Introduction: Mental health illness represents one of the greatest health burdens in the world. It is well documented that treatment of these illnesses could be optimised through strengthened collaboration between general practice and specialised mental healthcare services (shared care). Furthermore, involvement of users in the design of new interventions to strengthen end-user value and sustainability is key. Therefore, the aim of this study is to develop a shared care intervention in co-production with users.
Methods and analysis: The study will take place at psychiatric outpatient clinics in Denmark.The project is described in four sequential steps, each informing and leading into the next: a systematic review (step 1) will be followed by an exploratory study investigating how stakeholders (general practitioners, mental healthcare staff and patients) perceive existing treatment and collaboration between general practice and mental health services. Steps 1 and 2 will inform and qualify the intervention that will be developed in step 3 as a co-creation study. Step 4 will assess the intervention in a feasibility study. Step 4 will be designed as a non-randomised intervention study with a control group with preassessments and postassessments. In total, 240 patients will be recruited. Questionnaires will be administered to the participants at their first visit to an outpatient clinic and again after 3 months. The primary outcome will be patients' self-reported mental health status (Short Form Health Survey, SF-36) and recovery (revised Recovery Assessment Scale, RAS-R). Recruitment will take place from June 2023 to May 2024.
Ethics and dissemination: The project is approved by the ethics committee (REG-016-2022). Informed consent based on written and verbal information about the aims, purpose and use of the study and the data collection will be obtained from all participants. The study findings will be published in peer-reviewed journals and presented at national and international conferences. The study is registered at ClinicalTrials.gov.
