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.

Interest in smoking cessation among injection drug users.

We describe the degree of nicotine addiction and readiness to quit smoking among people with a history of injection drug use, comparing those in a methadone maintenance treatment program (MMTP) with active illicit drug injectors in a needle exchange program (NEP). Interview data were collected from 452 persons in Providence, RI, from July 1997 to March 1998. Ninety-one percent (91%) of the population currently smoked cigarettes. Smokers were more likely to be female and from an NEP. Higher nicotine dependence by the Fagerstrom Test for Nicotine Dependence was found in Caucasians, those with a Methadone dose greater than 80 mg per day, those with less than high school education, and those with active alcohol abuse. Those more likely to be contemplating smoking cessation in the next six months were those from MMTP, older than 35, and without alcohol abuse. Although smoking cessation counseling should be offered to all smokers, interventions directed towards older individuals enrolled in MMTP may target the group most interested in smoking cessation.

Validation of the screening strategy in the NIAAA "Physicians' Guide to Helping Patients with Alcohol Problems".

OBJECTIVE: This study was undertaken to determine the diagnostic test characteristics of the alcohol screening strategy recommended in the National Institute on Alcoholism and Alcohol Abuse (NIAAA) "Physicians' Guide to Helping Patients with Alcohol Problems." METHOD: A research interview was performed on patients who presented to one urban emergency department (N = 395; 61% women). It asked three alcohol consumption questions, the CAGE questionnaire, and about past alcohol problems. The NIAAA-recommended screen was considered positive for alcohol consumption in excess of 14 drinks per week or 4 drinks per occasion for men, or 7 drinks per week or 3 drinks per occasion for women, or a CAGE score of 1 or greater. A sample of patients (n = 250) received the Composite International Diagnostic Interview substance abuse module, a gold standard interview, to determine lifetime or prior 12-month alcohol abuse or dependence; results were adjusted for verification bias. RESULTS: The prevalence of lifetime:alcohol abuse or dependence was 13%, for which the NIAAA strategy was 81% sensitive and 80% specific. The prevalence of alcohol abuse or dependence in the prior 12 months was 10%, for which the strategy was 83% sensitive and 84% specific. Its positive likelihood ratio exceeded that of the CAGE, augmented CAGE or consumption questions alone, and its negative likelihood ratio was the lowest. CONCLUSIONS: The screening strategy combining alcohol consumption and CAGE questions recommended in the NIAAA "Physicians' Guide" is valid, and has superior test characteristics compared to the CAGE alone, in this predominantly black (86%) emergency department population. Its brevity and simple interpretation recommend wider dissemination of the NIAAA "Physicians' Guide," although future research should examine its test characteristics in other clinical settings and with other populations.

Factors associated with readiness to change drug use among needle-exchange users.

To determine if frequent needle-exchange program (NEP) use is associated with lower readiness to change drug use, NEP clients in Providence, RI were interviewed regarding their drug use, HIV risk, health, and past use of drug treatment services in 1997-1998. Readiness to change drug use was assessed using a nine-step decision ladder. Based on this assessment, 14.3% of the sample were classified as precontemplators (24/168), 29.2% were in the contemplation stage (49/168), and 56.5% were in the determination or ready to change stage (95/168). We found that mean number of NEP visits was 25.5 among precontemplators, 28.7 among contemplators, and 22.5 among those in the determination stage. In multivariate analysis, an inverse relationship between having ever been in alcohol treatment and higher readiness to change drug use was the only significant association. In this exploratory study, we found that more frequent NEP participation did not impact readiness to change drug use among intravenous drug users. Given the high proportion of NEP clients ready to change drug use, improving linkages between NEPs and substance abuse treatment appears warranted.

Adverse drinking consequences among alcohol abusing intravenous drug users.

BACKGROUND: Heavy alcohol use is common among out-of-treatment injection drug users (IDUs); however, the relationship between alcohol and drug use behaviors in codependent populations is not well understood. Our specific objectives were (1) to describe the psychometric properties of the Drinker Inventory of Consequences (DrInC) in a sample of active IDUs, and (2) to compare DrInC scores of active IDUs with those reported for the alcohol treatment seeking sample on which the instrument was developed. METHODS: Interview data were collected from 187 active IDUs who scored positively (> or = 8) on the Alcohol Use Disorders Identification Test, who were recruited from a Providence, RI, needle exchange program (1998-1999). DrInC total and subscale scores for the 159 (85%) participants who met DSM-IV criteria for alcohol abuse/dependence were analyzed. Six-month follow-up data were used to estimate test-retest reliability. RESULTS: The DrInC total scale exhibited high internal consistency and test-retest reliability. With the exception of adverse physical consequences, reliability estimates for DrInC subscales were good to very good. These data indicate higher subscale redundancy than reported for the development sample. Active IDUs had significantly higher adverse impulse control consequences than the alcohol treatment seeking population on which the instrument was developed. CONCLUSIONS: The DrInC exhibits desirable psychometric properties for assessing adverse drinking consequences in active IDU populations. IDUs who met DSM-IV criteria for alcohol abuse/dependence reported overall levels of adverse drinking consequences comparable with non-IDU alcohol treatment populations but were more likely to exhibit adverse impulse control consequences.

Evaluating the effects of a brief motivational intervention for injured drinkers in the emergency department.

OBJECTIVE: The study aim was to test whether a brief motivational intervention, with or without a booster session, would improve drinking-related outcomes more than standard Emergency Department (ED) treatment. METHOD: The study population consisted of 539 (78% male) injured patients treated in the ED and discharged to the community following their treatment. Injured patients met inclusion criteria if they were assessed as hazardous or harmful drinkers by scoring eight or more on the AUDIT and/or having alcohol in their system at the time of their injury or ED visit. Patients were randomly assigned to either standard care (SC), brief intervention (BI) or brief intervention plus a booster session (BIB). At 1-year follow-up, 447 patients (83% of the sample) were re-interviewed to measure alcohol-related negative consequences, injuries and drinking. RESULTS: Patients receiving BIB, but not B1 patients, reduced alcohol-related negative consequences and alcohol-related injuries more than did those in the SC group. All three groups reduced their days of heavy drinking. Patients with histories of hazardous drinking responded to BIB, whether or not they had consumed alcohol prior to their injury. CONCLUSIONS: Together, these results indicate that the effects of a booster session that is added to a brief intervention in the ED can be helpful to injured patients with a history of hazardous or harmful drinking, irrespective of whether they have consumed alcohol prior to their injury.

Alcohol expectancies as a mediator of the relationship between injury and readiness to change drinking behavior.

There is a well-established relationship between alcohol expectancies and drinking behavior. The purpose of the present study was to extend the literature by examining the role of alcohol expectancies in determining readiness to change drinking behavior among injured emergency department patients who screened positive for hazardous drinking. Negative expectancies were found to partially mediate the relationships of alcohol-related injuries and injury aversiveness to readiness to change drinking behavior. Results suggest that negative alcohol expectancies are a potential means of increasing patients' readiness to change drinking behavior.

Depression among needle exchange program and methadone maintenance clients.

The objective of this study was to compare the prevalence of major depression in two cohorts of injection drug users, those enrolled in a Rhode Island Methadone Maintenance Treatment Program (MMTP) and those enrolled in a Rhode Island Needle Exchange Program (NEP) using cross-sectional interviews. Symptomatic and duration criteria for major depression in the last 6 months were identified using the Structured Clinical Interview for DSM-III-R (SCID). Among 528 persons interviewed, 54% of those in NEP and 42% of those in MMTP met criteria for major depression. Using multivariate logistic regression, women (odds ratio [OR] 2.5; 95% confidence interval [CI] 1.7-3.7), persons with alcohol use disorders (OR 1.7; 95% CI 1.1-2. 7), and persons without a current partner (OR 1.8; 95% CI 1.2-2.6) were more likely to be depressed controlling for age, race, education and HIV status. Persons enrolled in MMTP were less likely to be depressed (OR 0.6; 95% CI 0.4-0.8) than NEP. Higher rates of depression were found among NEP attendees than among those enrolled in MMTP. Mental health referrals should be part of the growing number of needle exchanges in the United States.

Adult offspring of alcoholic women as family history informants.

Eighteen years after their mothers had been hospitalized for alcoholism, adult offspring were asked if any of their 1st-degree relatives had ever had a drinking problem. Proband and informant characteristics that affect the validity of reports of maternal drinking problems given by adult offspring of alcoholic women were identified. A history of alcohol-related medical problems in the mother was associated with reporting maternal alcoholism. Being African-American, having a history of suicide attempts in the mother, and having a good maternal posttreatment outcome were associated with false-negative reports. Adding multiple offspring informants increased sensitivity to 86%. Female alcoholic offspring tended to underreport maternal alcoholism.

Alcoholism treatment, severity of alcohol-related medical complications, and health services utilization.

In efforts to contain costs and efficiently allocate resources, evaluation studies in alcoholism have increasingly assessed the effect of treatment on the use of health services through comparisons of treated and untreated alcoholics. The success of this approach requires that evaluators identify and adjust for differences between these two groups, thereby decreasing the likelihood that health utilization outcomes are attributed to the effects of treatment when in fact they may be related more to unidentified group differences. Using a sample of 63,873 hospitalized alcoholics, this study focused on one critical group difference, the severity of alcohol-related medical complications. Comparisons between treated alcoholics who either completed alcoholism treatment or detoxification only and untreated alcoholics with either primary medical/surgical or psychiatric diagnoses demonstrated the following: (a) untreated alcoholics with medical/surgical diagnoses were more likely to have severe alcohol-related medical complications than the other groups; (b) a positive linear relationship between health services utilization in the previous year and the severity of medical complications existed for all groups, except untreated alcoholics with psychiatric diagnoses; and (c) untreated alcoholics with psychiatric diagnoses with the most severe complications used fewer health services than any of the other three groups. Differences between treated and untreated alcoholics in both severity of medical complications and previous health utilization patterns demonstrate the need to identify and adjust for these factors in evaluation studies that examine the outcomes of alcoholism treatment.
