Is conventional wisdom wrong? Coverage for substance abuse treatment under Medicaid managed care

Conventional wisdom suggests that coverage for substance abuse treatment under Medicaid is generally poor, and that access to care may be reduced when control over behavioral health services is given to private health plans, such as those under Medicaid managed care. To examine this premise, this study reports on a cross-sectional comparative survey of state Medicaid managed care programs conducted in the year 2000. Although not all states provided substance abuse benefits under their Medicaid programs, our findings suggest that a majority of states used managed care arrangements to provide substance abuse treatment, with most providing an array of covered services. Most Medicaid behavioral health plans were fully capitated. The number of comprehensive health plans providing substance abuse services was slightly higher than the number of behavioral health carveouts. About half of the waiver programs that covered substance abuse treatment covered methadone maintenance, but waiver programs employing comprehensive health plans were more likely to provide coverage for methadone maintenance.     

Out of touch or on the money: Do the clinical objectives of addiction treatment coincide with economic evaluation results?

Previous economic studies have examined the association between substance abuse treatment and reduced costs to society, but it remains uncertain whether the economic measures used in cost and benefit-cost analyses of treatment programs correspond in direction and magnitude with clinical outcomes. In response to this uncertainty, the present study analyzed a longitudinal data set of addiction treatment clients to determine the statistical agreement between clinical and economic outcomes over time. Data were collected from 1,326 clients in the Chicago cohort of the Persistent Effects of Treatment Study. These individuals were interviewed at baseline as well as at 6-, 24-, 36-, and 48-month followup periods (91.6% followup). Correlations between clinical and economic measures were generally small (rho of 0.1 to 0.3) and often became non-significant once we controlled for baseline severity. The results demonstrate that although some associations exist, outcomes should be evaluated along both clinical and economic dimensions.     

Factors Associated with Frequent Utilization of Crisis Substance Use Detoxification Services

ABSTRACT

Previous research suggests that some substance users have multiple crisis detoxification visits and never access rehabilitation care. This care-seeking pattern leads to poorer outcomes and higher costs. The authors aimed to identify predictors of repeat detoxification visits by analyzing state-level data routinely collected at the time of substances use services admission. Repeat detoxification clients were more likely to be homeless, city-dwelling fee-for-service Medicaid recipients. Repeat detoxification clients were less likely than those with one admission to enter rehabilitation within 3 days. Treatment providers should aim for rapid transfer to rehabilitation and consider expanding detoxification intake data to improve risk stratification.     

Economic benefits of substance abuse treatment: findings from Cuyahoga County, Ohio

We estimated long-term economic benefits and treatment costs for a sample of substance abuse clients who received treatment in Cuyahoga County, Ohio, using health, criminal activity, and earnings data from the Persistent Effects of Treatment Studies. Clients were interviewed at baseline and 6, 12, 24, and 30 months following baseline. We find positive benefits from substance abuse treatment, almost of all of which were derived from reduced criminal activity and increased real earnings, with overall benefit-to-cost ratios ranging from 2.8 to 4.1. The reductions in costs to society were found to be persistent over the long-term, 30-month follow-up period. On average, treatment was found to be cost beneficial regardless of the number of times a client entered treatment in the baseline or follow-up periods. Clients who entered residential treatment and then step down to less intensive care showed greater treatment benefits than clients who only received residential treatment.

Treating depression and substance use: a randomized controlled trial

Few integrated substance use and depression treatments have been developed for delivery in outpatient substance abuse treatment settings. To meet the call for more "transportable" interventions, we conducted a pilot study to test a group cognitive-behavioral therapy (CBT) for depression and substance use that was designed for delivery by outpatient substance abuse treatment counselors. Seventy-three outpatient clients were randomized to usual care enhanced with group CBT or usual care alone and assessed at three time points (baseline and 3 and 6 months postbaseline). Our results demonstrated that the treatment was acceptable and feasible for delivery by substance abuse treatment staff despite challenges with recruiting clients. Both depressive symptoms and substance use were reduced by the intervention but were not significantly different from the control group. These results suggest that further research is warranted to enhance the effectiveness of treatment for co-occurring disorders in these settings.     

A day treatment program in a therapeutic community setting: six-month Outcomes : The Walden House Day Treatment Program

Although not well represented in the literature, day treatment programs targeting substance abuse problems have increased in both number and acceptability in recent years. This article reports on a day treatment program based on the Therapeutic Community (TC), and on outcomes for a sample of substance abuse clients (n = 66) entering the program. Participants were interviewed early in treatment and 6 months after admission using the Addiction Severity Index (ASI) and other measures. Clients entering day treatment were demographically diverse, with serious substance-abuse problems and psychiatric morbidity. Median retention in day treatment was about 5 weeks, but many clients received a contiguous episode of residential treatment, so that the median for total time in treatment was 18 weeks. Clients located and interviewed at 6-month follow-up (n = 38) showed significant improvement in alcohol and drug use, legal and social problems, and psychiatric symptoms. Findings suggest that day treatment can be used effectively as a precursor to residential treatment and that some clients applying for residential treatment can be treated effectively in day treatment alone.     

Case Management as a Therapeutic Enhancement

ABSTRACT

Using a sample of 453 veterans who received substance abuse treatment and were randomly assigned to case management and non-case management, this study examined both proximal (aftercare participation) and distal (severity of legal problems) measures of treatment outcomes. Multivariate analyses reveal that case-managed subjects stay longer in aftercare services than non-case managed clients. The longer post-treatment aftercare was related to better outcomes in criminality. The length of aftercare participation was also significantly associated with employment and readiness for treatment.     

Treatment retention and 1 year outcomes for residential programmes in England

This paper reports changes in substance use behaviours at 1-year follow-up, and investigates the relationship between time in treatment and observed outcomes. A total of 408 clients were interviewed at intake to 23 residential treatment programmes, and 286 (70%) of these were interviewed at 1 year. Substantial improvements were found in terms of abstinence from opiates, psychostimulants and benzodiazepines. At 1 year, half of the clients were abstinent from heroin. Reductions in injecting, sharing injecting equipment, heavy drinking and criminal behaviour were found. Critical treatment thresholds were identified using multiple logistic regression analyses. Longer stays in treatment were predictive of better 1 year outcomes.     

Case management as a therapeutic enhancement: impact on post-treatment criminality

Using a sample of 453 veterans who received substance abuse treatment and were randomly assigned to case management and non-case management, this study examined both proximal (aftercare participation) and distal (severity of legal problems) measures of treatment outcomes. Multivariate analyses reveal that case-managed subjects stay longer in aftercare services than non-case managed clients. The longer post-treatment aftercare was related to better outcomes in criminality. The length of aftercare participation was also significantly associated with employment and readiness for treatment.     

The value of acupuncture detoxification programs in a substance abuse treatment system

Our purpose is to compare baseline characteristics and detoxification readmission rates of clients treated at outpatient acupuncture programs and at short-term residential programs, two options available to persons seeking substance abuse detoxification. This was a retrospective cohort study using data on clients discharged from publicly funded detoxification programs in Boston between January 1993 and September 1994. Multivariate models were used to examine the effect on 6-month detoxification readmission rates of treatment at residential detoxification programs (used by 6,907 clients) versus at outpatient acupuncture programs (used by 1,104 clients) after adjusting for baseline differences. Acupuncture clients were less likely to be readmitted for detoxification within 6 months (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.53–0.95). Similar results were found when the analysis was performed on a subsample of clients that were relatively similar in terms of baseline characteristics (OR 0.61, 95% CI 0.39–0.94). We determined that acupuncture detoxification programs are a useful component of a substance abuse treatment system.     

Does centralized intake improve drug abuse treatment outcomes?

This study was designed to assess whether centralized intake and assessment in a drug abuse treatment system would lead to improved outcomes. Clients entering treatment through a centralized intake unit (CIU) or through individual programs (non-CIU) were interviewed at admission, and at 1 month and 1 year postadmission. Interviews included measures of treatment access and satisfaction, psychiatric symptoms, social support, and Addiction Severity Index composite scores. At treatment entry, CIU participants had more employment and psychological problems and lower social support, were more often required to be in treatment, and were more often placed on a waiting list. In analyses controlling for baseline differences between groups, there were main effects of time, but no CIU status effects or CIU status by time interactions. The CIU may have improved access to treatment for a more disabled population; however, clients entering treatment through the CIU did not have better outcomes than those entering treatment directly.     

Therapeutic community treatment for substance abusers with antisocial personality disorder.

This study compared treatment outcomes of substance abusers with and without antisocial personality disorder (APD) randomly assigned to two therapeutic communities, differing primarily in length of inpatient and outpatient treatment. We hypothesized that APD clients would be less likely to complete treatment, more likely to test positive for drugs and recidivate at follow-up, and that APD clients in the Standard program would have more favorable outcomes than those in the Abbreviated Inpatient program, because of the Standard program's longer inpatient treatment. Self-reports and objective measures of criminal activity and substance abuse were collected at pre- and posttreatment interviews. APD clients were as likely to complete treatment as other clients, and they exhibited the same patterns of reduced drug use and recidivism as did non-APD clients. Treatment program attended was unrelated to outcomes. Substance abusers diagnosed with APD can benefit from treatment in a therapeutic community combined with outpatient care.     

Role of social support and self-efficacy in treatment outcomes among clients with co-occurring disorders

Individuals with co-occurring substance use and psychiatric disorders have a more severe clinical course and poorer outcomes than do individuals with one disorder. In an attempt to find intervening variables that may contribute to improvement in treatment outcomes among individuals with co-occurring disorders, we investigated the roles of social support and self-efficacy in a sample of 351 clients with co-occurring disorders in residential drug abuse treatment programs (53% male; 35% African American, 13% Hispanic). Given their demographic variability, we also explored how ethnicity and age influence self-efficacy and access to social support, as well as their relationships to the outcomes. Structural equation modeling was used to examine the impact of the demographics and baseline psychological status, substance use, social support, and self-efficacy on mental health and substance use outcomes 6 months after treatment entry. Time in treatment was included as a control. Greater social support at baseline predicted better mental health status and less heroin and cocaine use; greater self-efficacy predicted less alcohol and cocaine use. Older clients reported less social support. African-American ethnicity was associated with more cocaine use at baseline and follow-up; however, African Americans reported more self-efficacy, which moderated their cocaine use. The current study highlights the potential therapeutic importance of clients' personal resources, even among a sample of severely impaired individuals.     

Abstracts of the AMERSA national conference,November 1999: Empirical studies

ABSTRACT

Clinician training and supervision are needed to transfer evidence-based practices to community-based treatment organizations. Standardized patients (SPs) are used for clinician training and evaluating. However, to be effective for substance abuse counselors, SPs must realistically portray substance abuse treatment clients. The current study assessed authenticity of SPs as substance abuse treatment clients. Twenty-one substance abuse counselors interviewed SP(s) with differing profiles. Counselors provided quantitative and qualitative ratings of SP authenticity. Counselor responses to the study procedures were analyzed as well. Quantitative results include high-authenticity ratings for the SPs but counselors' subjective responses varied. Counselor's rated the experience of participating in the study positively and provided constructive comments for future applications of this methodology. Results support future work on SPs as teaching and evaluation tools in substance abuse counseling. Findings also illustrate the need to refine definitions of authenticity for SPs as substance abuse clients.     

Substance abuse treatment and the recurrence of maltreatment among caregivers with children living at home: a propensity score analysis

Policy and programmatic initiatives of the last decade have focused on increased coordination of services and expansion of prompt substance abuse treatment for mothers initially involved with child welfare services (CWS). Yet, little evidence has been amassed concerning the implications of this approach on the recurrent need for CWS. Data are from a large national probability sample of children and their caregivers involved with CWS following an allegation of maltreatment. Data include the recurrence of maltreatment reports for this group of children who remain at home. Selected from 1,101 caregivers with an indicated substance abuse problem, a group of 224 clients who did not receive services were compared with 224 treated clients. Event history analyses showed that clients who received substance abuse treatment were nearly twice as likely to have another child abuse report within 18 months. Reasons why participation in substance abuse treatment may result in greater involvement with CWS are posited.     

Client-service matching in substance abuse treatment for women with children

This article addresses the relation between services matched to client-identified needs and substance abuse treatment outcomes for women with children. The study uses data collected for a program evaluation of an enhanced substance abuse services program for mothers involved with the child welfare system. In-person surveys were conducted with 183 women who were currently attending, or had recently completed substance abuse treatment. Bivariate tests and multivariate logistic regression models were conducted to assess the association between matched client-identified service needs and two treatment outcomes: substance use and satisfaction with treatment. Matched counseling services (domestic violence services, family counseling) were associated with reports of reduced substance use; matched ancillary services (housing, job training, legal services) were associated with clients' satisfaction with treatment. However, the total number of services clients received had a stronger relationship to treatment outcomes than did services matched to client-identified needs.     

Evaluation of the Washington State Access to Recovery project: Effects on Medicaid costs for working age disabled clients

In 2004, the federal government made a major commitment to support expanded substance abuse (SA) recovery services by initiating the Access to Recovery (ATR) program. The initial ATR I program awarded grants to 14 states, including Washington State. We evaluated Washington's ATR I program to determine its effect on Medicaid costs for working age disabled clients. We compared per member per month (PMPM) Medicaid costs during 1 year follow-up for clients who received ATR services (N = 1,347) with costs for a matched comparison group of 1,243 clients and used multiple regression techniques to estimate changes in Medicaid costs associated with ATR. ATR was found to be associated with reductions in PMPM Medicaid costs of $66 (p = .11) to $136 (p = .05) depending upon months of Medicaid eligibility. Recovery services aimed at facilitating engagement in SA treatment and aftercare appear to foster modest savings in Medicaid costs for working age disabled clients.
