This report presents the activities and results of the Digital Innovation for Dementia Care (DIDEC) project. The DIDEC project was initiated by Perstorp Municipality because of the compelling need to innovate the field of dementia care. Dementia is a challenge for affected individuals and their families as well as for health care services. New products and services, which can improve both the quality of life for people with dementia and the work of care providers, are asked for. The DIDEC project involved the development of a living lab at Österbo dementia care center (in Perstorp) which fostered the collaborative creation of innovations. Business stakeholders and health professionals were enabled to test new solutions in the daily life of the dementia care center. The project engaged various actors from Perstorp Municipality, Österbo, Science Parks, companies and academia, over a period of three years (2018-2020). Despite several challenges (e.g., staff resistance, technical problems, Covid-19), the project was perceived as very successful, entailing important learnings on how to manage change, good results (e.g., one complete real-life testing) as well as positive side-effects (e.g., better working climate). The findings from the project emphasize the four T:s that can explain the success of collaborative innovation projects, namely: Talk, Tolerance, Transparency and Trust.
