Abstract: Objective: To apply the evidence of assessing the location of nasogastric tube end for children to clinical practice and evaluate its application effects, so as to provide a reference for standardizing the assessment of nasogastric tube end position of pediatric nurses and improving the quality of specialized catheter nursing. Methods: According to the evidence transformation model issued by the evidence-based nursing center of Fudan University, we summarized the evidence regarding nasogastric tube end position assessment for children to formulate the corresponding clinical indexes for assessment. After analysis of obstacle factors in the process of implementation, we figured out proper strategies to implement the evidences. Then we compared the accuracy of nasogastric tube end position assessment, the incidence of nasogastric tube detachment, the implementation rate of each index and nurses' knowledge of nasogastric tube related operation and position assessment before and after the application of evidence. Results: Five indicators were established in this study. Nurses' compliance to apply the evidence was improved as well as their knowledge of nasogastric tube insertion with the differences being statistically significant (P<0.001). The accuracy rate of nasogastric tube end position assessment for children increased from 81.81% to 97.1% and the incidence of nasogastric tube detachment reduced from 24.2% to 2.9% with statistically significant differences (P<0.05). Conclusion: Applying the evidence of assessing the location of nasogastric tube end for children not only provides reference for clinical decision making, but also improves the evidence-based nursing knowledge and adherence to evidence for nurses to effectively increase the accuracy rate to locate nasogastric tubes for children, reduce the incidence of accidental nasogastric tube detachment, which can promote the quality of pediatric nursing.
