Eliciting the mechanisms of action of care navigators in the management of type 2 diabetes in people with severe mental illness: A qualitative study.

BACKGROUND: People with severe mental illness and type 2 diabetes have a reduced life expectancy compared to the general population. One factor that contributes to this is the inability to provide optimal management, as the two conditions are typically managed by separate physical and mental health systems. The role of care navigators in coordinating diabetes care in people with severe mental illness may provide a solution to better management. AIM: To explore the views of clinicians and people with severe mental illness and type 2 diabetes on an integrated health service model with a focus on the care navigator to identify potential mechanisms of action. DESIGN: Qualitative one-to-one semi-structured interviews and part of a wider pilot intervention study. SETTING: Community Mental Health Unit in South London. METHOD: Topic guides explored the perspectives and experiences of both clinicians and people with severe mental illness and diabetes. Data analysis was conducted using Thematic Analysis. RESULTS: From the analysis of 19 participants, five main themes emerged regarding the care navigator role: administrative service; signposting to local services; adhering to lifestyle changes and medication; engaging in social activities; further skills and training needed. The key findings from this study emphasise the benefits that the role of a care navigator has in helping people with severe mental illness to better manage their diabetes i.e. through diet, exercise medication and attending essential health check-ups. CONCLUSION: This study illustrates that having a care navigator in place empowers those with severe mental illness to improve the management of their diabetes. Future research should focus on the extent to which care navigators are effective in improving specific outcomes.

Exploring healthcare professionals' perspectives of barriers and facilitators to supporting people with severe mental illness and Type 2 diabetes mellitus.

Individuals with comorbid severe mental illness (SMI) and diabetes experience an average mortality gap of 20 years compared to individuals without these conditions. There has been some recognition by policies that there is a gap between mental healthcare and physical healthcare for SMI patients. Despite this, there are still no defined care pathways for individuals with SMI and diabetes. The aim of this study was to explore healthcare professionals' (HCPs) perspectives of barriers and solutions to supporting people with SMI and diabetes. HCPs in areas of South London were invited to attend a workshop event to discuss their views of SMI and diabetes pathways. Fifty participants were recruited using the Local Care Network. HCPs included GPs, mental health nurses, psychiatrists, diabetologists and care co-ordinators. The main themes were as follows: (a) poor coordination of care and care planning between services; (b) key techniques to improve integrated care; (c) perceived difficulties achieving better care and (d) supporting patient empowerment. The findings and recommendations from this workshop may provide some insight into key factors in providing and improving integrated SMI and diabetes care for patients in South East London and further afield.
