Aim: The objective of this scoping review was to summarize, understand and provide an overview of the empirical literature on interventions involving own treatment choice for people with coexisting diabetes (type 1 and 2) and severe mental illness (SMI). Methods: This scoping review undertook a systematic literature assessment. Searches were performed in MEDLINE, Embase, PsycINFO, Web of Science, CINAHL, the Cochrane Library and grey literature (OpenGrey, Google Scholar and Danish Health and Medicine Authority databases). Publications from 2000 to July 2020 were of interest. Studies were included if they involved the users’ own choice of treatment. Included studies: RCT, intervention, cohort and case-based studies. Results: A total of 4320 articles were screened, of which nine were included. The review identified eight studies from the United States and one from Canada testing different interventions for people with SMI and diabetes (one diabetes education program, five randomized controlled trials, one retrospective cohort study, one naturalistic intervention program and one case vignette). The interventions described in the nine articles involved service users, the majority incorporated individualized healthcare plans, and all interventions were based on multidisciplinary teamwork. Conclusions: Research in the area is limited. Care management interventions tend to focus on a single condition, paradoxically excluding SMI during enrolment. Interventions aimed at people with both conditions often prioritize one condition treatment leading to an unbalanced care.
