Crisis resolution/home treatment team workers' understandings of the concept of crisis

Explaining context, mechanism and outcome in adult community mental health crisis care: A realist evidence synthesis

Mental health crises cause significant distress and disruption to the lives of individuals and their families. Community crisis care systems are complex, often hard to navigate and poorly understood. This realist evidence synthesis aimed to explain how, for whom and in what circumstances community mental health crisis services for adults work to resolve crises and is reported according to RAMESES guidelines. Using realist methodology, initial programme theories were identified and then tested through iterative evidence searching across 10 electronic databases, four expert stakeholder consultations and n = 20 individual interviews. 45 relevant records informed the three initial programme theories, and 77 documents, were included in programme theory testing. 39 context, mechanism, outcome configurations were meta-synthesized into three themes: (1) The gateway to urgent support; (2) Values based crisis interventions and (3) Leadership and organizational values. Fragmented cross-agency responses exacerbated staff stress and created barriers to access. Services should focus on evaluating interagency working to improve staff role clarity and ensure boundaries between services are planned for. Organizations experienced as compassionate contributed positively to perceived accessibility but relied on compassionate leadership. Attending to the support needs of staff and the proximity of leaders to the front line of crisis care are key. Designing interventions that are easy to navigate, prioritize shared decision-making and reduce the risk of re-traumatizing people is a priority.

Explanation of context, mechanisms and outcomes in adult community mental health crisis care: the MH-CREST realist evidence synthesis

Background

Mental health crises cause significant disruption to individuals and families and can be life-threatening. The large number of community crisis services operating in an inter-agency landscape complicates access to help. It is unclear which underpinning mechanisms of crisis care work, for whom and in which circumstances.

Aim

The aim was to identify mechanisms to explain how, for whom and in what circumstances adult community crisis services work.

Objectives

The objectives were to develop, test and synthesise programme theories via (1) stakeholder expertise and current evidence; (2) a context, intervention, mechanism and outcome framework; (3) consultation with experts; (4) development of pen portraits; (5) synthesis and refinement of programme theories, including mid-range theory; and (6) identification and dissemination of mechanisms needed to trigger desired context-specific crisis outcomes.

Design

This study is a realist evidence synthesis, comprising (1) identification of initial programme theories; (2) prioritisation, testing and refinement of programme theories; (3) focused realist reviews of prioritised initial programme theories; and (4) synthesis to mid-range theory.

Main outcome

The main outcome was to explain context, mechanisms and outcomes in adult community mental health crisis care.

Data sources

Data were sourced via academic and grey literature searches, expert stakeholder group consultations and 20 individual realist interviews with experts.

Review methods

A realist evidence synthesis with primary data was conducted to test and refine three initial programme theories: (1) urgent and accessible crisis care, (2) compassionate and therapeutic crisis care and (3) inter-agency working.

Results

Community crisis services operate best within an inter-agency system. This requires compassionate leadership and shared values that enable staff to be supported; retain their compassion; and, in turn, facilitate compassionate interventions for people in crisis. The complex interface between agencies is best managed through greater clarity at the boundaries of services, making referral and transition seamless and timely. This would facilitate ease of access and guaranteed responses that are trusted by the communities they serve.

Strengths and limitations

Strengths include the identification of mechanisms for effective inter-agency community crisis care and meaningful stakeholder consultation that grounded the theories in real-life experience. Limitations include the evidence being heavily weighted towards England and the review scope excluding full analysis of ethnic and cultural diversity.

Conclusions

Multiple interpretations of crises and diverse population needs present challenges for improving the complex pathways to help in a crisis. Inter-agency working requires clear policy guidance with local commissioning. Seamless transitions between services generate trust through guaranteed responses and ease of navigation. This is best achieved where there is inter-agency affiliation that supports co-production. Compassionate leaders engender staff trust, and outcomes for people in crisis improve when staff are supported to retain their compassion.

Future work

Further work might explore inter-agency models of crisis delivery, particularly in rural communities. Future work could focus on evaluating outcomes across crisis care provider agencies and include evaluation of individual, as well as service-level, outcomes. The implementation and effect of mental health triage could be explored further, including via telehealth. Barriers to access for marginalised populations warrant a specific focus in future research.

A scoping review of studies into crisis resolution teams in community mental health services

BACKGROUND AND PURPOSE OF ARTICLE

Crisis Resolution Teams (CRT) for rapid assessment and short-term treatment of mental health problems have increasingly been implemented internationally over the last decades. Among the Nordic countries, the CRT model has been particularly influential in Norway, where 'Ambulante akutteam (AAT)' is a widespread psychiatric emergency service for adult patients. However, the clinical practice of these teams varies significantly. To aid further development of the service and guide future research efforts, we carried out a scoping review to provide an up-to-date overview of research available in primary studies focusing on phenomena related to CRTs in English and Scandinavian literature.

METHODS

A systematic literature search was conducted in the bibliometric databases MEDLINE, Embase, PsychINFO, Scopus, and SveMed+. Included studies were thematically analyzed using a qualitative method.

RESULTS

The search identified 1516 unique references, of which 129 were included in the overview. Thematic analysis showed that the studies could be assigned to: (1) Characteristics of CRTs (k = 45), which described key principles or specific interventions; (2) Implementation of CRTs (k = 54), which were descriptive about implementation in different teams, or normative about what clinical practice should include; and (3) Effect of CRTs (k = 38).

CONCLUSIONS

The international research literature on CRTs or equivalent teams is extensive. Many sub-themes have been studied with various research methodologies. Recent studies provide a better evidence base for how to organize services and to select therapeutic interventions, but there is still a need for more controlled studies in the field.

Crisis-focused Cognitive Behavioural Therapy for psychosis (CBTp) in acute mental health inpatient settings (the CRISIS study): protocol for a pilot randomised controlled trial

Background

Cognitive Behavioural Therapy for psychosis (CBTp) has an established evidence base and is recommended by clinical guidelines to be offered during the acute phases of psychosis. However, few research studies have examined the efficacy of CBTp interventions specifically adapted for the acute mental health inpatient context with most research trials being conducted with white European community populations.

Aims

The aim of this study is to conduct a pilot randomised controlled trial (RCT), which incorporates the examination of feasibility markers, of a crisis-focused CBTp intervention adapted for an ethnically diverse acute mental health inpatient population, in preparation for a large-scale randomised controlled trial. The study will examine the feasibility of undertaking the trial, the acceptability and safety of the intervention and the suitability of chosen outcome measures. This will inform the planning of a future, fully powered RCT.

Methods

A single-site, parallel-group, pilot RCT will be conducted examining the intervention. Drawing on principles of coproduction, the intervention has been adapted in partnership with key stakeholders: service users with lived experience of psychosis and of inpatient care (including those from ethnic minority backgrounds), carers, multi-disciplinary inpatient clinicians and researchers. Sixty participants with experience of psychosis and in current receipt of acute mental health inpatient care will be recruited. Participants will be randomly allocated to either the crisis-focused CBTp intervention or treatment as usual (TAU).

Discussion

Findings of this pilot RCT will indicate whether a larger multi-site RCT is needed to investigate the efficacy of the intervention. If the initial results demonstrate that this trial is feasible and the intervention is acceptable, it will provide evidence that a full-scale effectiveness trial may be warranted.

Trial registration

This trial has been prospectively registered on the ISRCTN registry (ISRCTN59055607) on the 18th of February 2021.

Real-World Clinical Outcomes Two Years After Transition to Psychosis in Individuals at Clinical High Risk: Electronic Health Record Cohort Study

The objective of this study is to describe the 2-year real-world clinical outcomes after transition to psychosis in patients at clinical high-risk. The study used the clinical electronic health record cohort study including all patients receiving a first index primary diagnosis of nonorganic International Classification of Diseases (ICD)-10 psychotic disorder within the early psychosis pathway in the South London and Maudsley (SLaM) National Health Service (NHS) Trust from 2001 to 2017. Outcomes encompassed: cumulative probability (at 3, 6, 12, and 24 months) of receiving a first (1) treatment with antipsychotic, (2) informal admission, (3) compulsory admission, and (4) treatment with clozapine and (5) numbers of days spent in hospital (at 12 and 24 months) in patients transitioning to psychosis from clinical high-risk services (Outreach and Support in south London; OASIS) compared to other first-episode groups. Analyses included logistic and 0-inflated negative binomial regressions. In the study, 1561 patients were included; those who had initially been managed by OASIS and had subsequently transitioned to a first episode of psychosis (n = 130) were more likely to receive antipsychotic medication (at 3, 6, and 24 months; all P < .023), to be admitted informally (at all timepoints, all P < .004) and on a compulsory basis (at all timepoints, all P < .013), and to have spent more time in hospital (all timepoints, all P < .007) than first-episode patients who were already psychotic when seen by the OASIS service (n = 310), or presented to early intervention services (n = 1121). The likelihood of receiving clozapine was similar across all groups (at 12/24 months, all P < .101). Transition to psychosis from a clinical high-risk state is associated with severe real-world clinical outcomes. Prevention of transition to psychosis should remain a core target of future research.

Implementation of the Crisis Resolution Team model in adult mental health settings: a systematic review

BACKGROUND

Crisis Resolution Teams (CRTs) aim to offer an alternative to hospital admission during mental health crises, providing rapid assessment, home treatment, and facilitation of early discharge from hospital. CRTs were implemented nationally in England following the NHS Plan of 2000. Single centre studies suggest CRTs can reduce hospital admissions and increase service users' satisfaction: however, there is also evidence that model implementation and outcomes vary considerably. Evidence on crucial characteristics of effective CRTs is needed to allow team functioning to be optimised. This review aims to establish what evidence, if any, is available regarding the characteristics of effective and acceptable CRTs.

METHODS

A systematic review was conducted. MEDLINE, Embase, PsycINFO, CINAHL and Web of Science were searched to November 2013. A further web-based search was conducted for government and expert guidelines on CRTs. We analysed studies separately as: comparing CRTs to Treatment as Usual; comparing two or more CRT models; national or regional surveys of CRT services; qualitative studies of stakeholders' views regarding best practice in CRTs; and guidelines from government and expert organisations regarding CRT service delivery. Quality assessment and narrative synthesis were conducted. Statistical meta-analysis was not feasible due to the variety of design of retrieved studies.

RESULTS

Sixty-nine studies were included. Studies varied in quality and in the composition and activities of the clinical services studied. Quantitative studies suggested that longer opening hours and the presence of a psychiatrist in the team may increase CRTs' ability to prevent hospital admissions. Stakeholders emphasised communication and integration with other local mental health services; provision of treatment at home; and limiting the number of different staff members visiting a service user. Existing guidelines prioritised 24-hour, seven-day-a-week CRT service provision (including psychiatrist and medical prescriber); and high quality of staff training.

CONCLUSIONS

We cannot draw confident conclusions about the critical components of CRTs from available quantitative evidence. Clearer definition of the CRT model is required, informed by stakeholders' views and guidelines. Future studies examining the relationship of overall CRT model fidelity to outcomes, or evaluating the impact of key aspects of the CRT model, are desirable.
