Primary heroin users + drug-free treatment: an equation for success?

Buprenorphine from detox and beyond: preliminary evaluation of a pilot program to increase heroin dependent individuals' engagement in a full continuum of care

Absence of successful transition to post-detoxification treatment leads to high rates of relapse among detoxified heroin users. The present study evaluated a pilot buprenorphine treatment program (BTP). Heroin dependent individuals were inducted onto buprenorphine/naloxone in detox, maintained while transitioning through an intensive inpatient program (IIP), and gradually tapered off medication over 5 months of outpatient (OP) treatment. Compared to programmatic indicators of treatment engagement in the year prior to BTP implementation, referrals from detox to IIP, entry into and completion of IIP and subsequent OP, and days in OP treatment increased substantially. BTP completers, compared to non-completers, viewed abstinence as more difficult and as requiring more assistance to achieve, were less likely to be current cocaine and alcohol users or to have relapsed during the course of treatment. Although preliminary and in need of replication, initial adjunctive use of buprenorphine in an abstinence-based continuum of care may improve post-detoxification treatment entry, engagement, and completion.

Abstinence-orientated residential rehabilitation of opioid users in Denmark: do changes in national treatment policies affect treatment outcome?

AIMS

Significant changes in the Danish drug-abuse treatment system occurred from 1998 to 2008, allowing the opportunity to study their impact on outcomes for opiate dependent patients. This paper examines whether such changes are related to possible changes in abstinence rates of two cohorts of drug users.

METHODS

We compared survival curves and the month-by-month probability of abstinence between cohorts of drug abusers who were followed for one year after treatment for opioid dependence in 1998 (n = 305) and in 2008 (n = 204). Of the 1998 cohort, 192 were interviewed face-to-face and 61 were found through national drug-abuse treatment registers. Of the 2008 cohort 112 were interviewed face-to-face and 42 were found through national drug-abuse treatment registers.

RESULTS

Survival curves did not differ between the two cohorts. After controlling for age and gender, people from the 2008 cohort had a higher frequency of month-to-month rates of abstinence. A higher proportion of clients received new treatment after their index treatment in 2008. Clients from the 1998 cohort who did not receive new treatment used drugs more often than clients who did not receive treatment in 2008. At the same time, the proportion of clients who received residential rehabilitation treatment for opiate dependence increased substantially by 2008.

CONCLUSIONS

Total abstinence rates are highly consistent over time and seem to change little with changes in systems of care. However, changes in care that improve access to treatment may reduce the overall burden of opioid addiction to both individuals and society.

Differentiating LGBT individuals in substance abuse treatment: analyses based on sexuality and drug preference

In a prior study (Cochran & Cauce, 2006), LGBT individuals seeking treatment demonstrated greater substance use severity, more psychosocial stressors, and increased use of psychiatric services when compared to their heterosexual counterparts. That study, and similar to others in the field of LGBT research, collapsed LGBT individuals into a single category and did not examine individual differences within this category. The present study utilizes the same sample of LGBT clients (N = 610); however, an exploratory cluster analysis was conducted, based on drug preference, to determine which subcategories exist within this unique sample. In a subsequent set of analyses, the sample was divided based on sexuality to determine if there were differences between these groups on psychosocial functioning variables. Results indicated three distinct clusters, which differed in both demographic characteristics and severity of substance use problems. Groups based on sexuality differed in terms of primary problem substance, as well as psychosocial variables. Implications for treatment of these subgroups are discussed.

Evidence-based treatment for opiate-dependent clients: availability, variation, and organizational correlates

The majority of opiate-dependent clients entering substance abuse treatment are referred to "drug-free" (non-methadone) modalities. Given the known challenges of treating these clients in drug-free settings relative to the documented effectiveness of methadone maintenance, these analyses investigate the availability of various clinical and wraparound services for this population among a US sample of addiction treatment programs with and without methadone maintenance services (N = 763). Face-to-face interviews conducted in 2002-2003 gathered data on the number of opiate-dependent clients treated; organizational characteristics, including size, ownership, accreditation, and staffing; treatment practices, including methadone availability, use of other pharmacotherapies, and levels of care; and services offered, including vouchers, transportation, and other wraparound services. Facilities treating proportionately more opiate-dependent clients were significantly more likely to offer a variety of evidence-based services, regardless of methadone availability. Implications for referral linkages and quality of care are discussed.

Challenges in motivating treatment enrollment in community syringe exchange participants

Participants of syringe exchange programs (SEPs) exhibit high rates of substance use disorder but remain extremely ambivalent about seeking treatment. This study evaluated the effectiveness of motivational interviewing (MI) for encouraging SEP participants to enroll in substance abuse treatment. New opioid-dependent registrants to the Baltimore Needle Exchange Program (BNEP) (n =302) completed the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV), and the Addiction Severity Index (ASI) and were randomly assigned to one of three treatment referral conditions: (1) MI, (2) job readiness (JR) (attention control), or (3) standard referral. Participants in each condition who expressed interest in treatment were referred to a treatment readiness group that provided further encouragement and referral to programs that were accepting new admissions. Participants were observed for 1 year following the intervention. The results showed that 10.9% of study participants enrolled in substance abuse treatment, although no condition effects were observed. White participants and those diagnosed with major depression were most likely to enter treatment. The results suggest that a single motivational interview is insufficient to motivate changes in treatment seeking in this population, whereas the identification of predictors of treatment enrollment is worthy of further investigation.

Gender, waitlists, and outcomes for public-sector drug treatment

This study evaluated gender differences in baseline characteristics and treatment outcomes among 654 treatment seekers referred to state-funded drug treatment. Women were significantly less likely than men to enter treatment following referral, but not significantly less likely to complete treatment, once they entered. After adjustment for treatment dose, gender differences in substance use at followup (3-6 months after leaving the treatment wait list) were nonsignificant. The genders did not differ significantly in rates of psychosocial improvement between referral and followup. Women waited significantly longer than men before leaving the treatment wait list (with or without treatment entry), but wait time was associated with entry rates only among men. The authors discuss system-level and personal characteristics that potentially affect wait times and call for additional study of whether abbreviating waits can increase women's treatment entry rates.
