Hospitalisation of severely mentally ill patients with and without problematic substance use before and during Assertive Community Treatment: an observational cohort study

Substance Use Disorders as a Critical Element for Decision-Making in Forensic Assertive Community Treatment: A Systematic Review

Introduction: The prevalence of substance use disorders in forensic populations is high. They are an important factor linked to negative outcomes in mentally ill offenders and are detrimental to forensic or non-forensic outcome measures. In contrast, substance use disorders are often underdiagnosed and undertreated, especially in forensic settings. Forensic Assertive Community Treatment is a forensic adaptation of regular assertive community treatment, combined with essential elements of forensic rehabilitation theories. Little is known however on the effectivity of forensic assertive community treatment when it comes to substance use disorders or what their exact role is on the outcome measures. In this paper, we explore how SUD is treated in Forensic assertive community treatment and how it relates to the forensic and non-forensic outcome measures. Methods: We performed a systematic review (PRISMA) of forensic Assertive community treatment teams that followed the main evidence-based principles of regular assertive community treatment and added basic elements of forensic rehabilitation. We analyzed articles the Psychinfo and Medline databases dating from 2005 to 2020. Fifteen studies fit the search criteria and were included in the analysis. The Quality of the studies was assessed using the Newcastle-Ottawa scale. Results: SUD was highly prevalent in all studies. Patients entered FACT through two pathways, either from a care continuum or directly from prison. The severity of SUD at intake emerges as a critical element when deciding which pathway to choose, as a high severity-score at the start of FACT follow-up was linked to recidivism. While differing in method all studies offered integrated SUD treatment. These included evidence-based techniques like CBT, therapeutic communities, and Substance Abuse Management Module. Though results on SUD outcomes were mixed 4 studies mentioned abstinence in 50-75%. The severity of SUD tended to increase initially and to stabilize afterwards. Conclusion: Severity of SUD at intake emerges as a decisive element in decision-making on entering FACT teams directly from prison or through a care-continuum. The ways to provide SUD treatment varied and outcomes for SUD were mixed. SUD was found to be detrimental to forensic and non-forensic outcome measures, such as recidivism or hospitalizations during FACT treatment.

Substance use among patients in specialized mental health services in Norway: prevalence and patient characteristics based on a national census

PURPOSE

The aim of this study was to investigate the clinical and demographic variation in the prevalence of substance use among the general psychiatric population in Norway.

METHODS

A national census in psychiatric institutions and outpatient clinics was conducted. Data were returned for 2358 inpatients (response rate, 65%) and 23,167 outpatients (response rate, 60%). Substance use was measured based on substance use disorder diagnosis or reported substance use in the last 4 weeks (alcohol 2-4 days a week or more frequently/illicit drug use). Regression analyses controlling for demographic and sociodemographic characteristics were carried out.

RESULTS

Substance use was identified in 32.4% of inpatients and 13.9% of outpatients. The most frequently reported substances used were alcohol, sedatives and cannabis. Among inpatients, the prevalence of substance use was highest in patients with schizophrenia, personality disorders and anxiety disorders. Among outpatients, the prevalence was highest in patients with schizophrenia and other psychoses. Inpatients with anxiety disorders and outpatients with schizophrenia and other psychoses had a significantly higher risk of substance use than other patients. In both samples, the prevalence of substance use was higher among males, 24 to 29-year-olds and the most socially deprived.

CONCLUSIONS

This study provides further knowledge about patients at risk for co-morbid substance abuse and poor treatment outcomes. Clinicians may consider targeting patients with schizophrenia and other psychoses, young males and those who are socially deprived in efforts to prevent emerging substance abuse and improve outcomes.

MyCare study: protocol for a controlled trial evaluating the effect of a community-based intervention on psychosocial, clinical outcomes and hospital admission rates for adults with severe mental illness

INTRODUCTION

People with serious mental illness (SMI) often fail to receive adequate treatment. To provide a higher level of support, mental health systems have been reformed substantially to integrate mental healthcare into the community. MyCare is one such community-based mental health model of care. This paper describes the study protocol of a controlled trial examining the effect of MyCare on psychosocial and clinical outcomes and hospital admission and duration rates for adults with SMI.

METHODS AND ANALYSIS

This is a multisite non-randomised controlled trial with a 3, 6 and 12-month follow-up period. The study participants will be adults (18-64 years of age) with SMI recruited from Hobart, Launceston and the North-West of Tasmania. The treatment group will include adults who receive both the MyCare intervention and standard mental health support; the control group will include adults who receive only standard mental health support. The primary outcome includes psychosocial and clinical functioning and the secondary outcome will examine hospital admission rates and duration of stay. Mixed-effects models will be used to examine outcome improvements between intake and follow-up. This trial will generate the evidence needed to evaluate the effect of a community mental health support programme delivered in Tasmania, Australia. If MyCare results in sustained positive outcomes for adults with SMI, it could potentially be scaled up more broadly across Australia, addressing the inequity and lack of comprehensive treatment that many individuals with SMI experience.

ETHICS AND DISSEMINATION

This study has been approved by the Tasmanian Health and Medical Human Research Ethics Committee. The findings will be disseminated to participants and staff who delivered the intervention, submitted for publication in a peer-reviewed journal and shared at academic conferences.

Improved Rehabilitation Outcomes for Persons With and Without Problematic Substance Use After 2 Years With Assertive Community Treatment-A Prospective Study of Patients With Severe Mental Illness in 12 Norwegian ACT Teams

Background: Persons with severe mental illness often face difficulties in accessing and receiving adequate services enabling them to live independently. Many have co-occurring substance use problems that increase the risk of adverse outcomes. Community-based service models have been implemented around the world, including assertive community treatment (ACT), but the knowledge of rehabilitation outcomes in different subgroups is limited. We aimed to explore rehabilitation outcomes among patients suffering severe mental illness with and without substance use problems who had received ACT services for at least 2 years. Additionally, we compared differences in changes between the two groups. Methods: A total of 142 patients who received services for 2 years from the first 12 Norwegian ACT teams were included. Eighty-four (59%) had problematic substance use, while 58 (41%) did not. Data regarding housing, activity, symptoms, functioning, and subjective quality of life were collected upon enrollment into ACT and at 2 years of follow-up. Clinician-rated scales and self-report questionnaires were used. Changes within the two groups and differences in change between the groups were assessed using generalized linear mixed models. Results: Both groups were more likely to have good housing, higher level of functioning, and less anxiety and depressive symptoms after 2 years. The odds of good housing among participants with problematic substance use increased only after adjusting for age and gender. Participants with problematic substance use had less severe symptoms, particularly negative and manic symptoms, while participants without problematic substance use reported improved satisfaction with life in general. Neither group experienced a change in having a meaningful daily activity, positive symptoms, practical and social functioning, or subjective quality of life. The reduction of manic symptoms in the substance use group was the only difference between the groups. Conclusion: After 2 years, patients with and without problematic substance use experienced improvements in several important domains. Furthermore, the improvements were similar in both groups for most outcomes. This may suggest that ACT has a place in the continued effort toward integrated and comprehensive community services empowering patients with severe mental illness to achieve and sustain an independent life, including marginalized groups with severe substance use.

Psychosocial interventions for people with both severe mental illness and substance misuse

BACKGROUND

Even low levels of substance misuse by people with a severe mental illness can have detrimental effects.

OBJECTIVES

To assess the effects of psychosocial interventions for reduction in substance use in people with a serious mental illness compared with standard care.

SEARCH METHODS

The Information Specialist of the Cochrane Schizophrenia Group (CSG) searched the CSG Trials Register (2 May 2018), which is based on regular searches of major medical and scientific databases.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) comparing psychosocial interventions for substance misuse with standard care in people with serious mental illness.

DATA COLLECTION AND ANALYSIS

Review authors independently selected studies, extracted data and appraised study quality. For binary outcomes, we calculated standard estimates of risk ratio (RR) and their 95% confidence intervals (CIs) on an intention-to-treat basis. For continuous outcomes, we calculated the mean difference (MD) between groups. Where meta-analyses were possible, we pooled data using a random-effects model. Using the GRADE approach, we identified seven patient-centred outcomes and assessed the quality of evidence for these within each comparison.

MAIN RESULTS

Our review now includes 41 trials with a total of 4024 participants. We have identified nine comparisons within the included trials and present a summary of our main findings for seven of these below. We were unable to summarise many findings due to skewed data or because trials did not measure the outcome of interest. In general, evidence was rated as low- or very-low quality due to high or unclear risks of bias because of poor trial methods, or inadequately reported methods, and imprecision due to small sample sizes, low event rates and wide confidence intervals. 1. Integrated models of care versus standard care (36 months) No clear differences were found between treatment groups for loss to treatment (RR 1.09, 95% CI 0.82 to 1.45; participants = 603; studies = 3; low-quality evidence), death (RR 1.18, 95% CI 0.39 to 3.57; participants = 421; studies = 2; low-quality evidence), alcohol use (RR 1.15, 95% CI 0.84 to 1.56; participants = 143; studies = 1; low-quality evidence), substance use (drug) (RR 0.89, 95% CI 0.63 to 1.25; participants = 85; studies = 1; low-quality evidence), global assessment of functioning (GAF) scores (MD 0.40, 95% CI -2.47 to 3.27; participants = 170; studies = 1; low-quality evidence), or general life satisfaction (QOLI) scores (MD 0.10, 95% CI -0.18 to 0.38; participants = 373; studies = 2; moderate-quality evidence). 2. Non-integrated models of care versus standard care There was no clear difference between treatment groups for numbers lost to treatment at 12 months (RR 1.21, 95% CI 0.73 to 1.99; participants = 134; studies = 3; very low-quality evidence). 3. Cognitive behavioural therapy (CBT) versus standard care There was no clear difference between treatment groups for numbers lost to treatment at three months (RR 1.12, 95% CI 0.44 to 2.86; participants = 152; studies = 2; low-quality evidence), cannabis use at six months (RR 1.30, 95% CI 0.79 to 2.15; participants = 47; studies = 1; very low-quality evidence) or mental state insight (IS) scores by three months (MD 0.52, 95% CI -0.78 to 1.82; participants = 105; studies = 1; low-quality evidence). 4. Contingency management versus standard care We found no clear differences between treatment groups for numbers lost to treatment at three months (RR 1.55, 95% CI 1.13 to 2.11; participants = 255; studies = 2; moderate-quality evidence), number of stimulant positive urine tests at six months (RR 0.83, 95% CI 0.65 to 1.06; participants = 176; studies = 1) or hospitalisations (RR 0.21, 95% CI 0.05 to 0.93; participants = 176; studies = 1); both low-quality evidence. 5. Motivational interviewing (MI) versus standard care We found no clear differences between treatment groups for numbers lost to treatment at six months (RR 1.71, 95% CI 0.63 to 4.64; participants = 62; studies = 1). A clear difference, favouring MI, was observed for abstaining from alcohol (RR 0.36, 95% CI 0.17 to 0.75; participants = 28; studies = 1) but not other substances (MD -0.07, 95% CI -0.56 to 0.42; participants = 89; studies = 1), and no differences were observed in mental state general severity (SCL-90-R) scores (MD -0.19, 95% CI -0.59 to 0.21; participants = 30; studies = 1). All very low-quality evidence. 6. Skills training versus standard care At 12 months, there were no clear differences between treatment groups for numbers lost to treatment (RR 1.42, 95% CI 0.20 to 10.10; participants = 122; studies = 3) or death (RR 0.15, 95% CI 0.02 to 1.42; participants = 121; studies = 1). Very low-quality, and low-quality evidence, respectively. 7. CBT + MI versus standard care At 12 months, there was no clear difference between treatment groups for numbers lost to treatment (RR 0.99, 95% CI 0.62 to 1.59; participants = 327; studies = 1; low-quality evidence), number of deaths (RR 0.60, 95% CI 0.20 to 1.76; participants = 603; studies = 4; low-quality evidence), relapse (RR 0.50, 95% CI 0.24 to 1.04; participants = 36; studies = 1; very low-quality evidence), or GAF scores (MD 1.24, 95% CI -1.86 to 4.34; participants = 445; studies = 4; very low-quality evidence). There was also no clear difference in reduction of drug use by six months (MD 0.19, 95% CI -0.22 to 0.60; participants = 119; studies = 1; low-quality evidence).

AUTHORS' CONCLUSIONS

We included 41 RCTs but were unable to use much data for analyses. There is currently no high-quality evidence to support any one psychosocial treatment over standard care for important outcomes such as remaining in treatment, reduction in substance use or improving mental or global state in people with serious mental illnesses and substance misuse. Furthermore, methodological difficulties exist which hinder pooling and interpreting results. Further high-quality trials are required which address these concerns and improve the evidence in this important area.

The Role of Illness Identity in Assertive Community Treatment

Assertive community treatment (ACT) provides comprehensive clinical services, including vocational rehabilitation, to individuals with psychiatric disorders for which traditional community mental health services are insufficient. ACT is an evidence-based intervention yielding many positive outcomes, yet service recipients continue to struggle with workforce involvement. The purpose of this study is to determine whether internalized stigma, psychiatric hospitalization, and psychiatric symptoms are associated with work-related self-efficacy among ACT service recipients. A total of 72 individuals with severe mental illness were recruited from ACT programs in three counties in a Mid-Atlantic state. Multiple linear regression was conducted to examine the relationship between work-related self-efficacy and the independent variables of internalized stigma, psychiatric hospitalization, and psychiatric symptoms. Higher internalized stigma scores were negatively associated with work-related self-efficacy (β = −.31, t = −2.32, p < .05), while psychiatric hospitalization in the past year was positively associated with work-related self-efficacy (β = .22−.27, t = −2.13, p < .05). Findings from this study suggests internalized stigma to be an important recovery variable requiring the attention of ACT team members when preparing individuals for work, while countering the assumption that recent hospitalization is a barrier to work-related self-efficacy.

Identifying patterns in psychiatric hospital stays with statistical methods: towards a typology of post-deinstitutionalization hospitalization trajectories

PURPOSE

Over the past 50 years, deinstitutionalization changed the face of psychiatry. However, outpatient treatment in the community does not always fit the needs of those who left institutions and sometimes leads to frequent re-hospitalizations, a mechanism known as the "revolving door" phenomenon. The study aim was to identify different typologies of hospitalization trajectories.

METHODS

Records of 892 inpatients from the Department of Psychiatry of Lausanne University Hospital were analyzed over a 3-year period with discrete sequential-state analysis.

RESULTS

Trajectories could be split between atypical users (4.9% of patients totalling 30.6% of hospital days) and regular users. Within the atypical users group, three categories were identified: "Permanent stays" (3 patients totalling 6.3% of hospital days), "long stays" (1.7% patients/8.6% hospital days) and "revolving door" stays (2.9% patients/15.8% hospital days). The remaining 95.1% of the patients were classified into "unique episodes" (70.0% patients/24.5% hospital days) and "repeated episodes" (25.0% patients/44.9% hospital days). Diagnoses of schizophrenia were overrepresented among heavy users.

CONCLUSIONS

Most patients went through a unique or low number of brief hospital admissions over the 3 years of the study. While the shift of previously institutionalized individuals towards high users of psychiatric hospital seems limited, this phenomenon should not be neglected since 4.9% of patients use about a third of hospital beds. Early identification of problematic profiles could allow the implementation of relapse prevention strategies and facilitate the development of alternatives to hospitalization such as assertive community treatment or housing first programs.

Assertive community treatment versus standard treatment for severely mentally ill patients in Denmark: a quasi-experimental trial

BACKGROUND

The future of assertive community treatment is uncertain, and studies have questioned whether it continues to provide a more effective treatment model for severely mentally ill patients in a modern mental health context. Studies conducted in new settings can contribute to the debate.

METHODS

This Danish study compares treatment from assertive community treatment with treatment by standard community mental health teams, using a non-blinded quasi-experimental multi-center trial. Outcomes included contact with mental health services, days of admission, days of involuntary admission, number of outpatient contacts, adherence to antipsychotic medication, social functioning, user satisfaction, and psychopathology.

RESULTS

A total of 366 patients receiving treatment from assertive community treatment (n = 213) or continuation of care from community mental health teams (n = 153) were included in the trial. Assertive community treatment was significantly better in sustaining contact with patients. At 2-year follow-up, 16 (8%) of patients receiving assertive community treatment versus 22(14%) receiving care from standard treatment had lost contact with treatment. Patients who received assertive community treatment had a larger reduction in inpatient service-use, increased adherence to antipsychotic medication, improved social functioning, and higher user satisfaction. No differences in days of involuntary admission and psychopathology were found.

CONCLUSIONS

The results suggest that a high fidelity assertive community treatment may be a valuable tool to strengthen contact between severely mentally ill patients and the treatment staff and may contribute to improving outcomes in a modern Danish mental health context.

How clinicians make decisions about CTOs in ACT: a qualitative study

BACKGROUND

The first 12 Norwegian assertive community treatment (ACT) teams were piloted from 2009 to 2011. Of the 338 patients included during the teams' first year of operation, 38% were subject to community treatment orders (CTOs). In Norway as in many other Western countries, the use of CTOs is relatively high despite lack of robust evidence for their effectiveness. The purpose of the present study was to explore how responsible clinicians reason and make decisions about the continued use of CTOs, recall to hospital and the discontinuation of CTOs within an ACT setting.

METHODS

Semi-structured interviews with eight responsible clinicians combined with patient case files and observations of treatment planning meetings. The data were analysed using a modified grounded theory approach.

RESULTS

The participants emphasized that being part of a multidisciplinary team with shared caseload responsibility that provides intensive services over long periods of time allowed for more nuanced assessments and more flexible treatment solutions on CTOs. The treatment criterion was typically used to justify the need for CTO. There was substantial variation in the responsible clinicians' legal interpretation of dangerousness, and some clinicians applied the dangerousness criterion more than others.

CONCLUSIONS

According to the clinicians, many patients subject to CTOs were referred from hospitals and high security facilities, and decisions regarding the continuation of CTOs typically involved multiple and interacting risk factors. While patients' need for treatment was most often applied to justify the need for CTOs, in some cases the use of CTOs was described as a tool to contain dangerousness and prevent harm.

Involuntary admission in Norwegian adult psychiatric hospitals: a systematic review

Background

It is an important objective of the psychiatric services to keep the use of involuntary procedures to a minimum, as the use of coercion involves clinical, ethical, and legal issues. It has been claimed that Norway has a relatively high rate of involuntary admissions. We reviewed the peer-reviewed literature on the use of involuntary admission in Norway, with the purpose of identifying the current state of knowledge and areas in need of further research.

Methods

A systematic review following the PRISMA statement was conducted. We searched the electronic databases PsycInfo, PubMed, Web of Science, CINAHL, and Embase for studies relating to involuntary admission to Norwegian adult psychiatric hospitals published in the period 1 January 2001 to 8 August 2016. The database searches were supplemented with manual searches of relevant journals, reference lists, and websites.

Results

Seventy-four articles were included and grouped into six categories based on their main topics: Patients’ experiences, satisfaction and perceived coercion (21 articles), the Referral and admission process (11 articles), Rates of admission (8 articles), Characteristics of the patients (17 articles), Staff attitudes (9 articles), and Outcomes (8 articles). Four of the included articles described intervention studies. Fifty-seven of the articles had a quantitative design, 16 had a qualitative design, and one a mixed-method design. There was a broad range of topics that were studied and considerable variation in study designs. The findings were largely in line with the international literature, but the particularities of Norwegian legislation and the Norwegian health services were reflected in the literature. The four intervention studies explored interventions for reducing rates of involuntary admission, such as modifying referring routines, improving patient information procedures, and increasing patients’ say in the admission process, and represent an important avenue for future research on involuntary admission in Norway.

Conclusions

The review suggests that Norway has a relatively high rate of involuntary admissions. The identified studies represent a broad mix of topics and designs. Four intervention studies were identified. More studies with strong designs are needed to bring research on involuntary admission in Norway to a next level.

The impact of substance use disorders on clinical outcomes in older-adult psychiatric inpatients

OBJECTIVE

To examine associations among substance use disorder (SUD) and measures of length of stay (LOS) and non-psychiatric medical comorbidity (MEDCO) in older-adult inpatients with serious mental illness (SMI), hypothesizing SUD would be related to worse clinical outcomes.

METHODS

A cross-sectional study analyzed medical records from 2010 to 2016 of 7258 inpatients with SMI ≥ age 50, obtained from a 274-bed psychiatric hospital. Descriptive analyses examined prevalence rates for SUD status (+/-), individual drug classes, and total number of SUDs (polysubstance use disorders). Regression models examined the influence of 2 independent variables of interest: (1) SUD status (+/-) and (2) type of SUD (ie, specific drug), controlling for demographic factors and additional (non-SUD) psychiatric disorders. Two dependent (outcome) variables were examined: LOS and MEDCO.

RESULTS

The overall SUD rate was 26%; cocaine was the most common SUD (≈ 10%). SUD status and additional (non-SUD) psychiatric diagnoses were significantly associated with longer LOS (both P < 0.001). For individual SUDs, cocaine, marijuana, opiates, and alcohol were all significantly associated with LOS (all P < 0.01). SUD status, age, sex, admission status, and race were significantly associated with MEDCO (all P < 0.002). For individual SUDs, barbiturates, opiates, and alcohol were all significantly associated with MEDCO (P < 0.01).

CONCLUSIONS

The prevalence of SUD in this sample underscores concerns related to treating older adults presenting providers with comorbid SUD and SMI. This combination may increase the burden and complexity of care, warranting further investigation into mechanisms and long-term consequences.

Delirium tremens and alcohol withdrawal nationally in the Veterans Health Administration

BACKGROUND AND OBJECTIVES

Alcohol withdrawal-especially delirium tremens (DT)-is a potentially life-threatening condition. While short-term treatment regimens and factors that predispose to more severe symptomatology have been extensively studied, little attention has been paid to the clinical epidemiology and long-term care of the chronic medical, addictive, psychiatric, and psychosocial problems faced by these patients.

METHODS

National Veterans Health Administration data from fiscal year 2012 were examined to identify veterans diagnosed with DT; with withdrawal but not DT (WNDT); and with Alcohol Use Disorder (AUD) but neither DT nor WNDT. They were compared on sociodemographic characteristics, psychiatric and medical co-morbidities, and health service and psychotropic medication use, first with bivariate analyses and then multiple logistic regression.

RESULTS

Among the 345,297 veterans diagnosed with AUD, 2,341 (0.7%) were diagnosed with DT and 6,738 (2.0%) with WNDT. Veterans diagnosed with either WNDT or DT were more likely to have been homeless, had more comorbid medical and psychiatric disorders, were more likely to be diagnosed with drug use disorders, utilized more health services, received more psychotropic medications, and were more likely to receive naltrexone. They were more likely to receive specialized legal, housing, vocational, and psychosocial rehabilitation services, as well as intensive case management.

CONCLUSIONS

Adults with WNDT and DT suffer from multiple chronic conditions and long-term service models are needed to coordinate the work of multiple specialists and to assure continuity of care.

SCIENTIFIC SIGNIFICANCE

This national study identifies sociodemographic characteristics, comorbidities, and service utilization patterns associated with WNDT and DT.(Am J Addict 2017;26:722-730).
