Substance use outcomes among individuals with severe mental illnesses receiving assertive community treatment: A systematic review

Assessing Tobacco Treatment Engagement in Assertive Community Treatment Programs

OBJECTIVE

Despite high tobacco use prevalence among those with serious mental illnesses, few Assertive Community Treatment (ACT) programs provide tobacco treatment. Understanding the factors associated with the intentions to engage in tobacco treatment from both provider and consumer perspectives is important. The purpose was to examine ACT providers' intention to provide and consumer intention to engage in tobacco treatment.

METHOD

A cross-sectional survey of ACT program providers (N = 51) and consumers (N = 43) from four community mental health centers. Multiple linear regression analyses were used to examine factors associated with the intentions to provide or engage in tobacco treatment from among attitudinal, subjective norms, and perceived behavioral control variables.

RESULTS

Providers reported positive attitudes, high degree of perceived behavior control, and high intentions for delivering tobacco treatment, but poor perceptions of subjective norms. These results were like consumers' intentions to engage in tobacco treatment. In regression analysis, only subjective norms and perceived behavior control were significant predictors for providers' intentions to provide tobacco treatment, but there were no significant predictors of consumers' intentions to engage in tobacco treatment. Both providers and consumers endorsed poor implementation of evidence-based tobacco treatment.

CONCLUSION

Poor engagement in tobacco treatment within ACT programs indicates the need for policymakers to support tobacco treatment within the services. This finding calls for training of mental and behavioral health providers while supporting tobacco-free initiatives in ACT treatment service settings.

Remission with or without comorbid substance use disorders in early psychosis: long-term outcome in integrated care (ACCESS III study)

Introduction

Schizophrenia-Spectrum-Disorders are associated with poor long-term outcome as well as disability and often severely affect the lives of patients and their families often from symptom onset. Up to 70% of first episode psychosis (FEP) patients suffer from comorbid substance use disorders (SUD). We aimed at studying the course of illness in FEP patients within evidence-based care, with and without comorbid SUD, to examine how decreased, remitted or persistent substance use impacted rates of a combined symptomatic and functional long-term recovery compared with patients without SUD.

Methods

ACCESS III is an integrated care model for FEP or patients in the early phase of non-affective and affective psychotic disorders. Treatment trajectories of patients, who had been in ACCESS care for 1 year, with and without SUD were compared with regard to the course of illness and quality of life using Mixed Model Repeated Measures (MMRM) and recovery rates were compared using binary logistic regression. Change in substance use was coded as either persistent, decreased/remitted or no use.

Results

ACCESS III was a prospective 1-year study (N = 120) in patients aged 12-29 years. Of these, 74 (61.6%) had a comorbid SUD at admission. There were no group differences regarding the course of illness between patients with or without comorbid SUD or between patients with a substance abuse or substance dependence. The only outcome parameter that was affected by SUD was quality of life, with larger improvement found in the group without substance use (p = 0.05) compared to persistent and remitted users. Using LOCF, 44 patients (48.9%) fulfilled recovery criteria at the endpoint; recovery did not differ based on substance use status.

Discussion

SUD and especially substance dependence are common in psychotic disorders even in FEP patients. Evidence-based integrated care led to long-term improvement in patients with comorbid SUD and rate of recovery did not differ for patients with substance use.
