Abstract
Violence against women (VAW) is a significant public health and human rights issue, with an estimated 736 million women globally experiencing VAW. Consistent evidence demonstrates that substance use is associated with VAW and that participation in substance use treatment programs is associated with reduction in substance use-related violence. While evidence demonstrates the ability to address VAW through substance use treatment programs, less attention has been paid to geographic access to substance use programs. If these programs are geographically inaccessible, particularly to marginalized populations, many people will not get the help they need. This study seeks to explore the relationship between geographic access to substance use treatment programs on VAW. Using data from the HIV Prevention Trials Network (HPTN) 064 study, longitudinal multilevel models were used to assess the relationship between neighborhood-level social determinants, with a specific focus on geographic access to Substance Abuse and Mental Health Services Administration (SAMHSA) certified drug and alcohol treatment programs and VAW. The study included 1910 women, ages 18 to 44, living in select geographic areas with high-ranked prevalence of HIV and poverty. The findings of this study indicate that among women who reside in census tracts with high prevalence rates of HIV: (1) substance use increases VAW; (2) VAW decreases as geographic access to SAMHSA-certified drug and alcohol treatment facilities increases; and (3) when looking at specific types of VAW, emotional and physical abuse decreases as geographic access to substance use treatment increases. Policies and programs to increase access to substance use treatment should be explored and evaluated, and more programs are needed that address the intersectionality of substance use and VAW.

Abstract
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.

Abstract
Behavioral health disorders such as mental disorders (MD) and substance use disorders (SUD) are epidemics in the US; however, the availability of treatment and prevention services remains low. This study assessed neighborhood-level sociodemographic attributes to characterize the availability of behavioral health treatment facilities in Florida. The American Community Survey and SAMHSA's Behavioral Health Treatment Locator were used to identify behavioral health treatment facilities in Florida and calculate their density by census tract. Spatial lag regression models were used to assess census tract-level correlates of facility density for 390 MD treatment facilities, 518 SUD facilities, and subsets of affordable MD and SUD facilities. Behavioral health treatment facility density was negatively associated with rurality and positively associated with the proportion of non-Latino Black, Latino, insured, and college-educated populations. Stark rural-urban disparities in behavioral health treatment availability present opportunities to prioritize telehealth and mobile interventions and improve treatment utilization.

Abstract
BACKGROUND Commuting time to treatment has been shown to affect healthcare outcomes such as engagement and initiation. The purpose of this study is to extend this line of research to investigate the effects of driving time to opioid programs on treatment outcomes. METHODS We analyzed discharge survey data from 22,587 outpatient opioid use disorder treatment episodes (mainly methadone) in Los Angeles County and estimated the associated driving time to each episode using Google Maps. We used multivariable logistic regressions to examine the association between estimated driving time and odds of treatment completion after adjusting for possible confounders. RESULTS Findings show an average driving time of 11.32 min and an average distance of 11.18 km. We observed differences in estimated driving time across age, gender, and socioeconomic status. Young, male, less formally educated, and Medi-Cal-ineligible clients drove longer to treatment. A 10-min drive was associated with a 33% reduction in the completion of methadone treatment plans (p < .01). CONCLUSION This systemwide analysis provides novel time estimates of driving-based experiences and a strong relationship with completion rates in methadone treatment. Specifically, the result showing reduced treatment completion rates for drive times longer than 10 min may inform policies regarding the ideal geographic placement of methadone-based treatment programs and service expansion initiatives.

Limited treatment accessibility: Implications for alcohol treatment disparities among Mexican Americans living in the U.S.-Mexico border region. J Subst Abuse Treat 2020; 121:108162. [PMID: 33172725 DOI: 10.1016/j.jsat.2020.108162] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Revised: 09/12/2020] [Accepted: 10/05/2020] [Indexed: 11/26/2022]
Abstract
PURPOSE Receipt of alcohol-related care for alcohol use is particularly low among those residing in the U.S.-Mexico border region. One reason for this disparity may be limited treatment accessibility, making it difficult for those who need it to access needed treatment. The current study assesses whether differences in treatment utilization are mediated by differences in treatment accessibility in cities within and outside of the border region. METHODS We used data from the U.S.-Mexico Study of Alcohol and Related Conditions involving a probability sample of Mexican-origin adults surveyed in three cities in Texas (2011-2013). We included only participants with a lifetime history of alcohol use disorder (AUD) (n = 792). We examined two lifetime measures of self-reported alcohol treatment utilization: considering getting help for an alcohol problem and receipt of treatment. We geocoded locations of facilities listed in the SAMHSA National Directory of Drug and Alcohol Abuse Treatment Facilities. We considered three types of facilities: any outpatient treatment, programs offering fee assistance, and programs offering Spanish-language services. We measured treatment accessibility by density of treatment (i.e., number of facilities within a 20-mile radius of participant's residence) and proximity to treatment (i.e., travel time to nearest facility). We assessed direct and indirect effects of two cities in the border region (versus one nonborder city) on the outcomes through treatment accessibility using generalized structural equation models that accounted for clustering of respondents in cities and in neighborhoods, weighted for sampling and nonresponse and adjusted for covariates. RESULTS Of 792 respondents with lifetime AUD, 22% had considered getting help and 11% had received treatment, with consideration of getting help being less likely in cities in the border region. We observed no significant differences in treatment receipt across cities. Reduced densities of all three types of treatment programs were significant mediators for the effect of residing in a border region on considering getting help. Time to nearest Spanish-language program also mediated the effect of residing in a border region on considering getting help for one city. CONCLUSIONS Border cities had lower density of treatment and because treatment density was positively associated with considering getting help, residence in a city in the border region was associated with lower odds of considering getting help, regardless of type of treatment. These findings suggest increasing the number of treatment locations available within cities along the U.S.-Mexico border may encourage those with AUD to consider getting help.

Do benefits restrictions limit Medicaid acceptance in addiction treatment? Results from a national study. J Subst Abuse Treat 2018; 87:50-55. [PMID: 29471926 DOI: 10.1016/j.jsat.2018.01.010] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2017] [Revised: 01/11/2018] [Accepted: 01/12/2018] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To assess the relationship of restrictions on Medicaid benefits for addiction treatment to Medicaid acceptance among addiction treatment programs. DATA SOURCES We collected primary data from the 2013-2014 wave of the National Drug Abuse Treatment System Survey. STUDY DESIGN We created two measures of benefits restrictiveness. In the first, we calculated the number of addiction treatment services covered by each state Medicaid program. In the second, we calculated the total number of utilization controls imposed on each service. Using a mixed-effects logistic regression model, we estimated the relationship between state Medicaid benefit restrictiveness for addiction treatment and adjusted odds of Medicaid acceptance among addiction treatment programs. DATA COLLECTION Study data come from a nationally-representative sample of 695 addiction treatment programs (85.5% response rate), representatives from Medicaid programs in forty-seven states and the District of Columbia (response rate 92%), and data collected by the American Society for Addiction Medicine. PRINCIPAL FINDINGS Addiction treatment programs in states with more restrictive Medicaid benefits for addiction treatment had lower odds of accepting Medicaid enrollees (AOR = 0.65; CI = 0.43, 0.97). The predicted probability of Medicaid acceptance was 35.4% in highly restrictive states, 48.3% in moderately restrictive states, and 61.2% in the least restrictive states. CONCLUSIONS Addiction treatment programs are more likely to accept Medicaid in states with less restrictive benefits for addiction treatment. Program ownership and technological infrastructure also play an important role in increasing Medicaid acceptance.

Abstract
Elevated HIV prevalence has been observed among urban U.S. individuals who use drugs and who lack stable housing. This article synthesizes extant research on this population and situates it in a multilevel, ecologically based model of HIV risk. Based on a multidisciplinary review of the literature, the model applies social-ecological theory on human development to identify factors shaping the HIV risk context for individuals who use drugs and who are unstably housed at global, societal, neighborhood, household, and individual levels of influence. At the global level, the model includes neoliberal ideologies contributing to the social inequalities that frame the HIV epidemic. U.S. housing and drug policy, including urban renewal, HOPE VI, and the War on Drugs, is the focus of the societal level. At the neighborhood level, mechanisms of the built environment and psychosocial mechanisms are explored for their salience to HIV risk. Research on the association between housing instability and HIV risk is reviewed at the household level. At the last level, relevant individual differences in biology, psychology, and cognition are discussed. Modeling risk at multiple levels of the environment underscores the need to expand the focus of research, treatment, and prevention interventions for HIV/AIDS and addictions beyond individuals and their risk behaviors to address facets of structural violence and incorporate the broader social, political, and economic contexts of risk and health.

Abstract
PURPOSE Little qualitative research has examined factors associated with care in substance abuse treatment agencies in Southeastern rural communities. This study explored client- and agency stakeholder-perceived barriers and facilitators to substance use treatment delivery in southeastern rural communities. METHODS Group and individual interviews were conducted with 40 key stakeholders and 40 clients at 9 substance abuse agencies serving rural communities in a southeastern state. Qualitative thematic analysis was used to identify perceived barriers and facilitators to substance abuse services in rural communities. FINDINGS Four primary themes emerged from the client and stakeholder interviews as both barriers and facilitators: availability of services for individuals with substance use disorders; access to the current technology for client services and agency functioning; cost of services; and stigma. CONCLUSIONS This study identifies novel barriers and facilitators to substance use care in the rural South and highlights essential areas for consideration when developing and implementing substance use care in this geographic region. These findings can be used as guidelines to provide better care to individuals with substance use disorders living in rural communities.

Abstract
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.

Abstract
Background The high prevalence of mental health issues among clients attending substance abuse treatment (SAT) has pressured treatment providers to develop integrated substance abuse and mental health care. However, access to integrated care is limited to certain communities. Racial and ethnic minority and low-income communities may not have access to needed integrated care in large urban areas. Because the main principle of health care reform is to expand health insurance to low-income individuals to improve access to care and reduce health disparities among minorities, it is necessary to understand the extent to which integrated care is geographically accessible in minority and low-income communities. Methods National Survey of Substance Abuse Treatment Services data from 2010 were used to examine geographic availability of facilities offering integration of mental health services in SAT programs in Los Angeles County, California. Using geographic information systems (GIS), service areas were constructed for each facility (N = 402 facilities; 104 offering integrated services) representing the surrounding area within a 10-minute drive. Spatial autocorrelation analyses were used to derive hot spots (or clusters) of census tracts with high concentrations of African American, Asian, Latino, and low-income households. Access to integrated care was reflected by the hot spot coverage of each facility, i.e., the proportion of its service area that overlapped with each type of hot spot. Results GIS analysis suggested that ethnic and low-income communities have limited access to facilities offering integrated care; only one fourth of SAT providers offered integrated care. Regression analysis showed facilities whose service areas overlapped more with Latino hot spots were less likely to offer integrated care, as well as a potential interaction effect between Latino and high-poverty hot spots. Conclusion Despite significant pressure to enhance access to integrated services, ethnic and racial minority communities are disadvantaged in terms of proximity to this type of care. These findings can inform health care policy to increase geographic access to integrated care for the increasing number of clients with public health insurance.

Abstract
BACKGROUND Travel distance and English proficiency skills are widely recognized factors associated with service access and treatment engagement. As Latino populations represent one of the most rapidly growing populations in the United States, methods are needed to better understand availability of linguistically appropriate services in Latino communities. Given regional variability in the density of Latino communities, the current study examines treatment access as travel distance to outpatient substance use disorder treatment facilities in one of the largest and most rapidly changing Latino communities in the United States - Los Angeles County, CA. METHODS Data from the 2010 U.S. Census and the National Survey of Substance Abuse Treatment Services were analyzed using a geographic information system approach to determine the street-level distance between treatment facilities with services in Spanish and Latino communities throughout L.A. County. This study used an innovative approach that included network analysis and spatial autocorrelation to identify "hot spots," i.e. clusters of census tracts with high-density Latino populations that were relatively far from treatment services in Spanish. RESULTS The analysis identified several key hot spots with significantly large Latino populations and far street distances to the closest facility offering Spanish-language services. The average distance between these hot spots and the closest facilities was 2.74 miles (SD=0.38), compared to a county average of 2.28 miles (SD=2.60). In several key hot spots, the distance was greater than 3 miles. CONCLUSION Despite the growing presence of Latinos in L.A. County in 2010, constrained access to services in Spanish was found in geographic locations highly represented by Latinos. The distances identified in this study are almost triple the 1-mile threshold representing reduced access to treatment as determined by other studies. Geographic information systems represent an innovative and user-friendly approach for effectively and efficiently identifying areas with the greatest service needs. This approach can inform policies to increase the capacity of ethnic minority communities to develop linguistically responsive social services.

Abstract
Background The percentage of Latino clients entering outpatient substance abuse treatment (OSAT) in the United States has increased significantly in the past 10 years. Evidence suggests that a lack of services in Spanish is a significant barrier to treatment access among Latinos. Methods Using a geographic information system (GIS) approach, data from the U.S. Census Bureau and the National Survey of Substance Abuse Treatment Services (N-SSATS) were analyzed to determine the geographic distance between OSAT facilities with services in Spanish and Latino communities throughout Los Angeles County, CA. Data from N-SSATS were also analyzed using logistic regression models to examine organizational characteristics and their association with offering services in Spanish. Our GIS methods are tested in their ability to provide baseline measures to inform future analysis comparing changes in demography and service infrastructure. Results GIS analysis revealed cold spots representing high-density Latino communities with extensive travel distance to facilities offering services in Spanish. The average linear distance between Latino communities and facilities offering Spanish-language services ranged from 2 to 6 miles, while the location of the cold spots pointed to a need for services in Spanish in a particular subregion of the county. Further, secondary data analysis revealed that, on average, being privately owned (OR = .23, 95% CI = 0.06-0.90) was associated with a lower likelihood of providing services in Spanish compared to public facilities. Additionally, a facility with a state license (OR = 2.08, 95% CI = 1.12-3.88) or a higher number of Medicaid recipients (OR = 2.98, 95% CI = 1.76-5.05) was twice as likely to offer services in Spanish. Conclusion Despite the significant presence of Latinos in L.A. County in 2000, low capacity was found in discrete Latino communities in terms of offering OSAT services in Spanish. Funding and regulation play a significant role in facilities' capacity to offer these services. Future studies should build from our multi-method approach to compare changes in population demography and system infrastructure and inform health care policy that seeks to improve providers' capacity to provide linguistically competent care.
