Description of intervention(s) / exposure
The exposure is the utilisation of a CRT service. Since March 2020, the CRT, consisting of a police officer, paramedic and a mental health professional, have been jointly deployed to provide a wrap-around service for mental health 111 calls. The team provides timely ‘on scene’ support to people in mental distress. Objectives of the CRT include enhanced care for people suffering mental distress in the community and a reduced flow into mental health services and emergency departments. We are recruiting approximately 20 people who have been exposed to the CRT ( direct users and their family members) and we will conduct qualitative interviews exploring their experiences. The interviews will be face-to-face (or via zoom or by telephone) and last for about 30 minutes. The CRT service users will be contacted within approximately 2 weeks of their CRT use to invite them to participate in the study.

Primary outcome [1] 324498 0
The composite primary outcome is to explore the views/experiences of people (both CRT users and their family members/whanau) who received input from the CRT. We are interested in how easy it was to access the CRT, what interventions they received and what the outcomes were following the CRT input. We will also inquire about positive and negative aspects that the CRT user/family member experienced and their suggestions for improvement. The views of the CRT users and family members/whanau will be assessed by conducting one-on-one 30-minute semi-structured audio-recorded interviews.
Timepoint [1] 324498 0
CRT users and family/whanau will be contacted within approximately 2 weeks of their contact with the CRT. The interview needs to occur within 6 months of the CRT contact.

Statistical methods / analysis
As part of this evaluation, we are aiming to interview 20 CRT users/family members. The interviews will be transcribed verbatim by the researcher (SK). Thematic analysis will be conducted in accordance with Braun and Clarke’s (2006) approach. We will independently read and code interview transcripts; codes will be examined and iteratively consented into groups capturing similar themes, each with a number of sub themes. These themes and sub themes will be considered by the wider team to validate the plausibility of the themes. To achieve saturation of themes, we will move back and forth between data collection and analysis, ensuring the fit between data and the conceptual work of analysis and interpretation. Interviews competed early in the study will inform subsequent data collection. We will use NVivo Software to assist with data organisation and analysis.

Brief summary
Police and ambulance services are increasingly the first responders to people in mental distress as mental-health related calls to 111 increase and mental health services struggle to meet the significant increases in demand. Apart from the demands this places on limited police resources, the lack of timely mental health expertise during a crisis negatively affects service users.

The objective of this study is to evaluate the implementation of an innovative mental health co-response team (CRT) that is being piloted in the Wellington region. Inspired by successful initiatives in Australia and the United Kingdom, the pilot involves staff from mental health services, Wellington Free Ambulance and the Wellington District Police being jointly deployed to respond to 111 calls made by or about someone requiring help in a mental health crisis. From March 2020 the CRT pilot has been providing front-line, first-response capability for the provision of in-situ mental health assessments and therapeutic care in a home or community setting rather than the person being transported to an emergency department (ED) or police station for mental health triaging.

As part of the evaluation, we are conducting qualitative research (face-to-face semi-structured interviews) with CRT service users and family/whanau about their views and experiences of the CRT. Our evaluation study will help service planners understand the benefits and gaps of CRT, including from the service user's perspective.
