Abstract

This study aimed to acquire a comprehensive understanding of the experiences and needs of healthcare professionals (HCPs) in a university medical center at the medical oncology department regarding the provision of uniform information on nutrition and nutritional supplements to adult patients with cancer.
This explanatory sequential mixed-methods study employed an online questionnaire that was sent to HCPs and included questions on indications for providing nutrition advice, knowledge about nutrition and nutritional supplements, and needs regarding providing uniform advice about these topics. This was followed by semi-structured interviews with HCPs to gain deeper insights into their experiences and needs.
Thirty-two HCPs completed the questionnaire, and nine HCPs participated in semi-structured interviews. The results identified five themes: knowledge of nutrition and nutritional supplements, interdisciplinary care, patient-centered care, information sources, and (scientific) basis of nutrition information and research.
This study shows that HCPs express a need for enhanced knowledge and greater consistency in nutritional care during cancer care. Although HCPs reported confidence in their general nutrition knowledge, they were less familiar with nutritional supplements. Education, awareness of guidelines, access to evidence-based information, a clearer division of roles between HCPs, and interprofessional collaboration are key to improving confidence, quality, and delivering personalized nutritional support in cancer care.
