Abstract

Aims: The objectives of this study are to identify the proportion and characteristics of people with type 1 and 2 diabetes treated in primary, specialist and shared care and to identify the proportion of persons with type 2 diabetes reaching HbA1c treatment targets and the clinical risk factors and general practitioner and practice characteristics associated with treatment in specialist care.

Methods: Population-based cross-sectional study including all adults ≥18 years diagnosed with diabetes in primary and specialist care in Salten, Norway. We used multivariable mixed-effects logistic regression models with level of care as outcome variable and population, general practitioner, and practice characteristics as exposure variables.

Results: Of 2704 people with type 2 diabetes, 13.5% were treated in shared care and 2.1% in specialist care only. Of 305 people with type 1 diabetes, 14.4% received treatment in primary care only. The HbA1c treatment target of 53 mmol/mol (7.0%) was reached by 67.3% of people with type 2 diabetes in primary care versus 30.4% in specialist care. HbA1c , use of insulin, coronary heart disease, retinopathy and urban practice location were positively associated with treatment in specialist care. General practitioners' use of a structured form and a diabetes nurse were negatively associated with specialist care.

Conclusions: Of people with type 2 diabetes, 16% were treated in specialist care. They had higher HbA1c and more vascular complications, as expected from priority guidelines. The use of a structured diabetes form and diabetes nurses seem to support type 2 diabetes follow-up in primary care.
