Review of integrated mental health and substance abuse treatment for patients with dual disorders

Dual Diagnosis Motivational Interviewing: a modification of Motivational Interviewing for substance-abusing patients with psychotic disorders

Motivational Interviewing (MI) is a brief treatment approach for helping patients develop intrinsic motivation to change addictive behaviors. While initially developed to target primary substance using populations, professionals are increasingly recognizing the promise this approach has for addressing the motivational dilemmas faced by patients who have co-occurring psychiatric and psychoactive substance use disorders. Unfortunately, this recognition has not lead to a clear explication of how MI might be adopted for specific diagnostic populations of dually diagnosed patients. In this article we describe how we have applied the principles and practices of MI to patients who have psychotic disorders and co-occurring drug or alcohol use problems. Specifically, we provide two supplemental guidelines to augment basic MI principles (adopting an integrated dual diagnosis approach, accommodating cognitive impairments and disordered thinking). We present recommended modifications to primary MI skill sets (simplifying open-ended questions, refining reflective listening skills, heightening emphasis on affirmation, integrating psychiatric issues into personalized feedback and decisional balance matrices). Finally, we highlight other clinical considerations (handling psychotic exacerbation and crisis events, recommended professional qualifications) when using MI with psychotic disordered dually diagnosed patients.

Improving service delivery to the dually diagnosed in Los Angeles County

Service delivery to dually diagnosed individuals remains problematic in many communities because of entrenched administrative structures that maintain the separation of mental health and substance abuse treatment systems. This article describes efforts to improve service delivery to dually diagnosed individuals in Los Angeles County by increasing communication, coordination, and collaboration across the two treatment systems. Findings are presented on the relationships among program models of service delivery, treatment orientations of programs, and interactions with other service providers to the dually diagnosed. Results showed that drug treatment programs that adhered more closely to an integrated model of service delivery received more patient referrals from case management outreach teams and that programs with a stronger counseling approach to treatment had more linkages with other service providers. Knowledge gained from research on these differing models of service delivery can be combined with new clinical advances to improve service delivery to the dually diagnosed.

Substance misuse in patients with schizophrenia: epidemiology and management

Substance misuse in individuals with schizophrenia is very common, especially in young men, in communities where use is frequent and in people receiving inpatient treatment. Problematic use occurs at very low intake levels, so that most affected people are not physically dependent (with the exception of nicotine). People with schizophrenia and substance misuse have poorer symptomatic and functional outcomes than those with schizophrenia alone. Unless there is routine screening, substance misuse is often missed in assessments. Service systems tend to be separated, with poor inter-communication, and affected patients are often excluded from services because of their comorbidity. However, effective management of these disorders requires a fully integrated approach because of the close inter-relationship of the disorders. Use of atypical antipsychotics may be especially important in this population because of growing evidence (especially on clozapine and risperidone) that nicotine smoking, alcohol misuse and possibly some other substance misuse is reduced. Several pharmacotherapies for substance misuse can be used safely in people with schizophrenia, but the evidence base is small and guidelines for their use are necessarily derived from experience in the general population.

A family intervention program for dual disorders

OBJECTIVE

To provide a rationale for working with families of clients with psychiatric and substance use disorder, and to describe a new program, family intervention for dual disorders (FIDD).

METHOD

We developed and manualized the FIDD program, which includes both single-family and multiple-family group formats. We trained several clinicians at a local mental health center in the model and conducted a small pilot study.

RESULTS

Clinicians were able to implement the program, and to successfully engage families in treatment. Most clients demonstrated significant improvements in substance abuse over one to two years of treatment.

CONCLUSIONS

The FIDD program is feasible and appears to promote collaboration between families and professionals, thereby improving the course of dual disorders. Controlled research is underway to evaluate the effects of the FIDD program on client and family outcomes.

Psychosocial aspects of substance abuse by clients with severe mental illness

As the literature on co-occurring substance abuse in persons with severe mental illnesses has evolved, emphasis on biologic and pharmacologic factors has diverted attention from important psychosocial issues. The authors review recent research showing that a) psychosocial risk factors may explain consistently high rates of substance abuse by these persons, b) substance abuse is for most clients a socio-environmental phenomenon embedded in interpersonal activities, and c) both natural recovery processes and effective treatments rely on developing new relationships, activities, coping strategies, and identities. Thus, psychosocial issues are critical in our attempts to understand and address substance abuse in this population.

Central New York Psychiatric Center: an approach to the treatment of co-occurring disorders in the New York State correctional mental health system

Central New York Psychiatric Center operates a maximum security inpatient treatment hospital and outpatient mental health services for all of the 72 New York State prisons. In this article prevalence data, patient characteristics, and interventions offered to inmates diagnosed with co-occurring mental illness and substance abuse disorders in the New York State prison system are reviewed and discussed. Available interventions have resulted from the close collaboration of the State Department of Correctional Services and State Office of Mental Health. Aspects of current programs and plans for future service developments are discussed along with implications for the treatment of an offender population diagnosed with a co-occurring disorder.

Motivational intervention as applied to systems change: the case of dual diagnosis

The concept of motivational interviewing is based on helping individual clients build and sustain a commitment to reach and carry out a decision to change. In this paper, the motivational interviewing model is applied to systems change. Different stages of involvement and readiness to change are identified within systems which closely resemble those found in individuals. When applied to a system, we call this process "Motivational Intervention." In this paper, the motivational intervention model is applied to a psychiatric system of health care delivery where large numbers of psychiatric patients are found to also have substance use-related problems. Several Italian health districts invited the authors to present a series of lectures and workshops in order to facilitate the incorporation of substance user treatment into existing psychiatric services. Using the motivational intervention model to determine where the system was in the process of change, we then identified the tasks necessary to facilitate further change.

Managing comorbid schizophrenia and substance abuse

Effective treatments for co-occurring schizophrenia and substance abuse have emerged over the past 15 years. They involve integration and melding of mental health and substance abuse treatments, helping people to acquire the skills and supports they need to manage both illnesses and to pursue functional goals, and a comprehensive, long-term approach to recovery. Further research is needed to refine specific interventions and to improve knowledge regarding implementing integrated treatment settings in routine mental health programs.

Contingency management in group treatment: a demonstration project in an HIV drop-in center

This study describes a contingency management intervention applied in group treatment. In an HIV drop-in center, groups were held on Tuesdays and Thursdays for 35 weeks. An ABB'CA design was used, in which reinforcers were available in non-A phases. In the initial B phase, reinforcers were available only on Tuesdays, and they switched to Thursdays in the B' and C phases. The reinforcer was a drawing that was associated with the possibility of winning a prize. Reinforcers were provided for attending group and completing steps related to treatment goals. The number of drawings escalated with weeks of consecutive attendance and activity completion in the B phases; in the C phase, a fixed number of draws were provided. Overall, the procedure increased attendance, with an average of 0.7 clients (range 0-4) per session in the initial baseline phase to an average of seven clients (range 2-12) during reinforcement phases. The percentage of activities completed also rose from 25% during baseline to 65% during reinforcement phases. These data suggest the feasibility of a group-based contingency management intervention.

Treating substance abuse in schizophrenia. An initial report

Schizophrenia patients show alarmingly high rates of substance use disorders. These patients experience neurocognitive and social deficits that make it difficult for them to benefit from effective treatment strategies designed for less-impaired populations. Previously, we described Behavioral Treatment for Substance Abuse in Schizophrenia and discussed how the program was adapted for this population. Here we provide an update of BTSAS, discuss our clinical experience running the intervention, and review how it has changed over five years of development. We present attendance, participation, and substance use data on patients who consented to attend (n = 42), completed (n=14), and dropped out (n = 14) of the program. Outcome data are provided for 14 patients, and comparisons are made between good (n = 5; > or = 67% of urine tests clean from a goal drug over 6 months) and poor (n = 9; < or = 66% of urine tests clean) progress patients. Implications for the treatment are discussed.

Service use and cost by mentally ill chemical abusers: differences by retention in a therapeutic community

PURPOSE

Earlier research estimated the incremental costs and outcomes of a modified therapeutic community (modified TC) for mentally ill chemical abusers (MICAs) relative to a treatment-as-usual (TAU) control group. The present study extended the cost analysis by disaggregating the modified TC group into clients who completed the program (completers) and clients who dropped out (separaters).

METHODS

Bivariate and multivariate analyses were conducted to estimate differences in treatment and other service costs among completers, separaters, and TAU. Subjects were sequentially assigned to the modified TC (n = 171) or TAU (n = 47), and the analysis period covered 12 months post-baseline. Using a standardized instrument to collect resource use and cost data, the estimated weekly cost per client in the modified TC was $554, with completers showing a larger average cost of treatment ($27,595) than separaters ($9,986).

RESULTS

The average TAU subject had a much higher cost for other (non-modified TC) services ($29,795) relative to separaters ($22,048) or completers ($1,986). These findings suggest that, from baseline to the 12-month follow-up, the total cost of modified TC treatment and other services for completers may be slightly lower than the total cost for separaters or TAU subjects. Since the modified TC group had better outcomes than the TAU group, and the completers had better outcomes than the separaters, the modified TC program could be an effective mechanism to reduce the costs of service utilization as well as improve clinical outcomes.

IMPLICATIONS

This detailed investigation into service utilization and cost provides policy-makers and program directors with valuable information regarding potentially cost-effective interventions and further underscores the importance of retention in treatment for this vulnerable population.

Integrating services for schizophrenia and substance abuse

Over the past decade, several studies have attempted to determine whether integrating psychiatric and substance abuse treatment leads to better outcome for patients with comorbid schizophrenia and substance use disorders. A recent (1999) Cochrane Review (1) analyzed the effectiveness of prospective randomized studies of integrated treatment approaches, and concluded that there was no clear evidence for superiority of integrated treatment. This paper describes one such integrated treatment approach, in Beth Israel Medical Center's COPAD (Combined Psychiatric and Addictive Disorders) program. We summarize findings from an initial outcome study and a recent replication study; and describe clinical and research issues relevant to this population. Our data suggests the benefits of integrated treatment for patients with addictive disorders and schizophrenia, at least with regard to treatment retention. Clinical issues for such patients include identification of patients at risk, proper assessment and treatment planning, decision-making about mainstreaming vs. referral to specialized programs, and the importance of initial engagement and ongoing reengagement in successful treatment.

Prevalence of HIV, hepatitis B, and hepatitis C in people with severe mental illness

OBJECTIVES

This study assessed seroprevalence rates of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) among individuals with severe mental illness.

METHODS

Participants (n = 931) were patients undergoing inpatient or outpatient treatment in Connecticut, Maryland, New Hampshire, or North Carolina.

RESULTS

The prevalence of HIV infection in this sample (3.1%) was approximately 8 times the estimated US population rate but lower than rates reported in previous studies of people with severe mental illness. Prevalence rates of HBV (23.4%) and HCV (19.6%) were approximately 5 and 11 times the overall estimated population rates for these infections, respectively.

CONCLUSIONS

Elevated rates of HIV, HBV, and HCV were found. Of particular concern are the high rates of HCV infection, which are frequently undetected. Individuals with HCV infection commonly fail to receive appropriate treatment to limit liver damage and unknowingly may be a source of infection to others.

Social costs of untreated opioid dependence

Using cost-of-illness methodology applied to a comprehensive survey of 114 daily opiate users not currently in or seeking treatment for their addiction, we estimated the 1996 social costs of untreated opioid dependence in Toronto (Ontario, Canada). The survey collected data on social and demographic characteristics, drug use history, physical and mental health status, the use of health care and substance treatment services, drug use modality and sex-related risks of infectious diseases, sources of income, as well as criminality and involvement with the law enforcement system. The annual social cost generated by this sample, calculated at Canadian $5.086 million, is explained mostly by crime victimization (44.6%) and law enforcement (42.4%), followed by productivity losses (7.0%) and the utilization of health care (6.1%). Applying the $13,100 cost to the estimated 8,000 to 13,000 users and 2.456 million residents living in Toronto yields a range of social cost between $43 and $69 per capita.

An ethnographic study of the longitudinal course of substance abuse among people with severe mental illness

A two-year ethnography conducted among 16 dually diagnosed clients yielded two longitudinal findings. First, four "positive quality of life" factors were strongly correlated with clients' efforts to cease using addictive substances: (1) regular engagement in an enjoyable activity; (2) decent, stable housing; (3) a loving relationship with someone sober who accepts the person's mental illness; and (4) a positive, valued relationship with a mental health professional. Second, the study revealed that five "negative background factors" in participants' childhood homes were predictive of long-term continuation of substance use: (1) substance abuse in childhood home, (2) childhood household in dire poverty, (3) "non-functional" household members, (4) reporting of abuse imputed to care-givers, and (5) serious mental illness in household. The implications of these findings for treatment are discussed.

Mental health versus substance abuse treatment programs for dually diagnosed patients

The aim of this study was to assess the similarities and differences of patients with co-existing psychiatric and substance use disorders attending treatment in either a mental health setting or a substance abuse treatment setting. A total of 129 patients were assessed, including 65 individuals from the substance abuse treatment center and 64 individuals from the mental health program. Treatment records were reviewed for diagnoses and sociodemographic data. While the two groups were highly similar with regard to age and ethnicity, there were significant differences in psychiatric profile, with the substance abuse treatment group having less severe diagnoses and no patients with schizophrenia, while the mental health treatment group had a majority of patients with schizophrenia. Other differences in the two groups, such as marital and parental status, disability status, and medical problems appeared to be directly linked with the aforementioned diagnostic profile. These data suggest important differences in characteristics of patients with comorbid disorders that appear to be dependent on the type of treatment program they attend. For the most effective management, integrated treatment programs should be aware of these differences and tailor service provision accordingly.

Co-occurring mental and substance use disorders: promising approaches and research issues

This paper surveys the mental health and drug user treatment literature, identifying promising approaches and research issues in the treatment of co-occurring mental illness and substance use disorders. The prevalence and classification of co-occurring disorders are briefly reviewed, and selected treatment models currently in use are described. Three models are cited as representing particularly promising approaches--comprehensive integrated treatment, assertive community treatment, and the modified therapeutic community--and best practices are summarized. This paper proposes a research agenda focused on relevant emerging treatment issues.

Conceptualizing and assessing treatment structure and process in community-based drug dependency treatment programs

Having established the effectiveness of drug dependency treatment, the next generation of research will necessitate a focus on treatment structure and process and the systems within which programs operate. As a foundation for a process conceptualization, we constructed a grounded theory definition of treatment consisting of core elements and related comprehensive services. We then presented the multilevel conceptual framework that guided the Drug Abuse Treatment Outcome Study (DATOS) treatment structure and process study design and instrumentation, anchored by supporting empirical literature. The framework emphasizes seven critical levels of process measurement that future research should consider in order to avoid potential spurious findings.

Severely and persistently mentally ill substance abusers: clinical and policy issues

Communities that are struggling to provide effective treatment for the challenging population of severely mentally ill clients who use alcohol and drugs have a growing research base on which to make policy decisions. Integrating outpatient treatment for mental health and addictive disorders appears to be more effective than treatment in two separate systems. Integrated treatment at a single site allows for individualizing treatment priorities without fragmenting care. Harm reduction approaches provide a low threshold entry, which can be followed by interventions to enhance motivation. Managing patient benefits to discourage drug use reduces the likelihood of their becoming homeless, hospitalized or incarcerated. Inadequate treatment capacity plays a large role in the growing number of disturbed clients who end up in the criminal justice system. Effective community treatment requires vigorous collaboration between care providers. Ultimately, professional training programs need to produce clinicians who are competent and comfortable addressing alcohol and other drug use to implement effective treatment systems.

Evidence-based treatment of schizophrenia

People with schizophrenia can be helped greatly with pharmacologic and psychosocial interventions that are known to be effective. Several interventions are now supported by research: use of medications following specific guidelines, training in illness self-management, case management based on principles of assertive community treatment, family psychoeducation, supported employment, and integrated substance abuse treatment. However, few patients actually receive these evidence-based interventions because they are not provided in routine mental health settings. Therefore, implementing effective treatments in mental health treatment programs is a critical challenge for the field. We review the six areas of evidence-based treatment of schizophrenia, as well as knowledge regarding implementation of mental health programs in routine practice settings.

Treating substance abuse in the context of severe and persistent mental illness: clinicians' perspectives

Patients with comorbid substance use and major mental disorders are treated frequently in the mental health system. Treatment models relevant for this subset of patients have emerged in recent years, however, few have been validated empirically and so relatively few sites benefit from this treatment development activity. Important additional sources of information about good treatment practices are the clinicians who have adopted the treatment of patients with dual disorders as a specialty. We conducted four focus groups (N = 12) with clinicians who were nominated by their peers as experienced and/or expert in treating persons with comorbid substance use and psychiatric disorders. Discussions followed a four-part outline that included (a) general questions about training and experience with the population, (b) preferred treatment methods, (c) motivational issues, and (d) recommendations to the field. Participants were trained in a variety of mental health disciplines and pursued substance abuse treatment credentials or other educational experiences outside of their primary training programs. Their treatment approaches emphasized psychoeducation, a good therapeutic relationship, and the need to be flexible regarding methods and goals. Abstinence was the preferred goal among most clinicians; even so, they expressed a pragmatic flexibility and other views consistent with the principles of harm reduction. Clinicians tended to respond to patients' ambivalent motivational states by addressing the consequences of behaviors in a nonconfrontive style; they also made use of positive incentives and external support. A number of recommendations were made to improve treatment, including greater institutional and programmatic support for the unique needs of this population.

Longitudinal effects of integrated treatment on alcohol use for persons with serious mental illness and substance use disorders

A randomized experimental design was used to assign participants to an integrated mental health and substance use treatment program or to standard hospital treatment. A multilevel, nonlinear model was used to estimate hospital treatment effects on days of alcohol use for persons with serious mental illness and substance use disorders over 18 months. The integrated treatment program had a significant effect on the rate of alcohol use at 2 months postdischarge, reducing the rate of use by 54%. Motivation for sobriety at hospital discharge, posttreatment self-help attendance, and social support for sobriety were also found to reduce the rate of use during the follow-up period. Implications for mental health treatment and aftercare support are discussed.

Modified therapeutic community for homeless mentally ill chemical abusers: treatment outcomes

This study compared homeless mentally ill chemical abuser (MICA) clients (n = 342), male and female, sequentially assigned to either of two modified therapeutic community programs (TC1 and TC2) and to a treatment-as-usual (TAU) control group. Follow-up interviews were obtained at 12 months postbaseline and at time F (on average more than 2 years postbaseline) on a retrieved sample of 232 (68%) clients and 281 (82%) clients, respectively. Outcome measures assessed five domains: drug use, crime, HIV risk behavior, psychological symptoms, and employment. Individuals in both modified TC groups showed significantly greater behavioral improvement than TAU at 12 months and time F, and the modified TC2, with lower demands and more staff guidance, was superior to modified TC1. Completers of both TC programs showed significantly greater improvement than dropouts and a subgroup of TAU clients with high exposure (i.e., more than 8 months) to other treatment protocols. The present findings support the effectiveness and longer term stability of effects of a modified TC program for treating homeless MICA clients.

An Integrated Approach for Dually Diagnosed Patients in a Substance Abuse Treatment Program: Case Presentation

Patients with co-occurring psychiatric and substance use disorders experience worse social and clinical outcomes and are in need of adequate and simultaneous treatment for both disorders. The case presented illustrates the diversity of psychosocial, health, and behavioral problems and the complexity of treatment of a dually diagnosed patient. The authors discuss the benefits of using an integrated approach in an addiction treatment setting. The authors also review the importance of an integrated treatment model for populations with inadequate health care resources who are at high risk for medical and psychiatric complications.

Contrasting views and experiences of health professionals on the management of comorbid substance misuse and mental disorders

OBJECTIVES

To determine opinions and experiences of health professionals concerning the management of people with comorbid substance misuse and mental health disorders.

METHOD

We conducted a survey of staff from mental health services and alcohol and drug services across Queensland. Survey items on problems and potential solutions had been generated by focus groups.

RESULTS

We analysed responses from 112 staff of alcohol and drug services and 380 mental health staff, representing a return of 79% and 42% respectively of the distributed surveys. One or more issues presented a substantial clinical management problem for 98% of respondents. Needs for increased facilities or services for dual disorder clients figured prominently. These included accommodation or respite care, work and rehabilitation programs, and support groups and resource materials for families. Needs for adolescent dual diagnosis services and after-hours alcohol and drug consultations were also reported. Each of these issues raised substantial problems for over 70% of staff. Another set of problems involved coordination of client care across mental health and alcohol and drug services, including disputes over duty of care. Difficulties with intersectoral liaison were more pronounced for alcohol and drug staff than for mental health. A majority of survey respondents identified 13 solutions as practical. These included routine screening for dual diagnosis at intake, and a range of proposals for closer intersectoral communication such as exchanging client information, developing shared treatment plans, conducting joint case conferences and offering consultation facilities.

CONCLUSIONS

A wide range of problems for the management of comorbid disorders were identified. While solution of some problems will require resource allocation, many may be addressed by closer liaison between existing services.

Designing work experiences for persons with serious mental disorders

Persons with serious mental disorders need to participate in productive activities, including mainstream, competitive employment, during the course of their treatment and recovery.

Treatment programmes for people with both severe mental illness and substance misuse

BACKGROUND

Substance misuse in the context of severe mental illness can have detrimental effects. A variety of treatments exist, but the drive has been to provide programmes integrating treatment of both substance misuse and severe mental illness. Such programmes require additional resources and may require radical redesign of service delivery systems.

OBJECTIVES

To evaluate the effectiveness of treatment programmes within psychiatric care for people with problems of both substance misuse and serious mental illness.

SEARCH STRATEGY

Biological Abstracts (1985-1998), CINAHL (1982-1998), The Cochrane Library (Issue 3, 1998), The Cochrane Schizophrenia Group's Register of trials (August 1998), EMBASE (1980-1998), MEDLINE (1966-1998), PsycLIT (1974-1998) and Sociofile (1974-1998) were comprehensively searched. Citations of all trials were searched and further studies sought from published trials and their authors.

SELECTION CRITERIA

All randomised trials of any programme of substance misuse treatment for people with serious mental illness and current problems of substance misuse.

DATA COLLECTION AND ANALYSIS

Citations and, where possible, abstracts were independently inspected by reviewers, papers ordered, re-inspected and quality assessed. Data were also independently extracted. For homogeneous dichotomous data the Peto odds ratio (OR), and 95% confidence intervals (CI) were calculated on an intention-to-treat basis.

MAIN RESULTS

Six relevant studies, four of which were small, were identified. In general, the quality of design and reporting was not high. Clinically important outcomes such as relapse of severe mental illness, violence to others, patient or carer satisfaction, social functioning and employment were not reported. There is no clear evidence supporting an advantage of any type of substance misuse programme for those with serious mental illness over the value of standard care. No one programme is clearly superior to another.

REVIEWER'S CONCLUSIONS

The problems posed by substance misuse in the context of severe mental illness will not go away. The current momentum for integrated programmes is not based on good evidence. Implementation of new specialist substance misuse services for those with serious mental illnesses should be within the context of simple, well designed controlled clinical trials.

The relationship of counseling and self-help participation to patient outcomes in DATOS

Using a sample of 927 cocaine patients enrolled in programs in three modalities included in the national Drug Abuse Treatment Outcome Studies (DATOS), this investigation examined the relationship of three dimensions of treatment process on after-treatment cocaine and heavy alcohol use and predatory illegal activity. Logistic regression revealed significant reductions in all three outcomes and strong effects of treatment duration and after-treatment self-help, conditional on the modality. Results did not support the hypothesized relationship between treatment outcomes and amounts of counseling and during-treatment self-help. Findings support the robustness of duration effects and after-treatment self-help and contribute to the measurement methodology for calibrating treatment intensity. The strong after-treatment self-help effect in the two residential and inpatient modalities suggests these programs can improve treatment outcomes by making referral to after-treatment self-help participation a standard practice and installing mechanisms to increase the likelihood of attendance at least twice weekly during the year after treatment.

Economic impacts of assertive community treatment: a review of the literature

BACKGROUND

Assertive community treatment (ACT) is an extensively studied and widely imitated community support treatment model for severely mentally ill individuals. Several previous reviews have documented its favourable effects on clients and their families. This is the first review to focus on economic outcomes.

METHODS

Nineteen randomized studies and 15 nonrandomized studies describing ACT programs were identified based on 2 criteria: 1) provision of services primarily in the community and 2) shared caseloads. Percentage reduction in hospital days was calculated for the 34 study sites where reported data allowed it. Multiple-regression methods were used to relate reduction in hospital days to program fidelity and other contextual factors. The impacts of ACT on emergency-room use, use of outpatient services, housing, costs, and other economic outcomes were also examined.

RESULTS

Higher-fidelity programs appear to reduce hospital days by about 23 percentage points more than lower-fidelity programs (95% CI = -41.2, -5.2). The estimated regression coefficients imply that a high-fidelity program reduces hospitalizations by about 58% over 1 year if the alternative involves some type of case management and by 78% if it does not. ACT appears to increase the proportion of clients who live in independent housing situations, but the effect on use of supervised housing, and therefore on housing costs, is ambiguous. The effects on use of most other resources are inconsistent across studies. Overall, ACT appears to result in somewhat lower costs, whatever the perspective of analysis adopted.

CONCLUSIONS

The most reliable cost offset to ACT treatment costs appears to be reduced hospital use. Using Quebec costs, an ACT program must enroll people with prior hospital use of about 50 days yearly, on average, to break even. As care systems evolve to reduce their reliance on hospitalization as a care modality with or without ACT, this threshold will become increasingly difficult to achieve. The primary justification for implementing ACT services will then become their clinical benefits.

State-of-the-art challenges for mental health services research

BACKGROUND: Research-based, state-of-the-art services for people with serious mental disorders would consist of demonstrably effective treatments, organized synergistically, and financed in ways that create incentives to provide such treatment. While research exists in these domains of treatment, organization and financing, this research base contains significant gaps, and what is known frequently neither informs policy making nor enters practice. REVIEW: The NIMH services-research portfolio has identified successful patient-level and system-level interventions for people with serious mental disorders, but much of this research has yet to make its way into practice. Similarly, while we have made progress in asking "what is good care?", we have much less information about the answers to "what constitutes an adequate try?". Writing a prescription for an efficacious medication does not constitute an adequate trial of that medication. Similarly, offering people boring psychosocial rehabilitation programs does not constitute an adequate try of promoting recovery via rehabilitation services, but what does? Defining what constitutes an adequate try can be a way of allocating scarce resources or it can be a polite way of defining when a system gets to give up on someone. As state governments move to contract with managed care entities for services for Medicaid beneficiaries, one of the great contracting challenges is defining and monitoring the provision of what constitutes an adequate try. DISCUSSION: To obtain better value for our health care expenditures, we need to find ways to get what we know works into practice, whether we are contracting for services or deciding which clinical therapies to pursue. For example, problem-oriented family therapy has been shown to improve clinical outcomes for people with schizophrenia, yet such interventions are rare in practice. We also need to pay more attention to the quality of the clinical care actually being delivered - not what was prescribed, nor what the clinician was trained in, nor what the job description was, but what actually is occurring. Figuring out how to contract for and disseminate efficacious treatments so that they occur and are effective in real-world settings is critically important yet is a largely unexplored area of services research. We need to answer both "what is good care?" and "how do we get it to happen?".
