RESUMEN
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.

This study provides preliminary evidence of the effectiveness of the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) and ASSIST-linked brief intervention in a college mental health clinic. Data are from a single group, pre-post evaluation study (2006-2009) at a university counseling center. Students deemed to be at risk for substance use problems were offered the ASSIST and the ASSIST-linked brief intervention. Staff therapists administered the ASSIST and intervention as part of routine care; 453 students (ages 18-24) participated in the evaluation and completed baseline and six-month follow-up interviews. Changes in alcohol and marijuana use were examined by McNemar's test of proportions and by paired t-tests for means. Slight reductions in the rates and number of days (in the prior 30 days) of binge drinking and marijuana use were found. Routine screening and brief intervention procedures in a mental health setting may reduce problematic substance use among college students.

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.

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.
