Abstract:Objective：To explore the application effect of two-dimensional code based electronic propaganda in health education of cancer pain patients. Methods：120 patients with malignant tumor pain were selected as the study subjects，half of them as control group who were hospitalized in the department of oncology from January to March 2020，and another part of them as experimental group who were hospitalized in the department of oncology from April to June 2020. Health education was conducted for patients with cancer pain based on two-dimensional code designed by ourselves. The knowledge of pain publicity and education of patients in the two groups as well as the time of nurse publicity andpaineducation of patients in the two groups were compared. Results：All the 60 patients had good pain control effect，and the knowledge of health propaganda and education of cancer pain in the experimental group was significantly higher than that in the control group（P < 0.05），and the time of propaganda and education of nurses was significantly less than that in the control group（P < 0.05）. Conclusion：Healtheducation based on two-dimensional code can help cancer patients to master cancer pain related knowledge and reduce the time of nurses'health education.
