Plain English Summary

Background and study aims
Crisis Resolution Teams (CRTs) have been set up across England in the last decade to provide rapid assessment and intensive home treatment for people experiencing mental health crises, and prevent hospital admission when possible. Research suggests CRTs reduce hospital admissions and healthcare costs and increase service users' satisfaction with acute care. However, their impact appears to vary between areas and service users and carers report some areas of dissatisfaction with CRT care. There is still uncertainty about how CRTs should be organised and what the critical ingredients of care are. The aim of this study is to evaluate the impact of a CRT resource kit upon service user satisfaction with CRT care. Resource kits consist of guidance, training materials, and coaching and support for service managers and staff. We think that using the resource kit will decrease hospital admissions and improve staff morale.

Who can participate?
Crisis Resolution Teams (CRTs) in the UK

What does the study involve?
Participating CRTs are randomly allocated to either receive a CRT resource kit over a one-year period, or to not receive a CRT resource kit. Service user satisfaction, hospital admission rates and staff morale are compared between the two groups.

What are the possible benefits and risks of participating?

Scientific title

Optimising team functioning, preventing relapse and enhancing recovery in Crisis Resolution Teams (CRTs): the CORE Programme (Crisis team Optimisation and RElapse prevention) CORE Phase 4: A Cluster Randomised Controlled Trial: Evaluation of implementation of a CRT Resource Kit


CORE: Phase 4

Study hypothesis

Aim: The primary aim is to evaluate the impact of a CRT resource kit upon service user satisfaction with CRT care.

Hypothesis: We hypothesise that the implementation of the CRT resource kit will result in an increase in a CRTs fidelity score. Following on from this, we predict that service user satisfaction and perceived continuity of care will be greater in CRTs that receive the resource kit compared to those that do not. In terms of service measures, we hypothesise that teams randomised to receive the resource kit, when compared to those that do not receive the intervention, will have fewer hospital admissions, compulsory admissions and inpatient bed days (adjusting for population size of the catchment area). We also predict that staff morale, wellbeing and job involvement will be greater in teams that receive the resource kit.

Topic: Mental Health; Subtopic: Psychosis; Disease: Psychosis


This is a multi-site, cluster-randomised controlled trial (with CRT service as the unit of randomisation) comparing outcomes for 15 CRTs that receive a CRT resource kit over a one-year study period, with 10 CRTs that do not.

CORE CRT Resource Kit: The CRT resource kit is a team-level intervention, designed to provide guidance and coaching to help CRT managers and staff implement sustainable changes to service organisation and practice. It will be delivered and supported by a resource kit facilitator in each service.

Follow-Up Length: 12 month(s); Study Entry: Registration and One or More Randomisations

Participant type


Age group




Target number of participants

Planned Sample Size: 1265; UK Sample Size: 1265

Participant exclusion criteria

Service user exclusion criteria:
1. People who lack capacity to consent to take part in the study
2. People who in the view of the clinical team at their Crisis Resolution Team present such a high risk of harm to others, it would be unsafe for researchers to contact them about participation, even just by phone or email.
3. People who are discharged to addresses outside the catchment area.
4. People who cannot understand the study information sheet or questionnaire when delivered in English.

CRT exclusion criteria:
1. CRT teams identified in a previous national survey conducted at an earlier stage of the CORE study as already operating at high fidelity (mean item score above 4) - i.e. teams with comparatively little capacity for service improvement
2. CRT teams where major change to the organisation of the service is planned during the duration of the trial
3. CRTs taking part in the concurrent CORE Phase 3 trial
