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

Teamwork and implementation of innovations in healthcare and human service settings: a systematic review

BACKGROUND

Implementation of new practices in team-based settings requires teams to work together to respond to new demands and changing expectations. However, team constructs and team-based implementation approaches have received little attention in the implementation science literature. This systematic review summarizes empirical research examining associations between teamwork and implementation outcomes when evidence-based practices and other innovations are implemented in healthcare and human service settings.

METHODS

We searched MEDLINE, CINAHL, APA PsycINFO and ERIC for peer-reviewed empirical articles published from January 2000 to March 2022. Additional articles were identified by searches of reference lists and a cited reference search for included articles (completed in February 2023). We selected studies using quantitative, qualitative, or mixed methods to examine associations between team constructs and implementation outcomes in healthcare and human service settings. We used the Mixed Methods Appraisal Tool to assess methodological quality/risk of bias and conducted a narrative synthesis of included studies. GRADE and GRADE-CERQual were used to assess the strength of the body of evidence.

RESULTS

Searches identified 10,489 results. After review, 58 articles representing 55 studies were included. Relevant studies increased over time; 71% of articles were published after 2016. We were unable to generate estimates of effects for any quantitative associations because of very limited overlap in the reported associations between team variables and implementation outcomes. Qualitative findings with high confidence were: 1) Staffing shortages and turnover hinder implementation; 2) Adaptive team functioning (i.e., positive affective states, effective behavior processes, shared cognitive states) facilitates implementation and is associated with better implementation outcomes; Problems in team functioning (i.e., negative affective states, problematic behavioral processes, lack of shared cognitive states) act as barriers to implementation and are associated with poor implementation outcomes; and 3) Open, ongoing, and effective communication within teams facilitates implementation of new practices; poor communication is a barrier.

CONCLUSIONS

Teamwork matters for implementation. However, both team constructs and implementation outcomes were often poorly specified, and there was little overlap of team constructs and implementation outcomes studied in quantitative studies. Greater specificity and rigor are needed to understand how teamwork influences implementation processes and outcomes. We provide recommendations for improving the conceptualization, description, assessment, analysis, and interpretation of research on teams implementing innovations.

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.

Receipt and targeting of evidence-based psychosocial interventions for people living with psychoses: findings from the second Australian national survey of psychosis

AIMS.

Clinical Practice Guidelines (CPGs) recommend evidence-based psychosocial interventions (EBPIs) to improve consumer recovery; however, availability appears limited. We describe receipt of six EBPIs, reported by people with psychoses, and associations with service and consumer characteristics, including indicators of need (eligibility) and benefit (suitability).

METHODS.

Participants in the 2010 Australian national survey of psychosis (n = 1825) were interviewed to assess demographic, functional, mental and physical health characteristics and service use in the previous year. Six EBPIs (Cognitive Behaviour Therapy for psychosis; Family Psycho-Education (FPE); Relapse Prevention Planning (RPP); Skills Training; Supported Employment; and Assertive Community Treatment) were chosen, based on the strength and consistency of CPG recommendations. Associations between receipt of interventions and eligibility and suitability indicators were examined via correlations and χ2. Logistic regression was used to predict receipt of one or more EBPIs and to identify predictors of each individual EBPI.

RESULTS.

Less than one-quarter of the sample reported receipt of an evidence-based level of any intervention: rates ranged from 3.4% (FPE) to 21.1% (RPP). The model predicting receipt of one or more EBPIs was statistically significant (χ2 (20, n = 1746) = 216.12, p < 0.01) and marginally useful. Nine variables contributed uniquely, of which six were service characteristics. The strongest predictors of receipt were being assigned a psychologist as a case manager (p < 0.01, OR(CI) = 2.36(1.50-3.72)) and accessing a non-clinical mental health support service in the past year (p < 0.01, OR(CI) = 2.01(1.60-2.51)).

CONCLUSIONS.

Prior reports of limited receipt of EBPIs are reinforced. There is patchy evidence for targeting of EBPIs to those who might benefit most. Service characteristics contribute more to the prediction of receipt than clinical characteristics. Greater implementation effort and better targeting are required to bridge evidence-practice gaps, including improved evidence-based practice literacy among professionals and needs-based service re-design to improve provision and optimise consumer outcomes.

Stigma and discrimination in individuals with severe and persistent mental illness in an assertive community treatment team: Perceptions of families and healthcare professionals

AIM

To explore family member and staff perceptions of clients' experiences of stigma and discrimination, in those living with severe and persistent mental illness in an Assertive Community Treatment Team.

METHOD

This qualitative study used the Discrimination and Stigma Scale to conduct structured face-to-face and telephone interviews of family members and healthcare professionals, working with the Assertive Outreach Team (AOT) (an Assertive Community Treatment Team) of a northern inner suburban catchment of Sydney, New South Wales, Australia.

RESULTS

Forty-one people participated in the study (23 AOT clinical staff members and 18 family members). Family and clinical staff commonly reported stigma and discrimination amongst their relatives and clients, respectively. Four overarching themes emerged from the data: (1) appearance and behaviour, (2) avoidance and being shunned, (3) key areas of life affected by discrimination and (4) impacts of discrimination and skills to cope with discrimination.

CONCLUSION

Reports of stigma and discrimination were common, yet varied between groups with clinical staff commonly witnessing experiences and impacts of discrimination in everyday life, with families' reports being substantially less. Due to the strong advocacy and support provided by the AOT model, clinical staff often buffered experiences of stigma and discrimination. Further research is needed to explore effective interventions to reduce experiences of discrimination in this population group.

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.

Factor structure of therapist fidelity to individual resiliency training in the Recovery After an Initial Schizophrenia Episode Early Treatment Program

BACKGROUND

Evidence-based approaches and early intervention have improved the long-term prognosis of individuals with schizophrenia. However, little is known about the therapeutic processes involved in individual therapy in first-episode psychosis. A comprehensive psychosocial/psychiatric programme for this population, NAVIGATE, includes an individual therapy component, individual resiliency training (IRT). Fidelity of clinicians' adherence to the IRT protocol has been collected to ensure proper implementation of this manual-based intervention. These data can provide insight into the elements of the therapeutic process in this intervention.

MATERIALS AND METHODS

To achieve this goal, we first examined the factor structure of the IRT fidelity scale with exploratory factor analysis. Second, we explored the relationships among the IRT fidelity ratings with clinician years of experience and years of education, as well as client's baseline symptom severity and duration of untreated psychosis.

RESULTS AND CONCLUSIONS

Results supported a 2-factor structure of the IRT fidelity scale. Correlations between clinician years of education and fidelity ratings were statistically significant.

Building flexibility and managing complexity in community mental health: lessons learned in a large urban centre

BACKGROUND

Across many jurisdictions, adults with complex mental health and social needs face challenges accessing appropriate supports due to system fragmentation and strict eligibility criteria of existing services. To support this underserviced population, Toronto's local health authority launched two novel community mental health models in 2014, inspired by Flexible Assertive Community Team principles. This study explores service user and provider perspectives on the acceptability of these services, and lessons learned during early implementation.

METHODS

We purposively sampled 49 stakeholders (staff, physicians, service users, health systems stakeholders) and conducted 17 semi-structured qualitative interviews and 5 focus groups between October 23, 2014 and March 2, 2015, exploring stakeholder perspectives on the newly launched team based models, as well as activities and strategies employed to support early implementation. Interviews and focus groups were audio recorded, transcribed verbatim and analyzed using thematic analysis.

RESULTS

Findings revealed wide-ranging endorsement for the two team-based models' success in engaging the target population of adults with complex service needs. Implementation strengths included the broad recognition of existing service gaps, the use of interdisciplinary teams and experienced service providers, broad partnerships and collaboration among various service sectors, training and team building activities. Emerging challenges included lack of complementary support services such as suitable housing, organizational contexts reluctant to embrace change and risk associated with complexity, as well as limited service provider and organizational capacity to deliver evidence-based interventions.

CONCLUSIONS

Findings identified implementation drivers at the practitioner, program, and system levels, specific to the implementation of community mental health interventions for adults with complex health and social needs. These can inform future efforts to address the health and support needs of this vulnerable population.

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.

A qualitative exploration of service users' information needs and preferences when receiving a serious mental health diagnosis

Helpful strategies for communicating news of a serious mental health diagnosis are poorly understood. This study explored service users' preferences for how they would like clinicians to deliver such news when a diagnosis of mental illness is made. Qualitative interviews were conducted with forty-five individuals identifying with serious mental illness in eleven community based mental health facilities. Inductive thematic analysis resulted in eight primary themes. Five themes related to the structure and content of the discussion; including a focus on information exchange, using an individualized collaborative partnership paradigm, addressing stigma, balancing hope with realism, and recognizing the dynamic nature of diagnosis. The remaining themes related to the involvement of others; including the importance of clinicians' communication and relationship skills, involvement and education of carers, and offering an opportunity for peer support. The product of the synthesis of themes is a step-wise model for communicating news of mental health diagnosis.

A retrospective quasi-experimental study of a transitional housing program for patients with severe and persistent mental illness

Transitional housing programs aim to improve living skills and housing stability for tenuously housed patients with mental illness. 113 consecutive Transitional Housing Team (THT) patients were matched to 139 controls on diagnosis, time of presentation, gender and prior psychiatric hospitalisation and compared using a difference-in-difference analysis for illness acuity and service use outcomes measured 1 year before and after THT entry/exit. There was a statistically significant difference-in-difference favouring THT participants for bed days (mean difference in difference -20.76 days, SE 9.59, p = 0.031) and living conditions (HoNOS Q11 mean difference in difference -0.93, SE 0.23, p < 0.001). THT cost less per participant (I$14,024) than the bed-days averted (I$17,348). The findings of reductions in bed days and improved living conditions suggest that transitional housing programs can have a significant positive impact for tenuously housed patients with high inpatient service usage, as well as saving costs for mental health services.

A retrospective quasi-experimental study of a community crisis house for patients with severe and persistent mental illness

OBJECTIVE

There is increasing international evidence that crisis houses can reduce the time spent in acute psychiatric inpatient units for patients with severe and persistent mental illness, at a lower cost and in an environment preferable to patients. We evaluated the Alternatives to Hospitalisation (AtH) program, a crisis house operating in outer suburban Brisbane.

METHODS

One hundred and ninety-three AtH patients were compared to 371 matched controls admitted to a peer hospital district acute psychiatric unit. Hospitalisations, demographics and illness acuity were compared one year before and after an acute index episode of residential care involving hospital and/or AtH. Hospital bed-days during the index episode were compared between AtH participants and controls. The cost of bed-days averted was compared to the cost of providing the AtH program.

RESULTS

AtH participants spent 5.35 fewer days in hospital during the index episode than controls, after adjustment for illness acuity, living conditions, marital status and emergency department (ED) presentations. Per patient cost of averted psychiatric inpatient bed-days, $5948.22, was higher than the per patient cost of providing AtH, $3071.44. AtH participants had higher levels of illness acuity, ED presentations and acute psychiatric admissions than controls in the year after the index episode.

CONCLUSIONS

For acutely unwell, stably housed patients, able to be managed outside of a secure facility, a crisis house program can reduce acute psychiatric bed-days, providing a cost saving for mental health services.
