Pathways to chemical dependency treatment for adolescents in an HMO

Predicting adolescent alcohol and other drug problems using electronic health records data

IMPORTANCE

Alcohol and other drug (AOD) use problems may cause significant burden on affected adolescents and their families, yet treatment providers often do not identify these problems early enough.

OBJECTIVE

To develop, and internally and externally validate a multivariable prediction model of adolescent AOD problems using child- and maternal-level predictors before age 12, and child-level predictors between ages 12 to 18, as recorded in the electronic health records (EHR).

DESIGN

A retrospective cohort study conducted time-to-event analyses using Cox proportional hazards models.

SETTING AND PARTICIPANTS

41,172 children born between 1997 and 2000 at four health plans (Kaiser Permanente Hawaii, KPHI; Kaiser Permanente Northern California, KPNC; Geisinger Clinic, GC; and Henry Ford Health System, HFHS) who had continuous membership since birth and linkable maternal records in the health plan.

OUTCOMES

AOD use problems between ages 12 to 18, defined as either: 1) having a contact with the AOD treatment program or 2) receiving a non-tobacco AOD diagnosis in an inpatient or outpatient encounter.

EXPOSURES

Candidate predictor variables include demographics, socioeconomic status, and clinical diagnoses of the children and the mothers.

RESULTS

Overall, 1400 (3.4%) adolescents had an AOD disorder between ages 12 to 18; the median follow-up time post-age 12 was 5.3 years. The research team developed two final prediction models: a "baseline" model of 10 child-level and 7 maternal-level predictors before age 12, and a more comprehensive "time-varying" model, which incorporated child risk factors after age 12 as time-varying covariates in addition to the baseline model predictors. Model performance evaluation showed good discrimination performance of the models, with the concordance index improved for the time-varying model, especially for prediction of AOD events in late adolescence.

CONCLUSIONS AND RELEVANCE

This study identified a number of child and maternal characteristics and diagnoses routinely available in EHR data as predictive of risk for developing AOD problems in adolescence. Further, we found that risk of developing problems varies significantly by the timing and persistence of the risk factors. Findings may have potential clinical implications for prevention and identification of adolescent AOD problems, but more research is needed, especially across additional health systems.

Health Care Use Over 3 Years After Adolescent SBIRT

BACKGROUND

Most studies on adolescent screening, brief intervention, and referral to treatment (SBIRT) have examined substance use outcomes. However, it may also impact service use and comorbidity-an understudied topic. We address this gap by examining effects of SBIRT on health care use and comorbidities.

METHODS

In a randomized trial sample, we assessed 3 SBIRT care modalities: (1) pediatrician-delivered, (2) behavioral clinician-delivered, and (3) usual. Medical comorbidity and health care use were compared between a brief-intervention group with access to SBIRT for behavioral health (combined pediatrician and behavioral clinician arms) and a group without (usual care) over 1 and 3 years.

RESULTS

Among a sample of eligible adolescents (n = 1871), the SBIRT group had fewer psychiatry visits at 1 year (incidence rate ratio [iRR] = 0.76; P = .05) and 3 years (iRR = 0.65; P < .05). Total outpatient visits did not differ in year 1. The SBIRT group was less likely to have mental health diagnoses (odds ratio [OR] = 0.69; 95% confidence interval [CI] = 0.48-1.01) or chronic conditions (OR = 0.66; 95% CI = 0.45-0.98) at 1 year compared with those in usual care. At 3 years, the SBIRT group had fewer total outpatient visits (iRR = 0.85; P < .05) and was less likely to have substance use diagnoses (OR = 0.64; 95% CI = 0.45-0.91) and more likely to have substance use treatment visits (iRR = 2.04; P < .01).

CONCLUSIONS

Providing SBIRT in pediatric primary care may improve health care use and health, mental health, and substance use outcomes. We recommend further exploring the effects of SBIRT on these outcomes.

Youths Perceived Parental Influence on Substance Use Changes and Motivation to Seek Treatment

Drug and alcohol use among youth has serious consequences for the physical and mental health of youth and strains their relationships with family and friends. While the task of dealing with substance-related issues often falls on families, particularly parents, very little research has explored the importance of family as a motivator for seeking treatment. This paper reports on a qualitative study of youth seeking substance abuse treatment at a large urban psychiatric hospital. Following primarily self-determination theory, the study examines youths' descriptions of how their parents motivated them to (1) change their substance use behaviors and (2) seek treatment. The sample consisted of 31 youth ages 17 to 25 engaged in outpatient services with various substance use concerns. Youth described complex and evolving relationships with their parents along their journey to enter treatment. Implications for service delivery and important insights for engaging youth and their parents are discussed.

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.

Marijuana use and service utilization among adolescents 7 years post substance use treatment

BACKGROUND

In an environment of increasingly liberal attitudes towards marijuana use and legalization, little is known about long-term trajectories of marijuana use among clinical samples of adolescents, and how these trajectories relate to health services utilization over time.

METHODS

Latent growth curve analysis was used to identify distinct trajectories of marijuana use in a clinical sample of adolescents (N=391) over 7 years post substance use treatment in an integrated health system. We examined psychiatric problems and polysubstance use associated with the identified trajectory groups using general linear models. Nonlinear mixed-effects logistic regressions were used to examine associations between health services use and the trajectory groups.

RESULTS

We identified three marijuana use trajectory groups: (1) Abstinent (n=117); (2) Low/Stable use (n=174); and (3) Increasing use (n=100). Average externalizing and anxiety/depression scores were significantly lower over time for the Abstinent group compared to the Increasing and Low/Stable groups. The Low Stable and the Increasing group had fewer psychiatric visits over time (p<0.05) and the Low/Stable group used more substance use treatment services over time compared with the Abstinent group (p<0.001).

CONCLUSIONS

Treated adolescents showed distinct marijuana use patterns, one of which indicated a group of adolescents at risk of increased use over time. These individuals have greater psychiatric and polysubstance use over time, but may not be accessing needed services.

Substance abuse and mental health visits among adolescents presenting to US emergency departments

OBJECTIVES

The objectives of the study were to identify factors associated with adolescent emergency department (ED) visits for substance abuse, including those complicated by mental health (dual diagnosis), and to analyze their effect on ED length of stay (LOS) and disposition.

METHODS

We performed a secondary analysis of ED visits by adolescents (age, 11-24) using the National Hospital Ambulatory Medical Care Survey (1997-2010) to identify visits for mental health, substance use, and dual diagnosis. Univariate and multivariate statistics were used to analyze demographic and visit-level factors, factors associated with substance use and dual diagnosis visits, as well as the effects of substance use and mental health conditions on ED LOS and disposition.

RESULTS

Substance use and mental health accounted for 2.1% and 4.3% of all adolescent visits, respectively, with 20.9% (95% confidence interval [CI], 18.3%-23.5%) of substance abuse visits complicated by mental health. The factors significantly associated with substance use include the following: male sex, urban location, West region, ambulance arrival, night and weekend shift, anxiety disorders, mood disorders, and psychotic disorders. Additional LOS was 89.77 minutes for mental health, 71.33 minutes for substance use, and 139.97 minutes for dual diagnosis visits, as compared with visits where these conditions were not present. Both mental health and substance use were associated with admission/transfer as compared with other dispositions as follows: mental health odds ratio (OR), 5.93 (95% CI, 5.14-6.84); illicit drug use OR, 3.56 (95% CI 2.72-4.64); and dual diagnosis OR, 6.86 (95% CI, 4.67-10.09).

CONCLUSIONS

Substance abuse and dual diagnosis are common among adolescent ED visits and are strongly associated with increased use of prehospital resources, ED LOS, and need for hospitalization.

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.

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.

Screening for adolescent alcohol and drug use in pediatric health-care settings: predictors and implications for practice and policy

OBJECTIVE

This paper used data from a study of pediatric primary care provider (PCP) screening practices to examine barriers to and facilitators of adolescent alcohol and other drug (AOD) screening in pediatric primary care.

METHODS

A web-based survey (N = 437) was used to examine the influence of PCP factors (attitudes and knowledge, training, self-efficacy, comfort with alcohol and drug issues); patient characteristics (age, gender, ethnicity, comorbidities and risk factors); and organizational factors (screening barriers, staffing resources, confidentiality issues) on AOD screening practices. Self-reported and electronic medical record (EMR)-recorded screening rates were also assessed.

RESULTS

More PCPs felt unprepared to diagnose alcohol abuse (42%) and other drug abuse (56%) than depression (29%) (p < 0.001). Overall, PCPs were more likely to screen boys than girls, and male PCPs were even more likely than female PCPs to screen boys (23% versus 6%, p < 0.0001). Having more time and having other staff screen and review results were identified as potential screening facilitators. Self-reported screening rates were significantly higher than actual (EMR-recorded) rates for all substances. Feeling prepared to diagnose AOD problems predicted higher self-reported screening rates (OR = 1.02, p < 0.001), and identifying time constraints as a barrier to screening predicted lower self-reported screening rates (OR = 0.91, p < 0.001). Higher average panel age was a significant predictor of increased EMR-recorded screening rates (OR = 1.11, p < 0.001).

CONCLUSIONS

Organizational factors, lack of training, and discomfort with AOD screening may impact adolescent substance-abuse screening and intervention, but organizational approaches (e.g., EMR tools and workflow) may matter more than PCP or patient factors in determining screening.

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.

Peer influences on adolescent alcohol and other drug use outcomes

PURPOSE

To examine the role of family environment and peer networks in abstinence outcomes for adolescents 1 year after intake to alcohol and other drug (AOD) treatment.

DESIGN

Survey of 419 adolescents 13 to 18 years of age at consecutive intakes to AOD treatment programs at four sites of a large health system, with telephone follow-up survey 1 year after intake.

METHODS

Examined association of 1-year abstinence with baseline characteristics. Using logistic regression, we examined characteristics predicting 1-year abstinence and predicting having fewer than four substance-using friends at 1 year.

RESULTS

We found that family environment scores related to family conflict, limit setting, and positive family experiences, were not related to abstinence outcomes, but peer networks were related. Adolescents with fewer (less than four) AOD-using friends were more likely to be abstinent than those with four or more AOD-using friends (65% vs. 41%, p= .0002). Having fewer than four AOD-using friends at intake predicted abstinence at 1 year (odds ratio [OR]= 2.904, p= .0002) and also predicted having fewer than four AOD-using friends at 1 year (OR= 2.557, p= 0.0007).

CONCLUSIONS

Although family environment is an important factor in the development of AOD problems in adolescents, it did not play a significant role in treatment success. The quality of adolescent peer networks did independently predict positive outcomes.

CLINICAL RELEVANCE

For physicians, advanced practice registered nurses, and other primary and behavioral care providers who screen and care for adolescents with AOD and other behavioral problems, our finding suggest the importance of focusing on improving the quality of their peer networks.

Access to treatment for adolescents with substance use and co-occurring disorders: challenges and opportunities

OBJECTIVE

To review the research on economic and systemic barriers faced by adolescents needing treatment for alcohol and drug problems, particularly those with co-occurring conditions.

METHOD

We reviewed the literature on adolescent access to alcohol and drug services, including early intervention, and integrated and specialty mental health treatment for those with co-occurring disorders, examining the role of health care systems, public policy (health reform), treatment financing and reimbursement systems (public and private), implementation of evidence-based practices, confidentiality practices, and treatment costs and cost/benefits.

RESULTS

Barriers to treatment, particularly integrated treatment, are largely rooted in our organizationally fragmented health care system, which encompasses public and private, carved-out and integrated systems, and different funding mechanisms (Medicaid versus block grants versus private insurance that include "high deductible" plans and other cost controls.) In both systems, carved-out programs de-link services from other mental health and general health care. Barriers are also rooted in disciplinary differences and weak clinical linkages between psychiatry, primary care and substance use, and in confidentiality policies that inhibit communication and coordination, while protecting patient privacy.

CONCLUSION

In this era of health care reform, we have the opportunity to increase access for adolescents and develop new models of integrated services for those with co-occurring conditions. We discuss opportunities for improving treatment access and implementation of evidence-based practices, examine implications of health reform and parity legislation for psychiatric and substance use treatment, and comment on key unanswered questions and future research opportunities.

Three-year chemical dependency and mental health treatment outcomes among adolescents: the role of continuing care

BACKGROUND

Few studies have examined the effects of treatment factors, including the types of services [chemical dependency (CD), psychiatric, or both], on long-term outcomes among adolescents following CD treatment, and whether receiving continuing care may contribute to better outcomes. This study examines the effect of the index CD and ongoing CD and psychiatric treatment episodes, 12-step participation, and individual characteristics such as CD and mental health (MH) severity and gender, age, and ethnicity, on 3-year CD and MH outcomes.

METHODS

Participants were 296 adolescents aged 13 to 18 seeking treatment at 4 CD programs of a nonprofit, managed care, integrated health system. We surveyed participants at intake, 1 year, and 3 years, and examined survey and administrative data, and CD and psychiatric utilization.

RESULTS

At 3 years, 29.7% of the sample reported total abstinence from both alcohol and drugs (excluding tobacco). Compared with girls, boys had only half the odds of being abstinent (OR = 0.46, p = 0.0204). Gender also predicted Externalizing severity at 3 years (coefficients 18.42 vs. 14.77, p < 0.01). CD treatment readmission in the second and third follow-up years was related to abstinence at 3 years (OR = 0.24, p = 0.0066 and OR = 3.33, p = 0.0207, respectively). Abstinence at 1 year predicted abstinence at 3 years (OR = 4.11, p < 0.0001). Those who were abstinent at 1 year also had better MH outcomes (both lower Internalizing and Externalizing scores) than those who were not (11.75 vs. 15.55, p = 0.0012 and 15.13 vs. 18.06, p = 0.0179, respectively).

CONCLUSIONS

A CD treatment episode resulting in good 1-year CD outcomes may contribute significantly to both CD and MH outcomes 3 years later. The findings also point to the value of providing a continuing care model of treatment for adolescents.

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.

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.

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.

Adolescents with co-occurring substance use and mental conditions in a private managed care health plan: prevalence, patient characteristics, and treatment initiation and engagement

This study examined the prevalence, patient characteristics, and treatment initiation and engagement of adolescents with co-occurring substance use (SU) and serious mental health (MH) diagnoses in a private, managed care health plan. We identified 2,005 adolescents aged 12-17, who received both SU and MH diagnoses within a 1-year window between 1/1/2000 and 12/31/2002; 57% were girls. Gender variations were found in diagnoses received and point of identification. Being dually diagnosed in specialty departments (rather than Primary Care and Emergency) and receiving both diagnoses within a shorter time period were associated with treatment initiation and engagement.

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.

Medical conditions of adolescents in alcohol and drug treatment: comparison with matched controls

PURPOSE

Alcohol and drug problems are associated with medical problems among adults. Research on the relationship of adolescent alcohol and drug use disorders to specific medical problems is less developed and focused on acute consequences. This study addresses gaps in the literature regarding medical comorbidities in adolescents with alcohol and drug use disorders.

METHODS

This study compares the prevalence of medical conditions among 417 adolescent alcohol and drug treatment patients with 2082 demographically matched controls from the same managed care health plan and examines whether comparisons vary among substance-type subgroups.

RESULTS

Approximately one-fourth of the comorbid conditions examined were more common among adolescent alcohol and drug patients than among matched controls, and several were highly costly conditions (e.g., asthma, injury). We also found that pain-related diagnoses, including headache and abdominal pain, were more prevalent among alcohol and drug patients.

CONCLUSIONS

Our findings point to the importance of examining comorbid medical and chemical dependency in both adolescent primary care and specialty care. Moreover, optimal treatment of many common medical disorders may require identification, intervention, and treatment of a substance use problem.

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

PURPOSE

There has been little research on adolescents of different ethnicities in chemical dependency (CD) treatment, despite a focus on ethnic disparities in health care in recent years. In particular, little is known about ethnic differences in utilization of adolescent CD services.

METHODS

We examined treatment initiation and treatment retention in a sample of African American, Native American, Latino, Asian American, and Caucasian adolescents entering CD treatment in a private, managed care health plan (n = 419). Our conceptual framework included ethnicity as the main factor as well as measures of external pressure and internal motivation/readiness for treatment, family environment, psychiatric co-morbidities, and severity of alcohol and drug problems. Logistic and Poisson regression were used to examine differences.

RESULTS

The study found ethnic differences in treatment initiation and treatment retention. Native American adolescents had lower odds of returning after intake to initiate treatment compared with Caucasians (odds ratio [OR] .35, p = .009), and African American youth spent less time in treatment than Caucasians (RR: .49, p < .001).

CONCLUSIONS

Study findings indicate differences in treatment initiation for Native Americans and in treatment retention for African Americans. Intake and orientation sessions offer an opportunity to intervene with Native American youth. Given their high psychiatric co-morbidity, they may also benefit from the availability of psychiatric services. Even after adjusting for severity, we found shorter treatment retention for African American adolescents and suggest that organizational factors, such as cultural competency, may play an important role.

Chemical dependency and psychiatric services for adolescents in private managed care: implications for outcomes

BACKGROUND

Many adolescents with alcohol and drug problems have mental health comorbidities. The literature suggests that patients entering chemical dependency (CD) treatment with co-occurring problems have less successful outcomes, including treatment dropout and relapse. We examined the impact of psychiatric services on treatment initiation, retention, and alcohol and drug abstinence outcomes for adolescents in CD treatment.

METHODS

Participants were 419 adolescents aged 12-18 years who were seeking treatment at four CD programs of a nonprofit, managed care, group model health system and a parent or guardian for each adolescent. We surveyed participants at intake and 6 months and examined clinical and administrative data on diagnoses and CD and psychiatric utilization. Six-month response rates were 91% for adolescents and 93% for parents.

RESULTS

Fifty-five percent of the patients with treatment intakes had at least one psychiatric diagnosis in addition to a substance use disorder. Compared with matched controls, patients with CD intakes had higher rates of depression, anxiety, eating disorders, attention deficit hyperactivity disorder, conduct disorder, and conduct disorder including oppositional defiant disorder. Thirty-one percent of the full sample had psychiatric visits in the 6 months after intake; among those with a psychiatric diagnosis, 54% had a psychiatric visit. Girls and those with higher Youth Self-Report internalizing scores were more likely to have a psychiatric visit (OR = 2.27, p < 0.001 and OR = 1.05, p < 0.0001, respectively). Adolescents receiving psychiatric services were more likely to be abstinent from both alcohol and drugs than those not receiving these services (OR = 1.57, 95% CI = 0.98-2.5) and more likely to be alcohol abstinent (OR = 1.68, 95% CI = 1.00-2.85). Those adolescents at colocated clinics had higher odds of abstinence from both alcohol and drugs (OR = 1.57, 95% CI = 1.03-2.39) and drugs (OR = 1.84, 95% CI = 1.87-2.85) and of returning after intake to initiate CD treatment (OR = 2.28, 95% CI = 1.44-3.61, p < 0.001) than others.

CONCLUSIONS

Our results demonstrate the need for psychiatric treatment of adolescents in CD treatment and highlight the importance of their receiving such services.
