Outpatient substance abuse treatment completion rates for racial-ethnic minorities during the Great Recession

There has been minimal research linking the effects on racial-ethnic minorities’ health outcomes, particularly research focused on racial-ethnic minorities seeking outpatient substance abuse treatment in the United States. The Great Recession from December 2007 to June 2009 in the United States provides the backdrop against the completion of substance abuse treatments among racial-ethnic minorities that may be associated with the impacts on users’ social realities. We utilized data from the 2006–2011 Treatment Episode Datasets–Discharge (TEDS-D) dataset which collects data on outpatient substance abuse treatment institutions throughout the United States. The substance abuse treatment completion rates were higher prior to the Great Recession and lower following the Great Recession. Hispanics were more likely than non-Hispanic whites to complete substance abuse treatment, while other minority groups such as Non-Hispanic Blacks, were less likely to do so. Clients in the Northeast and West regions were more likely to successfully complete substance abuse treatment than those in the South. These findings have implications for impacting outpatient substance abuse treatment completion rates following the Great Recession to reduce racial-ethnic disparities which were impacted by region. Even amid an economic recession, treatment for substance abuse should continue to be a top concern.

Racial/Ethnic Disparities in Treatment Completion for Youths with and without a Psychiatric Comorbidity

The current study sought to examine the comorbidity of substance misuse and a mental health problem among adolescents and young adults, aged 15–24. It also sought to examine racial/ethnic disparities in substance abuse treatment completion among non-Hispanic White, African American, and Hispanic youths with and without a psychiatric comorbidity. The 2014 Treatment Episode Data Set – Discharges (TEDS-D) was used (N = 207,578). Results show that 32.6% of youths entering substance abuse treatment had a psychiatric problem and only 34.8% of all youths completed treatment. Racial/ethnic disparities were found between youths with and without a psychiatric comorbidity in treatment completion.

The Assessment of Recovery Capital (ARC) predicts substance abuse treatment completion

Recovery from addiction requires various personal and environmental resources. The purposes of this study were to determine if the Assessment of Recovery Capital (ARC) scores measured at admission could predict substance abuse treatment (SAT) completion and to identify personal and environmental factors associated with ARC scores. Participants (N = 2265) comprised clients entering a Midwestern SAT facility (August 2015 – June 2017). Logistic regression was used to predict SAT completion using ARC scores. Nonparametric group comparisons were used for personal and environmental covariates. ARC scores significantly predicted successful SAT completion (OR = 1.05, 95% CI = 1.04, 1.05, Wald z = 12.9, p < 0.001). Employment had a positive relationship with ARC scores (Kruskal-Wallis χ2 = 215.96, df = 8, p < 0.001). ARC scores varied according to primary substance (Kruskal-Wallis χ2 = 101.10, df = 6, p < 0.001); alcohol and marijuana showed the highest scores and heroin the lowest. ARC scores decreased as number of problem substances increased (Kruskal-Wallis χ2 = 70.57, df = 2, p < 0.001, rS = –0.163, p < 0.001). Living arrangement was also significant (Kruskal-Wallis χ2 = 146.36, df = 8, p < 0.001); clients who were homeless had the lowest ARC scores. A number of personal and environmental covariates were associated with the ARC scores and potentially with the outcome. After adjustment, the ARC remained a strong predictor of SAT completion. The ARC should be used in SAT facilities to guide treatment decisions and to create individualized treatment plans for clients.

Factors Contributing to Substance Misuse Treatment Completion among Native Hawaiians, Other Pacific Islanders, and Asian Americans

Background: Research on substance abuse treatment completion (SATC) among Asian Americans and Native Hawaiian and Other Pacific Islanders (NHOPIs) is extremely limited despite growing concern of SA among these groups. Objectives: This study examined predictors of SATC among and within Asian, NHOPI, and White racial groups. Methods: 129,939 cases from the SA and Mental Health Services, Treatment Episode Data Set-Discharges-2016 were used in this study. Logistic regressions were employed to examine the differential impact of race on SATC and to investigate the moderating effect of race on the relationship between socioeconomic factors, type of substance used, and type of treatment setting on SATC. Results: NHOPIs were less likely to complete SA treatment than Whites. Within-group analysis indicated that NHOPIs who were in outpatient non-intensive treatment were more likely to complete treatment compared to ones in inpatient (more than 30 days), and outpatient intensive settings. In contrast, Asians and Whites in outpatient non-intensive treatment settings were less likely to complete compared to all other types of treatment settings. Older adults for Whites were more likely to complete treatment compared with younger adults. Age was not a significant predictor of SATC for Asians and NHOPIs. Asian and NHOPI methamphetamine users were less likely to complete treatment compared with White users. Conclusion/Importance: Findings highlight the importance of disaggregating Asians and NHOPIs in future SA studies to better understand how specific factors are relevant to each group, and to guide the development of cultural and race-informed treatments for these groups.

Substance abuse treatment engagement, completion and short-term outcomes in the Western Cape province, South Africa: Findings from the Service Quality Measures Initiative

BackgroundOptimizing the effectiveness of substance use disorder (SUD) treatment is critical in low-and middle-income countries (LMICs) with limited opportunities for SUD treatment. This is the first study to identify targets for interventions to improve the quality of SUD treatment in a LMIC. MethodWe explored correlates of three indicators of treatment quality (treatment engagement, completion and abstinence at treatment exit) using data from a SUD performance measurement system implemented in the Western Cape Province of South Africa. The sample included data from 1094 adult treatment episodes representing 53% of the treatment episodes in 2016. Using multivariate logistic regression analyses, we modeled socio-demographic, substance use and program correlates of treatment engagement, completion, and abstinence at treatment exit. ResultsOverall, 59% of patients completed treatment (48% of patients from outpatient services). Treatment completion was associated with greater likelihood of abstinence at treatment exit. Patients were more likely to complete treatment if they engaged in treatment, were older, and had more severe drug problems (characterized by daily drug use and heroin problems) and attended programs of shorter duration. Residential treatment was associated with greater likelihood of treatment engagement, completion, and abstinence at treatment exit. ConclusionImproving rates of outpatient treatment completion will enhance the effectiveness of South Africa’s SUD treatment system. Interventions that promote engagement in treatment, particularly among younger patients; reduce program length through referral to step-down continuing care; and ensure better matching of drug problem to treatment level and type could improve rates of treatment completion.

Machine Learning of Functional Magnetic Resonance Imaging Network Connectivity Predicts Substance Abuse Treatment Completion

BackgroundSuccessfully treating illicit drug use has become paramount, yet elusive. Devising specialized treatment interventions could increase positive outcomes, but it is necessary to identify risk factors of poor long-term outcomes to develop specialized, efficacious treatments. We investigated whether functional network connectivity (FNC) measures were predictive of substance abuse treatment completion using machine learning pattern classification of functional magnetic resonance imaging data. MethodsTreatment-seeking stimulant- or heroin-dependent incarcerated participants (n = 139; 89 women) volunteered for a 12-week substance abuse treatment program. Participants performed a response inhibition Go/NoGo functional magnetic resonance imaging task prior to onset of the substance abuse treatment. We tested whether FNC related to the anterior cingulate cortex would be predictive of those who would or would not complete a 12-week substance abuse treatment program. ResultsMachine learning pattern classification models using FNC between networks incorporating the anterior cingulate cortex, striatum, and insula predicted which individuals would (sensitivity: 81.31%) or would not (specificity: 78.13%) complete substance abuse treatment. FNC analyses predicted treatment completion above and beyond other clinical assessment measures, including age, sex, IQ, years of substance use, psychopathy, anxiety and depressive symptomatology, and motivation for change. ConclusionsAberrant neural network connections predicted substance abuse treatment outcomes, which could illuminate new targets for developing interventions designed to reduce or eliminate substance use while facilitating long-term outcomes. This work represents the first application of machine-learning models of FNC analyses of functional magnetic resonance imaging data to predict which substance abusers would or would not complete treatment.

A Post-Hurricane Katrina Examination of Substance Abuse Treatment Discharges With Co-Occurring Psychiatric and Substance Use Disorders

ABSTRACTObjectives: There is increasing literature supporting the adverse effects of disasters on substance use and psychiatric disorders. The co-occurrence of psychiatric disorders with substance use intensifies the challenge of treatment delivery. Thus the aim of this study was to examine the prevalence of substance use, treatment characteristics, and demographics of discharges from substance abuse treatment in New Orleans, post–Hurricane Katrina. Trends associated with discharges that have a co-occurring psychiatric and substance use disorder (COD) were also assessed. The secondary aim of this study was to examine the association of successful substance abuse treatment completion among those with a COD post–Hurricane Katrina. Methods: Substance abuse treatment discharge data (N = 16,507) from New Orleans, Louisiana, for years 2006 through 2011 were obtained from the Treatment Episode Data Set–Discharge. Multiple logistic regression analysis was employed to examine the association of discharges with a COD and completion of substance abuse treatment. Demographic, psychiatric, and treatment characteristics of discharges in 2006 were compared to characteristics in 2011. Trends of characteristics were also assessed through the study period. Results: Roughly a third (35.2%) of all discharges in New Orleans from 2006 to 2011 had a COD. After controlling for race, employment, treatment service setting at discharge, primary substance problem, and the discharge's principal source of referral, discharges with a COD were 29% less likely to complete treatment as compared to those with no COD (AOR = 0.71, 95% CI [0.56, 0.90], p = .004). Treatment completion among discharges with a COD has significantly declined from 36.8% in 2006 to 18.7% in 2011 (p < .0001). Notable significant trends in homelessness, criminality, and heroin use were identified among discharges with a COD. Conclusions: Substance abuse treatment undergoes various changes in the event of a natural disaster. These changes may increase challenges for successful treatment completion for vulnerable populations such as those with a COD. Results of this study demonstrate that discharges with a COD are less likely to complete treatment as compared to those with no COD disorder. Unmet treatment needs may also increase odds of criminalization and homelessness.

The Role of Familismo and Acculturation as Moderators of the Association Between Family Conflict and Substance Abuse on Latino Adult Males.

The significant research gap on Latino adults who completed substance abuse treatment (SAT) impacts the provision of substance use prevention and treatment for this population. Given the need for culturally-appropriate SAT for Latinos, research that examines the role of cultural constructs and acculturation in relation to substance use behavior is warranted. The purpose of the present study is to test, based on the social control theory, a multiple moderation model using the PROCESS macro1 to examine the moderating effect of Familismo on the association between history of family conflict and years of substance abuse on Latino males who completed SAT at different levels of acculturation (i.e., cultural orientation). Generational status (i.e., immigrant, U. S. born) and age are used as covariates. A total of 117 Latino male participants (Mage= 37, 54% non-U.S. born with a mean length of stay of 19 years in the U.S.) who completed SAT from facilities located in the metropolitan area of Chicago completed self-report measures. Results from the multiple moderation analysis showa significant three-way interaction (family conflict × Familismo × acculturation), indicating that participants with Latino and bicultural orientation who endorse average to high levels of Familismo have fewer years of substance abuse compared to those with U.S. mainstream culture orientation and low Familismo. Findings illustrate the need for SAT that assesses for family conflict and integrates cultural aspects to reduce substance use behavior on Latino males.

Psychosocial Factors Associated with Substance Abuse and Anxiety on Immigrant and U.S. Born Latinos.

Latinos are exposed to adverse psychosocial factors that impact their health outcomes. Given the heterogeneity and rapid growth of this population, there is an urgent need to understand the mechanisms through which psychosocial factors impact substance abuse and anxiety between immigrant and U.S. born Latino adults. The present study employs a multi-group path analysis using Mplus 7.2 to examine generational differences in the paths between affiliation culture, years of formal education, contact with important people, and length of full-time employment to substance abuse and anxiety in immigrant and U.S. born Latino adults who completed substance abuse treatment. A total of 131 participants (Mage= 36.3, SD ± 10.5, 86.3% males, 48.1% non-U.S. born with a mean length of stay of 19 years in the U.S. (SD ± 13.71) in recovery from substance abuse completed self-report measures. Results from the multi-group path analysis suggest that being more affiliated to the U.S. culture is associated with substance abuse, whereas years of formal education and longer full-time employment is associated with reduced anxiety in the immigrant group. Conversely, frequent contact with important people and affiliation to the U.S. culture are associated with fewer years of substance abuse, whereas longer full-time employment is associated with substance abuse in the U.S. born group. Anxiety and substance abuse was correlated only in the U.S. born group. The implications of these findings are discussed.

Brain potentials predict substance abuse treatment completion in a prison sample.

IntroductionNational estimates suggest that up to 80% of prison inmates meet diagnostic criteria for a substance use disorder. Because more substance abuse treatment while incarcerated is associated with better post‐release outcomes, including a reduced risk of accidental overdose death, the stakes are high in developing novel predictors of substance abuse treatment completion in inmate populations.MethodsUsing electroencephalography (EEG), this study investigated stimulus‐locked ERP components elicited by distractor stimuli in three tasks (VO‐Distinct, VO‐Repeated, Go/NoGo) as a predictor of treatment discontinuation in a sample of male and female prison inmates. We predicted that those who discontinued treatment early would exhibit a less positive P3a amplitude elicited by distractor stimuli.ResultsOur predictions regarding ERP components were partially supported. Those who discontinued treatment early exhibited a less positive P3a amplitude and a less positive PC4 in the VO‐D task. In the VO‐R task, however, those who discontinued treatment early exhibited a more negative N200 amplitude rather than the hypothesized less positive P3a amplitude. The discontinuation group also displayed less positive PC4 amplitude. Surprisingly, there were no time‐domain or principle component differences among the groups in the Go/NoGo task. Support Vector Machine (SVM) models of the three tasks accurately classified individuals who discontinued treatment with the best model accurately classifying 75% of inmates. PCA techniques were more sensitive in differentiating groups than the classic time‐domain windowed approach.ConclusionsOur pattern of findings are consistent with the context‐updating theory of P300 and may help identify subtypes of ultrahigh‐risk substance abusers who need specialized treatment programs.

Testing a Multidimensional Acculturation Model on Latinos who Completed Substance Abuse Treatment

Disparities in substance abuse treatment (SAT) utilization and completion suggest that traditional substance abuse models may fall short of addressing the complex needs of Latinos, increasing the odds of relapsing. The need for substance use models that integrate multiple acculturation domains in relation to substance abuse is warranted. The goal of the present study is twofold: a) test a multidimensional acculturation model on Latinos who completed SAT; and b) examine the association between the proposed multidimensional acculturation and days consuming alcohol and illicit drugs in the past six months. A total of 131 participants (Mage=36.15, SD ± 10.5, 86.3% males, 48.1% non-U.S. born with a mean length of stay of 19 years in the U.S. (SD ± 13.71) were interviewed upon completion of SAT. Results from the SEM indicated adequate model fit to the population under study, supporting the use of a multidimensional acculturation approach for this population. Subsequent results from the structured regression analysis suggest that multidimensional acculturation is negatively associated with days using alcohol in the past 6 months. The implications of these findings are discussed.

Evaluating racial disparity in referral source and successful completion of substance abuse treatment

Health disparity is a significant problem in the United States, and particularly for substance abuse treatment programs. A better understanding of racial differences in treatment pathways associated with successful treatment completion is needed to reduce the existing health disparities. Referral source is a strong predictor of treatment success and most research on health disparities has focused on the criminal justice referrals. However, little research has examined other types of referral sources, and the interaction with race. The current study sought to compare the effect of referral sources on national substance abuse successful treatment completion rates between Black clients (n=324,625) and White clients (n=1,060,444) by examining the interaction of race on referral source and successful treatment completion. Race significantly moderated the difference between referral source and successful treatment completion (Wald χ2=1477.73, df=6, p<0.0001). Employment referral was associated with the greatest percentage of successful treatment completion for Black clients. Criminal justice referral was associated with the greatest percentage of successful treatment completion for White clients. Results from the present study support a reevaluation of incentives leading to successful treatment completion with a multicultural perspective.

Differences in successful treatment completion among pregnant and non-pregnant American women.

The present study explores characteristics of successful substance abuse treatment completion of pregnant women through an analysis of retrospective outcomes data. Women without prior treatment admissions, aged 18-44, and not in methadone maintenance therapy were included (N = 678,782). Chi-square tests analyzed significant differences; logistic regression provided predictive probabilities; odds ratios (OR) and risk differences with 95 % confidence intervals represent the effect sizes and clinically meaningful differences. Pregnant women were less likely to successfully complete treatment than non-pregnant women (χ (2) = 321.33, df = 1, p < 0.0001), though the difference was not clinically meaningful (risk difference = 4.75, 95 % confidence interval (CI) = 4.23-5.26). Aside from criminal justice agencies, "other community agencies" refer the greatest percentage of pregnant women to treatment (risk difference = 6.37, 95 % CI = 5.89-6.84). Pregnant women successfully complete treatment more than non-pregnant women in only non-intensive outpatient settings (χ (2) = 10,182.48, df = 7, p < 0.0001). Further attention to referral source and treatment setting for pregnant women may improve successful treatment completion by targeting needs of pregnant women. Referring to non-intensive outpatient and residential hospital treatment settings may help to ameliorate prenatal substance abuse treatment contingent on the primary problem substance.

Nux vomica, the Arnica of Recovery from Addiction: An Exploratory Study of the Use of Homeopathy in the Reduction of Post–Acute Withdrawal Syndrome in Addiction Treatment

Clients coming out of traditional medical detoxification often experience post–acute withdrawal syndrome, symptoms of significant cravings for drugs, as well as mental, emotional and physical symptoms of protracted withdrawal. This article details a protocol of using Nux vomica in three American treatment settings, with data indicating a positive impact on both immediate symptoms and long-term stabilisation in treatment. Consistently in all three groups, those who chose to use homeopathy completed substance abuse treatment programs at a higher rate than those who did not. The authors conclude that the role of homeopathy for recovery from addiction merits further investigation.

Optimizing continuity-of-care opportunities to reduce health risks: shared qualitative perspectives from CJDATS 2 research

Current Texas Christian University (TCU) research focuses on reducing risk for relapse and other health-related behaviors associated with HIV, HBV, and HCV. The WaySafe curriculum was developed for prisoners in the last phase of their substance abuse treatment before transitioning back to the community, and was designed to improve decisionmaking and recognizing and planning for risky situations. A critical next step is to shift the setting from incarceration to a community setting with probationers during the high-risk transition period after release from prison or completion of residential or intensive outpatient substance abuse treatment. Literature supports the importance of prevention programs [1] as part of the continuity-of-care for offenders and probationers in addressing some service gaps (in the continuum), which are widely recognized to reduce the likelihood of successful client outcomes [2,3]. The purpose of this presentation is to provide evidence from the recently completed second phase of the Criminal Justice Drug Abuse Treatment Studies (CJDATS 2), with insight from key stakeholders that informs the relevance of continuity-of-care and the significant role that community corrections and community-based health-care agencies fulfill in transitioning probationers from incarceration to home. These qualitative results come from two protocols conducted as part of CJDATS 2: HIV Services and Treatment Implementation in Corrections (HIV-STIC) and Medication-Assisted Treatment in Community Corrections Environments (MATICCE). The organizational-level findings reflect the opinions and views of criminal justice personnel and health-care providers—agencies in partnership with TCU in HIV-STIC and MATICCE. In CJDATS 2, stakeholders participated in an implementation research initiative, utilizing a change team strategy to identify and implement improvements to service delivery. In both HIV-STIC and MATICCE, the services delivery continuum incorporated elements of prison-based services and transition to community-based services in their respective areas. Qualitative results highlight the important contributions of community correction agencies, their direct contact to probationers, and their ability to facilitate linkages to service providers. Findings are discussed, emphasizing the importance of staff commitment and interorganizational relationships in continuity-of-care from prison to community as essential components to optimizing services to probationers.

Substance abuse treatment processes and outcomes in day/outpatient health maintenance organization setting.

Previous research has determined that substance abuse treatment (SAT) is effective under managed care within residential treatment and outpatient treatment, but we have not followed patients after treatment completion. This study examined SAT in both an intensive day treatment and an outpatient treatment program in a large health maintenance organization, with mandatory 12-step participation. We conducted interviews (N = 72) at the beginning, upon completion, and 6 months after completion of treatment. Variables measured were substance use, quality of life, symptoms, functionality, and patient satisfaction as well as Drug Abuse Treatment and Assessment Resources (DATAR) score and treatment completion. Before treatment, DATAR scores were high: 7.68 on a scale of 1-9, indicating serious addictions. Patients showed significant improvement in all variables measured, upon completion of SAT, and additional improvement again 6 months later. Eighty-three percent of subjects completed treatment. Unique advantages of treatment in this setting were discussed, as well as the importance of referral and support from nurses and other healthcare professionals.
