The Los Angeles County hub-and-provider network for promoting the sustained use of extended-release naltrexone (XR-NTX) in Los Angeles County (2010-2015).

Extended-release naltrexone (XR-NTX) is a medication-assisted treatment (MAT) that is used in conjunction with psychosocial treatment for substance use disorder. It is associated with a reduction in the number of days that patients use alcohol or opioids, in cravings and drug-seeking behaviors, and in healthcare utilization costs, as well as improved medication adherence rates for patients in substance use disorder (SUD) treatment programs and improved quality of life. Despite the clinical effectiveness of XR-NTX, its clinical use has been slow to develop. There is little research describing the utilization of XR-NTX over time at the treatment-system level and few documented attempts to promote MAT by creating a system to explicitly promote and sustain MAT use. This study examines changes between April 1, 2010, and March 30, 2015, in the utilization patterns of XR-NTX for SUDs as promoted and delivered in a system of "medication hubs," comprised of community providers and a medication coordinating center, and training efforts. This system was implemented as part of a large demonstration project that was designed to provide access to XR-NTX in Los Angeles County. Our findings indicated an increase in the initiation of XR-NTX (59% increase) and subsequent doses (89% increase) from Year 1 to Year 5 of the project (p<0.001). These findings suggest that it is possible to improve MAT utilization (in this case XR-NTX) through the use of a system of care that minimizes MAT payment issues for providers and patients, provides an infrastructure (medication hubs and SUD treatment providers), promotes system coordination, and educates providers.

Effectiveness of extended release naltrexone to reduce alcohol cravings and use behaviors during treatment and at follow-up.

Changes in cravings to drink alcohol and alcohol use behaviors were examined among 337 patients who were administered extended-release naltrexone (XR-NTX) in conjunction with psychosocial treatment in community-based substance use disorder treatment programs. Cravings and use behaviors were assessed at multiple time points (baseline; weeks 1, 2, and 3 after the first dose; monthly after the first four assessments; and at 30- and 60-days after the last dose). A total of 863 doses (M=2.6, SD=1.8) were administered and the majority of patients (65%) took more than one dose. Alcohol craving scores decreased from 19 to 5.7 after the first dose of XR-NTX. Days of primary alcohol use at admission (M=10.5, SD=10.1) were reduced at discharge (M=to 1.2, SD=4.6). At the first follow-up, 79.8% reported no alcohol use and 77.8% reported no alcohol use at the second follow-up. The expected side effects were reported but the medication was well tolerated and there was no relationship between side effects and subsequent dose. Unexamined or unaccounted for variables (e.g., motivation, external pressures to remain in treatment) are "real world" consequences that may have impacted the outcome of this study. Results indicated that use of the antagonist medication XR-NTX may be related to significant decreases in alcohol craving and use while a patient is in treatment, as well as at 30- and 60-days after the final dose.

Gender differences in treatment and clinical characteristics among patients receiving extended release naltrexone.

Further research is needed to investigate real-world acceptability of extended-release naltrexone for alcohol and opioid use disorders, and potential gender differences. This study examines treatment and clinical characteristics among men and women receiving extended-release naltrexone in a large, publicly funded substance use disorder treatment system (N = 465; 52% female). Patient demographics, treatment characteristics, and the number of extended-release naltrexone doses received were collected from administrative data and treatment program staff. Additionally, patients provided information on experiences with extended-release naltrexone in an open-ended format at 1, 2, and 3 weeks following their first injection. For a subsample of patients (N = 220), alcohol/opioid cravings and specific adverse effects were also assessed. Compared to men, women reported experiencing a higher rate and mean number of adverse effects. Overall, craving scores showed substantial reductions over time. However, among patients taking extended-release naltrexone for alcohol use, women showed a significantly greater reduction in craving scores compared to men. No gender differences were observed in the number of extended-release naltrexone doses received. Although women may have a greater need for additional support in managing early adverse effects, extended-release naltrexone as an adjunct to psychosocial treatment may be an acceptable and promising treatment approach for both men and women, and particularly for women prescribed extended-release naltrexone for alcohol use. This study contributes further information on patients' experiences during the early course of extended-release naltrexone treatment in real-world settings. Understanding these experiences may assist policy makers and treatment providers in addressing challenges of implementing this treatment into wider practice.

Predictors of Continued Use of Extended-Released Naltrexone (XR-NTX) for Opioid-Dependence: An Analysis of Heroin and Non-Heroin Opioid Users in Los Angeles County.

Extended-release naltrexone (XR-NTX) is associated with an increased number of opioid-free days, improved adherence rates in substance use disorder treatment programs, and reduced cravings and drug-seeking behaviors. There is little evidence on the predictive associations between baseline characteristics of opioid-dependent patients and XR-NTX utilization. Some studies have demonstrated better pharmacotherapy adherence and/or retention rates among non-heroin opioid users compared to heroin users. This study examines predictive associations between characteristics of patients and XR-NTX utilization, as well as participants' urge to use opiates. Our findings suggest that XR-NTX may contribute to decreases in urges to use among both heroin and non-heroin opioid users. Non-heroin opioid users and heroin users were retained in XR-NTX treatment for comparable periods of time. However, those who identified as homeless, injected opioids (regardless of opioid-type), or were diagnosed with a mental illness were less likely to be retained in treatment with XR-NTX.

A demonstration project implementing extended-release naltrexone in Los Angeles County.

BACKGROUND: Extended-released naltrexone (XR-NTX) is a Food and Drug Administration (FDA)-approved medication associated with higher rates of abstinence, reduced cravings, and delayed relapse to use. However, there is a dearth of literature on real-world implementation of XR-NTX. The Los Angeles County Department of Public Health, in collaboration with UCLA Integrated Substance Abuse Programs, developed a demonstration project to increase access to XR-NTX. This article describes that project, along with data on the expansion of XR-NTX service delivery and patient uptake. METHODS: A secondary descriptive data analysis of demographics, substance use history, current substance use behaviors, health-related variables, and dosing records was conducted on 609 patients who received XR-NTX from Los Angeles County substance use disorder (SUD) treatment facilities from April 2010 through July 2013. A geographic information system approach mapped the distribution of XR-NTX-referring agencies across Los Angeles County. RESULTS: Of the 609 records analyzed, a majority of patients (64%) obtained more than 1 dose of XR-NTX. Most XR-NTX patients reported alcohol use disorder (71.9%; n = 438). Compared with the general Los Angeles County substance use disorder patients, XR-NTX recipients reported more severe substance use histories. Finally, XR-NTX was accessed by providers in 6 of the 8 Service Planning Areas of Los Angeles County. CONCLUSIONS: These findings reflect a higher XR-NTX cessation rate and a lower average number of doses, in contrast to similar demonstration projects in community settings with patients on parole or probation. However, this study shows that it is feasible to engage treatment providers in the use XR-NTX among their patients with alcohol or opioid use disorders. Several implications for future research and implementation are discussed.

Dual Diagnosis Capability in Mental Health and Substance Use Disorder Treatment Programs.

OBJECTIVE: Improved understanding of the relative strengths and weaknesses of treatment organizations' dual diagnosis capability is critical in order to guide efforts to improve services. This study assesses programs' capacity to meet the needs of clients with dual diagnosis, identifies areas where they are well equipped to serve these clients, and determines where programmatic improvement is needed. The study also undertakes an initial exploration of the potential impact that funding sources have on dual diagnosis capability. METHODS: We administered Dual Diagnosis Capability in Addiction Treatment (DDCAT) and Dual Diagnosis Capability in Mental Health Treatment (DDCMHT) assessments at 30 treatment programs in two California counties. Seven of the programs received funding to provide both mental health and substance use disorder services, 13 received funding to provide mental health services, and 10 received funding to provide substance use disorder services. RESULTS: The mean DDCAT/DDCMHT score of programs in the sample was 2.83, and just over 43% of the sample met or exceeded DDCAT/DDCMHT criteria for dual diagnosis capability. Programs scored highest and had the highest rates of dual diagnosis capability in domains related to assessment, training, and staffing, whereas scores were weakest and rates of dual diagnosis capability were lowest in the program structure, treatment, and continuity of care domains. Programs that received funding to provide both mental health and substance use disorder services consistently scored higher than the other programs in the sample, and mental health programs scored higher than substance use disorder treatment programs both on the overall assessments and in most domains. CONCLUSIONS: Findings suggest that programs in the sample are functioning at a nearly dual diagnosis capable level. However, structural barriers continue to limit providers' capacity to serve clients with co-occurring mental health and substance use disorders, and many organizations have not yet translated their potential to deliver dual diagnosis capable services into practice. By enhancing their program structure, treatment services, and continuity of care services, these treatment organizations should be able to deliver fully dual diagnosis capable services. Observed differences in dual diagnosis capability based on funding source indicate a need for further research to better understand the impact that funding streams have on dual diagnosis capability.

Determinants of successful treatment outcomes among a sample of urban American Indians/Alaska Natives: the role of social environments.

Very few studies have analyzed the role of social environments on substance abuse treatment outcomes among urban American Indians/Alaska Natives (AI/ANs). This study examined a measure of positive treatment response-abstinence from substance use at treatment discharge-among urban AI/ANs in Los Angeles County. The sample included all AI/ANs in outpatient drug-free (e.g., no methadone) treatment and residential treatment from 2004 to 2008 (N = 811). Predictors of abstinence at discharge were (a) having recovery-oriented social support and (b) not having a difficult living situation (i.e., experiencing family conflict and/or living with someone who uses alcohol and/or drugs). Higher levels of recovery-oriented social support in the past 30 days predicted abstinence during outpatient treatment. In residential treatment, retention of 90 days or more, high recovery-oriented social support, and not experiencing difficult living situations predicted abstinence. Suggestions for optimizing treatment outcomes among AI/ANs and areas of further research are provided.

Perceptions of mental health and substance use disorder services integration among the workforce in primary care settings.

It is important to understand the perceptions of staff members who will be implementing the expected integration of mental health and substance use services into primary care. Surveys were administered to mental health/substance use disorder (MH/SUD) staff, support staff (SS), and primary care providers (PCPs) from three organizations (seven sites) that were participating in an initiative to promote the integration of MH/SUD services into primary care in Kern County, California. Results suggest that integration and MH/SUD services are highly valued among all staff types, and that staff are uniformly interested in further MH/SUD training. However, there were significant differences in staff perceptions. MH/SUD staff and services were valued by PCPs more than MH/SUD staff perceived being valued by PCPs, and MH/SUD staff were less likely to agree that communication with PCPs was good. Information seemed to flow better from MH/SUD staff to PCPs than in the other direction.

Integrating substance use disorder services with primary care: the experience in California.

Integrating substance use disorder (SUD) services with primary care (PC) can improve access to SUD services for the 20.9 million Americans who need SUD treatment but do not receive it, and help prevent the onset of SUDs among the 68 million Americans who use psychoactive substances in a risky manner. We lay out the reasons for integrating SUD and PC services and then explore the models used and the experiences of providers as they have begun SUD/PC integration in California.

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.

"I've been NIATxed": participants' experience with process improvement.

Process improvement strategies provide industries with a method for improving outcomes and performance at a low cost and with minimal training. In Los Angeles County, two process improvement projects were implemented as a way to improve access to, and engagement and retention in, alcohol and other drug abuse treatment. A qualitative evaluation was completed after the Phase II pilot project to assess how the providers felt about the project, what worked, what did not work, what was learned, and the degree to which process improvements changed program operations. Semistructured interviews were conducted with 33 individuals, representing every level of staff participation in the project. Overall, comments indicated a positive experience for staff, administrators, and clients. Providers noted the relative ease of implementation and how quickly changes resulted in impressive improvements. Challenging issues included resistant staff or a lack of additional resources to pay for the project; however, most noted that these issues were resolved. Interview participants also requested more training on data collection and a reduction in the frequency of the project conference calls. This study gives support to the idea of process improvement being a tool that dramatically improves services to consumers of addiction treatment services.

Inside the black box: measuring addiction treatment services and their relation to outcomes.

The adoption of performance-based management has been under consideration by addiction treatment funding agencies, and, recently, many state and county agencies have developed performance-based measurement/management systems in an attempt to improve their treatment system. This article describes one such effort in Los Angeles County, California. The Performance-Based Pilot Project linked treatment encounters (counseling sessions, drug testing, case management, and methadone dosing) with client outcomes (abstinence or reduced drug use at discharge) and longer lengths of stay in treatment. Eleven outpatient counseling programs and three narcotic treatment programs participated in the nine-month project. Results indicated that for both outpatient counseling and narcotic treatment programs, more sessions attended in the first 30 days was associated with better client outcomes and longer lengths of stay. Furthermore, in outpatient counseling programs, more group sessions during the first 30 days predicted abstinence or greater reductions in primary drug use; in narcotic treatment programs, more doses received during the first 30 days was correlated to longer treatment retention. This research implies that increasing the availability of counseling sessions for a client's first 30 days and engaging clients early is a promising area for program efforts to improve treatment outcomes and program performance.

Improving client engagement and retention in treatment: the Los Angeles County experience.

This article discusses a two-phase demonstration project focused on the implementation of the Network for the Improvement of Addiction Treatment model of process improvement among substance abuse treatment providers in Los Angeles County, California. A total of 30 Change Teams from 12 county-contracted treatment agencies planned and executed one or more rapid-cycle change projects to reduce wait time to treatment, reduce no-shows to scheduled appointments, increase admissions, or improve continuation in treatment. The findings and lessons learned illustrate the importance of a concrete and straightforward methodology and consistent peer-to-peer interaction provided in a learning collaborative environment. In addition, both ongoing technical assistance and coaching are essential for successful implementation of this innovative, low-cost, evidence-based process improvement strategy.
