Effects of residence in Alzheimer disease special care units on functional outcomes.

Context: Alzheimer disease special care units (SCUs) in nursing homes are increasingly prevalent, but little is known about their effects on residents' outcomes.

Objective: To analyze the effect of SCU residence on the rates at which residents decline in functional status.

Design: A cohort of nursing home residents assessed at multiple points during about 1 year.

Measuring program performance in methadone treatment using in-treatment outcomes: an illustration.

Quality measurement and quality assurance in substance abuse treatment have, over the past few years, become a major policy issue. In addition, there is interest in the degree to which client outcomes can play a role in measuring treatment program performance. This article discusses the movement toward outcome-based performance measurement in substance abuse treatment.

Relationship between drug preference and indicators of psychiatric impairment.

This study was conducted to investigate the relationship between the indicators of psychiatric disorders of individuals and their choice of either cocaine or heroin, drugs that differ markedly in their pharmacological effects. Cocaine acts as an intense stimulant, and heroin has profound sedative effects. This investigation examined the relationship between preference for heroin or cocaine and indicators of psychiatric impairment.

Treatment services in two national studies of community-based drug abuse treatment programs.

Findings from a number of sources over the past decade have documented a decline in the resources available for drug abuse treatment and the services being provided to clients in community-based drug abuse treatment programs. We compared client reports of services received and unmet service needs in a national crossmodality sample of clients in two studies of drug abuse treatment: the Treatment Outcome Prospective Study (TOPS), 1979-1981, and the Drug Abuse Treatment Outcome Study (DATOS), 1991-1993. Findings showed a marked decrease over the past decade in the number and variety of services clients reported receiving.

Issues to consider when predicting retention in therapeutic communities.

Many studies have focused on retention in therapeutic communities (TCs) because research shows that retention is an important predictor of client outcomes from these programs. A comparison of the three largest studies found there was little overlap between predictors of retention in TCs. Treatment Outcome Prospective Study data were analyzed to assess whether these findings may have been due to differences in times when the data were collected, measures of length of stay, and domains of variables used to predict retention.

Exposure to methadone programs and heroin use.

The aims of this study were to: (a) assess the effects of various patterns of exposure to methadone programs on heroin use; (b) assess the effects of other patient, program, and treatment variables; and (c) identify variables that promote the type of exposure to methadone programs that is most effective for reducing heroin use. The sample was 526 patients who were admitted from 1979 to 1981 into 17 methadone programs that participated in the Treatment Outcome Prospective Study. The study differs from previous research in that it addresses the time that patients spent in methadone programs during the follow-up period in defining exposure patterns.

Do methadone patients substitute other drugs for heroin? Predicting substance use at 1-year follow-up.

Data were analyzed from the nationwide Treatment Outcome Prospective Study (TOPS) to assess whether current and former methadone patients substitute other drugs for heroin. The sample comprised 513 heroin users who were admitted to methadone programs in 10 cities across the United States and followed for at least 1 year. Structured face-to-face interviews were administered at admission and at follow-up to assess use of six substances: cocaine, amphetamines, illegal methadone, tranquilizers, marijuana, and alcohol.

Predicting cocaine use among methadone patients: analysis of findings from a national study.

Findings from a large-scale national study of clients admitted to publicly funded drug treatment programs between 1979 and 1981 were used to determine whether cocaine use by current and former methadone patients could be predicted. The sample for this analysis comprised 526 daily or weekly heroin users admitted to 17 methadone maintenance programs. The study found that cocaine use by both current and former methadone patients showed an overall decline during the follow-up year; that patients who stopped using heroin after entering treatment were much more likely to quit using cocaine than were their heroin-using counterparts; and that the odds of initiating cocaine use after admission to a methadone program were much higher among patients who continued using heroin.

Choice of payment plan in the Medicare capitation demonstration.

This article identifies factors that influence the choice between joining an HMO and remaining with the traditional fee-for-service system among aged Medicare beneficiaries in three communities. Sources of marketing information were found to be strongly and positively related to the decision to join the HMO. Among beneficiaries who had to switch providers to join, persons who had a prior usual source of care and those who were satisfied with the amount of paperwork required to use that source of care were less likely to enroll in the HMO.
