Objective: To explore the application of PDCA circulatory model in hospital digestive endoscopic nursing and its application. Methods: 48 patients were randomly selected from the control group, and the patients were treated with a routine nursing operation. Eight patients with digestive endoscopy were selected as the observation group. On the basis of the implementation of general care and then increase the PDCA cycle model, and then the two groups of patients with a detailed comparison of care and research. Results: The nursing quality and satisfaction of the observation group were higher than those of the control group, and the contrast difference was significantly improved (P < 0.05). Conclusion: The full application of PDCA circulatory model in digestive endoscopic nursing can effectively improve the quality of care for patients, and also improve the satisfaction of patients to a certain extent.
