Adolescents entering chemical dependency treatment in private managed care: ethnic differences in treatment initiation and retention

Overall and Telehealth Addiction Treatment Utilization by Age, Race, Ethnicity, and Socioeconomic Status in California After COVID-19 Policy Changes

Importance

Addiction treatment rapidly transitioned to a primarily telehealth modality (telephone and video) during the COVID-19 pandemic, raising concerns about disparities in utilization.

Objective

To examine whether there were differences in overall and telehealth addiction treatment utilization after telehealth policy changes during the COVID-19 pandemic by age, race, ethnicity, and socioeconomic status.

Design, Setting, and Participants

This cohort study examined electronic health record and claims data from Kaiser Permanente Northern California for adults (age ≥18 years) with drug use problems before the COVID-19 pandemic (from March 1, 2019, to December 31, 2019) and during the early phase of the COVID-19 pandemic (March 1, 2020, to December 31, 2020; hereafter referred to as COVID-19 onset). Analyses were conducted between March 2021 and March 2023.

Exposure

The expansion of telehealth services during COVID-19 onset.

Main Outcomes and Measures

Generalized estimating equation models were fit to compare addiction treatment utilization during COVID-19 onset with that before the COVID-19 pandemic. Utilization measures included the Healthcare Effectiveness Data and Information Set of treatment initiation and engagement (including inpatient, outpatient, and telehealth encounters or receipt of medication for opioid use disorder [OUD]), 12-week retention (days in treatment), and OUD pharmacotherapy retention. Telehealth treatment initiation and engagement were also examined. Differences in changes in utilization by age group, race, ethnicity, and socioeconomic status (SES) were examined.

Results

Among the 19 648 participants in the pre-COVID-19 cohort (58.5% male; mean [SD] age, 41.0 [17.5] years), 1.6% were American Indian or Alaska Native; 7.5%, Asian or Pacific Islander; 14.3%, Black; 20.8%, Latino or Hispanic; 53.4%, White; and 2.5%, unknown race. Among the 16 959 participants in the COVID-19 onset cohort (56.5% male; mean [SD] age, 38.9 [16.3] years), 1.6% were American Indian or Alaska Native; 7.4%, Asian or Pacific Islander; 14.6%, Black; 22.2%, Latino or Hispanic; 51.0%, White; and 3.2%, unknown race. Odds of overall treatment initiation increased from before the COVID-19 pandemic to COVID-19 onset for all age, race, ethnicity, and SES subgroups except for patients aged 50 years or older; patients aged 18 to 34 years had the greatest increases (adjusted odds ratio [aOR], 1.31; 95% CI, 1.22-1.40). Odds of telehealth treatment initiation increased for all patient subgroups without variation by race, ethnicity, or SES, although increases were greater for patients aged 18 to 34 years (aOR, 7.17; 95% CI, 6.24-8.24). Odds of overall treatment engagement increased (aOR, 1.13; 95% CI, 1.03-1.24) without variation by patient subgroups. Retention increased by 1.4 days (95% CI, 0.6-2.2 days), and OUD pharmacotherapy retention did not change (adjusted mean difference, -5.2 days; 95% CI, -12.7 to 2.4 days).

Conclusions

In this cohort study of insured adults with drug use problems, there were increases in overall and telehealth addiction treatment utilization after telehealth policies changed during the COVID-19 pandemic. There was no evidence that disparities were exacerbated, and younger adults may have particularly benefited from the transition to telehealth.

Unpacking the Layers: Dismantling Inequities in Substance Use Services and Outcomes for Racially Minoritized Adolescents

Minoritized youth have lower prevalence rates of substance use disorders (SUD) compared with White peers, but proportionally those that are diagnosed are less likely to engage in specialized care and there are few culturally responsive treatments or programs available. We examine social determinants of SUD, with emphasis on the impact of trauma, including racial trauma, and include an intersectional approach incorporating race, ethnicity, and gender. This review of the literature highlights evidence-based effective clinical practice as examples for the field in developing therapeutic approaches to SUD for this population.

Racial and Ethnic Disparities, Referral Source and Attrition From Outpatient Substance Use Disorder Treatment Among Adolescents in the United States

The following study examined the association between race, ethnicity, referral source, and reasons for attrition from substance use treatment in a sample of 72,643 discharges of adolescent youth in the United States from 2014 to 2016. Black and Hispanic adolescents were more likely to be discharged due to incarceration and termination by the facility compared to White adolescents. Adolescents referred by probation, diversion, other juvenile justice organizations, health care providers, community agencies, and individual referrals were significantly more likely to be discharged due to incarceration and terminated by the treatment facility compared to youth who were referred by schools. Findings suggest that enhancing linkage to treatment from systems in the social environment may play a role in attenuating racial and ethnic disparities in rates of attrition from substance abuse treatment among adolescent youth in the United States.

Barriers, facilitators, and disparities in retention for adolescents in treatment for substance use disorders: a qualitative study with treatment providers

BACKGROUND

Retention in substance use treatment is one of the strongest predictors of improved outcomes among adolescents, making retention an important goal of treatment. We examined treatment providers' perspectives on barriers and facilitators to treatment retention among adolescents, and their views on contributors to racial/ethnic disparities in retention including ways to address disparities.

METHODS

Semi-structured interviews were conducted with 19 providers at state-licensed detoxification, residential, and outpatient facilities serving adolescents for substance use disorders in Massachusetts. Interviews were coded by at least two independent coders.

RESULTS

Providers identified barriers and facilitators at the policy/systems, facility, family, and client levels. Some of the barriers included insurance limits on sessions/length of stay and low reimbursement (policy/systems), staff turnover (facility), low family engagement (family), and low internal motivation (client). Some facilitators mentioned were support from state's substance use agency (policy/systems), flexibility with meeting location (facility), family participation (family), and high internal motivation and presence of external motivators (client). Barriers that contributed to racial/ethnic disparities included lower socio-economic status, language barriers, and mistrust. Having bilingual/bicultural staff and multi-lingual materials, and facilitating transportation were identified as strategies for reducing disparities in treatment retention.

CONCLUSIONS

It is critical that adolescents who access substance use services remain and complete treatment and that there is equity in treatment retention. Provider perspectives in factors associated with retention can inform the development of comprehensive interventions and policies to help improve retention and reduce disparities.

Incarceration as a Reason for US Alcohol and Drug Treatment Non-completion: a Multilevel Analysis of Racial/Ethnic and Sex Disparities

Incarceration may be an overlooked reason for treatment non-completion experienced disproportionately by African Americans. This study utilized multilevel logistic regression to model treatment non-completion due to incarceration using the 2015-2016 Treatment Episode Dataset-Discharges. Among a sample restricted to treatment non-completers (n = 306,008), 5% terminated treatment because they became incarcerated (n = 13,082), which varied widely by demographics and by state. In Idaho, 46% of African Americans terminated treatment because they became incarcerated. Women had lower odds of treatment non-completion than men, and the effect of sex was strongest among African Americans (adjusted odds ratio [aOR] = 0.30, 95% confidence interval [95% CI] = 0.26-0.34). Among men, all racial/ethnic minority groups demonstrated significantly higher odds of treatment non-completion due to incarceration compared with Whites, and the strongest effect was among African Americans (aOR = 1.37, 95% CI = 1.29-1.44). Incarceration as a reason for treatment non-completion disproportionately affects African Americans and men and varies by state. Interventions targeting incarceration alternatives should be availed to racial/ethnic minorities already participating in treatment.

Levels and predictors of participation in integrated treatment programs for pregnant and parenting women with problematic substance use

Background

Women who are seeking services for problematic substance use are often also balancing responsibilities of motherhood. Integrated treatment programs were developed to address the diverse needs of women, by offering a holistic and comprehensive mix of services that are trauma- and violence-informed, and focus on maternal and child health promotion and the development of healthy relationships.

Methods

Using system-level administrative data from a suite of outpatient integrated programs in Ontario, Canada, we described the clients and rates and predictors of treatment participation over a 7-year period (2008–2014; N = 5162).

Results

All participants were either pregnant or parenting children under 6 years old at admission to treatment. Retention (length of time between the first and last visit) averaged 124.9 days (SD = 185.6), with episodes consisting of 14.6 visits (SD = 28.6). The vast majority of women attended more than one visit (87.2%), typically returning within 2 weeks (mean 12.3 days, SD = 11.1). In addition to being pregnant or new mothers experiencing problematic substance use, most were unemployed, on social assistance, and single.

Conclusions

Programs appeared to be able to successfully engage most women in treatment once they accessed the programs. Although rates of treatment participation did vary across subgroups defined by sociodemographic and admission characteristics, effect sizes tended to be small on average, providing little evidence in general of sociodemographic inequities in participation. Further work is needed to study the influence of program-level factors on participation, and how these link to maternal and child outcomes.

A system-level study of initiation, engagement, and equity in outpatient substance use treatment

Understanding the nature of variations in the quality of substance use treatment is critical to ensuring equity in service delivery and maximizing treatment effectiveness. We used adapted versions of the US Healthcare Effectiveness Data and Information Set (HEDIS) treatment initiation and engagement measures to assess care quality in specialized outpatient services for substance use in Ontario, Canada. Using administrative data, we calculated rates of outpatient treatment initiation and engagement (N = 120,394 episodes) and investigated variation by client characteristics and treatment mandates. About half of clients who entered outpatient treatment met the criteria for initiation (i.e., had a second visit within 14 days) and 30% met the criteria for engagement (i.e., had another two visits within 30 days of initiation). The likelihood of treatment initiation and engagement was greater among older people, those with more education, those who were not mandated to enter treatment, and those with greater substance use at admission. People who entered treatment for cannabis were less likely to engage. Engagement was less likely among men than women, but gender differences were slight overall. This study demonstrates the feasibility of using adapted versions of two common measures to characterise care quality in substance use treatment services in the Canadian context. Overall, the magnitude of associations with client characteristics were quite small, suggesting that initiation and engagement were not overly localized to specific client subgroups. Findings suggest that the Ontario system has difficulty retaining clients who enter treatment and that most outpatient treatment involves care episodes of limited duration.

Specialty addiction and psychiatry treatment initiation and engagement: Results from an SBIRT randomized trial in pediatrics

OBJECTIVE

Many adolescents needing specialty addiction or psychiatry treatment never access care. We examined initiation and engagement with addiction and/or psychiatry treatment among adolescents referred to treatment from a trial comparing two different modalities of delivering Screening, Brief Intervention and Referral to Treatment (SBIRT) to Usual Care in pediatric primary care. We hypothesized that both intervention arms would have higher initiation and engagement rates than usual care.

METHODS

We randomized all pediatricians (n=52) in a pediatric primary care clinic to three arms: 1) pediatrician-only arm, in which pediatricians were trained to deliver SBIRT for substance use and/or mental health problems; 2) embedded-behavioral health clinician (embedded-BHC arm), in which pediatricians referred adolescents who endorsed substance use and/or mental health problems to a BHC; and 3) Usual Care (UC). We used electronic health record (EHR) data to examine specialty addiction and psychiatry treatment initiation and engagement rates after referral.

RESULTS

Among patients who screened positive for substance use and/or mental health problems and were referred to specialty addiction and/or psychiatry (n=333), those in the embedded-BHC arm had almost four times higher odds of initiating treatment than those in the pediatrician-only arm, OR=3.99, 95% CI=[1.99-8.00]. Compared to UC, those in the pediatrician-only arm had lower odds of treatment initiation (OR=0.53, 95% CI=[0.28-0.99]), while patients in the embedded-BHC arm had marginally higher odds (OR=1.83, 95% CI=[0.99-3.38]). Black patients and those with other/unknown race/ethnicity had lower odds of treatment initiation compared with white adolescents; there were no gender or age differences. We found no differences in treatment engagement across the three arms.

CONCLUSIONS

Embedded BHCs can have a significant positive impact on facilitating treatment initiation for pediatric primary care adolescents referred to addiction and/or psychiatry services.

Socioeconomic differences in adolescent substance abuse treatment participation and long-term outcomes

Socioeconomic status (SES) has been consistently linked to poorer access, utilization and outcomes of health care services, but this relationship has been understudied in adolescent substance abuse treatment research. This study examined SES differences in adolescent's treatment participation and long-term outcomes of abstinence and 12-step attendance over five years after treatment. Data are from 358 adolescents (ages 13-18) who were recruited at intake to substance abuse treatment between 2000 and 2002 at four Kaiser Permanente Northern California outpatient treatment programs. Follow-up interviews of adolescents and their parents were conducted at 1, 3, and 5years, with over 80% response rates across time points. Using parent SES as a proxy for adolescent SES, no socioeconomic differences were found in treatment initiation, treatment retention, or long-term abstinence from alcohol or drugs. Parent education, but not parent income, was significantly associated with 12-step attendance post-treatment such that adolescents with higher parent education were more likely to attend than those with lower parent education. Findings suggest a lack of socioeconomic disparities in substance abuse treatment participation in adolescence, but potential disparities in post-treatment 12-step attendance during the transition from adolescence to young adulthood.

Initial abstinence status and contingency management treatment outcomes: does race matter?

OBJECTIVE

Limited research has evaluated African American substance users' response to evidence-based treatments. This study examined the efficacy of contingency management (CM) in African American and White cocaine users.

METHOD

A secondary analysis evaluated effects of race, treatment condition, and baseline cocaine urine sample results on treatment outcomes of African American (n = 444) and White (n = 403) cocaine abusers participating in one of six randomized clinical trials comparing CM to standard care.

RESULTS

African American and White patients who initiated treatment with a cocaine-negative urine sample remained in treatment for similar durations and submitted a comparable proportion of negative samples during treatment regardless of treatment type; CM was efficacious in both races in terms of engendering longer durations of abstinence in patients who began treatment abstinent. Whites who began treatment with a cocaine positive sample remained in treatment longer and submitted a higher proportion of negative samples when assigned to CM than standard care. African Americans who initiated treatment with a cocaine positive sample, however, did not remain in treatment longer with CM compared with standard care, and gains in terms of drug use outcomes were muted in nature relative to Whites. This interaction effect persisted through the 9-month follow-up period.

CONCLUSIONS

CM is not equally effective in reducing drug use among all subgroups, specifically African American patients who are using cocaine upon treatment entry. Future research on improving treatment outcomes in this population is needed.

Association of race and age with treatment attendance and completion among adult marijuana users in community-based substance abuse treatment

OBJECTIVES

African American youth who use marijuana are less likely to attend and complete treatment than white youth. Limited information is available on racial and age variation in treatment attendance and completion among adults who use marijuana.

METHODS

The current research examined differences in community-based substance abuse treatment attendance and completion between adult African American and white marijuana users in 2 independent samples from the US southeastern (N = 160; 70.6% African American) and mid-Atlantic (N = 450; 34.7% African American) regions.

OUTCOMES

Attended at least 3 treatment sessions, successful treatment completion, number of days in treatment, and percentage of positive urine drug screens. Adjusted regression models examined the association of race, age, and the interaction of race and age with treatment attendance and completion.

RESULTS

In the southeastern sample, successful treatment completion was significantly associated with the interaction of race and age (adjusted odds ratio = 1.35, 95% confidence interval = 1.08-1.69); whereas younger African Americans were less likely to complete treatment than older African Americans, age was unrelated to treatment completion among whites. In the mid-Atlantic sample, African Americans were significantly less likely to attend at least 3 treatment sessions (adjusted odds ratio = 0.37, 95% confidence interval = 0.23-0.58), and younger adult marijuana users were retained for fewer days in treatment (adjusted β = 0.13, 95% confidence interval = 0.27-2.48). Among African Americans, 37.9% (SD = 38.0) of urine drug screens tested positive for at least 1 illicit drug, and among whites, 34.2% (SD = 37.8%) tested positive; the percentage of positive urine drug screens was not associated with race or age.

CONCLUSIONS

Among marijuana-using adults, treatment attendance and completion differ by race and age, and improvements in treatment completion may occur as some African Americans mature out of young adulthood.

Explaining racial/ethnic differences in adolescent substance abuse treatment completion in the United States: a decomposition analysis

PURPOSE

To identify contributors to racial/ethnic differences in completion of alcohol and marijuana treatment among adolescents at publicly funded providers.

METHODS

The 2007 Treatment Episode Data Set provided substance use history, treatment setting, and treatment outcomes for youth aged 12-17 years from five racial/ethnic groups (N = 67,060). Individual-level records were linked to variables measuring the social context and service system characteristics of the metropolitan area. We implemented nonlinear regression decomposition to identify variables that explained minority-white differences.

RESULTS

Black and Hispanic youth were significantly less likely than whites to complete treatment for both alcohol and marijuana. Completion rates were similar for whites, Native Americans, and Asian-Americans, however. Differences in predictor variables explained 12.7% of the black-white alcohol treatment gap and 7.6% of the marijuana treatment gap. In contrast, predictors explained 57.4% of the Hispanic-white alcohol treatment gap and 19.8% of the marijuana treatment gap. While differences in the distribution of individual-level variables explained little of the completion gaps, metropolitan-level variables substantially contributed to Hispanic-white gaps. For example, racial/ethnic composition of the metropolitan area explained 41.0% of the Hispanic-white alcohol completion gap and 23.2% of the marijuana completion gap. Regional differences in addiction treatment financing (particularly use of Medicaid funding) explained 13.7% of the Hispanic-white alcohol completion gap and 9.8% of the Hispanic-white marijuana treatment completion gap.

CONCLUSIONS

Factors related to social context are likely to be important contributors to white-minority differences in addiction treatment completion, particularly for Hispanic youth. Increased Medicaid funding, coupled with culturally tailored services, could be particularly beneficial.

Drug refusal skills training does not enhance outcomes of African American adolescents with substance use problems

In prior research by Witkiewitz and colleagues, African American adults receiving refusal skills training (RST) had fewer heavy drinking days and were categorized as having more successful outcomes. This study extends findings to adolescents receiving the Adolescent Community Reinforcement Approach (A-CRA). Propensity score matching was used to create three groups equivalent on baseline characteristics, including: African Americans receiving refusal skills training (AA+RST; n=214), African Americans not receiving RST (AA-RST; n=212), and Caucasians receiving RST (CA+RST; n=214). In propensity weighted regression models that controlled for overall A-CRA exposure, racial group by RST status was not a significant predictor of substance use frequency or abstinence/early remission outcomes. Higher exposure to A-CRA, however, was a significant predictor of both outcomes. Universal receipt of RST may not improve the outcomes of African American adolescents with substance use problems, and outcomes may be driven more by the overall number of A-CRA procedures received.

Does cultural adaptation have a role in substance abuse treatment?

The changing ethnic composition of the nation and increasing requirements to use evidence-based treatments (EBTs) challenge mental health professionals to adapt treatments and interventions to be appropriate for their clients. This article applies the available information on cultural adaptation to substance abuse. The authors' review suggests that the most common approaches for adapting substance use interventions include some combination of either community involvement in the adaptation, existing research and literature, and/or consultation from experts to adapt EBTs. The challenges facing the development of culturally adapted interventions include the need for additional research to determine which specific EBTs warrant adaptation, the responsibility of maintaining the balance between fidelity and adaptation, and the challenge of intragroup diversity.

12-step participation and outcomes over 7 years among adolescent substance use patients with and without psychiatric comorbidity

This study examines the associations between 12-step participation and outcomes over 7 years among 419 adolescent substance use patients with and without psychiatric comorbidities. Although level of participation decreased over time for both groups, comorbid adolescents participated in 12-step groups at comparable or higher levels across time points. Results from mixed-effects logistic regression models indicated that for both groups, 12-step participation was associated with both alcohol and drug abstinence at follow-ups, increasing the likelihood of either by at least 3 times. Findings highlight the potential benefits of 12-step participation in maintaining long-term recovery for adolescents with and without psychiatric disorders.

Moderating effects of race in clinical trial participation and outcomes among marijuana-dependent young adults

BACKGROUND

Few studies have examined clinical trial participation rates and treatment outcomes among underserved young adults who are dependent on marijuana, the most commonly abused illicit drug.

METHOD

The present study was a secondary analysis of a trial of court-referred marijuana-dependent young adults (ages 18-25) randomized to one of four treatment conditions: Motivational Enhancement Therapy/Cognitive Behavioral Therapy (MET/CBT), MET/CBT+Contingency Management (CM), Drug Counseling (DC) or DC+CM. African American (N=81) participants were compared to White (N=31) participants with respect to rates of participation in phases of treatment and substance use outcomes. In addition, the interaction of race and treatment condition was examined to ascertain if the interventions yielded different effects based on race.

RESULTS

Among those who started treatment, African American young adults were significantly less likely to complete the treatment and posttreatment phases of the clinical trial than their White counterparts. Irrespective of treatment type, substance use outcomes (i.e., percentage of marijuana-negative specimens and longest duration of continuous abstinence) did not vary by race. However, there was a significant interaction effect between treatment type and race; African American young adults did not benefit differentially from any specific type of treatment, but CM was effective in reducing proportion of marijuana positive samples among White young adults.

CONCLUSIONS

Findings suggest that clinical trial treatment and posttreatment completion rates vary by race in this population, as does response to specific treatment types. More treatment research focusing specifically on African American marijuana-dependent young adults is warranted.

12-Step participation reduces medical use costs among adolescents with a history of alcohol and other drug treatment

BACKGROUND

Adolescents who attend 12-step groups following alcohol and other drug (AOD) treatment are more likely to remain abstinent and to avoid relapse post-treatment. We examined whether 12-step attendance is also associated with a corresponding reduction in health care use and costs.

METHODS

We used difference-in-difference analysis to compare changes in seven-year follow-up health care use and costs by changes in 12-step participation. Four Kaiser Permanente Northern California AOD treatment programs enrolled 403 adolescents, 13-18-years old, into a longitudinal cohort study upon AOD treatment entry. Participants self-reported 12-step meeting attendance at six-month, one-year, three-year, and five-year follow-up. Outcomes included counts of hospital inpatient days, emergency room (ER) visits, primary care visits, psychiatric visits, AOD treatment costs and total medical care costs.

RESULTS

Each additional 12-step meeting attended was associated with an incremental medical cost reduction of 4.7% during seven-year follow-up. The medical cost offset was largely due to reductions in hospital inpatient days, psychiatric visits, and AOD treatment costs. We estimate total medical use cost savings at $145 per year (in 2010 U.S. dollars) per additional 12-step meeting attended.

CONCLUSIONS

The findings suggest that 12-step participation conveys medical cost offsets for youth who undergo AOD treatment. Reduced costs may be related to improved AOD outcomes due to 12-step participation, improved general health due to changes in social network following 12-step participation, or better compliance to both AOD treatment and 12-step meetings.

Integrating substance use treatment into adolescent health care

Substance use (SU) problems are common among adolescents, a serious health risk for them and a major public health problem, but are inadequately addressed in most pediatric health care settings. Primary care offers an excellent context for SU assessment and treatment for adolescents and their families, offering better access and a less stigmatized environment for receiving treatment than specialty programs. This paper examines the literature on the integration of substance use treatment with adolescent health care, focusing on 2 areas: Screening, Brief Intervention, and Referral to Treatment (SBIRT) in Emergency Departments and Primary Care, and School- and College-Based Health Centers.

Adolescent treatment initiation and engagement in an evidence-based practice initiative

This study examined client and program factors predicting initiation and engagement for 2,191 adolescents at 28 outpatient substance abuse treatment sites implementing evidence-based treatments. Using Washington Circle criteria for treatment initiation and engagement, 76% of the sample initiated, with 59% engaging in treatment. Analyses used a 2-stage Heckman probit regression, accounting for within-site clustering, to identify factors predictive of initiation and engagement. Adolescents treated in a pay-for-performance (P4P) group were more likely to initiate, whereas adolescents in the race/ethnicity category labeled other (Native American, Asian, Pacific Islander, Native Alaskan, Native Hawaiian, mixed race/ethnicity), or who reported high truancy, were less likely to initiate. Race/ethnicity groups other than Latinos were equally likely to engage. Among White adolescents, each additional day from first treatment to next treatment reduced likelihood of engagement. Although relatively high initiation and engagement rates were achieved, the results suggest that attention to program and client factors may further improve compliance with these performance indicators.

Look to the relationship: a review of African American women substance users' poor treatment retention and working alliance development

Emergent findings specific to African American women confirm that their substance user treatment retention rates are significantly lower than other groups, which is problematic given that substance user treatment is effective largely to the extent that clients are retained in treatment. This article reviews existing literature concerning disparities in treatment retention, highlights a significant barrier to treatment retention for this population, and presents support for an empirical focus on culturally responsive working alliance development as a promising step toward improving retention rates for African American women substance users.

Twelve-Step attendance trajectories over 7 years among adolescents entering substance use treatment in an integrated health plan

AIMS

This study examines 12-Step attendance trajectories over 7 years, factors associated with the trajectories, and relationships between the trajectories and long-term substance use outcomes among adolescents entering out-patient substance use treatment in a private, non-profit integrated managed-care health plan.

DESIGN

Longitudinal observational study.

SETTING

Four Kaiser Permanente Northern California substance use treatment programs.

PARTICIPANTS

A total of 391 adolescents entering treatment between 2000 and 2002 who completed at least one follow-up interview in year 1, and at least one during years 3-7, after treatment entry.

MEASUREMENTS

Alcohol and drug use, 12-Step meeting attendance and activity involvement and post-treatment medical service utilization.

FINDINGS

Semiparametric group-based modeling identified three distinct 12-Step attendance trajectory groups over 7 years: low/no attendance (60%), early but not continued (26%) and continued (14%). There were lower proportions of males and of adolescents with prior substance use treatment experience in the low/no attendance group (P = 0.019 and P = 0.003, respectively). In addition, those in the low/no attendance group had lower perception on circumstances, motivation and readiness for treatment at baseline (P = 0.023). Multivariate logistic generalized estimating equation analyses found that those in the continued group were more likely to be abstinent from both alcohol and drugs during follow-ups than those in the low/no attendance group [odds ratio (OR) = 2.40, P = 0.003 and OR = 1.96, P = 0.026, respectively]. However, no differences in long-term outcomes were found between those in the other two groups.

CONCLUSION

Robust connection with 12-Step groups appears to be associated with better long-term outcomes among adolescents with substance use disorders.

Racial and ethnic differences in substance abuse treatment initiation and engagement

This study examined variations by race and ethnicity in initiation and engagement, two performance measures of treatment for substance use disorders that focus on the timely receipt of services during the early stage of substance abuse treatment. Administrative data from the Oklahoma Department of Mental Health and Substance Abuse Services were linked with facility-level information from the National Survey of Substance Abuse Treatment Services. We found that Black clients were least likely to initiate treatment, but no race or ethnic differences in treatment engagement were found when compared by race or ethnicity. Most client and facility characteristics' association with initiation or engagement did not differ across racial or ethnic groups. Increased attention is needed to understand what may contribute to the differences and how to address them. This study also offers an approach that state agencies may implement for monitoring treatment quality and examining racial and ethnic disparities in substance abuse treatment services.

Conducting research with racial/ethnic minorities: methodological lessons from the NIDA Clinical Trials Network

BACKGROUND

Multiple studies in the National Institute on Drug Abuse Clinical Trials Network (CTN) demonstrate strategies for conducting effective substance abuse treatment research with racial/ethnic minorities (REMs).

OBJECTIVES

The objectives of this article are to describe lessons learned within the CTN to (1) enhance recruitment, retention, and other outcomes; (2) assess measurement equivalence; and (3) use data analytic plans that yield more information.

METHOD

This article includes background information and examples from multiple CTN studies on inclusion, measurement, and data analysis.

RESULTS AND CONCLUSIONS

Seven recommendations are included for conducting more effective research on REMs.

Racial/ethnic disparities in patterns and determinants of criminal justice involvement among youth in substance abuse treatment programs

Adolescent substance abuse is a criminal behavior; however, not all criminal behaviors result in criminal justice involvement. This study examined disparities among adolescents aged 12 to 17 admitted to substance abuse treatment nationwide. Findings indicate significant disparities in patterns and determinants of criminal justice involvement between White and minority adolescents. Minorities were significantly more likely to be involved with the criminal justice system, even after controlling for criminal behaviors, substance abuse, mental health problems, and socioenvironmental risk. Findings reveal that connections to the educational system may be especially important for minority groups. The importance of developing systems of treatment for adolescents in the community and correctional system that are part of the same continuum of care is highlighted.

Factors Associated with Motivation to Change HIV Risk and Substance Use Behaviors among Homeless Youth

This study sought to identify and compare variables associated with motivation to change alcohol, drug use, and HIV risk behaviors among a sample of homeless youths. More frequent alcohol use, older age, and childhood sexual abuse was associated with greater motivation to change alcohol use; higher reported negative consequences of substance use was associated with higher motivation to reduce illicit drug use. Shorter periods of current homelessness predicted higher motivation to change HIV risk behaviors. Findings suggest these areas might be fruitful targets of intervention efforts to enhance motivation to reduce alcohol and illicit drug use and HIV risk behaviors.

Equivalence of family functioning and externalizing behaviors in adolescent substance users of different race/ethnicity

The Brief Strategic Family Therapy for Adolescent Drug Abuse clinical trial of 480 adolescents boys and girls aged 12 to 17 years and their parents was designed to maximize the chance that a sufficient number of Hispanic and Black adolescents would be included to allow valid subgroup comparisons. Examination of measurement invariance is an important step to ensure valid analysis. Two construct areas important to the analysis of trial results, adolescent problem behaviors, and family functioning showed a high degree of measurement invariance, which allowed valid comparisons of mean baseline differences across groups. Results showed that Black families had significantly higher initial levels of family functioning and lower levels of adolescent externalizing behaviors than either Hispanic or White non-Hispanic families. This pattern is consistent with an increased likelihood of referral of Black adolescents with more severe problems to restricted setting rather than to outpatient drug abuse treatment. This possibility highlights the importance of considering differing baseline characteristics of subgroups prior to assessing differential treatment effectiveness to prevent confounding.

Ethnic disparities in accessing treatment for depression and substance use disorders in an integrated health plan

OBJECTIVE

This study examined ethnic differences in accessing treatment for depression and substance use disorders (SUDs) among men and women in a large integrated health plan, and explored factors potentially contributing to health care disparities.

METHODS

Participants were 22,543 members ages 20 to 65 who responded to health surveys in 2002 and 2005. Survey questions were linked to provider-assigned diagnoses, electronic medication, psychiatry, and chemical dependency program records.

RESULTS

Among women diagnosed with depression, Latinas (p < .01) and Asian-Americans (p < .001) were less likely than Whites to fill an antidepressant prescription. Among men diagnosed with depression, African Americans (p < .01) were less likely than Whites to do so. Among women diagnosed with an SUD, African Americans (p < .05) were less likely than Whites to have one or more chemical dependency program visits.

CONCLUSIONS

Results demonstrated ethnic differences in accessing depression and SUD treatment among patients diagnosed with these disorders, which persisted after controlling for education, income, having a regular health care provider and length of health plan enrollment. Findings highlight potential gender differences in ethnic disparities, lower antidepressant utilization among Asian Americans, and the effects of co-occurring disorders in accessing behavioral health care.

Substance use, symptom, and employment outcomes of persons with a workplace mandate for chemical dependency treatment

OBJECTIVE

This study examined the role of workplace mandates to chemical dependency treatment in treatment adherence, alcohol and drug abstinence, severity of employment problems, and severity of psychiatric problems.

METHODS

The sample included 448 employed members of a private, nonprofit U.S. managed care health plan who entered chemical dependency treatment with a workplace mandate (N=75) or without one (N=373); 405 of these individuals were followed up at one year (N=70 and N=335, respectively), and 362 participated in a five-year follow up (N=60 and N=302, respectively). Propensity scores predicting receipt of a workplace mandate were calculated. Logistic regression and ordinary least-squares regression were used to predict length of stay in chemical dependency treatment, alcohol and drug abstinence, and psychiatric and employment problem severity at one and five years.

RESULTS

Overall, participants with a workplace mandate had one- and five-year outcomes similar to those without such a mandate. Having a workplace mandate also predicted longer treatment stays and improvement in employment problems. When other factors related to outcomes were controlled for, having a workplace mandate predicted abstinence at one year, with length of stay as a mediating variable.

CONCLUSIONS

Workplace mandates can be an effective mechanism for improving work performance and other outcomes. Study participants who had a workplace mandate were more likely than those who did not have a workplace mandate to be abstinent at follow-up, and they did as well in treatment, both short and long term. Pressure from the workplace likely gets people to treatment earlier and provides incentives for treatment adherence.

Twelve-Step affiliation and 3-year substance use outcomes among adolescents: social support and religious service attendance as potential mediators

AIMS

Twelve-Step affiliation among adolescents is little understood. We examined 12-Step affiliation and its association with substance use outcomes 3 years post-treatment intake among adolescents seeking chemical dependency (CD) treatment in a private, managed-care health plan. We also examined the effects of social support and religious service attendance on the relationship.

DESIGN

We analyzed data for 357 adolescents, aged 13-18, who entered treatment at four Kaiser Permanente Northern California CD programs between March 2000 and May 2002 and completed both baseline and 3-year follow-up interviews.

MEASURES

Measures at follow-up included alcohol and drug use, 12-Step affiliation, social support and frequency of religious service attendance.

FINDINGS

At 3 years, 68 adolescents (19%) reported attending any 12-Step meetings, and 49 (14%) reported involvement in at least one of seven 12-Step activities, in the previous 6 months. Multivariate logistic regression analyses indicated that after controlling individual and treatment factors, 12-Step attendance at 1 year was marginally significant, while 12-Step attendance at 3 years was associated with both alcohol and drug abstinence at 3 years [odds ratio (OR) 2.58, P < 0.05 and OR 2.53, P < 0.05, respectively]. Similarly, 12-Step activity involvement was associated significantly with 30-day alcohol and drug abstinence. There are possible mediating effects of social support and religious service attendance on the relationship between post-treatment 12-Step affiliation and 3-year outcomes.

CONCLUSIONS

The findings suggest the importance of 12-Step affiliation in maintaining long-term recovery, and help to understand the mechanism through which it works among adolescents.

Racial and Ethnic Composition as a Correlate of Medication Availability within Addiction Treatment Organizations

Most analyses of racial and ethnic disparities in healthcare focus on individuals rather than organizations. Healthcare organizations may be one mechanism that produces disparities if the representation of minorities within organizations' patient populations is associated with differential patterns of service delivery. This research considers whether the racial and ethnic composition of addiction treatment centers' caseloads is associated with the likelihood that organizations offer any prescription medications to treat addiction, psychiatric conditions, or pain. Data were collected from 288 publicly-funded substance abuse treatment centers in the US. Logistic regression was used to estimate models of medication availability. The percentage of racial and ethnic minority patients was negatively associated with the odds of medication availability, even after controlling for organizational characteristics and patients' diagnostic characteristics. Future research should continue to investigate how healthcare organizations may produce inequalities in access to high-quality care.

Differences in service utilization and barriers among Blacks, Hispanics, and Whites with drug use disorders

Background

Treatment for drug use disorders (DUD) can be effective, but only a small proportion of people with DUD seek or receive treatment. Research on racial and ethnic treatment differences and disparities remains unclear. Understanding racial and ethnic differences and disparities in drug treatment is necessary in order to develop a more effective referral system and to improve the accessibility of treatment. The purpose of the current study was to explore the role of race and ethnicity in service utilization.

Methods

Using data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), this study examined racial and ethnic differences in use of 14 types of treatment services for DUD and 27 different treatment barriers among persons who met lifetime criteria for a DUD. Multivariate logistic regression analyses were used to examine service utilization and barriers among the racial and ethnic groups, while adjusting for other sociodemographic and clinical variables.

Results and discussion

Among Blacks, Hispanics and Whites in the overall NESARC sample, approximately 10.5% met criteria for at least one lifetime drug use disorder. Approximately 16.2% of persons with a lifetime DUD received at least one type of service. Overall, this study indicated that Whites were less likely to report receiving help for drug-related problems than Blacks, Blacks used a greater number of different types of services, and no racial and ethnic differences were observed with respect to perceived barriers to drug treatment. However, by examining types of services separately, a complex picture of racial and ethnic differences emerges. Most notably, Whites were most likely to use professional services, whereas Blacks were most likely to use 12-step and clergy. The service use pattern of Hispanics most resembled that of Whites.

Conclusion

While structural barriers to accessing treatment were observed, broad-based educational programs and interventions that are appropriately targeted to racial and ethnic groups remains an important area for prevention and treatment.

Self-initiated tobacco cessation and substance use outcomes among adolescents entering substance use treatment in a managed care organization

PURPOSE

Adolescents with substance use (SU) problems have high rates of tobacco use, yet SU treatment has historically ignored treatment for tobacco use. Barriers to such efforts include the belief that tobacco cessation could compromise other SU abstinence. This study examines self-initiated tobacco cessation and 12-month alcohol and drug abstinence in adolescents entering SU treatment in a private, managed care organization.

RESULTS

Self-initiated tobacco cessation at 6 months, and at both 6 and 12 months, were related to higher odds of drug abstinence but not alcohol abstinence.

CONCLUSION

Self-initiated tobacco cessation was not related to poor SU outcomes, and may be important to maintaining drug abstinence. Implementing tobacco cessation efforts in SU treatment can be challenging, but comprised SU outcomes may not be a barrier. The positive associations for drug abstinence and lack of associations for alcohol abstinence could be due to differences in motivation, medical conditions, or to the illicit nature of drug use. Tobacco use has serious long-term health consequences, and tobacco cessation efforts in adolescent SU treatment programs need further research.

How do resource dependencies affect treatment practices? The case of outpatient substance abuse treatment programs

This study uses resource dependence theory to examine how the concentration of client referrals into outpatient substance abuse treatment may affect treatment comprehensiveness. Data were from the 1995, 1999/2000, and 2005 waves of a national longitudinal survey. Results from generalized estimating equation models (sample sizes from 1,350 to 1,375) indicate that more concentrated referral sources were negatively associated with three of the four indicators of treatment comprehensiveness: the percentages of clients receiving routine medical care, mental health care, and financial counseling. Substance abuse treatment programs may be focusing their treatment practices to meet the demands of key referral sources. Given the importance of comprehensive treatment for substance abusing clients, however, these findings raise concerns about the potential implications of continued industry consolidation. The authors suggest strategies for organizations as well as policy makers to mitigate possible negative effects of very high reliance on one or two referral sources.

Organizational determinants of outpatient substance abuse treatment duration in women

Longer treatment duration has consistently been related to improved substance use outcomes. This study examined how tailored women's programming and organizational characteristics were related to duration in outpatient substance abuse treatment in women. Data were from two waves of a national outpatient substance abuse treatment unit survey (n = 571 in 1999/2000, n = 566 in 2005). Analyses were conducted separately for methadone and nonmethadone programs. Negative binomial regressions tested associations between organizational determinants, tailored programming, and women's treatment duration. Of the tailored programming services, childcare was significantly related to longer duration in the nonmethadone programs, but few other organizational factors were. Tailored programming was not associated to treatment duration in methadone programs, but ownership, affiliation, and accreditation were related to longer duration. Study findings suggest evidence for how external relationships related to resources, treatment constraints, and legitimacy may influence women's treatment duration. Methadone programs may be more vulnerable to external influences.

Organizational determinants of boundary spanning activity in outpatient substance abuse treatment programmes

OBJECTIVES

Substance abuse treatment programmes depend on boundary spanning to identify opportunities and threats, and represent their interests to stakeholders such as licensing entities and regulators. This study sought to identify director, client, unit and market factors associated with active director boundary spanning.

METHODS

Using data from the 1995, 1999-2000 and 2005 waves of a national survey of outpatient substance abuse treatment units, generalized estimating equation regression models tested associations between predictors and five aspects of directors' self-reported boundary spanning.

RESULTS

Directors licensed as substance abuse treatment counsellors spent more time than average consulting with other treatment providers and making presentations in the community. Older directors spent less time consulting with other treatment providers, making community presentations and liaisoning with monitoring organizations. The few associations between client unemployment and director boundary spanning were positive; the two associations between the percentage of clients who were African-American and boundary spanning were negative. Private ownership and being based in larger organizations were negatively associated with some types of boundary spanning. Perceived competition for public support was positively associated with all measures of boundary spanning.

CONCLUSION

Directors of treatment organizations may improve treatment practices and political leverage by directly, but selectively, interacting with key external stakeholders.

Substance use, education, employment, and criminal activity outcomes of adolescents in outpatient chemical dependency programs

Although the primary outcome of interest in clinical evaluations of addiction treatment programs is usually abstinence, participation in these programs can have a wide range of consequences. This study evaluated the effects of treatment initiation on substance use, school attendance, employment, and involvement in criminal activity at 12 months post-admission for 419 adolescents (aged 12 to 18) enrolled in chemical dependency recovery programs in a large managed care health plan. Instrumental variables estimation methods were used to account for unobserved selection into treatment by jointly modeling the likelihood of participation in treatment and the odds of attaining a certain outcome or level of an outcome. Treatment initiation significantly increased the likelihood of attending school, promoted abstinence, and decreased the probability of adolescent employment, but it did not significantly affect participation in criminal activity at the 12-month follow-up. These findings highlight the need to address selection in a non-experimental study and demonstrate the importance of considering multiple outcomes when assessing the effectiveness of adolescent treatment.

Tailoring of outpatient substance abuse treatment to women, 1995-2005

BACKGROUND

Tailoring substance abuse treatment to women often leads to better outcomes. Previous evidence, however, suggests limited availability of such options.

OBJECTIVES

This investigation sought to depict recent changes in outpatient substance abuse treatment (OSAT) tailoring to women and to identify unit and contextual factors associated with these practices.

RESEARCH DESIGN

Data were from 2 waves of a national OSAT unit survey (N = 618 in 1995, N = 566 in 2005). Comparisons of weighted means between waves indicate which practices changed over time. Multiple logistic regressions with generalized estimating equations test associations between unit and contextual attributes and tailoring to women.

MEASURES

Tailoring to women was measured as availability of prenatal care, child care, single sex therapy, and same sex therapists, and the percentage of staff trained to meet female clients' needs.

RESULTS

Two measures of tailoring to women declined significantly between 1995 and 2005: availability of single sex therapy (from 66% to 44% of units) and percent of staff trained to work with women (from 42% to 32% of units). No aspect of tailoring to women became more common. Proportion of female clients, total number of clients, methadone status, and private and government managed care were associated with higher odds of tailoring to women. For-profit facilities, which became more prevalent during the study period, had lower odds than other units of tailoring treatment to women.

CONCLUSIONS

Some key aspects of OSAT tailoring to women decreased significantly in the last decade. Managed care contracts may offer 1 mechanism for counteracting these trends.

Health care services use by adolescents with intakes into an outpatient alcohol and drug treatment program

We examined utilization and cost in the 1 year pre- and post-intake among a sample of adolescents (N=419) entering chemical dependency (CD) treatment. Multivariate analyses showed that these youth used significantly more medical services than a demographically matched sample of members without substance use (SU) problems. Their utilization and costs were higher than matched members, and they did not show the same reductions in post-treatment costs that adults do. This is of concern since it would appear that the medical and mental health problems of adolescents entering CD treatment may be so severe that there are no short-term reductions in post-treatment cost, including ER and hospitalizations.

Windows of opportunity: fundamental concepts for understanding alcohol-related disparities experienced by young Blacks in the United States

This paper presents a theoretical framework for conceptualizing alcohol-related disparities experienced by young Blacks in the United States. The framework highlights areas of risk and opportunity as they relate to the development of alcohol use and alcohol-related problems. In this paper, life course development theory serves as a guide for identifying a critical period in the development of alcohol-related disparities and it serves to guide the identification of opportunities to prevent or attenuate this health outcome. We also highlight concepts from ecosocial theory, resilience theory, and prevention science that advance our understanding of risk and protective factors for the social problems that young Blacks experience related to alcohol use. We conclude with suggestions for designing studies that range from etiology to preventive interventions. We also recommend methodologies that allow for more nuanced understandings of the etiology and prevention of alcohol use and alcohol-related problems experienced by young Blacks than have been available to date.

Do licensing and accreditation matter in outpatient substance abuse treatment programs?

Licensing and accreditation are widely used to improve and convey organizational quality. The objective of this study was to provide substance abuse treatment stakeholders with better evidence about how well licensing and accreditation actually correlate with staffing and treatment practices. Regressions using data from national surveys of outpatient substance abuse treatment facilities indicated that no form of licensing or accreditation was associated with better staff-to-client ratios or with one important aspect of comprehensive treatment -- the percentage of clients receiving routine medical care. There were several positive associations between licensing/accreditation and other aspects of treatment comprehensiveness. Three categories of licensure/accreditation were also positively associated with use of after-treatment plans. Post hoc analyses revealed that accreditation was associated with units' organizational contexts and referral sources as well as the nature of the competitive environment. Licensing/accreditation may reveal as much about units' institutional environments as about the quality of treatment provided.
