Establishing a nausea-free ward model to reduce chemotherapy-induced nausea and vomiting: A retrospective study

The objective of this study was to establish a nausea-free ward model and evaluate the effect of an intervention procedure guided by this model on chemotherapy-induced nausea and vomiting (CINV) in cancer patients. A total of 105 chemotherapy patients from March to September 2022 before the establishment of nausea-free ward in the Chongqing Jiulongpo District People's Hospital were selected as the control group as well as 105 chemotherapy patients from March to September 2023 after the establishment of nausea-free ward as the intervention group. The intervention group was managed by comprehensive standardized CINV management on the basis of the control group. Finally, the Chinese Society of Clinical Oncology grading tool for nausea and vomiting and the Functional Living Index-Emesis were used to evaluate the effect. Under the intervention of the nausea-free ward model, the intervention group exhibited significantly lower ratings of nausea and vomiting compared to the control group (all P-value <.05). The nausea score, vomiting score, and total score of the intervention group were significantly lower than the control group (all P-value <.05). Our study found CINV symptoms and quality of life can be significantly improved by the application of the nausea-free ward model. The nausea-free ward model is instructive in clinical practice and can guide clinical work as well as bring management experience to clinical workers.
