The impact of publicly funded managed care on adolescent substance abuse treatment outcomes

This study compares the 12-month changes in substance use following admission to substance abuse treatment in Massachusetts between adolescents enrolled in Medicaid managed care and other publicly funded adolescents. Two hundred and fifty-five adolescents were interviewed as they entered substance abuse treatment and at 6 and 12 month follow-ups. Medicaid enrollment data were used to determine the managed care enrollment status. One hundred forty two (56%) adolescents were in the managed care group and 113 (44%) comprise the comparison group. Substance use outcomes include a count of negative consequences of substance use, days of alcohol use, days of cannabis use, and days of any substance use in the previous 30 days. Repeated measures analysis of covariance (ANCOVA) was used to assess change with time of measurement and managed care status as main effects and the interaction of time and managed care included to measure differences between the groups over time. Although several changes across time were detected for all four outcomes, we found no evidence of an impact of managed care for any of the outcomes. The results of our study do not support the fears that behavioral managed care, by imposing limits on services provided, would substantially reduce the effectiveness of substance abuse treatment for adolescents. At the same time, the results do not support those who believe that the continuity of care and improved resource utilization claimed for managed care would improve outcomes.     

Public sector managed care: a comparative evaluation of substance abuse treatment in three counties

AIMS: A study of publicly funded substance abuse treatment systems compared MidState, a county that reorganized its treatment system using managed care principles, to two other California counties that took different approaches, NorthState and SouthState. It was hypothesized that MidState would have better outcomes due to its emphasis on quality of care. DESIGN: This natural experiment compared the 'experimental' county, MidState, to two 'control' counties, assessing client outcomes following treatment. Administrative and historical exigencies that may affect system differences were explored in interviews with treatment program managers and staff. SETTINGS: Comparison counties were selected using treatment system and county census data, maximizing similarities to enhance internal validity. PARTICIPANTS: Adult clients (n = 681) were interviewed when beginning treatment and 12 months later (81% response rate). In addition, 50 treatment program managers and staff members across the three counties were interviewed during the year of client recruitment. MEASUREMENTS: Client interviews assessed functioning in the seven Addiction Severity Index domains-alcohol, drug, psychiatric, legal, employment, medical and family/social. FINDINGS: Outcomes (differences between baseline and 12 month composite scores) did not differ between counties in six of seven domains; in the seventh, psychiatric functioning, SouthState had better outcomes than MidState. Staff interviews indicated generally similar treatment strategies across counties, with MidState supplying greater oversight and performance standards. CONCLUSIONS: Managed care in public sector treatment generally did not result in poorer outcomes. Future attention in MidState to the barriers to successful implementation of individualized treatment, and to dual diagnosis treatment, might bring more positive results.     

Processes and outcomes of substance abuse treatment between two programs for clients insured under managed care

The purpose of this research (N = 160) was to describe and compare substance abuse treatment in two programs under managed care: one residential (RT) and one outpatient (OP). Clients in both settings improved significantly from before to after treatment in relation to substance use and quality of life. However, intensity of treatment (hours of care/week) was much greater in RT and days of sobriety were significantly higher after treatment in RT than in OP (p = .04). Intensity was negatively related to incidents of substance use during treatment (SUdT), which predicted substance use after treatment; SUdT averaged .2 for RT, and 1.6 for OP (p = .0001). Importantly, treatment was completed by 74 patients (over 90%) from RT, with 8 dropping out, and 53 (almost 70%) of those in OP completed treatment while 25 dropped out. Intensity, as seen in the RT program, rather than duration, was more effective in substance use reduction and treatment completion.     

The primary care therapist and patient needs in substance abuse treatment

The author advocates that a clinician play the role of a primary care therapist (PCT) for substance abusers to assure that appropriate treatment interventions are provided to meet patient needs. In treating substance abusers, the PCT must be concerned about patients' needs for control, containment, contact, and comfort, especially initially, but also in an ongoing way. The PCT functions in direct, coordinating, and monitoring roles in order to optimally provide and combine psychotherapeutic and self-help elements.     

Factors predicting entry of injecting drug users into substance abuse treatment

A prospective study of 823 injecting drug users (IDUs) was made to identify baseline variables differentiating those who entered treatment during the study from those who did not enter. Variables independently associated with entering treatment in a multiple logistic regression model included (a) expressed desire for treatment, (b) being eligible for methadone maintenance, (c) two or more previous treatment admissions, (d) frequency of injection, (e) heroin use in the past 30 days, (e) being human immunodeficiency virus (HIV) positive, (f) giving money or drugs for sex, and (g) level of injection-related risk for HIV infection.

Female clients in substance abuse treatment

This paper reviews recent research on sex differences in the nature of alcohol and drug problems, use of treatment services, and the role of treatment and extratreatment factors in influencing these problems. Although patterns of use are different for men and women, responses to traditional treatment programs have not been different. Research suggests that programs providing ancillary services designed to meet the particular needs of women, such as child care, and those involving other family members and significant others hold the greatest promise for women with drug and alcohol problems.     

State substance abuse treatment gaps

This study estimated the adequacy of state substance abuse treatment rates relative to treatment needs. The investigators created composite drug and alcohol treatment need indexes from explicit-mention mortality and substance-defined arrest rates. The indexes were reliable and had evidence of construct validity, but alternative population-at-risk and survey-based need measures did not fair as well. States varied substantially in per capita alcohol and drug treatment needs, although the two did not correlate with each other. While the need indexes correlated significantly with state treatment rates, the adequacy of state treatment rates varied greatly. States with the largest treatment gaps were in the South, Southwest, and northern plains and mountain regions. The failure of the Block Grant formula to reflect the needs of rural states with high-risk minority populations may contribute to disparities in access to services.     

Impact of victimization on substance abuse treatment outcomes for adolescents in outpatient and residential substance abuse treatment

This paper considers whether victimization moderates adolescents' outcomes in substance abuse treatment. Adolescents (N=975) in outpatient and residential settings were assessed at intake, three, six, nine, and 12 months. Differential outcomes by gender and degree of victimization were analyzed. Dependent variables were marijuana use and substance-related problems. The residential sample reported higher baseline marijuana use and victimization. Both samples significantly reduced marijuana use and associated problems during treatment. Victimization was significantly related to more substance-related problems at intake and follow-up. More severe trauma histories in residential females were associated with significantly greater persistence in substance-related problems post-discharge.     

Co-ordination and continuity of care in substance abuse treatment. An evaluation study in Belgium

Considering the complexity of drug dependence and the multiplicity of services for substance abusers, co-ordination and continuity of care are important prerequisites for the quality of substance abuse treatment. However, several shortcomings concerning co-operation, communication and co-ordination have been reported in most European countries. In this study, different aspects of co-ordination and continuity (e.g. first contact, intake, referral, follow-up) have been studied among all services (n = 27) that are addressed by substance abusers in a clear-cut region in Belgium. Structured interviews with key informants show a lack of systematic communication between services and a lack of follow-up of clients. A study of 57 client records in 12 of these 27 centers illustrates that relatively little information is registered concerning the course of the treatment process and that only 10% of all client files contain a treatment plan. Following the introduction of a formalized plan that was regarded as a precondition for systematizing and optimizing communication between services, key informants considered the implementation of a model of case management as an appropriate way of improving co-ordination and continuity of care in this region.     

Effect of primary medical care on addiction and medical severity in substance abuse treatment programs

OBJECTIVE: To examine whether the availability of primary medical care on-site at addiction treatment programs or off-site by referral improves patients' addiction severity and medical outcomes, compared to programs that offer no primary care. DESIGN: Secondary analysis of a prospective cohort study of patients admitted to a purposive national sample of substance abuse treatment programs. SETTING: Substance abuse treatment programs in major U.S. metropolitan areas eligible for demonstration grant funding from the federal Substance Abuse and Mental Health Services Administration. RESPONDENTS: Administrators at 52 substance abuse treatment programs, and 2,878 of their patients who completed treatment intake, discharge, and follow-up interviews. MEASUREMENTS: Program administrators reported whether the program had primary medical care available on-site, only off-site, or not at all. Patients responded to multiple questions regarding their addiction and medical status in intake and 12-month follow-up interviews. These items were combined into multi-item composite scores of addiction and medical severity. The addiction severity score includes items measuring alcohol and drug use, employment, illegal activities, legal supervision, family and other social support, housing, physical conditions, and psychiatric status. The medical severity score includes measures of perceived health, functional limitations, and comorbid physical conditions. MAIN RESULTS: After controlling for treatment modality, geographic region, and multiple patient-level characteristics, patients who attended programs with on-site primary medical care experienced significantly less addiction severity at 12-month follow-up (regression coefficient, -25.9; 95% confidence interval [95% CI], -43.2 to -8.5), compared with patients who attended programs with no primary medical care. However, on-site care did not significantly influence medical severity at follow-up (coefficient, -0.28; 95% CI, -0.69 to 0.14). Referral to off-site primary care exerted no detectable effects on either addiction severity (coefficient, -9.0; 95% CI, -26.5 to 8.5) or medical severity (coefficient, -0.03; 95% CI, -0.37 to 0.44). CONCLUSIONS: On-site primary medical care improves substance abuse treatment patients' addiction-related outcomes, but not necessarily their health-related outcomes. Further study is needed to discern the mechanism through which on-site primary care might improve the addiction-related outcomes of substance abuse treatment.     

Recognition of alcoholism and substance abuse in primary care patients

Alcohol and other substance abuse are frequently seen in primary medical practice but are underdiagnosed. Forty-two (14%) of 294 adult primary care patients suffered from alcohol or other substance abuse, as diagnosed by a structured psychiatric interview. Primary care physicians identified 17 (40%) of these patients, as well as another patient identified during a six-month follow-up period, as having a substance abuse problem at initial clinical evaluation. Clinically identified substance abusers were older, more likely to be married, and more often used multiple drugs. They more frequently had antisocial personality disorders, while patients not clinically recognized were often depressed. Logistic regression analysis indicated that the presence of antisocial personality, the absence of a coexisting depressive disorder, and better social functioning scores were the factors most strongly associated with clinical recognition. The study suggests clinical judgment issues, which may be useful to physicians in training to improve their recognition and treatment of substance abuse disorders.     

Adolescents with co-occurring substance use and mental conditions in a private managed care health plan: prevalence, patient characteristics, and treatment initiation and engagement

This study examined the prevalence, patient characteristics, and treatment initiation and engagement of adolescents with co-occurring substance use (SU) and serious mental health (MH) diagnoses in a private, managed care health plan. We identified 2,005 adolescents aged 12-17, who received both SU and MH diagnoses within a 1-year window between 1/1/2000 and 12/31/2002; 57% were girls. Gender variations were found in diagnoses received and point of identification. Being dually diagnosed in specialty departments (rather than Primary Care and Emergency) and receiving both diagnoses within a shorter time period were associated with treatment initiation and engagement.     

Role of the primary care physician in problems of substance abuse.

Patients with substance abuse problems are common in general medical practice and include people of all ages and socioeconomic groups. Initial diagnosis and treatment of addiction problems are often done by the primary care practitioner before referral to a specialist. This article provides information to help in recognition of addiction, guidelines for treatment of intoxication and withdrawal of various drugs of abuse (such as opioids, sedative-hypnotics, stimulants, hallucinogens, and volatile inhalants), and techniques for brief intervention as well as long-term care of substance-abusing patients. The physician can be a powerful influence for getting the patient to accept treatment, especially when the physician is empathic without being judgmental. Addiction is a chronic disorder with remissions and relapses like any other chronic disease, so exacerbations should not be seen as failures but as time to intensify treatment. Patients with substance abuse problems can be frustrating to treat, but it can also be a rewarding experience when a physician helps a substance-abusing patient return to normal and productive functioning in society.     

Characteristics of opinion leaders in substance abuse treatment agencies

OBJECTIVE: This study was part of a larger effort to test the effectiveness of technology transfer approaches related to evidence-based treatment of co-occurring substance abuse and mental health disorders. Specifically, this study examined characteristics of "opinion leaders" as technology transfer agents. METHOD: A network analysis was conducted within four large substance abuse treatment agencies to identify individuals that other counselors sought out for consultation on co-occurring issues. The identified opinion leaders were then compared with other counselors on demographic variables, education and experience, and attitudes and knowledge about working with individuals with co-occurring disorders. RESULTS: The analyses demonstrate that opinion leaders differed from other counselors in competency-related characteristics including more postgraduate education, relevant professional credentials, and years of experience in mental health treatment. They also had greater knowledge of the dynamics and treatment of co-occurring disorders as well as a greater willingness and confidence in working with such clients. CONCLUSION: These results suggest that opinion leaders are used within agencies for information and consultation regarding treatment issues. Therefore, opinion leaders may provide an important vehicle for dissemination and adoption of evidence-based treatment practices in community treatment settings.     

Inpatient substance abuse care and the outcome of subsequent community residential and outpatient care

Aim. To compare participation in treatment and 1-year substance use, symptom and functioning outcomes between patients with substance use disorders who did versus those who did not have an episode of inpatient care immediately prior to an episode of community residential and outpatient mental health care. Design. Two matched groups of 257 patients each with substance use disorders were assessed at entry to and discharge from a community residential facility (CRF) and at a 1-year follow-up. Findings. Patients in the two treatment groups received a comparable amount of CRF and outpatient mental health care. Nevertheless, patients who had prior inpatient care were more likely to be employed at 1-year follow-up. In addition, when they entered CRF care directly, patients with co-morbid psychiatric disorders were more likely to continue use of alcohol and drugs in the CRF and less likely to complete the program. These patients also experienced more distress and psychiatric symptoms, and were less likely to be employed at the 1-year follow-up. Conclusions. Among patients who seek treatment at Department of Veterans Affairs (VA) facilities, those who have both substance use and psychiatric disorders and enter CRF care directly have somewhat worse outcomes than those who have an immediately prior episode of inpatient care.
