A Randomized Trial of a Hepatitis Care Coordination Model in Methadone Maintenance Treatment

OBJECTIVES We evaluated the efficacy of a hepatitis care coordination intervention to improve linkage to hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination and clinical evaluation of hepatitis C virus (HCV) infection among methadone maintenance patients. METHODS We conducted a randomized controlled trial of 489 participants from methadone maintenance treatment programs in San Francisco, California, and New York City from February 2008 through June 2011. We randomized participants to a control arm (n = 245) and an intervention arm (n = 244), which included on-site screening, motivational-enhanced education and counseling, on-site vaccination, and case management services. RESULTS Compared with the control group, intervention group participants were significantly more likely (odds ratio [OR] = 41.8; 95% confidence interval [CI] = 19.4, 90.0) to receive their first vaccine dose within 30 days and to receive an HCV evaluation within 6 months (OR = 4.10; 95% CI = 2.35, 7.17). A combined intervention adherence outcome that measured adherence to HAV-HBV vaccination, HCV evaluation, or both strongly favored the intervention group (OR = 8.70; 95% CI = 5.56, 13.61). CONCLUSIONS Hepatitis care coordination was efficacious in increasing adherence to HAV-HBV vaccination and HCV clinical evaluation among methadone patients.

Anger Management Group Treatment for Cocaine Dependence: Preliminary Outcomes

Cocaine abusers who fail to manage anger appropriately may have greater difficulty achieving and maintaining abstinence. We conducted a pilot study to examine an anger management group treatment in a sample of 59 men and 32 women with a diagnosis of cocaine dependence. Participants attended a 12-week anger management group treatment and background substance abuse treatment. Levels of anger, negative affect, and anger control were measured at baseline, weekly during treatment, and at 3-month posttreatment follow-up. Levels of anger decreased and anger control increased between baseline and the end of treatment. End-of-treatment changes were maintained at follow-up. These findings were not moderated by gender, age, or psychiatric medication use. In the absence of a randomized control group, we cannot make conclusive statements regarding the effectiveness of the anger management group treatment. However, these preliminary findings demonstrate the need for a randomized clinical trial to test the efficacy of the anger management group treatment.

Self-Efficacy and Illicit Opioid Use in a 180-Day Methadone Detoxification Treatment.

Self-efficacy ratings coincided with illicit opioid use across the 3 phases of a 180-day methadone detoxification treatment. Efficacy ratings increased after patients received their first dose of methadone, did not change while they were maintained on a stable dose of methadone, and declined during the taper as they attempted to face high-risk situations without the full benefit of methadone. Efficacy ratings measured at a point before a phase of treatment predicted illicit opioid use across that phase. For clarification of the relation between self-efficacy and illicit opioid use, 3 conceptual models proposed by J.S. Baer, C.S. Holt, and E. Lichtenstein (1986) were tested. Self-efficacy influenced subsequent drug use in parallel with previous behavior, but this influence was found only at the start of the stabilization phase and immediately before the start of the taper phase. These findings highlight the usefulness of the self-efficacy concept for the treatment of opioid addiction.

Anger Management and Temper Control: Critical Components of Posttraumatic Stress Disorder and Substance Abuse Treatment

Recent studies have shown associations among combat experience, PTSD, anger and hostility, and involvement in violence. Clinical observations of veterans enrolled in the Substance Use/Posttraumatic Stress Disorder Team (SUPT) program at the San Francisco Veterans Affairs Medical Center revealed relatively high levels of anger and aggressive behavior, including physical assaults and property damage. In response to this anger and aggressive behavior, an anger management treatment was added to the SUPT programs treatment of substance abuse and PTSD. Anger management consisted of a 12-week cognitive-behavioral group treatment. Session topics included identifying the physical, emotional, and situational cues to anger, developing individualized anger-control plans, recognizing and altering destructive self-talk, utilizing time-out, practicing conflict resolution techniques, and using the group to discuss and evaluate high-risk anger situations. Special attention was given to self-monitoring anger-escalating behavior (using an anger meter) and avoiding negative consequences. This article describes the components of the anger management treatment. A clinical vignette is also presented to illustrate the benefits of anger management treatment.

Possible barriers to enrollment in substance abuse treatment among a diverse sample of Asian Americans and Pacific Islanders: Opinions of treatment clients

This mixed methods study examined motivations and barriers to substance abuse treatment entry and treatment continuation among Asian American and Pacific Islander (AAPI) substance users. AAPI substance users (N = 61) were recruited from substance abuse treatment programs in California and Hawaii. Semi-structured interviews and interviewer-administered surveys assessed barriers and facilitators to entering substance abuse treatment. Barriers included peer pressure, family influences, and face loss concerns. Facilitators included peer support, involvement in the criminal justice system, a perceived need for treatment, and culturally competent substance abuse treatment services. Family and peer influences may act as both facilitators and impediments. AAPI substance using populations face many of the same individual-level and structural and systems barriers to entry to treatment as other substance using populations. However, similar to other racial/ethnic minority groups, it is important to address cultural differences and develop culturally competent substance abuse treatments for the AAPI population.

Methadone patients in the therapeutic community: a test of equivalency.

BACKGROUND Residential therapeutic communities (TCs) have demonstrated effectiveness, yet for the most part they adhere to a drug-free ideology that is incompatible with the use of methadone. This study used equivalency testing to explore the consequences of admitting opioid-dependent clients currently on methadone maintenance treatment (MMT) into a TC. METHODS The study compared 24-month outcomes between 125 MMT patients and 106 opioid-dependent drug-free clients with similar psychiatric history, criminal justice pressure and expected length of stay who were all enrolled in a TC. Statistical equivalence was expected between groups on retention in the TC and illicit opioid use. Secondary hypotheses posited statistical equivalence in the use of stimulants, benzodiazepines, and alcohol, as well as in HIV risk behaviors. RESULTS Mean number of days in treatment was statistically equivalent for the two groups (166.5 for the MMT group and 180.2 for the comparison group). At each assessment, the proportion of the MMT group testing positive for illicit opioids was indistinguishable from the proportion in the comparison group. The equivalence found for illicit opioid use was also found for stimulant and alcohol use. The groups were statistically equivalent for benzodiazepine use at all assessments except at 24 months where 7% of the MMT group and none in the comparison group tested positive. Regarding injection- and sex-risk behaviors the groups were equivalent at all observation points. CONCLUSIONS Methadone patients fared as well as other opioid users in TC treatment. These findings provide additional evidence that TCs can be successfully modified to accommodate MMT patients.

The angry patient: an intervention for managing anger in substance abuse treatment

Patients who have problems controlling anger and aggression can pose special problems for substance abuse treatment providers. Levels of anger and violence are higher in substance abusers than in the general population. Although anger management treatments have been studied extensively, few treatments have been developed and studied with substance abusers. In this article, we evaluated an anger management treatment based on Novacos (1983) cognitive-behavioral stress inoculation procedures. The treatment was delivered as individual sessions and evaluated in a study of six substance abuse patients with a single-subject multiple-baseline design. Preliminary findings suggest that the treatment is effective for substance abuse patients and that this mode of treatment should be explored further.

Methadone transition treatment: a treatment model for 180-day methadone detoxification.

For those drug addicts who do not meet the United States federal government regulations for methadone maintenance, methadone detoxification remains the primary option for treatment. Studies on the effectiveness of 21-day methadone detoxification, however, report low completion rates and high relapse. Revisions to the standard 21-day detoxification are needed. The research literature suggests that offering psychosocial services within an extended 180-day protocol may be an effective mode of treatment for those addicts who do not meet the requirements for entering methadone maintenance, or do not desire maintenance. Methadone Transition Treatment (MTT) is an innovative treatment organized around this strategy. MTT is transitional in that emphasis is place on working with patients to enter longer-term treatment. To aid the development of similar programs at other institutions, we describe the specific procedures of the MTT model and provide an evaluation of the model based on findings from an initial pilot study.

Scientific Writing Seminar for Early-stage Investigators in Substance Abuse Research

BACKGROUND There is little information on how to increase the scientific writing productivity of early-stage investigators in the addictions field. A scientific writing seminar is presented in this article, aiming to encourage manuscript writing and dissemination of addiction research, and outcomes are reported for 14 years of the seminar. METHODS In 14 years, there were 113 postdoctoral fellow enrollments in a 6-month writing seminar. Records of submission and publication rates of manuscripts were collected for 14 cohorts. RESULTS Of the 113 participant enrollments, 97 (86%) submitted a manuscript for publication, and 87 participants (77%) published their manuscript. CONCLUSIONS A scientific writing seminar may benefit writing productivity, but more research is needed to compare this training model with other existing models.

Education and counseling in the methadone treatment setting improves knowledge of viral hepatitis

The aim of this study was to evaluate the effectiveness of an educational method of providing viral hepatitis education for methadone maintenance patients. Four hundred forty participants were randomly assigned to either a control or a motivationally-enhanced viral hepatitis education and counseling intervention. Viral hepatitis A (HAV), B (HBV), and C (HCV) knowledge tests were administered at baseline, following each of two education sessions (post-education), and at a 3-month follow-up assessment. Results indicated a significant increase in knowledge of HAV, HBV, and HCV over time. No differences were found in knowledge between the intervention groups in knowledge acquisition regarding any of the hepatitis viruses suggesting that a motivational interviewing style may not augment hepatitis knowledge beyond standard counseling. A two-session viral hepatitis education intervention effectively promotes hepatitis knowledge and can be integrated in methadone treatment settings.
