Implementing the protocol of a pilot randomized controlled trial for the recovery-oriented intervention to people with psychoses in two Latin American cities

Critical Time Intervention - Task-Shifting for Individuals with Psychosis in Latin America: A Multi-stakeholder Qualitative Analysis of Implementation Barriers and Facilitators

This article presents the results of a qualitative study conducted to understand the barriers and facilitators in implementing a pilot trial of Critical Time Intervention-Task-Shifting-a time-limited, community-based, recovery-oriented intervention for individuals with psychosis-in Rio de Janeiro, Brazil, and Santiago, Chile. Data included 40 semi-structured interviews with service users, task-shifting providers, and administrators. Analysis proceeded in three iterative phases and combined inductive and deductive approaches. Coding frameworks for implementation factors, and whether or not they acted as barriers and facilitators, were developed and refined using many domains and constructs from the Consolidated Framework for Implementation Research. Barriers and facilitators were ultimately grouped into five domains: 1-Personal; 2-Interpersonal; 3-Intervention; 4-Mental Health System; and 5-Contextual. A rating system was also developed and applied, which enabled comparisons across stakeholders and study sites. Major facilitators included intervention characteristics such as the roles of the task-shifting providers and community-based care. Top barriers included mental health stigma and community conditions (violence). Nevertheless, the findings suggest that Critical Time Intervention-Task-Shifting is largely acceptable and feasible, and could contribute to efforts to strengthen community mental health systems of care for individuals with psychosis in Latin America, especially in advancing the task-shifting strategy and the recovery-oriented approach.

Intersectoral and multisectoral approaches to enable recovery for people with severe mental illness in low- and middle-income countries: A scoping review

The needs of people with severe mental illness are complex and require a range of services embedded in well-coordinated systems of care to enable recovery, promote well-being and optimise social integration. The concept of recovery is strongly rooted in the centrality of multi and intersectoral systems of care, and, while multi and -intersectoral dimensions of mental health systems have been highlighted in analyses focusing on high-income regions, little has been elaborated in terms of these approaches in the recovery of people with severe mental illness (SMI) in low- and middle-income countries (LMICs). The aim of this review was to identify and describe multi and intersectoral approaches underpinning community-based SMI recovery interventions in LMICs. A scoping review was carried out following the following steps: (1) Objectives for the review were developed and refined; (2) A systematic search of databases (EbscoHost, PubMed, Google Scholar) and previous reviews were undertaken from 2012 to 2022, where relevant papers were identified; (3) Papers with a focus on SMI and recovery, a specific description of an intervention, located in LMICs, with explicit linkages between sectors, and published in English, were selected for inclusion; (4) Data were extracted and charted and (5) Findings were analysed and reported thematically. Thirty-six papers were included for analysis, from 18 countries, including qualitative studies, trials, desktop and secondary data reviews and case studies. Examples of multi- and intersectoral action included collaboration between healthcare and community support systems, collaboration in providing supported housing and supportive community spaces for recovery, and linkages between biomedical and social spheres of care. Barriers included the dominance of mental health professions in delivering care, community-based stigmatising attitudes towards SMI. Multi- and intersectoral collaboration for SMI recovery requires investments in financing, education and coordination by a governing body.

A Recovery-Oriented Intervention for People With Psychosis: A Pilot Randomized Controlled Trial

OBJECTIVE

This pilot randomized controlled trial evaluated the effectiveness of critical time intervention-task shifting (CTI-TS) for people with psychosis in Santiago, Chile, and Rio de Janeiro. CTI-TS is a 9-month intervention involving peer support workers and is designed to maintain treatment effects up to 18 months.

METHODS

A total of 110 people with psychosis were recruited when they enrolled in community mental health clinics (Santiago, N=60; Rio de Janeiro, N=50). Participants within each city were randomly assigned to either CTI-TS or usual care for 9 months. Primary outcomes were quality of life, measured with the World Health Organization Quality of Life Assessment-Brief Version (WHOQOL-BREF), and unmet needs, measured with the Camberwell Assessment of Need (CAN), at 18-month follow-up. Results were analyzed according to intention-to-treat guidelines. Generalized estimating equations, with observations clustered within cities, and multiple imputation for missing data were used.

RESULTS

At 18 months, both groups showed improved primary outcomes. In both unadjusted and fully adjusted analyses, no significant differences between CTI-TS and usual care (WHOQOL-BREF question on quality of life and CAN mean number of unmet needs) were found.

CONCLUSIONS

Three factors might explain the lack of difference between CTI-TS and usual care: first-contact enrollment precluded rapport prior to randomization, a minority of patients were uncomfortable with peers being on the treatment team, and primary outcome measures may not have been sensitive enough to capture the effects of a recovery-oriented intervention. The results have implications for the design of transitional services for people with psychosis, especially in Latin America.

Comparing two implementation strategies for implementing and sustaining a case management practice serving homeless-experienced veterans: a protocol for a type 3 hybrid cluster-randomized trial

Background

The Veterans Health Administration (VA) Grant and Per Diem case management “aftercare” program provides 6 months of case management for homeless-experienced veterans (HEVs) undergoing housing transitions. To standardize and improve aftercare services, we will implement critical time intervention (CTI), an evidence-based, structured, and time-limited case management practice. We will use two strategies to support the implementation and sustainment of CTI at 32 aftercare sites, conduct a mixed-methods evaluation of this implementation initiative, and generate a business case analysis and implementation playbook to support the continued spread and sustainment of CTI in aftercare.

Methods

We will use the Replicating Effective Programs (REP) implementation strategy to support CTI implementation at 32 sites selected by our partners. Half (n=16) of these sites will also receive 9 months of external facilitation (EF, enhanced REP). We will conduct a type 3 hybrid cluster-randomized trial to compare the impacts of REP versus enhanced REP. We will cluster potential sites into three implementation cohorts staggered in 9-month intervals. Within each cohort, we will use permuted block randomization to balance key site characteristics among sites receiving REP versus enhanced REP; sites will not be blinded to their assigned strategy. We will use mixed methods to assess the impacts of the implementation strategies. As fidelity to CTI influences its effectiveness, fidelity to CTI is our primary outcome, followed by sustainment, quality metrics, and costs. We hypothesize that enhanced REP will have higher costs than REP alone, but will result in stronger CTI fidelity, sustainment, and quality metrics, leading to a business case for enhanced REP. This work will lead to products that will support our partners in spreading and sustaining CTI in aftercare.

Discussion

Implementing CTI within aftercare holds the potential to enhance HEVs’ housing and health outcomes. Understanding effective strategies to support CTI implementation could assist with a larger CTI roll-out within aftercare and support the implementation of other case management practices within and outside VA.

OnTrack Chile for people with early psychosis: a study protocol for a Hybrid Type 1 trial

BACKGROUND

Substantial data from high-income countries support early interventions in the form of evidence-based Coordinated Specialty Care (CSC) for people experiencing First Episode Psychosis (FEP) to ameliorate symptoms and minimize disability. Chile is unique among Latin American countries in providing universal access to FEP services through a national FEP policy that mandates the identification of FEP individuals in primary care and guarantees delivery of community-based FEP treatments within a public health care system. Nonetheless, previous research has documented that FEP services currently provided at mental health clinics do not provide evidence-based approaches. This proposal aims to address this shortfall by first adapting OnTrackNY (OTNY), a CSC program currently being implemented across the USA, into OnTrackChile (OTCH), and then examine its effectiveness and implementation in Chile.

METHODS

The Dynamic Adaptation Process will be used first to inform the adaptation and implementation of OTCH to the Chilean context. Then, a Hybrid Type 1 trial design will test its effectiveness and cost and evaluate its implementation using a cluster-randomized controlled trial (RCT) (N = 300 from 21 outpatient clinics). The OTCH program will be offered in half of these outpatient clinics to individuals ages 15-35. Usual care services will continue to be offered at the other clinics. Given the current COVID-19 pandemic, most research and intervention procedures will be conducted remotely. The study will engage participants over the course of 2 years, with assessments administered at enrollment, 12 months, and 24 months. Primary outcomes include implementation (fidelity, acceptability, and uptake) and service outcomes (person-centeredness, adherence, and retention). Secondary outcomes comprise participant-level outcomes such as symptoms, functioning, and recovery orientation. Over the course of the study, interviews and focus groups with stakeholders will be conducted to better understand the implementation of OTCH.

DISCUSSION

Findings from this study will help determine the feasibility, effectiveness, and cost for delivering CSC services in Chile. Lessons learned about facilitators and barriers related to the implementation of the model could help inform the approach needed for these services to be further expanded throughout Latin America.

Understanding Users' Perspectives of Psychosocial Mechanisms Underpinning Peer Support Work in Chile

This study explores the beliefs and attitudes about the psychosocial mechanisms of peer support work among users who participated in Critical Time Intervention-Task Shifting (CTI-TS), which tested the acceptability and feasibility of a peer support work model to improve community-based mental health care for individuals with psychosis in Latin America. We conducted a secondary analysis of 15 in-depth interviews with CTI-TS participants in Chile, using the framework method and defined the framework domains based on five major mechanisms of peer support work identified by a recent literature review. The analysis revealed that users' perceptions of peer support work mechanisms were strongly shaped by personal motivations, beliefs about professional hierarchies, familial support, and the Chilean mental health system's incipient recovery orientation. The findings underscore the importance of adopting culturally tailored strategies to promote peer support work, such as involving mental health professionals and fostering equal-powered relationships between PSWs and users.

Utility of a multidimensional recovery framework in understanding lived experiences of Chilean and Brazilian mental health service users

La comprensión y aplicación del concepto de recuperación, a pesar de sus posibles beneficios para los servicios de salud mental, aún se encuentra en incipiente desarrollo en América Latina. Si bien la reforma psiquiátrica en la región ha tenido algunos avances, el marco de la recuperación no ha sido suficientemente explorado. Whitley y Drake (2010) sugirieron un marco conceptual integral para la recuperación que incluye cinco dimensiones: clínica, existencial, funcional, física y social. El presente estudio tuvo como objetivo explorar las perspectivas de los usuarios chilenos y brasileños sobre la recuperación identificando su adscripción y aplicabilidad de estas cinco dimensiones. Se entrevistó a treinta participantes de la Intervención en Momento Crítico-Delegación de Funciones (CTI-TS) realizada en Santiago (Chile) y en Río de Janeiro (Brasil) sobre sus experiencias de recuperación. Se exploró la aplicabilidad del marco de Whitley y Drake al contexto de Chile y de Brasil. Los resultados mostraron que: 1. El marco era aplicable a esta población; 2. Las dimensiones presentaban un tipo particular de entrelazamiento y estaban influenciadas por una serie de procesos tales como la continuidad en el proceso de atención/cuidado/autocuidado, y sobresalía la funcionalidad y la esfera social; 3. Los valores culturales, el estigma y los determinantes sociales emergieron como factores cruciales que afectan el tratamiento y la recuperación. Se propuso una reinterpretación del esquema referencial. Los hallazgos representan un aporte a la literatura internacional sobre recuperación al aumentar la validez de este marco referencial multidimensional y su aplicabilidad a diversas poblaciones.

Implementation of a pilot community-based psychosocial intervention for patients with psychoses in Chile and Brazil: a comparative analysis of users' perspectives

BACKGROUND

Few studies provide clear rationale for and the reception of adaptations of evidence-based interventions. To address this gap, we describe the context-dependent adaptations in critical time intervention-task shifting (CTI-TS), a manualized recovery program for individuals with psychosis in Rio de Janeiro, Brazil and Santiago, Chile. Implications of the adaptations - incorporating a task-shifting approach and modifying the mode of community-based service delivery - are examined from users' perspectives.

METHODS

A secondary analysis of in-depth interviews with CTI-TS users (n = 9 in Brazil; n = 15 in Chile) was conducted. Using the framework method, we thematically compared how participants from each site perceived the main adapted components of CTI-TS.

RESULTS

Users of both sites appreciated the task-shifting worker pair to provide personalized, flexible, and relatable support. They wanted CTI-TS to be longer and experienced difficulty maintaining intervention benefits in the long-term. In Chile, stigma and a perceived professional hierarchy toward the task-shifting providers were more profound than in Brazil. Engagement with community-based services delivery in homes and neighborhoods (Chile), and at community mental health centers (Brazil) were influenced by various personal, familial, financial, and social factors. Uniquely, community violence was a significant barrier to engagement in Brazil.

CONCLUSION

CTI-TS' major adaptations were informed by the distinct mental health systems and social context of Santiago and Rio. Evaluation of user experiences with these adaptations provides insights into implementing and scaling-up task-shifting and community-oriented interventions in the region through the creation of specialized roles for the worker pair, targeting sustained intervention effects, and addressing socio-cultural barriers.

Experts by Experience: Qualitative Evaluation of Adolescent Participation in the Development of a Technological Intervention to Prevent Youth Suicide in Chile

Adolescent suicide is a pressing problem in Chile that has not yet been sufficiently addressed, as suicide rates have stagnated in recent years. One possible explanation could be linked to the adult-centered paradigm that continues to prevail in relation to adolescent health initiatives. In light of this, programs that seek to promote youth mental health should consider incorporating adolescents in the design process using participatory methodologies, to ensure that these initiatives are well-suited for the population. In line with this recommendation, a group of seven adolescents, 13 to 20 years of age, were incorporated into a research team to actively guide the design, development, and validation of a technology-based intervention, known as Project Clan, which was piloted to reduce adolescent suicide in schools in Chile. This group was known as the "Group of Experts," in acknowledgment of their role as experts by experience on adolescence. A qualitative case study was conducted to explore their lived experiences, through semistructured individual in-depth interviews with six members of the group. Results showed that the adolescents had a high level of interest in mental health and had experienced problems of their own or accompanied friends who were struggling, which motivated their participation in the study. They had a critical view of the previous interventions they had received through educational institutions and valued their role in the promotion of their peers' mental health through the Group of Experts. They also highlighted the importance of creating tools that complement their daily lives and provide an alternative to existing social networks, by respecting their anonymity, providing a secure place for divulgation and self-expression, and facilitating access to professional support. We conclude that programs that address issues that affect adolescents should incorporate adolescents in the decision-making and design processes to ensure the acceptability and effectivity of their interventions.
