Methadone treatment practices and outcome for opiate addicts treated in drug clinics and in general practice: results from the National Treatment Outcome Research Study.
(9/746)
BACKGROUND: General practitioners (GPs) are increasingly urged to become more involved in the care and treatment of drug misusers. Little information is available about the effectiveness of treatments delivered in primary health care or specialist settings. The impact of treatment setting is investigated as part of the National Treatment Outcome Research Study (NTORS). This is the largest study of treatment outcome for drug misusers ever conducted in the United Kingdom (UK). AIM: This paper presents six-month treatment outcomes for patients who received community-based methadone treatment in either a specialist drug clinic or a general practice setting. METHOD: A prospective, multisite follow-up study of treatment outcome was conducted with 452 opiate addicts who had been given methadone treatment in primary health care and specialist clinic settings. Outcome data are presented for substance use behaviours, health, and crime. RESULTS: Improvements at follow-up were found among both the GP and the clinic-treated groups in drug-related problems, health, and social functioning. Problems at intake were broadly comparable among the clinic-based and the GP patients. Similar levels and types of improvement were found for both groups at six-month follow-up. CONCLUSIONS: Results demonstrate the feasibility of treating opiate addicts using methadone in primary health care settings, and show that treatment outcomes for such patients can be as satisfactory as for patients in specialist drug clinics. The GPs in our study are unrepresentative in their willingness to be actively involved with problem drug users; moreover, several services treated relatively large numbers of drug users. Issues surrounding the growth of 'GP specialists' are discussed. (+info)
Trends in funding and use of alcohol and drug abuse treatment at specialty facilities, 1990-1994.
(10/746)
OBJECTIVES: This study examined trends in funding and use of alcohol and drug abuse treatment at specialty facilities between 1990 and 1994. METHODS: The 1990 and 1994 National Drug and Alcohol Treatment Unit Surveys were used to estimate annual funding and number of clients in treatment. RESULTS: Public funding increased by 5%, whereas private funding decreased by 28% in real terms between 1990 and 1994. The number of publicly and privately funded clients decreased slightly. CONCLUSIONS: The rapid growth in private and public sector substance abuse funding during the 1980s has not continued into the 1990's. (+info)
A comparison of substance use between female inmates and female substance misusers in treatment.
(11/746)
Recent literature documents extensive substance misuse histories among US female prison inmates. The primary purpose of the present study was to determine whether histories of personal and familial substance misuse distinguished female inmates from substance misusers in treatment. After accounting for drug-related offences, we hypothesized that the inmates would have more extensive histories of personal and familial substance misuse and that they would have initiated substance use at an earlier age. Contrary to our expectations, the two samples were similar on many measures of alcohol and drug use. Similarly, differences in family histories of substance misuse were not in the predicted direction. As hypothesized, however, the inmates did report earlier age at onset of drinking. Of particular clinical relevance was the finding that, despite similar alcohol consumption levels, inmates reported fewer alcohol-related adverse medical, legal, and psychosocial consequences than did the treatment sample.

Consecutive epidemics of Q fever in a residential facility for drug abusers: impact on persons with human immunodeficiency virus infection.
(12/746)
Two large outbreaks of Q fever occurred in 1987 and 1988 in an agricultural community for the rehabilitation of drug users. Approximately 40% of the residents were human immunodeficiency virus (HIV)-positive. Two hundred thirty-five residents presented with clinical evidence of a flulike syndrome that was confirmed to be Q fever; moreover, a large proportion of residents developed an asymptomatic infection. Clinical signs and symptoms were rather nonspecific: fever, malaise, and muscle pain that were often associated with pulmonary symptoms. Single or multiple opacities were detected, with mild interstitial inflammation evident on chest roentgenograms. The source of infection was the sheepfold, which is part of the stock-farming activity of the community. Both outbreaks occurred just after lambing had begun. Residents who were exposed during the first epidemic were protected in the second one. The attack rate among HIV-positive residents was significantly higher than that among HIV-negative residents in the first outbreak, whereas only a slight, marginally significant difference was observed in the second outbreak. The clinical features of Q fever did not differ between HIV-positive and HIV-negative individuals. No cases of relapse or chronic disease were observed. (+info)
Medical and psychosocial services in drug abuse treatment: do stronger linkages promote client utilization?
(13/746)
OBJECTIVE: To examine the extent to which linkage mechanisms (on-site delivery, external arrangements, case management, and transportation assistance) are associated with increased utilization of medical and psychosocial services in outpatient drug abuse treatment units. DATA SOURCES: Survey of administrative directors and clinical supervisors from a nationally representative sample of 597 outpatient drug abuse treatment units in 1995. STUDY DESIGN: We generated separate two-stage multivariate generalized linear models to evaluate the correlation of on-site service delivery, formal external arrangements (joint program/venture or contract), referral agreements, case management, and transportation with the percentage of clients reported to have utilized eight services: physical examinations, routine medical care, tuberculosis screening, HIV treatment, mental health care, employment counseling, housing assistance, and financial counseling services. PRINCIPAL FINDINGS: On-site service delivery and transportation assistance were significantly associated with higher levels of client utilization of ancillary services. Referral agreements and formal external arrangements had no detectable relationship to most service utilization. On-site case management was related to increased clients' use of routine medical care, financial counseling, and housing assistance, but off-site case management was not correlated with utilization of most services. CONCLUSIONS: On-site service delivery appears to be the most reliable mechanism to link drug abuse treatment clients to ancillary services, while referral agreements and formal external mechanisms offer little detectable advantage over ad hoc referral. On-site case management might facilitate utilization of some services, but transportation seems a more important linkage mechanism overall. These findings imply that initiatives and policies to promote linkage of such clients to medical and psychosocial services should emphasize on-site service delivery, transportation and, for some services, on-site case management.

Methadone treatment and HIV and hepatitis B and C risk reduction among injectors in the Seattle area.
(14/746)
Drug treatment has the potential to reduce incidence of blood-borne infections by helping injection drug users (IDUs) achieve abstinence or by decreasing the frequency of injection and sharing practices. We studied the associations between retention in methadone treatment and drug use behaviors and incidence of hepatitis B and C in a cohort of IDUs in the Seattle, Washington, area. Data on IDUs entering methadone treatment at four centers in King County, Washington, were collected through face-to-face interviews using a standardized questionnaire at baseline and 12-month follow-up between October 1994 and January 1998. Blood specimens were obtained and tested for human immunodeficiency virus (HIV) and hepatitis B and C. Drug treatment status at follow-up was analyzed in relation to study enrollment characteristics and potential treatment outcomes, including injection risk behaviors, cessation or reduced frequency of injection, and incidence of hepatitis B and C. Of 716 IDUs, 292 (41%) left treatment, 198 (28%) disrupted (left and returned) treatment, and 226 (32%) continued treatment throughout the 1-year follow-up period. Compared to those who left treatment, subjects who disrupted or continued were less likely to inject at follow-up (odds ratio [OR] = 0.5, 95% CI 0.3-0.7; and OR = 0.1, 95% CI 0.1-0.2, respectively). Among the 468 (65%) subjects who continued injecting, those who continued treatment injected less frequently, were less likely to pool money to buy drugs (OR = 0.5, 95% CI 0.3-0.8) and inject with used needles (OR = 0.5, 95% CI 0.2-0.8) compared to those who left treatment. Cooker or cotton sharing was not associated with retention in treatment, but hepatitis B incidence was lowest among those who continued treatment. The results of this study suggest drug use risk reduction is more likely to be achieved by those who remain in drug treatment and by those who stop injecting, but that those who drop out and return and those who continue to inject while in treatment may also benefit. This supports the role of consistent drug treatment in an overall harm-reduction strategy. (+info)
Drug injection rates and needle-exchange use in New York City, 1991-1996.
(15/746)
Objectives included (1) to develop methods for identifying injection drug users with accelerating injection habits so they might be referred to counseling and treatment and (2) to investigate behavioral correlates of accelerating injection habits, including syringe-exchange program utilization. Data on drug use, enrollment in methadone maintenance, and demographic variables were obtained from 328 subjects who were seronegative for human immunodeficiency virus (HIV) who attended anywhere from 4 to 11 quarterly study visits for interview, HIV pretest counseling and risk reduction counseling, and blood donation for HIV antibody testing. Subjects were recalled 2 weeks after each study visit to receive their results and post-test counseling. We characterized subjects according to their patterns of drug injection as accelerating, decelerating, or stable, using intraindividual regression analyses and categorization rules, and by syringe-exchange use as consistent users, sporadic users, or nonusers. The present subjects included 52% with decelerating, 29% with stable, and 19% with accelerating rates of drug injection. There were 128 subjects (39%) who were categorized as consistent users of syringe-exchange programs, 84 (25%) were categorized as sporadic users, and 116 (35%) were categorized as nonusers. All syringe-exchange groups showed significantly decelerating drug injection. Rates of decline were significantly less, however, among consistent syringe-exchange users than sporadic or nonusers of syringe exchanges. Categorical analysis also showed significant differences among groups, with 30% of consistent syringe-exchange program users having accelerating rates of drug injection compared to 9% of nonusers and 17% of sporadic users. That consistent syringe-exchange users included a larger proportion of individuals whose drug habits were accelerating than did sporadic users or nonusers of syringe exchanges suggests a need for improved identification and counseling of such subjects by syringe-exchange program staff. The present statistical approaches may be of value in targeting such efforts. The ability of a syringe-exchange program to attract a disproportionate share of drug users with accelerating rates of drug injection underscores the importance of these programs to HIV prevention efforts.

The outcome and cost of alcohol and drug treatment in an HMO: day hospital versus traditional outpatient regimens.
(16/746)
OBJECTIVE: To compare outcome and cost-effectiveness of the two primary addiction treatment options, day hospitals (DH) and traditional outpatient programs (OP) in a managed care organization, in a population large enough to examine patient subgroups. DATA SOURCES: Interviews with new admissions to a large HMO's chemical dependency program in Sacramento, California between April 1994 and April 1996, with follow-up interviews eight months later. Computerized utilization and cost data were collected from 1993 to 1997. STUDY DESIGN: Design was a randomized control trial of adult patients entering the HMO's alcohol and drug treatment program (N = 668). To examine the generalizability of findings as well as self-selection factors, we also studied patients presenting during the same period who were unable or unwilling to be randomized (N = 405). Baseline interviews characterized type of substance use, addiction severity, psychiatric status, and motivation. Follow-up interviews were conducted at eight months following intake. Breathanalysis and urinalysis were conducted. Program costs were calculated. DATA COLLECTION: Interview data were merged with computerized utilization and cost data. PRINCIPAL FINDINGS: Among randomized subjects, both study arms showed significant improvement in all drug and alcohol measures. There were no differences overall in outcomes between DH and OP, but DH subjects with midlevel psychiatric severity had significantly better outcomes, particularly in regard to alcohol abstinence (OR = 2.4; 95% CI = 1.2, 4.9). The average treatment costs were $1,640 and $895 for DH and OP programs, respectively. In the midlevel psychiatric severity group, the cost of obtaining an additional person abstinent from alcohol in the DH cohort was approximately $5,464. Among the 405 self-selected subjects, DH was related to abstinence (OR = 2.1; 95% CI = 1.3, 3.5). CONCLUSIONS: Although significant benefits of the DH program were not found in the randomized study, DH treatment was associated with better outcomes in the self-selected group. However, for subjects with mid-level psychiatric severity in both the randomized and self-selected samples, the DH program produced higher rates of abstention and was more cost-effective. Self-selection in studies that randomize patients to services requiring very different levels of commitment may be important in interpreting findings for clinical practice. (+info)
