Contingency Management for Stimulant Use Disorder: Progress, Challenges, and Recommendations.

The United States is currently in the fourth wave of the overdose crisis wherein stimulants together with fentanyl are the major drivers of overdose deaths. To date, there has been limited effort outside the US Veterans Administration Health System health system to disseminate evidence-based treatment for people with stimulant use disorder. Contingency management, a behavioral intervention in which positive reinforcement is provided for a target behavior indicating treatment progress, has decades of empirical support but limited implementation in real-world, non-US Veterans Administration Health System settings. The purpose of the report is to provide an overview of contingency management, the barriers to adoption, and recommendations for overcoming these barriers.

Promoting Adoption of Medication for Opioid and Alcohol Use Disorders Through System Change.

OBJECTIVE: The Medication Research Partnership (MRP), a collaboration between a national commercial health plan and nine addiction treatment centers, implemented organizational and system changes to promote use of federally approved medications for treatment of alcohol and opioid use disorders. METHOD: A difference-in-differences analysis examined change over time in the percentage of patients receiving a prescription medication for alcohol or opioid use disorders treated in MRP (n = 9) and comparison (n = 15) sites. RESULTS: MRP clinics experienced a 2.4-fold increase in patients receiving an alcohol or opioid prescription (13.2% at baseline to 31.7% at 3 years after MRP initiation); comparison clinics experienced significantly less change (17.6% to 23.5%) with an adjusted difference-in-differences of 12.5% (95% CI [5.4, 19.6], p = .001). MRP sites increased the patients with prescriptions to treat opioid use disorder from 17.0% (baseline) to 36.8% (3 years after initiation), with smaller changes observed in comparison sites (23.2% to 24.0%) and a 3-year post-initiation adjusted difference-in-differences of 19% (95% CI [8.5, 29.5], p = .000). Medications for alcohol use disorders increased in both MRP (9.0% to 26.5%) and comparison sites (11.4% to 23.1%). CONCLUSIONS: Promoting the use of medications to support recovery required complex interventions. The Advancing Recovery System Change Model, initially developed in publicly funded systems of care, was successfully adapted for commercial sector use. The model provides a framework for providers and commercial health plans to collaborate and increase patient access to medications.

Specifying and Pilot Testing Quality Measures for the American Society of Addiction Medicine's Standards of Care.

OBJECTIVES: In 2013, the American Society of Addiction Medicine (ASAM) approved its Standards of Care for the Addiction Specialist Physician. Subsequently, an ASAM Performance Measures Panel identified and prioritized the standards to be operationalized into performance measures. The goal of this study is to describe the process of operationalizing 3 of these standards into quality measures, and to present the initial measure specifications and results of pilot testing these measures in a large health care system. By presenting the process rather than just the end results, we hope to shed light on the measure development process to educate, and also to stimulate debate about the decisions that were made. METHODS: Each measure was decomposed into major concepts. Then each concept was operationalized using commonly available administrative data sources. Alternative specifications examined and sensitivity analyses were conducted to inform decisions that balanced accuracy, clinical nuance, and simplicity. Using data from the US Veterans Health Administration (VHA), overall performance and variation in performance across 119 VHA facilities were calculated. RESULTS: Three measures were operationalized and pilot tested: pharmacotherapy for alcohol use disorder, pharmacotherapy for opioid use disorder, and timely follow-up after medically managed withdrawal (aka detoxification). Each measure was calculable with available data, and showed ample room for improvement (no ceiling effects) and wide facility-level variability. CONCLUSIONS: Next steps include conducting feasibility and pilot testing in other health care systems and other contexts such as standalone addiction treatment programs, and also to study the specification and predictive validity of these measures.

A Systematic Review on the Use of Psychosocial Interventions in Conjunction With Medications for the Treatment of Opioid Addiction.

Opioid use and overdose rates have risen to epidemic levels in the United States during the past decade. Fortunately, there are effective medications (ie, methadone, buprenorphine, and oral and injectable naltrexone) available for the treatment of opioid addiction. Each of these medications is approved for use in conjunction with psychosocial treatment; however, there is a dearth of empirical research on the optimal psychosocial interventions to use with these medications. In this systematic review, we outline and discuss the findings of 3 prominent prior reviews and 27 recent publications of empirical studies on this topic. The most widely studied psychosocial interventions examined in conjunction with medications for opioid addiction were contingency management and cognitive behavioral therapy, with the majority focusing on methadone treatment. The results generally support the efficacy of providing psychosocial interventions in combination with medications to treat opioid addictions, although the incremental utility varied across studies, outcomes, medications, and interventions. The review highlights significant gaps in the literature and provides areas for future research. Given the enormity of the current opioid problem in the United States, it is critical to gain a better understanding of the most effective ways to deliver psychosocial treatments in conjunction with these medications to improve the health and well-being of individuals suffering from opioid addiction.

Extended-Release Naltrexone: A Qualitative Analysis of Barriers to Routine Use.

The Medication Research Partnership (a national health plan and nine addiction treatment centers contracted with the health plan) sought to facilitate the adoption of pharmacotherapy for alcohol and opioid use disorders. Qualitative analysis of interviews with treatment center change leaders, individuals working for the manufacturer and its technical assistance contractor, and health plan managers extracted details on the processes used to order, store, bill for, and administer extended-release naltrexone. Qualitative themes were categorized using domains from the Consolidated Framework for Implementation Research (intervention characteristics, outer setting, inner setting, and provider characteristics). Characteristics of XR-NTX that inhibited use included the complexity of ordering and using the medication; cost was also a barrier. Outer setting barriers reflected patient needs and external health plan policies on formulary coverage, benefit management, and reimbursement. Program structures, the lack of physician linkages, a culture resistant to the use of medication, and unease with change were inner setting elements that limited use of XR-NTX. Patient stereotypes and a lack of knowledge about XR-NTX affected practitioner willingness to treat patients and prescribe XR-NTX. The Consolidated Framework for Implementation Research provided a useful lens to understand and interpret the processes affecting access to XR-NTX.

Medicaid coverage of medications to treat alcohol and opioid dependence.

Substance use disorders affect 12% of Medicaid beneficiaries. The prescription drug epidemic and growing need for treatment of alcohol and opioid dependence have refocused states' attention on their provision of substance use disorder treatment services, including medications. This study characterized how Medicaid programs cover these treatment medications. Data were from 2013 Medicaid pharmacy documents, 2011 and 2012 Medicaid state drug utilization records, and a 2013 American Society of Addiction Medicine survey. Results showed that only 13 state Medicaid programs included all medications approved for alcohol and opioid dependence on their preferred drug lists. The most commonly excluded were extended-release naltrexone (19 programs), acamprosate (19 programs), and methadone (20 programs). For combined buprenorphine-naloxone, 48 Medicaid programs required prior authorization, and 11 programs used 1- to 3-year lifetime treatment limits. Given the chronic nature of substance use disorders and the overwhelming evidence supporting ongoing coverage for many of these medications, states may want to reexamine substance use disorder benefits.

Extended-release naltrexone for alcohol and opioid dependence: a meta-analysis of healthcare utilization studies.

Through improved adherence, once-monthly injectable extended-release naltrexone (XR-NTX) may provide an advantage over other oral agents approved for alcohol and opioid dependence treatment. The objective of this study was to evaluate cost and utilization outcomes between XR-NTX and other pharmacotherapies for treatment of alcohol and opioid dependence. Published studies were identified through comprehensive search of two electronic databases. Studies were included if they compared XR-NTX to other approved medicines and reported economic and healthcare utilization outcomes in patients with opioid or alcohol dependence. We identified five observational studies comparing 1,565 patients using XR-NTX to other therapies over 6 months. Alcohol dependent XR-NTX patients had longer medication refill persistence versus acamprosate and oral naltrexone. Healthcare utilization and costs was generally lower or as low for XR-NTX-treated patients relative to other alcohol dependence agents. Opioid dependent XR-NTX patients had lower inpatient substance abuse-related utilization versus other agents and $8170 lower total cost versus methadone.

Process-of-care measures as predictors of client outcome among a methamphetamine-dependent sample at 12- and 36-month follow-ups.

This study examines the utility of several process-of-care performance measures (initiation, engagement, retention, and monitoring of drug use during treatment) as predictors of methamphetamine (MA) use outcomes at 12- and 36-month follow-ups. MA-dependent individuals (n = 871) participated in a randomized, controlled trial of outpatient psychosocial treatment from 1999-2002 and completed 12- and 36-month follow-up interviews. This sample included a treatment-as-usual group (n = 436) and a 16-week Matrix treatment (n = 435) group. Significant associations were observed between select process-of-care measures and MA use outcomes at both follow-ups. While correlational analyses showed an association between MA abstinence at follow-up and enhanced treatment engagement and retention, mixed logistic regression analyses indicated that sustained abstinence from MA during outpatient treatment was the strongest predictor of testing negative for MA use at both follow-ups. Results suggest that monitoring client drug use during treatment may be a useful process-of-care measure with MA-dependent users.

Alcohol dependence treatments: comprehensive healthcare costs, utilization outcomes, and pharmacotherapy persistence.

OBJECTIVES: To determine the healthcare costs associated with treatment of alcohol dependence with medications versus no medication and across the 4 medications approved by the US Food and Drug Administration (FDA). STUDY DESIGN: Retrospective claims database analysis. METHODS: Eligible adults with alcohol dependence were identified from a large US health plan and the IMS PharMetrics Integrated Database. Data included all medical and pharmacy claims at all available healthcare sites. Propensity score-based matching and inverse probability weighting were applied to baseline demographic, clinical, and healthcare utilization variables for 20,752 patients, half of whom used an FDA-approved medication for alcohol dependence. A similar comparison was performed among 15,502 patients treated with an FDA-approved medication: oral acamprosate calcium (n = 8958), oral disulfiram (n = 3492), oral naltrexone (NTX) hydrochloride (n = 2391), or extended-release injectable naltrexone (XR-NTX; n = 661). Analyses calculated 6-month treatment persistence, utilization, and paid claims for: alcoholism medications, detoxification and rehabilitation, alcohol-related and nonrelated inpatient admissions, outpatient services, and total costs. RESULTS: Medication was associated with fewer admissions of all types. Despite higher costs for medications, total healthcare costs, including inpatient, outpatient, and pharmacy costs, were 30% lower for patients who received a medication for their alcohol dependence. XR-NTX was associated with greater refill persistence and fewer hospitalizations for any reason and lower hospital costs than any of the oral medications. Despite higher costs for XR-NTX itself, total healthcare costs were not significantly different from oral NTX or disulfiram, and were 34% lower than with acamprosate. CONCLUSION: In this largest cost study to date of alcohol pharmacotherapy, patients who received medication had lower healthcare utilization and total costs than patients who did not. XR-NTX showed an advantage over oral medications in treatment persistence and healthcare utilization, at comparable or lower total cost.

Cost and utilization outcomes of opioid-dependence treatments.

OBJECTIVES: To evaluate the healthcare costs associated with treatment of opioid-dependence disorder with medications versus no medication, and with the 4 agents approved by the US Food and Drug Administration (FDA). STUDY DESIGN: Retrospective claims database analysis. METHODS: Eligible adults with opioid dependence were identified from a large US health plan and the PharMetrics Integrated Database. Data included all medical and pharmacy claims at all available healthcare sites. Case-mix adjustment was applied using baseline demographic, clinical, and healthcare utilization variables for 13,316 patients; half of these patients used an FDA-approved medication for opioid dependence. A similar comparison was performed among 10,513 patients treated with extended-release naltrexone (NTX-XR) (n = 156) prior to FDA approval for opioid dependence or with a medication approved at the time: oral naltrexone (NTX) (n = 845), buprenorphine (n = 7596), or methadone (n = 1916). Analyses calculated 6-month persistence, utilization, and paid claims for opioid-dependence medications, detoxification and rehabilitation, opioid-related and non-related inpatient admissions, outpatient services, and total costs. RESULTS: Medication was associated with fewer inpatient admissions of all types. Despite higher costs for medications, total healthcare costs, including inpatient, outpatient, and pharmacy costs, were 29% lower for patients who received a medication for opioid dependence versus patients treated without medication. Patients given XR-NTX had fewer opioid-related and non-opioid-related hospitalizations than patients receiving oral medications. Despite higher costs for XR-NTX, total healthcare costs were not significantly different from those for oral NTX or buprenorphine, and were 49% lower than those for methadone. CONCLUSION: Patients with opioid dependence who received medication for this disorder had lower hospital utilization and total costs than patients who did not receive pharmacologic therapy. Patients who received XR-NTX had lower inpatient healthcare utilization at comparable or lower total costs than those receiving oral medications.

Advancing performance measures for use of medications in substance abuse treatment.

Performance measures have the potential to drive high-quality health care. However, technical and policy challenges exist in developing and implementing measures to assess substance use disorder (SUD) pharmacotherapy. Of critical importance in advancing performance measures for use of SUD pharmacotherapy is the recognition that different measurement approaches may be needed in the public and private sectors and will be determined by the availability of different data collection and monitoring systems. In 2009, the Washington Circle convened a panel of nationally recognized insurers, purchasers, providers, policy makers, and researchers to address this topic. The charge of the panel was to identify opportunities and challenges in advancing use of SUD pharmacotherapy performance measures across a range of systems. This article summarizes those findings by identifying a number of critical themes related to advancing SUD pharmacotherapy performance measures, highlighting examples from the field, and recommending actions for policy makers.

Improving the accountability of California's public substance abuse treatment system through the implementation of performance models.

Improving the care for individuals with substance use disorders is a national health policy priority. Like other parts of the health care system, the addiction field is under pressure for higher accountability-more efficient use of treatment resources, the delivery of quality services, and the production of positive client outcomes. This introductory article highlights the importance of the collection of articles being published in this special issue as they describe California's efforts toward making the alcohol and drug (AOD) treatment system more accountable and effective.

Comparison of healthcare utilization among patients treated with alcoholism medications.

OBJECTIVES: To determine in a large claims database the healthcare utilization and costs associated with treatment of alcohol dependence with medications vs no medication and across 4 US Food and Drug Administration (FDA)-approved medications. STUDY DESIGN: Claims database analysis. METHODS: Eligible adults with alcohol dependence claims (n = 27,135) were identified in a commercial database (MarketScan; Thomson Reuters Inc, Chicago, Illinois). Following propensity score-based matching and inverse probability weighting on demographic, clinical, and healthcare utilization variables, patients who had used an FDA-approved medication for alcohol dependence (n = 2977)were compared with patients who had not (n =2977). Patients treated with oral naltrexone hydrochloride(n = 2064), oral disulfiram (n = 2076), oral acamprosate calcium (n = 5068), or extended-release injectable naltrexone (naltrexone XR) (n = 295) were also compared for 6-month utilization rates of alcoholism medication, inpatient detoxification days, alcoholism-related inpatient days, and outpatient services, as well as inpatient charges. RESULTS: Patients who received alcoholism medications had fewer inpatient detoxification days (706 vs 1163 days per 1000 patients, P <.001), alcoholism-related inpatient days (650 vs 1086 days, P <.001), and alcoholism-related emergency department visits (127 vs 171, P = .005). Among 4 medications, the use of naltrexone XR was associated with fewer inpatient detoxification days (224 days per 1000 patients) than the use of oral naltrexone (552 days, P = .001), disulfiram (403 days, P = .049), or acamprosate (525 days, P <.001). The group receiving naltrexone XR also had fewer alcoholism-related inpatient days than the groups receiving disulfiram or acamprosate. More patients in the naltrexone XR group had an outpatient substance abuse visit compared with patients in the oral alcoholism medication groups. CONCLUSION: Patients who received an alcoholism medication had lower healthcare utilization than patients who did not. Naltrexone XR showed an advantage over oral medications in healthcare utilization and costs.

Evidence for substance abuse services and policy research: a systematic review of national databases.

We reviewed 39 national government- and nongovernment-sponsored data sets related to substance addiction policy. These data sets describe patients with substance use disorders (SUDs), treatment providers and the services they offer, and/or expenditures on treatment. Findings indicate the availability of reliable data on the prevalence of SUD and the characteristics of specialty treatment facilities, but meager data on financing and services. Gaps in information might be filled through agency collaboration to redesign, coordinate, and augment existing substance abuse and general health surveys. Despite noted gaps, these data sets represent an unusually rich set of resources for health services and policy research.

Outcomes, performance, and quality: what's the difference?

Calls for greater accountability within the addiction treatment field have led to a wide range of efforts designed to improve treatment performance, quality, and outcomes. However, efforts with conceptually and methodologically different approaches have used the same umbrella terms such as "quality," "performance indicators," and "outcome domains," causing substantial confusion among providers and policymakers. This article provides operational definitions of the terms used in discussing quality, performance, and outcomes, as well as a discussion of ways to integrate efforts to measure treatment system performance and quality during treatment with patient outcomes during and following treatment. This article thus helps build a common understanding about how these efforts to bring greater accountability can be combined and integrated to improve the attractiveness and effectiveness of addiction treatments.

Performance measures for alcohol and other drug services.

Performance measures, which evaluate how well health care practitioners' actions conform to practice guidelines, medical review criteria, or standards of quality, can be used to improve access to treatment and the quality of treatment for people with alcohol and other drug problems. This article examines different types of quality measures, how they fit within the continuum of care, and the types of data that can be used to arrive at these measures. The Washington Circle measures--identification, initiation of treatment, and treatment engagement--are a widely used set of performance measures.
