Abstract: Objective: To explore the effectiveness of a nutritional education pathway based on feed forward control concepts during radiotherapy in head and neck cancer patients. Methods: A convenience sampling method was used to recruit 131 head and neck cancer patients undergoing radiotherapy at a grade A tertiary hospital from July 2021 to August 2022. Among them, 65 patients from July 2021 to January 2022 were designated as the control group, and 66 patients from February to August 2022 weredesignated as the observation group. The control group received conventional radiotherapy nutritional care, while the observation group received a nutritional education pathway based on feed forward control concepts in addition to the standard care. Nutritional indicators and self-nutritional management ability scores were compared between the two groups at admission and discharge. Nutritional risk screening (NRS 2002) and subjective global assessment (PG-SGA) scores were assessed at admission, the third week of radiotherapy, and at discharge. Results: There were statistically significant differences between the two groups in terms of nutritional indicators, NRS 2002 scores, PG-SGA scores, and self-nutritional management ability at discharge (P<0.05). Conclusion: The nutritional education pathway based on feed forward control concepts helps to reduce nutritional risk, improve nutritional status, decrease the incidence of malnutrition, and enhance self-nutritional management ability in head and neck cancer patients undergoing radiotherapy.
