Assertive community treatment in the Netherlands: a randomized controlled trial

Difficult-to-Engage Patients with Severe Mental Illness in Rural Community Settings: Results of the Greek Hybrid Assertive Community Treatment Model of Mental Healthcare

Background: Modified Assertive Community Treatment (ACT) in rural settings may be effective in the care of patients with severe mental illness (SMI) that are difficult to engage in community care. The objective of the present study was to explore the impact of the care by a hybrid ACT team on SMI patients' hospitalizations, length of hospital stay, symptomatology and functioning in a rural community treatment setting in Greece. Methods: The hybrid ACT team is an expansion of the services of the well-established generic Mobile Mental Health Unit in a rural area of Northwest Greece, and delivers home-based care for patients with SMI. This was a 3-year prospective, mirror image, pre-post observational study. Patients' symptomatology, functioning and general outcome were measured with the use of the Brief Psychiatric Rating Scale (BPRS), the Global Assessment of Functioning Scale (GAF), and the Health of the Nation Outcome Scale (HοNOS). Results: The mean age of the 23 enrolled patients was 52.4 years and the mean age of disease onset was 23.5 years, with a mean number of hospitalizations 10.74. Over the 16-month follow-up patients' hospitalizations, both voluntary and involuntary, had been significantly reduced by almost 80%. Length of hospital stay had been significantly reduced by 87%, whereas patients' functioning and symptomatology had been significantly improved, by 17% and 14.5%, respectively. Conclusions: The model of hybrid ACT in rural areas in Greece may be effective in the treatment of difficult-to-engage patients with SMI and may improve patients' outcomes.

Service users' perceptions of relevant and helpful components of an integrated care concept (ACCESS) for psychosis

Introduction

Psychotic disorders have a significant impact on patients' lives and their families, and long-term treatment with individually tailored multimodal combinations of therapies is often required. Integrated care (IC) concepts such as the "Hamburg Model (ACCESS)" with a focus on psychotic disorders, includes different (therapeutic) components with pharmaco- and psychotherapy, family involvement, home treatment and the option of using a 24/7 crisis hotline. All components are offered by a therapeutically-oriented assertive community treatment (TACT) team in a need-adapted manner. So far, however, little is known about which specific components are regarded as especially relevant and helpful by the users of IC.

Methods

Patients currently participating in IC completed a questionnaire as part of the continuous quality assurance study (ACCESS II) in which they were asked to rate the different components of treatment according to their relevance and helpfulness, considering the individual's unique experiences with IC and needs in mental health care. Furthermore, they were asked to make suggestions regarding additional helpful components of treatment.

Results

Fifty patients participated in this survey (23% of the patients currently participating in the IC concept). For participants, the most helpful and important factors were having the same therapist in the long-term and the 24/7 crisis telephone. Additional components suggested by patients included more addiction-specific therapies and increased focus on vocational rehabilitation and integration.

Conclusion

From the perspective of the users of IC, long-term care from a trusted therapist with whom there is a therapeutic relationship and the possibility to reach someone they already know from the TACT team 24/7 serves as the best basis for effective care, fostering trust, understanding, and open communication. In contrast, home treatment remains a relevant aspect of evidence-based care for people with severe mental illness, but perhaps surprisingly, is not viewed as the most important issue.

Patient Outcomes of Flexible Assertive Community Treatment Compared With Assertive Community Treatment

OBJECTIVE

In many European countries, flexible assertive community treatment (FACT) has replaced assertive community treatment (ACT) despite limited evidence for FACT's effectiveness in improving functional and patient-reported outcomes. This study evaluated the effectiveness of FACT relative to ACT in improving functioning, client satisfaction, and the working alliance.

METHODS

The authors used a nonblinded, quasi-experimental controlled study design to compare outcomes of patients treated by ACT teams that were reconfigured to FACT teams with those of patients treated by a remaining ACT team. Patients from nine ACT teams in the Capital Region of Denmark were included. Six of the nine ACT teams were reconfigured to FACT in 2018 and 2019 by integrating them with community mental health teams. The remaining three ACT teams were used as control groups. Assignment to treatment was based solely on administrative considerations.

RESULTS

The study included 131 patients (FACT, N=74; ACT, N=57). Patients treated by FACT teams had poorer personal and social functioning than patients assigned to ACT teams (adjusted difference in means=-2.9, 95% CI=-5.8 to -0.1). No between-group differences were found in client satisfaction or working alliance.

CONCLUSIONS

Patients treated by FACT teams had significantly lower functioning than patients treated by ACT teams, but the clinical relevance or causality of this finding remains unclear. Given the reconfiguration of the FACT teams during follow-up, along with substantial drop-out rates and baseline differences between the two groups, these results must be interpreted with caution. The findings require further examination in a randomized controlled trial that includes fidelity measures of the treatment models.

Psychosocial Interventions for Adults With Schizophrenia: An Overview and Update of Systematic Reviews

OBJECTIVE

The authors of this systematic review (SR) sought to provide evidence for effects of commonly used psychosocial interventions on several outcomes among adults with schizophrenia.

METHODS

MEDLINE, the Cochrane Library, and PsycINFO databases were searched through July 2020. Eligible studies were SRs and trials of at least 12 weeks duration and with ≥50 participants that compared psychosocial interventions with treatment as usual among adults with schizophrenia. Study design, year, setting, country, sample size, eligibility criteria, population, clinical and intervention characteristics, results, and funding source were extracted, along with quality criteria. The evidence was evaluated on quality and strength of evidence stratified by intervention area and outcome, according to the Evidence-Based Practice Centers Methods Guide of the Agency for Healthcare Research and Quality.

RESULTS

Nine SRs and 30 trials (N=23,921 patients) in 11 intervention areas were included. Trials were mostly of fair quality and had low-to-moderate strength of evidence. Compared with treatment as usual, most psychosocial interventions were more effective in improving intervention-targeted outcomes, including core illness symptoms. Compared with treatment as usual, assertive community treatment, cognitive-behavioral therapy (CBT), family interventions, psychoeducation, social skills training, supported employment, and early interventions for first-episode psychosis (FEP) improved various functional outcomes. CBT and early interventions for FEP improved quality of life. Family interventions, psychoeducation, illness self-management, and early interventions for FEP reduced relapse.

CONCLUSIONS

Compared with treatment as usual, most psychosocial interventions improved functional outcomes, quality of life, and core illness symptoms, and several reduced relapse frequency among adults with schizophrenia.

The Greek Hybrid Version of the Assertive Community Treatment Model: A Perspective View between Challenges and Limitations

The Assertive Community Treatment (ACT) model of care has been long considered to be effective in the management of patients with severe mental illness (SMI) in most Western countries. The implementation of the original ACT model may be particularly challenging in rural and remote communities with small and dispersed populations and lack of adequate mental health services. Rural programs may have to adapt the model and modify the ACT fidelity standards to accommodate these limitations, and this is the rationale for the introduction of more flexible, hybrid ACT models. In rural Greece, the so called Mobile Mental Health Units (MMHUs) are well-established community mental health services. For patients with SMI that have difficulties engaging with treatment services, the new hybrid ACT model has been recently launched. The objective of this manuscript is to present the recently launched hybrid ACT model in rural areas in Greece and to explore the challenges and limitations in its implementation from the experience of a team of mental health professionals with ACT experience. Referral criteria have not been strictly set, but the number of previous relapses and hospitalizations is taken under consideration, as well as the history of poor treatment adherence and disengagement from mental health services. The main limitation in the implementation of the hybrid ACT service is that it has been introduced in several areas in the absence of a pre-existing community mental health service. This may impact referrals and limit focus on the difficult cases of patients with SMI, thus making the evaluation of the model inapplicable.

[Difficult-to-engage patients: What evolution after discharge from Assertive Community Programs?]

OBJECTIVES

Beneficial effects of Assertive Community Treatment (ACT) programs on patients with severe mental disorders are well established over short or medium term. However, studies that investigate long term clinical and psychosocial outcomes are remarkably scarce, and it is not known whether the support and intensive care delivered by these programs maintain their benefits over time, especially after discharge. Thus, the present study sought further understanding on this issue by evaluating long term clinical and psychosocial evolution of patients who had been treated by an ACT team in 2007. We investigated the nature of treatment interventions and the level of care since discharge from ACT, especially in terms of adherence to care and number of psychiatric hospitalizations. We also examined factors, at inclusion in the ACT program and after six months of treatment, that could predict better long-term outcomes.

METHODS

Twenty-nine patients with severe mental disorders, characterized by the heavy use of inpatient facilities and refusal of care, were treated by an ACT team which was implmented between 2007 and 2009. They participated at that time in an initial study on the effect of the program and were therefore assessed at inclusion and again after six months of treatment. Between 2016 and 2017, the present follow up took place and patients were assessed again on their current psychosocial functioning, quality of life and intensity of symptoms, using the same scales as those administered in the initial study. This design allowed us to compare baseline with "early" (after six months) and "late" (after a mean of 8.7 years) effects of ACT program on patients. In order to assess adherence to care since discharge from ACT, data on nature and level of psychiatric treatment was systematically reviewed, including all public and private inpatient and outpatient treatments since the end of the ACT program.

RESULTS

Detailed tables on hospitalizations before, during and after ACT treatment are reported, as well as tables summarizing the level of care and nature of treatment since discharge from ACT. During the mean of 8.7 years of evolution and 6.3 years after discharge from ACT, these patients, characterized by severe mental disorders, heavy use of inpatient facilities and refusal of care, sustained a reduced rate of hospitalizations and a minor rate of disengagement from outpatient care (6.9 %). Both severity of symptoms, poorer quality of life and worst functioning in the community at inclusion (baseline) as well as early improvements (after six month of ACT treatment) of the same outcomes were significantly associated with long term improvements. Results also show other baseline predictors of long term improvement: fewer years since disorder onset was associated with improvement of functioning in the community; further advancement in the recovery process predicted better enhancement in quality of life, and a better initial functioning in the community was associated with a better improvement of symptomatology.

CONCLUSIONS

This study provides insight on the sustainability of the benefits of ACT programs, suggesting that these interventions can help patients who are refractory to care to gain clinical and psychosocial improvement in the long term. Our results also suggest that baseline severity as well as early improvements after six months of treatment were associated with larger improvement at follow up. These clinical predictors provide some help to distinguish which patients are more likely to benefit from an ACT approach.

Investigating the critical elements and psychosocial outcomes of Youth Flexible Assertive Community Treatment: a study protocol for an observational prospective cohort study

INTRODUCTION

When adolescents experience complex psychiatric and social problems, numerous healthcare services usually become involved. In these cases, fragmentation of care services is a risk that often results in both ineffective care and in patients disengaging from care services. To address these issues, Youth Flexible Assertive Community Treatment (Youth Flexible ACT) was developed in the Netherlands. This client-centred service delivery model aims to tackle the fragmented care system by providing psychiatric treatment and support in a flexible and integrated manner. While Youth Flexible ACT is gaining in popularity, the effectiveness of the care model remains largely unexamined.

METHODS AND ANALYSIS

Here, we present an observational prospective cohort (2017-2021) in which a broad range of treatment outcomes will be monitored. The primary aim of the study is to examine change in treatment outcomes over the course of the Flexible ACT care. The secondary aim is to examine the association between (elements of) Youth Flexible ACT model fidelity and treatment outcomes. An estimated total number of 200 adolescents who receive care from one of the 16 participating Youth Flexible ACT teams will be included in the study. Participants will be asked to complete assessments at four time points in 6-month intervals, resulting in a study duration of 18 months. Latent growth curve analysis will be conducted to examine change in psychosocial functioning over time and its relation to model fidelity.

ETHICS AND DISSEMINATION

This study received ethical approval from Trimbos Ethics Committee (201607_75-FACT2). This approval applies for all participating institutions. The results of the study will be reported in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology statement. Results will be disseminated via peer-reviewed academic journals and presentations at conferences. In addition, results will be made available for participating sites, funders and researchers.

Assertive Community Programs for Patients with Severe Mental Disorders: Are Benefits Sustained After Discharge?

The benefits of assertive community treatment (ACT) on patients with severe mental disorders are well established over short or medium term. However, studies that investigate long term outcomes are remarkably scarce. Thus, this study aimed to evaluate patient's long term clinical and psychosocial evolution after discharge from ACT. An assessment was conducted on 29 patients characterized by inpatient facilities heavy use and refusal of care, who were included in an ACT program 8.7 (SD = 0.7) years ago and discharged 6.3 (SD = 1.8) years ago. Results of the follow up showed decreased rates of hospitalizations and symptomatology, as well as sustained improvement in adherence to care, in quality of life and in social functioning. This data suggests that ACT programs can help refractory to care patients to gain clinical and psychosocial improvement and lay foundation for better long-term adherence to care. Results also suggest that ACT didn't imply a lifetime treatment.

Model fidelity and team members' experiences of assertive community treatment in Norway: a sequential mixed-methods study

Background

Assertive community treatment (ACT) is an evidence-based treatment for people with severe mental illness, and this model is used widely throughout the world. Given the various adaptations in different contexts, we were interested in studying the implementation and adaptation of the ACT model in Norway. The first 12 Norwegian ACT teams were established between 2009 and 2011, and this study investigated the teams' model fidelity and the team members' experiences of working with ACT.

Methods

To investigate implementation of the ACT model, fidelity assessments were performed 12 and 30 months after the teams started their work using the Tool for Measurement of Assertive Community Treatment (TMACT). Means and standard deviations were used to describe the ACT teams' fidelity scores. Cohen's effect size d was used to assess the changes in TMACT scores from the first to second assessment. Qualitative focus group interviews were conducted in the 12 teams after 30 months to investigate the team members' experiences of working with the ACT model.

Results

The fidelity assessments of the Norwegian teams showed high implementation of the structural and organizational parts of the ACT model. The newer parts of the model, the recovery and evidence-based practices, were less implemented. Four of the six subscales in TMACT improved from the first to the second assessment. The team members experienced the ACT model to be a good service model for the target population: people with severe mental illness, significant functional impairment, and continuous high service needs. Team members perceived some parts of the model difficult to implement and that it was challenging to find effective ways to collaborate with existing health and social services.

Conclusion

The first 12 Norwegian ACT teams implemented the ACT model to a moderate degree. The ACT model could be implemented in Norway without extensive adaptations. Although the team members were satisfied with the ACT model, especially the results for their service users, inclusion of the ACT team to the existing service system was perceived as challenging.

Optimization of Antipsychotic and Benzodiazepine Drugs in Patients with Severe Mental Disorders in an Intensive Case Management Program

The Intensive Case Management (ICM) model is a community-based program for people with severe mental illness that may reduce hospitalization and increase retention in care. The aims of this study were to analyze changes in the antipsychotic and benzodiazepine dosage in 106 patients who participated in an Individualized Service Program based on the ICM model for at least 6 months and to assess the change in the number of patients taking a high or very high dose of an antipsychotic drug and the number receiving antipsychotic polytherapy. Both the average daily dose of antipsychotic and benzodiazepine drugs and the number of patients with high doses of antipsychotic and more than one antipsychotic drug decreased significantly. Implementing the ICM program in patients with severe mental illness could help to decrease adverse drug effects and health care expenditures.

Clinical significance of assertive community treatment among adolescents

PURPOSE

The efficacy of assertive community treatment for children and adolescents is proven in the United States, but remains controversial in Europe. Moreover, most studies showing positive outcomes of assertive community treatment are limited to statistically significant differences and do not consider whether the treatment is also subjectively clinically meaningful for the patient. Using a naturalistic sample, the present study aims to assess statistical and clinical significance of an assertive community treatment unit for adolescents in Europe.

METHODS

Linear mixed-effects models and reliable change indices were used to respectively assess the statistical and clinical significance of assertive community treatment in 179 adolescents (mean age = 15.76, SD = 1.76) with severe mental illnesses.

RESULTS

Difficulties related to mental health (measured by the Health of the Nation Outcome Scales for Children and Adolescents, HoNOSCA) and overall functioning (measured by the Global Assessment of Functioning scale) statistically improved (all ps < 0.001) from admission to discharge. Additionally, a considerable proportion of patients (from 14% to 21%) clinically recovered to functional levels.

CONCLUSION

Our results support the fact that assertive community treatment can have convincing and positive clinical outcomes in European settings.

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.

Reduction of Involuntary Admissions in Patients With Severe Psychotic Disorders Treated in the ACCESS Integrated Care Model Including Therapeutic Assertive Community Treatment

Objective: The ACCESS treatment model offers assertive community treatment (ACT) embedded in an integrated care program to patients with severe psychotic disorders. Compared to standard care, it proved to be more effective in terms of service disengagement and other outcomes in patients with psychotic disorders over 12, 24, and 48 months. Many patients with severe mental disorders experience involuntary admissions which can be potentially traumatic. In this study, we assessed the effect of ACT on reducing involuntary admissions over an observation period of 4 years. Method: One hundred seventy-one patients treated in ACCESS were included in this study. The primary outcome was rate of involuntary admissions during 48 months. Secondary outcomes were differences between those with and without involuntary admissions in the 2 years prior to ACCESS regarding change of psychopathology, severity of illness, psychosocial functioning, quality of life, satisfaction with care, medication non-adherence, and service-disengagement. Results: Of 171 patients, 58 patients (33.9%) were involuntarily admitted to hospital in the past 2 years before entry. During the 4 years of treatment, 16 patients (9.4%) were involuntarily admitted to hospital which was a significantly lower rate compared to the 2 years before inclusion in ACCESS (p < .001). Comparing the two groups, larger improvements in severity of illness (p = .004) and functional status (p = .043) were detected in the group with no history of involuntary admissions. At 4-year follow-up, of the remaining patients, 69.2% (n = 81) were full adherent (p < .001), compared to 18.9% (n = 31) at baseline with no differences between the two groups over the study period (p = .25). Over 4 years, only 13 patients (13.2%) were service-disengaged due to non-practical reasons. Conclusions: In this long-term study, we were able to demonstrate a reduction in involuntary admissions in four treatment years compared to the 2 years prior to admission to the ACCESS model in patients with severe and mostly multiphase schizophrenia spectrum disorders and affective disorders with psychotic features. This may help prevent patients from suffering from a potentially traumatic experience during treatment in the psychiatric system.

Effectiveness of integrated care including therapeutic assertive community treatment in severe schizophrenia-spectrum and bipolar I disorders: Four-year follow-up of the ACCESS II study

The ACCESS-model offers integrated care including assertive community treatment to patients with psychotic disorders. ACCESS proved more effective compared to standard care (ACCESS-I study) and was successfully implemented into clinical routine (ACCESS-II study). In this article, we report the 4-year outcomes of the ACCESS-II study. Between May 2007 and December 2013, 115 patients received continuous ACCESS-care. We hypothesized that the low 2-year disengagement and hospitalization rates and significant improvements in psychopathology, functioning, and quality of life could be sustained over 4 years. Over 4 years, only 10 patients disengaged from ACCESS. Another 23 left for practical reasons and were successfully transferred to other services. Hospitalization rates remained low (13.0% in year 3; 9.1% in year 4). Involuntary admissions decreased from 35% in the 2 years prior to ACCESS to 8% over 4 years in ACCESS. Outpatient contacts remained stably high at 2.0–2.4 per week. We detected significant improvements in psychopathology (effect size d = 0.79), illness severity (d = 1.29), level of functioning (d = 0.77), quality of life (d = 0.47) and stably high client satisfaction (d = 0.02) over 4 years. Most positive effects were observed within the first 2 years with the exception of illness severity, which further improved from year 2 to 4. Within continuous intensive 4-year ACCESS-care, sustained improvements in psychopathology, functioning, quality of life, low service disengagement and re-hospitalization rates, as well as low rates of involuntary treatment, were observed in contrast to other studies, which reported a decline in these parameters once a specific treatment model was stopped. Yet, stronger evidence to prove these results is required.

Specialisation and marginalisation: how the assertive community treatment debate affects individuals with complex mental health needs

The growth of specialism in a field can be considered a healthy response to emerging evidence, technology and skills, yet it risks creating unhelpful barriers to collaborative working and fragmented patient pathways. Mental health services in England have experienced this tension in recent years through the national implementation of local specialist community teams that aim to reduce the need for in-patient admission through a focus on crisis resolution, early intervention and assertive community treatment (ACT). In response to the results of studies assessing its effectiveness, there has been disinvestment in ACT. This risks marginalising people with severe and complex mental health problems by depriving them and their families of the intensive support they need for successful community living, as well as discouraging researchers from undertaking further high-quality studies that can inform the intelligent evolution of the ACT model within different contexts.

Disordered lives: Life circumstances and clinical characteristics of very frequent users of emergency departments for primary mental health complaints

This study explored the life circumstances and clinical characteristics of very frequent users of emergency departments (EDs) presenting with a primary mental health complaint. Patients with 10 or more EDs visits in 2012 with a primary psychiatric diagnosis in a Canadian regional health authority were identified from electronic administrative files. The hospital charts for these patients were thoroughly reviewed for a three-year period, from 2011 to 2013. A retrospective thematic analysis was undertaken. Very frequent users of EDs were generally young to early middle aged, unemployed, living in transient accommodations, having substance abuse diagnoses, and self-referred to EDs for a variety of psychiatric and health symptoms and/or unmet needs. Four themes were identified: 1) substance abuse and associated health and social problems; 2) common mental disorders, which may include suicidality; 3) social and personal stressors with additional common mental disorders and somatic complaints; 4) cognitive impairment with concurrent psychiatric disorders. Traditional mental health services are ineffective in dealing with patients with complex psychiatric and social problems/needs. Efforts should focus on early detection, intervention, reducing mental and behavior problems, and developing appropriate case management and treatment options. Personalized care models are needed to meet their diverse needs.

Intensive case management for severe mental illness

BACKGROUND

Intensive Case Management (ICM) is a community-based package of care aiming to provide long-term care for severely mentally ill people who do not require immediate admission. Intensive Case Management evolved from two original community models of care, Assertive Community Treatment (ACT) and Case Management (CM), where ICM emphasises the importance of small caseload (fewer than 20) and high-intensity input.

OBJECTIVES

To assess the effects of ICM as a means of caring for severely mentally ill people in the community in comparison with non-ICM (caseload greater than 20) and with standard community care. We did not distinguish between models of ICM. In addition, to assess whether the effect of ICM on hospitalisation (mean number of days per month in hospital) is influenced by the intervention's fidelity to the ACT model and by the rate of hospital use in the setting where the trial was conducted (baseline level of hospital use).

SEARCH METHODS

We searched the Cochrane Schizophrenia Group's Trials Register (last update search 10 April 2015).

SELECTION CRITERIA

All relevant randomised clinical trials focusing on people with severe mental illness, aged 18 to 65 years and treated in the community care setting, where ICM is compared to non-ICM or standard care.

DATA COLLECTION AND ANALYSIS

At least two review authors independently selected trials, assessed quality, and extracted data. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated mean difference (MD) between groups and its 95% CI. We employed a random-effects model for analyses.We performed a random-effects meta-regression analysis to examine the association of the intervention's fidelity to the ACT model and the rate of hospital use in the setting where the trial was conducted with the treatment effect. We assessed overall quality for clinically important outcomes using the GRADE approach and investigated possible risk of bias within included trials.

MAIN RESULTS

The 2016 update included two more studies (n = 196) and more publications with additional data for four already included studies. The updated review therefore includes 7524 participants from 40 randomised controlled trials (RCTs). We found data relevant to two comparisons: ICM versus standard care, and ICM versus non-ICM. The majority of studies had a high risk of selective reporting. No studies provided data for relapse or important improvement in mental state.1. ICM versus standard careWhen ICM was compared with standard care for the outcome service use, ICM slightly reduced the number of days in hospital per month (n = 3595, 24 RCTs, MD -0.86, 95% CI -1.37 to -0.34,low-quality evidence). Similarly, for the outcome global state, ICM reduced the number of people leaving the trial early (n = 1798, 13 RCTs, RR 0.68, 95% CI 0.58 to 0.79, low-quality evidence). For the outcome adverse events, the evidence showed that ICM may make little or no difference in reducing death by suicide (n = 1456, 9 RCTs, RR 0.68, 95% CI 0.31 to 1.51, low-quality evidence). In addition, for the outcome social functioning, there was uncertainty about the effect of ICM on unemployment due to very low-quality evidence (n = 1129, 4 RCTs, RR 0.70, 95% CI 0.49 to 1.0, very low-quality evidence).2. ICM versus non-ICMWhen ICM was compared with non-ICM for the outcome service use, there was moderate-quality evidence that ICM probably makes little or no difference in the average number of days in hospital per month (n = 2220, 21 RCTs, MD -0.08, 95% CI -0.37 to 0.21, moderate-quality evidence) or in the average number of admissions (n = 678, 1 RCT, MD -0.18, 95% CI -0.41 to 0.05, moderate-quality evidence) compared to non-ICM. Similarly, the results showed that ICM may reduce the number of participants leaving the intervention early (n = 1970, 7 RCTs, RR 0.70, 95% CI 0.52 to 0.95,low-quality evidence) and that ICM may make little or no difference in reducing death by suicide (n = 1152, 3 RCTs, RR 0.88, 95% CI 0.27 to 2.84, low-quality evidence). Finally, for the outcome social functioning, there was uncertainty about the effect of ICM on unemployment as compared to non-ICM (n = 73, 1 RCT, RR 1.46, 95% CI 0.45 to 4.74, very low-quality evidence).3. Fidelity to ACTWithin the meta-regression we found that i.) the more ICM is adherent to the ACT model, the better it is at decreasing time in hospital ('organisation fidelity' variable coefficient -0.36, 95% CI -0.66 to -0.07); and ii.) the higher the baseline hospital use in the population, the better ICM is at decreasing time in hospital ('baseline hospital use' variable coefficient -0.20, 95% CI -0.32 to -0.10). Combining both these variables within the model, 'organisation fidelity' is no longer significant, but the 'baseline hospital use' result still significantly influences time in hospital (regression coefficient -0.18, 95% CI -0.29 to -0.07, P = 0.0027).

AUTHORS' CONCLUSIONS

Based on very low- to moderate-quality evidence, ICM is effective in ameliorating many outcomes relevant to people with severe mental illness. Compared to standard care, ICM may reduce hospitalisation and increase retention in care. It also globally improved social functioning, although ICM's effect on mental state and quality of life remains unclear. Intensive Case Management is at least valuable to people with severe mental illnesses in the subgroup of those with a high level of hospitalisation (about four days per month in past two years). Intensive Case Management models with high fidelity to the original team organisation of ACT model were more effective at reducing time in hospital.However, it is unclear what overall gain ICM provides on top of a less formal non-ICM approach.We do not think that more trials comparing current ICM with standard care or non-ICM are justified, however we currently know of no review comparing non-ICM with standard care, and this should be undertaken.

Outcomes of FLEXIBLE Assertive Community Treatment (FACT) Implementation: A Prospective Real Life Study

This study aimed to investigate social and clinical outcomes and use of care during and after implementation of FLEXIBLE Assertive Community Treatment (ACT). Three teams and 372 patients were involved. Model fidelity, clinical and social assessments were performed at baseline and after 1 and 2 years. Use of care was registered continuously. Model fidelity was good at the end of the study. Data showed much variation between patients in number and duration of ACT periods. Statistically significant improvements were found in compliance, unmet needs and quality of life. Improvement of quality of life and functioning was related to duration of ACT. The percentage of remissions increased with 9 %. The number of admissions, admission days and face to face contacts differed between ACT and non-ACT patients, but generally decreased. Findings suggest that implementation of FACT results in a more flexible adaptation of care to the needs of the patients.

Predictors of Clinical Outcome of Assertive Community Treatment (ACT) in a Rural Area in Denmark: An Observational Study with a Two-Year Follow-Up

Assertive Community Treatment (ACT) is a multidisciplinary team approach to community care treatment, mainly characterised by small caseload and individualised care. The aim of the present study was to identify predictors of clinical outcome in ACT using an observational design. Three ACT Teams were established in The North Denmark Region to treat patients with severe mental illness. The patients were identified and followed in regional and national psychiatric registers, and in social and somatic case registers, 2 years before and 2 years after inclusion. The results showed that the use of psychiatric hospital services decreased significantly for the 240 included patients. Furthermore, the psychopharmacological profile was improved. No significant change occurred in the consumption of the somatic hospitals. Clinical outcome, defined as halving of admissions or bed days, was in a logistic analysis predicted by the patient's psychiatric use of inpatient service prior to inclusion in an ACT Team.

Hospital utilization outcome of an assertive outreach model for schizophrenic patients - results of a quasi-experimental study

We assessed whether an Assertive Outreach (AO) program for patients with schizophrenia implemented in German routine care in rural areas reduces psychiatric hospital admissions and/or psychiatric hospital days. We conducted a quasi-experimental controlled study with 5 assessments in 12 months. Data collection included health care utilization (Client Sociodemographic and Service Receipt Inventory), and clinical parameters. The assessments took place in the practices of the psychiatrists. Admission incidence rates were calculated. For bivariate group comparison, we used U-tests, T-tests and Chi(2)-Tests, multivariate analysis was conducted using zero-inflated regression models. For hospital outcomes, data of 295 patients was analysed. No statistically significant differences between AO and TAU patients in terms of hospital admissions or hospital days were found. Overall hospital utilization was low (8%). Advantages of AO over TAU referring to hospital utilization were not found. However, a spill-over effect might have reduced hospital utilization in both groups. Further research should differentiate patient subgroups. These two appear to be key factors to explain effects or absence of effects and to draw conclusions for the mental health care delivery.

Schizophrenia in the Netherlands: Continuity of Care with Better Quality of Care for Less Medical Costs

Background

Patients with schizophrenia need continuous elective medical care which includes psychiatric treatment, antipsychotic medication and somatic health care. The objective of this study is to assess whether continuous elective psychiatric is associated with less health care costs due to less inpatient treatment.

Methods

Data concerning antipsychotic medication and psychiatric and somatic health care of patients with schizophrenia in the claims data of Agis Health Insurance were collected over 2008–2011 in the Netherlands. Included were 7,392 patients under 70 years of age with schizophrenia in 2008, insured during the whole period. We assessed the relationship between continuous elective psychiatric care and the outcome measures: acute treatment events, psychiatric hospitalization, somatic care and health care costs.

Results

Continuous elective psychiatric care was accessed by 73% of the patients during the entire three year follow-up period. These patients received mostly outpatient care and accessed more somatic care, at a total cost of €36,485 in three years, than those without continuous care. In the groups accessing fewer or no years of elective care 34%-68% had inpatient care and acute treatment events, while accessing less somatic care at average total costs of medical care from €33,284 to €64,509.

Conclusions

Continuous elective mental and somatic care for 73% of the patients with schizophrenia showed better quality of care at lower costs. Providing continuous elective care to the remaining patients may improve health while reducing acute illness episodes.

Hospitalization of high and low inpatient service users before and after enrollment into Assertive Community Treatment teams: a naturalistic observational study

Background

Assertive Community Treatment (ACT) is more successful in reducing hospitalization when baseline use is high. However, with a growing recovery-focus, ACT may be useful for people with severe mental illness who are difficult to engage but not high users of inpatient services. This study investigated hospitalization 2 years before and 2 years after ACT enrollment amongst patients both with and without high inpatient services use before enrollment into ACT.

Methods

This naturalistic observational study included 142 patients from 12 different ACT teams throughout Norway. Of these, 74 (52 %) were high users of inpatient services before ACT. The teams assessed the patients upon enrollment using clinician-rated and self-reported questionnaires. Hospitalization data from 2 years before and 2 years after enrollment into ACT were obtained from the Norwegian Patient Registry. Linear mixed models were used to assess changes in hospitalization and to explore associations between these changes and patient characteristics.

Results

When the participants enrolled into the ACT teams, high users of inpatient care were younger, more often living alone and more often subject to involuntary outpatient treatment than low users. The participants spent significantly fewer days in hospital during the 2 years of ACT follow-up compared to the 2 years before enrollment. The reduction was more evident amongst high users, whereas low users had an initial increase in inpatient days in the first year of ACT and a subsequent decrease in the second year. More severe negative symptoms and previous high use of inpatient care were associated with a reduction in both total and involuntary inpatient days. Additionally, a reduction in involuntary inpatient days was associated with being subject to involuntary outpatient treatment upon enrollment into ACT.

Conclusion

The findings in this study may suggest that ACT contributes to more appropriate use of inpatient care, possibly by reducing the presumably avoidable hospitalization of high users and increasing the presumably needed inpatient care of low users.

Fifteen-month follow up of an assertive community treatment program for chronic patients with mental illness

BACKGROUND

The aim of this study was to evaluate the effect of an Assertive Community Treatment (ACT) program on psychiatric symptoms, global functioning, life satisfaction, and recovery-promoting relationships among individuals with mental illness.

METHODS

Participants were patients at the Suwon Mental Health Center. Thirty-two patients were part of the ACT program and 32 patients matched for age, sex, and mental illness were in a standard case-management program and served as a control group. Follow-up with patients occurred every 3 months during the 15 months after a baseline interview. Participants completed the Brief Psychiatric Rating Scale (BPRS), Global Assessment of Functioning (GAF) Scale, Life Satisfaction Scale, and Recovery-Promoting Relationship Scale (RPRS).

RESULTS

No significant differences were noted in the sociodemographic characteristics of the ACT and the case-management group. According to the BPRS, the ACT group showed a significant reduction in symptom severity, but the ACT program was not significantly more effective at reducing psychiatric symptoms from baseline to the 15-month follow-up compared to the case-management approach. The ACT group showed more significant improvement than the control group in terms of the GAF Scale. Both groups showed no significant differences in the change of life satisfaction and in the change of recovery-promoting relationships. We observed a significant increase in recovery-promoting relationships in the control group, but the degree of change of recovery-promoting relationships through time flow between groups was not significantly different.

DISCUSSION

In this study, we observed that ACT was significantly better at improving the GAF than case management and that participation in ACT was associated with a significant decrease in BPRS scores. However, ACT did not demonstrate an absolute superiority over the standard case-management approach in terms of the BPRS and the measures of life satisfaction and recovery-promoting relationships.

CONCLUSIONS

ACT may have some advantages over a standard case management approach.

[Hometreatment- an effective alternative to inpatient treatment in child and adolescent psychiatry?]

In many countries hometreatment (HT) offers a cost-effective alternative to hospitalization for children and adolescents with mental health problems requiring intensive mental healthcare. However, the database on HT varies as HT may refer to different models and settings of intensive outpatient treatment. In Germany HT is not used routinely in mental healthcare in child and adolescent psychiatry, therefore the data on HT in Germany, especially in child and adolescent psychiatry, are scarce although funding for studies investigating the effectiveness of HT is available. This review represents a comprehensive search in electronic databases (1980-2014) of literature on HT. It provides as well an overview of the underlying concepts of and the present evidence for HT. In addition, the evidence base on HT for specific child and adolescent mental health disorders is reviewed. Future prospects for the development of HT in Germany facing the upcoming change in health service commissioning (PEPP = «pauschalierendes Entgeltsystem in Psychiatric und Psychosomatik>>) are discussed, as HT in child and adolescent psychiatry, when accurately indicated, can be a valid alternative to inpatient treatment.

Clinical and Functional Outcome of Assertive Outreach for Patients With Schizophrenic Disorder: Results of a Quasi-Experimental Controlled Trial

Background

The majority of studies support modern assertive health service models. However, the evidence is limited for parts of continental Europe, as well as for the pharmacological adherence outcome parameter.

Method

We conducted a quasi-experimental controlled trial including adult patients with a schizophreniform disorder and a maximum of 60 points on the Global Assessment of Functioning Scale (GAF). Interventions (n = 176) and controls (TAU, n = 142) were assessed every six-month within one year in 17 study practices in rural areas. Mental and functional state were rated using the Brief Psychiatric Rating Scale (BPRS) and the GAF. Functional limitations and pharmacological adherence were patient-rated using the WHO-Disability Assessment Schedule II (WHODAS–II) and the Medication Adherence Report Scale (MARS). We computed multilevel mixed models.

Results

The GAF and BPRS of both groups improved significantly, yet the increase in the intervention group was significantly higher. In contrast, patient-rated variables – WHODAS–II and MARS – neither showed a stable temporal improvement nor a difference between groups.

Conclusion

Our findings only partly support the investigated AO intervention, because of conflicting results between clinician- and patient-ratings. Accordingly, the benefits of AO need to be further evaluated.

Decrease in unmet needs contributes to improved motivation for treatment in elderly patients with severe mental illness

PURPOSE

To investigate the pattern of associations between changes in unmet needs and treatment motivation in elderly patients with severe mental illness.

METHODS

Observational longitudinal study in 70 patients treated by an assertive community treatment team for the elderly. Unmet needs and motivation for treatment were measured using the Camberwell assessment of needs for the elderly and the stages-of-change (SoC) scale, respectively, at baseline, after 9 and 18 months. SoC scores were dichotomized into two categories: motivated and unmotivated. Multinomial logistic regression analyses were conducted to determine whether changes in motivation were parallel to or preceded changes in unmet needs.

RESULTS

The number of patients who were not motivated for treatment decreased over time (at baseline 71.4 % was not motivated, at the second measurement 51.4 %, and at 18 months 31.4 % of the patients were not motivated for treatment). A decrease in unmet needs, both from 0-9 to 0-18 months was associated with remaining motivated or a change from unmotivated to becoming motivated during the same observational period (parallel associations). A decrease in unmet needs from 0 to 9 months was also associated with remaining motivated or a change from unmotivated to motivated during the 9-18 months follow-up (sequential associations).

CONCLUSIONS

Our findings suggest that a decrease in unmet needs is associated with improvements in motivation for treatment.

Effects of interferential care: a community-based care program for persons with severe problems on several life areas

BACKGROUND AND AIMS

Interferential care differs from the current community-based care programs in that it targets a larger, heterogeneous group and combines brokerage and full service elements in a multi-organizational care team. The team provides all the services itself, but with the aim to prepare clients within a few months for referral to regular (ambulant) healthcare services. The aim of this study was to assess the effectiveness of interferential care.

METHODS

In a multisite, pretest-posttest design, 523 patients of three interferential care teams were followed. Quality of life, problem severity, problems with referral and engagement were assessed at baseline, at referral and again after 6 months. Analyses were performed using linear mixed modeling.

RESULTS

Interferential care showed moderate to strong effects on quality of life and problem severity. These effects persisted (quality of life) or further improved (problem severity) until follow-up 6 months after referral to regular services. There were also small effects on both engagement and problems with referral.

CONCLUSION

Interferential care offers significant improvements in quality of life and problem severity in persons who have severe problems on several life areas and who are currently not reached by healthcare services. It is a promising community-based care program for healthcare systems in which regular care already contains many elements of home-based practice.

Prevention of involuntary admission through Family Group Conferencing: a qualitative case study in community mental health nursing

AIM

To understand whether and how Family Group Conferencing might contribute to the social embedding of clients with mental illness.

BACKGROUND

Ensuring the social integration of psychiatric clients is a key aspect of community mental health nursing. Family Group Conferencing has potency to create conditions for clients' social embedding and subsequently can prevent coercive measures.

DESIGN

A naturalistic qualitative case study on the process of one conference that was part of 41 conferences that had been organized and studied from January 2011-September 2013 in a public mental health care setting in the north of the Netherlands.

METHODS

Semi-structured interviews (N = 20) were conducted with four stakeholder groups (N = 13) involved in a conference on liveability problems in a local neighbourhood wherein a man with schizophrenia resides.

FINDINGS

To prevent an involuntary admission to a psychiatric ward of a man with schizophrenia, neighbourhood residents requested a family group conference between themselves, the sister of the man and the mental health organization. As a possible conference aggravated psychotic problems, it was decided to organize it without the client. Nine months after the conference, liveability problems in the neighbourhood had been reduced and coercive measures adverted. The conference strengthened the community and resulted in a plan countering liveability problems.

CONCLUSION

The case indicates that social embedding of clients with severe psychiatric problems can be strengthened by Family Group Conferencing and that hence coercive measures can be prevented. A shift is required from working with the individual client to a community driven approach.

The availability and quality across Europe of outpatient care for difficult-to-engage patients with severe mental illness: a survey among experts

BACKGROUND

As many patients with severe mental illness (SMI) who have complex needs are difficult to engage, outreach mental health services are needed to engage them into treatment. The extent to which these services exist in large European cities is unknown.

METHODS

Experts in 29 European countries were sent a structured questionnaire containing two case vignettes of difficult-to-engage patients (a first-episode psychosis patient and a homeless chronic schizophrenia patient). The type and quality of outpatient care was assessed and related to several national indices.

RESULTS

The questionnaire was returned by experts from 22 countries (76%) representing 92% of the EU population. Six countries (21%) had a systematic method for detecting difficult-to-engage patients. The most important route whereby such patients entered the mental health system was through informal care; the most important reasons for entering it were the level of psychiatric symptoms, nuisance and violence. Assertive outreach was available in nine countries (41%), with coverage ranging from a few teams (sometimes for a specific target group) to most of the country. The case vignettes showed that outpatient care for these difficult-to-engage patients varied widely. In seven (30%) of the 22 countries, a hospital would take no action if such patients who had been admitted voluntarily discharged themselves prematurely. On a scale of 0-10, the experts' mean scores regarding the quality of outpatient care for patients with SMI in general were 5.2 (SD = 1.9) and 3.2 (SD = 2.2) in difficult-to-engage ones. Explorative analyses showed that the quality of outpatient care for difficult-to-engage patients was associated with gross national income and the number of psychiatrists per capita.

CONCLUSIONS

Outpatient mental health services for difficult-to-engage SMI patients varied widely among European countries; experts judged their overall quality to be poor. It is now important to achieve consensus on a minimum European standard for the quality of care for such patients.

Can assertive community treatment remedy patients dropping out of treatment due to fragmented services?

Previously, many patients with severe mental illness had difficulties to engage with fragmented mental health services, thus not receiving care. In a Dutch city, Assertive Community Treatment (ACT) was introduced to cater specifically for this group of patients. In a pre-post comparison, changes in mental health care consumption were examined. All mental health care contacts, ACT and non-ACT, of patients in the newly started ACT-teams were extracted from the regional Psychiatric Case Register. Analyses of mental health care usage were performed comparing the period before ACT introduction with the period thereafter. After the introduction of ACT, mental health care use increased in this group of patients, although not all patients remained under the care of ACT teams. ACT may succeed in delivering more mental health care to patients with severe mental illness and treatment needs who previously had difficulties engaging with fragmented mental health care services.

The motivation paradox: higher psychosocial problem levels in severely mentally ill patients are associated with less motivation for treatment

PURPOSE

Lack of motivation for treatment makes a subgroup of patients with severe mental illness (SMI) difficult to engage in psychiatric treatment. Such difficult-to-engage patients may also be the most in need of treatment. We hypothesized that the level of psychosocial problems would be inversely related to motivation for treatment.

METHODS

Cross-sectional study in two independent samples. The first sample (n = 294) included SMI patients who participated in a randomized controlled trial and were assessed using the Health of the Nation Outcome Scales (HoNOS) and self-rated and clinician-rated motivation-for-treatment scales. The second sample (n = 1,170) included SMI patients who were treated in Assertive Outreach Teams and were routinely assessed with the HoNOS and a motivation-for-treatment scale. In both samples, patients also self-rated their quality of life.

RESULTS

In both samples, patients with HoNOS scores of 16 and higher had lower motivation scores on all motivation scales than patients with lower HoNOS scores, and also a lower quality of life.

CONCLUSIONS

A motivation paradox seems inherent to this association between higher psychosocial problems levels, less motivation for treatment, and lower quality of life. Such a paradox has clinical relevance, as it may provide an ethical basis for outreach services which aim to engage marginally motivated SMI patients with severe psychosocial problems into mental health care.

The rise of assertive community interventions in South Africa: a randomized control trial assessing the impact of a modified assertive intervention on readmission rates; a three year follow-up

BACKGROUND

Many countries have over the last few years incorporated mental health assertive interventions in an attempt to address the repercussions of deinstitutionalization. Recent publications have failed to duplicate the positive outcomes reported initially which has cast doubt on the future of these interventions. We previously reported on 29 patients from a developing country who completed 12 months in an assertive intervention which was a modified version of the international assertive community treatment model. We demonstrated reduction in readmission rates as well as improvements in social functioning compared to patients from the control group. The obvious question was, however, if these outcomes could be sustained for longer periods of time. This study aims to determine if modified assertive interventions in an under-resourced setting can successfully maintain reductions in hospitalizations.

METHODS

Patients suffering from schizophrenia who met a modified version of Weidens' high frequency criteria were randomized into two groups. One group received a modified assertive intervention based on the international assertive community treatment model. The other group received standard care according to the model of service delivery in this region. Data was collected after 36 months, comparing readmissions and days spent in hospital.

RESULTS

The results demonstrated significant differences between the groups. Patients in the intervention group had significantly less readmissions (p = 0.007) and spent less days in hospital compared to the patients in the control group (p = 0.013).

CONCLUSION

Modified assertive interventions may be successful in reducing readmissions and days spent in hospital in developing countries where standard care services are less comprehensive. These interventions can be tailored in such a way to meet service needs and still remain affordable and feasible within the context of an under-resourced setting.

The effectiveness of assertive community treatment for elderly patients with severe mental illness: a randomized controlled trial

BACKGROUND

Due to fragmented mental, somatic, and social healthcare services, it can be hard to engage into care older patients with severe mental illness (SMI). In adult mental health care, assertive community treatment (ACT) is an organizational model of care for treating patients with SMI who are difficult to engage. So far all outcome studies of assertive community treatment have been conducted in adults.

METHODS

In a randomized controlled trial design we compared the effectiveness of ACT for elderly patients with that of treatment as usual (TAU). Sixty-two outpatients (60 years and older) with SMI who were difficult to engage in psychiatric treatment were randomly assigned to the intervention or control group (32 to ACT for elderly patients and 30 to TAU). Primary outcomes included number of patients who had a first treatment contact within 3 months, the number of dropouts (i.e. those discharged from care due to refusing care or those who unintentionally lost contact with the service over a period of at least 3 months); and patients' psychosocial functioning (HoNOS65+ scores) during 18 months follow-up. Secondary outcomes included the number of unmet needs and mental health care use. Analyses were based on intention-to-treat.

RESULTS

Of the 62 patients who were randomized, 26 were lost to follow-up (10 patients in ACT for elderly patients and 16 in TAU). Relative to patients with TAU, more patients allocated to ACT had a first contact within three months (96.9 versus 66.7%; X2 (df = 1) = 9.68, p = 0.002). ACT for elderly patients also had fewer dropouts from treatment (18.8% of assertive community treatment for elderly patients versus 50% of TAU patients; X2 (df = 1) = 6.75, p = 0.009). There were no differences in the other primary and secondary outcome variables.

CONCLUSIONS

These findings suggest that ACT for elderly patients with SMI engaged patients in treatment more successfully.

Behandelt zu Hause Gesund werden

Fragestellung: Evaluation zweier Behandlungsformen für psychisch erkrankte Kinder und Jugendliche mit Indikation zur stationären Behandlung: (1) verkürzter stationärer Aufenthalt mit sich anschließender Hometreatmentbehandlung verzahnt mit Klinikelementen aus dem stationären Spektrum (BeZuHG = Behandelt zu Hause gesund werden) (2) stationäre Regelbehandlung (TAU). Methodik: 100 konsekutiv stationär aufgenommene Kinder und Jugendliche wurden in die Studie eingeschlossen und in die Interventionsgruppe (BeZuHG) oder die Kontrollgruppe (stationäre Behandlung) randomisiert. Soziodemographische Daten, ICD-10 und DSM-IV Diagnose, Fragebögen zum psychosozialen Funktionsniveau, Schwere der Symptomatik und Ausmaß der Beeinträchtigung vor und nach der Behandlung wurden erhoben und in Bezug auf Machbarkeit, Outcome, Kontaktfrequenz und Akzeptanz der Familien für beide Behandlungsformen evaluiert. Ergebnisse: Patienten der BeZuHG-Behandlung zeigten gleich gute Behandlungs-Ergebnisse wie stationär behandelte Patienten bei gleichzeitig signifikanter Reduktion der stationären Verweildauer in der BeZuHG-Gruppe. Eine Akzeptanz des BeZuHG-Settings war von den Familien gegeben, eine bessere Einbindung der Eltern in die Behandlung war möglich. Schlussfolgerungen: Sektorenübergreifende Konzepte sollten regelhaft in das Spektrum kinder- und jugendpsychiatrischer Behandlungen integriert werden. Weitere Evaluation ist erforderlich, die Stabilität des Behandlungsergebnisses muss in einem 1-Jahres-Follow-up überprüft werden.

Flexible Assertive Community Treatment, Severity of Symptoms and Psychiatric Health Service Use, a Real life Observational Study

Background:

Introduction of Flexible Assertive Community Treatment (FACT) may be associated with increased remission rates and changes in patterns of care. The present paper reports on differences in psychosocial functioning and health care use between patients in FACT and two groups of patients not currently provided with a specific model of community service.

Methods:

The ongoing "Pharmacotherapy Monitoring and Outcome Survey" provided routine outcome measures of patients using antipsychotics in the north of the Netherlands. Level of psychosocial functioning was assessed using the Health of the Nations Outcome Scales (HoNOS) and matched with psychiatric health care consumption obtained from the Psychiatric Case Register. Patients who never received FACT, patients ever in FACT but not at assessment date, and patients in FACT were identified. Data were subjected to multilevel linear regression analysis.

Results:

Data showed that most patients in FACT also had non-FACT episodes after the start of FACT. Furthermore, patients in FACT displayed higher levels of psychosocial functioning and used more outpatient care than the other two groups.

Conclusions:

Patients in FACT receive more outpatient care and have better psychosocial functioning. However, causal inferences cannot be derived from these data. In addition, membership of a FACT-team in this setting did not last indefinitely.

Efficacy of community treatments for schizophrenia and other psychotic disorders: a literature review

BACKGROUND

In Chile, the clinical guidelines "for the treatment of people from first episode of schizophrenia" aim to support individuals with schizophrenia to live independently, establishment occupational goals, and gain an adequate quality of life and social interaction. This requires the implementation of a treatment model that integrates psychosocial and pharmacological dimensions. Community intervention strategies ensure the achievement of these goals.

OBJECTIVES

This study compiles and synthesizes available scientific evidence from the last 14 years on the effectiveness of community intervention strategies for schizophrenia and related psychotic disorders.

METHODOLOGY

An electronic search was carried out using PUBMED, LILACS, and Science Direct as databases. Criteria of inclusion: (i) randomized clinical trials, (ii) Community-based interventions, (iii) diagnosis of schizophrenia or related psychotic disorder (section F2 of ICD-10).

EXCLUSION CRITERIA

(i) treatments exclusively pharmacological, (ii) interventions carried out in inpatient settings, (iii) bipolar affective disorder or substance-induced psychosis (greater than 50% of sample).

RESULTS

Sixty-six articles were reviewed. Community strategies for integrated treatment from the first outbreak of schizophrenia significantly reduced negative and psychotic symptoms, days of hospitalization, and comorbidity with substance abuse and improved global functioning and adherence to treatment. In other stages, there were improved outcomes in negative and positive symptoms and general psychopathology. Psychoeducation for patients and families reduced the levels of self-stigma and domestic abuse, as well as improved knowledge of the disease and treatment adherence. Training focused on cognitive, social, and labor skills has been shown to improve yields in social functioning and employment status.

CONCLUSION

Community-based intervention strategies are widely supported in the treatment of patients with schizophrenia.

Integrated care in patients with schizophrenia: results of trials published between 2011 and 2013 focusing on effectiveness and efficiency

PURPOSE OF REVIEW

Overview on integrated care trials focusing on effectiveness and efficiency published from 2011 to 2013.

RECENT FINDINGS

Eight randomized controlled trials (RCTs) and 21 non-RCT studies were published from 2011 to 2013. Studies differed in several methodological aspects such as study population, psychotherapeutic approaches used, outcome parameters, follow-up times, fidelities, and implementation of the integrated care model and the nation-specific healthcare context with different control conditions. This makes it difficult to draw firm conclusions. Most studies demonstrated relevant improvements regarding symptoms (P=0.001) and functioning (P=0.01), quality of life (P=0.01), adherence (P<.05) and patient's satisfaction (P=0.01), and reduction of caregiver's stress (P<0.05). Mean total costs were favoring or at least equalizing costs but with positive effects found on subjective health favoring integrated care models.

SUMMARY

There is an increasing interest in the effectiveness and efficiency of integrated care models in patients with mental disorders, specifically in those with severe and persistent mental illness. To increase generalizability, future trials should exactly describe rationales and content of integrated care model and control conditions.

Consumer-providers of care for adult clients of statutory mental health services

BACKGROUND

In mental health services, the past several decades has seen a slow but steady trend towards employment of past or present consumers of the service to work alongside mental health professionals in providing services. However the effects of this employment on clients (service recipients) and services has remained unclear.We conducted a systematic review of randomised trials assessing the effects of employing consumers of mental health services as providers of statutory mental health services to clients. In this review this role is called 'consumer-provider' and the term 'statutory mental health services' refers to public services, those required by statute or law, or public services involving statutory duties. The consumer-provider's role can encompass peer support, coaching, advocacy, case management or outreach, crisis worker or assertive community treatment worker, or providing social support programmes.

OBJECTIVES

To assess the effects of employing current or past adult consumers of mental health services as providers of statutory mental health services.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2012, Issue 3), MEDLINE (OvidSP) (1950 to March 2012), EMBASE (OvidSP) (1988 to March 2012), PsycINFO (OvidSP) (1806 to March 2012), CINAHL (EBSCOhost) (1981 to March 2009), Current Contents (OvidSP) (1993 to March 2012), and reference lists of relevant articles.

SELECTION CRITERIA

Randomised controlled trials of current or past consumers of mental health services employed as providers ('consumer-providers') in statutory mental health services, comparing either: 1) consumers versus professionals employed to do the same role within a mental health service, or 2) mental health services with and without consumer-providers as an adjunct to the service.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies and extracted data. We contacted trialists for additional information. We conducted analyses using a random-effects model, pooling studies that measured the same outcome to provide a summary estimate of the effect across studies. We describe findings for each outcome in the text of the review with considerations of the potential impact of bias and the clinical importance of results, with input from a clinical expert.

MAIN RESULTS

We included 11 randomised controlled trials involving 2796 people. The quality of these studies was moderate to low, with most of the studies at unclear risk of bias in terms of random sequence generation and allocation concealment, and high risk of bias for blinded outcome assessment and selective outcome reporting.Five trials involving 581 people compared consumer-providers to professionals in similar roles within mental health services (case management roles (4 trials), facilitating group therapy (1 trial)). There were no significant differences in client quality of life (mean difference (MD) -0.30, 95% confidence interval (CI) -0.80 to 0.20); depression (data not pooled), general mental health symptoms (standardised mean difference (SMD) -0.24, 95% CI -0.52 to 0.05); client satisfaction with treatment (SMD -0.22, 95% CI -0.69 to 0.25), client or professional ratings of client-manager relationship; use of mental health services, hospital admissions and length of stay; or attrition (risk ratio 0.80, 95% CI 0.58 to 1.09) between mental health teams involving consumer-providers or professional staff in similar roles.There was a small reduction in crisis and emergency service use for clients receiving care involving consumer-providers (SMD -0.34 (95%CI -0.60 to -0.07). Past or present consumers who provided mental health services did so differently than professionals; they spent more time face-to-face with clients, and less time in the office, on the telephone, with clients' friends and family, or at provider agencies.Six trials involving 2215 people compared mental health services with or without the addition of consumer-providers. There were no significant differences in psychosocial outcomes (quality of life, empowerment, function, social relations), client satisfaction with service provision (SMD 0.76, 95% CI -0.59 to 2.10) and with staff (SMD 0.18, 95% CI -0.43 to 0.79), attendance rates (SMD 0.52 (95% CI -0.07 to 1.11), hospital admissions and length of stay, or attrition (risk ratio 1.29, 95% CI 0.72 to 2.31) between groups with consumer-providers as an adjunct to professional-led care and those receiving usual care from health professionals alone. One study found a small difference favouring the intervention group for both client and staff ratings of clients' needs having been met, although detection bias may have affected the latter. None of the six studies in this comparison reported client mental health outcomes.No studies in either comparison group reported data on adverse outcomes for clients, or the financial costs of service provision.

AUTHORS' CONCLUSIONS

Involving consumer-providers in mental health teams results in psychosocial, mental health symptom and service use outcomes for clients that were no better or worse than those achieved by professionals employed in similar roles, particularly for case management services.There is low quality evidence that involving consumer-providers in mental health teams results in a small reduction in clients' use of crisis or emergency services. The nature of the consumer-providers' involvement differs compared to professionals, as do the resources required to support their involvement. The overall quality of the evidence is moderate to low. There is no evidence of harm associated with involving consumer-providers in mental health teams.Future randomised controlled trials of consumer-providers in mental health services should minimise bias through the use of adequate randomisation and concealment of allocation, blinding of outcome assessment where possible, the comprehensive reporting of outcome data, and the avoidance of contamination between treatment groups. Researchers should adhere to SPIRIT and CONSORT reporting standards for clinical trials.Future trials should further evaluate standardised measures of clients' mental health, adverse outcomes for clients, the potential benefits and harms to the consumer-providers themselves (including need to return to treatment), and the financial costs of the intervention. They should utilise consistent, validated measurement tools and include a clear description of the consumer-provider role (eg specific tasks, responsibilities and expected deliverables of the role) and relevant training for the role so that it can be readily implemented. The weight of evidence being strongly based in the United States, future research should be located in diverse settings including in low- and middle-income countries.

Effectiveness of Assertive Community Management in Singapore

Introduction: Assertive Community Treatment (ACT) was introduced in the 1970s as a comprehensive and assertive approach to community-based case management of patients with chronic and serious mental illness. Launched in Singapore in 2003, the Assertive Community Management (ACM) was modelled after the ACT, but with the main difference of 24 hour availability for the latter only. In line with the move towards de-institutionalisation of psychiatric patients, ACM was introduced to provide a mobile community-based multidisciplinary team approach to manage patients with severe chronic psychiatric illness. This article aims to evaluate and provide an update on this service programme in Singapore following an earlier study by Fam Johnson in 2007. Materials and Methods: A naturalistic and retrospective study was conducted. One hundred and fifty-five patients recruited into ACM from 1 September 2008 to 1 September 2009 and had completed 1 year of ACM were included in our study. Outcomes were defined as number of admissions (NOA) and length of stay (LOS) one year before and one year following induction into the programme. Baseline socio-demographic factors were also investigated to see if they predicted outcome with ACM. Results: The mean NOA was 1.9 pre-ACM and 0.6 post-ACM, with mean reduction in NOA of 1.3 (P <0.01). The mean LOS was 72.2 days pre-ACM and 17.1 days post ACM, mean reduction in LOS 55.1 days (P <0.01). In addition, it was found that gender, diagnoses and ethnicity were not predictive of the outcome measures of NOA or LOS.

Effectiveness and efficiency of assertive outreach for Schizophrenia in Germany: study protocol on a pragmatic quasi-experimental controlled trial

BACKGROUND

A model of assertive outreach (AO) in which office-based psychiatrists collaborate with ambulatory nursing services for providing intensive home-treatment is currently being implemented in rural areas of Lower Saxony, Germany. The costs of the model are reimbursed by some of the statutory health insurance companies active in Lower Saxony. Effectiveness and efficiency of this model for patients suffering from schizophrenia is evaluated in a pragmatic and prospective trial.

METHODS

Quasi-experimental controlled trial: patients receiving the intervention are all those receiving AO; controls are patients not eligible for AO based on their health insurance affiliation.

ELIGIBILITY CRITERIA

clinical diagnosis of schizophrenia (ICD-10 F.20), aged at least 18 years and being moderately to severely impaired in global functioning.

PRIMARY OUTCOME

admission and days spent in psychiatric inpatient care; secondary outcomes: clinical and functional status; patient satisfaction with chronic care; health care costs. Follow-up time: 6 and 12 months.

DISCUSSION

The study faces many challenges typical to pragmatic trials such as the rejection of randomisation by service providers, the quality of treatment as usual (TAU) to which the intervention will be compared, and the impairment of the study subjects. Solutions of how to deal with these challenges are presented and discussed in detail.

Current approaches to treatments for schizophrenia spectrum disorders, part II: psychosocial interventions and patient-focused perspectives in psychiatric care

Schizophrenia is a disabling psychiatric illness associated with disruptions in cognition, emotion, and psychosocial and occupational functioning. Increasing evidence shows that psychosocial interventions for people with schizophrenia, as an adjunct to medications or usual psychiatric care, can reduce psychotic symptoms and relapse and improve patients' long-term outcomes such as recovery, remission, and illness progression. This critical review of the literature was conducted to identify the common approaches to psychosocial interventions for people with schizophrenia. Treatment planning and outcomes were also explored and discussed to better understand the effects of these interventions in terms of person-focused perspectives such as their perceived quality of life and satisfaction and their acceptability and adherence to treatments or services received. We searched major health care databases such as EMBASE, MEDLINE, and PsycLIT and identified relevant literature in English from these databases. Their reference lists were screened, and studies were selected if they met the criteria of using a randomized controlled trial or systematic review design, giving a clear description of the interventions used, and having a study sample of people primarily diagnosed with schizophrenia. Five main approaches to psychosocial intervention had been used for the treatment of schizophrenia: cognitive therapy (cognitive behavioral and cognitive remediation therapy), psychoeducation, family intervention, social skills training, and assertive community treatment. Most of these five approaches applied to people with schizophrenia have demonstrated satisfactory levels of short- to medium-term clinical efficacy in terms of symptom control or reduction, level of functioning, and/or relapse rate. However, the comparative effects between these five approaches have not been well studied; thus, we are not able to clearly understand the superiority of any of these interventions. With the exception of patient relapse, the longer-term (eg, >2 years) effects of these approaches on most psychosocial outcomes are not well-established among these patients. Despite the fact that patients' perspectives on treatment and care have been increasingly concerned, not many studies have evaluated the effect of interventions on this perspective, and where they did, the findings were inconclusive. To conclude, current approaches to psychosocial interventions for schizophrenia have their strengths and weaknesses, particularly indicating limited evidence on long-term effects. To improve the longer-term outcomes of people with schizophrenia, future treatment strategies should focus on risk identification, early intervention, person-focused therapy, partnership with family caregivers, and the integration of evidence-based psychosocial interventions into existing services.

[Team-based community psychiatry: importance of context factors and transferability of evidence from studies]

The German Society for Psychiatry, Psychotherapy and Neurology (DGPPN) guidelines on psychosocial interventions for people with severe mental illness appraise the transferability of results of trials evaluating community-based mental health services to the German situation. This assessment has to draw on research results on factors determining effectiveness. This must be seen against the background of a lack of high-quality trials in Germany. The article discusses system, context and setting factors related to the transfer of evidence on community-based service models from other countries. These issues are discussed on the basis of evidence concerning the models of case management, assertive community treatment and community mental health teams. International differences in study findings are highlighted and the importance of treatment-as-usual in influencing study results is emphasized. The more control services including elements of community-based care there are and the less the pressure to reduce inpatient treatment (threshold to inpatient care admission), the smaller the relative effect sizes of innovative care models will be.In the absence of direct evidence, careful examination of transferability is required before introducing health care models. Research has revealed solid evidence for several factors influencing the effects of innovative community mental health care. Among key factors in the care of people with severe mental illness, home visits and joint team responsibility for both psychiatric and social care were identified. This evidence can facilitate the adaptation of successful mental health care models in Germany.

The use of a Cumulative Needs for Care Monitor for individual treatment v. care as usual for patients diagnosed with severe mental illness, a cost-effectiveness analysis from the health care perspective

AIMS

To study the systematic assessment of need for care and clinical parameters for use in treatment plans in patients diagnosed with severe mental illness.

METHODS

The Cumulative Needs for Care Monitor (CNCM) includes various validated instruments, such as the Camberwell Assessment of Need. A Markov-type cost-effectiveness model (health care perspective, 5-year time horizon) was used to compare CNCM with care as usual (CAU). Two studies were used to determine model parameters: a before–after study (n = 2155) and a matched-control study (n = 937).

RESULTS

The CNCM may lead to a gain in psychiatric functioning according to the models. CNCM patients remain in (outpatient) care, while CAU patients drop out more frequently. There is only a small difference in inpatient care. As a result, average costs per patient in the CNCM group are between €2809 (before–after model) and €5251 (matched-control model) higher. The iCER was between €45 127 and €57 839 per life year without psychiatric dysfunction gained.

CONCLUSIONS

CNCM may be only cost-effective when willingness to pay for a life year without psychiatric dysfunction is higher than €45 000. However, this result is highly sensitive to the level of psychiatric dysfunctioning in patients who do not receive care.

Collaboration between local health and local government agencies for health improvement

BACKGROUND

In many countries, national, regional and local inter- and intra-agency collaborations have been introduced to improve health outcomes. Evidence is needed on the effectiveness of locally developed partnerships which target changes in health outcomes and behaviours.

OBJECTIVES

To evaluate the effects of interagency collaboration between local health and local government agencies on health outcomes in any population or age group.

SEARCH METHODS

We searched the Cochrane Public Health Group Specialised Register, AMED, ASSIA, CENTRAL, CINAHL, DoPHER, EMBASE, ERIC, HMIC, IBSS, MEDLINE, MEDLINE In-Process, OpenGrey, PsycINFO, Rehabdata, Social Care Online, Social Services Abstracts, Sociological Abstracts, TRoPHI and Web of Science from 1966 through to January 2012. 'Snowballing' methods were used, including expert contact, citation tracking, website searching and reference list follow-up.

SELECTION CRITERIA

Randomized controlled trials (RCTs), controlled clinical trials (CCTs), controlled before-and-after studies (CBAs) and interrupted time series (ITS) where the study reported individual health outcomes arising from interagency collaboration between health and local government agencies compared to standard care. Studies were selected independently in duplicate, with no restriction on population subgroup or disease.

DATA COLLECTION AND ANALYSIS

Two authors independently conducted data extraction and assessed risk of bias for each study.

MAIN RESULTS

Sixteen studies were identified (28,212 participants). Only two were considered to be at low risk of bias. Eleven studies contributed data to the meta-analyses but a narrative synthesis was undertaken for all 16 studies. Six studies examined mental health initiatives, of which one showed health benefit, four showed modest improvement in one or more of the outcomes measured but no clear overall health gain, and one showed no evidence of health gain. Four studies considered lifestyle improvements, of which one showed some limited short-term improvements, two failed to show health gains for the intervention population, and one showed more unhealthy lifestyle behaviours persisting in the intervention population. Three studies considered chronic disease management and all failed to demonstrate health gains. Three studies considered environmental improvements and adjustments, of which two showed some health improvements and one did not.Meta-analysis of three studies exploring the effect of collaboration on mortality showed no effect (pooled relative risk of 1.04 in favour of control, 95% CI 0.92 to 1.17). Analysis of five studies (with high heterogeneity) looking at the effect of collaboration on mental health resulted in a standardised mean difference of -0.28, a small effect favouring the intervention (95% CI -0.51 to -0.06). From two studies, there was a statistically significant but clinically modest improvement in the global assessment of function symptoms score scale, with a pooled mean difference (on a scale of 1 to 100) of -2.63 favouring the intervention (95% CI -5.16 to -0.10).For physical health (6 studies) and quality of life (4 studies) the results were not statistically significant, the standardised mean differences were -0.01 (95% CI -0.10 to 0.07) and -0.08 (95% CI -0.44 to 0.27), respectively.

AUTHORS' CONCLUSIONS

Collaboration between local health and local government is commonly considered best practice. However, the review did not identify any reliable evidence that interagency collaboration, compared to standard services, necessarily leads to health improvement. A few studies identified component benefits but these were not reflected in overall outcome scores and could have resulted from the use of significant additional resources. Although agencies appear enthusiastic about collaboration, difficulties in the primary studies and incomplete implementation of initiatives have prevented the development of a strong evidence base. If these weaknesses are addressed in future studies (for example by providing greater detail on the implementation of programmes; using more robust designs, integrated process evaluations to show how well the partners of the collaboration worked together, and measurement of health outcomes) it could provide a better understanding of what might work and why. It is possible that local collaborative partnerships delivering environmental Interventions may result in health gain but the evidence base for this is very limited.Evaluations of interagency collaborative arrangements face many challenges. The results demonstrate that collaborative community partnerships can be established to deliver interventions but it is important to agree goals, methods of working, monitoring and evaluation before implementation to protect programme fidelity and increase the potential for effectiveness.

Implementation of assertive community treatment in Australia: model fidelity, patient characteristics and staff experiences

The impact of variable implementation of the Assertive Community Treatment (ACT) model on patient outcomes is increasingly recognised. We conducted the first study of four established Australian ACT teams, examining team composition, processes and model fidelity, using previously validated questionnaires. Demographic and clinical details of patients and their own experiences of ACT were gathered from staff. Associations between burnout and work experiences were examined. All teams were ACT-like (mean DACTS score = 3.7, SD = 0.3) with few significant patient differences between teams, except diagnosis (schizophrenia 61-93%, co-morbid substance abuse 16-33%) and proportion living alone (23-72%). Clinicians were fairly satisfied, but inter-team differences in staffing profile and experience emerged and one team scored highly on emotional exhaustion. Increased burnout was associated with greater stress due to taking a team approach. Inter-team differences suggested that attention to effective team working and leadership, as well as model fidelity, may be warranted.

Effects of an assertive community program in patients with severe mental disorders and impact on their families

AIMS

Assertive community treatment (ACT) is known to have a positive impact on the number and length of inpatient stays. However, recent studies have shown little or no effect of such programs in European settings. This paper aims to describe the impact of a newly implemented ACT program on patients and their families' burden. Predictive factors have also been examined.

METHOD

Fifty-five patients characterized by heavy use of psychiatric care, numerous hospitalizations, or failure to link with outpatient psychiatric care and their relatives were followed. Data were gathered on patients before and after follow up as well as on relatives' burden and costs. The number and domains of clinician interventions have been detailed.

RESULTS

The ACT program had a positive effect on symptoms, psychosocial adaptation and quality of life. Age was the most significant predictor of changes. Older patients, most of them suffering from delusional disorders, showed no improvement or even some impairment. Finally, the program appeared to have a marked effect on easing families' burden in domains such as assistance in daily life activities and costs.

CONCLUSIONS

ACT appears to be recommended for patients with poor outcome when treated in other settings. Early intervention seems to be justified as highlighted by younger age being the best predictor of positive changes. Families can be helped considerably, particularly those confronted with patients with persistent disturbing symptoms which do not, however, warrant hospitalization. Finally, the fact that patients with delusional disorder do not seem to improve warrants further research.

Duration of assertive community treatment and the interpretation of routine outcome data

OBJECTIVE

Statistical inferences based on routine outcome monitoring data are susceptible to biases. Because this process may be influenced by differences in attrition and treatment duration, we wished to gain an insight into the relationship between treatment duration and clinical outcome.

METHOD

We enrolled 569 assertive community treatment (ACT) team patients. As part of a six-monthly routine outcome monitoring (ROM) procedure, we used the Global Assessment of Functioning (GAF) scale, the Health of the Nation Outcome Scales (HoNOS), and a scale to assess their treatment motivation and satisfaction with services. Duration of ACT showed that treatment duration was short for 292 patients [≤ three ROM assessments; 11.6 months (SD = 6.1)], medium for 191 [four to six ROM assessments; 26.9 months (SD = 7.3)], and long for 86 [≥ seven ROM assessments; 44.06 months (SD=7.1)]. Chi-square and ANOVA were used to compare patient characteristics and baseline values across different treatment duration groups, and structural equation modelling was used to unravel interdependencies between the baseline and outcome variables.

RESULTS

More patients receiving long-term ACT were diagnosed with a psychotic disorder and/or substance abuse than those whose treatment was shorter. Patients whose treatment lasted longer had worse baseline GAF and HoNOS scores than those whose treatment was shorter. Structural equation modelling showed that the interdependencies between determinants and outcome variables (concerning the relationships between both identical and non-identical variables over time) were different for each of the treatment duration categories.

CONCLUSIONS

Patients in ACT teams with different treatment durations constitute distinguishable groups with different outcomes. This should be taken into account when using outcome data for benchmarking purposes.
