How do healthcare providers support people with prediabetes to eat well? An in-depth, mixed-methods case study of provider practices.

BACKGROUND AND OBJECTIVES:Guidelines recommend people with prediabetes receive diet and lifestyle support to avoid type 2 diabetes, yet it is unclear whether this care is provided in practice. The aim of this article is to explore the perspectives and nutrition care practices of healthcare providers (HCPs) for patients with prediabetes. METHOD:This was a mixed-methods case study of an urban practice comprising a retrospective chart review and semi-structured interviews. Charts of adult patients with prediabetes were reviewed and informed a protocol used to interview HCPs. Interviews were thematically analysed. RESULTS:Charts of 47 patients, representing 1096 consultations, were reviewed. The majority (74.5%) of patients had 'diet' noted in their chart, yet this accounted for only 8.1% of consultations. Only 19.1% of patients were referred to a dietitian. Interviews provided HCP explanations of the quantitative findings. DISCUSSION:HCPs value nutrition care, yet are limited by the healthcare system to provide comprehensive care to people with prediabetes.
