This paper presents the findings of studies of the alcohol treatment system in two California counties. It identifies the functions carried out by treatment providers, many of which differ from and occasionally contradict official program goals. Reasons for these discrepancies stem from political as well as economic factors. Demands have been made on the treatment system to deliver services which traditionally were provided by the criminal justice and welfare systems. The shift is also explained by the unique historical development and ideological character of the alcohol treatment system. The study identifies several changes in the service delivery system, which include client demographics and problem definitions. Implications of these changes involve a de facto compromise of the more traditional treatment ethics and class bias in the process of client selection.

In both developed nations and the developing world, there is a clear trend towards addressing alcohol, tobacco, and other drug problems through health and social services. There are several persuasive arguments for this shift beyond pure economics, which include comorbidity, cost effectiveness, coordination of care and effectiveness. This is the first volume to pull together effective methods that can be used for addressing substance abuse through health and social service systems. It also integrates interventions for a range of drugs of abuse, rather than focusing on only one (such as alcohol). The book's international perspective also makes this a unique contribution to the existing literature

This study identifies longitudinal psychiatric trajectories of 934 adult individuals entering chemical dependency treatment in a private, managed care health plan and examines the relationship of these trajectories with substance use (SU) outcomes. The authors apply a group-based modeling approach to identify trajectory groups based on repeated measures of psychiatric severity for 9 years and identify four distinct groups. Results of multivariate logistic generalized estimating equation models find an association between psychiatric trajectories and long-term SU. Older cohorts and life course measures of marital status and employment status as individuals changed over time are related to drug and some alcohol outcomes.

BackgroundThe treatment of alcohol and other drugs is now more commonly framed in terms of a chronic condition which requires ongoing monitoring. A model which includes continuing access to health care may optimize outcomes. Most studies of chronic care models have not included health care and have only examined short term effects.MethodsThe sample (n = 783) included consecutive admissions in ten public and private alcohol and other drug (AOD) treatment programs followed over seven years. The outcome was remission which was defined as alcohol and drug abstinence or non-problem use.ResultsIn the private sample, receiving health care services predicted remission across the seven years; however this did not occur in the public sample. More patients in the public treatment sample received AOD treatment readmissions each year, while more of those in the private sector received psychiatric and general health visits. Except for drug problem severity, there were no other clinical differences between the samples. There were no differences in the proportions of patients in the two sectors who received the full spectrum of chronic care services. In the final models, 12-step participation was markedly significant for both samples.ConclusionsModels of chronic care for substance use need to consider differences between private and public treatment and should take into account that individuals may not always have access, or avail themselves of services that may optimize long-term outcomes.

Health services research is a multidisciplinary field that examines ways to organize, manage, finance, and deliver high-quality care. This specialty within substance abuse research developed from policy analyses and needs assessments that shaped federal policy and promoted system development in the 1970s. After the authorization of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institute on Drug Abuse (NIDA), patient information systems supported studies of treatment processes and outcomes. Health services research grew substantially in the 1990s when NIAAA and NIDA moved into the National Institutes of Health and legislation allocated 15% of their research portfolio to services research. The next decade will emphasize research on quality of care, adoption and use of evidence-based practices (including medication), financing reforms and integration of substance abuse treatment with primary care and mental health services.

The growth curve modeling (GCM) technique has been widely adopted in longitudinal studies to investigate progression over time. The simplest growth profile involves two growth factors, initial status (intercept) and growth trajectory (slope). Conventionally, all repeated measures of outcome are included as components of the growth profile, and the first measure is used to reflect the initial status. Selection of the initial status, however, can greatly influence study findings, especially for randomized trials. In this article, we propose an alternative GCM approach involving only post-intervention measures in the growth profile and treating the first wave after intervention as the initial status. We discuss and empirically illustrate how choices of initial status may influence study conclusions in addressing research questions in randomized trials using two longitudinal studies. Data from two randomized trials are used to illustrate that the alternative GCM approach proposed in this article offers better model fitting and more meaningful results.

Research has identified a wide range of health conditions related to alcohol and drug use in studies conducted primarily in developed countries and in populations with severe alcohol and drug problems. Little is known about medical conditions in those with less severe alcohol and drug use in developing countries. We used WHO AUDIT and ASSIST screeners to identify hazardous drinking or drug use in public health clinics in Cape Town, South Africa, and included questions about doctor-diagnosed medical conditions. Using logistic regression we examined the relationship of medical conditions to hazardous alcohol, drug and tobacco use. Those with hazardous substance use had higher prevalence of many health conditions including tuberculosis, Hepatitis B, migraine, chronic bronchitis, and liver cirrhosis. Optimal treatment for some medical conditions may include treatment of underlying hazardous substance use, particularly use of drugs other than alcohol. In these populations, access to substance use treatment is limited and even brief interventions or advice may be useful.
