People with co-morbidity are people with both a mental illness and an addiction problem. The Government’s 2023 Co-morbidity Inquiry reinforces the picture of the difficulty of providing the right support to the target group. Lack of interaction between authorities and within authorities and lack of knowledge about each other's activities are pointed out as some of the reasons that hinder a coherent care chain. Many people with comorbidities end up in a lifelong exclusion where shame and self-stigma become major obstacles to seeking support. In Karlskrona municipality, we see that we currently lack a coherent support process for people with co-morbidity. This makes it more difficult for the target group to find the way from exclusion to a meaningful everyday life and an independent life. We also lack an adapted and strengthened intermediate step between idle and a permanent participation in one of our regular occupations, or studies and work. The reinforced activities should be based on our community premises and housing first and provide the participants in the project with individualized support to identify strengths, needs and wishes, receive peer support, support talks and receive training in social skills. The whole process should be developed by using service design/user driven innovation as a method. This means that participants build their own support process and design their own employment. We use case management as a way of working/method to provide support, follow up, follow up and ensure that the participants receive adequate support throughout their development process. The overall goal of the project is to use service design / user-driven innovation to develop a support process and design the content with the individual in focus. That gives people with comorbidities increased opportunities and conditions to have an independent and meaningful life in Karlskrona municipality.
