"Intensive" outpatient substance abuse treatment: comparisons with "traditional" outpatient treatment

Polysubstance Use Among Pregnant Women With Opioid Use Disorder in the United States, 2007-2016

OBJECTIVE

To assess trends in polysubstance use among pregnant women with opioid use disorder in the United States.

METHODS

We conducted a time trend analysis of pooled, cross-sectional data from the National Inpatient Sample, an annual nationally representative sample of U.S. hospital discharge data. Among 38.0 million females aged 15-44 years with a hospitalization for delivery from 2007 to 2016, we identified 172,335 pregnant women with an International Classification of Diseases, Ninth Revision, Clinical Modification or International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis of opioid use disorder. Polysubstance use among pregnant women with opioid use disorder was defined as at least one co-occurring diagnosis of other substance use, including alcohol, amphetamine, cannabis, cocaine, sedative, or tobacco. We fit weighted multivariable logistic regression models to produce nationally representative estimates, including an interaction between year and rural compared with urban county of residence; controlled for age, race, and insurance type. Average predicted probabilities and 95% CIs were derived from regression results.

RESULTS

Polysubstance use among women with opioid use disorder increased from 60.5% (95% CI 58.3-62.8%) to 64.1% (95% CI 62.8%-65.3%). Differential time trends in polysubstance use among women with opioid use disorder were found in rural compared with urban counties. Large increases in amphetamine use occurred among those in both rural and urban counties (255.4%; 95% CI 90.5-562.9% and 150.7%; 95% CI 78.2-52.7%, respectively), similarly to tobacco use (30.4%; 95% CI 16.9-45.4% and 23.2%; 95% CI 15.3-31.6%, respectively). Cocaine use diagnoses declined among women with opioid use disorder at delivery in rural (-70.5%; 95% CI -80.4% to -55.5%) and urban (-61.9%; 95% CI -67.6% to -55.1%) counties. Alcohol use diagnoses among those with opioid use disorder declined -57% (95% CI -70.8% to -37.7%) in urban counties but did not change among those in rural counties.

CONCLUSION

Over the past decade, polysubstance use among pregnant women with opioid use disorder has increased more rapidly in rural compared with urban counties in the United States, with amphetamines and tobacco use increasing most rapidly.

Intensive Outpatient Treatment (IOP) of Behavioral Health (BH) Problems: Engagement Factors Predicting Subsequent Service Utilization

The purpose of the study is to 1) better understand patterns of utilization of Intensive Outpatient Treatment (IOP) Programs and Services in the State of Connecticut by adult Medicaid recipients experiencing a serious mental illness, substance use disorder, or co-occurring disorders; and 2) to determine the relationship between the duration of an IOP episode and connection to care rates for higher (i.e., rehospitalization) or lower levels of care following discharge. We hypothesized that the duration of an IOP episode would impact positively in reducing the use of higher levels of care while increasing the use of lower levels of care. In order to examine the frequency and duration of use of Intensive Outpatient (IOP) services by the CT Medicaid population, a two-year timeframe was selected: July 1, 2012 to June 30, 2014. A survival analysis was conducted to assess the risk of readmission to an IOP within 180 days based on demographic and utilization factors including, Age (in years on date of discharge), Race and Ethnicity, Gender, Homeless Status (at least one day in CY 2013), and Engagement Group (Intent to Treat, Early Termination, Minimally Adequate Dosage, & Target or More). To better understand the patterns of utilization associated with Adult IOP services, the average length of stay, number of treatment days, and average number of treatment days per week were explored. The number of unique individuals who were part of this analysis is 11,473, of which 2050 were mental health IOP utilizers (18%), 4598 were co-occurring IOP utilizers (40%), and 4825 (42%) were substance use IOP utilizers. For the total population, the average length of stay (ALOS) in days was 42 and the average number of treatment days attended per week was 2.5, for an average of 15 treatment days per episode of care. Among the IOP Cohorts, the Mental Health Cohort had the longest ALOS at 44.15 days, an average of 2.34 days of service per week, for an average of 14.76 days of IOP service per episode of care. The Substance Use Cohort had the shortest ALOS at 41.33 days, but had the highest intensity of services per week at 2.71 for an average of 16 days of service per episode of care. The Co-Occurring Cohort presented an ALOS of 41.74 days, an average of 2.32 services per week and an average of 13.83 sessions per episode. Overall there is evidence supporting an association between the number of days of care and protection from hospitalization, up to a certain number of days of care or number of days in IOP. Above the Minimally Adequate Dosage, the IOP protection factor seems to reach a plateau. This means that after 16 days of care, the chances of hospitalization remain the same regardless of the additional days provided.

On my own terms: Motivations for self-treating opioid-use disorder with non-prescribed buprenorphine

INTRODUCTION

The opioid overdose crisis in the United States has prompted an expansion of treatment services, including pharmacotherapy with buprenorphine. However, many people who use illicit opioids (PWUIO) self-treat their opioid-use disorder (OUD) with non-prescribed buprenorphine (NPB) in lieu of attending formal treatment. The present study aims to qualitatively understand motivations of people who are self-treating their OUD with NPB.

METHODS

Qualitative study designed to supplement and contextualize quantitative findings from natural history study of buprenorphine diversion, self-treatment, and use of substance use disorder treatment services. Interviews were audio-recorded, transcribed, systematically coded and analyzed via Iterative Categorization.

STUDY SETTING

The Dayton, Ohio metropolitan area in the midwestern United States; a site previously characterized as high impact in the national opioid overdose crisis.

PARTICIPANTS

Sixty-five individuals (35 men and 30 women) who met the DSM-5 criteria for OUD (moderate or severe) and had used NPB at least one time in the six months prior to their intake interview.

RESULTS

Participants described four key motivators for self-treating with NPB: perceived demands of formal treatment, the desire to utilize non-prescribed buprenorphine in combination with a geographic relocation, to self-initiate treatment while preparing for formal services, and to bolster a sense of self-determination and agency in their recovery trajectory.

CONCLUSIONS

Use of NPB is a recognized self-treatment modality among PWUIO, with some PWUIO transitioning into sustained recovery episodes or enrollment in formal treatment. Understanding the motivations for opting out of treatment is crucial for improving forms of care for people with OUD.

The treatment of cocaine use disorder

Cocaine use continues to be a serious worldwide public health problem. Cocaine abuse is associated with substantial morbidity and mortality. Cocaine overdose deaths are increasing in the United States and, in certain populations, outnumber heroin and opiate overdose deaths. Psychosocial treatments remain the treatments of choice for cocaine use disorder (CUD), with standard approaches including contingency management and cognitive behavioral therapy. However, the effect sizes of these treatments are not large, and they are not effective for most patients. Consequently, investigators have sought to develop pharmacological agents to augment the efficacy of psychosocial treatments. Despite these efforts, no medications have yet been proven to be safe and effective for the treatment of CUD. The most promising pharmacological strategies for CUD treatment thus far include the use of dopamine agonists, such as long-acting amphetamine and modafinil or glutamatergic and GABAergic agents such as topiramate. Combination drugs may be especially promising.

Substance abuse intensive outpatient programs: assessing the evidence

OBJECTIVE

Substance abuse intensive outpatient programs (IOPs) are direct services for people with substance use disorders or co-occurring mental and substance use disorders who do not require medical detoxification or 24-hour supervision. IOPs are alternatives to inpatient and residential treatment. They are designed to establish psychosocial supports and facilitate relapse management and coping strategies. This review assessed the evidence base for IOPs.

METHODS

Authors searched major databases: PubMed, PsycINFO, Applied Social Sciences Index and Abstracts, Sociological Abstracts, Social Services Abstracts, Published International Literature on Traumatic Stress, ERIC, and CINAHL. They identified 12 individual studies and one review published between 1995 and 2012. They chose from three levels of research evidence (high, moderate, and low) based on benchmarks for the number of studies and quality of their methodology. They also described evidence of service effectiveness.

RESULTS

Based on the quality of trials, diversity of settings, and consistency of outcomes, the level of evidence for IOPs was rated high. Multiple randomized trials and naturalistic analyses that compared IOPs with inpatient or residential care found comparable outcomes. All studies reported reductions in alcohol and drug use. However, substantial variability in the operationalization of IOPs and outcome measures was apparent.

CONCLUSIONS

IOPs are an important part of the continuum of care for substance use disorders. They are as effective as inpatient treatment for most individuals. Public and commercial health plans should consider IOP services as a covered health benefit. Standardization of the elements included in IOPs may improve their quality and effectiveness.

A randomized trial of intensive outpatient (IOP) vs. standard outpatient (OP) buprenorphine treatment for African Americans

BACKGROUND

Buprenorphine is increasingly being used in community-based treatment programs, but little is known about the optimal level of psychosocial counseling in these settings. The aim of this study was to compare the effectiveness of OP and IOP level counseling when provided as part of buprenorphine treatment for opioid-dependent African Americans.

METHODS

Participants were African American men and women starting buprenorphine treatment at one of two community-based clinics (N=300). Participants were randomly assigned to OP or IOP. Measures at baseline, 3- and 6-month included the primary outcome of DSM-IV opioid and cocaine dependence criteria, as well as additional outcomes of illicit opioid and cocaine use (urine test and self-report), criminal activity, retention in treatment, Quality of Life, Addiction Severity Index composite scores, and HIV risk behaviors.

RESULTS

Participants assigned to OP received, on average, 3.67 (SD=1.30)h of counseling per active week in treatment. IOP participants received an average of 5.23 (SD=1.68)h of counseling per active week (less than the anticipated 9h per week of counseling). Both groups showed substantial improvement over a 6-month period on nearly all measures considered. There were no significant differences between groups in meeting diagnostic criteria for opioid (p=.67) or cocaine dependence (p=.63). There were no significant between group differences on any of the other outcomes. A secondary analysis restricting the sample to participants meeting DSM-IV criteria for baseline cocaine dependence also revealed no significant between-group differences (all ps>.05).

CONCLUSIONS

Buprenorphine patients receiving OP and IOP levels of care both show short-term improvements.

Longitudinal Substance Use following an Emergency Department Visit for Cocaine-Associated Chest Pain

Substance abuse is a chronic, relapsing condition, yet some individuals over time seem to cease use for factors that are largely unclear. A life threatening episode of cocaine-associated chest pain requiring an emergency department (ED) visit may influence subsequent use. A consecutive cohort (n = 219) of patients who presented to a large, urban ED with cocaine-associated chest pain was interviewed at baseline, three months, six months, and 12 months to evaluate longitudinal rates of subsequent drug use. Overall, there was a significant decrease in cocaine use over time (baseline = 100.0%, three months = 56.5%, six months = 54.2%, and 12 months = 51.7%, p < .05 for baseline versus each follow-up interval). Findings suggest that substance use declines following an ED visit for cocaine-related chest pain. However, about half of the subjects were still using cocaine one year later. Future studies examining the potential impact of brief interventions or case management to intervene with this not-in-treatment ED population are warranted.

Co-occurring disorders in substance abuse treatment: issues and prospects

This article explores the epidemiology of co-occurring disorders (CODs) with an emphasis on the implications of study findings for the functioning and potential of substance abuse treatment. Severity of disorder is discussed as an issue that may have particular significance for the selection of specialized as opposed to traditional substance abuse treatment forms. Exploration is made, as well, of the resources currently available to substance abuse treatment, especially the human resources available, and the implications of resource availability for undertaking initiatives specific to COD. Findings from standard and enhanced treatment for comorbid individuals are examined in an effort to clarify areas of need for specialized and typical treatment personnel. Issues are raised for consideration by the clinical research and treatment provider communities in terms of assessment and diagnosis, manpower and training, and response to the challenge of relapse in this population.

Recognition and management of depression in a substance use disorder treatment population

This study examines the association between depressive symptomatology and return to substance use among a sample of 126 veterans consecutively admitted to treatment at a VA intensive outpatient program for substance use disorders. Controlling for numerous demographic and health-related covariates, depressive symptomatology measured at treatment exit with a Beck Depression Inventory (BDI) was significantly predictive of substance use at three-months post-treatment (p < .05). Analysis with a recoded BDI showed that the moderately-to-severely symptomatic (BDI = 20+) were 4.1 times more likely to have returned to substance use than those with a BDI score of under 20.

Differential effectiveness of residential versus outpatient aftercare for parolees from prison-based therapeutic community treatment programs

BACKGROUND

Research has indicated that more intense treatment is associated with better outcomes among clients who are appropriately matched to treatment intensity level based on the severity of their drug/alcohol problem. This study examined the differential effectiveness of community-based residential and outpatient treatment attended by male and female drug-involved parolees from prison-based therapeutic community substance abuse treatment programs based on the severity of their drug/alcohol problem.

METHODS

Subjects were 4,165 male and female parolees who received prison-based therapeutic community substance abuse treatment and who subsequently participated in only outpatient or only residential treatment following release from prison. The dependent variable of interest was return to prison within 12 months. The primary independent variables of interest were alcohol/drug problem severity (low, high) and type of aftercare (residential, outpatient). Chi-square analyses were conducted to examine the differences in 12-month RTP rates between and within the two groups of parolees (residential and outpatient parolees) based on alcohol/drug problem severity (low severity, high severity). Logistic regression analyses were performed to determine if aftercare modality (outpatient only vs. residential only) was a significant predictor of 12-month RTP rates for subjects who were classified as low severity versus those who were classified as high severity.

RESULTS

Subjects benefited equally from outpatient and residential aftercare, regardless of the severity of their drug/alcohol problem.

CONCLUSION

As states and the federal prison system further expand prison-based treatment services, the demand and supply of aftercare treatment services will also increase. As this occurs, systems and policies governing the transitioning of individuals from prison- to community-based treatment should include a systematic and validated assessment of post-prison treatment needs and a valid and reliable means to assess the quality of community-based treatment services. They should also ensure that parolees experience a truly uninterrupted continuum of care through appropriate recognition of progress made in prison-based treatment.

Unmet needs for comprehensive services in outpatient addiction treatment

Many addiction treatment patients suffer from health and psychosocial problems in addition to substance misuse at the time of their treatment entry. Outpatient treatment programs have attempted to address these problems by providing or facilitating access to comprehensive health and social services. Nevertheless, previous research have suggested high levels of unmet needs for these services in the addiction treatment population. Using data from a large study on community-based outpatient addiction treatment, this article provides additional information on levels of unmet service needs and the relationship between need and receipt of services during treatment. Our results suggest extremely high levels of unmet needs for a wide variety of health and psychosocial services. Specifically, the data suggest that unmet service needs may be far more prevalent than previous estimates and that addiction treatment populations in rural areas may be particularly disadvantaged.

Pathological Gambling, Comorbidities and Treatment Outcome: Is the Bronze Standard Good Enough? A Case Study

The paper presents a case study of our attempt to design an outcome package for a program including pathological gamblers and their comorbidities. The clinical intricacies involved highlight the limitations of the clinical trial and the need for alternate designs aimed at assessing effectiveness.

Impact of Patient Placement Criteria on Substance Abuse Treatment Under the Oregon Health Plan

When Oregon shifted to managed care for Medicaid-funded substance abuse treatment, standardized patient placement and discharge criteria were rapidly implemented statewide. This prospective, naturalistic study examines the validity and impact of placement criteria with a sample of 240 adults presenting for treatment compared to a sample of 287 in Washington state, where implementation was phased in slowly. Baseline profile analysis suggested better differentiation between Level II and Level III clients for the Oregon sample and better implementation than with the Washington sample, presumably because Oregon clinicians received more training and had more experience with the criteria. A majority of the Oregon sample was placed in intensive outpatient programs, consistent with the recommended level of care. In this study, placement criteria showed good potential for changing treatment planning behavior, increasing individualization, and improving utilization of new levels of care.

Employment outcomes for hard-to-reach persons with chronic and severe substance use disorders receiving assertive community treatment

Many persons with chronic and severe substance use disorders (SUDs) enter and exit public substance dependence treatment systems with limited benefit, but continue overuse of high-cost health and human services. Less than a third holds jobs, earning income below U.S. federal poverty levels. Long-term integrated substance dependency treatment, rehabilitation, and support services will be essential to resolve substance dependence and employment problems. This single-group program evaluation reports adaptation of Assertive Community Treatment (ACT), a multi-component, team-based service model originally designed for persons with severe mental illnesses and multiple disabilities, for effectiveness with persons with severe SUDs. The ACT model delivers an integrated package of treatment, rehabilitation, and support to reduce substance misuse and increase employment. Of the 35 clients admitted 12 months prior to conclusion of this 2-year service demonstration, only one left treatment prematurely. Generally, clients modestly reduced substance misuse and increased employment. However, the evaluation design and small sample limit inferences of causation and generalizability of these promising outcomes. Persuading states to adopt expensive team-based approaches for this population will require firm evidence of favorable cost-benefit ratios.

Potential barriers to work for substance-abusing women on welfare. Findings from the CASAWORKS for Families pilot demonstration

AIM

To assess the prevalence and relationship to later employment of potential barriers to work for substance-abusing women on Temporary Assistance to Needy Families (TANF) enrolled in a multiservice welfare-to-work program.

DESIGN

A field study with repeated measures and intent-to-treat sampling.

INTERVENTION

The CASAWORKS for Families (CWF) was delivered in 11 sites in nine states across the nation and featured integration of substance-abuse treatment and employment and work readiness services.

MEASUREMENT

The Addiction Severity Index, supplemented with subject-appropriate questions.

SAMPLE

A total of 366 CWF women who completed interviews at program enrollment, and at 6 and 12 months later.

FINDINGS

Substance-abusing women on TANF in the CWF program exhibited multiple potential barriers to work at enrollment, averaging 6 out of 14 potential barriers assessed. They reported significantly more obstacles than a general welfare sample of women from the same locales. Few single barriers were significantly related to employment at 12 months. However, the total number of potential barriers to work experienced, particularly at 6 months, was related to employment at 12 months.

One-year outcomes from the CASAWORKS for Families intervention for substance-abusing women on welfare

AIM

To evaluate the effectiveness of a multiservice intervention designed to move substance-abusing women on welfare to sobriety and self-sufficiency by addressing their substance abuse, domestic violence, employment, and basic needs.

DESIGN

A field evaluation with repeated measures at 6 and 12 months on an intent-to-treat sample of 529 women conducted in 11 selected sites across the country. There were significant improvements shown in substance use and family and social functioning by the 6-month point, and additional improvements in employment by the 12-month point. By 12 months, more than 46% were abstinent from alcohol and other drugs, and 30% were employed at least part-time. There were only modest improvements shown in the medical and psychiatric status of these women. These preliminary findings suggest that site-level interagency coordination and program-level case management were associated with improvements in the targeted areas as predicted by the model. Future work will require a more closely specified, manual-guided form of the intervention plus the inclusion of control groups and cost measures to fully evaluate the cost benefits from the final form of the intervention.

Depressive symptomatology and early attrition from intensive outpatient substance use treatment

This study examines the relationship between depressive symptoms and attrition from outpatient treatment in a Veterans Affairs facility that had recently moved to intensive outpatient-only treatment for substance abuse. This article focuses on 126 consecutively admitted patients who were enrolled on their last day of a 3- to 4-day outpatient detoxification. Results indicate that severe depressive symptomatology presenting at treatment entry is a significant risk factor for early attrition from intensive outpatient substance use treatment but not later attrition. These data indicate that retention efforts should be directed toward the assessment and management of depressive symptoms early in the treatment process, with interventions targeted to those who report severe symptomatology. The results also indicate that future research should focus on potential distinguishing characteristics between early and later attrition.

The effectiveness of two intensities of psychosocial treatment for cocaine dependence

Structured treatments for cocaine dependence have been shown to be effective despite high attrition rates. What is unclear is what level of treatment intensity is needed to improve and sustain patient outcomes, especially among low SES urban residents. This study evaluated whether there were differences between two levels of treatment intensities for cocaine dependence in reducing substance use and improving health and social indicators. Ninety-four cocaine dependent predominantly African-American male veterans were randomly assigned to either a 12 h/week day hospital program (DH12) or a 6 h/week outpatient program (OP6) and were evaluated at baseline, during treatment and at 4 and 7 months post-treatment. Both treatments stressed abstinence, behavior change and prosocial adjustment and only differed in level of treatment intensity. During treatment measures included urine toxicologies, program attendance, treatment completion and aftercare attendance. Participants reported a 52% reduction in days of cocaine use and experienced significant improvements in employment and psychiatric functioning at seven months post-treatment. However, there was no significant difference between the DH12 and OP6 programs in terms of abstinence during treatment, treatment completion, treatment or aftercare attendance or any Addiction Severity Index (ASI)-related variable assessing level of functioning at 4 and 7 months. While future research with a larger community-based sample that includes female clients is necessary, the current findings demonstrate that a 6 h/week program is just as effective and thus has a significant cost savings compared to a 12 h/week treatment modality for cocaine dependence.

The relationship of counseling and self-help participation to patient outcomes in DATOS

Using a sample of 927 cocaine patients enrolled in programs in three modalities included in the national Drug Abuse Treatment Outcome Studies (DATOS), this investigation examined the relationship of three dimensions of treatment process on after-treatment cocaine and heavy alcohol use and predatory illegal activity. Logistic regression revealed significant reductions in all three outcomes and strong effects of treatment duration and after-treatment self-help, conditional on the modality. Results did not support the hypothesized relationship between treatment outcomes and amounts of counseling and during-treatment self-help. Findings support the robustness of duration effects and after-treatment self-help and contribute to the measurement methodology for calibrating treatment intensity. The strong after-treatment self-help effect in the two residential and inpatient modalities suggests these programs can improve treatment outcomes by making referral to after-treatment self-help participation a standard practice and installing mechanisms to increase the likelihood of attendance at least twice weekly during the year after treatment.

Does clinical case management improve outpatient addiction treatment

This project evaluated whether clinical case managers (CCMs) could increase access and utilization of social services in the community; and thereby improve outcomes of addiction treatment. No case management (NoCM)--patients received standard, group-based, abstinence-oriented, outpatient drug abuse counseling, approximately twice weekly. Clinical case management (CCM)--patients were treated in the same programs but also were assigned a CCM who provided access to pre-contracted, support services such as drug free housing, medical care, legal referral, and parenting classes from community agencies. CCM patients received more alcohol, medical, employment, and legal services than NoCM patients during treatment. At 6 month follow-up CCM patients showed significantly more improvement in alcohol use, medical status, employment, family relations, and legal status than NoCM patients. We conclude that CCM was an effective method of improving outcomes for substance abuse patients in community treatment programs. Essential elements for successful implementation included extensive training to foster collaboration; and pre-contracting of services to assure availability.

Methodological and clinical challenges in evaluating treatment outcome of substance-related disorders and comorbidity

OBJECTIVE

To review the steps required to develop an outcome evaluation package and to report on the 12-month outcome of an integrated day program.

METHOD

Based on the identification of salient outcome predictors, standardized instruments were selected. A cohort of 78 patients was assessed at the time of admission to the program, at discharge, and 3, 6, and 12 months afterward.

RESULTS

Improvements were sustained over 1 year in all areas including treatment needs, quality of life, and readiness to change.

CONCLUSIONS

The gap between the "cultures" of treatment and research must be narrowed. Following evidence of a program's general effectiveness through outcome monitoring, a randomized control design is optimal for specific interventions. The optimal length of follow-up depends on the perceived confounds.
