Aims: This study explored clinicians' perspectives on roles, practices and service delivery in the dietary management of coronary heart disease and type 2 diabetes in a public health service.
Methods: Semi-structured individual interviews were conducted with 57 clinicians (21 nurses, 19 doctors, 13 dietitians and 4 physiotherapists) involved in the care of relevant patients across hospital and post-acute community settings in a metropolitan health service in Australia. Interviews were audio-recorded, transcribed verbatim and analysed using inductive thematic analysis.
Results: A total of 3 themes with 10 subthemes were identified. (a) 'Treatment prioritisation': important role of nutrition in risk factor management; competing priorities with complex patients; weight loss as a priority; and dietitians individualise. (b) 'Diverse roles in providing diet advice': a tension between nutrients, restrictions and diet quality; patients seek and trust advice from non-dietitians; and providing nutrition information materials crosses professions. (c) 'Dietitian access': variable integration and resourcing; access governed by clinician discretion and perceived patient interest; and bespoke application of referral pathways.
Conclusions: Time and resource constraints, variable access and referral to dietitians, and inconsistent advice were key challenges in the dietary management of coronary heart disease and type 2 diabetes. Models of care may be improved with greater investment and integration of dietitians, including to provide professional support across disciplines and disease specialties.
