The psychosis and type 2 diabetes service model (PODS) population profile study

To describe diabetes care received and views of people with severe mental illness (SMI) and type 2 diabetes (T2D) in an inner-city primary care setting.

A cross-sectional study of adults with SMI and T2D from two primary care localities in south London.

Medical record data was extracted on annual diabetes review and participants invited for telephone interview.

125 adults participated, 37 completed interviews. 43 % were female, 48 %, 35 % and 16 % were: Black African/Caribbean, White, Asian/other ethnicity. Mean age= 59.47 years (SD:12.68), diabetes duration= 8.62 years (SD:6.10), systolic blood pressure (BP)= 133.42 mmHg (SD:17.28), diastolic BP= 81.42 mmHg (SD:8.93), BMI= 33.17 m/kg² (SD:7.22), HbA1c= 61.64 mmol/mol (SD:25.18). Older age (OR:1.06, 95 % C.I.:1.0, 1.10), shorter diabetes duration (OR:0.90, 95 % C.I.:0.84, 0.97) were associated with target HbA1c< /= 58 mM. Younger age and Black ethnicity were associated with BP> 140 mmHg (OR:0.94, 95 % C.I.:0.90, 0.98; OR:0.08 (95 % C.I.:0.01, 0.56). Being older was associated with cholesterol, < 5.0 mmol/mol (OR:1.06, 95 % C.I.:1.01, 1.11). Questionnaires demonstrated low physical activity, alcohol/drug use, diabetes distress, psychiatric symptoms. Interviews indicated that > 50 % wanted more support with SMI and T2D.

Younger, black people with SMI and T2D are potentially at greater cardiometabolic risk. Interviews suggest people with T2D and SMI group require more mental health and diabetes support.
