Background Type 2 diabetes demands self-management over time, to maintain health and reduce the risk for diabetes complications. However, despite efforts, many persons with type 2 diabetes are not reaching the treatment targets. In diabetes, person-centred care and group education are recommended. Diabetes specialist nurses (DSNs) working in primary healthcare have an important role in supporting patients with type 2 diabetes in their self-management to adapt to the demands of the disease in everyday life. Therefore, it is important to explore the DSNs’ professional role and their experiences of practising person-centred care. The overall aim of the thesis was to explore the professional role of DSNs in primary healthcare, and to describe their experiences of person-centred diabetes care.

Methods The thesis includes three studies with qualitative, and one with a quantitative, approach. Data collection consisted of focus group interviews, individual interviews, observations, and questionnaires. Qualitative content analysis and statistics were used in the analysis. In studies I and II, 29 and 31 DSNs participated, respectively. In study III, 10 DSNs and 44 persons with type 2 diabetes participated. Lastly, in study IV, 10 DSNs participated.

Results The results in the thesis showed that DSNs have a complex and multifaceted professional role that entails striving to be an expert, a fosterer, a leader, an executive, and a role model, which they found challenging. The DSNs perceived high job demands, such as decision-making and learning. The thesis also showed that the interaction between DSNs and persons with type 2 diabetes shifted from empowerment to authority struggles during group support sessions based on person-centred care. The experience of person-centred care was described as enriching, but DSNs also expressed ambivalence, related to an altered professional role.

Conclusion There is a desire by DSNs to be close to persons with type 2 diabetes, although they have several challenges to fulfil, which makes it difficult to uphold a relation with proximity; thus, distance is also present. Even though person-centred care is recommended in healthcare, and despite DSNs’ efforts to practise PCC, the result of this thesis shows that it also implies an altered professional role for DSNs that has to be addressed.
