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

Integrated behavioral treatments for comorbid anxiety and substance use disorders: A model for understanding integrated treatment approaches and meta-analysis to evaluate their efficacy

INTRODUCTION

Substance use disorders (SUD) and anxiety disorders are highly comorbid, and this comorbidity is associated with poor clinical outcomes. Emerging research in the last decade has shifted from addressing these problems separately to the development and evaluation of behavioral treatments that integrate care for anxiety disorders (or elevated symptoms of anxiety) and SUD.

METHODS

An extensive literature search revealed a sufficient number of studies (K=11) to conduct a meta-analysis comparing the efficacy of integrated SUD/anxiety disorder behavioral treatment to SUD treatment alone on substance use and anxiety symptom outcomes. Randomized clinical trials including those with SUD and either anxiety disorders or elevations in constructs implicated in the maintenance of anxiety disorder/SUD comorbidity were included. This study meta-analyzes the effects of these studies.

RESULTS

Integrated treatments outperformed SUD treatments alone on both substance use and anxiety outcomes, with small to moderate effects favoring integrated treatments. There was no significant heterogeneity across studies in the primary analyses, such that moderator analyses to identify variables that yielded differential patterns of effect sizes were not conducted.

DISCUSSION

Integrated treatments for SUD/anxiety disorders demonstrate an incremental but significant and clinically meaningful improvement over SUD treatment alone for SUD/anxiety disorder comorbidity. Implications for future research and clinical practice paradigm shifting are discussed.

Profiles of individuals with cannabis-related disorders

Background: Profiles of individuals with cannabis-related disorders (CRD) in specialized addiction treatment centers serving high-need patients have not been identified. This longitudinal study developed a typology for 9,836 individuals with CRD attending Quebec (Canada) addiction treatment centers in 2012-2013. Methods: Data on sociodemographic, clinical and service use variables were extracted from several databases for the years 1996-1997 to 2014-2015. Individual profiles were produced using Latent Class Analysis and compared predicting health outcomes on emergency department (ED) use, hospitalizations and suicidal behaviors for 2015-2016. Results: Six profiles were identified: 1-Older individuals, many living in couples and working, with moderate health problems, receiving intensive general practitioner (GP) care and high continuity of physician care; 2-Older individuals with chronic CRD, multiple social and health problems, and low health service use (chronic CRD referred to experiencing CRD for several years; social problems related to homelessness, unemployment, having criminal records or living alone); 3-Students with few social and health problems, and low health service use; 4-Young adults, many working, with few health problems, least health service use and continuity of physician care; 5-Youth, many working but some criminal offenders, with 1 or 2 years of CRD, few health problems and high addiction treatment center use; and 6-Older individuals with chronic CRD and multiple social and health problems, high health service use and continuity of physician care. Profiles 6 and 2 had the worst health outcomes. Conclusions: For Profiles 2 to 5, outreach and motivational services should be prioritized, integrated health and criminal justice services for profile 5 and, for Profiles 2 and 6, assertive community treatments. Screening, brief intervention and referrals to addiction treatment centers may also be encouraged for individuals with CRD, particularly those in Profile 2. This cohort had high social and health needs relative to services received, suggesting continued need for care.

Development and Initial Pilot Testing of a fully integrated treatment for comorbid social anxiety disorder and alcohol use disorder in a community-based SUD clinic setting

OBJECTIVES

Social anxiety disorder (SAD) and alcohol use disorder (AUD) are highly comorbid and this comorbidity is associated with poorer clinical outcomes. Integrating exposure-based treatment for SAD into the context of typical AUD treatment programs should improve engagement and treatment outcomes for this population.

METHODS

After initial development of a fully integrated, intensive outpatient program (IOP) for individuals with comorbid SAD and AUD, patients with SAD and AUD were recruited from a community-based SUD specialty clinic (N = 56) and randomized to either (a) usual care (UC), consisting of the evidence-based Matrix Model of Addiction IOP; or (b) the Fully Integrated Treatment (FIT) for comorbid SAD and AUD IOP. Participants were assessed on indices of social anxiety and alcohol use.

RESULTS

By the 6-month follow-up, those in FIT showed superior improvement to UC on number of drinking days in the past 30 days and social anxiety severity at follow-up, but there were no differences between groups on quantity of alcohol consumed on drinking days. Alcohol-related problems improved in both groups, with no statistically significant differences. Within-group improvement was observed in FIT (but not in UC) on drinking to cope with social anxiety and avoidance of social situations without alcohol, but between-group effects were non-significant. In sum, the integrated treatment of SAD and AUD led to greater reductions in both the frequency of drinking and in social anxiety symptoms than usual care.

CONCLUSIONS

Targeting social anxiety in the context of AUD treatment is a promising approach to improving the treatment of this common comorbidity.

Economic and Social Factors That Predict Readmission for Mental Health and Drug Abuse Patients

According to the United Nations, curtailing the rise of mental illness and drug abuse has been an important goal for sustainable development of member states. In the United States, reducing readmission rates for mental health and drug abuse patients is critical, given the rising health care costs and a strained health care system. This study aims to examine economic and social factors that predict readmission likelihood for mental health and drug abuse patients in the state of New York. Patient admission data of 25,846 mental health patients and 32,702 drug abuse patients with multiple visits in New York hospitals in 2015 were examined. Findings show that economic factors like income level and payment type impact readmission rates differently: The poorest patients were less likely to get readmitted while patients with higher incomes were likely to experience drug relapse. Regarding social factors, mental health patients who lived in neighborhoods with high social capital were less likely to be readmitted, but drug abuse patients in similar areas were more likely to be readmitted. The findings show that policy-makers and hospital administrators need to approach readmission rates differently for each group of patients.

Addressing treatment capacity of uninsured adults with co-occurring disorders

Purpose

The purpose of this paper is to report on the success of an initiative involving the transformation of a group of small substance use treatment only or mental health treatment only provider agencies serving uninsured adults into providers of co-occurring disorder treatment.

Design/methodology/approach

The paper uses a case study narrative to describe the initiative and the transformation of the participant agencies from being providers of mental health or substance use treatment to providers of co-occurring disorders.

Findings

Six agencies serving uninsured adults expanded their scope of patient treatment services to include the capacity to treat adults with co-occurring disorders. This was achieved with modest support funding from a local foundation. The initiative has been ongoing for five years.

Practical implications

The outcome of this initiative demonstrates the financial and practical feasibility of improving and expanding treatment services to low-resourced patient populations. The participating agencies were able to improve their capacity to treat patients with substance use or mental health issues that previously they were not prepared to treat and thus increased their ability to provide integrated care.

Originality/value

The initiative described here shows that the treatment of concomitant substance use and mental health disorders is within the range of many small-scale treatment providers, if provided the leadership and support. Delivery of effective treatments to populations experiencing co-occurring disorders that are underserved and undertreated are achievable in community-based clinical practices. This has implications for developing treatment capacity outside of hospital settings to enable treatment of co-occurring disorders to become more accessible.

Mental Health Services and Personal Recovery in California: A Population-Based Analysis

OBJECTIVE

Personal recovery measures have been examined among treatment-seeking individuals enrolled in high-quality care. The authors examined whether utilization of mental health services as typically delivered is associated with personal recovery among adults with clinically significant psychological distress.

METHODS

The Kessler Psychological Distress Scale (K-6) measured respondents' (N=1,954) psychological distress level. The authors also assessed five dimensions of personal recovery-hope, life satisfaction, empowerment, connectedness, and internalized stigma. Multivariable linear regression analyses were used to examine relationships between personal recovery and treatment, self-reported treatment completion, provider type, and adequacy of care, adjusting for covariates including K-6 score.

RESULTS

Participants who received care >12 months prior to the survey reported lower levels of hope (95% confidence interval [CI]=-0.36, -0.06, p<0.01), empowerment (95% CI=-0.26, -0.02, p<0.05), and connectedness (95% CI=-0.37, -0.06, p<0.01) than those who had not received treatment. Those who received care in the past 12 months reported lower levels of hope (95% CI=-0.47, -0.14, p<0.001) and life satisfaction (95% CI=-0.42, -0.05, p<0.01). However, treatment completion was associated with higher levels of empowerment (95% CI=0.02, 0.56, p<0.05) and hope (95% CI=0.04, 0.62, p<0.05) and lower levels of stigma (95% CI=-1.21, -0.21, p<0.01) compared with noncompletion. Differences according to provider type and adequacy of care were nonsignificant.

CONCLUSIONS

Utilization of mental health services was associated with lower levels of personal recovery, which may indicate that care-as typically utilized and received-does not promote personal recovery. Longitudinal research is needed to determine causal relationships underlying these associations.

Evaluation of an integrated group cognitive-behavioral treatment for comorbid mood, anxiety, and substance use disorders: A pilot study

This paper presents the development and preliminary evaluation of an integrated group cognitive-behavioral treatment (CBT) for comorbid mood, anxiety, and substance use disorders. The 12-session, manualized treatment was developed collaboratively by a mental health program in a teaching hospital and a community-based addictions service and administered in both settings. Results from an uncontrolled effectiveness trial of 29 treatment completers suggest that integrated group CBT may reduce stress and alcohol use symptoms and improve substance refusal self-efficacy. Changes in symptoms of anxiety, depression, and drug use were not significant, although the effect size for anxiety reduction was in the medium range. Nonetheless, the clinical significance of treatment effects on mood, anxiety, and substance use symptoms was modest. Changes in coping skills and quality of life were not significant, although medium-to-large effects were observed for changes in several coping skills. Participants reported being highly satisfied with treatment, found the treatment strategies to be useful, and noted an improvement in their functioning, particularly socially. Methodological and sample size limitations warrant more rigorous follow-up investigations of this treatment. Results are considered in the context of the current literature on integrated psychological treatments for these common comorbidities.

Racial/Ethnic Differences in Contemporaneous Use of Mental Health and Substance Use Treatment Among Individuals Experiencing Both Mental Illness and Substance Use Disorders

This study examined whether the well-established racial/ethnic differences in mental health service utilization among individuals with mental illness are reflected in the treatment utilization patterns of individuals experiencing both mental illness and substance use disorders, particularly in regards to the use of contemporaneous mental health and substance abuse treatment. Using pooled data from the National Survey on Drug Use and Health (2009-2013), the patterns of mental health and substance use treatment utilization of 8748 White, Black, or Latino individuals experiencing both mental illness and substance use disorders were analyzed. Multinomial logistic regression was conducted to test the relationships among racial/ethnic groups and the receipt of contemporaneous treatment, mental health treatment alone, and substance use treatment alone as compared with no treatment utilization. Results indicated that Black and Latino respondents were less likely to receive contemporaneous treatment than Whites respondents. Also, significantly associated with outcomes were several interactions between race/ethnicity and predisposing, need and enabling factors known to be associated with service utilization. The findings suggest that an underlying mechanism of racial/ethnic differences among individuals with co-occurring mental illness and substance use disorders in the treatment utilization may differ by the specific types of treatment and between Blacks and Latinos. Therefore, efforts to reduce these disparities should consider specialty in each treatment settings and heterogeneity within diverse racial/ethnic groups.

Factors associated with high use of general practitioner and psychiatrist services among patients attending an addiction rehabilitation center

BACKGROUND

This study aimed to 1) identify the characteristics of individuals with substance use disorders (SUDs) who make high use of services provided by general practitioners (GP) and psychiatrists while receiving services concurrently from an addiction rehabilitation center (ARC), and 2) to compare high service users to moderate and low service users.

METHODS

Data were compiled for 4,407 individuals with SUDs who were receiving services from an ARC in 2004. The data came from the merging of four databases: the ARC data registry (January 1(st), 2004-December 31, 2004), the Quebec Health Insurance Board database (March 31, 2003-April 1st, 2005), the Quebec provincial database for hospitalizations (March 31, 2003-April 1st, 2005), and the Quebec National Institute of Public Health database (2004). Independent variables were grouped according to the Andersen Behavioral Model of Health Services Use: predisposing, enabling and need factors. Generalized estimating equations analyses were performed to assess the influence of individual and neighborhood-level characteristics on high use of services outside the ARC provided by GPs and psychiatrists. Benjamini-Hochberg's procedure was applied to correct for multiple comparisons.

RESULTS

About 97 % of individuals attending the ARC consulted a GP or a psychiatrist during the two-year study period, for a mean of 1.5 consultations per month. Findings revealed that 5 % of the sample made 26 % of all consultations over the two years, and they were defined as high users. No single predisposing factor was associated with high use. One enabling factor significantly increased the risk of being a high user of services from general practitioners and psychiatrists: receiving services at the ARC for three years prior to 2004. Four needs factors, all related to mental health diagnoses (schizophrenia, mood disorder, anxiety disorder, personality disorder), predicted high use of general practitioner and psychiatrist services.

CONCLUSIONS

This study found that nearly all individuals with SUDs receiving services from an ARC were users of health services from GPs and psychiatrists outside the ARC. High users most probably accessed them in inpatient settings. No previous study has compared high service users with low and moderate users among individuals with SUDs. Considering that ARCs are treating individuals with complex needs, some of whom make high use of medical professionals, both ARCs and their clients could benefit from increased collaboration and integration between the addictions and mental healthcare sectors.

Exercise training - A beneficial intervention in the treatment of alcohol use disorders?

BACKGROUND

A growing body of evidence suggests that exercise training may have multiple beneficial effects in individuals with mental health or substance use disorders. Yet, relatively little knowledge exists regarding the benefits of exercise training to augment treatment for alcohol use disorders (AUDs).

PURPOSE

The purpose of this narrative review is to present a summary of the growing body of published literature supporting exercise training as a treatment strategy for individuals with AUDs. We will provide evidence on the myriad of ways in which exercise may exert a positive effect on AUD outcomes including stress, anxiety, impulsivity, and depression. Further, we will explore how these mechanisms share common neurobiological pathways. The role of exercise in enhancing the social environment and increasing individual self-efficacy to reduce excess and/or inappropriate alcohol consumption will also be discussed.

DISCUSSION

We will conclude with a description of completed investigations involving exercise training and provide suggestions for next steps in this innovative field of study.

The impact of alcohol use severity on anxiety treatment outcomes in a large effectiveness trial in primary care

OBJECTIVE

The presence of anxiety disorders is associated with poorer alcohol use disorder treatment outcomes, but little is known about the impact of alcohol use problems on anxiety disorder treatment outcomes despite their high comorbidity. The current study examined the impact of alcohol use symptom severity on anxiety disorder treatment outcomes in a multi-site primary care effectiveness study of anxiety disorder treatment.

METHOD

Data came from the Coordinated Anxiety Learning and Management (CALM) effectiveness trial. Participants (N=1004) were randomized to an evidence-based anxiety intervention (including cognitive behavioral therapy and medications) or usual care in primary care. Participants completed measures of alcohol use, anxiety, and depression at baseline, 6-, 12-, and 18-month follow-up periods. Patients with alcohol dependence were excluded.

RESULTS

There were no significant moderating (Treatment Group × Alcohol Use Severity) interactions. The majority of analyses revealed no predictive effects of alcohol use severity on outcome; however, alcohol problems at baseline were associated with somewhat higher anxiety and depression symptoms at the 18-month follow-up.

CONCLUSIONS

These data indicate that patients with alcohol problems in primary care can be effectively treated for anxiety disorders. Baseline alcohol problems were associated with some poorer long-term outcomes, but this was evident across CALM and usual care. These findings provide preliminary evidence that there may be no need to postpone treatment of anxiety disorders until alcohol problems are addressed, at least among those who have mild to moderate alcohol problems. Replication with more severe alcohol use disorders is needed.

“My actual mind and body is in a better place, I just feel better since coming here”: recovery and mental wellbeing

Purpose

– An increasing literature points to the efficacy and importance of mutual aid groups for people recovering from substance dependency. However, there is a paucity of qualitative evidence into the experiences and perceptions of service users attending UK-based mutual aid groups, and the implications they could have for recovery and mental wellbeing. The paper aims to discuss this issue.

Design/methodology/approach

– A phenomenological approach was chosen to explore the experiences and perceptions of service users and mentors at a mutual aid group in Leeds. Semi-structured interviews were conducted with service users and mentors (ex-service users) involved with the project. Thematic analysis was used to analyse the data.

Findings

– This paper focuses on the influence of mutual aid attendance on mental wellbeing. It was found that attendance seemed to have positive influences on providing structure, reducing stress and boredom, “broadening the mind” and providing service users with a social network that supported their recovery and mental wellbeing. However, it was also found that for those that have little outside the project, dependency on the group could develop, resulting in negative consequences on mental wellbeing.

Originality/value

– This paper provides an increased understanding of why mutual attendance has influences on mental wellbeing, as well as the implications such impacts have on recovery trajectories.

Trends in hospital discharges and dispositions for episodes of co-occurring severe mental illness and substance use disorders

This study examined trends in general hospital discharges and dispositions involving episodes of severe mental illness (SMI) with and without co-occurring substance use disorders. We analyzed data from the National Hospital Discharge Survey from 1979 through 2008. Discharges involving SMI and co-occurring substance use disorders (COD) were associated with shorter lengths of stay and had a greater likelihood of being discharged routinely or home and reduced likelihood of being transferred to a short- or long-term facility. Although COD discharges had a greater odds of leaving against medical advice than SMI discharges, this effect was not significant over time. A greater understanding of hospital discharge planning practices is needed to ensure that patients are linked to appropriate aftercare services.

Detoxification History and 2-Year Outcomes of Substance Use Disorder Treatment and Mutual-Help Group Participation

Little is known about detoxification (detox) history as a risk factor for poor treatment outcomes among dually diagnosed (substance use and other mental health disorders) patients. We compared patients with a detox history with those who had never received detox on baseline characteristics, subsequent treatment and mutual-help group participation, and substance use and related outcomes at 6-month, 1-year, and 2-year follow-ups. Having a detox history was associated with poorer status at treatment intake, but detoxed patients were functioning as well as never-detoxed patients on alcohol and drug use severity 2 years later. However, having a detox history at baseline was associated with poorer psychological and legal functioning at follow-ups. Assessing detox history in mental health programs would be feasible to implement routinely. Targeting more comprehensive mental health, case management, and 12-step facilitation services to dually diagnosed patients with a history of detox may improve mental health and criminal involvement status.
