Co-producing Healthcare Interventions: Transforming Transdisciplinary Research to Develop Healthcare Services to Meet the Needs of Patients with Complex Problems

Patients with severe mental illness (SMI) and concurrent physical diseases have complex health problems that are often not handled optimally. The treatment and care take place across sector borders and this cross-sectorial cooperation often proves inadequate and deficient in the handling of patients with SMI and multimorbidity. In an on-going study of patients with severe mental illness (SMI) and concurrent physical diseases, a new attempt is being made at using co-production to develop useful and applicable integrated care models. The aim of this study (The Phy-Psy Trial/PPT) is to develop a care model that bridges the gaps between the health care sectors, while at the same time taking into account the perspectives of both the patients and their relatives. The co-production process developed for the PPT is described and discussed in this chapter.
