in addiction to a range of substances. The relationship between sleep quality and treatment outcome has received relatively little attention in research on nonmedical use of prescription drugs (NMUPD). This study examined the within-person association between sleep quality and craving in medically detoxified patients in residence for the treatment of NMUPD.

METHOD

Participants (n=68) provided daily reports of their sleep quality, negative affect (NA), positive affect (PA), and craving for an average of 9.36 (SD=2.99) days. Within-person associations of sleep quality and craving were examined using multilevel modeling. Within-person mediation analyses were used to evaluate the mediating roles of NA and PA in the relationship between sleep quality and craving.

RESULTS

Greater cravings were observed on days of lower than usual sleep quality (γ₁₀=-0.10, p=0.003). Thirty-one percent of the overall association between sleep quality and craving was explained by PA, such that poorer sleep quality was associated with lower PA and, in turn, lower PA was associated with greater craving. No evidence emerged for an indirect association between sleep quality and craving through NA.

CONCLUSIONS

Daily fluctuations in sleep quality were associated with fluctuations in craving, an association partially explained by the association between sleep quality and daily PA. These data encourage further research on the relationship between sleep, affect, and craving in NMUPD patients, as well as in patients with other substance use disorders.

An Assessment of the Impact of a Multipronged Approach to Reducing Problematic Pain Clinics in Florida

The present research evaluates recent changes to Florida law and policy to reduce problematic pain clinics (pill mills) and criminal diversion of prescription opioids. These changes entailed a multipronged effort linking regulatory and criminal-law approaches. Quantitative data from the Florida Department of Health and qualitative data from in-depth interviews with law-enforcement officers assigned to pill-mill taskforces reveal steep declines in pain clinics and pill mills. Respondents credit some regulatory enhancements for the reduction, although they describe some interagency cooperation problems and emphasize that despite success, many troublesome establishments continue to operate. The results suggest that Florida’s effort to reduce opioid diversion by tightening regulatory restrictions and law-enforcement scrutiny illustrates a multiagency approach to a problem spanning public health and criminal justice. This could be an example for other states seeking to combat problems that cannot be effectively addressed using regulatory or criminal law alone.

Developmental course of non-medical use of prescription drugs from adolescence to adulthood in the United States: national longitudinal data

AIMS

To identify the developmental course of non-medical use of four separate prescription drug classes (opioids, sedatives, stimulants and tranquilizers) by examining the general functional growth and related covariates during the transition from adolescence to adulthood in the United States.

DESIGN

Nationally representative probability samples of high school seniors were followed longitudinally across five waves (waves 1, 2, 3, 4 and 5: modal ages 18, 19/20, 21/22, 23/24 and 25/26 years, respectively).

SETTING

Data were collected via self-administered questionnaires to high school seniors and young adults in the United States.

PARTICIPANTS

The sample consisted of nearly 72 000 individuals in 30 cohorts (high school senior years of 1977-2006) who participated in at least one wave.

MEASUREMENTS

Self-reports of annual non-medical use of prescription opioids, sedatives, stimulants, and tranquilizers.

FINDINGS

The annual non-medical use of prescription opioids, sedatives, stimulants and tranquilizers was highest at wave 1 over the five waves. There was a consistent descending path (linear and quadratic slopes, P < 0.001) in annual non-medical use from baseline across all four prescription drug classes (e.g. opioids linear slope = -0.043 and opioids quadratic slope = 0.034, P < 0.001). While the annual non-medical use of stimulants declined over time (linear slope = 0.063, P < 0.01; quadratic slope = -0.133, P < 0.001), the same decrease was not observed for the annual non-medical use of prescription opioids, sedatives or tranquilizers when controlling for socio-demographic and substance use behaviors at baseline. The covariates associated with the general functional growth differed across the four prescription drug classes.

CONCLUSIONS

The non-medical use of prescription opioids, sedatives, stimulants and tranquilizers appears to peak during late adolescence, suggesting preventive intervention efforts should be initiated in early adolescence. The developmental course of non-medical use is not the same among all four classes of prescription drugs, suggesting that each drug class warrants individual research.

Interviewing and Urine Drug Toxicology Screening in a Pediatric Pain Management Center: An Analysis of Analgesic Nonadherence and Aberrant Behaviors in Adolescents and Young Adults

OBJECTIVES

Many adolescents and young adults report having chronic pain. Urine drug toxicology (UDT) is not routinely used in the pediatric pain management population, despite more routine use in adults with pain, particularly those prescribed opioids. As a first step toward establishing monitoring practices in pediatric and adolescent pain management, the present study evaluated the role of UDT in conjunction with a standard clinical interview in identifying the rate of adherence to an established analgesic regimen. The study also aimed to assess the use of UDT in identifying possible aberrant behaviors in this population.

METHODS

Data were acquired from a convenience sample of 50 pediatric and adolescent pain management initial consultations, during which a clinical interview and UDT were conducted. Data were analyzed to determine adherence to an established analgesic prescription regimen, and for identification of aberrant behaviors including concurrent use of illicit substances and prescription medication misuse. Other pertinent demographic and clinical factors were examined as factors in adherence.

RESULTS

Opioid medications were prescribed for 42% of the sample receiving pain medications, and 22% of the sample was nonadherent to their prescription analgesic regimen. Factors associated with a higher likelihood of nonadherence were an older age and having an opioid prescription. The majority (90%) of those nonadherent to their analgesic regimen displayed some form of aberrant behavior. Among the nonadherent patients, 50% were identified by UDT alone, and 50% were identified by self-report during the clinical encounter.

CONCLUSIONS

These results highlight the challenges of identifying nonadherence to a prescription regimen among adolescents with chronic pain. In addition, this preliminary work suggests that UDT could be used in conjunction with careful clinical interviewing to substantiate patient report and increase the likelihood of detecting analgesic nonadherence and aberrant behaviors.
