BACKGROUND: Primary healthcare is the ideal setting to address diet-related disease through delivery of nutrition services. However, quality nutrition care has not previously been defined from the healthcare consumer perspective. OBJECTIVES: To explore, and develop a theoretical model of, healthcare consumer expectations of quality nutrition care in the primary healthcare setting. METHODS: A qualitative study design collected data describing healthcare consumer expectations of nutrition care. Consumers were recruited through social media and research networks, screened, and invited to participate in a semi-structured telephone interview. Interviews explored experiences and views of nutrition care. Interviews were thematically analysed, and informed development of a model using an iterative process. RESULTS: Twenty-three healthcare consumers participated in an interview. Five themes were identified. The Quality in Nutrition Care consumer model developed from these themes comprised 5 interconnected components, these being: (i) quality nutrition care occurs within an integrated societal system; (ii) quality nutrition care is available, accessible, and affordable; (iii) quality nutrition care is up-to-date and evidence based; (iv) quality nutrition care is underpinned by positive relationships; and (v) quality nutrition care is personalized to consumer needs. CONCLUSIONS: The consumer-derived model of quality nutrition care can be used by providers to inform activities that enhance primary healthcare practice, outcomes, and impact. The model has important implications for primary healthcare system reform and policy. Future research should explore the provision of dietetic services in primary care, with specific focus on factors that influence quality care, and investigate how quality is monitored and improved.
