RESUMO

This supplemental issue describes the individual studies and collaborative efforts of the Helping to End Addiction Long-term Prevention Cooperative's (HPC's) innovative approaches to rapidly develop evidence-based prevention programs for widespread dissemination. This introduction succinctly reviews (1) the context that demands the rapid development of efficacious prevention programs and their scale-ups, (2) the unique objectives of the individual HPC research projects, and (3) collective efforts to harmonize research across studies to advance the prevention of opioid misuse and gain insight into opioid misuse etiology to inform improvements in preventive interventions. At the conclusion of HPC studies, we anticipate the availability of multiple evidence-based programs to prevent opioid misuse and use disorder for persons who experience particular sources of risk and for delivery in settings where prevention has traditionally been lacking. By harmonizing and coordinating efforts across 10 distinct outcomes studies of prevention programs and making data available for analysis by non-HPC researchers, the HPC's efficacy and etiology evidence will far surpass the additive contributions of 10 individual research projects.

RESUMO

BACKGROUND: Recent policies have lessened restrictions around prescribing buprenorphine-naloxone (buprenorphine) for the treatment of opioid use disorder (OUD). The primary concern expressed by critics of these policies is the potential for buprenorphine diversion. However, the population-level effects of increased buprenorphine diversion are unclear. If replacing the use of heroin or fentanyl, use of diverted buprenorphine could be protective. METHODS: Our study aim was to estimate the impact of buprenorphine diversion on opioid overdose using an agent-based model calibrated to North Carolina. We simulated the progression of opioid misuse and opioid-related outcomes over a 5-year period. Our status quo scenario assumed that 50% of those prescribed buprenorphine diverted at least one dose per week to other individuals with OUD and 10% of individuals with OUD used diverted buprenorphine at least once per week. A controlled prescription only scenario assumed that no buprenorphine would be diverted, while an increased diversion scenario assumed that 95% of those prescribed buprenorphine diverted and 50% of individuals with OUD used diverted buprenorphine. We assumed that use of diverted buprenorphine replaced the use of other opioids for that day. Sensitivity analyses increased the risk of overdose when using diverted buprenorphine, increased the frequency of diverted buprenorphine use, and simulated use of diverted buprenorphine by opioid-naïve individuals. Scenarios were compared on opioid overdose-related outcomes over the 5-year period. RESULTS: Our status quo scenario predicted 10,658 (credible interval [CI]: 9699-11,679) fatal opioid overdoses. A scenario simulating controlled prescription only of buprenorphine (i.e., no diversion) resulted in 10,741 (9895-11,650) fatal opioid overdoses versus 10,301 (9439-11,244) within a scenario simulating increased diversion. Compared to the status quo, the controlled prescription only scenario resulted in a similar number of fatal overdoses, while the scenario with increased diversion of buprenorphine resulted in 357 (3.35%) fewer fatal overdoses. Even when increasing overdose risk while using diverted buprenorphine and incorporating use by opioid naïve individuals, increased diversion did not increase overdoses compared to a scenario with no buprenorphine diversion. CONCLUSIONS: A similar number of opioid overdoses occurred under modeling conditions with increased rates of buprenorphine diversion among persons with OUD, with non-statistical trends toward lower opioid overdoses. These results support existing calls for low- to no-barrier access to buprenorphine for persons with OUD.

RESUMO

BACKGROUND: Unprecedented increases in substance-related overdose fatalities have been observed in Texas and the U.S. since the onset of the COVID-19 pandemic and have made clear there is considerable need to reduce harms associated with drug use. At the federal level, initiatives have called for widespread dissemination and implementation of evidence-based harm reduction practices to reduce overdose deaths. Implementation of harm reduction strategies is challenging in Texas. There is a paucity of literature on understanding current harm reduction practices in Texas. As such, this qualitative study aims to understand harm reduction practices among people who use drugs (PWUD), harm reductionists, and emergency responders across four counties in Texas. This work would inform future efforts to scale and spread harm reduction in Texas. METHODS: Semi-structured qualitative interviews were conducted with N = 69 key stakeholders (25 harm reductionists; 24 PWUD; 20 emergency responders). Interviews were transcribed verbatim, coded for emergent themes, and analyzed using Applied Thematic Analysis with Nvivo 12. A community advisory board defined the research questions, reviewed the emergent themes, and assisted with interpretation of the data. RESULTS: Emergent themes highlighted barriers to harm reduction at micro and macro levels, from the individual experience of PWUD and harm reductionists to systemic issues in healthcare and the emergency medical response system. Specifically, (1) Texas has existing strengths in overdose prevention and response efforts on which to build, (2) PWUD are fearful of interacting with healthcare and 911 systems, (3) harm reductionists are in increasing need of support for reaching all PWUD communities, and (4) state-level policies may hinder widespread implementation and adoption of evidence-based harm reduction practices. CONCLUSIONS: Perspectives from harm reduction stakeholders highlighted existing strengths, avenues for improvement, and specific barriers that currently exist to harm reduction practices in Texas.

RESUMO

Background: Drug overdose deaths in Texas have been accelerating in recent years with an increase of 33% in the 12 months leading up to December 2020. Accurate counts of nonfatal overdoses - including associated aspects of overdose, such as substances involved, demographic information, and reversal agents administered is critical to increase timely and adequate response to individuals and communities in need. Methods: Twenty semi-structured interviews were conducted with harm reduction workers across four Texas counties to understand existing methods of reporting overdoses, naloxone dissemination/administration, and recommendations for improving overdose surveillance. Interviews were transcribed and emergent themes were identified based on the a priori research goals. Results: Findings highlighted a variety of overdose data collection methods and tools among harm reduction organizations including Excel spreadsheet, web-based TONI application, notes on personal cell phones, and paper notes. Types of overdose data collected varied widely. Participants noted existing methods are suboptimal and that there is a need for a unified, statewide reporting system to improve overdose data capture. Participants also highlighted that overdose surveillance should include "hidden populations" of people who use drugs that are not currently counted in surveillance methods as a result of not interacting with the healthcare system. Conclusions: Texas lacks a unified overdose reporting system to capture critical data to inform overdose response and prevention efforts. Nontraditional reporters may be critical toward improving overdose syndromic efforts and capturing data among hard-to-reach populations. Harm reduction organizations are uniquely positioned to facilitate reporting among community gatekeepers and people who use drugs.

RESUMO

BACKGROUND: The prevalence of deaths involving synthetic opioids has historically been lower in Texas than most U.S. states but more than quadrupled from January 2020 to January 2022. This paper explores the emergence of fentanyl in a drug supply where black tar heroin predominates, a factor considered protective against fentanyl adulteration, through the perspectives of people who use drugs (PWUD). OBJECTIVES: We describe experiences of unintentional exposure to fentanyl, illustrate how some people identify fentanyl in their supply, and present harm reduction strategies that PWUD use to avoid overdose. METHODS: Thirty rapid assessment interviews were conducted in July 2021 at 2 mobile outreach sites of a harm reduction organization in Austin, Texas. The brief semistructured interviews were designed to assess participant fentanyl exposure experiences. RESULTS: Participants were clients who reported using heroin or fentanyl in the past week and had lived in Texas for at least 6 months. Seventeen participants identified as male, 10 as female, and 3 as nonbinary. Half identified as white; other participants were Latinx (6), black (2), American Indian (1), and mixed race (6). Two-thirds were unhoused or in transitional housing. The drug supply in Texas has evolved; most participants reported that the heroin and other drugs they obtained contain fentanyl. Participants detected differences by observing changes in the physical characteristics of the drug, experiencing unexpected effects, and using fentanyl test strips. Many had been unintentionally exposed to fentanyl and expressed concerns about fentanyl's presence. The presence of fentanyl had negative unintended consequences for participants, including adverse effects and developing a dependence on opioids. CONCLUSION: PWUD in Austin, Texas, report increasing prevalence of unintentional fentanyl exposure, despite the predominance of black tar heroin. Pharmacists can provide crucial supplies and education to safeguard the health of this vulnerable population.

RESUMO

OBJECTIVE: To determine whether any combinations of state-level public health activities were necessary or sufficient to reduce prescription opioid dispensing. DESIGN: We examined 2016-2019 annual progress reports, 2014-2019 national opioid dispensing data (IQVIA), and interview data from states to categorize activities. We used crisp-set Qualitative Comparative Analysis to determine which program activities, individually or in combination, were necessary or sufficient for a better than average decrease in morphine milligram equivalent (MME) per capita. SETTING: Twenty-nine US state health departments. PARTICIPANTS: State health departments implementing the Centers for Disease Control and Prevention's Prevention for States (PfS) program. MAIN OUTCOME: Combinations of prevention activities related to changes in the rate of prescription opioid MME per capita dispensing from 2014 to 2019. RESULTS: Three combinations were sufficient for greater than average state-level reductions in MME per capita: (1) expanding and improving proactive reporting in combination with enhancing the uptake of evidence-based opioid prescribing guidelines and not moving toward a real-time Prescription Drug Monitoring Program; (2) implementing or improving prescribing interventions for insurers, health systems, or pharmacy benefit managers in combination with enhancing the uptake of evidence-based opioid prescribing guidelines; and (3) not implementing or improving prescribing interventions for insurers, health systems, or pharmacy benefit managers in combination with not enhancing the uptake of evidence-based opioid prescribing guidelines. Interview data suggested that the 3 combinations indicate how state contexts and history with addressing opioid overdose shaped programming and the ability to reduce MME per capita. CONCLUSIONS: States successful in reducing opioid dispensing selected activities that built upon existing policies and interventions, which may indicate thoughtful use of resources. To maximize impact in addressing the opioid overdose epidemic, states and agencies may benefit from building on existing policies and interventions.

RESUMO

Power analysis informs a priori planning of behavioral and medical research, including for randomized clinical trials that are nomothetic (i.e., studies designed to infer results to the general population based on interindividual variabilities). Far fewer investigations and resources are available for power analysis of clinical trials that follow an idiographic approach, which emphasizes intraindividual variabilities between baseline (control) phase versus one or more treatment phases. We tested the impact on statistical power to detect treatment outcomes of four idiographic trial design factors that are under researchers' control, assuming a multiple baseline design: sample size, number of observations per participant, proportion of observations in the baseline phase, and competing statistical models (i.e., hierarchical modeling versus piecewise regression). We also tested the impact of four factors that are largely outside of researchers' control: population size, proportion of intraindividual variability due to residual error, treatment effect size, and form of outcomes during the treatment phase (phase jump versus gradual change). Monte Carlo simulations using all combinations of the factors were sampled with replacement from finite populations of 200, 1750, and 3500 participants. Analyses characterized the unique relative impact of each factor individually and all two-factor combinations, holding all others constant. Each factor impacted power, with the greatest impact being from larger treatment effect sizes, followed respectively by more observations per participant, larger samples, less residual variance, and the unexpected improvement in power associated with assigning closer to 50% of observations to the baseline phase. This study's techniques and R package better enable a priori rigorous design of idiographic clinical trials for rare diseases, precision medicine, and other small-sample studies.

RESUMO

OBJECTIVE: Academic detailing is a clinical education technique characterized by targeted, one-on-one, interactive conversations between trained staff and the clinician. This study describes variations in implementing academic detailing among jurisdictions receiving funding from the U.S. Centers for Disease Control and Prevention (CDC) to prevent prescription drug overdoses. DESIGN: In 2015, CDC started the Prescription Drug Overdose Prevention for States (PfS) program. SUBJECTS: This study focuses on 11 of the 29 funded jurisdictions that implemented academic detailing as part of their PfS efforts. METHODS: Jurisdictions provided annual progress reports from 2016 to 2019. We conducted semistructured interviews in 2017 and 2018 with all funded jurisdictions and conducted follow-up interviews with three jurisdictions in 2020 to obtain additional context. We used an analytic matrix display to identify themes from annual progress report data, the coding report from the 2017/2018 interviews, and the three follow-up interviews from 2020. RESULTS: Two academic detailing models emerged: 1) one-on-one detailing, where centrally trained staff conducted all visits, and 2) a train-the-trainer model. Jurisdictions also described a hybrid model, which they referred to as academic detailing despite not meeting the definition of academic detailing. We identified variations in delivery strategies, staffing, and curriculum development within and between models. Despite these differences, common themes included the need to use data to focus academic detailing and the importance of partnerships. CONCLUSIONS: Adoption of academic detailing as a strategy for improving opioid prescribing behaviors has increased. However, there is limited guidance and standardization to guide and evaluate implementation and outcomes.

RESUMO

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.

RESUMO

The Substance Abuse and Mental Health Services Administration's Strategic Prevention Framework Partnerships for Success (PFS) program supports community-based organizations (CBOs) across the United States in implementing evidence-based prevention interventions to reduce substance use in adolescents and young adults. Little attention has been paid to how CBOs combine interventions to create comprehensive community-specific prevention approaches, or whether different approaches achieve similar community-level effects on prescription drug misuse (PDM). We used PFS evaluation data to address these gaps. Over 200 CBOs reported their prevention intervention characteristics, including strategy type (e.g., prevention education, environmental strategies) and number of unique interventions. Evaluation staff coded whether each intervention was an evidence-based program, practice, or policy (EBPPP). Latent Class Analysis of seven characteristics (use of each of five strategy types, use of one or more EBPPP, and number of interventions implemented) identified six prevention approach profiles: High Implementation EBPPP, Media Campaigns, Environmental EBPPP, High Implementation Non-EBPPP, Prevention Education, and Other Information Dissemination. All approaches except Media Campaigns and Other Information Dissemination were associated with significant reductions in community-level PDM. These approaches may need to be paired with other, more direct, prevention activities to effectively reduce PDM at the community level. However, similar rates of change in PDM across all 6 prevention approaches suggests only weak evidence favoring use of the other four approaches. Community-based evaluations that account for variability in implemented prevention approaches may provide a more nuanced understanding of community-level effects. Additional work is needed to help CBOs identify the most appropriate approach to use based on their target communities' characteristics and resources.

RESUMO

OBJECTIVE: Text-messaging interventions positively affect health behaviors, but their use on college campuses has been limited. Text messaging serves as a relatively affordable way to communicate with large audiences and is one of the preferred modes of communication for young adults. This study examined the feasibility and acceptability of a campus-wide, health text-messaging program. PARTICIPANTS: The subscriber pool consisted of approximately 6,000 undergraduate students from a large, southern university. From that pool, 1,095 participants (64% female; 41% White) completed a posttest survey. METHOD: Text messages covered a range of health topics and information about campus resources. Research was conducted from August through December 2015. Process data were collected throughout the semester; participants' attitudes were assessed via an online survey at the program's conclusion. RESULTS: Students demonstrated engagement with the messages throughout the semester as evidenced by replies to text-back keywords and clicks on website links embedded within messages. Messages about sleep, stress management, and hydration were considered most relevant. The majority of participants (61%) reported increased awareness regarding their health. CONCLUSIONS: Text-messaging interventions are a feasible strategy to improve college student health.

RESUMO

BACKGROUND: The concurrent use of alcohol and tobacco has a multiplicative effect on both social and physical consequences. While it is known that alcohol and tobacco use are strongly correlated in emerging adulthood, there is significant individual variability in use. However, little research has examined how patterns of concurrent use are related over time. OBJECTIVES: The current study explores these longitudinal conjoint trajectories, as well as the associated sociodemographic factors. METHODS: We used sequential latent class growth analysis to explore the co-occurring longitudinal patterns of recent alcohol and tobacco use across emerging adulthood (10 data collection periods, 2004-2009) with a diverse sample of 2,244 college students (60% female; 54% White). RESULTS: Twenty distinct patterns of conjoint alcohol and tobacco use were found. There was more variation in tobacco use trajectories among alcohol users than variation in alcohol trajectories among tobacco users. Using multinomial logistic regression models we determined the impact of sociodemographic characteristics on classification into each conjoint pattern versus the normative trajectory (Abstaining tobacco/Low alcohol). Male gender, White race, fraternity/sorority affiliation, and higher family income were significantly associated with riskier conjoint trajectory patterns. Conclusions/Importance: Findings highlight the diversity of alcohol and tobacco use behaviors across emerging adulthood. The low variation in alcohol use among tobacco users indicates that tobacco use is a significant risk factor for heavier drinking. A better understanding of the covarying use of these two ubiquitous substances may provide new avenues for preventing and reducing the use of both.

RESUMO

INTRODUCTION: Almost one-third of college students report recent cigarette use, primarily as "social smoking," and often in conjunction with alcohol use. While city-wide indoor smoking bans effectively reduce the number of social opportunities to smoke (eg, bars and music clubs), little is known about how these bans may impact the smoking behaviors of college students. Furthermore, nothing is known about how indoor smoking bans may impact students' drinking behaviors. The current study aims to determine the impact of a city-wide comprehensive indoor smoking ban on smoking and alcohol behaviors among a longitudinal sample of emerging adults. METHODS: Data are from a 6-year longitudinal study (10 waves of data collection) that began the summer before college enrollment. Participants (N = 2244; 60% female) reported on their past 3-month smoking and drinking behaviors using Internet-based surveys at each wave. Piecewise linear growth modeling was used to determine how a city-wide comprehensive indoor smoking ban (implemented in the Fall of 2005 between Waves 4 and 5) impacted smoking frequency, cigarette quantity, drinking frequency, and number of binge drinking episodes. RESULTS: Smoking and alcohol use increased from the summer before college through the semester before implementation of the city-wide smoking ban. While smoking frequency (P < .001) and cigarette quantity (P < .05) declined after the ban, drinking frequency increased (P < .001) and the number of binge drinking episodes remained stable. CONCLUSIONS: Current findings suggest that comprehensive indoor smoking bans can influence the smoking behaviors of emerging adults, whereas trajectories of drinking are relatively unchanged.

RESUMO

Girls with early pubertal timing are at elevated risk for teenage childbearing; however, the modifiable mechanisms driving this relationship are not well understood. The objective of the current study was to determine whether substance use, perceived peer substance use, and older first sexual partners mediate the relationships among girls' pubertal timing, sexual debut, and teenage childbearing. Data are from Waves 1-15 of the female cohort of the National Longitudinal Surveys of Youth 1997 (NLSY97), a nationwide, ongoing cohort study of U.S. men and women born between 1980 and 1984. The analytic sample (n = 2066) was 12-14 years old in 1997 and ethnically diverse (51 % white, 27 % black, 22 % Latina). Using structural equation modeling, we found substance use in early adolescence and perceived peer substance use each partially mediated the relationships among girls' pubertal timing, sexual debut, and teenage childbearing. Our findings suggest early substance use behavior as one modifiable mechanism to be targeted by interventions aimed at preventing teenage childbearing among early developing girls.

RESUMO

Self-report measures of perceived pubertal timing correspond only weakly with clinical measures of "objective" physical development. Peer and school contexts shape adolescents' self-perceptions of pubertal timing. The current study examined associations between perceived pubertal timing and the pubertal timing reported by nominated friends and schoolmates. Participants included 2817 adolescents (Mage = 16.6; 49 % female; 16 % Black; 20 % Hispanic) from the National Longitudinal Study of Adolescent Health. Three measures of pubertal timing were included: age-standardized ratings of body changes, comparisons of development relative to peers (relative timing), and, in females, age at menarche. It was hypothesized that relative timing, which explicitly asks adolescents to compare themselves to their peers, would be related to the age-standardized pubertal timing of nominated friends and schoolmates. Surprisingly, there were no associations between relative timing and age-standardized pubertal timing reported by peers, suggesting that pubertal self-perceptions do not fluctuate in response to the average level of development in a friend group. Instead, males were similar to nominated friends and schoolmates in age-standardized ratings of body changes, and females were similar to nominated friends in relative timing, controlling for race, ethnicity, and age. Different self-report measures of pubertal timing index different underlying constructs, and the social processes that influence adolescents' perceptions of pubertal maturation may differ between genders.

RESUMO

The present study tests whether aggression and prosocial behavior can coexist as part of a socially functional and adaptive profile among early adolescents. Using a person-centered approach, the study examined early adolescents' likelihood of being classified into profiles involving aggressive and prosocial behavior, social status (popular, liked, cool), machiavellianism, and both affective and cognitive components of empathy (empathic concern and perspective taking, respectively). Participants were 1170 early adolescents (10-12 years of age; 52% male) from four schools in metropolitan Santiago, Chile. Through latent profile analysis, three profiles emerged (normative-low aggressive, high prosocial-low aggressive, and high aggressive-high popular status). Both empathic concern and perspective taking were higher in the high prosocial-low aggressive profile, whereas the high aggressive-high popular status profile had the lowest scores on both empathy components as well as machiavellianism. No profile emerged where aggressive and prosocial behaviors were found to co-exist, or to be significantly above the mean. The results underscore that aggressive behavior is highly contextual and likely culturally specific, and that the study of behavioral profiles should consider social status as well as socio-emotional adjustment indicators. These complex associations should be taken into consideration when planning prevention and intervention efforts to reduce aggression or school bullying and to promote positive peer relationships.

RESUMO

BACKGROUND: Experiencing drug cravings is an aspect of substance use disorders that frequently compromises the recovery efforts of people who use drugs. Most treatment approaches that address drug cravings either involve cognitive strategies or medication. Few interventions directly address the physiological aspects of craving, such as increased heart rate. Previous research has demonstrated that slow-paced breathing may be effective in managing drug cravings by manipulating an individual's heart rate. The purpose of this paper is to describe a study protocol for an intervention that offers resonance frequency breathing training for managing cravings via a smartphone application (app). METHODS: This trial is registered in ClinicalTrials.gov (Identifier: NCT05830773). The intervention focuses on persons in recovery from opioid use disorder who receive services from the Texas Health and Human Service Commission Recovery Support Services division. Participants will be trained to use Camera Heart Rate Variability (CHRV), a resonance frequency breathing app. The CHRV app measures heart rate and the volumetric variations of blood circulation. When experiencing stress, anxiety, or cravings, participants will use the app to practice breathing exercises. Participants (N = 60) will also complete surveys at baseline, 4 weeks, and 8 weeks; the survey questions, covers demographic characteristics, personal trauma history, substance use experience, and utilization of substance use treatment services. The surveys will also include psychosocial measures of craving, stress, and anxiety to allow the study team to assess changes between baseline and study completion. Participants who complete the full 8-week intervention will be invited to participate in a 30-minute interview about their experience with the app. Interviews will provide details on implementation outcomes, including acceptability, appropriateness, and feasibility. CONCLUSION: Many evidence-based interventions for opioid use require interpersonal communication with individuals in one's recovery network. However, individuals may be unable to engage others in their recovery network in the moments when they are experiencing cravings or stress- and anxiety-related triggers. Therefore, recovery support interventions that emphasize individual self-management of cravings, stress, and anxiety when they occur can empower individuals in recovery and enhance existing interventions.

RESUMO

System-involved youth are a vulnerable population at high-risk of experiencing numerous sexual reproductive health (SRH) outcomes. They are likely to have several risk factors for teen pregnancy and parenting including abuse and neglect histories, lack of a supportive consistent adult in their lives, and limited opportunities to experience normal romantic relationships. Issues of pubertal development are rarely addressed in this population. Data is from system-involved adolescents (n = 301) enrolled in a SRH intervention. The final analysis is restricted to those who were sexually active at baseline (n = 229). Most participants were African Americans between 13-21 years of age. More than 70% reported an early mean age of first sex. Approximately a quarter self-reported early pubertal development. Logistic regression was utilized to examine the odds of pregnancy in relation to self-reported pubertal timing. The findings support the need to develop programming for system-involved youth which address their unique needs.
