Abstract

In order to avoid the problems of incomplete analysis process, non-assessment of risks in some processes and failure of countermeasures to achieve the expected results in the application of a single quality control circle, in this study, quality control circle, medical failure mode, effect analysis method and root cause analysis method were compared in order to find the similarities, differences, advantages and disadvantages between them. A three-dimensional tool synthesis model based on quality control circle was formed by combining these three factors, and the model was applied to the nursing of patients with indwelling nasogastric tube. The results showed that this three-dimensional tool synthesis model could effectively reduce the probability of extubation of nasogastric tube (p<0.05), alleviate the pain suffered by patients in the course of treatment, reduce the cost of indwelling nasogastric tube consumables and nursing time (p<0.05), thus greatly improve the work efficiency of medical staff and effectively enhance the comprehensive ability of nurses (p<0.05). Hospital operation and management systems were also optimized. This study improved the nursing process of patients with indwelling nasogastric tube and provides a theoretical basis for the humanization and advancement of medical management.
