Do drug treatment facilities increase clients' exposure to potential neighborhood-level triggers for relapse? A small-area assessment of a large, public treatment system

"Expected to happen": perspectives on post-release overdose from recently incarcerated people with opioid use disorder

BACKGROUND

Opioid-related overdose is the leading cause of death for people recently released from incarceration, however treatment with medications for opioid use disorder (MOUD) during incarceration can reduce the mortality risk. This study seeks to qualitatively analyze perceptions of post-release overdose risk from the perspectives of people who received MOUD while incarcerated in one of eight Massachusetts jails during 2021-2022 using the Risk Environment Framework to guide analyses.

METHODS

N = 38 participants with lived experience of MOUD treatment during incarceration who are now living in the community were interviewed on factors that may contribute to or protect against post-release overdose risk. Themes were identified inductively and deductively using the Risk Environment Framework and its domains, which organizes themes along physical, social, economic, and policy environments on both the micro- and macro- scales.

RESULTS

The physical risk environment included loss of opioid tolerance during incarceration, polysubstance use, and the toxicity of the regional drug supply as key producers of increased risk for post-release overdose. Social drivers of risk included peer group risk norms-including peer-driven harm reduction practices and interpersonal relationships between drug sellers and buyers-as well as macro-level social determinants of health such as housing insecurity and availability of mental health services. Economic drivers of post-release overdose risk included lack of income generation during incarceration and employment challenges. Participants discussed several aspects of policy that contribute to post-release overdose risk, including availability of harm reduction supplies, public health services, and broader policy around MOUD.

CONCLUSIONS

The perspectives of people with lived experience are vital to understanding the disproportionate risks of overdose for those recently released from incarceration. Our results highlight the intersectional factors that produce and reproduce the post-release overdose risk environment, providing support for interventions across each domain of the Risk Environment Framework. By capturing perspectives from people with lived experience of OUD and incarceration during this critical period of risk, we can better identify interventions that target and mitigate overdose-related harm in this population.

Spatial and Environmental Correlates of Prevalence of Treatment for Substance Use Disorders, Retention, and SUD Services Utilization in South Sardinia

This study explored the economic, social, and spatial correlates of treatment prevalence, retention, and service utilization for substance use disorder (SUD) in South Sardinia. Data from 1,667 patients with an ICD-10 diagnosis of SUD were extracted from the medical records of individuals assisted by three public addiction services in 2019. We used a spatial autoregressive model, a parametric proportional hazard model, and Poisson regression to examine the associations of spatial factors and residents' socioeconomic status with the prevalence of treatment at the census block level, treatment retention, and SUD service utilization at the individual level. The prevalence was higher among residents of areas closer to competent treatment centers, with the worst building conservation status, a lower percentage of high school and university graduates, and a higher percentage of unemployed, divorced, separated, or widowed residents. Men who were older at the time of their first treatment access; primary users of cocaine, cannabis, and alcohol; had higher education level; and who lived far from competent treatment centers and closer to drug trafficking centers interrupted their treatment earlier. Primary heroin users experienced more SUD treatment encounters. Living in economically and socially disadvantaged areas and near treatment facilities was associated with a higher prevalence, whereas living near drug-dealing centers and far from competent treatment centers was associated with a decrease in treatment retention.

Are Rural Opioid Treatment Program (OTP) Facilities Associated with Lower Deaths?

Objectives: Rural areas have been particularly affected by the opioid epidemic in the U.S., with treatment options being scarce. This study focuses on opioid treatment programs (OTPs), which combine counseling services and opioid-related medication provision. In the South census region (comprised of 16 states and D.C.), 156 urban counties and 27 rural counties contained OTPs as of 2013. We examine whether their presence is associated with lower opioid-related death rates during 2014-2016. Methods: Coarsened exact matching (CEM) is used to match treated and untreated counties on demographic characteristics and opioid-related deaths from 2011 to 2013. Two treatments are considered: (1) if a county had an OTP in 2013; and (2) if an OTP existed in a neighboring county in 2013. The matched samples are then used in weighted least square regression models, with propensity score matching serving as a robustness check. Rural and urban counties are analyzed separately to determine if the impact of OTPs differs between these areas. Results: Results show that the presence of an OTP mostly has no statistical association with the rate of (or change in) future opioid deaths, in either rural or urban counties. Proximity to a neighboring county OTP displays a similar lack of association. Conclusions: The findings suggest that OTPs are not associated with fewer opioid-related deaths in the South over the near term, regardless of rural or urban location. These results could be attributed to outside factors that hinder this relationship. Continued assessment of varied approaches to the rural opioid crisis is encouraged.

Community social deprivation and availability of substance use treatment and mutual aid recovery groups

Background

The spatial distribution of substance use services impacts their use, with greater access to services associated with more positive outcomes. Findings from availability of primary healthcare indicate service shortages exist in areas characterized by social deprivation. This study investigated whether community social deprivation was associated with a lack of availability of substance use treatment or mutual aid recovery support services.

Methods

This is an ecological analysis investigating the availability of substance use services at a community level in the state of New Hampshire. Several public data sources were combined to represent community social deprivation and availability of substance treatment of mutual aid recovery support groups. Principal components analysis and negative binomial regression were used to test the relationship between community structure and the availability of substance use services.

Results

Community social deprivation was characterized by high rates of poverty, no access to motor vehicles, renter-occupied housing, less than a high school degree, and nonemployment. Communities high in measures of social deprivation were associated with increased availability of both substance use treatment and recovery support services.

Conclusions

Contrary to findings in access to primary healthcare services, social disadvantage was positively related to availability for both types of substance use services. This relationship may reflect the stigma associated with substance use where services associated with stigmatized conditions locate in areas with the least resistance to their presence or be a function of affordability of space. Future research could investigate the relationship between access to services and individual client outcomes.

Situational Social Support and Relapse: An Exploration of Compulsory Drug Abuse Treatment Effect in China

The present study explores situational social support of drug abusers during compulsory rehabilitation and provides a preliminary estimation of relationship between social support and relapse. Links between social support and relapse are examined in a study of drug abusers accepting coercive detoxification and rehabilitation treatment, and self-reported relapse in the following 6 months ( N = 535). External and internal social support with abstinence-specific support inclusive are investigated. With certain demographic variables and risk-related variables controlled, greater special type of external social support (as measured by number of children) predicts a lower risk of relapse, which means better effect of compulsory rehabilitation. Participation into some of the institutional programs and experienced personal conflicts for abstinence show no statistically significant with relapse risk.

Collective Efficacy as a Key Context in Neighborhood Support for Urban Youth

Neighborhood context, including the physical and social environment, has been implicated as important contributors to positive youth development. A transactional approach to neighborhood asserts that place and people are mutually constitutive; negative perceptions of place are intrinsically bound with negative portrayals of stigmatized groups, including youth. Adult perceptions of neighborhood youth may contribute to an increased sense of alienation and youth antisocial behavior. This study uses street-intercept interviews with adults (N = 408) to examine the relationship between neighborhood conditions and adult support for neighborhood youth. A path model was used to examine the direct and indirect relationship of neighborhood constructs (safety, aesthetic quality, and walkability) on adult support for neighborhood youth. Neighborhood aesthetic quality and the walking environment were directly associated with adult support for youth, whereas perceived safety was indirectly associated. Collective efficacy partially explained these relationships. Findings support theorized relationships between people and places; improvements to neighborhood physical environment may directly impact resident adults' perceptions of neighborhood young people.

The association between neighborhood socioeconomic disadvantage and high-risk injection behavior among people who inject drugs

BACKGROUND

Although much research has been conducted on the determinants of HIV risk behavior among people who inject drugs (PWID), the influence of the neighborhood context on high-risk injection behavior remains understudied. To address this gap in the literature, we measured associations between neighborhood socioeconomic disadvantage and high-risk injection behavior, and determined whether these associations were modified by drug-related police activity and syringe exchange program (SEP) accessibility.

METHODS

Our sample was comprised of 484 pharmacy-recruited PWID in New York City. Measures of neighborhood socioeconomic disadvantage were created using data from the 2006-2010 American Community Survey. Associations with high-risk injection behavior were estimated using multivariable Poisson regression. Effect modification by drug-related police activity and SEP accessibility was assessed by entering cross-product terms into adjusted models of high-risk injection behavior.

RESULTS

Neighborhood socioeconomic disadvantage was associated with decreased receptive syringe sharing and unsterile syringe use. In neighborhoods with high drug-related police activity, associations between neighborhood disadvantage and unsterile syringe use were attenuated to the null. In neighborhoods with high SEP accessibility, neighborhood disadvantage was associated with decreased acquisition of syringes from an unsafe source.

CONCLUSIONS

PWID in disadvantaged neighborhoods reported safer injection behaviors than their counterparts in neighborhoods that were relatively better off. The contrasting patterns of effect modification by SEP accessibility and drug-related police activity support the use of harm reduction approaches over law enforcement-based strategies for the control of blood borne virus transmission among PWID in disadvantaged urban areas.

Health in the Tenderloin: A resident-guided study of substance use, treatment, and housing

Substance use researchers recognize that environments - our homes, streets, communities, and neighborhoods - set the stage for substance use and treatment experiences by framing interactions, health options, and decision-making. The role of environment is particularly salient in places deemed disadvantaged or risky, such as parts of the Tenderloin neighborhood of San Francisco. Since risk is historically, socially, and structurally situated, an individual's social position in a neighborhood shapes how risk environments are experienced. The purpose of this study was to explore how the environment shapes substance use and treatment experiences, described from the perspective of Tenderloin residents. I conducted docent method interviews with formerly homeless women living in supportive housing in San Francisco (N = 20). The docent method is a three-stage, participant-led, audiotaped, and photographed walking interview. As they guided me through target "sites of interest" (homes, streets, treatment programs, and safe spaces), participants discussed their experiences with substance use and treatment in the environment. First, they described that the risks of a broader drug market are concentrated in the Tenderloin, exposing residents to elevated and disproportionate risk. Second, for structural, economic, social, and physical reasons, participants described a sense of geographic or neighborhood stratification. Third, multiple levels of policing and surveillance were persistent, even in participants' homes. Fourth, despite all the challenges, participants found security and support in the Tenderloin, and considered it their home. In the discussion, I offer that the Tenderloin environment provided residents many advantages, but forms of structural and everyday violence largely defined their experiences in the neighborhood.

Triangulating Syndemic Services and Drug Treatment Policy: Improving Drug Treatment Portal Locations in Baltimore City

THE PROBLEM

The prevalence of injection drug use (IDU) and incidence of human immunodeficiency virus (HIV) remain high in Baltimore, where IDU is a primary HIV risk factor. Substance use disorders and HIV are related syndemically--their causes and consequences interact synergistically. Baltimore is increasingly considering the syndemic relationship of substance use disorders, IDU, and HIV in making decisions about drug treatment funding and location.

PURPOSE OF ARTICLE

Our goal was to empirically identify the optimal location of new drug treatment programs through the development and application of a novel, practical tool.

KEY POINTS

Syndemic triangles were constructed to measure and visualize unmet need for drug treatment services. These data were used to determine priority zones for new treatment centers.

CONCLUSIONS

The application of this tool helped inform strategies for locating drug treatment services in Baltimore, and its successful use suggests its potential value in other metropolitan areas.

Perceived neighborhood safety, recovery capital, and successful outcomes among mothers 10 years after substance abuse treatment

This study examines perceived neighborhood characteristics associated with successful outcome among mothers 10 years after being treated for substance use disorders. Data were obtained from 713 mothers first studied at admission to drug treatment in California in 2000-2002 and followed up in 2009-2011. At follow-up, 53.6% of mothers had a successful outcome (i.e., no use of illicit drugs and not involved with the criminal justice system). Perceived neighborhood safety almost doubled the odds of success. Perceived neighborhood safety interacted with social involvement, decreasing the odds of success among mothers who reported more versus less neighborhood social involvement. Perceived neighborhood climate is associated with long-term outcomes among mothers with substance use disorders independent of individual-level characteristics, underscoring the need for further efforts to understand its interaction with recovery capital in ways that promote and impede health.

Spatial accessibility of drug treatment facilities and the effects on locus of control, drug use, and service use among heroin-injecting Mexican American men

BACKGROUND

This study explores the spatial accessibility of outpatient drug treatment facilities and the potential relationship with drug use-related outcomes among Mexican American heroin users.

METHODS

Secondary data on 219 current and former heroin-injecting Mexican American men aged 45 and older were drawn from a research study in Houston, Texas. We used geographic information systems (GIS) to derive two spatial accessibility measures: distance from one's place of residence to the closest drug treatment facility (in minutes); and the number of facilities within a 10-minute driving distance from one's place of residence. Exploratory logistic regression analyses examined the association between the spatial accessibility of drug treatment facilities and several drug use-related outcomes: internal locus of control (LOC); perceived chances and worries of injecting in the next six months; treatment utilization; and location of last heroin purchase.

RESULTS

Participants with greater spatial access to treatment programs were more likely to report a higher chance of injecting in the near future. However, while current heroin users were more worried about injecting in the next six months, greater spatial access to treatment programs seemed to have a buffering effect. Finally, those who lived closer to a treatment programs were more likely to have last purchased heroin inside the neighborhood versus outside the neighborhood. Spatial accessibility was not associated with internal LOC or treatment utilization.

CONCLUSION

The findings showed that the presence of outpatient treatment facilities-particularly services in Spanish-may influence perceived risk of future heroin use and purchasing behaviors among Mexican American men. Implications for future spatially-informed drug use research and the planning of culturally and linguistically responsive drug treatment programs are discussed.

Community context and healthcare quality: the impact of community resources on licensing and accreditation of substance abuse treatment agencies

This study examines variation in healthcare quality among substance abuse treatment agencies. Using an organizations framework, the authors predict that resource advantages benefit certain types of healthcare organizations, especially those located in affluent communities. As a result, levels of licensing and accreditation of substance abuse treatment agencies will differ across United States counties. The authors model these resources at both the organizational and community levels in an effort to understand the variability of licensing and accreditation between agencies and their local contexts. In multivariate models, the findings confirm that organizational characteristics such as private ownership (compared to public ownership), managed care contracts, inpatient and residential programs (compared to outpatient settings), as well as socioeconomic, racial/ethnic, and healthcare system advantage promote higher levels of licensing and accreditation. Public ownership and outpatient settings, as well as socioeconomic, racial/ethnic, and healthcare system disadvantage, are associated with lower levels of licensing and accreditation.

A spatial analysis of community disadvantage and access to healthcare services in the U.S

Ongoing socioeconomic and racial and ethnic gaps in access to healthcare make it vital to examine the relationship between characteristics of communities and their impact on the availability of healthcare services. This study investigates how community-based resource constraints influence the provision of healthcare services in the United States. Drawing on several theoretical frameworks including research in the spatial distribution of healthcare, we compile data on 3141 U.S. counties in order to investigate the argument that gaps in the provision of substance abuse treatment are a function of resource constraints experienced by disadvantaged communities. Our principal aim is to demonstrate that socioeconomic privation, racial and ethnic isolation and limited healthcare infrastructure constrain the provision of substance abuse treatment services. Since prior research shows spatial clustering of socioeconomic privation, racial and ethnic isolation, and healthcare resources, we explicitly model the spatial dimensions of community-based resource disadvantage. Central findings support our chief expectations: counties with greater socioeconomic privation and diminished healthcare infrastructure experienced limited access to substance abuse treatment. Moreover, treatment clusters themselves were significantly related to socioeconomic privation and diminished healthcare infrastructure. Counties with a higher proportion of racial and ethnic minority members, however, did not experience less access to substance abuse treatment, with one exception, although post hoc analyses showed poverty had a moderating effect on race and ethnicity. Study limitations and implications for the organization of treatment resources are discussed.

Treatment Facility Neighborhood Environment and Outpatient Treatment Completion

The current study focuses on three dimensions of treatment neighborhood environments that may influence treatment retention: neighborhood disadvantage, stability, and concentrated immigration. We examined treatment outcomes for a total of 9,319 individuals who were admitted for initial treatment in 56 outpatient clinics in Cook County, Illinois. Census-tract-level data were used to measure facility neighborhood environment. We found that neighborhood disadvantage was unrelated to individual treatment completion. Immigrant concentration was found to increase the likelihood of substance abuse treatment completion, although it was attenuated after controlling for patient problem severity and referral sources. Neighborhood stability was found to be positively related to treatment completion. These results suggest that knowledge of neighborhood context should be an important consideration when making placement decisions of new treatment facilities. Knowledge of neighborhood impact on treatment attrition should also be considered essential information to be used for client placement, treatment program design, and discharge protocols.

A multilevel analysis of regional and individual effects on methadone maintenance treatment in Taiwan

OBJECTIVE

This study evaluated the direct and interactive effects of regional-level and individual-level characteristics on methadone maintenance treatment (MMT), after considering the individual characteristics in Taiwan.

METHODS

This study utilized a survey research method. Opioid-dependent patients who participated in the outpatient MMT program in 2009 and met the eligibility criteria were recruited from five hospitals. The impact of MMT on self-perceived health was assessed by using questionnaires. This study assessed the participants' quality of life and treatment outcomes during 3-month follow-up visits, before evaluating the direct effects of regional and individual characteristics. Multilevel linear models were used to estimate whether regional levels influenced individual behavior and treatment outcomes.

RESULTS

Three hundred thirty-four opioid-dependent patients agreed to participate in this study. After the follow-up period, 127 participants completed the study (completion rate = 38%). Participants receiving MMT demonstrated significant improvements in psychological state, HIV risk-taking behavior, social functioning, and health. Regional characteristics, such as the lower than junior high school rate, low-income family rate, and related crime rates, of the study regions were negatively associated with improvements in drug abuse behavior.

CONCLUSIONS

This study shows that MMT can significantly improve the HIV risk-taking behavior and health of the study participants. Disadvantaged regions, however, exhibit poor treatment outcomes. This study suggests actions to minimize the treatment variations between regions.

Neighborhood poverty and injection cessation in a sample of injection drug users

Neighborhood socioeconomic environment may be a determinant of injection drug use cessation. The authors used data from a prospective cohort study of Baltimore City, Maryland, injection drug users assessed between 1990 and 2006. The study examined the relation between living in a poorer neighborhood and the probability of injection cessation among active injectors, independent of individual characteristics and while respecting the temporality of potential confounders, exposure, and outcome. Participants' residences were geocoded, and the crude, adjusted, and inverse probability of exposure weighted associations between neighborhood poverty and injection drug use cessation were estimated. Weighted models showed a strong association between neighborhood poverty and injection drug use cessation; living in a neighborhood with fewer than 10%, compared with more than 30%, of residents in poverty was associated with a 44% increased odds of not injecting in the prior 6 months (odds ratio = 1.44, 95% confidence interval: 1.14, 1.82). Results show that neighborhood environment may be an important determinant of drug injection behavior independent of individual-level characteristics.
