Implications of managed care in a publicly funded health care delivery system

In the light of federal cuts in the Medicaid budget, the Medicaid-funded health delivery system is under severe cost pressures, especially in publicly funded institutions. In the private health insurance industry, managed care innovations have successfully restrained costs. For publicly funded institutions to remain viable, managed care contracts must be implemented for the Medicaid system as well. Managed care holds promise for reducing costs as well as reducing many of the current barriers to quality health care for the indigent.

Sociodemographic representation in published studies of cocaine abuse pharmacotherapy

This study evaluated: (1) the reporting of sociodemographic characteristics of research subjects in published outpatient studies of cocaine abuse pharmacotherapy; (2) the association of study characteristics with such reporting and with the distribution of characteristics; and (3) the comparison of sociodemographic characteristics in the research subjects with those of a community-based sample of cocaine abusers who had sought treatment. Medline search identified 68 articles on cocaine abuse outpatient pharmacotherapy published from 1983 to 1993 in an English language, peer-reviewed journal. Sociodemographic characteristics of research subjects (n = 1802) were compared with those of respondents (weighted n = 135) to the National Comorbidity Survey (1990-1992), who reported at least one cocaine-related problem and had sought substance abuse treatment. Only three (4.4%) articles reported all six of the following sociodemographic characteristics of their subjects: 82.4%, reported mean age; 58.8%, race/ethnicity; 85.3%, sex; 22.1%, employment status; 13.2%, educational status; and 5.9%, socioeconomic status/income. Compared to survey respondents, research subjects were significantly more likely to be African-American and live in the Northeast region of the US and marginally more likely to be male and currently unemployed. These findings indicate that many published articles do not follow currently recommended guidelines for describing sociodemographic characteristics of research subjects and that, aside from race/ethnicity and geographic location, research subjects are fairly comparable in basic sociodemographic characteristics to the larger population of treatment-seeking individuals with cocaine-related problems.

The impact of public health media campaigns on drug users

Evaluation of public health media campaigns to influence change in high-risk behavior often bemoans a lack of relevance to the target audiences as well as an absence of integrated interpersonal and mass-mediated communication channels. The assumption that illegal drug users are disconnected from mass-mediated communication may account for this absence of media interventions. However, the authors' HIV-prevention research project demonstrates that many out-of-treatment drug users are media consumers. Furthermore, it shows that participants who recalled seeing or hearing media interventions report greater levels of positive behavior change than participants who do not recall such messages. Results suggest strong coordination of human services messages that are relevant to out-of-treatment drug users to facilitate changes in behavior.

An analysis of unmet need for HIV services: The Houston Study

HIV/AIDS is indicative of general institutional neglect that disproportionately affects minorities, poor, and underserved populations. Among women and minorities, HIV infection is associated with preexisting economic distress. Moreover, socioeconomic resources, gender, and race/ethnicity may determine access to medical and nonmedical services that affect disease progression. An analysis of data collected for the Ryan White Care Act needs assessment in Houston, Texas, was performed to assess the effects of socioeconomic and demographic factors on unmet needs for existing medical, social, and counseling services, adjusting for the effects of illness and substance abuse. Results indicated that lower income and Hispanic ethnicity were associated with the unmet need for medical services. Higher income was positively associated and African American ethnicity was negatively associated with the unmet need for social services. Also, higher income and private insurance were negatively associated with counseling services. The authors suggest that these latter findings may result from program eligibility requirements and respondents' hierarchy of needs, respectively.

Attitudes, norms, self-efficacy, and stage of change among out-of-treatment female crack cocaine users: a pilot study

The level of sexual risk among crack cocaine uses had remained high, regardless of their level of AIDS knowledge. Consequently, researchers have advocated the use of rigorous behavioral theory in aiding epidemiological research and intervention. To test whether stage of change for "insisting that men (besides your main partner) use condoms every time you have sex with them" was associated with behavioral attitudes, subjective norms, and self-efficacy among female crack cocaine users, a behavioral context questionnaire was administered to 61 female crack cocaine users who were recruited in the field and interviewed in an urban HIV testing center. Results indicated that all three were associated with stage of change and that self-efficacy was the variable most strongly related to stage of change.

Therapeutic connection and client progress in drug abuse treatment

This article explores the effects of the therapeutic connection between the drug abuse treatment client and the treatment counselor on the client's progress in psychological functioning during the course of treatment. Two hypotheses of the relationships between therapeutic connection and psychological functioning are formulated. The first predicts that higher levels of connection will be associated with greater improvement in the client's level of psychological functioning. The second predicts that higher levels of functioning at intake will, in turn, be associated with greater connection to counselor. Results from a longitudinal study of 139 participants in a federally sponsored pilot drug abuse treatment program in Houston, Texas show statistically significant associations between both a client's initial level of psychological functioning and therapeutic connection to counselor and between this connection and subsequent improvement in functioning.

Managed care, cost-effectiveness, and rehabilitation: the case of HIV

Because of its cost-effective approach to impairment and disability, rehabilitation therapy is uniquely positioned to assume a significant role in today's healthcare environment. As the cost of health care has become a major concern, both the government and the private insurance industry have turned toward rehabilitation services as resources for preventing more costly use of the healthcare system in the future. Although funding in the area of injury research scarce, funding for demonstrating the success of therapies for chronic illness such as HIV is more plentiful. In the case of HIV, rehabilitation nursing techniques and principles can be used as a model for reducing the substantial social costs of the disease. Specifically, rehabilitation nurses can assume a leadership role as service coordinators for HIV-positive patients. If rehabilitation nurses perform this role effectively and participate fully in research efforts aimed at measuring the success of rehabilitation therapy, their efforts have the potential of permanently raising the status of the rehabilitation nursing specialty.

An assessment of the risks of syphilis and HIV infection among a sample of not-in-treatment drug users in Houston, Texas

The research presented in this paper details the results of an assessment of the risk factors associated with having a positive syphilis or HIV serology. The study was conducted using a sample of not-in-treatment drug users volunteering to participate in an HIV risk reduction intervention. The sample was composed of individuals who had injected drugs within 30 days or smoked crack cocaine 48 hours prior to participation in the study. Study participants were approximately 75% male and 66% African-American. All participants provided a blood sample to be tested for HIV and syphilis. Analysis of risk was conducted using univariate and multivariate statistical methods. Multivariate analysis of blood results showed that women, African-Americans, and those having a positive blood test for HIV were at higher odds of having a positive syphilis test. Analysis also showed that being a gay or bisexual male, having a history of drug injection, having less than a high-school education, having a history of trading sex for money, being African-American, and having a positive blood test for syphilis significantly increased the odds of a positive HIV test. Implications for HIV and STD prevention are discussed.

Point-of-care systems, informatics, and health care delivery

Evolving information technology has had profound effects on business operations and the marketplace. The health care services industry, particularly hospitals, clinics, and medical offices, has historically lagged behind other industries in the implementation of comprehensive, integrated, computerized data management tools. Health care reformers are looking to the promises of the information technology "revolution" as a means of improving systemic efficiency and health care quality. This study discusses the impact of informatics, or information technology, on the delivery of health care services. We present the evolution of informatics and the predicted future benefits of integrated computerized patient records and point-of-care systems.

Determinants of HIV seroprevalence rates among sites participating in a community-based study of drug users

The National Institute on Drug Abuse's National Cooperative Agreement Project is a nationwide study of the injection and sexual behaviors of three populations of out-of-treatment drug users: injecting drug users (IDUs) who did not smoke crack cocaine, non-injecting crack smokers, and those engaging in both types of use. The goal of the analyses we present was identification of subsets of behavioral variables that would, within each type of drug use, distinguish sites by HIV seroprevalence level. Among non-crack-smoking IDUs high seroprevalence rates were associated with race and sex, the overall frequency of injection, the frequency of cocaine injection, and geographic location. Among noninjecting crack smokers, cities were distinguished by the frequency of exchanging sex for money, the number of sex partners, the local seroprevalence rate among IDUs, and location. Among subjects engaging in both types of use, seroprevalence rates among sites was distinguished by the frequency of exchanging sex for drugs and location.

Economic perceptions and expectations of out-of-treatment drug users

The effect on mainstream behavior of current economic conditions and expectations for the future is frequently the subject of public opinion polls. However, economic perceptions may also influence the behaviors of those in "hidden" populations, such as drug users. An Economic Perceptions Index (EPI) was developed and administered to 261 out-of-treatment drug users in Houston, Texas. Results suggest that drug users' general perceptions of the economy are based on their own economic situation, and that there is a relation between a pessimistic view of the economy and drug use. They also suggest that lack of municipal infrastructure may pose more of a barrier to users' seeking employment than job search skills.

Epidemiology of coca derivatives use in the Andean region: a tale of five countries

The countries of the Andean Region (Bolivia, Colombia, Ecuador, Peru, and Venezuela) have recently reported findings from drug use surveys. An integrated comparison of their results and the results from other countries is presented. A total of 24,108 people were surveyed. Lifetime prevalence of cocaine or coca paste use was between 0.8 and 3.0%. The highest prevalence of coca paste or cocaine use was found among individuals who were middle-age, middle-class, males, people who finished high school, those who had high income, and urban dwellers. The most frequent age of first use was 15 to 24 years. The study shows that coca and derivatives use is a public health problem that is affecting a productive segment of the population of this region.

Increasing opiate abstinence through voucher-based reinforcement therapy

Heroin dependence remains a serious and costly public health problem, even in patients receiving methadone maintenance treatment. This study used a within-subject reversal design to assess the effectiveness of voucher-based abstinence reinforcement in reducing opiate use in patients receiving methadone maintenance treatment in an inner-city program. Throughout the study subjects received standard methadone maintenance treatment involving methadone, counseling, and urine monitoring (three times per week). Thirteen patients who continued to use opiates regularly during a 5-week baseline period were exposed to a 12-week program in which they received a voucher for each opiate-free urine sample provided: the vouchers had monetary values that increased as the number of consecutive opiate-free urines increased. Subjects continued receiving standard methadone maintenance for 8 weeks after discontinuation of the voucher program (return-to-baseline). Tukey's posthoc contrasts showed that the percentage of urine specimens that were positive for opiates decreased significantly when the voucher program was instituted. (P < or = 0.01) and then increased significantly when the voucher program was discontinued during the return-to-baseline condition (P < or = 0.01). Rates of opiate positive urines in the return-to-baseline condition remained significantly below the rates observed in the initial baseline period (P < or = 0.01). Overall, the study shows that voucher-based reinforcement contingencies can decrease opiate use in heroin dependent patients receiving methadone maintenance treatment.

Drug abuse, AIDS, and the coming crisis in long-term care

As the 21st century approaches and the proportion of the US population over 65 years of age increases, it is expected that the demand for long-term care will expand dramatically. This expectation has been widely discussed. Less widely discussed is a potential for increase in the demand for long-term care resulting, not from the geriatric conditions with which the industry is already familiar, but from chronic and debilitating substance abuse-related diseases. In the United States, the incidence of severe cardiovascular and hepatological deterioration in younger patients has begun to increase, partly due to the increased scope of drug use and the increased variety of drugs used by individuals under the age of 35. HIV disease progression resembles these degenerative conditions in some important ways, and HIV infection is now often accompanied by substance abuse disorders. Thus, the care of HIV-infected patients can serve as a model for the impact on the long-term care industry that this new type of patient is likely to make. Using HIV as a particularly dramatic example, this paper discuss those changes in detail, and concludes with recommendations for successfully adapting to them.

Sustained cocaine abstinence in methadone maintenance patients through voucher-based reinforcement therapy

BACKGROUND

Chronic cocaine abuse remains a serious and costly public health problem. This study assessed the effectiveness of a voucher-based reinforcement contingency in producing sustained cocaine abstinence.

METHODS

A randomized controlled trial compared voucher-based reinforcement of cocaine abstinence to noncontingent voucher presentation. Patients were selected from 52 consecutively admitted injecting heroin abusers in a methadone maintenance treatment program. Patients with heavy cocaine use during baseline period (N = 37) participated. Except where otherwise indicated, the term cocaine abuse is used in this article in a generic sense and not according to the DSM-III-R definition. Patients exposed to abstinence reinforcement received a voucher for each cocaine-free urine sample (ie, negative for benzoylecgonine) provided three times per week throughout a 12-week period; the vouchers had monetary values that increased as the number of consecutive cocaine-free urine samples increased. Control patients received noncontingent vouchers that were matched in pattern and amount to the vouchers received by patients in the abstinence reinforcement group.

RESULTS

Patients receiving vouchers for cocaine-free urine samples achieved significantly more weeks of cocaine abstinence (P = .007) and significantly longer durations of sustained cocaine abstinence (P = .001) than controls. Nine patients (47%) receiving vouchers for cocaine-free urine samples achieved between 7 and 12 weeks of sustained cocaine abstinence; only one control patient (6%) achieved more than 2 weeks of sustained abstinence. Among patients receiving vouchers for cocaine-free urine samples, those who achieved sustained abstinence ( > or = 5 weeks) had significantly lower concentrations of benzoylecgonine in baseline urine samples than those who did not achieve sustained abstinence (P < or = .01). Patients receiving voucher reinforcement rated the overall treatment quality significantly higher than controls (P = .002).

CONCLUSION

Voucher-based reinforcement contingencies can produce sustained cocaine abstinence in injecting polydrug abusers.

Motivating physician behaviour change: social influence versus financial contingencies

The recent development of clinical practice heuristics is a logical consequence of outcomes and effectiveness research. Proponents of clinical practice guidelines (CPGs) believe they will lower costs, enhance quality, and reduce the incidence of malpractice claims. Although the process for generating CPGs appears relatively uncomplicated, guidelines alone do not produce lasting changes in physician behaviour. Discusses strategies for implementing CPGs based on the various factors that influence physician behaviour. Recommends direct behaviour management strategy based on financial contingencies.

Effectiveness of adjunct therapies in crack cocaine treatment

Although intensive outpatient therapy is recommended for treatment of cocaine, psychosocial characteristics associated with crack cocaine abuse are also implicated in attrition from outpatient programs. Acupuncture, medications, and brainwave therapy (biofeedback), have all been used to encourage treatment retention and drug use outcomes. The effectiveness of three adjunct therapies in improving retention and drug use outcomes in intensive outpatient cocaine treatment was tested in a primarily young, indigent African-American sample of crack cocaine users at a community hospital in a low-income, high drug use neighborhood in Houston. Subjects were assigned to receive either neurobehavioral treatment alone or neurobehavioral with one of three adjunct therapies. These included acupuncture, anticraving medication, or brainwave therapy. Comparative results indicated that dosage of any adjunct therapy was associated with days in treatment and standard treatment sessions attended, and that standard treatment sessions attended was associated with negative urinalysis results at follow-up. None of the adjunct therapies were directly associated with drug use outcomes.

Fostering a drug-free workplace

Drug abuse costs American industry and the public an estimated $100 billion a year. As a result, workplace drug testing programs have become a serious option for many companies. Federal guidelines regarding testing and laboratories are in place. An overview of the current components necessary in designing a corporate drug testing program that complies with these guidelines is presented. Essential features of a corporate workplace drug testing program, that is, the policy, the testing process, and the laboratory contracted to test employees, are detailed from designs suggested in the current literature and in compliance with federal guidelines. Developing a cost-effective corporate program that meets federal guidelines, stands up to court scrutiny, and is universally accepted by employees is the objective of a drug testing program. The challenge can be met by building consensus, spelling out policy, maintaining high testing standards, and above all making rehabilitation of employees who test positive the ultimate goal of a drug-free workforce/workplace.

To hang in the 'hood: description and analysis of outreach activities

The unique, influential, and successful characteristics of outreach as a risk behavior reduction intervention among active drug users is examined. The history of outreach is posited as a delineation of roles, and the outreach process as one of communication and role enactment. The premise is that the outreach worker's juxtaposition of multiple communicative roles facilitates success with HIV outreach interventions. The word "outreach" implies a desired object that eludes one's ready grasp. In the attempt to educate the active drug user about HIV risk behavior, it is the addict that often eludes the educator's ready grasp; a small dilemma for the creative outreach worker. An ethnographic description is provided of four different outreach workers' abilities to penetrate social networks, locate and recruit hidden populations, contextualize client behavior, respond to client needs, and build trust necessary to engage them in risk reduction interventions, while still adhering to program recruitment guidelines. Investigative, study, and outreach limitations are discussed.

The case for a code of ethics in an ambulatory care setting

The health care industry leads others in the development and use of professional codes of ethics. However, ambulatory care facilities continue to operate without coherent ethical guidelines addressing the workplace itself. New diagnostic and treatment capabilities, coupled with economic pressures, have intensified the ethical dilemmas facing the ambulatory care practice. This article argues that office codes of ethics decrease the risk of liability exposure, clarify the expectations of patients and staff, and foster responsible ethical reflection in the workplace. Material for this article was gathered from relevant literature in the areas of business ethics, bioethics, and health care management.

Double-blind comparison of carbamazepine and placebo for treatment of cocaine dependence

This study was conducted to determine the effectiveness of carbamazepine (CBZ) for treatment of cocaine dependence. Sixty-two (CBZ = 28, placebo = 34) cocaine-dependent (DSM-III-R criteria) volunteers consented to be treated for eight weeks with standardized outpatient individual counseling twice a week plus double-blind CBZ or inactive placebo. During the 8-week trial, both groups showed increased number of urine samples negative for cocaine, significantly (P < 0.01) decreased self-reported cocaine use (money spent and grams used), and decreased Beck Depression Inventory and Symptom Check List-90-Revised (SCL-90-R) total scores. However, there were no significant differences between CBZ and placebo. This study does not support the effectiveness of CBZ for outpatient treatment of cocaine dependence.

A model for pharmacological research-treatment of cocaine dependence

Major problems for research on pharmacological treatments for cocaine dependence are lack of comparability of results from different treatment research programs and poor validity and/or reliability of results. Double-blind, placebo-controlled, random assignment, experimental designs, using standard intake and assessment procedures help to reduce these problems. Cessation or reduction of drug use and/or craving, retention in treatment, and medical and psychosocial improvement are some of the outcome variables collected in treatment research programs. A model to be followed across different outpatient clinical trials for pharmacological treatment of cocaine dependence is presented here. This model represents an effort to standardize data collection to make results more valid and comparable.

Reduction of psychopathology among individuals participating in non-treatment drug abuse residential studies

The psychological repercussions in drug abusing individuals of their participation in non-treatment residential drug abuse research protocols have been uncertain. To study this, the average raw scores of the Symptom-Check List-90 Revised (SCL-90R) at the time of recruiting and discharge (40.2 +/- 15.6 days later) was studied at the Addiction Research Center of the National Institute on Drug Abuse (NIDA-ARC), in Baltimore, Maryland, in a sample of 233 drug abusers seeking no treatment. There was significant reduction in symptomatology (p < .01) between recruiting and discharge for Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Phobic Anxiety, Paranoid Ideation, Psychoticism, and Total Scores. These findings suggest that participation of drug abusers in non-treatment residential studies is safe and may improve their psychological status, which may be a therapeutic outcome of disengaging individuals from their drug environment and offering a safe and structured milieu.

A nutrition/health training program for Peace Corps volunteers

Nutrition and health education is a crucial component of the overall mission of the Peace Corps program. Individuals selected to work as Peace Corps volunteers need to be well prepared to perform this complex and challenging job in recipient countries. This article presents a model for a training program for Peace Corps trainees that was conducted over a 5-week period. The program was planned in accordance with some specific training guidelines that were provided by the Peace Corps. The trainees included nine women ranging in age from 22 to 61 years with diverse backgrounds; however, all had a BA/BS in a health-related discipline. Training curriculum included fundamental nutrition and health-related areas: basic nutrition, foods, clinical nutrition, maternal and child health, communicable diseases and sanitation, health strategies, and community development. Fifty percent of the curriculum was devoted to "hands-on" practical and clinical activities. Maternal and child health was emphasized in the training curriculum as this is an area of concern in all developing countries. The trainees were evaluated by weekly quizzes as well as completion of a special project involving applications of all their newly acquired skills. Implications of the training program are discussed.
