Plain language summary
Patients with upper gastrointestinal (UGI) cancer (oesophagus, gastric, and pancreas) are vulnerable to malnutrition. Symptoms of the cancer and its treatment are barriers to usual eating patterns that contribute to unintentional weight loss. The aim of this study was to explore the patient-dietitian experience of an 18-week nutrition intervention (the TEND study) delivered using the telephone and a mobile application to people newly diagnosed with UGI cancer to elucidate the roles of the dietitian. This study was an analysis set within the TEND study (a three-arm randomised controlled trial exploring the impact of delivering an 18-week intensive nutrition intervention to patients newly diagnosed with UGI cancer). Participants were allocated to receive the intervention using either the telephone or a mobile application, myPace. Results showed that: - rapport can be built within the patient-dietitian relationship without face-to-face communication. - the roles of the dietitian were characterised by regular collaborative problem-solving to encourage empowerment, a reassuring care navigator (including anticipatory guidance), and rapport building via reliable psychosocial support. - that role limitations led to unmet needs as the dietitian was constrained by poorly managed cancer symptoms that negatively impacted oral intake and subsequently weight stability. Authors concluded that more research is needed to examine an advanced care role for dietitians in the management of nutrition impact symptoms.
Abstract
PURPOSE This study aimed to explore the patient-dietitian experience during an 18-week nutrition counselling intervention delivered using the telephone and a mobile application to people newly diagnosed with upper gastrointestinal (UGI) cancer to (1) elucidate the roles of the dietitian during intervention delivery and (2) explore unmet needs impacting nutritional intake. METHODS Qualitative case study methodology was followed, whereby the case was the 18-week nutrition counselling intervention. Dietary counselling conversations and post-intervention interviews were inductively coded from six case participants which included fifty-one telephone conversations (17 h), 244 written messages, and four interviews. Data were coded inductively, and themes constructed. The coding framework was subsequently applied to all post-study interviews (n = 20) to explore unmet needs. RESULTS Themes describing the roles of the dietitian were as follows: regular collaborative problem-solving to encourage empowerment, a reassuring care navigator including anticipatory guidance, and rapport building via psychosocial support. Psychosocial support included provision of empathy, reliable care provision, and delivery of positive perspective. Despite intensive counselling from the dietitian, nutrition impact symptom management was a core unmet need as it required intervention beyond the scope of practice for the dietitian. CONCLUSION Delivery of nutrition care via the telephone or an asynchronous mobile application to people with newly diagnosed UGI cancer required the dietitian to adopt a range of roles to influence nutritional intake: they empower people, act as care navigators, and provide psychosocial support. Limitations in dietitians' scope of practice identified unmet patient's needs in nutrition impact symptom management, which requires medication management.
