Correlates of drug injection behaviors among methadone outpatients

Comorbilidad entre distrés psicológico y abuso de drogas en pacientes de centros de tratamiento: implicaciones en políticas y programas, Managua - Nicaragua

El objetivo de este estudio fue determinar la prevalencia de la comorbilidad entre el distress psicológico y el abuso/dependencia de drogas en los pacientes de los centros de tratamiento de Nicaragua. Se aplicaron cuestionarios EULAC-CICAD en forma de entrevista para describir el perfil del paciente y Kessler 10 para estimar niveles del distress a 130 usuarios de tres Centros de las Organizaciones no Gubernamentales de Managua, Nicaragua. Nivel encontrado de distress psicológico (severo y muy severo), fue de un 35%. También se encontró que un número importante de los pacientes que están siendo tratados actualmente por problemas de salud mental, persisten en experimentar síntomas del distress psicológico. Se concluyó que los hallazgos de este estudio sugieren una revisión sistemática de las políticas y estrategias de intervención y el fortalecimiento de ambos sistemas involucrados, Sistema de Salud y de Drogodependencia.

Psychiatric, behavioural and social risk factors for HIV infection among female drug users

Female drug users report greater psychopathology and risk behaviours than male drug users, putting them at greater risk for HIV. This mixed-methods study determined psychiatric, behavioural and social risk factors for HIV among 118 female drug users (27% (32/118) were HIV seropositive) in Barcelona. DSM-IV disorders were assessed using the Spanish Psychiatric Research Interview for Substance and Mental Disorders. 30 participants were interviewed in-depth. In stepwise multiple backward logistic regression, ever injected with a used syringe, antisocial personality disorder, had an HIV seropositive sexual partner and substance-induced major depressive disorder were associated with HIV seropositivity. Qualitative findings illustrate the complex ways in which psychiatric disorders and male drug-using partners interact with these risk factors. Interventions should address all aspects of female drug users' lives to reduce HIV.

Oral substitution treatment of injecting opioid users for prevention of HIV infection

BACKGROUND

Injecting drug users are vulnerable to infection with Human Immunodeficiency Virus (HIV) and other blood borne viruses as a result of collective use of injecting equipment as well as sexual behaviour

OBJECTIVES

To assess the effect of oral substitution treatment for opioid dependent injecting drug users on risk behaviours and rates of HIV infections

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and PsycINFO to May 2011. We also searched reference lists of articles, reviews and conference abstracts

SELECTION CRITERIA

Studies were required to consider the incidence of risk behaviours, or the incidence of HIV infection related to substitution treatment of opioid dependence. All types of original studies were considered. Two authors independently assessed each study for inclusion

DATA COLLECTION AND ANALYSIS

Two authors independently extracted key information from each of the included studies. Any differences were resolved by discussion or by referral to a third author.

MAIN RESULTS

Thirty-eight studies, involving some 12,400 participants, were included. The majority were descriptive studies, or randomisation processes did not relate to the data extracted, and most studies were judged to be at high risk of bias. Studies consistently show that oral substitution treatment for opioid-dependent injecting drug users with methadone or buprenorphine is associated with statistically significant reductions in illicit opioid use, injecting use and sharing of injecting equipment. It is also associated with reductions in the proportion of injecting drug users reporting multiple sex partners or exchanges of sex for drugs or money, but has little effect on condom use. It appears that the reductions in risk behaviours related to drug use do translate into reductions in cases of HIV infection. However, because of the high risk of bias and variability in several aspects of the studies, combined totals were not calculated.

AUTHORS' CONCLUSIONS

Oral substitution treatment for injecting opioid users reduces drug-related behaviours with a high risk of HIV transmission, but has less effect on sex-related risk behaviours. The lack of data from randomised controlled studies limits the strength of the evidence presented in this review.

Depressive symptoms, substance use, and HIV-related high-risk behaviors among opioid-dependent individuals: results from the Clinical Trials Network

The sample included 343 opioid-dependent adults enrolled in two national multisite studies of the National Drug Abuse Treatment Clinical Trials Network (CTN001-002). Opioid-dependent individuals were recruited from 12 sites across the United States from January 2001 to July 2002. We examined associations between depressive symptoms, co-occurring substance use (i.e., the use of substances other than opioids), and HIV-related sexual and injection risk behaviors. Data were collected using the Addiction Severity Index and the HIV Risk Behavior Scale, and analyzed using linear regression. Depressive symptoms were associated with an increased level of injection risk behaviors but were not associated with risky sexual behaviors. The co-occurring use of amphetamines also increased the likelihood of risky sexual behaviors. The study limitations and clinical implications are noted. The study was funded by the U.S. National Institute on Drug Abuse.

OBJECTIVES

To assess the effect of oral substitution treatment for opioid dependent injecting drug users on rates of HIV infections, and high risk behaviours.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and PsycINFO to March 2007. We also searched reference lists of articles, reviews and conference abstracts

SELECTION CRITERIA

Studies were required to consider the incidence of risk behaviours, or the incidence of HIV infection related to substitution treatment of opioid dependence. All types of original studies were considered. Two reviewers independently assessed studies for inclusion.

DATA COLLECTION AND ANALYSIS

One reviewer extracted data from included studies, assessed quality and confirmed decisions by consulting with all other reviewers.

Meta-analysis of depression and substance use and impairment among intravenous drug users (IDUs)

AIMS

To evaluate, among intravenous drug users (IDUs), the hypothesized positive association of depression with substance-related behaviors including concurrent drug use and impairment, future drug use and impairment, alcohol use and impairment, needle sharing and substance use treatment participation, and to identify moderators of these associations.

DESIGN

Meta-analysis of reports on IDUs published in English in peer-reviewed journals since 1986 that contained data on depression and substance use outcome(s) with no restrictions on range of depression scores to select the sample.

SETTING

Fifty-five reports containing 55 samples met criteria, including 42 (76%) samples from clinical venues and 13 (24%) that were community-based.

PARTICIPANTS

Mean age was 34.3 (standard deviation = 4.5) years, comprising approximately 68% men and 43% white, non-Hispanic subjects.

MEASUREMENTS

Depression was assessed with the Beck Depression Inventory, Center for Epidemiological Studies Depression Scale (CES-D) and other validated scales or diagnostic interviews. The Addiction Severity Index was the most frequently used measure of substance-related outcomes.

FINDINGS

A priori hypotheses pertaining to depression and the substance-related variables were supported, with the exception of the predicted association of depression and future drug use and impairment. Effect sizes were small. Moderating effects of gender were identified, including greater associations of depression with substance use treatment participation and needle sharing among women and a greater association of depression with future drug use and impairment among men. Effect sizes of moderators were large.

CONCLUSIONS

Depression is associated with several substance-related behaviors, and select associations are stronger according to gender. Prospective associations of depression with future drug use and impairment are not immediately evident, but could be examined in subsequent research.

The dynamics of injection drug users' personal networks and HIV risk behaviors

AIMS

While studies of the social networks of injection drug users (IDUs) have provided insight into how the structures of interpersonal relationships among IDUs affect HIV risk behaviors, the majority of these studies have been cross-sectional. The present study examined the dynamics of IDUs' social networks and HIV risk behaviors over time.

DESIGN

Using data from a longitudinal HIV-intervention study conducted in Baltimore, MD, this study assessed changes in the composition of the personal networks of 409 IDUs. We used a multi-nomial logistic regression analysis to assess the association between changes in network composition and simultaneous changes in levels of injection HIV risk behaviors. Using the regression parameters generated by the multi-nomial model, we estimated the predicted probability of being in each of four HIV risk behavior change groups.

FINDINGS

Compared to the base case, individuals who reported an entirely new set of drug-using network contacts at follow-up were more than three times as likely to be in the increasing risk group. In contrast, reporting all new non-drug-using contacts at follow-up increased the likelihood of being in the stable low-risk group by almost 50% and decreased the probability of being in the consistently high-risk group by more than 70%.

CONCLUSIONS

The findings from this study show that, over and above IDUs' baseline characteristics, changes in their personal networks are associated with changes in individuals' risky injection behaviors. They also suggest that interventions aimed at reducing HIV risk among IDUs might benefit from increasing IDUs' social contacts with individuals who are not drug users.

Reductions in HIV risk behaviors among depressed drug injectors

OBJECTIVE

To determine if, by reducing depressive symptoms, combined psychotherapy and pharmacotherapy reduces HIV drug risk behavior compared to an assessment-only condition for active drug injectors over 9 months.

DESIGN

Randomized controlled trial.

SETTING

Outpatient academic research office.

PATIENTS

Active injection drug users with a DSM-IV diagnosis of major depression, dysthymia, substance-induced mood disorder with depressive features persisting for at least 3 months, or major depression plus dysthymia. In addition, participants had a Hamilton Rating Scale for Depression (MHRSD) score > 13.

INTERVENTION

Psychotherapy (8 sessions of cognitive behavioral therapy) plus antidepressant pharmacotherapy over 3 months.

MAIN OUTCOME MEASURES

HIV Risk Assessment Battery (RAB) drug scale scores measured at three, six and nine months, and depression remission (MHRSD score < or = 8).

RESULTS

Participants (n= 109) were 64% male, 82% Caucasian, with a mean baseline MHRSD score of 20.7. Depression subtypes included major depression only (63%), substance-induced depression (17%), and double-depression (17%). Overall, study retention at nine months was 89%. Reported HIV drug risk scores decreased sharply over the first 3 months and continued to decline throughout the follow-up period. Between group differences were not significant in the intention-to-treat analysis. However, highly adherent participants had significantly lower HIV drug risk scores at 3 months (p<05), but not 6 and 9 months. Depression remission was significantly associated with lower HIV drug risk scores at follow-ups.

CONCLUSIONS

Combined psychotherapy and pharmacotherapy did not produce a significant reduction in HIV drug risk beyond that seen in an assessment-only control group. The greatest declines in HIV drug risk were found in participants with high protocol adherence and those with depression remission.

Substitution treatment of injecting opioid users for prevention of HIV infection

BACKGROUND

Injecting drug users are vulnerable to infection with HIV and other blood borne viruses as a result of collective use of injecting equipment as well as sexual behaviour.

OBJECTIVES

To assess the effect of oral substitution treatment for opioid dependent injecting drug users on rates of HIV infections, and high risk behaviours.

SEARCH STRATEGY

Multiple electronic databases were searched. Reference lists of retrieved studies, reviews and conference abstracts were handsearched.

SELECTION CRITERIA

Studies were required to consider the incidence of risk behaviours, or the incidence of HIV infection related to substitution treatment of opioid dependence. All types of original studies were considered.

DATA COLLECTION AND ANALYSIS

Each potentially relevant study was independently assessed by two reviewers. For studies that met the inclusion criteria, key information was extracted by one reviewer and confirmed by consultation between all four reviewers.

MAIN RESULTS

Twenty-eight studies, involving 7900 participants, were included. The majority were not randomised controlled studies. Issues of confounding and bias are discussed. The studies varied in several aspects limiting the extent of quantitative analysis.

REVIEWERS' CONCLUSIONS

Oral substitution treatment for opioid-dependent injecting drug users is associated with statistically significant reductions in illicit opioid use, injecting use and sharing of injecting equipment. It is also associated with reductions in the proportion of injecting drug users reporting multiple sex partners or exchanges of sex for drugs or money, but has little effect on condom use. It appears that the reductions in risk behaviours related to drug use do translate into reductions in cases of HIV infection. The lack of data from randomised controlled studies limits the strength of the evidence presented in this review. However, these findings add to the stronger evidence of effectiveness of substitution treatment on drug use, and treatment retention outcomes shown by other systematic reviews. On this basis, the provision of substitution treatment for opioid dependence in countries with emerging HIV and injecting drug use problems as well as in countries with established populations of injecting drug users should be supported.

Relationship between Tridimensional Personality Questionnaire scores and clinic attendance among cocaine abusing, buprenorphine maintained outpatients

With the recent approval of buprenorphine for the treatment of opiate dependence in the United States it has become important to develop an understanding of the factors that influence the likelihood of successful treatment outcomes when using buprenorphine. This study examined, in a convenience sample, the relationship between novelty-seeking behaviors, as determined by Cloninger's Tridimensional Personality Questionnaire (TPQ), and attendance variables during participation in a buprenorphine-based treatment program for 21 heroin-dependent cocaine users that took place in the late 1990s. Approximately two-thirds of the participants were male and primarily African-American. About half of them were employed and had at least a high school education. Approximately one-third of them were married or cohabitating and they all resided in the greater Detroit, Michigan area of the United States. The Tridimensional Personality Questionnaire (TPQ) was administered to the participants prior to entering the treatment program. Demographic variables, psychiatric distress, and substance use severity were also evaluated. Variables with significant bivariate relationships with poor attendance measures were entered into a regression analysis predicting attendance measures. Participants who scored high on the TPQ Novelty Seeking Scale attended significantly fewer regularly scheduled visits, had a greater overall number of missed visits, and shorter treatment retention times. Demographics, substance use severity, and psychiatric distress did not have significant relationships with these attendance measures.

A staging system to predict prognosis among methadone maintenance patients, based on admission characteristics

As U.S. general internists play an increasing role in providing opioid maintenance therapy in practice offices, they are having to face the challenge of identifying patients who need specialized services especially at the outset of treatment. In methadone maintenance treatment, prognostic studies have failed to find robust predictors on the basis of single predictive variables. We hypothesize that a multivariable staging system will predict treatment outcome more accurately than single variables. We reviewed baseline and treatment data regarding 226 consecutive patients admitted to a methadone maintenance program in New Haven, Connecticut, from January 1, 1993 to March 28, 1994, and followed until December 1, 1996. The staging system was developed from the data on the first 112 patients, confirmed in the remaining 114 patients, and then applied to the entire cohort of 226 patients. Retention was the main outcome measure used in developing the staging system. The staging system was also validated as a predictor of illicit drug use during treatment and adverse discharge. In the staging system one point is scored for each of the following: use of more than two bags of heroin daily, previous prison term, previous period in reform school, and a history of diseases related to substance use, e.g., endocarditis, hepatitis, abscesses, and overdose. The total score classifies patients as Stage I (0 and 1 points), Stage II (2 points), or Stage III (3 and 4 points). This staging system was significantly associated with retention in a proportional-hazards model, and no other variable added any additional predictive influence. The specific stage was also found to be a significant predictor of adverse discharge. Although additional validation is necessary in other populations, we found the staging system to be a useful and simple way of identifying patients at risk for early attrition and adverse discharge.

Factors affecting client response to HIV outreach efforts

PURPOSE

This article describes 12 HIV Outreach Demonstration Projects funded by the Center for Substance Abuse Treatment in 1995, and the clients these projects served. The article also summarizes the findings of multivariate statistical analyses aimed at identifying important project and client characteristics that influenced project success in achieving two key outcomes: persuading at-risk clients to obtain HIV tests, and facilitating entry by substance-abusing clients into structured substance abuse treatment (SAT).

METHODS

Hierarchical linear modeling (HLM) analysis was used to conduct the analyses.

RESULTS

The findings support the hypothesis that HIV Outreach, as an integrated approach to addressing the multiple problems clients have due to substance abuse and related problems, can be an effective model for reaching clients who have not been reached through traditional means.

IMPLICATIONS

By implementing a complement of comprehensive HIV Outreach interventions, many of the HIV Outreach projects were successful in addressing the various needs of their clients. However, as detailed in this article, some services and service delivery procedures, were more effective than others in achieving project objectives.

Social relationships and intravenous drug use among methadone maintenance patients

This study examined the extent to which social relationships were associated with continued injection drug use and needle sharing among 252 methadone maintenance patients. Logistic regression analyses indicated that drug use was highest among persons who had a substance using live-in partner and among those with more drug-using social relationships. Among injectors, whites and those who had more people present during IV drug use were more likely to share needles, while those with more emotional support were less likely to do so. These findings suggest that personal relationships strongly influence continued injection drug use and that methadone programs should help patients develop social networks of non-users.

Novelty seeking as a predictor of treatment retention for heroin dependent cocaine users

This study examined the relationship between novelty seeking between treatment retention and among heroin dependent cocaine users. Participants were treated with buprenorphine maintenance and contingency management. The Tridimensional Personality Questionnaire's (TPQ) Novelty Seeking scale was administered to 68 participants prior to buprenorphine induction. Demographics, mood and anxiety disorders, antisocial personality disorder, and substance use were also assessed. Variables with significant relationships with overall retention were entered into a logistic regression analysis. In addition, using a survival analysis, all variables with significant relationships with time to drop-out were entered into a multivariate proportional hazards regression with time dependent covariates. Results demonstrated that although high novelty seekers, in comparison to low novelty seekers, were more likely to drop-out by the end of treatment, they had higher retention rates during the early phases of treatment. It is suggested that buprenorphine and contingency management were viewed by participants as novel treatment components and thus facilitated high novelty seekers' success early in treatment. If replicated, results suggest that inclusion of novel treatment components might facilitate retention among this at-risk group.

Changes in methadone treatment practices: results from a panel study, 1988-1995

Results from several studies conducted in the late 1980s and early 1990s showed that the majority of the nation's methadone treatment units did not use effective treatment practices. Since then, however, many efforts have been made to improve critical treatment practices. This paper examines the extent to which key methadone treatment practices (dose levels, treatment duration, client influence in dose decisions) changed from 1988 to 1995 in a panel sample of methadone maintenance units. We also examine factors that may account for variation in methadone treatment practices. We use panel data from a national random sample of 172 units in 1988 (82% response rate), 140 units in 1990 (87% response rate), and 116 units in 1995 (89% response rate). Unit directors and clinical supervisors provided phone survey data on clients influence on doses, upper limits on doses, average dose levels, unit emphasis on decreasing doses, time when clients are encouraged to detoxify, and average length of treatment. Results from random effects regression analyses indicate that treatment practices concerning methadone dose levels, client influence in dose decisions, and treatment duration improved significantly between 1988 and 1995. Several characteristics of clients (race, age) and treatment units (staff, ownership, geographic location) are associated with the use of less-effective treatment practices. Efforts to improve treatment practices appear to be making progress and certainly need to be continued.

Depressive symptoms, drug network, and their synergistic effect on needle-sharing behavior among street injection drug users

In this study, we examined the relationship between depressive symptoms and needle-sharing behavior in a community sample of intravenous drug users (N = 499) in Baltimore, Maryland. Based on the polytomous logistic regression, higher depressive symptoms were positively associated both with needle sharing after cleaning with bleach and with needle sharing without first cleaning with bleach at the bivariate analyses. This relationship remained significant (OR = 1.66) even after adjusting for demographic characteristics, life events, drug use patterns, and social and drug networks. A significant synergistic effect of depressive symptoms and drug network on needle sharing after cleaning with bleach and needle sharing without cleaning was observed. More depressed intravenous drug users who also had a larger drug network were found to be at higher risk of needle sharing after cleaning with bleach, as well as needle sharing without cleaning (OR = 2.59). Depression status is discussed as a predisposing factor and drug network size as a precipitating factor for needle-sharing behavior. Implications for preventing needle-sharing behavior by reducing depressive symptoms are discussed.

Passages: A Therapeutic Community Oriented Day Treatment Model for Methadone Maintained Clients

Passages is a day treatment model based on therapeutic community (TC) methods adapted for methadone maintained clients. The goal of the program is to reduce cocaine use and injection, other drug use, and high-risk sexual behavior. The Passages approach is grounded in a recovery-oriented perspective in which methadone is a prescribed medicine that can facilitate a self help, recovery process. Preliminary evaluation findings on over 500 research participants indicate greater differential improvement in drug-risk behavior and psychological status for the Passages clients who remained 6 months in the program compared to non-Passages clients. Though awaiting controlled studies, the present study demonstrated the feasibility of integrating methadone maintenance and TC-oriented day treatment in methadone clinics; and provided evidence for the effectiveness of the Passages program in reducing risk behavior and improving psychological functioning among seriously dysfunctional substance abusers.

Predictors of Treatment Retention in Enhanced and Standard Methadone Maintenance Treatment for HIV Risk Reduction

Survival analysis was used to determine the predictors of discharge from a methadone maintenance treatment program for heroin addicts at high-risk for HIV infection and/or transmission. A consistent set of predictors was identified that was associated with treatment discharge at 90 days, 12 months, 18 months, and 24 months. Individuals who, at intake, were HIV seropositive, were younger, used cocaine, drank alcohol daily, and scored high on measures of depression and interpersonal problems were at a higher risk for discharge. Receipt of enhanced methadone treatment, which included case management services, group participation, psychiatric services, contingency-based reinforcers, and transportation assistance, was associated with a higher probability of retention, particularly in the first 90 days. These findings can be used to target individuals who are vulnerable to early discharge from treatment and to provide adjunctive services that may improve retention. Several of these predictors, particularly cocaine use and psychological problems, have also been associated with HIV risk among methadone clients. Increasing retention in methadone treatment will not only improve treatment efficacy but will also address the public health imperative to limit the transmission of HIV.

Methadone maintenance treatment and HIV risk-taking behaviour among injecting drug users in Berlin

STUDY OBJECTIVE

To determine whether methadone maintenance treatment (MMT) is effective in reducing the levels of HIV risk-taking behaviour (borrowing and lending of injection equipment, irregular condom use) among injecting drug users (IDUs), and to identify independent predictors of the borrowing of used syringes.

DESIGN

Cross sectional study of IDUs in MMT and not in MMT, using standardised interviews for collection of sociodemographic and behavioural data, and laboratory tests for detecting HIV antibodies.

SETTING AND PARTICIPANTS

The 612 IDUs were recruited at different services for drug users such as treatment centres, walk in agencies, a hospital, and on the streets.

MAIN RESULTS

Of all IDUs, 41% had borrowed and 34% had passed on used injection equipment in the previous six months. In univariate analysis, IDUs receiving MMT had injected less frequently and were significantly less likely to borrow and lend syringes. In logistic regression analysis, MMT was protective against the borrowing of syringes (adjusted odds ratio 0.36, 95% confidence interval 0.2, 0.8), but not against syringe lending nor against sexual risk behaviour (i.e., numbers of sex partners, lack of condom use). Important independent predictors of the borrowing of syringes were injecting drug use in prison, use of sedatives, and sex with another IDU in the previous six months.

CONCLUSIONS

MMT may play a significant role in reducing the levels of borrowing of syringes among IDUs. However, additional prevention measures are needed which should specifically address sexual risk behaviour and target subgroups of IDUs with high levels of needle sharing, such as IDUs who have been in prison and and those who are sedative users.

Background and overview of mental health and substance abuse treatment systems: meeting the needs of women who are pregnant or parenting

Women with a psychiatric disorder who also abuse alcohol or other drugs have historically encountered barriers to integrated treatment for both disorders. Substance abuse treatment services and mental illness treatment services are usually organized independently of each other and few are designed to meet the needs of pregnant and parenting women. This chapter reviews the developmental histories of treatment systems for psychiatric and substance abuse disorders; the structural barriers that impede the delivery of services to individuals with co-occurring psychiatric and substance abuse disorders; the prevalence of dual disorders; issues related to diagnosis and assessment, types of diagnoses and addictions; treatment issues specific to women who are pregnant or parenting; models of service delivery; and initiatives directed at changing treatment systems.

Treatment as harm reduction, defunding as harm maximization: the case of methadone maintenance

Despite numerous research studies demonstrating the efficacy of methadone maintenance treatment (MMT) in general and the value of retention in particular, the increasing defunding of this modality has compromised its potential. From 1990 to 1995 the lead author conducted a longitudinal research project to determine the impact of the cost of treatment on 233 San Francisco Bay Area study participants seeking, enrolled in, or defunded from MMT. This paper reports on selected findings from that study. Using variables of drug use, crime, gender and HIV risk, qualitative and quantitative results comparing those seeking treatment with those enrolled in treatment indicated that MMT functioned as a harm-reduction tool. When clients were defunded, however, drug use, crime and HIV risk increased and harm was maximized.

What happens when a demonstration project ends. Consequences for a clinic and its clients

The Los Angeles Enhanced Methadone Maintenance Project was a 5-year research demonstration project funded by the National Institute on Drug Abuse with the goal of reducing high-risk behavior for human immunodeficiency virus (HIV) among heroin users. A clinic was established for the purposes of the study and 500 clients with high-risk profiles were recruited into treatment. Follow-up assessments demonstrated that clients had reduced their drug use, criminal behavior, and HIV-risk behaviors after entering treatment. At the end of the project clients were given the option of continuing treatment at the clinic on a fee-for-service basis, transferring to another treatment provider, or undergoing detoxification. Clients who were eligible for Medicaid were likely to continue receiving methadone treatment, but those without Medicaid funding were not. The implications of terminating treatment among a high-risk population recruited into a research demonstration project are discussed.

HIV risk behaviors among women in methadone maintenance treatment

This article reports on the HIV risk behaviors of a sample of 158 women heroin addicts admitted into the Los Angeles Enhanced Methadone Maintenance Project. Risk behaviors for HIV were associated with age, lack of education, ethnicity, relationship with a drug user, HIV status, and higher scores on measures of illegal activity, suicidality, depression, polydrug use, and alcohol use. Significant reductions in number of male sex partners and needle-sharing partners were reported at follow-up, although frequency of condom use was unchanged. Methadone maintenance programs need to screen women for risk factors and assist them in developing new behavioral skills in order to implement a harm reduction approach to treatment.

Methadone maintenance treatment: an update

Available data (this review includes old major articles and recent articles) show that, although results are heterogeneous, methadone maintenance treatments (MMTs) have a real efficiency not only to reduce illicit opiate abuse (50-80% of patients under MMT did not use heroin in the preceding month) but also to reduce criminality, HIV risks and mortality, and to improve social rehabilitation, without inducing other alternative substance abuse. A minority of patients (perhaps 5-20%) stay on MMT on a very long-term basis (more than 10 years). Efficiency of MMTs are rather poorly related to patients' variables, with the exception of a moderately deleterious effect of a low age at onset of opiate dependence, a precocious or high involvement in criminality and an abuse of non-opiate drugs. On the other hand, variables related to treatment play a more important role in explaining heterogeneity of results. Optimal daily dose, high quality of medical and psycho-social services, clear orientation towards social rehabilitation and treatment retention (to allow a sufficient duration of treatment) and slow detoxification regimen of well-stabilized patients are all factors contributing to better results.

Therapeutic community methods in methadone maintenance (Passages): an open clinical trial

A non-random open clinical trial was conducted to determine whether a day-treatment program based on modified therapeutic community (TC) methods (Passages) produced better treatment outcomes for heroin addicts than did standard methadone maintenance therapy. Altogether, 327 methadone clients at two clinic sites were studied: 115 Passages members, and 212 comparison subjects. Compared to non-Passages clients, clients who voluntarily joined and remained in Passages for at least 6 months exhibited significantly larger reductions in cocaine use, heroin use, needle use, criminal activity, and psychological dysfunction. The present findings suggest that TC-oriented enhanced day-treatment can help methadone clients recover from drug abuse and adopt a prosocial lifestyle.

An enhanced positive reinforcement model for the severely impaired cocaine abuser

This article describes a cognitive-behavioral treatment approach that has been extensively modified to work with inner-city methadone-maintained cocaine users. Modifications were deemed essential to address the problems of engagement and retention in treatment that are typically encountered with this population. While this approach relies on such basic tenets of treatment as relapse prevention, cognitive restructuring, and psychoeducation, an understanding of the particular psychological vulnerabilities of this population has been incorporated into the model. The modified approach utilizes positive reinforcement extensively. This includes use of concrete reinforcers to facilitate initial engagement, and use of interpersonal reinforcers (therapist positive regard, attention, and respect) to increase program retention and sustain posttreatment change. Preliminary results indicate that 63% of patients can complete this intensive 6-month program, with considerable reductions in cocaine use and significant change in drug injection behavior.

Correlates of cocaine/crack use among inner-city incarcerated adolescents

Inner-city male adolescents in jail in New York City (N = 427) were interviewed to examine correlates of cocaine or crack use. Twenty-three percent had used cocaine or crack in the month before arrest and 32% reported lifetime use. Substantial rates of robbery, murder, other violent crime, weapons possession, and drug dealing were found. However, type of crime, including violent crime, was not related either to cocaine/crack use or to drug dealing. Current cocaine/crack users were more likely to use alcohol, marijuana, and intranasal heroin; to have multiple previous arrests; to be out of school; to be psychologically distressed; to have been sexually molested as a child; to have substance abusing parents; and to have cocaine/crack-using friends. They were also more likely to have frequent sex with girls, to be gay or bisexual, and to engage in anal intercourse. The findings should be considered in developing more effective drug abuse prevention and treatment interventions, and HIV prevention education, for incarcerated at-risk adolescents.

Condom use among criminally-involved adolescents

Condom use was studied for 421 sexually active, minority male adolescents who were currently in jail in New York City. Over three-quarters of the youths were users of alcohol and marijuana and about one-quarter were users of cocaine or crack, but drug injectors were rare. In the six months before arrest they had multiple sexual partners and about one-third had engaged in anal intercourse. Inconsistent condom use was the norm, with 17% reporting that they never used condoms and only 15% reporting that they used condoms every time for insertive sex. In multivariate analysis, more frequent condom use was independently predicted by gay/bisexual preference, greater acceptability and accessibility of condoms, partners' receptivity to use, self-initiation of use, and self-efficacy of avoiding AIDS. Condoms were used less frequently with steady than with causual partners, and rarely for anal or oral sex. AIDS prevention curricula addressing these factors should be delivered to high risk adolescents while they are temporarily accessible in jail.

Criminal involvement of cocaine users enrolled in a methadone treatment program

This was a study of criminal activities of cocaine users versus non-users enrolled in a methadone treatment program in New York City. Of those 140 methadone clients studied, 100 (71%) were cocaine users. There were no demographic differences between the two groups except marital status. Married clients (including common-law married) were more likely than never-married single clients to be non-users. Cocaine users were significantly more depressed, using the subscale of the Symptom Checklist-90. Although numbers of lifetime arrests and criminal involvement (in the year immediately preceding the research interview) of cocaine non-users were distinctively lower than those of users, the differences were not significant. In a multiple regression analysis, length of stay in the methadone program was the strongest predictor of criminal involvement. Those who were retained longer in the treatment were significantly less likely to be involved in criminal activities, regardless of cocaine use.
