A 3-year progress report on the implementation of LAAM in the United States.

AIMS: LAAM, a long-acting opioid agonist, was approved by the US Food and Drug Administration in 1993 for use in licensed narcotic treatment programs. These programs have the exclusive authority in the United States to dispense methadone and LAAM for the treatment of opiate dependence. The purpose of this report is to describe the course of LAAM's implementation and to document some of the factors that have influenced the time course and extent of this process. DESIGN: Narcotic treatment programs approved for LAAM use were contacted by telephone at three timepoints following the FDA approval of LAAM in 1993. FINDINGS: Regulatory hurdles have been the most significant factor in slowing the use of LAAM. Some clinics have enthusiastically moved LAAM into mainstream use with great success. At other clinics LAAM implementation has been impeded by staff resistance and management reluctance. Some specific clinical practices, such as provision of adequate dose levels and flexible dosing practices, appear to be associated with superior clinical response, but issues of staff and organizational attitude toward the new medication are probably the most important impediments to a more positive response. CONCLUSIONS: The tasks involved with introducing a new opiate agonist treatment into mainstream use in the United States are numerous and complex. Clinical policies, fiscal issues and regulatory factors must all be addressed. The introduction of LAAM into the treatment system provides some useful lessons as other new addiction pharmacotherapies are moved into mainstream use.

An intensive outpatient approach for cocaine abuse treatment. The Matrix model.

The Matrix model of outpatient treatment was developed during the 1980s in response to an overwhelming demand for cocaine abuse treatment services. The model was constructed using components based upon empirically supported findings from the substance abuse research field. Over the course of development, data were collected on the treatment model and the model was modified based upon empirical evaluation. A pilot study comparing the Matrix outpatient model with an inpatient hospital treatment program produced preliminary support for the clinical utility of the model. An open trial comparing publicly and privately funded patients demonstrated that patients with fewer resources were more difficult to engage and retain in this model of outpatient treatment. In a controlled trial, a clear positive relationship was documented between duration and amount of treatment involvement in the Matrix model and positive outcome at 1 year. Due to a variety of methodological issues, the study was not able to answer definitively the question of clinical efficacy. In all of these studies, patients treated with the Matrix model demonstrated statistically significant reductions in drug and alcohol use and improvements in psychological indicators. This body of work, along with the public acceptance the model has received in the treatment community, support the usefulness of this intensive outpatient approach for cocaine abuse. Further research is underway to provide additional controlled information on the value of this treatment approach.

Case management within a methadone maintenance program. A research demonstration project for HIV risk reduction.

The Los Angeles Enhanced Methadone Maintenance Project has incorporated case management in order to evaluate its effectiveness in reducing the risk of infection and/or transmission of human immunodeficiency virus among high-risk heroin addicts. Those recruited into the National Institute on Drug Abuse-funded treatment/research demonstration project were randomly assigned to either an enhanced group that received case management services or to a control group receiving standard methadone maintenance services. To date, the project has identified several barriers to implementation on a wide scale, including the inordinate amount of time spent assisting patients to procure basic necessities; the unwillingness of patients to participate in certain support services; and the reluctance of many service providers to work with methadone patients.
