<p>Practice Research on Reducing the Incidence of Chemotherapy-Induced Nausea and Vomiting in Patients by Applying PDCA Cycle Combined with Traditional Chinese Medicine Nursing</p>

Abstract: Objective To explore the application effect of PDCA cycle combined with traditional Chinese medicine (TCM) nursing intervention in reducing the incidence of chemotherapy-induced nausea and vomiting (CINV) in patients, so as to provide reference for clinical nursing practice. Methods A PDCA quality improvement team was established to intervene chemotherapy patients in the Third Ward of Bone Tumor through four-stage management of Plan, Do, Check, and Action, combined with TCM nursing techniques. Fifty chemotherapy patients in July 2025 (before improvement) were selected as the control group and received routine nursing; 50 chemotherapy patients from September to October 2025 (after improvement) were selected as the observation group and received PDCA cycle combined with TCM nursing intervention. The incidence of CINV and the improvement of related influencing factors were compared between the two groups. Results The incidence of CINV in the observation group decreased from 40% before improvement to 16%, with a target achievement rate of 114.29% and a progress rate of 60%; the proportions of main influencing factors such as psychological factors and drug factors decreased significantly, and the patients’ nursing satisfaction and nurses’ comprehensive ability were improved.Conclusion PDCA cycle combined with TCM nursing can effectively reduce the incidence of CINV in chemotherapy patients, improve the patients’ treatment experience, and is worthy of clinical promotion and application.
