Managed care penetration in outpatient substance abuse treatment units

Assessing the Service Linkages of Substance Abuse Agencies with Mental Health and Primary Care Organizations

Fragmentation of substance abuse treatment represents a major barrier to effective treatment for individuals with cooccurring substance abuse and mental and physical health disorders. Linkages of substance abuse treatment organizations with primary care and mental health agencies are widely considered to be a feasible way to integrate services. In this study, we analyzed information collected from a national sample of 62 outpatient substance abuse treatment units (OSATs) to understand the extent of services linkages in these organizations and to identify facilitators and barriers to service linkages. Results showed that OSATs had limited service linkages with primary care and mental health providers. The cited barriers to linkages included clients' financial problems, managed care restrictions, and limited organizational capacity. Onsite service provision was implemented in some OSATs. The pattern of service linkages in OSATs appeared to reflect the health needs of substance abuse clients.

Organizational- and individual-level correlates of posttreatment substance use: a multilevel analysis

In addressing the need to study the effects of organizational factors on individual-level treatment outcomes, this study used hierarchical models to examine the organizational- and individual-level correlates of posttreatment substance use. Risk for posttreatment use varied significantly across organizations. Factors in the external institutional environment of facilities significantly influenced risk for use: managed care regulation increased the risk, whereas Joint Commission on the Accreditation of Healthcare Organizations accreditation decreased it (p < .01 for both). On the individual level, longer treatment episodes and treatment completion reduced the risk (p < .01 for both) after controlling for client characteristics. The benefits of length of stay in treatment were modified by elements of the external institutional environment and organizational treatment technology. The ameliorative effects of prolonged treatment were reduced by higher levels of managed care regulation, organizational monitoring, caseload size (p < .01 for all), and proportion of degreed staff (p < .05). The results highlight the influence of organizational factors on posttreatment use.

The role of organization and management in substance abuse treatment: Review and roadmap

To develop an understanding as to why there exists a seemingly wide gap between research and practice in the field of substance abuse treatment and, more important, to understand how this gap can be closed, researchers have focused their attention on the role of organizational and management factors in the delivery of treatment services. This article's overarching goal is to stimulate research and interventions that focus on these factors so as to improve the standards and outcomes of care in substance abuse treatment. Part 1 introduces the key assumptions and perspectives that guide organization and management research. Part 2 selectively reviews empirical studies that examine relationships between treatment programs' use of research-based treatment practices and organization and management factors. The article concludes with a discussion of the next important steps for research and policy.

Organization and financing of alcohol and substance abuse programs for American Indians and Alaska Natives

OBJECTIVES

Although American Indians and Alaska Natives have high rates of substance abuse, few data about treatment services for this population are available. We used national data from 1997-2002 to describe recent trends in organizational and financial arrangements.

METHODS

Using data from the Indian Health Service (IHS), the Substance Abuse and Mental Health Services Administration, the National Institute on Alcohol Abuse and Alcoholism, the Henry J. Kaiser Family Foundation, and the Census Bureau, we estimated the number of American Indians served by substance abuse treatment programs that apparently are unaffiliated with either the IHS or tribal governments. We compared expected and observed IHS expenditures.

RESULTS

Half of the American Indians and Alaska Natives treated for substance abuse were served by programs (chiefly in urban areas) apparently unaffiliated with the IHS or tribal governments. IHS substance abuse expenditures were roughly what we expected. Medicaid participation by tribal programs was not universal.

CONCLUSIONS

Many Native people with substance abuse problems are served by programs unaffiliated with the IHS. Medicaid may be key to expanding needed resources.

Factors associated with interorganizational relationships among outpatient drug treatment organizations 1990-2000

OBJECTIVE

To identify the factors associated with drug abuse treatment center participation in interorganizational relationships (IORs).

DATA SOURCES

Three nationally representative samples of outpatient drug abuse treatment units surveyed in 1990, 1995, and 1999/2000 as part of the National Drug Abuse Treatment System Survey (NDATSS), stratified by public/private status, treatment modality (methadone or nonmethadone), and organizational affiliation.

STUDY DESIGN

Probit analyses on 647 lagged treatment center-year observations from the years 1990 to 1995 with outcomes in 1995 and 2000, respectively. Standard errors were adjusted for clustering of center-year observations within centers.

PRINCIPAL FINDINGS

Centers with greater motivation to form IORs (e.g., as a result of client diversity or government revenue) were more likely to do so, as were centers with greater opportunities to form IORs (e.g., centers whose directors participated in policy making).

CONCLUSIONS

Both motivating and enabling factors promoted the formation of IORs by drug abuse treatment centers. Managed care also played a distinct role, in this case appearing to undermine interorganizational cooperation. Because IORs can improve access to care and quality, policy makers should consider using both incentives and support such as management training to promote IOR formation.

Managed Care's Dual Impact on Outpatient Substance Abuse Treatment: Methadone Maintenance vs. Drug Free

The number and type of services offered at substance abuse treatment (SAT) facilities are important aspects of the quality of care. Managed care (MC) is a growing presence in SAT and has been shown to affect the provision of treatment. We expand on earlier work and examine the impact of managed care on the number and type of services offered by methadone maintenance (MM) and drug-free (DF) outpatient treatment facilities. We use the econometric technique of instrumental variables to address the issue of endogeneity of MC and service offerings, thereby allowing a causal interpretation of results. Using data from the 2000 National Survey of Substance Abuse Treatment Services, we find that MC significantly increases the total number of services offered in MM outpatient facilities by four, yet decreases the number by two in DF outpatient facilities. We also show how the impact on specific services differs by modality and provide explanations for our findings.

Adoption of naltrexone to treat alcohol dependence

Three surveys (1997, 1999, and 2001) of outpatient substance abuse treatment centers in Connecticut, Massachusetts, Rhode Island, Maine, Vermont, and New Hampshire examined organizational characteristics that influenced the adoption of naltrexone. Structural equation modeling with manifest variables assessed predictors related to the use of naltrexone. Use of naltrexone increased over time from 14% in 1997 to 25% in 2001. In 1997, programs funded by managed care were more likely, and clinics that provided only substance abuse services were less likely to use psychiatric medication and naltrexone. In subsequent years, counselor education level and organization size also influenced use of naltrexone.

The administrative control system of substance abuse managed care

OBJECTIVE

This article searches for the dimensions of the administrative structures in outpatient substance abuse managed care that control the behavior of agency providers. It also ascertains how these dimensions, and several financial mechanisms, affect key aspects of the providers services: the average number of sessions of care that are delivered, the rate of completion of care, and the (estimated) rate at which clients control their substance use.

DATA SOURCES

The data were collected in 1999 for this investigation.

STUDY DESIGN

These data come from a nationally representative, cross-sectional sample of individual contracts between outpatient drug treatment providers and the Behavioral Health Managed Care Organizations (BHMCOs) that are empowered to regulate the delivery of services. Provider responses are analyzed here.

DATA COLLECTION METHODS

Factor analyses at a contract level examine the structural dimensions of the control system. Multivariate analyses at the same level rely on generalized linear models to predict the dependent variables by the structural dimensions and financial mechanisms.

FINDINGS

The factor analyses suggest that there are six multiple variable structural dimensions. The multivariate analyses suggest that the dimension that mandates follow-up of discharged clients tends to relate to more sessions of care and perhaps a higher rate of service completion. Most other dimensions are found to relate to fewer sessions of care, lower rates of service completion, or lower rates of control of substance abuse. No structural dimension relates to all dependent variables. Financial mechanisms evince varying relations to the sessions of care. They rarely relate to the other dependent variables.

CONCLUSION

The results generally suggest that providers, payers, or policymakers might affect service provision by selecting BHMCOs that stress particular structural dimensions and financial mechanisms. However, managed care contracts most heavily rely on structural dimensions that restrict treatment sessions and fail to predict superior client outcomes.

The impact of managed care on substance abuse treatment services

OBJECTIVE

To examine the impact of managed care on the number and types of services offered by substance abuse treatment (SAT) facilities. Both the number and types of services offered are important factors to analyze, as research shows that a broad range of services increases treatment effectiveness.

DATA SOURCES

The 2000 National Survey of Substance Abuse Treatment Services (NSSATS), which is designed to collect data on service offerings and other characteristics of SAT facilities in the United States. These data are merged with data from the 2002 Area Resource File (ARF), a county-specific database containing information on population and managed care activity. We use data on 10,513 facilities, virtually a census of all SAT facilities.

STUDY DESIGN

We estimate the impact of managed care (MC) on the number and types of services offered by SAT facilities using instrumental variables (IV) techniques that account for possible endogeneity between facilities' involvement in MC and service offerings. Due to limitations of the NSSATS data, MC and specific services are modeled as binary variables.

PRINCIPAL FINDINGS

We find that managed care causes SAT facilities to offer, on average, approximately two fewer services. This effect is concentrated primarily in medical testing services (i.e., tests for TB, HIV/AIDs, and STDs). We also find that MC increases the likelihood of offering substance abuse assessment and relapse prevention groups, but decreases the likelihood of offering outcome follow-up.

CONCLUSION

Our findings raise policy concerns that managed care may reduce treatment effectiveness by limiting the range of services offered to meet patient needs. Further, reduced onsite medical testing may contribute to the spread of infectious diseases that pose important public health concerns.

Managed behavioral health care: an instrument to characterize critical elements of public sector programs

OBJECTIVE

To develop an instrument to characterize public sector managed behavioral health care arrangements to capture key differences between managed and "unmanaged" care and among managed care arrangements.

STUDY DESIGN

The instrument was developed by a multi-institutional group of collaborators with participation of an expert panel. Included are six domains predicted to have an impact on access, service utilization, costs, and quality. The domains are: characteristics of the managed care plan, enrolled population, benefit design, payment and risk arrangements, composition of provider networks, and accountability. Data are collected at three levels: managed care organization, subcontractor, and network of service providers.

DATA COLLECTION METHODS

Data are collected through contract abstraction and key informant interviews. A multilevel coding scheme is used to organize the data into a matrix along key domains, which is then reviewed and verified by the key informants.

PRINCIPAL FINDINGS

This instrument can usefully differentiate between and among Medicaid fee-for-service programs and Medicaid managed care plans along key domains of interest. Beyond documenting basic features of the plans and providing contextual information, these data will support the refinement and testing of hypotheses about the impact of public sector managed care on access, quality, costs, and outcomes of care.

CONCLUSIONS

If managed behavioral health care research is to advance beyond simple case study comparisons, a well-conceptualized set of instruments is necessary.

Effects of managed care on programs and practices for the treatment of alcohol and drug dependence

Managed care is affecting the organization and financing of treatment services for alcohol and drug dependence. This paper examines the effects of managed care on program operations including the use of clinical protocols, the administrative burden, information systems, staffing, and program consolidation. It also reviews the effects of managed care on system performance related to employer-sponsored health plans, state employee health plans, and Medicaid and other public plans. Our review of managed care's influences on the alcohol and drug abuse treatment system finds evidence of systemic reductions in access to inpatient care and increased reliance on outpatient services. Moreover, although analyses of behavioral health carve-outs often suggest increases in the use of outpatient care, evaluations of substance abuse claims report reductions in ambulatory utilization for the treatment of alcohol and drug dependence.

Using cost and financing instruments for economic evaluation of substance abuse treatment services

Standardized economic evaluation instruments are an important tool in the analysis of change and performance of addiction treatment. Nevertheless, compared to other health care sectors, economic evaluation of addiction treatment is still rare. The present paper proposes two comprehensive economic evaluation instruments that are methodologically sound and that meet the objectives of comprehensiveness, standardization, and comparability. The Drug Abuse Treatment Cost Analysis Program (DATCAP) can be used to estimate the economic cost of treatment services; the Drug Abuse Treatment Financing Analysis Program (DATFin) is a companion instrument and analyzes the complexity and change of treatment financing. This paper outlines the contents of each instrument and, for illustrative purposes, presents results from several case studies. Suggestions for updates and enhancements for each instrument are also discussed.

Selecting data sources for substance abuse services research

In this article we discuss the strengths and weaknesses of using different types of data sources for alcohol and drug abuse services research. To do this, we describe four types of data sources used in substance abuse services research: surveys of organizations, medical records, claim and encounter data and program-level administrative data. For each, we outline where to obtain data, how each type has been used, and the advantages and challenges. This overview should allow investigators to think more critically about the datasets they now use; providers to understand the types of data sources most appropriate for specific research questions so as to participate more fully in research; and policy makers to interpret correctly results based on different types of data. Moreover, it should foster better communication among these stakeholders in collaborative projects to improve the effectiveness of services for people with addictions.

Managed care and outpatient substance abuse treatment intensity

This study examines the extent to which managed care behavioral controls are associated with treatment intensity in outpatient substance abuse treatment facilities. Data are from the 1995 National Drug Abuse Treatment System Survey, a nationally representative survey that includes over 600 provider organizations with a response rate of 86%. Treatment intensity is measured in three ways: (1) the number of months clients spend in outpatient drug treatment, (2) the number of individual treatment sessions clients receive over the course of treatment, and (3) the number of group treatment sessions clients receive over the course of treatment. After accounting for selection bias and controlling for market, organization, and client characteristics, there is no significant relationship between the scope of managed care oversight and treatment intensity. However, the stringency of managed care oversight activities is negatively associated with the number of individual and group treatment sessions received over the course of treatment.
