America's opioid crisis: the need for an integrated public health approach

Using Photovoice to Improve Engagement in Community Health Assessments Addressing Behavioral Health

Behavioral health disorders are well-known to have close links with the social determinants of health, yet little is known about how impacted communities perceive these links. Qualitative participatory methods can not only provide insight into how communities conceptualize these relationships but also empower those with lived experience to contextualize their perspectives and formulate calls to action. This study used Photovoice as a participatory method to supplement the Clark County Health Department Community Health Assessment and determine priority facilitators and barriers contributing to the behavioral health of Clark County, KY, residents. A secondary aim was to gain a greater understanding of how the Photovoice methodology impacts community engagement efforts in Community Health Assessments. Twenty-three Clark County residents participated in four Photovoice groups involving five weekly sessions, which included photograph "show and tell," critical group dialogue, participatory analysis, and planning for dissemination. Secondary analysis of Photovoice focus group discussions revealed behavioral health facilitators and barriers were most influenced by (1) public sector unresponsiveness, (2) strong partnerships formed between community and grassroots organizations, and (3) the siloed division of responsibility between agencies and across sectors. The authors also found the Photovoice method successfully enhanced engagement and empowered those with lived experience to frame their perspectives of the behavioral health landscape. This project has implications for enhancing community engagement and empowerment in behavioral health-focused public health assessments and shaping policy to promote multi-sector collaboration.

Trauma exposure across the lifespan among individuals engaged in treatment with medication for opioid use disorder: differences by gender, PTSD status, and chronic pain

BACKGROUND

There is little study of lifetime trauma exposure among individuals engaged in medication treatment for opioid use disorder (MOUD). A multisite study provided the opportunity to examine the prevalence of lifetime trauma and differences by gender, PTSD status, and chronic pain.

METHODS

A cross-sectional study examined baseline data from participants (N = 303) enrolled in a randomized controlled trial of a mind-body intervention as an adjunct to MOUD. All participants were stabilized on MOUD. Measures included the Trauma Life Events Questionnaire (TLEQ), the Brief Pain Inventory (BPI), and the Posttraumatic Stress Disorder Checklist (PCL-5). Analyses involved descriptive statistics, independent sample t-tests, and linear and logistic regression.

RESULTS

Participants were self-identified as women (n = 157), men (n = 144), and non-binary (n = 2). Fifty-seven percent (n = 172) self-reported chronic pain, and 41% (n = 124) scored above the screening cut-off for PTSD. Women reported significantly more intimate partner violence (85%) vs 73%) and adult sexual assault (57% vs 13%), while men reported more physical assault (81% vs 61%) and witnessing trauma (66% vs 48%). Men and women experienced substantial childhood physical abuse, witnessed intimate partner violence as children, and reported an equivalent exposure to accidents as adults. The number of traumatic events predicted PTSD symptom severity and PTSD diagnostic status. Participants with chronic pain, compared to those without chronic pain, had significantly more traumatic events in childhood (85% vs 75%).

CONCLUSION

The study found a high prevalence of lifetime trauma among people in MOUD. Results highlight the need for comprehensive assessment and mental health services to address trauma among those in MOUD treatment.

Telling the story of the opioid crisis: A narrative analysis of the TV series Dopesick

Dopesick (2021) is the first TV series whose plot deals exclusively with the opioid crisis in the United States. The current study uses narrative analysis and framing theory to explore this series, discussing its portrayal of the people and themes involved in the opioid crisis. Our analysis found that although Dopesick attempts to portray multiple dimensions of the opioid crisis, its narrative oversimplifies the story in attributing the cause of the problem almost exclusively to Purdue Pharma and its director Richard Sackler, while downplaying other factors that contributed to the opioid crisis. Thus, the narrative in this TV series tends to offer simple explanations to a complex problem for which simple solutions are likely to be inadequate.

Public Health Interventions and Overdose-Related Outcomes Among Persons With Opioid Use Disorder

Importance

Given the high number of opioid overdose deaths in the US and the complex epidemiology of opioid use disorder (OUD), systems models can serve as a tool to identify opportunities for public health interventions.

Objective

To estimate the projected 3-year association between public health interventions and opioid overdose-related outcomes among persons with OUD.

Design, Setting, and Participants

This decision analytical model used a simulation model of the estimated US population aged 12 years and older with OUD that was developed and analyzed between January 2019 and December 2023. The model was parameterized and calibrated using 2019 to 2020 data and used to estimate the relative change in outcomes associated with simulated public health interventions implemented between 2021 and 2023.

Main Outcomes and Measures

Projected OUD and medications for OUD (MOUD) prevalence in 2023 and number of nonfatal and fatal opioid-involved overdoses among persons with OUD between 2021 and 2023.

Results

In a baseline scenario assuming parameters calibrated using 2019 to 2020 data remained constant, the model projected more than 16 million persons with OUD not receiving MOUD treatment and nearly 1.7 million persons receiving MOUD treatment in 2023. Additionally, the model projected over 5 million nonfatal and over 145 000 fatal opioid-involved overdoses among persons with OUD between 2021 and 2023. When simulating combinations of interventions that involved reducing overdose rates by 50%, the model projected decreases of up to 35.2% in nonfatal and 36.6% in fatal opioid-involved overdoses among persons with OUD. Interventions specific to persons with OUD not currently receiving MOUD treatment demonstrated the greatest reduction in numbers of nonfatal and fatal overdoses. Combinations of interventions that increased MOUD initiation and decreased OUD recurrence were projected to reduce OUD prevalence by up to 23.4%, increase MOUD prevalence by up to 137.1%, and reduce nonfatal and fatal opioid-involved overdoses among persons with OUD by 6.7% and 3.5%, respectively.

Conclusions and Relevance

In this decision analytical model study of persons with OUD, findings suggested that expansion of evidence-based interventions that directly reduce the risk of overdose fatality among persons with OUD, such as through harm reduction efforts, could engender the highest reductions in fatal overdoses in the short-term. Interventions aimed at increasing MOUD initiation and retention of persons in treatment projected considerable improvement in MOUD and OUD prevalence but could require a longer time horizon for substantial reductions in opioid-involved overdoses.

Opioid use in cancer patients compared with noncancer pain patients in a veteran population

BACKGROUND

Opioid safety initiatives may secondarily impact opioid prescribing and pain outcomes for cancer care.

METHODS

We reviewed electronic health record data at a tertiary Veterans Affairs system (VA Palo Alto) for all patients from 2015 to 2021. We collected outpatient Schedule II opioid prescriptions data and calculated morphine milligram equivalents (MMEs) using Centers for Disease Control and Prevention conversion formulas. To determine the clinical impact of changes in opioid prescription, we used the highest level of pain reported by each patient on the 0-to-10 Numeric Rating Scale in each year, categorized into mild (0-3), moderate (4-6), and severe (7 and above).

RESULTS

Among 89 569 patients, 9073 had a cancer diagnosis. Cancer patients were almost twice as likely to have an opioid prescription compared with noncancer patients (69.0% vs 36.7%, respectively). The proportion of patients who received an opioid prescription decreased from 27.1% to 18.1% (trend P < .01) in cancer patients and from 17.0% to 10.2% in noncancer patients (trend P < .01). Cancer and noncancer patients had similar declines of MMEs per year between 2015 and 2019, but the decline was more rapid for cancer patients (1462.5 to 946.4, 35.3%) compared with noncancer patients (1315.6 to 927.7, 29.5%) from 2019 to 2021. During the study period, the proportion of noncancer patients who experienced severe pain was almost unchanged, whereas it increased among cancer patients, reaching a significantly higher rate than among noncancer patients in 2021 (31.9% vs 27.4%, P < .01).

CONCLUSIONS

Our findings suggest potential unintended consequences for cancer care because of efforts to manage opioid-related risks.

Machine learning-based evaluation of spontaneous pain and analgesics from cellular calcium signals in the mouse primary somatosensory cortex using explainable features

Introduction

Pain that arises spontaneously is considered more clinically relevant than pain evoked by external stimuli. However, measuring spontaneous pain in animal models in preclinical studies is challenging due to methodological limitations. To address this issue, recently we developed a deep learning (DL) model to assess spontaneous pain using cellular calcium signals of the primary somatosensory cortex (S1) in awake head-fixed mice. However, DL operate like a "black box", where their decision-making process is not transparent and is difficult to understand, which is especially evident when our DL model classifies different states of pain based on cellular calcium signals. In this study, we introduce a novel machine learning (ML) model that utilizes features that were manually extracted from S1 calcium signals, including the dynamic changes in calcium levels and the cell-to-cell activity correlations.

Method

We focused on observing neural activity patterns in the primary somatosensory cortex (S1) of mice using two-photon calcium imaging after injecting a calcium indicator (GCaMP6s) into the S1 cortex neurons. We extracted features related to the ratio of up and down-regulated cells in calcium activity and the correlation level of activity between cells as input data for the ML model. The ML model was validated using a Leave-One-Subject-Out Cross-Validation approach to distinguish between non-pain, pain, and drug-induced analgesic states.

Results and discussion

The ML model was designed to classify data into three distinct categories: non-pain, pain, and drug-induced analgesic states. Its versatility was demonstrated by successfully classifying different states across various pain models, including inflammatory and neuropathic pain, as well as confirming its utility in identifying the analgesic effects of drugs like ketoprofen, morphine, and the efficacy of magnolin, a candidate analgesic compound. In conclusion, our ML model surpasses the limitations of previous DL approaches by leveraging manually extracted features. This not only clarifies the decision-making process of the ML model but also yields insights into neuronal activity patterns associated with pain, facilitating preclinical studies of analgesics with higher potential for clinical translation.

Evaluating the Aspects of Quality of Life in Individuals with Substance Use Disorder: A Systematic Review Based on the WHOQOL Questionnaire

Substance Use Disorder (SUD) has become a significant public health concern and it profoundly impacts an individual's quality of life (QOL). This systematic review aimed to assess the QOL among patients with SUD, and to understand the differential impact of SUD on physical, mental, social, and environmental QOL domains, considering a variety of substances and identifying key factors that influence these outcomes. A comprehensive search was conducted in PubMed, Web of Science, Cochrane, and Scopus in January 2023, covering literature published until December 2022. The QOL was assessed using the World Health Organization Quality of Life (WHOQOL) instrument and the brief version of the WHOQOL, identifying the same four domains of QOL (physical, mental, social, and environmental). A total of 19 studies were selected for inclusion in the systematic review, based on individuals' polysubstance use, and excluding those using only nicotine or alcohol. The analysis included 6079 patients, with only 40.3% women, and a mean age of 36.6 years. The substances most commonly involved in SUD were cocaine (47.1%), alcohol (46.3%), and amphetamine (43.6%), considering most individuals being polysubstance users. The highest variability in QOL scores was observed in the physical domain. Mental disorders were reported in 68.3% of the patients, while long-term use of drugs, criminal history, unemployment, and low levels of education were identified as significant predictors for lower QOL by some of the studies. Similarly, sleep problems and teeth decay were also identified as significant worsening factors for QOL. This systematic review highlights that the WHOQOL survey is widely accepted and applicable for individuals with SUD worldwide. The results suggest a substantial negative impact of SUD on the QOL of affected individuals. The findings underscore the need for comprehensive interventions to address the physical, psychological, social, and environmental dimensions of QOL among individuals with SUD.

Analysis of Pain Management after Anatomic VATS Resection in Austrian Thoracic Surgery Units

BACKGROUND

Postoperative pain influences rehabilitation, postoperative complications and quality of life. Despite its impact, there are no uniform treatment guidelines. Different centers seem to use various strategies. This study aims to analyze pain management regimens used after anatomic VATS resections in Austrian thoracic surgery units, with a special interest in opioid usage and strategies to avoid opioids.

METHODS

A questionnaire was designed to assess the use of regional anesthesia, postoperative pain medication and characteristics of individual pain management regimens. The questionnaire was sent to all thoracic surgery units in Austria, with nine out of twelve departments returning them.

RESULTS

All departments use regional anesthesia during the procedure. Four out of nine centers use epidural analgesia or an intercostal catheter for postoperative regional anesthesia in at least 50% of patients. Two departments follow an opioid restrictive regimen, five depend on the visual analogue scale (VAS) and two administer opioids on a fixed schedule. Three out of nine departments use NSAIDs on a fixed schedule. The most used medication is metamizole (eight out of nine centers; six on a fixed schedule, two depending on VAS) followed by piritramide (six out of nine centers; none as a fixed prescription).

CONCLUSIONS

This study reflects the heterogeneity in postoperative pain treatment after VATS anatomic lung resections. All departments use some form of regional anesthesia in the perioperative period; prolonged regional anesthesia is not utilized uniformly to reduce opioid consumption, as suggested in enhanced recovery after surgery programs. More evidence is needed to optimize and standardize postoperative pain treatment.

Trauma Exposure Across the Lifespan among Individuals Engaged in Treatment with Medication for Opioid Use Disorder: Differences by Gender, PTSD Status, and Chronic Pain

Conclusions

The study found a high prevalence of lifetime trauma among people in MOUD. Results highlight the need for comprehensive assessment and mental health services to address trauma among those in MOUD treatment.

Piloting an opioid callback program in community pharmacies

BACKGROUND

Although opioid prescribing has recently trended downward, opioid-related overdoses and deaths have drastically increased. Community pharmacists are accessible health care providers who are well positioned to disseminate information on opioid safety and to educate and counsel on medication use, managing adverse events, and proper medication disposal. Patient callbacks facilitate appropriate medication usage. We developed an opioid callback program that provides a framework for pharmacists to follow up with patients with an opioid prescription.

OBJECTIVES

This study aimed to (1) describe the development of the opioid callback initiative and (2) report results from a pilot test in 2 community pharmacies.

METHODS

The opioid callback process and data collection forms were collaboratively developed with community pharmacists at each site. Data recorded on the opioid callback forms were descriptively analyzed and chi-square test of independence explored differences by pain durations related to opioid disposal, security, and safety. Participating pharmacy staff were interviewed to identify facilitators and barriers to implementation, as well as opportunities for improvement.

RESULTS

Forty-one opioid callbacks were attempted and 36 were completed (87.8%). Pharmacists were statistically significantly more likely to discuss naloxone with patients with chronic pain (89.5%) than those with acute pain (46.2%). Pharmacists reported that the program successfully raised awareness of opioid disposal opportunities and safe opioid practices, including storage and naloxone ownership. They expressed patients' willingness to answer questions and appreciation for the extra attention and care.

CONCLUSION

Community pharmacists are well positioned to address the opioid crisis as access points for medication questions, opioid safety education, opioid disposal, naloxone, and medications for people with an opioid use disorder. This study presents a proof of concept for a pharmacist-led opioid callback program. Expansion could help inform patients about how to use opioids safely, how to treat an opioid overdose, and where to dispose of unused medications.

What can we learn from COVID-19 to improve opioid treatment? Expert providers respond

BACKGROUND

The COVID-19 pandemic has had devasting effects on drug abuse treatment systems already stressed by the opioid crisis. Providers within opioid use disorder (OUD) outpatient treatment programs have had to adjust to rapid change and respond to new service delivery provisions such as telehealth and take-home medication. Using the COVID-19 pandemic and subsequent organizational challenges as a backdrop, this study explores providers' perspectives about strategies and policies that, if made permanent, can potentially improve access to and quality of OUD treatment.

METHODS

This qualitative study was conducted in Los Angeles County, which has one of the largest substance use disorder (SUD) treatment systems in the United States serving a diverse population, including communities impacted by the opioid crisis. We collected qualitative interview data from 30 high-performing programs (one manager/supervisor per program) where we based high performance on empirical measures of access, retention, and program completion outcomes. The study team completed data collection and analysis using constructivist grounded theory (CGT) to describe the social processes in which the participating managers engaged when faced with the pandemic and subsequent organizational changes. We developed 14 major codes and six minor codes with definitions. The interrater reliability tests showed pooled Cohen's kappa statistic of 93 %.

RESULTS

Our results document the impacts of COVID-19 on SUD treatment systems, their programmatic responses, and the strategic innovations they developed to improve service delivery and quality and which managers plan to sustain within their organizations.

CONCLUSION

Providers identified three primary areas for strategic innovation designed to improve access and quality: (1) designing better medication utilization, (2) increasing telemedicine capacity, and (3) improving reimbursement policies. These strategies for system transformation enable us to use lessons from the COVID-19 pandemic to direct policy and programmatic reform, such as expanding eligibility for take-home medication and enhancing access to telehealth services.

Identification of opioid use disorder using electronic health records: Beyond diagnostic codes

BACKGROUND

We used structured and unstructured electronic health record (EHR) data to develop and validate an approach to identify moderate/severe opioid use disorder (OUD) that includes individuals without prescription opioid use or chronic pain, an underrepresented population.

METHODS

Using electronic diagnosis grouper text from EHRs of ~1 million patients (2012-2020), we created indicators of OUD-with "tiers" indicating OUD likelihood-combined with OUD medication (MOUD) orders. We developed six sub-algorithms with varying criteria (multiple vs single MOUD orders, multiple vs single tier 1 indicators, tier 2 indicators, tier 3 and 4 indicators). Positive predictive values (PPVs) were calculated based on chart review to determine OUD status and severity. We compared demographic and clinical characteristics of cases identified by the sub-algorithms.

RESULTS

In total, 14,852 patients met criteria for one of the sub-algorithms. Five sub-algorithms had PPVs ≥0.90 for any severity OUD; four had PPVs ≥0.90 for moderate/severe OUD. Demographic and clinical characteristics differed substantially between groups. Of identified OUD cases, 31.3% had no past opioid analgesic orders, 79.7% lacked evidence of chronic prescription opioid use, and 43.5% lacked a chronic pain diagnosis.

DISCUSSION

Incorporating unstructured data with MOUD orders yielded an approach that adequately identified moderate/severe OUD, identified unique demographic and clinical sub-groups, and included individuals without prescription opioid use or chronic pain, whose OUD may stem from illicit opioids. Findings show that incorporating unstructured data strengthens EHR algorithms for identifying OUD and suggests approaches limited to populations with prescription opioid use or chronic pain exclude many individuals with OUD.

Use of Big Data and Ethical Issues for Populations With Substance Use Disorder

With expanding data availability and computing power, health research is increasingly relying on big data from a variety of sources. We describe a state-level effort to address aspects of the opioid epidemic through public health research, which has resulted in an expansive data resource combining dozens of administrative data sources in Massachusetts. The Massachusetts Public Health Data Warehouse is a public health innovation that serves as an example of how to address the complexities of balancing data privacy and access to data for public health and health services research. We discuss issues of data protection and data access, and provide recommendations for ethical data governance. Keeping these issues in mind, the use of this data resource has the potential to allow for transformative research on critical public health issues.

Festivals following the easing of COVID-19 restrictions: Prevalence of new psychoactive substances and illicit drugs

The market for illicit drugs and new psychoactive substances (NPS) has grown significantly and people attending festivals have been identified as being at high risk (high extent and frequency of substance use). Traditional public health surveillance data sources have limitations (high costs, long implementation times, and ethical issues) and wastewater-based epidemiology (WBE) can cost-effectively support surveillance efforts. Influent wastewater samples were analyzed for NPS and illicit drug consumption collected during New Year period (from 29-Dec-2021 to 4-Jan-2022) and a summer Festival (from 29-June-2022 to 12-July-2022) in a large city in Spain. Samples were analyzed for phenethylamines, cathinones, opioids, benzodiazepines, plant-based NPS, dissociatives, and the illicit drugs methamphetamine, MDA, MDMA, ketamine, heroin, cocaine, and pseudoephedrine by liquid chromatography mass spectrometry. High consumption rates of specific NPS and established illicit drugs were identified at the peak of each event. Furthermore, a dynamic change in NPS use (presence and absence of substances) was detected over a period of six months. Eleven NPS, including synthetic cathinones, benzodiazepines, plant-based NPS and dissociatives, and seven illicit drugs were found across both the New Year and summer Festival. Statistically significant differences (p < 0.05) were seen for 3-MMC (New Year vs summer Festival), eutylone (New Year vs summer Festival), cocaine (summer Festival vs normal week and summer Festival vs New Year), MDMA (New Year vs normal week and summer Festival vs normal week), heroin (summer Festival vs New Year) and pseudoephedrine (summer Festival vs New Year). This WBE study assessed the prevalence of NPS and illicit drugs at festivals following the reduction of the COVID-19 pandemic restrictions highlighting the high use of specific substances at the peak of each event. This approach identified in a cost-effective and timely manner without any ethical issues the most used drugs and changes in use patterns and, thus, can complement public health information.

Exploring Gender and Ethnoracial Differences and Trends in Methamphetamine Treatment

Introduction

Given the significant rise in methamphetamine use and related mortality in the United States, it is critical to explore differences in treatment trends with particular attention to women and ethnoracial groups in hard-hit areas like Los Angeles County.

Methods

We analyzed a large sample across 4 waves: 2011 (105 programs, 10 895 clients), 2013 (104 programs, 17 865 clients), 2015 (96 programs, 16 584 clients), and 2017 (82 programs, 15 388 clients). We completed a comparative analysis to identify differences across subgroups and a trend analysis of treatment episodes by gender and ethnoracial group to differentiate users of methamphetamine and users of other drugs.

Results

Treatment clients using methamphetamine increased over time for each gender and race. There were also significant differences across age groups. Women comprised a greater proportion of treatment episodes involving methamphetamine use (43.3%) compared to all other drugs combined (33.6%). Latinas represented 45.5% of methadone-related admissions. Compared with other drug users, methamphetamine users had a lower successful treatment completion rate and were served by programs with less financial and culturally responsive capacity.

Conclusions

Findings highlight a sharp increase in treatment admissions for methamphetamine users of all gender and ethnocultural groups. Women, especially Latinas, saw the most significant increases, with a widening gender gap over time. All subgroups of methamphetamine users had a lower treatment completion rate compared with users of other drugs, and critical differences existed in the programs where they received services.

Alleviation of Pain, PAIN Interference, and Oxidative Stress by a Novel Combination of Hemp Oil, Calamari Oil, and Broccoli: A Randomized, Double-Blind, Placebo-Controlled Trial

Chronic pain is a critical health issue in the US that is routinely managed pharmacologically with diminishing results. The widespread misuse and abuse of prescription opioid pain medications have caused both healthcare providers and patients to seek alternative therapeutic options. Several dietary ingredients have been traditionally used for pain relief and are known to have potential analgesic properties. This double-blind, placebo-controlled randomized clinical trial aimed to test whether a novel combination of full spectrum hemp oil (phytocannabinoids), calamari oil (omega-3 fatty acids), and broccoli (glucosinolates) could reduce chronic pain and attenuate damage from oxidative stress in adults seeking chiropractic care. Participants (average age = 54.8 ± 13.6 years old) were randomly assigned to consume a whole-food, multi-ingredient supplement (n = 12, intervention and standard chiropractic care) or placebo (n = 13, mineral oil and standard chiropractic care) daily for 12 weeks. The subjects' self-reported perceived pain, pain interference, and reactive oxygen species (ROS) status in the peripheral blood mononuclear cells (PBMC) were quantified at baseline, mid-checkpoint, and postintervention. The intervention was positively associated with a 52% decrease in pain intensity and several parameters of pain interference, including quality of sleep. Decreases in the markers of oxidative stress were also observed in the participants from the intervention group (29.4% decrease in PMBC ROS). Our findings indicated that supplementation with a novel combination of hemp oil, calamari oil, and broccoli has the potential to manage chronic pain when combined with standard chiropractic care, as suggested by its effects on pain intensity and oxidative stress.

Estimated Reductions in Opioid Overdose Deaths With Sustainment of Public Health Interventions in 4 US States

Importance

In 2021, more than 80 000 US residents died from an opioid overdose. Public health intervention initiatives, such as the Helping to End Addiction Long-term (HEALing) Communities Study (HCS), are being launched with the goal of reducing opioid-related overdose deaths (OODs).

Objective

To estimate the change in the projected number of OODs under different scenarios of the duration of sustainment of interventions, compared with the status quo.

Design, Setting, and Participants

This decision analytical model simulated the opioid epidemic in the 4 states participating in the HCS (ie, Kentucky, Massachusetts, New York, and Ohio) from 2020 to 2026. Participants were a simulated population transitioning from opioid misuse to opioid use disorder (OUD), overdose, treatment, and relapse. The model was calibrated using 2015 to 2020 data from the National Survey on Drug Use and Health, the US Centers for Disease Control and Prevention, and other sources for each state. The model accounts for reduced initiation of medications for OUD (MOUDs) and increased OODs during the COVID-19 pandemic.

Exposure

Increasing MOUD initiation by 2- or 5-fold, improving MOUD retention to the rates achieved in clinical trial settings, increasing naloxone distribution efforts, and furthering safe opioid prescribing. An initial 2-year duration of interventions was simulated, with potential sustainment for up to 3 additional years.

Main Outcomes and Measures

Projected reduction in number of OODs under different combinations and durations of sustainment of interventions.

Results

Compared with the status quo, the estimated annual reduction in OODs at the end of the second year of interventions was 13% to 17% in Kentucky, 17% to 27% in Massachusetts, 15% to 22% in New York, and 15% to 22% in Ohio. Sustaining all interventions for an additional 3 years was estimated to reduce the annual number of OODs at the end of the fifth year by 18% to 27% in Kentucky, 28% to 46% in Massachusetts, 22% to 34% in New York, and 25% to 41% in Ohio. The longer the interventions were sustained, the better the outcomes; however, these positive gains would be washed out if interventions were not sustained.

Conclusions and Relevance

In this decision analytical model study of the opioid epidemic in 4 US states, sustained implementation of interventions, including increased delivery of MOUDs and naloxone supply, was found to be needed to reduce OODs and prevent deaths from increasing again.

Exploring Chronic Pain and Pain Management Perspectives: Qualitative Pilot Analysis of Web-Based Health Community Posts

BACKGROUND

Patient perspectives are central to the US Food and Drug Administration's benefit-risk decision-making process in the evaluation of medical products. Traditional channels of communication may not be feasible for all patients and consumers. Social media websites have increasingly been recognized by researchers as a means to gain insights into patients' views about treatment and diagnostic options, the health care system, and their experiences living with their conditions. Consideration of multiple patient perspective data sources offers the Food and Drug Administration the opportunity to capture diverse patient voices and experiences with chronic pain.

OBJECTIVE

This pilot study explores posts from a web-based patient platform to gain insights into the key challenges and barriers to treatment faced by patients with chronic pain and their caregivers.

METHODS

This research compiles and analyzes unstructured patient data to draw out the key themes. To extract relevant posts for this study, predefined keywords were identified. Harvested posts were published between January 1, 2017, and October 22, 2019, and had to include #ChronicPain and at least one other relevant disease tag, a relevant chronic pain management tag, or a chronic pain management tag for a treatment or activity specific to chronic pain.

RESULTS

The most common topics discussed among persons living with chronic pain were related to disease burden, the need for support, advocacy, and proper diagnosis. Patients' discussions focused on the negative impact chronic pain had on their emotions, playing sports, or exercising, work and school, sleep, social life, and other activities of daily life. The 2 most frequently discussed treatments were opioids or narcotics and devices such as transcutaneous electrical nerve stimulation machines and spinal cord stimulators.

CONCLUSIONS

Social listening data may provide valuable insights into patients' and caregivers' perspectives, preferences, and unmet needs, especially when conditions may be highly stigmatized.

Identifying gender differences in risk profiles and in opioid treatment outcomes in Los Angeles County

Policies and programs that aim to minimize wait time to enter opioid use disorder (OUD) treatment and maximize retention respond to potential differences in female and male clients' risk profiles. We conducted multigroup latent class analysis using significant individual risk factors. Our sample included 13,453 opioid treatment episodes from 135 unique substance use disorder treatment programs in Los Angeles County, California, in four waves: 2011 (66 programs, 1035 clients), 2013 (77 programs, 3671 clients), 2015 (75 programs, 4625 clients), and 2017 (69 programs, 4106 clients). Groups at risk of waiting longer included clients who were female, had mental health issues, received medication for OUD, had criminal justice involvement, received mandated referrals, had children in child protective services, and had caretaker responsibilities. All clients with children in protective services were likely to wait longer than those not in protective services, but women waited longer. Findings highlight that: (a) women and men in OUD treatment have significant health and social problems; (b) female and male clients have distinct risk profiles; and (c) targeted services responding to risk profiles may improve treatment access and engagement. Findings have implications for health policy and program evaluation and planning in the delivery of treatment services considering gendered risk factors.

Environmental enrichment facilitates electric barrier induced heroin abstinence after incubation of craving in male and female rats

BACKGROUND

Treatment strategies that aim to promote abstinence to heroin use and reduce vulnerability to drug-use resumption are limited in sustainability and long-term efficacy. We have previously shown that environmental enrichment (EE), when implemented after drug self-administration, reduces drug-seeking and promotes abstinence to cocaine and heroin in male rats. Here, we tested the effects of EE on abstinence in an animal conflict model in males and females, and after periods where incubation of craving may occur.

METHODS

Male and female rats were trained to self-administer heroin followed by 3 or 21 days of a no-event-interval (NEI). Following NEI, rats were permanently moved to environmental enrichment (EE) or new standard (nEE) housing 3 days prior to resuming self-administration in the presence of an electric barrier adjacent to the drug access lever. Electric barrier current was increased daily until rats ceased self-administration.

RESULTS

We found that 21 days of NEI led to significantly greater heroin self-administration and a trend toward shorter latencies to emit the first active lever press in the first abstinence session compared to 3 days of NEI. EE, when compared to nEE, led to longer latencies in the first abstinence session. Also, EE groups of both sexes and in both NEIs achieved abstinence criteria in significantly fewer numbers of sessions.

CONCLUSIONS

EE facilitates abstinence in males and females and after periods where incubation of craving may occur. This suggests that EE may benefit individuals attempting to abstain from heroin use and may aid in the development of long term treatment strategies.

Commentary on Adams et al.: using administrative big data for the public good

Adams et al demonstrate why US states should learn from Massachusetts on how to build “administrative big data” warehouses for the public good. However, these and other existing data resources must include detailed information on criminal-legal-carceral experiences. Offering buprenorphine treatment in syringe service programs would remove healthcare obstacles and save lives.

Discovery of pyrazole-1-carboxamide derivatives as novel Gi-biased μ-opioid receptor agonists

μ-Opioid receptor (MOR) Gi-biased agonists with no recruitment of β-arrestin were introduced as a new analgesic strategy to overcome the conventional undesirable side effects of opioid receptor-targeted drugs, such as tolerance, addiction, respiratory depression, and constipation. For the development of novel Gi-biased MOR agonists, the design, synthesis, and structure-activity relationship (SAR) analysis of the aminopyrazole core skeleton were conducted according to the current SAR data of PZM21 (2a) and its derivatives. New derivatives were biologically evaluated for their agonistic effects on cyclic adenosine monophosphate (cAMP) levels for the Gi pathway and β-arrestin recruitment in MOR/κ-opioid receptor/δ opioid receptor. An optimized selective Gi-biased agonist, Compound 17a, was discovered with potent cAMP inhibitory activities, with a 50% efficacy concentration value of 87.1 nM and no activity in the MOR β-arrestin pathway and other subtypes. The in vivo pain relief efficacy of Compound 17a was confirmed in a dose-dependent manner with spinal nerve ligation and cisplatin-induced peripheral neuropathy rodent neuropathic pain models.

The Grieving Process of Opioid Overdose Bereaved Parents in Maryland

In recent years, the opioid epidemic in the United States has garnered attention due to the increasing number of fatal overdoses. Research on overdose death has increasingly focused on the psychological impacts of drug-related bereavement and disenfranchised bereavement. This study aims to contribute to the growing body of emergent literature on drug death bereavement, by exploring the experiences of parents whose children passed away due to opioid overdose. Qualitative semi-structured interviews were conducted with six parents living in the state of Maryland who had an adult child die from opioid overdose two or more years prior to the study. Data was analyzed using thematic analysis. Themes that emerged included the grieving process, stigmatization, and social support. While overall adaptation levels varied among participants, all participants reported positive and negative outcomes related to their experience of grief and loss. Implications for clinical practice and intervention are discussed.

Integrating Social Determinants of Health With Tobacco Treatment for Individuals With Opioid Use Disorder: Feasibility and Acceptability Study of Delivery Through Text Messaging

Background

Individuals with opioid use disorder (OUD) have a high prevalence of smoking and frequently experience unmet social determinants of health (SDOH), which may be barriers to smoking cessation. Hospitalization is an opportunity to encourage smoking cessation. Unfortunately, many clinicians do not provide tobacco treatment to support the maintenance of cessation achieved during hospitalization. Interventions are required to support these high-risk individuals after hospital discharge.

Objective

This study aimed to test the feasibility and acceptability of a 28-day SMS text messaging program tailored to individuals with OUD, which provides smoking cessation support and addresses unmet SDOH needs.

Methods

From July to December 2019, we enrolled 25 individuals who were hospitalized with tobacco dependence and OUD at our large safety net hospital. The SMS text messaging program was initiated during hospitalization and continued for 28 days. Participants were enrolled in either the ready to quit within 30 days or the not ready to quit within 30 days program based on their readiness to quit. Automated SMS text messages were sent twice daily for 4 weeks. The topics included health and cost benefits of quitting, both general and opioid specific (16 messages); managing mood and stress (8 messages); motivation, coping strategies, and encouragement (18 messages); addressing medication misconceptions (5 messages); links to resources to address substance use (2 messages providing links to the Massachusetts Substance Use Helpline and Boston Medical Center resources), tobacco dependence (1 message providing a link to the Massachusetts Quitline), and unmet SDOH needs (6 messages assessing SDOH needs with links to resources if unmet SDOH needs were identified). Questionnaires and interviews were conducted at baseline and at 2 and 4 weeks after enrollment.

Results

The participants were 56% (14/25) female, 36% (9/25) African American, 92% (23/25) unemployed, and 96% (24/25) Medicaid insured. Approximately 84% (21/25) activated the program, and none of the participants unsubscribed. Approximately 57% (12/21) completed either the 2- or 4-week questionnaires. Program satisfaction was high (overall mean 6.7, SD 0.8, range 1-7). Many perceived that the SMS text messaging program provided social support, companionship, and motivation to stop smoking. Messages about the health benefits of quitting were well received, whereas messages on how quitting cigarettes may prevent relapse from other substances had mixed views, highlighting the importance of tailoring interventions to patient preferences.

Conclusions

SMS text messaging to promote smoking cessation and address SDOH needs may be an effective tool for improving quit rates and health outcomes in individuals with tobacco dependence and OUD. Our study adds to the growing body of evidence that SMS text messaging approaches are feasible and acceptable for providing tobacco treatment to all individuals who smoke, even among low-income populations who have OUD and are not ready to quit.

A pilot study of a mixed-method approach to design an ED-based peer mHealth referral tool for HIV/HCV and opioid overdose prevention services

BACKGROUND

The intersecting epidemics of opioid misuse, injection drug use, and HIV/HCV have resulted in record overdose deaths and sustained high levels of HIV/HCV transmissions. Literature on social networks suggests opportunities to connect people who use drugs (PWUD) and their peers to HIV/HCV and opioid overdose prevention services. However, little evidence exists on how to design such peer referral interventions in emergency department (ED) settings.

METHODS

A mixed-method study was conducted to assess the feasibility of an mHealth-facilitated 'patient to peer social network referral program' for PWUD. In-depth interviews (IDIs) and quantitative surveys were conducted with urban ED patients (n = 15), along with 3 focus group discussions (FGDs) (n = 19).

RESULTS

Overall, 34 participants were enrolled (71 % males, 53 % Black). 13/15 IDI participants reported a history of opioid overdose; all had witnessed overdose events; all received HIV/HCV testing. From survey responses, most would invite their peers for HIV/HCV testing and naloxone training; and anticipated peers to accept referrals (HIV: 60 %, HCV: 73 %, naloxone: 93 %). Qualitative data showed PWUD shared health-related information with each other but preferred word of mouth rather than text messages. Participants used smartphones regularly and suggested using Internet advertising for prevention services. Participants expressed enthusiasm for ED-based peer mHealth referral platform to prevention services, as well as referring their peers to proposed services, with monetary incentives.

CONCLUSION

ED-based peer referral intervention to HIV/HCV testing and naloxone training was viewed favorably by PWUD. Frequent smartphone use among PWUD suggests that the medium could be a promising mode for peer referral.

Need for and Receipt of Substance Use Disorder Treatment Among Adults, by Gender, in the United States

OBJECTIVES

Disparities in substance use disorder (SUD) treatment use persist across groups, including gender. Using a gender-informed approach to expand treatment capacity and reduce barriers to treatment engagement is vital. We examined SUD treatment need and receipt among people with SUD in the United States, by gender, and assessed gender-specific sociodemographic factors associated with unmet need for SUD treatment and reported treatment barriers.

METHODS

We conducted an analysis of data among adults aged ≥18 with a past-year SUD from the National Survey on Drug Use and Health (2015-2018). We computed population-adjusted frequencies and proportions for SUD treatment need and receipt and assessed gender differences. Multivariate logistic regression assessed gender-specific sociodemographic variables associated with SUD treatment receipt.

RESULTS

Among adults with a past-year SUD, 63.4% were men and 36.6% were women (P < .001), only 10.6% received SUD treatment, and a greater percentage of women than men needed treatment for opioid use disorder (11.9% vs 9.9%; P = .002). Receipt of SUD treatment was lowest among women with alcohol use disorder followed by men with alcohol use disorder (7.5% vs 8.9%; P = .052). Non-Latinx Black men had fewer than half the adjusted odds of receiving SUD treatment than non-Latinx White men (adjusted odds ratio [aOR] = 0.44; 95% CI, 0.27-0.71). Latinx women (aOR = 0.37; 95% CI, 0.18-0.73) and non-Latinx Black women (aOR = 0.51; 95% CI, 0.27-0.94) had significantly lower odds of receiving SUD treatment than non-Latinx White women.

CONCLUSIONS

As public health efforts target expanding SUD treatment capacity and addressing disparities in use of SUD treatment, interventions informed by gender and culture should be prioritized.

“We need to build a better bridge”: findings from a multi-site qualitative analysis of opportunities for improving opioid treatment services for youth

Background

Adolescence and young adulthood is an important period for substance use initiation and related harms. In the context of the ongoing opioid crisis, the risks for youth (ages 16–29) who use opioids are particularly heightened. Despite recommendations to adopt a developmentally appropriate and comprehensive approach to reduce opioid-related harms among youth, data continue to show that youth are not adequately engaged in opioid treatments and encounter many barriers. The aim of this study is to identify youth-centered opportunities for improving opioid treatment services.

Methods

This paper reports multi-site qualitative findings from youth participating in the ‘Improving Treatment Together’ project, a community-based participatory project being conducted in British Columbia and Alberta, two western Canadian provinces that have been dramatically impacted by the opioid crisis. Qualitative data were collected during three workshops with youth who used opioids and accessed opioid treatment services in the prior 12 months. These workshops were conducted in three communities following the core elements of human-centered co-design. A multi-site qualitative analysis was conducted to identify within- and between-site themes surrounding youths’ needs for improving opioid treatment service experiences and outcomes.

Results

Three overarching needs themes were identified from across the communities. The first reflected youths’ difficulties finding and staying connected to opioid treatment services, with the overarching need theme suggesting opportunities to reduce organizational and systems-related barriers to care, such as waiting times and wider information about service availability. The second area of need was rooted in youths’ feelings of judgment when accessing services. Consequently, opportunities to increase respectful and empathic interactions were the overarching need. The final theme was more nuanced across communities and reflected opportunities for an individualized approach to opioid treatment services that consider youths’ unique basic safety, social, and health needs.

Conclusions

This study identifies fundamental directions for the operationalization and implementation of youth-centered opioid treatment services. These directions are contextualized in youths’ lived experiences accessing services in their local communities, with overarching themes from across sites strengthening their transferability to other settings.

The Prevalence and Negative Impacts of Substance Use Disorders among People with HIV in the United States: A Real-Time Delphi Survey of Key Stakeholders

Although HIV and substance use disorders (SUDs) constitute a health syndemic, no research to date has examined the perceived negative impacts of different SUDs for people with HIV (PWH). In May 2019, 643 stakeholders in the U.S., representing clients of AIDS service organizations (ASOs), ASO staff, and HIV/AIDS Planning Council members, participated in an innovative Stakeholder-Engaged Real-Time Delphi (SE-RTD) survey focused on the prevalence and individual-level negative impact of five SUDs for PWH. The SE-RTD method has advantages over conventional survey methods by efficiently sharing information, thereby reducing the likelihood that between-group differences are simply due to lack of information, knowledge, and/or understanding. The population-level negative impacts were calculated by weighting each SUD's individual-level negative impact on indicators of the HIV Care Continuum and other important areas of life by the perceived prevalence of each SUD. Overall, we found these SUDs to have the greatest population-level negative impact scores (possible range 0-24): alcohol use disorder (population-level negative impact = 6.9; perceived prevalence = 41.9%), methamphetamine use disorder (population-level negative impact = 6.5; perceived prevalence = 3.2%), and opioid use disorder (population-level negative impact = 6.4; perceived prevalence = 34.6%). Beyond further demonstration of the need to better integrate SUD services within HIV settings, our findings may help inform how finite funding is allocated for addressing the HIV-SUD syndemic within the U.S. Based on our findings, such future efforts should prioritize the integration of evidence-based treatments that help address use disorders for alcohol, methamphetamine, and opioids.

Strengthening Communities: A Qualitative Assessment of Opportunities for the Prevention of Adverse Childhood Experiences in the Wake of the Opioid Crisis

The opioid crisis is a significant challenge for health and human service systems that serve children, youth, and families across the United States. Between 2000 and 2017, the number of foster care entries, a type of adverse childhood experience (ACE), attributable to parental drug use increased by 147%. Nevertheless, there is variation in the burden of opioid overdose and foster care rates across the U.S., suggesting community supports and systems to support families affected by substance use also vary. This qualitative study sampled communities experiencing high and low rates of overdose mortality and foster care entries (i.e., a qualitative comparison group) to better understand what might protect some counties from high overdose mortality and foster care entries. The sample included six counties from three states that were selected based on their rates of opioid overdose mortality and foster care entries. Using purposive sampling within counties, interview and discussion group participants included multi-sector community partners, parents whose children had been removed due to parental substance use, and caregivers caring for children who had been removed from their homes. Across all counties, prevention was not front-of-mind. Yet, participants from communities experiencing high rates of overdose mortality and foster care entries identified several factors that might help lessen exposure to substance use and ACEs including more community-based prevention services for children and youth. Both parents and caregivers across all communities also described the need for additional supports and services. Participants also described the impact of COVID-19 on services, including greater utilization of mental health and substance use treatment services and the challenges with engaging children and youth on virtual platforms. The implications for prevention are discussed, including the need to encourage primary prevention programs in communities.

A Comparison of Sex-Specific Reproductive and Sexual Health Needs between Addiction Medicine and Primary Care Treatment Settings

Introduction: Reproductive and sexual health (RSH) is an important component of wellness and recovery for people with substance use disorder (SUD). Evidence to guide better integration of RSH services into SUD treatment is limited. Our objectives were to compare 1) unmet RSH needs; and 2) barriers to RSH service utilization between care settings providing treatment for SUD or other chronic medical conditions. Methods: Participants at two outpatient clinics, addiction medicine (women n = 91, men n = 75) and primary care (women n = 59, men n = 50), completed a one-time electronic survey between July and September 2019. Separately for men and women, comparisons between addiction medicine and primary care groups were made using Pearson χ², Fisher's Exact, and T-tests. Results: Participants were 75.0% Black and aged 49.4 years. Overall, unmet RSH needs were less prevalent among participants at the primary care than the addiction medicine clinic, such as receipt of a past 12-month sexual exam (men: 36.0% vs. 17.3%; women: 55.6% vs. 30.1%). The most common barrier to RSH service receipt was cost (men: 59.4%; women: 52.6%), followed by fear of judgment for drug/alcohol use for SUD participants (men: 33% vs. 12%; women: 26% vs. 7%). Many SUD participants expressed high desire for integrated RSH services into the addiction medicine clinic (men: 51.4%; women: 59.8%). Conclusion/Implications: The integration of RSH into addiction medicine is lagging compared to care settings for people with other chronic medical conditions. Future research should focus on advancing sex- and gender-informed RSH service integration into SUD treatment settings.

Data needs and models for the opioid epidemic

The evolving nature of the opioid epidemic and continued increases in overdose deaths highlight a need for fundamental change in the collection and use of surveillance data to link them to implementation of effective service, treatment, and prevention approaches. Yet at present, the quality and timeliness of US surveillance data often limits data-driven approaches. We review current information needs, summarize limitations of existing data, propose complementary surveillance resources, and provide examples of promising approaches designed to meet the needs of data end-users. We conclude that there is a need for an approach that focuses on the needs of data end-users, such as public health systems leaders, policy makers, public, nonprofit and prepaid healthcare systems, and other systems, such as the justice system. Such an approach, which may require investments in new infrastructure, should prioritize improvements in data timeliness, sample representativeness, database linkage, and increased flexibility to adapt to shifts in the environment, while preserving the privacy of survey participants. Use of simulations, distributed research and data networks, alternative data sources, such as wastewater or digital data collection and use of blockchain technology, are some of promising avenues toward an improved and more user-centered surveillance system.

Perception of Resource Allocations to Address the Opioid Epidemic

OBJECTIVES

Despite billions of dollars spent on opioid policy initiatives, public knowledge of evidence-based policies to reduce opioid-related morbidity remain low. Consequences of this knowledge gap for support of initiatives remains understudied. Our objective was to evaluate how participants with and without lived experience allocate funding for initiatives to address the opioid epidemic. A secondary objective was to collect proof-of-concept data of an informational intervention designed to improve support for evidence-based policies.

METHODS

Participants (N = 284; 57.2% female) without lifetime nonmedical opioid use (n = 98) and those with lifetime use (past year [n = 81] or nonpast year [n = 105]) of nonmedical opioids were recruited. All participants reported how they would allocate funds to demand reduction, supply reduction, harm reduction, and treatment policies. Half of all participants were then randomized to a brief informational intervention designed to emphasize evidence-based harm reduction and treatment programs.

RESULTS

Funding allocations were highest for policies related to community services and treatment and lowest for those related to harm reduction. Participants with lived experience allocated less to supply reduction policies. Participants (12%) who reallocated funds after information exposure increased funding to supervised consumption sites, dz = 0.77, naloxone distribution, dz = 0.85, syringe exchange programs, dz = 0.63, and medications for opioid use disorder access, dz = 0.70.

CONCLUSIONS

This study illustrates how people with and without lived experience prioritize various policies to address the opioid epidemic and emphasize comparably low support for harm reduction policies. Proof-of-concept data suggest that brief informational interventions may increase funding support for harm reduction strategies, at least in a subset of people.

Interpersonal Trauma Among Women and Men Receiving Buprenorphine in Outpatient Treatment for Opioid Use Disorder

People with opioid use disorder (OUD) are vulnerable to negative health outcomes related to substance use and psychosocial issues, such as interpersonal trauma (IPT). Participants receiving buprenorphine completed a cross-sectional survey (July-September 2019). OUD outcomes were prospectively abstracted over a 28-week timeframe. More than a third reported recent IPT (40% women, 36% men). Sexual violence was more common among women than men (p = .02). For women only, IPT was associated with substance use during follow-up (β = 20.72, 95% CI: 4.24, 37.21). It is important for public health strategies in the opioid crisis to address IPT using sex- and gender-informed approaches.

Do people with opioid use disorder and posttraumatic stress disorder benefit from dding Individual opioid Drug Counseling to buprenorphine?

BACKGROUND AND PURPOSE

Large randomized trials have found that behavioral therapy for opioid use disorder (e.g., Individual Drug Counseling, Cognitive Behavioral Therapy for Opioid Use Disorder) does not improve buprenorphine maintenance outcomes, on average, for individuals with opioid use disorder. However, recent studies indicate that certain subgroups of patients may benefit from the addition of behavioral therapy to buprenorphine. In particular, people with more complex and severe psychosocial needs may benefit from the addition of behavioral therapy for opioid use disorder.

METHODS

In this study, we conducted a secondary analysis of a large, multi-site randomized trial (N = 357) of buprenorphine maintenance with and without individual Opioid Drug Counseling (ODC) for the treatment of opioid use disorder. We hypothesized that participants with posttraumatic stress disorder (PTSD) would benefit from the addition of ODC.

RESULTS

Logistic regression models indicated a significant PTSD by treatment condition interaction. Specifically, 67% of those with PTSD had a successful opioid use disorder treatment outcome when they were assigned to receive both ODC and buprenorphine, compared to a 36% response rate among those who received buprenorphine alone.

CONCLUSIONS

Although these results require replication, our findings provide initial indication that ODC is an important complement to buprenorphine maintenance treatment for people with co-occurring PTSD and opioid use disorder.

Trends in heroin use and injection drug use among high school students in five urban school districts in the US (2005-2017)

Background. We describe the prevalence of and changes in heroin use and injection drug use (IDU) among high school students in five large, urban school districts in the US (2005-2017); nearly three-fourths of the students were Black and/or Hispanic/Latino.Methods. Data are from the Centers for Disease Control and Prevention's "Youth Risk Behavior Survey" program, which includes biennial surveys in urban school districts. We pooled data across districts and survey years, and then generated weighted prevalence estimates (and 95% CIs) for any lifetime heroin use and IDU. Joinpoint regression modeling was used to estimate changes in prevalence over the study period.Results. Biennial prevalence estimates (2005-2017) for heroin use and IDU were above 1.8% for all seven timepoints. In 2017, prevalence of heroin use and IDU were 2.9% and 2.5%, respectively. Both heroin use and IDU were higher among boys than girls. There were statistically significant increases in heroin use and IDU among girls from 2005-2009, whereas changes over time were stable among boys.Conclusions. High school students in large, urban school districts may have higher rates of heroin use and IDU than US high school students in general, and there is little evidence of increases since 2009. This study suggests that adolescence may be a critical period for initiation of heroin use among adolescents in large urban school districts, the majority of whom are Black and/or Latino.Supplemental data for this article is available online at https://doi.org/10.1080/15332640.2021.1992327 .

Improving Treatment Together: a protocol for a multi-phase, community-based participatory, and co-design project to improve youth opioid treatment service experiences in British Columbia

Background

Opioid use is one of the most critical public health issues as highly potent opioids contribute to rising rates of accidental opioid-related toxicity deaths. This crisis has affected people from all age groups, including youth (ages 15–24) who are in a critical developmental period where the stakes of opioid use are especially high. Efforts to reduce the significant harms of opioid use have focused on the expansion of evidence-based treatments, including medications for opioid use disorder (e.g. buprenorphine). While these treatments are unequivocally life saving, recent evidence suggests that they may not align with youths’ needs. Accordingly, the ‘Improving Treatment Together’ (ITT) project has been designed with the aim to improve youths’ opioid treatment service experiences and outcomes by co-developing, implementing, and measuring youth-centred opioid use treatment service innovations. This manuscript describes the protocol for this multi-phase project.

Methods

The ITT project follows community-based participatory research (CBPR) and strategically integrates co-design processes throughout its four phases. Upon establishing a project partnership between national, provincial and community-based organizations, Phase 1 follows four core elements of human-centred co-design (empathy, needs identification, ideation, prototyping) in nine separate workshops. These workshops will be held in four diverse communities with youth, caregivers and service providers who have accessed or delivered opioid treatment services. Phase 1 will culminate in the co-production of opioid treatment service innovations to be considered by the project’s partners for further co-development, pilot testing, and wider implementation during the remaining phases of the project. Throughout each phase, the project will collect and analyse both qualitative and quantitative research and evaluation data to determine the project’s impact.

Discussion

This protocol provides a detailed description of the ITT project, with an emphasis on the project’s application of co-design and CBPR processes, the planned research and implementation procedures, and the establishment of a unique partnership. To our knowledge, this is one of the first projects to integrate these participatory processes to the design, implementation and measurement of youth-centred opioid treatment services. Embedding these processes throughout each phase of the project will strengthen the relevance and feasibility of the project’s service delivery innovations.

A Demographic and Regional Comparison of Opioid-Related Hospital Visits within Community Type in the United States

BACKGROUND

The opioid epidemic is a complex national crisis in the United States with a 400% increase in related deaths over the past two decades with no signs of slowing. The purpose of this study was to assess the incidence of opioid use, based on the geographic and population characteristics.

METHODS

The opioid-related hospital inpatient stays and emergency department visits obtained from the 2010 to 2018 Healthcare Cost and Utilization Project and demographic confounders, including age, race, education, and income gathered from US Census data were analyzed through generalized linear mixed models and reported by community size and region.

RESULTS

Opioid use varies among population center sizes and the region analyzed. In general, opioid visits in the southwest region were greatest across the majority of population center sizes. Rural usage was greatest in the northeast, southeast, and southwest. Unemployment and diverse ethnicities were commonly associated with opioid use in the metro areas studied but these associations were not seen in rural areas.

CONCLUSION

Opioid use remains significant among diverse populations across the United States. Understanding the unique dynamics associated with opioid usage in populations within the regions studied is important in guiding future interventions to fight this crisis.

Influence of G protein-biased agonists of μ-opioid receptor on addiction-related behaviors

Opioid analgesics remain a gold standard for the treatment of moderate to severe pain. However, their clinical utility is seriously limited by a range of adverse effects. Among them, their high-addictive potential appears as very important, especially in the context of the opioid epidemic. Therefore, the development of safer opioid analgesics with low abuse potential appears as a challenging problem for opioid research. Among the last few decades, different approaches to the discovery of novel opioid drugs have been assessed. One of the most promising is the development of G protein-biased opioid agonists, which can activate only selected intracellular signaling pathways. To date, discoveries of several biased agonists acting via μ-opioid receptor were reported. According to the experimental data, such ligands may be devoid of at least some of the opioid side effects, such as respiratory depression or constipation. Nevertheless, most data regarding the addictive properties of biased μ-opioid receptor agonists are inconsistent. A global problem connected with opioid abuse also requires the search for effective pharmacotherapy for opioid addiction, which is another potential application of biased compounds. This review discusses the state-of-the-art on addictive properties of G protein-biased μ-opioid receptor agonists as well as we analyze whether these compounds can diminish any symptoms of opioid addiction. Finally, we provide a critical view on recent data connected with biased signaling and its implications to in vivo manifestations of addiction.

Research on substance use disorders during the COVID-19 pandemic

The COVID-19 pandemic has triggered changes in the substance use disorder (SUD) treatment delivery system, in the availability of legal and illicit drugs, and in other social and economic factors. As such, these changes necessitate that the field re-evaluate research approaches to SUDs, including in epidemiology, clinical trials, health services, implementation and policy research, as well as basic and translational neuroscience. COVID-19 has reduced researchers' access to target populations and made it difficult for them to obtain timely data to monitor changes in patterns of drug use and overdoses. These changes have increased researchers' interest in virtual technologies to expand and accelerate access to populations; increased modifications in the design, conduct, and analysis of clinical trials; and increased emphasis on implementation. Similarly, as researchers better understand the biology of COVID-19, they will better understand potential effects of COVID-19 on neurotransmitter receptors and signaling pathways, mechanisms underlying COVID-19 associated neurological and psychiatric sequelae, and interactions between COVID-19 treatments and psychoactive substances. The pandemic has also revealed the need for research that addresses health disparities. Overall, the COVID-19 pandemic has challenged several aspects of current research on SUD. Responding to these challenges provides opportunities to develop robust research approaches that align with the goals of improving patient outcomes and public health and are resilient to the challenges of future crises.

Examining the Relationship between Social Connection and Opioid Misuse: A Systematic Review

METHODS

We used a Boolean search strategy of PubMed, PsycINFO, and Embase to identify eligible publications from January 1990 to March 2020 and narrative analysis to synthesize the evidence.

RESULTS

The database search identified 1267 independent citations; 29 publications met inclusion criteria. Nearly all the studies demonstrated high risk of bias, most often due to selection and confounding bias. Most of the studies in the review (k = 20, 69%) found at least one significant association between social connection and opioid outcomes. Although no two studies included the same measures of social connection or opioid misuse, and social connection was both positively and negatively associated with opioid misuse, results support that social connection is an important correlate of opioid misuse.

CONCLUSIONS

This review highlights the importance of social connection as a correlate to opioid misuse. However, the extensive variability among research studies points to a need for standardization of measurement and larger studies with diverse populations to allow for consequential recommendations for prevention or treatment of opioid misuse. Evidence regarding the associations between social connection and opioid misuse or disorder is sparse. We provide suggestions for advancing this research, including clarification of the complex influences between social connections and opioid misuse.

Improving retention across the OUD service cascade upon reentry from jail using Recovery Management Checkups-Adaptive (RMC-A) experiment

Incarcerated individuals with opioid use disorders (OUD) should be linked to community-based treatment with medications for opioid use disorder (MOUD) upon their release, as well as to services that provide support for their ongoing recovery. The RMC-A experiment will test an adapted version of the evidence-based Recovery Management Checkups (RMC), which provides treatment linkage, support for retention, and re-linkage as indicated at quarterly checkups. A total of 750 male and female individuals will be recruited from 5 county jails in Illinois and randomly assigned to 1 of 3 groups at release from jail: a) Monitoring and Treatment Referral (MTR); b) quarterly RMC (RMC-Q); or c) RMC-A, which adjusts the frequency and intensity of checkups based on the individual's assessed need for treatment at each checkup. Measurement includes quarterly research follow-up assessments for 2 years, urine tests, and records checks (treatment, mortality, recidivism). The study aims to evaluate: (1) the direct effects of RMC-Q/RMC-A on MOUD treatment initiation, engagement, retention, and re-linkage; (2) the indirect effects of RMC-Q/RMC-A (via months of MOUD) on public health outcomes (days of opioid use, OUD symptoms, quality of life, cost of health care utilization); (3) the indirect effects of RMC-Q/RMC-A (via months of MOUD and public health outcomes) on public safety outcomes (illegal activity, re-arrest, re-incarceration, cost of crime); and (4) the incremental costs and cost-effectiveness of MTR vs. RMC-Q vs. RMC-A on public health and public safety outcomes. This experiment will determine whether the adapted RMC model improves the overall effectiveness and cost-effectiveness of the fixed quarterly RMC.

Developing a community-supported risk reduction intervention for syringe exchange registrants and their drug-free family or friends: a pilot study

BACKGROUND

People engaged in injection opioid use often have drug-free family or friends that could be mobilized to support risk reduction and treatment seeking.

OBJECTIVE

This pilot study evaluated the feasibility and preliminary efficacy of a 6-week community-supported risk reduction group intervention for syringe exchange program (SEP) registrants and drug-free network members.

METHOD

The group provided risk reduction and treatment readiness education, with weekly assignments for participants to engage together in community activities designed to meet other drug-free people.

RESULTS

Thirty-nine SEP registrants (and 39 community supports) enrolled in the study, and 21 pairs attended at least one group. For this smaller sample, participants attended 67% of scheduled sessions and engaged in scheduled activities during 42% of the study weeks, with 48% of SEP participants (n = 10) choosing to enter substance use disorder treatment. SEP participants who entered treatment reported reduced rates of injection drug use, opioid use, and cocaine use.

CONCLUSIONS

While this intervention shows promise for linking syringe exchange and substance use disorder treatment participation in select SEP registrants, outcomes demonstrating low demand and modest acceptability suggest that additional research is necessary to understand barriers to participation and motivate higher levels of engagement.

Lack of rewarding effects of a soluble epoxide hydrolase inhibitor TPPU in mice: Comparison with morphine

AIM

Although opioids have been used as treatment of neuropathic pain, opioids have abuse potential in humans. Since soluble epoxide hydrolase (sEH) in the metabolism of polyunsaturated fatty acids plays a key role in the pain, sEH inhibitors would be promising new therapeutic drugs for neuropathic pain. In this study, we examined the effect of the sEH inhibitor TPPU on rewarding effects in mice using the conditioned place preference (CPP) paradigm.

METHODS

The rewarding effects of morphine (10 mg/kg) and TPPU (3, 10, or 30 mg/kg) in mice were examined using CPP paradigm. Furthermore, the effect of TPPU (30 mg/kg) on morphine-induced rewarding effects was examined.

RESULTS

TPPU (3, 10, or 30 mg/kg) did not increase CPP scores in the mice whereas morphine significantly increased CPP scores in the mice. Furthermore, pretreatment with TPPU did not block the rewarding effects of morphine in the mice, suggesting that sEH does not play a role in the rewarding effect of morphine.

CONCLUSION

This study suggests that TPPU did not have rewarding effects in rodents. This would make sEH inhibitors potential therapeutic drugs without abuse potential for neuropathic pain.
