Impact of program services on treatment outcomes of patients with comorbid mental and substance use disorders

REDD-PAC Cohort Description: Researching Dual Diagnosis - Prognosis and Characteristics

OBJECTIVE

Evidence from real-world integrated dual diagnosis treatment programs is limited. In 2017 we decided to establish the REDD-PAC cohort with the aim to provide more in-depth information regarding the effect of integrated treatment.

METHODS

The REDD-PAC cohort includes more than 2,500 patients with dual diagnosis that have been treated at an in-patient department specializing in the integrated treatment of both psychiatric illness and substance use disorder in Denmark in the period from 2002 to 2017. The collected data included information on diagnosis as well as patient-completed questionnaires regarding anxiety, depression, self-worth, and use of substances. Data regarding medications prescribed and administered, weight, height, and blood pressure were also included.

RESULTS

The primary diagnosis was psychosis spectrum disorder (37.0%), followed by affective disorders (18.8%). More than two-thirds of the patients were male, and most patients had a weak connection to the labor market and basic schooling. Patients were generally very motivated for treatment.

CONCLUSIONS

Further linking the data to Danish national register data makes it possible to follow individual trajectories pre- and post-admission as well as to access complete follow-up data regarding long-term outcomes, e.g., use of health services, mortality, morbidity, crime, and social circumstances. This article describes both the overarching aims of the REDD-PAC cohort and the basic diagnostic and sociodemographic characteristics of the cohort.

Applying Implementation Drivers to Scale-up Evidence-Based Practices in New York State

Mental health authorities in several states, often working with academic partners, have played important roles in disseminating evidence-based practices (EBPs) for adults diagnosed with serious mental illness. This work has been facilitated by intermediary organizations that work directly with providers to implement EBPs. This report uses two case studies to describe how the Center for Practice Innovations (CPI), an intermediary organization, has used the Active Implementation Research Network’s nine implementation drivers to successfully implement EBPs across the large state of New York. One case study focuses on supported employment and the second on integrated treatment for co-occurring mental health and substance use conditions. We provide these case studies to illustrate how intermediary organizations can use implementation science to organize and select effective support strategies to disseminate and implement a range of EBPs within a state system.

Review of organizational effects on the outcome of mental health treatments

OBJECTIVE

As there are theoretical, clinical, and "common sense" reasons to expect a relationship between organizational factors and outcome in clinics providing psychotherapy and other mental health treatments, a review of empirical research in this area was undertaken with the aim of finding empirical evidence for organizational effects.

METHODS

A structured search for studies on organizational differences in patient mental health outcomes was performed using EBSCO host, Cochrane Library Database, and the Health Systems Evidence database at McMasters University. Finished studies published in English were included if they presented data from more than one mental health service and used change in symptom, level of functioning, or quality of life as outcome.

RESULTS

The search yielded not more than 19 studies fulfilling inclusion criteria. All studies showed some evidence for organization effects, and there was some evidence for organizational climate and culture explaining differences in outcome.

CONCLUSION

Given that mental health treatments are likely to be especially susceptive to organizational effects, it is remarkable that not more research has been devoted to this. Clearly, more research is needed to study the consequences of work organization for the outcome of psychotherapy. Methodological issues in organizational studies are discussed.

Disparities in Latino substance use, service use, and treatment: implications for culturally and evidence-based interventions under health care reform

BACKGROUND

The goal of this systematic literature review was to enhance understanding of substance use, service use, and treatment among Latino subgroups to improve access to care and treatment outcomes in an era of health care reform.

METHODS

The authors used 13 electronic databases and manually searched the literature from January 1, 1978, to May 30, 2013. One hundred (69%) of 145 primary research articles met the inclusion criteria. Two blinded, independent reviewers scored each article. Consensus discussions and a content expert reconciled discrepancies.

RESULTS

Current rates of alcohol and substance abuse among Latinos are comparable to or surpass other U.S. ethnic groups. Disparities in access and quality of care are evident between Latinos and other ethnic groups. As a heterogeneous group, Latinos vary by geographic region in terms of substance of choice and their cultural identity takes precedence over general ethnic identity as a likely determinant of substance abuse behaviors. There is growing research interest in systems influencing treatment access and adherence among racial/ethnic and gender minority groups. However, studies on Latinos' service use and immediate treatment outcomes have been both limited in number and inconsistent in findings.

CONCLUSIONS

This review identified human capital, quality of care, and access to culturally responsive care as key strategies to eliminate disparities in health and treatment quality. Implications are discussed, including the need for effectiveness studies on Latinos served by systems of care that, under health care reform, are seeking to maximize resources, improve outcomes, and reduce variation in quality of care.

Comparing barriers to mental health treatment and substance use disorder treatment among individuals with comorbid major depression and substance use disorders

Barriers to both mental health and substance use disorder treatments have rarely been examined among individuals with comorbid mental health and substance use disorders. In a sample of 393 adults with 12-month major depressive episodes and substance use disorders, we compared perceived barriers to these two types of treatments. Data were drawn from the 2005-2011 U.S. National Surveys on Drug Use and Health. Overall, the same individuals experienced different barriers to mental health treatment versus substance use disorder treatment. Concerns about negative views of the community, effects on job, and inconvenience of services were more commonly reported as reasons for not receiving substance use disorder treatment. Not affording the cost of care was the most common barrier to both types of treatments, but more commonly reported as a barrier to mental health treatment. Improved financial access through the Affordable Care Act and parity legislation and integration of mental health and substance use disorder services may help to reduce treatment barriers among individuals with comorbid mental health and substance disorders.

Disparities in completion of substance abuse treatment between and within racial and ethnic groups

OBJECTIVE

To evaluate disparities in substance abuse treatment completion between and within racial and ethnic groups in publicly funded treatment in Los Angeles County, California.

DATA SOURCE

The Los Angeles County Participant Reporting System with multicross-sectional annual data (2006-2009) for adult participants (n = 16,637) who received treatment from publicly funded programs (n = 276) for the first time.

STUDY DESIGN

Retrospective analyses of county discharge and admission data. Hierarchical linear regressions models were used to test the hypotheses.

DATA COLLECTION

Client data were collected during personal interviews at admission and discharge for most participants.

PRINCIPAL FINDINGS

African Americans and Latinos reported lower odds of completing treatment compared with Whites. Within-group analysis revealed significant heterogeneity within racial and ethnic groups, highlighting primary drug problem, days of drug use before admission, and homelessness as significant factors affecting treatment completion. Service factors, such as referral by the criminal justice system, enabled completion among Latinos and Whites only.

CONCLUSIONS

These findings have implications for reducing health disparities among members of racial and ethnic minorities by identifying individual and service factors associated with treatment adherence, particularly for first-time clients.

Impact of Abstinence Self-Efficacy and Treatment Services on Physical Health-Related Behaviors and Problems among Dually Diagnosed Patients

OBJECTIVE: Physical health problems are pervasive among patients with co-occurring substance use and mental disorders. Yet, drug treatment programs often ignore tobacco use and its association with health. Abstinence self-efficacy has been associated with improved outcomes for co-occurring disorders, which in turn may also impact physical health. This study had the goal of assessing whether abstinence self-efficacy for drugs and alcohol, and provision and use of services would influence tobacco use and other health-related outcomes among 351 individuals with co-occurring disorders in residential drug treatment. METHODS: Structural models tested the impact of baseline abstinence self-efficacy and treatment service characteristics on 6-month outcomes of health problems, functional limitations, health perceptions, and cigarette and heavy alcohol use. Demographics and baseline values for outcome variables were included as covariates. RESULTS: Correlations within time for poor health, cigarette use, and heavy alcohol use were substantial. A longer time in drug treatment was associated with less cigarette and heavy alcohol use at a 6-month follow-up. Baseline health problems were associated with more cigarette use and functional limitations at 6-months. Abstinence self-efficacy did not predict less cigarette use, but predicted less heavy alcohol use and fewer functional limitations. Availability of specialized dual-diagnosis groups and more on-site psychological services were not directly associated with outcomes, but had an impact through indirect effects on more psychological service utilization which predicted better subjective health. CONCLUSIONS: Improving overall treatment retention and services utilization among patients with co-occurring disorders may generalize to improved health perceptions, but specific health promotion and smoking-cessation interventions are warranted to improve health outcomes.

Training addiction counselors to implement CBT for depression

Many clients in publicly funded substance abuse treatment programs suffer from depression yet lack access to effective mental health treatment. This study sought to examine whether addiction counselors could be effectively trained to deliver group CBT for depression and to ascertain client perceptions of the treatment. Five counselors were trained in the therapy and treated 113 clients with depression symptoms. Counselors demonstrated high fidelity to the therapy and client perceptions of the therapy were positive. Our results suggest that training addiction counselors to deliver group CBT for depression is a promising integrated treatment approach for co-occurring depression and substance disorders.

Integrating care for people with co-occurring alcohol and other drug, medical, and mental health conditions

Most people with alcohol and other drug (AOD) use disorders suffer from co-occurring disorders (CODs), including mental health and medical problems, which complicate treatment and may contribute to poorer outcomes. However, care for the patients' AOD, mental health, and medical problems primarily is provided in separate treatment systems, and integrated care addressing all of a patient's CODs in a coordinated fashion is the exception in most settings. A variety of barriers impede further integration of care for patients with CODs. These include differences in education and training of providers in the different fields, organizational factors, existing financing mechanisms, and the stigma still often associated with AOD use disorders and CODs. However, many programs are recognizing the disadvantages of separate treatment systems and are attempting to increase integrative approaches. Although few studies have been done in this field, findings suggest that patients receiving integrated treatment may have improved outcomes. However, the optimal degree of integration to ensure that patients with all types and degrees of severity of CODs receive appropriate care still remains to be determined, and barriers to the implementation of integrative models, such as one proposed by the Institute of Medicine, remain.

Age and HIV sexual risk among women in methadone treatment

This study examines the relationship between age and HIV sexual risk behaviors among a random sample of 372 women in methadone treatment in New York City. Logistic regression results indicate that women of all ages are at risk for HIV through inconsistent condom use. Exposure to intimate partner violence (IPV), alcohol use, and HIV-negative status are associated with inconsistent condom use during vaginal sex. Age (35-44), having a main sexual partner with an HIV risk factor, IPV, and alcohol use are associated with using crack or cocaine during sex. Similarly, age (35-44), having a main sexual partner with an HIV risk factor, IPV, and drug use are associated with consuming four or more drinks prior to sex. The findings highlight the importance of age-appropriate HIV prevention and intervention strategies, as well as the need to address intimate partner violence, mental health, polysubstance use, and relational factors associated with HIV sexual risk behaviors among women in methadone treatment.

Stability of Outcomes Following Residential Drug Treatment For Patients with Co-occurring Disorders

OBJECTIVE: Few studies have examined the stability of both substance use and mental health outcomes following residential drug abuse treatment for individuals with co-occurring disorders (COD). This study examines outcomes at 6 and 12 months for individuals with COD, in relationship to services received over the follow-up period. METHODS: Participants with COD (N=310) were sampled from 11 residential drug abuse treatment programs and completed in-depth assessments within 30 days of intake and at 6- and 12-month follow-ups. A path model was developed testing the relationships among treatment participation and services received, psychological status, and substance use outcomes across the two follow-up points. RESULTS: Retention for at least 90 days in residential drug treatment was associated with less inpatient mental health treatment and more mental health services received at 6 months; outpatient mental health treatment was associated with reduced substance use at 6 months. Substance use at 6 months was associated with more psychological distress at both 6 and 12 months and more inpatient mental health treatment at 12 months. CONCLUSIONS: Findings suggest that receipt of mental health services following residential drug abuse treatment for patients with COD is critical to improving their longer-term outcomes.

Treatment of cannabis use disorders in people with schizophrenia spectrum disorders - a systematic review

BACKGROUND

Cannabis use disorders (CUD) are prevalent among people with schizophrenia spectrum disorders (SSD), with a range of detrimental effects, e.g. reduced compliance to medication and psychosocial interventions, and increased level of psychotic-dimension symptoms. The aim of this study was to review literature on treatments of CUD in SSD-patients.

METHODS

PubMed, PsycINFO, EMBASE, and The Cochrane Central Register of Controlled Trials were searched.

RESULTS

41 articles were selected, 11 treating cannabis as a separate outcome. Contingency management was only effective while active. Pharmacological interventions appeared effective, but lacked randomized controlled trials (RCTs). Psychosocial interventions, e.g. motivational interviewing and cognitive behavior therapy (CBT), were ineffective in most studies with cannabis as a separate outcome, but effective in studies that grouped cannabis together with other substance use disorders.

CONCLUSIONS

Insufficient evidence exists on treating this form of dual-diagnosis patients. Studies grouping several types of substances as a single outcome may overlook differential effects. Future RCTs should investigate combinations of psychosocial, pharmacological, and contingency management.

Influence of ownership on access in outpatient substance abuse treatment

Marked changes in ownership and control in substance abuse treatment delivery have garnered the attention of providers and policymakers alike. The proliferation of private for-profit providers and the shift to a delivery system that may be more explicitly influenced by financial incentives are of particular concern for this vulnerable population. This work empirically addresses how treatment unit ownership affected access and retention between 1995 and 2005 in the United States. Regressions show statistically significant associations between unit ownership and both restricted treatment access and shortening of treatment duration for financial reasons. In comparison to private nonprofit and public units, private for-profit units were less likely to provide initial treatment access and reported shortened treatment for a greater percentage of clients unable to pay. Other organization characteristics, such as methadone-maintenance programs and managed care participation, also were associated with limiting treatment accessibility. While this work does not determine the underlying motivation behind access limitations, continued shifts in ownership structure should heighten the attention of policymakers.

Community perceptions of mental health needs in an underserved minority neighborhood

Accurate information is needed to facilitate health equity in underserved communities. This community-based participatory study asked residents about the meaning of mental health, their perceptions of community mental health needs, barriers to accessing mental health care, and acceptability of mental health services that are integrated in primary health clinics. Forty-five primarily African-American residents from urban communities participated in focus groups. Findings revealed high prevalence of substance abuse, depression, crime, and stigma about mental illness, with multiple access barriers. Participants were receptive to mental health care integrated in primary care, if others did not know they were receiving mental health care.

Disparities in use of mental health and substance abuse services by persons with co-occurring disorders

OBJECTIVES

Individuals with co-occurring mental and substance use disorders require psychiatric and substance abuse treatments. A critical question is whether these individuals are treated for both disorders.

METHODS

This study prospectively examined 24-month service utilization patterns of 224 persons with co-occurring disorders who were recruited from crisis residential programs in the mental health treatment system (N=106) and from crisis residential detoxification programs in the substance abuse treatment system (N=118) in San Francisco. Utilization data were collected from the billing-information systems of both treatment systems. Demographic and clinical data were obtained in interviews with participants. Data were analyzed for group differences with chi square tests and logistic, linear, and zero-truncated negative binomial regression.

RESULTS

After the analyses controlled for demographic and clinical factors, participants recruited from the substance abuse treatment system were less likely than those from the mental health treatment system to obtain any mental health services, mental health day treatment, transitional residential care, case management, and other outpatient services (p<.001 for all comparisons). They were more likely to obtain crisis residential detoxification (p=.003), had more days of drug residential treatment (p=.028), but received fewer hours of outpatient services (p=.012).

CONCLUSIONS

There were disparities in patterns of service utilization, although there were no significant diagnostic differences between the two groups. These findings should be valuable in considering systems development and modification. Furthermore, they can contribute to research about factors that underlie results. Study replications should be conducted to assess the robustness of these findings in other locales.

Client retention in residential drug treatment for Latinos

Client drop out from treatment is of great concern to the substance abuse field. Completion rates across modalities vary from low to moderate, not ideal since length of stay has been positively and consistently associated with better client outcomes. The study explored whether client characteristics shown to be related to retention were associated with treatment completion and treatment duration for a sample of 164 Latino substance users who entered a culturally focused residential program. In-person client interviews were conducted within a week of program admission. Logistic regression analysis was used to examine research questions. Clients most likely to drop out had self-reported co-occurring psychiatric diagnoses; they were 81% less likely to complete the program, suggesting that clients with mental health problems have a more difficult time remaining in residential treatment. Clients using drugs in the three months prior to entry were three and a half times more likely to be in the shorter stay group, and clients who lived in institutions prior to program entry were three times more likely to be in the longer-stay group. Factors contributing to drop out for this Latino sample were similar to those identified in the literature for non-Latino samples. Methods for addressing the needs of clients with co-occurring disorders are discussed.
