Quality evaluation index development for nutritional management in patients with nasopharyngeal carcinoma during peri-radiotherapy

It is necessary to construct an evaluation index for patients with nasopharyngeal carcinoma during peri-radiotherapy to provide a reference for the evaluation of the quality of nutritional management of patients with nasopharyngeal carcinoma during peri-radiotherapy. The aim of this study was to construct a set of scientific, comprehensive, and feasible indicators for evaluating the quality of nutrition management in patients with nasopharyngeal carcinoma during peri-radiotherapy to provide a unified reference basis for objective nutritional evaluation of these patients during the peri-radiotherapy period and to provide insights to the clinical treatment and care of these patients.A multidisciplinary research team was set up from December 2021 to April 2022. We took the three-dimensional quality structure model as the theoretical framework; based on the literature review, the first draft of the nutrition management quality evaluation index for patients with nasopharyngeal carcinoma during peri-radiotherapy was formed by a semi-structured interview. The Delphi correspondence method was used to survey 18 experts from 12 cities in China. The multidimensional analytical hierarchy process was used to determine the evaluation index and weight of nutrition management quality of patients with nasopharyngeal carcinoma during peri-radiotherapy.The effective questionnaire recovery rates of the two rounds of letters were 90.005% and 100%, respectively, and the expert authority coefficients were 0.906 and 0.918, respectively. The Kendall harmony coefficients of the two rounds of letters were 0.271 to 0.313 and 0.309 to 0.349, respectively. The nutrition management quality evaluation index of patients with nasopharyngeal carcinoma during peri-radiotherapy was constructed and included 3 first-level indexes, 10 second-level indexes, and 71 third-level indexes.The evaluation index of the nutrition management quality of patients with nasopharyngeal carcinoma during peri-radiotherapy is scientific and reliable, and it may have a certain guiding significance for nurses to evaluate the quality of nutrition management of these patients during this period.
